    Suppository inserter Field of the invention The present invention relates to a suppository inserter for inserting suppositories into bodycavities.
    Background of the invention ln the medical care industry as well as in home treatment, there are numerous different waysby which a medicine can be applied to a patient. For instance, medicine can be administeredby swallowing, injecting, inhaling or inserting into a body cavity. When the medication isneeded to penetrate into and gradually be absorbed by the body, suppositories which can beintroduced into an appropriate body cavity have been especially efficient. ln particular, rectalsuppositories have been used in order to administer a predetermined drug dosage to treat avariety of diseases and symptoms in a variety of patient populations. Certain medicalconditions, such as digestive disorders, may be more efficiently treated when the suppositoryis placed in a particular location of the patient's anal canal or rectum.
    When suppositories are applied in the health care, physicians many times use manualapplications to aid in inserting the suppository into the body cavity. This application ispreferable because suppositories provide a reliable, safe and hygienic means for controllingthe insertion. ln addition, suppository applications enable a patient to conveniently use themfor self-insertion even when a doctor is not present. To accomplish their purpose, mostsuppositories typically constitute of a tubular body which holds the suppository whereas apiston or plunger is manually applied through the tube to push and insert the medication intothe passage ofthe cavity. ln clinical practice, sanitary applicators made of plastic materials areemployed with increasing frequency. These medical aids are predominantly intended for asingle use, and the procedures with them are conducted under either sterile or unsterileconditions. The most prevalently applied devices are, for instance, sterile hypodermic plasticsingle-use syringes.
    However, there is a problem when suppositories are applied outside the health care andhospitals by unexperienced persons and in home environments. For example, when parentsare about to insert suppositories into their children in order to reduce a fever. lt is confusinghow to introduce the suppository into the children. This results in that several parents changeto liquid or tablet form, even though this does not always work or has poorer effect on thefever. The confusion prevails among other things, which end of the suppository is to beinserted first, the blunt end or the pointed end, how to hold the suppository, and how to insertit far enough to avoid irritating the intestinal and to avoid that the suppository comes outbefore it has been completely dissolved.
    From US 3823715 it is known that an introducer for suppositories is devised as a syringe andhas a tubular body with a forward necked-down inserting section and a rear, pressure-generating section in the form of a cylinder within which there reciprocates a pressure-generating piston. The forward end of the piston is extended into a forward portion having asmaller, effective diameter, such forward section fitting within the necked-down insertingsection ofthe body.
    From US 4990136 (A) it is known that a suppository applicator comprising a tubular body withan open and a closed end is devised to insert suppositories into body cavities. A plunger isslidably disposed in the tubular body for reciprocal movement between a withdrawn positionand an extended position. Unfortunately, this kind of mechanically-driven syringe is way toocomplex, it is complicated and expensive to manufacture and is thus cost-inefficient.
    Another example of suppository appliance is shown in DE156679 (A1). This is a one-piecedevice made of elastic material comprised in one module. The front part with a piston has anopening to receive the suppository and the rear part is balloon-shaped. ln order to eject thesuppository, the rear part has to be pressed. Due to its elasticity the rear part is compressed,which causes the piston to be moving toward the opening and by that the suppository isejected.
    The disadva ntage with all the three above-mentioned modifications of su ppository techniquesis that they are all produced for a certain size of suppository and today we have in general alot of diverse sizes of suppositories manufactured by different suppliers. This createsinconvenience while a different suppository size must be used.
    Obiect and summary of the invention lt is an object of the present invention to at least partly overcome the above problems, and toprovide an improved device for insertion of a suppository.
    This object is achieved by a device as defined in claim 1.
    The device com prises a body, a piston slidably inserted in the body, and an top section havingan opening for receiving a suppository and including a tubular part defining a cavity having afirst end for receiving the suppository and a second end for receiving the piston, and the bodycomprises a pressure generating section for generating a pressure on the piston to achieve areciprocal movement ofthe piston between a first withdrawn position and a second extendedposition. The invention is characterized in that the top section is removably attached to thebody. The top section comprises a cover attached to the tubular part and the cover isremovably attached to the body.
    According to the invention, the top section is removably attached to the body. Due to the factthat the cover is removably attached to the intermediate part, instead of the tubular part being removably attached to the body, the design and position of the tubular part can bevaried without the need of changing the length of the piston or the size of the body.Accordingly the size ofthe cavity for receiving a suppository can be varied so that it is adaptedto the size of the suppository. The same body and the same piston can be used for differentsizes of suppositories. The only part that has to be changed is the top section. Thus there is agreat flexibility achieved, because different sizes of suppository can be used with one and thesame device, according to the invention.
    Both the position and the size of the tubular part can be adjusted to the suppository size. Thecover is attached to the body and is enabled to be made of different lengths.
    The body and the cover is provided with attachment means adapted to cooperate with eachother to allow the cover to be removably attached to the body. Examples of suitableattachment means are snap-fittings, and bayonet fittings.
    According to an embodiment of the invention, the body comprises a plurality of replaceabletop sections designed for receiving suppositories of different sizes. For example, each of thetop sections has a cover with a length that differs from the length of the covers of the othertop sections. For example, the inner diameters of the tubular parts may have different sizes.An apparent advantage is that the replaceable top sections make it possible to adapt todifferent sizes of suppositories. Owing to the fact that the cover and the body is provided withattachment means to removably attach the cover to the body, there could be designed tubularparts and covers in different sizes depending on the suppositories size. The suppositoryinserter is thus very cost-effective. This in contrast to having specific devices for each specificsuppository size. lt is to be appreciated that the distance between an upper part of the pistonand the first end of the tubular part can be varied depending on the type of suppository. As itwill be appreciated by ordinary consumer, suppositories vary in size and shape depending ontheir intended use and the particular manufacturer. Besides, the present applicator is not fora single use as the replaceable top sections are changeable while the main inserter is the same.
    According to an embodiment of the invention, the cover is arranged to surround the tubularpart and the cover is coaxially arranged with the tubular part. Suitably, the cover is attachedto an upper portion ofthe tubular part.
    According to an embodiment of the invention, the cover is conically shaped and arrangedcoaxially with the tubular part, and the cover is tapering towards the opening of the topsection. The cover surrounds the tubular part that is disposed along an axis of symmetry ofthe cover. Due to the conical shape, the risk for injuring the baby during the insertion of thesuppository is eliminated.
    According to an embodiment of the invention, the second end of the tubular part protrudesbelow a lower end of the cover.
    According to an embodiment of the invention, the piston comprises a piston head and a pistonrod including a front portion and a rear portion. Each of the piston head and the piston rodhas a smaller radial width than the tubular part so that the piston head and the front portionare slidably fitted in the tubular part. The rear portion has a larger radial width than the secondend of the tubular part so that the rear portion is prevented from being inserted into thetubular part. The total length ofthe front portion and the piston head is larger than the lengthofthe tubular part so that at least a part ofthe piston head will protrude from the tubular partwhen the piston is in the second extended position. With a radial width ofthe piston is meantthe largest width of the piston in a radial direction. For example, the rear portion is providedwith projections protruding in a radial direction and the radial width ofthe projections is largerthan an inner diameter of the tubular part and thus preventing the rear portion from beinginserted into the tubular part. Thus, the sliding movement of the piston is stopped when therear portion ofthe piston is in contact with the second end ofthe tubular part. Due to the factthat a part of the piston head protrudes from the top section when the sliding movement ofthe piston is stopped, the distance the suppository is inserted in the body cavity is always thesame and can be adapted to a suitable distance long enough to ensure that the suppositorywill stay in the body cavity until the suppository has been completely dissolved. The rearportion of the piston and the second end of the tubular part cooperate to stop the slidingmovement of the piston towards the insertion opening when the piston head is protruding adefined distance from the top section.
    According to an embodiment of the invention, the piston head protrudes at least 5 mm andpreferably at least 7 mm from the top section when the piston is in the second extendedposition. With manually applied force, for example through an operating button, the pistonejects the suppository at a minimum of 5 mm, preferably 7 mm and thus it is guaranteed thatthe suppository will be ejected long enough to ensure that the suppository will stay in thebody cavity until the suppository has been completely dissolved. Preferably, the piston headprotrudes less than 12 mm from the top section. Thus, it is ensured that the suppository is notinserted too long in the body cavity.
    According to an embodiment ofthe invention, the piston head is cylindrical and a diameter ofthe piston head is at least 10% smaller than an inner diameter ofthe tubular part. Preferably,the diameter of the piston head is at least 30% smaller than the inner diameter of the tubularpart. Thus, the width of the piston head is substantially smaller than the width of thesuppository. This design prevents injuring of the human body while operating with thesuppository inserter to insert suppository into the body cavity.
    According to an embodiment of the invention, the body comprises an intermediate sectionhaving a rear end attached to the pressure generating section and a front end removablyattached to the cover of the top section, and device comprises a tubular guiding member forguiding the piston, wherein the guiding member is disposed inside the intermediate sectionand arranged coaxial with the tubular part of the top section, and the piston being slidably inserted in the guiding member. The guiding member is designed to house and guide thepiston towards the tubular part of the top section.
    According to an embodiment ofthe invention, the guiding member has a larger diameter thanthe tubular part, and an upper end of the guiding member is designed to receive the secondend of the tubular part. When the top section is attached to the body, the second end of thetubular part is inserted in the upper end of the guiding member. By that the tubular part andthe guiding member form a passage for the piston towards the insertion opening.
    According to an embodiment of the invention, a wall of the pressure generating section ismade of a resi|ient material and an outer end of the piston rod is connected to the wall.Suitably, the outer end of the piston rod is removably connected to the wall. Due to theresi|ient material, the wall of the pressure generating section can by compressed when thepiston is moved to the second extended position. Preferably, the wall is made of material suchas washable and durable soft plastic, which is of sufficient strength to house the piston of thesuppository inserter. The sliding of the piston both inwardly and outwa rdly of the body of theinserter is possible as a result of elastic deformation of the resi|ient material of the wall.
    According to an embodiment of the invention, an operating button is attached to an outerend of the piston rod and disposed on the outside of said wall. The operating button is usedto manually move the piston towards the insertion opening and by that eject the suppository.
    According to an embodiment of the invention, the operating button is disc shaped and thewall of the pressure generating section is provided with an opening for receiving the pistonrod, and a diameter of the operating button is larger than a diameter of the opening in thewall. By that the piston can be inserted into and removed from the pressure generating sectionthrough the opening in the wall.

    Detailed description of preferred embodiments of the invention Referring primarily to figure 1, a device for insertion of a suppository, in the following namedsuppository inserter 1, according to an embodiment the present invention is displayed. Asseen in figure 1, the suppository inserter 1 comprises a body 2 and a top section 4 having aninsertion opening 8 for receiving a suppository. The top section 4 is removably attached to thebody 2. The top section 4 comprises a cover 5 removably attached to the body. The body 2comprises a pressure generating section 12. ln this embodiment, the body further comprisesan intermediate section 10. The intermediate section 10 has a rear end 14 attached to thepressure generating section 12 and a front end 16 removably attached to the cover 5 of thetop section 4. The suppository inserter 1 is conically shaped and is tapering towards theinsertion opening 8. The body 2 is rotationally symmetric and is tapering towards the topsection 4. The cover 5 is conically shaped and is tapering towards the insertion opening 8. Thepressure generating section 12 has a wall 20 made of a resilient material, such as a soft plasticmaterial or fabric. The cover 5 and the intermediate section 10 are made of a non-elasticmaterial, such as a hard plastic material. The suppository inserter 1 comprises an operatingbutton 22 for ejecting the suppository. The intermediate section 10 is provided with grippingmeans in the form of two recesses 24 disposed on opposite sides ofthe body 2.
    Figures 2 and 3 show cross-sections through the suppository inserter shown in figure 1. Figure2 shows the suppository inserter in a withdrawn position and figure 3 shows the suppositoryinserter in an extended position. ln the figures, the same and corresponding functional partsare designated by the same reference numerals. As seen from the figures 2 and 3, the body 2is hollow and constitutes a housing of the suppository inserter 1. The suppository inserter 1further comprises a piston 6 slidably inserted in the body 2 and movable between a firstwithdrawn position, as shown in figure 2, and a second extended position, as shown in figure3. The pressure generating section 12 is designed for generating a pressure on the piston 6 toachieve a reciprocal movement of the piston 6 between the first withdrawn position and thesecond extended position. As shown in figure 3, the piston head protrudes a distance L3 fromthe insertion opening 8 of top section 4 when the piston 6 is in the second extended position.Preferably, the distance L3 is between 5 mm and 12 mm, more preferably the distance L3 isbetween 7 mm and 12 mm. For example, the distance L3 is 9 mm.
    Figure 4 shows the top section 4 in more details. The top section 4 comprises the cover 5 anda tubular part 9 attached to the cover and extending inside the cover along an axis ofsymmetry of the cover. The cover 5 is conically shaped and arranged coaxial with the tubular part 9, and the cover 5 is tapering towards the first end of the tubular part 9. ln thisembodiment the tubular part 9 is circular cylindrical with an even inner diameter dl. However,in another embodiment, the tubular part can have different diameters along its length. Forexample, the diameter ofthe second end 32 ofthe tubular part can be less than the diameterof the first end 30 of the tubular part. The tubular part 9 defines a cavity 28 for housing thesuppository. The tubular part 9 has a first end 30 for receiving the suppository and a secondend 32 for receiving the piston 6. The first end 30 of the tubular part includes the insertionopening 8. As seen from figure 2, the second end 32 of the tubular part extends into the body2. The tubular part 9 is surrounded by the cover 5. The tubular part 9 and the cover 5 arecoaxial. The cover 5 is provided with attachment means 33 adapted to cooperate withcorresponding attachment means of the body to allow the cover to be removably attached tothe body. ln this example, the attachment means 33 of the cover is an inwardly protrudingflange surrounding a rear end ofthe cover. Examples of suitable attachment means are snap-fittings, and bayonet fittings. The cover 5 is removably attached to the front end 16 of theintermediate section 10 ofthe body.
    Figure 5 shows a perspective view of the suppository inserter with the top section removed.The front end 16 of the intermediate part 10 of the body is provided with attachment means34 adapted to cooperate with the attachment means 33 of the cover. ln this example, theattachment means 33 of the body is a plurality of snap fittings arranged along a periphery ofan opening of the front end 16 of the intermediate section 10.
    Figure 6 shows the piston 6 in more details. The piston 6 includes a piston head 40 and a pistonrod 42. The piston head 40 has a smaller radial width w1 than a diameter d ofthe tubular part9 so that the piston head is movable inside the tubular part. The piston rod 42 includes a frontportion 44 having a smaller radial width w2 than the inner diameter d1 of the tubular part 9so that the front portion 44 is slidably fitted inside the tubular part, and a rear portion 46having a larger radial width w3 than the second end 32 of the tubular part 9 so that the rearportion 46 is prevented from being inserted into the tubular part 9. Thus, the second end 32of the tubular part 9 defines a stop for a forward movement of the piston. When the rearportion 46 of the piston has reached the second end 32 of the tubular part 9, the piston hasreached the second extracted position as shown in figure 3. The total length L2 of the frontportion 44 and the piston head 40 is larger than the length L1 of the tubular part 9 so that atleast a part L3 of the piston head 40 will protrude from the tubular part 9 when the piston 6is in the second extended position, as shown in figure 3. The radial width w1 of the pistonhead is at least 10% smaller, preferably and at least 20% smaller than the diameter d of thesecond end of the tubular part. Thus, the radial width w1 of the piston head is smaller thanthe diameter of the suppository. A front edge of the rear portion 46 of the piston forms ashoulder 48 adapted to be in contact with an outer edge of the second end 32 of the tubularpart. ln this embodiment, the piston 6 comprises four wings 47 made in the form of a cross,disposed at right angles with respect to each other and extending along the length of thepiston. The radial heights ofthe wings 47 are different in the piston head 40, the front portion44, and the rear portion 46 of the piston. The radial height ofthe wings in the rear portion 46is larger than the radial height ofthe wings in the front portion 44, and the radial height ofthewings in the front portion 44 is larger than the radial height of the wings of the piston head40. The front edges ofthe wings ofthe rear portion 46 ofthe piston form shoulders 48 adaptedto be in contact with an outer edge ofthe second end 32 ofthe tubular part.
    The piston further comprises a cylindrical part 50 disposed at the end of the front portion 44and adjacent to the piston head. The cylindrical part 50 has a diameter that is slightly less thanthe inner diameter dl of the second end of tubular part to enable a smooth gliding movementof the piston in the tubular part. ln this embodiment, the piston head comprised four wingsarra nged so that the piston head has a cruciform cross section. ln an alternative embodiment,the piston head can be cylindrical with a circular cross section. ln an alternative embodiment,the piston rod can be cylindrical with a circular cross section.
    The operating button 22 is attached to an outer end ofthe piston rod 42 and disposed on theoutside of the wall 20 of the pressure generating section 12, as shown in figure 2. Theoperating button 22 is used to manually move the piston towards the insertion opening andby that eject the suppository. ln this embodiment, the operating button 22 is disc shaped. Thewall 20 of the pressure generating section 12 is provided with an opening (not shown) forreceiving the piston rod 42. The diameter of the operating button 22 is larger than thediameter of the opening in the wall 20. By that the piston can be entered into and removedfrom the pressure generating section 12 through the opening in the wall 20. The outer end ofthe piston rod 42 is provided with a protruding stop element 52 arranged to prevent the piston6 from leaving the body 2. The stop element 52 is neighboring the operating button 22. Thediameter ofthe stop element 52 is larger than the diameter of the opening in the wall 20. Theoperating button 22 and the stop element 52 are arranged on opposite sides of the wall 20.The stop element 52 prevents the piston 6 from sliding out of the body 2.
    The suppository inserter 1 comprises a tubular guiding member 55 for guiding the piston 6during its reciprocal movement. The guiding member 55 is disposed inside the intermediatesection 10 and arranged coaxial with the tubular part 9 of the top section 4. The piston 6 isslidably inserted in the guiding member 55. The guiding member 55 is cylindrically shaped andit extends along the axis of symmetry of the body. The guiding member 55 has a larger innerdiameter d2 than an outer diameter d1 ofthe tubular part 9 so that the second end 32 of thetubular part can be inserted in the guiding member. An upper end of the guiding member isdesigned to receive the second end 32 of the tubular part. ln the following, the function of the suppository inserter 1 will be explained with reference tofigures 2 and 3. As seen from figure 2, at least a part of the piston head 40 is inserted in thetubular part 9 and the cavity 28 is formed between the insertion opening 8 and the pistonhead 40 when the piston 6 is in the withdrawn position. A suppository 57 is inserted into thecavity 28 through the insertion opening 8 so that the suppository bear on the piston head 40,as shown in figure 2. When the suppository is to be ejected, the piston 6 is retracted to itswithdrawn position, and the operating button 22 is manually applied or pushed so that thepiston is moved towards the insertion opening 8. During the movements of the piston 6, thepressure generating section 12 is contracted as shown in figure 3. Due to its elasticity thepressure generating section ofthe body is compressed, which causes the piston to be movingtoward the opening and by that the suppository is ejected. The piston 6 slides forwardthroughout the body 2 until the shoulder 48 of the rear portion 46 of the piston is in contactwith the second end 32 of the tubular part 9 and the piston is in its extended position. Thepiston head 40 slides forward throughout the cavity 28 of the body 2 until it protrudes adistance L3 from the insertion opening 8 of top section 4 when the piston 6 is in the secondextended position. The cylindrical part 50 of the piston guides the movement in the tubularpart 9, and provides a more controlled linear force on the piston 6. The suppository placed inadvance in the insertion opening 8 is ejected into the body cavity of the patient, while theinserter 1 is in its second extended position. The suppository is ejected through the insertionopening 8.
    Figure 7a shows a view of the top section 4 together with the piston 6 in its withdrawnposition. Figure 7b shows a view ofthe top section 4 together with the piston 6 in its extendedposition.
    Figure 8 shows examples of replaceable top sections 4', 4" and 4"' designed for receivingsuppositories of different sizes. The top sections includes covers 5', 5", and 5"' attachable tothe body with attachment means 50. The covers 5'and 5" of the top sections 4' and 4" havedifferent lengths, but the tubular parts 9 of the top sections 4' and 4" have the same length.The inner diameter of the tubular part 9"' of the top section 4"' differs from the innerdiameter of the tubular parts 9 of the top sections 4' and 4". The replaceable top sectionsmake it possible to adapt to different sizes of suppositories. Due to the fact that the cover andthe body is provided with attachment means to removably attach the cover to the body, therecould be designed tubular parts and covers in different sizes depending on the suppositoriessize. The distance between the upper part of the piston head 40 and the first end 30 of thetubular part can be varied depending on the type of suppository by adjusting the length ofthecover while keeping the length ofthe tubular part. Accordingly, the length of the cavity 28 canbe varied to adapt to a certain length of the suppository. The replaceable top sections 4', 4"and 4"' can be used together with one and the same body.
    Figure 9a shows the piston 6 and the top section 4' attached to the body 2 (as shown in figure2). Figure 9b shows the piston 6 and the top section 4" attached to the same body 2. As seenfrom the figures, the distances al, a2 between the upper part of the piston head 40 and the insertion opening 8 differs for top sections 4' and 4” and accordingly the length of the cavity28 differs. Further, the distances bl, b2 between the second end 32 of the tubular part andthe shoulder 48 of the piston differs when different top sections 4', 4" are attached to thesame body. Thus, the distance the piston head 40 is moved differs due to the design of thedifferent top sections 4', 4".
    The present invention is not limited to the embodiments disclosed but may be varied andmodified within the scope of the following claims. For example, the shape of the body mayvary. Other suitable attachment means can be used. The wings of the rear portion of thepiston can, for example, be substituted by a cylindrical part having a larger diameter than thediameter ofthe second end of the tubular part to form a shoulder.
