专利说明:
[0001] Necessary for maintaining and protecting catheters placed on an area of a patient's body. The present invention relates to a kit for maintaining and protecting catheters placed on an area of the body of a patient. A catheter is a medical device used for the prolonged injection into the body of drugs or solutes or for the removal of fluids (such as blood or pus) from the body. The catheter consists of an invasive end composed of a tube of variable width and flexibility, inserted into a vessel or body cavity, and a head or fitting, constituting the non-invasive part of the catheter and allowing connection with a tubing linked to a recovery tank or containing a solute or drug. To avoid infections and get faster healing, it is necessary to change the catheters as little as possible. Thus, rather than removing and reinserting a new hypodermic needle each time a drug is to be administered, it is often more effective and comfortable for the patient to insert a catheter needle which is then left in place on the skin. , sometimes several days and even several months depending on their use. Once placed, the catheter must move as little as possible, this is particularly the case during anesthesia or postoperative analgesia, using perineural catheters. To prevent excessive movement of the needle, the needle is usually attached to the patient. It is known to fix a catheter to use an adhesive tape. Since this solution is not very effective, it is often also necessary to fix the flexible tubes extending from the main body of the catheter with the aid of adhesive strips glued to the patient's skin. Such a method of attachment is however not optimal in that the fixing adhesive elements are detached so that the catheter does not remain firmly attached to the skin of the patient, particularly if it is positioned at a joint . [0002] To solve this problem, it is known to suture the catheter directly to the skin of the patient. Although this solution is safer in terms of fixation, it is obviously not preferred by patients and may lead to other complications such as infections. [0003] Devices for easily removable catheter retention have been developed and are particularly useful where it is necessary to inspect, adjust or replace said catheter. There is thus a large number of documents disclosing devices and methods in which a catheter retaining means is attached to a pad whose lower surface has a self-adhesive coating (protected by a releasable film) through which the pad can be attached to the skin of a patient after insertion of the invasive portion of the catheter into a body cavity; such devices and methods are, for example, described in US-2007 / 0,287,963, US-6,117,163, US-2009 / 0,254,040. [0004] These devices and methods have several disadvantages, for example, they offer an imperfect contact of the self-adhesive face of the pad with the surface of the epidermis, taking into account the reliefs and hollows (fine lines) that this surface presents, which favors the detachment of said cushion which causes uninsured impermeability around the catheter inlet, allowing the passage of water and infectious agents towards the implantation site of said catheter. In addition, these devices generally use rigid plastic elements with prominent profiles that can be uncomfortable and painful for the patient. Finally, a major disadvantage of these devices is that the catheters are too exposed, so they may catch and be torn causing the patient or practitioners to constantly pay attention to their movements, which can be uncomfortable . It has been proposed devices to overcome this disadvantage, including using systems for covering the catheter, so as to avoid contact with external elements may cause its tearing. [0005] For example, US-2008 / 0.065.022 discloses (Figure 3) a catheter fixation device comprising, on the one hand, a pad having an inner surface to be applied to a patient's skin and a surface external, a cavity being formed in the inner surface of said pad for housing the non-invasive part of a catheter, and, secondly, a flexible band or fixing sheet whose central portion is attached to the outer face of the cushion, the protruding end portions of this flexible strip being provided on their inner surface with an adhesive coating intended to be applied to the skin of a patient, after removal of the protective films. [0006] This device also has the same drawbacks as the above-mentioned devices, namely: it does not make it possible to create, around the implantation orifice of the catheter, a tight barrier effectively opposing the passage of water and infectious agents towards the insertion site of the catheter, because the solid surface coated with self-adhesive material of the pad can not closely match the reliefs and hollows (fine lines) of the surface of the epidermis; - It can, for the same reason, easily peel off, unintentionally, with the complications that may arise from a poor positioning of the catheter if we do not quickly remedy this situation. [0007] A disadvantage common to all these devices, results from the fact that their underside is glued during the provision of health care staff so that they do not allow to choose the most appropriate dermal sizing area. This can be troublesome, for example, if the patient has a wound near the location of the catheter. In addition, if a catheter must be kept in place for several weeks or months, the devices are always glued in the same place, they sensitize the skin of the patient, which can create skin traumas or allergic reactions. Another major disadvantage of all these devices is that none of them provides tight catheter protection. [0008] An object of the invention is to overcome the disadvantages of catheter maintenance and protection devices proposed to date. [0009] According to the invention, this object is achieved by means of a catheter holding and protection kit, comprising: on the one hand, a device comprising a pad comprising an inner face and an outer face, said inner face being intended to be applied on the skin of a patient and having a cavity shaped to accommodate the non-invasive portion (head or fitting) of a catheter, while said outer face is attached to the central portion of a thin and flexible cover sheet which comprises a non-bonded projecting peripheral portion extending outwardly from said central portion, and whose inner face is intended to be applied to the skin of the patient, and, on the other hand, a container containing a water-resistant and non-allergenic adhesive gel, this package having an exit orifice shaped to allow the application of a bead of adhesive gel to the skin, around the location the non-invasive part (head or fitting) of the catheter after insertion of the catheter. [0010] With this kit, the application of the protruding peripheral part of the cover sheet on the adhesive gel cord, allows for an intimate and tight connection between the skin and said cover sheet, thus constituting an effective means s' opposing any movement of the catheter. The device for holding and protecting catheters according to the invention provides several advantageous advantages, in particular: to allow a solid fixation of the catheters. Indeed, the deposition of a continuous bead of adhesive between the skin and the protective sheet allows an effective fixation thereof. This continuous cord placed in direct connection between the skin and the sheet makes it possible to guarantee total peripheral fixation, without any problem of continuity; to allow a leakproof protection of the catheters. Indeed, the deposition of a continuous bead of adhesive between the skin and the protective sheet also ensures a perfectly tight barrier function. This continuous barrier placed in direct connection between the skin and the sheet ensures excellent sealing, thus ensuring a guarantee against the risk of contamination or contamination of the protected parts, by contact with impure elements, including with polluted liquids; - To allow the realization of a "tailor-made" protection of catheters whose location is generally very varied, by the choice of sizing adapted to each situation; - allow easy access for the inspection of the catheter or replacement of the device, not requiring the systematic removal of the catheter; - to be easy and fast to use; - to be also very economical. According to an important characteristic arrangement, the adhesive has lower skin adhesion properties than its adhesion properties to the cover sheet, so as to allow removal of the device without painful effect or adhesive residue on the skin. skin. According to a preferred embodiment, the pad has a generally flat shape. According to one embodiment, the device comprises a detachable protective sheet applied against the outer face of the cover sheet, this protective sheet having a lower flexibility than that of said cover sheet. According to an exemplary embodiment, the cover sheet has dimensions allowing its cutting, this overall sheet is preferably carried out in a non-allergenic material and easily divisible into smaller pieces or fractions, for example by means of a pair of scissors. According to an exemplary embodiment, the cover sheet is made of polyurethane or polyurethane-based polymer. According to an exemplary embodiment, the cover sheet has a thickness of between 2 micrometers and 3 millimeters, and preferably a thickness of between 10 micrometers and 80 micrometers. According to one embodiment, the pad is made of any material having the robustness and flexibility necessary for good maintenance of the catheter and a good comfort for the patient such as viscose, silicone, polypropylene, sodium polyacrylate, cellulose. [0011] According to an exemplary embodiment, the adhesive consists of a copolymer, preferably based on silicone, for example by a glue based on polydimethylsiloxane, with functional groups, or based on polyacrylate or acrylic-based. The foregoing and other objects, features and advantages will become more apparent from the following description and the accompanying drawings, in which: FIG. 1 is a perspective view of the elements constituting the kit or required according to the invention. Figure 2 is a top view of the holding device. Figure 3 is a bottom view thereof. [0012] FIG. 4 is a sectional view on a larger scale taken along line 4-4 of FIG. 2. FIG. 5 is a perspective view showing a catheter inserted into a blood vessel of the forearm of a person and placing a self-adhesive gel bead around the non-invasive part of the catheter. [0013] Figure 6 is a sectional view on a larger scale showing the device for fixing and holding the catheter on the forearm of a person. Referring to said drawings to describe an interesting example, although not limiting, of realization of the necessary protection and maintenance of catheters, according to the invention. [0014] The kit for protecting and holding catheters according to the invention essentially comprises: a device 1 consisting of a thin and flexible cover sheet 2 whose central portion 2a is attached to a pad 3 shaped to house the non-invasive part ( head or connection) of a catheter C placed on an area of the body of a patient, and whose protruding peripheral portion which extends outwardly from said central portion 2a, also called peripheral peripheral edge 2b, is unsized; and a package 4 containing an adhesive gel 5. The cover sheet 2 can be made of any thin and flexible material and, preferably, a non-allergenic material, for example polyurethane or polyurethane-based polymer, waterproof with water and bacteria, and easily cut by means of a manual instrument such as a pair of scissors. It has dimensions allowing the cutting around the pad 3 appropriate to the shape and location of the catheters. For example, it may have a length less than 20 cm and a width greater than 4 cm. It can be transparent, translucent, opaque, white or tinted, even decorated with various patterns. Advantageously, the device 1 further comprises a detachable protective sheet (not shown) applied against the outer face of the cover sheet 2, this protective sheet having a lower flexibility than that of said cover sheet. The inner face (face on which is the pad 3) of the peripheral edge 2b of the cover sheet 2 is intended to be applied to the skin P of the patient via a bead of adhesive gel. On the other hand, it advantageously has a thickness of between 2 μm and 3 mm, and preferably a thickness of between 10 μm and 80 μm. The pad 3 has an inner face 3a and an outer face 3b, said inner face being intended to be applied to the skin P of a patient and having a cavity 3c shaped to accommodate the non-invasive part (head or fitting) of a catheter C, while said outer face is attached to the central portion 2a of the cover sheet 2, by any suitable means known per se, for example by means of a biocompatible glue. Preferably, the pad 3 has a generally flat shape. The pad is made of any material that has the sturdiness and flexibility necessary for proper C catheter retention and patient comfort. For example, it is made of viscose, silicone, polypropylene, sodium polyacrylate, cellulose, ... The adhesive container 4 can be constituted by a compressible tube containing an adhesive of pasty consistency 5. Of course, any other type of container would be usable. The container 4 preferably comprises an extrusion head or a neck 4a - shaped, in a manner known per se, to allow the distribution of the adhesive 5 contained in said container in the form of a flexible bead 5a. Adhesive 5 is also non-allergenic and biocompatible. It may advantageously consist of a copolymer, preferably based on silicone, for example by a glue based on polydimethylsiloxane, with functional groups, or based on polyacrylate or acrylic-based. The adhesive 5 contained in the container 4 is waterproof and has properties that allow it to adhere to both the patient's skin P and the cover sheet 2, without being previously adhered to the one or other of the two surfaces. [0015] Preferably and advantageously, the adhesive 5 has properties of adhesion to the skin P of the patient less than its adhesion properties to the cover sheet 2, so as to allow the removal of the device 1 without pain or residue adhesive on the skin. The adhesive 5 and the cover sheet 2 have properties that make them perfectly compatible elements in adhesion to be able to adhere to each other in a situation and to meet the constraints. In other words, the adhesive 5 and the cover sheet 2 are made of materials chosen for their properties so that they can adhere to one another so as to provide the necessary seal. According to the mode of implementation of the maintenance and protection kit according to the invention, the catheter is inserted into a lumen of a cavity of the body or blood vessel of a patient, at the desired location according to its use; a bead 5a of flexible waterproof and non-allergenic adhesive, and further having properties allowing it to adhere to both the skin and the protective sheet, is deposited on the most appropriate area of the skin P of the patient, around the location of the non-invasive part (head or connection) of the catheter C to protect and maintain, the adhesive gel 5 rushes into the wrinkles of the skin thereby providing a barrier against the risks contamination or contamination by contact with impure elements, including polluted liquids. The holding device 1 is then placed on the patient on the cover of the catheter, so, on the one hand, to match the cavity 3c housing of the catheter C with the non-invasive part of said catheter C thus achieving an intimate retention of the latter and, on the other hand, that the protruding peripheral edge 2b of the thin, flexible, watertight and unsized, cover sheet 2, preferably made of a non-allergenic material, comes to apply. on the peripheral adhesive bead 5a, thereby providing an intimate connection between the skin and the individual cover sheet 2 and the tight isolation of the catheter C, thus providing an intimate and tight connection between the skin P and said cover sheet 2, constituting an effective means opposing any movement of the catheter C. The edge portion 2b extending beyond the adhesive gel peripheral bead 5a with respect to the catheter C can be cut out to the desired size and shape, depending on the size, shape and location of catheter C. [0016] The protection and holding device according to the invention thus applied to the skin of a patient can remain in place for several days. When the device 1 is to be replaced, for example for the inspection of the catheter, the cover sheet is removed by pulling on the latter. Since the bonding torque between the adhesive 5 and the skin P of the patient is less than the bonding torque between the adhesive 5 and the cover sheet 2, the device 1 can be removed without pain or any traumatic effect for the patient, and without leaving adhesive residue on the skin of the latter. During the installation of a new device 1, a new bead 5a of adhesive gel 5 is deposited on the most appropriate fa area of the patient's skin P, around the location of the non-invasive part (head or connection) of the patient. catheter C, but slightly varying the sizing area with respect to the previous sizing area. The sizing zones can thus be alternated with each replacement of the device 1 in order to avoid allergic risks or possible skin traumas that could occur by placing the adhesive gel too long on the same skin surface.
