专利说明:

[1] [0001] This invention generally relates to a pneumatic connector device to connect apneumatic circuit tube to a pair of end fittings of a pneumatic system, and moreparticularly to a pneumatic connector device to disconnect a dual pneumatic tubesconnecting a patient interface via a breathing circuit tube to a pneumatic system such as a ventilator or respirator or the like.BACKGROUND
[2] [0002] Medical equipment typically includes various types of hoses and tubes fortransmitting gases. For example, anesthesia and respiratory care typically usespneumatic circuit tubes to supply oxygen and/or anesthesia from the ventilatingapparatus (machine) to a patient (e.g., mask). The tubes can typically include aninspiratory tube and an expiratory tube for positive connection to the pneumatic system.Each tube is known to positively attach to the ventilating machine via utilizing male andfemale taper adapters, controlled by industry standards. Typically the female adaptersinclude a taper for positive connection to a taper at the male adapters at the pneumaticsystem. Typical female and male adapters also are known to have a groove at the rear of each taper.
[3] [0003] Drawbacks of known connections of the tubes to the pneumatic systeminclude increased likelihood of disconnection if the taper at the female adapter of thetube is not fitted tightly to the taper at the male adapter at the pneumatic system, whichis dependent on the force used to push the female and male adapter tapers together. ADisconnection can disrupt the supply of breathing air, anesthesia or other gases to thepatient or other desired manner. Another known drawback of pneumatic system is thecumbersome multiple connections of tubes to be made at the pneumatic system. Thehoses or tubes may need to be routinely connected and disconnected for cleaning and/or disposal.
[4] [0004] The above-mentioned shortcomings, disadvantages and problems areaddressed by the embodiments described herein in the following description of amethod and device to attach multiple medical hoses to a medical machine. In oneexample, an advantage of the dual connector apparatus provides for a need for readyconnection of the circuit tubes between the patient and a ventilating apparatus.Operators desire a dual connector apparatus to be inexpensive, compatible with industrystandards, and provide a reliable positive connection and ready disconnection of the hoses or tubes for cleaning or disposal.
[5] [0005] In one embodiment of the subject matter described herein, a connector deviceto attach a pneumatic circuit tube to a first and second end fitting of a pneumatic systemis provided. The device comprises a first connecting structure that positively attaches topneumatic circuit tube to the first end fitting of the pneumatic system, and a secondconnecting structure that positively attaches to the pneumatic circuit tube to the secondend fitting of the pneumatic system. A pull arm connects between the first connectingstructure to the second connecting structure, and transmits a single application of forceon the pull arm to release both the first connecting structure from attachment at the firstend fitting and the second connecting structure from attachment at the second end fitting.
[6] [0006] In another embodiment of the subject matter described herein, a connectordevice to connect a pneumatic circuit tube between a patient interface and a pneumaticsystem is provided. The device comprises a manifold including a first tube and secondtube that interconnects the pneumatic circuit tube to the first and second end fittings ofthe pneumatic system, and a dual connector apparatus that includes a first connectingstructure and a second connecting structure. The first connecting structure positivelyattaches the first tube at the first end fitting of the pneumatic system and the secondconnecting structure positively attaches the second tube at the second end fitting. Thedual connector further includes a pull arm that interconnects the first and second connecting structures, such that an application of force on the pull arm causes both release of the first and second connecting structures from positive attachment at the first and second end fittings of the pneumatic system.

Each pneumatic system end fitting 145, 150 caninclude a reduced diameter portion 155 extending outward from the machine 105, andan enlarged diameter portion 160 extending further outward from the reduced diameterportion 155, defining a shoulder 165 (See Fig. 2) therebetween Where the reduced andenlarged diameter portions 155, 160, respectfully abut one another. An embodiment ofeach pneumatic system end fitting 145, 150 can be a male type according to an industrystandard configured to receive the pneumatic connector device 100, and each end fitting145, 150 can be staggered in alignment relative to one another in extending from the pneumatic system 105.
[18] [0018] The first and second branch tubes 125, 130 of the manifold 120 can eachinclude an end fitting 170, 175 that is a female type according to an industry standard,one of which includes a 22m rubber or plastic connecting structure, configured toreceive the respective male type end fitting of the pneumatic system 105. The endñttings 170, 175 of the first and second branch tubes 125, 130 of the manifold 120 canfurther include a circular or annular groove 180, 185 (See Fig. 3) or recess of standard dimensions.
[19] [0019] An embodiment of the pneumatic connector device 100 can further include adual connector apparatus 190 (illustrated in cross-hatching in Figs. l and 2) generallyconfigured to connect and provide for ready disconnection or removal of the expiratoryand inspiratory branch tubes 125, 130 from the end fittings 145, 150 at the pneumaticsystem 105. One embodiment of the dual connector apparatus 190 can be a unitary,plastic injection molded part (e.g., polysulfone) that is steam autoclavable or single-use(e.g., nylon) and capable to being displaced With material memory or bias to return to the original position. The dual connector apparatus 190 can be capable of being removed independent of the manifold 120, or removed in combination With themanifold 120.
[20] [0020] Referring to Figs. 2 and 3, the dual connector apparatus 190 can includes afirst connecting structure 195 opposite from a second connecting structure 200, With apull arm 205 interconnected therebetween. The first connecting structure 195 can beconfigured to positively attach the end fitting 170 of the first expiratory branch tube 125of the manifold 120 of the pneumatic connector device 100 to the respective expiratoryend fitting 145 of the pneumatic system 105. In a like manner, the second connectingstructure 200 can be configured to positively attach the end fitting 175 of the inspiratorybranch tube 130 of the manifold 120 of the pneumatic connector device 100 to the respective inspiratory end fitting 150 of the pneumatic system 105.
[21] [0021] Each first and second connecting structure 195, 200 of the dual connectorapparatus 190 can include an annular ring 210, 215 of similar dimension to the annulargrooves 180, 185 of the end fittings 170, 175 of the first and second branch tubes 125,130 of the pneumatic connector device 100. The annular rings 210, 215 can be capableof being slid onto and advanced over a tapered construction at the end fittings 170, 175of the branch tubes 125, 130 until the annular rings firmly slip into or snap into properpositive attachment in the annular grooves 180, 185 of the end fittings 170, 175 of themanifold 120 of the pneumatic connector device 100. Once the annular rings 210, 215of the connecting structures 195, 200 positively attach into the annular grooves 180, 185of the end fittings 170, 17 5 of the manifold 120, the dual connector 190 can bepositively locked to the end fittings 170, 175 of the manifold 120 and attached breathingcircuit tube 110 leading to the patient interface 115, and cannot be removed Without substantial force.
[22] [0022] Each connecting structure 195, 200 of the dual connector apparatus 190 canfurther include a flexible j aW or latch 225, 230 configured to positively attach at therespective end fitting 145, 150 of the pneumatic system 105. Each flexible latch 225,230 can include a semi-annular catch or step 245 (See Fig. 3) to engage against the reduced diameter portion 155 or shoulder 160 of the end fittings 145, 150. An embodiment of the first and second latches 225, 230 can each include a step orprotrusion 245 that engages against the reduced diameter portion 155 or shoulder 160 ofthe end fittings 145, 150 of the pneumatic system 105.
[23] [0023] An embodiment of the latches 225, 230 of the first and second connectingstructures 195, 200 can be connected by pairs of first and second flexible bridge tabs235, 240 (See Fig. 2) to the annular rings 210, 215. An embodiment of the firstconnecting structure 195 includes a first pair of bridge tabs 235 that interconnect thefirst latch 225 to the first annular ring 210. In a similar manner, the second connectingstructure 200 includes a second pair of bridge tabs 240 that interconnects the secondlatch 230 to the second annular ring 215. Each first and second pair of bridge tabs 235define a gap 250 (See Fig. 2) therebetween, such that the first pair of bridge tabs 235separate the first latch 225 from the first annular ring 210, and the second pair of bridgetabs 240 separate the second latch 230 from the second annular ring 215. The numberof bridge tabs 235, 240 can Vary. The pairs of bridge tabs 235, 240 can interconnectbetween an edge 260 of the first and second latches 225, 230 (opposite the step orprotrusion 245) and the annular rings 210, 215 respectively.
[24] [0024] An embodiment of the pull arm 205 can include a first end that connects atthe edge 260 of the first latch 225, and a second end that interconnect to the secondlatch 230 in a similar manner, both opposite the step or protrusion 245. A substantiallength of the pull arm 205 between the first and second ends can be substantially linearaligned along its length. The pull arm 205 can also include an actuator handle 265.The illustrated example of the actuator handle 265 can be ring-shaped of standarddimension to receive a operator finger, and located along the substantial linear length ofthe pull arm 205. Yet the shape of the actuator handle 265 can vary. The length of thepull arm 205 can be of standard dimension according to the space between theexpiratory branch tube 125 relative to the inspiratory branch tube 130 of the manifold120 to receive the end fittings 145, 150 at the pneumatic system 105.
[25] [0025] Having described the general construction of the pneumatic connector device 100 having the dual connector apparatus 190, the following is a general description of the operation of the pneumatic connector device 100 in positively attaching the pair ofend fittings 170, 175 of the pneumatic connector manifold 120 to the end fittings 145,150 at the pneumatic system 105. It should be understood that the following descriptionof the operation of the pneumatic connector device 100 may include more steps or less steps and may not be all-inclusive.
[26] [0026] Assume for sake of example that the annular rings 210, 215 of the dualconnector apparatus 190 of the pneumatic connector device 100 are both positivelyengaged thereby locked in the annular grooves 180, 185 in the expiratory andinspiratory end fittings 170, 175 of the manifold 120, as described above. Bothexpiratory and inspiratory branch tubes 125, 130 of the manifold 120 are ready topositively attach via the dual connector apparatus 190 to the end fittings 145, 150 of the pneumatic system 105.
[27] [0027] An embodiment of the dual connector 190 can be operatively configured togenerally simultaneously attach the end fittings 170, 175 expiratory and inspiratorybranch tubes 125, 130 of the pneumatic manifold 120 to the respective end fittings 145,150 of the pneumatic system 105. With pressure applied to advance the female typeend fittings 170, 175 of the manifold 120 over the respective male type end fittings 145,150 of the pneumatic system 105, each latch 225, 230 can be configured to angularly deflect or displace away relative to the angular rings 210, 215.
[28] [0028] As the annular latches 225, 230 advance beyond the enlarged diameterportion 160 and over the reduced diameter portion 155 of the end fittings 145, 150, theannular latches 225, 230 deflects or displaces under material memory bias intoengagement against the reduced diameter portion 155 or the shoulder 165 definedbetween the reduced and enlarged diameter portions 155, 160, respectively. Accordingto one embodiment, an audible click can be heard when the annular latches 225, 230snaps into engagement with the reduced diameter portion 155 or shoulder 165, the clickgiving affirmation of the proper attachment of the pneumatic connector device 100 tothe end fittings 145, 150 of the pneumatic system 105. The engagement of the annularlatches 225, 230 of the dual connector apparatus 190 against the shoulder 165 of the end fittings 145, 150 can positively attach or lock the end fittings 170, 175 of the manifold120 of the pneumatic connector device 100 in proper attachment to the end fittings 145, 150 at the pneumatic system 105.
[29] [0029] The dual connector apparatus 190 can also provide for ready and generallysimultaneous detachment or removal of both end fittings 170, 175 of the manifold 120of the pneumatic connector device 100 from the end fittings 145, 150 at the pneumaticsystem 105 With a same, single application force (illustrated by arrow and reference270) at the pull arm 205 of the dual connector apparatus 190. The single application offorce 270 at the actuator handle 265 of the pull arm 205 can bias both annular latches195, 200 from engagement against the reduced diameter portion 155 of the end fittings145, 150. The pull arm 205 can be operable to generally transmit the application forceamongst the pairs of tab bridges 235, 240 at the connecting structures 195, 200, causinga bending moment or bias about the pairs of bridge tabs 235, 240 to deflect or displaceor both annular latches 225, 230 away from engagement against the end fittings 145,150 at the pneumatic system 105. The dual connector apparatus 190 can transmit theapplication force as a generally inWard bending moment force to both connectingstructures 195, 200 to cause angular displacement or deflection With respect to theannular rings 210, 215 in a generally simultaneous manner, releasing both annularlatches 225, 230 in a generally simultaneous manner from engagement against the reduced diameter portion 155 or shoulder 165 of the end fittings 145, 150.
[30] [0030] With release of engagement of the annular latches 225, 230, the dualconnector apparatus 190 and connected manifold 120 of the pneumatic connectordevice 100 are released in a generally simultaneous manner from positive attachment tothe end fittings 145, 150 of the pneumatic system 105. To cause this generallysimultaneous release of the both end fittings 170, 175 of the manifold 120 from positiveattachment to the end fittings 145, 150, the actuator handle 265 can be generallyoperable to transmit the application force 270 to create the bending moment to deflectboth annular latches 225, 230 in the general simultaneous manner from engagementagainst end fittings 145, 150 so as to release the pneumatic connector device 100 from the end fittings 145, 150. Of course, actuator handle 265 can be a general bend (e.g., curve, etc. or other shape) to guide location to apply the application force 270 to thedual connector apparatus 190, and its shape is not limiting. Furthermore, although thedual connector apparatus 190 can be described to include the actuator handle 265, theactuator handle 265 may not be included, and an operator can apply the application atany point along the pull arrn 205 to generally cause the bias force to deflect bothannular latches 225, 230 from engagement against the end fittings 145, 150 in asufficient manner to operate the dual connector apparatus 190 in releasing the manifold120 of the pneumatic connector device 100 from the end fittings 145, 150 of the pneumatic system 105.
[31] [0031] Fig. 4 shows another embodiment of a pneumatic connector device 400configured to connect to pneumatic system 405 to a single pneumatic circuit tube orhose 410, the pneumatic system 405 and pneumatic circuit tube 410 of similarconstruction to the pneumatic system 105 and pneumatic circuit tube 110 describedabove. The pneumatic connector device 400 can include a manifold 420 having a firstbranch tube 425 and an second branch tube 430 integrally constructed as part of a dualconnector apparatus 435. An example of the first branch tube 425 can be associatedWith transmitting expiratory fluids With the pneumatic circuit tube 410 leading to apatient interface 440, and the second branch tube 430 can be associated Withtransmitting inspiratory fluids With the pneumatic circuit tube 410 leading to the patientinterface 440. Each expiratory and inspiratory branch tubes 425, 430 of the manifold420 can include a female type connecting structures 445, 450 (similar to the connectingstructures 170, 175) to receive the male type end fittings 455, 460 of the pneumaticsystem 405. A pull arrn 470 generally extends between and connects to a deflectablelatches 475, 480 located at each opposite connecting structures 445, 450 of thepneumatic connector device 400. The exemplary pull arrn 470 is curvilinear shaped,but the shape (e. g., linear, angular, etc.) can vary. Each latch 475, 480 can beconfigured to engage against the end fittings 455, 460 in a similar fashion as describedabove With respect to the above-described embodiment of the pneumatic connectordevice 100. In a like a manner, an application force 485 can be applied along the lengthof the pull arm 470 can create a bending moment or bias force about a first and second pairs of bridge tabs 495 attached at the manifold 420, so to cause each first and second _10- latch 475, 480 to deflect away from and release engagement With the end fittings 455,460 of the pneumatic system 405 so as to release the pneumatic connector device 400and attached pneumatic circuit tube 410 from attachment at the end fittings 455, 460 of the pneumatic system 405.
[32] [0032] Although the above description of the embodiments of the pneumaticconnector devices 100 and 400 are described With reference to attachment of apneumatic circuit tube between a patient interface and a pneumatic system, the device100 and method of operation may not so limited. The device 100 and method ofoperation can be employed in other applications of attaching medical hoses to medicalmachines, and fiarthermore can be applied to other industrial applications to connect hoses to a machine.
[33] [0033] A technical effect of the embodiments of the pneumatic connector device100, 400 described herein includes provides for attachment of multiple medical hoses toa medical machine (e. g., pneumatic or ventilation system). In one example, anadvantage of the pneumatic connector device 100, 400 and dual connector 190 providesfor a need for ready connection and disconnection of the pneumatic circuit tube 110,410 between the patient interface 115, 440 and the pneumatic system 105, 405. Thepneumatic connector device 100, 400 can be inexpensive, compatible With industrystandards, and provide a reliable positive connection and ready disconnection ofmedical devices, tubes or hoses (e. g., manifold 120, 420 and pneumatic circuit tube 110,410 and interface 115, 440) for cleaning or disposal. The pneumatic connector device100, 400 can prevent unintended or undesired misconnections because the connectingStructures can be located at a fixed distance in accordance to industry standards to receive the end fittings at the pneumatic system 105, 405.
[34] [0034] In another example of a technical effect, the pneumatic connector device 100,400 can prevent a force (Whether intentional or unintentional such as tripping overcircuit tube 110, 420) exerted at the pneumatic circuit tube 110, 410 or interface 1 15,440 from causing disconnection of the pneumatic circuit tube 110 from connection at the pneumatic system 105. The pneumatic connector device 100, 400 can prevent _11- disconnections because retention of the pneumatic circuit tube 110, 410 at thepneumatic system 105, 405 can be provided With a positive interference of the latches225, 230, 475, 480 at the end fittings 145, 150, 455, 460 rather than sliding interferencebetween the expiratory and inspiratory tube end fittings 170, 175 or connectingstructures 445, 450 in relation to the end fittings 145, 150, 455, 460 of the pneumaticsystem 105, 405. The pneumatic connector device 100, 400 also provides operatorfeedback by generating an audible click With proper positive attachment of the latches225, 230, 475, 480 of the pneumatic connector devices 100, 400 to the end fittings 145,150, 455, 460 of the pneumatic systems 105, 405. An application of force at multiplepoints or discrete areas along the length of the pull arm 205, 470 of the connectordevices 100, 400 can cause release of the latches 225, 230, 475, 480 and disconnectionfrom the pneumatic system 105, 405, but the connector devices 100, 400 can otherwiseprevent disconnection if the application of force is exerted on the manifold 120, 420,pneumatic tube or hose 110, 410 or at the interface 115, 440. An application of force atmultiple discrete areas (e. g., manifold, 420 or branch tubes 425, 430) of the connectordevice 400 can cause general simultaneous connection of the both end connectingstructures 175, 180, 445, 450; latches 225, 230, 475, 480; and attached pneumaticcircuit tube 110, 410 and interface 115, 440 to the end fittings 455, 460 of the pneumatic system 405.
[35] [0035] It should be understood that one or more constructive aspects or features(e.g., connecting structure 195, 200, manifolds 120, latches 225, 230, pull arm 205, etc.)described above for the illustrated embodiments of the connector device 100 can beincorporated on the illustrated embodiments of the connector device 400, and vice versa, and is not limiting on the subject matter described herein.
