Description

Technical Field

[0001] This invention belongs to the field of medical devices, and particularly relates to a housing for mounting a breathing circuit module, a breathing circuit module assembly, and a medical device. Background Technology

[0002] For major surgeries, general anesthesia is often required, and inhalation anesthesia is a commonly used method. During anesthesia, the gas outlet of the inhalation anesthesia machine forms a circuit with the patient's airway, delivering fresh gas and inhaled anesthetic drugs into the patient's airway and expelling the patient's exhaled air.

[0003] In existing respiratory anesthesia machines, the various gas pathway modules are set up separately, which is inconvenient to use. Therefore, a respiratory anesthesia machine that integrates the various gas pathway modules into a single module has been developed. In order to protect the gas pathway module as a whole, an outer shell has been set up to protect the entire gas pathway module.

[0004] Specifically, the breathing circuit module is installed inside the housing, which protects the module from direct liquid spillage that could damage it. One port of the breathing circuit delivers gas to the patient, while the other port receives exhaled gas. If a patient has a respiratory illness, the breathing circuit module needs to be sterilized at high temperatures to prevent transmission to the next patient. Since sterilization is required after each patient's use, it is inconvenient to sterilize the module enclosed in the housing. Therefore, there is a pressing need for an easily removable housing to address this issue. Summary of the Invention

[0005] This invention provides a housing for installing a breathing circuit module, aiming to solve the problem that in existing respiratory anesthesia machines, the breathing circuit module enclosed in the housing is inconvenient to disinfect.

[0006] In a first aspect, the present invention provides a housing for mounting a breathing circuit module, the housing comprising:

[0007] The upper housing has a first slot on one side wall and a second slot on the side wall adjacent to the first slot.

[0008] Lower casing; and

[0009] The disassembly and assembly mechanism includes:

[0010] A rotating component is rotatably mounted on one end of the lower housing, and the rotating component is provided with a first buckle that is adapted to the first slot;

[0011] A sliding rod is mounted on the lower housing. The sliding rod is provided with a second buckle that is adapted to the second slot. One end of the sliding rod abuts against one end of the rotating member. The sliding rod can slide relative to the lower housing from a first position to a second position.

[0012] When the rotating component rotates relative to the lower housing, it causes the first buckle to disengage from the first slot and drives the slide rod to move so that the second buckle disengages from the second slot.

[0013] A reset element is connected to the slide bar and is used to reset the slide bar from the second position to the first position.

[0014] Optionally, the slide bar is provided with a plurality of second latches at intervals.

[0015] Optionally, the disassembly and assembly mechanism further includes a fixing member disposed above the slide bar and fixedly connected to the lower housing.

[0016] Optionally, the fastener has a first through hole through which the second buckle passes.

[0017] Optionally, the second buckle is provided with a first limiting part for restricting the movement of one end of the reset member, and the fixing member is provided with a second limiting part for restricting the movement of the other end of the reset member.

[0018] Optionally, a slide rail is provided inside the lower housing, and the slide rod is installed on the slide rail and can slide along the slide rail. Multiple protrusions are provided on the side of the slide rod that contacts the fixing member and the side that contacts the bottom of the slide rail.

[0019] Optionally, the end of the slide rod that abuts against the rotating member is provided as an arc surface.

[0020] Optionally, the rotating member includes:

[0021] The rotating part has a mounting groove on the lower housing for mounting the rotating part. The rotating part is rotatably connected to the mounting groove. The first buckle is located on one side of the rotating part. The side wall of the mounting groove has a second through hole for the first buckle to pass through. The other side of the rotating part has a pull part protruding from the mounting groove.

[0022] The pushing part is fixed to the side of the rotating part where the first buckle is provided, and is located at the end of the rotating part near the slide rod.

[0023] Optionally, there may be multiple first buckles, and the number of second through holes may be the same as the number of first buckles.

[0024] Optionally, the lower housing has a third slot at the other end opposite to the first buckle, and the upper housing has a third buckle that cooperates with the third slot.

[0025] Secondly, the present invention provides a breathing circuit module assembly, the breathing circuit module assembly including a breathing circuit module and the aforementioned housing, wherein the breathing circuit module is installed inside the housing.

[0026] Thirdly, the present invention provides a medical device including the above-mentioned breathing circuit module assembly.

[0027] The beneficial effects achieved by this invention are as follows:

[0028] The housing provided by this invention is used to install a breathing circuit module. A disassembly and assembly mechanism enables the installation and disassembly of the upper and lower housings, facilitating the separation of the upper and lower housings after each use of respiratory anesthetics for disinfection of the breathing circuit module and the housing itself. During disassembly, flipping up the rotating component disengages the first latch from the first slot, simultaneously driving the sliding rod to disengage the second latch from the second slot. Only one operation is required to completely separate the upper and lower housings, making the process simple, convenient, and quick. A reset component ensures that the sliding rod automatically returns to its first position after disassembly, meaning that when the upper and lower housings are reassembled, the first latch and first slot, as well as the second latch and second slot, automatically re-engage, resulting in high reuse efficiency.

[0047] Because the breathing circuit module is relatively large, its outer casing is also quite large. Using screws, pins, or other disassembly / reassembly structures would be inconvenient for installation and fixation. The outer casing provided by this invention is used to install the breathing circuit module. A disassembly / reassembly mechanism enables the installation and disassembly of the upper and lower casings, facilitating the separation of the upper and lower casings after each use of respiratory anesthetics for disinfection of the breathing circuit module and the casing itself. During disassembly, flipping up the rotating component disengages the first latch from the first slot, simultaneously driving the sliding rod to disengage the second latch from the second slot. Only one operation is required to completely separate the upper and lower casings, making the process simple, convenient, and quick. A reset component ensures that the sliding rod automatically returns to its first position after disassembly. This means that when the upper and lower casings are reassembled, the first latch and first slot, as well as the second latch and second slot, automatically re-engage, resulting in high reuse efficiency.

[0048] Example 1

[0049] Please see Figures 1 to 8 This embodiment provides a housing for mounting a breathing circuit module, the housing comprising:

[0050] The upper housing 100 has a first slot 110 on one side wall and a second slot 120 on the side wall adjacent to the first slot 110.

[0051] Lower housing 200; and

[0052] The disassembly and assembly mechanism includes:

[0053] Rotating component 310 is rotatably mounted on one end of the lower housing 200. The rotating component 310 is provided with a first buckle 340 that is adapted to the first slot 110.

[0054] The slide rod 320 is mounted on the lower housing 200. The slide rod 320 is provided with a second buckle 350 that is adapted to the second slot 120. One end of the slide rod 320 abuts against one end of the rotating member 310. When the rotating member 310 rotates, it drives the slide rod 320 to slide relative to the lower housing 200 from the first position to the second position.

[0055] When the rotating component 310 rotates relative to the lower housing 200, it causes the first latch 340 to disengage from the first slot 110, and drives the slide rod 320 to move so that the second latch 350 disengages from the second slot 120;

[0056] The reset member 330 is connected to the slide bar 320 and is used to reset the slide bar 320 from the second position to the first position.

[0057] In this embodiment, when the upper shell 100 and the lower shell 200 are fastened together, the overall outer shell formed by the two presents a cuboid-like shape. The upper shell 100 includes a bottom surface of the cuboid and a side wall formed by a short side extending from one end of the bottom surface in a direction substantially perpendicular to the bottom surface. This side wall is provided with a first slot 110. Similarly, a long side adjacent to the aforementioned short side on the bottom surface extends in a direction substantially perpendicular to the bottom surface to form another side wall, which is provided with a second slot 120. It is understood that in the upper shell 100, the aforementioned bottom surface and the two side walls are in a mutually perpendicular positional relationship.

[0058] Correspondingly, the lower housing 200 includes another bottom surface opposite to the aforementioned bottom surface in a cuboid, two long sides of the aforementioned bottom surface extending in a direction substantially perpendicular to the bottom surface to form side walls, and another short side opposite to the aforementioned short side extending in a direction substantially perpendicular to the bottom surface to form a side wall. When the upper housing 100 and the lower housing 200 are engaged, a slide rail is provided on one of the side walls of the lower housing 200 that is on the same plane as the side wall of the upper housing 100 with the second slot 120. This slide rail is arranged along the length of the side wall, and the slide rod 320 slides along the slide rail. Furthermore, the three adjacent side walls of the lower housing 200 are smoothly connected by an arc surface.

[0059] The upper housing 100 and the lower housing 200 are assembled and disassembled through a disassembly and assembly mechanism. The disassembly and assembly mechanism includes a rotating component 310, a sliding rod 320, and a reset component 330. The rotating component 310 is located at the end of the lower housing 200 where there is no side wall. The number of first buckles 340 on the rotating component 310 can be set according to actual usage needs; one or more can be set.

[0060] In this embodiment, taking three first buckles 340 arranged at approximately equal distances as an example, correspondingly, three first slots 110 on the upper housing 100 are also arranged at equal distances. In the initial state, that is, when no external force is applied to the rotating member 310, the first buckles 340 and the first slots 110 are in the engaged position. When an external force is applied to cause the rotating member 310 to rotate relative to the lower housing 200, the first buckles 340 and the first slots 110 are disengaged.

[0061] One end of the slide rod 320 abuts against one end of the rotating member 310. When no external force is applied to the rotating member 310, the slide rod 320 is in the first position, such as... Figure 7 As shown, at this time, the second slot 120 and the second buckle 350 are engaged. When an external force is applied to cause the rotating part 310 to rotate relative to the lower housing 200, the slide rod 320 can slide to the second position within the slide rail along the length of the lower housing 200, as shown. Figure 8 As shown, at this time, the second card slot 120 and the second buckle 350 are disengaged.

[0062] The reset member 330 is used to reset the slide bar 320 from the second position to the first position when the external force applied to the rotating member 310 disappears. That is, it resets the second slot 120 and the second buckle 350 from the disengaged state to the engaged state. The reset member 330 can be an elastic element such as a tension spring, a spring, or rubber. The specific installation position of the reset member 330 can be adjusted according to the actual application of the reset member 330. In this embodiment, the reset member 330 is a tension spring.

[0063] In this embodiment, the working principle of the outer shell is as follows: Taking the initial state when the upper shell 100 and the lower shell 200 are assembled as an example, at this time, no external force is applied to the rotating part 310, the first slot 110 and the first buckle 340 and the second slot 120 and the second buckle 350 are all in the engagement state, and the breathing circuit module is encapsulated in its internal space.

[0064] When disassembly is required, an external force is applied to the rotating component 310 to make it rotate. First, the first slot 110 is disengaged from the first buckle 340. At the same time, the rotating component 310 drives the slide bar 320 to slide from the first position to the second position, so that the second slot 120 is disengaged from the second buckle 350. At this time, the connection between the upper housing 100 and the lower housing 200 is completely released, and the two can be disassembled and separated. The reset component 330 resets the slide bar 320 from the second position to the first position.

[0065] When reassembly is required, the second latch 350 gradually enters the second slot 120. During the entry process, the slide rod 320 slightly moves away from the first position and slides a certain distance to the second position, and the reset component accumulates a certain restoring force. At the same time, an external force is applied to make the rotating component 310 rotate in the opposite direction, so that the first slot 110 makes room for the first latch 340 to gradually enter. When the first slot 110 and the first latch 340 are fully engaged, no external force is applied to the rotating component 310. At this time, the reset component releases the accumulated restoring force, so that the slide rod 320 is reset from the second position to the first position, and the second slot 120 and the second latch 350 are fully engaged, thereby allowing the upper housing 100 and the lower housing 200 to re-enter the assembly state.

[0066] The housing provided by this invention is used to install a breathing circuit module. A disassembly and assembly mechanism enables the installation and disassembly of the upper housing 100 and the lower housing 200, facilitating the separation of the upper housing 100 and the lower housing 200 after each use of respiratory anesthetics for disinfection of the breathing circuit module and the housing itself. During disassembly, flipping up the rotating component 310 disengages the first latch 340 from the first slot 110, simultaneously driving the sliding rod 320 to disengage the second latch 350 from the second slot 120. Only one operation is required to completely separate the upper housing 100 and the lower housing 200, making the process simple, convenient, and quick. The reset component 330 ensures that after disassembly, the sliding rod 320 automatically returns to its first position. That is, when the upper housing 100 and the lower housing 200 are reassembled, the first latch 340 and the first slot 110, and the second latch 350 and the second slot 120, can automatically re-engage, resulting in high reuse efficiency.

[0067] Example 2

[0068] Please see Figure 1 , 3 5. In this embodiment, the slide bar 320 is provided with a plurality of second buckles 350 at intervals.

[0069] The number of second buckles 350 can be set according to actual usage needs. Any two adjacent second buckles 350 are spaced a certain distance apart. The spacing distance can be adapted according to the dimensions of the outer shell in the length direction. The spacing distances of each interval can be the same or different.

[0070] In this embodiment, two second latches 350 are spaced apart on the slide rod 320. The two second latches 350 are approximately located at both ends of the slide rod 320, with one second latch 350 located in the middle of the lower housing 200 and the other second latch 350 located near the rotating member 310. In this way, the force between the second latches 350 and the second latch groove 120 is more even and the stability is better during disassembly.

[0071] Example 3

[0072] Please see Figure 1 , 3 4 and 5, the disassembly and assembly mechanism of this embodiment also includes a fixing member 360 disposed above the slide bar 320 and fixedly connected to the lower housing 200.

[0073] Specifically, the fixing member 360 is located between the second buckle 350 and one end of the slide rod 320. When the slide rod 320 is installed between the lower housing 200 and the fixing member 360, the second buckle 350 is located on the side of the end of the fixing member 360 away from the slide rod 320, so as to offset the fixing member 360 and avoid affecting the sliding of the second buckle 350.

[0074] In this embodiment, two fixing members 360 are provided. When the slide rod 320 is installed into the lower housing 200, the two fixing members 360 are located at both ends of the slide rod 320, restricting the slide rod 320 from moving in a direction perpendicular to the length direction of the slide rod 320, so that the slide rod 320 can only slide along the length direction of the rod 320.

[0075] Example 4

[0076] Please see Figure 1 , 3 In embodiments 360, the fastener 360 has a first through hole 361 through which the second buckle 350 passes.

[0077] In this embodiment, when the slide bar 320 is installed between the lower housing 200 and the fixing member 360, the fixing member 360 has an extension portion facing the second buckle 350, and the first through hole 361 is provided on the extension portion.

[0078] In this embodiment, the second buckle 350 extends a distance in a direction that is approximately perpendicular to the length direction of the slide bar 320 and passes through the first through hole 361. The second buckle 350 can slide within the first through hole 361 to disengage the second buckle 350 from the second slot 120, and the sliding direction of the second buckle 350 can be restricted.

[0079] Example 5

[0080] Please see Figure 1 , 3 In this embodiment, the second buckle 350 is provided with a first limiting part 351 for limiting the movement of one end of the reset member 330, and the fixing member 360 is provided with a second limiting part 362 for limiting the movement of the other end of the reset member 330.

[0081] In this embodiment, one end of the reset member 330 is connected to the first limiting part 351, and the other end is connected to the second limiting part 362. It can be understood that the fixing member 360 is fixedly connected to the lower housing 200, and the slide rod 320 can drive the second buckle 350 to slide synchronously along the length direction of the lower housing 200.

[0082] Therefore, the second limiting part 362 can be regarded as a fixed fulcrum of the reset member 330. When the slide bar 320 slides from the first position to the second position, the first limiting part 351 provided on it leads one end of the reset member 330 to move synchronously and leave the initial position; the other end remains fixed, so that the reset member 330 can accumulate restoring force.

[0083] In order to make the force more balanced, the connection between the first limiting part 351 and the second limiting part 362 and the reset member 330 can be set at a position that is roughly on the same straight line.

[0084] Example 6

[0085] Please see Figure 1 , 3 In this embodiment, a slide rail is provided inside the lower housing 200. The slide rod 320 is installed on the slide rail and can slide along the slide rail. Multiple protrusions 321 are provided on the side of the slide rod 320 that contacts the fixing member 360 and the side that contacts the bottom of the slide rail.

[0086] Specifically, a stud is provided inside the slide rail, and an opening corresponding to the stud is provided on the fixing member 360. The fixing member 360 covers the slide rod 320, and the bolt passes through the opening and is connected and fixed to the stud.

[0087] In this embodiment, the front of the slide rod 320 contacts the fixing member 360, and the back of the slide rod 320 contacts the lower housing 200. When the slide rod 320 slides along the slide track, since multiple protrusions 321 are provided on both contact surfaces of the slide rod 320, the contact area between the slide rod 320 and the fixing member 360 is reduced, thereby reducing friction and avoiding problems such as jamming or inability to slide due to excessive friction.

[0088] Example 7

[0089] Please see Figure 1 , 3 In embodiments 5 and 7, the end of the slide bar 320 that abuts against the rotating member 310 is set as an arc surface.

[0090] In this embodiment, the arc surface at one end of the slide rod 320 is adapted to the rotation angle of the rotating member 310. When the rotating member 310 rotates, viewed from the side, the contact point between the rotating member 310 and the arc surface moves along the arc from the apex of the arc, thereby generating a component force along the length of the slide rod 320 to push the slide rod 320 from the first position to the second position. The smooth contact between the rotating member 310 and the arc surface of the slide rod 320 uniformly applies an external force to one end of the slide rod 320, enabling it to slide at a constant speed. Furthermore, using arc surface contact can reduce the occurrence of jamming and lower the probability of the mechanism getting stuck.

[0091] Example 8

[0092] Please see Figure 1 , 3 6 and 7, the rotating member 310 in this embodiment includes:

[0093] The rotating part 311 is provided on the lower housing 200 with a mounting groove for mounting the rotating part 311. The rotating part 311 is rotatably connected to the mounting groove. The first buckle 340 is provided on one side of the rotating part 311. The side wall of the mounting groove is provided with a second through hole for the first buckle 340 to pass through. The other side of the rotating part 311 is provided with a pull part 312 protruding from the mounting groove.

[0094] The pushing part 313 is fixed on the side of the rotating part 311 where the first buckle 340 is provided, and is located at the end of the rotating part 311 near the slide bar 320.

[0095] In this embodiment, the rotating part 311 has a main body, which is generally cylindrical. A pivot can be inserted through the cylindrical main body along its central axis. The rotating part 311 is rotatably connected to the mounting groove provided on the lower housing 200 through the pivot. The first buckle 340 and the pull part 312 can be regarded as starting from the side of the cylinder and extending in a direction generally perpendicular to the central axis of the cylinder, and the extension directions of the two are opposite to each other. A second through hole is opened on one side of the mounting groove in a direction generally perpendicular to the central axis of the cylinder, through which the first buckle 340 passes. An opening for the pull part 312 to protrude is provided on the other side. It can be understood that the directions of the second through hole and the opening are also generally opposite to each other.

[0096] When in use, an external force can be applied to the pull part 312 to drive the rotating part 311 to rotate around the axis, so that the pushing part 313 pushes the end of one end of the slide bar 320, thereby causing the slide bar 320 to slide from the first position to the second position.

[0097] Example 9

[0098] Please see Figure 1 , 3 In this embodiment, there are multiple first buckles 340, and the number of second through holes is the same as the number of first buckles 340.

[0099] The number of first buckles 340 can be set according to actual usage needs. In this embodiment, three first buckles 340 are evenly arranged at a certain distance and pass through three second through holes arranged in the same way.

[0100] Example 10

[0101] Please see Figures 1 to 3 In this embodiment, the lower housing 200 is provided with a third slot 210 at the other end opposite to the first buckle 340, and the upper housing 100 is provided with a third buckle 130 that cooperates with the third slot 210.

[0102] In this embodiment, the third slot 210 is located at the other end of the lower housing 200. That is, the first buckle 340 and the third slot 210 are respectively located at both ends of the lower housing 200 along its length. Correspondingly, the upper housing 100 has a third buckle 130 that cooperates with the third slot 210 at the end away from the rotating member 310. Through the cooperation of the third slot 210 and the third buckle 130, both ends of the housing are reinforced and fixed during assembly, preventing the lower housing 200 from accidentally separating from the upper housing 100.

[0103] Example 11

[0104] Please see Figures 1 to 7 This embodiment provides a breathing circuit module assembly, which includes a breathing circuit module and the aforementioned housing, with the breathing circuit module installed inside the housing.

[0105] In this embodiment, the breathing circuit module is used to form a circuit to deliver fresh gas and inhaled anesthetic into the patient's airway and to expel the patient's exhaled gas out of the body.

[0106] The housing provided by this invention is used to install a breathing circuit module. A disassembly and assembly mechanism enables the installation and disassembly of the upper housing 100 and the lower housing 200, facilitating the separation of the upper housing 100 and the lower housing 200 after each use of respiratory anesthetics for disinfection of the breathing circuit module and the housing itself. During disassembly, flipping up the rotating component 310 disengages the first latch 340 from the first slot 110, simultaneously driving the sliding rod 320 to disengage the second latch 350 from the second slot 120. Only one operation is required to completely separate the upper housing 100 and the lower housing 200, making the process simple, convenient, and quick. A reset component ensures that after disassembly, the sliding rod 320 automatically returns to its first position. That is, when the upper housing 100 and the lower housing 200 are reassembled, the first latch 340 and the first slot 110, and the second latch 350 and the second slot 120, can automatically re-engage, resulting in high reuse efficiency.
