Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a condensate collection device for ventilator tubing. Background Technology

[0002] When a patient is treated with a ventilator, condensation often forms in the breathing tubing of the ventilator. This condensation needs to be collected using a collection bottle. After collection, the collection bottle is removed from the ventilator and the condensation in the collection bottle is poured out.

[0003] Currently, Chinese patent CN214807673U discloses a novel condensate collection bag for ventilator tubing, comprising: a ventilator body with a receiving groove, a water collection cup placed in the receiving groove, the water collection cup storing condensate generated during humidification of the ventilator body during operation, a first connecting pipe with one end connected to the water collection cup and the other end fixedly connected to a first connector, and a drainage bag movably connected to the ventilator body with a water inlet on its outer wall, through which the condensate in the water collection cup is discharged between the water collection cup and the drainage bag via the first connecting pipe and the second connecting pipe; each of the first and second connecting pipes is provided with an adjusting device on its outer wall, and the flow rate of the condensate flowing through the first and second connecting pipes is controlled by the adjusting device; the adjusting device is a tubing clamp.

[0004] If medical staff forget to adjust the catheter clamp and fail to control the condensate flowing through the first connecting tube before separating the drainage bag from the condensate cup, the condensate will flow into the ward from the first connecting tube when the drainage bag and the condensate cup are separated, posing a significant safety hazard. Utility Model Content

[0005] To reduce safety hazards, this application provides a condensate collection device for ventilator tubing.

[0006] This application provides a condensate collection device for ventilator tubing, which adopts the following technical solution:

[0007] A ventilator tubing condensate collection device includes a connecting bottle and a collection bottle. The connecting bottle has a receiving cavity that communicates with the ventilator tubing. The collection bottle also has a collection cavity. The device further includes a sealing device comprising a sealing block, a resetting member, a connecting mechanism, and an adjusting mechanism. The connecting bottle has a communicating hole that communicates with the receiving cavity. The sealing block is rotatably mounted on the connecting bottle and can seal the communicating hole. The resetting member is mounted on the connecting bottle and connected to the sealing block. The connecting mechanism is mounted on the collection bottle and connected to the connecting bottle. When the collection bottle is connected to the connecting bottle via the connecting mechanism, the adjusting mechanism adjusts the position of the sealing block so that it no longer seals the communicating hole.

[0008] By adopting the above technical solution, the collection bottle is fully connected to the connecting bottle via a connecting mechanism. At this time, the adjusting mechanism will drive the sealing block to move, so that the sealing block no longer blocks the connecting hole. In this way, the condensate in the receiving cavity of the connecting bottle enters the collection cavity of the collection bottle through the connecting hole. When it is necessary to treat the condensate in the collection bottle, the connecting mechanism is disconnected from the connecting bottle and the collection bottle. When the collection bottle and the connecting bottle are separated, the sealing block will re-seal the connection, so that the condensate in the receiving cavity will not flow out through the connecting hole. Therefore, the sealing device can reduce safety hazards. Moreover, when treating condensate, the ventilator tubing is always connected to the connecting bottle, and the sealing block is in the state of blocking the connecting hole. This can also reduce the direct exposure of the ventilator tubing in the ward, thereby reducing cross-contamination.

[0009] Optionally, the adjustment mechanism includes a first pushing block and a second pushing block, wherein the first pushing block is disposed on the sealing block; the second pushing block is disposed on the collection bottle, and the second pushing block is capable of abutting against the first pushing block and pushing the first pushing block to move.

[0010] By adopting the above technical solution, when the collection bottle is installed on the connecting bottle, rotating the collection bottle causes the second pushing block on the collection bottle to drive the first pushing block to move. The first pushing block drives the sealing block to move, and the sealing block will no longer block the connecting hole. In this way, the condensate in the receiving cavity can enter the collection cavity through the connecting hole for collection.

[0011] Optionally, the connecting mechanism includes a first connecting block, a second connecting block, and a connecting component. The first connecting block is disposed on the connecting bottle and has an assembly cavity communicating with the communicating hole. The second connecting block is disposed on the collecting bottle, with one end of the second connecting block away from the collecting bottle positioned within the assembly cavity. The second connecting block has a collecting hole communicating with the assembly cavity and the collecting cavity. The second pushing block is disposed on the second connecting block. The connecting component is disposed on the second connecting block and connected to the first connecting block.

[0012] By adopting the above technical solution, when the second connecting block is connected to the first connecting block through the connecting assembly, the collection bottle will be fixed on the connecting bottle; the condensate in the receiving cavity of the connecting bottle will enter the collection cavity of the second connecting block through the connecting hole and the collection hole on the second connecting block for collection.

[0013] Optionally, the connecting assembly includes an external thread and an internal thread. The external thread is disposed on the outer side wall of the second connecting block, and the internal thread is disposed on the side wall of the assembly cavity, and the internal thread is threadedly connected to the external thread.

[0014] By adopting the above technical solution, when the collection bottle is rotated, the collection bottle drives the second connecting block to rotate, and the external thread on the second connecting block will be threadedly connected with the internal thread on the first connecting block, thereby fixing the second connecting block on the first connecting block, and thus fixing the collection bottle to the connecting bottle.

[0015] Optionally, the second pushing block can only abut against the first pushing block when at least two-thirds of the length of the second connecting block is connected to the first connecting block.

[0016] By adopting the above technical solution, when the second connecting block is not connected to the first connecting block for two-thirds of its length, there is a certain height difference between the second pushing block on the second connecting block and the first pushing block on the sealing block. In this way, when the collecting bottle drives the second connecting block to rotate, the second pushing block on the second connecting block will not touch the first pushing block. When the length of the second connecting block entering the assembly cavity is greater than two-thirds, the end of the second pushing block away from the second connecting block will abut against the first connecting block. In this way, when the collecting bottle rotates, the second pushing block will drive the first pushing block to rotate. Moreover, because the first pushing block has a certain thickness, when the collecting bottle rotates and causes the second pushing block to push the first pushing block to move, the second pushing block can also move relative to the first pushing block.

[0017] Optionally, a first sliding groove and a second sliding groove are provided on the side wall of the assembly cavity. The first sliding groove communicates with the second sliding groove. The connecting component includes an adjusting block, which is disposed on the outer side wall of the second connecting block. Both the first sliding groove and the second sliding groove can be slidably connected to the adjusting block.

[0018] By adopting the above technical solution, the adjusting block on the second connecting block is slid into the first sliding groove. When the adjusting block enters the second sliding groove from the first sliding groove, the second pushing block on the second connecting block and the first pushing block on the sealing block are coplanar. Then, the collection bottle is rotated so that the adjusting block moves away from the first sliding groove in the second sliding groove. In this way, the second pushing block on the second connecting block will push the first pushing block to move, so that the first pushing block drives the sealing block to move.

[0019] Optionally, the adjusting block has a limiting groove, the first connecting block has a first limiting component, the first limiting component includes a first limiting block and a first spring, the first connecting block has a first sliding hole communicating with the second sliding groove, the first limiting block is slidably disposed in the first sliding hole and engaged with the limiting groove, and the side of the first limiting block near the first sliding groove has a chamfer; one end of the first spring is connected to the first limiting block and the other end is connected to the first connecting block.

[0020] By adopting the above technical solution, when the adjusting block is located in the second slide groove, rotating the collection bottle causes the second connecting block on the collection bottle to slide the adjusting block in the second slide groove. The second pushing block then pushes the first pushing block to move, so that the sealing block no longer blocks the connecting hole. When the adjusting block moves to the vicinity of the first limiting block, the adjusting block will squeeze the chamfer on the first limiting block, and the first spring will deform. When the limiting groove on the adjusting block is aligned with the first limiting block, the force of the first spring restoring its elastic deformation drives the first limiting block to move, so that the first limiting block engages with the limiting groove. At this time, the sealing block is in a state where it does not block the connection on the connecting bottle, allowing the condensate in the receiving cavity of the connecting bottle to flow out through the connecting hole. The first limiting component can improve the stability of the adjusting block on the first connecting block, allowing the condensate in the receiving cavity to better enter the collection cavity through the connecting hole.

[0021] Optionally, the first connecting block has a groove and a second sliding hole communicating with the groove. The groove connects the first sliding groove and the second sliding groove. The first connecting block is provided with a second limiting component, which includes a second limiting block, a second spring, and a toggle block. The second limiting block is slidably disposed in the groove and can block the first sliding groove. The side of the second limiting block near the first sliding groove has a chamfer. One end of the second spring is connected to the second limiting block and the other end is connected to the first connecting block. The toggle block is slidably disposed in the second sliding hole and is connected to the second limiting block.

[0022] By adopting the above technical solution, when the adjusting block moves from the first slide groove to the second slide groove, the adjusting block will first abut against the chamfer on the second limiting block and squeeze the second limiting block into the groove, so that the adjusting block can move from the first slide groove to the second slide groove; when the adjusting block is in the second slide groove, the second limiting block blocks the first slide groove, reducing the phenomenon of the adjusting block moving from the second slide groove to the first slide groove when the collecting bottle collects condensate; the second limiting component can improve the stability when the collecting bottle and the connecting bottle are connected.

[0023] Optionally, a curing pack is provided inside the collection chamber.

[0024] By adopting the above technical solution, the curing pack can absorb the condensate in the collection chamber, reducing the spillage of collected water when medical staff transfer the collection bottle.

[0025] Optionally, the collection bottle is a rigid bottle or a plastic bag.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The sealing device reduces safety hazards. Since the ventilator tubing is always connected to the connecting bottle when dealing with condensate, the sealing block is in the state of blocking the connecting hole. This also reduces the direct exposure of the ventilator tubing in the ward, thereby reducing cross-contamination.

[0028] 2. The curing pack can absorb the condensate in the collection chamber, reducing the spillage of collected water when medical staff transfer the collection bottle. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a condensate collection device for ventilator tubing.

[0037] Example 1

[0039] refer to Figure 1 and Figure 2The connecting bottle 1 has a connecting hole 11 at the end away from the ventilator tubing 9, which communicates with the receiving cavity. The cross-section of the connecting hole 11 is fan-shaped. The sealing device 3 includes a rotating shaft 33 rotatably connected to the connecting bottle 1.

A third sliding groove 12 is provided on the connecting bottle 1. A slider 34 connected to the sealing block 31 is fixedly connected to the sealing block 31. A reset member 32 is provided in the third sliding groove 12. The reset member 32 is a third spring. One end of the third spring is connected to the slider 34 and the other end is connected to the connecting bottle 1.

[0040] refer to Figure 1 and Figure 2 A connecting mechanism 5 is provided on the connecting bottle 1. The connecting mechanism 5 includes a first connecting block 51 fixedly connected to the connecting bottle 1, and the first connecting block 51 has an assembly cavity 511 that can communicate with the communicating hole 11. A collecting bottle 2 has a collecting cavity 21, and a second connecting block 52 is fixedly connected to the collecting bottle 2. The second connecting block 52 has a collecting hole 521 that communicates with the collecting cavity 21. The end of the second connecting block 52 away from the collecting bottle 2 can be located in the assembly cavity 511 of the first connecting block 51, and the collecting hole 521 on the second connecting block 52 can communicate with the assembly cavity 511 on the first connecting block 51. Both the first connecting block 51 and the second connecting block 52 are cylindrical, and the cross-sections of the assembly cavity 511 and the collecting hole 521 are circular.

[0041] The second connecting block 52 is provided with a connecting component 53 that is connected to the first connecting block 51. The connecting component 53 includes an external thread 531 that is fixedly connected to the outer side wall of the second connecting block 52; and an internal thread 532 that is fixedly connected to the side wall of the assembly cavity 511 of the first connecting block 51. The external thread 531 on the second connecting block 52 can be threadedly connected to the internal thread 532 on the first connecting block 51.

[0042] refer to Figure 1 and Figure 2 The second connecting block 52 is provided with an adjustment mechanism 4 connected to the sealing block 31. The adjustment mechanism 4 includes a first pushing block 41 fixedly connected to the sealing block 31. The first pushing block 41 is located on the side of the sealing block 31 away from the connecting bottle 1. The second connecting block 52 is fixedly connected with an L-shaped second pushing block 42. The second pushing block 42 is located inside the collection hole 521 of the second connecting block 52 and its other end extends out of the collection hole 521 and is located outside the second connecting block 52. The second pushing block 42 can abut against the first pushing block 41 and push the first pushing block 41 to move.

[0043] A marking area is provided on the first connecting block 51. The second connecting block 52 is connected to the first connecting block 51 only when the second pushing block 42 corresponds to the marking area. Furthermore, the second pushing block 42 can only abut against the first pushing block 41 when at least two-thirds of the length of the second connecting block 52 is located within the assembly cavity 511 of the first connecting block 51.

[0044] refer to Figure 1 The collection chamber 21 of the collection bottle 2 contains a curing pack 8, which can be made of medical absorbent cotton or other medical absorbent materials.

[0045] In this embodiment, the connecting bottle 1 is a transparent rigid plastic bottle, and the collecting bottle 2 can be a transparent rigid bottle or a transparent plastic bag; the first connecting block 51, the second connecting block 52, the first pushing block 41, the second pushing block 42 and the sealing block 31 are all made of rigid materials.

[0046] The implementation principle of Embodiment 1 of this application is as follows: The second connecting block 52 is aligned with the marked area, and then the collection bottle 2 is rotated so that the external thread 531 on the second connecting block 52 is threadedly connected to the internal thread 532 on the first connecting block 51, thus connecting the second connecting block 52 to the first connecting block 51. When two-thirds of the length of the second connecting block 52 enters the assembly cavity 511 of the first connecting block 51, the second pushing block 42 on the second connecting block 52 will abut against the first pushing block 41 on the sealing block 31. Continuing to rotate the collection bottle 2, the second connecting block 52 is fully inserted into the assembly cavity 511 of the first connecting block 51. The second pushing block 42 will push the first pushing block 41 to move, and the first pushing block 41 will drive the sealing block 31 to move. The slider 34 on the sealing block 31 slides within the third groove 12 of the connecting bottle 1, and the third spring is compressed. The connecting hole 11 blocked by the sealing block 31 will then be exposed.

[0047] The condensate from the ventilator tubing 9 enters the receiving cavity of the connecting bottle 1, then through the connecting hole 11 into the collection hole 521 of the second connecting block 52, and finally into the collection cavity 21 of the collection bottle 2. The condensate entering the collection cavity 21 is absorbed by the solidification pack 8.

[0048] When the collection bottle 2 needs to be replaced periodically, rotate the collection bottle 2. When the length of the second connecting block 52, located within the assembly cavity 511 of the first connecting block 51, is less than two-thirds of its original length, the force of the third spring restoring its elastic deformation will cause the sealing block 31 to seal the connecting hole 11 on the connecting bottle 1. The condensate in the ventilator tubing 9 will then be stored in the receiving cavity of the connecting bottle 1. Continue rotating the collection bottle 2 to separate the second connecting block 52 from the first connecting block 51. Then, medical staff will discard the curing package 8 or the collection bottle 2 with the curing package 8 into the yellow waste bag, i.e., the medical waste bag. Then, medical staff will immediately install a new collection bottle 2 onto the connecting bottle 1, so that the condensate in the receiving cavity can enter the collection cavity 21 of the collection bottle 2 through the connecting hole 11 on the connecting bottle 1 and the collection hole 521 on the collection bottle 2.

[0049] Example 2

[0050] refer to Figure 3 and Figure 4 The difference from Embodiment 1 is that the connecting component 53 includes an adjusting block. The first connecting block 51 has a first sliding groove 512 and a second sliding groove 513 that communicate with the assembly cavity 511. The first sliding groove 512 is also connected to the second sliding groove 513. The axis of the first sliding groove 512 is parallel to the axis of the first connecting block 51, and both the first sliding groove 512 and the second sliding groove 513 can be slidably connected to the adjusting block.

[0051] refer to Figure 4 and Figure 5 The first connecting block 51 has a groove, and the first sliding groove 512 and the second sliding groove 513 can communicate with the groove; the first connecting block 51 has a second sliding hole 514 communicating with the groove, and the second sliding hole 514 is connected to the groove on the side of the groove away from the second sliding groove 513 and also on the side of the first connecting block 51 away from the assembly cavity 511.

[0052] A second limiting component 7 is provided on the first connecting block 51. The second limiting component 7 includes a second limiting block 71 slidably connected in the groove. The second limiting block 71 can block the first sliding groove 512. The side of the second limiting block 71 near the first sliding groove 512 has a chamfer. A second spring 72 is provided in the groove. One end of the second spring 72 is connected to the second limiting block 71 and the other end is connected to the first connecting block 51. A toggle block 73 is integrally provided on the second limiting block 71 located in the groove. The end of the toggle block 73 away from the second limiting block 71 passes through the second sliding hole 514 and is located outside the first connecting block 51. The toggle block 73 can be slidably disposed in the second sliding hole 514.

[0053] refer to Figure 5The adjusting block has a limiting groove, and the first connecting block 51 has a first sliding hole communicating with the second sliding groove 513. The first connecting block 51 is provided with a first limiting component 6, which includes a first limiting block 61 slidably connected in the first sliding hole. One end of the first limiting block 61 is located in the second sliding groove 513 and the other end is located outside the first connecting block 51. The first limiting block 61 located in the second sliding groove 513 has a chamfer on the side facing the first sliding groove 512, and the chamfered first limiting block 61 can engage with the limiting groove on the adjusting block. A fixing block 63 is fixedly connected to the end of the first limiting block 61 away from the second sliding groove 513. A first spring 62 is sleeved on the first limiting block 61 between the fixing block 63 and the first connecting block 51. One end of the first spring 62 is connected to the first limiting block 61 and the other end is connected to the first connecting block 51.

[0054] The implementation principle of Embodiment 2 of this application is as follows: Medical personnel first align the adjusting block with the first groove 512 on the first connecting block 51, and then move the collection bottle 2 towards the connecting bottle 1. The adjusting block on the second connecting block 52 will then slide into the first groove 512 on the first connecting block 51. When the adjusting block moves from the first groove 512 to the second groove 513, the adjusting block will first abut against the chamfer on the second limiting block 71, pressing the second limiting block 71 into the groove of the first connecting block 51, so that the adjusting block can move from the first groove 512 to the second groove 513. When the adjusting block is located in the second slide groove 513, the second pushing block 42 on the second connecting block 52 is coplanar with the first pushing block 41 on the sealing block 31. When the collecting bottle 2 is rotated, the second connecting block 52 on the collecting bottle 2 drives the adjusting block to slide in the second slide groove 513, and the second pushing block 42 will push the first pushing block 41 to move, so that the sealing block 31 no longer blocks the connecting hole 11. When the adjusting block moves to the vicinity of the first limiting block 61, the adjusting block will squeeze the chamfer on the first limiting block 61, and the first spring 62 will be stretched. When the limiting groove on the adjusting block is aligned with the first limiting block 61, the force of the first spring 62 restoring its elastic deformation drives the first limiting block 61 to move, so that the first limiting block 61 is engaged with the limiting groove on the adjusting block. At this time, the sealing block 31 is in a state where it does not block the connection on the connecting bottle 1, and the third spring is in a compressed state. That is, the condensate in the receiving cavity of the connecting bottle 1 can flow out through the connecting hole 11.

[0055] When it is necessary to replace collection bottle 2, medical staff first pull the fixing block 63, which drives the first limiting block 61 to move, so that the first limiting block 61 separates from the limiting groove on the adjusting block; then the medical staff rotates collection bottle 2, and the second connecting block 52 on collection bottle 2 drives the adjusting block to move. When it moves to the vicinity of the second limiting block 71, the medical staff first adjusts the toggle block 73, which drives the second limiting block 71 to move, so that the limiting block no longer blocks the first sliding groove 512. Then the medical staff adjusts collection bottle 2, so that the adjusting block enters from the second sliding groove 513 into the first sliding groove 512 and finally slides out from the first sliding groove 512, thus separating collection bottle 2 from connecting bottle 1.

[0056] When medical staff do not rotate the collection bottle 2 or when the rotation force is small, the second spring 72 remains in a normal state, that is, the adjusting block cannot drive the second limiting block 71 to move.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
