Description

Technical Field

[0001] This invention belongs to the field of medical drainage bag collection and treatment technology, specifically referring to a device for collecting waste fluid from peritoneal dialysis for kidney disease. Background Technology

[0002] Peritoneal dialysis produces a large amount of fluid containing metabolic waste, which is usually collected through a drainage tube and collection bag worn by the patient and changed regularly. The replaced collection bag needs to be placed in a special container for collection because the fluid inside may contain viruses or other infectious pathogens.

[0003] However, since the collection bags are not completely sealed, if the collection bags are thrown directly into the bucket, a small amount of leaked liquid will contaminate the outer surface of the collection bags, posing a safety hazard to the subsequent sorting process during centralized processing. In order to centrally destroy the collected liquid in the collection bags, the liquid inside needs to be separated from the liquid and stored separately. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, this solution proposes a device that can collect liquid in the drainage bag in a centralized manner; in order to avoid leakage during the liquid discharge process, this invention proposes a bottle mouth clamping component and a rubber valve, which deforms the bottle mouth by clamping it, thereby changing the rubber valve from a closed state to an open state, thereby avoiding the problem of internal liquid leakage when the bottle mouth is naturally facing down. To simplify the structure and operation, the present invention also proposes a squeezing assembly and a sliding guide assembly. By driving the drive shaft, the two rubber wheels can be brought close together and clamped to form a collection bag. Then, while the collection bag is clamped, it is pushed upward to squeeze the liquid in the collection bag through the bottle mouth.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a waste fluid collection device for peritoneal dialysis in kidney disease, including a squeezing assembly, a sliding guide assembly, a bottle mouth clamping assembly, a driving assembly, a collection bag, and a box assembly. The squeezing assembly is disposed on the sliding guide assembly, the sliding guide assembly is disposed in the box assembly, the bottle mouth clamping assembly is disposed on the sliding guide assembly, the driving assembly is rotatably disposed in the box assembly, and the collection bag is located between two sets of squeezing assemblies.

[0006] Furthermore, the extrusion assembly includes an extrusion shaft, a rubber wheel, a transverse gear, and a transverse rack. The extrusion shaft is rotatably disposed in the sliding guide assembly, the rubber wheel and the transverse gear are fixedly connected to the outside of the extrusion shaft, and the transverse rack is fixedly connected to the sliding guide assembly.

[0007] By designing the length of the transverse rack, the transverse movement and rotation of the extrusion shaft can be sequentially controlled, thereby achieving the technical effect of first approaching and then extruding.

[0008] Furthermore, the sliding guide assembly includes a sliding bracket, a slider, and a return spring. The sliding bracket is fixedly connected to the housing assembly, the slider is engaged and slidably disposed in the sliding bracket, and the return spring is disposed between the sliding bracket and the slider.

[0009] By rotating the drive assembly, the two rubber wheels are first brought close together and clamped to the collection bag. Then, the rotation of the rubber wheels gradually squeezes the collection bag from the end near the drainage tube, allowing the liquid in the collection bag to be discharged.

[0010] Preferably, the extrusion shaft is rotatably disposed in the slider, the transverse rack is fixedly connected to the top wall of the sliding bracket, and the transverse gear and the transverse rack mesh and transmit power.

[0011] Furthermore, the bottle neck clamping assembly includes a longitudinal support, a longitudinal slide bar, an arc-shaped crimp connector, and a liquid collection tube. The longitudinal support is fixed to the slider, the longitudinal slide bar is engaged and slidably mounted on the longitudinal support, the arc-shaped crimp connector is fixed to the bottom of the longitudinal slide bar, and the liquid collection tube is fixed to the lower part of one of the arc-shaped crimp connectors.

[0012] The arc-shaped crimp connector is not a standard semicircle. When the two arc-shaped crimp connectors are closed, they can not only clamp and fix the bottle mouth, but also change the rubber valve from a closed state to an open state by squeezing and deforming.

[0013] Furthermore, the bottom of the collection bag is provided with a bottle mouth, and a rubber valve is provided in the bottle mouth. When the two arc-shaped pressure joints are attached and squeezed together, the rubber valve can be changed from a closed state to an open state.

[0014] Furthermore, the drive assembly includes a drive shaft, a drive gear, and a telescopic universal joint. The drive shaft is rotatably mounted on the side wall of the housing assembly. The drive gear is fixed to the drive shaft, and the two drive gears mesh and transmit power. The two ends of the telescopic universal joint are respectively connected to the drive shaft and the extrusion shaft. Both ends of the telescopic universal joint are universal joint structures.

[0015] Preferably, the top of the collection bag is also provided with a drainage tube.

[0016] The telescopic universal joint can maintain the power transmission between the extrusion shaft and the drive shaft during the lateral sliding of the extrusion shaft. The two ends of the telescopic universal joint can be cross universal joints or ball cage universal joints, or other forms that meet the working conditions.

[0017] Furthermore, the housing assembly includes a barrel and a partition, the sliding bracket is fixedly connected to the inside of the barrel, the bottom of the barrel is provided with casters, the side of the barrel is provided with a handle, the partition is fixedly connected to the barrel, and the partition is provided with a flip-up baffle.

[0018] Preferably, the box assembly further includes a liquid collection box and a packaging collection box, wherein the liquid collection box is detachably disposed in the barrel, the end of the liquid collection pipe is connected to the liquid collection box, and the packaging collection box is detachably disposed in the barrel.

[0019] Both the collection box and the packaging collection box are designed to be pulled out, allowing for easy cleaning of the medical waste inside a specific area.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows: (1) By designing the length of the transverse rack, the transverse movement and rotation of the extrusion shaft can be controlled sequentially, thereby achieving the technical effect of first approaching and then extruding.

[0021] (2) By rotating the drive assembly, the two rubber wheels can first be brought close together and clamped to the collection bag. Then, by rotating the rubber wheels, the collection bag is gradually squeezed from the end near the drainage tube, so that the liquid in the collection bag can be discharged.

[0022] (3) The arc-shaped crimping joint is not a standard semicircle. When the two arc-shaped crimping joints are closed, they can not only clamp and fix the bottle mouth, but also change the rubber valve from the closed state to the open state by squeezing and deforming.

[0023] (4) The telescopic universal joint can maintain the power transmission between the extrusion shaft and the drive shaft during the lateral sliding of the extrusion shaft. The two ends of the telescopic universal joint can be cross universal joints or ball cage universal joints, or other forms that meet the working conditions.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] like Figures 1-11 As shown, the present invention proposes a waste fluid collection device for peritoneal dialysis in kidney disease, including a squeezing assembly 1, a sliding guide assembly 2, a bottle mouth clamping assembly 3, a driving assembly 4, a collection bag 5, and a box assembly 6. The squeezing assembly 1 is disposed on the sliding guide assembly 2, the sliding guide assembly 2 is disposed in the box assembly 6, the bottle mouth clamping assembly 3 is disposed on the sliding guide assembly 2, the driving assembly 4 is rotatably disposed in the box assembly 6, and the collection bag 5 is located between the two sets of squeezing assemblies 1.

[0031] The extrusion assembly 1 includes an extrusion shaft 11, a rubber wheel 12, a transverse gear 13, and a transverse rack 14. The extrusion shaft 11 is rotatably disposed in the sliding guide assembly 2. The rubber wheel 12 and the transverse gear 13 are fixedly connected to the outside of the extrusion shaft 11, and the transverse rack 14 is fixedly connected to the sliding guide assembly 2.

[0032] By designing the length of the transverse rack 14, the transverse movement and rotation of the extrusion shaft 11 can be controlled sequentially, thereby achieving the technical effect of first approaching and then extruding.

[0033] The sliding guide assembly 2 includes a sliding bracket 21, a slider 22 and a return spring 23. The sliding bracket 21 is fixed in the housing assembly 6, the slider 22 is engaged and slidably disposed in the sliding bracket 21, and the return spring 23 is disposed between the sliding bracket 21 and the slider 22.

[0034] By rotating the drive assembly 4, the two rubber wheels 12 can first be brought close together and clamped to the collection bag 5. Then, by rotating the rubber wheels 12, the collection bag 5 is gradually squeezed from the end near the drainage tube 51, so that the liquid in the collection bag 5 can be discharged.

[0035] The extrusion shaft 11 is rotatably mounted in the slider 22, and the transverse rack 14 is fixed to the top wall of the sliding bracket 21. The transverse gear 13 and the transverse rack 14 mesh and transmit power.

[0036] The bottle mouth clamping assembly 3 includes a longitudinal support 31, a longitudinal slide bar 32, an arc-shaped crimp connector 33, and a liquid collection tube 34. The longitudinal support 31 is fixed to the slider 22, the longitudinal slide bar 32 is engaged and slidably disposed on the longitudinal support 31, the arc-shaped crimp connector 33 is fixed to the bottom of the longitudinal slide bar 32, and the liquid collection tube 34 is fixed to the lower part of one of the arc-shaped crimp connectors 33.

[0037] The arc-shaped crimp connector 33 is not a standard semicircle. When the two arc-shaped crimp connectors 33 are closed, they can not only clamp and fix the bottle mouth 52, but also change the rubber valve 53 from the closed state to the open state by squeezing and deforming.

[0038] The bottom of the collection bag 5 is provided with a bottle mouth 52, and a rubber valve 53 is provided in the bottle mouth 52. When the two arc-shaped pressure joints 33 are attached and squeezed, the rubber valve 53 can be changed from a closed state to an open state.

[0039] The drive assembly 4 includes a drive shaft 41, a drive gear 42, and a telescopic universal joint 43. The drive shaft 41 is rotatably mounted on the side wall of the housing assembly 6. The drive gear 42 is fixedly connected to the drive shaft 41, and the two drive gears 42 mesh and transmit power. The two ends of the telescopic universal joint 43 are respectively connected to the drive shaft 41 and the extrusion shaft 11. Both ends of the telescopic universal joint 43 are universal joint structures.

[0040] The top of the collection bag 5 is also provided with a drainage tube 51.

[0041] The telescopic universal joint 43 can maintain the power transmission between the extrusion shaft 11 and the drive shaft 41 during the lateral sliding of the extrusion shaft 11. The two ends of the telescopic universal joint 43 can be cross universal joints or ball cage universal joints, or other forms that meet the working conditions.

[0042] The housing assembly 6 includes a barrel 61 and a partition 62. A sliding bracket 21 is fixed inside the barrel 61. The bottom of the barrel 61 is provided with casters 611. A handle is provided on the side of the barrel 61. The partition 62 is fixed inside the barrel 61. A baffle 621 that can be flipped is provided on the partition 62.

[0043] The housing assembly 6 also includes a liquid collection box 63 and a packaging collection box 64. The liquid collection box 63 is detachably installed in the barrel 61, and the end of the liquid collection pipe 34 is connected to the liquid collection box 63. The packaging collection box 64 is detachably installed in the barrel 61.

[0044] Both the collection box 63 and the packaging collection box 64 are designed to be removable, allowing for the cleaning of medical waste in specific areas.

[0045] In actual use, the waste fluid on the patient enters the collection bag 5 through the drainage tube 51. There is no gas in the collection bag 5, and the liquid that enters can expand the collection bag 5. After use, the collection bag 5 needs to be collected and cleaned. Medical staff hold the drainage tube 51 and suspend the collection bag 5 in the correct position. Because the liquid in the collection bag 5 is less than its maximum volume, when the collection bag 5 is hoisted, the liquid is located in the lower half of the collection bag 5, and the upper half of the collection bag 5 is in a flat state with the two sides touching. When suspended, the height of the rubber wheel 12 should be the same as the height of the upper flat part of the collection bag 5, the bottle mouth 52 and the arc-shaped crimp joint 33.

[0046] Then turn on the power, and the motor drives one of the drive shafts 41 to rotate. Since the two drive gears 42 mesh with each other, the two drive shafts 41 drive the two extrusion shafts 11 to rotate at the same speed and in opposite directions.

[0047] Since the transverse gear 13 and the transverse rack 14 are meshed, when the transverse gear 13 rotates, it will first drive the slider 22 to slide towards the middle position until the transverse gear 13 and the transverse rack 14 are separated. At this time, even if the squeezing shaft 11 continues to rotate, the slider 22 will remain stationary (or slide back and forth within a very small range). Since the rubber wheel 12 has the ability to deform, the rubber wheel 12 can always resist and squeeze the collection bag 5.

[0048] As the slider 22 slides along with the sliding bracket 21, the two arc-shaped pressure joints 33 gradually approach each other and complete the compression and fixation of the bottle mouth 52. At this time, on the one hand, the arc-shaped pressure joints 33 can form a sealed connection with the bottle mouth 52, and on the other hand, due to the deformation of the rubber valve 53 by compression, the rubber valve 53 will also change from a closed state to an open state. After the slider 22 stops, the rubber wheel 12 has also completed the contact and compression of the collection bag 5.

[0049] Then, the rotating shaft 11 continues to rotate with the rubber wheel 12. The collection bag 5 gradually rises under the pressure and push of the rubber wheel 12, thereby squeezing out the liquid in the collection bag 5 in a manner similar to squeezing toothpaste. The liquid discharged from the collection bag 5 enters the collection box 63 after passing through the one-way valve of the collection pipe 34.

[0050] As the collection bag 5 rises, the arc-shaped pressure joint 33 and the longitudinal slide bar 32 also rise synchronously. After the liquid is discharged, the control drive shaft 41 is reversed, which immediately separates and resets the two rubber wheels 12. After the two arc-shaped pressure joints 33 are separated, they will also slowly reset under their own weight.

[0051] Then, the medical staff will twist the drainage tube 51 into a ball and release it together with the collection bag 5. The collection bag 5 will then push open the baffle 621 and enter the packaging collection box 64, completing the separation of the liquid and the packaging.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
