Description

Technical Field

[0001] The present application relates to the technical field of waste liquid collection bags, and in particular to a waste liquid collection bag with an exhaust valve. Background Art

[0002] Waste liquid collection bags are used to collect waste liquid generated during the patient's dialysis process to ensure environmental hygiene, safety and sanitation. They play an important role in medical care and help reduce cross-infection and the spread of infectious diseases.

[0003] After being used multiple times, a large amount of air will enter the traditional waste liquid collection bag. Due to the lack of exhaust structure, when the traditional waste liquid collection bag is used again, liquid and air will exist inside the waste liquid collection bag at the same time, causing bulging inside the waste liquid collection bag. During the operation by medical staff, the waste liquid collection bag is very likely to rupture, causing waste liquid to leak, which is not conducive to practical application and operation.

[0004] Therefore, those skilled in the art provide a waste liquid collection bag with an exhaust valve to solve the problems raised in the above background technology. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a waste liquid collection bag with an exhaust valve, which solves the problem mentioned in the above background technology that a large amount of air will enter the inside of the traditional waste liquid collection bag after multiple uses.

During the operation by medical staff, the waste liquid collection bag is very likely to rupture, causing waste liquid to leak, which is not conducive to practical application and operation.

[0006] To achieve the above objectives, the present application is implemented through the following technical solutions: a waste liquid collection bag with an exhaust valve, comprising a waste liquid bag, an exhaust pipe is installed on the top of the waste liquid bag, an exhaust hole is opened on the top of the exhaust pipe, an exhaust assembly is arranged on the outside of the exhaust pipe, and a sealing assembly is arranged inside the exhaust pipe;

[0007] The exhaust assembly is used to cooperate with the exhaust pipe to realize the communication between the waste liquid bag and the outside air.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below through drawings and examples.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4, an embodiment of the present application provides a waste liquid collection bag with an exhaust valve, including a waste liquid bag 1. The waste liquid bag 1 is made of polyethylene or polypropylene, and the waste liquid bag 1 is transparent, which is convenient for observing the liquid inside. An exhaust pipe 2 is installed on the top of the waste liquid bag 1, and the exhaust pipe 2 is connected to the inside of the waste liquid bag 1. An exhaust hole 3 is opened on the top of the exhaust pipe 2, and the exhaust hole 3 is used to cooperate with the exhaust pipe 2 to achieve exhaust. An exhaust assembly is arranged on the outside of the exhaust pipe 2, and a sealing assembly is arranged inside the exhaust pipe 2.

[0031] By providing an exhaust component in conjunction with a sealing component, the air inside the waste liquid bag 1 can be discharged when collecting waste liquid, thereby avoiding bulging inside the waste liquid bag 1 after multiple uses, allowing medical staff to better discharge the waste liquid, and at the same time avoiding the waste liquid bag 1 from being easily damaged due to bulging, which is beneficial to practical application and operation.

[0032] A liquid inlet pipe 11 is installed at the top of the waste liquid bag 1, a liquid discharge pipe 12 is installed at the bottom of the waste liquid bag 1, and a valve 13 is installed on the outside of the liquid discharge pipe 12. The liquid inlet pipe 11 is used to facilitate the liquid inlet into the waste liquid bag 1. The liquid discharge pipe 12 is used to facilitate the liquid discharge from the waste liquid bag 1, and the valve 13 can be used to close the liquid discharge pipe 12.

[0033] A hanging belt 14 is installed on the top of the waste liquid bag 1. The hanging belt 14 can be used to conveniently hang the waste liquid bag 1.

[0034] The waste liquid bag 1 is provided with a scale mark 15 on the outside, and a label placement bag 16 is installed on the outside of the waste liquid bag 1 and on one side of the scale mark 15. The scale mark 15 is used to facilitate reading the volume of the liquid inside the waste liquid bag 1. The label placement bag 16 is used to facilitate placing an indicator label.

[0035] Reference Figure 4 In one aspect of this embodiment, the exhaust assembly is used to cooperate with the exhaust pipe 2 to connect the waste liquid bag 1 with the outside air. The sealing assembly is used to seal the exhaust hole 3.

[0036] The exhaust assembly includes an exhaust cover 4, a fixing ring 5, a spring 6 and four exhaust grooves 7. The exhaust cover 4 is threadedly connected to the outside of the exhaust pipe 2. The fixing ring 5 is rotatably connected to the bottom of the exhaust cover 4. The inner diameter of the fixing ring 5 is larger than the outer diameter of the exhaust pipe 2. The spring 6 is fixedly connected between the bottom of the fixing ring 5 and the top of the waste liquid bag 1. The spring 6 is located on the outside of the exhaust pipe 2. The exhaust cover 4 can be prevented from rotating easily due to the shaking of the waste liquid bag 1 by using the spring 6. Four exhaust grooves 7 are equidistantly arranged on the top of the exhaust cover 4.

[0037] When exhaust operation is required, the exhaust cover 4 can be turned to drive the fixing ring 5 to move downward, squeeze the spring 6 at the same time, and drive the sealing assembly to move downward. When the sealing assembly no longer seals the exhaust hole 3, the air inside the waste liquid bag 1 will be connected to the outside world. When liquid continues to enter the waste liquid bag 1, the air inside the waste liquid bag 1 is discharged from the exhaust hole 3 to the inside of the exhaust cover 4, and finally the exhaust operation is realized through the exhaust groove 7.

[0038] A filter screen 17 is installed inside the exhaust groove 7. The filter screen 17 can be used to block impurities and prevent external impurities from entering the interior of the device through the exhaust groove 7.

[0039] Reference Figure 4 In one aspect of the present embodiment, the sealing assembly includes a fixing rod 8, a sealing plug 9 and a sealing ring 10. The fixing rod 8 is fixed to the bottom of the inner wall of the exhaust cover 4. The bottom of the fixing rod 8 passes through the exhaust hole 3 and extends to the inside of the exhaust pipe 2. The sealing plug 9 rotates at the bottom of the fixing rod 8. The sealing ring 10 is fixed to the top of the sealing plug 9 and is located on the outside of the fixing rod 8.

[0040] When the exhaust cover 4 is turned to drive the fixing ring 5 to move downward, the fixing rod 8 and the sealing plug 9 can be driven to move downward. At this time, the sealing plug 9 and the sealing ring 10 will no longer seal the exhaust hole 3. When sealing is required, the exhaust cover 4 can be turned in the opposite direction to drive the fixing ring 5 to move upward. At the same time, the fixing rod 8 and the sealing plug 9 can be driven to move upward, so that the sealing plug 9 squeezes the sealing ring 10 and contacts the top of the inner wall of the exhaust pipe 2, thereby realizing the sealing operation of the exhaust hole 3.

[0041] Reference Figure 4 In one aspect of this embodiment, the inner diameter of the sealing ring 10 is smaller than the diameter of the exhaust hole 3, and the outer diameter of the sealing ring 10 is larger than the diameter of the exhaust hole 3. By using the sealing plug 9, the sealing ring 10 can be pressed against the outer side of the exhaust hole 3, thereby completing the sealing operation of the exhaust hole 3.

[0042] Working principle:

[0043] When in use, the waste liquid bag 1 is first hung by the hanging belt 14, and then liquid can be added into the waste liquid bag 1 through the liquid inlet pipe 11;

[0044] When exhaust operation is needed, the exhaust cover 4 can be screwed to drive the fixing ring 5 to move downward, and at the same time, the spring 6 can be squeezed to drive the fixing rod 8 and the sealing plug 9 to move downward. At this time, the sealing plug 9 and the sealing ring 10 will no longer seal the exhaust hole 3. At this time, the air inside the waste liquid bag 1 will be connected to the outside world. When liquid continues to enter the waste liquid bag 1, the air inside the waste liquid bag 1 is discharged from the exhaust hole 3 to the inside of the exhaust cover 4, and finally the exhaust operation is realized through the exhaust groove 7;

[0045] When sealing is required, the exhaust cover 4 can be screwed in the opposite direction to drive the fixing ring 5 to move upward, and at the same time, the fixing rod 8 and the sealing plug 9 can be driven to move upward, so that the sealing plug 9 squeezes the sealing ring 10 and contacts the top of the inner wall of the exhaust pipe 2, thereby achieving the sealing operation of the exhaust hole 3;

[0046] By providing an exhaust component in conjunction with a sealing component, the air inside the waste liquid bag 1 can be discharged when collecting waste liquid, thereby avoiding bulging inside the waste liquid bag 1 after multiple uses, allowing medical staff to better discharge the waste liquid, and at the same time avoiding the waste liquid bag 1 from being easily damaged due to bulging, which is beneficial to practical application and operation.

[0047] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
