[0039] Due to the condition of some patients, bladder irrigation and urine collection are performed regularly according to the doctor's instructions. Bladder irrigation is to use a catheter to inject a solution into the bladder, and then use the siphon principle to drain the injected liquid into the urine bag. Urine collection is to take out the urine in the urine bag for testing.

[0040] Currently, the sampling device on the urine bag is often used for bladder washing and urine collection for testing. Repeated punctures may lead to the risk of catheter leakage and urinary tract infection.

[0041] To this end, the utility model designs a catheterization bladder flushing test diversion device, which uses the entire device as a conversion connector, and uses a positioning component to position the entire device on the sampling device of the urine bag, and is connected to the bladder flushing device or syringe through a positive pressure connector. Therefore, when performing bladder flushing and urine extraction, there is no need to pierce the sampling device, but it can be directly connected to the liquid inlet position of the device, thereby reducing the risk of repeated punctures and the risk of urinary tract infection.

[0042] The specific embodiments of the present invention are described in detail below in conjunction with the urinary catheterization bladder flushing laboratory diversion device of the present invention.

[0043] like Figures 1 to 5 As shown, this embodiment discloses a catheterization bladder flushing test diversion device, including a housing 1, a positioning assembly 3 and a positive pressure connector 2.

[0044] The interior of the shell 1 is configured as an infusion cavity. A liquid inlet 11 is provided at one end of the shell 1, and a puncture needle 4 suitable for connecting to a sampling device on a urine bag is provided at the other end of the shell 1. The liquid inlet 11 and the puncture needle 4 are respectively connected to the infusion cavity.

[0045] The positioning assembly 3 is arranged on the housing 1 and is suitable for being detachably connected to the sampling device on the urine bag.

[0046] The positive pressure connector 2 is arranged inside the infusion cavity, and the positive pressure connector 2 is suitable for opening the liquid inlet 11 when subjected to external force and blocking the liquid inlet 11 when not subjected to external force.

[0047] The above-mentioned catheterization bladder flushing test diversion device has a positioning component 3 that is detachably arranged on the sampling device on the urine bag and is provided with a positive pressure connector 2. Therefore, when bladder flushing and urine extraction are not performed, the positive pressure connector 2 blocks the liquid inlet 11; when bladder flushing is performed, the bladder flushing device is connected to the positive pressure connector 2 and generates an extrusion pressure on the positive pressure connector 2, and then the positive pressure connector 2 is turned on, and the urine after flushing the bladder will pass through the infusion cavity of the device and the puncture needle 4 into the urine bag; when urine extraction is performed, the syringe can be inserted into the positive pressure connector 2 to generate an extrusion pressure on the positive pressure connector 2, and then the positive pressure connector 2 is turned on, and the syringe extracts the urine in the urine bag. In this embodiment, the positioning component 3 is used to detachably position the entire device on the sampling device on the urine bag. It can be connected to both the bladder flushing device and the syringe. At the same time, the liquid inlet 11 can be blocked when there is no external force. Therefore, there is no need to repeatedly puncture the sampling device on the urine bag during bladder flushing and urine extraction. The device can be used as a conversion device for urine collection and extraction, reducing the risk of repeated punctures and the risk of urinary tract infection.

[0048] At present, when urine is collected for testing, sometimes the syringe and the urine bag do not match, resulting in the syringe being unable to collect urine. Therefore, a catheterization bladder flushing test diversion device designed in this embodiment provides a fixed position liquid inlet 11 for the connection of the syringe, and the set liquid inlet 11 matches the syringe model, thereby avoiding the problem that the syringe and the urine bag do not match and cannot collect urine.

[0049] In some embodiments, the positive pressure connector 2 includes a blocking plate 22, a fixed bracket 25 and a spring 23. The fixed bracket 25 is fixedly arranged on the inner wall of the infusion cavity, and at least one liquid through hole 252 is provided on the fixed bracket 25. One end of the spring 23 is connected to the blocking plate 22, and the other end of the spring 23 is connected to the fixed bracket 25. In this embodiment, the blocking plate 22 can automatically block the liquid inlet 11 under the action of the spring 23. When the device is connected to the bladder flushing device, the infusion cylinder on the bladder flushing device will be inserted into the liquid inlet 11 and push the blocking plate 22, thereby connecting the liquid inlet 11 with the infusion cavity. When the device is connected to the syringe, the cylindrical head on the syringe will be inserted into the liquid inlet 11 and push the blocking plate 22, thereby connecting the liquid inlet 11 with the infusion cavity.

[0050] In some embodiments, the fixed bracket 25 is further provided with a sliding hole 251; the blocking plate 22 is connected with a sliding shaft 24 that can slide through the sliding hole 251, and the sliding shaft 24 and the liquid inlet 11 are respectively located on both sides of the blocking plate 22. In this embodiment, the sliding shaft 24 can prevent the blocking plate 22 from being easily offset when approaching or moving away from the liquid inlet 11.

[0051] In some embodiments, an annular convex plate 21 is provided at the liquid inlet 11 of the shell, and the annular convex plate 21 points to the infusion cavity inside the shell. The sealing plate 22 is provided below the infusion cavity. The annular convex plate 21 provides an installation position for the bladder flushing device and the syringe.

[0052] In some embodiments, the positioning component 3 is a snap-on positioning component, which is used to detachably position the device on the sampling device of the urine bag, making disassembly and installation very convenient.

[0053] More specifically, the snap-fit ​​positioning assembly includes a first snap ring 31 and a second snap ring 32. The first snap ring 31 is connected to the outer wall of the housing 1. One end of the second snap ring 32 is hinged to the first snap ring 31 through a hinge 33, and the other end of the second snap ring 32 is a movable end snap-fitted to the first snap ring 31. When the second snap ring 32 rotates, it can form an annular snap-fitting cavity with the first snap ring 31 suitable for snapping the sampling device on the urine bag.

[0054] A first clamping plate 36 is extended outward from one end of the first clamping ring 31 that is not hinged to the second clamping ring 32, and a second clamping plate 37 is extended outward from one end of the second clamping ring 32 that is not hinged to the first clamping ring 31. The first clamping plate 36 is provided with a plurality of clamping protrusions 34, and the second clamping ring 32 is provided with a plurality of clamping grooves 35. The clamping protrusions 34 can be clamped into the clamping grooves 35.

[0055] In this embodiment, after the puncture needle 4 is inserted into the sampling device of the urine bag, the second clamp ring 32 is rotated, and the housing is clamped onto the sampling device through the first clamp ring 31 and the second clamp ring 32, and then the clamping protrusion 34 is pressed into the clamping groove 35, thereby achieving the fixation of the first clamp ring 31 and the second clamp ring 32; when the housing needs to be removed from the sampling device, it can be achieved by pulling the second clamp ring 32. In this embodiment, the housing is conveniently positioned on the sampling device by clamping the clamping protrusion 34 into the clamping groove 35, so that the puncture needle 4 does not need to repeatedly puncture the sampling device when performing bladder flushing and urine extraction.

[0056] In some embodiments, an outer wall of the housing 1 is provided with an external thread 6 suitable for connecting with a bladder irrigation device. In this embodiment, the external thread 6 provided on the side wall of the housing 1 is used to achieve effective connection with the bladder irrigation device.

[0057] In some embodiments, a plurality of strip-shaped protrusions 5 arranged at intervals are provided on the outer side wall of the housing 1, which can increase the friction with the human hand and facilitate the human hand to hold and rotate the housing.

[0058] In some embodiments, the shell 1 is configured to be in a conical cylindrical shape, and may also be configured to be in other shapes, and its specific shape is not limited here.

[0059] The specific use process of the utility model is:

[0060] Insert the puncture needle 4 into the sampling device of the urine bag, and use the buckle positioning assembly to position the housing on the sampling device of the urine bag to achieve the overall positioning of the utility model;

[0061] When bladder irrigation is performed, the bladder irrigation device is threadedly positioned on the housing and inserted into the liquid inlet 11, the blocking plate 22 is squeezed, and the liquid inlet 11 is opened. The flushing speed of the bladder irrigation device is adjusted according to demand. The liquid in the bladder enters the urine bag through the infusion cavity and the puncture needle 4. After the bladder irrigation is completed, the bladder irrigation device is removed, and the blocking plate 22 re-blocks the liquid inlet 11 under the action of the spring 23.

[0062] When collecting urine, the syringe is inserted into the liquid inlet 11, the sealing plate 22 is squeezed, and the liquid inlet 11 is opened. The liquid in the urine bag is extracted by the suction effect of the syringe. After the urine is collected, the liquid collector is removed, and the sealing plate 22 re-seals the liquid inlet 11 under the action of the spring 23.

[0063] The advantages of the utility model are: on the one hand, bladder flushing at different speeds can be performed according to needs, and on the other hand, urine sample volume can be taken, thereby maximizing the convenience of operation for nursing staff and improving work efficiency.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
