Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a bladder irrigation device. Background Technology

[0002] Bladder irrigation is a method that uses a catheter to infuse irrigation fluid into the bladder, and then uses the siphon principle to drain the infused fluid out, in order to achieve medical purposes such as maintaining unobstructed urine flow and removing foreign objects from the bladder.

[0003] Existing irrigation systems are generally used in conjunction with matching catheters or urine bags. These catheters or urine bags share common characteristics: each end has a separate connection point that connects to the irrigation system, allowing irrigation fluid to enter the bladder through the catheter for irrigation. However, the connection point is inseparable from the catheter or urine bag assembly, and the catheter or urine bag assembly must be compatible with the irrigation system for it to function. When a standard catheter or urine bag assembly is used for drainage, it cannot be connected to the irrigation system. To perform irrigation properly, one method is to replace the standard catheter or urine bag assembly with one compatible with the irrigation system, but this can cause patient discomfort. Another method is to use a syringe to inject irrigation fluid into the catheter, but this carries a high risk of infection and compromises the integrity of the catheter, posing a risk of leakage. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a bladder irrigation device that optimizes the connection between existing irrigation structures and catheters, improves the compatibility between ordinary catheters or urine bag assemblies and the irrigation structure, and protects the overall integrity of the catheter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bladder irrigation device, comprising:

[0007] A urinary catheter is used to drain urine.

[0008] Urine bag assembly for receiving urine and flushing fluid;

[0009] A flushing structure for storing and transporting flushing fluid to the catheter; and,

[0010] The three-way connection structure includes a connection body, three connection ends, and a regulating valve. The three connection ends are disposed on the periphery of the connection body and are respectively connected to the urinary catheter, the urine bag assembly, and the flushing structure via hoses. The regulating valve is disposed on the connection body and is used to control the opening and closing of the pipeline between the urinary catheter and the urine bag assembly and between the urinary catheter and the flushing structure.

[0011] The connecting end has multiple connectors of different diameters integrally formed inside. The connectors are arranged coaxially along the end of the connecting end toward the connecting body in a decreasing diameter pattern, and form a first channel that connects the inside of the connecting body.

[0012] Preferably, the end of the connecting end away from the connecting body has a mounting groove on its surface facing the central axis, and the mounting groove is provided with an elastic clamping member.

[0013] Preferably, the connecting end further includes a positioning sleeve, which is clamped to the connecting end by the elastic clamping member, for guiding the pipe to be inserted into the connecting end.

[0014] Preferably, the inner diameter of the positioning sleeve is larger than the diameter of the connector near the end of the connecting end.

[0015] Preferably, the elastic clamping member includes a spring and an arc-shaped plate. One end of the spring is connected to the groove wall of the mounting groove, and the other end is connected to the arc-shaped plate. The surface of the arc-shaped plate facing away from the spring is in close contact with the pipe.

[0016] Preferably, the regulating valve includes a valve body and a handle. The valve body has a second channel inside. The second channel forms a first flow path with the urinary catheter, the urine bag assembly and the corresponding connecting end. The second channel forms a second flow path with the urinary catheter, the flushing structure and the corresponding connecting end. One end of the handle is connected to the center of the valve body, and the other end protrudes from the connecting body for rotating to switch between the first flow path and the second flow path.

[0017] Preferably, the valve body has a limiting protrusion on the surface opposite to the handle, and the connecting body has a corresponding arc-shaped groove. The limiting protrusion moves within the range of the arc-shaped groove to determine the rotation position of the regulating valve.

[0018] Preferably, an air balloon is provided at the end of the catheter away from the three-way connection structure.

[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0020] The three-way connector has three connection ends, which connect to the urinary catheter, urine bag assembly, and flushing structure respectively via flexible tubing, enabling detachable connections. It is suitable for urinary catheters and urine bag assemblies without built-in flushing tubing. The connection ends have multiple connectors of different sizes to accommodate tubing of different diameters, ensuring good versatility. It is also equipped with positioning sleeves and elastic clamps to allow for quick and stable installation and connection of the tubing to the connection ends.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] To resolve the above issues, please refer to [link / reference]. Figures 1 to 6 This utility model provides a bladder irrigation device, including a urinary catheter 1, a urine bag assembly 2, an irrigation structure 3, and a three-way connection structure 4. The urinary catheter 1 is used to drain urine; the urine bag assembly 2 is used to receive urine and irrigation fluid; the irrigation structure 3 is used to store irrigation fluid and transport irrigation fluid to the urinary catheter 1; the three-way connection structure 4 includes a connecting body 41, three connecting ends 42, and a regulating valve 43. The three connecting ends 42 are disposed on the periphery of the connecting body 41 and are respectively connected to the urinary catheter 1, the urine bag assembly 2, and the irrigation structure 3 via flexible tubes. The regulating valve 43 is disposed on the connecting body 41 and is used to control the opening and closing of the pipeline between the urinary catheter 1 and the urine bag assembly 2 and between the urinary catheter 1 and the irrigation structure 3; wherein, multiple connectors 421 of different diameters are integrally formed inside the connecting ends 42. The connectors 421 are arranged coaxially along the direction from the end of the connecting end 42 toward the connecting body 41 in a decreasing diameter pattern, and form a first channel 422 communicating with the inside of the connecting body 41.

[0033] The three-way connection structure 4 is made of polyethylene through injection molding, which has high hardness and high permeability, effectively preventing cracking. At the same time, the internal regulating valve 43 can be directly observed through the three-way connection structure 4 to determine the direction of the regulating valve 43's torsion, allowing medical staff to quickly turn the regulating valve 43 to the required position. The urine bag assembly 2 consists of a tubing and a collection bag body. One end of the tubing is detachably connected to the collection bag body, and the other end is inserted into the corresponding connection end 42. The flushing structure 3 includes a tubing and a reservoir bag containing flushing fluid. The reservoir bag is detachably connected to one end of the tubing and connected to the corresponding connection end 42 through the other end of the tubing.

[0034] In optional embodiments, such as Figure 4 As shown, the end of the connecting end 42 away from the connecting body 41 has a mounting groove 423 on its surface facing the central axis. The mounting groove 423 is provided with an elastic clamping member 5. The elastic clamping member 5 can be a combination of a spring and a clamping plate, etc. By setting the elastic clamping member 5, the end of the hose connected to the tee connection structure 4 is clamped. The elastic clamping member 5 can automatically adjust the clamping range according to the size of the hose to improve the connection strength and stability between the hose and the tee connection structure 4. Furthermore, this clamping method will not affect the medical staff's ability to assemble and disassemble the hose.

[0035] In optional embodiments, such as Figure 1 and Figure 3 As shown, the connecting end 42 also includes a positioning sleeve 424, which is clamped to the connecting end 42 by the elastic clamping member 5, and is used to guide the tube to be inserted into the connecting end 42. The positioning sleeve 424 has a T-shaped structure, with the smaller diameter end inserted into the connecting end 42 and its periphery limited by the elastic clamping member 5. At this time, the elastic clamping member 5 is in a compressed state, and the larger diameter end protrudes from the connecting end 42 with a certain gap. Furthermore, when the elastic clamping member 5 is restricted to a compressed state by the positioning sleeve 424, the tubing can be quickly inserted into the connecting end 42 to connect to the corresponding size connector 421. After the tubing and connector 421 are connected by an interference fit, medical personnel can remove the positioning sleeve 424 from the connecting end 42 through the gap, so that the clamping member 5 is clamped. The holding function changes from the periphery of the positioning sleeve 424 to the periphery of the hose, effectively avoiding the influence of the elastic clamp 5 during hose installation and improving the smoothness of hose connection. At this time, the positioning sleeve 424 can move arbitrarily along the length of the hose. The positioning sleeve 424 is lightweight and will not pull on the naturally hanging hose. Furthermore, in order to facilitate the installation of the positioning sleeve 424 on the connecting end 42, the end of the positioning sleeve 424 installed on the connecting end 42 is a hollow frustum structure. The diameter of the hollow frustum structure gradually decreases along the central axis of the positioning sleeve 424 toward the connecting body 41.

[0036] In optional embodiments, such as Figure 3As shown, the inner diameter of the positioning sleeve 424 is larger than the diameter of the connector 421 near the end of the connecting end 42. Specifically, the inner diameter of the positioning sleeve 424 is larger than the maximum outer diameter of the pipe that the connecting end 42 can connect to, so that hoses of different standard sizes can pass through the positioning sleeve 424 and be connected to the corresponding connector 421; furthermore, the end of each connector 421 also has a partially tapered appearance to facilitate the connection of the hose to the connector 421.

[0037] In optional embodiments, such as Figure 4 As shown, the elastic clamping member 5 includes a spring 51 and an arc-shaped plate 52. One end of the spring 51 is connected to the groove wall of the mounting groove 423, and the other end is connected to the arc-shaped plate 52. The surface of the arc-shaped plate 52 facing away from the spring 51 is in close contact with the pipe. In this embodiment, three elastic clamping members 5 are provided, but in actual applications, the number can be designed according to requirements and arranged in a circumferential array on the corresponding surface of the connecting end 42 to clamp the hose rear positioning sleeve 424 from three directions, so as to facilitate the stable installation of the hose and the positioning sleeve 424. At the same time, the curvature of the arc-shaped plate 52 is consistent with that of the hose and the positioning sleeve 424. When the elastic clamping member 5 clamps the hose and the positioning sleeve 424, the contact surface of the arc-shaped plate 52 is in close contact with both, improving the clamping stability.

[0038] In optional embodiments, such as Figure 6As shown, the regulating valve 43 includes a valve body 431 and a handle 432. The valve body 431 has a second channel 433 inside. The second channel 433 forms a first flow path 6 with the urinary catheter 1, the urine bag assembly 2 and the corresponding connecting end 42. The second channel 433 forms a second flow path 7 with the urinary catheter 1, the flushing structure 3 and the corresponding connecting end 42. One end of the handle 432 is connected to the center of the valve body 431, and the other end protrudes from the connecting body 41 for rotating to switch between the first flow path 6 and the second flow path 7. Specifically, a limiting post 434 is provided on the surface of the valve body 431 opposite to the handle 432, and a limiting groove 411 is provided on the connecting body 41. The valve body 431 is stably installed on the connecting body 41 by inserting the limiting post 434 into the limiting groove 411. A clearance hole is opened on the side of the connecting body 41 corresponding to the handle 432. The handle 432 passes through the clearance hole into the connecting body 41 and connects with the surface of the valve body 431 opposite to the limiting post 434. In this embodiment, three channels are provided inside the connecting body 41, distributed around the periphery of the valve body 431, and respectively correspond to the catheter 1, the urine bag assembly 2, and the flushing structure 3. When the above three are connected to the corresponding connecting body through a hose, After the connector 42, its corresponding first channel 422 corresponds one-to-one with the three channels of the connecting body 41. The end of the channel connecting the urinary catheter 1 and the valve body 431 is divided into a first branch 412 and a second branch 413. The urinary catheter 1 and the urine bag assembly 2 are connected to the first branch 412 through the second channel 433 to form a passage, thus forming a first flow path 6. The urinary catheter 1 and the flushing structure 3 are connected to the second branch 413 through the second channel 433 to form a passage, thus forming a second flow path 7. Medical staff can control the opening and closing of the first flow path 6 and the second flow path 7 by rotating the valve body 431 through the handle 432 to perform different operations, such as flushing and drainage.

[0039] In optional embodiments, such as Figure 6 As shown, the valve body 431 has a limiting protrusion 435 on its surface opposite to the handle 432, and the connecting body 41 has a corresponding arc-shaped groove 414. The limiting protrusion 435 moves within the arc-shaped groove 414 to determine the rotation position of the regulating valve 43. When the first flow path 6 is open, the limiting protrusion 435 is located at one edge of the arc-shaped groove 414; when the second flow path 7 is open, the limiting protrusion 435 is located at the other edge of the arc-shaped groove 414, thus determining whether the valve body 431 has rotated to the correct position to align with the channel of the connecting body 41.

[0040] In optional embodiments, such as Figure 1As shown, an air balloon 11 is provided at the end of the urinary catheter 1 away from the three-way connection structure 4. The urinary catheter 1 is an air balloon catheter 1. After the end of the urinary catheter 1 with the air balloon 11 is inserted into the bladder, the air balloon 11 is inflated through the air inflator channel of the urinary catheter 1, which fixes one end of the urinary catheter 1 in the bladder, making it difficult for one end of the urinary catheter 1 to fall out of the bladder.

[0041] In use, the catheter 1, urine bag assembly 2, and flushing structure 3 are inserted through the positioning sleeve 424 into the connector 421 at the corresponding connecting end 42 of the three-way connection structure 4. In this embodiment, the catheter 1 and urine bag assembly 2 are connected to the two opposite connecting ends 42 of the three-way connection structure 4, and the flushing structure 3 is connected to the middle connecting end 42, facilitating the collection of urine or flushing fluid and flushing into the bladder. After the tubing is connected to the connector 421, the positioning sleeve 424 is removed from the connecting end 42, and the elastic clamp 5... The clamping object changes from the positioning sleeve 424 to a flexible tube. After all the flexible tubes are installed, medical staff can rotate the valve body 431 through the handle 432, so that the second channel 433 in the valve body 431 connects with a different channel in the connecting body 41 to realize the passage of the first flow path 6 or the second flow path 7. When the first flow path 6 is opened, the urine or flushing fluid in the bladder can flow to the urinary pad assembly through the first flow path 6. When the second flow path 7 is opened, the flushing fluid in the flushing structure 3 enters the catheter 1 through the second flow path 7 and is introduced into the bladder.

[0042] In summary, the three-way connection structure 4 has three connection ends 42, which are respectively connected to the urinary catheter 1, the urine bag assembly 2, and the flushing structure 3 via flexible tubes, achieving detachable connection. It is suitable for urinary catheters 1 and urine bag assemblies 2 without their own flushing tubes. The connection ends 42 are equipped with multiple connectors 421 of different sizes to accommodate flexible tubes of different diameters, providing good versatility. They are also equipped with positioning sleeves 424 and elastic clamps 5 to allow for quick installation and stable connection of the flexible tubes to the connection ends 42. The three-way connection structure 4 is equipped with a regulating valve 43. When medical staff rotate the regulating valve 43, the urinary catheter 1 and the urine bag assembly 2, and the urinary catheter 1 and the flushing structure 3 are connected through the second pipe of the regulating valve 43 to accommodate different nursing operations such as flushing or drainage.
