Description

Technical Field

[0001] This utility model relates to the field of urinary catheterization kit technology, specifically a urinary catheterization kit with a drainage structure. Background Technology

[0002] A urinary catheterization kit with drainage structure is a medical device used for urinary catheter drainage. It is mainly used to collect and guide urine to help patients excrete urine after certain medical treatments or surgeries.

[0003] For example, a urinary catheter with a drainage structure, disclosed in CN219110353U, includes a urinary catheter consisting of a first shell, a second shell, and a base plate. A urinary catheter is fixedly installed at the middle of the upper end of the first shell. A threaded insertion hole is opened on one side of the first shell of the urinary catheter. The lower end of the first shell is welded to the second shell. Guide grooves are symmetrically opened on both sides of the interior of the second shell, and the lower end of the second shell is welded to the base plate. A drainage tube is fixedly installed at the lower end of the base plate. When there is excessive urine at night, the urine will push the sealing support plate downward under the action of its own gravity, thereby making the rubber sealing ring no longer in contact with the bottom surface of the first shell. In this way, the urine can flow down from the gap between the sealing support plate and the second shell into the second shell, and then be discharged through the drainage tube, realizing the automatic discharge of urine and avoiding the phenomenon of urine backflow.

[0004] The aforementioned patent proposes that urine can flow down from the gap between the sealing support plate and the second shell into the second shell, and then be discharged through the drainage tube. However, during the use of the urinary catheter, when the patient's posture changes, the drainage tube is easily compressed, causing the drainage tube to become blocked, resulting in poor urine drainage and affecting normal urine discharge.

[0005] Therefore, we propose a catheterization kit with a drainage structure to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a urinary catheter with a drainage structure to solve the problem mentioned in the background art, where changes in the patient's posture can easily compress the drainage tube, causing it to become blocked and resulting in poor urine drainage, thus affecting normal urine output.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a urinary catheterization kit with a drainage structure, comprising a urinary catheterization kit structure and a drainage tube connected to the urinary catheterization kit structure. The drainage tube is used to drain urine. An anti-pressure structure is provided on the outside of the drainage tube, and a connecting structure is provided on the outer wall of the anti-pressure structure. The drainage tube can be wrapped by the cooperation of the anti-pressure structure and the connecting structure.

[0008] The pressure-resistant structure includes a pressure-resistant ring fitted on the outside of the drainage tube and an inner cavity formed inside the pressure-resistant ring. A connecting block is provided in the inner cavity, and a support ring is provided on the side of the connecting block near the drainage tube. A rubber pad is provided on the inner wall of the support ring. Multiple sets of connecting blocks and support rings are provided and evenly distributed in the inner cavity. By fitting the pressure-resistant ring on the outside of the drainage tube, the drainage tube can be protected against pressure. Furthermore, the connecting block and support ring can effectively ensure the straightness of the drainage tube within the pressure-resistant ring and reduce the resistance to liquid flow.

[0009] Preferably, the anti-pressure structure further includes moisture-absorbing cotton disposed in the inner cavity. Two sets of moisture-absorbing cotton are disposed, and the two sets of moisture-absorbing cotton are symmetrically distributed about the center line of the anti-pressure ring, so as to absorb moisture.

[0010] Preferably, the urinary catheterization kit structure has connectors at both the top and bottom ends. One set of connectors is equipped with a urinary catheter, and the other set of connectors is connected to a drainage tube. The inner wall of the urinary catheterization kit structure is also provided with an inner bag layer, which can increase the overall thickness of the urinary catheterization kit structure.

[0011] Preferably, the lower end of the connector is provided with a connecting ring, and a mounting groove is formed on the surface of the connecting ring for use with the connecting structure.

[0012] Preferably, the connection structure includes a hinge seat disposed on the outside of the anti-pressure ring and a limiting block disposed on the inside of the hinge seat. A connecting shaft is also inserted through the surface of the hinge seat and the limiting block. A nut is threaded on one end of the connecting shaft. By flipping the limiting block, one end of the limiting block can be inserted into the mounting groove, and then fixed by the cooperation of the connecting shaft and the nut.

[0013] Preferably, the connection structure is provided in two sets, and the two sets of connection structures are symmetrically distributed about the center line of the anti-pressure ring. The cross-section of the limiting block is inverted L shape, and one end of the limiting block is adapted to the mounting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Through the design of the urinary catheterization kit, drainage tube, connecting structure, and anti-pressure structure, the anti-pressure structure is placed outside the drainage tube using the connecting structure. When the drainage tube is in use, it can effectively avoid being compressed, allowing the urine in the drainage tube to drain smoothly. At the same time, the drainage tube can remain straight within the anti-pressure ring, avoiding bending, reducing resistance to fluid flow, and preventing blockage.

[0016] 2. The absorbent cotton inside can absorb moisture, effectively keep the area dry, and prevent the growth of bacteria. Attached Figure Description

A rubber pad 35 is provided on the inner wall of the support ring 34. Multiple sets of connecting blocks 33 and support rings 34 are provided and evenly distributed in the inner cavity 32. Sleeving the anti-pressure ring 31 on the outside of the drainage tube 2 can protect the drainage tube 2 from pressure. Furthermore, the connecting blocks 33 and support rings 34 can effectively ensure the straightness of the drainage tube 2 within the anti-pressure ring 31, reduce the resistance to liquid flow, and avoid blockage.

[0025] The urinary catheterization pack structure 1 has connectors 11 at both the top and bottom. One set of connectors 11 is equipped with a urinary catheter 12, and the other set of connectors 11 is connected to a drainage tube 2. The inner wall of the urinary catheterization pack structure 1 is also equipped with an inner bag layer 13, which can increase the overall thickness of the urinary catheterization pack structure 1 and has good tensile strength.

[0026] The lower end of the connector 11 is provided with a connecting ring 14. The connecting ring 14 is located on the side of the catheterization bag structure 1 near the drainage tube 2. A placement groove 15 is provided on the surface of the connecting ring 14. The placement groove 15 is used to cooperate with the connecting structure 4, so that the anti-pressure structure 3 can be placed on the outside of the drainage tube 2.

[0027] The connecting structure 4 includes a hinge seat 41 located on the outside of the anti-pressure ring 31 and a limiting block 43 located on the inside of the hinge seat 41. A connecting shaft 42 is also inserted through the surface of the hinge seat 41 and the limiting block 43. A nut 44 is threaded onto one end of the connecting shaft 42. By flipping the limiting block 43, one end of the limiting block 43 can be inserted into the mounting groove 15. Then, the connecting shaft 42 and the nut 44 are used to fix the limiting block 43.

[0028] The connection structure 4 is provided in two sets, and the two sets of connection structures 4 are symmetrically distributed about the center line of the anti-pressure ring 31. The cross-section of the limiting block 43 is inverted L shape, and one end of the limiting block 43 is adapted to the mounting groove 15.

[0029] In this embodiment: the anti-pressure ring 31 is placed on the outside of the drainage tube 2 and close to the connecting ring 14. Then, the limiting block 43 is flipped so that one end of the limiting block 43 can be inserted into the placement groove 15. Then, the limiting block 43 is fixed by the cooperation of the connecting shaft 42 and the nut 44, so that the anti-pressure ring 31 can be fixed on the outside of the drainage tube 2. The anti-pressure ring 31 can effectively prevent the drainage tube 2 from being pressed, so that the drainage tube 2 flows smoothly. The connecting block 33 and the support ring 34, which are evenly distributed in the inner cavity 32, can effectively support the drainage tube 2, which can ensure the straightness of the drainage tube 2 in the anti-pressure ring 31, reduce the resistance of liquid flow, avoid blockage, and facilitate the discharge of urine in the drainage tube 2.

[0030] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The anti-pressure structure 3 also includes moisture-absorbing cotton 36 disposed in the inner cavity 32. There are two sets of moisture-absorbing cotton 36, and the two sets of moisture-absorbing cotton 36 are symmetrically distributed about the center line of the anti-pressure ring 31, which can absorb moisture.

[0031] In this embodiment, two sets of absorbent cotton 36 are installed on the top and bottom walls of the inner cavity 32 respectively, and can absorb moisture at the upper and lower openings of the anti-pressure ring 31, thereby effectively preventing the growth of bacteria.

[0032] Working principle: The anti-pressure ring 31 is placed on the outside of the drainage tube 2 and close to the connecting ring 14. Then, the limiting block 43 is flipped so that one end of the limiting block 43 can be inserted into the placement groove 15. Then, the connecting shaft 42 and the nut 44 are used to fix it, thereby fixing the limiting block 43. This allows the anti-pressure ring 31 to be fixed on the outside of the drainage tube 2. The anti-pressure ring 31 can effectively prevent the drainage tube 2 from being pressed down, so that the drainage tube 2 flows smoothly. The connecting block 33 and the support ring 34, which are evenly distributed in the inner cavity 32, can effectively support the drainage tube 2, ensuring the straightness of the drainage tube 2 in the anti-pressure ring 31 and reducing the resistance to liquid flow. Two sets of moisture-absorbing cotton 36 are installed on the top and bottom walls of the inner cavity 32, respectively, and can absorb moisture at the upper and lower openings of the anti-pressure ring 31.
