Description

Technical Field

[0001] This application relates to the field of catheter valve technology, and in particular to a convenient catheter valve. Background Technology

[0002] A catheter valve is a small device, usually installed at the tip of the catheter, used to control the flow of urine. It ensures that only the necessary amount of urine is expelled from the catheter during urination, preventing excessive leakage. When removing urine, the valve allows the urine to flow out slowly, giving doctors or nurses sufficient time to observe and ensure a adequate urine sample is collected.

[0003] Chinese patent CN201701640U discloses a urinary catheter valve, which includes a valve body with a left valve core and a right valve core at both ends. Both valve cores have radial through holes. A left inlet tube and a right inlet tube are located on one radial side of the valve body, and a left outlet tube and a right outlet tube are located opposite each other on the other radial side of the valve body. The opening and closing of the left and right inlet tubes, and the opening and closing of the right inlet and right outlet tubes, are controlled by rotating the left and right valve cores. This invention has a simple structure, conveniently controls urine output or the duration of drug action in the bladder, and can be tightly connected to drainage bags, syringes, irrigation tubes, etc., greatly reducing drug waste.

[0004] Regarding the aforementioned technologies, in the prior art, the urination operation is completed by rotating the left valve core to connect the hole inside the left valve core with the valve body. However, in order to ensure the sealing between the valve core and the valve body, there is a certain degree of tightness between the valve core and the valve body. Thus, during operation, one hand needs to hold the valve body and the other hand needs to rotate the valve core, requiring both hands to complete the operation. This increases the number of operation steps for the urinary catheter valve and increases the complexity of the operation of the urinary catheter valve. Utility Model Content

[0005] To improve the ease of operation of catheter valves, this application provides an easy-to-operate catheter valve.

[0006] The urinary catheter valve provided in this application adopts the following technical solution:

[0007] A convenient-to-operate urinary catheter valve includes a valve body, a valve core, and a valve cover. The valve body is provided with an installation groove, an inlet tube, and an outlet tube, which are connected. The valve core is slidably fitted in the installation groove. The valve core has inlet notches corresponding to the positions of the inlet and outlet tubes, and a drain notch is provided between the two inlet notches. An ejector is provided in the installation groove for ejecting the valve core. The valve cover is detachably connected to the opening of the installation groove. A pressure block is slidably fitted on the valve cover, and the pressure block abuts against the valve core. The valve cover is provided with a reset element to return the pressure block to its initial position, and a limiting element to restrict the movement of the pressure block is provided on the pressure block.

[0008] By adopting the above technical solution, during urination, pressure is applied to the pressure block, causing it to move and driving the valve core to move until the inlet connects the inlet and outlet urinary tubes. Then, a limiting component restricts the movement of the pressure block, achieving the effect of opening the urinary catheter valve. When closing, the limiting component is released, and the ejector component moves the valve core, causing the inner wall of the valve core to seal the inlet and outlet urinary tubes, achieving the effect of closing the urinary catheter valve. By pressing the pressure block with one hand to open the urinary catheter valve and then operating the limiting component to restrict the movement of the pressure block, the entire opening and closing of the urinary catheter valve can be completed with one hand. Compared with existing technologies, this reduces the number of operating steps for the urinary catheter valve and improves its ease of operation.

[0009] Optionally, the reset element is a reset spring, the valve cover is provided with a pressure groove, the pressure block is slidably fitted in the pressure groove, a receiving ring groove is provided between the pressure groove and the pressure block, the reset element is sleeved in the receiving ring groove and is located between the valve cover and the pressure block.

[0010] By adopting the above technical solution, when resetting the pressure block, the limiting part is released, and the elastic force of the reset spring is used to push the pressure block to move in the opposite direction until the pressure block can no longer move, thus achieving the effect of resetting the pressure block.

[0011] Optionally, the limiting member is a limiting pin, which is L-shaped and slides horizontally within the pressure block. A positioning ring groove is provided on the inner ring wall of the receiving ring groove. When urine is being passed through, the end of the limiting member is located within the positioning ring groove.

[0012] By adopting the above technical solution, when the water inlet connects the urine inlet tube and the urine outlet tube, the limiting member is pushed, the limiting member moves, and its end enters the positioning ring groove. Under the action of the resetting member, the limiting member abuts against the side wall of the positioning ring groove to limit the degree of freedom of the pressing block, thereby achieving the effect of limiting the pressing block.

[0013] Optionally, the valve body is provided with a connecting ring groove at the opening of the mounting groove, the valve cover is provided with a mounting ring groove, and a limiting ring is connected to the ring wall of the mounting ring groove. During installation, the valve cover is fitted onto the opening of the mounting groove through the mounting ring groove, and the limiting ring is embedded in the connecting ring groove.

[0014] By adopting the above technical solution, when installing the valve cover, the valve cover is placed on the groove of the mounting groove, and pressure is applied to the valve cover to make the limiting ring embedded in the connecting ring groove, thereby restricting the degree of freedom of the valve cover and realizing the installation of the valve cover; when disassembling, the valve cover is pulled by force to make the limiting ring disengage from the mounting ring groove.

[0015] Optionally, a limiting block is connected to the valve core, and a limiting groove is opened at the position of the mounting groove corresponding to the limiting block, and the limiting block is slidably fitted in the limiting groove.

[0016] By adopting the above technical solution, the valve core can be moved in its original state within the installation groove through the cooperation of the limiting block and the limiting groove, ensuring that the water inlet notch is aligned with the urine inlet or outlet pipe.

[0017] Optionally, a sealing ring is provided on the valve cover, and the sealing ring is located between the valve cover and the valve body.

[0018] By adopting the above technical solution, the sealing ring is used to improve the sealing between the valve cover and the valve body, further reducing the possibility of urine leakage from the valve cover.

[0019] Optionally, the inlet catheter is provided with a limiting component for restricting the catheter.

[0020] By adopting the above technical solution, a detachable connection between the urinary catheter and the inlet catheter is achieved through the limiting component.

[0021] Optionally, the limiting component includes a retaining ring and a blocking ring. Several retaining rings are connected to the inlet tube. The cross-section of the retaining ring is triangular. The thickness of the retaining ring gradually increases from the inlet tube to the valve core. The blocking ring is connected to the inlet tube and is located between the retaining ring and the valve core.

[0022] By adopting the above technical solution, when installing the urinary catheter, one end of the urinary catheter is fitted onto the retaining ring, and the urinary catheter is moved until one end of the urinary catheter touches the retaining ring. At this time, one end of the urinary catheter is deformed due to the gradually increasing diameter of the retaining ring. Through the stress of the internal material of the urinary catheter, the friction between the urinary catheter and the inlet tube is increased, thereby restricting the movement of the urinary catheter and realizing the installation of the urinary catheter.

[0023] Optionally, the limiting component includes a fixing ring and a rotating cylinder. The fixing ring is connected to the inlet tube, and the inlet tube is provided with a threaded section. The rotating cylinder is threaded onto the threaded section, and a plurality of abutting flanges are connected to the inner ring wall of the rotating cylinder. When the urinary catheter is installed, the end of the urinary catheter is sleeved on the inlet tube and located inside the rotating cylinder, and the abutting flanges abut against the urinary catheter.

[0024] By adopting the above technical solution, when installing the urinary catheter, one end of the urinary catheter is fitted onto the inlet tube, and then the rotating cylinder is moved and rotated. As the rotating cylinder moves, it gradually covers one end of the urinary catheter, pressing the flange against the urinary catheter, causing the urinary catheter to deform. This increases the friction between the urinary catheter and the inlet tube, thereby restricting the degree of freedom of one end of the urinary catheter and realizing the installation of the urinary catheter.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. During urination, pressure is applied to the pressure block, causing it to move and thus the valve core to move until the inlet connects the inlet and outlet urinary tubes. Then, the limiting element restricts the movement of the pressure block, achieving the effect of opening the urinary catheter valve. To close, the limiting element is released, and the ejector element moves the valve core, causing the inner wall of the valve core to block the inlet and outlet urinary tubes, achieving the effect of closing the urinary catheter valve. By pressing the pressure block with one hand to open the urinary catheter valve and then operating the limiting element to restrict the movement of the pressure block, the entire opening and closing of the urinary catheter valve can be completed with one hand. Compared to existing technologies, this reduces the number of operating steps for the urinary catheter valve and improves its ease of operation.

[0027] 2. When the inlet gap connects the inlet and outlet urine tubes, the limiting component is pushed, and the limiting component moves and its end enters the positioning ring groove. Under the action of the resetting component, the limiting component presses against the side wall of the positioning ring groove to limit the degree of freedom of the pressure block, thus achieving the effect of limiting the pressure block.

[0028] 3. When installing the urinary catheter, place one end of the urinary catheter onto the inlet tube, then move and rotate the rotating cylinder. As the rotating cylinder moves, it gradually covers one end of the urinary catheter, pressing against the flange to tighten the urinary catheter, causing the urinary catheter to deform. This increases the friction between the urinary catheter and the inlet tube, thereby restricting the freedom of one end of the urinary catheter and realizing the installation of the urinary catheter.

[0035] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0036] Embodiment 1 of this application discloses a convenient-to-operate catheter valve. (Refer to...) Figure 1 and Figure 2 The easy-to-operate urinary catheter valve includes a valve body 1, a valve core 2, and a valve cover 3. The valve body 1 has an integrally formed inlet tube 11 and an outlet tube 12. The valve body 1 is provided with an installation groove 13, and both the inlet tube 11 and the outlet tube 12 are connected to the installation groove 13.

[0037] Reference Figure 2 and Figure 3 The valve core 2 is a cylinder, and several limiting blocks 21 are fixedly connected to it. In this embodiment, two blocks are used as an example. A limiting groove is opened in the mounting groove 13 at the position corresponding to the limiting block 21. The valve core 2 slides in and out of the limiting groove through the limiting block 21. A water inlet notch 22 is opened on the valve core 2 at the position corresponding to the inlet tube 11 and the outlet tube 12. A drain notch 23 is provided between the two water inlet notches 22. An ejector 131 is provided in the mounting groove 13. The ejector 131 is an ejection spring and is located between the valve core 2 and the bottom wall of the mounting groove 13.

[0038] Reference Figure 3 A connecting ring groove is provided on the valve body 1 at the position corresponding to the opening of the mounting groove 13. A mounting ring groove is provided on the valve cover 3, and a limiting ring 31 is fixedly connected to the ring wall of the mounting ring groove. The valve cover 3 is fitted onto the opening of the mounting groove 13 through the mounting ring groove, and the limiting ring 31 is embedded in the connecting ring groove.

[0039] Reference Figure 2 and Figure 3The valve cover 3 has a pressure groove, and a pressure block 4 is installed in the pressure groove. The pressure block 4 abuts against the end of the valve core 2, and a receiving annular groove 5 is formed between the inner wall of the pressure groove and the pressure block 4. The valve cover 3 is provided with a reset element 51, which is a reset spring. The reset element 51 is installed in the receiving annular groove 5 and is located between the valve cover 3 and the pressure block 4.

[0040] Reference Figure 2 and Figure 3 The pressure block 4 is provided with a limiting element 41, which is a limiting pin and is L-shaped. The pressure block 4 has a sliding groove, and the limiting element 41 slides within the sliding groove. The inner wall of the receiving ring groove 5 has a positioning ring groove 52.

[0041] When urinating, press the pressure block 4 to compress the reset member 51, causing the valve core 2 to move and the ejector member 131 to be compressed until the water inlet 22 connects to the urine inlet tube 11. Push the restrictor member 41 so that the end of the restrictor member 41 enters the positioning ring groove 52. The restrictor member 41 presses against the inner wall of the positioning ring groove 52 by the force of the reset member 51, thereby restricting the degree of freedom of the pressure block 4 and achieving the effect of urinating. When closing, release the restrictor member 41. The pressure block 4 moves in the opposite direction by the force of the reset member 51, and the valve core 2 moves in the opposite direction by the force of the ejector member 131 until the inner wall of the valve core 2 blocks the urine inlet tube 11, thereby closing the valve body 1.

[0042] Reference Figure 3 To improve the sealing between the valve cover 3 and the valve body 1, a sealing groove is provided on the valve cover 3, and a sealing ring 6, which is a rubber ring, is fitted inside the sealing groove. The sealing ring 6 is used to reduce the possibility of urine leakage at the valve cover 3.

[0043] Reference Figure 1 and Figure 3 A limiting component 7 is provided on the inlet catheter 11. The limiting component 7 includes a clamping ring 71 and a retaining ring 72. Several clamping rings 71 are fixedly connected to the inlet catheter 11. The cross-section of the clamping ring 71 is triangular. Taking the end of the inlet catheter 11 to the valve core 2 as the reference direction, the thickness of the clamping ring 71 gradually increases. The retaining ring 72 is fixedly connected to the inlet catheter 11 and is located between the clamping rings 71 and the valve core 2.

[0044] When installing the urinary catheter, one end of the catheter is fitted onto the inlet tube 11 until it touches the retaining ring 72. At this time, one end of the catheter is deformed by the retaining ring 71, thereby increasing the friction between the catheter and the inlet tube 11, thus restricting the movement of the catheter and realizing the installation of the urinary catheter.

[0045] The implementation principle of a convenient urinary catheter valve in Embodiment 1 of this application is as follows: When the valve body 1 is opened, the pressure block 4 is pressed, causing the pressure block 4 to move. The reset member 51 is compressed, the valve core 2 moves, and the ejector member 131 is compressed until the inlet gap 22 connects to the urinary inlet tube 11. The limiting member 41 is pushed, causing the end of the limiting member 41 to enter the positioning ring groove 52, thereby limiting the movement of the pressure block 4. When the valve body 1 is closed, the limiting member 41 is released, and the pressure block 4 moves in the opposite direction under the force of the reset member 51. The valve core 2 moves in the opposite direction under the force of the ejector member 131, and the side wall of the valve core 2 closes the urinary inlet tube 11, thereby achieving the effect of closing the valve body 1.

[0046] The catheter valve can be opened by pressing the pressure block 4 with one hand, and then the limiting member 41 can be operated to restrict the movement of the pressure block 4. In this way, the opening and closing of the entire catheter valve can be completed by one hand. Compared with the existing technology, the operation steps of the catheter valve are reduced and the operation convenience of the catheter valve is improved.

[0047] Example 2: The difference between this example and Example 1 is that the structure of the limiting component 7 is different.

[0048] Reference Figure 4 and Figure 5 The limiting component 7 includes a retaining ring 73 and a rotating cylinder 74. The retaining ring 73 is fixedly connected to the inlet tube 11. The inlet tube 11 is provided with a threaded section at the position between the retaining ring 73 and the valve core 2. The rotating cylinder 74 is threaded onto the threaded section, and several abutting flanges 741 are fixedly connected to the inner wall of the rotating cylinder 74.

[0049] When installing the urinary catheter, one end of the urinary catheter is fitted onto the inlet tube 11. Then, the rotating cylinder 74 is rotated. As the rotating cylinder 74 moves, it drives the clamping flange 741 to move. The clamping flange 741 clamps the urinary catheter, causing one end of the urinary catheter to deform, thereby restricting the degree of freedom of the urinary catheter and realizing the installation of the urinary catheter.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
