[0040] Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.
[0041] like Figures 1 to 6As shown, the utility model provides a preferred embodiment of a urinary catheter device with a detachable valve 100 .
[0042] A urinary catheter device with a detachable valve 100, the urinary catheter device includes a tube body 220, and a tube head 210 and a liquid collection bag 230 arranged at both ends of the tube body 220, the tube body 220 includes a first tube body 221 and a second tube body 222, the urinary catheter device also includes a detachable valve 100, the detachable valve 100 includes a first interface 110, a second interface 120, a valve channel 130 and a valve switch 140, the valve channel 130 is connected to the first interface 110 and the second interface 120 respectively, the valve switch 140 is movably arranged in the valve channel 130 to realize the conduction or closing of the first interface 110 and the second interface 120, the first interface 110 can be detachably inserted into the first tube body 221 for sealing connection, and the second interface 120 can be detachably inserted into the first tube body 221 for sealing connection.
[0043] Specifically, the catheter device includes a tube body 220, a tube head 210 and a fluid collection bag 230. The tube body 220 is the main part of the catheter device, which is a hollow pipe structure 1411, used to guide the flow of fluid, and is used to guide fluid, medicine or other substances into or out of the human body. The tube head 210 is a component arranged at both ends of the tube body 220, and is used to be embedded in the human body, such as the brain, to drain cerebrospinal fluid. The fluid collection bag 230 is a part of the catheter device, located at a specific position of the catheter device, and is used to collect and store liquid during the drainage process.
[0044] The tube body 220 of the catheter device is sealedly connected to the first interface 110 and the second interface 120 by the first tube body 221 and the second tube body 222 respectively. The sealed connection can prevent the fluid from leaking or accidentally entering or leaving the catheter device, so that the catheter device and the detachable valve 100 can work together to achieve the control and diversion functions of the fluid. It is not only easy to assemble, but also suitable for conventional catheter devices, providing stable fluid control and diversion performance.
[0045] Among them, reference Figure 6 , Figure 6 Schematic diagram of the connection between the tube head 210, the first tube body 221, the detachable valve 100, the liquid collecting bag 230 and the second tube body 222, wherein the connection direction and position of the above structures are indicated by dotted lines.
[0046] In this embodiment, the valve switch 140 is rotatably arranged in the valve channel 130, and the valve channel 130 is communicated with the first interface 110 and the second interface 120 respectively. The fluid inside the valve channel 130 can flow into the valve channel 130 through the first interface 110, and then flow out from the second interface 120. The first interface 110 and the second interface 120 are connected or closed by the valve switch 140, ensuring that the fluid can flow freely and controllably in the valve channel 130. The valve switch 140 is installed in the valve channel 130 and can be rotated therein. The rotation of the valve switch 140 can realize the connection or closing of the first interface 110 and the second interface 120. When the valve switch 140 is in the on state, the fluid can flow from the first interface 110 to the second interface 120 through the valve channel 130, or from the second interface 120 to the first interface 110. When the valve switch 140 is in the off state, the valve channel 130 will prevent the passage of the fluid, thereby realizing the closing of the first interface 110 and the second interface 120.
[0047] In this embodiment, reference 2 to Figure 4 The valve channel 130 includes a rotating cavity 131, on which a top opening 1311 is provided, as well as a first port 1312 and a second port 1313 provided on the side. The first port 1312 is communicated with the first interface 110, and the second port 1313 is communicated with the second interface 120. The valve switch 140 includes a conducting channel 141, and the valve switch 140 is rotatably provided in the rotating cavity 131 through the top opening 1311, so that the conducting channel 141 rotates in the rotating cavity 131, and the conducting channel 141 is connected to the first port 1312 and the second port 1313 when rotating to the conducting direction.
[0048] Specifically, the valve channel 130 includes a rotating cavity 131, a first port 1312 is connected to the first interface 110, and a second port 1313 is connected to the second interface 120. The valve channel 130 can realize the conduction of the fluid between the first interface 110 and the second interface 120. The valve switch 140 includes a conduction channel 141. The valve switch 140 passes through the top opening 1311 and is inserted into the rotating cavity 131 to rotate. Through the rotation of the valve switch 140, the conduction channel 141 rotates in the rotating cavity 131. When the conduction channel 141 rotates to the conduction direction, the conduction channel 141 will communicate with the first port 1312 and the second port 1313, thereby realizing the conduction between the first interface 110 and the second interface 120. Through the rotation of the valve switch 140, the conduction channel 141 can switch the conduction direction or the closed state in the rotating cavity 131, thereby controlling the flow direction and conduction of the fluid.
[0049] By rotating the valve switch 140, the conducting direction or the closing state of the conducting channel 141 can be changed, and the flow direction of the fluid can be conveniently controlled, so that the fluid flows from the first interface 110 to the second interface 120 or from the second interface 120 to the first interface 110, and the flow direction is controlled according to actual needs. In addition, the overall structure is relatively simple, the assembly is simple and fast, and the cost is low.
[0050] It can also provide reliable sealing performance to ensure that the fluid will not leak or accidentally enter or leave the valve channel 130, ensuring the reliable operation of the system. The design of the rotating cavity 131 of the valve channel 130 and the valve switch 140 makes the entire device structurally stable and able to withstand higher pressures, making the device suitable for various drainage application scenarios that require control of flow and flow direction.
[0051] In this embodiment, reference Figure 7 The first opening 1312 or the second opening 1313 is provided with a flow blocking structure 132. The flow blocking structure 132 is preferably a semicircular baffle 145 provided at the first opening 1312 or the second opening 1313, so that the circular through hole of the first opening 1312 or the second opening 1313 forms a semicircular through hole, and the provision of the semicircular baffle 145 can effectively limit the flow of the fluid.
[0052] The flow-blocking structure 132 includes a block disposed near the first opening 1312 , and the block forms an inclined wedge-shaped structure toward the inside of the first interface 110 , so as to make the liquid flow more smoothly and also have a flow-blocking effect.
[0053] like Figure 7 and Figure 8 As shown, the present invention provides a preferred embodiment of the raised cylinder 142 .
[0054] The valve switch 140 includes a protruding cylinder 142 rotatably set in the rotating cavity 131, and a through hole is set on the protruding cylinder 142 as a conducting channel 141. When the protruding cylinder 142 is rotated to the conducting direction, the two ends of the conducting channel 141 are aligned with the first opening 1312 and the second opening 1313 respectively; when the protruding cylinder 142 is rotated to the non-conducting direction, the side of the protruding cylinder 142 closes the first opening 1312 and the second opening 1313; wherein, the outer surface of the protruding cylinder 142 is arranged to be interference fit with the inner surface of the rotating cavity 131.
[0055] Specifically, the raised cylinder 142 is arranged in the rotating cavity 131, and the outer surface of the raised cylinder 142 is interference fit with the inner surface of the rotating cavity 131. The contact between the outer surface of the raised cylinder 142 and the inner surface of the rotating cavity 131 is very close, ensuring the sealing performance and structural stability, while also achieving the effect of rotational positioning to prevent changes in conduction or closing caused by misoperation.
[0056] The protruding cylinder 142 is provided with a through hole serving as the conducting channel 141. When the protruding cylinder 142 rotates to the conducting direction, the two ends of the conducting channel 141 are respectively aligned with the first port 1312 and the second port 1313, so that the fluid can flow from the first interface 110 to the second interface 120, or from the second interface 120 to the first interface 110. When the protruding cylinder 142 rotates to the non-conducting direction, strictly speaking, the direction includes the angle of partial conduction and closing, and the closing angle is the non-conducting direction. The side of the protruding cylinder 142 closes the first port 1312 and the second port 1313, preventing the passage of the fluid, realizing the closing of the valve channel 130, and controlling the conducting direction or closing state of the conducting channel 141, thereby accurately, conveniently and quickly controlling the flow direction and conduction of the fluid.
[0057] By rotating the raised cylinder 142, the two ends of the conduction channel 141 can be aligned with the first port 1312 and the second port 1313 respectively, so that the fluid can be conducted. When the raised cylinder 142 is rotated to the non-conducting direction, the side of the raised cylinder 142 closes the first port 1312 and the second port 1313, and the valve channel 130 is closed, which can accurately control the conduction and closure of the fluid and realize the control function of the fluid. The outer surface of the raised cylinder 142 and the inner surface of the rotating cavity 131 are arranged in an interference fit to ensure the sealing performance and structural stability. The interference fit can provide a closer contact to prevent the fluid from leaking or accidentally entering or leaving the valve channel 130, and also enhance the structural stability of the entire device. Through the rotation of the raised cylinder 142, the conduction and closure of the fluid can be achieved, and the operation is simple, providing reliable fluid control, so that the fluid can flow or stop as needed, meeting the needs of different application scenarios. Due to the interference fit between the raised cylinder 142 and the rotating cavity 131 and the stability of the entire structure, the valve switch 140 is designed to have high durability and pressure resistance, can withstand high pressure, and is suitable for various drainage application scenarios that require control of flow and flow direction.
[0058] In this embodiment, reference Figures 9 to 11 The raised cylinder 142 is a hollow structure 1421 , and the conducting channel 141 is a pipe structure 1411 penetrating into the hollow structure 1421 of the raised cylinder 142 . The raised cylinder 142 also includes a reinforcing rib structure connected to the surface of the pipe structure 1411 .
[0059] The raised cylinder 142 is hollow, that is, the interior is hollow, and can accommodate the conductive channel 141 and provide a channel when the fluid flows through. The raised cylinder 142 also includes a reinforcing rib structure connected to the surface of the pipeline structure 1411. The function of the reinforcing rib structure is to enhance the strength and stability of the raised cylinder 142 and the pipeline structure 1411 so that they can withstand fluid pressure and external stress.
[0060] Furthermore, the reinforcing rib structure includes a transverse reinforcing plate 1432 and a vertical reinforcing plate 1431. The transverse reinforcing plate 1432 and the conducting channel 141 can also achieve longitudinal sealing of the hollow structure 1421. The transverse reinforcing plate 1432 in the reinforcing rib structure is located in the transverse direction of the protruding cylinder 142, adjacent to the conducting channel 141, and the function of the transverse reinforcing plate 1432 is to increase the transverse strength of the protruding cylinder 142 so that it can withstand external stress and pressure. The vertical reinforcing plate 1431 in the reinforcing rib structure is located in the vertical direction of the protruding cylinder 142, adjacent to the conducting channel 141, and the function of the vertical reinforcing plate 1431 is to increase the vertical strength of the protruding cylinder 142 so that it can withstand external stress and pressure. A longitudinal seal is formed between the transverse reinforcing plate 1432 and the conducting channel 141, and between the vertical reinforcing plate 1431 and the conducting channel 141. The contact between the transverse reinforcing plate 1432 and the vertical reinforcing plate 1431 and the conducting channel 141 forms a sealing structure to prevent fluid leakage or inadvertent entry or exit of the hollow structure 1421.
[0061] Among them, the transverse reinforcement plate 1432 and the vertical reinforcement plate 1431 are vertically arranged to form a cross reinforcement structure, which provides additional strength and stability, allowing the raised cylinder 142 to withstand greater pressure and stress, effectively increasing the strength and stability of the raised cylinder 142.
[0062] In this embodiment, and with reference to Fig.12 The rotating cavity 131 includes a circular groove 1314 arranged at the edge, and the edge of the protruding cylinder 142 is inserted into the circular groove 1314 .
[0063] The circular groove 1314 is a structure at the bottom edge of the rotating cavity 131, and it has a ring shape. The edge of the raised cylinder 142 is also a ring structure, and its edge portion can be stuck in the circular groove 1314. The circular groove 1314 provides a fixed track, so that the raised cylinder 142 can rotate along the periphery of the groove, thereby achieving accurate control of the valve switch 140; and, through the cooperation of the raised cylinder 142 and the circular groove 1314, an annular sealing contact surface is formed, which can effectively prevent fluid leakage or external impurities from entering the rotating cavity 131.
[0064] In this embodiment, the center of the pipe structure 1411 is arranged laterally in the hollow structure 1421 of the raised cylinder 142. The cross-sectional area of the hollow structure 1421 is large, while the cross-sectional area of the pipe structure 1411 is small. If the pipe structure 1411 is directly arranged laterally in the middle of the hollow structure 1421, both sides of the pipe structure 1411 will be hollowed out without support, and even if the reinforcement structure is added, the overall hardness will be low. Therefore, the center of the pipe structure 1411 is arranged laterally in the hollow structure 1421, so that part of the outer edge of the pipe structure 1411 fits with the inner wall of the hollow structure 1421 to form a stronger support structure.
[0065] like Fig.13 and Fig.14 As shown, the present invention provides a preferred embodiment of the raised cylinder 142 .
[0066] The valve switch 140 includes a handle, which includes an extension portion 144 and a baffle 145. The valve switch 140 includes a top turntable 1401. The extension portion 144 is connected to the top turntable 1401, and the extension portion 144 includes a first edge 1441 and a second edge 1442 arranged along the tangent direction of the circle of the top turntable 1401. The first edge 1441 and the second edge 1442 intersect away from the top turntable 1401 to form the extension portion 144; and the baffle 145 is respectively arranged parallel to the first edge 1441 and the rotation axis of the top turntable 1401, and is extended downward; wherein, when the baffle 145 is close to the first interface 110, the first interface 110 and the second interface 120 are connected, and when the baffle 145 is close to the second interface 120, the first interface 110 and the second interface 120 are closed.
[0067] When the baffle 145 is rotated to the extreme position, it is set close to the first interface 110 and the second interface 120. On the one hand, the baffle 145 can limit the position. On this basis, the rotation range of the handle is maximized. When the baffle 145 is turned on, it is set close to the first interface 110. When the baffle 145 is turned off, the openings at both ends of the conducting channel 141 are far enough away from the first opening 1312 and the second opening 1313, thereby improving the sealing performance in the closed state.
[0068] In this embodiment, a first magnetic structure is provided on the baffle 145, and a second magnetic structure and a third magnetic structure are respectively provided at corresponding positions of the first interface 110 and the second interface 120. The baffle 145 is magnetically attracted to the second magnetic structure or the third magnetic structure through the first magnetic structure, thereby positioning the baffle 145 to the first interface 110 or the second interface 120.
[0069] Through the magnetic adsorption effect, the baffle 145 can be accurately positioned at the position of the first interface 110 or the second interface 120, which is simpler than other complex positioning mechanisms and also reduces the possibility of malfunction and failure. In the on state, the baffle 145 is close to the first interface 110, and the magnetic adsorption force keeps the baffle 145 in contact with the second magnetic structure, thereby ensuring the sealing performance of the conduction channel 141; in the off state, the baffle 145 is close to the second interface 120, and the magnetic adsorption force keeps the baffle 145 in contact with the third magnetic structure, thereby ensuring the sealing performance in the off state.
[0070] Among them, a magnet installation space can be reserved on the baffle 145 and the interface so that the magnet can be embedded therein and adsorbed with the baffle 145, and a suitable fixing device, such as screws or glue, can be used to fix the magnet on the baffle 145 or the interface. Preferably, the magnetic attraction structure is wrapped during integral injection molding.
[0071] like Fig.15 As shown, the present invention provides a preferred embodiment of the raised cylinder 142 .
[0072] The outer surfaces of the first interface 110 and the second interface 120 are both provided with a sealing structure, which includes a first annular step block 111 arranged on the outside, and a second annular step block 112 arranged on the inside; wherein, the step surface of the first annular step block 111 is arranged to face inwards, serving as a seal; and the step surface of the second annular step block 112 is arranged to face outwards, serving as a limiter.
[0073] The first annular terrace block 111 is located outside the sealing structure, and its terrace surface is arranged to face inward. As a sealing member, the plane of the first annular terrace block 111 faces inward, and can provide a sealing effect when in contact with the tube body 220. The shape and size of the first annular terrace block 111 should match the design of the tube body 220 to ensure effective sealing performance. Of course, multiple first annular terrace blocks 111 are provided, and the tube body 220 is provided with an internal structure that matches the appearance of the first annular terrace block 111 to achieve a structural matching setting.
[0074] At the same time, the tube body 220 is effectively prevented from being reversely separated from the first interface 110 .
[0075] By using the first annular step block 111 as a seal and the second annular step block 112 as a stopper, the dual functions of the interface can be achieved. The sealing function of the first annular step block 111 can ensure that when the device is closed, the sealing performance between the tube body 220 and the interface is good, preventing liquid or gas leakage and detachment. The stopper function of the second annular step block 112 can ensure that when the device is open, the relative position between the interfaces is fixed, avoiding excessive rotation or movement between the interface and the tube.
[0076] like Figures 16 to 18 As shown, the utility model provides another preferred embodiment of the valve channel.
[0077] The valve channel 130 includes a sliding cavity 1301, and the valve switch includes a first limiting portion 310, a first sliding portion 320, a connecting portion 330, a second sliding portion 340 and a second limiting portion 350 which are arranged in sequence. The first sliding portion 320 and the second sliding portion 340 are connected by the connecting portion 330 and are slidably arranged in the sliding cavity 1301. When the valve switch slides to the first position, the first limiting portion 310 presses against the end of the sliding cavity 1301, and the first sliding portion 320 blocks the first interface 110 and the second interface 120 to achieve the closure of the first interface 110 and the second interface 120; and when the valve switch slides to the second position, the second limiting portion 350 presses against the end of the sliding cavity 1301, and the first sliding portion 320 blocks the first interface 110 and the second interface 120 to achieve the closure of the first interface 110 and the second interface 120.
[0078] Among them, the first position reference Fig.16 , the second position reference Fig.17 , thereby achieving the communication and closing of the first opening 1312 and the second opening 1313.
[0079] Specifically, the valve channel 130 includes a sliding cavity 1301 for accommodating the sliding movement of the valve switch. The valve switch includes a first limiter 310, a first sliding portion 320, a connecting portion 330, a second sliding portion 340 and a second limiter 350 arranged in sequence, and the first sliding portion 320 and the second sliding portion 340 are connected by the connecting portion 330 and slide in the sliding cavity 1301. When the valve switch slides to the first position, the first limiter 310 abuts against the end of the sliding cavity 1301, and the first sliding portion 320 shields the first interface 110 and the second interface 120, thereby closing the first interface 110 and the second interface 120. When the valve switch slides to the second position, the second limiter 350 abuts against the end of the sliding cavity 1301, and the first sliding portion 320 shields the first interface 110 and the second interface 120, thereby closing the first interface 110 and the second interface 120. The first interface 110 and the second interface 120 can be opened or closed by sliding the valve switch in the sliding cavity 1301, thereby controlling the liquid flow of the catheter device, so that the valve can be easily disassembled and installed for cleaning and maintenance of the catheter device.
[0080] When the valve switch is in the first position, the first limiter 310 contacts the end of the sliding cavity 1301, preventing the valve switch from sliding forward. At the same time, the first sliding portion 320 is located in the sliding cavity 1301, shielding the first interface 110 and the second interface 120, preventing urine from flowing through the valve channel 130, and realizing the closed state of the first interface 110 and the second interface 120. When the valve switch slides to the second position, the second limiter 350 contacts the end of the sliding cavity 1301, preventing the valve switch from sliding backward. At the same time, the first sliding portion 320 is still located in the sliding cavity 1301, shielding the first interface 110 and the second interface 120, preventing urine from flowing through the valve channel 130, and still realizing the closed state of the first interface 110 and the second interface 120. Through the sliding of the valve switch in the sliding cavity 1301, the opening and closing states of the valve can be flexibly controlled, thereby controlling the flow of urine, which is operable and controllable, and the user can adjust the position of the valve as needed to meet individual needs.
[0081] In this embodiment, the sliding cavity 1301 includes a first port 133 and a second port arranged on both sides, the total distance of the cross section formed by the first interface 110 and the second interface 120 is set to D1, the longitudinal distance between the first port 133 and the edge of the first interface 110 or the second interface 120 is set to D2, the longitudinal distance between the second port and the other edge of the first interface 110 or the second interface 120 is set to D3, the length of the first sliding part 320 is set to D4, the length of the second sliding part 340 is set to D5, the D4 is not less than D2+D1, and the D5 is close to or equal to D3+D1.
[0082] The sliding cavity 1301 is a cylindrical cavity, and the first port 133 and the second port 134 are respectively provided on the upper and lower end surfaces. The first sliding part 320, the connecting part 330, and the second sliding part 340 of the valve switch slide up and down in the cylindrical cavity, and the first sliding part 320 and the second sliding part 340 can be extended into the cylindrical cavity, and can be moved outward from the first port 133 and the second port 134 respectively, and the sliding limit is realized by the first limit part 310 and the second limit part 350 at both ends. The connecting part 330 is a connecting column connecting the first sliding part 320 and the second sliding part 340. The cross-sectional area of the connecting part 330 is smaller than the cross-sectional area of the first sliding part 320 and the second sliding part 340, and can be used as a circulation channel, while the cross-sectional area of the first sliding part 320 and the second sliding part 340 is similar to the cross-sectional area of the cylindrical cavity, and is preferably an interference fit to achieve sealing.
[0083] The size is set so that the sliding cavity 1301 can accommodate the sliding of the valve switch and ensure that the first sliding part 320 and the second sliding part 340 have sufficient length in the sliding cavity 1301 to cover the first interface 110 and the second interface 120, realize the closed state of the valve, ensure the stability and sealing of the valve, and effectively control the flow of urine. The valve switch can move freely in the sliding cavity 1301 and is limited by the first limiting part 310 and the second limiting part 350. The small cross-sectional area of the connecting part 330 allows the fluid to pass through, and the interference fit of the first sliding part 320 and the second sliding part 340 ensures the sealing of the valve, so that the valve switch can move flexibly in the cylindrical cavity and can realize the opening and closing of the valve to control the flow of urine.
[0084] In this embodiment, the first limiting portion 310, the first sliding portion 320, the connecting portion 330 and the second sliding portion 340 are integrally formed, and the second limiting portion 350 is fixed to the second sliding portion 340; or, the first sliding portion 320, the connecting portion 330, the second sliding portion 340 and the second limiting portion 350 are integrally formed, and the first limiting portion 310 and the first sliding portion 320 are fixed.
[0085] Specifically, a groove is provided at the end of the second sliding part 340, and the second limiting part 350 is inserted into the groove to achieve a fixed connection, so that the second sliding part 340 is inserted into the sliding cavity 1301 from the first port 133, and then the second limiting part 350 is installed to achieve the installation of the valve switch. Similarly, a groove may be provided at the end of the first sliding part 320, and the first limiting part 310 is inserted into the groove to achieve a fixed connection, so that the first sliding part 320 is inserted into the sliding cavity 1301 from the second port 134, and then the first limiting part 310 is installed to achieve the installation of the valve switch.
[0086] The above is only the best embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes or modifications made within the scope of the patent application of the present invention are covered by the present invention.
