Description

Technical Field

[0001] This utility model relates to the field of pet urinary catheter technology, specifically to a leak-proof pet urinary catheter. Background Technology

[0002] Pet urinary catheters are commonly used to help pets collect urine or to help pets with limited mobility, such as those recovering from surgery, urinate. These catheters typically consist of a tube and a connector. The tube is inserted into the bladder through the pet's urethra to drain urine. Currently, medication administration and flushing of urinary catheters are accomplished through the catheter connector. When administering medication, the infusion tube is connected to the catheter connector for slow administration. During flushing, a syringe is used to flush the tubing and urethra by applying pressure through the flushing connector. However, existing catheter connectors and syringes are not perfectly matched, resulting in a large gap. This not only makes positioning and operation inconvenient but also easily leads to leakage, infection, and poor efficacy. Utility Model Content

[0003] The purpose of this invention is to provide a leak-proof pet urinary catheter. By setting a connector with a tapered channel on the catheter body, the tapered channel adopts a standard 6:100 taper design with the same tip of the syringe, which can seal and cooperate with the syringe, resulting in good sealing and leak-proof performance, reducing the risk of infection. At the same time, it is simple for doctors to operate and convenient for doctors to position and operate, thus solving the above-mentioned shortcomings in the technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof pet urinary catheter, comprising:

[0005] The catheter body has a connector at its head and a catheter port at its tail. One end of the connector is detachably connected to a connector, and the connector has a tapered channel inside.

[0006] The positioning seat is located at one end of the connector relative to the connecting seat. The positioning seat has multiple cavities arranged in a ring array between its inner and outer sides. A spring is fixed to one end of each cavity. A slider is connected to one end of the spring. A connecting rod is provided at the end of the slider relative to the spring. A silicone ring is connected to one end of the connecting rod that extends into the interior of the positioning seat.

[0007] Preferably, the side end of the silicone ring is provided with a rounded chamfer.

[0008] Preferably, the port of the positioning seat is equipped with a connecting cap, the inner side of the connecting cap is provided with an internal thread, and the outer side of the positioning seat is provided with an external thread that matches the internal thread.

[0009] Preferably, the port of the positioning seat has a tapered opening on the side near the silicone ring, and the inner side of the connecting cap has a plug that matches the tapered opening.

[0010] Preferably, the end of the connector near the connecting seat is provided with an internally threaded connecting cylinder, and the end of the connecting seat is provided with an externally threaded connecting pipe that matches the internally threaded connecting cylinder.

[0011] Preferably, a suture ring is provided on the outer side of the connecting seat, and the side wall of the suture ring is provided with multiple suture grooves.

[0012] Preferably, a guide wire is inserted between the catheter body and the connector.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By setting a connector with a tapered channel on the catheter body, the tapered channel adopts the same 6:100 taper design as the front end of the syringe, which can seal with the syringe, resulting in good sealing and leak prevention, reducing the risk of infection. At the same time, it is simple for doctors to operate and facilitates positioning.

[0015] By setting a positioning seat on the connector, the positioning seat has multiple sets of silicone rings, connecting rods and springs arranged in a ring array. When the front end of the syringe is mated with the tapered channel, the multiple silicone rings can wrap and press the end of the syringe tightly, thereby limiting and reinforcing the front end of the syringe to prevent the front end from loosening and separating to create gaps. This further enhances the sealing performance and greatly improves the effectiveness of the device.

[0016] By setting a connecting cap at the port of the positioning seat, and with the cooperation of internal threads, external threads, a plug and a tapered opening, the connecting cap can tightly seal the positioning seat. Furthermore, by setting an internal threaded connecting sleeve and an external threaded connecting tube, quick assembly and disassembly between the connector and the catheter body can be achieved, thus making it easier for doctors to operate and use the device.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figures 1-7 The leak-proof pet urinary catheter shown includes:

[0029] The catheter body 1 has a connector 3 at its head and a catheter port 2 at its tail. One end of the connector 3 is detachably connected to a connector 7, and the connector 7 has a tapered channel 8 inside.

[0030] The connector 7 is provided with an internally threaded connecting sleeve 6 at one end near the connecting seat 3, and the end of the connecting seat 3 is provided with an externally threaded connecting pipe 5 that matches the internally threaded connecting sleeve 6.

[0031] A suture ring 4 is provided on the outer side of the connector 3, and the side wall of the suture ring 4 has multiple suture grooves. By using sutures to sew the suture ring 4 to the pet's wound, it can fix the urinary catheter and prevent it from falling out.

[0032] A guide wire 9 is inserted between the catheter body 1 and the connecting seat 3.

[0033] The positioning seat 10 is located at one end of the connector 7 relative to the connecting seat 3. The inner and outer sides of the positioning seat 10 are provided with multiple cavities 11 in a ring array. A spring 12 is fixed to one end of each cavity 11. A slider 13 is connected to one end of the spring 12. A connecting rod 14 is provided at one end of the slider 13 relative to the spring 12. A silicone ring 15 is connected to one end of the connecting rod 14 that extends into the interior of the positioning seat 10.

[0034] The side end of the silicone ring 15 is provided with a rounded chamfer. The rounded chamfer facilitates the insertion of the syringe syringe into the space between multiple silicone rings 15.

[0035] By setting the connector 7, a tapered channel 8 is provided inside the connector 7.

[0036] Furthermore, by setting the positioning seat 10, when the syringe is mated with the tapered channel 8 on the connector 7, the end of the syringe can first be squeezed between multiple annularly distributed silicone rings 15, causing the silicone rings 15 to drive the connecting rod 14 to move. The connecting rod 14 can drive the slider 13 to slide in the cavity 11 and squeeze the spring 12. When the front end of the syringe is fully abutted against the tapered channel 8, under the elastic compensation of the spring 12, the multiple silicone rings 15 can wrap and press the end of the syringe tightly, thereby limiting and reinforcing the front end of the syringe to prevent the front end from loosening and separating to create gaps, thereby further enhancing the sealing performance and greatly improving the use effect of the device.

[0037] The port of the positioning seat 10 is equipped with a connecting cap 16. The inner side of the connecting cap 16 is provided with an internal thread 17, and the outer side of the positioning seat 10 is provided with an external thread 18 that matches the internal thread 17.

[0038] The positioning seat 10 has a tapered opening 20 on the side of the port near the silicone ring 15, and the inner side of the connecting cap 16 has a plug 19 that matches the tapered opening 20.

[0039] The connection is achieved by screwing the internal thread 17 with the external thread 18, and the plug 19 is inserted into the conical opening 20, thereby achieving a tight seal between the connecting cap 16 and the positioning seat 10.

[0040] Furthermore, by screwing the internal threaded connecting sleeve 6 and the external threaded connecting tube 5 together, the connector 7 and the catheter body 1 can be quickly assembled and disassembled, which makes it easier for doctors to operate and use the device.
