Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ureteral catheter connection equipment, in particular to a connection device for quick plugging and unplugging of a non-integrated ureteral catheter. Background Art
[0002] There are currently two commonly used ureteral catheters. One is an integrated ureteral catheter, which has its own connecting device, but it cannot be disassembled for use. This device is not convenient for intubation of the ureteral catheter under ureteroscopy. During intubation under the microscope, the end connecting device itself cannot pass through the ureteroscope, and intubation and withdrawal of the scope cannot be performed at the same time; the other non-integrated ureteral catheter is convenient for intubation under ureteroscopy, and intubation and withdrawal of the scope can be performed at the same time, but it has no connecting device, so after intubation, a self-made connecting catheter or a syringe needle needs to be added before use, which is inconvenient for clinical operation. For this reason, we propose a connecting device for quick insertion and removal of non-integrated ureteral catheters. Utility Model Content
[0003] The purpose of the present utility model is to provide a connection device for quick plugging and unplugging of a non-integrated ureteral catheter, so as to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a connection device for quick plugging and unplugging of a non-integrated ureteral catheter, comprising an outer sleeve, wherein the right side and the interior of the outer sleeve are provided with a connection portion for quick connection of the ureteral catheter, wherein the connection portion comprises: a plug connector, wherein the plug connector is fixed to the right side of the outer sleeve, and a hollow silicone hard tube and an elastic rubber tube are fixed to the inner wall of the outer sleeve. When connecting the ureteral catheter, it is only necessary to insert the ureteral catheter from the plug connector and then insert the ureteral catheter into the elastic rubber tube. Since the diameter of the elastic rubber tube is slightly smaller than that of the ureteral catheter, when the ureteral catheter is inserted, the elastic rubber tube is squeezed to expand. The ureteral catheter is squeezed by the elastic action of the elastic rubber tube itself, thereby achieving fixation and facilitating the insertion of the ureteral catheter.
[0005] Preferably, the right end of the elastic rubber tube and the plug joint are both trumpet-shaped, the left end of the elastic rubber tube is fixed to the right end of the hollow silicone hard tube, and the left end of the hollow silicone hard tube is fixed to the outer sleeve. The right end of the elastic rubber tube and the plug joint are trumpet-shaped, and the right side of the elastic rubber tube is closed to the inner wall of the outer sleeve to form a funnel shape. The ureteral catheter can be fixed when inserted, so that it can be quickly plugged in and out.
[0006] Preferably, the left side of the outer sleeve is threadedly connected to a heparin cap. When not in use, the outer sleeve can be sealed by the heparin cap to prevent urine leakage and affect surgical operations. When injecting, only the heparin cap needs to be unscrewed to connect the syringe, which is convenient and quick.
[0007] Preferably, the surface of the outer sleeve is provided with external threads, which facilitates direct connection to a syringe.
[0008] Preferably, the surface of the outer sleeve is provided with annular teeth to facilitate fixation of the entire device and clinical operation.
[0009] Compared with the prior art, the present invention provides a connection device for quick plugging and unplugging of a non-integrated ureteral catheter, which has the following beneficial effects:
[0010] 1. This connection device for quick plug-in and plug-out of a non-integrated ureteral catheter has a connection portion. When connecting the ureteral catheter, it is only necessary to insert the ureteral catheter from the plug connector and then insert the ureteral catheter into the elastic rubber tube. Since the diameter of the elastic rubber tube is slightly smaller than the ureteral catheter, when the ureteral catheter is inserted, the elastic rubber tube is squeezed to expand. The elastic action of the elastic rubber tube itself squeezes the ureteral catheter, thereby achieving fixation and facilitating the insertion of the ureteral catheter.
[0011] 2. This connection device for quick insertion and removal of non-integrated ureteral catheters can seal the outer sleeve with a heparin cap when not in use to prevent urine leakage and affect surgical operations. During injection, the syringe can be connected by simply unscrewing the heparin cap, which is convenient and quick. The annular teeth provided on the surface of the outer sleeve facilitate the fixation of the entire device and clinical operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1-Figure 3As shown, the utility model provides a technical solution: a connection device for quick plugging and unplugging of a non-integrated ureteral catheter, comprising an outer sleeve 1, a connection part 2 for quick connection of the ureteral catheter is provided on the right side and inside of the outer sleeve 1, the connection part 2 comprises: a plug connector 21, the plug connector 21 is fixed to the right side of the outer sleeve 1, a hollow silicone hard tube 22 and an elastic rubber tube 23 are fixed to the inner wall of the outer sleeve 1, when connecting the ureteral catheter, it is only necessary to insert the ureteral catheter from the plug connector 21, and insert the ureteral catheter into the elastic rubber tube 23 through the ureteral catheter. Since the diameter of the elastic rubber tube 23 is slightly smaller than the ureteral catheter, when the ureteral catheter is inserted, the elastic rubber tube 23 is squeezed to expand it, and the ureteral catheter is squeezed by the elastic action of the elastic rubber tube 23 itself, thereby achieving fixation, which facilitates the insertion of the ureteral catheter.
[0017] The right end of the elastic rubber tube 23 and the plug connector 21 are both trumpet-shaped, the left end of the elastic rubber tube 23 is fixed to the right end of the hollow silicone hard tube 22, and the left end of the hollow silicone hard tube 22 is fixed to the outer sleeve 1. The right end of the elastic rubber tube 23 and the plug connector 21 are trumpet-shaped, and the right side of the elastic rubber tube 23 is closed to the inner wall of the outer sleeve 1 to form a funnel shape. The ureteral catheter can be fixed when inserted, and can be quickly plugged and unplugged.
[0018] The left side of the outer sleeve 1 is threadedly connected to a heparin cap 3. When not in use, the outer sleeve 1 can be sealed by the heparin cap 3 to prevent urine leakage and affect surgical operations. When injecting, you only need to unscrew the heparin cap 3 to connect the syringe, which is convenient and quick. The surface of the outer sleeve 1 is provided with an external thread 4, which is convenient for direct connection to the syringe. The surface of the outer sleeve 1 is provided with annular teeth, which is convenient for fixing the entire device and clinical operation.
[0019] Based on the above embodiment, when in use, the ureteral catheter is inserted from the plug connector 21 and then inserted into the elastic rubber tube 23. Since the diameter of the elastic rubber tube 23 is slightly smaller than the ureteral catheter, the elastic rubber tube 23 is squeezed after the ureteral catheter is inserted, causing it to expand. The elastic rubber tube 23 squeezes the ureteral catheter under its own elastic action, thereby achieving fixation, facilitating the insertion of the ureteral catheter. Only a disposable adhesive is needed to restrict the catheter.
[0020] The injection operation can be performed by connecting the syringe to the outer sleeve 1. When not in use, the heparin cap 3 is connected to the outer sleeve 1 to achieve blocking to prevent urine leakage and affect the surgical operation.
[0021] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
