Abstract
Description
Technical Field
[0001] This application relates to the technical field of jigs, and more specifically, it relates to a catheter structure assembly jig. Background Art
[0002] The catheter structure is mainly used for catheterization of patients with inconvenient urination. The patient's urine is introduced into the urine bag through the catheter structure. Referring to Figure 1 , the catheter structure 100 includes a rubber sleeve 101 connected to the human body, a soft rubber tube 102 for guiding the flow, a rubber joint tube 103 for connecting to the urine bag, and two cylindrical metal tubes 104 for sealed connection. The soft rubber tube 102 is a heat-shrinkable tube. When assembling the catheter structure 100, it is usually formed by manual assembly with both hands. Specifically, one end of the heat-shrinkable tube is sleeved on a cylindrical metal tube 104 and heated with a heat gun so that this end of the heat-shrinkable tube fits against the outer wall of the cylindrical metal tube 104. Then, the other end of the heat-shrinkable tube is sleeved on another cylindrical metal tube 104 and heated with a heat gun so that this end of the heat-shrinkable tube fits against the outer wall of this cylindrical metal tube 104. Then, the rubber sleeve 101 is sleeved into a cylindrical metal tube 104 and fixed with glue to seal and connect the rubber sleeve 101 with this cylindrical metal tube 104 and one end of the heat-shrinkable tube. And the joint tube 103 is sleeved into another cylindrical metal tube 104 and fixed with glue to seal and connect the joint tube 103 with this cylindrical metal tube 104 and the heat-shrinkable tube. An abutting block is provided in the inner hole of the rubber sleeve 101 and the inner hole of the joint tube 103. The penetration depth of the cylindrical metal tube 104 is positioned by abutting the abutting block against the cylindrical metal tube 104. The glue used is UV curable glue, and finally the glue is cured by a UV lamp to obtain the finished product.
[0003] Adopting the above technical solution, when assembling the cylindrical metal tube and the heat-shrinkable tube, both the cylindrical metal tube and the heat-shrinkable tube need to be manually positioned by hand. When assembling the rubber sleeve and the joint tube with the cylindrical metal tube, manual support is also required. Assembling only with both hands is rather inconvenient, and the assembly efficiency of the catheter structure is relatively low. Utility Model Content
[0004] In order to solve the problem that in the related technology, assembling the catheter structure only with both hands is rather inconvenient and the assembly efficiency of the catheter structure is relatively low, this application provides a catheter structure assembly jig.
[0005] A catheter structure assembly jig, comprising a counterweight seat and an assembly rod. Two cylindrical platforms are formed in the middle of the assembly rod. The two cylindrical platforms are arranged at intervals along the length direction of the assembly rod, and annular grooves are recessed on the outer walls of the two cylindrical platforms. Rubber rings are installed in the annular grooves in a limited manner, and the rubber rings protrude from the annular grooves. A limiting groove matching the assembly rod is recessed downward from the top of the counterweight seat, and one end of the assembly rod is inserted into the limiting groove to be fixed.
[0006] Preferably, the counterweight seat includes a heavy object block providing weight and a rubber sleeve support block for supporting the rubber sleeve. The rubber sleeve support block is fixed to the top surface of the heavy object block by bolts. A receiving groove matching the outer peripheral shape of the rubber sleeve is recessed on the top surface of the rubber sleeve support block. A convex column matching the inner hole of the rubber sleeve is arranged in the middle of the receiving groove, and the limiting groove is arranged in the middle of the convex column.
[0007] Preferably, the heavy object block is an iron block.
[0008] Preferably, the number of annular grooves recessed in the two cylindrical platforms is two, and the number of rubber rings matches the number of annular grooves.
[0009] The beneficial technical effects of this application are as follows:
[0010] Two cylindrical metal tubes are respectively sleeved on the two cylindrical platforms. The rubber rings are tensioned to fix the cylindrical metal tubes at intervals on the assembly rod. The assembly rod is inserted into the limiting groove and erected to be limited and fixed by the counterweight block. By setting the distance between the cylindrical platforms to match the length of the heat shrinkable tube, when fixing the cylindrical metal tubes, the two cylindrical tubes are made to match the length of the heat shrinkable tube. The heat shrinkable tube is sleeved on the assembly rod, with one end of the heat shrinkable tube sleeved on the outer wall of one cylindrical metal tube and the other end sleeved on the outer wall of the other cylindrical metal tube. Squeezing the heat shrinkable tube positions the heat shrinkable tube with the two cylindrical metal tubes, making the combination of the heat shrinkable tube and the cylindrical metal tubes easier and more convenient. By placing the rubber sleeve on the counterweight seat, the assembly rod passes through the inner hole of the rubber sleeve and then into the limiting groove. By reasonably setting the position of the cylindrical platform, one cylindrical metal tube passes through the inner hole of the rubber sleeve and just abuts against the abutting block. By sleeving the joint on the assembly rod, the abutting block in the inner hole of the joint tube abuts against the top surface of the upper cylindrical metal tube to support the joint tube. The rubber sleeve and the joint tube are supported and positioned, facilitating glue dispensing and UV curing operations. With the assistance of the assembly jig of this application for positioning and supporting each component, the assembly efficiency of the urinary catheter structure is higher.

Detailed implementation manners
[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0015] Refer to Figure 2 , a catheter structure assembly fixture, including a counterweight seat 1 and an assembly rod 2. The counterweight seat 1 includes a heavy object block 11 and a rubber sleeve support block 12. The rubber sleeve support block 12 is fixed to the top surface of the heavy object block 11 by bolts. And a accommodation groove 121 matching the outer peripheral shape of the rubber sleeve is concavely provided on the bottom surface of the rubber sleeve support block 12. A convex column 122 matching the inner hole of the rubber sleeve is provided in the middle of the accommodation groove 121. A limit groove 123 matching the assembly rod 2 is concavely provided downward in the middle of the top end of the convex column 122. The heavy object block 11 is made of an iron block to provide weight. The rubber sleeve support block 12 is preferably made of an iron block or a wooden block. The rubber sleeve is placed into the accommodation groove 121, and the rubber sleeve is sleeved on the convex column 122 through the inner hole, so as to realize the support and positioning of the rubber sleeve.
[0016] Two cylindrical platforms 21 are formed in the middle of the assembly rod 2. The two cylindrical platforms 21 are arranged at intervals along the length direction of the assembly rod 2, and the interval is set to match the length of the heat shrinkable tube. Annular grooves 211 are concavely provided on the outer walls of the two cylindrical platforms 21. Rubber rings 22 are installed in the annular grooves 211 in a limited manner. The rubber rings 22 protrude from the annular grooves 211. The cylindrical metal tubes are sleeved onto the assembly rod 2 from both ends of the assembly rod 2. The two cylindrical metal tubes are respectively located at the positions of the cylindrical platforms 21 to be tension-fixed by the rubber rings 22, and the distance between the two cylindrical metal tubes is positioned to match the length of the heat shrinkable tube. The length of the cylindrical metal tube is greater than the length of the cylindrical platform 21.
[0017] When the assembly rod 2 is inserted into the limit groove 123, a cylindrical platform 21 penetrates into the inner hole of the rubber sleeve, so that a cylindrical metal tube penetrates into the inner hole of the rubber sleeve and abuts against the abutting block in the inner hole. The joint tube is sleeved into the assembly rod 2 through the inner hole, and the cylindrical metal tube fixed by the cylindrical platform 21 above abuts against the abutting block in the inner hole of the joint tube to support the joint tube.
[0018] Furthermore, the number of the annular grooves 211 recessed in the two cylindrical platforms 21 is two, and the number of the rubber rings 22 matches the number of the annular grooves 211. Each cylindrical metal tube has two rubber rings 22 for tensioning and fixing, and the fixing effect is good, so that the cylindrical metal tube is not likely to fall off autonomously during assembly.
[0019] The implementation principle of an assembly jig for a catheter structure in this application is as follows: The two cylindrical metal tubes are respectively sleeved into the assembly rod 2 from both ends of the assembly rod 2. When the cylindrical metal tubes move to the position of the cylindrical platform 21, they are tensioned and fixed by the rubber rings 22. The two cylindrical metal tubes are respectively fixed on the two cylindrical platforms 21, and the distance between them is positioned and matched with the distance of the heat shrinkable tube. By threading the heat shrinkable tube into the assembly rod 2, the two ends of the heat shrinkable tube are respectively sleeved onto the two cylindrical metal tubes. Squeezing the heat shrinkable tube realizes fixing the heat shrinkable tube at the position of the aligned cylindrical metal tube. When heating the end of the heat shrinkable tube with a heat gun to make it shrink and fit onto the outer wall of the cylindrical metal tube, it is relatively easy and convenient. After the heat shrinkable tube is shrunk and fixed on the outer wall of the cylindrical metal tube, the rubber sleeve is placed into the accommodating groove 121 of the rubber sleeve support block 12, and the rubber sleeve is sleeved into the convex column 122 through the inner hole. The rubber sleeve is supported. By inserting the assembly rod 2 into the limit groove 123, the assembly rod 2 is fixed, and a cylindrical metal tube penetrates into the inner hole of the rubber sleeve and abuts against the abutting block in the inner hole, realizing the preliminary assembly of the cylindrical metal tube and the rubber sleeve. The joint tube is sleeved into the assembly rod 2 through the inner hole at the top of the assembly rod 2 on it, and the joint tube is supported by abutting a cylindrical metal tube above against the bottom contact block in the inner hole of the joint tube. By applying UV curing glue between the inner hole wall of the rubber sleeve and the inner hole wall of the joint tube and the corresponding cylindrical metal tube, and then irradiating the glue application part with a UV lamp to realize the rapid curing of the UV curing glue, the assembly of the catheter structure is completed. By using the assembly jig in this application to assist in positioning and supporting each component, the assembly efficiency of the catheter structure is higher.
[0020] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
