Description

Technical Field

[0001] This utility model relates to the field of medical plastic connectors, and in particular to a high-sealing medical plastic connector. Background Technology

[0002] Currently, medical plastic connectors are widely used in the medical field and are an indispensable component of medical devices. They are typically used to connect pharmaceutical packaging, disposable medical devices (such as infusion bottles, syringes, catheters, etc.) and non-disposable medical devices (such as measuring instruments, surgical instruments, etc.).

[0003] However, when using plastic connectors to connect infusion tubing, these connectors, with their relatively simple structure and function, often lack adjustable connection lengths. This results in the connector end not fully connecting and closing with the end of the tubing to be connected, leaving gaps and affecting the sealing of the tubing connection. Therefore, we propose a high-sealing medical plastic connector. Utility Model Content

[0004] The main objective of this invention is to provide a high-sealing medical plastic connector that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-sealing medical plastic connector includes two sets of connecting tubes, with a corrugated connecting tube fixedly connected between the sides of the two sets of connecting tubes, and a connecting threaded tube screwed onto the outer surface of each connecting tube.

[0007] A limiting mechanism is provided laterally between the two outer ends of each pair of connecting threaded pipes, and the limiting mechanism is located on the outside of the corrugated connecting pipe. A sealing gasket is fixedly connected to the outer end of each connecting threaded pipe away from the connecting pipe.

[0008] By adopting the above technical solution, the corrugated connecting pipe and the threaded connecting pipe can be used to adjust the horizontal position of the connecting thread on the outside of the connecting pipe after the thread is tightened. This allows the threaded connecting pipe to be screwed onto the outside of the pipe to be connected, further increasing the overall connection length of the connector and ensuring that the threaded connecting pipe can be fully screwed onto the outside of the pipe, thereby improving the sealing performance between the pipes.

[0009] As an optional solution to the technical solution of this application, the limiting mechanism includes a guide frame and a connecting plate. Each of the connecting threaded pipes has a connecting plate slidably installed at both ends on the side near the corrugated connecting pipe. A guide frame is slidably sleeved between the outer sides of the two sets of connecting plates. Both the guide frame and the connecting plate are located on the outer side of the corrugated connecting pipe. Each guide frame has a storage groove inside, and the connecting plate is slidably inserted into the storage groove.

[0010] By adopting the above technical solution, the guide frame guides the connecting plate to slide and bend, preventing the threaded pipe and corrugated connecting pipe from bending arbitrarily and affecting the connectivity.

[0011] As an optional solution to the technical solution of this application, each of the guide frames has a guide groove at the middle of both ends of its inner side, and each of the connecting plates has a guide slider fixedly installed on both outer sides, and the guide slider is slidably inserted into the guide groove.

[0012] By adopting the above technical solution, the guide slide groove can guide the guide slider, ensuring that the connecting plate can only move horizontally inside the guide frame.

[0013] As an optional solution to the technical solution of this application, a limiting slider is fixedly installed at one end of each connecting plate near the connecting threaded tube, and a limiting groove is opened on the side of each connecting threaded tube, and the limiting slider is slidably inserted into the limiting groove.

[0014] By adopting the above technical solution, under the limiting sliding action of the limiting slide groove on the limiting slider, it can be ensured that when the connecting threaded pipe is screwed, the connecting plate can only slide on its side and will not detach from its surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present application provides a high-sealing medical plastic connector that connects two sets of connecting pipes via a corrugated connecting pipe. Due to the inherent extension and connectivity of the corrugated connecting pipe, when it is necessary to connect the pipes at both ends of the connecting pipe, the length of the connection position can be adjusted by pulling the two sets of connecting pipes. Furthermore, combined with the threaded connecting pipe screwed onto the outside of the connecting pipe, the horizontal position of the threaded connecting pipe on the outside of the connecting pipe can be adjusted by screwing the threaded connecting pipe onto the outside of the pipe to be connected. This further increases the overall connection length of the connector, ensuring that the threaded connecting pipe can be fully screwed onto the outside of the pipe, thereby improving the sealing performance between the pipes.

[0017] 2. A high-sealing medical plastic connector according to the technical solution of this application, by setting a guide frame and a connecting plate between the sides of two sets of connecting threaded pipes, and combined with the guiding sliding action of the guide slide groove on the guide slider, the connecting plate can only move horizontally inside the guide frame and will not bend laterally. Thus, the corrugated connecting pipe can only move horizontally when moving and will not bend excessively, affecting the subsequent delivery efficiency of the drug solution.

[0022] like Figure 1-3 As shown, this utility model provides a technical solution: a high-sealing medical plastic connector, in which a corrugated connecting pipe 2 is fixedly connected between the sides of two sets of connecting pipes 1, and a connecting threaded pipe 21 is screwed onto the outer surface of each connecting pipe 1, and a limiting mechanism is laterally provided between the two outer ends of each pair of connecting threaded pipes 21, and the limiting mechanism is located outside the corrugated connecting pipe 2, and a sealing gasket 22 is fixedly connected to the outer end of each connecting threaded pipe 21 away from the connecting pipe 1.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the limiting mechanism includes a guide frame 3 and a connecting plate 31. Each of the connecting threaded pipes 21 has a connecting plate 31 slidably installed at both ends on the side near the corrugated connecting pipe 2. A guide frame 3 is slidably sleeved between the outer sides of the two sets of connecting plates 31, and both the guide frame 3 and the connecting plate 31 are located on the outer side of the corrugated connecting pipe 2.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown in the figure, each of the guide frames 3 has a storage slot 32 inside, and the connecting plate 31 is slidably inserted into the storage slot 32.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, each of the guide frames 3 has a guide groove 4 at the middle of both ends of its inner side, and each of the connecting plates 31 has a guide slider 41 fixedly installed on both outer sides, and the guide slider 41 is slidably inserted into the guide groove 4.

[0026] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown, each of the connecting plates 31 is fixedly installed with a limiting slider 42 at one end near the connecting threaded tube 21. Each of the connecting threaded tubes 21 has a limiting groove 43 on its side, and the limiting slider 42 is slidably inserted into the limiting groove 43. The cross-sections of the limiting groove 43 and the limiting slider 42 are both T-shaped, so that the limiting slider 42 will not arbitrarily detach from the side of the connecting threaded tube 21.

[0027] During operation, when connecting two sets of pipes, the threaded connecting pipe 21 on one side is screwed sequentially. Combined with the guiding sliding action of the limiting slide groove 43 on the limiting slider 42, the contact position of the connecting plate 31 and the threaded connecting pipe 21 can rotate relative to each other. As the connecting pipe 1 moves horizontally outward, the threaded connecting pipe 21 is simultaneously screwed onto the outside of the pipe to be connected. Under the connecting action of the threaded connecting pipe 21, the connecting pipe 1 and the external pipe can be connected. Then, the threaded connecting pipe 21 on the other side is repeatedly screwed on. Connected to the outside of the external pipeline, the two sets of required pipelines are connected by the connecting pipe 1, the corrugated connecting pipe 2, and the connecting threaded pipe 21. If the distance between the two sets of required pipelines is too large, the connecting threaded pipe 21 on one side is pulled. Simultaneously, under the guiding sliding action of the guide slide groove 4 on the guide slider 41, the two sets of connecting plates 31 can move horizontally synchronously under the guiding sliding action of the guide frame 3 to adjust the distance. After repeating the above operation steps, the two sets of pipelines to be connected are connected for use.
