Description

Technical Field

[0001] This utility model relates to the field of catheter connection technology, specifically a catheter connector. Background Technology

[0002] A catheter is a tubular instrument used in medical procedures. It is mainly used to deliver fluids such as drugs, nutrients, and blood inside the human body or in contact with human tissues, or to drain fluids and gases from the body. It can also serve as a channel for examination or treatment. Its purpose is to assist medical procedures, help diagnose diseases, treat patients, or maintain the body's normal physiological functions.

[0003] When using catheters, it is inevitable that there will be situations where the catheter length is insufficient and an additional catheter needs to be added. The existing method is to connect the two catheters with a connector. However, after the connection is made, the catheters need to be reinforced by binding. This is not only very troublesome, but also prone to problems such as improper binding, which can lead to catheter detachment and leakage. The fixation effect is not ideal. Utility Model Content

[0004] The purpose of this invention is to provide a catheter connector to solve the problems of unsatisfactory fixation effect during catheter connection in the prior art, which easily leads to catheter detachment and leakage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conduit connector, comprising a hollow connecting cylinder, wherein the left and right side walls of the hollow connecting cylinder are provided with slots, a connecting pipe is fixedly connected to the middle of the inner cavity wall of the slot, a reinforcing block is provided in the inner cavity of the slot, a T-shaped groove is provided in the middle of the top of the hollow connecting cylinder, and a limiting component is provided in the inner cavity of the T-shaped groove.

[0006] Two reinforcing blocks are symmetrically arranged above and below the connecting pipe. A reinforcing rod is fixedly connected to the top of the upper reinforcing block and the bottom of the lower reinforcing block. The end of the reinforcing rod extends to the outside of the hollow connecting cylinder, and the outer wall of the reinforcing rod is slidably connected to the inside of the hollow connecting cylinder. Rings are screwed to the left and right sides of the outer wall of the hollow connecting cylinder. The two rings are located on the left and right sides of the T-slot, respectively. A conical limiting cover is fixedly connected to the outer wall of the two rings. The inner wall of the conical limiting cover contacts the end of the two reinforcing rods.

[0007] It can reinforce the connection after the catheter is connected, thereby preventing leakage and detachment during use.

[0008] Preferably, the end of the reinforcing rod is sloped.

[0009] The slope is designed to ensure a better fit between the reinforcing rod and the inner wall of the conical limiting cover.

[0010] Preferably, anti-slip pads are provided at the bottom of the upper reinforcing block and at the top of the lower reinforcing block.

[0011] Anti-slip pads enhance the fixation effect while preventing damage to the catheter from hard contact.

[0012] Preferably, the two connecting pipes are connected to the inner cavity of the hollow connecting cylinder, and one end of the connecting pipe is tapered, with the tapered end located in the inner cavity of the slot.

[0013] By making the connecting end of the connecting pipe tapered, it is easier to install conduits of different sizes.

[0014] Preferably, the limiting component includes a T-shaped block, which is slidably connected to the inner cavity of the T-shaped groove. There are two T-shaped blocks, which are symmetrically arranged on the left and right sides of the inner cavity of the T-shaped groove. The top of the T-shaped block extends to the outer side of the T-shaped groove. Springs are fixedly connected to the left and right sides of the inner cavity wall of the T-shaped groove. The ends of the springs are fixedly connected to the outer side walls of the T-shaped blocks on the left and right sides. Limiting blocks are fixedly connected to the outer side walls of the T-shaped blocks on the left and right sides, and the limiting blocks are located on the outer side of the T-shaped groove.

[0015] The ring is positioned by a limiting component, thereby improving the fixing effect.

[0016] Preferably, the inner sidewalls of the left and right rings are provided with limiting grooves, and the limiting grooves are evenly distributed in a ring shape, with the outer sidewall of the limiting block engaging with the inner wall of the limiting groove.

[0017] The ring is positioned by using a slot and a limiting block to limit its movement, resulting in greater stability. The slot also helps to prevent slippage when the ring is rotated.

[0018] Preferably, the outer walls of the T-shaped blocks on the left and right sides are provided with screw holes, and the screw holes are located above the limiting block. A fixing screw is screwed into the inner wall of the screw hole on the right side.

[0019] The T-block is secured by screws through screw holes during the installation and removal of the conduit, thus facilitating subsequent operations.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This application allows for convenient and quick installation of the conduit via a connecting tube. After installation, the connection point of the conduit is reinforced by a reinforcing block in conjunction with the connecting tube, thereby improving the stability of the conduit connection and preventing the conduit from falling off or leaking during use.

[0022] 2. This application uses a limiting component in conjunction with a limiting slot to limit the ring body, preventing the ring body from becoming loose due to its own or external factors during use, thereby improving the overall fixing effect and making it more stable.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figures 1-4 As shown, this utility model provides a technical solution for a conduit connector, including a hollow connecting cylinder 100. The left and right side walls of the hollow connecting cylinder 100 have slots 110. A connecting pipe 111 is fixedly connected to the middle of the inner wall of the slot 110. A reinforcing block 200 is provided in the inner cavity of the slot 110. A T-shaped groove 112 is opened in the middle of the top of the hollow connecting cylinder 100. A limiting component 300 is provided in the inner cavity of the T-shaped groove 112.

[0030] Please refer to this carefully. Figures 1-4There are two reinforcing blocks 200, symmetrically arranged above and below the connecting pipe 111. A reinforcing rod 210 is fixedly connected to the top of the upper reinforcing block 200 and the bottom of the lower reinforcing block 200. The end of the reinforcing rod 210 extends to the outside of the hollow connecting cylinder 100, and the outer wall of the reinforcing rod 210 is slidably connected to the inside of the hollow connecting cylinder 100. Rings 211 are screwed to the left and right sides of the outer wall of the hollow connecting cylinder 100. The two rings 211 are located on the left and right sides of the T-slot 112, respectively. A conical limiting cover 212 is fixedly connected to the outer wall of the two rings 211. The inner side of the conical limiting cover 212... The wall contacts the ends of the two reinforcing rods 210. The ends of the reinforcing rods 210 are sloped. The bottom of the upper reinforcing block 200 and the top of the lower reinforcing block 200 are provided with anti-slip pads. The two connecting pipes 111 are connected to the inner cavity of the hollow connecting cylinder 100. The end of the connecting pipe 111 located in the inner cavity of the slot 110 is tapered. The conduit connector facilitates and quickly installs the conduit through the connecting pipe 111. After installation, the reinforcing block 200 cooperates with the connecting pipe 111 to reinforce the connection of the conduit, thereby improving the stability of the conduit connection and preventing the conduit from falling off and leaking during use.

[0031] Please refer to this carefully. Figures 1-4 The limiting component 300 includes two T-shaped blocks 310, which are slidably connected to the inner cavity of the T-shaped groove 112. The T-shaped blocks 310 are symmetrically arranged on the left and right sides of the inner cavity of the T-shaped groove 112. The tops of the T-shaped blocks 310 extend to the outer side of the T-shaped groove 112. Springs 311 are fixedly connected to the left and right sides of the inner cavity wall of the T-shaped groove 112, and the ends of the springs 311 are fixedly connected to the outer walls of the T-shaped blocks 310. Limiting blocks 312 are fixedly connected to the outer walls of the left and right sides of the T-shaped blocks 310, and the limiting blocks 312 are located on the outer side of the T-shaped groove 112. The inner walls of the left and right annular bodies 211... The side wall has a limiting groove 220, which is evenly distributed in a ring. The outer side wall of the limiting block 312 engages with the inner wall of the limiting groove 220. The outer side wall of the T-shaped blocks 310 on both sides has a screw hole 320, which is located above the limiting block 312. A fixing screw is screwed into the inner wall of the right screw hole 320. The conduit connector uses the limiting component 300 to limit the ring 211 in conjunction with the limiting groove 220, so as to avoid the ring 211 from loosening due to its own or external factors during use, thereby improving the overall fixing effect and stability.

[0032] In use, the two conduits are respectively fitted onto the connecting pipes 111 located in the slots 110 on both sides, so that the two conduits are connected with the hollow connecting cylinder 100. The rings 211 on both sides are rotated and moved outward on the hollow connecting cylinder 100. The rings 211 drive the conical limiting cover 212 to move and contact the slope of the top of the reinforcing rod 210. As the rings 211 move, the conical limiting cover 212 squeezes the two reinforcing rods 210 and drives the reinforcing blocks 200 to move in opposite directions and contact the conduits. The two reinforcing blocks 200, together with the connecting pipes 111, squeeze and fix the conduits, thereby reinforcing the connection.

[0033] During installation, the two T-blocks 310 are simultaneously pulled inward and slid in the T-slots 112. As the T-blocks 310 move, they stretch the spring 311, causing the two T-blocks 310 to come into contact. The two T-blocks 310 are then fixed together by the fixing screws and screw holes 320, which facilitates the subsequent installation of the conduit. After the conduit is installed, the fixing spring 311 is released and springs back, causing the T-blocks 310 to reset. The T-blocks 310 then cause the limiting block 312 to engage with the corresponding limiting slot 220, thereby limiting the ring 211.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
