[0023] To make the purpose, technical scheme and advantages of the utility model more clear, the following will combine the utility model specific embodiment and corresponding drawing to clearly, completely describe the utility model technical scheme. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor, belong to the scope of the utility model protection.
[0024] The following will combine the drawing, and specifically describe the technical scheme provided by each embodiment of the utility model.
[0025] The utility model embodiment provides a kind of thoracic drainage tube anti-disengagement connector, as shown in figure Figure 1 As shown in figure, it is the prior art structure schematic view provided by the utility model, by syringe barrel 6 and two section drainage tube are connected, after the connecting place of both ends is bound by adhesive tape etc., prevent the purpose of disengagement, and when disassembling, adhesive tape needs to be pulled down, it is more troublesome, therefore the utility model makes the following improvement:
[0026] As shown in figure Figures 2-6As shown, the traditional syringe barrel 6 is improved into a connection pipe body 1 with open ends, which are used for the insertion of drainage tubes, such as one end connected with the drainage tube in the patient's chest cavity, and the other end connected with a collecting container such as a water seal bottle, a drainage bottle, etc. A bunching unit 2 is further arranged at both ends of the connection pipe body 1. The bunching unit 2 includes a plurality of bunching portions 21 arranged at a circumferential equidistance of the central axis of the connection pipe body 1 and having flexibility. The bunching unit 2 is in a radial expansion shape and can be inwardly contracted under the axial force and restored after the force disappears. Threads are arranged on the outer walls of the connection pipe body 1 and the bunching unit 2. A fastener 3 is threadedly connected to the connection pipe body 1. When the fastener 3 is threadedly connected to the outer side of the bunching unit 2, the bunching unit 2 is forced to be inwardly contracted. The bunching portion 21 can be made of a material such as plastic with thin thickness and can be inwardly moved under pressure to realize the wrapping state of the drainage tube inserted into the inside of the connection pipe body 1, thereby reducing the possibility of the drainage tube falling off. In order to reduce the liquid leakage phenomenon after the drainage tube is inserted into the connection pipe body 1, a mounting ring 4 is further arranged on the inner wall of the connection pipe body 1. A sealing ring 41 is arranged on the inner wall of the mounting ring 4 to realize the sealing by abutting against the outer wall of the drainage tube. After the drainage tube is inserted into the inside of the connection pipe body 1, the sealing between the drainage tube and the inner wall of the connection pipe body 1 is realized by the close abutment of the sealing ring 41 and the outer wall of the drainage tube, thereby avoiding the leakage of the drainage liquid from the gap between the drainage tube and the connection pipe body 1.
[0027] In order to make the wrapping stability of the bunching unit 2 to the connection pipe body 1 better, a protruding portion 22 is arranged on the inner wall of the bunching portion 21. A friction pad 23 is arranged on the protruding portion 22. When the fastener 3 is threadedly connected to the bunching unit 2, the plurality of bunching portions 21 are in the state of being parallel to the axial direction of the connection pipe body 1. At this time, the protruding portion 22 drives the friction pad 23 to be located inside the orthographic projection plane of the connection pipe body 1 to press the inserted drainage tube. Even if the diameter of the drainage tube is small, the friction pad 23 can be driven by the protruding portion 22 to abut against the outer wall of the drainage tube and increase the abutment with the drainage tube through the friction pad 23, thereby improving the fixing effect of the drainage tube. The friction pad 23 can be made of rubber or medical silica gel.
[0028] Preferably, the inner diameter of the mounting ring 4 gradually decreases from the end of the connection pipe body 1 to the middle part of the connection pipe body 1, which can be suitable for the installation of drainage tubes with different diameters and has a wider application range.
[0029] Preferably, the fastener 3 is provided with an abutting ring 31 near one end of the bundle port unit 2, and the diameter of the abutting ring 31 gradually decreases in the direction close to the bundle port unit 2, and the minimum inner diameter of the abutting ring 31 is equal to the outer diameter of the connecting pipe body 1, when the fastener 3 is moved in the direction of the bundle port unit 2, the radial bundle port unit 2 will first be inwards contracted to a certain extent through the abutting ring 31, that is, contracted to the state that the length extension direction of the bundle port 21 is parallel to the axial direction of the connecting pipe body 1, facilitating the threaded rotation of the fastener 3 to the bundle port unit 2.
[0030] Preferably, the flexible limiting rope 5 is connected between the adjacent two bundle ports 21, so that the radial bundle port unit 2 maintains a certain form, and it is not easy for a single bundle port 21 to appear an outward protruding phenomenon, and the integrity of the bundle port unit 2 is maintained.
[0031] Preferably, the connecting pipe body 1 includes a bendable flexible part 11 in the middle and fixed connecting parts 12 connected to both ends of the bendable flexible part 11, the fixed connecting parts 12 can be made of plastic or some other materials with a certain hardness, which will not easily deform, and the mounting ring 4 is located in the fixed connecting part 12, facilitating the installation of the drainage tube, and the bendable flexible part 11 can be made of a metal shaped hose, and ordinary hard pipes are easy to twist during patient movement, resulting in poor drainage, and the bendable flexible part 11 has the characteristics of being bendable, and can be bent and restored to a certain extent, effectively buffering external force generated by patient movement, reducing the risk of twisting of the drainage tube. For example, when the patient turns over, the metal shaped hose can bend to adapt to the body rotation, keep the inside of the drainage tube unobstructed, ensure that the pleural effusion or gas can be smoothly drawn out through the drainage tube, and can be bent according to actual needs, change the connection direction, so that medical staff can more conveniently connect the drainage tube with other equipment, and facilitate connection operation.
[0032] The above only describes the embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
