Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pleural effusion drainage device. Background Art

[0002] Closed chest drainage is to place one end of the drainage tube into the chest cavity, and connect the other end to a water-sealed bottle at a lower position, so as to discharge gas or collect fluid in the chest cavity, so that the lung tissue can reopen and restore function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases.

[0003] In the prior art, after the drainage tube is inserted into the chest cavity, the doctor needs to sew and fix the drainage tube to the patient's skin with needle and thread, and then stick adhesive tape on it. This is not only time-consuming and labor-intensive, but also has poor stability. The drainage tube is prone to tilt or even fall off when subjected to a large external force. Therefore, we have launched a pleural effusion drainage device. Utility Model Content

[0004] The purpose of the utility model is to provide a pleural effusion drainage device, which can facilitate the rapid positioning of the drainage tube, save time and effort and has high efficiency, and can also effectively prevent the drainage tube from tilting and falling off from the patient's chest cavity due to external force, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pleural effusion drainage device comprises a drainage tube and a positioning plate, wherein the lower end of the drainage tube is sealed, a plurality of drainage holes are evenly provided on the lower tube wall of the drainage tube, a circular hole is provided in the middle of the upper end of the positioning plate, the outer tube wall of the drainage tube is slidably connected to the hole wall of the circular hole, a positioning tube is fixedly provided at the upper end of the positioning plate located outside the drainage tube, a mounting plate is fixedly provided at the outer tube wall of the drainage tube located on the lower side of the positioning plate, strip holes are provided at the bottom of the positioning plate located on both sides of the mounting plate, a clamping mechanism is provided between the strip holes and the mounting plate, an adhesive cloth is fixedly provided at the bottom of the positioning plate, a through hole is provided in the middle of the adhesive cloth, and the mounting plate is arranged inside the through hole.

[0007] Preferably, the clamping mechanism includes an elastic rod, which is vertically slidably arranged in the strip hole at a side away from the drainage tube, the lower end of the elastic rod is fixedly connected to the upper end of the mounting plate, and the upper end of the elastic rod extends outside the strip hole away from the drainage tube and is fixedly connected to a clamping block.

[0008] Preferably, an inclined surface is provided on the upper end of the clamping block.

[0009] Preferably, the angle of the inclined surface is set to 45°.

[0010] Preferably, an elastic band is fixedly provided on the upper end of the mounting plate, a placement hole is opened in the middle of the elastic band, the positioning tube is located inside the placement groove, and the two ends of the elastic band are fixedly connected by Velcro.

[0011] Preferably, the lower end of the drainage tube is configured as a round head.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The pleural effusion drainage device is provided with Velcro, elastic band, drainage tube, positioning tube, adhesive cloth, positioning plate, clamping block, elastic rod, mounting plate and drainage hole. First, the round head of the drainage tube is inserted into the chest cavity through the chest wound, and then the round hole of the positioning plate is sleeved on the tube wall of the drainage tube. The inclined surface of the clamping block allows the elastic rod to be bent and enter the strip hole. When the clamping block is located on the upper side of the positioning plate, the lower end of the clamping block abuts against the upper end of the positioning plate. At this time, the protective film on the bottom of the adhesive cloth is torn off, and the adhesive on the bottom of the adhesive cloth is pressed to fit the patient's skin. Finally, the two ends of the elastic band are wrapped around the patient's body and fixedly connected by Velcro, which can facilitate the rapid positioning of the drainage tube, save time and effort, and has high efficiency. It can also effectively prevent the drainage tube from tilting and falling off from the patient's chest cavity due to external force, and has high stability. BRIEF DESCRIPTION OF THE DRAWINGS
