Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-blocking chest drainage suction head. Background Art

[0002] A pleural effusion drainage tube is a medical device that is inserted into the pleural cavity to treat pleural effusion and discharge the fluid or gas accumulated in the pleural cavity from the body. It is mainly composed of a tube head, a tube body and a drainage bottle. The tube head, also known as the suction tip, refers to the front end of the drainage tube used to contact the effusion and suck the effusion into the inside of the drainage tube.

[0003] However, the existing chest drainage suction tips still have certain defects when in use. For example, when in use, most of the existing chest drainage suction tips simply fix the drainage tube to the patient's skin with medical sterile breathable adhesive tape or fix it by skin suture. Among them, when the patient frequently moves, turns over or coughs up phlegm, the adhesive tape may lose its viscosity due to sweat, causing the drainage tube to shift or fall off, affecting the drainage effect and increasing the risk of infection. The fixation method of skin suture will cause more pain and discomfort to the patient. At the same time, the sutured wound also increases the possibility of bacterial infection. In addition, the existing chest drainage suction tips are easily blocked by tissue protein when in use, causing blockage of the drainage tube, affecting the continuity and effectiveness of the drainage of the effusion, thereby delaying the patient's recovery.

The anti-blocking chest drainage tip is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0026] See also Figure 1-6 In the present embodiment, a blockage-proof chest drainage tip is provided, comprising: a drainage tube tip 1, a liquid inlet cavity 5 is provided inside the drainage tube tip 1, a drainage tube body 2 is provided inside the liquid inlet cavity 5, and two filter screens 102 are provided on the outside of the drainage tube tip 1; an anti-blockage component provided between the drainage tube tip 1 and the drainage tube body 2, for cleaning the lumps on the filter screen 102; and a fixing component provided at one end of the drainage tube tip 1, for enhancing the stability of the drainage tube tip 1.

[0027] Among them, by setting the anti-blocking component, the possibility of blood clots and fibrin clots accumulating in the drainage tube body 2 can be reduced, ensuring that the effusion can be continuously and effectively discharged from the body, thereby improving the drainage efficiency of the pleural effusion;

[0028] Secondly, by setting up the fixing component, the stability of the drainage tube tip 1 in the patient's body can be enhanced, and the displacement or falling off of the drainage tube tip 1 caused by the patient's activities, turning over, etc. can be avoided. Example 2

[0029] On the basis of Example 1, the anti-blocking component includes: an annular stopper 101 arranged on the outside of the drainage tube suction head 1, an annular scraper 103 is arranged between the annular stopper 101 and the drainage tube suction head 1, two limit columns 108 are arranged at one end of the outer side of the drainage tube suction head 1, and the two limit columns 108 are symmetrically arranged about the drainage tube body 2; a fixing rod 104 is arranged at one end of the drainage tube body 2, a through hole 106 is opened on one side of the drainage tube suction head 1, and the fixing rod 104 passes through the through hole 1 06, and is fixedly connected with a U-shaped connecting rod 105; the outer side of the annular scraper 103 is fixedly connected to the annular block 101, and one end of the U-shaped connecting rod 105 is fixedly connected to one side of the annular scraper 103; a sealing ring 501 is provided between the drainage tube body 2 and the drainage tube suction head 1, and the outer side of the sealing ring 501 is fixedly connected to the inner wall of the liquid inlet cavity 5; a plurality of liquid inlet holes 201 are opened at one end of the drainage tube body 2 located at the liquid inlet cavity 5, and the plurality of liquid inlet holes 201 are evenly distributed in a circular array.

[0030] During use, medical staff can connect one end of the drainage tube body 2 to the drainage device or drainage bottle, and then insert the drainage tube tip 1 into the patient's chest cavity until the two limit columns 108 at one end of the drainage tube tip 1 are in contact with the patient's skin, and then fix it with the elastic band a3, the hook-surface Velcro 301, the elastic band b4 and the velvet Velcro 401 to drain the effusion. During the drainage process, the effusion located inside the chest cavity is filtered through the filter net 102 on the outside of the drainage tube tip 1 and enters the liquid inlet cavity 5. Then, it enters the interior of the drainage tube body 2 from the multiple liquid inlet holes 201 on the drainage tube body 2 and flows out of the chest cavity along the drainage tube body 2, thereby draining the effusion out of the patient's chest cavity.

[0031] When the two filter screens 102 outside the drainage tube suction head 1 are clogged with blood clots and fibrin clots, the medical staff can gently press the two limit columns 108, and then pull the drainage tube body 2 along the inner wall of the liquid inlet chamber 5, so that the drainage tube body 2 drives the fixing rod 104, the U-shaped connecting rod 105, the annular scraper 103 and the annular stopper 101 to move back and forth along the outside of the drainage tube suction head 1. During this process, the annular scraper 103 will scrape off the blood clots and fibrin clots adhered to the two filter screens 102, and the annular stopper 101 will cooperate with the annular scraper 103 to concentrate the blood clots and fibrin clots between the drainage tube suction head 1 and the annular stopper 101, and push them away from the drainage tube suction head 1, so as to reduce the blood clots and fibrin clots that are pushed away and then re-adhered to the filter screens 102 due to the effusion. Example 3

[0032] On the basis of Example 1, the fixing component includes: two notches 107 opened at one end of the outer side of the drainage tube suction head 1, and connecting ropes 303 are passed through the inside of the two notches 107; an elastic band a3 is arranged at one end of the drainage tube suction head 1, and one end of the elastic band a3 is fixedly connected with a hook-surface Velcro 301, and one end of the drainage tube suction head 1 is provided with an elastic band b4, and one side of the elastic band b4 is provided with a suede Velcro 401; the suede Velcro 401 and one end of the elastic band a3 are fixedly connected with a connecting belt 302, and the two ends of the two connecting ropes 303 are respectively fixedly connected to the two connecting belts 302.

[0033] During use, medical staff can insert the drainage tube tip 1 into the patient's chest cavity until the two limiting columns 108 at one end of the drainage tube tip 1 contact the patient's skin, and adjust the connecting belt 302 and the connecting rope 303 to a suitable position so that the elastic belt a3 and the elastic belt b4 are parallel to the chest, and then wrap the elastic belt a3 and the elastic belt b4 around the patient's back, and make the hook surface Velcro 301 adhere to the velvet Velcro 401 to complete the fixation of the drainage tube tip 1.
