Drainage catheter for thoracocentesis

Abstract

The invention discloses a drainage catheter for thoracocentesis. The drainage catheter comprises a drainage tube, an arc-shaped tube is arranged at one end of the drainage tube, drainage side holes are uniformly formed in the lower surface of the arc-shaped tube, a fixing ring sleeves the outer surface of one end of the drainage tube, an adhering material is fixedly arranged on the surface of oneside of the fixing ring, and a first drainage tube is arranged at the other end of the drainage tube. The drainage catheter is reasonable in structural design and easy and convenient to operate; in order to overcome the defects of an existing drainage tube, on the basis of basic drainage puncturing, puncturing components are integrated, improved and optimized, the auxiliary fixing device is additionally installed to fix the puncturing drainage device, the smoothness of puncturing drainage is stabilized, safety is improved, integration of the drainage device is realized, operation processes aresimplified, the learning and operating difficulty of non-professionals is lowered, the success rate of wounded thoracic cavity first aid is increased, the time for wounded thoracic cavity first aid is shortened, and large-scale application and popularization are convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thoracentesis drainage catheter. Background technique [0002] The thoracentesis drainage catheter is a medical device that is used clinically for hemothorax, pneumothorax and other emergency thoracentesis. It can solve the patient's hypoxic situation, thereby improving the patient's dyspnea problem. [0003] However, the components of the traditional drainage tube are complex and diverse, the puncture process is cumbersome, time-consuming, and cannot be fixed. It needs long-term support from the staff. Time, it is very difficult for non-professionals to operate emergency, the puncture process takes a long time, delays the best first aid time, and the puncture effect is not ideal. [0004] A Chinese patent discloses a drainage tube (authorized notification number CN106492325U). This patented technology can improve the supporting effect and reduce drainage through the a...

[0003] However, the components of the traditional drainage tube are complex and diverse, the puncture process is cumbersome, time-consuming, and cannot be fixed. It needs long-term support from the staff. time, it is very difficult for non-professionals to operate emergency, the puncture process takes a long time, delays the best first aid time, and the puncture effect is not ideal

[0004] A Chinese patent discloses a drainage tube (authorized notification number CN106492325U). This patented technology can improve the supporting effect and reduce drainage through the angle between two adjacent support bars is 120 degrees, and the three support bars are arranged symmetrically. The tubes are blocked and communicate with each other through the holes on the wall of the support bar. Once one cavity is blocked, the drainage fluid will enter the other channel through the holes on the wall to reduce the rate of blockage. The function of the air bag is to prevent the drainage tube from slipping out of the cavity. Cooperate with the lock to prevent leakage and the outer end of the lumen to slide in and pollute the drainage cavity, but the device is not equipped with a fixing device for the drainage tube, but when the patient needs to be punctured and drained, the lack of a fixing device may cause drainage The tube is bent, which makes the drainage unsmooth and affects the patient's condition

[0005] A Chinese patent discloses a three-way drainage tube (authorized announcement number CN102371007U). This device is simple in structure and easy to use. It can completely drain the patient and reduce the work difficulty of the medical staff. However, the device is prone to If there is a blockage, the patient's chest cavity cannot be drained smoothly, which will have a certain impact on the patient's condition
