Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thoracentesis and drainage, in particular to a thoracentesis and drainage tube. Background Art
[0002] Thoracentesis, abbreviated as thoracentesis, refers to a technique of extracting fluid or gas through thoracentesis for the purpose of diagnosis and treatment of diseases in patients with pleural effusion.
[0003] The existing chest drainage tube often causes pain and discomfort at the tube placement site due to suture fixation, and often causes tube blockage and poor drainage, which brings pain to the patient and affects the treatment effect.
[0004] In view of this, Chinese patent CN218474785U discloses an internally fixed suture-free chest drainage catheter. By setting the airbag and the buckle to be mushroom-shaped and opposite in shape, when the drainage tube body is inserted into the human body, the airbag is inflated to make it cooperate with the buckle, and the drainage tube body is fixed at the chest incision, so that no suture fixation is required, the patient's pain is alleviated, and complications such as subcutaneous emphysema, bleeding and exudation are reduced. By embedding and installing an inflation tube on the inner side of the airbag and communicating with the inflation one-way valve, it is convenient for the user to inflate and deflate the airbag through the inflation tube. By installing an adapter and installing a three-way tube, the three-way tube can be connected to a water seal bottle, a drainage bag or a negative pressure suction device. By installing a reinforcing tube, the drainage tube body is prevented from being squeezed by the patient's incision after the tube is placed, resulting in deformation of the drainage tube body and affecting the drainage effect.
[0005] By comparing the above existing documents and searching the prior art, the inventor believes that the following problems still exist:
[0006] In the actual operation process, the puncture needle and puncture tube need to be inserted into the patient's body first, and then the puncture needle is pulled out to connect the drainage tube. This process is rather cumbersome, and the puncture tube is not fixed during the docking process between the puncture tube and the drainage tube, which makes it easy to fall off. For this reason, we propose a chest puncture drainage tube to solve the above problems. Utility Model Content
[0007] In view of the deficiencies of the prior art, the utility model provides a thoracic puncture drainage tube, which solves the problem that the puncture drainage process of the prior art is relatively complicated and there is a risk of the puncture tube falling off.

[0011] Furthermore, a fixing tube is installed on the surface of the sleeve, and a sealing head is fixedly installed on one end of the fixing tube away from the sleeve.
[0012] Furthermore, the sealing head can be connected to a syringe, and an inflation component for inflating the airbag is also provided inside the flow guide tube.
[0013] Furthermore, the inflation assembly includes a connecting tube connected to the sealing head, the connecting tube is located inside the fixing tube, and one end of the connecting tube away from the sealing head is connected to the airbag.
[0014] Furthermore, the airbag is embedded in the surface of the guide tube, and the limiting sleeve is located between the sleeve and the airbag.
[0015] Furthermore, an anti-slip sleeve is fixedly mounted on the inner wall of the limiting sleeve, and the anti-slip sleeve is slidably connected to the outer wall of the guide tube.
[0016] Compared with the prior art, the utility model provides a thoracentesis drainage tube, which has the following beneficial effects:
[0017] The chest puncture drainage tube is configured such that the puncture needle is arranged on the inner side of the drainage tube. After the puncture needle is inserted into the patient's chest incision, the drainage tube as a whole can be limited by the air bag and the limiting sleeve. After the effusion is determined by the syringe on one side of the fixed head, the fixed head can be rotated to directly withdraw the puncture needle in one step. Then, the second connector is connected to the first connector by a soft belt, and the patient can be treated by an external water seal bottle, a drainage bag or a negative pressure suction device.
