Percutaneous thoracic puncture closed drainage apparatus

Abstract

The invention discloses a percutaneous thoracic puncture closed drainage apparatus. The apparatus comprises a sheath tube and a drainage tube, wherein, the front end of the sheath tube is a cusp, theside of the cusp is provided with a side hole, the sheath tube is provided with a skin fixator, the sheath tube has double cavities, the rear end of the sheath tube is provided with two furcations, each furcation is communicated with a cavity, the rear end of one furcation is sealed with a heparin cap and the other furcation is connected with the drainage tube. The percutaneous thoracic puncture closed drainage apparatus also comprises a paracentetic needle and a guide wire, wherein the paracentetic needle comprises a needle body, the rear end of the needle body is provided with an interface which is used to be connected with an injector and a tail-hole corresponding to the guide wire, and the guide wire is a metal wire and is matched with the side hole of the sheath tube and the tail-holeof the paracentetic needle. The percutaneous thoracic puncture closed drainage apparatus has reasonable structure, less complication, low cost and simple and safe operation which can be completed byan ICU doctor independently so that the apparatus benefits the rescue of the seriously ill and is applicable to primary hospitals and outpatients.

Description

technical field [0001] The invention relates to a percutaneous puncture thoracic closed drainage device, which belongs to the field of medical equipment. Background technique [0002] In the prior art, the pleural effusion drainage of critically ill patients generally adopts asking the thoracic surgeon to assist in incision and placement of closed pleural drainage, which has the following disadvantages: 1. Incision and drainage are necessary, and the diameter of this drainage device is large, which is more traumatic to the patient. Large, easy to cause secondary bleeding, infection and even easy to cause empyema; 2. There is no scale display around the tube, and the patient who has been drained for a long time may cause the displacement of the drainage tube due to turning over, moving, and agitation, so that the doctor will not adjust the drainage tube in time. The depth of the thoracic cavity cannot be correctly judged, and imaging examinations are often required, which inc...
