Cardiothoracic surgery drainage device with anti-blocking and easily-fixed functions

Abstract

The invention discloses a cardiothoracic surgery drainage device with anti-blocking and easily-fixed functions. The drainage device comprises a drainage bottle, a negative-pressure drainage device anda drainage tube, the drainage tube comprises a puncturing tube and a flow guide tube, an anti-blocking connector is arranged between the puncturing tube and the flow guide tube, a filter screen is arranged in the anti-blocking connector, two ends of the anti-blocking connector are communicated with the puncturing tube or the flow guide tube, a plurality of annular grooves are uniformly formed inthe outer wall of the front end of the puncturing tube, the flow guide tube is connected with the drainage bottle, the negative-pressure drainage device is communicated with the drainage bottle through a negative-pressure tube, a one-way valve is arranged on the drainage tube, a communication direction of the one-way valve is consistent with a drainage direction of the one-way valve, a liquid discharging tube is arranged at the bottom of the drainage bottle, and a liquid discharging valve is arranged on the liquid discharging tube. According to the device, the anti-blocking connector is arranged between drug coatings with anticoagulant materials arranged on the inner walls of the puncturing tube and the flow guide tube, materials such as chippings and fibers can be filtered and interceptedby the filter screen or filter cotton in the anti-blocking connector in the drainage process, and blocking of the drainage tube is prevented.

Description

technical field [0001] The invention relates to the technical field of negative pressure drainage appliances, in particular to a drainage device for cardiothoracic surgery with the function of preventing blockage and being easy to fix. Background technique [0002] At present, for patients with clinical cardiothoracic drainage, closed thoracic drainage is a commonly used treatment method in the field of cardiothoracic surgery. During treatment, the gas and liquid in the patient's chest cavity should be excreted in time. During drainage, a negative pressure suction device is required for suction. During the suction process, the drainage tube is easily blocked, which affects the drainage treatment. At present, the chest drainage tubes widely used clinically are medical silicone tubes with end holes and side holes. In order to keep the chest drainage unobstructed, it is often necessary to squeeze the drainage tubes. The problem of blockage cannot cause a strong flushing effect...
