The invention relates to the technical field of medical instruments, and provides a closed drainage device, which comprises an outer capsule, an inner capsule, a guide tube and a drainage tube. The outer capsule and the inner capsule are communicated through an opening provided in the inner capsule, one end of the guide tube is communicated with the inner capsule, the other end of the guide tube is extended from the outer capsule, and a first one-way valve for unidirectionally supplying gas or liquid into the inner capsule is provided in the guide tube; one end of the drainage tube communicates with the inner capsule, and the other end of the drainage tube protrudes from the outer capsule and communicates with the external environment; the discharge tube is internally provided with a second one-way valve for unidirectionally guiding gas or liquid out of the inner capsule, the outer capsule is an elastic closed capsule, and the outer capsule can be squeezed to form a negative pressure in the outer capsule and the inner capsule for guiding fluid. The closed drainage device of the invention integrates the functions of venting and liquid collecting, and eliminates the connection between a sealed bottle and a plurality of conduits, so that the structure is simplified, and operation and carrying are facilitated, thereby facilitating early off-bed activities of the patient. The closeddrainage device is suitable for emergency sites and outdoor environments.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a closed drainage device. Background technique [0002] Closed drainage is to put one end of the drainage tube into the diseased part of the patient's body, and the other end is connected to a water-sealed bottle lower than its position, so as to discharge gas or collect fluid in the diseased part, so that the diseased part can restore its function . Taking the closed drainage of the chest cavity as an example, one end of the drainage tube is put into the patient's chest cavity, and the other end is connected to a water-sealed bottle lower than the position, so as to discharge the gas or effusion in the chest cavity, so that the lung tissue can be re-opened. To restore function, thoracic closed drainage, as a treatment method, is widely used in the drainage of hemothorax, pneumothorax, empyema and drainage after thoracotomy, which plays a very important role in the t...
