Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and particularly relates to a dry thoracic-closed drainage device with a locking tube. The dry thoracic-closed drainage device with the locking tube comprises a drainage tube and a drainage container, and a liquid inlet, a liquid outlet, an air inlet and an air outlet are formed in the drainage container. The dry thoracic-closed drainage device with the locking tube is characterized in that a liquid feeding one-way valve is arranged on the liquid inlet, a liquid discharging one-way valve is arranged on the liquid outlet, an air feeding one-way valve is arranged on the air inlet, an air discharging one-way valve is arranged on the air outlet, the drainage tube is connected with the liquid inlet through a self-locking sealing connecting mechanism, the drainage container is a dry drainage container, and a negative-pressure detecting displaying device capable of detecting and displaying internal pressure of the drainage container is arranged on the drainage container. The dry thoracic-closed drainage device with the locking tube has the advantages that patient carrying is convenient, air leakage cannot be caused by falling, and the sealing performance is good.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a dry cavity-closed drainage device with a locking tube. Background technique [0002] At present, closed cavity drainage is a necessary measure to treat visceral suppuration, traumatic visceral blood stasis, spontaneous visceral gas stasis and discharge effusion clinically. However, there are many inconveniences in the use of the existing closed-cavity drainage tube and device with liquid: 1. The existing closed-cavity drainage device needs to add a large amount of liquid, generally 500-1000 milliliters, to achieve airtightness and facilitate observation of the cavity. The negative pressure value seriously affects the patient's free movement; 2. Because the equipment containing liquid has certain requirements on height and stability, it increases the difficulty of nursing work. Once the equipment is tilted or fallen, the airflow will flow back into the cavity due to air ...
