Problems solved by technology

[0003] Not limited to the above-mentioned disposable negative pressure suction device, there are the following deficiencies: First, due to the negative pressure suction generated by the drainage container itself (before use, the air in the drainage container is driven to the outside), so the negative pressure suction effect is poor The second is that there is a risk of pollution, because the drainage container is in a naked state during use, and if it is not careful, it will be easily damaged and the contents will overflow; the third is that the resource consumption is large and the use cost is high; the fourth is that it is not easy to operate

Embodiment

[0021] See figure 1 and figure 2 , presents a liquid collection bag 1 preferably made of compliant material, such as medical grade polyvinyl chloride or silica gel, which is not limited. A cover 11 is sealed and fixed on the top of the liquid collection bag 1, and a drainage tube interface 111 is extended on the cover 11. The drainage tube interface 111 communicates with the cavity of the liquid collection bag 1 and is drawn from the chest cavity or abdominal cavity of the patient undergoing surgery. The end of the drainage tube is fitted on the drainage tube interface 111 . In other words, one end of the drainage tube is fitted on the drainage tube interface 111 , while the other end fits with the patient's chest cavity or abdominal cavity (put into the chest cavity or abdominal cavity). In order to avoid backflow of the liquid that has entered the liquid collection bag 1, a check valve 1111 is provided at the outlet of the drainage tube interface 111. The check valve ...

Abstract

The invention relates to a negative-pressure drainage device and belongs to the technical field of medical equipment. The negative-pressure drainage device comprises a liquid-collecting bag, wherein a closed cover is arranged on the top of the liquid-collecting bag; and a drainage pipe interface and a liquid discharge interface are arranged on the closed cover. The negative-pressure drainage device is characterized by also comprising a bottle body, wherein a tee joint connected with a negative pressure source is arranged on the bottle body; the tee joint is communicated with a bottle body cavity of the bottle body; the liquid-collecting bag is positioned in the bottle body cavity; the closed cover is matched with an opening part of the bottle body; a negative-pressure suction interface communicated with a bag cavity of the liquid-collecting bag is arranged on the closed cover; one end of a connecting conduit is arranged on the negative-pressure suction interface; and the other end of the connecting conduit is connected with the tee joint in a matched manner. The negative-pressure drainage device has the advantages that: the negative-pressure suction effect can be effectively improved; the liquid-collecting bag can be protected by the bottle body, so pollution caused by accidental damage to the liquid-collecting bag is avoided; resource can be saved and using cost is reduced; and the negative-pressure drainage device is convenient to operate.
