Negative-pressure source of suction device

Abstract

The invention provides a suction apparatus which can uninterruptedly and completely suck liquid gas generated in an operation, can filter impurities and can not cause blockage; the sucked gas liquid containing virus and bacteria is directly discharged outside or into a disinfecting apparatus, so air and environment in a consulting room or a sick room can not be polluted. A filter screen barrel isarranged in the handle tube of a filter or a sucker head; the bottom of the filter screen barrel can be an inclined bottom or a flat bottom; the bottom of the filter screen barrel or the barrel mouthcan face towards a liquid outlet; the filer screen barrel can have a conicity or no conicity; the filter screen barrel can be integraly fixed or movably sleeved in the handle tube; and the tail end of the sucker head is communicated with a pipette. A negative pressure source is a membrane pump provided with a sucking nozzle and a discharging nozzle, wherein the sucking nozzle is communicated withthe pipette; the discharging nozzle is communicated with a bleeder tube; and the membrane pump is connected with a power supply through a power cord and a power joint.

Description

technical field [0001] The present invention relates to a medical device, and furthermore, it relates to a suction pipe head of a medical suction device, a filter device of the suction device and a negative pressure facility of the suction device. Background technique [0002] Now, the aspirator is very frequently important in medical use, and the suction tube of the electric aspirator and the suction bottle are prone to clogging, and although the pneumatic aspirator has a simple structure, it is also prone to clogging. Suction blockage is a common disease of all suction devices, which affects the speed and efficiency of suction, and has a negative impact on treatment. The current suction device needs to extract the air from the sewage collection bottle to form a negative pressure. The suction device relies on the negative pressure to suck out the phlegm, blood and pus. At the same time, the extracted air is directly discharged into the consultation room and ward, which will...

[0002] Now, aspirators are very frequently and important in medical use. The suction tube of the electric aspirator and the suction bottle are prone to clogging. Although the structure of the pneumatic aspirator is simple, it is also prone to clogging.

Suction blockage is a common disease of all suction devices, which affects the speed and efficiency of suction, and has a negative impact on treatment

The current suction device needs to extract the air from the sewage collection bottle to form a negative pressure. The suction device relies on the negative pressure to suck out the phlegm, blood and pus. At the same time, the extracted air is directly discharged into the consultation room and ward, which will pollute the environment and environment. Air
