Gas path blockage prevention device of negative pressure system for hospital

Abstract

The invention discloses a gas path blockage prevention device of a negative pressure system for a hospital. The gas path blockage prevention device comprises a front cover and a rear cover, wherein the rear part of the front cover is internally provided with first internal threads, and the front part of the rear cover is provided with first external threads; the first external threads are matched with the first internal threads, so that the front part of the rear cover can be arranged in the rear part of the front cover; the front end of the first internal threads in the front cover is provided with a filter screen device; the rear end of the filter screen device is in contact with the front end of the rear cover; the middle part of the rear cover is protruded outwards; the protruded middle part is positioned behind the first external threads; a seal ring is arranged between the rear end of the first internal threads and the middle part of the rear cover. Under the condition that the negative pressure system absorbs blood and medical dirt with a small area, the gas path blockage prevention device is capable of realizing effective filtering and cleaning, achieving the blockage prevention effect, and achieving the effects of clear blockage point clearing targets and simplicity and convenient in clearing under the condition that blockage and insufficient air pressure are caused since the negative pressure system repeatedly absorbs the blood and the medical dirt with a small area or large area.

Description

technical field [0001] The invention relates to an anti-airway blocker for a negative pressure system of a hospital, which is mainly used in the negative pressure airway system of a hospital. Background technique [0002] Due to the blockage or serious lack of air pressure caused by blood and medical waste being sucked into the negative pressure system pipeline due to the full bottle of dirt, the negative pressure system cannot be used normally, resulting in unclear blockage points, difficult maintenance and high cost, which seriously affects the operation. The normal use of the room and ICU. At present, there is no similar product in the market that can effectively filter and clean when the negative pressure system inhales blood and medical waste in a small area, so as to achieve the effect of anti-clogging and inhale blood and medical waste in a small area of ​​the negative pressure system multiple times or in a large area. In the case of clogged objects and severe insuff...

[0002] Due to the blockage or serious lack of air pressure caused by blood and medical waste being sucked into the negative pressure system pipeline due to the full bottle of dirt, the negative pressure system cannot be used normally, resulting in unclear blockage points, difficult maintenance and high cost, which seriously affects the operation. Normal use of the room and ICU

At present, there is no similar product in the market that can effectively filter and clean when the negative pressure system inhales blood and medical waste in a small area, so as to achieve the effect of anti-clogging and inhale blood and medical waste in a small area of ​​the negative pressure system multiple times or in a large area. In the case of clogged objects and serious lack of air pressure, the goal of cleaning the clogged point is clear and the cleaning is simple, convenient and low-cost
