Respiratory tract negative pressure suction device for emergency nursing

Abstract

The invention discloses a respiratory tract negative pressure suction device for emergency nursing. The device comprises universal wheels, a device shell, a cover plate, a first spring, a pressure cylinder, a piston, a piston rod, a pressing head, a vent valve and the like; a breathing intubation tube on a lengthened breathing tube is inserted into the respiratory tract of a patient, a user presses a pressing head on a pressure cylinder, gas is generated after the piston moves downwards, the cover plate is opened by air pressure, the gas is released, through closure by spring return, the pressing head drives the piston to lift upwards to generate negative pressure, a receiving chamber is connected through a first pipeline, the upper end of the receiving chamber sucks blockages sucked out of the respiratory tract of the patient from the lengthened respiratory tube through a second pipeline and enters the receiving chamber, and a sliding rod is driven to slide left and right through airpressure in an arranged one-way valve, the suction force is generated when the pressing head is lifted to enable a movable block on the sliding rod and the interior of the valve body to be in an openstate, and the other parts are closed to prevent blockage from flowing back.

Description

Technical field: [0001] The invention relates to the technical field of negative pressure suction, in particular to a respiratory negative pressure suction device for emergency care. Background technique: [0002] Excessive airway obstruction will directly lead to hypoxia, suffocation and death of the patient, and its disability and fatality rate is extremely high. If the breathing can be restored in the shortest time, the success rate of treatment will be greatly improved. Negative pressure suction device is used for Suction bleeding, exudate, pus, and the contents of the chest viscera during the operation, so that the operation is clear and the chance of contamination is reduced. The principle of the suction device is very simple, that is, to create a negative pressure state of the suction head through a certain method, so that Atmospheric pressure will squeeze the material outside the suction head to the suction head, so as to complete the "suction" effect. The existing n...

Problems solved by technology

[0003] The purpose of the present invention is to provide a respiratory negative pressure suction device for emergency care in order to solve the above problems, which solves the problem that the existing negative pressure suction device is large in volume, complex in structure, inconvenient to carry, not suitable for emergency use, and can be used at the same time. It is inconvenient to clean after cleaning, and it is easy to cause bacterial growth, and the breathing tube cannot be effectively fixed when the breathing tube is inserted into the respiratory tract, and the deviation will cause damage to the patient's respiratory tract
