Abstract
The utility model relates to a machinery pressure bearing sucking device, which is used for surgical operation, internal medicine and paediatric rescuing operation to the desperate patients in the fields such as clinic surgery, obstetrics and gynecology department and facial features department, etc. the treading type pressure bearing source of the device is connected with an air releasing valve and a single direction air charging valve; the one end of the source is communicated with a pressure bearing bottle of a pressure gauge through an air charging valve of the single direction air charging valve that is communicated with the treading type pressure bearing source. The sucking pipe of a nasal guiding pipe joint is communicated with the pressure bearing bottle, the sucking pipe has an observation pipe and a switch. A piston rod that connects a treading plate is connected with the piston inside the treading type pressure bearing source. The utility model has the advantages of no use of electric power, convenient use, safety and reliability, further avoiding the liquid conducting medical malpractices caused by the power off and electric apparatus faults from taking place.
Description
Technical field
This utility model relates to medical apparatus and instruments, especially a kind of mechanical type negative pressure suction device of using when the heavy patient is rescued in operation such as Clinical Surgery, department of obstetrics and gynecology, department of eye and internal medicine and department of pediatrics of being used for.
Background technology
At present, hospital is used for the negative pressure suction device that uses when the heavy patient is rescued in operation such as Clinical Surgery, department of obstetrics and gynecology, department of eye and internal medicine and department of pediatrics, it is the electric suction apparatus of continuing to use for a long time always, normal can not the use during because of power failure suddenly of this suction pump jeopardized patient's life, in addition, therefore and death by suffocation easily cause motor because of connecting electricity and burn and because of connecting other danger that electricity causes, often motor influences normal rescue work and operation is carried out because of repairing or changing when leaking, many patients.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of non-electric mechanical type negative pressure suction device is provided.
The purpose of this utility model can realize by following technical solution: this device comprises negative pressure source, negative pressure bottle, pressure indicator, wherein foot-operated negative pressure source is connected with one-way exhaust valve and breather cheek valve, the other end of the air inlet pipe that one end is communicated with foot-operated negative pressure source by breather cheek valve be connected with manometric negative pressure bottle and be communicated with, the suction pipe that is provided with the nose catheter adapter is communicated with negative pressure bottle, and suction pipe is provided with observing tube and switch.
The piston rod of above-mentioned connecting pin pedal links to each other with piston in the foot-operated negative pressure source.
When this utility model uses, earlier nose catheter adapter and nose conduit are pegged graft, again pedal is stepped on downwards, when piston rod tractive piston moves down, one-way exhaust valve is closed, and breather cheek valve opens wide, and gas is drawn out of in the negative pressure bottle, when piston stroking upward, one-way exhaust valve opens wide, and breather cheek valve is closed, and repeats, produce powerful negative pressure in the negative pressure bottle rapidly, these negative pressure data are shown by Pressure gauge, when negative pressure acquires a certain degree, open switch, finish the attraction task, and observe color, quantity and the viscosity that is attracted thing from observing tube.
This apparatus structure is simple, does not make electricity consumption, and is easy to use, safe and reliable, energy savings, and can avoid the drain malpractice that causes because of power failure or apparatus failure.
