Utility model content
The technical problems to be solved in the utility model and the technical assignment of proposition are that existing portable negative pressure drainage is overcome to fill
It sets to pass back into the easy bulge needs of air bag influence drainage effect, liquid storing bag there are gas-liquid and frequently empty and leads to inconvenience, provide
A kind of hand presses negative pressure drainage device, and gas-liquid will not occur for the negative pressure drainage device pass back into air bag to influence drainage in, makes
Bulge will not occur with middle liquid storing bag, less empty processing with frequent tapping switch of opening.
The utility model solves the technical solution that technical problem uses: a kind of hand presses negative pressure drainage device, including liquid storing bag,
Air bag and upper and lower adapter tube and connector, the liquid storing bag bottom are equipped with the drain pipe switched with tapping, the lower linking tube both ends point
The next check valve Dui Jie be set at liquid storing bag and air bag and liquid storing bag and lower linking tube docking, air bag is docked at upper connecting tube both ends respectively
With upper check valve is set at connector and air bag and upper connecting tube docking, it is characterized in that position is single in setting at air bag and lower linking tube docking
To valve, the liquid storing bag is equipped with upward hollow extended segment and forms exhaust pipe, and water-stop exhaust valve is arranged on the exhaust pipe.This
Utility model prevents the gas-liquid in lower linking tube from flowing back into air bag by middle position check valve, it is ensured that air bag can produce enough negative pressure
It is drained；Hollow extended segment is arranged on liquid storing bag to form exhaust pipe and water-stop exhaust valve is arranged, it, can when pressing pressuring gasbag every time
The gas in liquid storing bag is outwardly discharged from water-stop exhaust valve by pressure, avoids accumulated gases in making its drum in liquid storing bag
Packet uses more convenient without frequently opening tapping switching evacuation.In addition, top-down three check valve can also play resistance bacterium
Effect prevents bacterium from entering in patient body along lower linking tube and upper connecting tube.
As further improving and supplementing to above-mentioned technical proposal, the utility model uses following technical measures: described
Liquid storing bag two sides are symmetrical arranged exhaust pipe at two.Exhaust pipe can be in Accelerating Removal liquid storing bag at symmetrically arranged two on liquid storing bag
The gas of accumulation, the liquid for making liquid storing bag that negative pressure drainage be received to input rapidly improve negative pressure drainage effect.
Suspended structure is set on the exhaust pipe.Suspended structure on exhaust pipe for provide hanging function and belt or
The collocation of waist button, facilitates sufferer to carry using hand by negative pressure drainage device.
The suspended structure is the hook or lacing hole on exhaust pipe.Suspended structure can be hook or lacing hole and its
Its common suspended structure, wherein hook can very easily direct and belt or waist loop arrange in pairs or groups, lacing hole can be to tie up after wire rope handling
On belt or waist loop.
The lower linking tube is hose, which is provided with flow regulator.Lower linking tube is using hose and installs flow regulator, energy
Drainage speed is effectively adjusted, sufferer drainage needs are met, hand is not had to when drainage device works and presses air bag, as long as complying with patient posture
It is drained by gravity, flow regulator can directly adopt flow regulator common on infusion tube, this is existing
Technology.When drainage device needs hand to do negative pressure drainage by air bag, flow regulator is in normally open.
Aperture is set on the exhaust pipe, water-stop exhaust valve is the resistance mycoderm set on aperture.Aperture on exhaust pipe, block water exhaust
Valve is the resistance mycoderm set on aperture, and resistance mycoderm can block the row of the germ in liquid storing bag memory tank body outwardly, while not shadow
The gas discharge in liquid storing bag is rung, resistance mycoderm is the prior art.
Gas-liquid will not occur in and pass back into air bag, energy after air bag pressing for negative pressure drainage device described in the utility model
It generates enough negative pressure to be drained, the gas in liquid storing bag can discharge in time, and bulge will not occur for liquid storing bag, less
Processing is emptied with frequent tapping switch of opening, sufferer is carried using more convenient.In addition, the utility model cannot be only used for
Hand presses negative pressure drainage, can also comply with patient posture and make gravity drainage.
