Gravity drive hydrodynamic system depression drainage device
Technical field
The present invention relates to a kind of medicine equipment, specifically a kind of gravity drive hydrodynamic system depression drainage device.
Background technology
For a variety of postoperative patients, the liquid body exudate of wound surface is drawn external or passed through by conventional negative pressure drainage Negative compression minor cut or wound surface of a wound lacuna, is conducive to the healing of wound tissue.This negative pressure drainage requires negative pressure duration length, pressure It is stably and controllable.The operation principle of existing depression drainage device can be divided into two kinds according to power resources, and one kind is to use manually driven The piston tubular type negative pressure generator of negative pressure drainage ball or syringe-like, another born using motor-driven pressure pump type Press generator.The manually driven negative pressure generator duration is short, pressure transient, poor reliability, and due to negative pressure cavity with Liquid storage cylinder uses same container, it is impossible to continuous to use and easily occur cross-infection;The pressure pump type negative pressure generator duration Long, negative pressure cavity and the liquid storage cylinder container that to be respectively adopted two different have prevented the danger of cross-infection, but still suffer from pressure instability Calmly, the problem of poor reliability, once compression pump, which breaks down, will influence the normal work of flow diverter.
The content of the invention
It is an object of the invention to provide the high gravity drive hydrodynamic system of a kind of negative pressure duration length, pressure stability, reliability Depression drainage device.
In order to reach object above, the technical solution adopted in the present invention is:The gravity drive hydrodynamic system depression drainage device includes Fluid reservoir, drainage tube and negative tube on fluid reservoir, the negative tube connect negative pressure generator, the negative pressure generator Including the price fixing and Moving plate being coaxially disposed, the price fixing and Moving plate are vertically disposed disc, and price fixing is fixedly installed, Moving plate The front of price fixing is can be rotatably set in, negative pressure access aperture is provided with the upper end of price fixing, the negative tube is connected to negative pressure and connect Enter on hole, steam vent is provided with the lower end of price fixing, distance of the steam vent away from axle center is less than negative pressure access aperture away from axle center Distance;Negative pressure hole, lower negative pressure hole and air holes on being provided with Moving plate, on stomata, the position correspondence of the upper negative pressure hole Negative pressure access aperture, the position of the lower negative pressure hole is symmetrical with upper negative pressure hole axle center, the position correspondence steam vent of the air holes, institute The position and air holes axle center for stating stomata are symmetrical;Upper shell and lower house are provided with the front of Moving plate, the upper shell covers Cover on upper negative pressure hole and upper stomata, the lower house is covered in air holes and lower negative pressure hole, and upper shell and lower house are paraxial One end of the heart is connected by connecting tube;The upper negative pressure hole, lower negative pressure hole and air holes, the back side of upper stomata are provided with directly Footpath, which is more than in the closure gasket groove in aperture, the closure gasket groove, is provided with sealing ring.
The price fixing is fixedly mounted on support, and rotating shaft is provided with the axle center of the price fixing, and the Moving plate passes through bearing In rotating shaft.
The beneficial effects of the present invention are:The gravity drive hydrodynamic system depression drainage device is driven using liquid gravity, without electric energy, Negative pressure duration length, pressure stability, reliability are high.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the positive structure schematic of Moving plate.
Fig. 3 is Fig. 1 A portions close-up schematic view.
Embodiment
As shown in Figure 1 and Figure 2, gravity drive hydrodynamic system depression drainage device of the present invention includes fluid reservoir 1, installed in fluid reservoir 1 On drainage tube 2 and negative tube 3, fluid reservoir 1 be used for deposit draining fluids, use for convenience, can also be in the bottom of fluid reservoir 1 It is provided with the delivery pipe 11 of valve.The negative tube 3 connects negative pressure generator, and the negative pressure generator includes what is be coaxially disposed Price fixing 4 and Moving plate 5, the price fixing 4 and Moving plate 5 are vertically disposed disc, and price fixing 4 is fixedly installed, and Moving plate 5 is rotatably It is arranged on the front of price fixing 4.Negative pressure access aperture 41 is provided with the upper end of price fixing 4, the negative tube 3 is connected to negative pressure access aperture On 41, steam vent 42 is provided with the lower end of price fixing 4, the distance of the steam vent 42 away from axle center is less than negative pressure access aperture 41 away from axle The distance of the heart;Be provided with Moving plate 5 negative pressure hole 51, lower negative pressure hole 52 and air holes 53, on stomata 54, the upper negative pressure The position correspondence negative pressure access aperture 41 in hole 51, the position of the lower negative pressure hole 52 is symmetrical with the upper axle center of negative pressure hole 51, the lower gas The position correspondence steam vent 42 in hole 53, the position and the axle center of air holes 53 of the upper stomata 54 is symmetrical.The upper negative pressure hole 51, under Negative pressure hole 52 and air holes 53, the back side of upper stomata 54 are provided with the closure gasket groove that diameter is more than aperture, the sealing ring Sealing ring 12 is installed in groove.So, Moving plate 5 is born with the faying face of price fixing 4 in the airtight fit-state that can be slided relatively when upper Pressure hole 51 is with negative pressure access aperture 41 when dock insertion, and air holes 53 docks insertion with steam vent 42, upper stomata 54 and lower bears Closed by price fixing 4 in pressure hole 52;When Moving plate 5 rotates 180 degree, upper stomata 54 rotates to lower section, docks insertion with steam vent 42, Air holes 53 rotates to top and closed by price fixing 4, rotates to top with negative pressure hole 52 at present, docks and pass through with negative pressure access aperture 41 Logical, upper negative pressure hole 51 rotates to lower section and closed by price fixing 4.
As shown in Fig. 2 being provided with upper shell 6 and lower house 7 in the front of Moving plate 5, the upper shell 6 is covered in negative pressure On hole 51 and upper stomata 54, the lower house 7 is covered in air holes 53 and lower negative pressure hole 52, and upper shell 6 and lower house 7 are paraxial One end of the heart is connected by connecting tube 8.Upper shell 6 and lower house 7 form two liquid containers connected with Moving plate 5 respectively, on When housing 6 fills the liquid such as water, the liquid such as water can be gradually flowed in lower house 7 by connecting tube 8, the sky in lower house 7 Gas is discharged by air holes 53 and steam vent 42, after the liquid in upper shell 6 is reduced, in upper negative pressure hole 51 and negative pressure access aperture Negative pressure is produced in 41, fluid reservoir 1 is acted on by negative tube 3;After emptying rate of liquid in upper shell 6, as long as Moving plate 5 is rotated The transposition of 180 degree, upper shell 6 and lower house 7, you can continue to produce negative pressure.
