Description
Technical field
The present invention relates to a kind of manual negative pressure aspirator, belong to medical instruments field.
Background technology
Suction pump is the medical apparatus commonly used that the doctor undergos surgery, the various secretions that it can attract the patient to overflow in operation process, thereby guarantee that operation can be smoothly, the carrying out of success, reduce patient's pain simultaneously, common suction pump has electric suction apparatus and pneumatic suction pump on the market now, its attraction of electric suction apparatus is effective, but its volume is big, comparatively heavy, move extremely inconvenient, and it needs power supply for its work, in case just running into when having a power failure can't operate as normal, can cause immeasurable influence this moment to patient's life, influenced its range of application; Though pneumatic suction pump has conveniently moving, is not subjected to advantage such as place restriction than electric suction apparatus, its captivation is non-adjustable, can not regulate the size of captivation according to actual needs, thus the carrying out smoothly of influence operation.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of easy to carry, manual negative pressure aspirator that captivation is adjustable.
Technical scheme of the present invention is: the present invention is made up of suction catheter, liquid containing bottle, depression generator, handle, and handle top is provided with the negative pressure control apparatus that links to each other with depression generator.
Suction catheter is connected with liquid containing bottle, depression generator by the cartridge cap of a joint and a threeway, is provided with active page plate, retaining liquid valve and defecator between suction catheter and the reservoir successively.
Depression generator comprises negative pressure cylinder and cylinder body closing cap, the cylinder body closing cap is connected with suction catheter by cartridge cap, the cylinder body closing cap is provided with air inlet and chews and unidirectional air outlet valve, establish the piston that can slide in the negative pressure cylinder within it, the outer sheathed back-moving spring of piston rod, piston rod is connected with handle by a driving handle.
Handle comprises flexible handle and fixed handle, and flexible handle is connected with fixed handle by a connecting rod is rotating, and fixed handle is provided with the counter sink that realization is connected with the driving handle that is provided with drive link.
Negative pressure control apparatus comprises that one is arranged on the adjustable knob of fixed handle upside afterbody, adjustable knob is connected with piston rod, driving handle by a control valve that is connected with it, the connecting portion of control valve is a square shape, and it is one to have the stepped of multilamellar level with the contact site that piston rod contacts with driving handle.
The present invention has increased negative pressure control apparatus, can regulate the negative pressure degree of depression generator as required, and then regulate the size of captivation, can be adjusted to appropriate captivation according to actual needs, make suction pump reach ideal duty, carry out smoothly to guarantee operation.

The specific embodiment
The present invention will be described further in conjunction with the accompanying drawings
The present invention is made up of suction catheter 24, liquid containing bottle 22, depression generator, handle, and handle top is provided with the negative pressure control apparatus that links to each other with depression generator.Suction catheter 22 is connected with liquid containing bottle 22, depression generator by the cartridge cap 14 of a joint 23 and a threeway, is provided with active page plate 13, retaining liquid valve 12 and defecator between suction catheter 24 and the reservoir 22 successively.Depression generator comprises negative pressure cylinder 8 and cylinder body closing cap 10, cylinder body closing cap 10 is connected with suction catheter 24 by cartridge cap 14, establish unidirectional intake valve 9 and air outlet valve 11 on the cylinder body closing cap 10, establish the piston 5 that can slide in the negative pressure cylinder 8 within it, the outer sheathed spring 7 of piston rod, piston rod is connected with handle by a driving handle 19.Handle comprises flexible handle 21 and fixed handle 1, and flexible handle 21 is connected with fixed handle 1 by a connecting rod 20 is rotating, and fixed handle 1 is provided with the counter sink that realization is connected with the driving handle 19 that is provided with drive link 18.Negative pressure control apparatus comprises that one is arranged on the adjustable knob 2 of fixed handle 1 upside afterbody, adjustable knob 2 is connected with piston rod, driving handle 19 by a control valve that is connected with it 4, the connecting portion of control valve 4 is a square shape, and it is one to have the stepped of multilamellar level with the contact site that piston rod contacts with driving handle 19.
When the present invention works, pin flexible handle 21 backward by, flexible handle 21 rotates by connecting rod 20, the U type groove on its top is stirred driving handle 19 and is rotated, the piston rod of the U type groove on driving handle 19 tops promotion in like manner moves forward, the air of negative pressure cylinder 8 front space is forced out the formation negative pressure by air outlet valve 11, after piston 5 moves to forward most position, the elastic force of the spring 7 by being set in the piston rod outside moves it backward, suction catheter 24 and negative pressure cylinder 8 are chewed the gas passage of a sealing of 9 formation by air inlet, and by being arranged on venthole 25 air-outs on the fixed handle 1, thereby form successive negative pressure, like this suction catheter 24 continuable secretions by active page plate 13, retaining liquid valve 12, connect rubber tube 15, strainer valve 16, the effect of filter 17 is attracted in the liquid containing bottle.
In order to regulate the size of captivation, rotatable adjustable knob 2, be provided with groove in the adjustable knob 2, the connecting portion of control valve 4 and adjustable knob 2 is provided with the projection with groove fit, control valve 4 is connected with adjustable knob 2 by the circular hole that is arranged on fixed handle 1, control valve 4 also rotates thereupon, make driving handle 19, the contact position of piston rod and control valve 4 changes, making piston 5 can move to aftermost position changes, the movement travel of piston 5 changes, and negative pressure changes, and the captivation size changes thereupon, thereby can adjust the captivation size according to actual needs, make suction pump be in optimum Working.
