Abstract

The utility model provides a hand negative pressure suction device, belonging to the field of medicine equipment. The molding of the suction device is similar to a gun; the volume is small and the weight is light; especially, one end of an ' L '-shaped connecting rod of a handle is connected with a flexible handle and the other end is sheathed with the end of a piston rod; the length of the connecting rod of a handle is just matched with a piston stroke; an inner cavity of a suction nozzle is in a cone table shape. When the flexible handle is alternatively held, pressed and loosened, a piston is driven to do reciprocal motion under the cooperation of a pressure spring and suction is realized; because the inner diameter of a suction tube and the volume of a liquid collecting bottle can be respectively four millimeters to six millimeters and 150 ml to 1000 ml, the utility model can be made into various specifications.

Description

A kind of manual type vacuum extractor

This utility model provides a kind of manual type vacuum extractor, belongs to technical field of medical instruments.

Traditional keg float pull-type negative-pressure suction pump has been used for many years, needs the special messenger to take charge of operation because of its bulky heaviness, attraction weak effect and in using, so bring multiple inconvenience so that become a big difficult point in the prior art, but limit and can't change because of its structure.

The purpose of this utility model is to overcome the shortcoming in the above-mentioned prior art, the technical scheme of an innovation of brand-new design, the volume that provides a kind of hand-held grip pressure driven plunger back and forth to form vacuum suction to society is little, in light weight, easy to carry, attraction is effective, applied widely, and the manual type vacuum extractor that can be manipulated voluntarily by the patient is to satisfy the demand.

Task of the present utility model is finished according to following technical solution:

This manual type vacuum extractor is chewed with liquid barrier, air inlet, suction catheter, liquid-collecting bottle by flexible handle, fixed handle, handle and connecting rod and cylinder body, piston, stage clip, air valve, intake valve, air inlet and to be formed for the unit piece assembly.Its innovation part is handle and connecting rod is made " L " shape, and the one end connects flexible handle, and the other end is socketed on the termination of piston rod, the proper again and piston stroke coupling of its length; The inner chamber that air inlet is chewed on the cylinder body is a frustum.

The internal diameter of used suction catheter is at 4～6mm on this suction pump, and the liquid-collecting bottle capacity can be made into several specifications and is equipped with a plurality of at 150～1000mL.

The manual type vacuum extractor integral body of this utility model is the pistol shape roughly the same.

Description of drawings of the present utility model:

Fig. 1 is a kind of manual type vacuum extractor overall structure figure of this utility model.

Among the figure: 1 flexible handle, 2 fixed handles, 3 handle and connecting rods, 4 cylinder bodies, 5 steam vents, 6 piston rods,

7 stage clips, 8 pistons, 9 intake valves, 10 air valves, 11 air inlets are chewed, 12 liquid barriers,

13 liquid collecting bottle caps, 14 air inlets, 15 suction catheters, 16 liquid-collecting bottles.

This utility model is done further statement to embodiment in conjunction with the accompanying drawings:

This manual type vacuum extractor as shown in Figure 1, integral body is pistol roughly the same.Flexible handle 1 and fixed handle 2 combine handle, the fixing column cylinder body 4 of bracketing horizontal on it; " L " type handle and connecting rod 3 is placed in the middle, the one end connect flexible handle 1 and the other end fixedly suit on the built-in piston 8 of cylinder body 4, lean out the termination of the piston rod 6 of cylinder body 4, its length just and the stroke of piston 8 be complementary; Be to chew 11 air flues that constitute in the cylinder of column cylinder body 4 anterior local evaginations by the air inlet of air inlet 14 and frustum inner chamber; Chew 11 from air inlet 14 to air inlet, be provided with liquid barrier 12 successively and lead to the duct that connects liquid collecting bottle cap 13 down, the liquid collecting bottle cap is connected with liquid-collecting bottle 16 for 13 times; Pipette 15 1 ends are sleeved on the air inlet 14.The footpath is at 4～6mm within the pipette 15; The capacity of liquid-collecting bottle 16 is at 150～1000mL.In this scope, can make the pipette 15 and the liquid-collecting bottle that are made into multiple vary in size caliber and capacity, also can be made into the disposable appliance that makes, with anti-pollution.The stage clip 7 that this suction pump is sleeved in cylinder body 4 on the piston rod 6 is that remaining part all can adopt plastics to manufacture the steel material.

Manipulating of this suction pump: the liquid level that will attract the mouth of pipe to insert desire attraction is the fluid-tight shape, grip pressure flexible handle 1, drive handle and connecting rod 3 slippage backward, move behind the piston 8 of synchronous related piston rod 6 front ends, this moment, cylinder body 4 interior air were extruded slowly by the steam vent 5 on cylinder body 4 rear walls, and the space that piston 8 the place aheads enlarge gradually forms negative pressure, at this moment, 11 mouthfuls intake valve 9 is chewed in air inlet in order to plug envelope cylinder body 4 anterior frustum inner chambers, removes after under the effect of its both sides pressure reduction and opens.Because suction catheter 15, air flue and liquid-collecting bottle 16 have constituted the closed system of linker to cylinder body 4, after piston 8 moves the rear wall that is labelled to cylinder body 4 and finishes one stroke, lax flexible handle 1, then piston 8 orders about oppositely reach of do down at the elastic force of stage clip 7, the air valve of cylinder body 4 antetheca bottoms plug envelope is opened immediately, and the gas in the cylinder body 4 is gone out by row pressure.And so forth, make in the suction pump system and to form negative pressure, constitute with atmosphere and continue pressure reduction.Like this, the liquid that desire attracts as: the juices of breast, Intraabdominal hydrops, pus, blood, expectorant and other wound face etc. can be under the effect of negative pressure at pressure reduction all, and self-priming skirt 15 imports, and injected liquid-collecting bottle 16 by liquid barrier 12 choked flows, till sucking.

The hand vacuum suction device of the utility model is compared with prior art and is had significant excellent part:

Volume is little and in light weight, attraction is effective is easy to carry again, applied widely, such as hospital ward, field emergency, family The patient all can use juice that attracts pleural effusions and ascites, purulence, blood, phlegm and other wound face etc. Suction tube, collection The liquid bottle can be made into not only the plurality of specifications that varies in size and but also can be disposable product spare, prevent cross-infection, safety and sanitation. This attractor is simple in structure, and except stage clip was steel material, other part all can be plastic injection-moulded making, so manufacture conveniently, With low cost. Easy and simple to handle, patient can use voluntarily.
