Description

Multifunction device for continuous taking in & injecting medicine

This utility model relates to a kind of multi-functional continuous suction and injection device, belongs to the apparatus that the auxiliary injection device carries out continuous suction liquid.

In the treatment of prison bed, finish the injection and the sucking-off of some liquid, syringe still is a kind of medical apparatus and instruments that is commonly used at present, but because the restriction of structure, in some therapeutic process, also there is certain weak point, as when the relatively large liquid of suction, extremely require great effort when using jumbo syringe to inject with pumping liquid, therefore at present labour-saving small volume syringes of using more, but need carry out repeatedly inspiration and release, this operates each time and syringe is unloaded down from needle stand install again, and is very loaded down with trivial details, and operation can not link up intermittently, waste time and energy, at least wanting two people to operate just can finish, and often makes utensil and liquid contaminated easily, even causes malpractice.

In view of this, the purpose of this utility model is to provide a kind of suction apparatus that can carry out suction liquid continuously, carries out successive suction operation with the auxiliary injection device, to overcome the deficiency of prior art.

The purpose of this utility model is achieved in that

Agent structure of the present utility model is one " T " tee fitting T skeleton, liquid injection pipe is positioned at the front portion of tee T, there is an inserted sleeve its termination, one check valve is arranged in the pipe, the suction body is at the rear portion of tee T, its end is provided with the syringe nipple socket, the side of tee T is a pipette, one check valve is also arranged in the pipe, but the installation direction of the check valve in this check valve and the liquid injection pipe is opposite, after connecting syringe, draw and push away syringe piston, make to form in the tee T and bear, malleation, the alternative opening and closing of check valve in pipette and the liquid injection pipe are inhaled into liquid continuously and release.

Check valve used in this utility model is preferably used tubular valve, is convenient to install, and the form of valve can be multiple.

Below in conjunction with embodiment and accompanying drawing thereof this utility model is described further.

What accompanying drawing 1 provided is structural representation of the present utility model (user mode).

Fig. 2 is the sketch map of check valve pipe 5.

As shown in Figure 1, main body framework of the present utility model is the threeway tubulose, three parts communicate with connection and punish the boundary, the front portion is a liquid injection pipe 7, its front end is an inserted sleeve, in order to union joint sword-shaped needle 8, the cecum check valve pipe made from the polyethylene from high pressure process material 5 is forward arranged in pipe, quality is softer, high resilience has two cracks parallel with axis 6 on the tube wall, its tangent plane is very smooth, involutory very tight, be closed condition at ordinary times, one of its opening pastes securely and is stuck on the three-way tube wall, between this valve pipe and the three-way tube wall certain interval is arranged, liquid is passed through, the rear portion of tee T 4 is shorter, is suction body 3, and end is a syringe nipple socket 2, in order to link the syringe 1 of all size, the side of tee T is a pipette 9, and its front end is an inserted sleeve, also have in the pipe one with liquid injection pipe 7 in identical unidirectional tubular valve, but its cecum is inside, and pipette 9 connects liquid containing bottle 11 by sebific duct 10.

During use, by drawing the piston that pushes away syringe 1, in tee T 4, form negative pressure and malleation, because unidirectional pipe valve 5 has elasticity, the crack of ftractureing very little, can make in the pipette 9 and the crack of the unidirectional pipe valve in the liquid injection pipe 7 is in and opens and closure state, liquid flows in the suction body 3 from liquid containing bottle, the pushing syringe piston is malleation in the tee T, the check valve pipe closing of fracture in the pipette, open in check valve pipe crack in the liquid injection pipe 7, liquid is pushed in the scalp acupuncture, and continuous like this drawing pushes away, and realizes continuous suction operation.

Continuous suction and injection device of the present utility model can connect the utensil with difference in functionality respectively according to different treatment objectives and carry out the suction operation, through experiment, it can be mainly used in: 1, the intravenous injection of relatively large medicament, operation when 2, being used for relatively large hydrothorax of extraction and ascites, it can realize finishing the continuous suction of big quantity of fluid simultaneously, save the time, improved the speed of vasopressing injection, prevented the generation of operational pollution; Be the convenient and reliable apparatus that is used to finish the multiple operations such as suction of intravenous injection, the quick intravenous injection of pressurization and hydrothorax, ascites, and simple to operate, and safety is time saving and energy saving.

The applicant has carried out the contrast experiment in clinical treatment:

In clinical treatment to 30 routine acute angle closure glaucoma and the acidosic patients of 42 example dehydrations, give 20% mannitol and each 250ml of 5% soda intravenous injection of pressurizeing respectively, wherein respectively half is respectively to inject air pressurized and to use continuous suction and injection device pressurization carrying out intravenous injection to contrast in infusion bottle, and a kind of method on average shortens the time about 1/2 than preceding a kind of method behind the result; Heat source response has descended 13.9%.Cross and do intravenous injection, take out hydrothorax, ascites and need two people operation, now use suction and injection device after, generally only need one man operation.It is easy to operate that the medical worker generally feels to use suction and injection device, safety.

Claims (2)

1, a kind of continuous suction and injection device, comprise the suction body in the structure, liquid injection pipe and pipette, it is characterized in that the front portion of liquid injection pipe 7 at one " T " tee fitting T skeleton, there is an inserted sleeve its termination, one check valve 5 is arranged in the pipe, suction body 3 is at the rear portion of tee T, its end is provided with syringe nipple socket 2, and the side of tee T is a pipette 9, and a check valve is also arranged in the pipe, but the installation direction of the check valve 5 in this check valve and the liquid injection pipe is opposite, after connecting syringe, draw to push away syringe piston, make to form in the tee T and bear, malleation, the alternative opening and closing of check valve in pipette 9 and the liquid injection pipe 7 are inhaled into liquid continuously and release.
