Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this utility model is made up of syringe 1 etc., the side of described syringe 1 front end surface is provided with a nipple 13, and the through hole in described nipple 13 is connected through with syringe 1, and this syringe 1 open rearward end place is provided with the bending segment 11 that a circle horizontally outward extends along opening edge edge.
Be provided with a columnar projections 12 at the opposite side of described syringe 1 front end surface, the middle part of this columnar projections 12 is provided with opening through hole backwards, and the rear end of this through hole is connected through with syringe 1, a sleeve 2 is provided with in described syringe 1, spacer block 21 is provided with in described sleeve 2, described spacer block 21 is separated into two cavitys sleeve 2, a push rod 22 is equipped with in each described cavity, the front end of each described push rod 22 is equipped with a piston 27, the front end surface of each described cavity is respectively provided with a sleeve pipe 23, each described sleeve pipe 23 is all connected through with the cavity of correspondence position, the shape of through holes of the profile of two described sleeve pipes 23 and the through hole back-end shape of nipple 13 and columnar projections 11 is suitable, two described sleeve pipes 23 are socketed with the open rearward end of nipple 13 and the open rearward end of columnar projections 12 respectively and are connected.
The rear end of described sleeve 2 is arranged with two clips 24, bent brace 25 is equipped with between each described clip 24 and sleeve 2, described clip 24 is provided with draw-in groove towards the side of syringe 1, the width of described draw-in groove and the thickness of bending segment 11 suitable, this draw-in groove and bending segment 11 connect and fix.
As shown in Figure 2, the front opening place of each described sleeve pipe 23 is equipped with three flap valves, 26, three described flap valves 26 and adopts soft silica gel material to make.
Using method of the present utility model is as follows:
As shown in Fig. 1 to Fig. 3, before using, pull the push rod 22 in two cavitys respectively, drive corresponding piston 27 that the medicinal liquid of required transfusion and normal saline are pumped in two cavitys of sleeve 2 respectively, then sleeve 2 is put into syringe 1, and make one of them sleeve pipe 23 on sleeve 2 stretch into nipple 13, another sleeve pipe 23 stretches in the through hole of columnar projections 12, simultaneously, bend two braces 25, draw-in groove on two clips 24 is connected and fixed with the bending segment 11 of correspondence position respectively, so just can fixed muffle 2, prevent sleeve pipe 23 from getting loose from nipple 13, cause the result that medicinal liquid is omitted, nipple 13 cover is received on remaining needle (sign), the push rod 22 promoting cavity corresponding to transfusion medicinal liquid is again infused.
After the medicinal liquid of infusing is totally lost, take off clip 24, pull out one section of sleeve 2, sleeve pipe 23 is made to depart from the through hole of nipple 13 and columnar projections 12, manual rotation sleeve 2, make the corresponding direction, nipple 13 place, cavity side that normal saline is housed, now again the sleeve pipe 23 of correspondence position is put in nipple 13, the be totally lost sleeve pipe 23 of medicinal liquid of opposite side stretches in the through hole of columnar projections 12, repeating aforesaid operations is fixed on clip 24 on bending segment 11 again, after having operated, take off syringe 1 and can carry out have input of next group medicinal liquid.
In the process, the push rod 22 in sleeve 2 and between medicinal liquid without pressure differential, medicinal liquid can not flow out, and the gap between three flap valves 26 of sleeve pipe 23 front end face is little, also can prevent the outflow of medicinal liquid; Because flap valve 26 is made up of soft silica gel material, when promoting push rod 22 and inputting medicinal liquid, flap valve 26 can open under pressure, medicinal liquid is discharged thus, and after push rod 22 has operated, flap valve 26 automatic drawing back becomes original state, reduce pressure differential, also can prevent the situation of medicinal liquid or backflow of blood.
The number of flap valve 26 can adjust according to practical situation, and the present embodiment does not have uniqueness.
It is consistent with prior art that this utility model does not describe part, and therefore not to repeat here.
These are only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
