When described floating block fastener slides onto described limiting section top, described floating block fastener and flap clamping;
When described floating block fastener slides onto bottom described limiting section, described floating block fastener and flap depart from clamping.
By adopting technique scheme, when client need continuously defeated two bottle liquid medicine time, first a bottle liquid medicine is connected with bottle plug puncture unit, switching valve rotates due to fluid pressure, treat floating block fastener because buoyancy floats, switching valve is blocked, transfusion starts, then the second bottle liquid medicine is inserted, can to be automatically switched infusion bottle by the rotation of switching valve, realize unremitting continuous transfusion, alleviate the burden of medical personnel, preventing air enters in patient body or the phenomenon such as blood back, and this project organization simply can be practical.
As concrete technical scheme of the present utility model, described floating block fastener comprises floating block and dop, and described limiting section comprises limit sliding chutes, and the two ends of described limit sliding chutes are equipped with limited block, and described dop is between the described limited block at two ends.
By adopting technique scheme, floating block clamping can due to the upper and lower slippage of the buoyancy of liquid in limit sliding chutes, simultaneously due to the position-limiting action of limited block, avoid floating block fastener floating go out infusion tube or fall in infusion tube, make floating block fastener can block switching valve normally, realize the automatic decanting of syringe.
As preferably of the present utility model, the top of described threeway cavity is provided with and turns hole, and one end of described switching valve is provided with rotating shaft, and described rotating shaft and the described hole that turns are rotationally connected.
By adopting technique scheme, the rotation connection structure of switching valve and threeway cavity is simple, and firmly, manufacturing process is comparatively simple, convenient production.
As preferably of the present utility model, described flap is just provided with sealing member to described infusion tube one end.
By adopting technique scheme, the setting of sealing member can improve the sealing between left chamber and right chamber, prevents from having liquid medicine flow between left chamber and right chamber, impact injection.
Compared with prior art, the utility model has the advantage of: different syringe in the past, can the device of automatic decanting by arranging one, achieve patient when injecting, the automatic switchover of medicine bottle, novel in structural design is simple, practical.

Detailed description of the invention
With reference to accompanying drawing, this utility model transfusion device embodiment is described in further detail.
See Fig. 1, a kind of automatic decanting infusion apparatus, comprise infusion tube 5, described infusion tube 5 is connected with threeway cavity 12, switching valve 2 is provided with in threeway cavity 12, described switching valve 2 comprises flap 21, the upper end of described flap 21 and the roof of threeway cavity 12 are rotationally connected, described threeway cavity 12 is divided into left chamber 3 and right chamber 4 by described flap 21, described left chamber 3 is communicated with respectively with right chamber 4 and is connected with bottle plug puncture unit 1, described infusion tube 5 is provided with limiting section with the junction of threeway cavity 12, described limiting section slippage is connected with floating block fastener 9, the inwall gap of described floating block fastener 9 and described infusion tube 5 is arranged, when described floating block fastener 9 slides onto described limiting section top, described floating block fastener 9 and flap 21 clamping, when described floating block fastener 9 slides onto bottom described limiting section, described floating block fastener 9 departs from clamping with flap 21.
When client need continuously defeated two bottle liquid medicine time, first be connected with bottle plug puncture unit 1 by a bottle liquid medicine, switching valve 2 rotates due to fluid pressure, treats floating block fastener 9 because buoyancy floats, switching valve 2 is blocked, transfusion starts, and then inserts the second bottle liquid medicine, can be automatically switched infusion bottle by the rotation of switching valve 2, realize unremitting continuous transfusion, alleviate the burden of medical personnel, prevent air and enter in patient body or the phenomenon such as blood back, and this project organization simply can be practical.
See Fig. 2, threeway cavity 12 center bottom is connected with infusion tube 5, floating block fastener 9 is arranged in infusion tube 5, the inwall of infusion tube 5 is provided with limit sliding chutes 13 and limited block 11, floating block fastener 9 comprises floating block 14 and dop 10, when there is no liquid, the limited block 11 that the dop 10 on floating block fastener 9 is connected to infusion tube 5 inwall cannot fall.
See Fig. 3, the top of described threeway cavity 12 is provided with and turns hole, and one end of described switching valve 2 is provided with rotating shaft, and described rotating shaft and the described hole that turns are rotationally connected.Switching valve 2 can be rotated around turning hole by rotating shaft in threeway cavity 12, realizes the automatic decanting function of transfusion device.
See Fig. 1 and Fig. 2, when our actual transfusion, first the bottle cork needle in left side is inserted in infusion bottle, after left chamber 3 is full of liquid, switching valve 2 will due to the right chamber 4 of the position-limiting action of floating block fastener 9 cut out and the path of infusion tube 5, then infusion bottle is inserted on right side, when in left chamber 3, liquid reduces gradually, be stressed impact, switching valve 2 can turn clockwise gradually, but due to the setting of middle part floating block fastener 9, at left chamber 3 liquid for before being totally lost, floating block fastener 9 can float always, thus stop switching valve 2 dextrorotation then cause right side liquid to flow into, after left chamber 3 liquid is totally lost, floating block fastener 9 slowly will sink to branched pipe, at this moment due to the pressure of right side liquid, switching valve 2 is turned clockwise, until right chamber 4 is full of medicinal liquid, thus realize the automatic decanting of transfusion device.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under this utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under this utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
