Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1, Fig. 2 and Fig. 3 are referred to, the utility model provides a kind of technical scheme：A kind of woven hose of anti-return blood, bag
Liquid flowing tube 2, dropping funnel 5 and injection needle 7 are included, the top of liquid flowing tube 2 is provided with bottle stopper penetration device 1, and the bottom side of liquid flowing tube 2 is set
There is air cleaner 3, the lower section of liquid flowing tube 2 is provided with dropping funnel 5, and the inside of dropping funnel 5 is by 56 groups of liquid storage tube 52 and conical hopper
Into being provided with spherical buoy 53 in dropping funnel 5, and the upper and lower ends of spherical buoy 53 are provided with locating cone bar 55, the bottom of dropping funnel 5
Portion is connected with liquid medicine filter 10 by infusion tube 4, and flow regulator 6 is provided with infusion tube 4, injection needle 7 and medicine
Liquid filter 53 is connected by syringe needle woven hose 9, and the upper end of syringe needle woven hose 9 is provided with stretching flexible pipe 8, infusion tube 4
Diameter be more than syringe needle woven hose 9 diameter.
The top of liquid storage tube 52 is provided with liquid droping port 51, and sectional area is gradually reduced the conical hopper 56 from top to bottom, and
The bottom of conical hopper 56 is provided with liquid outlet 54, and the locating cone bar 55 of the spherical upper and lower ends of buoy 53 is individually positioned in drop
In liquid mouth 51 and liquid outlet 54, the diameter of the spherical buoy 53 is more than the diameter of section of liquid droping port 51 and liquid outlet 54, and drips
The diameter of section of liquid mouth 51 and liquid outlet 54 is more than the maximum cross section diameter of locating cone bar 55, and spherical buoy 53 selects plastic blister
Foam, and the outer surface of spherical buoy 53 scribbles sanitation-grade barrier coat, the bottom of liquid flowing tube 2 is provided with fixed protecting groove 21, and solid
Determine protecting groove 21 for circle, a diameter of 1.8~3.5cm of the fixed protecting groove 21, and the top surface of fixed protecting groove 21 be provided with it is anti-skidding
Rubber, the air cleaner 3 pass through fixed protecting groove 21 to be connected with Shu infusion tube 4.
The operation principle of the present embodiment：Using the anti-return blood woven hose when, the bottle stopper penetration device 1 of woven hose is inserted
In infusion bottle, into the dynamic upper end insertion transfusion liquid bottle by liquid flowing tube 2 of interpolation, make to fix protecting groove 21 and the bottle stopper of infusion bottle is close
Connection, fixed protecting groove 21 can be fixedly connected with the bottle stopper of infusion bottle as needed, avoid patient from making in use defeated
Liquid pipe departs from, and in infusion process, decoction drips downwards under gravity, drips to inside funnel 5, is adjusted by adjusting flow velocity
Device 6 can control the flow velocity of decoction, and when adjusting flow velocity funnel 5 liquid level it is different, but not over or less than leakage
The face height of liquid droping port 51 and liquid outlet 54 on bucket 5, decoction pass through syringe needle woven hose 9 by liquid medicine filter 10, passed through again
Injection needle 7 is connected through human skin tissue with blood vessel, because atmospheric pressure is more than blood flow pressure and decoction is flowed into human body
It is intravascular, when decoction drips off, the spherical buoy 53 in funnel 5 blocks liquid outlet 54, in infusion tube 4 decoction of residual after
Continue to be formed with liquid outlet 54 to spherical buoy 53 during intravascular flow formation pressure differential and be tightly connected, avoid air from entering blood
In, when decoction drip off blood pressure it is larger when blood along infusion tube flow back, taper can be leaked when blood backflow to funnel 5
Bucket 56 fills up now spherical buoy 53 to be blocked liquid droping port 51 and forms sealing and avoid blood from further flowing back causing medical thing upwards
Therefore occur.
