Specific embodiment
The present embodiment provides a kind of technical solutions:
As shown in figures 1-4, a kind of infusion apparatus with pressurization function, including perfusion tube 1 and pressurizing device, pressurization dress
It sets including receiving pipe 2 that is hollow and being connected with perfusion tube 1, accommodates 2 side wall of pipe and be communicated with liquid inlet joint 29, accommodate pipe 2 and be equipped with
Pressurizing piston 28 accommodates pipe 2 equipped with preventing the medical fluid in perfusion tube 1 to be back to the unidirectional opening and closing valve at liquid inlet joint 29, unidirectionally
Opening and closing valve is set to 29 lower section of liquid inlet joint.
In the present embodiment, liquid inlet joint 29 is connected with infusion bottle, and medical fluid is flowed by liquid inlet joint 29 and accommodated in pipe 2,
And it is flowed in the wounded's body by unidirectionally opening and closing valve.When medical staff needs to carry out pressure transfusion operation, by pressurizing piston 28, take out
It tries to please the medical fluid received in pipe 2, due to unidirectionally opening and closing the effect of valve, the medical fluid in perfusion tube 1 being connected with the wounded will not occur
Reflux, avoids pressurizing piston 28 during extraction, blood backflow is into perfusion tube 1.Medical staff can by aforesaid operations
It realizes and adjusts transfusion speed, operation is very easy, and is not pressurizeed by air to medical fluid, relatively sanitary.
As shown in figure 3, when the medical fluid accommodated in pipe 2 is flowed by the pressure or medical fluid of pressurizing piston 29 by liquid inlet joint 29
When, medical fluid generates pressure to plug 25, then plug 25 squeezes elastic component 24, and medical fluid is from the opening and closing hole on isolation board 26 through fixed plate
Limbers 220 on 22 flows in the vein of the wounded.It is hydraulic that plug is pressed into opening and closing when medical staff pulls up pressurizing piston
In the air, then the suction that the medical fluid in perfusion tube 1 not will receive pressurizing piston 29 flows back, while also avoiding in the wounded's blood vessel
Blood flow back.Therefore, when medical staff pulls up pressurizing piston 29, the medical fluid in infusion bottle can be connect through feed liquor rapidly
First 29 flow into receiving pipe 2, so that medical fluid is accelerated injection the wounded again by pressurizing piston 29 is pushed down on by medical staff
Intravenously.
As shown in figure 3, fixed plate 22 is equipped with fixed ring 23, elastic component 24 is spring, and spring is arranged in fixed ring 23.
As shown in Fig. 2, accommodating 2 inner sidewall of pipe is fixed with imbibition bucket 27, imbibition bucket 27 is located at the lower section of pressurizing piston 28.
As shown in Fig. 2, pressurizing piston 28 is equipped with the operation shank 280 for facilitating medical staff to exert a force.
Lid 20 is equipped backwards to 1 one end of perfusion tube as shown in Figure 1, accommodating pipe 2.
In the present embodiment, lid 20 is connected through a screw thread with pipe 2 is accommodated.
