Description
Technical field
This utility model relates to the transfusion system technical field, particularly relates to a kind of only hydraulic control system device that is used for transfusion system.
Background technology
At present, in infusion process, extensively adopt the transfusion system that has flow controller and end hydraulic control system device clinically to the sick body medical treatment.
As shown in Figure 1,, mainly comprise dropping funnel 10, the pointed joint 60 that is arranged on dropping funnel 10 tops and is communicated with it for a kind of transfusion system of the prior art.Dropping funnel 10 bottoms offer a dropping liquid outlet 12, and are communicated with a mozzle 11 by some dropping liquid outlet 12.Series connection is provided with a flow controller 40 in the mozzle 11, and mozzle 11 ends are connected with syringe needle 50.
In the enforcement of infusion operation, pointed joint 60 is used for being plugged in a drop bottle 70, and the some dropping liquid that will put in the drop bottle 70 flows in the sick body by pointed joint 60, dropping funnel 10, some dropping liquid outlet 12, mozzle 11, flow controller 40, syringe needle 50 one road.Wherein, flow controller 40 is used to control flow, the flow velocity of mozzle 11 mid point dropping liquids, can be regulated voluntarily by medical personnel or patient.
But when infusion finishes, inject sick body for preventing air, must block mozzle 10 immediately, this blocking-up operation realized by closing flow controller 40 in the past.
Therefore, the patient needs to take great energy monitoring voluntarily in the process of carrying out infusion, or requires family members to accompany and attend to.When not having family members to accompany and attend to, more cause medical personnel's workload to strengthen, there is carelessness to fail after a dropping liquid is used up, in time to close flow controller 40 slightly, will cause blood back or make air inject in patient's body the personal safety that jeopardizes the patient.
For this reason, again referring to shown in Figure 1, in the dropping funnel 10 of above-mentioned transfusion system, also be provided with only hydraulic control system device.Should end hydraulic control system device mainly is made up of airtight buoyancy body 20 and sphere film unit 23.Referring to Fig. 2, airtight buoyancy body 20 is made up of lid 21, floating cup 22, and lid 21 has a smooth end face 212.
In infusion process, because the some dropping liquid L from a drop bottle 70 is arranged in the dropping funnel 10, the floatation suspension that ends hydraulic control system device utilization point dropping liquid L dropping funnel 10 in, some dropping liquid outlet 12 above, guarantee infusion process point dropping liquid export 12 unimpeded, put dropping liquid L and can normally export.
When infusing near end, the liquid levels of some dropping liquid L descend gradually in the dropping funnel 10, and only the sphere film unit 23 of hydraulic control system device has stopped up the some dropping liquid and exported 12, have prevented that air from injecting human body, guaranteed the safety of transfusion operation.
As shown in Figure 3, in infusion process, also may take place, because that flow controller 40 is opened is too small, the liquid levels of some dropping liquid L raise gradually in the dropping funnel 10, cause the end face 212 on the airtight buoyancy body 20 to meet with liquid inlet 13 in the dropping funnel 10.Under the equation effect of a dropping liquid L, both are bonded together, and have stopped up liquid inlet 13, cause the some dropping liquid in the drop bottle 70 can't be advanced into dropping funnel 10 smoothly down, need external force that both that are bonded together are separated, cause the difficulty of operation, wasted part-time.
In addition, when transfusion begins to operate or change when operation bottle, careless slightlyly also have contact with end face 212 a sight generation of influence transfusion of liquid inlet 13.
Therefore, those skilled in the art is devoted to develop a kind of structure of avoiding only hydraulic control system device obstruction to live the liquid inlet of dropping funnel always.
