The utility model has the advantages of reasonable design, at the infusion in -process, need not not wait for that two stagnant waters of switching press from both sides after the first group liquid medicine infusion, only need to begin to control the sequential control that order that two stagnant waters pressed from both sides switchings can realize two sets of liquid medicines in the infusion, convenience safe in utilization, the operation is swiftly reliably.
Description
Technical field
This utility model be related to it is a kind of can control transfusion order move certainly a bag transfusion device, belong to transfusion instrument field.
Background technology
Venous transfusion is widely used treatment meanss in clinical treatment, and there is the situation of drug combination more, existing
Some Dual-head infusion devices when in use, in order to realize the function of two groups of medicinal liquids of sequential infusions, it is necessary to first only open a bottle stopper and wear
Tongs between thorn device and threeway, after its liquid infusion terminates, closes the tongs, at the same open another bottle plug puncture unit with
Tongs between threeway.Operation is various, adds workload to nursing staff.If after first group of liquid infusion is finished, not in time
Carry out changing bag operation, not only lose time, and transfusion device inner liquid medicine stream can be made empty, make sufferer face the danger of blood vessel embolism.
Utility model content
According to deficiency of the prior art above, the technical problems to be solved in the utility model is：A kind of infusion two is provided
When bottle or two bags of medicinal liquids, it is capable of achieving to automatically control the transfusion device of transfusion order without manual intervention.
It is described in the utility model from moving a bag transfusion device, including dropping funnel and infusion tee, the one of the housing of infusion tee
There are two inlets being connected with infusion tube at end, and the other end has a liquid outlet, is provided with check valve in each inlet.When
Liquid enters infusion tee from the inlet of side, waits when enough liquid is filled with infusion tee, the inlet meeting of opposite side
Closed by liquid.
Using this when bag transfusion device is moved, the tongs on any side infusion tube is first opened, in the side transfusion bag
First group of medicinal liquid Jing homonymy inlet (referred to as A inlets) flow into infusion tee housing, the check valve of homonymy is in current
In the presence of, medicinal liquid path is opened, medicinal liquid is gradually filled with infusion tee, when the medicinal liquid in infusion tee touches opposite side feed liquor
During the liquid outlet of mouth internal check valve, the inlet (referred to as B inlets) of infusion tee opposite side is closed in the presence of medicinal liquid, from
And close the transfusion path of the side.Now, the tongs on opposite side infusion tube is opened, second group in the side transfusion bag
Medicinal liquid will not also enter infusion tee.The state will be always maintained at, until first group of liquid infusion terminates.Now, in B inlets
The suffered top medicinal liquid pressure of check valve exceedes medicinal liquid pressure below and check valve self resistance sum, so as to be turned by closure state
For open mode, second group of medicinal liquid also can be automatically flowed in infusion tee, and the check valve in A inlets is then in the effect of medicinal liquid
The corresponding path of infusing of lower closing, until second group of liquid infusion terminates, it is achieved thereby that the function of two groups of medicinal liquids of sequential infusions.
In this utility model, check valve has various ways, preferably following two in this utility model：
Scheme one：
Described check valve adopts macromolecular material；The liquid feeding end of check valve is normally opened, the periphery of liquid feeding end and feed liquor
The inwall of mouth is fixedly connected；Close in the case of the liquid outlet of check valve is stress-free inside check valve, increasing stressed feelings
Open under condition.The preferred duckbill valve of the check valve, in the case of no pressure inside duckbill valve, its liquid outlet (duck-beak type outlet) is at this
Close up under body elastic reaction；Gradually increase with internal pressure, liquid outlet (duck-beak type outlet) gradually increases, holding liquid can be in height
Discharge under flow velocity.
Scheme two：
Described check valve is thin walled hose made by macromolecular material (such as plastics, rubber etc.), its liquid feeding end
Periphery is fixedly connected with the inwall of inlet or is fixedly connected with the inwall of infusion tube in inlet；The length of thin walled hose
For 1.5～3 times of the bore of inlet.Wherein, the wall thickness of thin walled hose is not more than 0.05mm.By adopting thin walled hose,
In medicinal liquid liquid level uphill process in infusion tee, thin walled hose under buoyancy rises and deforms, entering the side
Liquid end seal is blocked up.
In above-mentioned each check valve, the wall thickness of its liquid feeding end can be designed more than liquid outlet, such as the periphery of liquid feeding end is thickened,
In circular table, such liquid feeding end wall thickness is larger to be easy to fixed, and liquid outlet wall thickness is less easily deformable.
In this utility model, can be by the liquid outlet of infusion tee housing by pipeline and the inlet communication of dropping funnel；
Can directly by the liquid outlet of infusion tee housing and the inlet communication of dropping funnel.For the latter, the housing of infusion tee can be with
Dropping funnel cover split-type connects, it is also possible to the housing of infusion tee is integrally formed with dropping funnel lid, so as to reduce the quantity of part, it is to avoid
Error in assembling process.Check valve, housing and dropping funnel lid can certainly be integrally formed, further reduce the number of part
Amount, it is to avoid the error in assembling process.
This utility model is had an advantageous effect in that compared with prior art：
This utility model reasonable in design, in infusion process, is opened and closed after terminating without waiting for first group of liquid infusion
Two tongses, only need to start to control the sequential control of the i.e. achievable two groups of medicinal liquids of order that two tongses are opened and closed in transfusion,
It is safe and convenient to use, reliability swift to operate.
