Description
Technical field
A kind of closed low dose transfusion set is the utility model is related to, belongs to infusion kits technical field.
Background technology
Young infant and neonate give treatment of blood transfusion sometimes during being in hospital, and because its body weight is light, blood transfusion dose requirements are small
And it is accurate, transfusion speed also has strict demand.Again because infusion pump can cause hematoclasis, therefore can only be used in transfusion procedure micro-
Amount syringe pump is transfused, and this just needs to be extracted blood out in advance from blood bag with 60ml syringes is transfused by syringe pump again.First
Extract blood out and be transfused the danger that operation link is more, and pollution risk is big, there is cause children's infection again.
Utility model content
The technical problems to be solved in the utility model is：A kind of closed low dose transfusion set is provided, whole process being capable of shape
Into enclosed blood drawing, blood transfusion system, to avoid pollution, overcome the deficiencies in the prior art caused by first blood-breaking bag before transfusing blood.
The technical solution of the utility model：A kind of closed low dose transfusion set, including blood bag, blood transfusion apparatus, medical three
Port valve, syringe, without filtering extension tube and remaining needle, the blood bag be connected with blood transfusion apparatus, blood transfusion apparatus and without filter extension tube again
It is connected respectively with two interfaces of medical three-way valve, another interface of medical three-way valve is connected with injection needle tube, and no filtering is prolonged
Long tube connects remaining needle, and check valve is provided with the blood transfusion apparatus between blood bag and injection needle tube, is provided with without filtering extension tube
Check valve.
Regulating valve is provided with transfusion device between the blood bag and injection needle tube.
It is described without filtering extension tube on be provided with switch.
The beneficial effects of the utility model are：By in blood bag, blood transfusion apparatus, medical three-way valve, injection needle tube, prolong without filtering
Enclosed transfusion path is set between long tube and remaining needle, and injection needle tube can be by the enclosed suction of blood in blood bag
Go out, and realize that closed is transfused by the conversion of medical three-way valve, the check valve set in the utility model can avoid operating ring
Section excessively and caused by liquid reverse flow pollutes.The utility model is simple in construction, easy to operate, can effectively solve to transfuse blood
Pollution problem caused by preceding first broken bag.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- blood bags, 2- injection needle tubes, 3- remaining needles, 4- medical three-way valves, 5- check valves, 6- blood transfusion apparatus, 7- are opened
Close, 8- is without filtering extension tube.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
With reference to figure 1, the utility model closed transfusion set, including blood bag 1, blood transfusion apparatus 6, medical three-way valve 4, injection needle
Cylinder 2, without filtering extension tube 8, remaining needle 3, blood bag 1 and remaining needle 3 respectively by blood transfusion apparatus 6 and without filtering extension tube 8 with it is medical
Two interfaces connection of triple valve 4, another interface of medical three-way valve 4 are connected with injection needle tube 2.
During blood drawing, rotate medical three-way valve 4, make pipeline communication between blood bag 1 and injection needle tube 2, injection needle tube 2 with without mistake
Pipe sealing between filter extension tube 8, the blood in blood bag 1 is extracted with injection needle tube 2, after extracting good, rotate medical three-way valve
4, make injection needle tube 2 with without being connected excessively between extension tube and remaining needle 3, pipe sealing between blood bag 1 and injection needle tube 2, injecting
Blood in syringe 2 is by that can be patients with transfusion without filtering extension tube 8 and remaining needle 3.
In addition, the utility model can also be between blood bag 1 and injection needle tube 2 transfusion device on installation and adjustment valve, in nothing
Switch 7 is installed in filtering extension tube 8.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model, therefore, the scope of protection of the utility model should be with the power
The protection domain that profit requires is defined.
