Abstract
The utility model relates to a transfusion system, comprising a transfusion catheter, two needle heads which are respectively positioned at the upper and the lower ends of the catheter, a dropper, a fluid flow regulator, a filter and a joint. The dropper, the fluid flow regulator, the filter and the joint are positioned on the transfusion catheter from top to bottom in sequence. The utility model is characterized in that an injection port for pushing and injecting liquid is arranged in the transfusion catheter between the fluid flow regulator and the filter. Because of the arrangement of the injection port for pushing and injecting liquid, the vein push and injection physic liquid is filtered by the filter and enters an organism in the process of transfusion. So the utility model effectively controls that the particle and the foreign matter in the vein push and injection physic liquid enter in the organism, and the harm for a patient is reduced. With reasonable design and simple structure, the utility model is an ideal transfusion system.
Description
This utility model is a kind of transfusion device that is used for the body transfusion.
Existing transfusion device, only do not have a joint between filter and transfusion catheter lower end syringe needle, when needs carried out intravenous injection in infusion process, injection liquid pushed from joint, microgranule in the injection liquid and foreign body directly enter body, cause certain harm to body.
The objective of the invention is deficiency, provide a kind of intravenous injection liquid that makes also can effectively control microgranule and enter in the body, reduce transfusion device body harm through entering the body blood flow again after the filter filtration at the prior art existence.
This utility model is realized by following design: in the transfusion device that is made of dropper, transfusion catheter, fluid flow regulator, filter, joint, syringe needle, in the transfusion catheter between fluid flow regulator and filter, be provided with one and inject the liquid inlet.In infusion process, when needing the intravenous injection medicinal liquid, injection liquid is by injecting the liquid inlet, and enters body through filter, thereby realizes the purpose of this utility model.
Of the present utility modelly inject the joint that the liquid inlet can adopt plug-in type, also can adopt the osculum of injecting of band cap.
This utility model is injected the liquid inlet owing to be provided with one in the transfusion catheter between fluid flow regulator and filter, make the intravenous injection medicinal liquid by injecting the liquid inlet, and the filtration of process filter enters into body again, controlled microgranule and foreign body intrusion body in the intravenous injection medicinal liquid effectively, reduced harm the patient; It is reasonable in design, and is simple in structure.
Fig. 1 is this utility model structural representation.
Fig. 2 is another example structure sketch map of this utility model.
Be further described for this utility model structure below in conjunction with accompanying drawing: this utility model comprises transfusion catheter 3, lay respectively at the syringe needle 7 of transfusion catheter 3 upper and lower sides, be positioned at successively from top to bottom transfusion catheter 3 dropper 1, fluid flow regulator (2), inject liquid inlet 8, rubber tube 4, filter 5, joint 6.This utility model material of main part adopts polyethylene.
Referring to accompanying drawing 1: inject the joint (8a) that liquid inlet 8 can adopt plug-in type.
Referring to accompanying drawing 2: that injects that the liquid inlet also can adopt the band cap injects osculum (8b).
During use, the syringe needle of this utility model upper end inserts in the infusion bottle, and the syringe needle of its lower end thrusts in the body vein, when needs carry out intravenous injection in infusion process, can easily injection liquid be pushed body from injecting the liquid inlet with syringe.
Claims (3)
1, a kind of transfusion device, comprise transfusion catheter (3), lay respectively at the syringe needle (7) of transfusion catheter (3) upper and lower side, be positioned at dropper (1), fluid flow regulator (2), filter (5), the joint (6) of transfusion catheter from top to bottom successively, it is characterized in that being provided with in the transfusion catheter between fluid flow regulator (2) and filter (5) and inject liquid inlet (8).
2,, it is characterized in that the described joint (8a) that liquid inlet (8) adopts plug-in type of injecting by the described transfusion device of claim 1.
