Abstract

The invention provides a backflow prevention infusion tube which comprises a puncture outfit, a drip chamber, a flow regulator, a medicating tee-joint, a needle base, an injection needle and a pipeline. A backflow prevention film is arranged on the infusion tube, the backflow prevention film is of a circular-arc structure, and an arc-shaped protrusion faces towards the flowing direction of injection fluid, and a cross-shaped seam is formed in the arc-shaped protrusion of the backflow prevention film. The backflow prevention film is adopted in the blood return prevention device, the structure is reasonable, and the purpose of blood return prevention is achieved; in addition, the blood return prevention effect is good, medical safety is guaranteed, pains of patients are alleviated, and unnecessary medical disputes can be avoided; the backflow prevention film is arranged in the needle base, and waste of medical liquid is avoided.

Description

Anti-reflux infusion pipe
Technical field
The present invention relates to a kind of transfusion device, particularly a kind of Anti-reflux infusion pipe.
Background technology
Infusion set is widely used in the slow infusion treatment of patient or operation process, and existing general transfusion device because not changing in time transfusion bottle or pulling out pin, tends to occur the situation of backflow of blood, i.e. blood back phenomenon after liquid is carried.Because blood is in pipeline, clotting mechanism can be activated very soon, causes thrombosis, and the serious malpractice such as nosocomial infection, septicemia even can occur pipe blocking, has increased patient's misery, causes unnecessary medical tangle.Although more existing transfusion devices are also provided with blood return preventer, this class transfusion device is not that blood return preventer complex structure, cost are high, is exactly that blood return prevention effect is bad, and practicality does not reach ideal effect.
Summary of the invention
The present invention proposes a kind of Anti-reflux infusion pipe, solved the problem that transfusion device of the prior art can not anti-return blood phenomenon.
For achieving the above object, the technical solution used in the present invention is: a kind of Anti-reflux infusion pipe, comprise perforator, dropping funnel, flow regulator, dosing tee T, needle stand, injection needle and pipeline, described tube for transfusion is provided with counterflow-preventing film, described counterflow-preventing film be arc-shaped structure and arc convex towards transfusion liquid flow direction, the arc convex place of described counterflow-preventing film is provided with designated port.
Related content in technique scheme is explained as follows:
1,, in technique scheme, described counterflow-preventing film is located in described pipeline.
2,, in technique scheme, described counterflow-preventing film is located in described dropping funnel.
3,, in technique scheme, described counterflow-preventing film is located in described needle stand.
4,, in technique scheme, described counterflow-preventing film is elastic material membrane.
5,, in technique scheme, described elastic material membrane is preferably pellosil.
6,, in technique scheme, described designated port is cross designated port or in-line designated port.
Due to the utilization of technique scheme, the advantage that the present invention compared with prior art has is:
Blood return preventer of the present invention adopts counterflow-preventing film, rational in infrastructure, reach anti-return blood object, and blood return prevention is effective, has ensured medical safety, has alleviated patient's misery, avoids unnecessary medical tangle; Counterflow-preventing film is located in needle stand, has avoided the waste of medicinal liquid.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of Anti-reflux infusion pipe embodiment 1 of the present invention;
Fig. 2 is the structural representation of Anti-reflux infusion pipe embodiment 2 of the present invention;
Fig. 3 is the structural representation of Anti-reflux infusion pipe embodiment 3 of the present invention;
Fig. 4 is the structure for amplifying schematic diagram of counterflow-preventing film in Anti-reflux infusion pipe embodiment 1,2,3 of the present invention;
Fig. 5 is the plan structure schematic diagram of counterflow-preventing film shown in Fig. 4.
In above accompanying drawing: 1, perforator; 2, dropping funnel; 3, flow controller; 4, dosing tee T; 5, injection needle; 6, pipeline; 7, counterflow-preventing film; 8, needle stand; 9, two is logical; 10, public spiral; 11, female spiral.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment mono-:
As shown in Figure 1, a kind of Anti-reflux infusion pipe, comprise that perforator 1, dropping funnel 2, flow regulator 3, dosing tee T 4, needle stand 8, two is logical 9, male spiral 10, female spiral 11, injection needle 5 and pipeline 6, in described pipeline 6, be provided with counterflow-preventing film 7, described counterflow-preventing film 7 is that arc-shaped structure and arc convex are towards transfusion liquid flow direction.
As shown in Figure 4, Figure 5, the arc convex place of described counterflow-preventing film 7 is provided with cross designated port.Described counterflow-preventing film 7 preferably adopts silica gel elastomeric material to make.
Embodiment bis-:
As shown in Figure 2, be: described counterflow-preventing film 7 is located in dropping funnel 2 with the structure difference of embodiment mono-, designated port is in-line designated port.Other structures are identical with embodiment mono-, repeat no more here.
Embodiment tri-:
As shown in Figure 3, and be with the structure difference of embodiment mono-and embodiment bis-: described counterflow-preventing film 7 is located in needle stand 8, near injection needle 5, can the most effectively avoid liquid waste.Other structures are identical with embodiment bis-with embodiment mono-, repeat no more here.
The present invention in use, due to the pressure of liquid, opens the cross crotch of counterflow-preventing film 7, liquid communication; When medicinal liquid drips off, the pressure of air is not enough to cross crotch to open, and the pressure in human body cannot make the cross designated port reverse opening of counterflow-preventing film 7 simultaneously, has avoided the generation of blood back phenomenon, can there is not the risk that patient's health of human body is caused to significant damage, avoid doctor-patient dispute.
More than show and described ultimate principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
