Abstract
The utility model discloses a kind of anti-residual remaining needles, are related to field of medical products, provide a kind of remaining needle that can be avoided medicament residue.The liquid line that anti-residual remaining needle includes connection structure and connect with connection structure, connection structure includes the first liquid inlet joint and the second liquid inlet joint, and the angle of the first liquid inlet joint and liquid line is a, and the angle of the first liquid inlet joint and the second liquid inlet joint is b, a is equal to b, a and b and is all larger than 90 °.When transfusion liquid flow to the first liquid inlet joint and the second liquid inlet joint intersection, the trend of oriented second liquid inlet joint flowing, there is flushing action to the second liquid inlet joint, drug in the second liquid inlet joint can be taken out of, fully enters human body conducive to drug in the second liquid inlet joint.
Description
Technical field
The utility model relates to field of medical products more particularly to a kind of anti-residual remaining needles.
Background technique
Common remaining needle is as described in Figure 1, connect including connection structure, the liquid line connecting with connection structure and with liquid line
Needle portion.Connection structure includes the first liquid inlet joint and the second liquid inlet joint, and the first liquid inlet joint and liquid line are in same
On one straight line, the angle of the second liquid inlet joint and the first liquid inlet joint is acute angle.Being connected separately in two liquid inlet joints can be mutual
The end cap and calparine cap changed.When using being infused with infusion apparatus thread connecting mode, end cap is removed, by infusion apparatus and liquid inlet joint spiral shell
Line connection.When being infused using infusion apparatus needle inserted mode, infusion apparatus needle is inserted into calparine cap.
When amount of infusion is big, it is often that infusion apparatus is threadedly coupled with the first liquid inlet joint, when needing to additionally incorporate drug, will injects
The calparine cap that device needle is inserted into the second liquid inlet joint is injected.After the administration of second liquid inlet joint, drug be easy to remain in second into
In liquid connector, transfusion liquid is flowed to perfusion tube direction without inversely flowing to the second liquid inlet joint direction, therefore can not be incited somebody to action
Drug is taken away in second liquid inlet joint.Difficulty avoids drug in the second liquid inlet joint carrying out washing pipe using the first liquid inlet joint
Residual.When especially giving small dose drug (1ml or so), medicament residue can not fully enter human body, influence effect of drugs, with
As for sterile dispensing liquid washing pipe again must be used, increase workload of the nurse.And it actually in most cases, is easy to ignore
This details does not carry out sterile liquid washing pipe, causes dose insufficient.And the medicament residue time is too long it is also possible to will increase
Infection risk.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of remaining needle that can be avoided medicament residue.
In order to solve the above problem the technical solution adopted is that: anti-residual remaining needle include connection structure and with connection structure connect
The liquid line connect, connection structure include the first liquid inlet joint and the second liquid inlet joint, the angle of the first liquid inlet joint and liquid line
For a, the angle of the first liquid inlet joint and the second liquid inlet joint is b, and a is equal to b, a and b and is all larger than 90 °.
Further, a=b=160 °.
Further, connection structure expands to be formed in the part on the first liquid inlet joint with the second liquid inlet joint intersection point periphery
Fluid reservoir.
Further, fluid reservoir is made of elastic material.
Further, the shape of fluid reservoir is circle.
Further, be connected with calparine cap in the second liquid inlet joint, calparine cap includes interconnecting piece and with flexible sealing
The sealing of part, flexible seals are 0~1mm at a distance from interconnecting piece.
The beneficial effects of the utility model are: transfusion liquid flow to the first liquid inlet joint and the second liquid inlet joint intersection
When, the trend of oriented second liquid inlet joint flowing, i.e. liquid has the component to the second connector direction, has to the second liquid inlet joint
Flushing action can be continuously carried out drug in the second liquid inlet joint, fully enter human body conducive to drug in the second liquid inlet joint.No
When infusion, using the first liquid inlet joint by injection sterile liquid washing pipe, fluid pressure is bigger, it is easier to go out quickly second into
Drug in liquid connector.It can be seen that the utility model can be avoided medicament residue, so that drug is enough, guarantee therapeutic effect；Nurse is not
Washing pipe must be carried out, workload of the nurse is reduced；Also avoid medicament residue time long possible risk.
Detailed description of the invention
Fig. 1 is existing containing needle structure figure；
Fig. 2 is a kind of anti-residual containing needle structure figure；
Fig. 3 is another anti-residual containing needle structure figure；
Fig. 4 is calparine cap structure chart；
In the figure, it is marked as connection structure 1, the first liquid inlet joint 11, the second liquid inlet joint 12, fluid reservoir 13, liquid line 2,
Calparine cap 3, interconnecting piece 31, sealing 32, flexible seals 33, end cap 4.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Fig. 2, anti-residual remaining needle includes connection structure 1 and the liquid line connecting with connection structure 12, connection knot
Structure 1 includes the first liquid inlet joint 11 and the second liquid inlet joint 12, and the angle of the first liquid inlet joint 11 and liquid line 2 is a, first into
Liquid connector 11 and the angle of the second liquid inlet joint 12 are b, and a is equal to b, a and b and is all larger than 90 °.
When transfusion liquid flow to the first liquid inlet joint 11 and the second 12 intersection of liquid inlet joint, oriented second liquid inlet joint
The trend of 12 flowings, has flushing action to the second liquid inlet joint 12, can take drug in the second liquid inlet joint 12 out of, is conducive to second
Drug fully enters human body in liquid inlet joint 12.
The a and b the big more is conducive to liquid and enters liquid line 2 and the second liquid inlet joint 12, but crosses conference and make liquid line 2 and the
Two liquid inlet joints 12 are leaned on close.Comprehensively consider, determines a=b=160 °.
Human body is fully entered in order to further be conducive to drug in the second liquid inlet joint 12, as shown in figure 3, connection structure 1 exists
It expands to form fluid reservoir 13 in the part on 12 intersection point periphery of the first liquid inlet joint 11 and the second liquid inlet joint.This connects the second feed liquor
First 12 narrow part greatly shortens, and reduces the space of remaining drug.Simultaneously as nearby amount of liquid is big, also it is conducive to residual medicine
Object is dissolved into liquid.
Further, fluid reservoir 13 is made of elastic material.Fluid reservoir 13 can be squeezed in this way, improve liquid to remaining medicine
Object scouring effect squeezes out conducive to by remaining drug.Elastic material specifically can be flexible plastic material.Fluid reservoir 13
Shape is preferably round.
Calparine cap 3 includes interconnecting piece 31 and the sealing 32 with flexible seals 33.As shown in Figure 1, conventional heparin cap
It is longer, left drug is equally understood in calparine cap.In order to which drug fully enters human body, remaining drug in calparine cap is preferably reduced, is answered
Reduce calparine cap length.It can be used and minimize mode of the flexible seals 33 at a distance from interconnecting piece 31 to reduce calparine cap long
Degree, flexible seals 33 can be reduced at a distance from interconnecting piece 31 to 0~1mm.
