Description
Technical field
The utility model is related to a kind of remaining needle, especially a kind of adjustable remaining needle of access.
Background technology
Inpatient usually needs infusion treatment, is advocated mostly using venous detaining needle in clinical, can be effectively less quiet
Arteries and veins is scorching, decreases and punctures the pain caused by patient repeatedly, and most common remaining needle is exactly Y type remaining needles in clinic；
Existing Y types remaining needle is as shown in Figure 1, including syringe needle 1, conduit 2, clip 3, breeches joint 4；The feed liquor of syringe needle 1
2 one end of mouthful connecting conduit, 2 other end of conduit connect the outlet end of breeches joint 4, match that there are one sealing cap 5 and one on breeches joint 4
Calparine cap 6；Sealing cap 5 and calparine cap 6 are connected on two liquid feeding ends of breeches joint 4；Calparine cap 6 is used to connect woven hose；
But there is easy blood back in remaining needle；The liquid feeding end of nurse from the breeches joint 4 of connection calparine cap 6 carries out washing pipe
When, then washing pipe can be caused not cleaning another liquid feeding end of blood rinse-back to breeches joint 6, residual blood is caused to nourish bacterium, shape
Into blood particle, hang water next time and enter formation thrombus in vivo, it is very harmful.
Invention content
For the deficiencies in the prior art, the utility model provides a kind of adjustable remaining needle of access, and employing can
Threeway then can be closed an access so that be in all the way with patient's vein at washing pipe, such washing pipe by the threeway of adjusting during washing pipe
It avoids blood and rushes not cleaning, remaining risk.The technical solution adopted in the utility model is：
A kind of adjustable remaining needle of access, including syringe needle, conduit, clip, mainly thes improvement is that, further includes one
Threeway；
The threeway includes adjuster, the first liquid feeding end, the second liquid feeding end, outlet end；
Inlet connecting conduit one end of syringe needle, the outlet end of the other end connection threeway of conduit；Clip is arranged on conduit
On；
The adjuster includes three instruction units, and each instruction unit corresponds to a liquid feeding end or outlet end for threeway；Respectively refer to
Show intercommunication between each end of the threeway pointed by portion.
Further, the instruction unit of adjuster is equipped with arrow.
The utility model has the advantage of：
1）By being furnished with the threeway of adjuster, containing needle structure is optimized, blood back can be effectively reduced and rush not cleaning or return
The problem of blood is remaining ensures the safety of patient.
2）The workload of nursing staff can be clinically reduced, and more meets clinical remaining needle operating specification.
Description of the drawings
Fig. 1 is the structure diagram of existing Y types remaining needle.
Fig. 2 is the structure diagram of the utility model.
Fig. 3 is another use state diagram of the utility model.
Specific embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
The adjustable remaining needle of access provided by the utility model, as shown in Fig. 2, including syringe needle 1, conduit 2, clip 3, threeway
4；
The threeway 4 includes adjuster 41, the first liquid feeding end 42, the second liquid feeding end 43, outlet end 44；
2 one end of inlet connecting conduit of syringe needle 1, the outlet end 44 of the other end connection threeway 4 of conduit 2；Clip 3 is set
On conduit 2, when necessary, conduit 2 can be clamped；
The adjuster 41 includes three instruction units 45, and each instruction unit 45 corresponds to a liquid feeding end of threeway 4 or goes out liquid
End；Intercommunication between each end of threeway 4 pointed by each instruction unit 45；Instruction unit 45 is equipped with arrow；
State shown in Fig. 2, two liquid feeding ends 42,43 of threeway 4 are connected with outlet end 44, i.e., tool is logical there are two infusion
Road；
Adjuster 41 in Fig. 2 is turned over into 180 degree counterclockwise, as shown in figure 3, then the first liquid feeding end 42 connects with outlet end 44
Logical, the second liquid feeding end 43 and outlet end 44 are obstructed, and there are one infusion accesses for threeway 4；Another infusion path blockade；If it needs at this time
Washing pipe is wanted, then can effectively prevent pouring blood back another liquid feeding end of threeway 4（Second liquid feeding end）；
If patient needs two-way fluid infusion, each instruction unit 45 of adjuster 41 is all directed to each end of threeway 4（Two into
Liquid end 42,43 and outlet end 44）, when needing washing pipe, then the path blockade that will infuse all the way.
