Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of novel hemodialysis puncture needle.
Background technology
At present, during domestic hemodialysis, generally use draw point or remaining needle.Fixed limb is needed after using puncture of steel needles, puncture limbs are not allowed to have any activity, otherwise very easily puncture blood vessel, especially the patient of those unconsciousness, or Aged Patients, once puncture blood vessel will cause puncture place ecchymosis, injured blood vessel, increase difficulty when patient suffering and puncture next time.When using remaining needle, need after piercing its tail end to be connected with haemodialysis control unit, owing to lacking corresponding blocking vessel, mostly use mosquito forceps to carry out substitute, blocking-up very easily occurs improper, cause blood samples of patients to run off, increase conflict between doctors and patients.Therefore, a kind of Novel puncture needle avoiding the problems referred to above of design is badly in need of.
Summary of the invention
The purpose of this utility model is, in current hemodialysis, the problem that draw point punctures blood vessel easily occurs, a kind of novel hemodialysis puncture needle is provided, draw point effectively can be avoided to puncture blood vessel and to cause damage, or cause the problems such as loss of blood because blocking improper, improve medical and nursing quality, reduce conflict between doctors and patients.
The technical solution of the utility model is:
A kind of novel hemodialysis puncture needle, comprise draw point and soft pin, described soft pin is made up of flexible plastic, and its bore is suitable with draw point, and there is multiple aperture its front end, and its rear end is connected with connection tube, and the total length of described soft pin and connection tube is less than the length of described draw point; Being inserted in described connection tube and soft pin of described draw point activity, and draw point head can expose from soft pin front end; Described connection tube is provided with the arm of oblique connection, and is provided with the plugging block that blood can be stoped to flow out between the tail end of this connection tube and described arm junction; The end of described arm connects the extension tube that can be connected with dialysis blood vessel.
Further, described draw point tail end is provided with pin handle, and this pin is the tail end that can be screwed in connection tube.
Further, described plugging block is made up of gum elastic.
Further, the end of described extension tube is provided with the sealing cap spun with it, is provided with pipe clamp in the middle part of it.
Further, described sealing cap can spin and seal connection tube tail end.
Further, the movable trocar sheath being sleeved on soft pin outside is also comprised.
The beneficial effects of the utility model:
This utility model is reasonable in design, easy to use, not only can avoid puncturing blood vessel, increases patient and to puncture the movable amplitude of limbs, and, medical care is operated more in order convenient, increase work efficiency, promote medical care quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-trocar sheath, the soft pin of 2-; 3-connection tube; 4-plugging block; 5-arm; 6-extension tube; 7-pipe clamp; 8-sealing cap; 9-draw point; 10-pin handle.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in Figure 1.
A kind of novel hemodialysis puncture needle, comprises draw point 9 and soft pin 2.Described draw point 9 length is about 10cm, hollow, and is provided with pin 10 at tail end, and pin is provided with connecting thread 10.Described soft pin 2 is made up of flexible plastic, flexible, and there is multiple aperture front end, can increase blood flow.The bore of this soft pin 2 is suitable with draw point 9, can be sleeved on closely on draw point 9.The rear end of this soft pin 2 is connected with connection tube 3, and both total lengths are less than the length of described draw point 9.Being inserted in described connection tube and soft pin of described draw point 9 activity, and when draw point 9 inserts completely, its head can expose about 5mm from soft pin 2 front end.The diameter of described connection tube 3 slightly larger than soft pin 2, and in the junction with soft pin 2 conically.The afterbody of described connection tube 3 is provided with the arm 5 of oblique connection, and its angle is about 150 ~ 160 °.The plugging block 4 that blood can be stoped to flow out is provided with between the tail end of this connection tube 3 and described arm 2 junction.This plugging block 4 is made up of gum elastic, can be pierced through by draw point 9 and pass through, and after draw point 9 is extracted, automatically can close, and stops blood to flow out.The tail end of described connection tube 3 is provided with connecting thread, can with pin spinning mutually.The end of described arm 5 is connected with extension tube 6, and the end of extension tube 6 can be connected with dialysis blood vessel.The end of this extension tube 6 is provided with the sealing cap 8 spun with it, and extension tube 6 can be closed before being connected with dialysis blood vessel, anti-Hemostatic Oral Liquid flows out.Meanwhile, the bore of this sealing cap 8 is identical with the bore of connection tube 3 tail end, and can, after draw point 9 is extracted, be screwed on the tail end of connection tube 3, connection tube 3 described in further shutoff, guarantees that blood does not flow out.The middle part of described extension tube 6 is provided with pipe clamp 7, can turn off or open extension tube 6, is convenient to it and the attended operation of blood vessel of dialysing.Further, described soft pin 2 outside is also provided with the trocar sheath 1 of movable suit, and its shape and bore all adapt with soft pin and connection tube 3, can be socketed on soft pin 2, and the opening of this trocar sheath 1 is clamped on connection tube 3, prevent draw point 9 and soft pin 2 from being polluted.
During use, the pipe clamp in extension tube is turned off, take off trocar sheath puncture.Puncture successfully, draw point is extracted and appropriate fixing soft pin, then, take off sealing cap side by side after net air, extension tube is connected with dialysis blood vessel, and opens pipe clamp, start dialysis.Finally, sealing cap can be tightened on the tail end of connection tube, strengthen plugging effect.
This utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
