Description

Disposable one hand send tubular type venous indwelling syringe needle

Technical field

The present invention a kind ofly can simplify the nursing technique operating process, improves success rate of venous puncture, alleviates the medical material of less patient suffering.

Background technology:

The present syringe needle (like Figure of description 1, accompanying drawing 2) of the used disposable vein remaining needle of health service unit, at present clinically, use this venous indwelling syringe needle that the program that vascular puncture adopts is had two kinds:

1. the puncture program that generally adopts, when puncture, the right hand is responsible for puncture, and left hand is responsible for the skin and the blood vessel of exceptionally straight site of puncture; When seeing blood back, the right hand is held the indwelling syringe needle and is moved ahead about 2 millimeters, and it is fixed that this moment, the right hand was held the indwelling syringe needle; Owing to realize the singlehanded structure that send pipe on the venous indwelling syringe needle of using clinically at present, the right hand can not be directly let the acupuncture needle remain at a certain point that the headgear pipe is directly sent into blood vessel with vein, must left hand be drawn back; Because left hand is responsible in blood vessel, sending the indwelling needle sleeve, in the process of drawing back leftward, causes exceptionally straight skin of left hand and blood vessel loose; The generation skin heart is divided a word with a hyphen at the end of a line, and is prone to cause remaining needle to deviate from blood vessel, causes puncture failure.So the shortcoming that the venous indwelling syringe needle that uses at present exists on this operation sequence is: operate more loaded down with trivial detailsly, action stability is poor, and puncture success rate is low.

2. in particular cases puncture program, when puncture, the right hand is responsible for puncture; Left hand is responsible for the skin and the blood vessel of exceptionally straight site of puncture, after seeing blood back, by the right hand draw point and sleeve pipe is directly sent into blood vessel, withdraws from nook closing member again; Though this puncture procedure can realize that one hand send pipe, because the puncture needle of used disposable indwelling syringe needle is long and softer, yielding at present; Be difficult to control, feel is poor, stabs blood vessel sending simultaneously to blood vessel very easily to pierce through in puncture needle and the sleeve pipe process; Sepage takes place, thereby causes puncture failure.So the shortcoming that the venous indwelling syringe needle that uses at present exists on this operation sequence is: be prone to piercing blood vessel, puncture success rate is low.

If puncture failure needs to change remaining needle and punctures once more, cause the waste of medical material, increase nursing staff's workload, increase less patient suffering.
