Abstract
This utility model provides venipuncture needle under a kind of Novel clavicle, and comprise needle tubing, needle stand and side, needle tubing is fixed on needle stand, needle tubing has beveled point foremost, the inclined-plane of this needle point and side are in same direction, and side is the tube chamber with unidirectional valve, are connected to the right side of needle stand.This utility model needle tubing front end has certain flexibility, shoulder check can be avoided, cross the laggard dial of clavicle out of shape upward, can avoid lungs and subclavian artery, enter subclavian vein more accurately, this venipuncture needle is specifically designed to subclavian vein puncture, easy to use, increase work efficiency and puncture success rate, decrease complication and occur, safe and reliable.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of subclavian vein puncture pin.
Background technology
At present, subclavian vein catheterization art is increasingly extensive in clinical practice, especially acts on particularly important in critical patient rescues.Use linear type puncture needle clinically at present, to upwarp because of clavicle and subclavian vein is arciform out of shape, need before puncture to get at shoulder underlay pillow head vertical position afterwards of lying on the back, reduce with tractive shoulder and puncture needle is stopped, and the staight needle that punctures is easy to the subclavian artery and the lungs that enter respective planes, and pneumothorax, arterial hemorrhage, even threat to life occur.Especially injure in critical patient rescue multiple, be satisfied with pricking body position because state of an illness restriction cannot obtain.Mortality and complication rate usually perplex the development of this technology.How to improve puncture success rate and avoid the requirement of complication day by day urgent.
Summary of the invention
The purpose of this utility model is to provide venipuncture needle under a kind of Novel clavicle, this needle tubing front end has certain flexibility, can avoid shoulder check, crosses clavicle laggard dial forward upward out of shape, lungs and subclavian artery can be avoided, enter subclavian vein more accurately; This venipuncture needle is specifically designed to subclavian vein puncture, easy to use, increases work efficiency and puncture success rate, decreases complication and occurs, safe and reliable.
The technical solution of the utility model is: venipuncture needle under a kind of Novel clavicle, comprise needle tubing, needle stand and side, needle tubing is in succession on needle stand, needle tubing front end has certain flexibility, and needle tubing has beveled point foremost, and the inclined-plane of this needle point and side are in same direction, clear and definite directivity can be provided for operator, side is the tube chamber with unidirectional valve, is connected to the right side of needle stand, is applicable to puncture successfully insert seal wire at this side.
Wherein the flexibility of needle tubing front end is 30 ~ 35 °.
The bending point of needle tubing front end is taken from apart from needle point 3 ~ 4 centimeters.
Advantage of the present utility model: needle tubing front end has certain flexibility, meets human body physiological characteristics, does not limit by pricking body position, and the scope of application is wider; Unidirectional valve avoids air embolism and blood to flow out; Pinpoint inclined plane is consistent with side direction, points to clear and definite when inserting seal wire; Simple and compact for structure, easy to use, safe and reliable.

Fig. 4 is the right side view of the another kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
As depicted in figs. 1 and 2, a kind of subclavian vein puncture pin, comprises needle tubing 2, needle stand 1 and side 4, needle tubing 2 is in succession on needle stand 1, needle tubing has beveled point 3 foremost, and the inclined-plane of this needle point 3 and side 4, in same direction, can provide clear and definite directivity for operator; Needle tubing front end has the flexibility of 30 ~ 35 °, and the bending point of needle tubing front end is taken from apart from needle point 3 ~ 4 centimeters.Side 4, for having the tube chamber of unidirectional valve 5, is connected to the right side of needle stand 1, is applicable to puncture successfully insert seal wire at this end.
Subclavian vein arises from the lateral border of the first rib, before be the medial border of clavicle, clavicle mid point slightly between clavicle and the first rib slightly upwards inwardly arcuately and slightly toward interior lower out of shape.
Needle stand 1 is pressed to horizontal level by this puncture needle after crossing clavicle, the flexibility of needle tubing front end is 35 °, and bending point is taken from apart from needle point 3.5cm place, and now the front end of puncture needle upwards, subclavian artery and apex pulmonis can be avoided, and subclavian vein can be entered smoothly in anticipation plane.The inclined-plane of needle tip 3 and side 4, in the same side, can provide guidance quality accurately when inserting seal wire.Side 4 has unidirectional valve 5, air can be avoided to enter in conduit, thus when making intubate, the danger of air embolism not easily occurs.
As shown in Figure 3 and Figure 4, side 4 and unidirectional valve 5 can also remove by this utility model, can adopt the syringe with hollow during Clinical practice, dispose into puncture seal wire by hollow, can reach the object of puncture subclavian vein equally.
