Abstract
The utility model discloses a solid syringe needle for artery and vein puncture, abdominal cavity and thoracic cavity puncture, and scalp blood vessel puncture, etc. By utilizing the mechanics principle that a solid wedge-shaped face changes the cutting force to the thrust force, the utility model changes a hollow knife-edge needle head of the existing needle head to a sharp solid needle point, and the shape of the sharp solid needle piont likes a stitch needle point. The back end of the needle head adopts a needle head body which is a hollow cylindrical shape, and the side wall of the needle head body is provided with at least two injecting holes in spiral distribution, and the inner orifice of the needle head is cast on the lower end of a handle of the needle head. By using the utility model to inject, the solid syringe needle can avoid defects that when a doctor uses the hollow knife-edge needle point type needle head to inject, human tissues can be cut and this can cause ache; such hollow knife-edge needle point is easy to generate needle hole blocking and causes the physic liquor to outward leak.
Description
This utility model relates to a kind of improved syringe needle, particularly a kind of solid sharp syringe needle.
Now be used for the clinical porous of using as injection for curing such as muscle, artery and vein puncture, splanchnocoel puncture, scalp vein puncture or the needle point of single hole syringe needle, it all is hollow tooth shape needle tip, borrow during injection the tissue perpendicular cuts, make needle head body enter human body, direct treatment of traumatic pain appears in the injection, scleroma appears in the injection back, because of the hollow Chang Yi of needle point is stopped up by cutting tissue fragment, difficult and then the outflow of medicinal liquid when causing injection, the Drug therapy amount reduces thereupon, thereby has influenced therapeutic effect.Even cause the bland necrosis tuberosity because of cutting nerve, or infect and cause limbs disturbance.
Task of the present utility model just provides a kind of patient's no pain, does not have scleroma, and is little to injury of human, and do not reveal the syringe needle of liquid.
Task of the present utility model is finished as follows: the front end at solid sharp syringe needle is the pointed solid needle point of the solid sewing needle of a metal, because when injection and people's contact level are little, arrange tissue with the effect of wedge surface dividing potential drop, the wound of having avoided cutting to cause, behind the inserting needle again by the sidewall injection orifice medicinal liquid that between tissue, distributes, reached the injection site and do not produced the aseptic necrosis scleroma, the injection for curing effect of no pain.
Accompanying drawing is a cutaway view of the present utility model.
Below in conjunction with accompanying drawing this utility model is described in further detail:
At the front end of solid sharp syringe needle is one to be the pointed solid needle point [ 6 ] of sharp suture needle, be that needle head body [ 4 ] needle head body [ 4 ] that medicinal liquid passes through be that empty garden cylindrical inner wall is smooth thereafter, the injection orifice more than 2 [ 2 that sidewall has spiral type to distribute, 5,7 ] be interlinked to the outside with needle head body [ 4 ], the internal orifice of needle head body [ 4 ] is cast in the lower end of pinhead handle [ 1 ], pinhead handle [ 1 ] is that the handle of falling a taper abdomen [ 3 ] is arranged in T-shaped plastics of shell-like or metal needle handle [ 1 ] pinhead handle [ 1 ], the upper end is syringe needle collar extension [ 8 ], and the lower end is syringe needle internal orifice [ 9 ].During use, used needle tubing chewed from syringe needle collar extension [ 8 ] insert, the medicinal liquid that needle tubing is released promptly locates to enter needle head body [ 4 ] at syringe needle internal orifice [ 9 ], and during medicinal liquid process needle head body [ 4 ], the injection orifice [ 2,5,7 ] that enters needle head body [ 4 ] sidewall is injected in human body by these injection orifices.When dashing the various medicament of suction, the solid spine of syringe needle is gone into medicine bottle, medicinal liquid can suck needle tubing by sidewall injection orifice [ 2,5,7 ], absorbs in the time of also medicine bottle can being inverted.
Solid sharp syringe needle is compared with existing hollow tooth shape point syringe needle, because of solid point is that sharp keen suture needle is pointed, during use, has easy inserting needle, does not have scleroma, no pain, does not reveal the advantage of liquid, can be widely used in clinical injection.
Claims (1)
1, the syringe needle used of a kind of puncture for treating, its front end has a needle point, is thereafter the needle head body that medicinal liquid passes through, and the needle head body internal orifice is cast in the lower end of pinhead handle, and the needle point that it is characterized in that syringe needle is the sharp solid needle point [6] of a shape such as suture needle point.
