Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of transfusion injection needle head that prevents once more injured blood vessel.
Background technology
At present; The vein garter injection needle that hospital uses mostly is disposable simple and easy syringe needle, though cheap, easy to use; But the shortcoming of a maximum penetrates behind the blood vessel syringe needle exactly and is easy to once more piercing blood vessel and makes institute's transfusion inject muscle, or swelling plays bag or pain is blue.At this moment, can only pull out syringe needle gravity treatment blood vessel pricks again and drips.And be to make the syringe needle piercing blood vessel no longer once more that penetrates blood vessel, patient just must carefully remain a relatively-stationary transfusion attitude for a long time, and the spy pulls the devil by the tail.Again prick to drip for the adult that blood vessel is prone to look for, what not to have behind the piercing blood vessel yet, but, just seem very painful for adiposis patient and infant that the blood vessel difficulty is looked for.Even to this day, also do not see have any garter injection needle of piercing blood vessel that can prevent once more to come out.
The utility model content
The purpose of this utility model is exactly the defective that exists to prior art, and a kind of transfusion injection needle head that prevents once more injured blood vessel is provided.
Its technical scheme is: comprise the needle tubing and the vascular sheath that have tube for transfusion, locating clamp plate and inclined blade needle point.Vascular sheath is sleeved on the needle tubing, and the one of which end is provided with sealing-plug, and sealing portion beyond the Great Wall is provided with the sheath clamp.
Wherein, said vascular sheath is served as reasons and is had that flexible nonmetallic materials are made, its front end is the tubular body of scalene cone structure.Said sealing-plug is the rubber-like rubber ring.
This utility model has advantage simple in structure, easy to use, with low cost compared with prior art.Be a kind of garter injection needle that can effectively prevent once more piercing blood vessel, have bright market prospects, substitute the desirable regeneration product of present widely used simple disposable garter injection needle beyond doubt.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
The specific embodiment
With reference to Fig. 1, a kind of transfusion injection needle head that prevents once more injured blood vessel comprises the needle tubing 1 and the vascular sheath 2 that have tube for transfusion 6, locating clamp plate 5 and inclined blade needle point.Vascular sheath 2 is sleeved on the needle tubing 1, and the one of which end is provided with sealing-plug 3, and sealing plug 3 outsides are provided with sheath clamp 4.Wherein, said vascular sheath 2 is served as reasons and is had that flexible nonmetallic materials are made, its front end is the tubular body of scalene cone structure.Said sealing-plug 3 is the rubber-like rubber ring.
During use, the inclined blade needle point through needle tubing 1 front end together inserts venous patient with needle tubing 1 and the vascular sheath 2 that is sleeved on the needle tubing 1, and is at this moment that sheath clamp 4 is fixing, holds locating clamp plate 5 pulling needle tubings 1, and vascular sheath 2 gets final product to make needle tubing 1 needle point shrink back into.
