The Z D comprises a sliding cap, a fixing cap, a power device, a locking device, a releaser and a connecting sleeve,wherein, the sliding sleeve has a piston at one end and a lug boss handle at the other end; one end of the piston is extended into an annular cavum of the fixed sleeve and then slides freely along the axial direction; the power device is a spring; the needle head of the injector is just hided inside an almuce hood under the state of locking. When in use, first make preparations, then press lightly the releaser by aiming at position, thus inserting the needle in shape. The utility model, due to the action principle of orifice, is able to insert the needle quickly without wallop; the almuce hood of the fixed sleeve is capable of ensuring the depth of needle inserting for one time effectively; therefore, the utility model is suitable for patients needing for self injection, which is like a nurse for your daily life.

Description

The automatic acupuncture treatment device of syringe

Technical field

This utility model relates to a kind of automatic acupuncture treatment device of syringe.

Background technology

Syringe is that liquid preparation is transported to the intravital a kind of utensil of flesh.Generally speaking, in hospital, all be to have an injection to patient with syringe by the nurse, a part of diabetic in the life but needs to carry out for a long time the self-injection of insulin.At present, though can buy various insulin syringes at pharmacy, for example have: the Americanized BD insulin syringe (universal) of the precious insulin syringe in the landrover east of a, b, promise that c Denmark makes and an insulin syringe etc., though these syringe syringe needles are very thin, though it is also convenient to use, they but do not have the function of automatic acupuncture treatment.Diabetic is in the self-injection insulin, a kind of feared state of mind is held in acupuncture treatment, so it is special nervous that emotion becomes, be easy to take place that multiple phenomenon not in place: a acupuncture treatment speed is slow, the b position is inaccurate, depth of needle of c not enough, the d syringe needle carefully curves easily or fracture etc., so increase psychological obstacle all the more, think that self-injection is a painful thing.

The utility model content

The technical problems to be solved in the utility model provides a kind of automatic acupuncture treatment device of syringe, automatically the acupuncture treatment device is called for short ZD, it can mate various syringes and be combined into an integral body with it, for example: the precious insulin syringe in ZD east, ZD-BD insulin syringe, ZD promise and an insulin syringe, the universal syringe of ZD etc.

For solving the problems of the technologies described above, conception of the present utility model is the automatic acupuncture treatment device that adopts a kind of like this syringe, and it comprises: slip cap, fixed cover, power set, locking device, release, adapter sleeve; One end of slip cap is a piston, and the other end is the boss handle; Fixed cover guard shield, fuse with overcoat and interior cover, damping hole is communicated with toroidal cavity; Piston one end of slip cap extend into the toroidal cavity of fixed cover, and can be free to slide vertically; Power set can provide kinetic energy for slip cap; Locking device is the mechanism that slip cap is locked in the pull-out location, and under lock-out state, the syringe needle of syringe is just in time in the indentation guard shield; Described release, it can unlock device to the qualification of power set, and makes power set return to original state; Adopt between slip cap and the adapter sleeve and flexibly connect.

The centrage of slip cap, fixed cover and adapter sleeve, with the centrage of syringe on same straight line.

With the fit clearance of overcoat and interior cover about 0.03～0.06 millimeter respectively in the piston of slip cap to guarantee the damping action of damping hole to piston, reaches the buffering purpose.

The pressure button cover of release is fixed on the button piece on the outer wall of overcoat; There is the oblong aperture that is suitable for the very heavy use of locking device the corresponding position of overcoat.

Power set can be cylindroid helical-coil compression springs, and the two ends of spring withstand on the end face of piston and baffle ring respectively; Baffle ring is fixed on the inwall of overcoat.

Power set can also be cylindroid helical-coil extension springs, and the two ends of spring are hung on hook A and the hook B; Hook A is fixed on the circular tube external wall of slip cap, and hook B is fixed on the inwall of overcoat.

Locking device can be to be made of very heavy, little spring, axle and bearing; Bearing is fixed on the circular tube external wall of slip cap; During lock-out state, very heavy the button piece is ejected, and make its outstanding pressure button cover.

Locking device can also be that a stock formula that directly links to each other with the circular tube external wall of slip cap is very heavy; During lock-out state, very heavy the button piece is ejected, and make its outstanding pressure button cover.

Automatic acupuncture treatment device of the present utility model, it can organically form a whole with various syringes, makes syringe have the function of automatic acupuncture treatment.Carry out various preparations during use earlier, aim at select location then and click release more gently, moment has just been finished acupuncture treatment; Because the action principle of damping hole makes inserting needle speed but not have impulsive force soon; The guard shield of described fixed cover can guarantee the degree of depth of an inserting needle again effectively, so phenomenon not in place just can not take place naturally.The patient of self-injection has not had frightened or nervous sensation, and misery has also just disappeared naturally at leisure.The ZD syringe is applicable to the patient who needs self-injection.The ZD syringe is the Mininurse during you live.

Description of drawings
