Description

A kind of subcutaneous medicament filling gun

Technical field:

This utility model relates to a kind of medicament injection apparatus.

Background technology:

Having now adopts medicine that human body is comprised speckle more effectively, the U.S. molding process of wrinkle removing is realized by subcutaneous injection genomic medicine (as the low molecular peptide class), why adopt the subcutaneous injection mode, be in order to guarantee the absorption of skin to medicine, the main points that adopt this kind mode are to make the subcutaneous of each position of that part of skin (as facial skin) of the human body that required U.S.A moulds can both obtain uniform medicine, so just that part of skin of the human body that need mould in needs U.S.A reaches up to ten thousand times acupunctures, adopt general syringe with manually being impossible the realization, moreover, the degree of depth of acupuncture can only arrive does not have neural place below the skin, otherwise human body will be difficult to because prickling sensation is arranged accept.

Summary of the invention:

Goal of the invention of the present utility model be to provide carry out repeatedly acupuncture trace drug injection in a kind of short time automatically, depth of needling is easy to adjust and each stable subcutaneous medicament filling gun of depth of needling.

This utility model is to realize like this, by the rifle body, be arranged on the micro-injection mechanism on the rifle body, acupuncture mechanism, depth of needling governor motion and electric control switch, controller for electric consumption constitutes, micro-injection mechanism is by the syringe that is arranged on the rifle body, be arranged on the injector push-rod back and be threaded in briquetting on the screw mandrel, drive the power set formation that screw mandrel rotates, briquetting is positioned at the guide groove of rifle body, acupuncture mechanism is by injection needle, with the fixed clip of injection needle, the altofrequency that drives the set a distance motion of clip front and back moves forward and backward device back and forth and constitutes, the depth of needling governor motion is by having the pressing plate that injection needle passes mouth, drive laterally move and the bar that be connected with wire rod thread of pressing plate, being positioned at the intravital and runner that be connected with screw mandrel on the bar of rifle constitutes, be connected by flexible pipe between injection needle and injector to inject mouth, the shake-up signal of telecommunication output of gauge tap links to each other with the signal of telecommunication input of controller for electric consumption, and controller for electric consumption control drives power set and the electromagnetism adhesive device action that screw mandrel rotates.Here, altofrequency move forward and backward back and forth device by be fixed on the intravital support of rifle, move forward and backward the connecting rod that is arranged on the support, be arranged on the spring between connecting rod and support, the electromagnetism adhesive device that is arranged between connecting rod and support constitutes, link end and clip are fixed together.During work, the syringe of filling medicinal liquid is fixed on the rifle body, make briquetting be pressed in the push rod back of syringe, the bar that has screw mandrel by rotating wheel moves forward and backward, when making injection needle be advanced to foremost, the distance that injection needle protrudes from pressing plate is equal to the distance that injection needle reeve skin sets below, then by pressing gauge tap, making controller for electric consumption control altofrequency move forward and backward device back and forth drives clip and does together with injection needle that altofrequency moves forward and backward or single moves, simultaneously, power set drive screw mandrel and rotate, and briquetting pushing syringe push rod is moved, and the action that cooperates each acupuncture is toward the subcutaneous injection trace drug.

This utility model compared with the prior art, owing to adopted micro-injection mechanism, acupuncture mechanism, depth of needling governor motion and micro-injection mechanism, acupuncture mechanism organically moved by controller for electric consumption, therefore, have carry out repeatedly acupuncture trace drug injection in the short time automatically, depth of needling is easy to adjust and each stable advantage of depth of needling.
