Description

Automatic acupuncture and moxibustion injector

This utility model belongs to the acupuncture instrument.

Acupuncture therapy is one of the most valuable culture rarity of our Chinese nation.This ancient perverse technology of pin has its unique strong point, has won fame both at home and abroad already.But, also find to also have the some shortcomings part along with development of human society.For example, up to this point, its basic operation also almost rests on the situation of doctor's " hand-held needle body inserting needle ".Hand-held needle body inserting needle not only pollutes needle body easily, and causes the needle body bending damage easily.The patient has the feared state of mind to " bright pin " at large in addition, and this has more increased the weight of the sensation of patient's pain when inserting needle.This problem is that in all age each big family that cures discusses treatise specially and fails the effectively problem of solution.

The purpose of this utility model is to provide a kind of automatic acupuncture syringe, and it can penetrate into pin quickly and accurately cortex and distinguish bitterly and do not have pain or slight moment pain is only arranged, to solve the above-mentioned problems in the prior art.

This utility model looks and resembles a ball pen wherein have needle-clamping spring that acupuncture needle is clamped, and promotes to hit son by spring acupuncture needle is injected subcutaneous 3～4 millimeters of acupuncture point, and by back-moving spring it is returned to state to be penetrated.This utility model has realized that basically there is " painless pin is perverse " difficult problem for many years in the acupuncture technique aspect.Can stop hand-held needle body inserting needle needle body bending that is caused and the phenomenon of polluting needle body.Simultaneously, because patient can not see pin (blind stitch), significantly reduced and feared pin psychology.This instrument proves through development and clinical use for many years, can promote the use of fully.

Accompanying drawing 1 is this utility model overall structure cross-sectional schematic, wherein hits son and does not partly do to analyse and observe.

Accompanying drawing 2,3,4 is this utility model user mode partial schematic sectional view.

1 ejection chamber in the accompanying drawing, 2 outer pin chambeies, 3 interior pin chambeies, 4 locking nuts, 5 nylon sheath wires, 6 launch the spring cover, 7 hit son, and 8 hit the son pin, 9 wedge-shaped slots, and 10 launch spring, 11 back-moving springs, 12 buttons and envelope, 13 needle-clamping springs, 14 alignment pins, 15 locating slots, 16 acupuncture needles, 17L shape groove.

In the embodiment shown in the figures, ejection chamber 1 and outer pin chamber 2 are with screw threads for fastening together, outer pin chamber 2 is the pipe that left end opening right-hand member sealing the center has a circular hole, in but the interior pin chamber 3 of pull is arranged, with the acupuncture needle 16 that adapts to different length, controlling the degree of depth that acupuncture needle 16 is injected Intradermal simultaneously.Acupuncture needle 16 can pass above-mentioned circular hole.Locking nut 4 is screwed in the left end in outer pin chamber 2 with the gas thread form, can be locked in interior pin chamber 3 on the desired position.Locking nut 4 outer walls are with nylon sheath wire 5, are beneficial to control and outward appearance appearance.Ejection chamber 1 is the pipe of a both ends open.Launch spring cover 6 and be the pipe of right-end openings, it can extend in the ejection chamber 1, and the latter's internal diameter matches with the former external diameter.Launch that left ends hit son 7 in the spring cover 6, the latter's cross section is a convex shape, hits son pin 8 and crosses and hit son 7, and its two ends are stretched out the part of hitting son 7 and inserted L shaped groove 17 on ejection chamber 1 side wall surface respectively, and this L shaped groove 17 has 2, and their centrosymmetry ground is distributing.2 wedge-shaped slots 9 are symmetrically distributing on the side wall surface that launches spring cover 6.Above-mentioned the stretching out partly of son pin 8 two ends of hitting also inserted respectively in this wedge-shaped slot 9.Under the effect of launching spring 10 and wedge-shaped slot 9 left end inclined planes, hit son pin 8 " locks " on the vertical slot top of L shaped groove 17 right-hand members (hit son 7 among Fig. 1 and promptly be in this kind state).The lower limits of finding out L shaped groove 17 and wedge-shaped slot 9 easily is on a line, and the two ends of hitting son pin 8 are locked in L shaped groove 17 and the wedge-shaped slot 9 all the time.Launch spring and overlap the outer right part of 6 walls back-moving spring 11 is arranged, can make by its elastic force and launch spring cover 6 after launching and return on the position to be launched together with hitting son 7.Button and envelope 12 are enclosed within the outside of ejection chamber 1 and back-moving spring 11.Fixing two L shaped needle-clamping springs 13 in the ejection chamber 1 symmetrically, in order to clamping acupuncture needle 16.Also fixing alignment pin 14 on ejection chamber 1 inwall, the latter's end is inserted in launches on the spring cover 6 in the strip axial location groove 15, guaranteeing that launching spring cover 6 can only make axially reciprocating in ejection chamber 1, and can not produce relative rotation.

During use, hand syringes press...withes one's finger and presses button and envelope 12 ends, launches spring cover 6 and moves right, and further stretches in ejection chamber 1.When launching spring cover 6 and move to certain position (Fig. 2), clamping spring 13 makes acupuncture needle 16 be in the state that is not held just by the extruding of its left part and separate.Here illustrate in passing that also so action promptly touches the button earlier and envelope 12 when packing acupuncture needle 16 into, makes it move right certain distance, again from interior pin chamber 3 left port with the sterilization tweezers acupuncture needle 16 of packing into, loose one's grip then, acupuncture needle 16 promptly is held spring 13 and clamps.Launch that to hit son 7 when spring cover 6 begins to move right motionless, because hit the top that the two ends of son pin 8 still are blocked in L shaped groove 17 vertical slots.At this moment, launch spring 10 and return spring 11 all is compressed.When launching spring cover 6 and continuing to move right the certain distance (see figure 3), the inclination wedge surface of wedge-shaped slot 9 right-hand members on its sidewall begins contact and hits son pin 8, and forces the latter to move downward along the vertical slot of L shaped groove.At this moment, in fact hitting son pin 8 is rotating together with hitting son 7.When the two ends of hitting son pin 8 turn to translot partly the time by the vertical slot of L shaped groove, launch spring 10 and back-moving spring 11 all is compressed into the tightest state.In a single day the two ends of hitting son pin 8 turn to the translot place of L shaped groove 17, and because of no longer being stopped, hit sub 7 springs 10 that launch that promptly discharged rapidly and promote, the afterbody of bump acupuncture needle 16, and with its ejaculation.Release button and envelope 12, back-moving spring 11 restores to the original state, and just sends back on the position to be launched together with hitting son 7 launching spring cover 6.

This utility model can be with manufacturings such as rustless steel or rigid plastics.As use plastics, ejection chamber 1 also can be threaded with outer pin chamber 2, and both injection mouldings are become one.Ejection chamber 1 and launch spring cover 6 and also can change into squarely simultaneously removes alignment pin 14 and locating slot 15 this moment.Right-hand member of the present utility model also can be provided with a disinfectant cap, and during use, a disinfectant cap is once just changed in every injection.

This utility model is made easily, and cost is low, and is light durable, and operation easily, its appearance will make acupuncture therapy obtain to popularize more widely and improve.
