Abstract
The invention provides a painless trace anesthetic injector, which is characterized by comprising a step motor, an eccentric wheel, an injection needle, an agentia tube, a piston, a connecting shaft and a push rod, wherein the eccentric wheel is connected with the step motor, and driven to rotate by the step motor; the injection needle is used for injecting an anesthetic; the agentia tube and the injection needle are arranged side by side, and communicated with each other; the potion is arranged in the agentia tube; one end of the connecting shaft is connected with the injection needle, and the other end of the connecting shaft is connected with the piston; and the push rod is connected between the eccentric wheel and the connecting shaft, and converts a rotating force of the eccentric force into a downward thrust. According to the painless trace anesthetic injector disclosed by the invention, because the injection needle and the piston move simultaneously, when a syringe needle is inserted into the skin tissue, the piston supplies a moderate amount of trace anesthetic to the syringe needle, and because the whole needle inserting, injection and needle withdrawing process is completely finished under the driving of the eccentric wheel in the one revolution process of the eccentric wheel, the speeds of needle inserting and withdrawing are very fast, therefore, the purpose of painless injection can be achieved.
Description
Technical field
The present invention relates to a kind of painless micro-fix device, belong to medical instruments field.
Background technology
Dentistry and or the operation among a small circle of face, doctor often needs the anesthetis to the local organization such as gingiva or eyelid injection trace, to reach the effect of local anesthesia, but existing injection system usually still adopts the mode of doctor's hand syringes to carry out note and pushes away.The defect of this syringe is, because syringe needle is longer, can bring larger misery to patient.Meanwhile, because the area of local anesthesia is less, required anaesthesia dosage is also little, and traditional anesthetis is difficult to the object reaching dose injection.
Summary of the invention
The object of the present invention is to provide a kind of painless micro-fix device, to solve the problem.
Present invention employs following technical scheme:
A kind of painless micro-fix device, is characterized in that, comprising: motor; Eccentric, is connected with motor, rotates under the drive of motor; Entry needle, for injecting narcotic; Medicament cartridge, is arranged side by side with entry needle, and is connected; Piston, is arranged in medicament cartridge; Connecting axle, one end is connected with entry needle, and the other end is connected with piston; Push rod, is connected between eccentric and connecting axle, and the power of eccentric rotation is converted into downward thrust.
Further, painless micro-fix device of the present invention, can also have such feature: wherein, medicament cartridge is connected by flexible pipe with entry needle.
Further, painless micro-fix device of the present invention, can also have such feature: wherein, the position of medicament cartridge is relatively fixing.
Further, painless micro-fix device of the present invention, can also have such feature, also comprise: shell, medicament cartridge is fixed on the inwall of shell.
Further, painless micro-fix device of the present invention, can also have such feature: wherein, medicament cartridge place also has leve monitor.
Further, painless micro-fix device of the present invention, can also have such feature: wherein, and per injection motor rotates a circle.
The beneficial effect of the invention
According to painless micro-fix device of the present invention, because entry needle and piston move simultaneously, when syringe needle inserts skin histology, piston has supplied appropriate micro-anesthetis to syringe needle, due to the process of inserting needle whole under eccentric drive, injection, the withdraw of the needle, namely all complete in the process that eccentric rotates a circle, the speed of inserting needle and the withdraw of the needle is very fast, therefore, the object of painless injection can be reached.
Accompanying drawing explanation
Fig. 1 is the external structure schematic diagram of painless micro-fix device of the present invention;
Fig. 2 is the internal structure schematic diagram of painless micro-fix device of the present invention.
Detailed description of the invention
Below combine accompanying drawing and the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, painless micro-fix utensil has: motor (not shown); Eccentric 11, push rod 12, connecting axle 13, medicament cartridge 14, fixed bar 15, entry needle 16, flexible pipe 17, piston 18 and shell 20.
Eccentric 11 is connected with motor, rotates under the drive of motor.When carrying out the injection at a position, namely motor stops after being only with movable eccentric wheel to rotate one week.
Push rod 12 is connected on eccentric eccentric shaft, and eccentric rotatory force is become downward motive force.
Connecting axle 13, mid portion and push rod 12 are rotationally connected.The two ends of connecting axle 13 are connected with piston 18 with entry needle 16 respectively, drive entry needle 16 and piston 18 to move simultaneously.
Medicament cartridge 14, is arranged side by side with entry needle, and medicament cartridge 14 is fixed on shell 20 by fixed bar 15.Medicament cartridge is connected with entry needle 16 by flexible pipe 17, and when the piston is moving down, medicament is injected in entry needle 16 through flexible pipe 17 from medicament cartridge 14.Between medicament cartridge 14 and flexible pipe 17, also there is check valve, ensure that medicament is only from medicament cartridge 14 to entry needle 16 one-way flow.Medicament cartridge 14 also by another check valve be connected with medicament storage cylinder (in figure, not showing medicament storage cylinder) make after a shot, when piston 18 moves upward, from medicament storage cylinder to medicament cartridge 14 supplement medicament.
Entry needle 16, for injecting narcotic, stretches out from shell, under eccentric drive, do stretching motion.
Piston 18, is arranged in medicament cartridge 14, is pushed to by medicament in entry needle 16.
In addition, medicament cartridge place can also arrange leve monitor, sends warning when medicament is not enough.
Motor is set to, and a circle is only rotated in per injection, prevents excess injection.
Painless micro-fix device of the present invention, motor band movable eccentric wheel rotates and injects, and the speed flexible due to syringe needle is fast, therefore, it is possible to effectively alleviate the pain produced in injection process.
