Abstract
The utility model discloses an automatic injection machine, which comprises a frame, a motor fixed on the frame, and a primary worm screw, a secondary worm screw and a screw which are erected on the frame. The rotating shaft of the motor is fixedly connected with the primary worm screw; the primary worm screw is meshed with a primary worm wheel arranged above the primary worm screw; the primary worm wheel is coaxially and fixedly connected with the secondary worm screw; the secondary worm screw is meshed with a secondary worm wheel arranged below the secondary worm screw; and the secondary worm wheel is connected with the screw through thread. The automatic injection machine has the characteristics of simple structure, convenient operation, time-saving property and labor-saving property, and effectively improves the operability in drug injection.
Description
Technical field
This utility model relates to a kind of device that patient is injected automatically, belongs to field of medical.
Background technology
When the nurse uses syringe to patient injection, need manually carry out, owing to length difference inject time, the needs that have are more than several hours, the manual injection just quite bothers in this case, waste time and energy, and, cause patient's pain and other untoward reaction easily because the propulsive speed of injection is inhomogeneous.
Summary of the invention
For solving the problem of above existence, this utility model provides a kind of automatic injector, and its technical scheme of taking is:
The one-level worm screw, second-stage worm and the screw rod that comprise frame, be fixed on the motor on the frame and be erected at, the rotating shaft of motor is fixedlyed connected with the one-level worm screw, the first-stage worm gear that one-level worm engaging is provided thereon, first-stage worm gear is fixedlyed connected with second-stage worm is coaxial, the second-stage worm gear below it is located in the second-stage worm engagement, and second-stage worm gear is connected with screw flight.
Rotate by driven by motor worm and gear combination, the worm and gear combination drives screw rod and travels forward, thereby the slow uniform motion of the piston rod on the pushing syringe reaches the purpose of injection.The utlity model has simple in structure, easy to operate, time saving and energy saving characteristics, effectively improved the operability of medicine injection.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further:
As shown in the figure,, motor 2 is fixed on the sidewall of frame 8, one-level worm screw 3, second-stage worm 5 and screw rod 7 are erected at the diverse location on the frame 8 respectively, the rotating shaft of motor 2 is fixedlyed connected with one-level worm screw 3, the first-stage worm gear 4 that 3 engagements of one-level worm screw are provided thereon, first-stage worm gear 4 and second-stage worm 5 coaxial fixedlying connected, the second-stage worm gear 6 below it is located in second-stage worm 5 engagements, second-stage worm gear 6 center hole inwalls have screw thread, and screw rod 7 passes circular hole and is threaded with second-stage worm gear 6.
When using this utility model, syringe 1 is filled medicinal liquid is fixed on the frame 8, the piston rod on the syringe 1 is near the front end of screw rod 7.Give motor 2 energisings, rotate 3 rotations of drive one-level worm screw by motor 2, one-level worm screw 3 drives first-stage worm gear 4 and rotates, and then by first-stage worm gear 4 transmissions, drive second-stage worm 5 rotations, and then drive second-stage worm gear 6 rotations, finally drive screw rod 7 and travel forward, thereby the slow uniform motion of the piston rod on the pushing syringe 1 reaches the purpose of injection.
