- Japanese Patent Application Laid-Open No. Sho 63-216 16777 proposes a device that appears to provide a device with a relatively simple structure, a structure that requires considerable consideration in its design, and that is put to practical use. I can't imagine doing it.
- An object of the present invention is to provide a simple needle removing device having a structure capable of rotating a chuck device without requiring a rotary power transmission device. It is another object of the present invention to provide an injection needle removing device in which the operation of the chuck device is performed by linear movement of a solenoid.
- a housing including a cover having a circular opening for inserting a needle attached to a syringe and a support having a passage aligned with the circular opening, and a support for the housing.
- a chuck device having chuck claws for grasping the needle base of the injection needle from three directions, a device for opening and closing the chuck claws when the injection needle is inserted through the circular opening, and a housing rotatably.
- the device for rotating the housing with respect to the container includes: a motor with a reduction gear fixed in the housing; a spur gear fixed to an output shaft of the motor; And a ring gear provided, wherein the spur gear meshes with the ring gear of the container when the housing is coupled to the container.
- FIG. 1 is a schematic perspective view of a syringe needle removing device and a syringe according to the present invention.
- FIG. 2 is a top perspective view of a part of the injection needle removal device according to the present invention with the cover removed.
- FIG. 3 is a longitudinal sectional view of the device according to the present invention.
- FIG. 4 is a plan view of the present apparatus showing the chuck claws in an open state.
- FIG. 5 is a plan view similar to FIG. 4, showing the chuck claws in a closed state.
- an injection needle removal device 10 includes a cylindrical housing 11, a cover 12 screwed into the housing 11, and having a circular opening 13 in the center.
- Housing 11 and cover 13 are plastic
- the molded product is preferably
- the housing 11 has a reduced diameter portion 16 that fits into the circular opening 15 of the container 14 and a shoulder 18 that contacts the end face 17 of the container 14 that forms the circular opening 15.
- the housing 11 includes a hollow support 21 extending upward from the bottom wall 19 concentrically with the housing 11 and having a passage 20 in the center.
- the chuck device 22 is installed at the upper end of the hollow support 21 and the needle 25 is attached to the cartridge holder 24 of the syringe 23.
- each of the chuck jaws 26 is engaged with a notch 32 formed in the operation plate 28.
- the rear end bent portion 33 of the hook 26 is operatively connected to the support plate 28 by engaging the rear end bent portion 33.
- the chuck pawl 26 is held on the support plate 28 by fitting a retaining ring 35 into an annular groove 34 formed in the support bin 27.
- the movable disk 36 has, at its center, a circular opening 37 aligned with the hole 30 of the operating plate 28, and three small holes 38 around this central circular opening 37. By loosely passing the holes 38 through the support pins 27, the holes 38 can be vertically movably attached to the support pins 27.
- the movable disk 36 has an annular raised peripheral portion 39 formed around a central circular opening 37.
- the movable disc 36 has an arm 40 extending in a radially outward direction.
- the arm 40 is provided with an operating piece of a microswitch 42 provided on a circuit board 41 installed in a housing 11. Located on 4 3.
- Coil spring A ring 44 is provided around the support pin 27 between the movable disk 36 and the chuck jaw 26 to move the arm 40 so that the operating piece 43 of the microswitch 42 is not operated. 36 is constantly pushing upwards. When the movable disc 36 is pushed down against the action of the coil spring 44, the arm 40 of the movable disc 36 pushes the operating piece 43 to turn on the micro switch 42.
- the cover 13 has a force bar around a circular opening 1 3 ′ centered on a recess 45 engaging the top of three support pins 27 for mounting the cover 13 in place on the housing 11. It has on the lower surface of.
- the annular raised periphery 39 of the movable disk 36 is received in the circular opening 13 ′ of the cover 13 and is exposed to the outside.
- a solenoid 46 is fixedly mounted in the housing 11 and has an actuator 47 in the form of a plunger that moves linearly by the bias of the solenoid 46. Solenoid 46 is also fixed to its actuator 47 and has a pair of spaced projections.
- a spur gear 5 5 is connected to the output shaft 5 3 in a raised bottom space 54 formed by the raised bottom portion 51.
- a ring gear 56 is formed on the inner wall of the container 14 adjacent to the circular opening 15, and a spur gear is used to fit the reduced diameter portion 16 of the housing 11 into the circular opening 15 of the container 14. 5 5 meshes with the ring gear 5 6.
- a battery 57 used as a power source for the electric motor and the solenoid is housed in the housing 11.
- Reference numeral 58 denotes a jack into which the charger's electric cord is plugged to charge the battery 57, and a plug is inserted into the jack 58.
- Two light emitting diodes 59, 60 provided on the circuit board 41 are located in two holes 61 provided on the cover 13, one of the light emitting diodes 59 indicates the operation of the device, and the other 6 0 indicates battery charge.
- the injection needle 25 is attached to the syringe 23 by screwing the needle base 25 ′ into the end thread portion of the cartridge holder 24. If the needle 25 is to be unscrewed from the syringe 23 after the local anesthesia procedure, force the needle 25 through the circular opening 13 in the cover 13 with the needle 25 at the tip of the cartridge holder 24. Into the passage 20 of the support 21. At that time, the annular shoulder at the tip of the syringe 23 abuts on the annular ridge 39 around the central circular opening 37 of the movable disk 36.
- the piece 49 is moved and the arm 31 is pushed through the projections 48, 48 in the same direction as the movement of the piece 49, whereby the operating plate 28 is clocked. Rotate a predetermined angle in the surrounding direction. Due to the rotation of the operating plate 28, the chuck claws 26 that are insulated from the operating plate 28 are turned clockwise around the support pins 27 to close each other. When the syringe 23 is depressed, the needle base 25 'of the injection needle 25 attached to the end of the cartridge holder is at the position of the chuck jaw 26, so that the needle base 25' is closed. It is grabbed from three sides by 2 6.
- the chuck device is configured to rotate with the housing, a transmission mechanism for directly rotating the chuck device is not required at all, and the structure of the device is correspondingly simplified, and the entire device is reduced in weight. Become.
