Detailed Description

The present invention will be described in further detail below.

As shown in fig. 1 and 2, a full-automatic treatment device for medical syringe needles comprises a positioning jig 3, an upper cover plate assembly 2, a lower support plate assembly 4, a crimping assembly 5, a clamping device 6, a collecting assembly 7, a syringe sensor 8 and the like.

A needle clamp is arranged below the positioning jig 3 and is used for clamping the syringe needle 11.

As shown in fig. 3-7, the crimping assembly 5 includes a rotary device drivingly connected to the needle holder for urging the needle holder to rotate circumferentially to crimp the syringe needle 11, and a translational drive device; a jacking block 513 is correspondingly arranged on one side of the needle head clamp, and the jacking block 513 is fixedly connected with the positioning jig 3; the translation driving device is fixedly connected to the positioning fixture 3 and connected to the needle clamp and is used for driving the needle clamp to move towards the top block 513 so that the curled syringe needle 11 is separated and separated from the needle clamp after being propped against the top block 513.

When the medical syringe is used, the discarded medical syringe 1 is placed in the positioning jig 3 downwards, and the syringe is positioned in the positioning jig 3. After the needle holder holds the syringe needle 11, the rotating means drives the needle holder to rotate circumferentially, causing the syringe needle 11 to curl on the needle holder. After crimping to a certain extent, the syringe needle 11 is separated from the syringe barrel and the rotation means stops rotating. The translational drive means then drives the needle holder towards the top block 513 and the curled syringe needle 11 is not able to follow the needle holder further after it has been pushed against the top block 513. As the needle holder continues to move, the needle holder is withdrawn from the blocked syringe needle 11, causing the syringe needle 11 to drop down, thereby effecting automatic disengagement of the syringe needle 11. Need not medical personnel manual work and take off the syringe needle of curling from needle holder, avoided the manual work to take off the risk of being injured when syringe needle 11 from needle holder, improved security and convenience, be favorable to liberating medical staff's both hands, improve medical staff's work efficiency.

In the prior art, after the syringe needle 11 is separated from the syringe needle cylinder, the syringe needle cylinder is clamped on the positioning jig 3, and the syringe needle cylinder needs to be taken out of the positioning jig 3 manually for discarding, so that the operation is inconvenient.

In this embodiment, the positioning fixture 3 is provided with a channel adapted to the outer diameter of the syringe barrel, a clamping device 6 with an adjustable clamping size is arranged between the lower end of the channel and the needle clamp, when the clamping size is reduced, the clamping device 6 clamps the syringe needle 11 and abuts against the lower end of the syringe barrel, and when the clamping size of the clamping device 6 is larger than the outer diameter of the syringe barrel, the syringe barrel falls off from the clamping device 6.

The channel in the positioning jig 3, which is adapted to the outer diameter of the syringe needle cylinder, has a self-adapting function, and when medical staff throw the medical syringe 1 into the positioning jig 3, the medical syringe 1 is automatically adjusted to a state that the syringe needle 11 is vertically downward in the positioning jig 3. The clamping size of the clamping device 6 below the channel is reduced to be slightly larger than the outer diameter of the syringe needle 11 in advance, and when the medical syringe 1 slides from the channel of the positioning jig 3, the clamping device 6 clamps the syringe needle 11 and abuts against the lower end of the syringe needle cylinder, so that the medical syringe 1 is hung in the clamping device 6 in a penetrating way. The needle holder under the holding means 6 then holds the syringe needle 11 and starts to curl rotationally. Since the clamping device 6 is abutted against the lower end of the syringe barrel, the syringe needle 11 is separated from the syringe barrel along with the continuous curling of the syringe needle 11. When the syringe needle 11 is released from the needle holder, the holding size of the holding means 6 is increased to be larger than the outer diameter of the syringe barrel, and the syringe barrel is automatically dropped downward from the holding means 6. The separated syringe needle cylinder is taken out from the positioning jig 3 without manual work, and the operation is more convenient. The clamping device 6 can not only play a role in positioning the syringe needle 11, but also can prop against the syringe barrel when the syringe needle 11 is pulled out, and provide a fixing force for pulling out the syringe needle 11 by the needle clamp, so that the separation of the syringe needle 11 and the syringe barrel is facilitated.

The needle clamp comprises two crimping bars 53 with adjustable relative distance, a square rod 512 is arranged between the two crimping bars 53, the two crimping bars 53 are provided with grooves corresponding to the square rod 512, the grooves are approximately U-shaped, the shapes of the grooves are matched with those of the square rod 512, two rod heads are arranged at intervals between the square rod 512, the two crimping bars 53 are clamped between the two rod heads, and the outer diameters of the rod heads are larger than the inner diameters of the grooves. When the two curling bars 53 clamp the syringe needle 11, the grooves of the two curling bars 53 are respectively clamped with the square rod 512, the square rod 512 is hinged to a translation driving device, and a rotating device is connected to the square rod 512 in a driving mode.

Specifically, the translation driving device is a translation electric push rod 51 fixedly connected to the positioning fixture 3. The rotating device is a curling motor 511, and a motor base of the curling motor 511 is fixedly connected to a push rod of the translation electric push rod 51. The curling motor 511 is connected to the square bar 512 through a curling gear set 52 to drive the square bar 512 to rotate. The gears on the square rods 512 are provided with circular holes, and the tail ends of the translation electric push rods 51 are hinged to the circular holes. With this structure, the motion of the curl motor 511 does not interfere with the translation of the electric push rod 51. When the two curling bars 53 clamp the syringe needle 11, the curling motor 511 acts to drive the square rod 512 to rotate, the square rod 512 is clamped in the grooves of the two curling bars 53 to drive the curling bars 53 to rotate, and meanwhile, the translational electric push rod 51 is kept stationary.

When the needle 11 is curled and separated from the syringe barrel, the curling motor 511 stops, the translational electric push rod 51 horizontally retracts, the curling motor 511 moves along with the retraction of the translational electric push rod 51, and the square rod 512 drives the curling rod 53 to move towards the top block 513 through the rod head, and the needle 11 is separated from the curling rod 53 after being propped against the top block 513. At the time of resetting, the translation electric push rod 51 horizontally extends, the curling motor 511 moves along with the extension of the translation electric push rod 51, and meanwhile, the square rod 512 pushes the curling rod 53 to move back to the top block 513 through the rod head, so that the curling rod 53 is reset to the initial position.

Specifically, the distance-adjusting electric push rod 510 is fixedly connected to the positioning fixture 3, and is used for driving the guide block 56 to move linearly. One end of the curling rod 53 is correspondingly provided with a thrust bearing, the lower part 59 of the thrust bearing is fixedly connected with the positioning jig 3, and the bottom surface of the movable connecting block 57 is abutted against the upper part 58 of the thrust bearing.

When the distance-adjusting electric push rod 510 acts, the guide block 56 drives the curling bars 53 and the movable connecting blocks 57 to linearly move on the upper part 58 of the thrust bearing, so that the distance between the two curling bars 53 is adjusted. When the two curling bars 53 clamp the syringe needle 11, the arc shapes of the arc grooves of the two guide blocks 56 are on the same circle, so that the movable connection block 57 can smoothly rotate.

When the curling motor 511 is operated, the curling rod 53 and the movable connecting block 57 are driven to rotate on the upper portion 58 of the thrust bearing, so that the curling of the syringe needle 11 on the curling rod 53 is realized. When the translation motor push rod 51 is retracted, the curling bars 53 are driven to be pulled away from the movable connecting block 57. Upon reset, the electric push rod 51 is translated to extend forward, reinserting the crimp rod 53 into the movable connection block 57.

In this embodiment, the number of the top blocks 513 is 2, and the top blocks are symmetrically arranged on one side of the 2 curling bars 53. The top block 513 is provided with a guide rail 54, and the extending direction of the guide rail 54 is perpendicular to the curling bars 53. The curling bar 53 is fixedly provided with a universal wheel 55, and the universal wheel 55 is connected with the guide rail 54 in a rolling way. With this structure, the curling bars 53 are supported at two positions of the universal wheel 55 and the movable connecting block 57 at the same time, so that the stress is more balanced and the movement is more stable.

When the clamping electric push rod 61 is retreated relative to the clamping jaw 64, the first inclined connecting rod 631 and the second inclined connecting rod 632 are driven to rotate inwards to retract, so that the distance between the two clamping jaws 64 is reduced, the two clamping jaws 64 can clamp the syringe needle 11,

when the clamping electric push rod 61 advances relative to the clamping jaw 64, the first inclined connecting rod 631 and the second inclined connecting rod 632 are driven to rotate outwards to expand, so that the distance between the two clamping jaws 64 is increased. When the distance between the two clamping jaws 64 is larger than the outer diameter of the syringe barrel, the syringe barrel falls from between the two clamping jaws 64, so that the trouble of manually discarding the syringe barrel is avoided, and the syringe barrel is more convenient to use.
