[0017] Compared with the prior art, the advantages and positive effects of the present invention are:

[0018] 1. In the present invention, an anti-bending device is provided. When the device needs to be used, the bolt is first loosened and the bolt is screwed out from the inside of the threaded hole. The bolt and the threaded hole are separated so that the displacement plate loses its limit in the inside of the groove. At this time, the displacement plate can be moved. The movement of the displacement plate in the groove drives the slide plate to move on the surface of the slide rod. The movement of the slide plate on the surface of the slide rod drives the first ring to move. The movement of the first ring drives the support arm and the second ring to move. When the second ring moves to a position so that it is sleeved on the surface of the connector of the syringe, the bolt is screwed into the corresponding threaded hole again to fix the position of the displacement plate in the groove at this time. Then, the infusion tube is inserted into the And the connector of the syringe, at this time, the first ring and the second ring are used to fix the infusion tube through the middle support arm, so that the infusion tube is not easy to bend and remains straight, and then the button on the surface of the shell is used to control the rotation of the first threaded rod. The rotation of the first threaded rod drives the movable seat to move on the surface of the round rod, and the movable seat moves on the surface of the round rod to push the piston of the syringe to move, so that the medicine inside the syringe is transported into the inside of the infusion tube, and then transported into the patient's body through the inside of the delivery tube to complete the infusion operation. Through the cooperation of the above structure, it is avoided that the connection between the infusion tube and the syringe connector is bent, thereby keeping the infusion unobstructed.

[0019] When the syringe is replaced, the movable plate is first slid to move inside the strip groove. The movement of the movable plate inside the strip groove squeezes the spring, causing the spring to be compressed. At the same time, the movement of the movable plate inside the strip groove also drives the insertion rod to move. The insertion rod moves to move itself out of the inside of the insertion hole. The insertion rod and the insertion hole are separated, causing the rotating shaft to lose its limit. At this time, the long plate can be rotated. The rotation of the long plate causes the first and second rings to move away from the front of the syringe connector. When the long plate is rotated to a suitable angle, the movable plate is released, and the spring's rebound force is used to re-insert the insertion rod into the corresponding insertion hole, thereby re-limiting the rotation of the rotating shaft. Through the cooperation of the above structure, the positions of the first and second rings can be changed, thereby preventing the first and second rings from blocking the front of the syringe connector and affecting the replacement operation of the syringe connector.

[0020] 3. In the present invention, by providing an angle adjustment device, when the angle of the shell needs to be adjusted during specific use, the electric telescopic rod is first started, and the electric telescopic rod is started to drive the movable block to move inside the movable groove, and the movable block moves inside the movable groove to drive the connecting rod to move, and the connecting rod moves to drive the slide plate to move inside the long groove, and the slide plate moves inside the long groove to drive the rack to move, and the rack moves and engages with the gear, thereby causing the gear to rotate, and the gear rotation drives the rotating rod to rotate, and the rotating rod rotation drives the rotating block to rotate, and the rotating block rotation drives the shell to rotate. When the shell rotates to a suitable position, the electric telescopic rod can be closed. Through the cooperation of the above structure, the placement angle of the shell can be adjusted accordingly according to the patient's injection angle, thereby further improving the practicality of the device.

[0021] 4. In the present invention, by setting a lifting device, when the beds in the ward are tight and the patient needs to sit on the chair for infusion, the motor can be started at this time. The motor starts and drives the second threaded rod to rotate. The rotation of the second threaded rod drives the sliding plate to move inside the vertical groove. The movement of the sliding plate inside the vertical groove drives the U-shaped seat to move. The movement of the U-shaped seat drives the top rod to move outward from the inside of the sleeve. At the same time, the movement of the U-shaped seat eventually drives the shell to move. When the shell moves to a suitable height, the motor can be turned off. Through the cooperation of the above structure, the height position of the shell can be adjusted, so that the device can meet the two situations of patients receiving infusion on the bed or on the chair.

[0052] Working principle: By setting the anti-bending device 2, when the device needs to be used, first loosen the bolt 214 and screw the bolt 214 out from the inside of the threaded hole 215. The bolt 214 and the threaded hole 215 are separated so that the displacement plate 213 loses its limit in the inside of the groove 212. At this time, the displacement plate 213 can be moved. The displacement plate 213 moves inside the groove 212, driving the slide plate 208 to move on the surface of the slide rod 207. The slide plate 208 moves on the surface of the slide rod 207, driving the first ring 209 to move. The movement of the first ring 209 drives the support arm 210 and the second ring 211 to move. When the second ring 211 moves to a position so that it is sleeved on the connector surface of the syringe 10, the bolt 214 is screwed into the corresponding threaded hole 215 again to fix the displacement plate 2. 13 At this time, the position inside the groove 212 is then used to connect the infusion tube and the joint of the syringe 10. At this time, the first ring 209 and the second ring 211 are used to fix the infusion tube through the middle support arm 210, so that the infusion tube is not easy to bend and remains straight. Then, the button on the surface of the shell 1 is used to control the rotation of the first threaded rod 6. The rotation of the first threaded rod 6 drives the movable seat 8 to move on the surface of the round rod 7. The movable seat 8 moves on the surface of the round rod 7 to push the piston of the syringe 10 to move, so that the medicine inside the syringe 10 is transported into the inside of the infusion tube and then into the patient's body through the inside of the delivery tube to complete the infusion operation. Through the cooperation of the above structure, it is avoided that the connection between the infusion tube and the syringe 10 joint is bent when connected, thereby keeping the infusion unobstructed. When the connector of the syringe 10 needs to be replaced, first slide the movable plate 32 to move the movable plate 32 inside the strip groove 31. The movement of the movable plate 32 inside the strip groove 31 will squeeze the spring 36, so that the spring 36 is compressed. At the same time, the movement of the movable plate 32 inside the strip groove 31 also drives the insertion rod 33 to move. The insertion rod 33 moves so that it moves out of the inside of the socket 34. The insertion rod 33 and the socket 34 are separated so that the rotating shaft 203 loses its limit. At this time, the long plate 205 can be rotated. The long plate 205 rotates to make the first ring 209 and the second ring 211 are moved away from the front of the connector of the syringe 10. When the long plate 205 is rotated to a suitable angle, the movable plate 32 is released, and the rebound force of the spring 36 is used to reinsert the insertion rod 33 into the corresponding insertion hole 34, so as to re-limit the rotation of the rotating shaft 203. Through the cooperation of the above structure, the positions of the first ring 209 and the second ring 211 can be changed, thereby avoiding the first ring 209 and the second ring 211 blocking the front of the connector of the syringe 10 and affecting the replacement operation of the connector of the syringe 10.When it is necessary to adjust the angle of the shell 1 during specific use, the electric telescopic rod 414 is first started. The electric telescopic rod 414 is started to drive the movable block 411 to move inside the movable groove 410. The movable block 411 moves inside the movable groove 410 to drive the connecting rod 412 to move. The connecting rod 412 moves to drive the slide plate 407 to move inside the long groove 406. The slide plate 407 moves inside the long groove 406 to drive the rack 408 to move. The rack 408 moves and engages with the gear 409, thereby causing the gear 409 to rotate. The rotation of the gear 409 drives the rotating rod 404 to rotate. The rotation of the rotating rod 404 drives the rotating block 405 to rotate. The rotation of the rotating block 405 drives the shell 1 to rotate. When the shell 1 is rotated to the appropriate position, the electric telescopic rod 414 can be closed. Through the cooperation of the above structure, the placement angle of the shell 1 can be adjusted accordingly according to the injection angle of the patient, thereby further improving the practicality of the device. When there are not many beds in the ward and the patient needs to sit on the chair for infusion, the motor 53 can be started. The motor 53 starts to drive the second threaded rod 52 to rotate. The rotation of the second threaded rod 52 drives the sliding plate 55 to move inside the vertical groove 54. The sliding plate 55 moves inside the vertical groove 54 to drive the U-shaped seat 403 to move. The movement of the U-shaped seat 403 drives the top rod 402 to move outward from the inside of the sleeve 401. At the same time, the movement of the U-shaped seat 403 also drives the shell 1 to move. When the shell 1 moves to a suitable height, the motor 53 can be turned off. Through the cooperation of the above structure, the height position of the shell 1 can be adjusted, so that the device can meet the two situations of whether the patient is receiving infusion on the bed or on the chair.
