[0051] Specifically, the torsion spring 25 can make the pawl 22 intermittently contact and separate from the inner wall of the rotating groove 23 when the rotating ring 5 rotates. After the medicine bottle 1 is fixed, that is, after the rotating ring 5 stops rotating, the pawl 22 can be stuck in the rotating groove 23 under the elastic force of the torsion spring 25, so that the rotating ring 5 can be fixed, thereby preventing the medicine bottle 1 from falling.
[0052] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0053] Working principle of the present invention: when in use, when performing various medication operations in endocrine care, the barrel 3 covers the top of the medicine bottle 1 and is downward. After the barrel 3 contacts the desktop, or the rubber stopper 30 of the medicine bottle 1 is in the observation port 27, the sleeve of the syringe 2 is inserted from top to bottom into the connecting port 17. The connecting port 17 can limit the position of the syringe 2 to prevent the syringe 2 from deviating. After the needle 29 of the syringe 2 is inserted into the rubber stopper 30 of the medicine bottle 1, the injection or drug extraction operation can be performed. At this time, the hands of the staff can be prevented from contacting or approaching the medicine bottle 1 or the needle 29, so that the hands of the staff can be protected, which can greatly reduce safety hazards.
[0054] When mixing drugs for medicine bottles 1 of different sizes, repeat the above operation and make the syringe 2 and the medicine bottle 1 both located in the barrel 3. At this time, the wing plate 19 of the syringe 2 is stuck in the connecting groove 18. The staff member holds the connecting block 16 with his fingers, slightly lifts the barrel 3 and rotates the barrel 3, or directly rotates the connecting block 16. The rotation of the connecting block 16 can exert force on the adjusting block 21. The adjusting block 21 is subjected to the force so that the first column 15 drives the gear ring 28 to rotate. The rotation of the gear ring 28 can make the gear 13 cooperate with the mounting shaft 12 to rotate. The rotation of the mounting shaft 12 can make the rack 14 rotate. At this time, the positioning plate 9 can slide in the inner wall of the positioning port 10, and the medicine bottle 1 is fixed in the barrel 3. Then the injection can be performed to protect the staff member's hands.
[0055] When the protection plate 4 is close to the medicine bottle 1, the protection block 8 can slide in the inner wall of the protection groove 6. At this time, the compression of the first spring 7 can prevent the protection plate 4 from scratching or damaging the medicine bottle 1, and can protect the medicine bottle 1 and the device structure. When the medicine bottle 1 is fixed, the rotation of the first column 15 can make the rotating ring 5 rotate. At this time, the pawl 22 makes intermittent contact with the inner wall of the rotating groove 23. After the medicine bottle 1 is fixed, the reverse action of the first spring 7 is cooperated. At this time, the pawl 22 can be clamped in the rotating groove 23 to prevent the medicine bottle 1 from loosening;
[0056] After the medicine bottle 1 is fixed, the adjustment block 21 slides in the inner wall of the adjustment groove 20, so that the needle 29 can be directly inserted into the rubber stopper 30. At this time, the staff's hands can be prevented from contacting or approaching the medicine bottle 1 or the needle 29, and the staff's hands can be protected, which can greatly reduce safety hazards. In actual use, the equipment can also be placed in an automated equipment, that is, the medicine bottle 1 and the syringe 2 are placed on a conveyor belt for automatic installation, so that the lifting member is driven to fix the cylinder 3, and the cylinder 3 automatically presses down to buckle the medicine bottle 1, and the driving ring 5 rotates to fix the medicine bottle 1, and then the wing plate 19 and the connecting block 16 of the syringe 2 are pressed down to allow the needle 29 to pierce the rubber stopper 30, and finally the dispensing operation can be completed.
[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
