Syringe needle feeding and rotating mechanism

Abstract

The invention discloses a syringe needle feeding and rotating mechanism which comprises a first fixing plate, a second fixing plate, a lead screw connected between the first fixing plate and the second fixing plate through a first bearing, a motor connected to the second fixing plate, and a first belt pulley structure connected between the motor and the lead screw; the mechanism further comprisesa third connecting plate connected to the second fixing plate, and a rotating sleeve connected to the third fixing plate through a second bearing and used for positioning an outer cylinder of a syringe, and a pull plate assembly connected to the lead screw, used for positioning a piston rod of the syringe and being capable of driving the piston rod of the syringe to move back and forth in the linear direction; a second belt pulley structure is connected between the rotating sleeve and the lead screw; a placement space for the outer cylinder of the syringe and the piston rod of the syringe is formed between the rotating sleeve and the pull rod assembly; liquid medicine can be pumped and drained, the syringe is driven to simulate manual operation to complete medicine dosage, and the mechanism is safe, reliable and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of the manipulator part of the syringe dispensing structure in an automatic dispensing device, in particular, to a needle feeding and rotating mechanism for a syringe. Background technique [0002] With the substantial improvement of people's living standards and the continuous development of the hospital HIS network, the nationals have put forward higher requirements for the improvement of hospital management, especially the improvement of dispensing management; According to the requirements of hospital accreditation, the ward dispensing room should implement single-dose drug dispensing and intravenous drug preparation. The current dispensing process in the ward dispensing room is far from fully meeting the above requirements. The main reasons are as follows: 1. The risk of cross-infection: during the dispensing During the process and checking process, pharmacists will be consciously or unconsciously in con...

[0002] With the substantial improvement of people's living standards and the continuous development of the hospital HIS network, the nationals have put forward higher requirements for the improvement of hospital management, especially the improvement of dispensing management; According to the requirements of hospital accreditation, the ward dispensing room should implement single-dose drug dispensing and intravenous drug preparation. The current dispensing process in the ward dispensing room is far from fully meeting the above requirements. The main reasons are as follows: 1. The risk of cross-infection: during the dispensing During the process and checking process, pharmacists will be consciously or unconsciously in contact with medicines to complete the deployment; it may cause contamination of medicines; 2. High error rate: the current dispensing process, verification and confirmation methods largely rely on medicines Doctors and nurses' mastery of drug knowledge, the increase of beds and a large number of adjustment work before holidays make it even more difficult to fully discover problems in the check under fatigue; Insufficient manpower and funds, etc.); therefore, a modern automatic dispensing device is required; for the syringe (syringe), it is generally used to manually grasp the syringe to absorb the medicine, which is likely to cause cross-infection during the period, and there are potential safety hazards
