Problems solved by technology

In this process, nurses continuously operate the dispensing device to absorb and inject liquid, which is labor-intensive, low in efficiency, and prone to errors in manual operation
Moreover, the traditional dispensing device is exposed to the air for a long time, so that the dispensing push rod of the dispensing device is easily polluted during the dispensing operation. If bacteria are brought into the dispensing device, it is easy to cause contamination of the medicine; on the other hand , When dispensing medicine, nurses are required not to touch the dispensing pusher of the dispensing device with their hands. The operation is difficult and mistakes are inevitable, which increases the risk of drug contamination

Embodiment 1

[0047] Different from the aseptic dispensing system described above, this embodiment is different in that one end of the front push rod 41 is provided with an external thread, and the tail end of the rubber plug 2 is provided with a The internal thread joint corresponding to the external thread; through the front push rod 41 rotating around the axis while advancing, the external thread of the front push rod 41 is screwed with the internal thread joint of the rubber plug 2, so that the The front push rod 41 is combined with the rubber plug 2 .

Embodiment 2

[0049] Different from the above-mentioned aseptic dispensing system, the difference of this embodiment is that the aseptic dispensing system is also provided with a plurality of photoelectric position sensors and a photoelectric shutter that can move with the joint 6. Through the cooperation of the photoelectric position sensor and the photoelectric shutter 6, the on-off of the circuit can be realized to control the rotation of the push rod motor 31 and the rod head rotation motor 44; figure 1 As shown, when the photoelectric barrier 6 senses the first photoelectric position sensor 51, the front push rod 41 is at the farthest position from the syringe barrel 1, and the front push rod 41 does not extend into Inside the syringe barrel 1, at this time, the rubber plug 2 is located at the front end of the syringe barrel 1; figure 2 As shown, the front push rod 41 gradually extends into the interior of the syringe barrel 1 under the drive of the actuating part. When the photoelect...

Embodiment 3

[0051] Different from the aseptic dispensing system described above, the difference in this embodiment is that the front push rod 41 is placed in an aseptic structure, and the syringe barrel 1 is in a sealed connection with the joint. Therefore, when the front push rod 41 is pushed into the syringe barrel 1, it is in a sterile environment.

Abstract

The invention discloses a sterile dispensing system, used for achieving automatic dispensing in a sterile state. The sterile dispensing system comprises a medicine dissolving unit, a sterile unit and an actuating part, wherein the sterile unit is used for constructing a sterile environment, the sterile unit comprises a dispensing push rod and a sleeve rod, and the dispensing push rod is arranged in the sleeve rod; the actuating part is used for driving the dispensing push rod to advance or retreat; the dispensing push rod and the actuating part are in detachable connection; and the medicine dissolving unit and the sterile unit are in sealed connection. The sterile dispensing system, when applied to a dispensing operation, can emancipate medical personnel from dispensing work which is high in labor intensity and long in consumed time, so that working efficiency is improved and the labor intensity is reduced; and compared with a conventional manual dispensing operation which is easy to cause wrong, the sterile dispensing system can greatly reduce wrong operations due to manual operation in a process of automatically dispensing medicines, and subsequently, the occurrence of medical accidents can be avoided.

Description

technical field [0001] The invention relates to the field of dispensing devices, in particular to an aseptic dispensing system. Background technique [0002] At present, the most commonly used method of clinical infusion dispensing is manual dispensing. Nurses need to manually use syringes to mix the medicinal liquid, powder, etc. in the ampoule with other medicinal liquids, and then inject the mixed liquid into the infusion bottle or the patient. In this process, the nurse continuously operates the dispensing device to absorb and inject liquid, which is labor-intensive, low in efficiency, and prone to errors in manual operation. Moreover, the traditional dispensing device is exposed to the air for a long time, so that the dispensing push rod of the dispensing device is easily polluted during the dispensing operation. If bacteria are brought into the dispensing device, it is easy to cause contamination of the medicine; on the other hand , When dispensing medicine, nurses ar...
