When the plate drives the medicine bottle to rotate to the left and touches the first travel switch, the first travel switch is triggered, that is, the stepping motor is reversely rotated by the triggering action of the first travel switch, that is, the stepping motor drives the rotating shaft to drive the oscillating plate to Rotate to the right, when the oscillating plate touches the second travel switch to the right, the second travel switch is triggered, that is, the stepper motor rotates in the opposite direction again through the triggering effect of the second travel switch, and finally through the left and right reciprocating motion of the above oscillating plate , which can realize the left and right shaking of the medicine bottle, that is, to promote the uniform mixing effect of the chemotherapy drugs inside the medicine bottle, effectively avoiding the problem of insufficient drug mixing affecting the follow-up drug effect. 2. When the patient needs infusion; first, the medical staff will install the hole Screw into the upper end of the existing infusion stand, that is to realize the connection and fixation of the device and the infusion stand, and then the medical staff put the uniformly mixed liquid medicine bottle into the placement groove on one side of the shell, that is, through the function of the avoidance groove, it can Realize the exposure of the bottom of the infusion bottle, then connect the infusion tube to the infusion bottle, and then perform infusion on the patient. At the same time, put another bottle of spare medicine solution into the storage tank on the other side, and then turn on the first switch , that is, the stepping motor drives the rotating shaft to drive the oscillating plate to reciprocate and slightly oscillate left and right. At this time, through the above, it can ensure that the spare medicine is in the best mixed state and improve the effect of subsequent infusion. At the same time, in order to prevent the sealing plate from blocking the observation of medical staff The line of sight of the medicine bottle, the sealing plate is made of transparent material, which can be easily observed. In addition, the medical staff can turn on the second switch in advance to trigger the pressure sensor to open, that is, when the medicine liquid infusion in a bottle of medicine is completed, the medicine will be released. The weight of the bottle is reduced, so that the spring can push the supporting plate to move upwards. When the pressure sensor is touched, that is, when the pressure value detected by the pressure sensor is lower than the original set value, the reminder light will be on. At this time, the reminder light will be on, so as to facilitate medical care. The timely replacement of drugs by personnel improves the accuracy and safety of patient treatment. The drug dissolving device for chemotherapy has an ingenious structure and powerful functions. First, the design of the oscillation mechanism can promote the mixing effect of chemotherapy drugs and effectively avoid drug mixing. Insufficient, thus affecting the follow-up drug effect, secondly, through the cooperation effect of the fixed hanging device and the standby drug dissolving mechanism, the follow-up drug solution can be dissolved and oscillated during the infusion process, which can ensure that the standby drug is in the best mixed state, improving the The effect of the follow-up infusion finally passed the above, thus greatly improving the practicability and benefiting the popularization and application of clinical chemotherapy. For energy supply, the handle is to facilitate the medical staff to carry and hold the device.
