Abstract

An electric multi-bottle infusion apparatus provided with a medicine-changing valve (9), an electric pushrod (10), and a controller (11). When a patient needs multiple medicinal solutions for an infusion therapy, a nurse connects multiple medicinal solution bottles (31) to the medicine-changing valve (9). When the medicinal solution of the first medicinal solution bottle (31) is depleted, either the patient or an accompanying person utilizes a remote control (30) of the controller (11) to control a pushrod valve core (14) of the electric pushrod (10) into moving, utilizes a solution-guiding hole (19) of the valve core (14) to connect the medicinal solution of the next medicinal solution bottle (31) to a solution-infusing apparatus (1), and utilizes the solution-infusing apparatus (1) for infusion of the patient. Such operation is repeated until the medicinal solution of the last medicinal solution bottle (31) is connected to the solution-infusing apparatus (1), thus solving the problem of nurse shortage.

The working principle of the electric multi-bottle infusion device according to claim 1, wherein: the working principle of the electric multi-bottle infusion device is: when working, the nurse will each of the electric dressing device The puncture joint is connected with each liquid medicine bottle; the liquid medicine of the first liquid medicine bottle is entered into the first infusion joint of the valve seat by the first puncture joint and the infusion catheter, and the liquid medicine is passed through the first infusion joint through the valve The liquid guiding hole of the core and the corresponding liquid outlet enter the liquid collecting chamber, and the liquid medicine entering the liquid collecting chamber enters the dripper of the infusion set from the liquid outlet of the valve seat and the liquid outlet conduit, and after being exhausted by the nurse, the infusion set is used. The patient performs infusion; when the first liquid medicine bottle is filled, the patient or the accompanying person uses the remote control to transmit the signal of the liquid change bottle to the controller, and the controller controls the electric push rod to push the valve core to the left. Move, move the liquid guide hole of the valve core from the position of the first infusion joint to the position of the next infusion joint, and the liquid medicine of the next bottle of the liquid medicine bottle enters the next one of the valve seat by the next puncture joint and the infusion catheter The infusion connector, the liquid medicine enters the liquid collecting chamber through the liquid guiding hole of the valve core and the corresponding liquid discharging port through the next infusion joint, and the liquid medicine entering the liquid collecting chamber enters the infusion liquid from the liquid outlet joint of the valve seat and the liquid outlet conduit. The dripper of the device carries the infusion of the next liquid bottle to the patient; meanwhile, when the first sensing member of the push rod moves to the position of the first inductive switch, the first inductive switch transmits its signal to the controller, the controller The push rod for controlling the electric push rod stops moving; when the liquid medicine infusion of the next liquid medicine bottle is completed, the patient or the accompanying person uses the remote controller to retransmit the next signal of the dressing liquid bottle to the controller, and the controller controls the electric push rod Push the valve core to move to the left again, and move the liquid guide hole of the valve core from the position of the next infusion joint to the position of the next infusion joint, and then the liquid medicine of the next bottle of the liquid medicine bottle is connected by the next puncture. And the infusion catheter enters the next infusion joint of the valve seat, and the liquid medicine enters the liquid collecting chamber through the liquid guiding hole of the valve core and the corresponding liquid discharging port through the infusion joint, and the liquid medicine entering the liquid collecting chamber is The outlet joint of the valve seat and the outlet conduit enter the dripper of the infusion set, and the patient is infused with the next liquid bottle; meanwhile, when the next sensing member of the push rod moves to the position of the next sensing switch, An inductive switch transmits its signal to the controller, and the controller controls the push rod of the electric push rod to stop moving; the patient or the accompanying person repeats the above operation until the last bottle of the liquid medicine bottle is finished, reducing the work of the nurse the amount.
