Medical automatic liquid change infusion frame

Abstract

The invention provides a medical automatic liquid change infusion frame. The medical automatic liquid change infusion frame comprises a liquid change frame, a transmission box, a supporting frame andthe like, a driving motor is excited by an electrical signal of a camera or a laser sensor, the driving motor rotates by four circles in each motion, that is, the four circles rotated by the driving motor form a cycle, connection and disconnection of different wheel systems and graduation mechanisms are controlled through a gear shift mechanism similar to a vehicle transmission, then motions of lifting, rotating and lowering of the liquid change frame are achieved, and since a needle head is fixed, the motions correspond to the motions of drawing out the needle head, changing a drug bottle andinserting the needle head respectively. The camera is used a monitoring sensor, whether drug liquid in an infusion bottle is totally infused or not can be timely found, double guarantee is provided through the laser sensor, when working errors occur to the camera, a pipe can be pinched timely to stop infusion, and even if a patient falls in sleep, danger cannot occur.

Description

technical field [0001] The invention relates to the technical field of medical robots, in particular to a medical automatic liquid-changing infusion stand. Background technique [0002] Infusion (intravenous drip) is one of the commonly used treatment methods in modern medicine. With the continuous increase of the number of infusions in the hospital, the workload of doctors is also increasing. Most patients need to infuse 2-3 bottles of liquid medicine at a time. For drug interactions, physiological saline for flushing may be added between each two drugs, which is equivalent to infusing 3-5 bottles of liquid medicine. Every time a bottle is infused, the doctor needs to change it, that is, pull out the needle from the empty bottle and insert it into a new bottle. This action is not complicated, but it needs real-time supervision, especially when the patient is asleep. Under normal circumstances, if no one is looking after it, dangerous situations such as air entering the bod...

Every time a bottle is infused, the doctor needs to change it, that is, pull out the needle from the empty bottle and insert it into a new bottle. This action is not complicated, but it needs real-time supervision, especially when the patient is asleep. If left unattended, there will be dangerous situations such as air entering the body
