The automatic liquid changing device comprises a transmission device, a first prime mover, a second prime mover, asecond rotating shaft and a retainer, the second rotating shaft is connected with a medicine bottle retainer, the medicine bottle retainer comprises a plurality of fixing areas, and the fixing areasare used for fixing products; the first prime mover and the second prime mover are both connected in the retainer, the first prime mover works to drive the second rotating shaft to rotate, the secondrotating shaft rotates to drive the retainer to rotate, a plastic steel needle clamping mechanism is further connected in the retainer, and the second prime mover drives a plastic steel needle in theplastic steel needle clamping mechanism to move up and down through the transmission device; a control module is further connected in the retainer and comprises a single-chip microcomputer and a liquid drop detection alarm device, and the single-chip microcomputer, the liquid drop detection alarm device, the first prime mover and the second prime mover are in signal connection; according to the device, the dropping liquid allowance can be detected, a medicine bottle can be automatically replaced, and the workload of medical staff is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic liquid exchange device for intravenous infusion. Background technique [0002] Intravenous infusion therapy is a commonly used treatment method in clinical medical work, and many patients need to infuse several groups of liquid medicine a day. Due to the long infusion time (generally more than 1.5 hours) and the large infusion volume (many patients generally infuse several sets of liquid medicine every day), this is a great psychological burden for the patient and his accompanying staff, which is not conducive to the patient's recuperation , It is also easy to "mistake". If the liquid is not detected in time after infusion, and the medical staff cannot change the dressing or pull out the needle in time, air will enter the blood vessel to form an air embolism or blood backflow. If it is mild, it will delay treatment and cause pain to the patient; if it is ...

AI Technical Summary

Problems solved by technology

Although most hospitals have installed the ward paging and intercom system, it only solves the problem of communication between doctors and patients, and the psychological pressure caused by the infusion has not been relieved in the slightest.
