An infusion drop velocity monitoring system based on rfid dual tag sensing

Abstract

The invention discloses an infusion drip speed monitoring system based on RFID dual tag sensing, which includes: a passive drip speed sensor, a drip speed sensing integrated machine, a server platform and a drip speed sensing client; a passive drip speed sensor, and The dropper side wall contact setting of the infusion set includes: two RFID tags and a tag fixing bracket, the tag fixing bracket is composed of a back plate and two parallel and aligned splints, the back plate is embedded in two On the plywood, an accommodating space for embedding the dropper is formed between the two splints; two card slots for accommodating RFID tags are arranged in the backboard, and there are A groove, through which the RFID tag in the corresponding card slot leaks to the backboard, and the leaking part of the RFID tag clings to the surface of the dropper. By introducing a dual-label mechanism, the present invention can robustly monitor the drop rate of the infusion bottle / infusion bag under the condition of complex multipath interference in the environment.

Description

technical field [0001] The invention belongs to the technical field of RFID passive sensing and smart medical treatment, and particularly relates to an infusion drop velocity monitoring system based on RFID dual-tag sensing. Background technique [0002] In today's medical system, intravenous infusion is one of the most commonly used methods in clinical treatment. During the infusion process, it is very important for the liquid to flow into the vein at a specific drip rate. On the one hand, if the drip rate is too high, it will have adverse physiological effects on the patient, such as increased blood pressure and slowed heart rate. For patients with heart, kidney or liver problems, too fast drip rates can lead to hazards such as pulmonary edema. On the other hand, if the dripping rate is too low, for example, the infusion dripping rate becomes zero, the infusion process should end immediately or blood backflow may occur. The patient's infusion status only depends on the r...
