Further, the mobile terminal is a mobile phone, a tablet computer or a notebook computer.

Further, the infrared through-beam photoelectric sensor is composed of two parts: a transmitting tube and a receiving tube.

The beneficial effects of the utility model are:

1. The infusion monitoring node uses the weight sensor and the infrared light sensor to collect the liquid medicine data at the same time, and performs fusion analysis and processing in the infusion monitoring center. Compared with a single sensor, it not only has higher accuracy, but also can obtain the overall progress information and Specific drip rate information.

2. The infusion monitoring node and the infusion control center adopt ZigBee wireless communication mode. ZigBee has the advantages of low power consumption, low cost, and large capacity. Compared with traditional wired networking methods, it has flexible layout, convenient networking, and good scalability. specialty.

3. Not only the alarm prompt function is set in the infusion monitoring node and the infusion monitoring center, but also the real-time status of the infusion recipient can be checked on the mobile terminal, so as to avoid the problem of medical staff staring at the screen, so that the medical staff can know the status of each patient anytime and anywhere The infusion situation can be handled in a timely manner, and the patient's family members can also query the patient's infusion progress through the mobile terminal, so as to reasonably arrange their own schedule and realize unaccompanied infusion.

4. The detailed infusion data of each patient is stored and managed centrally on the server, so that there is data to rely on, which provides a guarantee for avoiding doctor-patient disputes.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1-3, a wireless infusion monitoring system includes several infusion monitoring nodes, an infusion monitoring center, and several mobile terminals; the infusion monitoring node realizes the comprehensive monitoring of the infusion progress and speed, and the infusion monitoring The comprehensive processing and management of node data, the mobile terminal access monitoring center to query the patient's infusion situation in real time, all three parts are connected through wireless.

As shown in Figure 2, described infusion monitoring node comprises single-chip microcomputer, power supply, weight sensor 2, infrared photoelectric sensor 4, manual alarm button, sound and light alarm and ZigBee emission module; Described power supply, weight sensor 2, infrared The through-beam photoelectric sensor 4, the manual alarm button, the sound and light alarm and the ZigBee transmitting module are all connected with the single-chip microcomputer;

As shown in Figure 3, described infusion monitoring center comprises ZigBee receiving module, computer and server; Described ZigBee receiving module is connected with the ZigBee transmitting module of infusion monitoring node by wireless; Described ZigBee receiving module is connected with computer, and described computer connect to the server;

The mobile terminal is a mobile phone, a tablet computer or a notebook computer; the mobile terminal is connected to the server through wireless.

As shown in Figure 1, the weight sensor 2 is composed of a force sensor. During specific implementation, the weight sensor 2 is connected between the infusion bag 3 and the infusion stand 1, and the single-chip microcomputer converts the received gravity signal into the remaining amount of the medicinal solution. ; The infrared photoelectric sensor 4 is composed of two parts, the transmitting tube and the receiving tube. The electric signal of the infrared receiving tube will change due to the absorption and scattering of the infrared light by the drops. The dripping speed of the liquid medicine and whether it has been dripped can be judged by detecting the frequency of the change of the electric signal.

As shown in Figure 2, the single-chip microcomputer transmits the data collected by the weight sensor 2 and the infrared photoelectric sensor 4 to the infusion monitoring center through the ZigBee transmitting module. When the single-chip microcomputer detects that the dripping speed value of the medicine exceeds the limit or the dripping of the medicine is not detected, the sound and light alarm will be activated to remind the infusion user of abnormal conditions, and at the same time, an alarm message will be sent to the monitoring center to notify the doctors to deal with it in time. During the infusion process, if the patient needs other help, he can also send a help message to the monitoring center through the manual alarm button.
