Embodiment 1

[0045]Embodiment 1: This infusion alarm based on the weighing method wireless sensing technology includes an upper computer and a lower computer;

[0046] The lower computer includes terminal data acquisition and monitoring equipment and a router module, and the upper computer includes a wireless signal receiving coordinator and an upper computer PC;

[0047] The terminal data acquisition and monitoring equipment of the lower computer is connected with the wireless signal receiving coordinator of the upper computer through a router module, the wireless signal receiving coordinator is connected with the upper computer PC, and the terminal data acquisition and monitoring equipment is used for collecting, Monitor and transmit infusion information, the wireless signal receiving coordinator is used to receive the data information transmitted by the terminal data collection and monitoring equipment, and transmit the data information to the upper computer PC, the infusion alarm softwa...

Embodiment 2

[0065] Embodiment 2: The structure of this embodiment is the same as that of Embodiment 1. The difference is that the distance between the lower computer and the upper computer in this embodiment is relatively close, and it does not need to be connected through a router module. The terminal data collection and monitoring equipment of the lower computer is connected to the upper computer. The wireless signal receiving coordinator of the machine is directly connected.

[0066] In this embodiment, the initial value of the droplet is determined by judging the weight collected for the first time and sent to the CC2530 chip 9. When the collected data is converted into weight by multiplying the conversion coefficient and then divided by the liquid density greater than 500mL, the CC2530 chip 9 automatically calculates the initial value of the droplet. The value becomes 500mL. When the collected data is multiplied by the conversion factor and converted to weight divided by the liquid de...

Abstract

The invention discloses an infusion alarm based on weighing-process wireless sensing technology. A lower computer comprises terminal data collecting and monitoring equipment and a router module, an upper computer comprises a wireless signal receiving coordinator and an upper computer PC, the terminal data collecting and monitoring equipment of the lower computer is connected with the wireless signal receiving coordinator of the upper computer or connected with the same through the router module, and the wireless signal receiving coordinator is connected with the upper computer PC. Through weighing means and wireless communication technology, the limitation problem that infusion monitoring alarms work in a single-end manner is overcome, and the problem of inaccurate measuring due to patientmovement, the problem of difficult in wiring during network forming and the problem that detection instruments contact with liquid drops in monitoring mode are solved to great extent.

Description

technical field [0001] The invention relates to a transfusion alarm based on weighing method wireless sensing technology, which belongs to the technical field of wireless electronic transmission. Background technique [0002] In our country, currently on the market monitoring infusion alarm, the mainstream includes the weighing method, electrode method, blocking method and infrared monitoring and other methods to achieve monitoring and alarm by measuring drip weight, monitoring electrodes, and optical principles. There are advantages, but each has its own disadvantages. Some measurement methods require contact with liquid droplets, such as the monitoring electrode method, so there is a risk of liquid contamination, which requires additional disinfection and other processes, and the risk cannot be completely avoided. However, some methods have relatively large limitations. For example, the infrared method has poor anti-interference ability, and it is easy to cause inaccurate ...
