Embodiment Construction

[0011] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, a medical infusion alarm device based on power line carrier communication includes a weighing module, a comparator, a power line carrier modulator, a power grid, a power line carrier demodulator and a nurse station. The weighing module monitors the weight value of the infusion bottle in real time, and feeds back to the comparator in real time. The comparator compares the measured data with the preset minimum weight value. When the measured data is less than or equal to the minimum weight value, it outputs a control The signal is sent to the power line carrier modulator, modulated into an electrical signal that can be transmitted on the power line, and transmitted through the power grid to the power line carrier demodulator at the receiving end, which demodulates the el...

Abstract

The invention discloses a medical transfusion alarming device based on power line carrier communication. The medical transfusion alarming device comprises a weight measurement module for measuring the weight of a transfusion medicine bottle and a comparer for comparing the weight of the transfusion medicine bottle with a preset value, the comparer is connected to a power grid through a power line carrier modulator-demodulator for modulating a digital signal into an electric signal capable of being transmitted in a power line, is connected with the power grid through a power line carrier modulator-demodulator for modulating the electric signal transmitted in a power line into the digital signal, and is connected with a nurse station. The medical transfusion alarming device has the advantages that a patient does not need to pay attention to reduction of the liquid face of a medicine and worry about blood vessel swelling, blood return and the like and can have a rest at ease, and it is also unnecessary to have a person special for accompanying a patient, so that burdens of family members of the patient are reduced. Besides, the power line is only needed between the comparer and the nurse station, and data information transmission can be completed through the 220V power grid. A systematical structure is simple, and cost is low.

Description

technical field [0001] The invention relates to the field of clinical medicine, in particular to a medical transfusion alarm device based on power line carrier communication. Background technique [0002] The existing sick bed call system work flow is: 1. When the patient needs help, press the call key of the sick bed extension and wait for the nurse to answer. 2. After the bed extension calls, the nurse station host will receive the call information, and the nurse station personnel will talk to the patient after answering and then go to help. This system is basically adopted in the market at present. This system seems to be convenient, but it ignores one point, that is, the patient itself is the object to be taken care of, and many patients cannot press the call button in time when they need help, especially when the patient is weak and often falls asleep during the infusion, which leads to The consequence is that after the medicine in the medicine bottle is transfused an...
