Embodiment Construction

[0038] The wireless sensors of the multi-bed fetal monitor are divided into two types: wireless ultrasound probe and wireless uterine contraction pressure probe. The working principles of the two probes are briefly introduced as follows:

[0039] Such as figure 1 As shown, the wireless ultrasonic probe, the power supply part is powered by lithium battery 104, the power management chip 103 converts and various voltage power supplies required on the circuit, and the external power supply interface 102 is used for charging the external power supply, and the probe MCU101 controls the CPLD105 to generate pulses After the signal is amplified by the ultrasonic transmitting circuit 106, it excites the ultrasonic chip 107 to send ultrasound to the fetal heart, and the reflected echo signal is converted into an electrical signal by the ultrasonic chip 107. After being amplified by the amplifier circuit 108, the echo signal is demodulated with the local oscillator signal sent by the CPLD1...

Abstract

The invention provides a management control method and system of wireless sensors for a multi-bed fetal monitor. The method includes the steps of receiving and storing status data, entering query information, performing selecting and allowing prompting. The method and the system have the advantages that residual power of all wireless sensors in a current probe charging cavity can be monitored in real time; before a doctor or a nurse needs to perform fetal monitoring on a pregnant woman, a current phase, outpatient status, expectant status or partition status, of the pregnant women is automatically recognized to automatically judge the more proper one of the wireless sensors; the doctor can select a twins state and determine whether or not a TOCO pressure probe is required; the system integrates the judgments above, turns on LED lights around the wireless sensor and reminds a user of taking the required wireless sensor, a display screen of the wireless sensor is on, and the wireless sensor is available; excess detection is avoided for the doctors or nurses, the required fetal monitoring can be performed just after the wireless sensors turned on are removed, and chances of error are slimmed.

Description

technical field [0001] The invention relates to the field of medical fetal monitoring, in particular to a wireless sensor management and control method and system for a multi-bed fetal monitor. Background technique [0002] The traditional fetal monitor is a one-to-one monitor. A monitor is placed next to each pregnant woman. The probe is tied to the belly of the pregnant woman. There are 2 fetal heart rate probes and 1 uterine pressure probe. The 3 wires are easy to be entangled. Together, and pregnant women can’t move around freely, the fetal monitor must be taken off when leaving the fetal monitor, and it needs to be put on again when returning, which is very inconvenient to use. A fetal monitor is required next to each bed in a ward, which occupies the area of ​​the department. Uses more power. [0003] At present, there are multi-bed fetal monitors, the main principle of which is to mount 4 groups of probes (each group of probes includes 2 fetal heart rate probes and 1...
