Positioning device for fetal heart monitor

Abstract

The invention discloses a positioning device for a fetal heart monitor. The device includes a probe rod, and the top of the probe rod is provided with a probe; the bottom of the probe rod is providedwith a negative pressure vacuator, and the negative pressure vacuator is fixedly connected with four fixing supports; the fixing supports are connected with adsorption heads through extension tubes, each extension tube is internally provided with a flexible metal hose, and the surface of each adsorption head is provided with adsorption holes; the negative pressure vacuator is fixedly provided withan exhaust pipe, the side surface of the negative pressure vacuator is provided with a switch, and the interior of the probe is fixedly provided with a vibration sensor; the vibration sensor is connected with an ARM single chip microcomputer through a signal cable, and the ARM single chip microcomputer is connected with a buzzer through a control wire. By arranging the vibration sensor and the buzzer, the position of a fetal heart is looked for more effectively and accurately for a pregnant woman, and by arranging the adsorption heads and the negative pressure vacuator, air pressure is used for fixing the probe which is firm and good in comfort level; the negative pressure vacuator is provided with the switch, so that the probe is convenient to fix and take down.

Description

technical field [0001] The invention relates to the technical field of fetal heart rate monitoring, in particular to a positioning device for a fetal heart rate monitoring instrument. Background technique [0002] The fetal heart rate is the heartbeat of the fetus. The fetal heart rate monitoring examination uses the principle of ultrasound to monitor the situation of the fetus in the uterus. It is the main detection method to correctly evaluate the condition of the fetus in the uterus. The curve of the monitoring graph formed by the signal tracing instantaneous fetal heart rate change can understand the reaction of the fetal heart rate during fetal movement and uterine contraction. The positioning device of the currently used fetal heart rate monitor has the following shortcomings: [0003] (1) When using a fetal heart rate monitor, it is very important to find the position of the fetal heart rate correctly, and the position of the fetal heart rate varies with the change of...

Problems solved by technology

[0003] (1) When using a fetal heart rate monitor, it is very important to find the position of the fetal heart rate correctly, and the position of the fetal heart rate varies with the change of pregnancy. In the past, fetal heart rate monitoring relied on the experience of doctors to find the best position. Position, under the current trend that home fetal heart monitors are entering more and more families, many mothers complain that they are always unable to find the position of the fetal heart rate, which affects the use and sometimes delays the timely monitoring of the fetus;

[0004] (2) The positioning device of the fetal heart rate monitor currently in use is mostly bound to the abdomen of the pregnant woman with an elastic band, or is pasted on the abdomen of the pregnant mother with a one-time adhesive tape. The way is not comfortable, it will leave glue on the pregnant mother's abdomen, and it is not environmentally friendly;

[0005] (3) It is very inconvenient and inefficient to adjust the position of the probe after the probe is fixed on the abdomen of the pregnant mother in the current positioning device of the fetal heart rate monitor.
