A kind of multi-point fetal heart rate monitor

Abstract

The invention discloses a multipoint fetal heart monitoring instrument. A power source module, a main control module and a probe module are arranged in a shell. The probe module comprises a fixing frame, a main ultrasonic sensor, a rotating frame, an auxiliary ultrasonic sensor, a transmission gear, a reduction gear and a stirring gear; the main ultrasonic sensor is fixedly arranged at the lower end of the fixing frame, a rotating shaft which penetrates through a shielding plate and is fixedly connected with an upper shell is arranged at the upper end of the fixing frame, and is rotationally sleeved with the rotating frame through a bearing, the auxiliary ultrasonic sensor is installed on the side of the rotating frame, the transmission gear is fixedly connected on the rotating frame, the reduction gear is arranged in the shell through a gear shaft, and the stirring gear is arranged on the side of the shell through a gear shaft. By means of the multipoint fetal heart monitoring instrument, the fetal heart can be rapidly sought and positioned; the position of the auxiliary ultrasonic sensor is adjusted, and the signal strength of fetal heart monitoring is reinforced and kept stable, and the accuracy of the monitoring result is guaranteed.

Description

technical field [0001] The invention relates to the technical field of household fetal heart rate monitors, in particular to a multi-point fetal heart rate monitor. Background technique [0002] Fetal heart monitor is an instrument used to monitor fetal heart rate, usually divided into two types: medical and household. By monitoring the fetal heart rate, we can understand the reaction of the fetal heart rate during fetal movement and uterine contraction, so as to speculate whether the fetus is hypoxic in the uterus. The normal fetal heart rate is 110-160 beats / min. Times / minutes all indicate fetal intrauterine hypoxia and should be treated in time. [0003] Household fetal heart rate monitors use the principle of ultrasonic detection to monitor fetal heart rate. For example, a fetal heart rate monitor disclosed in patent announcement number CN203914959U includes an ultrasonic probe, a data analysis component and an intelligent terminal. For the returned ultrasonic chip, fi...

Problems solved by technology

[0004] The common problems of existing household fetal heart rate monitors are: it is difficult to find and locate the fetal heart rate, and the fetal heart rate signal strength is unstable during the monitoring process, resulting in inaccurate monitoring results; in addition, most of the existing fetal heart rate monitors use a handle structure, Not good for pregnant women to use alone
