Fetal heart and fetal movement are routine means to check whether the fetus is developing normally. The normal fetal heart rate changes with the difference of the intrauterine environment at any moment, and the change of the fetal heart rate is the representation of the good state or not of the baby in the uterus.
Through the monitoring to fetal heart fetal movement, can in time know the condition of pregnant woman's fetus in the abdomen, in time take the pertinence measure, prevent that the fetus from appearing unusually. The monitoring of fetal heart and fetal movement is widely applied to clinic and is an indispensable important link for realizing good prenatal and postnatal care.
The fetal heart monitor device has higher requirements on the aspects of accuracy, reliability, convenience and the like.
At present, most hospitals adopt wired probes for monitoring, fetal heart sounds and uterine contraction signals are collected through the probes, and the wireless fetal heart monitoring system has the advantages of high reliability, large volume, inconvenience in carrying and incapability of completing fetal heart monitoring in real time. The household fetal heart monitor can conveniently monitor fetal heart, is small and exquisite in structure, convenient to carry and more extensive in application. However, when the fetal heart monitor is used, the probe is required to be coated with the couplant, and the couplant is mainly extruded from the couplant bottle in the prior art, so that the fetal heart monitor is inconvenient to carry, cannot control the dosage of the couplant, affects the accuracy of measurement and causes waste.
Chinese utility model with patent number CN201520283133.4 discloses a medical ultrasonic couplant device, which realizes convenient smearing of couplant by embedding a ball smearing head at one end of the couplant device. However, in the using process, as the position of the fetus in the abdomen is changed at any time, the couplant spraying is required to be carried out continuously, the use of the probe and the couplant device is required to be switched continuously, the time and the labor are consumed, the use is inconvenient, the problem that the dosage of the couplant is controlled is not considered in the design, and the problem that the uniformity of the couplant coating is not considered.
The Chinese invention with the patent number of CN201811243482.8 discloses a household fetal heart detection ultrasonic probe with a couplant smearing head, wherein the couplant smearing head is integrated on the ultrasonic probe, so that the detection procedure is simplified, and the problem of uniform smearing of the couplant is solved. However, when the device is used, a control switch is needed to control the opening and closing of the closed cover of the accommodating cavity, the requirements on the reliability and safety of the mechanism are high, the cost is also high, the dosage of the couplant cannot be effectively controlled, an interface is needed for supplementing the couplant and is connected with a couplant bottle, the structural reliability is insufficient, and the use is inconvenient. There is no concern about compatibility issues with portability and use.
The Chinese invention with the patent number of CN201811353408.1 discloses a couplant smearing head detachably connected with a household fetal heart detection ultrasonic probe, the couplant smearing head is uniformly smeared in a mode of integrating the couplant smearing head on the ultrasonic probe, convenient replacement is realized through the detachable smearing head, the compatibility is higher, but the dosage control of the couplant and the couplant supplement mode are still similar to those of the Chinese invention with the patent number of CN201811243482.8, and more problems exist.
