Problems solved by technology

Tied the probe on the belly, the pressure is unknown, too much pressure on the belly with the probe will make pregnant women feel oppressed and uncomfortable; in addition, the long-term hand-holding of the probe by the inspector will increase the burden on the inspector and cause the fatigue of the doctor ; And it may cause the probe to move, the fetal heart rate is difficult to find and locate, the signal is unstable, and the detection accuracy is reduced

Embodiment 1

[0036] Such as Figure 1-8 As shown, this embodiment proposes a pressure-adjustable fetal heart monitor, which includes a detection component 3, which is connected to a liquid crystal display 5 through a cable 4, and a tripod 6 is connected to the bottom of the liquid crystal display 5, and a plastic universal support can be selected. , to realize the free positioning and orientation of the liquid crystal display 5 . It also includes arc-shaped slide rails 2, the number of slide rails 2 is set to two, and the two slide rails 2 are connected by connecting rods 16, which can effectively ensure the distance between slide rails 2 and prevent deformation. The detection part 3 comprises a moving seat 32, the outer wall of the moving seat 32 is provided with a micro motor 12, a rubber roller 15, the micro motor 12 is connected with a driving wheel 13, the outer wall of the moving seat 32 is connected with a wheel shaft 11 for rotation, and the wheel shaft 11 is connected with a drive...

Embodiment 2

[0048] Reference attached Figure 9 As shown, the pressure-adjustable fetal heart rate instrument proposed in this embodiment has the same other structures as the first embodiment, the difference is that the slide rail 2 is also provided with a height adjustment mechanism, including a suction cup bracket 7, a suction cup bracket 7 The bottom of the bottom is connected with a suction cup 1, and the suction cup bracket 7 is slidingly connected with the slide rail 2; the suction cup bracket 7 is provided with a number of jacks, and the slide rail 2 is also slidably provided with positioning columns 10 for plugging into the jacks. The positioning column 10 is connected with the support 6 of the slide rail 2 with a spring I9 which plays a reset role.

[0049] In order to pull the positioning post 10 conveniently, a pull ring 8 is connected to the top of the positioning post 10 .

[0050] A suction cup 1 is installed on the slide rail 2, which is convenient for adjustment and fixin...

Abstract

The invention provides a pressure-adjustable fetus-voice meter and a fetus-voice positioning method; the pressure-adjustable fetus-voice meter comprises a detection part and a liquid crystal display;the pressure-adjustable fetus-voice meter also comprises an arc-shaped slide rail, and the detection part comprises a moving seat; a first through cavity is formed in the moving seat, and a sliding sleeve is slidably connected into the first through cavity; the bottom of the sliding sleeve is connected with a probe body, and the top of the sliding sleeve is connected with an upper cover; a secondthrough cavity is formed in one side of the movable seat, an ejector block is slidably arranged in the second through cavity, and oblique teeth inclining downwards are arranged at one end of the ejector block; clamping grooves matched with the oblique teeth are formed in the sliding sleeve; a spring II sleeves the top block, one end of the spring II is connected with the top block, and the other end is connected with the inner wall of the second through cavity; the probe body is provided with a pressure sensor, and six ultrasonic probes are evenly arranged on the outer side of the pressure sensor; a microprocessor for implementing control is also provided. The invention is simple in structure and reasonable in design, the fetal heart can be accurately positioned, meanwhile, the pressure can be conveniently adjusted, and inaccurate detection numerical values caused by excessive force or too small force are prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pressure-adjustable fetal heart rate meter and a fetal heart rate positioning method. 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, and is the main detection method to correctly evaluate the situation of the fetus in the uterus. Fetal heart rate monitoring The fetal heart rate is regulated by the sympathetic and parasympathetic nerves. By tracing the curve of the monitoring graphic formed by the instantaneous fetal heart rate changes, we can understand the fetal heart rate response during fetal movement and uterine contraction, so as to speculate whether there is fetal defect in the uterus. oxygen. Normal fetal heart rate monitoring takes about 20 minutes. High-risk pregnant women should be monitored for ...
