A fetal monitor with adjustable pressure

Technical Field

The utility model relates to the technical field of fetal heart monitors, in particular to a fetal heart monitor with adjustable pressure.

Background Art

Doppler fetal heart rate monitors are mainly used for fetal heart rate monitoring. Generally, obstetrics and gynecology hospitals provide fetal heart rate monitoring. These fetal heart rate monitors use ultrasonic Doppler technology, so they are also called Doppler fetal heart rate monitors. Ultrasonic diagnosis based on the Doppler effect is also called Doppler ultrasound diagnostic instrument D-type ultrasound diagnostic instrument. It is used in medical clinical diagnosis for the diagnosis of heart, blood vessels, blood flow and fetal heart rate.

At present, in the prior art, a Chinese patent with announcement number CN218128586U discloses a fetal heart monitor with adjustable pressure. The device is provided with a fetal heart monitor, a connecting line, a detection head, an adjustment mechanism and a stretching line. By pulling the stretching line, the detection head is pulled to reduce the pressure of the detection head on the abdomen of the pregnant woman, thereby improving the experience of the pregnant woman. However, the force of pulling the pull rope in the device is not well controlled, and the detection head is easily pulled away from the abdomen of the pregnant woman, resulting in inaccurate monitoring effect. In view of this, we propose a fetal monitor with adjustable pressure.

The utility model provides a fetal monitor with adjustable pressure, which has the following beneficial effects:

(1) In the fetal monitor with adjustable pressure, when the belt is too tight, the belt is pulled to stretch it, thereby reducing the pressure of the probe on the abdomen. When the belt is too loose, the sliding rod is pulled to retract the belt through the coil spring. The pressure of the probe on the pregnant woman's abdomen is adjusted by adjusting the tightness of the belt. This adjustment method allows the probe to always be in the pregnant woman's abdomen, thereby improving the accuracy of monitoring.

(2) When the belt clip of the fetal monitor with adjustable pressure is inserted into the clamping device, the belt clip can be fixed by inserting it into the clamping slot. When it needs to be separated, the pressing head is pressed down and the belt clip is pulled out to complete the separation. This installation and disassembly operation is simple and convenient, and can be quickly fixed and separated on the abdomen of a pregnant woman.

The utility model proposes a fetal monitor with adjustable pressure, including a monitor body 1, the monitor body 1 is hinged with a cover body 5, a placement seat 2 is provided above the monitor body 1, a probe 3 is provided above the placement seat 2, and a belt device 4 is fixedly connected to the top of the probe 3. The belt device 4 includes an adjustment device 42, the adjustment device 42 is provided with a slide groove 425; a belt clamp 41, the belt clamp 41 is slidably connected to the inner wall of the adjustment device 42; and a clamping device 43, the clamping device 43 is clamped and connected to the belt clamp 41.

In the embodiment of the utility model, in order to bind the probe 3 to the abdomen, specifically, the clamping device 43 is provided with a sliding groove 431, the sliding groove 431 is slidably connected with a clamping rod 433, the top of the clamping rod 433 is fixedly connected with a pressing head 434, the bottom of the clamping rod 433 is fixedly connected with a spring 2 432, the end of the spring 2 432 away from the clamping rod 433 is fixedly connected to the inner wall of the sliding groove 431, and the clamping rod 433 is provided with a clamping groove 4331. When the guard belt clamping head 41 extends into the clamping device 43, the guard belt clamping head 41 contacts and squeezes the clamping rod 433. When the card rod 433 is squeezed, the card rod 433 slides downward inside the sliding groove 431 and squeezes the spring 2 432, causing the spring 2 432 to undergo elastic deformation. When the belt clip 41 hits the inner wall of the card rod 433, the pressure on the card rod 433 disappears. At this time, the card rod 433 is pushed out under the elastic force of the spring 2 432, and the belt clip 41 is clamped into the card groove 4331 to complete the fixation. When it needs to be disassembled, the pressing head 434 is pressed down to make the card rod 433 slide inside the sliding groove 431. When it slides to the bottom, the belt clip 41 is pulled out to complete the separation.

In the embodiment of the utility model, in order to be able to adjust the pressure of the probe 3 on the abdomen, the adjusting device 42 includes a tape roller 421, the outer wall of the tape roller 421 is fixedly connected to a ratchet 422, the ratchet 422 is rotatably connected to the inner wall of the adjusting device 42, the adjusting device 42 includes a tape roller 421, the outer wall of the tape roller 421 is fixedly connected to a ratchet 422, the ratchet 422 is rotatably connected to the inner wall of the adjusting device 42, the end of the tape roller 421 away from the ratchet 422 is fixedly connected to a coil spring 423, the outer wall of the coil spring 423 is connected to the adjusting device 42 is fixedly connected to the inner wall of the adjusting device 42, the adjusting device 42 includes a control device 424, the control device 424 includes a block 4243, the block 4243 is meshed with the ratchet 422, the outer wall of the block 4243 is fixedly connected to a slide rod 4244, the slide rod 4244 is slidably connected to the slide groove 425, the outer wall of the block 4243 is fixedly connected to a spring 4242, the end of the spring 4242 away from the block 4243 is fixedly connected to the inner wall of the support slide 4241, the support slide 4241 is fixedly connected to the inner wall of the adjusting device 42, and the support slide 4 The inner wall of 241 is slidably connected with the card block 4243, and the outer wall of the card block 4243 is provided with a card block 4243. The belt guard card head 41 is pulled to rotate the belt roller 421. When the belt roller 421 rotates, the ratchet 422 rotates and the coil spring 423 is elastically deformed. When the ratchet 422 rotates, the card block 4243 is squeezed and slides on the inner wall of the support slide 4241. When the card block 4243 slides, the spring 4242 is squeezed and elastically deformed. When the teeth on the ratchet 422 rotate over the card block 4243, the card block 4 243 pops out under the elastic force of spring 4242 and gets stuck in the tooth groove to complete the one-way limiting of the ratchet 422. When it is necessary to retract the protective belt, pull the slide bar 4244 to make the block 4243 disengage from the ratchet 422. At this time, the belt roller 421 rotates under the action of the winding spring 423 to retract the protective belt. When the protective belt is too tight, pull the protective belt to stretch it. When the protective belt is too long, pull the slide bar 4244 and retract the protective belt through the winding spring 423. The pressure of the probe 3 on the pregnant woman's abdomen is adjusted by the tightness of the protective belt.

In the utility model, when in use, first start the power supply, open the monitor body 1, place the probe 3 on the pregnant woman's abdomen, pull the belt clamp 41 to fix the probe 3 on the pregnant woman's abdomen, and when the detection is completed, press the button 434 to separate the belt clamp 41 from the clamping device 43, and then pull the slide bar 4244, and the belt roller 421 is rotated by the action of the winding spring 423 to recycle the belt.
