[0002] Fundal height, or simply the height of the uterus, refers to the length from the pubic symphysis in the lower abdomen to the fundus of the uterus. Abdominal circumference refers to the circumference around the abdomen along the navel. Fundal height and abdominal circumference are two important indicators in prenatal checkups. By measuring them, we can understand the development of the fetus and the health of the pregnant woman. In order to provide more accurate, efficient, and personalized measurement results and provide strong support for prenatal care and fetal health monitoring, a precise instrument for measuring fundal height and abdominal circumference is needed.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a precise measuring device for fundal height and abdominal circumference, comprising a base plate 1, a telescopic rod 2 fixedly connected to the upper surface of the base plate 1, a support shell 3 fixedly connected to the outer wall of the telescopic rod 2, a support rod 4 fixedly connected to the inside of the support shell 3, a spring 5 slidably connected to the outer wall of the support rod 4, the outer wall of the spring 5 fixedly connected to the inside of the support shell 3, a connecting block 6 slidably connected to the outer wall of the support rod 4, a fixing block 7 fixedly connected to the upper surface of the connecting block 6, the outer wall of the fixing block 7 slidably connected to the inside of the support shell 3, a connecting rod 8 rotatably connected to the outer wall of the connecting rod 8, a locking block 9 rotatably connected to the outer wall of the connecting rod 8, a slide rail 10 fixedly connected to the inside of the support shell 3, the inside of the locking block 9 slidably connected to the outer wall of the slide rail 10, an abdominal circumference measuring tape box 11 slidably connected to the outer wall of the support shell 3, and the outer wall of the locking block 9 slidably connected to the inside of the support shell 3 and the abdominal circumference measuring tape box 11. A support assembly is provided on the upper surface of the base plate 1 for supporting the pregnant woman.
[0024] Specifically, the abdominal circumference measuring tape box 11 stores a disposable measuring tape. By wrapping the disposable measuring tape around the abdomen along the navel, the abdominal circumference of the pregnant woman can be measured. The use of disposable measuring tape avoids the risk of cross-infection caused by reuse. Pulling the fixing block 7 causes the connecting block 6 to slide on the support rod 4, which in turn compresses the spring 5. The connecting block 6 then pulls the connecting rod 8, which in turn causes the locking block 9 to slide on the slide rail 10. At this time, the locking block 9 will slide out of the abdominal circumference measuring tape box 11, thus achieving the function of quickly replacing the abdominal circumference measuring tape box 11. When installing the abdominal circumference measuring tape box 11, under the rebound of the spring 5, the locking block 9 can firmly fix the abdominal circumference measuring tape box 11.
[0025] Reference Figure 1 The support assembly includes a base 12, the lower surface of which is fixedly connected to the upper surface of the base plate 1, and a medical bed 13 is fixedly connected to the upper surface of the base 12.
[0026] Specifically, the base 12 serves to support and fix the medical bed 13, which in turn supports the pregnant woman.
[0027] Reference Figure 1 and Figure 3 A support frame 14 is fixedly connected to the upper surface of the base plate 1. A motor 15 is fixedly connected inside the support frame 14. A connecting column 16 is fixedly installed at the output end of the motor 15. The outer wall of the connecting column 16 is rotatably connected to the inside of the support frame 14. A first bevel gear 17 is fixedly connected to the outer wall of the connecting column 16. A second bevel gear 18 is meshed with the tooth end of the first bevel gear 17. The outer wall of the second bevel gear 18 is rotatably connected to the inside of the support frame 14. A threaded rod 19 is fixedly connected inside the second bevel gear 18. A connecting plate 20 is threadedly connected to the outer wall of the threaded rod 19. A support frame 21 is fixedly connected to the outer wall of the connecting plate 20. An infrared ranging probe 22 is fixedly connected to the lower surface of the support frame 21.
[0028] Specifically, the motor 15 drives the connecting column 16 to rotate within the support frame 14. The connecting column 16 then drives the first bevel gear 17 to rotate, which in turn drives the second bevel gear 18 to rotate within the support frame 14. The second bevel gear 18 then drives the threaded rod 19 to rotate. With the connection of the connecting plate 20, the height of the support frame 21 can be adjusted. With the help of the infrared ranging probe 22, the fundal height of the pregnant woman can be accurately measured. The infrared ranging probe 22 utilizes the scattering phenomenon of objects within the infrared spectrum to emit monochromatic light and receive the reflected monochromatic light. Through circuit processing, the corresponding stress signal is obtained, thereby calculating the distance to the target object, ensuring the accuracy and reliability of the measurement.
[0029] Working principle: When the measuring device is needed, first, have the pregnant woman lie flat on the medical bed 13. Then, take out the disposable measuring tape from the abdominal circumference measuring tape box 11 and measure the pregnant woman's abdominal circumference. When the disposable measuring tape in the abdominal circumference measuring tape box 11 is used up, simply pull the fixing block 7 to make it slide in the support shell 3. The fixing block 7 drives the connecting block 6 to slide on the support rod 4. At this time, the spring 5 will be squeezed. The connecting block 6 pulls the connecting rod 8, which in turn drives the locking block 9 to slide on the slide rail 10. At this time, the locking block 9 will slide out of the abdominal circumference measuring tape box 11, so that the abdominal circumference measuring tape box 11 can be quickly replaced. With the support of the telescopic rod 2, the measurement is more convenient and efficient. The motor 15 drives the connecting column 16 to rotate in the support frame 14. The connecting column 16 drives the first cone The rotation of gear 17 drives the second bevel gear 18 to rotate within the support frame 14. The second bevel gear 18 then drives the threaded rod 19 to rotate. With the connection of the connecting plate 20, the height of the adjustable support frame 21 can be adjusted. Under the action of the infrared ranging probe 22, the fundal height of the pregnant woman can be accurately measured. This measuring device not only achieves the effect of quickly changing the abdominal circumference measuring tape box 11, allowing medical staff to easily change the abdominal circumference measuring tape box 11 after use without interrupting the measurement process, thus saving time and improving work efficiency, but also achieves the effect of adjusting the height of the infrared ranging probe 22 as needed. This allows medical staff to quickly adjust the height of the probe according to the different body shapes and needs of pregnant women, ensuring the accuracy of the measurement and reducing the time wasted due to repeated adjustments.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
