Description

Technical Field

[0001] The utility model relates to the technical field of fetal heart monitors, in particular to a light and thin fetal heart monitor. Background Art

[0002] A fetal heart rate monitor is a device used to detect the heart rate of the fetus. It is a must-check item during obstetric checkups in the late pregnancy. The fetal heart rate monitor used in obstetric checkups is a relatively large device, which is not convenient for mothers to use at home. In order to meet the needs of mothers for daily use, the patent number is CN 215937457U, and the patent name is: A handheld rechargeable Doppler fetal heart rate monitor. This type of fetal heart rate monitor uses a screen holder to place the display screen, which will inevitably increase the thickness and has the disadvantage of being bulky and inconvenient for users to hold.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a light and thin fetal heart rate monitor, reduce the thickness of the fetal heart rate monitor, and facilitate hand-held use.

[0006] By welding the screen directly to the mainboard, the screen holder and the supporting parts for the screen holder and the mainboard can be removed, which can effectively reduce the thickness, and then reduce the thickness of the host, making it easier to use it in hand. By setting a screen enclosure on the inner side of the face shell, it has the same effect as the screen holder, and limits the position of the display screen.

[0007] Furthermore, the mainboard is provided with a first screw hole, and the inner side of the cover is provided with a second screw hole, and the first screw hole matches with the second screw hole. The mainboard can be installed on the inner side of the panel by passing the screw through the first screw hole and the second screw hole.

[0008] Furthermore, the front shell is provided with a positioning column, the mainboard is provided with a first positioning hole, and the rear shell is provided with a second positioning hole, and the positioning column cooperates with the first positioning hole and the second positioning hole. The positioning column is inserted into the first positioning hole, so that the mainboard and the front shell can be quickly pre-fixed, and the screws can be conveniently inserted into the first screw hole and the second screw hole. The positioning column is further inserted into the second positioning hole, so that the front shell and the rear shell can be pre-fixed, which is convenient for connecting the front shell and the rear shell, and the mainboard can also be limited.

[0009] Furthermore, the thin and light fetal heart rate monitor also includes: a protective panel covering the screen window.

[0010] Furthermore, the thin and light fetal heart rate monitor further includes: a side mounting frame, the side mounting frame is connected to the front shell and the rear shell, and the Doppler ultrasound probe is placed on the side mounting frame.

[0011] Furthermore, the front shell and the rear shell are connected via a snap connection.

[0012] Furthermore, the front shell is provided with a third screw hole, the rear shell is provided with a fourth screw hole, and the third screw hole cooperates with the fourth screw hole.

[0013] By adopting the above scheme, the utility model provides a lightweight fetal heart rate monitor, which reduces the screen seat by directly welding the display screen to the main board and arranging a screen enclosure on the inner side of the face shell, that is, the thickness can be effectively reduced, and the thickness of the host can be made thinner, so that the user can use it by hand conveniently.
