Description

Special mattress and bed device suitable for pregnant woman

Technical Field

The invention relates to the technical field of medical equipment, in particular to a special mattress and a bed device suitable for pregnant women.

Background

It is known that a woman has obvious bulging of the stomach after four months of pregnancy, and the pregnant woman is a special physiological period needing nutrition enhancement during pregnancy, because all nutrients needed by the growth and development of a fetus come from a mother, and the pregnant woman needs to store nutrients for delivery and milk secretion, so that the maintenance of the nutritional status of the pregnant woman during pregnancy plays an important role in the pregnancy process and the development of the fetus and the baby. Meanwhile, the physical and mental satisfaction of the pregnant woman during pregnancy is very important, and the physical and mental health of the pregnant woman can influence the physical and mental health of a child in the first time, so that the improvement of the physical and mental health of the pregnant woman is very important.

After research studies, it was found that pregnant women beset them during pregnancy mainly two needs: amount of exercise and quality of sleep. Because the children grow up in the abdomen, the pregnant woman can not have enough exercise capacity to keep healthy like normal people, most of the time is spent on the bed, and simultaneously, the sleeping posture can not be randomly changed like normal people when the pregnant woman sleeps on the bed, so that the cervical spondylosis caused by the fact that the pregnant woman sleeps in the same posture for a long time is often caused to a certain extent. Therefore, it is necessary to invent a mattress and a bed device for improving the sleeping quality of pregnant women to help the pregnant women improve the sleeping quality and improve the amount of exercise.

Retrieval of patent publication No.: CN103945737B discloses a mattress in which a plurality of holes having a straight portion inclined at an angle with respect to the width direction of the mattress are formed at predetermined intervals in the thickness direction of the leg portions of the mattress, and the plurality of holes are arranged in a zigzag shape in plan view on the mattress, and a bed apparatus using the mattress. The device can apply shear stress to the through-hole of mattress and make it shrink easily high-efficiently, though bearing capacity increases, is difficult to warp, but comparatively popular, does not have pertinence, and to the longer patient of gestational period, it is inconvenient to use. Its patent publication no: CN109619906A, discloses a household pneumatic pregnant woman bedding, wherein an upper and a lower movably detachable combined mattresses are arranged in one side of a pregnant woman, and a combined pneumatic lifting support pad is arranged on one mattress; the combined pneumatic lifting support cushion comprises a waist support at the middle part and heightened lateral position waist supports at the left side and the right side, and the waist support and the lateral position waist supports are communicated with an electric control valve through an airtight pipeline arranged in the combined mattress. The device overcomes the technical problems that the traditional bedding has complex structure and high noise and the whole bed group needs to be replaced. But the device only improves the sleep quality of the pregnant woman, does not relate to the aspect of exercise amount, and has complex operation and higher cost, thereby being not beneficial to popularization and use. In view of the above, there is a need to design a mattress and a bed device for improving the sleeping quality of pregnant women and helping to improve the exercise capacity of pregnant women, and no report is found about the novel mattress and bed device.
