Working principle: This prenatal diagnosis and inspection device for obstetrics clinical use is composed of a bearing plate 7, a seat plate 5 and a back plate 6 to form a variable bed chair. The bed chair has two forms: chair and bed, and the corresponding state can be changed according to the demand. In the initial state, the bed chair is in the chair state. When pregnant women go to the obstetrics department for clinical prenatal diagnosis, they should be placed on the seat plate 5 first, and the slow-release plate on the base shaft 2 is driven by the seat plate 5 under the pregnant woman’s own gravity. The component 3 slides down on the base 1 along the base 1 and squeezes the conversion airbag 4, the conversion airbag 4 deforms under force and fills the right side of the stable self-regulating bag 10 with gas, increasing the air pressure in the right side of the stable self-regulating bag 10, improving Its resistance, and at the same time part of the airflow will flow to the left side of the stable self-adjusting bag 10 to increase the air pressure inside, and then the pregnant woman will use the stable self-adjusting bag 10 through the driven shaft 8 during the process of changing from sitting to lying down The resistance on the back plate 6 gives the back of the pregnant woman a resistance to slow down the speed of lying down, which can effectively improve the stability of the pregnant woman in the process of changing from sitting to lying down, and reduce the physical strength consumed by the pregnant woman in order to lie down.

When you need to get up after the inspection or in the middle, step on the arc-shaped block 161 by applying force on your feet. Press the corresponding stable self-adjusting bag 10 to make it deform and inflate the left side stable self-adjusting bag 10. The linkage assembly 11 drives the bearing plate 7 to rotate upwards, and finally the bed chair becomes a bed from a chair state. During this process, the driven shaft 8 on the left drives the arc block 161 along the bearing plate through the connecting rod 162 7 slides to the right. Therefore, when getting up, step on the arc-shaped block 161 to drive the corresponding driven shaft 8 to perform reset preparatory movement. According to human anatomy, it can be known that the force exerted by the legs of a pregnant woman has an impact on her body safety. It is very small, therefore, it is relatively safe to step back on the arc-shaped block 161 by applying force on the foot. The arc-shaped block 161 drives the corresponding driven shaft 8 to perform a reset movement to a certain extent through the connecting rod 162, that is, the reset preparatory movement. The left driven shaft 8 drives the right driven shaft 8 to move upwards to a certain extent through the reverse linkage assembly 11. Combined with a small amount of control force exerted by the pregnant woman, the up movement is gradually completed. The corresponding amount of gas is filled into the stable self-adjusting bag 10, which determines the resistance strength of the stable self-adjusting bag 10, that is, the heavier the body weight, the greater the resistance, ensuring the stability and safety of the lying down process. In summary, on the basis of improving the stability and safety of pregnant women in the process of sitting and lying up, compared with the existing technology, it not only has a simple structure, low energy consumption, very energy-saving and environmental protection, but also has high flexibility. Responsibility, correspondingly reduces the mechanical loss of the chair bed.

In addition, the right driven shaft 8 drives the conversion sleeve 12 to rotate during the movement, and the conversion sleeve 12 drives the curtain assembly 14 to move through the retractable assembly 13, that is, the curtain is pulled up when the pregnant woman is lying down. , to form a relatively private inspection space. When the inspection is completed, the curtain will be retracted synchronously. On the basis of ensuring the privacy of the inspection process, it can effectively prevent consultation due to forgetting to pull up the curtain during the inspection. The occurrence of adverse psychological effects on pregnant women, and the entire retraction process is carried out automatically and synchronously according to the needs of pregnant women, without the intervention of medical staff, which reduces the workload of medical staff and improves the safety of curtains and chair beds. The interlocking performance perfectly matches the corresponding requirements of the inspection process, which further improves the convenience and practicality of the device.
