Technical Field

The invention relates to midwifery equipment, in particular to a obstetric table for semi-sitting position midwifery and a pedal on the obstetric table.

Background

Free position delivery has become a new delivery trend in China at present, namely, a puerpera freely selects comfortable positions (postures such as semi-lying, sitting, lying down, kneeling, squatting, standing, walking and the like) in the delivery process, adopts positions which accord with physiology and can relieve pain or discomfort, and enables the whole body to relax and emotion to be stable with the help of midwife guidance and midwifery tools, thereby promoting natural delivery. Delivery of parturients at different delivery positions requires the use of different delivery tools. Among them, the sitting position joint birth is the more production positions that the puerpera adopts in natural delivery. The sitting position is divided into a semi-sitting position and a sitting position, wherein the lying-in woman sits at the semi-sitting position, the trunk and the bed form an angle of more than 45 degrees, when the lying-in woman adopts the semi-sitting position, the legs and the roots of the legs form a right angle with the bedstead, the knees also bend to form a right angle, and the semi-sitting position can ensure that the fetus in the lying-in woman obtains sufficient oxygen supply and enables the lying-in woman to feel relaxed. The puerpera sits on a bed, a chair, a stool or a delivery ball when sitting. The actual application of the semi-sitting position and sitting position is changed according to the parturient's labor, the parturient's body and the specific condition of the fetus.

At present, the obstetric table for free position delivery in China is imported, and as the height, the body type and the pelvis of Asian women are different from those of women in European and American countries, the distance and the height of each part of the imported obstetric table are generally larger, and the clinical obstetric table cannot meet the demands of free position delivery of most of puerpera in China. There are the following disadvantages:

1. when the semi-sitting position is adopted, the body, legs and feet of the puerpera are difficult to maintain due to the distance problem, so that the physical strength of the puerpera can be consumed, and the labor is affected;

2. when the semi-sitting position or the sitting position is adopted for midwifery, the force application supporting points opposite to the soles are not arranged on the feet of the puerpera, and the puerpera cannot exert force well;

3. the sitting position and the semi-sitting position can cross in the labor process, but the puerpera is not suitable for moving greatly in the labor receiving process, but the current sitting position labor receiving device has no function of facilitating the conversion of the sitting position and the semi-sitting position of the puerpera.

And in the midwifery process, because the force application point of the puerpera is arranged at the bottom of the sole, if the pedal is too hard, the sole of the puerpera is painful, and if the pedal is too soft, the sole position of the puerpera is difficult to fix, so that the posture required by midwifery is difficult to maintain, the physical strength of the puerpera is consumed, and the progress of the puerpera is influenced.
