Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a delivery ball stand. Background Art

[0002] When pregnant women are expecting delivery or have regular uterine contractions in the late pregnancy, they can sit on the delivery ball and sway their bodies back and forth with the delivery ball, which allows them to independently adjust and choose the best delivery posture, avoid muscle tension, relax the pelvic floor muscles, and relieve the nerve pain in the perineum. In addition, the delivery ball is interesting and can distract pregnant women, effectively improve labor pain for primiparas, shorten the delivery process, and the correct use of the delivery ball can also stabilize the psychological state of pregnant women and reduce postpartum hemorrhage.

[0003] The commonly used fixing devices and methods of use of birthing balls are as follows: 1. Fixing ring: Place the ring-shaped fixing ring on the ground, and place the birthing ball on the fixing ring to prevent the birthing ball from moving; then, under the guidance of the nurse, the pregnant woman grabs a fixed object (such as a bed board) and uses the birthing ball independently. Since the fixing ring only serves to prevent the birthing ball from shaking back and forth, there is no protection on its left and right sides and the back. The birthing ball is spherical and is prone to tilting or even falling due to unstable center of gravity during use. 2. Bracket: It includes two rings arranged up and down, a connecting column arranged between the two rings, and a handle arranged on the back side of the ring. When in use, the birthing ball is also placed on the upper ring. The birthing ball is limited by the upper ring and the handle. The pregnant woman can only squeeze the birthing ball up and down, and cannot shake the birthing ball left and right, which limits the shaking amplitude of the birthing ball, and the hidden danger of tilting still exists. 3. A midwifery chair for relieving pain during childbirth with Chinese patent publication number CN113116673A comprises a base plate, a support plate, a massage backrest and a seat, on which the parturient sits. The above-mentioned midwifery chair also has the problem of restricting the movement of the delivery ball and posing a safety hazard.
