Description

Technical Field

[0001] The utility model relates to the technical field of delivery chairs, in particular to a delivery chair for obstetrics and gynecology. Background Art

[0002] The origin of the birthing chair can be traced back to the development of midwifery in ancient times. In ancient times, midwifery was performed by midwives or similar professionals who used various tools and equipment to help pregnant women give birth smoothly, and the birthing chair was one of the tools.

[0003] In general, the origins of the birthing chair can be traced back to the development of ancient midwifery techniques. It is a tool designed to provide a better midwifery environment and comfort. Over time, the design and function of the birthing chair have continued to evolve and improve to meet the needs of the modern delivery process.

[0004] The publication number CN 213490212U discloses a maternity chair for obstetrics and gynecology, including a base, a fixed seat, a sliding support column, a fixed column, a seat, a backrest, a driving device, and a transmission device. The driving device includes an ear block, a hinge rod, a hinge seat, a moving block, and a mounting seat. The transmission device includes a screw, a screw nut, and a motor. The utility model provides a maternity chair composed of a seat and a backrest. The parturient waits for delivery on the maternity chair, which is convenient for medical staff to observe. At the same time, a driving device is provided. The motor in the transmission device drives the screw to rotate, so that the two screw nuts move relative to each other, driving the moving block in the driving device to move relative to each other, and then the hinge rod rotates along the hinged part with the ear block, driving the seat to rise and fall, which is convenient for medical staff to observe, and does not require the parturient to raise her body too high, reducing the fatigue of the parturient.

[0005] The obstetrics and gynecology delivery chair is convenient for medical staff to observe, and does not require the parturient to raise her body too high, thereby reducing the parturient's fatigue. Since the device is provided with a base for overall support, it cannot be moved and needs to be carried manually when in use. Therefore, when using the device, it is not easy for the user to move the device. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model provides a universal wheel, and the user can push the device to move, so that the universal wheel moves. When it moves to a suitable position, the motor can be started to drive the screw rod at the output end to rotate. At this time, the support block can move up and down and contact the ground to fix the device above, so that the universal wheel no longer moves, thereby achieving the technical effect of fixing the entire device, and the device can be used more conveniently. The user can sit on the base, place both hands on the armrests, and lean back to contact the backrest. The user can turn the rotating handle so that the rotating handle rotates together with the connecting block, driving the second gear to rotate and mesh with the first gear. At this time, the rotating shaft rotates with the rotating handle. Since the upper surface of the connecting block is fixedly connected to the rotating handle, when the rotating handle is turned, the angle of the backrest can be adjusted, so that the user can lean on the backrest more comfortably. When the backrest is subjected to force, the first gear does not rotate, but meshes with the second gear to provide support for the backrest, and the angle will not change downward due to weight.

[0020] The utility model provides a placement bracket, and the user can pull the handle below the placement bracket to make the sliding shaft slide on the inner wall of the fixed block, and when the sliding shaft is pulled out to a suitable position, the leg can be placed above the placement bracket.
