Description

Technical Field

[0001] The present invention relates to medical devices for obstetrics and gynecology, and in particular to a sitting-position delivery chair for doula-assisted childbirth. Background Art

[0002] Childbirth is an important experience in a woman's life. Traditionally, this process is usually carried out on a hospital bed. However, with the progress of medical technology and the promotion of the concept of humanized medicine, more and more parturients choose to use a doula-assisted delivery chair for sitting-position childbirth. The delivery chair allows the parturient to choose a more comfortable posture for childbirth, thereby improving the efficiency and comfort of childbirth. However, the existing delivery chairs still have some deficiencies. On the one hand, their height and angle cannot be adjusted, making it difficult to adapt to the heights and body types of different parturients, and also unable to meet the possible posture changes required by the parturient during childbirth. This may cause discomfort to the parturient during childbirth and even affect the smooth progress of childbirth.

[0003] On the other hand, due to the parturient's fear of childbirth and the discomfort and pain during the childbirth process, family members or midwives are often required to assist in the childbirth work (the purpose is to provide physical support for the parturient, maintain the parturient in a comfortable position; at the same time, it can provide emotional support for the parturient to relieve the tension and anxiety).

[0004] However, the existing doula-assisted delivery chairs are not designed specifically to facilitate the assistance work, resulting in the difficulty for the assistant to provide stable and correct support during the parturient's childbirth. Summary of the Invention

[0005] The object of the present invention is to solve the problems existing in the above background art, and provide a sitting-position delivery chair for doula-assisted childbirth, which can be adjusted in height according to the conditions of different parturients, and at the same time, a special position is designed for family members or midwives to provide stable and correct physical support for the parturient, facilitate soothing the parturient's emotions, and adopt a liquid collection structure that is convenient for installation and disassembly, which can collect the outflow from the perineum of the parturient who gives birth using the doula chair to reduce the pollution caused by the outflow of the discharge.

[0006] In order to achieve the above invention object, the present invention adopts the following technical solutions:
