Description

Technical Field

[0001] The utility model relates to the technical field of midwifery, in particular to a midwifery device. Background Art

[0002] Obstetrics and gynecology is one of the four major disciplines in clinical medicine. Midwifery refers to a series of measures taken before and during delivery to ensure the smooth delivery of the fetus through the mother's birth canal. When midwives are performing their midwifery duties during delivery, in order to facilitate the smooth delivery of the fetus, they need to use midwifery equipment to assist in suctioning the fetal head. Fetal head suction is to place the outer port of the suction device on the exposed fetal head, and then use a syringe to suck out the air in the suction device to form a negative pressure area. The principle of negative pressure suction is used to suck the fetal head, and the fetal head is delivered in coordination with uterine contractions.

[0003] The Chinese patent with announcement number CN218943472U discloses an obstetric device, including a box body and a cylindrical shell, an air suction pump is installed inside the box body, a support column is fixed on the top of the box body, a positioning column is fixed on the top of the support column, a positioning hole is opened on the cylindrical shell, the positioning column is movably sleeved in the positioning hole, a rotating motor is installed inside the cylindrical shell, a rotating shaft is fixed to the output shaft of the rotating motor, the rotating shaft is rotatably sleeved in the cylindrical shell, a suction disk is hinged at one end of the rotating shaft, a push rod motor is hingedly connected between the rotating shaft and the suction disk, a diverter plate is fixed inside the suction disk, the diverter plate is provided with suction holes arranged in a circumferential array, the suction disk is connected to the air inlet of the suction pump through a hose, and a silicone ring is fixed to the port of the suction disk.

[0004] Although the above-mentioned midwifery device is easy to operate, convenient for midwifery operations, and flexible to use, in actual use, since the suction disc is tightly attracted to the fetal head, mucus from the fetal head will adhere to the suction disc, so it needs to be cleaned after use. The suction disc of the above-mentioned midwifery device is fixed on the device, which is inconvenient to disassemble and clean, so further improvements are needed. Utility Model Content
