Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a telescopic prenatal examination chair. Background Art

[0002] Pregnant women should undergo regular prenatal examinations to promote the health of mother and baby. Especially in the third trimester, prenatal examinations are conducted once a week, which is a high frequency and puts a heavy burden on pregnant women and makes their movements inconvenient. During routine prenatal examinations, pregnant women are required to take off their shoes and lie flat. When measuring the abdominal circumference, pregnant women are required to cooperate, lift their waists, put the tape measure into their waists and finally take it out, which is more strenuous for pregnant women in the third trimester and adds difficulty to nursing operations. At the end of the examination, pregnant women are prone to supine hypotension syndrome due to lying flat for a long time, which increases the risk of falling. In addition, pregnant women need to put on and take off their shoes, which is more strenuous, increasing their resistance to prenatal examinations.

[0003] During fetal heart monitoring, pregnant women can lie down or sit, and the operation takes about 20 minutes. Pregnant women usually feel more relaxed and comfortable leaning against the backrest. When pregnant women sit on the chair, the body, backrest and seat cushion form a triangular area. The triangular area is empty relative to the waist of the body. The weight of the pregnant belly depends entirely on the waist and back of the pregnant woman. Sitting for a long time will increase the discomfort of the waist and back of the pregnant woman. Even if some hospitals prepare pillows to fill this triangular area, it is difficult to meet the needs of pregnant women of different heights, weights and thinness.

[0004] A telescopic antenatal examination chair is proposed for this reason. Utility Model Content
