Description

Technical Field

[0001] The utility model relates to the technical field of obstetric midwifery equipment, in particular to a free-position delivery stool. Background Art

[0002] The traditional delivery method is supine delivery. This delivery method has the disadvantages of easily leading to insufficient blood supply to the placenta and ineffective use of abdominal pressure, which can lead to prolonged labor, fatigue, abnormal fetal heart rate and bleeding. Therefore, if the mother's condition allows, it is preferred to use a delivery stool for sitting and standing and kneeling delivery. Sitting and standing delivery and kneeling delivery simulate the toilet defecation mode. The fetus can increase the pelvic width by 3-5mm under the action of gravity, which is more conducive to the use of abdominal pressure by the mother, facilitates the descent of the fetal head, promotes the progress of labor, shortens the second stage of labor, and reduces the occurrence of dystocia and shoulder dystocia to a certain extent.

[0003] The existing delivery stool is mainly suitable for sit-up delivery of small pregnant women. It is not suitable for prone and kneeling delivery. During prone and kneeling delivery, the chair back cannot support the arms and elbows of the mother well, and the pregnant woman cannot cooperate well in exerting force. For this reason, we propose a free-position delivery stool. Utility Model Content

[0024] The above and other technical features and advantages of the utility model are further described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only preferred embodiments of the utility model, not all of them.

[0025] Example:

[0026] like Figure 1-5 As shown, the utility model provides a free-position delivery stool, comprising a seat frame 1, a cushion plate 2 installed on the top of the seat frame 1, a backrest plate 3 installed on the side of the seat frame 1, an adjustment slide 4 is opened inside the backrest plate 3, a flexible support plate limiting assembly 5 is installed between the adjustment slides 4, two groups of extension rods 6 are sleeved inside the flexible support plate limiting assembly 5, and a flexible support plate 7 is installed between the ends of the two groups of extension rods 6;

[0027] The flexible support plate limiting assembly 5 drives the flexible support plate 7 to move along the surface of the backrest plate 3 through the extension rod 6, and adjusts the setting position of the flexible support plate 7 on the backrest plate 3. The flexible support plate 7 provides different support heights, and the flexible support plate 7 is flipped to provide lying support.

[0028] The flexible support plate limiting assembly 5 includes a sliding connecting plate 51, a positioning knob 52 and an extension rod sleeve 53. The sliding connecting plate 51 is a U-shaped structure. Both ends of the sliding connecting plate 51 are sleeved in the adjusting slide groove 4. The positioning knob 52 is connected to the middle part of the sliding connecting plate 51. The extension rod sleeve 53 is opened in both ends of the sliding connecting plate 51. The extension rod member 6 is sleeved in the extension rod sleeve 53. The two ends of the sliding connecting plate 51 respectively contact with the inner wall of the adjusting slide groove 4. The sliding connecting plate 51 is fixed in the adjusting slide groove 4 by the friction force generated by the contact. The friction force between the sliding connecting plate 51 and the adjusting slide groove 4 can make the sliding connecting plate 51 initially fixed at the required position in the adjusting slide groove 4, which is convenient for the initial adjustment of the position of the sliding connecting plate 51. The length of the two ends of the sliding connecting plate 51 is less than the length of the adjusting slide groove 4, and the sliding connecting plate 51 is completely retracted in the adjusting slide groove 4.

[0029] The end of the positioning knob 52 is provided with stripes for increasing friction, and the end of the positioning knob 52 contacts the side wall of the seat frame 1. In the process of rotating the positioning knob 52, the positioning knob 52 drives the extension rod 6 and the flexible support plate 7 to move horizontally and closely against the surface of the backrest board 3 through the threaded connection, thereby completing the further position limitation of the setting position of the flexible support plate 7, so that the flexible support plate 7 is fixed at the corresponding height position of the backrest board 3, providing the corresponding lumbar and sacral support capacity for pregnant women of different body shapes.

[0030] The extension rod 6 includes a sliding rod 61, a rotating rod 62 and a limit knob 63. The sliding rod 61 is sleeved in the extension rod sleeve 53. The rotating rod 62 is connected to the end of the sliding rod 61 through a rotating shaft. The limit knob 63 is connected to one end of the extension rod sleeve 53. The limit knob 63 passes through the outer wall of the sliding connecting plate 51 and contacts the extension rod sleeve 53. When it is necessary to adjust the flexible supporting plate 7 from a vertical state to a horizontal state, the limit knob 63 is first rotated to release the squeezing limit on the sliding rod 61. The rotating rod 62 can be pulled horizontally to make the rotating rod 62 and the sliding rod 61 move horizontally along the extension rod sleeve 53. After the connection between the rotating rod 62 and the sliding rod 61 is moved out of the extension rod sleeve 53, the rotating rod 62 can rotate around the sliding rod 61.

[0031] The connection between the sliding rod 61 and the rotating rod 62 is a semi-open design that is open upward. The movable angle of the rotating rod 62 through the rotating shaft in the sliding rod 61 is 0 to 90 degrees. After the connection between the sliding rod 61 and the rotating rod 62 extends from the inside of the extension rod sleeve 53, the rotating rod 62 can rotate upward around the sliding rod 61. During the rotation of the rotating rod 62, the flexible supporting plate 7 connected to the rotating rod 62 changes from a vertical state suitable for sitting delivery to a horizontal state suitable for kneeling delivery.

[0032] The side where the flexible support plate 7 is connected to the extension rod 6 is designed to be arc-shaped to match the backrest plate 3. The arc-shaped portion of the flexible support plate 7 can fully contact the backrest plate 3. The backrest plate 3 provides stable support for the flexible support plate 7, so that the flexible support plate 7 can be stably arranged on the surface of the backrest plate 3.

[0033] The other side of the flexible support plate 7 is designed to be flat. In the vertical state, the flat support surface can effectively support the lumbar sacrum of the pregnant woman. After the flexible support plate 7 is rotated to the horizontal state, the flexible support plate 7 can provide a stable and straight arm and elbow support surface to support the arms and elbows of the pregnant woman.

[0034] A set of side grips 8 are provided on both sides of the seat frame 1. The side grips 8 cooperate with the seat cushion board 2 and the backrest board 3 to form a lying area for pregnant women. When the pregnant woman adopts a sitting delivery posture, the side grips 8 can be used for the pregnant woman to hold on to, which is convenient for the pregnant woman to exert force. When the pregnant woman adopts a lying kneeling posture, the side grips 8 can limit the pregnant woman's legs from sliding outward from the surface of the seat cushion board 2, preventing the pregnant woman from tipping to one side, thereby ensuring the normal delivery process of the pregnant woman.

[0035] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
