Description

[Detailed explanation of the idea] Industrial applications This invention relates to an improvement of a seated delivery table.

Conventional Techniques Various techniques have been used for childbirth since ancient times, but they are easier for pregnant women to concentrate their childbirth force, and midwives (doctors and nurses) find it easier to perform childbirth than in supine delivery. In recent years, sitting delivery has come to be reconsidered as it allows midwifery to be carried out in a position close to the delivery site. Recently, delivery tables exclusively for sitting delivery have been developed and put into practical use.The configuration of such a delivery table can be summarized as follows: It has a seat board and a back board.
The seat plate is coupled with a thigh-closing prevention part for holding the pregnant woman's thighs open from the inside to the outside, and is equipped with supporting legs for supporting the soles of the pregnant woman's feet. It is characterized by As mentioned above, this delivery table has been well received by pregnant women and midwives, and there are expectations that it will continue to be the mainstream delivery table in the future.

Problems that the invention aims to solve As mentioned above, the seated delivery table has no problems during normal childbirth and promises a smoother delivery than the conventional bed-type delivery table, but the pregnant woman's cervical tract during delivery Occasionally, injuries such as lacerations occur, and in such cases, if the above-mentioned leg closure prevention part is attached to the seat plate,
Since the restraining part becomes an obstacle to treating the above-mentioned diseases, it becomes necessary to move the pregnant woman to another surgical bed.
However, in a time-sensitive situation, it is impossible to transfer the pregnant woman, and the patient has no choice but to remain seated on the delivery table for treatment, but this type of treatment gives the pregnant woman a sense of anxiety and poses safety concerns. However, it contained major problems, and drastic measures were eagerly awaited.

Measures to solve the problem In view of the above circumstances, the applicant separated the restraining part of the above-mentioned seated delivery table in the previous application for utility model registration (filed on July 27, 1989, "Sitting delivery table"). We have proposed a seated delivery table in which the restraining member is made into an independent member and is detachably attached to the seat plate, but the present invention is a further improvement on this, and the above-mentioned restraining member is built into the seat plate. The restraining member is equipped so that it can be moved in and out using a drive means, so that even if an abnormality such as a cervical laceration occurs during childbirth, the restraining member can be immediately stored in the seat board and emergency suturing operations can be performed as is. This is what I did.

To further explain the structure of the present invention in detail based on the accompanying drawings, Fig. 1 is a front view of a seated delivery table in which the present invention is adopted, Fig. 2 is a plan view of the same, Fig. 3 is a right side view of the same,
4 and 5 are a schematic plan view and a vertical sectional view of the tilting device adopted in the present invention. That is, the seated delivery table of the present invention is a seated delivery table A for making a pregnant woman sit or lie down with her legs spread, and has a back plate 2 and a seat plate 3 connected to each other on a base 1. 3 includes a pair of thigh receivers 31, 31 extending in a widened manner with respect to the center of the body of the delivery table A, and an opening 32 formed between the receivers 31, 31; 3
Thigh closure prevention members 4, 4 for holding the pregnant woman's thighs open from the inside to the outside at the distal ends of the thighs 1, 31;
is equipped so as to be freely retractable by means of a driving means 5 built into the seat plate 3, and as shown in the figure, the back plate 2 and the seat plate 3 are independently tiltable on the base 1. The base 1 is raised and lowered by a lifting mechanism (oil cylinder mechanism, motor mechanism, etc.) 10, and the base 1 also has an oil cylinder mechanism for tilting the back plate 2 and seat plate 3. 12 and 13 are built-in. In addition, arm rests for intravenous injection (for intravenous injection) 6, 6 are provided on both sides of the back plate 2 via angle adjustment members (not shown), so that the angle can be adjusted regardless of the angle of the back plate 2. Therefore, it is held substantially horizontally. On the other hand, on both sides of the seat plate 3, there are brackets 7, 7 which project obliquely forward, and at the ends of the brackets 7, 7, support legs 72, 72 for supporting the soles of the pregnant woman's feet are provided with adjustment parts. It is attached via rods 71, 71. The adjustment rods 71, 71 allow the support legs 72, 72 to be adjusted in three dimensions: height, horizontal rotation, and forward/backward tilting. Furthermore, seat plate 3
A tray 8 is installed diagonally below the base 1, and the tray 8 has a storage pocket 81 formed in the base 1.
(See Figure 5).
It is used to receive newborn infants, amniotic fluid, and other excreta during delivery.

In the seat plate 3, which is the main body of this invention,
As shown in FIG. 3, the upper surface is a concave curved surface that roughly follows the shape of the pregnant woman's buttocks and provides a sense of stability, and the opening 32 formed between the thigh supports 31 and 31 is located at the center of the body of the delivery table A. It has a shape and size that is symmetrical to the left and right, opens toward the toes, and has a C-shaped concave curved surface that is convex toward the back plate, so that it does not interfere with taking out the newborn baby diagonally downward. The shape and size of the opening 32 may vary depending on the body shape and physique of the pregnant woman, but the shape and size of the opening 32 should not be an obstacle when removing the newborn from a pregnant woman sitting on the seat plate 3 with her legs apart. It means a shape and size that can be directly taken out onto the tray 8, and a desirable form thereof is shown in the figure. In addition, the thigh closure restraining members 4, 4, which are retractably installed at the tips of the thigh receivers 31, 31, are connected to a driving means 5 of an embodiment described later, and are driven by the action of the driving means 5. It is configured to appear and retract from the tips of the receiving parts 31, 31, but its outer shape is curved outward, that is, with the center of curvature on the thigh side,
It is designed to hold the thigh and prevent it from coming off.

Function When giving birth on the seated delivery table A of the present invention, the pregnant woman is seated on the seat board 3 with her legs spread apart, her thighs are received by the thigh supports 31, 31, and the restraining members 4, 4 to prevent the legs from closing. The pregnant woman's soles are placed on support legs 72, 72, and adjusting rods 71, 71 are adjusted according to the body shape to allow the pregnant woman to take a comfortable posture. Then, tilt the back plate 2 and seat plate 3 appropriately,
The tray 8 is pulled out from the storage pocket 81 of the base 1, and the delivery is performed by making it easier for the pregnant woman to concentrate her childbirth force and for the midwife to perform the midwifery work.
When an abnormality such as cervical laceration occurs during childbirth, the driving means 5 is activated, the restraining members 4, 4 are stored in the seat plate 3, and the back plate 2 and the seat plate 3 are tilted to make the pregnant woman comfortable. Emergency treatment such as suturing surgery is then performed, but in this case, the restraining members 4, 4 do not protrude from the distal ends of the thigh receivers 31, 31, so such surgery, etc. can be performed without any hindrance. I can do it.
