The manual control has high accuracy, the electric speed is uniform, and the combination of the two has the advantage of better simulating delivery.

Description

Technical Field

[0001] The invention relates to the technical field of delivery simulators, and in particular to a transmission device for a delivery simulator. Background Art

[0002] The risk of maternal and newborn death varies significantly between developed and developing countries. The WHO estimates that more than 98% of maternal and infant deaths occur in developing countries. More than half of these deaths occur during home births without the presence of health care providers. However, maternal and infant mortality rates in developing countries are also more than 10 times higher when births take place in health care facilities.

[0003] One of the main reasons for this problem is that there are too few available labor and delivery attendants, and many of these labor and delivery attendants have not been adequately trained to handle obstetric or neonatal emergency cases. The accuracy of the labor and delivery simulation is not high, and the difference from the actual situation is relatively large. Here, the description of the present invention is intended to solve this problem. Summary of the invention

[0004] In view of the above problems, a transmission device for a delivery simulator is proposed according to the present invention, comprising:

[0005] Gear box (1);

[0006] A gear (2) is arranged in a groove on one side of the gear box (1);

[0007] A motor gear (5), the motor gear (5) meshing with the gear (2);

[0008] A worm (8), the worm (8) meshing with the gear (2);

[0009] If the delivery is done manually, the rotation of the gear (2) is controlled by moving the worm (8) up and down;

[0010] If the electric working device is in operation, the motor (3) controls the rotation of the motor gear (5) to control the rotation of the gear (2).

[0011] Preferably, the electric switch of the motor is provided with a speed, and the motor can rotate forward and reverse.

[0012] Preferably, the worm (8) and the roller (11) are connected via two ends of a worm support (9).

[0013] Preferably, one end of the worm support (9) passes through a hole formed by the fixing plate (10) and the gear box (1), and the worm (8) moves up and down through the formed hole.

[0014] Preferably, a slot for fixing the cam is provided on the other side of the gear box (1).

[0015] Preferably, the cam (12) is fixed in the middle of the slot, and the cam (12) is fixedly connected to the cam shaft (6).

[0016] Preferably, the camshaft (6) is in the shape of a letter "7".

[0017] Preferably, a motor (3) is provided on the upper part of the motor gear (5), and the motor (3) is fixed to the gear box (1) via a motor fixing plate (4).

[0018] Preferably, the groove is a circular groove.

[0019] Compared with the prior art, according to the present application, this design is a process in which the baby rotates and moves in the mother's body and finally completes the delivery process. On the same machine, the distance and speed of the baby's forward and backward movement can be controlled manually and electrically. The model has a simple structure, high simulation accuracy and realistic image. The manual control has high accuracy and the electric speed is uniform. The combination of the two can better simulate delivery. The limiting effect of the fixed hole makes the switching between manual and electric smoother, which improves the success rate of manual and electric switching. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Figure 1 Schematic diagram of the structure of the transmission device for the delivery simulator according to an embodiment of the present application, as shown in FIG. Figure 1 As shown. A circular groove is provided on one side of the gear box (1), and a gear fixing frame (7) is placed in the circular groove. A gear 2 is provided on the central axis of the gear fixing frame (7). The gear 2 is meshed with the motor gear 5 and the worm 8 respectively, and a motor 3 is provided on the upper part of the motor gear 5. The motor 3 is fixed to the gear box 1 through the motor fixing plate 4. The worm 8 and the roller 11 are connected through the two ends of the worm bracket 9. One end of the worm bracket passes through the hole formed by the fixing plate 10 and the gear box 1, and the worm 8 can move up and down through the fixing hole. A slot for fixing the cam is provided on the other side of the gear box 1. The cam 12 is fixed in the middle of the slot, and the cam 12 is connected to the camshaft 6. The camshaft 6 is in the shape of a "7".

[0033] When manual delivery is to be performed, the camshaft 6 is twisted by hand so that the protruding end of the cam 12 presses against the roller 11 fixed on the worm bracket 9, the roller 11 rises, the worm bracket 9 slides up, the worm 8 is engaged with the gear 2, and ready, under the action of external force, the worm 8 is twisted to realize manual delivery and the baby moves forward and backward.

[0034] If electric delivery is to be performed, the cam shaft 6 is twisted by hand to make the protruding end of the cam 12 away from the direction of the worm, so that the roller 11 moves downward, the worm bracket 9 slides down, and finally the worm 8 is completely separated from the gear 2. Press the electric switch, the variable speed motor drives the motor gear 6, and the gear 2 meshing with the motor gear is transmitted, so that the baby can move forward and backward and rotate.

[0035] The electric switch is set with the function of speed and forward and reverse rotation of the motor.

[0036] The simulated delivery through the combination of electric and manual methods has the advantages of high simulation accuracy and realistic images.

[0037] Figure 2 Schematic diagram of the structure of the fixing hole of the transmission device for the delivery simulator according to an embodiment of the present application, as shown in FIG. Figure 2 As shown. The fixing hole is composed of a gear box slot 14 and a fixing plate 10, and the fixing plate 10 is fastened to the gear box slot 14. The roller worm 13 passes through the fixing hole. Due to the cam 12 and the fixing hole, the roller moves within a limited range to prevent the roller from moving privately and affecting the manual operation accuracy. The fixing hole may not be composed of the slot 14 and the fixing plate 10, but a separate structure. For example, the fixing hole may also be a cylinder fixed on the gear box 1, or a hollow cube fixed on the gear box 1.
