Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a leg lifting and expansion device for pregnant women. Background Art

[0002] Women need to undergo corresponding examinations before pregnancy and in the early stages of pregnancy. The examination items include leucorrhea examination. The leucorrhea examination requires women to lie on the bed with their legs raised and open. At this time, the women's legs are suspended in the air, and it is quite strenuous for pregnant women to keep their legs suspended in the air for a long time.

[0003] Therefore, after searching, a leg lifting and expansion device for obstetrics and gynecology with publication number CN114587906A is found. When taking out leucorrhea, the patient lies on the bed and pushes the device to the right side of the bed so that the arc-shaped plate is opposite to the knee joints of the woman's legs. The sliding frame moves upward to push the rotating plate, the rotating shaft and the arc-shaped plate to move upward. The arc-shaped plate moves upward to lift the woman's legs; the rotating plate rotates upward to drive the right-angle plate, the guide rod, the sliding sleeve, the connecting plate and the sliding plate to move upward. After the sliding plate moves upward to the point where it can no longer move upward, the connecting plate rotates outward and opens. The connecting plate rotates outward and opens through the sliding sleeve, the guide rod and the right-angle plate, and during this process, the guide rod moves in the sliding sleeve, and the rotating plate rotates outward and opens, driving the rotating shaft and the arc-shaped plate to rotate outward and open. The arc-shaped plate rotates outward and opens to open so that the woman's legs can be opened.

[0004] However, during the rotation of the connecting plate, the sliding sleeve at one end of the connecting plate will rise, thereby causing the guide rod and the right-angle plate to rise. Therefore, after the height of the rotating plate is fixed, when the connecting plate is rotated to open the legs, the height of the rotating plate will increase an additional distance, causing the height of the pregnant woman's legs to be lifted beyond the expected value, which can easily cause discomfort to the pregnant woman.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following is combined with Figure 1-4 The utility model is further described.

[0023] In order to solve the technical problems in the background technology, the present application provides: a leg lifting and expansion device for pregnant women, including a mounting plate 1. When in use, the mounting plate 1 is fixed at the end of the bed, and when the patient lies on the bed, the knees are located at the corner of the mounting plate 1. The mounting plate 1 is L-shaped, and the inner wall of the mounting plate 1 is longitudinally slidably connected to a lifting seat 9. A plurality of hydraulic rods 15 for driving the lifting seat 9 to slide longitudinally are fixedly connected to the inner side of the mounting plate 1. The lifting seat 9 is lifted and lowered by contracting the hydraulic rods 15. One side of the lifting seat 9 is elastically rotatably connected to a U-shaped block 4, and both ends of the U-shaped block 4 pass through the mounting plate 1. A mounting seat 5 is rotatably connected, and its function is that the angle of the knee will change during the process of lifting the legs upward. Therefore, the rotatable connection method can ensure that the relative position of the mounting seat 5 and the patient's knee is fixed, and can rotate with the change of the knee angle. A plurality of inserts 12 are fixedly connected to the upper surface of the mounting seat 5, and a soft pad 2 plugged with the inserts 12 is slidably connected to the upper surface of the mounting seat 5. The lifting seat 9 is used to lift and lower the U-shaped block 4, that is, when the patient lies on the bed, the knees of the two legs are respectively located at the positions of the two mounting seats 5, and the mounting seat 5 is used to lift and lower the legs of the patient. The soft pad 2 on the mounting seat 5 can ensure the comfort of the patient's knees, and after the mounting seat 5 drives the patient's legs to rise to the corresponding height, the soft pad 2 can slide on the mounting seat 5 to achieve the patient's legs being spread open, and the outer top surface of the mounting plate 1 is provided with a sliding groove 13 for embedding and accommodating the mounting seat 5 and the soft pad 2. The sliding groove 13 ensures that the surface of the soft pad 2 is flush with the outer top surface of the mounting plate 1 when not in use, thereby ensuring that there is no interference when the patient sits on the mounting plate 1, and the upper surface of the mounting seat 5 is fixedly connected with a sliding groove 13 embedded in the lower surface of the soft pad 2 and used to drive the soft pad 2. The electric telescopic rod 11 on which the pad 2 slides can be extended and retracted to realize the sliding of the soft pad 2 on the mounting seat 5, and with the assistance of the insertion tube 12, it is ensured that the soft pad 2 can only slide on the surface of the mounting seat 5 and along the length direction of the mounting seat 5, and the height of the soft pad 2 will not change during the sliding of the soft pad 2. One side of the upper surface of the soft pad 2 is hollowed out, and the other side is provided with a strap 3 for fixing the knees of a person. By passing one end of the strap 3 through the hollow part, the knees of the patient's legs can be bound to the soft pad 2, thereby ensuring that the knees can move with the movement of the soft pad 2.

[0024] In order to ensure that the soft pad 2 will not pull the legs of the pregnant woman when the pregnant woman's knees are raised, and to ensure the stability of the pregnant woman's legs during the inspection and sampling process: a turbine spring shaft 14 is fixedly connected to the top edge of the side of the lifting seat 9, and both ends of the turbine spring shaft 14 pass through the U-shaped block 4 and are provided with turbine springs. Torque sensors 10 are provided between the turbine springs and the U-shaped block 4 at both ends of the turbine spring shaft 14. The turbine spring shaft 14 ensures that the U-shaped block 4 is in a vertical state when not in use. When the patient's legs are raised, the horizontal distance between the knees and the patient's waist will be shortened, thereby driving the mounting seat 5 and the U-shaped block 4 to overcome the elastic force of the turbine spring shaft 14 and swing. The torque sensor 10 can monitor the torque of the U-shaped block 4 in real time to prevent the U-shaped block 4 from affecting the patient's legs due to excessive torque. The reaction traction force is too large, which is used to adjust the patient's position in time, that is, the patient's body moves toward the mounting plate 1, reducing the swing amplitude of the U-shaped block 4, and thereby reducing the torque. A plurality of protrusions 6 are fixedly connected to the outer wall of one side of the U-shaped block 4, and the inner top surface of the mounting plate 1 is located on one side of the plurality of protrusions 6 and is extended and fixedly connected to an electric push rod 7, and the telescopic end of the electric push rod 7 is fixedly connected to a rubber pad 8 that is plugged into the extension portion of the mounting plate 1 and is used to be embedded in the plurality of protrusions 6. The length direction of the rubber pad 8 is equal to the horizontal depth direction of the sliding groove 13. After the patient's legs are lifted to the corresponding height and spread open, the electric push rod 7 is extended to move the rubber pad 8 to the protrusion 6 embedded in the corresponding position, and the friction force is used to fix the position of the protrusion 6, thereby fixing the swing angle of the U-shaped block 4.

[0025] Working principle: fix the mounting plate 1 at the foot of the bed, take a leucorrhea sample, the patient sits on the mounting plate 1, and then lies on the bed, use the straps 3 to fix the patient's knees on the soft pad 2, and the electric push rod 7 contracts to realize the lifting seat 9 to drive the U-shaped block 4, the mounting seat 5 and the soft pad 2 to the corresponding height, and then after the patient's legs are raised to the corresponding height, the electric telescopic rod 11 extends to realize the soft pad 2 sliding on the mounting seat 5, so that the patient's legs can be opened.

[0026] The wiring diagram of the electric telescopic rod 11, the electric push rod 7, the torque sensor 10 and the hydraulic rod 15 in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the electric telescopic rod 11, the electric push rod 7, the torque sensor 10 and the hydraulic rod 15 are not explained in detail.
