The device has multiple massage modes and can adapt to different puerperas, which helps the uterus of the puerpera to recover better and improves the practicality of the device.

[0004] Although the above-mentioned device rotates and presses the area around the navel by pressing balls, in reality, doctors usually adopt a fist-clenching posture, taking the thenar muscle group as the main force body, and transmitting the force to the patient's navel area through the metacarpophalangeal joint.

DETAILED DESCRIPTION

[0033] The embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0034] Example one:

[0035] As shown in the accompanying Figure 1 to the accompanying Figure 10 The present application provides a kind of obstetric nursing abdominal pressure device, including bed 1, the bottom of bed 1 is connected to ground by four groups of support leg 101, moving frame 2, moving frame 2 is arranged in parallel on the upper side of bed 1, translation mechanism 3, translation mechanism 3 is arranged at the outer side of bed 1, for realizing moving frame 2 along the long axis of bed 1 moves, shell 5, shell 5 is arranged in the inside of moving frame 2, air cylinder 4, air cylinder 4 cylinder body is fixedly installed at the top of moving frame 2, its piston rod is fixedly connected with the top of shell 5 by moving frame 2, for realizing shell 5 along Z axis lifting, adjusting mechanism 6, adjusting mechanism 6 is arranged in the inside of shell 5, pressing mechanism 7, pressing mechanism 7 is circumferentially equidistantly arranged at the lower side of adjusting mechanism 6, the radial adjustment of pressing point is realized by adjusting mechanism 6, vibration mechanism 8, vibration mechanism 8 is circumferentially equidistantly arranged at the top of adjusting mechanism 6, mechanical vibration is transmitted to pressing mechanism 7 by adjusting mechanism 6, the bottom of shell 5 is provided with camera 9, the top of moving frame 2 is provided with screen one 10 and screen two 11 respectively, camera 9 and screen one 10 are electrically connected, pressure sensor 710 and stepper motor three 703 and screen two 11 are electrically connected.

[0036] From the above, when using the device, first, the patient to be pressed lies flat on the bed surface of the bed 1, then the moving frame 2 is translated through the translation mechanism 3, and the picture taken by the camera 9 is viewed in real time through the screen 1 0, after the moving frame 2 moves to the patient's adaptive position, the air cylinder 4 is started to make the shell 5 descend along the Z axis until the camera 9 is attached at the patient's navel, the radial position of the pressing mechanism 7 is adjusted through the adjusting mechanism 6, and targeted adjustment is made according to the fatness or illness of the patient, the patient's navel around is continuously and accurately pressed through the pressing mechanism 7, and the pressing strength is monitored and viewed in real time through the pressure sensor 710 and the screen 2 1, so as to avoid that the effect is poor due to weak pressing or the patient is in pain due to strong pressing, in this process, the pressing mechanism 7 is rhythmically micro-vibrated through the vibration mechanism 8, so as to make the myometrial layer produce resonance response, enhance blood perfusion and metabolic waste removal efficiency.

[0037] Example two:

[0038] As shown in the accompanying drawings, Figure 2 to the accompanying drawings, Figure 3 It is basically the same as the previous embodiment, the difference lies in that the translation mechanism 3 includes two groups of fixed plates 301 fixedly connected on the front and rear sides of the bed 1, the two groups of fixed plates 301 are rotatably connected with the lead screws 302, the outer side of the rear fixed plate 301 is fixedly connected with the mounting frame 303, the vertical plate outer surface of the mounting frame 303 is fixedly installed with the stepping motor 1 304, the output end of the stepping motor 1 304 extends to the inside of the mounting frame 303 and is fixedly connected with the driving wheel 305, the driving wheel 305 is drivingly connected with the driven wheel 307 through the belt 306, one end of the two lead screws 302 is fixedly connected with the driving wheel 305 and the driven wheel 307 respectively, and the moving frame 2 is threadedly connected with the two lead screws 302.

[0039] From the above, when moving the moving frame 2, the stepping motor 1 304 is started, the stepping motor 1 304 drives the driving wheel 305 to rotate, the driving wheel 305 drives the driven wheel 307 to rotate synchronously through the belt 306, and the driving wheel 305 and the driven wheel 307 drive the two lead screws 302 to rotate in the same direction and at the same speed, since the moving frame 2 is threadedly connected with the two lead screws 302, the accurate movement of the moving frame 2 is completed.

[0040] Example three:

[0041] As shown in the accompanying drawings, Figure 4 to the accompanying drawings, Figure 6As shown, this embodiment is basically the same as the previous embodiment, except that the adjusting mechanism 6 includes several gears 601 circumferentially distributed inside the outer casing 5. The gears 601 are rotatably connected to the top of the inner wall of the outer casing 5 via pins. A ring plate 501 is fixedly connected inside the outer casing 5. Slide grooves 502 are circumferentially equidistantly opened on the outer sides of both the outer casing 5 and the ring plate 501. Rectangular racks 603 are slidably connected inside the slide grooves 502. The rectangular racks 603 mesh with the gears 601. A ring is opened on the inner wall of the outer casing 5. The groove 503 has a toothed ring 602 slidably connected inside it. The toothed ring 602 meshes with the gear 601. A stepper motor 604 is fixedly installed on the top of the housing 5. The output end of the stepper motor 604 extends into the housing 5 and is fixedly connected to one of the gears 601. A connecting plate 605 is fixedly connected to the end of the rectangular rack 603 away from the housing 5. A fixing frame 606 is fixedly connected to the bottom of the connecting plate 605. The outer surfaces of the connecting plate 605 and the fixing frame 606 are both provided with a sliding groove 607.

[0042] As can be seen from the above, when adjusting the radial position of the pressing mechanism 7, the second stepper motor 604 is turned on. The second stepper motor 604 drives a set of gears 601 to rotate. The rotation of gears 601 drives the gear ring 602 to slide in the annular groove 503. The rotation of the gear ring 602 drives the remaining gears 601 to rotate synchronously. At this time, all gears 601 rotate in the same direction and at the same speed. The rotation of gears 601 drives the first rectangular rack 603 to slide along the direction of the first slide groove 502. Since the pressing mechanism 7 is set in the connecting plate 605 and the fixed frame 606, the connecting plate 605 and the fixed frame 606 move with the sliding of the first rectangular rack 603, thereby completing the radial adjustment of the pressing mechanism 7.

[0043] Example 4:

[0044] As attached Figure 7 To be continued Figure 8As shown, this embodiment is basically the same as the previous embodiment, except that the pressing mechanism 7 includes a fixing block 701 fixedly connected to the top of the fixing frame 606, a worm gear 702 rotatably connected between the fixing block 701 and the fixing frame 606, a stepper motor 703 fixedly mounted on the outside of the fixing frame 606, the output end of the stepper motor 703 extending into the interior of the fixing frame 606 and fixedly connected to one end of the worm gear 702, a worm wheel 704 meshing with the outer surface of the worm gear 702, the worm wheel 704 rotating with the fixing frame 606 via a pin, and a rectangular rack slidably connected inside the slide groove 607. A rectangular rack 705 meshes with a worm gear 704. A movable block 706 is fixedly connected to the bottom of the rectangular rack 705. A connecting seat 707 is provided on the lower side of the movable block 706. Sliding grooves 708 are provided on both opposite sides of the movable block 706. A connecting rod 709 is slidably connected inside the sliding grooves 708. The connecting rod 709 is fixedly connected to the connecting seat 707. A pressure sensor 710 is provided at the bottom of the movable block 706. A spring 711 is fixedly connected between the pressure sensor 710 and the connecting seat 707. A pressing block 712 is detachably provided at the bottom of the connecting seat 707.

[0045] As can be seen from the above, when the pressing mechanism 7 presses, the stepper motor 703 is activated, which drives the worm gear 702 to rotate. The rotation of the worm gear 702 drives the worm wheel 704 to rotate, and the rotation of the worm wheel 704 drives the rectangular rack 705 to slide along the slide groove 607, causing the movable block 706 to descend vertically, which drives the pressing block 712 to press on the patient's abdomen. The pressing block 712 can also be quickly replaced. As the pressing block 712 descends, the connecting seat 707 slides in the slide groove 708 through the connecting rod 709, causing the spring 711 to contract. This increases the pressure of the spring 711 on the pressure sensor 710. The relevant data from the pressure sensor 710 is transmitted to the screen 11 in real time. When the data detected by the pressure sensor 710 reaches the standard value, the stepper motor 703 is turned off, thereby applying standard abdominal pressure to the patient and avoiding the situation where the doctor is overworked and the abdominal pressure effect is reduced.

[0046] Example 5:

[0047] As attached Figure 9As shown, this embodiment is basically the same as the previous embodiment, except that the vibration mechanism 8 includes a bearing plate 801 fixedly connected to the top of the connecting plate 605. A drive motor 802 is fixedly installed on the rear side of the bearing plate 801. The output end of the drive motor 802 extends to the front side of the bearing plate 801 and is fixedly connected to a turntable 803. A fixed column 804 is eccentrically arranged on the front side of the turntable 803. A rotating plate 805 is rotatably connected to the outer surface of the fixed column 804. One end of the rotating plate 805 away from the fixed column 804 is rotatably connected to the bearing plate 801 through a connecting column 806. A hinge frame 807 is provided in the middle of the rotating plate 805. The rotating plate 805 is rotatably connected to the inside of the hinge frame 807 through a pin. A guide member 808 is fixedly connected to the front side of the bearing plate 801. A push rod 809 is slidably connected inside the guide member 808. The upper end of the push rod 809 is fixedly connected to the hinge frame 807. A striking block 810 is fixedly connected to the lower end of the push rod 809.

[0048] As can be seen from the above, when the pressing mechanism 7 is vibrated, the drive motor 802 is turned on, and the drive motor 802 drives the turntable 803 to rotate. The rotation of the turntable 803 drives the rotating plate 805 to tilt periodically through the fixed column 804 and the connecting column 806. Then, through the cooperation of the hinge frame 807 and the guide member 808, the striking block 810 below the push rod 809 periodically strikes and vibrates the connecting plate 605. The vibration of the connecting plate 605 drives the fixed frame 606 to vibrate synchronously, thereby transmitting the vibration frequency to the pressing mechanism 7, so that the pressing mechanism 7 vibrates continuously when pressing the patient's abdomen, thereby enhancing the efficiency of blood perfusion and metabolic waste removal.
