Intelligent adjustable midwifery device and application method

Abstract

The invention relates to an intelligent adjustable midwifery device and an application method. The intelligent adjustable midwifery device comprises a fixed supporting pad, a hemisphere assembly, a self-adaptive adjusting unit and a state adjusting unit. The self-adaptive adjusting unit achieves multi-dimensional swinging or locking of the hemispheroid assembly through a first semicircular rotating ring, a second semicircular rotating ring and an adjustable damping sliding block, wherein the first semicircular rotating ring and the second semicircular rotating ring are crossed. The state adjusting unit adjusts the position and angle of the ball through the lifting and overturning unit. The device has four core forms: a sitting posture pelvis swinging form (sphere self-adaptive swinging); the kneeling and groveling position waist supporting state (the ball body is locked and stably supports the abdomen and the knees together with the supporting pad); the standing posture is in a ball leaning state (the ball body rises to provide lumbosacral support capable of being pressed actively); and in the sitting posture waist and back supporting state, the ball body inclines backwards and is locked, and the ball body and the supporting pad form a seat with a waist rest. Various delivery auxiliary functions are integrated, intelligent switching can be achieved, and the contradiction that stability and functionality of a traditional guide ball cannot be achieved at the same time is fundamentally solved.

Description

Technical Field

[0001] This invention relates to the field of obstetric medical device technology, and more specifically, to a gynecological obstetric medical delivery device and its application method. Background Technology

[0002] Childbirth is a natural physiological process for women, but it is often accompanied by severe pain. To alleviate labor pain and promote the progress of labor, birthing balls (also known as labor balls) are widely used clinically as a non-pharmacological analgesic and postural aid. By sitting on a birthing ball, mothers can perform pelvic rocking and rotation exercises, which helps relax pelvic floor muscles, relieve pressure on the lumbosacral region, promote fetal head descent, and allow for a degree of freedom of movement in a comfortable position, enhancing their sense of autonomy during childbirth.

[0003] However, existing labor balls have a significant drawback in use: insufficient stability. As an independent, rolling sphere, a labor ball is prone to tipping over or sliding when bearing weight and moving, especially when the mother is fatigued, unbalanced, or needs to exert force, posing a safety hazard. This not only increases the mother's anxiety but also limits its use in certain positions (such as squatting or large swinging movements). Currently, a common solution to the instability of labor balls is to use a ring frame or base with a groove at the bottom to fix the ball's base. While this structure largely solves the safety problem of the ball rolling, its fundamental flaw lies in severely limiting the core function of the labor ball. The fixed ball's swing amplitude, direction, and the interaction between the body and the ball are strictly constrained by the rigid frame, almost completely losing the multi-dimensional, adaptive pelvic movement and support functions that the original labor ball could provide, reducing it to a simple, fixed-position cushion or backrest with limited functionality.

[0004] A pressing contradiction exists in existing technologies: how to effectively improve the safety and stability of labor balls while preserving or even expanding their original, flexible functions to the greatest extent possible. Therefore, a new type of midwifery device is needed that not only provides stable support and eliminates safety hazards like a traditional fixed frame, but also intelligently adapts to different stages of labor and the needs of different mothers, flexibly switching between various functional modes such as "free movement" and "stable support," thus truly achieving a balance between safety and functionality. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a midwifery device and its application method for obstetrics and gynecology, in view of the above-mentioned defects of the prior art.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] An intelligent adjustable midwifery device is constructed, comprising a support pad, a hemispherical assembly, an adaptive adjustment unit, and a state adjustment unit;

[0008] The support pad includes a rigid mounting area and a soft area for lying down or kneeling.

[0009] The hemispherical assembly includes an inflatable hemispherical capsule and a rigid mounting plate that is sealed to the edge of the hemispherical capsule.

[0010] The adaptive adjustment unit includes a connecting shaft that is horizontally rotatably connected to the rigid mounting plate, a first semi-circular rotating ring, and a second semi-circular rotating ring; the first semi-circular rotating ring and the second semi-circular rotating ring are arranged in a cross shape.

[0011] The inner wall of the first semi-circular rotating ring is provided with a first semi-circular slide rail, and a first slider is slidably disposed on the first semi-circular slide rail. The first slider is fixedly connected to the connecting shaft. The first slider is provided with a first position sensor for detecting its position and a first damping unit with adjustable damping force acting on the first semi-circular slide rail.

[0012] The inner wall of the second semicircular ring is provided with a second semicircular slide rail, and a second slider is slidably disposed on the second semicircular slide rail. The second slider is fixedly connected to the middle of the outer surface of the first semicircular ring. The second slider is provided with a second position sensor for detecting its position and a second damping unit with adjustable damping force acting on the second semicircular slide rail.

[0013] The state adjustment unit includes a flipping unit that drives the adaptive adjustment unit to rotate 90 degrees longitudinally and a lifting unit that drives the flipping unit to rise and fall.

[0014] Preferably, the device further includes a control host, which receives data from the first position sensor and the second position sensor, and controls the operation of the first damping unit, the second damping unit, the tilting unit, and the lifting unit.

[0015] Preferably, both the first damping unit and the second damping unit include a drive motor, and the movable end of the drive motor is provided with a rubber cam.

[0016] Preferably, the rubber cam is in a free state when it is not in contact with the first semicircular slide rail or the second semicircular slide rail at all.

[0017] When the drive motor is stationary under the control of the control host, the rubber cam contacts the first semi-circular slide rail or the second semi-circular slide rail to provide damping friction force, and the damping force is adjusted by the degree of compression between the protrusion of the rubber cam and the first semi-circular slide rail or the second semi-circular slide rail.

[0018] When the drive motor is in a rotating state under the control of the control host, the protrusion of the rubber cam contacts the first semi-circular slide rail or the second semi-circular slide rail to provide driving force.

[0019] Preferably, the upper end of the connecting shaft is rotatably connected to the rigid mounting plate via a bearing, and the interior of the connecting shaft is provided with an inflation / deflation unit and an inflation / deflation pipeline for inflating and deflation of the hemispherical bladder; the connecting shaft is provided with an air slip ring that cooperates with the inflation / deflation pipeline; the inflation / deflation unit is connected to and controlled by the control host.

[0020] Preferably, the flipping unit includes a flipping motor; the lifting unit includes an L-shaped support frame, on which a longitudinal slide rail is provided, and on which a mounting seat for mounting the flipping motor is slidably disposed; and on which a lead screw assembly is provided to drive the mounting seat to lift.

[0021] The present invention also provides a method for applying the above-mentioned intelligent adjustable midwifery device, wherein the method includes adjusting the states of the adaptive adjustment unit, the state adjustment unit, and the hemispherical component to switch the device between at least one of the following functional modes:

[0022] A. Seated pelvic swing pattern, wherein the adaptive adjustment unit is in a movable state, allowing the hemispherical assembly to swing adaptively in the horizontal plane.

[0023] B. Kneeling / prone lumbar support configuration, wherein the support pad is placed horizontally to support the user's knees, and the adaptive adjustment unit is locked to fix the hemispherical assembly under the user's abdomen.

[0024] C. Standing posture with the ball back, wherein the adaptive adjustment unit is in a movable state, and the hemispherical component is placed behind the user's lumbosacral region for leaning;

[0025] D. Seated lumbar support configuration, wherein the adaptive adjustment unit and the flipping unit are locked, and the hemispherical assembly provides conformal support for the user's lumbar and back.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. Multifunctional integration and intelligent switching: Through the innovative adaptive adjustment unit structure and state adjustment unit, this invention integrates multiple application functions of the labor ball and can intelligently switch between four core modes (A, B, C, and D) with one click or preset program through the control system. This multifunctional design greatly improves equipment utilization and the continuity of childbirth assistance.

[0028] 2. Perfect balance of safety and functionality: It fundamentally solves the problem of poor stability in traditional labor support balls. In situations requiring free movement, the adaptive adjustment unit provides controllable damping, ensuring that the ball swings adaptively in multiple directions within a safe range, while also providing necessary resistance or locking support when the mother loses balance. In situations requiring stable support, the locking damping unit can achieve rigid fixation, providing stable and reliable support without any worries.

[0029] 3. Height Adjustable and Personalized Fit: The lifting and flipping units allow the height and angle of the device to be finely adjusted according to the mother's height, body shape, and specific usage needs, achieving personalized ergonomic fit and improving comfort and usability.

[0030] 4. Intelligent interaction and data feedback: The position sensor and control system can monitor the motion parameters such as the swing amplitude and frequency of the hemisphere in real time and feed the data back to the mother or medical staff. This data can be used to guide childbirth, assess the condition, or conduct safety monitoring, thereby improving the scientific nature and controllability of the childbirth process.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0036] like Figures 1 to 3 As shown, this embodiment provides an intelligent adjustable midwifery device, which mainly includes a support pad 1, a hemispherical assembly 2, an adaptive adjustment unit 3, and a state adjustment unit 4.

[0037] The support pad 1 is typically placed on the floor or bed surface and includes a hard mounting area 10 and a soft lying / kneeling area 11. The hard area 10 is used to connect to the position adjustment unit 4 to ensure structural stability; the soft area 11 is made of materials such as high-density sponge and memory foam, and the surface can be covered with non-slip and breathable fabric to provide comfortable support for the mother's knees, hips, etc.

[0038] The hemispherical assembly 2 simulates the function of a traditional doula ball, comprising an inflatable hemispherical capsule 20 and a rigid mounting plate 21. The hemispherical capsule 20 is made of medical-grade elastic material, and its stiffness and size can be adjusted by inflation and deflation. The rigid mounting plate 21 is sealed to the edge of the capsule and is horizontally rotatably connected to the connecting shaft 30 of the adaptive adjustment unit 3 via bearings.

[0039] The adaptive adjustment unit 3 is the core of this invention for achieving multi-functional switching. It includes a connecting shaft 30, a first semi-circular rotating ring 31, and a second semi-circular rotating ring 32. The first semi-circular rotating ring 31 and the second semi-circular rotating ring 32 are arranged in a cross shape, together forming a universal structure that allows the connecting shaft 30 (thus driving the hemispherical assembly 2) to move at large angles within the spherical coordinate system. The first slider 33 can slide on the first semi-circular slide rail 34, driving the connecting shaft 30 to move along the trajectory of the first semi-circular rotating ring 31. The second slider (see the first slider structure) slides on the second semi-circular slide rail (see the first semi-circular slide rail structure), driving the entire first semi-circular rotating ring 31 to move along the trajectory of the second semi-circular rotating ring 32. The first position sensor 35 (e.g., using a gyroscope) and the second position sensor (see the first position sensor structure) are used to monitor the positions of the first slider 33 and the second slider (see the first slider structure) in real time, respectively. The spatial attitude of the hemispherical assembly 2 can be determined by the positions of the first slider 33 and the second slider (see the first slider structure).

[0040] The upper end of the connecting shaft 30 is rotatably connected to the rigid mounting plate 21 via the bearing 300. The interior of the connecting shaft 30 is provided with an inflation / deflation unit 301 and an inflation / deflation pipeline 302 for inflating and deflation of the hemispherical bladder 20. An air slip ring 303 is provided on the connecting shaft 30 to cooperate with the inflation / deflation pipeline 302. The inflation / deflation unit 301 is connected to and controlled by the control host.

[0041] The first damping unit 36 ​​and the second damping unit (see the structure of the first damping unit) are the core execution and locking components, such as... Figure 2 As shown, it includes a drive motor 360 and a rubber cam 361 disposed at its movable end:

[0042] When the drive motor 360 is stationary, and the protrusion of the control rubber cam 361 contacts the slide rail (first semi-circular slide rail 34 and second semi-circular slide rail (see the structure of the first semi-circular slide rail)) with different pressures (the motor finely adjusts the angle of the rubber cam 361), it can provide an adjustable damping force, from zero (free state) to maximum (locked).

[0043] When the drive motor 360 rotates, the rubber cam 361 can push the slider to move along the slide rail (by utilizing the deformability of the rubber cam 361), providing active driving force (in this form, the pregnant woman's movements are driven by the active movement of the ball).

[0044] The state adjustment unit 4 includes a flipping unit 40 and a lifting unit 41. The flipping unit 40 can be driven by a flipping motor to rotate the adaptive adjustment unit 3 90 degrees around the horizontal axis (90 degrees is the maximum angle, and the angle can also be adjusted within 90 degrees as needed), realizing the switching of the device between sitting and kneeling support functions. The lifting unit 41 includes an L-shaped support frame, a longitudinal slide rail, a mounting base, and a lead screw assembly (this part is an existing lifting structure, which will not be described in detail), and can drive the flipping unit 40 and all the above components to adjust the height in the vertical direction.

[0045] The device is also equipped with a control host (not shown in the figure), which is used to receive sensor signals and control various actuators such as motors and inflation / deflation units to achieve automated control and switching between different functional modes.

[0046] Specific implementation steps for each form:

[0047] A. Seated pelvic tilt pattern:

[0048] Users can select "Mode A" via a control terminal (such as a remote control or panel). The control host executes the following automatic sequence:

[0049] a) Control the lifting unit 41 to adjust the mounting base (along with the flipping unit 40, adaptive adjustment unit 3 and hemispherical assembly 2 above it) to the preset sitting height. At this time, the relative height between the top of the hemispherical assembly 2 and the upper surface of the support pad 1 is suitable for sitting use.

[0050] b) Control the flipping unit 40 to ensure that the adaptive adjustment unit 3 is in the initial vertical position (i.e., the connecting shaft 30 is approximately vertical).

[0051] c) Control the first and second damping units to set the adaptive adjustment unit 3 to "free" or "low damping" state.

[0052] d) Control the inflation / deflation unit to inflate the hemispherical bladder 20 to the preset elastic pressure.

[0053] Operation: The mother sits on hemispherical component 2. When the mother performs pelvic movements, hemispherical component 2 swings in multiple dimensions.

[0054] B. Kneeling / prone position with lumbar support:

[0055] Mode switching: The user selects "Mode B". The control host executes:

[0056] a) Control the lifting unit 41 to adjust the upper structure such as the mounting base to a suitable height so that the hemispherical component 2 is located in the predetermined space below the abdomen of the mother when she is kneeling or prone.

[0057] b) The flipping unit 40 does not operate, and the adaptive adjustment unit 3 maintains the initial vertical position.

[0058] c) Control the first damping unit 36 ​​and the second damping unit (see the structure of the first damping unit) to lock the adaptive adjustment unit 3 (here, locking refers to the state of larger damping friction, not complete locking) so that the position and angle of the hemispherical assembly 2 are fixed.

[0059] d) Adjust the inflation volume of the hemispherical 20 according to the mother's body shape.

[0060] Instructions for use: The mother assumes a kneeling or prone position. Support pad 1 (installation area 10) supports the mother's knees and calves. The locked hemispherical component 2 is located directly below the mother's abdomen, providing unsupported space for the abdomen and stable support for the lumbosacral region. In this configuration, both support pad 1 and hemispherical component 2 are fixed and connected as a stable, integrated support structure via the locked adaptive adjustment unit 3.

[0061] C. Standing position with the ball:

[0062] Mode switching: The user selects "C mode". Control host execution:

[0063] a) Control the lifting unit 41 to raise the upper structure such as the mounting base to an appropriate position so that the top of the hemispherical assembly 2 matches the height of the user's lumbosacral region.

[0064] b) The flipping unit 40 drives the mounting base to rotate 90 degrees, so that the hemispherical component 2 is in a horizontal position.

[0065] c) Set the adaptive adjustment unit 3 to the "medium damping" state.

[0066] d) Inflate hemisphere 20 to a relatively firm degree.

[0067] Operation: The mother stands or half-squats with her back to the device, resting her lumbosacral region against the hemispherical component 2. As the body moves, the sphere swings adaptively via the adaptive adjustment unit 3.

[0068] D. Seated lumbar support posture:

[0069] Form switching: The user selects "D form". Control host execution:

[0070] a) Control the lifting unit 41 to adjust the upper structure such as the mounting base to the standard sitting height so that the support point of the hemispherical component 2 corresponds to the back position of the user sitting on the support pad 1.

[0071] b) Control the flipping unit 40 to flip the adaptive adjustment unit 3 and the hemispherical assembly 2 as a whole by an angle (e.g., 10-30 degrees).

[0072] c) Control the first damping unit 36 ​​and the second damping unit (see the structure of the first damping unit) to lock the adaptive adjustment unit 3 (here, locking refers to the state of larger damping friction, not complete locking).

[0073] d) Inflate the hemisphere 20 until it is full and firm.

[0074] Instructions for use: The mother sits on the fixed support cushion 1. The hemispherical component 2, which flips back and locks in place, provides stable and close support for her lower back. The support cushion 1 serves as the fixed seat surface, and the hemispherical component 2 serves as the fixed backrest, together forming a stable sitting support system.

[0075] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
