The utility model relates to the technical field of fitness equipment, and particularly provides a tail bone limiting device and a leg bending and lifting trainer, the tail bone limiting device comprises a supporting piece, a supporting rod, a supporting rod and a supporting rod, the supporting piece is detachably arranged on a longitudinal beam, and the supporting piece is perpendicular to the longitudinal beam; the limiting piece is fixedly arranged on the supporting piece; the lifting assembly is arranged on the limiting piece, and the lifting assembly is used for abutting against the tail bone position of a user; wherein the lifting assembly is arranged above the backup plate. The degree of standardization of training postures is remarkably improved, the training key points are more concentrated on the clepper rope muscles, the muscle shaping and strengthening effect is enhanced, the back surface chain muscle group is particularly strengthened, the phenomenon that the waist curve is too large can be effectively improved, the lumbago is relieved, and by preventing the incorrect body position and excessive lifting, the user experience is improved. Muscle strain and joint pressure risks are remarkably reduced, back injury is prevented, and safe and efficient training experience is provided for users.

The invention discloses an auxiliary power assisting device with a waist support and a working method of the auxiliary power assisting device, and belongs to the technical field of wearing power assisting assistion.The auxiliary power assisting device with the waist support comprises a walking supporting frame, a waist support, a rotating supporting arm, a driving mechanism, a waist supporting plate and a buffering mechanism; the buffering mechanism is used for buffering the waist supporting plate moving towards the outer side of the waist support. According to the invention, after a wearer wears the walking supporting frame, the walking supporting frame assists in supporting the wearer, in addition, when the wearer lifts a heavy object to a high position, the waist supporting plate abuts against the waist and back of the wearer, so that the waist and back are supported by the waist supporting plate during lifting, and then the waist and back are supported in an auxiliary manner; in addition, by arranging a buffering mechanism, the buffering mechanism can achieve the buffering and vibration reduction effect on the waist supporting plate, and therefore the extrusion force of the waist supporting plate on the waist and the back is not too large.

Operating room tables have limited height adjustment capability. To adequately treat a patient, surgeons often have to risk back injury and / or stand on rickety piles of prior art step stools, which is unsafe and can compromise sterility. Here, a computer-processor-controlled, motorized, surgical step-platform device is disclosed. The device is configured to have dimensions similar to a step stool. The device is configured to easily slide across a floor to an operating table. Then, either by a built-in user interface, or by remote control from a Smartphone, the device can affix itself into position and automatically raise between 5 to 18 inches above the floor. The device has sophisticated rechargeable battery power management and further accommodates wired, and wireless foot switches to control nearby surgical equipment.

This invention belongs to the field of sports science and sports medicine, and discloses a swimmer's back injury early warning system and method based on multimodal temporal information fusion. It includes a data acquisition module for simultaneously acquiring temporal data of the swimmer's kinematics, electromyography, and biomechanics; a data processing and feature extraction module connected to the data acquisition module for preprocessing and aligning the acquired raw data, and extracting kinematic, electromyographic, and biomechanical features to form a multimodal feature sequence; and an injury risk early warning model module storing a pre-trained multimodal temporal fusion injury risk early warning model, receiving the multimodal feature sequence output from the data processing and feature extraction module, and calculating and outputting the injury risk probability value and risk level. This system features multi-dimensional fusion, temporal dynamic modeling, personalized early warning, high precision, and real-time performance.

The invention belongs to the field of furniture, and discloses a backrest rotation center self-adaptive adjustment method which comprises the following steps: step 1, collecting seat surface pressure, identifying the positions of ischial tuberosities on two sides of a human body according to the seat surface pressure distribution, and calculating the positions of hip joints of the human body according to the positions of the ischial tuberosities on two sides of the human body; 2, according to the position of the hip joint of the human body, adjusting the rotation center of the backrest to move to the position the same as the coordinates of the hip joint of the human body in the front-back direction. The position of the human ischial tuberosity point on the seat surface is detected, the position of the human trunk rotating shaft is calculated, the rotating center of the backrest is adjusted to the position coinciding with the rotating center of the human body in the horizontal direction, the phenomena of back rubbing and waist losing caused by unreasonable arrangement of the rotating shaft of the backrest are eliminated, reasonable support is provided for the human body in the backward leaning state, and the human body is more comfortable. Human body waist and back injury caused by long-term use of unreasonable office chairs is avoided.

The utility model provides a sitting posture pedaling trainer which comprises a bottom plate, a base is arranged on the right side of the upper end of the bottom plate, a backrest frame is rotationally connected to the base, a rotating assembly used for rotating the backrest frame is arranged between the base and the backrest frame, and a backrest cushion is arranged at the upper end of the backrest frame. According to the sitting posture pedaling training device, the position of the backrest cushion can be adjusted through the adjusting assembly so that the training device can better adapt to the size of the body of a person, the angle of the backrest frame can be adjusted through the rotating assembly, and therefore the sitting posture pedaling training device can be more conveniently used. The normal physiological curvature of the spine of the user can be maintained, and the risk of injury to the waist and the back is reduced.
