Description

Shank support for dual-energy bone densimeter

Technical Field

The utility model relates to a shank bracket for a dual-energy bone densitometer, belonging to the technical field of medical auxiliary instruments.

Background

A dual energy X-ray absorptiometry (DXA) is a device for non-invasively detecting bone mineral density, the accuracy of detecting bone mineral density by using the dual energy bone mineral density meter is high, and the method by using the dual energy bone mineral density meter is a standard method for diagnosing osteoporosis and monitoring bone mineral density change. The method adopts a dual-energy X-ray absorption method, the detection result is expressed by the area bone density (bone mineral density, BMD), and the calculation formula is as follows: BMD (g/cm 2) =bone mineral content (g)/(area (cm 2)).

As can be seen from the calculation formula of BMD, when the bone mineral content is fixed, if the detected area is changed, the BMD result is inevitably changed. The detection area has close relation with the body position of the detected person, under different body positions, the detection area after X-ray projection can be changed, and especially when the density of the lumbar vertebra positive bone of the human body is detected, the influence of the body position of the detected person on the detection area is obvious.

The lumbar vertebra of the human body is physiologically curved, and when the human body lies flat, the lumbar vertebra cannot be laid flat and can not be attached to the bed surface; if the lumbar vertebra flatly-adhered bed surface is realized, a foam cushion block is needed to be placed at the lower part of the lower leg, the lower leg is lifted, when the angle between the thigh and the bed surface is in a range of 60-90 degrees, the lumbar vertebra is in a substantially flat state, the bending of the lumbar vertebra when the foam cushion is placed under the lower leg and the foam cushion is not placed is shown as shown in figure 1, wherein an upper picture is a bending indication of the lumbar vertebra when the cushion block is not placed under the lower leg, a lower picture is a vertebral schematic diagram when the cushion block is placed under the lower leg, the difference of the projection area of the lumbar vertebra when the cushion block is placed under the lower leg and the lumbar vertebra when the cushion block is not placed is compared with that shown as shown in figure 2, the difference of the projection area of the lumbar vertebra in the two states is larger, the difference of the angle between the thigh and the bed surface is visible, the physiological curvature of the lumbar vertebra is influenced, the projection area of the lumbar vertebra is directly influenced, and the accuracy of the lumbar vertebra in the normal bone density is influenced. Therefore, the placement of the posture is of great importance when the dual-energy bone densitometer is used for detecting the lumbar vertebra orthotopic bone density.

Currently, when a dual-energy bone densitometer detects lumbar normal bone density, there are two body positions: the first posture is to separately detect the normal bone density of the lumbar vertebra, and a foam cushion block matched with a bone densitometer is required to be placed at the lower part of the lower leg so as to reduce the physiological curvature of the lumbar vertebra and further reduce the overlapping of adjacent vertebral bodies; the second posture is to detect lumbar vertebra righting and proximal femur at one time, and the foam cushion block is not needed to be placed. The two body positions and the measured lumbar vertebra normal bone density result are different, and the two body positions can not be mixed during follow-up, and the first body position is usually adopted for detection more.

The foam cushion block matched with the dual-energy bone densimeter is cuboid, has unequal length, width and height so as to adapt to different crowds with different heights and has larger height, and the foam cushion block is erected so as to increase the height and raise the lower leg; the height is smaller, the foam cushion block is horizontally laid down, so that the height is reduced, and the lower leg is lowered; the height is centered, and the foam cushion block is laterally placed, so that the height is moderate, and the height of the lower leg is adjusted.

The foam cushion block which is matched with the dual-energy bone densimeter is of a fixed shape and size, namely the length, the width and the height of the foam cushion block are specific, for each subject which is different in height and is subjected to bone density detection, the height of the raised lower leg and the angle between the thigh and the bed surface are not customized, the universality is poor, the position data of the foam cushion block cannot be accurately set, and when the bone density is checked, the same position as that when the bone density is first measured cannot be set, and the comparison between the bone density check and the treatment is directly influenced. In addition, the angle between the thigh and the bed surface can be influenced by the position of the foam cushion block moving on the bed body in the use state.

The Chinese patent with the issued bulletin number of CN215605883U discloses an ultrasonic bone mineral density measuring bracket, which belongs to the technical field of medical appliances and comprises a solid plate and a bracket, wherein the bracket supports the solid plate; the solid plate is an arc plate with high two sides and low middle, and a sole baffle is arranged at one side end of the solid plate; the patent is also provided with a limiting through hole which is arranged at the bottom of the solid plate and is close to the sole baffle end. The patent solves the problem that when a patient carries out ultrasonic bone mineral density detection, the lower leg is fixed when the tibia is measured on the patient, but the patent is suitable for detecting the tibia mineral density of children, but is not suitable for detecting the lumbar vertebra normal bone mineral density of adults, the patent is only suitable for supporting one lower leg, the bottom of a bracket is provided with a movable wheel, the position is ensured to be kept when the patent is used, one lower leg is lifted independently, when one lower leg is lifted, the angle bending change of the lumbar vertebra of a person to be detected still can not meet the detection requirement, and when the single lower leg is lifted, the lumbar vertebra of the person to be detected can be caused to turn over in the corresponding left-right direction, so that new influence factors are caused, and the detection of the lumbar vertebra normal bone mineral density is unfavorable.
