Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a human bone density prediction device for predicting the risk of osteoporosis occurrence. Background Art

[0002] Osteoporosis develops insidiously and often has no obvious symptoms in the early stage. When symptoms such as pain and fractures appear, bone mass has been severely lost, making treatment difficult and the prognosis poor. Early prediction of osteoporosis can help high-risk populations take timely intervention measures, delay the progression of the disease, reduce the risk of serious complications such as fractures, relieve the pain of patients and the social medical burden, and is of great significance for protecting public health.

[0003] Currently, when predicting osteoporosis, it is necessary to measure the body weight, bone density, etc. of the human body and predict osteoporosis by synthesizing multiple factors. When detecting bone density, dual-energy X-ray equipment is generally used to detect bone density. The dual-energy X-ray equipment mainly emits two different energies of X-rays to penetrate human bones and soft tissues, and uses the difference in the absorption degree of different energy rays by bone minerals to accurately measure bone density and judge the situation of bone loss. It is the gold standard for diagnosing osteoporosis, such as an X-ray bone densitometer disclosed in the patent publication number CN119523515B.

[0004] Although the dual-energy X-ray bone densitometer can detect the bone density of the human body, in the prediction of osteoporosis, the person to be predicted needs to regularly detect bone density to judge the change amount of osteoporosis according to the bone density detected at different times. However, since the posture of the human body will be in different states each time it lies on the detection bed, for example, the separation angle of the legs is different, this will cause deviation when the instrument detects the hip joint, which is not conducive to result comparison and thus affects the prediction accuracy. Summary of the Invention

And through the mutual cooperation of the U-shaped plate, the footrest, the U-shaped leg support, and the support positioning mechanism, based on the position and angle of the legs when a person initially undergoes bone density detection, the legs of subsequent personnel during bone density detection can be positioned and placed at a fixed angle, so as to avoid large deviations in the position and angle of the legs from affecting the accuracy of the osteoporosis prediction result.

[0020] 2. Through the partition weighing unit set, the weight of the human body can be detected synchronously during bone density detection, and the weight ratio of the upper body, the hip, and the legs of the human body can be roughly analyzed, so as to further improve the accuracy of osteoporosis prediction in combination with the bone density detection result.

[0021] 3. Through the disinfection unit set, not only can the leg and foot support positions be quickly disinfected after each person uses it, but also in cooperation with the mutual cooperation of the cylinder barrel, the piston, the T-shaped support frame, the sealed hollow plate, the liquid inlet hole, the shunt pipe, the shunt electric control valve, and the infusion electric control valve, pre-support the bed board to avoid excessive pressure concentration or excessive pressure fluctuation during the process of a person lying flat on the bed from damaging the pressure detector.

The elastic support components 75 include components such as sliding rods, nuts, and springs. The sliding rods are installed at the bottom of the partition plates 74, and the leg support seat 71, the hip support seat 72, and the upper body support seat 73 are slidably connected to the corresponding sliding rods. Springs are arranged between the leg support seat 71, the hip support seat 72, and the upper body support seat 73 and the partition plates 74.

[0032] The disinfection unit 8 is arranged on one side of the bed base 1 and is used for disinfecting the U-shaped leg rest 5 and the footrest 20.

A disinfectant storage tank 92 is installed on the end face of the base 91. A liquid pump 93 is installed on the end face of the base 91. The suction end of the liquid pump 93 is communicated with the interior of the disinfectant storage tank 92. The output end of the liquid pump 93 is installed with an infusion pipe 94. A connecting hose 95 is installed jointly by the infusion pipe 94 and the horizontal pipe 82. A liquid adding hole and a sealing cover are arranged on the top of the disinfectant storage tank 92. A liquid level sensor is also arranged inside it, which is convenient for personnel to add disinfectant in time.

[0033] Cylinder barrels 10 are inserted through the end faces of the leg support seat 71, the hip support seat 72 and the upper body support seat 73. A piston 11 is slidably connected inside each cylinder barrel 10. A T-shaped support member 12 is installed on the top of each piston 11. A sealed hollow plate 13 is fixedly installed on the bottom of the bed board 3. Liquid inlet holes 14 are jointly opened on the end face of the bottom of each cylinder barrel 10 and the end face of the sealed hollow plate 13. A shunt pipe 15 is fixedly inserted into the side wall of the sealed hollow plate 13. The shunt pipe 15 is communicated with the interior of the infusion pipe 94. A shunt electric control valve 16 is installed inside the shunt pipe 15. An infusion electric control valve 17 is installed at a position above the shunt electric control valve 16 inside the infusion pipe 94. Both the infusion electric control valve 17 and the shunt electric control valve 16 are electrically connected to the computer of the dual-energy X-ray detection main body 2. The infusion electric control valve 17 is a normally open valve, and the shunt electric control valve 16 is a normally closed valve.

[0034] Linear movement modules 18 are installed on both side walls of the partition plate 74 above the leg support seat 71. The linear movement modules 18 are used for driving the U-shaped plate 4 to move along the leg support seat 71. The linear movement modules 18 drive the screw rod through a motor to drive the slider to move, so that the U-shaped plate 4 moves. This is a mature existing technology, so it will not be elaborated here.

[0035] Flexible mattresses 19 are installed on the end faces of the leg support seat 71, the hip support seat 72 and the upper body support seat 73. The support plate 61 is arranged above the flexible mattress 19 on the same side, which can improve the comfort of personnel when lying flat.

[0036] The operating principle of the present invention is described as follows: When the bone density of the person to be predicted is initially detected, the medical staff guides the person to lie above the leg support 71, the hip support 72 and the upper body support 73, with the hip above the hip support 72, the upper body above the upper body support 73, and the legs above the leg support 71. Subsequently, the person to be predicted is guided to keep the legs together, and the linear movement module 18 is controlled by the computer to work. The linear movement module 18 can drive the U-shaped plate 4 to move along the leg support 71. When the footrest 20 moves to the position of the feet of the person to be predicted, the computer controls the linear movement module 18 to stop working, and the person is guided to put the legs into the corresponding U-shaped leg supports 5 respectively. Since the legs of the person to be predicted are spread apart to both sides, the legs will tilt to one side. At this time, under the action of the legs, the U-shaped leg supports 5 will deflect to one side synchronously. Then, the person to be predicted is guided to relax the whole body (the feet of the person to be predicted need to contact and abut against the footrest 20). Next, the electromagnetic clutch 62 and the encoder 65 are started by the computer. The static disk of the electromagnetic clutch 62 will attract the moving disk through electromagnetic force, making the moving disk fixed relative to the static disk. At this time, the U-shaped leg support 5 cannot rotate through the rotating shaft 63. Then, the encoder 65 sends the angle information of the rotating shaft 63 at this time to the computer, and the computer records and stores this angle information (at the same time, a position sensor is installed on the U-shaped plate 4. After the U-shaped plate 4 moves in place, that is, after the feet of the person to be predicted contact and abut against the footrest 20, the computer can measure the position information of the U-shaped through this position sensor);

[0037] Subsequently, the medical staff can start the dual-energy X-ray detection main body 2 through the computer. The dual-energy X-ray detection main body 2 will sequentially detect the bone density at the lumbar spine and hip of the person. The dual-energy X-ray detection main body 2 emits two different energy X-rays to penetrate the human bones and soft tissues, and uses the difference in the absorption degree of different energy rays by bone minerals to accurately measure the bone density and judge the bone loss situation. At the same time, the computer stores and records this bone density information;

[0038] Among them, when starting the dual-energy X-ray detection main body 2 through a computer, the computer will also control the operation of each pressure detector 76. Since the person to be predicted lies flat on the partition plate 74 of the leg support 71, hip support 72, and upper body support 73, the weight of the person to be predicted will exert pressure on each pressure detector 76 through each partition plate 74. The sum of the pressure values detected by each pressure detector 76 is the total weight value of the patient, and the computer stores and records this total weight value (wherein, since the legs are placed on the U-shaped leg rest 5, and the U-shaped leg rest 5 is installed on the partition plate 74 above the leg support 71 through the support plate 61, the footrest 20, the U-shaped plate 4, and the linear movement module 18, it will not affect the accuracy of the weight detection of the person to be predicted). After calculating the total weight value, the computer will calculate the proportion of the pressure detected by each pressure detector 76 in the total weight value. Since the person to be predicted lies flat on the partition plate 74 of the leg support 71, hip support 72, and upper body support 73, the weight of the person to be predicted is distributed to the pressure detectors 76 at the leg support 71, hip support 72, and upper body support 73. Therefore, by calculating the proportion of the pressure value detected by each pressure detector 76 in the total weight value, the weights of the upper body, hips, and legs can be roughly estimated. By calculating the weights of the upper body, hips, and legs, the pressure borne by the bones of each part can be more accurately evaluated, and then the bone density changes at each position can be judged. Similarly, the computer will store and record the calculated weight proportions of the upper body, hips, and legs;

[0039] After the dual-energy X-ray detection main body 2 finishes working, the medical staff guides the person to be predicted to get out of bed, and then starts the disinfection work through the computer. At this time, the pump 93 will draw out the disinfectant inside the disinfectant storage tank 92 and transport it to the cross tube 82 through the infusion tube 94 and the connecting hose 95. At the same time, each ultrasonic atomizing nozzle 83 works, and the disinfectant can be atomized and sprayed out, so that the disinfectant can be atomized and sprayed onto the footrest 20 and the U-shaped leg rest 5, and then the footrest 20 and the U-shaped leg rest 5 can be disinfected to avoid cross-infection. The disinfection time is 30 seconds;

[0040] Among them, before the patient gets into bed and before the patient gets out of bed, medical staff need to start the pre-support work through a computer. When starting the pre-support work, the machine pump 93 starts to work. At the same time, the shunt electronic control valve 16 is energized and opened, and the infusion electronic control valve 17 is energized and closed. At this time, the disinfectant transported by the machine pump 93 will enter the shunt pipe 15 and then enter the sealed hollow plate 13. Then the disinfectant will enter each cylinder 10 through the liquid inlet hole 14. Under the hydraulic action, each piston 11 will drive the T-shaped support member 12 to move upward, so that the T-shaped support member 12 supports each partition plate 74. After the machine pump 93 works for 1 minute, the machine pump 93, the shunt electronic control valve 16 and the infusion electronic control valve 17 stop working. Since the predicted person may sit on a single partition plate 74 first when getting into bed or getting out of bed, resulting in excessive pressure on the pressure detector 76 at that place, or when the person adjusts their body posture, they apply pressure to the partition plate 74, causing the pressure on a certain pressure detector 76 to be overly concentrated. Therefore, by pre-supporting each partition plate 74 before getting into bed and getting out of bed, the weight pressure of the predicted person and the pressure applied during posture adjustment can be first supported by each T-shaped support member 12. During the process of detecting bone density and weight, the computer controls the shunt electronic control valve 16 to be energized and opened again. Under the pressure of the person lying flat, the disinfectant inside each cylinder 10 and the sealed hollow plate 13 will flow back into the disinfectant storage tank 92, so that the weight of the predicted person lying flat is gradually applied to each pressure detector 76, avoiding damage to the pressure detector 76;

[0041] After the bone density and weight of the predicted person are detected, the osteoporosis condition of the person can be predicted based on the bone density condition, the weight ratios of the upper body, buttocks and legs to the total weight. At the same time, the predicted person can have their bone density detected again after a period of time. Through the change amount of bone density on the front and back sides, the change amount of osteoporosis of the predicted person can be judged, so as to predict the osteoporosis condition of the predicted person next. When the predicted person has their bone density detected again, the medical staff can input the patient information on the computer. At this time, the computer will retrieve the previously recorded encoder 65 angle information and the position information of the U-shaped plate 4, and automatically control the linear movement module 18 to move the U-shaped plate 4 to the previously recorded position according to the position of the U-shaped plate 4. Then the patient lies flat again according to the previous requirements, and the angle information displayed by the current encoder 65 is compared with the previously recorded angle information until the current angle information is the same as the previously recorded angle information. Only then can the medical staff start the current bone density detection, trying to ensure that the body postures of the predicted person are the same during the two bone density detections, so as to improve the comparison accuracy of the two bone densities (where the interval time between the two detections shall not be less than 6 months).

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
