DETAILED DESCRIPTION
[0039] With reference to the drawings of the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.
[0040] Please refer to Figures 1 to 8 A bone density examination physical examination cabin, an experience cavity 1, and a space for accommodating both feet formed inside the experience cavity 1, comprising: the experience cavity 1, a support plate 2, and a leg support assembly 5.
[0041] A vertical lifting rod 3 is fixed to the inner side of the experience cavity 1, and the upper end of the lifting rod 3 is rotationally connected to the support plate 2 through a hinge seat 4.
[0042] The support plate 2 is located at the inner bottom of the experience cavity 1 and is used to support the feet of a user.
[0043] The upper end of the experience cavity 1 is fixed with the leg support assembly 5, which is used to fix the legs of a user. The outer side of the leg support assembly 5 is fixed with a knob locking mechanism 6. The upper end surface of the experience cavity 1 is fixed with an adjusting assembly 7. The support plate 2 is linked with the knob locking mechanism 6 and the support plate 2 through the adjusting assembly 7.
[0044] When the support plate 2 bears the pressure change of the heel, the support plate 2 generates rotational displacement around the hinge seat 4. The rotational displacement of the support plate 2 is converted into the rotational movement of the knob locking mechanism 6 through the linkage adjusting assembly 7, so as to realize the automatic switching of the leg support assembly 5 between the locked state and the relaxed state. In the sitting state, the leg support assembly 5 provides stable leg fixation. When standing, the constraint pressure on the legs is reduced, which is conducive to reducing the accidental binding injury caused by the posture conversion.
[0045] When in use, the user's legs are placed in the experience cavity 1, and the user's feet are placed on the upper end of the support plate 2, and at this time the user's legs correspond to the position of the leg support assembly 5, and at this time the legs are placed in the leg support assembly 5 and fixed by the knob locking mechanism 6, and the leg support is locked by the knob locking mechanism 6, and the bottom of the support plate 2 is provided with the lifting rod 3, and the upper end of the lifting rod 3 is rotatably connected with the support plate 2 through the hinge seat 4, when the user changes from a sitting posture to a standing posture, the user's center of gravity moves forward, and the pressure of the heel on the support plate 2 increases, so that the support plate 2 rotates at the hinge, and the driving force of the support plate 2 during rotation drives the adjustment assembly 7 to rotate, and the adjustment assembly 7 is fixedly connected with the knob locking mechanism 6, so that the driving force of the support plate 2 during rotation drives the adjustment assembly 7 and the knob locking mechanism 6 to rotate, so that the leg support changes from a tight state to a loose state, which facilitates the user to change the posture, reduces the pressure of the leg support assembly 5 on the user's legs, and triggers the mechanical linkage through the change of the pressure of the heel on the support plate 2, which conforms to the natural behavior mode of the human body, can reduce the restriction of the leg support assembly 5 on the legs when the patient adjusts from a sitting posture to a standing posture, and automatically triggers the mechanical interlocking mechanism through the change of the pressure of the heel, so that the leg support state is synchronously linked with the change of the human body posture, and the dynamic adjustment of the supporting strength of the leg support assembly 5 is realized based on the natural center of gravity migration of the human body, so as to meet the supporting requirements in different postures.
[0046] Please refer to Figures 6 to 7 The lifting rod 3 comprises a telescopic rod 31 and a base 32, and the bottom surface of the experience cavity 1 is fixedly connected with the base 32, and the telescopic rod 31 is slidably connected in the base 32.
[0047] When the user's feet exert vertical load, the support plate 2 drives the telescopic rod 31 to move vertically downward along the inner wall of the base 32, and dynamically adjusts the relative height between the support plate 2 and the leg support assembly 5, when the user places both feet on the support plate 2, the support plate 2 and the telescopic rod 31 are inwards contracted by the weight of the feet, so as to increase the gap between the support plate 2 and the leg support assembly 5, so as to increase the distance between the feet and the legs, so as to adapt to users with different leg lengths, and the length of the rotating shaft of the hinge seat 4 can be increased, and the length of the side wall parallel to the axis of the lifting rod 3 can be increased, the contact area of the lifting rod 3 and the hinge seat 4 is increased, the stability of the lifting rod 3 supporting the support plate 2 is increased, or a plurality of lifting rods 3 and hinge seats 4 are arranged, and the rotating shafts of the plurality of hinge seats 4 are concentrically arranged, so as to increase the stability of the lifting rod 3 supporting the support plate 2.
[0048] Please refer to Figures 1 to 3 The upper end surface of the support plate 2 is fixedly connected with a plurality of supporting springs 8, the upper end surface of the supporting spring 8 is fixedly connected with a supporting plate 81, and the upper end of the supporting plate 81 is fixedly connected with a foot fixing assembly 9.
[0049] In use, the user places the feet between the supporting plate 81 and the foot fixing assembly 9, and the heels and soles of the feet are located on both sides of the rotation center of the supporting plate 2, at this time, the position of the foot fixing assembly 9 corresponds to the feet of the user, and a plurality of supporting springs 8 are arranged between the supporting plate 81 and the supporting plate 2, when the pressure applied by the feet above the supporting plate 81 is removed, the elastic force of the supporting springs 8 drives the supporting plate 81 to move upward, thereby reducing the pressure of the supporting plate 81 on the air bag pad 93, so that the air bag does not have to be in an inflated state all the time, which is beneficial to increase the service life of the air bag.
[0050] Please refer to Figure 1 , Figure 2 , Figures 4 to 6 The foot fixing assembly 9 includes elastic ropes 91, air bag strips 92 and an air bag pad 93, the air bag pad 93 is fixed between the supporting plate 2 and the supporting plate 81, and the upper end of the supporting plate 81 is fixed with a plurality of elastic ropes 91, the side of the supporting plate 81 close to the plurality of elastic ropes 91 is fixed with the air bag strips 92, and the air bag pad 93 and the plurality of air bag strips 92 are communicated, so that when the supporting plate 81 presses downward on the air bag pad 93, the gas in the air bag pad 93 enters the air bag strips 92, the air bag strips 92 are inflated downward to make the lower end of the air bag strips 92 fit the feet of the user and fix the feet of the user, and if the user feels uncomfortable due to long-time pressure on the feet, the air bag strips 92 can be slightly lifted upward to make the gas in the air bag strips 92 flow back to the air bag pad 93, thereby reducing the pressure of the air bag strips 92 on the feet, so that the user can freely adjust the pressure of the air bag strips 92 on the feet during the detection process. Since the user actively adjusts during the adjustment process, the feet will not shake in a large range under the conscious control of the feet, so even if the control force of the air bag on the feet is weakened at this time, the feet will not shake.
[0051] Please refer to Figure 1 The side wall of the experience cavity 1 is provided with an outlet 101 capable of accommodating the legs to go in and out, the leg supporting assembly 5 includes a supporting cylinder 51, a fixing cylinder 52 and a woven belt 53, the supporting cylinder 51 is arranged through the upper end of the experience cavity 1, the fixing cylinder 52 is hinged to the side wall of the outlet 101 through a connecting layer 521, the shapes of the supporting cylinder 51 and the fixing cylinder 52 are matched, and the woven belt 53 is fixed to the outer side of the supporting cylinder 51.
[0052] Please refer to Figure 1 The fixing cylinder 52 is woven from fiber material, and the connecting layer 521 is a cloth strip made of polyester fiber and spandex blended material, the lower end of the cloth strip is bonded to the side wall of the outlet 101, and the upper end of the cloth strip is sewn to the fixing cylinder 52;
[0053] In use, after the experience cavity 1 is placed on the user's leg, the fixed cylinder 52 is rotated at the connecting layer 521, so that the fixed cylinder 52 moves towards the side close to the support cylinder 51, until the support cylinder 51 and the fixed cylinder 52 are buckled and enclosed into a cylindrical shape. At this time, the woven belt 53 outside the support cylinder 51 is wound around the fixed cylinder 52 and clamped with the knob locking mechanism 6 on the other side of the support cylinder 51, so that the user's leg can be closely attached to the fixed cylinder 52. At the same time, the material of the fixed cylinder 52 is a fiber material, which can deform during the traction of the woven belt 53, so that the fixed cylinder 52 can be attached to the user's leg to reduce the shaking of the user's leg during detection. At the same time, the connecting layer 521 is made of a cloth strip of polyester fiber and spandex blended material. Compared with directly sewing the fixed cylinder 52 at the outlet 101, the wear of the fixed cylinder 52 and the outlet 101 can be reduced, thereby increasing the service life of the fixed cylinder 52. In some cases, such as children or people who cannot maintain a fixed posture for a long time (such as people with hyperactivity disorder), the fixed cylinder 52 can be made of hard plastic material to increase the restriction of the fixed cylinder 52 on the user's leg and reduce the error caused by the user's shaking leg. At this time, since the connecting layer 521 is still a flexible material, the fixed cylinder 52 can still rotate even if the fixed cylinder 52 is made of hard plastic material.
[0054] In some embodiments, the fixed cylinder 52 and the outlet 101 are connected by a rotating shaft, which can also make the fixed cylinder 52 rotate, but requires corresponding shaft holes and installation shafts to increase the complexity of the structure and increase the risk of rotating shaft jamming.
[0055] Please refer to Figures 4 to 5 , the two support cylinders 51 are fixed with knob locking mechanisms 6 on the side close to each other. The free end of the woven belt 53 is provided with a clamping groove 531. The knob locking mechanism 6 includes a knob 61, a stud 62 and a nut seat 63. The inner cavity of the support cylinder 51 away from the fixed end of the woven belt 53 is provided with a nut seat 63. The inner side of the nut seat 63 is threadedly connected with a stud 62, and the end of the stud 62 away from the nut seat 63 is coaxially provided with a knob 61.
[0056] The shape of the clamping groove 531 is long strip, after the fixing cylinder 52 is buckled on the outside of the supporting cylinder 51, the stud 62 on the knob 61 is penetrated through the clamping groove 531 in the installation stage, and is tightened on the nut seat 63, the position between the woven belt 53 and the stud 62 is adjusted, the fixing cylinder 52 is fitted with the leg of the user, the leg of the user is fixed in the leg supporting assembly 5, at this time, the knob 61 is rotated to make the nut seat 63 move to the side close to the knob 61, and then the woven belt 53 is fixed by the friction force applied by the nut seat 63 and the knob 61, the woven belt 53 can be fine adjusted according to the leg circumference of the user, the fixing cylinder 52 is fixed by rotating the knob 61, which is beneficial to improve the convenience of operation, and the supporting cylinder 51 and the fixing cylinder 52 can be buckled by the thread cooperation between the stud 62 and the nut seat 63, and the leg of the user is fixed by the supporting cylinder 51 and the fixing cylinder 52.
[0057] Please refer to Figure 2 、 Figures 7 to 8 , the upper end of the experience cavity 1 is fixed with the adjusting assembly 7, and the adjusting assembly 7 comprises a supporting seat 71, a rotating rod 72, a connecting rod 73 and a rotating seat 74, the supporting seat 71 is fixed between the two leg supporting assemblies 5, and the upper end of the supporting seat 71 is rotatably connected with the rotating rod 72, the two ends of the rotating rod 72 are respectively fixedly connected with the knobs 61 on the two knob locking mechanisms 6, the upper end of the supporting plate 2 is fixed with the rotating seat 74, and the connecting rod 73 is arranged between the rotating rod 72 and the rotating seat 74.
[0058] Please refer to Figure 1 and Figure 7 , the two ends of the rotating rod 72 are symmetrically provided with bending parts, and the two ends of the connecting rod 73 are annular, the two ends of the connecting rod 73 are respectively sleeved on the bending parts of the rotating rod 72 and the rotating shaft on the rotating seat 74.
[0059] The upper end surface of the experience cavity 1 is provided with a guide groove 102, and the position of the guide groove 102 corresponds to the position of the connecting rod 73, and the movement path of the connecting rod 73 is the same as the movement path of the guide groove 102.
[0060] When in use, the two ends of the connecting rod 73 are respectively sleeved on the bent part of the rotating rod 72 and the rotating shaft of the rotating seat 74, at this time, a crank connecting rod mechanism is formed between the support plate 2, the connecting rod 73, the support seat 71 and the rotating rod 72, when the user changes the posture, the user's heel exerts a downward force on the support plate 2, due to the imbalance of the force on the palm part and the heel part of the support plate 2, the heel placing part of the support plate 2 rotates downward, thereby driving the rotating seat 74 to move downward, and further driving the rotating rod 72 to rotate through the connecting rod 73, at this time, the rotating force of the rotating rod 72 drives the knob 61 to rotate, thereby changing the knob 61 from the locked state to the loose state, and the friction between the knob 61 and the woven belt 53 is weakened during the rotation, thereby weakening the restraining force of the leg supporting assembly 5 on the leg, when the user detects the bone density in the negative pressure state, the safety during the action conversion is improved, and the rotating rod 72 is located outside the experience cavity 1, even if the crank connecting rod mechanism between the support plate 2, the connecting rod 73, the support seat 71 and the rotating rod 72 reaches the dead point when the support plate 2 rotates, it can be adjusted from the outside by hand, of course, in some embodiments, the knob locking mechanism 6 is separated from the support plate 2, when standing is needed, the locked state of the knob locking mechanism 6 needs to be released first, and then the standing action is performed, but the user is easy to forget to release the locked state of the knob locking mechanism 6, thereby causing falling down.
[0061] Since all actions are completed before getting up in this process, falling down caused by unstable bottom support is reduced, and after the knob locking mechanism 6 weakens the restraint on the leg, the remaining getting-up action is completed, at this time, the side of the support plate 2 close to the heel is in contact with the bottom surface of the experience cavity 1, at this time, a triangular structure is formed between the support plate 2, the bottom surface of the experience cavity 1 and the lifting rod 3, at this time, standing can increase the stability of the support plate 2 on the foot support.
[0062] First embodiment
[0063] Please refer to Figures 1 to 8 The side of the support plate 2 away from the support cylinder 51 is fixed with a radiation source 10, the receiving unit and the control unit of the x-ray detection device are integrated on the upper inner wall of the experience cavity 1, and the radiation source 10 is located above the support plate 2, the scanning area of which is opposite to the foot of the patient, and since the radiation source 10 is located above the support plate 2, it can rotate with the support plate 2, so that when the user changes the body state, the radiation source 10 is always aligned with the patient's foot, so that the radiation source 10 always irradiates the patient's foot when the user changes the body state, and irradiates the user's foot throughout the process, so as to record the microstructure change of the bone in the dynamic weight-bearing state.
[0064] It should be noted that the x-ray detection technology is prior art, and its working principle and use method are known, so it is not necessary to repeat it.
[0065] Second embodiment
[0066] Please refer to Figure 9 The upper end of the supporting plate 81 is provided with the ultrasonic probe 11, and the ultrasonic probe 11 is located directly below the heel of the patient;
[0067] When the user puts his foot on the supporting plate 81 after applying the coupling agent, the heel of the user is located directly above the ultrasonic probe 11, the ultrasonic probe is connected with the receiving unit and the control unit through the wire, and then the equipment is started, the probe emits high-frequency ultrasonic waves to penetrate the calcaneus, the receiving probe captures the sound wave signal after penetrating the bone, so as to detect the bone density at the heel. When the user's posture changes, the ultrasonic probe 11 is always in contact with the patient's foot, so that the ultrasonic probe 11 always irradiates the patient's foot when the user's posture changes, and irradiates the user's foot throughout the process, so as to record the microstructure changes of the bone under dynamic weight-bearing state.
[0068] It should be noted that the ultrasonic detection technology is prior art, and its working principle and use method are known, so it is not necessary to repeat them.
[0069] The bone density examination examination cabin provided by the application will be further described in combination with the drawings and embodiments.
[0070] In use, the fixed cylinder 52 is rotated along the connecting layer 521, so as to open the outlet 101 on the experience cavity 1, the user places his foot between the supporting plate 81 and the foot fixing assembly 9, and the heel and the sole of the foot are located on the two sides of the rotation center of the supporting plate 2. At this time, the user can sit on a sofa or a chair, and use the gravity of the foot to drive the supporting plate 81 to move to the side close to the supporting plate 2, so as to compress the gas in the air bag pad 93 through the supporting plate 81, move the gas in the air bag pad 93 to the air bag strip 92, and make the air bag strip 92 expand outward. After the air bag strip 92 expands, it presses the instep of the patient, and fixes the foot of the patient, and then the leg of the patient is fitted into the supporting cylinder 51, until the supporting cylinder 51 and the fixed cylinder 52 are buckled and enclosed into a cylindrical shape. At this time, the woven belt 53 outside the supporting cylinder 51 is clamped outside the threaded column 62 by passing through the fixed cylinder 52, and then the knob 61 is rotated to make the knob 61 tightly screwed outside the woven belt 53. At this time, the knob locking mechanism 6 is in a tightening state, so as to make the leg of the user and the fixed cylinder 52 fit, so that the fixed cylinder 52 can fit on the leg of the user;
[0071] When it is necessary to detect the bone density in the weight-bearing state, the patient is changed from a sitting position to a standing position, at this time the heel exerts a downward force on the support plate 2, due to the imbalance of the force on the support plate 2 between the palm part and the heel part, the heel placement part on the support plate 2 rotates downward, thereby driving the rotating seat 74 to move downward, and then driving the rotating rod 72 to rotate through the connecting rod 73, at this time the rotating force of the rotating rod 72 drives the knob 61 to rotate, thereby changing the knob 61 from the locked state to the loose state;
[0072] During use, the ray source 10 is located above the support plate 2, and its scanning area is directly opposite the patient's foot, and at the same time, since the ray source 10 is located above the support plate 2, it can move with the support plate 2, so that when the user's body posture changes, the ray source 10 is always aligned with the patient's foot.
