Description
Technical Field
The present invention relates to a joint function sensing system. Still further, the present invention relates to a joint function sensing device for use in the joint function sensing system.
Background
Rehabilitation therapy restores normal function to one or more parts of the body. The goals of joint rehabilitation therapy are: repair joint function after joint injury, invasive treatment and surgery. Such conditions requiring rehabilitation therapy include: neuromuscular injury, musculoskeletal injury, degenerative diseases, joint replacement surgery, repair of fractured arms or legs, or arthroscopic knee and hip surgery (arthrograpic surgery).
Joint orthoses (joint orthoses) are commonly used for jointsIn joint rehabilitation treatment, the joint movement is assisted and the joints are protected. The joint orthosis may be a joint brace or a joint splint. Among the joint orthoses available on the market that assist joint rehabilitation, one of them is a joint brace. EPO, manufactured by Breg, IncTMPost-Op Knee Brace is a Post-operative Knee Brace with adjustable adhesive patches to conform to various sizes of legs. EPOTMThe Post-Op Knee brake includes an angular lock having a plurality of flexion and extension points to limit Knee motion, and at least two sets of support members extending from the hinge and attached to the patient's legs. During the rehabilitation treatment process of a patient wearing the knee joint support, a rehabilitation specialist and a doctor can use the buckling and straightening positioning points on the angle locker.
After the knee brace is worn by the patient, the rehabilitation specialist and physician will need to examine the movement of the knee to assess the efficacy of the rehabilitation treatment. However, the information of knee movements learned in retrospective interviews and outpatients may be incorrect from what the patient recorded himself. Therefore, there is a need to monitor and analyze knee motion in real time to get accurate information of the knee motion.
In order to obtain information about the condition of the knee, some knee braces may incorporate sensors. Mavroidis, c. et al (Mavroidis, c., Nikitczuk, j., Weinberg, b., Danaher, g., Jensen, k., Pelletier, p., & Pavone, R. (2005). Smart portable rehabilitating device, journal of neuroengineering and Rehabilitation,2(1),18.) propose a knee stent in combination with a current stimulation module, sensors and feedback mechanism. The current stimulation information is transmitted to a control box to monitor the muscle activity of the knee and provide additional current stimulation at the appropriate time.
In addition, X4TMSmart Brace is a supportive knee Brace that can monitor knee motion instantaneously. X4TMSmart Brace is equipped with a sensor to monitor the flexion and extension of the knee, a transmission module to transmit a series of flexion and extension information to an external device, which may be a Smart phone or a computer. The external device may then store the information asFor future evaluation.
Solution and X4 provided by Mavroidis, CTMSmart brake integrates a sensor into the knee Brace. However, for a large patient or a pediatric patient, if the knee brace with the sensor is not fit, the knee brace with the sensor is not suitable for the patient. Also, if a patient wants to change from a sensorless knee brace to wear the sensorless knee brace, the patient may need to purchase a new sensorless brace and discard the old knee brace. All of which may increase the cost of the patient's knee undergoing rehabilitation therapy.

The button 142 extends through the top housing aperture 1412 of the top housing 141 and the user or subject can press the button 142 to interact with the internal components, preferably the control module 150. The pivot shaft includes the central portion 121 coupled to the top housing opening 1411 of the top housing 141 and a distal portion 122 extending from the central portion 121.
Fig. 6 shows another exploded view of some components of the joint function sensing device 100, in accordance with one embodiment of the present invention. In fig. 6, the top case 141, the side case 143, and the bottom case 144 have been omitted to show details of other elements. The central connection 1211 is complementary to a control module hole 151 located at a center of the control module 150. The distal portion 122 includes a distal prong 1221 adjacent an edge of the top case 141 and complementary in structure to the plurality of band-receiving members 1311 of the band 131. Similarly, the band 131 also includes a band fork 1312 that is also structurally complementary to a band base receptacle 1321 of the band base 132. The watch band base 132 further includes a band base attachment means 1322 such that the watch band base 132 is detachably attached to the support member 220a or 220b of the accessory 200.
The band fork 1312 of the band 131 may have 2 protrusions and the band base accommodating part 1321 of the band base 132 may have 2 recesses for accommodating the protrusions of the band fork 1312, as shown in fig. 6. Conversely, the band fork 1312 of the band 131 may have 2 recesses and the band base accommodating part 1321 of the band base 132 may have 2 protrusions to be inserted into the recesses of the band fork 1312.
Fig. 7 is a side view of the components of fig. 6. The distal portion 122 has a curved shape in which the distal forked member 1221 is bent toward the band module 130. The central portion 121 of the rotating shaft 120 further includes a central shaft 1212 extending downward from the central connecting structure 1211 to connect with the control module 150. The central shaft 1212 can couple with the control module bore 151 of the control module 150. Also, the central shaft 1212 may be configured to pass through the control module bore 151. The first sensor 170 is coupled to the central shaft 1212 of the rotating shaft 120 and is capable of being communicatively coupled with the control module 150. Specifically, the first sensor 170 may be mounted to an upper side or a lower side of the control module 150. The central shaft 1212 is a rotation center of the rotation shaft 120. When the rotating shaft 120 is rotating, the first sensor 170 coupled to the central shaft 1212 monitors a rotation angle of the rotating shaft 120, and the rotation angle information is transmitted to a controller (not shown) of the control module 150. The controller can process the rotation angle information and transmit the information to a computing element. When the first joint function sensing system 1 is worn by the subject and the rotation shaft 120 rotates along with the joint movement of the subject, the rotation angle represents a flexion or extension movement of the joint, so that the physician or the rehabilitation specialist can evaluate the rehabilitation progress or pathological condition of the joint. When the first joint function sensing system 1 is worn by the subject and the rotation shaft 120 rotates with the joint movement of the subject, the user can also assess the exercise ability of the subject or perform a functional diagnosis on the subject. Therefore, the joint function sensing device 100 can measure and analyze joint movement in real time by the first sensor 170 and the control module 150.
The computing element may be a part of the control module 150, or another device and not contact the auxiliary device 200 or the joint function sensing device 100. The computing device may be a Central Processing Unit (CPU), a Microprocessor (MPU), or a device having the CPU or the MPU. Preferably, the computing element is a mobile device.
The control module 150 includes the controller, a switch (not shown), and a second sensor (not shown). The switch is connected to the button 142, and the user can activate or deactivate the joint function sensing device 100 by pressing the button 142. The button 142 can also be coupled to other built-in functions in the control module 150, such as mode switching or recording functions. When the joint function sensing device 100 is attached to the auxiliary device 200, the second sensor on the control module 150 measures an inclination angle of the joint function sensing device 100. The oblique angle is an angle between the auxiliary device 200 and the geocentric in the coronal plane, while the aforementioned straightening and flexing of the auxiliary device 200 is an activity in the sagittal plane.
In fig. 6 and 7, the joint function sensing device 100 includes 2 watchbands 131, but the joint function sensing device 100 may include only one watchband 131. The number of the bands 131 may be 1 to 6. The more watchbands 131, the longer the watchband module 130. This setting allows the watchband module 130 to have an adjustable length. Since the auxiliary devices may be different in shape and size, the joint function sensing device 100 having an adjustable length can be mounted on auxiliary devices having different shapes and sizes. The adaptability of the device 100 to various auxiliary devices allows the physician or the rehabilitation specialist to prescribe a flexible rehabilitation treatment plan for the subject. If the user wants to obtain the rotation angle information of the joint from the device 100 provided in the present invention, the subject can still wear their own original auxiliary device, such as a knee brace or a hip brace, and attach the device 100 to the original auxiliary device. Thus, the subject is required to incur significantly less equipment costs than purchasing a completely new accessory device, and the fit when the subject wears the original device is higher than when the subject is converted to a completely new accessory device.
Figures 8A-8D illustrate a first portion of an installation process of the joint function sensing device 100 in accordance with one embodiment of the present invention. In fig. 8A, a heart finder 180 is placed on the hub 210. The heart finder 180 may be a piece of cardboard or plastic with edges that conform to the shape of the hinge 210. The heart finder 180 includes a heart finder opening 181 and a bottom surface, and the heart finder opening 181 has a complex shape formed by a rectangle and 2 semicircles. Thus, the seeker opening 181 has a long axis. When placing the heart finder 180 on the hinge 210, both ends of the long axis of the heart finder opening 181 must be aligned with the directions of the support members 220a and 220b of the auxiliary device 200.
In fig. 8B, the fixing base 110 has the same shape as the heart finder opening 181. When the fixing base 110 is placed on the heart finder opening 181, the user must press the fixing base 110 to make a bottom surface of the fixing base 110 having adhesive adhere to the hinge 210. In fig. 8C, the modular entity (as shown in fig. 5) is combined with the holder 110. Specifically, the bottom housing 144 and the mounting base 110 are integrally formed. In fig. 8D, the modular assembly is integrally mounted on the hinge 210, and the heart finder 180 can be located under the bottom housing 144. In fig. 8D, the heart finder 180 can be removed first and then the bottom housing 144 and the fixing base 110 of the modular assembly are combined.
FIGS. 9A-9D illustrate a second portion of an installation process of the joint function sensing device 100 in accordance with one embodiment of the present invention. In fig. 9A, the distance L between the pivot shaft 120 and the support member 220b can be measured by the user to determine the number of the bands 131 coupled to the pivot shaft 120. The watchbands 131 and the watchband base 132 are provided in fig. 9B and 9C. More than one wristband 131 may be required to lengthen the wristband module 130. The bands 131 are first coupled to the distal portion 122 of the pivot shaft 120, and the band base 132 is then coupled to one of the bands 131 in FIG. 9D. The watchband base 132 includes a bottom side with adhesive. In FIG. 9D, the strap base 132 is pressed by the user, and the adhesive on the underside allows the strap base 132 to be attached to the support member 220 b. This completes the process of mounting the joint function sensing device 100 to the auxiliary device 200.
FIG. 10A illustrates a straightening motion of the first joint function sensing system 1, in accordance with one embodiment of the present invention. In fig. 10A, the angle between the support members 220A and 220b is 0 degrees. A straightening angle of 0 degrees can be sensed by the first sensor 170 in the joint function sensing device 100.
FIG. 10B illustrates a flexion of the first joint function sensing system 1 according to an embodiment of the present invention. In fig. 10B, the support member 220a is bent 90 degrees. When the subject wears the first joint function sensing system 1, the bending of the support element 220a is most likely due to the flexion of the subject's leg. The rotating shaft 120 has been rotated and the housing 140 is stationary relative to the hinge 210 and does not change direction. A flexion angle of 90 degrees can be sensed by the first sensor 170 in the joint function sensing device 100 and transmitted to the computing element. The user or the computing element can then compare the flexion angle and the extension angle to assess the function of the joint.
FIG. 11 illustrates a second joint function sensing system 2 in accordance with one embodiment of the present invention. The second joint function sensing system 2 includes an auxiliary device 300 and the joint function sensing device 100 that can be detachably attached to the auxiliary device 300. The auxiliary device 300 and the auxiliary device 200 may have different sizes and shapes, however, the joint function sensing device 100 is detachably attached to both the auxiliary device 300 and the auxiliary device 200. The joint function sensing device 100 can be mounted to different auxiliary devices, thus reducing the cost of joint rehabilitation for the subject, since the subject does not need to exchange another auxiliary device when using the joint function sensing device 100 of the present invention. The modular design of the joint function sensing device 100 also provides greater flexibility to the subject as it can be mounted to auxiliary devices having different sizes and shapes.
Fig. 12 shows the auxiliary device 300 according to an embodiment of the invention. The aid 300 is wearable by the mammalian subject and corresponds to the joint of the mammalian subject and a body part of the mammalian subject adjacent to the joint. The joint may be an ankle joint, a knee joint, a hip joint, a shoulder joint, an elbow joint, or a wrist joint. The body part adjacent to the joint may be a foot, leg, hip, shoulder, arm or hand. The assistance device 300 may assist in the movement, such as straightening, flexing, or rotating, of a joint and body parts adjacent to the joint. The auxiliary device 300 is an ankle joint orthosis when the joint is the ankle joint, a knee joint orthosis when the joint is the knee joint, a hip joint orthosis when the joint is the hip joint, a shoulder joint orthosis when the joint is the shoulder joint, or a wrist joint orthosis when the joint is the wrist joint. The joint orthosis may be a joint brace or a joint splint. Preferably, the auxiliary device 300 is a knee brace.
The auxiliary device 300 includes a hinge 310 to which the joint function sensing device 100 is detachably attached, and 2 support members 320a and 320b coupled to an upper portion and a lower portion of the hinge, respectively. The support members 320a and 320b are fixed elements of the auxiliary device 300 and may include a plurality of strips or bands. The strips or bands of the support elements 320a and 320b may be elongated to conform to the shape of the body parts adjacent to the joint. The support members 320a and 320b may be attached to the body parts adjacent to the joint by means of nylon buttons, buttons or straps, so that the aid 300 can be securely worn by the mammalian subject. The support members 320a and 320b may also be constructed of soft, semi-rigid, or rigid materials. These materials are durable and can withstand prolonged contact with the skin of the subject. The hinge 310 provides a straightening or flexing motion within the auxiliary device 300. When the assistive device 200 is worn by the mammalian subject, the hinge 210 aligns with the joint. Thus, when the mammalian subject bends the joint, the assistive device 300 will also be bent, and the support elements 320a and 320b will not be in line as shown in fig. 12.
FIG. 13 illustrates a third joint function sensing system 3 in accordance with one embodiment of the present invention. The third joint function sensing system 3 includes an auxiliary device 400 and the joint function sensing device 100 that can be detachably attached to the auxiliary device 400. The auxiliary device 400, the auxiliary device 300 and the auxiliary device 200 may have different sizes and shapes, however, the joint function sensing device 100 is detachably attached to the auxiliary device 400, the auxiliary device 300 and the auxiliary device 200. Specifically, in the third joint function sensing system 3, the joint function sensing device 100 is attached to the auxiliary device 400 by 3 watchbands 131 and watchband bases 132; in the second joint function sensing system 2, the joint function sensing device 100 is attached to the auxiliary device 300 by 2 watchbands 131 and watchband bases 132. This variable wristband design enables the joint function sensing device 100 to have different lengths and thus be attached to auxiliary devices having different shapes and sizes.
Fig. 14 shows an external view of a fourth joint function sensing system 4 worn by the subject, in accordance with an embodiment of the present invention. The fourth joint function sensing system 4 includes an auxiliary device 500 and the joint function sensing device 100 that can be detachably attached to the auxiliary device 500. The supplemental device 500 can be worn on a different body part, and the body part can be different from the body part on which the supplemental devices 400, 300, and 200 are worn. The auxiliary device 500 may be an orthosis suitable for the elbow joint. The aid 500 is worn by the subject and corresponds to the shape of the elbow joint and an arm of the subject.
Fig. 15 shows an external view of a fifth joint function sensing system 5 worn by the subject, in accordance with an embodiment of the present invention. The fifth joint function sensing system 5 includes an auxiliary device 600 and the joint function sensing device 100 detachably attachable to the auxiliary device 600. The supplemental device 600 can be worn on a different body part, and the body part can be different from the body part on which the supplemental devices 500, 400, 300, and 200 are worn. The auxiliary device 600 may be an orthosis suitable for the ankle. The assisting apparatus 600 is worn by the subject and corresponds to the shape of the ankle, a leg and a foot of the subject. Fig. 14 and 15 demonstrate the elasticity of the joint function sensing device 100: it may be mounted to an auxiliary device adapted for the elbow joint or the ankle joint.
When the first joint function sensing system 1, the second joint function sensing system 2 or the third joint function sensing system 3 is worn on the knee joint of a bipedal mammal subject, the rotation angle of the rotation shaft 120 may be 0 to 180 degrees. The rotation angle of the rotation shaft 120 may also be 0 to 180 degrees when the fourth joint function sensing system 4 is worn to the elbow joint or when the fifth joint function sensing system 5 is worn to the ankle joint. However, when the joint function sensing device 100 is attached to another auxiliary device that can be worn by another joint of the bipedal walking mammalian subject, or to another auxiliary device that is worn by another subject having a joint that can rotate 360 degrees, the rotation angle of the rotation shaft may be 0 degrees to 360 degrees. The human shoulder joint can be rotated 360 degrees, so that the rotation axis 120 can be rotated 0 to 360 degrees when the joint function sensing device 100 is attached to a shoulder joint orthosis and the above combination is worn by the shoulder joint of a human subject.
