Background

Joint problems are often caused by aging and degeneration (e.g., osteoarthritis), or ligament damage (e.g., sprains and strains), among others. Reduced joint lubrication or loss of cushioning cartilage can lead to joint pain, and joint ligament dysfunction also often leads to movement abnormalities. Orthopedic braces are commonly used to share joint load and may limit abnormal movement of the joint to reduce pain and aid in healing. Since joint healing is a progressive process, patients must regularly visit a physician to examine their injured joint and receive intervention or prescriptions to maintain a normal healing process. However, regularly visiting a doctor is both a time and economic burden for the patient and his or her doctor and other associated medical service providers. Therefore, there is a need to develop a device that can detect signs of inflammation and abnormal motion that is characteristic of joint pathology in a longitudinal manner for guiding the treatment.

SUMMERY OF THE UTILITY MODEL

In view of the above problems of the prior art, it is an object of the present invention to provide an orthopedic support (also called smart support) provided with a lesion detector capable of detecting abnormal conditions (e.g., inflammation) from a body part such as a joint.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an orthopedic support (also known as a wearable device) comprising:

at least one anchor (e.g., an elastic band) for fitting to a body part (e.g., a chest, head, limb, joint, torso, or other limb part);

at least one lesion detector connected to the at least one holder for obtaining biomedical parameters of inflammation or other lesion symptoms. Accordingly, the lesion detector comprises an inflammation detector. The orthopedic support can be assembled on bras, hats, sleeves, clothes, gloves, shoes, insoles, skin patches, trousers, underwear and the like.

As an embodiment, the at least one lesion detector comprises any one or a combination of any of a temperature sensor, a color sensor, a bending sensor, a stretching sensor, a geographical position sensor, a humidity sensor, a motion sensor, a displacement sensor, an acceleration sensor, a gravity sensor, a gyroscope sensor, a pulse sensor, an oxygen saturation sensor, a blood pressure sensor, a tactile sensor for continuously reading measurements from the affected body part.

As an embodiment, the at least one lesion detector includes a first detector for fitting to a first part of the human body and a second detector for fitting to a second part of the human body.

Preferably, the at least one anchor includes a first anchor for fitting to a reference site of the human body, and a second anchor for fitting to an injured site of the human body; the first and second detectors are fitted to the human body by the first and second holders, respectively. For example: the orthopedic brace may include a left knee brace having a first multi-temperature sensor, and a right knee brace having a second multi-temperature sensor; the left knee brace and the right knee brace have the same shape, size and material, while the sensors have the same distribution or location on their respective braces; in use, with the left knee brace attached to a healthy knee of a patient and the right knee brace attached to an injured knee of the patient, temperature measurements can be taken at respective locations of the two knee braces to easily identify, record and analyze higher body temperature data at the injured knee; thus, whether by means of the patient's smartphone or by means of a personal computer wired to the knee brace or to the temperature sensor, the doctor can quickly and reliably identify the recovery, inflammation or any other abnormality of the injured knee by means of the electrical signals from the knee brace. Another example is: the knee brace can be worn on an injured knee alone, embedding a temperature sensor (or an infrared sensor) at a critical position of the knee brace so as to be able to detect temperature; for example, the temperature on the patella and the iliotibial band may be relatively lower than the temperature in other areas around the patella due to the lower vascularity of the area around the patella and the patella's good thermal conductivity, i.e. heat dissipation quickly, so that the temperature on the patella and/or the iliotibial band may be used as a reference temperature, i.e. a reference temperature, and the temperature sensor may be placed in the superior capsule of the patella or the inferior fossa of the patella.

The orthopaedic brace 100 according to this embodiment is worn in use at the knee joint 102 and is fixed by an upper transverse strap 104 and a lower transverse strap 106: upper and lower transverse straps 104 and 106 are sewn to the flexible membrane from opposite directions to equalize the distribution of the torsional forces at the thigh and shin and calf 108 and to maintain the integrity of the flexible membrane of orthopedic brace 100, upper transverse strap 104 being sewn biased to the left (first wing) to pull right thigh 112 to the outside of the right leg and lower transverse strap 106 being sewn biased to the right (fourth wing) to pull right shin and calf 108 to the inside of the right leg.

Since orthopedic brace 100 is worn around the leg, stretch sensors 152,170 provide stretch readings of long top portion 122 and long bottom portion 124, and in particular, the degree of stretch of the quadriceps and gastrocnemius muscles, and stretch sensors 152,170 can detect joint swelling caused by excessive fluid accumulation in or around the joint. For example, knee swelling due to fluid accumulation (knee effusion) can be the result of trauma, overuse injury or underlying disease, knee swelling can cause swelling symptoms, pain and limited range of motion. The stretch sensors 152,170 may also be added on the narrow portion 126 of the flexible diaphragm for more accurate readings.

The stretch sensors 152,170 in this embodiment are silicon rubber stretch sensors, which are flexible capacitors whose change in capacitance is correlated to their geometry according to the parallel plate equation, thereby providing accurate information about the change in shape:

where C is the capacitance of the stretch sensor 152,170, A is the surface area, D is the thickness, ε o is the absolute permittivity, and ε r is the relative permittivity of the dielectric layer. Thus, the capacitance of the stretch sensors 152,170 is proportional to the area of the parallel flexible electrodes and inversely proportional to the distance between the flexible electrode layers. Stretching of the stretch sensors 152,170 will cause changes in both area and thickness, and such deformation will cause a measurable change in capacitance. In this embodiment, a variable tensile resistor may be used instead of the silicone rubber tensile sensor.

The flexible sensor 160 in the orthopaedic brace 100 may detect the range of motion of the knee joint 102, which is typically reduced if there is fluid accumulation in the joint. A flexible sensor 160 is located in the middle of the flexible diaphragm and provides readings regarding the extent of the occlusion (extension and flexion) between the femur and tibia. In this embodiment, the flexible sensor 160 uses switches of thin film sensing technology, allowing mechanical movement and even vibration to be measured. The flexible sensor 160 contains a coated substrate that changes conductivity when bent, and the readings taken from the flexible sensor 160 will be interpreted as electrical signals and associated outputs generated by the integrated circuit.

The infrared sensors 150, 162, 164 in the orthopaedic stent 100 may convert infrared energy into electrical signals, in particular thermal type infrared sensors. The infrared sensors 150, 162, 164 may measure human skin temperature. Infrared sensors, including thermocouples and thermistor bolometers, provide constant sensitivity over a wide range of wavelengths. The wavelength at which the human body has the largest response is 09 to 10 micrometers (μm). Thus, ideally, the infrared sensors 150, 162, 164 should have a constant spectral density in the infrared range of 03 to 20 micrometers (μm).

The thermal imaging cameras 148, 158, 166 in the orthopaedic stent 100 may focus infrared radiation emitted from the skin surface within the field of view onto the infrared sensors 150, 162, 164. The thermal imaging camera is capable of detecting skin temperatures in the range of 23 to 33 degrees celsius, its lens for infrared operation is made of silicon and is anti-reflective coated. The function of the thermal imaging camera 148, 158, 166 is to scan the skin surface and reflect thermal characteristics of the skin onto the infrared sensor 150, 162, 164. Generally speaking, the body temperature rises and the skin turns red in color, so that the thermal imaging camera 148, 158, 166 in combination with the infrared sensor 150, 162, 164 can measure the temperature and color of the skin near the joint.

The stretch sensors 152,170 are connected to an inertial sensor chip IMU 3000216, the IMU 3000216 including three independent vibratable micro-electronic and micro-electromechanical systems (micro electronic and micro electromechanical systems) rate gyroscopic (rate gyroscopic) capable of detecting rotation about the X, Y and Z axes; when the gyroscope is rotated about any sensing axis, the Coriolis Effect will cause vibrations that are detected by the capacitive sensors, and the resulting signals are amplified, demodulated and filtered to produce a voltage proportional to angular velocity. The voltage is digitized using a separate on-chip 16-bit Analog-to-Digital (Analog-to-Digital) to sample each axis. The IMU 3000216 also includes a digital motion processor and I2C serial communication interfaces (SDA and SCL) that provide communication with third party devices, such as accelerometers. The stretch sensors 152,170 in cooperation with the flexibility sensor 160 may detect the range of motion and swelling displacement of the knee joint 102.

The microcontroller 182 and Arduino Uno 212 in the orthopedic support 100 can process the data acquired by the thermal imaging camera 148/158/166, the infrared sensor 150/162/164, the flexible sensor 160, and the tension sensor 152/170 and send the processed data to the rectangular antenna coil 172.

The rectangular antenna coil 172 in the orthopaedic stand 100 has a structure for wireless transmission of signals, the rectangular antenna coil 172 and the reader (the reader is in the mobile device 184, e.g., a smartphone) are inductors coupled to each other by a magnetic field, similar to a voltage transformer; the inductance of the rectangular antenna coil 172 is represented by the following equation:

where d is the average diameter of the coil, K1 is a constant of 2.34, K2 is a constant of 2.75, N is the number of turns, and d is in millimeters and is derived from

Where dout is the coil outer diameter 276 (as viewed from above) and din is the coil inner diameter 278;

if the latter is used, the rectangular antenna coil 172 provides an additional antenna in addition to the Bluetooth Mate Silver 214 chip. The Bluetooth Mate Silver 214, in turn, may provide wireless communication to a user's mobile device (e.g., a smart phone) with a built-in antenna capable of operating in different frequency ranges, such as Wi-Fi, 802.11g, and ZigBee. Thus, the rectangular antenna coil 172 and the Bluetooth Mate Silver 214 can transmit the processed data to the user's mobile device.

Audio speaker 156 in biofeedback 183 may provide audio feedback to the user; in the event that the sensor is unable to take a reading from the user, the algorithm in the microcontroller 182 will send audio information to the audio speaker 156, thereby notifying the user; the audio speaker may also alert and guide the user in performing tasks such as application, maintenance, data collection and diagnostic tasks, and limb actions performed to promote rehabilitation; the trigger and audible output may be modified arbitrarily. The haptic vibration motor 154 provides physical feedback to the user, which can be triggered by physical vibrations, based on the same principles as the audio speaker 156. The light emitting diodes LED1, LED2 provide color feedback to the user. The haptic vibration motor 154, the audio speaker 156, and the light emitting diodes LED1/LED2 together form the biofeedback 183.

In addition, the power source of the orthopedic support 100 in this embodiment may be a button battery or a rechargeable battery, which may be charged by using a non-contact technology in an inductive manner to provide continuous working power for the orthopedic support 100. Based on the above principle, the state of the knee joint 102 of the leg can be detected by using the orthopedic support 100, and the specific detection result is shown in fig. 6 and 7.

Fig. 6 is a graph 220 of multiple curves measured using the orthopedic stent of the present embodiment, with data from various sensors (corresponding to lesion detectors) in orthopedic stent 100. The y-axis of the graph is the amplitude axis 222, the x-axis is the time axis 224, the vertical arrows in the y-axis direction indicate increasing amplitude, and the horizontal arrows in the x-axis direction indicate increasing time. The chart may be presented on a display screen of a smartphone or on a display screen of a computing server. The graph provides four curves representing a temperature curve 226, a swelling curve 228, a color curve 230, and a range of motion curve 232 (flexion and extension) between the femur and tibia-fibula, respectively. Wherein the temperature profile 226 represents the temperature change around the patella; the swelling curve 228 represents the degree of swelling around the knee 102; the color curve 230 provides the color of the skin around the patella (e.g., normal skin color versus inflamed red skin, the change in skin color being determined by the decrease in wavelength received by the thermal imaging camera); the range curve 232 represents the range of motion of the knee joint 102. The swollen joints inhibit movement, thereby reducing the range of motion, and inflammation causes swelling and increased body temperature around the affected joints, so that, in the inflamed joints, the body temperature increases, the swelling increases, the skin turns red in color, and the range of motion decreases. Collecting, storing and analyzing these data may indicate whether there is inflammation in the knee joint 102, e.g., at time axis x1, four curves show deviation from normal horizontal trend, indicating that the joint begins to swell.

Fig. 7 is a temperature spread graph 240, i.e., a temperature profile for an inflamed patellar fossa group 246, a temperature profile for a control group 244, and a temperature profile for a baseline group 242. In the figure, the x-axis represents time in seconds and the y-axis represents temperature in degrees celsius. Body temperature for baseline group 242 is obtained from the average temperature of subjects without knee trauma and is represented in the upper graph by the solid line or lowest line relative to the temperature axis. The body temperature of the control group 244 was obtained from the average temperature of knee pain patients who were taking anti-inflammatory drugs and is indicated in the upper graph by a dotted line or a middle line with respect to the temperature axis. The temperature curve for the infrapatellar fossa inflamed group 246 is plotted as a dotted line, or as the highest line relative to the temperature axis in the graph. The above temperatures were measured from the oral cavity over a period of time using a digital thermometer. As shown by the time axis in the figure, all three groups begin collecting temperature data at the 1 st second mark, with an initial average temperature of 36.4 degrees celsius; at the 5 th second mark, the three temperature profiles begin to diverge. The aforementioned deviations are due to delays or lags in the sensor and microcontroller 182 processing signals.

From fig. 6 and 7, it can be determined whether there is an abnormal or inflammatory condition in the knee joint 102 of the leg of the user using the orthopedic support 100, and thus, the orthopedic support 100 can be worn on the human body, and can detect signs of inflammation and abnormal movement representing typical joint diseases in a longitudinal manner, thereby having a therapeutic guiding effect.
