Description

Technical Field

[0001] The invention belongs to the technical field of medical rehabilitation devices, and in particular relates to an auxiliary rehabilitation shoulder support vest capable of monitoring shoulder dislocation. Background Art

[0002] The shoulder joint is the joint that is most prone to dislocation in the body and is also one of the most common diseases in orthopedics. There is still a high probability of recurrence after rotator cuff repair and shoulder joint repair surgery. At present, the means of postoperative rehabilitation of the shoulder joint are mainly to restore the stable structure of the shoulder joint, provide external support and stimulation, and strengthen the strength of the rotator cuff muscles. The strength of the rotator cuff muscles is restored through bandage fixation or mechanical fixation, patting the rotator cuff muscles, and simple strength exercises. The rehabilitation stage mainly uses mechanical fixation or wearable flexible rehabilitation braces, which do not fully take into account the problem of limited shoulder joint mobility in patients, and cannot effectively monitor the dislocation status of the shoulder joint without restriction to intuitively display the patient's shoulder joint status.

When the patient's shoulder joint is dislocated, the patient's arm will move down relative to the body. At this time, the magnet on the magnetic bandage will approach the monitoring circuit board, and the corresponding magnetic induction monitoring circuit of the monitoring circuit board will detect the approach of the magnet and emit a prompt light when sensing the magnetic field of the magnet to indicate that the shoulder joint is dislocated and repositioning treatment is needed.

[0026] It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0027] It should be understood that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments can be understood according to specific circumstances.

[0028] In the following description, certain details are provided to facilitate a complete understanding of the example embodiments. However, it will be appreciated by those of ordinary skill in the art that the example embodiments may be implemented without these certain details. For example, the system may be shown in a block diagram to avoid obscuring the example with unnecessary details. In other embodiments, well-known processes, structures, and techniques may not be shown in unnecessary detail to avoid obscuring the embodiments.

[0029] Example:

[0030] This embodiment provides an auxiliary rehabilitation shoulder support vest capable of monitoring shoulder dislocation. Figure 1 and Figure 2 As shown, it includes a vest body 1 and a shoulder rest 2, a monitoring circuit board 3 is provided on the waist side of the vest body 1, the shoulder rest 2 is arranged on the shoulder of the vest body 1, and the shoulder rest 2 and the monitoring circuit board 3 are on the same side, a magnetic bandage 4 is sleeved on the arm part of the bottom of the shoulder rest 2, a magnet 5 is provided on the side of the magnetic bandage 4 close to the monitoring circuit board 3, a plurality of groups of cascaded magnetic induction monitoring circuits are provided on the monitoring circuit board 3, and the magnetic induction monitoring circuit is used to detect the approach of the magnet 5 and emit a prompt light when the magnetic field of the magnet 5 is sensed.

[0031] In specific implementation, the patient can wear the vest body 1 and the shoulder rest 2 during the postoperative rehabilitation stage of the shoulder joint, and put a magnetic bandage 4 on the arm, so that under normal circumstances, the magnet 5 on the magnetic bandage 4 is not close to the monitoring circuit board 3 on the vest body 1, and the monitoring circuit board 3 has no prompt. When the patient's shoulder joint is dislocated, the patient's arm will move down relative to the body. At this time, the magnet 5 on the magnetic bandage 4 will be close to the monitoring circuit board 3, and the corresponding magnetic induction monitoring circuit of the monitoring circuit board 3 will detect the approach of the magnet 5, and emit a prompt light when sensing the magnetic field of the magnet 5, to prompt that the shoulder joint is dislocated and repositioning treatment is needed, and each group of magnetic induction monitoring circuits can be arranged at intervals to sense and detect the magnet 5 at different heights.

[0032] Furthermore, the shoulder support 2 is also provided with an electrical stimulation device 8, which can electrically stimulate the patient's shoulder joint to promote the contraction of muscles around the shoulder joint, improve muscle function, restore muscle strength around the shoulder joint, and enhance the dynamic stability of the shoulder joint, thereby achieving the effect of auxiliary rehabilitation treatment. Figure 3 The foldable support table top 11 shown can be opened to place the patient's arms, so as to support the patient's arms and assist the patient's activities and rehabilitation exercises.

[0033] Furthermore, if Figure 4 As shown, the magnetic induction monitoring circuit includes a Hall sensor, a first field effect transistor and a light emitting diode connected in sequence. The Hall sensor is used to output an induced electrical signal to the first field effect transistor when sensing the magnetic field of the magnet 5. The first field effect transistor is used to conduct when receiving the induced electrical signal and control the light emitting diode to emit a prompt light. The magnetic induction monitoring circuit also includes a triode and a second field effect transistor. The triode is an NPN-type triode, and the second field effect transistor is an N-type field effect transistor. The base of the triode is connected to the common connection end of the first resistor and the second resistor, the other end of the first resistor is connected to the output end of the Hall sensor, the other end of the second resistor is grounded, the emitter of the triode is grounded, the collector of the triode is connected to the gate of the second field effect transistor, the source of the second field effect transistor is used to connect to the power supply, and the drain of the second field effect transistor is connected to the magnetic induction monitoring circuit of the next level.

[0034] In specific implementation, the principles of each group of magnetic induction monitoring circuits are consistent. Figure 4Take the magnetic induction monitoring circuit shown as an example: U1 is a Hall sensor, capacitor C5 is a filter bypass capacitor of the power supply, capacitor C1 is an output filter capacitor, and resistor R1 is used as the off resistor of the first field effect tube Q2. The reason for choosing 200K is to consider the loss when Q2 is turned on. Because the battery capacity is limited, not adding resistor R1 will result in failure to turn off Q2. Q2 is a low-voltage NMOS tube, which is used as an electronic switch. By receiving the output electrical signal of the Hall sensor, the light-emitting diode LED behind is controlled to emit light. The turn-on voltage of this first field effect tube Q2 is low, and the size is small, so the Hall sensor can drive it. Resistor R2 is the current limiting resistor of the light-emitting diode. The circuit on the right side of the light-emitting diode is used as a power supply electronic switch to control the subsequent magnetic induction monitoring circuit. When U1 senses the magnetic field, it outputs a low level, so the voltage division of the first resistor R4 and the second resistor R5 cannot turn on the triode Q3, so the second field effect tube Q1 cannot be turned on, and the subsequent magnetic induction monitoring circuit will be powered off and not work. When U1 does not sense the magnetic field, it outputs a high level of 3V. Through the voltage division of the first resistor R4 and the second resistor R5, the middle point is greater than the transistor turn-on voltage of 0.75V, the transistor is turned on, the second field effect tube Q1 is turned on, and the subsequent magnetic induction monitoring circuit is powered and can work normally. In this way, the magnetic induction monitoring circuits at different parts can be used to monitor the following distances of the patient's arm after shoulder dislocation. In addition to voltage division, R5 also has the function of a pull-down resistor to prevent Q3 from being mis-conducted. R4 can be used as a current limiting resistor. The current limiting is to ensure that the current on the transistor is more than the amplification factor, stable in the switching state, and prevent entering the amplification interval. The transistor Q3 uses an NPN transistor, and its main function is a reverse switch to match the output of the Hall sensor U1 with the start of the second field effect tube Q1. If the Hall sensor U1 has a signal output of a high level, Q3 is a common emitter amplifier circuit, which is transformed into an inverter of a digital circuit, low to high, and the functions of R3 and R1 are the same, ensuring the reliable shutdown of the field effect tube. The basic principle of the whole circuit is that the Hall sensor senses the presence of a magnetic field and outputs a low level, which causes the gate of the field effect tube that controls the light-emitting diode to be directly pulled down, and the source of the field effect tube is connected to the power supply. The first field effect tube is directly turned on to light up the light-emitting diode. At the same time, because of the low output level, the transistor behind is turned off. Due to the shutdown of the transistor, the second field effect tube cannot be turned on, and the subsequent magnetic induction monitoring circuit does not receive power and does not work. If the Hall sensor does not detect a magnetic field and outputs a high level, the first field effect tube cannot be turned on, and the light-emitting diode does not light up. At the same time, because of the high level, the transistor is turned on, and the second field effect tube behind is directly turned on to power the subsequent magnetic induction monitoring circuit.

[0035] like Figures 4 to 6As shown, the monitoring circuit board 3 can be provided with a code switch SW1 to adjust the position to control the electrical stimulation device 8, and at the same time, the Hall sensor signal pin is connected to the microcontroller digital input pin, and the microcontroller output pin is connected to the trig pin of the 555 timer U5 to trigger the pulse. The connection between the 555 timer U5 and the electrical stimulation device 8 can be achieved by connecting the wire between the digital output pin and the timer pin, and the control input of the electrical stimulation device 8 is connected to the OUT pin of the 555 timer U5 to receive the pulse signal. The frequency is 50Hz and the pulse width is 400μs.

[0036] Furthermore, if Figure 7 and Figure 8 As shown, the shoulder rest 2 is detachably connected to the vest body 1 through a first Velcro 6, and the shoulder rest 2 is provided with a strap 7, and the strap 7 is used to tie the shoulder rest 2 to the vest body 1. The waist side of the vest body 1 is provided with a second Velcro 9, and the monitoring circuit board 3 is detachably attached to the second Velcro 9. The magnetic bandage 4 is provided with a third Velcro 10, and the magnetic bandage 4 is connected head to tail through the third Velcro 10. The vest body 1 is detachably connected to the foldable support table board 11 through a fourth Velcro 12. The various components are detachably attached through corresponding Velcro, which facilitates the rapid assembly and use or disassembly and maintenance of the corresponding components.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
