[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] like Figure 1-Figure 5As shown, this embodiment proposes a rehabilitation medical wireless calling device with convenient position adjustment, including a support base 31, the support base 31 is connected to an alarm for wireless calling, and the support base 31 is connected to a push switch 36 that can control the activation of the alarm.

[0031] A wireless alarm is an alarm that detects electrical signals transmitted by electromagnetic waves in space. In order to achieve wireless transmission, a wireless channel transmitter and receiver can be added between the detector and the alarm controller. The wireless alarm adopts the conventional and mature GSM wireless telephone alarm, making full use of the public telephone network and the ubiquitous GSM wireless telephone network. The dual networks can be used in conjunction with any automatic dialing alarm system to provide highly reliable signal transmission services to ensure the successful transmission of alarm signals.

[0032] The alarm system utilizes the GSM wireless cellular telephone network text message and voice function platform to complete remote alarm data transmission and control. The system can be set according to the mode set by the medical staff. When the push switch 36 is pressed, the alarm can be controlled to send the alarm signal to the host. After processing, the host sends a short message with the alarm address and category to the pre-set mobile phone number of the medical staff, and automatically dials the pre-set phone number for voice alarm and can monitor the scene, so that hospital staff can be aware of the patient's condition in time.

[0033] The push switch 36 can be specifically a spring switch, which is a commonly used electronic switch device, and its working principle is to control the opening and closing of the circuit by compressing and releasing a spring. The spring switch is usually composed of a fixed contact and a movable contact.

[0034] When no force is applied, the spring switch is in a relaxed state, and the circuit is disconnected between the two contacts. When force is applied to make the movable contact contact the fixed contact, the circuit is closed and current can pass. The elasticity of the spring makes it return to its original state when the force is released, separating the movable contact from the fixed contact and disconnecting the circuit. This realizes the control of the opening and closing of the circuit by applying and releasing force.

[0035] The support seat 31 is rotatably connected to the rotating wheel 35 and the cam 41. The rotating wheel 35 is connected to the support seat 31 through a spiral spring 32. The spiral spring 32 is used for resetting the rotating wheel 35. The rotating wheel 35 is rotatably connected to the claw 42. The claw 42 is connected to the rotating wheel 35 through a fourth spring 43. The cam 41 is provided with a slot 44 for the claw 42 to be inserted into. When the cam 41 rotates, it can touch the press switch 36 to activate the alarm.

[0036] One end of the fourth spring 43 is connected to the rotating wheel 35, and the other end of the fourth spring 43 is connected to the claw 42. When the rotating wheel 35 rotates slowly, the claw 42 and the slot 44 are not in contact under the action of the fourth spring 43. When the rotating wheel 35 rotates too fast, the claw 42 can be inserted into the slot 44 under the action of centrifugal force. At this time, the rotation of the rotating wheel 35 can drive the cam 41 to rotate.

[0037] The cam 41 is located on one side of the push switch 36. In the present application, when the cam 41 rotates, the cam 41 can press the push switch 36. When the button is pressed, the applied force compresses the spring, causing the contacts to close and the circuit to be connected. At this time, the alarm starts working and sends information to the medical staff in a timely manner. When the button is released, the spring returns to a relaxed state, the contacts open, the circuit is disconnected, the alarm stops working, and the device is reset.

[0038] There are two connection methods for the rotating wheel 35. When method one is adopted, the rotating wheel 35 is detachably connected with a pressure rod 5 for supporting the human body. The inner circle of the rotating wheel 35 is fixedly connected with a square rod. The pressure rod 5 is provided with a square hole, and the pressure rod 5 can be inserted into the square rod. The end of the square rod away from the rotating wheel 35 is fixedly connected with a threaded rod, and the threaded rod part is threadedly connected with a nut. By tightening the nut so that the nut and the pressure rod 5 are in contact, the pressure rod 5 and the rotating wheel 35 are detachably connected. Due to the setting of the square rod, when the pressure rod 5 rotates, the rotating wheel 35 can be driven to rotate at the same time.

[0039] When method two is adopted, the rotating wheel 35 is detachably connected to the rope collecting wheel, and the rope collecting wheel is wrapped with a pull rope, and the pull rope is connected to a strap that can be fixed to the human body. The inner circle of the rotating wheel 35 is fixedly connected to a square rod, and the rope collecting wheel is provided with a square hole, and the rope collecting wheel can be inserted into the square rod. The end of the square rod away from the rotating wheel 35 is fixedly connected to a threaded rod, and the threaded rod part is threadedly connected with a nut. By tightening the nut so that the nut and the rope collecting wheel are in contact, the rope collecting wheel and the rotating wheel 35 are detachably connected. Due to the setting of the square rod, when the rope collecting wheel rotates, the rotating wheel 35 can be driven to rotate at the same time.

[0040] Due to the different application scenarios and clamped devices, when additional support is needed, such as a device to assist walking, a pressure bar 5 can be used. The patient's hand can be pressed on the pressure bar 5, and the pressure bar 5 plays an auxiliary support role for the patient.

[0041] At this time, when the pressure rod 5 is pressed, the spiral spring 32 is in a deformed state. If the patient falls, the external force applied at this time suddenly disappears, and the spiral spring 32 drives the rotating wheel 35 to rotate rapidly. Due to the high speed, under the action of centrifugal force, the claw 42 can be clamped outward into the card slot 44 at this time, and the cam 41 can be driven to rotate. The cam 41 touches the pressing switch 36, and an alarm can be issued.

[0042] For equipment such as treadmills, there is no need to press at this time. A pull rope can be used. By fixing the strap to the patient's arm, during normal exercise, the pull rope will drive the wheel 35 to rotate at a slower speed. If the patient falls, the pull rope will be pulled at a faster speed, and the pull rope will drive the wheel 35 to rotate quickly. Due to the high speed, under the action of centrifugal force, the claw 42 can be clamped outward into the slot 44, and the cam 41 can be driven to rotate. The cam 41 touches the press switch 36, and an alarm can be issued.

[0043] The support seat 31 is rotatably connected to an adjustment plate 34, and the support seat 31 is threadedly connected to a second screw 33 for locking the rotation of the adjustment plate 34. The second screw 33 abuts against the adjustment plate 34. By loosening the second screw 33, the support seat 31 can be rotated around the adjustment plate 34, so that the angle of the support seat 31 can be adjusted. By tightening the second screw 33, the relative rotation of the support seat 31 and the adjustment plate 34 can be locked.

[0044] The adjustment plate 34 is slidably connected to the guide rod 16, and the adjustment plate 34 is threadedly connected to a first screw 17 for locking the sliding of the guide rod 16. The first screw 17 abuts against the guide rod 16. By loosening the first screw 17, the guide rod 16 can slide relative to the adjustment plate 34, so that the height of the support seat 31 can be adjusted. By tightening the first screw 17, the relative sliding locking of the guide rod 16 and the adjustment plate 34 can be achieved.

[0045] The guide rod 16 is fixedly connected with a transverse plate 22, and the transverse plate 22 is slidably connected with a pressure plate 21 that moves in the vertical direction. The pressure plate 21 is provided with a vertical hole 26, and the transverse plate 22 is slidably arranged in the vertical hole 26. The vertical hole 26 serves as a limit and guide for the sliding of the transverse plate 22, and the pressure plate 21 can slide vertically relative to the transverse plate 22.

[0046] The horizontal plate 22 is slidably connected to a movable plate 12 that can slide away from or towards each other. The movable plate 12 moves in the horizontal direction. The pressure plate 21 is provided with an inclined hole 23 that is inclined. The movable plate 12 is connected to a sliding shaft 18 that is movably arranged in the inclined hole 23.

[0047] When the pressure plate 21 and the cross plate 22 move relative to each other, under the action of the inclined hole 23, the sliding shaft 18 will move freely in the inclined hole 23, thereby driving the two movable plates 12 to move inward or separate outward at the same time. When moving inward, clamping can be achieved, and when separating outward, the clamping can be released.

[0048] The movable plate 12 is fixedly connected to the sleeve 1, and the sleeve 1 is slidably connected to the clamping plate 11 which moves horizontally. The ends of the clamping plates 11 which are close to each other are connected to rubber pads. The rubber pads can play a buffering role on the one hand to prevent the clamping force from being too large and damaging the instrument, and on the other hand to increase friction for easy fixation.

[0049] The sleeve 1 is threadedly connected with a screw rod 14, and a first spring 13 is arranged between the screw rod 14 and the clamping plate 11. One end of the first spring is in contact with the screw rod 14, and the other end of the first spring is connected to the clamping plate 11. When the screw rod 14 is rotated, the compressed length of the first spring 13 can be adjusted, thereby realizing the adjustment of the clamping force.

[0050] By rotating the screw 14, the elastic force of the first spring 13 between the screw 14 and the clamp 11 can be adjusted. By adjusting the elastic force, the clamping force at this time can be adjusted to prevent the clamping force from being too large and causing damage to the device, or the clamping force from being too small and causing the clamping to fail. It can be freely adjusted according to actual needs, can be fixed on different rehabilitation devices, and can be fixed at any position on the rehabilitation device.

[0051] The pressure plate 21 is slidably connected with a pawl 25, and the pawl 25 is connected to the pressure plate 21 through a third spring 24. The guide rod 16 is connected with a ratchet that matches the pawl 25. One end of the third spring 24 is connected to the pressure plate 21, and the other end of the third spring 24 is connected to the pawl 25. Under the action of the third spring 24, the pawl 25 and the ratchet are in a matched state, so that the pressure plate 21 can only move in one direction.

[0052] The pressure plate 21 is connected to the adjustment plate 34 through the second spring 15. The second spring 15 is sleeved on the guide rod 16. One end of the second spring 15 is connected to the pressure plate 21, and the other end of the second spring 15 is connected to the adjustment plate 34. The second spring 15 can realize that when the pawl 25 is pulled to release the limit on the ratchet, the second spring 15 can push the pressure plate 21 to reset, so that the pressure plate 21 and the cross plate 22 move to the initial state, and automatically release the clamping.

[0053] When the pressing plate 21 contacts the instrument, the support seat 31 continues to be pressed down. At this time, the pressing plate 21 and the cross plate 22 slide relative to each other, which can drive the movable plate 12 to move inward to achieve automatic clamping. When unlocking, only the ratchet 25 needs to be pulled to achieve automatic resetting of the pressing plate 21 and loosen the clamping plate 11. The fixing effect is good and the operation is very convenient, which can achieve automatic clamping of the instrument.

[0054] A method for using a rehabilitation medical wireless calling device with convenient position adjustment, using the above-mentioned rehabilitation medical wireless calling device with convenient position adjustment, comprises the following steps:

[0055] By holding the support seat 31, pressing the support seat 31 downward, the pressing plate 21 contacts the instrument, and the support seat 31 is continuously pressed downward, at which time the pressing plate 21 no longer descends, and the pressing plate 21 and the cross plate 22 slide relative to each other, and under the action of the inclined hole 23, the movable plate 12 can be driven to move inward, and the movable plate 12 drives the clamping plate 11 to move, and the clamping plate 11 can clamp the instrument;

[0056] The patient presses the pressure rod 5, which plays an auxiliary supporting role for the patient, and at this time the spiral spring 32 is deformed;

[0057] If the patient falls, the patient no longer presses the pressure rod 5. Under the action of the volute spring, the pressure rod 5 is driven to rotate, and the pressure rod 5 drives the rotating wheel 35 to rotate. As the rotating wheel 35 rotates faster, the claw 42 is inserted into the slot 44, and the rotating wheel 35 drives the cam 41 to rotate. The cam 41 touches the pressing switch 36, and the pressing switch 36 controls the alarm to work, thereby realizing the alarm.

[0058] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
