DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides Figures 1 to 8 The shown example is an early warning bed call device capable of detecting heart rate, comprising a call control box 1, a display screen 2 and a wire 3. The display screen 2 can be mounted on a wall, the call control box 1 is connected to the display screen 2 via the wire 3, a call button 4 is provided on the call control box 1, and the bed call device is activated by pressing the call button 4.

[0028] Considering that the call control box 1 is connected and hung on the display screen 2 through the wire 3, when there is a caregiver accompanying the patient, the caregiver can assist in pressing the call button 4 to call the nurse or doctor on duty. However, when the caregiver is out, the patient usually needs to hold the call control box 1 to call after raising his head, turning over, stretching his hand, etc., which is cumbersome to operate. Especially for some patients with hand tremors, it is easy to make untimely calls. In order to improve the efficiency of the bed call device, a U-shaped frame 5 is clamped on the call control box 1, and a circular groove 6 is opened through the U-shaped frame 5. The circular groove 6 is distributed corresponding to the call button 4. The inside of the circular groove 6 is fixedly connected with a cylinder 7, and a sliding column 8 is slidably penetrated at one end of the cylinder 7 close to the call control box 1, and the sliding column 8 is T-shaped. The end of the sliding column 8 located inside the cylinder 7 has a large outer diameter to prevent it from sliding out directly from the end of the cylinder 7. The sliding column 8 can also rotate on the cylinder 7.

[0029] In order to improve the stability of the clamping fit between the U-shaped frame 5 and the call control box 1 , a clamping block 30 is fixedly connected to the U-shaped frame 5 , and a clamping slot 20 cooperating with the clamping block 30 is provided on the side wall of the call control box 1 , and the clamping block 30 is inserted into the inside of the clamping slot 20 .

[0030] A slide plate 11 is provided inside the cylinder 7 for sliding. A slide groove 12 is provided on the inner wall of the cylinder 7. A slider 13 is provided inside the slide groove 12 for sliding. The slider 13 is fixedly connected to the slide plate 11. The slide groove 12 and the slider 13 are provided so that the slide plate 11 can only slide inside the cylinder 7 but cannot rotate. A thread groove 9 is provided at one end of the slide column 8 away from the call button 4. The internal thread of the thread groove 9 is matched with a thread block 10. The thread block 10 is fixedly connected to the slide plate 11. Specifically, an external thread structure is provided on the thread block 10, and an internal thread structure (not shown in the figure) is provided on the thread groove 9. The external thread structure and the internal thread structure cooperate with each other, which is the same as the principle of the "ball screw" in the prior art; and in actual production, the surface of the external thread structure and the internal thread structure is relatively smooth, and can also be used with lubricating oil.

[0031] When the slide plate 11 drives the threaded block 10 to perform linear motion under the limiting action of the slide groove 12 and the slide block 13, the slide post 8 will perform rotational motion due to the threaded fit between the thread groove 9 and the threaded block 10.

[0032] The U-shaped frame 5 is fixedly connected with an air bag 23. An air hole 14 is provided at one end of the air cylinder 7 away from the call button 4. The air cylinder 7 is connected with the air bag 23 through the air hole 14. The air bag 23 is U-shaped, has a large contact area, and can be adjusted according to specific usage conditions. When the air bag 23 is pressed, the air bag 23 shrinks, and the gas inside the air bag 23 enters the interior of the air cylinder 7 through the air hole 14.

[0033] During the period of accompanying personnel, the U-shaped frame 5 is clamped on the back of the call control box 1 (refer to Figure 2 ), when the accompanying personnel finishes using the call control box 1 and puts down the call control box 1, the airbag 23 will first abut against the wall, playing a shock-absorbing and buffering effect to protect the call control box 1.

[0034] When the accompanying person goes out, the U-shaped frame 5 is clamped on the side of the call control box 1 close to the call button 4, and the circular groove 6 is distributed corresponding to the call button 4.

[0035] The first protrusion 21 is fixedly connected to the end of the slide post 8 close to the call button 4, and the second protrusion 22 is integrally formed on the call button 4. The second protrusion 22 is provided in plurality, and the plurality of second protrusions 22 are distributed in a circular array, and the first protrusion 21 cooperates with the second protrusion 22. The ends of the first protrusion 21 and the second protrusion 22 close to each other are both provided with rounded corners for easy extrusion and fit. When the slide post 8 drives the first protrusion 21 to rotate, when the first protrusion 21 is in extrusion contact with one of the second protrusions 22, the call button 4 is squeezed by the second protrusion 22, so as to achieve the effect of starting the bed call device; and a plurality of second protrusions 22 are provided, and when the slide post 8 rotates, the first protrusion 21 cooperates with the plurality of second protrusions 22 to press the call button 4 multiple times.

[0036] The first ring 17 and the second ring 18 are slidingly provided on the outside of the sliding column 8, the first ring 17 is fitted on the sliding column 8, and the second ring 18 is fitted on the inner wall of the cylinder 7. The outside of the sliding column 8 is sleeved with a spring 19, one end of the spring 19 is fixedly connected to the first ring 17, and the other end of the spring 19 is fixedly connected to the second ring 18. The first ring 17, the second ring 18 and the spring 19 are arranged to cooperate with each other without affecting the rotation of the sliding column 8.

[0037] A first magnet 15 is fixedly connected to the thread block 10, and a second magnet 16 is fixedly connected to the inner wall of the thread groove 9. The first magnet 15 and the second magnet 16 repel each other, and the magnetic properties of the first magnet 15 and the second magnet 16 on the sides close to each other are the same; and the elastic supporting force of the spring 19 is smaller than the repulsive force between the first magnet 15 and the second magnet 16.

[0038] Specifically, when there is a caregiver, when the caregiver finishes using the call control box 1 and puts down the call control box 1, since the airbag 23 is in a U shape, the airbag 23 will first abut against the wall, thereby achieving a shock-absorbing and buffering effect; when the airbag 23 abuts against the wall, it will adaptively shrink, and the gas inside it enters the interior of the air cylinder 7 through the air hole 14, squeezing the slide plate 11 to move toward the call control box 1. Since the elastic supporting force of the spring 19 is less than the repulsive force between the first magnet 15 and the second magnet 16, the slide plate 11, the threaded block 10, and the slide column 8 first slide toward the call control box 1 and squeeze the spring 19 to shrink, and the spring 19 performs force unloading and buffering; when the spring 19 is fully contracted, the threaded block 10 is recovered to the interior of the thread groove 9 and overcomes the repulsive force between the first magnet 15 and the second magnet 16, further improving the force unloading and buffering effect, thereby avoiding damage to the call control box 1 due to touching the wall, etc., and extending the service life.

[0039] There is a certain gap between the air cylinder 7 and the outer wall of the back of the call control box 1, so that the slide column 8 can slide toward the call control box 1, which is convenient for the spring 19 to contract and buffer.

[0040] Furthermore, when the accompanying person goes out and the patient needs to call, the patient presses the airbag 23, the airbag 23 shrinks, and the gas inside it enters the interior of the air cylinder 7 through the air hole 14, squeezing the slide plate 11 to move toward the call control box 1, and presents a linear motion state under the limiting action of the slide groove 12 and the slider 13. Since the elastic supporting force of the spring 19 is less than the repulsive force between the first magnet 15 and the second magnet 16, the slide plate 11, the threaded block 10, and the slide column 8 first slide toward the call control box 1 and squeeze the spring 19 to shrink, and the slide column 8 extends out from the interior of the air cylinder 7. At this time, the first protrusion 21 can be squeezed and matched with the second protrusion 22; when the spring 19 is fully contracted, the slide plate 11 continues to move toward the call control box 1 (linear motion). Since the thread groove 9 and the thread block 10 are threadedly matched, the slide column 8 performs a rotational motion, thereby driving the first protrusion 21 to rotate. At this time, the thread block 10 overcomes the repulsive force between the first magnet 15 and the second magnet 16, and is in a state of being recovered to the inside of the thread groove 9 (that is, the distance between the first magnet 15 and the second magnet 16 is gradually reduced); when the first protrusion 21 is pressed and contacted with one of the second protrusions 22, the call button 4 will be squeezed by the second protrusion 22 to achieve the effect of starting the bed call device, and multiple second protrusions 22 are provided. When the slide column 8 rotates, the first protrusion 21 cooperates with multiple second protrusions 22 to press the call button 4 multiple times, ensuring that the bed call device can be successfully started and effectively call the nurse or doctor on duty.

[0041] By setting up structures such as the U-shaped frame 5, the airbag 23, and the sliding column 8, when squeezing the airbag 23, the call button 4 can be pressed multiple times to ensure that the bed call device can be successfully activated and effectively call the nurse or doctor on duty. At the same time, it can play a shock-absorbing and buffering effect to protect the call control box 1. Compared with the call button 4, the airbag 23 has a larger contact area, which is convenient for patients to use and ensures the efficiency of the call.

[0042] By arranging the spring 19, the first magnet 15 and the second magnet 16 and other structures in conjunction with the airbag 23, the force unloading and buffering effect is improved, thereby preventing the call control box 1 from being damaged due to touching the wall, etc., and extending the service life.

[0043] After use, the restoring elastic force of the spring 19 and the repulsive force between the first magnet 15 and the second magnet 16 restore the structures such as the slide plate 11 to facilitate subsequent use.

[0044] Considering that when the patient directly controls the call control box 1, the wire 3 needs to have a sufficient length, and when the accompanying person presses, a longer wire 3 is not needed. In order to improve the flexibility of use, a sliding sleeve 26 is slidably provided on the wire 3, and a lace 27 is fixedly connected to the sliding sleeve 26. There is a certain friction between the sliding sleeve 26 and the wire 3, and it will not slide at will. The lace 27 is provided with a Velcro 29, including a magic thorn hair, a magic hook hair, etc. The Velcro 29 and its working principle are both existing common technologies, and will not be repeated here.

[0045] Specifically, when there is a caregiver, part of the wire 3 can be rolled up, the sliding sleeve 26 can be slid to a suitable position of the wire 3, and the rolled up part can be tied by the lace 27 and the Velcro 29 to reduce the occupied space and avoid interference with other operations.

[0046] Furthermore, when the accompanying person goes out, the Velcro 29 is loosened, the lace 27 is opened, and the wire 3 is stretched to a certain length to ensure that the call control box 1 can be placed near the patient's hand, and the control sleeve 26 slides on the wire 3 toward the call control box 1 (refer to Figure 1 ), and then tie the strap 27 to the patient's wrist through the cooperation of the Velcro 29 to prevent the call control box 1 from slipping and failing to call.

[0047] By providing the laces 27 and the Velcro 29, the wire 3 can be rolled up and tied to reduce the occupied space and avoid interference with other operations. At the same time, when the patient needs to directly control the call control box 1, the laces 27 can be tied at the wrist with the cooperation of the Velcro 29 to prevent the call control box 1 from slipping and being unable to call.

[0048] A heart rate monitor 28 is provided on the strap 27, and the heart rate monitor 28 cooperates with the strap 27, which is the same as the common heart rate monitoring bracelet in the prior art. When the strap 27 is tied to the wrist through the Velcro 29, the heart rate monitor 28 fits the pulse and detects the patient's heart rate.

[0049] Considering that when the pain is aggravated, it is necessary to call the nurse or doctor on duty, and the heart rate will also increase at this time. In order to achieve the effect of early warning, the side of the slide plate 11 facing away from the threaded block 10 is fixedly connected with a third magnet 25, and the inner wall of the air cylinder 7 is fixedly connected with an electromagnet 24, and the third magnet 25 cooperates with the electromagnet 24. A controller can be set to connect between the heart rate monitor 28 and the electromagnet 24. When the heart rate exceeds the set threshold, the electromagnet 24 will be activated by the controller. The controller and its working principle are both existing common technologies and will not be described in detail here.

[0050] At the same time, a power supply device is arranged on the U-shaped frame 5 to supply power to the electromagnet 24, and the power supply device includes a battery and other structures.

[0051] Specifically, when the pain intensifies, the heart rate speeds up. When the heart rate exceeds the set threshold, the electromagnet 24 is activated by the controller, and the magnetic properties of the third magnet 25 and the electromagnet 24 that are close to each other are of the same polarity. Under the action of the repulsive force, the slide plate 11, the threaded block 10, and the slide column 8 move a certain distance toward the call control box 1. Subsequently, only a slight press on the airbag 23 can make the first protrusion 21 contact the second protrusion 22, thereby achieving an early warning effect, thereby realizing a quick call when the pain intensifies.

[0052] In addition, a second threshold value can be set so that when the heart rate exceeds the threshold value, the magnetism of the electromagnet 24 is large enough to enable the slide plate 11 and other structures to drive the first protrusion 21 to directly contact the second protrusion 22, thereby activating the bed call device, which can be adjusted according to specific usage conditions.

[0053] By providing structures such as the electromagnet 24 and the heart rate monitor 28, the first protrusion 21 and the second protrusion 22 can be brought into contact with each other by lightly pressing the airbag 23, thereby achieving an early warning effect, thereby realizing a quick call when the pain intensifies.

[0054] Working principle: When there is a caregiver, the U-shaped frame 5 is connected to the back of the call control box 1 (refer to Figure 2 ), when the accompanying personnel finishes using the call control box 1 and puts down the call control box 1, since the airbag 23 is in a U shape, the airbag 23 will first abut against the wall, playing a shock-absorbing and buffering effect; when the airbag 23 abuts against the wall, it will adaptively shrink, and the gas inside it enters the interior of the air cylinder 7 through the air hole 14, squeezing the slide plate 11 to move toward the call control box 1. Since the elastic supporting force of the spring 19 is less than the repulsive force between the first magnet 15 and the second magnet 16, the slide plate 11, the threaded block 10, and the slide column 8 first slide toward the call control box 1 and squeeze the spring 19 to shrink, and the spring 19 performs force unloading and buffering; when the spring 19 is completely contracted, the threaded block 10 is recovered to the interior of the thread groove 9 and overcomes the repulsive force between the first magnet 15 and the second magnet 16, further improving the force unloading and buffering effect, thereby avoiding damage to the call control box 1 due to touching the wall, etc., and extending the service life.

[0055] When there is a caregiver, part of the wire 3 can be rolled up, the sliding sleeve 26 can be slid to a suitable position of the wire 3, and the rolled up part can be tied up by the lace 27 and the Velcro 29 to reduce the occupied space and avoid interference with other operations.

[0056] When the accompanying person goes out, the U-shaped frame 5 is clamped on the side of the call control box 1 close to the call button 4, and the circular groove 6 is distributed corresponding to the call button 4; the Velcro 29 is loosened, the lace 27 is opened, so that the wire 3 is stretched to a certain length to ensure that the call control box 1 can be placed near the patient's hand, and the control sleeve 26 slides on the wire 3 toward the call control box 1 (refer to Figure 1 ), and then tie the strap 27 to the wrist through the cooperation of the Velcro 29 to prevent the call control box 1 from slipping and failing to call; and the heart rate monitor 28 fits the pulse to detect the patient's heart rate.

[0057] When a call is needed, the patient presses the airbag 23, and the airbag 23 contracts. The gas inside the airbag 23 enters the interior of the air cylinder 7 through the air hole 14, squeezing the slide plate 11 to move toward the call control box 1, and presents a linear motion state under the limiting action of the slide groove 12 and the slider 13. Since the elastic supporting force of the spring 19 is less than the repulsive force between the first magnet 15 and the second magnet 16, the slide plate 11, the threaded block 10, and the slide column 8 first slide toward the call control box 1 and squeeze the spring 19 to contract, and the slide column 8 extends out from the interior of the air cylinder 7; when the spring 19 is fully contracted, the slide plate 11 continues to move toward the call control box 1 (linear motion). Since there is a thread between the thread groove 9 and the thread block 10, The first protrusion 21 is pressed and matched with the second protrusion 22, so that the slide column 8 performs a rotational motion, thereby driving the first protrusion 21 to rotate. At this time, the threaded block 10 overcomes the repulsive force between the first magnet 15 and the second magnet 16, and is in a state of being recovered to the inside of the thread groove 9 (that is, the distance between the first magnet 15 and the second magnet 16 is gradually reduced); when the first protrusion 21 is pressed and contacted with one of the second protrusions 22, the call button 4 will be squeezed by the second protrusion 22 to achieve the effect of starting the bed call device, and a plurality of second protrusions 22 are provided. When the slide column 8 rotates, the first protrusion 21 is pressed and matched with the plurality of second protrusions 22, and the call button 4 is pressed multiple times to ensure that the bed call device can be successfully started and the nurse or doctor on duty can be effectively called.

[0058] Moreover, compared with the call button 4, the airbag 23 has a larger contact area, which is convenient for the patient to use and ensures the efficiency of the call.

[0059] After use, the restoring elastic force of the spring 19 and the repulsive force between the first magnet 15 and the second magnet 16 restore the structures such as the slide plate 11 to facilitate subsequent use.

[0060] In addition, during use, the heart rate monitor 28 detects the patient's heart rate. When the pain worsens, the heart rate accelerates. When the heart rate exceeds the set threshold, the electromagnet 24 is activated through the controller, and the magnetic properties of the third magnet 25 and the electromagnet 24 that are close to each other are of the same nature. Under the action of the repulsive force, the slide plate 11, the threaded block 10, and the slide column 8 move a certain distance toward the call control box 1. Subsequently, only a slight press on the airbag 23 can make the first protrusion 21 and the second protrusion 22 squeeze and contact, thereby achieving an early warning effect, thereby realizing a quick call when the pain worsens.
