The circuit board is provided with a photosensitive module whose light brightness value is negatively correlated with the resistance value, the photosensitive module is electrically connected with a control module, the photosensitive module detects the light brightness value and sends it to the control module, and the control module controls the connection with the control module. A dimming module located in the power supply circuit of the indicator light, the dimming module is connected in series with the indication branch, and the control module controls the dimming module to reduce the light brightness of the indicator light when the light brightness value is less than the brightness threshold.

The beneficial effects of this program are:

1. When the patient needs to use the call button, the patient only needs to press the call button to send the call signal; in the process of using the call terminal, the light of the indicator light in the call button shines through the transparent plate, so that the patient can see the call button clearly. At the same time, the identifier on the transparent plate is opaque to light. After the light irradiates the transparent plate, it will form an identifier shape to instruct the patient, so that the patient can identify different buttons representing different functions, so that the patient can accurately press the button to make a call, so that the patient can use See the corresponding indicators clearly and promptly.

2. The photosensitive module on the call button detects the light brightness value in the environment and sends it to the control module. When the light brightness value is less than the brightness threshold, such as at night, the control module controls the dimming module to reduce the light brightness of the indicator light. The brightness of the light generated by the lamp itself will also illuminate the photosensitive module and the brightness of the light in the environment. The brightness value of the light detected by the photosensitive module during the day is relatively large, but when it is resting at night, the brightness of the light in the environment is greatly reduced. The brightness value of the light in the environment detected by the photosensitive module will be much smaller, and the brightness value of the light detected by the photosensitive module during the day and night is quite different, so the light brightness of the indicator itself and the light brightness of the environment will not affect the photosensitive module. As a result, the dimming module cannot adjust the light according to the light brightness value detected by the photosensitive module, and the light brightness of the indicator light on the call button is reduced at night, so as to avoid the call button being too bright and affecting the patient's rest.

A photosensitive module whose light brightness value is negatively correlated with the resistance value is welded on the circuit board. The photosensitive module can use the existing ALS-PDIC144-6C/L378 light sensor. The photosensitive module is electrically connected with a control module, and the control module can use the existing C8051F120 single-chip microcomputer. The photosensitive module detects the light brightness value and sends it to the control module. The control module controls and connects the dimming module located in the power supply circuit of the indicator light 5. The dimming module can use the second adjustable resistor 17 of the existing 3296W-103 model. The dimming module In series with the indicator circuit of the indicator light 5, the control module controls the dimming module to reduce the light brightness of the indicator light 5 when the light brightness value is less than the brightness threshold value, and the brightness threshold value is equal to the normal light brightness of the indicator light 5.

The circuit board is soldered with a temperature sensor module 3 that is connected to the control module by a signal. The temperature sensor module 3 can use the existing MLX90615 sensor. Each call button 2 is provided with a temperature sensor module 3, and a temperature sensor module 3. The ends of the sensor are protruding from the surface of the transparent plate 4 to prevent the sensor from being blocked by the transparent plate 4 and unable to send signals. The temperature sensing module 3 detects the temperature value at the patient's finger and sends it to the control module. When the temperature value is greater than the temperature threshold, the control module Control the light brightness of the indicator light 5 where the temperature sensing module 3 is located to increase, and the control module controls the resistance of the regulator in the branch to decrease when the temperature value is greater than the temperature threshold, so that the light brightness of the indicator light 5 in the branch is enhanced, After receiving the call signal of the call button 2, the control module controls the resistance of the regulator in the branch to increase, so that the light brightness of the indicator light 5 in the branch is weakened.

As shown in FIG. 2 , the bottom of the call button 2 is provided with a card slot 8 , a conductive sheet 9 is welded in the card slot 8 , and a plurality of T-shaped key bases 11 are welded on the circuit board. Abutting block 12 is welded on the key base 11, the key base 11 and the abutting block 12 are supported by insulating materials, the call button 2 is sleeved on the key base 11 through the card slot 8, and the key base 11 is welded with a conductive In the contact switch 10 connected with the sheet 9, an elastic reset member is sleeved between the call button 2 and the key base 11, and the elastic reset member includes an annular elastic air bag 13, and the elastic air bag 13 is sleeved between the call button 2 and the key base 11, The elastic airbag 13 is filled with a sponge 15 adsorbed with a disinfectant, and the disinfectant can be alcohol. The elastic airbag 13 is provided with an insertion hole 14 that can be inserted into the slot wall of the card slot 8, and the side wall of the call button 2 is bonded with an extension. To the water-absorbing layer 18 on the groove wall of the card slot 8, the water-absorbing layer 18 can be made of existing water-absorbing resin.

Four motors are installed in the housing 1, and the motors can be micro motors of the existing ZWMD006006 model. The adjustment pieces of the first adjustable resistor 16 and the second adjustable resistor 17 are clipped with rotating shafts, and each rotating shaft is welded to the output of the motor. On the shaft, the control module controls the dimming module or the regulator to control the motor to rotate when the resistance value is changed.

The specific implementation process is as follows:

Under normal light conditions during the day, when the patient needs to use the call button 2, the patient only needs to press the call button 2 to send a call signal; during the use of the call terminal, the light from the indicator light 5 in the call button 2 shines through the transparent plate 4. Allow the patient to see the call button 2 clearly, and the identifier on the transparent plate 4 is opaque to light. After the light irradiates the transparent plate 4, it will form an identifier shape to instruct the patient, so that the patient can distinguish different buttons representing different functions. Let the patient press the button accurately to make a call, and let the patient see the corresponding indicator clearly and timely when using it.

When the light is weak and dim at night, the photosensitive module on the call button 2 detects the light brightness value in the environment and sends it to the control module. When the light brightness value is less than the brightness threshold, that is, at night, the control module controls the motor as the dimming module. Rotation, the motor drives the adjustment piece of the second adjustable resistor 17 to rotate to increase the resistance value, reduce the current in the circuit, and reduce the light brightness of the indicator light 5, because the light brightness generated by the indicator light 5 itself will also be illuminated. The photosensitive module, and the brightness of the light in the environment, the light brightness value detected by the photosensitive module during the day is relatively large, while at night, the light brightness in the environment is greatly reduced, and the light brightness value in the environment detected by the photosensitive module will be higher. It is much smaller, and the light brightness value detected by the photosensitive module during the day and night is quite different, so the light brightness of the indicator light 5 itself and the light brightness of the environment will not affect the work of the photosensitive module. At night, lower the indicator light on the call button 2 5 light brightness, to avoid the call button 2 light is too bright and affect the rest of the patient.

Under the condition of weak and dim light at night, if the patient needs to use the call button 2 to call a nurse or doctor, the patient's finger touches the temperature sensing module 3 on the surface of the call button 2, and the temperature sensing module 3 sends the temperature value of the patient's finger to the control Module, because the temperature value of the patient's finger is higher than the temperature of the call button 2, the temperature of the call button 2 itself will not cause interference. When the temperature value of the control module is greater than the temperature threshold, the control module controls the first branch of the branch where the indicator light 5 is located. The motor corresponding to the adjustable resistance 16 drives the adjustment sheet to rotate to reduce the resistance value, increase the current of the indicator light 5 in the branch, so that the light brightness of the indicator light is enhanced, and the patient is instructed to use the call button 2. At the same time, only part of the The brightness of the indicator light 5 in the call button 2 is enhanced, so that the patient does not need to get out of bed to turn on the lights in the whole room for lighting, and it will not affect the rest of other patients in the same ward.

Before the call button 2 is pressed, the elastic airbag 13 pushes the call button 2 upward, so that the abutment block 12 on the slot wall of the card slot 8 abuts on the key base 11, when the patient presses the call button 2, the bottom of the call button 2 is locked in the slot 11. The groove wall of 8 is inserted into the insertion hole 14, the groove wall squeezes the sponge 15 in the elastic air bag 13, and squeezes out the disinfectant absorbed in the sponge 15, and the water-absorbing layer 18 on the groove wall absorbs the disinfectant, and the disinfectant is soaked. The water absorbing layer 18 sterilizes the call button 2 , and when the patient touches and presses the call button 2 , the water absorbing layer 18 can also sterilize the patient's fingers, thereby reducing the growth of bacteria in the gap of the call button 2 .

Since the energized part of the wet call button 2 is isolated by the key base 11 and the abutment block 12, and the water-absorbing layer 18 is not connected with the energized part, the call button 2 as a whole will not conduct electricity and cause safety problems.

Compared with the existing key switches with directly built-in fluorescent strips in this embodiment, the light in this embodiment is enhanced when needed, and the light intensity of the call button 2 can illuminate a small-scale environment at the same time, allowing the patient to directly find the corresponding call button 2 To send a call, there is no need to turn on the lights in the whole room, and when not in use, the light of the call button 2 is automatically weakened, which will not affect the rest of other patients. The existing key switches with built-in fluorescent strips are too weak, and it is difficult for patients to find the keys. The position of the switch, if the indication light intensity of the key switch is directly enhanced, it will easily affect the rest of the patient who is sensitive to light. On the basis of overcoming this problem, this embodiment also sterilizes the call button 2 often used by the patient to reduce calls. Bacteria grow in the crevice of button 2.

The above descriptions are only embodiments of the present invention, and common knowledge such as well-known specific structures and characteristics in the solution are not described too much here. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the structure of the present invention. These should also be regarded as the protection scope of the present invention, and these will not affect the implementation of the present invention. Effectiveness and utility of patents.
