The delay circuit includes a capacitor C1, resistors R3 and R4, and a transistor Q2 connected via circuit board wiring. One end of the first resistor R3 is connected to one end of the second resistor R4 and the positive electrode of the capacitor C1. The negative electrode of the capacitor C1 is connected to the emitter of the transistor Q2. The other end of the second resistor R4 is connected to the base of the transistor Q2. The cough monitoring circuit includes a voltage stabilizing module A5, a voice control module A6, resistors R5 and R6, transistors Q3 and Q4, a relay J and a counter A7 connected via circuit board wiring. The positive power input terminal 1 pin of the voltage stabilizing module A3 is connected to the positive power input terminal 1 pin of the counter A7 and the emitter of the first transistor Q4. The negative power input terminal 2 pin of the voltage stabilizing module A5 is connected to the negative power input terminal 2 pin of the counter A7, the emitter of the second transistor Q3 and the negative power input terminal of the relay J. The power input terminals 1 and 2 pins of the voice control module A6 are connected to the voltage stabilizing module A3. The power output terminals 3 and 4 of the block A5 are connected respectively, the signal output terminal 3 of the voice control module A7 is connected to one end of the first resistor R6, the other end of the first resistor R6 is connected to the base of the first transistor Q4, the collector of the first transistor Q4 is connected to the positive power input terminal of the relay J, the control contact terminal and the normally open contact terminal of the relay J are connected to the two contacts under the cumulative counting key L of the counter A7 respectively, the signal output terminal 3 of the counter A7 is connected to one end of the second resistor R5, and the other end of the second resistor R5 is connected to the base of the second transistor Q3.

[0016] Figure 1 , 2As shown in, the power input terminals 1 and 2 of the time-controlled switch A and the two poles of the AC 220V power supply are connected via wires respectively, the power output terminals 3 and 4 of the power module A and the power input terminals 1 and 2 of the short message sending module A8, the power input terminals 1 and 2 of the pressure sensor A2, the positive input terminal of the power input terminal relay J1 of the bed-falling monitoring circuit and the emitter of the transistor Q1, and the power input terminals 1 and 2 of the power input terminal counter A7 of the cough monitoring circuit are connected via wires respectively; the signal output terminal 3 of the pressure sensor A2 and the other end of the adjustable resistor RP1 at the signal input terminal of the bed-falling monitoring circuit are connected via wires, the normally closed contact terminal of the signal output terminal relay J1 and the emitter of the transistor Q1 of the bed-falling monitoring circuit and the other end of the signal input terminal resistor R3 of the delay circuit and the negative electrode of the capacitor C1 are connected via wires respectively, and the collector of the transistor Q2 at the signal output terminal of the delay circuit, the collector of the transistor Q3 at the signal output terminal of the cough monitoring circuit and the two signal input terminals 4 and 3 of the short message sending module A8 are connected via wires respectively.

[0017] Figure 1 , 2As shown in , the new type is mainly used for monitoring patients with severe lung diseases and coughs in hospital wards, who are at risk of falling out of bed. After the AC 220V power supply enters the power input terminal of the time switch A, the 3rd and 4th pins of the time switch A output power for a certain period of time every day (for example, from 7 pm to 8 am the next day, or output power throughout the day) to the power input terminal of the power module A1, and the 3rd and 4th pins of the power module A1 output a stable DC 24V power supply to the power input terminal of the falling out of bed monitoring circuit, pressure sensor A2, and cough monitoring circuit. After the cough monitoring circuit is powered on, the 3rd and 4th pins of the voltage regulator module A5 output a 5V DC power supply to power the sound control module A6. When the patient does not cough, the ambient sound in the ward is relatively small, the 3rd pin of the sound control module A6 does not output a low level, the relay J will not be powered on, and the counter A7 will not accumulate counts; when the patient coughs, due to the loud sound, the 3rd pin of the sound control module A6 synchronously outputs a low level, the low level enters the base of the transistor Q4 through the resistor R6 for voltage reduction and current limiting, the transistor Q4 turns on the collector and outputs a low level to the positive power input terminal of the relay J, the relay J is powered on and its control contact terminal and the normally open contact terminal are closed once, so the counter A7 will accumulate counts once; through the above, every time When a patient in the ward coughs once, counter A7 will count up once; when the accumulated count of counter A7 reaches the number preset by the medical staff (for example, the number of coughs is greater than 30 times), pin 3 of counter A7 will output a high level and enter the base of transistor Q3 through the resistor R5 to reduce the voltage and limit the current. The transistor Q3 is turned on and the collector outputs a low level to enter the first signal input terminal 3 of the SMS sending module A8. Therefore, the SMS sending module A8 sends the first SMS stored internally. After the mobile phone of the nurses at the hospital nurse station receives the SMS, they can timely understand the specific situation of the corresponding patient according to the content of the SMS (for example, the SMS content is "102 coughs", which means that the patient in ward 102 has a more serious cough). When the medical staff arrives at the site or presses the reset button of counter A7 with their fingers every day, the accumulated count of counter A7 is reset, and the next number of coughs of the patient begins to be counted again.

[0018] Figure 1 , 2As shown, after the bed-fall monitoring circuit and the pressure sensor A2 are powered on, the patient's own weight plus the weight of the bed when he / she does not fall out of bed acts on the pressure sensor A2, and the voltage signal output by the 3rd pin of the pressure sensor A2 is relatively high. The voltage signal is divided by the adjustable resistor RP1 and the resistor R1, and the resistor R2 steps down and limits the current to enter the base of the transistor Q1, which is higher than 0.7V. The transistor Q1 is turned on and the collector outputs a low level to enter the negative power input terminal of the relay J1. The relay J1 is powered on and its control power input terminal and the normally closed contact terminal are open. In this way, the 24V power supply will not charge the capacitor C1 through the resistor R3, and the corresponding SMS sending module A8 will not send the second SMS. After the patient falls out of bed (including getting out of bed to go to the bathroom, etc.), his own weight no longer acts on the pressure sensor A2. The voltage signal output by the 3rd pin of the pressure sensor A2 is relatively low. The voltage signal is divided by the adjustable resistor RP1 and the resistor R1. The resistor R2 reduces the voltage and limits the current to enter the base of the transistor Q1 below 0.7V. The collector of the transistor Q1 is cut off and no longer outputs a low level to enter the negative power input terminal of the relay J1. The relay J1 loses power and no longer attracts the control power input terminal and the normally closed contact terminal to close. In this way, the 24V power supply will charge the capacitor C1 through the resistor R3. In the initial period of time (for example, the time is less than 10 minutes, the time is equal to 1.1×resistance value of resistor R3×capacitance of capacitor C1, so the actual time can be adjusted in production), when the capacitor C1 is not fully charged, the 24V power supply passes through the resistors R3 and R4. The voltage reduction and current limiting entering the base of transistor Q2 is lower than 0.7V, transistor Q2 will not be turned on, then, the SMS sending module A8 will not send the second SMS; after the patient falls out of bed for a period of time (for example, the time is greater than 10 minutes), when the capacitor C1 is fully charged, the 24V power supply enters the base of transistor Q2 through the resistor R3 and the resistor R4, and the voltage reduction and current limiting entering the base of transistor Q2 is higher than 0.7V, and the transistor Q2 will be turned on and the collector outputs a low level to enter the second signal input terminal 4 of the SMS sending module A8, so the SMS sending module A8 sends the second SMS stored inside, and after the mobile phone of the nurse staff at the hospital nurse station receives the SMS, it can respond to the patient's specific situation in time according to the content of the SMS (for example, the SMS content is "203 falls out of bed", which means that the patient in ward 203 may have fallen out of bed accidentally, etc.). This new type delays through the delay circuit, and its main function is to prevent the patient from getting out of bed and going to the bathroom normally, etc., and the SMS sending module from sending SMS unnecessarily.

[0019] Figure 1 , 2As shown above, the present invention can monitor the coughing of patients with severe lung diseases in real time at night (or throughout the day) as needed, and can monitor in real time whether patients at risk of falling out of bed have fallen out of bed. When the patient coughs severely or falls out of bed due to his / her illness, the on-duty nurses at the nurse station can be reminded in time by SMS (including the bed number and the patient's specific situation), and the on-duty nurses can arrive at the scene in time for disposal, thereby bringing convenience to nurses, reducing the labor intensity of nurses, and ensuring the safety of patients as much as possible. Figure 2In the figure: the resistance values ​​of resistors R1, R2, R3, R4, R5 and R6 are 4.7K, 10K, 5.4M, 470K, 10K and 10K respectively; the transistors Q1, Q2 and Q3 are 9013 (NPN transistors); the transistor Q4 is 9012 (PNP transistor); the resistance value of the adjustable resistor RP1 is 47K (adjusted to 10.2K in this embodiment); the power module A1 is a finished product of a switching power module for converting AC 220V to DC 24V; the voltage stabilizing module A5 is a finished product of a DC-DC power module for converting DC 24V to DC 5V; the relays J and J1 are DC24V relays; the capacitor C1 is a 100μF model / 25V electrolytic capacitor, time control switch A is a microcomputer time control switch product of model ZYT16G-2A, which has two power input terminals, two power output terminals, and seven setting buttons. The 7 setting buttons can be operated separately to set the interval time of the power output of the two power output terminals; the sound control module A6 is a sound sensor module of model zave, which has two power input terminals and a signal output terminal. When a certain decibel of sound is detected during operation, the signal output terminal will output a low-level signal (with a sound threshold adjustment knob, when the external sound signal is adjusted to the left, the signal output terminal will output a low level, on the contrary, when the external sound signal is relatively high , the signal output terminal outputs a low level). It should be noted that although external sounds such as thunder or quarrels can cause the voice control module A6 to output signals, the above situation rarely occurs after all, and nurses can take corresponding measures according to the specific circumstances; Counter A7 is a finished counter of model jk-72s, which has two power input terminals, an alarm power output terminal, etc., and also has four setting buttons (including a reset button and an accumulated counting button). Each time the two contacts under the accumulated counting button are closed, the accumulated count is counted once, and each time the two contacts under the reset button are closed, the accumulated count is reset to zero. By operating the four setting buttons separately, the accumulated count can be set to the latter (For example, set it to 30 times), the alarm power output terminal outputs a high-level signal; the SMS sending module A8 is a 6-way switch 4G SMS alarm module of the brand Biyin Technology, which has two power input terminals 1 and 2, and six low-level signal input terminals 3-8. After each low-level signal input terminal inputs a low-level signal, it can send six text messages respectively (six text messages are pre-stored, and this new model has two text messages pre-stored); the pressure sensor A2 is a finished pressure sensor of model HZC-H1, which has two power input terminals and one power output terminal (outputting 0-5V voltage signal). The greater the detected weight, the higher the output voltage signal, and vice versa.
