The first embodiment,

Referring to fig. 1, the present embodiment discloses a medical call control system, which mainly includes a medical device 11, a driving module 12 and a calling module 13, which are respectively described as follows.

The medical device 11 may be a monitor, a ventilator, an anesthesia machine, or the like, for detecting a physiological parameter of a patient and/or adjusting the amount of drug or oxygen administered to the patient, and generating a call signal when any one of the physiological parameter, the amount of drug administered, and the amount of oxygen administered is abnormal. It can be understood that the monitor is used for detecting physiological parameters (such as electrocardio, heart rate, blood oxygen, blood pressure, respiration, pulse and body temperature) of a patient, and when the change of a certain physiological parameter exceeds a correspondingly set reference range, the condition is considered to be abnormal; the respirator is used for adjusting the oxygen supply amount of the patient, and the abnormality is considered to occur when the oxygen supply amount exceeds a correspondingly set reference range; the function of the anesthesia machine is to adjust the dosage of the patient (such as the administration of anesthetic gas), and the dosage is considered to be abnormal when exceeding the corresponding set reference range.

The driving module 12 is connected to the medical device 11, and is configured to receive the call signal generated by the medical device 11 and convert the call signal into a driving signal. It can be understood that, because the call signal has a poor load-carrying capacity, it needs to be converted into a driving signal with a higher load-carrying capacity and a higher output power, so as to drive the operation of the call module 13 by using the driving signal.

The calling module 13 is connected with the driving module 12 and used for generating prompt information under the action of the driving signal. For example, the driving signal can drive the calling module 13 to generate a prompt message such as sound, light, text or symbols, which is used to remind the medical staff to know that some abnormal condition is generated in the current measurement of the medical device 11.

In the present embodiment, referring to fig. 2, the driving module 12 includes an enabling circuit 121, a relay 122, and an interface circuit 123.

The enable circuit 121 includes an input and an output (the input and the output are not labeled in fig. 2). Referring to fig. 1 and 2, an input terminal of the enable circuit 121 is connected to the medical device 11, and is capable of receiving a call signal output from the medical device 11 through its own input terminal, converting the call signal into an enable signal of a first voltage level (for example, an enable signal of a 5V level), and outputting the enable signal from an output terminal of the enable circuit 121.

The relay 122 includes a control terminal, a normally open terminal, and a first common terminal (the control terminal, the normally open terminal, and the first common terminal are not labeled in fig. 2); the relay 122 is configured to receive the enable signal output by the enable circuit 121 through its own control terminal, and short-circuit the normal terminal and the first common terminal under the effect of the enable signal, where short-circuit means that the normal terminal and the first common terminal are connected and electrically conducted.

The interface circuit 123 includes two wiring pins (the wiring pins are not labeled in fig. 2); two connection pins of the interface circuit 123 are connected to the normally-open end and the first common end of the relay 122, respectively, and are also used for connecting the call module 13; it will be appreciated that in the event that the normally open end of the relay 122 and the first common end are shorted, the two connection pins of the interface circuit 123 are also shorted, thereby rendering the line connected to the call module 13 conductive.

In one embodiment, referring to fig. 3, the enable circuit 121 includes a transistor Q1, a resistor R5, a resistor R6, a resistor R7, a resistor R14, a capacitor C19, a capacitor C20, and a diode D7. The triode Q1 includes a control terminal, a first terminal and a second terminal, wherein the control terminal is used for controlling the on/off of the first terminal and the second terminal, the control terminal can be considered as the base of the common triode, and the first terminal and the second terminal are the emitter and the collector of the common triode. In fig. 3, a control terminal of the transistor Q1 is connected to one terminal of the resistor R7, and the other terminal of the resistor R7 forms an input terminal of the enable circuit 121, which is used for receiving a call signal; the control end of the triode Q1 is grounded through a resistor R14, and a capacitor C19 is connected with the resistor R14 in parallel; a first end of the transistor Q1 is connected to one end of the resistor R5, and the other end of the resistor R5 forms an output end of the enable circuit 121, where the output end is used for outputting an enable signal; the other end of the resistor R5 is connected with the anode of the diode D7, the cathode of the diode D7 is connected with direct current (such as +5V) of a first voltage level through the resistor R6, and the diode D7 is connected with the resistor R6 in series and then connected with the capacitor C20 in parallel; the second terminal of transistor Q1 is coupled to ground (e.g., GND).

In a specific embodiment, referring to fig. 3, the control terminal, the normally open terminal and the first common terminal of the relay 122 are a5, a1 and a3, respectively, then the control terminal a5 can receive the enable signal output by the enable circuit 121, and the relay 122 short-circuits its normally open terminal a1 and the first common terminal a3 under the effect of the enable signal. It is understood that the normally-open terminal a1 and the first common terminal a3 are in an open state without the application of the enable signal.

In a specific embodiment, referring to fig. 3, the interface circuit 123 includes a diode D5, a diode D6, a capacitor C23, a capacitor C26, a magnetic bead L14, and a magnetic bead L11. In fig. 3, the two wiring pins of the interface circuit 123 are b1, b2, respectively, and the wiring pins b1, b2 form an external interface J5, and the external interface J5 is capable of outputting a driving signal. The cathode of the diode D5 is connected to a connection pin (e.g., connection pin b2) of the interface circuit 123, the cathode of the diode D5 is further connected to the first common terminal a3 of the relay 122 via the magnetic bead L14, the anode of the diode D5 is grounded, and the capacitor C23 is connected in parallel to the diode D5; the cathode of the diode D6 is connected to another connection pin (e.g., connection pin b1) of the interface circuit 123, and the cathode of the diode D6 is also connected to the normally open end a1 of the relay 122 via the magnetic bead L11; the anode of the diode D6 is grounded (e.g., GND), and the capacitor C26 is connected in parallel with the diode D6.

In a specific embodiment, referring to fig. 3, the relay 122 further includes a power supply terminal (see a2 for power supply terminal), a second common terminal (see a4 for second common terminal), a normally closed terminal (see a6 for normally closed terminal), and the interface circuit 123 further includes a magnetic bead L10. In fig. 3, the power supply terminal a2 of the relay 122 is used for connecting direct current of a first voltage level (e.g., +5V), and the second common terminal a4 of the relay 122 is connected to the cathode of the diode D5 via the magnetic bead L10.

It should be noted that the relay 122 may be a HFD23/005-1ZS relay, which has an inductance coil and an armature inside, and is powered by +5V, and when an enable signal is applied to the inductance coil, the inductance coil drives the armature to attract by magnetic force, so that the normally open end and the first common end are shorted together.

Note that, in the enable circuit 121, the diode D7 and the resistor R6 function to cancel the back electromotive force; for example, when the transistor Q1 is suddenly turned off from on, the inductor of the relay 122 generates a back electromotive force and releases the back electromotive force through the control terminal a5, and the back electromotive force enters the enabling circuit 121 and is dissipated through the diode D7 and the resistor R6; the resistor R6 is used as an absorption resistor of the electromotive force, so that the electromotive force can be consumed, the transistor Q1 is prevented from being damaged by the electromotive force, and the effect of protecting components is achieved.

In the interface circuit 123, the diodes D5 and D6 play a role of electrostatic protection, for example, to prevent the relay 122 from being damaged by static electricity generated by the call module connected to the external interface J5, and play a role of protecting components. In addition, the magnetic beads L10, L11, and L14 all function to filter out high frequency interference, thereby avoiding interference to the normal operation of the relay 122.

In one particular embodiment, referring to fig. 4, the call module 13 includes power supply lines 131 and an alarm 132. Since the external interface J5 formed by the two connection pins b1 and b2 of the interface circuit 123 in fig. 3 can be externally connected, the two connection pins b1 and b2 of the external interface J5 can be connected in series to the power supply line 131 of the call module 13, and when the two connection pins b1 and b2 are short-circuited, the power supply line 131 is turned on, for example, the power supply line 131 is turned on by the dc power VCC. In fig. 4, a reminder 132 is connected to the power supply line 131 for being supplied with power when the power supply line 131 is on, thereby operating to generate a reminder message in a preset form.

The indicator 132 may be a lamp, a horn, a screen, an electronic sign, or the like, and may generate an indication message such as a light, a sound, a character, or a symbol when the indicator is energized. It can be understood that the prompt message can be used for reflecting the abnormal condition to medical care personnel, and the medical care personnel can be facilitated to carry out emergency treatment on the patient.

Referring to fig. 1 to 4, when the medical device 11 does not generate a call signal, the transistor Q1 of the enabling circuit 121 is in a non-conducting state, the voltage of the control terminal a5 of the relay 121 is equal to +5V, and at this time, the voltages of the two ends of the inductor coil inside the relay 121 are both +5V and are in a non-operating state, so the normally open terminal a1 and the first common terminal a3 of the relay 121 are not shorted, and the connection pins b1 and b2 of the external connection J5 are also not shorted, so that a driving signal cannot be generated.

Referring to fig. 1 to 4, when any one of the detected physiological parameter, the dosage and the oxygen supply amount is abnormal, the medical device 11 generates a call signal, the call signal is at a high level and enters the enabling circuit 121, after the control terminal of the transistor Q1 in the enabling circuit 121 receives the call signal at the high level, the first terminal and the second terminal of the relay 122 are turned on, the control terminal a5 of the relay 122 is grounded (i.e. connected to GND) due to the conduction of the transistor Q1, and the two terminals of the inductor inside the relay 122 are energized to operate due to different voltages, by pulling the armature to short the normally open end a1 of the relay 122 to the first common end a3, the connection pins b1 and b2 of the external interface J5 also generate a driving signal due to short circuit, the driving signal has strong loading capacity and reaches the prompter 132 through the power supply line 131, and the prompter 132 works under the action of the driving signal and generates a preset form of prompting information.

It should be noted that, with the system structures shown in fig. 1 to fig. 4, as long as the medical device 11 has an abnormal measurement signal, the driving module 12 will immediately drive the calling module 13 to generate a prompt message, so that the medical staff can reach the patient site in time under the prompt of the prompt message, and perform emergency treatment or disease condition check on the patient under the monitoring of the medical device 11.

It is understood that some physiological signals can be measured by the medical device 2 through one sensor 21, and some physiological signals can be measured by a plurality of sensors 21 at the same time.

The processor 22 is connected to the sensor 21, and is configured to obtain a physiological parameter of the patient according to the physiological signal, compare the physiological parameter with a preset first parameter range, and generate a call signal when the physiological parameter is judged to exceed the first parameter range. For example, for the electrocardiographic signals, the physiological parameter processed by the processor 22 may be a heart rate value corresponding to the electrocardiographic signals, the heart rate value only needs to be compared with a standard range of 60-100 times/minute of normal people, and when the heart rate value exceeds the standard range, the processor 22 sends out a call signal through its own pin.

The driving module 23 is connected to the processor 22, and is configured to receive the call signal and convert the call signal into a driving signal; the driving signal is used for driving the external real-time power to generate the prompt message, for example, driving a calling module to perform power-on operation to generate the prompt message.
