The core of the technology of the present invention is: Provided is a medical instrument having a vibration alarm, the vibration alarm including a vibration circuit, a vibrator, and a controller. The vibrator can be mounted on the main circuit board of the medical device, so that the wiring is more convenient and easy to install; in addition, the vibrator can be mounted on the housing of the medical device, so that the vibration of the user is felt at the same power. Stronger and does not interfere with other electronic devices.

Hereinafter, a medical instrument with a vibration alarm provided by the present invention will be described in detail by taking an oximeter having a vibration alarm function as an example.

Referring to FIG. 1 , an oximeter with a vibration alarm function provided by the present invention includes: a central processing unit, a data collection unit, a data storage unit, a vibration alarm control unit, a display unit, and a power management unit (not shown).

The data collection unit is connected to the central processing unit for collecting the physiological parameter values of the subject, such as blood oxygenation values and pulse rate values, and transmitting them to the central processing unit.

The central processing unit receives the collected physiological parameter values such as blood oxygen value and pulse rate value, and determines whether the physiological parameter values such as the blood oxygen value and the pulse rate value collected by the collected value exceed their respective alarm thresholds, if Yes, an alarm command is issued to the vibration alarm control unit. The so-called alarm threshold is preset. For example, the following contents are preset: The upper limit of the blood oxygen level alarm threshold, the value range is 71~99; the lower limit of the blood oxygen value alarm threshold, the value range is 70~ 98; pulse rate value alarm threshold upper limit, its value range It is 31-235; and the lower limit of the pulse rate alarm threshold, which ranges from 30-234. In general, the central processing unit can employ, for example, a microcontroller (MCU), a microcontroller, or the like.

The vibration alarm control unit is connected to the central processing unit for receiving an alarm command from the central processing unit and issuing a corresponding vibration alarm signal according to the alarm command. In a practical application, the vibration alarm control unit may include a vibrator and a vibrator control circuit. Among them, the vibrator may be a vibration motor or the like. A vibrator control circuit is used to control the vibrator to initiate or stop vibration based on an alarm command from the central processing unit.

The data storage unit is coupled to the central processing unit for storing information such as blood oxygen, pulse rate, etc. under the control of the central processing unit. For example, information such as blood oxygen, pulse rate, and the like processed by the central processing unit may be stored, or information such as unprocessed blood oxygen, pulse rate, and the like collected by the data collection unit may be stored.

The display unit is connected to the central processing unit for displaying the measurement data, working mode and the like of the oximeter under the control of the central processing unit.

The power management unit is used to provide operating voltages for the various units and components in the oximeter.

In addition, the oximeter with vibration alarm function provided by the present invention further comprises a communication interface for communicating with an electronic device such as a PC, a monitor or a host computer under the control of the central processing unit. The communication interface can include a Bluetooth interface and/or a USB interface.

Referring to Figure 2, a specific implementation of the vibration alarm control unit of Figure 1 is shown. As shown, the vibration alarm control unit includes a vibration motor Bl, a diode D2, a transistor Q1, resistors R11, R12, R13, R14, capacitors C5 and C10.

Wherein, one end of the resistor R11 is connected to the resistor R12 and the capacitor CIO, and the other end of the resistor R11 is connected to a central processing unit such as an MCU to receive a control signal CTL-MOTOR from the MCU for the vibrator control circuit portion. Resistor R11, capacitor C10 and MCU form an electrical connection network to protect the vibrator control circuit section and the MCU control section. In practical applications, the resistance of resistor R11 can be 100Ω ± 5%; the capacitance of capacitor C10 can be 0.1 μ Ρ ± 20%; the resistance of R12 can be 1.5 Κ ± 5%.

The transistor Q1 is a 三-type transistor, for example, a three-pole type ΜΜΒΤ3094 can be used. Tube. When the PWM waveform given by the MCU is high, the collector C and the emitter E of the transistor Q1 are turned on, thereby forming a loop of Vbat-MOTOR-R14-Ql-GND, which causes the vibration motor B1 to start oscillating. Among them, the resistor R14 is a current limiting resistor. Based on the power consumption and vibration effect of the circuit, the resistance value is selected to be 51 Ω ± 5%. Of course, in practical applications, the vibration intensity can be controlled by adjusting the resistance of the resistor R14. The resistor R14 can be set as an adjustable resistor to facilitate control of the vibration intensity.

Capacitor C5 and diode D2 protect the vibration motor. It has been verified that the vibration motor B1 can be simply and effectively protected by setting the capacitor C5 and the diode D2 in this way, and the current electric protection function is prevented from being realized as follows: If the transistor Q1 is turned on, the vibration motor B1 starts to operate, and the instantaneous current is large. At this time, the capacitor C5 can provide some compensation to avoid excessive demand for the Vbat current; if the transistor Q1 is cut off, the vibration motor B1 stops working, and the electromotive force stored by the vibration motor B1 itself and the corresponding inertial energy need to be released in time (otherwise it may cause vibration) The life of the motor B1 is shortened, and even the vibration motor B1 is burned. At this time, the diode D2 provides the energy release circuit of the vibration motor B1, and the capacitor C5 can also provide partial power storage. In practical applications, the capacitance of capacitor C5 can be 0.1 μ F ± 20%. Diode D2 can be used with Schottky diodes of the type MBR0520.

Resistor R13 is the base bias voltage of transistor Q1 and can have a resistance of 4.99 Κ Ω ± 5%. The resistance of R12 can be 1.5ΚΩ士 5%.

The vibration motor B1 can use the model XY1027B002F vibration motor of Xinyu Electromechanical Co., Ltd.

In practical applications, the vibration mode can be set by setting the value representing the vibration mode by software. When the data collected by the 超 exceeds the limit, the MCU modulates the corresponding PWM wave according to the vibration mode to control the opening and closing of the transistor Q1 to control the vibration of the vibration motor B1, so the MCU can control the vibration motor B1 by the control signal CTL-MOTOR. Start or stop, vibration frequency, etc.

For example, if the blood oxygen value collected by the 釆 is greater than the upper limit of the blood oxygen value alarm threshold, the MCU sends an alarm command to the vibration alarm control unit, and the vibration alarm control unit responds to the instruction of the MCU, and according to The PWM wave modulated by the MCU controls the rhythm conduction and turn-off of the transistor Q1, thereby controlling the rhythmic vibration of the vibration motor B1. The PWM wave is modulated by the MCU according to the value set by the software. Therefore, the frequency of the vibration can be changed by software to obtain various vibration modes. Similarly, if the blood oxygen level collected by the 釆 is less than the lower limit of the blood oxygen value alarm threshold, or the pulse rate value collected by the 大于 is greater than the upper limit of the pulse rate value alarm threshold, or the pulse rate value collected by the 小于 is smaller than the pulse rate value alarm The lower limit of the threshold value, the oximeter with the vibration alarm function provided by the invention emits an alarm by vibration.

In fact, in practical applications, other switching circuits (e.g., Hall switching circuits) may be used instead of the aforementioned transistor Q1 to control the vibration of the vibration motor B1.

The alarm operation process of the oximeter with vibration alarm function provided by the present invention will be described in detail below with reference to FIG.

As shown in FIG. 3, in step 310, the blood oxygen level and the pulse rate value of the subject are collected.

Step 320: Determine whether the collected blood oxygen value is greater than a preset blood oxygen level alarm threshold upper limit, and if yes, go to step 340; if no, go to step 330.

Step 330: Determine whether the collected blood oxygen value is less than a preset hypoxic alarm threshold value, and if yes, go to step 340; if no, go to step 350.

In step 340, the vibration alarm is performed in the vibration mode 1. The so-called vibration mode 1 refers to a vibration mode that is used when the blood oxygen value exceeds its threshold. Of course, in practical applications, different vibration alarm modes can be set separately for exceeding the upper limit of the blood oxygen level alarm threshold and exceeding the lower limit of the blood oxygen level alarm threshold.

Step 350: Determine whether the pulse rate value of the collected subject is greater than a preset pulse rate threshold upper limit, if no, go to step 360; if yes, go to step 370.

Step 360: Determine whether the collected pulse rate value is less than a preset pulse rate value alarm threshold lower limit, if yes, go to step 370; if no, return to the main program.

In step 370, the vibration alarm is performed in the vibration mode 2. The vibration mode 2 refers to a vibration mode that is used when the pulse rate value exceeds its threshold value. Of course, in practical applications, different vibrations can also be set separately for exceeding the pulse rate value alarm threshold upper limit and exceeding the pulse rate value alarm threshold lower limit. Alarm mode. It can be understood that the vibration mode 2 can be different from the vibration mode 1 or the vibration mode 1, that is, the oximeter with the vibration alarm function can also set only one alarm mode, whether it is a blood oxygen value or a pulse rate value. This type of alarm mode is used as long as it exceeds its respective threshold.

It should be noted that, before step 310, the processing is further included: that is, the upper limit of the blood oxygen level alarm threshold, the lower limit of the blood oxygen level alarm threshold, the upper limit of the pulse rate value alarm threshold, and the pulse rate value alarm threshold are set by software. Lower limit, and set the vibration mode after the over limit. The default value of the oximeter with vibration alarm function provided by the invention is set as follows: the upper limit of the blood oxygen value alarm threshold is 99, the lower limit of the blood oxygen value alarm threshold is 90; the upper limit of the pulse rate value alarm threshold is 100, the pulse rate value The lower limit of the alarm threshold is 60. When the blood oxygen value collected by the sputum is greater than the upper limit value of the blood oxygen value alarm threshold or less than the lower limit value of the blood oxygen value alarm threshold value, the vibration mode 1 alarm is used, and the vibration alarm mode of the mode is "vibration-vibration- Vibration-vibration-vibration-vibration-vibration-vibration-vibration-vibration", and occurs every 10 seconds; when the pulse rate value collected by 釆 is greater than the pulse rate value alarm threshold upper limit value or less than the pulse rate value alarm When the lower limit value is exceeded, the vibration mode 2 alarm is used. The vibration alarm mode of this mode is: "vibration-vibration-vibration", which occurs every 15 seconds.

It should be noted that, in the actual application, when judging whether the collected blood oxygen value and the pulse rate value exceed the threshold value, the judgment order may not be limited to the order shown in steps 320 to 370 in FIG. 3, and It is also possible to use such an order: for example, first determine whether the pulse rate value exceeds its threshold value, and then determine whether the blood oxygen value exceeds its threshold; or, first, determine whether the pulse rate value and/or blood oxygen value exceeds its respective value. The lower limit of the threshold, and then determine whether the pulse rate value and / or blood oxygen value exceed their respective upper limit of the threshold, and so on.

In particular, according to the present invention, the user can also select any one of the vibration alarm, the audible alarm, the visual >3⁄4 alarm, and the two >3⁄4 alarm modes, and change other "alarm modes".

In particular, the vibration intensity of the vibrator according to the present invention can be set in advance so that the vibration intensity can be adjusted, i.e., the vibration power can be adjusted, thereby being suitable for people who have different vibration sensations, and can save unnecessary electric energy.

The unique vibration alarm function of the invention is different from the previous sound alarm and visual alarm, which brings more convenience to the user. For example, during nighttime sleep monitoring, the over-limit alarm can be realized without disturbing others.

According to the present invention, the setting parameters can be retained even after the power is turned off, and the setting is not required for the next power-on.

According to the present invention, the test data can be browsed locally through the foregoing display unit, and can also be uploaded and browsed, and the user can perform dynamic continuous monitoring on the blood oxygen physiological parameters, and upload the data to the PC or other upper computer for data analysis and data. There are two ways of uploading USB and Bluetooth. The vibration alarm can be set on the medical device itself or on the terminal of the medical staff engaged in nighttime sleep monitoring.

The parameters of the over-limit alarm can be blood oxygen, pulse rate, and ECG measurement data; the upper and lower limits of the alarm can be set.

In addition, in addition to the over-limit alarm, other alarm functions can be set, such as the finger-off alarm. If the vibration is turned on, the vibration alarm will occur when the finger is off. If the vibration is off, the sound will be alarmed when the finger is off.
