Description

The present invention is a monitoring device for monitoring the biological information of the patient, as well as medical telemetry including the same, about the bedside monitor and medical equipment.

  The patient's biological information can be confirmed by a device such as a bedside monitor or a telemeter. For example, the patient's electrocardiogram can be confirmed by being acquired through an electrocardiogram cable connected to the patient and then displayed on a bedside monitor or displayed on a central monitor via a bedside monitor or telemeter. (See Patent Document 1). According to these devices such as a bedside monitor and a telemeter, various biological information including an electrocardiogram can be handled simultaneously.

Among the biometric information, the pulse is one of the biometric information that is confirmed most frequently, and there is a case where it is only necessary to check the pulse of the patient. Therefore, various methods for confirming the pulse have been proposed. For example, a light emitting diode (LED) mounted on a device such as a bedside monitor or a telemeter blinks in synchronization with the R wave of the electrocardiogram, or a synchronization mark such as a heart shape displayed on the liquid crystal panel blinks. And a built-in speaker that emits a synchronization sound. According to these methods, the pulse of the patient can be confirmed by the generated voice and display.
Japanese Patent Laid-Open No. 9-19409

  However, in the conventional method described above, inconvenience may occur when checking the pulse of the patient. For example, aside from an unconscious patient in an intensive care unit, it is difficult to check a pulse without waking up a sleeping patient in a ward or the like. First, touching a sleeping patient can wake the patient. Next, it is conceivable that the pulse is confirmed by means for confirming the biological information without touching the patient, such as a speaker or a display, but these devices are turned off while the patient is sleeping. In many cases, the patient's sleep may be disturbed by sound and display generated by turning them on.

  In addition, patients who can move on their own often use a telemeter to obtain biological information. In this case, a person who confirms the pulse, such as a doctor or a nurse, cannot confirm the patient's pulse unless he / she returns to the central monitor installed in the nurse station or the like.

  In addition, when a pulse is confirmed by voice or display, the patient may become nervous with respect to the voice or display, and the pulse may be accelerated or sleep may be disturbed. Furthermore, when confirming a pulse by voice, it becomes necessary to adjust the volume depending on the volume of the surrounding sound, and the operation becomes complicated. When confirming a pulse by display, it is difficult to see the display clearly. Sexual problems may also arise.

  Furthermore, the difficulty of confirming the pulse extends to a fundamental problem such as when the pulse of the patient is originally weak or when the skill level of the medical staff is low.

The present invention has been made in view of the foregoing, the monitoring can be confirmed the pulse of the patient by a simple operation device, and a medical telemetry including the same, to provide a bedside monitor and medical equipment With the goal.

  The power switch 101 switches on / off of power supply to the medical telemeter 100. When the power switch 101 is pressed, the supply of power from the battery accommodated in the battery box 102 is started or terminated.

  The battery box 102 accommodates a battery that supplies power to each device unit of the medical telemeter 100, for example, a rechargeable battery. The rechargeable battery accommodated in the battery box 102 can be charged by fitting the medical telemeter 100 to a charger holder (not shown), for example, a non-contact charging cradle.

  The event switch 103 is a switch for performing an authentication operation between the medical telemeter 100 and the biological information monitor. When the event switch 103 is pressed, a signal for operating a function preset in the biological information monitor is transmitted from the medical telemeter 100 to the biological information monitor. This setting function includes a function of displaying the patient's biological information transmitted from the medical telemeter 100 and a function of sounding a warning sound when an abnormality is detected from the displayed biological information.

  The lead lamp 105 is lit to warn the operator of the medical telemeter 100 that biological information such as electrocardiogram information is not properly acquired. More specifically, when the lead lamp 105 detects that the electrocardiogram electrode is not normally connected to the patient or the electrocardiogram cable connector 220 is not normally connected to the electrocardiogram electrode connector 110, the lead lamp 105 performs a predetermined time ( Turns on (for example, for 2 minutes).

  The charge lamp 106 indicates a charging state of the rechargeable battery housed in the battery box 102. The charge lamp 106 is turned on when, for example, the medical telemeter 100 is fitted in the non-contact charging cradle and charging starts, and blinks when charging is completed.

  The hanging belt attachment hole 107 is an attachment hole for attaching a strap for hanging the medical telemeter 100 from the neck.

  The electrocardiogram electrode connector 110 is a connector for inserting the electrocardiogram cable connector 220 of the electrocardiogram electrode cable 200. By inserting the ECG cable connector 220 into the ECG electrode connector 110, the medical telemeter 100 and the ECG electrode cable 200 are connected.

  The heartbeat output unit 120 is attached to the side surface of the medical telemeter 100. As shown in FIG. 2, the heartbeat output unit 120 is preferably attached at a position where the operator can hold down the medical telemeter 100 while holding it with one hand.

  The heartbeat output unit 120 is made of an elastic body such as rubber, and a space within which the pressed heartbeat output unit 120 can be displaced is provided therein. As shown in FIG. 2, when the heartbeat output unit 120 is pressed by an operator, the heartbeat output unit 120 notifies the operator of the pulse of the patient through tactile stimulation by vibration.

  More specifically, as shown in FIG. 3, the heartbeat output unit 120 notifies the operator of the patient's pulse by transmitting the vibration of the actuator 150 provided at the position where the heartbeat output unit 120 comes into contact when pressed. To do. The actuator 150 is configured to vibrate in synchronization with the R wave of the electrocardiogram signal detected from the patient. The heartbeat output unit 120, the actuator 150, and the peripheral configuration thereof will be described in more detail later with reference to FIG.

  An electrocardiogram electrode cable 200 as a sensor includes an electrocardiogram cable 210 and an electrocardiogram cable connector 220.

  The electrocardiogram cable 210 is connected to the patient's body and detects a biological signal indicating the biological information of the patient. Further, the shield wire of the electrocardiogram cable 210 has a function as an antenna for wirelessly transmitting the biological information and other information subjected to wireless signal processing by the medical telemeter 100 to the biological information monitor by radiating in the air.

  The electrocardiogram cable connector 220 is connected to the electrocardiogram electrode connector 110, and outputs a patient's biological signal detected by the electrocardiogram cable 210 to the medical telemeter 100.

  FIG. 4 is a diagram illustrating an example of an internal circuit of the medical telemeter 100 of FIG.

  In FIG. 4, the medical telemeter 100 includes an electrocardiogram amplifier 131, a respiration detection amplifier 132, a multiplexer 133, an analog-digital converter (hereinafter referred to as “A / D”) as a receiving system that receives a biological signal from the electrocardiogram electrode cable 200. 134). That is, the electrocardiogram amplifier 131, the respiration detection amplifier 132, the multiplexer 133, and the A / D converter 134 serve as a biometric information acquisition unit that acquires biometric information of a patient from the electrocardiogram electrode cable 200.

  The electrocardiogram amplifier 131 generates an electrocardiogram signal by amplifying a biological signal detected from the patient and input via the electrocardiogram electrode cable 200, and outputs the electrocardiogram signal to the multiplexer 133.

  The respiration detection amplifier 132 generates an impedance respiration signal by amplifying a change in impedance of the living body measured through the electrocardiogram electrode cable 200. The respiration detection amplifier 132 outputs the generated respiration signal to the multiplexer 133.

  The multiplexer 133 selectively outputs either the electrocardiogram signal input from the electrocardiogram amplifier 131 or the respiration signal input from the respiration detection amplifier 132 to the A / D converter 134. Here, the multiplexer 133 outputs the electrocardiogram signal and the respiratory signal to the A / D converter 134 in time series, that is, at predetermined time intervals. The control IC 180 controls which of the electrocardiogram signal and the respiratory signal the multiplexer 133 outputs.

  The A / D converter 134 performs analog-to-digital conversion on the electrocardiogram signal or respiration signal input from the multiplexer 133, and outputs the electrocardiogram signal or respiration signal, which is digital data after conversion, to the control IC 180.

  The medical telemeter 100 includes a high-frequency oscillation modulation circuit 141 and an RF (Radio Frequency) amplifier 142 as a transmission system for wirelessly transmitting biological information and other information to a biological information monitor such as a central monitor or a bedside monitor. .

  The high-frequency oscillation modulation circuit 141 digitally modulates information to be transmitted to the biological information monitor input from the control IC 180 at a predetermined carrier frequency, and generates a modulation signal. The high frequency oscillation modulation circuit 141 outputs this modulation signal to the RF amplifier 142.

  The RF amplifier 142 amplifies the modulation signal input from the high frequency oscillation modulation circuit 141. The RF amplifier 142 radiates this radio signal into the air via the ECG electrode connector 110 and the ECG cable connector 220 using the shield wire of the ECG cable 210 as an antenna.

  The medical telemeter 100 includes an actuator 150 as stimulation means for stimulating the sense of touch of a living body. The medical telemeter 100 includes a micro switch 160 and a driver 170 as driving means for driving the actuator 150 and notifying a person who touched the actuator 150 of the patient's pulse.

  The actuator 150 vibrates in synchronization with the R wave of the electrocardiogram signal acquired from the patient. That is, the actuator 150 moves up and down at the same timing as the patient's pulse. More specifically, the actuator 150 is intermittently driven by the driver 170 that has received a drive signal from the control IC 180 synchronized with the R wave of the patient's electrocardiogram signal.

  The actuator 150 can vibrate with a short vibration period that converges in a very short time, for example, 100 ms or less. Hereinafter, the vibration with such a short vibration cycle is referred to as “short vibration” as appropriate. The actuator 150 notifies the operator of a series of flow from the start to the stop of short vibration as a vibration feeling of one pulse by stimulating the living body of the operator, for example, a fingertip. Here, the vibration cycle of the actuator 150 is sufficiently shorter than the length of one pulse.

  The actuator 150 is composed of a combination of permanent magnets and electromagnets, and is of an electromagnetic induction type that can operate with a single power source and a low voltage. In addition to this, various types of actuators such as a plunger actuator, a shape memory alloy actuator, a laminated piezoelectric element actuator, or a mechanical actuator using a motor and a cam can be used as the actuator 150. An example of the plunger type actuator will be described later with reference to FIG.

  The micro switch 160 switches on and off the vibration of the actuator 150. The micro switch 160 is normally in an off state, and when the actuator 150 is pressed through the heartbeat output unit 120 and is displaced in the pressed direction, the micro switch 160 is further pressed by the actuator 150 and is turned on. That is, the micro switch 160 is turned on only while the operator presses the heartbeat output unit 120 to confirm the patient's pulse, that is, while the operator is actively touching the heartbeat output unit 120. The micro switch 160 continues to output a signal (hereinafter referred to as “vibration instruction signal”) to vibrate the actuator 150 to the control IC 180 while the micro switch 160 is on.

  Here, the heartbeat output unit 120, the actuator 150, the microswitch 160, and their peripheral mechanisms will be described with reference to FIG.

  The actuator 150 is accommodated in the support member 151. Since one end of the support member 151 is always urged in the surface direction (x direction in the drawing) by the coil spring 152, the actuator 150 can be displaced from the support center position by the expansion and contraction of the coil spring 152. . Further, since the other end of the support member 151 is connected to the wall surface by the rotation center portion 153, the actuator 150 can rotate around the connection portion.

  According to this configuration, when the heartbeat output unit 120 is pressed by the operator, the support member 151 compresses the coil spring 152 and is displaced in a direction opposite to the biasing direction (x direction in the drawing) of the coil spring 152. To do. Then, the micro switch 160 is pressed by a part of the displaced support member 151, and the micro switch 160 is turned on. During this ON state, the micro switch 160 continues to output a vibration instruction signal to the control IC 180.

  On the other hand, as shown in FIG. 5, when the heartbeat output unit 120 is not pressed by the operator, the support member 151 and the microswitch 160 are not in contact with each other, and therefore the microswitch 160 is in the off state.

  The driver 170 drives the actuator 150 in accordance with a drive signal input from the control IC 180 and synchronized with the R wave of the patient's electrocardiogram signal. That is, the driver 170 vibrates the actuator 150 at a timing synchronized with the patient's pulse.

  The medical telemeter 100 includes a control IC (Integrated Circuit) 180 for comprehensively controlling each device unit. The control IC 180 is realized by a gate array, for example.

  When the medical telemeter 100 is turned on, the control IC 180 performs initialization processing of each device unit. In addition, the control IC 180 performs control to switch which one of the electrocardiogram signal and the respiratory signal is output from the multiplexer 133. Further, the control IC 180 outputs biological information and other information for wireless transmission to a biological information monitor such as a central monitor and a bedside monitor to the high-frequency oscillation modulation circuit 141.

  The control IC 180 functions to confirm whether or not the medical telemeter 100 and the electrocardiogram electrode cable 200 are properly connected. More specifically, first, the control IC 180 switches the output of the multiplexer 133 to the electrocardiographic amplifier 131 side and takes in an electrocardiogram signal from the A / D converter 134. Next, the control IC 180 detects whether or not the electrocardiogram cable connector 220 is connected to the electrocardiogram electrode connector 110 by detecting the level of the electrocardiogram signal. The control IC 180 turns on the lead lamp 105 when they are not connected.

  The control IC 180 generates a drive signal for driving the actuator 150 while the vibration instruction signal from the micro switch 160 is input. More specifically, the control IC 180 analyzes the electrocardiogram signal input from the A / D converter 134 to detect the position of the R wave, and generates a drive signal synchronized with the detected position of the R wave. The control IC 180 outputs the generated drive signal to the driver 170.

  Finally, the medical telemeter 100 includes a power supply circuit 191 that boosts and supplies a voltage of a battery accommodated in the battery box 102 to a necessary voltage in each device unit, and a non-contact with respect to a rechargeable battery accommodated in the battery box 102. And a charging control circuit 192 having a power feeding coil inside.

  Hereinafter, the operation of the medical telemeter 100 configured as described above will be described. Here, when the medical telemeter 100 stays in the night mode, that is, the mode in which the patient's biological information is monitored but the video or audio output is not performed, the operator presses the heartbeat output unit 120. The case where a patient's pulse is confirmed by doing is demonstrated.

  As shown in FIG. 3, when the operator presses the heartbeat output unit 120, the actuator 150 is displaced in the direction opposite to the x direction in the figure. As a result, the micro switch 160 is pressed and the micro switch 160 is turned on. The micro switch 160 continues to output a vibration instruction signal to the control IC 180 during the ON state.

  The control IC 180 generates a drive signal for driving the actuator 150 while the vibration instruction signal is input, and outputs the generated drive signal to the driver 170. As described above, this drive signal is synchronized with the R wave of the electrocardiogram signal acquired from the patient.

  Then, the driver 170 intermittently drives the actuator 150 according to the drive signal input from the control IC 180. Thereby, the actuator 150 vibrates at a timing synchronized with the pulse of the patient. Here, since the force for pressing the coil spring 152 to turn on the micro switch 160 is sufficiently larger than the driving force of the actuator 150, the micro switch 160 does not turn off as the actuator 150 is driven.

  Further, as described above, since the actuator 150 vibrates with an extremely short vibration cycle, the operator confirms a series of flow from the start to the stop of the short vibration with high sensitivity as a vibration feeling of one pulse. be able to.

  The operator can check the patient's pulse by tactile sense through the short vibration of the actuator 150 while the heartbeat output unit 120 is pressed. That is, the operator senses a series of flow from the start to the stop of the short vibration of the actuator 150 as one pulse with the fingertip pressing the heartbeat output unit 120, and confirms the patient's pulse by counting this. can do. Since the pulse is confirmed by tactile sense, the patient's pulse can be confirmed without touching the patient and without any special operation regardless of the state of awakening or sleep. In particular, as in this example, even when the medical telemeter 100 is in the night mode and the patient is sleeping, the pulse can be confirmed as it is without awakening the patient.

  Next, an example in which a plunger actuator is used instead of the electromagnetic induction actuator 150 will be described with reference to FIG.

  FIG. 6 is a diagram showing the heartbeat output unit 120, the plunger actuator 230, the microswitch 160, and the mechanisms around them.

  In FIG. 6, the support member 151 accommodates the plunger-type actuator 230, can be rotated around the connection portion with the rotation center portion 153, and is biased in the surface direction (x direction in the drawing) by the coil spring 152. Has been.

  According to this configuration, when the operator depresses the heartbeat output unit 120, the support member 151 compresses the coil spring 152, and the micro switch 160 is turned on. During this ON state, the micro switch 160 outputs a vibration instruction signal to the control IC 180, and the control IC 180 outputs a drive signal to the driver 170. The driver 170 vibrates the plunger actuator 230 according to this drive signal.

  As shown in FIG. 6, the plunger actuator 230 requires a depth because of its structure, and therefore the structure is slightly larger than the electromagnetic induction actuator 150 shown in FIG. 3 or 5.

  Thus, in the present embodiment, the actuator 150 vibrates in synchronization with the R wave of the electrocardiogram signal acquired from the electrocardiogram electrode cable 200 connected to the patient. Thus, the operator can confirm the patient's pulse from tactile stimulation through the vibration of the actuator 150 obtained via the heartbeat output unit 120 by pressing the heartbeat output unit 120.

  In the present embodiment, the actuator 150 is driven only while the micro switch 160 is in the on state, and the micro switch 160 is in the on state only while the actuator 150 is pressed by the operator. As a result, the actuator 150 vibrates only while the operator is trying to confirm the pulse of the patient, and therefore the drive power of the actuator 150 can be suppressed to the minimum necessary.

(Embodiment 2)

  The heartbeat output unit 310 is attached to any position on the casing of the bedside monitor 300. In this example, the heartbeat output unit 310 is attached to the upper right corner of the front surface of the bedside monitor 300. This position is the position where the right thumb used for checking the patient's pulse is most easily touched.

  The heartbeat output unit 310 is made of an elastic body such as rubber, and a space is provided in the inside thereof so that the pressed heartbeat output unit 310 can be displaced. When the heartbeat output unit 310 is pressed by the operator, the heartbeat output unit 310 notifies the operator of the pulse of the patient through tactile stimulation by vibration.

  More specifically, the heartbeat output unit 310 notifies the patient's pulse by transmitting vibrations of an actuator provided in a position where the heartbeat output unit 310 is brought into contact with the operator to the operator. As described above, this actuator is configured to vibrate in synchronization with the R wave of the electrocardiogram signal acquired from the patient.

  The pilot lamp 320 is provided on any of the casings of the bedside monitor 300. In this example, the pilot lamp 320 is provided below the heartbeat output unit 310. The pilot lamp 320 is lit to illuminate the attachment position of the heartbeat output unit 310 on the casing of the bedside monitor 300. Thereby, even when the bedside monitor 300 stays in the night mode and the screen 330 is turned off, the operator does not lose sight of the heartbeat output unit 310 and confirms the patient's pulse even when the surroundings are dark. can do.

  The screen 330 displays biometric information and other information acquired from the patient.

  In the present embodiment, the electrocardiogram signal obtained from the patient may be detected from an electrocardiogram electrode cable connected to the bedside monitor 300, or may be detected by another monitoring device and transmitted via wire or wirelessly. But you can.

  In the present embodiment, the medical telemeter 100 of the first embodiment described above and the bedside monitor 300 or other medical device are connected by a cable (not shown), and the medical is conducted via this cable. The actuator built in the bedside monitor 300 or other medical device can be driven in accordance with the electrocardiogram signal of the patient acquired by the telemeter 100 for a patient.

  Thus, in the present embodiment, the heartbeat output unit 310 for confirming the patient's pulse by tactile sense is attached to a part of the bedside monitor 300. As a result, the operator presses the heartbeat output unit 310 even for the patient whose biological information is monitored by the bedside monitor, and the tactile sense due to the vibration of the actuator 150 obtained via the heartbeat output unit 310 is obtained. The patient's pulse can be confirmed through stimulation.

  In addition, according to the present embodiment, since the pilot lamp 320 is turned on to indicate the attachment position of the heartbeat output unit 310, even when the bedside monitor 300 stays in the night mode and the screen 330 is turned off. The attachment position of the heartbeat output unit 310 can be easily identified.

  In each of the above embodiments, the actuator has been described as operating only while the microswitch is pressed, but the present invention is not limited to this. For example, when there is a margin in power, the actuator may always be operated.

  In each of the above embodiments, the vibration of the actuator may be switched on and off by switching means that can be switched regardless of whether the actuator is pressed. Even in this case, a certain effect can be obtained in suppressing the driving power of the actuator 150.

  In the above embodiments, the actuator is described as vibrating in synchronization with the R wave of the patient's electrocardiogram, but the present invention is not limited to this. For example, the actuator may be synchronized with the maximum value of the patient's pulse wave or open blood pressure, or may be synchronized with other periodic biological information such as a respiratory waveform instead of the electrocardiogram.
