[0016]

BEST MODE FOR CARRYING OUT THE INVENTION First, the process leading to the present invention will be described. When an injury or illness occurs in an emergency system, it is important to know the condition of the injury immediately. Therefore, in a public place such as a station building, a school, or a ship, it is preferable to have a living body monitoring device that allows anyone to easily measure the patient's condition before the ambulance arrives at the scene. For example, the monitor device may be mounted on an emergency stretcher installed in a public place. However, since the stretcher is used by being carried manually, the monitor device is required to be extremely small and lightweight. When not in use,
It is required to withstand such handling because it is stored in a container that is rolled or folded.
Furthermore, since the carrier part of the stretcher becomes dirty due to use, it is desirable that it can be removed from the carrier and washed as a whole.

For example, when the technique described in the prior art 1 is applied to a stretcher, it is necessary to arrange the piezoelectric sensor on the platform and the electric signal line. However, since the carrier is made of cloth, when the patient is put on it or when it is rolled up and accommodated in the accommodation box, a large force is easily applied to the piezoelectric sensor and the electric signal line, which may damage the piezoelectric sensor or disconnect the electric signal line. There is a problem that you are invited.

Further, if the technique described in the prior art 2 is to be applied to a stretcher, it is necessary to carry the casing of the measuring instrument together with the stretcher, which is an impediment to emergency work and is not practical.

The stretcher disclosed in the embodiment of the present invention has an air mat for measuring biological information attached to a part thereof. The biological information display device is provided on the carrying rod of the stretcher. Further, the carrier to which the air mat is attached and the carrying rod provided with the biometric information display device can be attached and detached.
Further, the air mat and the biological information display device are connected by a pressure guiding tube. The pressure guiding tube has a detachable structure in the middle.

With such a configuration, the preferred patient carrier disclosed in the embodiment of the present invention is a stretcher that is lightweight when used, does not interfere with emergency work, and can be folded and stored when not in use. Can be provided.

FIG. 1 is an overall image view of a patient carrier according to the present invention. In FIG. 1, (a) is a stretcher type patient conveyance tool, and (b) is a stretcher type patient conveyance tool.

An air mat 1 is attached to a part of a bed on which a patient is placed. The air mat 1 obtains biometric information by pressure fluctuation, and is disclosed as an example of a fluid enclosure. In this fluid enclosure, a fluid such as water or air is enclosed in a bag. The fluid enclosure may be in the form of a pad or in the form of a sheet divided into a plurality of blocks.

The patient transport tool according to the present invention is provided with the biological information display device 2. This biological information display device 2
Are stored in a housing provided in a stretcher of a stretcher or a puller of a stretcher. This biological information display device 2
Has a function of detecting a pressure fluctuation from the air mat 1 via a pressure guiding tube and displaying biological information thereof. The patient may be placed on the air mat 1 and pressure may be applied by the weight of the patient to start measuring the pressure fluctuation.

FIG. 2 shows the configuration of the biometric information display device 2. As shown in the figure, the biological information display device 2 includes a control unit 21, a display unit 22, an operation unit 23, a memory 24, a signal processing unit 25, and a detection unit 26.

The control unit 21 is composed of a microcomputer and the like, and executes a predetermined process by a predetermined control program.

The display unit 22 displays biological information such as heart rate and respiratory rate. The display unit 22 is composed of a liquid crystal panel, a plasma display panel, or the like, and is exposed to the outside of the case of a stretcher or a puller of a stretcher so that the display content can be visually recognized from the outside. There is. In addition, the display unit 22 does not have to be exposed to the outside of the housing as long as a part or all of the housing of the bearer or the puller is transparent or translucent.

The operation unit 23 is composed of buttons, switches, a keypad, etc., and inputs an instruction for operating the biometric information display device 2. For example, the operation unit 23
By operating, the display mode on the display unit 22 can be changed and the power can be switched on and off. The display unit 22 and the operation unit 23 are integrally shown in FIG.
The operation / display unit 28 as shown in FIG.

The memory 24 stores biometric information of the patient detected by the detection unit 26, such as signal-processed biometric information and measurement time information.

The signal processing unit 25 has a function of performing signal processing on the biological information of the patient detected by the detection unit 26. Specifically, the signal processing unit 25 performs signal processing with a bandpass filter and an amplifier corresponding to the frequency band of the signals to be separated. This band-pass filter passes only signals having frequencies matching the frequency band of signals to be extracted, such as heartbeat, respiration, and snoring.

The detection unit 26 detects the biological information of the patient. Specifically, the pressure sensor that detects the pressure fluctuation of the air matte 1 through the pressure guiding pipe corresponds to the detection unit 26.
The pressure sensor, which is an example of the detection unit 26, may be equipped with a microphone to detect voice and detect the presence or absence of snoring.

FIG. 3 is an external view of the operation / display unit 28. In this example, the display unit 22 displays the heart rate and the respiratory rate. The operation unit 23 is also provided with a measurement button, a reset button, and a power button. Press the measurement button to start the measurement, press the reset button to start the reset process, and press the power button to
The power can be switched on and off.

Here, the signal separation processing in the signal processing unit 25 will be described in detail with reference to FIGS. 4 and 5. For example, in the case of breathing, the breathing cycle is determined in advance and only the signal in that frequency band is extracted and used as the breathing signal, although it depends on the individual. The passband for respiration is 0.05-1 Hz. In the case of heartbeat, it is a spike-shaped signal at intervals of about 1 second,
The pass band is about 2 to 10 Hz. A graph showing heart rate and respiratory rate is shown in FIG.

Speech / snoring is a high frequency region, 30-200 Hz. The width of these frequency regions can be set / changed by the data management terminal so that an error does not occur due to individual difference. A graph showing presence / absence of voice / snoring and presence / absence of body movement is shown in FIG.

The body movement appears as a large pressure fluctuation.
Since the absolute value is large, pressure fluctuation occurs in a wide frequency band. Therefore, the body movement is comprehensively determined based on the combination of breathing / heartbeat / voice. The body movement is judged mainly from the signal amplitude.

Whether or not a person is alive depends on, for example, breathing,
Judgment is made based on the factor of whether there is a heartbeat signal. Judgment is mainly based on the power of the signal. In some cases, the judgment is made based on the absolute (gauge) pressure in the air mat 1.

Next, the detailed structure of the patient carrier will be described with reference to the drawings. FIG. 6 is a view of the patient transport tool viewed from the information in the state where the patient is placed. In this example, the patient carrier is a stretcher. FIG. 7 is an AA line of FIG.
It is a figure which shows a cross section. FIG. 8 is an enlarged view of the BB cross section of FIG. 6.

As shown in FIG. 6, the stretcher basically comprises a carrier 3 and a carrying rod 4. The luggage carrier 3 is formed by sewing one end and the other end of a piece of canvas into an endless belt shape. As shown in FIG. 7, two carrying rods 4, an air mat 1 and a pressure guiding tube 11 are arranged in a ring of this endless belt, and an upper cloth 31 and a lower cloth 32 are sewn together to sandwich these structures. It is fixed. The vicinity of the carrying rod 4 is sewn along the longitudinal direction so that it can be separated from the luggage carrier when the carrying rod 4 is pulled in the longitudinal direction. The air mat 1 is formed by heat-melting the periphery of two sheets of flexible synthetic resin sheets to form an airtight seal.

The pressure guiding tube 11 is made of a flexible synthetic resin tube. One end of the pressure guiding tube 11 is the air mat 1
It is fixed so as to communicate with the inside, and is led out to the outside through a space between the upper cloth 31 and the lower cloth 32 of the cargo bed 3. Impulse tube 1
One of the detachable joints is provided at the other end of 1, and is detachably attached to the other of the detachable joints fixed to the carrying rod 4.

As shown in FIG. 8, the carrying rod 4 is formed of a hollow metal tube, and the circuit board 5 is provided inside thereof.
6, operation / display 28, three-pronged pressure pipe 52, air pump 5
3 and the electric motor 54 are fixed. A screw lid is formed at one end of the carrying rod 4, and when this is removed, the carrying rod 4
The dry battery 57 stored in the internal battery box can be replaced. A microcomputer or the like is mounted on the circuit board 56. The operation / display unit 28 is exposed to the outside through the window 27.

Out of the dry batteries generally on the market, even the largest single battery has an outer diameter of about 35 mm and a length of about 60 mm.
By arranging the dry batteries in series so that the longitudinal direction of the dry batteries coincides with the longitudinal direction of the carrying rod 4, it is possible to form the outer diameter of the carrying rod 4 to a thickness suitable for being manually gripped.

The air pump 53 is, for example, the special table 2000-.
It is a non-reversible low-pressure diaphragm pump similar to that disclosed in FIG.
Air is delivered by reciprocating the diaphragm. This type of pump is suitable for miniaturization and can be housed inside the carrying rod 4 having a diameter of about 40 mm as in the present embodiment. Since it has a built-in check valve, air will not flow back to the pump and the pressure will not drop. An air hole is formed in the carrying rod 4 for supplying outside air to the pump.

Incidentally, the air pump having the structure shown in FIG. 9 of the specification of the present application may be used instead of the air pump having the structure disclosed in FIG. 3 of the Japanese Patent Publication No. 2000-517232 and its description. The air pump shown in FIG. 9 uses a cylindrical cam 62 to convert the rotation of the motor 61 into a linear motion to operate the diaphragm unit 63. These motor 61, cylindrical cam 62, and diaphragm unit 63
Is selected such that it fits within the inner diameter of the carrying rod 4. A concrete configuration example of the cylindrical cam 62 is described in “New Edition Machine Element” Machine Element Republishing Committee (published by Science and Engineering Corporation) 19
Disclosed in Fourth Edition, July 10, 1969.

Alternatively, the air pump may be constructed by using a reciprocating solenoid instead of using the rotary motor.

The internal pressure of the air mat 1 may be slightly higher than the atmospheric pressure in the unloaded state (that is, the degree to which the air mat is inflated). The inner volume of the air matte 1 may be extremely small (thickness of about 10 mm when inflated). The air pump 53 consumes a relatively large amount of electric power, but since the internal volume of the air mat 1 is small and the operating time is short, a dry battery can be sufficiently used as a power source. That is, the battery does not run out immediately.

A synthetic resin trifurcated pressure pipe 52 is provided inside the carrying rod 4 to connect the detachable joint 51, the pressure sensor 55 and the air pump 53.

The air mat 1, the pressure guiding tube 11, the detachable joint 51, the three-pronged pressure guiding tube 52, the pressure sensor 55 and the air pump 53 communicate with each other and form a hermetically closed space, and an external force is applied to the air mat 1. At this time, the change in atmospheric pressure is transmitted to the pressure sensor 55 via the pressure guiding tube 11, the detachable joint 51 and the three-pronged pressure guiding tube 52.

Pressure sensor 55 mounted on the circuit board 56
Can use a commercially available electret condenser microphone. In the capacitance type microphone, it is easy to obtain the optimum frequency sensitivity characteristic by appropriately adjusting the volume of the back chamber of the diaphragm and the size of the air vent hole.

For the pressure sensor 55, for example, the configuration of FIG. 3 described as the prior art in Japanese Patent Publication No. 2763896 can be adopted. Further, even when an excessive load is applied, the diaphragm is supported by the electrodes and the displacement of the diaphragm does not increase beyond a predetermined amount, so that the diaphragm is not destroyed. That is, it is not destroyed even by the pressure generated suddenly when the patient is placed on the bed 3.

Next, with reference to FIG. 10, a method of using the patient carrier according to the embodiment of the present invention will be described by taking a stretcher as an example. First, the patient is placed on a stretcher (S1001). Then, turn on the power switch of the operation / display unit 28 (S10).
02).

When the power switch is turned on, the electric motor 54 automatically rotates and air is sent from the air pump 53 to the air mat 1 so that the internal pressure detected by the pressure sensor 55 reaches an appropriate value. 54 stops (S1003).

The measurement result is displayed on the operation / display unit 28 (S1004). Then, after removing the patient, when the detachable joint 51 is removed, the air in the air mat 1 escapes through the pressure guiding tube 11, and the luggage carrier 3 is easily folded (S100).
5).

In the flow shown in FIG. 10, step S1
003 and step S1004 are executed by a program of the control unit 21 including a microcomputer provided on the circuit board 56. The processing flow is shown in FIG.

In FIG. 11, first, the control section 21 determines whether or not the power is on (S1101).
If the result of determination is that the power supply is on, the electric motor 54 rotates and air is sent from the air pump 53 to the air mat 1 (S1102). Subsequently, the control unit 11 determines whether the internal pressure detected by the pressure sensor 55 is equal to or higher than a predetermined value (S1103). If the result of the determination is that the value is equal to or greater than the predetermined value, the electric motor 54 is stopped and the air pump 53 is also stopped accordingly.

Then, by detecting the pressure fluctuation of the air matte 1 by the pressure sensor 55, the measurement of the biological information is started (S1104). Then, the measurement result is displayed on the operation / display unit 28 (S1105).

Here, FIGS. 12 and 13 show how the removable joint is attached and detached. Detachable joint 5 shown in FIG.
In No. 1, the removable joint 51 on the air mat 1 side has a click male plug structure, and the removable joint on the carrying rod 4 side has a click female plug structure. The attachment / detachment is performed through the air inlet, and the stoppers provided on both sides are fitted together. This attachment / detachment structure has a structure similar to a general gas plug.

FIG. 13 shows another example of the attachment / detachment structure. In this example, two pressure guiding pipes 12 and 13 are connected to the air mat 1, and each has removable joints 58 and 59. Each of the removable joints 58 and 59 is connected to the air pump 53 and the pressure sensor 55 via a pressure guiding tube.

In FIG. 14, instead of the biological information display device 2,
It is a block diagram when installing the biometric information transmitter 2a which carries out signal processing of the detected biometric information, and transmits the signal to the biometric information display apparatus etc. which were installed in another place by wireless communication.
The biometric information transmitting device 2a includes a detecting unit 201, bandpass filters 202, 203, 204, amplifiers 205, 2
06, 207, wireless communication processing unit 208, antenna 209
Is equipped with.

The detecting section 201 is for detecting the pressure fluctuation of the air mat 1, and is, for example, a pressure sensor. The bandpass filters 202, 203, and 204 include the detection unit 2
The signal output from 01 is input. This signal is a signal corresponding to the pressure fluctuation. This bandpass filter 2
Reference numerals 02, 203, and 204 pass the frequency bands corresponding to heartbeat, respiration, and snoring, respectively. Although three band pass filters are shown in this example, the number of band pass filters is not limited to this, and an arbitrary number of two or more band pass filters may be used. Although an analog filter is used as the bandpass filter in this example, the invention is not limited to this, and the signal may be separated by a digital filter after A / D conversion of the detection signal. Amplifier 20
5, 206 and 207 are the bandpass filters 20 of the respective
2, 203, and 204, and amplifies the signal passed through each filter. The wireless communication processing unit 208 inputs the signals amplified by the amplifiers 205, 206, and 207, and executes a modulation process for outputting the signals wirelessly. The antenna 209 has a function of converting an output signal from the wireless communication processing unit 208 into a radio wave signal and transmitting the radio wave signal.

The signal transmitted from the biometric information transmitting device 2a is transmitted to the biometric information display device, and the biometric information is displayed and managed on the biometric information display device. For example, this biological information display device is used for ambulances, emergency centers,
It is installed in hospitals.

The air mat 1 has a structure capable of adjusting the internal pressure and has an internal pressure adjusting function (adjusting pump) for setting an initial value before the patient is placed on the bed 3.

The power source may be a rechargeable battery. Further, if the charging terminal is exposed on the surface of the carrying rod 4 and the charging terminal of the carrying rod comes into contact with the power supply terminal on the side of the storing box while stored in the containing box, It is possible to always keep the rechargeable battery in a charged state. Instead of the electric pump for sending air to the air mat 1, a manual pump or a spray can type air filling device may be used.

Furthermore, in addition to displaying the measurement results,
You may transmit to a predetermined place wirelessly. In recent years, an integrated circuit called a "mobile phone chip", in which the communication functions of a mobile phone are integrated on a board of about 7 mm square, has been developed and can be mounted on the circuit board inside the carrying rod 4. If the telephone numbers of emergency hospitals and ambulances are registered in memory in advance, the measurement results will be transmitted via the telephone line.

As described above, by providing the display device for measuring and displaying the biometric information on the stretcher for transportation during the emergency, the biometric information can be grasped without being transported to the ambulance vehicle. The current situation can be judged. As described above, in an emergency, since the biological information can be grasped and the first aid can be taken before the vehicle arrives at the emergency vehicle, it is possible to immediately perform the first aid, which could not be performed by the conventional emergency vehicle. This not only saves the lives of patients, but also lightens the burden on emergency personnel.

Also, by attaching an air mat to a stretcher or the like, the air mat can be easily removed, which facilitates maintenance such as washing and allows compact storage. There is an effect.
