Description

  The present invention relates to an apparatus for inhaling a hydrogen-containing gas as part of a primary rescue procedure for an out-of-hospital patient.

  Most deaths due to heart disease are sudden cardiac deaths that occur out of hospital, and more than 50,000 people die in Japan every year. In view of such current situation, in addition to the improvement of the paramedic system, deployment of an automated external defibrillator (Automated External Defibrillator) to various places, a bystander CPR (CardioPulmonary Resuscitation), present at the site where the patient occurred Measures have been taken, such as training for the practice of cardiopulmonary resuscitation, including chest compressions, artificial respiration and the use of AED, by the general public.

  In recent years, the presence of ischemia / reperfusion injury has attracted attention in relation to myocardial infarction, pulmonary artery embolism, mesenteric artery embolism, post-cardiopulmonary resuscitation encephalopathy, cerebral infarction and the like. Ischemic reperfusion injury is a disorder caused by production of various toxic substances in the microcirculation in the organ or tissue when blood reperfusion occurs in the organ or tissue in the ischemic state. Not only the local but also secondary main organs in the whole body, ie, brain, lung, liver, kidney, etc., may be targeted to cause multiple organ failure. Part of the mechanism is that xanthine oxidase acts on hypoxanthine increased by preceding ischemia and oxygen molecules supplied by blood reperfusion, and active oxygen such as superoxide anion, hydroxy radical and hydrogen peroxide It is produced and leads to cell damage. In particular, it is known that reperfusion with oxygenated blood rather than normal blood results in stronger injury.

  It has already been shown in animal experiments that hydrogen molecules are effective against various diseases and medical conditions, and their effect on humans is also expected. In December 2016, “Hydrogen Gas Inhalation Therapy” was approved as the Ministry of Health, Labor and Welfare Advanced Medicine B 68 (see Non-Patent Document 1 below). This is for adults who continue to have coma even after resumption of their own heart rate after adult out-of-hospital cardiac arrest, in an intensive care unit for 18 hours, 2% hydrogenated oxygen (2% hydrogen, 48% oxygen, 50% nitrogen) And harmonize harmful substances in the patient's body with hydrogen, thereby reducing brain damage in post-cardiac arrest syndrome and thus enhancing the possibility of reintegration after recovery. It is intended.

  In addition, research to investigate experimentally the merits and risks of hydrogen water administration for human acute cerebral infarction (refer to the non-patent document 2 below) and safety for hydrogen containing gas aspiration treatment for human acute cerebral infarction patients. Basic research on measurement of physiological parameters and blood hydrogen concentration (see Non-Patent Document 3 below), combined use of Edaravone alone and Edaravone and hydrogen together with the brain protective agent Edaravone, which is a hydroxy radical scavenger in clinical trials of human acute cerebral infarction There is also a study (see Non-Patent Document 4 below) etc. in which the effect of is compared with the MRI index.

  In order to increase the survival rate and discharge rate of patients generated out of hospital, it is desirable to initiate primary rescue measures for patients as early as possible. In today's Japan, it takes about five minutes to a sufficient time between the request for ambulance dispatch and the time the ambulance arrives at the patient's location. In the meantime, taking action on the patient will increase the chances of reducing the patient's survival as well as the sequelae.

  The above-mentioned advanced medical treatment "Hydrogen gas suction therapy" is performed exclusively in the intensive care unit of a hospital. At present, there is no idea at all to supply patients with hydrogen outside the hospital.

  The present invention seeks to provide an apparatus suitable for inhaling hydrogen-containing gas as part of a primary rescue procedure for patients generated outside the hospital.

  In the present invention, the device is installed at the same place as or in the vicinity of other devices or instruments used in the primary rescue procedure for patients generated outside the hospital, and generates hydrogen for inhalation to the patient. Use of a supply that is stored or stored, an inhaler that directs the patient's gas containing hydrogen out of the supply to the patient's mouth or nose to be inhaled, and other devices or devices. Switching from the non-use state that disables the supply of hydrogen from the feeder to the inhaler and the switching from the non-use state that enables the supply of hydrogen from the feeder to the inhaler, in association with the act of starting A hydrogen-containing gas suction device comprising the mechanism was constructed.

  The supply vessel is a chemical reaction formula that generates hydrogen by reacting water and a reactant that reacts therewith and causing them to react in the usable state, or hydrogen by water electrolysis in the usable state Or a cylinder (or tank) type which stores a gas containing hydrogen in advance and discharges the gas in the usable state.

  The other device or device is, for example, an automatic external defibrillator (AED), and the hydrogen-containing gas inhalation device (the feeder and the inhaler) according to the present invention is housed in the same housing case as the AED. obtain.

  Preferably, the dispenser and the inhaler have a size and weight that can be carried by one hand.

  More specifically, when the user opens the door or lid of the storage case containing the feeder and the inhaler, the switching mechanism is driven by the non-operation of the feeder. The use state is switched to the available state.

  Alternatively, the switching mechanism is in the non-use state by an action exerted on the feeder due to an operation of the user taking out the feeder and the inhaler from the storage case containing the feeder and the inhaler. To the enabled state.

  According to the present invention, it is possible to realize an apparatus suitable for inhaling hydrogen-containing gas as part of the primary lifesaving measures for patients generated outside the hospital.

Sectional drawing which shows the switching mechanism of the hydrogen containing gas suction device of the embodiment.

  One embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the hydrogen-containing gas suction device 0 in the present embodiment is installed at the same location as or in proximity to other devices or instruments 4 used for the primary rescue operation for patients generated outside the hospital. Be done. It is then used outside the hospital to immediately start inhaling the hydrogen-containing gas to the patient immediately before the ambulance, paramedic or doctor arrives at the site. Inhalation of hydrogen-containing gas is performed, for example, on patients who have caused myocardial infarction, pulmonary artery embolism, mesenteric artery embolism, post-cardiopulmonary resuscitation encephalopathy, cerebral infarction, etc. The aim is to reduce cell damage by counteracting the generated reactive oxygen species.

  The other devices or devices 4 described above are typically AEDs, but other examples include stretchers or stretchers for transporting patients, medicines, bandages, response to trauma, hemostasis and other treatments First-aid kit containing medical instruments used in, thermoregulator for hypothermia (brain hypothermia), etc. The brand name "Co-Dek Coeur" is known as one of the thermoregulators for hypothermia (Reference URL: http://www.okayama-u.ac.jp/tp/release/release#id166 .html). This is to insert a cooling cuff from the patient's mouth toward the pharynx, supply cooling water 10 to the cooling cuff and exchange heat with the blood flow near the pharynx to lower the temperature of the patient's brain. It is expected that in the future, small or portable devices that can be deployed anywhere, such as the AED 4, will be developed. The present hydrogen-containing gas inhalation device 0 is assumed to be used for patients in which cardiopulmonary resuscitation is required, and therefore has high affinity with AED4.

  As shown in FIG. 1, in the hydrogen-containing gas inhalation device of the present embodiment, a supply device 1 generating or storing hydrogen for inhalation to a patient, and a gas containing hydrogen discharged from the supply device 1 From the feeder 1 to the inhaler 2 associated with the operation performed to start the use of the inhaler 2 which brings it close to the patient's mouth or nose to cause the patient to inhale, and the other devices or instruments 4 described above A switching mechanism is provided that switches from a non-use state that disables the supply of hydrogen to 2 to a usable state that enables the supply of hydrogen from the supply device 1 to the inhaler 2.

  The type of the supply device 1 includes a chemical reaction formula that generates water by encapsulating water 10 and a reactant 13 that reacts with the water, a water electrolysis system that generates hydrogen by water electrolysis, and hydrogen There is a cylinder type which stores the gas containing and discharges the gas.

  As shown in FIG. 2, in the chemical reaction type supply device 1, the space in the container 11 is divided into a plurality of regions by the partition 12, the reactant 13 in one region and the water in the other region ( Sterilized water is preferred) 10 is stored. Then, a part of the partition wall 12 is broken or opened to mix the reactant 13 and the water 10 in the container 11 to cause a reaction between the two to generate hydrogen molecules. Specific examples of the reactant 13 include magnesium hydride (maghydrogen), calcium hydride, metal magnesium, metal calcium, metal aluminum, metal zinc, metal nickel, metal cobalt and the like. In addition, citric acid and other acids, magnesium hydroxide, calcium hydroxide and other bases may be added for the purpose of acidifying or alkalizing the water 10 that reacts with the reactant 13.

  When starting to use the hydrogen-containing gas suction device 0 equipped with the chemical reaction type feeder 1, for example, the user performs an operation of deforming so as to squeeze or compress the elastically deformable container 11. Conceivable. As a result, pressure is applied to the partition 12 in the container 11 to mechanically break the partition 12 and create a state in which the water 10 and the reactant 13 mix together. In this case, hydrogen gas is generated in the supply device 1 and the hydrogen gas is discharged from the discharge port of the container 11. Alternatively, the user may hit the container 11 against a wall, floor, ground, or the like to impact the partition wall 12 in the container 11 and cause the partition wall 12 to be broken.

  The water electrolytic type supply device 1 applies a voltage to water (preferably sterile water) 10 stored in the container 11 to electrolyze the water 10 and generate hydrogen molecules at the cathode 14. The water electrolysis type supply device 1 may be one performing alkaline water electrolysis as shown in FIG. 3 or one performing solid polymer type water electrolysis as shown in FIG. 4. In alkaline water electrolysis, a voltage is applied to an electrolytic solution in which sodium hydroxide, potassium hydroxide, sodium chloride or the like is added to water 10 in advance. A porous material diaphragm 16 is disposed between the cathode 14 and the anode 15. On the other hand, in the solid polymer type water electrolysis, the same membrane electrode assembly (MEA) 14, 15, 17 as in the solid polymer fuel cell is formed, and between the electrolyte membrane 17 and the electrodes 14, 15. No gap exists, and the distance between the cathode 14 and the anode 15 is very close.

  The hydrogen-containing gas suction device 0 equipped with the water electrolytic type supply device 1 has a battery 183 as a power source and / or has a plug that is inserted into a plug receptacle of an electric power line or other external power source. It has a power cord for receiving power supply from an external power supply. Note that the supply device 1 of the hydrogen-containing gas suction device 0 shares the power supply battery with the AED 4, that is, does not prevent the supply of power from the battery of the AED 4.

  When starting to use the hydrogen-containing gas suction device 0 equipped with the water electrolytic type supply device 1, for example, the user operates the switch of the operation panel, and the electrode is immersed in the water 10 in the container 11 14 and 15 start to be energized. In other words, hydrogen gas is generated in the supply device 1 by water electrolysis, and the hydrogen gas is discharged from the discharge port of the container 11.

  As a matter of course, in order for the water electrolytic feeder 1 to generate hydrogen gas, the electrodes 14 and 15 need to be in contact with the water 10. A water electrolysis apparatus in which the water 10, the electrodes 14, 15, the diaphragm 16 or the electrolyte membrane 17 are enclosed so that the electrodes 14, 15 are immersed in the water 10 even if the container 11 is tilted or rolled over. It is preferable that the hydrogen generator be attached to a weight and be supported by the container 11 via a gimbal mechanism or the like so that the water electrolysis device always takes a fixed posture in the container 11.

  The cylinder type supply device 1 stores hydrogen gas in the container 11 or hydrogen gas mixed with oxygen and nitrogen gas in an appropriate ratio, for example, 2% hydrogen, 48% oxygen, 50% nitrogen store. That is, in the cylinder type supply device 1, hydrogen molecules to be supplied to the patient are already present before use. However, the hydrogen content of the gas to be inhaled by the patient is not limited to 2%, and may be smaller or larger.

  When starting the use of the hydrogen-containing gas suction device 0 equipped with the cylinder type supply device 1, for example, the user can perform an operation of opening the valve to allow the gas stored in the container 11 to flow out from the discharge port. Let's do it. Of course, also in the hydrogen-containing gas suction device 0 equipped with the water electrolytic or chemical reaction type supply device 1, the user may cause the gas to flow out from the discharge port of the container 11 by performing the operation of opening the valve. .

  When the supply device 1 is a chemical reaction type or a water electrolysis type, hydrogen gas is discharged from the discharge port of the container 11, mixed with air or air, and then inhaled by the patient. When the supply device 1 is a cylinder type, hydrogen and oxygen as components of air can be stored in advance in the container 11 together with the mixed gas discharged from the discharge port of the container 11 as it is. It can be inhaled by the patient.

  For example, as shown in FIG. 5, the inhaler 2 is mounted so as to cover the patient's nose and mouth, and is inserted into the patient's nasal cavity as shown in FIG. It is a nasal cannula that guides the hydrogen containing gas into the nasal cavity. When artificial respiration is performed in primary life support, a nasal cannula may be more convenient than a face mask. The length of the tube 21 through which the hydrogen gas supplied from the supply device 1 flows, which connects the discharge port of the supply device 1 to the face mask or the nasal cannula, is optional, and may be much shorter or nonexistent There is sex. The tube 21 is preferably made of a material that makes it difficult for hydrogen to leak or diffuse, or it is preferable that a treatment (such as an aluminum coating) be performed to suppress the leak of hydrogen. A filter for removing by-products other than hydrogen gas discharged from the supply device 1 (especially, chemical reaction type) or a patient's inhalation in the vicinity of the discharge port of the supply device 1 or the tube 21 is used. A deodorizer may be installed to deodorize the gas.

  And, it is desirable that the dispenser 1 and the inhaler 2 have a size and weight which can be carried by one hand.

  There are various conceivable specific aspects of the switching mechanism. Hereinafter, specific modes of the switching mechanism will be listed. First, as shown in FIG. 1, the feeder 1 and the inhaler 2 of the hydrogen-containing gas suction device 0 are housed in the same storage case 3 as the other device or instrument AED 4 or in the same storage case 3 However, in the case of being housed in a storage case placed at a position close to the installation place of the AED 4, the door or lid 31 for opening and closing the storage case 3 can be the switching mechanism. In addition, the size of the storage case 3 may be smaller than that of the illustrated example (in particular, the size can be carried by one hand). When the door or lid 31 of the storage case 3 is closed, the user can not take out the supply device 1 and the inhaler 2 of the hydrogen-containing gas suction device 0 from within the storage case 3 and as a natural consequence, the supply device Operation to start supply of hydrogen gas from 1 to the inhaler 2, ie destruction or opening of the partition 12 in the container 11, ON operation of a switch to start energization for electrolysis, opening of a valve, etc. Can not do. That is, the hydrogen-containing gas suction device 0 is not in use. And if the user who is going to take out the feeder 1 and the inhaler 2 of the hydrogen-containing gas suction device 0 together with the AED 4 opens the door or lid 31 of the storage case 3, the feeder 1 and the inhaler 2 can be operated. It becomes. That is, the hydrogen-containing gas suction device 0 is ready for use.

  When the control circuit (which may be a microcomputer system) 18 is mounted on the supply unit 1 and the control circuit 18 controls the discharge of hydrogen gas from the supply unit 1, the control circuit 18 functions as a switching mechanism. Can carry The control circuit 18 controls, for example, energization of the electrodes 14 and 15 in the water electrolytic type supply device 1, and a valve (solenoid valve) provided in the vicinity of the discharge port of the supply device 1 or in the supply device 1. In some cases, the hydrogen gas is not discharged from the discharge port of the supply device 1 or not discharged. The valve may block / open the inside and the outside of the feeder 1, and between the area where the reactant 13 is stored and the area where the water 10 is stored inside the chemical reaction type feeder 1. It may be shut off / opened.

  Then, the fact that the door or lid 31 of the storage case 3 is opened is sensed by some means, and the control circuit 18 is switched from the non-use state to the usable state based on detection of the fact. can do. For example, as shown in FIG. 7, an optical sensor 181 for sensing ambient light or outside light outside the storage case 3 is connected to the control circuit 18, and the door or lid 31 of the storage case 3 is opened. On the condition that ambient light or ambient light incident on the light source is detected, the control circuit 18 can energize the electrodes 14 and 15 or open the valve. Alternatively, a magnet is attached to the door or lid 31 of the storage case 3 and a reed switch or other magnetic sensor 181 is connected to the control circuit 18, and the distance between the magnet and the magnetic sensor 181 is changed via the magnetic sensor 181. That is, it may be detected that the door or lid 31 is opened.

  As shown in FIG. 8, the fact that the door or lid 31 of the storage case 3 is opened is detected by an optical, magnetic, mechanical, etc. sensor 182 attached to the storage case 3 and the sensor 182 is controlled. It is connected to the circuit 18 so as to be able to transmit and receive signals wirelessly or by wire, and the control circuit 18 can energize the electrodes 14 and 15 under the condition that the opening of the door or lid 31 is detected through the sensor 182. Or, it may be possible to open the valve.

  The operating force applied to the door or lid 31 to open the door or lid 31 of the storage case 3 can be transferred to any kind of transmission mechanism (wire or chain, rod, gear motor, winding gear, pneumatic cylinder or hydraulic cylinder, magnet , Mechanical force, etc.) to transmit to a switch (hermetic limit switch etc.) that is switched by receiving mechanical force, the switch is connected to the control circuit 18, and the door or lid 31 is opened. It is also conceivable that the control circuit 18 can energize the electrodes 14 and 15 or open the valve on condition that the switch has been switched.

  Alternatively, the fact that the hydrogen-containing gas suction device 0 has been taken out of the storage case 3 together with the AED 4 is sensed by some means, and the control circuit 18 changes from the non-use state to the usable state based on detection of that fact. It is also possible to switch. The hydrogen-containing gas suction device 0 is taken out of the storage case 3 for an optical sensor that detects ambient light or outside light outside the storage case 3 and a sensor that detects the magnetism of a magnet attached to a predetermined position in the storage case 3. It can be a means to detect isolated facts.

  As a means for detecting the fact that the door or lid 31 of the storage case 3 is opened or the fact that the hydrogen-containing gas suction device 0 is taken out of the storage case 3 with the AED 4, the storage case 3 or its door or lid 31 and hydrogen Ultrasonic sensor (ultrasound radar) that detects a change in relative positional relationship with the contained gas suction device 0 (in particular, the feeder 1), or that the human body approaches the hydrogen-containing gas suction device 0 A human sensor (passive infrared sensor) or the like may be adopted.

  A mechanism similar to a standing light installed in an accommodation facility or a house can also be adopted. In the example shown in FIG. 9, the supply unit 1 is held by a pedestal provided in the storage case 3 (the inner wall, floor, etc. of the storage case 3), and the hydrogen-containing gas suction device 0 is stored together with the AED 4 An insulator that cuts off the circuit that electrically connects the control circuit 18 and the power supply battery 183 by the user who is trying to take it out of 3 moving it from its installation location, in particular removing the feeder 1 from the pedestal 32 is withdrawn from the feeder 1 and the control circuit 18 is energized to switch the control circuit 18 from the non-use state to the usable state. The insulator 32 may be attached to the door or lid 31 of the storage case 3 and the insulator 32 may be pulled out of the feeder 1 when the door or lid 31 is opened.

  A mode is also conceivable in which the AED 4 and the hydrogen-containing gas suction device 0 are interlocked. That is, the control circuit on the AED 4 side and the control circuit 18 on the hydrogen-containing gas suction device 0 side are communicably connected wirelessly or by wire, and when the AED 4 is activated, a signal indicating that is sent from the control circuit on the AED 4 side The control circuit 18 on the side of the contained gas suction device 0 is sent to the control circuit 18 on the side of the contained gas suction device 0, and the received control circuit 18 on the side of the hydrogen containing gas suction device 0 is switched from the nonuse state to the usable state.

  It is also possible to configure a physical or mechanical switching mechanism that does not depend on the control circuit 18. For example, an external force acts on the feeder 1 due to the operation of opening the door or lid 31 of the storage case 3 containing the feeder 1 and the inhaler 2 of the hydrogen-containing gas suction device 0, and as a result, The non-use state in which the supply of hydrogen from the vessel 1 to the inhaler 2 is disabled may be switched to the usable state in which the supply of hydrogen from the feeder 1 to the inhaler 2 is enabled. More specifically, to transmit the operation force applied to the door or lid 31 to open the door or lid 31 of the storage case 3 (a pin for pushing the feeder 1 or being inserted into the feeder 1, Are transmitted to the feeder 1 via a rod or the like), and the operation force destroys the partition 12 in the chemical reaction feeder 1, opens a valve associated with the feeder 1, or The fasteners which are restrained so as not to open the valve are released to make the valve openable. In this case, the transmission mechanism that transmits the operation force applied to the door or lid 31 of the storage case 3 to the feeder 1 constitutes a switching mechanism. The feeder 1 housed in the storage case 3 is supported in a floating state in the case 3 and the feeder 1 floated due to the operation of opening the door or lid 31 of the storage case 3 falls. It is also conceivable that shock is applied to the feeder 1, thereby breaking the partition 12 in the feeder 1, opening the valve, or detaching the clasp that restrains the valve to make it possible to open the valve.

  Alternatively, an external force acts on the feeder 1 due to the operation of bringing the feeder 1 and the inhaler 2 housed in the housing case 3 together with the AED 4 out of the housing case 3, and as a result, use from the non-use state It may be switched to the possible state. For example, a fastener or other member is assembled to the feeder 1, and this member is anchored to the storage case 3 via a wire or a chain, and the user brings the feeder 1 out of the storage case 3 A member anchored to the case 3 detaches from the feeder 1, and the detachment of the member breaks the partition wall 12 in the feeder 1, opens the valve, releases the restraint of the valve, and enables the valve to be opened. It is conceivable that

  In this embodiment, the device is installed at the same place as or in the vicinity of other devices or instruments 4 used for the primary life support for patients generated outside the hospital, and hydrogen to be inhaled by the patient is taken. A feeder 1 generating or storing, an inhaler 2 for bringing the gas containing hydrogen discharged from the feeder 1 into the vicinity of the patient's mouth or nose to be inhaled by the patient, and the other devices Or hydrogen accompanying the supply device 1 to the inhaler 2 accompanying operations (operation of opening the door or lid 31 of the storage case 3, bringing it out, activation of the AED 4, etc.) performed to start the use of the device 4 The hydrogen-containing gas suction device 0 is provided with a switching mechanism that switches from the non-use state that disables the supply of hydrogen to the usable state that enables the supply of hydrogen from the supply device 1 to the inhaler 2.

  According to the present embodiment, it is possible to start treatment for allowing the patient to inhale the hydrogen-containing gas immediately on site as part of the primary lifesaving measures for the patient generated outside the hospital. Therefore, it is possible to reduce damage to the patient during the time until the ambulance, paramedic or doctor arrives at the site, and in particular, it is possible to suppress damage due to harmful substances such as active oxygen generated at the time of resuscitation. And it can be expected to contribute to the improvement of the survival rate of the patient, the alleviation of the sequelae, the improvement of the QOL (Quarity Of Life) and the control of the medical expenses. Inhalation treatment of hydrogen-containing gases may also have indications for symptoms, diseases, and diseases other than post-cardiac arrest syndrome. For example, there are papers that suggest that hydrogen can be incorporated into the body of a severe burn patient to reduce the damage to organs (kidney, liver, etc.).

  When the other device or device is the AED 4 and the feeder 1 and the inhaler 2 are housed in the same storage case 3 as the AED 4, when a patient who needs cardiopulmonary resuscitation is generated The present hydrogen-containing gas suction device 0 can be used promptly together with AED 4.

  Since the feeder 1 and the inhaler 2 have a size and weight which can be carried by one hand, they can be easily carried to the site where the patient originates, and an ambulance for transporting the patient It is also possible to carry in as it is and continue the inhalation of the hydrogen-containing gas.

  The hydrogen-containing gas suction device 0 of the present embodiment has some effect on the feeder 1 due to the user opening the door or lid 31 of the storage case 3 housing the feeder 1 and the inhaler 2. As a result, any action is exerted on the feeder 1 due to the operation that the user takes out the feeder 1 and the inhaler 2 from the storage case 3 containing the feeder 1 and the inhaler 2. Thus, the switching mechanism switches from the non-use state to the usable state.

  The present invention is not limited to the embodiments detailed above. The specific configuration of each part can be variously modified without departing from the spirit of the present invention.
