Description

  The present invention relates to a ventilator used for cardiopulmonary resuscitation and the like.

Conventionally, the rescuer (A) who has fallen into the asphyxia or suffocated state has a method of performing artificial respiration as an emergency measure in which the rescuer (A) and the rescuer (B) directly contact the mouth. Has been used for artificial respiration.
However, artificial respiration by mouse-to-mouse requires a technique and is directly performed by mouth-transfer, so that it has a drawback that there is resistance and there is a possibility of mutual infection of infectious diseases. In particular, new caseoviruses, sars, HIV, and the like, which have recently been regarded as problems, are said to take on the rage, and countermeasures have been regarded as important, and a safe artificial respiration method having a function to prevent them is desired.

In addition, in the conventional method, the face approaches during artificial respiration, so it is difficult to observe the situation of the rescued person (A) as a whole, and the change of the most important rescued person (A) during the rescue is accurately grasped. It is difficult in posture.
In addition, heart massage treatment, which is often performed simultaneously with artificial respiration, must be performed after changing the posture, making lifesaving treatment difficult. Furthermore, the need for an AED (automated external defibrillator), which has become widespread recently, has been strongly recognized and has been placed in public facilities and bullet trains. Therefore, the necessity of a ventilator that can perform treatment by opening both hands at a distance in the case of an artificial respiration treatment that must be performed is strongly desired as an urgent issue.
The artificial respirator of Japanese Patent Application No. 2005-118203 is known, but in this case, the rescuer (B) must operate from the top of the rescuer (A). It has the above-mentioned drawbacks that it is limited and rescue is very difficult, and infection prevention measures such as viruses are not regarded as important, and mutual infection occurs.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention. Details will be described below with reference to the drawings.

Embodiment 1 of the present invention will be described below with reference to the drawings.
FIG. 1 is an overall cross-sectional view of the ventilator 1. FIG. 2 is a schematic view showing a use state of the ventilator 1.

As shown in FIG. 2, the rescuer (A) in a lying state first secures an airway and takes a posture capable of breathing. The mask part 2 of the ventilator 1 is applied in close contact with the mouth of the rescuer (A).
The mask part 2 is closely connected to the main body part 3 of the ventilator 1, and the bellows part 6 is tightly connected to the other of the main body part 3, and the tip of the bellows part 6 is The mouthpiece 7 is formed, and the mouthpiece 7 is brought into a state where the rescuer (B) can bark and supply air.
For the following explanation, the rescuer (B) side is defined as the upstream side, and the rescuer (A) side is defined as the downstream side.

  Since the bellows portion 6 can be bent and used as shown in FIG. 2, the rescuer (B) can take a posture most suitable for rescue. In this state, the rescuer (B) starts the rescue by observing the rescuer (A) 's physical condition such as breathing, facial color, reaction, etc. in detail. In particular, when a heart massage treatment or AED is used, the entire situation can be observed in detail, and in combination with the ventilator 1, a heart massage treatment or an electric shock can be given to the rescuer (A).

Next, the structure of the ventilator 1 of the present embodiment will be described.
As shown in FIGS. 1 and 2, the mask portion 2 is made of a material such as flexible synthetic resin so as to be in close contact with the face of the rescuer (A).
The contact part 2a of the mask part 2 is formed in a shape suitable for a human face.
The main body 3 includes a downstream main body 4 and an upstream main body 5.
The downstream main body 4 is attached to the upper end of the mask portion 2, and is secured and connected by fitting, fitting, screwing or the like, and is configured to be removable.

  One end of the upstream main body 5 is fitted with the downstream main body 4 and is secured and connected by screwing or the like, and is configured to be removable. The other end of the upstream main body 5 is configured such that the bellows portion 6 is similarly fitted and secured with screw connection or the like, and can be removed. A mouthpiece 7 is provided at the other end of the bellows portion 6.

FIG. 3 shows an initial state of the ventilator 1.
Next, the details are explained according to the procedure of use.
When the rescuer (B) holds the mouthpiece 7 and performs intake Ba, the inside of the bellows portion 6 and the upstream main body 5 becomes negative pressure, and the intake valve 8 provided in the intake opening 5a opens, and the fresh Outside air C is filled inside the bellows portion 6 and the upstream main body 5. At this time, in the three-way valve 9 provided in the connecting portion 5 b provided at any position of the upstream main body 5, the air supply portion 9 a is tightly closed by the negative pressure of the upstream main body 5.

  Next, as shown in FIG. 4, when the rescuer (B) performs the air supply Bb, the intake valve 8 is closed as indicated by the arrow due to the positive pressure of the bellows portion 6 and the upstream body 5, and the three-way valve 9 is In the air supply section 9a, the central slit section 9b is opened by the plus pressure of the upstream main body 5, and the air supply Bc is sent to the rescuer (A) via the mask part 2, so that the rescuer (A) Air is sent into the mouth. At that time, the edge portion 9c of the three-way valve 9 moves downward as shown by an arrow to close the communication between the inside of the mask portion 2 and the exhaust portion 10, so that the air supply Bb that has passed through the slit portion 9b is not sent to the exhaust portion 10. Closed state.

As shown in FIG. 5, when the rescued person (A) starts breathing and exhales Aa, the slit portion 9b of the three-way valve 9 is closed in the initial state by the slight positive pressure of the mask portion, and the edge portion 9c is also closed. It moves upstream and enters an initial state, and the exhaled air Aa opens the exhaust valve 12 provided in the exhaust opening 11, and the exhaled air Aa is released to the outside air. At that time, if there is vomit, it is also discharged.
By repeating this operation, the rescuer (A) 's breathing can be restored.

In particular, the size configuration of the ventilator 1 is such that a general average adult-to-child expiratory volume (tidal volume) is 300 to 1000 ml (milliliter) in an adult and 50 to 50 in a child. It is said to be 500 ml.
Therefore, the air supply amount of the rescuer (B) is preferably 50 to 1000 ml (milliliter).
It is important to have a sufficient volume of fresh outside air C filled in the bellows portion 6 and the upstream main body 5. Accordingly, the internal volume V of the bellows portion 6 and the upstream main body 5 is such that, as shown in FIG. 6, the bellows portion 6 has an equivalent diameter D1 (mmφ) and a length L1 (mm), and the upstream main body 5 has a diameter D2 ( mmφ) and L2 (mm), and the internal volume V is V = π × (D1 / 2) ² × L1 + π × (D2 / 2) ² × L2, and V = 50 ml to 1000 ml.
As a result, the air supply Bb of the rescuer (B) is reduced to about 16 to 18% by being sucked once, but is mixed with the outside air C of the internal volume V, and the oxygen concentration is usually required. 18% or more can be secured.

In terms of materials and the like, the mask portion 2 is a soft synthetic resin material such as elastomer resin, silicone resin, sponge, or rubber, or a natural resin such as rubber, or cloth so as to be in close contact with the mouth of the rescuer (A). It is made of a flexible soft material such as cotton. In particular, in the case of an elastomer resin, a material having a formability and flexibility, for example, a resin hardness of 20 to 70 points is selected.
Further, a transparent or semi-transparent material is desirable so that the internal state can be seen.
The main body 3 may be a hard synthetic resin such as polycarbonate resin, polypropylene resin, or ABS resin, or a hard member such as metal, wood, or synthetic paper, or may be a flexible soft material. Similarly, a transparent or semi-transparent material is desirable so that the internal state can be seen.
Further, the main body 3 may be integrally formed without the downstream main body 4 and the upstream main body 5.

The bellows portion 6 is particularly studied in the present invention, and can be a fold-in fixing bellows 6S.
The dimensional relationship of the inclination angle θ2 of the tapered conical tube 6b connected downstream thereof with respect to the inclination angle θ1 of the divergent conical tube 6a on the upstream side of the bellows portion 6 is configured to be increased by at least 0.3 to a maximum of 7 and 0 degrees. . That is, θ2 = θ1 + (0.5 ° to 7.0 °) is set.

When configured in this manner, as shown in FIG. 7, the divergent conical tube 6a can be inverted only at the upper part, and the valley portion D of the divergent conical tube 6a is folded inside the tapered conical tube 6b, so that the position of D ′ Move to.
On the other hand, the trough E on the opposite side is slightly pulled upward and moves, but is located at E ′ without being folded.
When the upper part of the next upstream side divergent conical tube 6a is also inverted, the valley F is similarly folded and moved to the position of F ′. On the other hand, the trough G on the opposite side is slightly pulled upward and moves, but is positioned at G ′ without being folded.
When this folding is repeated, the bellows portion 6 bends and is in a folded and fixed state, so that it can be used while maintaining that state.
Moreover, when pulled with a slight force, the folding returns to the original state and can be restored to the initial state without folding.

Since the shape of the folding fixed bellows 6S is fixed according to the position of the rescuer (B) and is not pulled, a stable posture can be taken.
Normally, in the case of an adult male, the initial state is that the folding fixed bellows 6S is pulled out and used at the maximum volume V 1.

Moreover, when it is desired to reduce the volume V of the bellows portion 6, it can be adjusted by appropriately folding it. For children and girls, the suction force is relatively small, so if the volume V is not reduced, the air supply Bc that reaches the mouth will be weak, and the rescuer (A) will not be able to inhale. This is because the volume V can be appropriately controlled by folding.
In addition, when carrying it, it has a very practical function that can be stored in a small size by folding all the valleys.
The material of the bellows portion 6 is made of a synthetic resin such as flexible polypropylene resin, silicon resin, or vinyl chloride resin.

  The valve bodies of the intake valve 8, the three-way valve 9, and the exhaust valve 12 are made of flexible synthetic resin, metal, etc., and are configured to be able to open and close with a slight pressure. In particular, a flexible silicon resin or an elastomer resin is desirable.

Details are given for each filter.

As for the nanohole filter, as shown in the schematic explanatory diagram of FIG. 11, the size of the virus or bacteria is usually 10 nm (nanometer) or more, so when passing through the nanohole filter, the virus and bacteria are shut out. It has the function of allowing air and moisture to pass through.
However, if the opening is made too small, the pressure loss at the time of ventilation becomes great and air supply becomes difficult. Therefore, the size of the opening is selected according to the situation.

  In addition, the super antibacterial copper fiber filter is a cotton sheet of ultra-fine cordera copper fiber, and copper ions are amplified from the copper fiber by moisture from the mouth to destroy or inactivate influenza virus, pollen and mold. In addition, it is a filter that can perform air antibacterial and sterilization.

  The silver ion water impregnated filter is the filter base material impregnated with silver ion water. By the effect of silver ions, the influenza virus, pollen and mold are destroyed or inactivated. It is a filter that can perform.

  In addition, as an example of the popidone iodine polymerization filter, the trade name “Graft Shut Filter” (registered trademark) is called, and by bonding the popidone iodine used for sterilization of gargles and medical sites to the filter base material. In addition to destroying or inactivating the influenza virus, it has a mouth disinfection effect.

  Similarly, the strawberry extract-impregnated filter has the effect of destroying or inactivating influenza virus, herpes simplex virus, and Staphylococcus aureus by the bactericidal effect of the cocoon extract, which is a natural material, and has a mouth disinfection effect.

  Bactericidal enzyme filters are used in air cleaners for homes, hospitals, etc., and enzymes sterilize influenza A, B, SARS, coronavirus, Staphylococcus aureus, MRSA, tuberculosis, mold, etc. It has a function to activate.

  When a magnetic sterilization filter is used by containing magnetic powder in the filter base material or applying and spraying the magnetic powder on the filter base material, the current generated by magnetism is applied to bacteria, viruses, molds, etc. It produces a bactericidal effect.

Each of the above filters has antibacterial action, antibacterial action, bactericidal action, deodorizing action, etc., and these can also be selected individually or in an optimal combination depending on the rescuer's situation, rescue environment, etc. Can be used.
In addition, other materials having the same effect include that it can be used as the sterilization filter according to the effect.

In addition, an intake filter 20 is provided outside the intake opening to remove dust, moisture, bacteria, and the like from the outside air C, and dust, moisture, and the like are removed from the outside air C so as to be filled as clean outside air C. It has come to be.
