  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a portable ventilator according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic sectional view for explaining an embodiment of the portable ventilator of the present invention. 2 is a cross-sectional view of the main part of the embodiment of the portable ventilator of the present invention in which the rescuer is in a pressurized state, and FIG. 3 is a diagram of the rescuer side of the embodiment of the portable ventilator of the present invention in a negative pressure state. FIG. 4 is a side view of the essential part of the portable ventilator according to the embodiment of the present invention with the bellows tube contracted.

  That is, the check valve 1 with a bacteria filter of the portable ventilator of the present invention comprises an upper casing 2, a lower casing 3, a rescuer side opening filter 4, an exhaust hole filter 5, and a ventilation check valve 6. It consists of.

  The upper casing 2 has a rescuer side opening 2a projecting in a cylindrical shape connected to an outside air check valve 6 to be described later at one end, and an upper casing step portion bulged in a flange shape at the other end. In addition, an upper casing connecting portion 2c is extended on the outer periphery of the upper casing step portion 2b. The upper casing connecting portion 2c is screwed with a screw for screwing with a lower casing connecting portion 3d described later. It is something that is set up.

  Next, the lower casing 3 has a rescuer side opening 3a projecting in a cylindrical shape connected to a rescuer mask 9 to be described later at one end, and a lower casing step portion in a flange shape at the other end. 3b is bulged, an exhaust hole 3c is opened in the lower casing step 3b, and a lower casing connecting portion 3d is extended on the outer periphery of the lower casing step 3b to connect the upper casing. A screw to be screwed with the portion 2c is screwed.

  Next, the rescuer side opening bacterial filter 4 is attached to the upper casing step 2b so as to shield the rescuer side opening 2a, and is locked by a locking member from below. It is intended to filter the rescuer's exhalation.

  Further, the exhaust hole bacterial filter 5 is formed in a donut shape and is placed on the lower casing step 3b so as to shield the exhaust hole 3c, and filters the breath of the rescued person.

  Further, in the embodiment, the check valve 6 for ventilation forms a bellows 6b that is recessed in a valley shape at the center, the tip of the bellows 6b forms a cut opening 6c in a linear shape, and the base of the bellows 6b is A flange-shaped check valve for venting that allows the lower casing step 3c bulged into a flange shape to freely contact or separate, that is, opens and closes the exhaust hole 3c opened in the lower casing step 3b. Further, an annular portion 6e is formed in a short cylindrical shape along the lower casing connecting portion 3d on the outer periphery of the ventilation check valve rod portion 6d, and further, the upper casing connecting portion 2c is formed. And a lower casing connecting portion 3d is a film-like one made of a soft synthetic resin, rubber, or the like, which is integrally formed with an outer peripheral edge portion 6a.

  The ventilation check valve 6 is disposed so as to separate the upper casing 2 and the lower casing 3 from each other. When the upper casing 2 is pressurized, that is, when the rescuer performs exhalation, the rescuer side opening 2a and the covered valve are covered. The rescuer side opening 3a is in a communicating state, and air is sent from the rescuer side to the rescued person side. In this state, the ventilation check valve 6d of the ventilation check valve 6 Thus, the pressure is applied and the exhaust hole 3c is closed.

  Next, when the upper casing 2 becomes negative pressure, that is, when the rescuer inhales, the rescuer side opening 2a and the rescuer side opening 3a are closed by the ventilation check valve 6, and the rescuer By connecting the outside air check valve 7 to the side opening 2a, the outside air flows in from the outside air check valve 7, and the rescuer sucks fresh outside air.

  Next, when the lower casing 3 is pressurized, that is, when the rescuer performs exhalation, the rescuer side opening 2a and the rescuer side opening 3a are closed, and the check valve 6 for ventilation is used. Is lifted upward from below, and the exhaled air on the rescuer side is exhausted from the exhaust hole 3c and released to the outside air in the atmosphere.

  Furthermore, the check valve 7 for outside air is connected to the rescuer side opening 2a of the check valve 1 with the bacteria filter and takes in outside air. That is, the check valve 7 is closed when the rescuer performs exhalation. It is opened when inhaling, and the rescuer can inhale fresh outside air without inhaling the exhalation of the rescued person.

  Furthermore, the bellows tube 8 is formed of a flexible resin such as a synthetic resin so as to be stretchable and connected to the check valve 7 for the outside air. It can be held compactly in a state where it is laminated, and can be bent and stretched freely. It can be used in a stretched state or in a shortened state, and a rescuer can be heard at the tip. The mouthpiece 8a is attached.

  With the above configuration, when the rescuer inhales, the outside air is sucked from the outside air check valve 7 via the bellows tube 8, so that at the end of the inhalation, the inside of the bellows tube 8 is outside air (oxygen 21). %, Carbon dioxide gas 0%), and then when the rescuer blows into the rescued person, the bellows tube 8 is filled with a gas having a high oxygen concentration and a low carbon dioxide concentration. It is.

  The rescuer side opening 3a of the check valve 1 with the bacteria filter is connected to an oblique position above the rescuer mouse 9, which makes the rescuer's posture easier and makes other heart massages, etc. The treatment can be performed at the same time, and furthermore, it is easy to accurately capture the face of the rescued person from the viewpoint.

  In other words, since the mask connection port used in the past is located above the mask, the use of this prevents the rescuer's view from being disturbed by the check valve with a bacterial filter having a flange, so that the rescuer can pass through the mask. Although it was not possible to confirm that the mouth of the rescuer was observing and confirming the presence or absence of vomiting, or that the breathing of the inside of the mask was clouded by the breath of the rescuer, in the present invention, The rescuer-side opening 3a of the check valve 1 with a filter is connected to an oblique position above the rescuer mouse 9, so that the check valve 1 with a bacterial filter does not interfere with the view of the rescuer It is.

  Further, since the telescopic bellows tube 8 is used, the rescuer can position his / her face directly above the rescued person.

  The present invention is a portable respirator that can be carried, and is intended to provide a mouse-to-mouse artificial respiration operation to a rescued person who has fallen into a dead or suffocated state due to an accident or the like.
