Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a portable ventilator that is used for emergency use in the event of personnel loss, such as in a state of asphyxia or suffocation.

[0002]

[Prior art]

 Conventional artificial respiration is mostly performed in the field of specialists, and ordinary people at the scene of an accident rely only on ambulance requests, and the rest are just struggling. Also, only artificial respirators are set up professionally, and their handling requires skill, and the operation of ordinary people is very difficult.

[0003] When an individual suffers from asphyxia, syncope, or neglect of personal affairs due to an accident, an earthquake, a fire, or other causes, causing a respiratory disorder, the life of the person competes for every second. Inhaling air into the lungs as soon as one second is the only essential lifesaving action. However, according to the data, after 10 minutes of this procedure, 90% of the persons cannot be resuscitated and die. On the other hand, if this is dealt with within 5 minutes, 80% of the people will be revived and saved. Early rescue breathing for asphyxia and shock death is of paramount importance in saving lives. If possible, it is necessary to give artificial respiration within 2 minutes, and a resuscitation method that responds to this request in seconds is required. However, according to the actual data in 1995, the average time from when the ambulance was notified to when it arrived at the site was more than 6 minutes, so about 20% of the lives could not be rescued.

[0004] When an earthquake or a traffic accident or other disaster occurs, or an accident occurs at home or on a construction site, and a patient in a state of asphyxia appears, any one of the persons present there can quickly, easily and effectively use it. If the patient can be ventilated, most of the patient's life will be saved. Training and acquisition of artificial respiration techniques are important, but their spread is still limited.

Conventionally, various artificial respiration methods and artificial respirators have been developed. Manual artificial respiration; a method of artificial respiration using hands. Mouth ventilation; a method of blowing air into the patient's lungs with the surgeon's mouth. Insufflation; A method of delivering oxygen to a patient's trachea under light pressure by tubules. Mask-bag method: A method of sending air to the lungs using a mask and an air bag. Artificial resuscitator: A method of sending air to the lungs by mechanically applying negative and positive pressure with an oxygen cylinder and mask. Such conventional means are classified into means using the skill of the operator and means using instruments. However, in an actual emergency, use a respirator that is fixedly installed in a hospital or ambulance, or, in the event of an accident, etc., emergency rescue workers, their designated persons, and specific persons based on them may directly contact patients. Relies on artificial respiration by mouth. Fig. 6 is a diagram showing artificial respiration using a combination of mouth ventilation and manual ventilation for a lying patient. Has hesitation.

[0006]

[Problems to be solved by the invention]

 The survival rate of human beings during asphyxia / suffocation / personnel aversion is determined by treatment within a short time, and must be within 2 to 10 minutes. After 5 minutes, the survival rate is 20% or less. Even if an ambulance is requested in an emergency, arrivals often take more than 10 minutes due to local conditions such as earthquakes, fires, traffic congestion, and so on. Is lost. This is why it is important that those present at the scene of an emergency should respond immediately to the occurrence of an emergency accident. Air must be pumped into the patient's lungs immediately without a break. However, as shown in Fig. 6, it is rare that an operator (expert) skilled in artificial respiration is conveniently located on the spot, and anyone can take any measures that can easily take emergency measures within minutes. Requested.

[0007] The above-mentioned conventional equipment is installed in an ambulance or a hospital, and the equipment itself is relatively large and requires a training in its use. Not exclusively. The `` artificial respiration by mouth, '' which is a relatively reliable method of artificial respiration, is widely spread due to discomfort, direct contact with the mouth, when there is a distance from the patient under the building, or when the patient's posture cannot be corrected. Is now a step. Thus, immediately after the occurrence of an accident or the like, there is a need for the development of a respirator that allows anyone who is present on the spot by chance to easily and efficiently perform artificial respiration, as well as a standing and portable system.

[0008]

[Means for Solving the Problems]

 The present invention, which meets the above-mentioned demands, is to provide a portable, small and lightweight emergency ventilator that anyone can use quickly and easily.

[0009] The portable emergency ventilator according to the present invention, for example, blows air from a mouth into a patient in a state of asphyxia, and thus basically performs "mouth ventilation". It is an instrument to use. However, since there is no contact with the patient's mouth and there is no need for an electric drive unit and other accessories such as an air bag unit and an oxygen cylinder, it is clean, portable, and simple. Since air can be sent at a predetermined distance from the patient, it is possible to respond while observing the patient's expression. In addition, compared to manual ventilation, air is directly blown into the lungs through the pneumatic throat using the guide nozzle for insufflation.

[0010] Here, the present invention provides an air blowing guide nozzle (4) to be inserted into a patient's mouth or air throat at the tip of a hollow tube (3) provided with palate (1) (2) at the front and back. Another object of the present invention is to provide a ventilator provided with an inlet (5) for sending air (breath) to the other side.

The palate (1) (2) provided before and after the hollow tube (3) has a substantially elliptical shape that covers the periphery of the lips, and its left and right edges are curved outward to form a flange. It is a shape that fits to prevent any air leakage and closes. The palate (1) is provided on the side that sends air to the surgeon's mouth, and the palate (2) is provided on the side that contacts the patient's mouth. The palate (2) which contacts the patient's mouth is further provided with an extension (6) in the form of a nasal mask for closing the nose of the patient, or a clip (7) for pinching and closing the nose. It is preferable to connect them. As the clip (7), a mode in which a nostril is sandwiched by a spring, a substantially V-shaped elastic nose piece, or the like can be adopted. The hollow tube (3) is a passage for sending out air, but since the middle portion may be grasped as a grip, the outer shape is formed to an appropriate thickness. By providing the hollow tube (3) with the palate (1) (2), the work of grasping that part and blowing air can be intuitive, and the palate (1) (2) ) Is fixed, and artificial respiration can be performed safely and smoothly. The inside of the hollow tube (3) has a thin straight tube shape because a large space in which air stays is not smoothed out. The air blowing guide nozzle (4) has a flexible and slightly tapered cylindrical shape, and the blowing port (5) has a short cylindrical shape. A flexible extension pipe (9) can be connected to the blow port (5) at the rear end of the hollow pipe (3).

[0012] The portable emergency ventilator according to the present invention can be easily used by anyone provided that it is provided anyway and is aware that air is blown into the lungs of the patient to restore natural breathing. It is a portable emergency ventilator. All that is required is to insert the air blowing guide nozzle (4) into the patient's mouth and blow air (breath) through the opposite blowing port (5). The patient's lungs expand and contract due to body pressure when air is pumped in, so they need only intermittently inhale at that rhythm. Since air is blown into the patient's throat without directly touching the patient's mouth, anyone can easily apply artificial respiration.

[0013]

[Embodiment of the invention]

 Next, an embodiment of the portable emergency ventilator according to the present invention will be described with reference to the drawings. FIG. 1 is a partially omitted perspective view of the ventilator according to the present invention. FIG. 2 is a partial side view of the hollow tube (3). FIG. 3 is a plan view of a different embodiment of the palate (2). FIG. 4 is an explanatory view of a state in which artificial respiration is performed using the portable emergency ventilator according to the present invention. FIG. 5 is an explanatory view of a state in which the portable emergency ventilator according to the present invention performs artificial respiration using a flexible extension tube connected to the rear end of the ventilator. FIG. 6 is an explanatory diagram of a state where both conventional “artificial respiration by mouth” and “manual artificial respiration” are used together.

In the portable emergency ventilator of this embodiment, a palate (2) is provided at the front and a hollow tube (3) provided with a palate (1) at the rear is inserted into a patient's respiratory throat. An air blowing guide nozzle (4) is provided, a blowing port (5) for sending air (breath) is provided on the other side, and a flexible extension pipe (9) provided with a palate (11) at the blowing port (5). ) Are concatenated. The palate (1) that prevents air leakage from the surgeon's mouth is omitted when connecting the flexible extension tube (9) because the palate (11) is provided at the end of the flexible extension tube (9). You can also. The air blowing guide nozzle (4) needs to be flexible to some extent, and is freely curved in the mouth to blow air toward the throat. The air blowing guide nozzle (4) has a tapered cylindrical shape. The blowing port (5) has a shape in which a short tube is projected, and is provided for blowing over the lips. It is preferable to provide a concave portion (51) at the edge so that the blowing port (5) can be held lightly by being bitten by the front teeth and slightly caught. Further, a tape-shaped ultra-thin film piece (31) is attached to the air passage of the hollow tube (3) so that air can enter and exit the tube. When breath passes through the air passage of the hollow tube (3), the ultrathin film piece (31) shakes with the breath of breath, and natural breathing can be easily seen. By connecting the flexible extension tube (9), the distance to the patient can be increased, and the connection can be made without concern for the orientation and posture of the patient's mouth.

The front palate (2) is used in contact with the patient's mouth, has a substantially elliptical shape covering the periphery of the lips, and is formed with a curve so as to fit around the lips. The palate (2) may be provided with a nasal mask-like extension (6) for closing the nose of the patient as shown in FIG. In order to close the nose, a simple clip (7) may be connected with a string (8). The clip (7) shows a nose clip which clamps a nostril with a spring.

The flexible extension pipe (9) provided with the palate (1) (2), the hollow tube (3), the guide nozzle (4) for air blowing, the blowout port (5), and the palate (11) are each a part. It is made of a flexible material such as synthetic resin material such as rubber or vinyl. A male screw and a female screw are cut at the connection part of each part, and the screw part of each part is screwed together to assemble. It is preferable that the portion to be inserted into the mouth is made of a relatively soft material, and the portion of the palate (2) is made of a transparent or translucent material, since obstruction can be observed. For example, when the patient opens his lips and performs a movement to discharge air, or when the ultra-thin film (31) arranged in the air passage flutters in the opposite direction, the pressing force of the palate (2) can be relaxed. This can release the obstruction, aid in air exhalation, and speed recovery to spontaneous breathing. Of course, the ventilator does not have time to assemble in case of emergency, so it is usually necessary to keep the assembled finished product. Incidentally, instead of combining parts, it is also possible to integrally mold the entire ventilator with synthetic resin using a similar configuration.

[0017]

【Example】

 The hollow tube (3) is made of a vinyl resin tube with a length of 15 Cm and a diameter of 3 Cm. The palate (1) and (2) have a lengthwise direction of 10 Cm and a width of 5 Cm, and have a substantially elliptical shape, and the left and right sides are formed. It was made of a transparent soft material to be slightly curved and fit around the lips. The air blowing guide nozzle (4) is to be inserted deeply into the patient's mouth to the throat, and ergonomic dimensions and shapes are required to allow the blowing air to be smoothly and smoothly sent to the lungs. The tube was designed to be 8 Cm in length and 2 Cm in diameter slightly shorter than the standard length from the lips to the throat. The flexible extension pipe (9) was made of a bendable material having a diameter of 3 Cm and a length of 30 Cm. The actual product is printed with the letters "ventilator" as a display, and a "photograph of the state of use" is affixed to the surface of the hollow tube (3). The above is only an example, and specific dimensions and materials are not limited to these.

[0018]

[Effect of the invention]

 The portable emergency ventilator according to the present invention has the above-described structure, and has the following specific effects. Since it is a very simple configuration that allows you to intuitively use the respirator just by looking at the respirator on site, it can be used by anyone who is not an expert in artificial respiration. In particular, the one in which the photograph of the state of use is pasted as in the embodiment has the advantage that even children can understand the usage correctly and there is no risk of misuse. The "ventilator" of the present invention is basically used for the method of sending air from the patient's mouth, and assists the most effective method for restoring natural breathing. Since there is no direct contact with the mouth, air can be sent without discomfort. The ability to deal with the patient's complexion and breathing while observing it is also excellent. Although the patient is not always in a position or position that facilitates artificial respiration, the present invention provides a flexible extension tube so that, for example, the patient can be inserted into the patient's mouth under the object and It is also possible to give artificial respiration from. As described above, the portable emergency ventilator according to the present invention has a simple configuration that is small, lightweight, and inexpensive. There is simplicity suitable for widespread use without failure during use or misunderstanding of the method of use. Since it is compact, it can be kept at home, at each company or in each company, and can be stored together with other rescue equipment in a disaster response bag. The existence of a portable emergency ventilator itself raises awareness of rescue of life, and its practical value is extremely high.
