Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a portable ventilator that assists a patient in breathing when a respiratory arrest occurs, such as in a state of asphyxia or suffocation, or that aspirates and removes a foreign object stuck in the patient's throat. The ventilator of the present invention has functions of insufflation and suction.

[0002]

[Prior art]

 In the event of an emergency, rescue breathing is mostly performed by specialists, and at the accident site, ordinary people can usually request an ambulance. In addition, many of the necessary respirators are specially set at that time, and their handling requires skill and operation by ordinary people is difficult.

[0003] When there is a stoppage of breathing due to asphyxia, etc., there is data that 80% of the people can be revived and life saved by taking recovery measures within 5 minutes. It is well known that is the most important.

[0004] Training and acquisition of artificial respiration techniques are important not only for emergency rescue workers but also for ordinary people. In the past, training of artificial respiration by fire departments and various respirators to assist this have been developed. . Regarding artificial respiration, manual ventilation using hands to perform artificial respiration, artificial respiration in which air is blown into the patient's lungs from the operator's mouth, and oxygen are sent to the patient's trachea by applying light pressure to the trachea The insufflation method, the mask-bag method in which air is supplied to the lungs using a mask and an air bag, the method in which oxygen is supplied to the lungs by applying mechanical pressure using an artificial resuscitator using an oxygen cylinder and a mask, etc. Are known. 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. Currently, they perform mouth-to-mouth respiration and rely on specialists.

[0005] Under such circumstances, on the other hand, portable small and light emergency ventilators that can be used quickly and easily by anyone have also been developed. For example, Japanese Utility Model Registration No. 3045471 “Portable Emergency Ventilator” developed by the applicant of the present application, Japanese Utility Model Application Laid-Open No. 49-151095 “Aid for artificial respiration”, JP-A-63-192455 “Mouse” Two-mouth resuscitation device "and JP-A-2-501444," Respiratory recovery device ".

[0006]

[Problems to be solved by the invention]

 There is no problem if a person present at the accident site where an emergency accident occurs can immediately send air to the patient's lungs to resuscitate without putting a break in time, but a surgeon who is skilled in artificial respiration (specialized) It is rare that a home is conveniently located on the spot, and there is a situation in which everyone is required to take some measure that can easily provide first aid within minutes. Immediately after the occurrence of an accident or the like, anyone who happens to be present by accident is required to develop a ventilator that can easily and efficiently perform artificial respiration, and to have a standing and portable system.

[0007] Furthermore, the above-mentioned conventional instruments and devices are often large in size or require a training in their use, so that not everyone can cope with it in an emergency. In particular, the volume and strength of the breath to be blown in is difficult to understand, and conversely, even when a patient's throat is clogged with a foreign body and inhaled, it is difficult to adjust if it is unfamiliar. It is not an exaggeration to say that hesitation may occur in artificial respiration because he cannot perceive breathing and breathing. In particular, when a foreign object is clogged in the throat, it is necessary to inhale and remove the foreign object, and then artificial respiration is required.

[0008]

[Means for Solving the Problems]

 The present invention provides a pump and a one-way ventilation valve that can mechanically exhaust and inhale, which were not available in the conventional ventilator, so that breathing and breathing at the site can be perceived. It is intended to provide a portable ventilator that can be used by anyone quickly and easily by improving the ease of use.

[0009] The ventilator according to the present invention is a device for assisting "ventilation by mouth", but with a short distance from the patient without direct contact, and with a predetermined distance from the patient to send or inhale air. It is possible to respond while observing the patient's expression. In addition, since air is sent into the lungs through the pneumatic throat directly from the manual pump or the mouth or foreign substances are sucked out from the throat, breathing can be firmly revived.

[0010] Here, the present invention is directed to an insufflation guide nozzle (4) inserted into the mouth of a patient having a palate (1) before and after a manual compression pump (3), and a feeder having a palate (2). Provided is a ventilator provided with a guide nozzle (5) and one-way ventilation valves (9) (9) at the base sides of the guide nozzles (4) (5).

The manual compression pump (3) is made of a synthetic resin such as a flexible silicone resin having an arrow (8) formed on its surface, and sends and sucks a certain amount of air by manual compression and self-restoration. The main body is formed in a bellows shape or the like in order to increase the efficiency of compression and restoration, and the manual compression pump (3) is provided with thin tubes (31) and (31) before and after the main body, and the thin tubes (31) and (31) are provided. One or both of them are connected to tapered tubes (7) (7) having a tapered outer diameter. Note that a tapered pipe (7) may be connected to one side, and a pipe having an outer diameter that is not tapered may be connected to the other side. A blowing guide nozzle (4) is connected to the tip of the tapered pipe (7), and a feeding guide nozzle (5) is connected to the tip of the other taper pipe. The palate (1) (2) has a substantially elliptical shape that covers the periphery of the lips, with the left and right edges curved outward to form a flange, and fitted around the mouth to prevent any air leakage and to close it. It is. 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 (1) (2) can be removed and assembled freely. A nose clip (10) for pinching and closing the patient's nose is connected to the manual compression pump (3) with a string. As the clip (10), a mode in which a nostril is sandwiched by a spring, a substantially V-shaped elastic nosepiece, or the like can be adopted. The manual pump (3) has the function of sending and discharging air, but it is also located at a position where it can be grasped as a grip. Has formed. Since the manual compression pump (3) of a predetermined size is provided, the user can feel the amount and strength of the blow when the air is compressed by grasping the portion.

[0012] The ventilator according to the present invention can send and discharge air by operating the manual compression pump (3), first realize the feeling by using a palm or the like, and then actually perform the operation. It is a respirator that anyone can use easily if they recognize that air can be blown into the air to restore natural respiration. The procedure is as follows: Inject the guide nozzle (4) into the patient's mouth in the direction of the arrow (8), compress the manual compression pump (3) to send air, wait for restoration, take in air, and It is only necessary to compress the manual compression pump (3) and send air. If you have this feeling, you can also see how much you blow in from the feeding guide nozzle (5) on the opposite side. The patient's lungs expand and contract due to body pressure when air is pumped in, so it is only necessary to inhale intermittently with that rhythm. Moreover, since there are one-way ventilation valves (9) and (9), there is no backflow from the patient. Since air is blown into the patient's throat without directly touching the patient's mouth, anyone can easily perform artificial respiration.

[0013]

[Embodiment of the invention]

 Next, an embodiment of the ventilator according to the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the ventilator according to the present invention. FIG. 2 is a side view of the ventilator according to the present invention in an assembled state. FIG. 3 is a partially omitted side view of a mode in which a flexible extension pipe (6) is connected and used. FIG. 4 is an explanatory view of a state in which another suction device (12) is connected to the tapered tube (7) and suction is performed using the ventilator according to the present invention. 5 to 8 are views showing the use of various forms of the ventilator according to the present invention.

The illustrated ventilator comprises a blowing guide nozzle (4) and a palate (2) to be inserted into the mouth of a patient having a palate (1) before and after a fist-sized manual compression pump (3). A guide nozzle (5) for feeding is provided, and one-way ventilation valves (9) and (9) are provided on the root side of the guide nozzles (4) and (5), respectively. Because the whole is made of a translucent flexible material, the movement of the one-way ventilation valves (9) and (9) can be seen, and the air flow can be understood. The manual compression pump (3) is made of a flexible synthetic resin having an arrow (8) formed on its surface, and sends and sucks a certain amount of air by compression and restoration. The manual compression pump (3) is formed in a bellows shape, and is provided with thin tubes (31) and (31) before and after the main body thereof, and one of the thin tubes (31) and (31) has a tapered outer diameter tapered tube (31). 7) is connected. A blowing guide nozzle (4) is connected to the tip of the tapered pipe (7), and a feeding guide nozzle (5) is connected to the tip of the other tapered pipe. The blowing guide nozzle (4) needs to be flexible to a certain extent, and bends freely in the mouth to blow air toward the throat. The blowing guide nozzle (4) has a tapered cylindrical shape with a rounded tip. It is preferable to provide a concave portion at the edge so that the blowing port can be held lightly by being bitten by the front teeth and slightly caught. As the breath passes through the air passage of the manual compression pump (3), the valves of the one-way ventilation valves (9) (9) sway with the breath of breath, obstruction and release can be easily seen and there is no backflow.

Further, the ventilator of the embodiment is devised so that it can be disassembled and can be combined in various ways. As a structure that can be assembled, a one-way ventilation valve (9) (9) is provided in each of the thin tubes (31) and (31) of the manual compression pump (3) provided with thin tubes (31) and (31) in front and behind. Then, the tapered pipes (7) and (7) each having a thin pipe (71) at the tip are externally fitted, and the palate (1) and (2) are fitted into the tapered pipes (7) and (7). And a feeding guide nozzle (5). The manual compression pump (3), one-way ventilation valves (9) (9), tapered pipes (7) (7), palate (1) (2), blow guide nozzle (4), feed guide nozzle ( 5) and 5 are freely disassemble and assemble, and further have a curved thin tube having a medium thin tube which is fitted to the thin tube (71) of the tapered tube (7), extends therefrom, and has the feeding guide nozzle (5) attached to the other end. The flexible extension pipe (6) is connected freely, and the nose clip (10) is connected to the manual compression pump (3) with a string. 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 flexible extension pipe (9) is dimensionally designed so that the palate (1) (2), the blowing guide nozzle (4), and the feeding guide nozzle (5) can be attached to the flexible extension pipe (9). ) Can also be used for artificial respiration.

The palate (1) and (2) are color-coded in different colors, so that it is easy to see whether the blowing guide nozzle (4) or the feeding guide nozzle (5). The palate (1), (2) is used in contact with the mouth of a patient or an operator, 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 (1) and (2), the guide nozzle for blowing (4), the guide nozzle for feeding (5), and the tapered tube (7) are designed to be disassembled and assembled as parts, and are made of synthetic resin such as silicon rubber or vinyl. It is made of soft materials such as wood. The ventilator will not have time to assemble in case of emergency, so it will usually be kept in the assembled finished product.

In the artificial respirator having such a configuration, when performing artificial respiration on a patient, the blowing guide nozzle (4) is inserted into the mouth of the patient. Since the blowing guide nozzle (4) is flexible and has a concave portion at the tip that catches on the teeth, it can be firmly inserted by inserting it. Then, the resuscitation is performed by repeatedly holding the manual compression pump (3) with the hand and compressing and sending air to the patient's lungs. It is optional whether to use a manual compression pump (3) or the operator can chew the tip of the feeding guide nozzle (5) to breathe in, but first grasp the manual compression pump (3). Since the amount and speed of the discharge allow the user to feel the degree of artificial respiration, the user can perform artificial respiration without hesitation. FIG. 5 shows a state of use in an assembled ventilator mainly using a manual compression pump (3), and FIG. 6 shows a state of use in a ventilator further connected to a flexible extension tube (9).

On the other hand, as shown in FIG. 7 and FIG. 8 showing an example of use of the present embodiment, a method of sucking foreign matter from the mouth of a patient can also be used. When using the ventilator for aspiration, the guide nozzle (5) for feeding is inserted into the mouth of the patient before use. It is used in a state opposite to the air blowing, and utilizes the fact that it can be sucked only in the direction of the outlet of the blowing guide nozzle (4) by the operation of the one-way ventilation valves (9) (9). Insert the feeding guide nozzle (5) side as far as the back of the patient's mouth, and if possible, use a nose clip (10) to stop air from entering the nose. More specifically, as shown in FIG. 7, a manual guide pump (3) can be compressed and sucked by inserting a feeding guide nozzle (5) to suck a foreign object clogged in the throat by itself. When a strong suction force is required, a suction device (12), for example, a vacuum cleaner or an electric vacuum cleaner can be connected to the tapered pipe (7) as shown in FIG.

[0020]

 The manual compression pump (3) was made of vinyl resin, the entire body was 20 cm in length, and a bellows-shaped tank part was 8 cm in length and 4 cm in diameter. The tapered pipe (7) had a length of 6 Cm and a tapered portion with a diameter of 3 to 2 Cm. The tube without taper on the other side was 6 cm in length and 2 cm in diameter. The palate (1) and (2) were made of a transparent soft material so that the longitudinal direction was 10 Cm and the width was 5 Cm, they were substantially elliptical, and the left and right sides were slightly curved to fit around the lips. The air blowing guide nozzle (4) was designed to be a tube with a length of 4 Cm and a diameter of 2 Cm at the circular end. The length of 2 Cm can be adjusted by the insertion depth of the tip of the tapered tube (7) into the thin tube (71). The flexible extension pipe (9) was made of a bendable material having a diameter of 2 Cm and a length of 30 Cm. An arrow 8 indicating that the air moves only in one direction is formed on the product. The above is only an example, and specific dimensions and materials are not limited to these.

[Effect of the invention]

 The respirator according to the present invention has the above-described structure, and has the following unique 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 "respirator" of the present invention can basically send the air guided by the guide nozzle from the patient's mouth to the back of the tongue and the tip of the throat directly to the lungs without waste. It assists the most effective method of restoring spontaneous breathing. Since there is no direct contact with the mouth, air can be sent without discomfort and the lifesaving system is expanded. 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 rescue breathing, the present invention can be combined with a flexible extension tube so that, for example, a patient or vehicle under an object can be used. It is also possible to perform artificial respiration from above by inserting it into the mouth of a patient. In addition, when the patient clogs various foreign substances in the mouth, such as the throat with mochi, candy, marbles, etc., or traps dirt in the throat, the ventilator uses a manual compression pump to quickly remove the foreign substances. Can be discharged and discharged. In particular, since it can be sucked by a manual compression pump, it can be operated spontaneously by itself even in the situation of one patient. When a strong suction force is required, it can be connected to a relatively general-purpose suction device such as a vacuum cleaner, so that it can be used in the form of the connection. It can remove foreign objects from the throat and turn the ventilator upside down, then inflate it to perform a series of resuscitation activities. Since two one-way ventilation valves are provided before and after the manual compression pump, there is no backflow from the air or the body once sent to the patient, so that backflow in the vessel can be prevented and infection and odor can be prevented. Anyone can use it easily without danger or filth. All components are assembled and disassembled freely, and the dimensions are designed so that each component can be connected. For example, the two palate can be removed from the manual compression pump and attached to the front and back of the flexible extension pipe, and similarly, the blowing guide nozzle and the feeding guide nozzle are attached to both ends of the flexible extension pipe. The flexible extension tube with palate and guide nozzle at both ends can be used alone for artificial respiration. As described above, the respirator according to the present invention is small and lightweight, has a simple configuration that can be inexpensively manufactured, has the effects of various rescue rescuers as a unit, and can be operated in one touch. Configuration. The components are also dimensional designs that are related to each other, and may be manufactured and provided at low cost. 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 ventilator itself raises awareness of rescue of life, and its practical value is extremely high.
