Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a portable emergency ventilator which allows anyone who is in a state of asphyxia due to an accident, water shortage, etc. to perform artificial respiration.

[0002]

2. Description of the Related Art When a person is fainted and becomes asphyxic due to an accident, water shortage, earthquake, fire or other causes, and breathing and / or heartbeat is stopped, air is supplied into the lungs as soon as one second. And that delay is literally life-threatening.

[0003] Conventionally, in the case of such emergency rescue breathing, the practitioner sends air directly into the patient's mouth by mouth, or intermittently presses the chest by hand to create negative or positive pressure in the thorax. Are alternately generated, that is, a method relying on the skill of a practitioner.

In addition, experts use machines, instruments, oxygen cylinders, etc., such as sending air to the patient's lungs using a mask and an air bag, or sending oxygen to the patient's trachea with a small pressure by applying a small pressure to the patient's trachea. There are ways.

[0005] However, the method relying on the skill of the practitioner does not necessarily mean that the person present at the site is familiar with artificial respiration, and that the air supply by mouth is hesitant to carry out. However, when there is a distance between the patient and the patient under the building, or when the posture of the patient cannot be corrected, the operation cannot be performed.

On the other hand, a method using a machine or an instrument is possible after a patient is transported to a hospital by an ambulance, and is not feasible at a normal accident site because there is no machine or instrument in the first place.

Accordingly, the present applicant has filed a utility model registration No. 30.
No. 45471 has proposed a new portable emergency ventilator (hereinafter simply referred to as a ventilator) that can be carried anywhere with a simple structure.

This ventilator is constructed by connecting a flexible extension tube to the other end of a hollow main body tube having a flange-shaped palate portion and a guide nozzle connected to one end, and one end of the main body portion. After the guide nozzle is inserted between the palate and the tongue of the patient to secure the airway, air is blown through the mouth from the open end of the flexible extension tube.

[0009]

The artificial respirator having the above-mentioned structure can be expected to exhibit its function sufficiently in ordinary use. Is starting to be.

However, during use of this ventilator,
Alternatively, after resuscitation of the patient after use, the patient may exhale mochi, candy, etc., bleed, vomit, or cough, causing blood, sputum, or vomit to be splashed into the mouth of the practitioner. Sex cannot be denied.

In order to avoid such inconvenience, a ventilator has been proposed in which a filter is provided in the main body or a check valve is provided which allows only the air flow from the operator to the patient.

However, in the former case, the air flow (breath) from the practitioner is obstructed, so that the efficiency of the ventilator is reduced. In the latter case, the air flow from the practitioner is superimposed and the exhalation from the patient is reversed. It is dangerous because it is shut off by a stop valve

Accordingly, an object of the present invention is to solve the above-mentioned disadvantages and to provide an artificial respirator capable of blocking blood or the like from a patient.

[0014]

In order to achieve the above object, the invention according to claim 1 is characterized in that a flange-shaped mouth covering portion is provided at one end of a hollow main body tube and a guide nozzle inserted into a patient's mouth. And a flexible extension tube is detachably connected to the other end, wherein a filter body in which thin tubes extending in the length direction of the main body tube are bundled is provided in the main body tube. .

The invention according to claim 2 is characterized in that at least the filter body is made of an antibacterial synthetic resin.

Further, the invention according to claim 3 is that, at least in the above-mentioned filter body, an aqueous solution of (meth) acrylic acid and its ester-based copolymer, and an alcohol of (meth) acrylic acid and its ester-based copolymer are provided. An aqueous solution or an aqueous solution of an acrylic ester copolymer is applied.

A fourth aspect of the present invention is characterized in that a fine powder of calcium phosphate is adhered to at least the filter body using a water-soluble glucan as a binder.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a main body tube, which is provided with a flange-shaped mouth covering portion 2 and a guide nozzle 3 inserted into a patient's mouth at the lower end on the patient side, and has a flexible upper end. This is a thin cylindrical body to which the extension pipe 4 is detachably connected, and is usually made of synthetic resin.

The synthetic resin constituting the cylindrical body may be a so-called antibacterial one, since bacteria may be present in the breath of the patient. However, ordinary synthetic resins may be used.

[0020] Incidentally, antimicrobial synthetic resin, synthetic resin material, for example, _{XM 2n O · Al 2 O 3} · YSiO 2 · ZH 2 O
(However, M: ions of silver, sodium, etc., X, Y, Z:
Since the antimicrobial material represented by the structural formula (molar ratio of each component) is kneaded in and the antimicrobial synthetic resin itself is well known, further detailed description is omitted.

In the illustrated embodiment, a first filter body 5 to be described later is inserted into the inner cylinder, and as shown in FIG.
A lid cylinder 6 which is a stepped cylinder that covers the lower end opening of the main body cylinder 1 is integrally fitted to the main body cylinder 1 by welding or bonding.

Then, in the small-diameter cylindrical portion below the lid cylinder 6,
A mouth cover portion 2 having a connection hole not numbered at the center is fitted therein, and further, the mouth cover portion 2 is sandwiched between the cover cover 6 and a guide such as a rubber cylinder. The nozzle 3 is fitted on the small-diameter cylindrical portion.

In the illustrated embodiment, the lower end of the guide nozzle 3 is formed in a barrel shape so as to prevent the opening edge from being caught on the skin or the like when the guide nozzle is inserted into the mouth.

On the other hand, the flexible extension pipe 4 is a bellows-like pipe made of a synthetic resin such as a so-called petroleum pump pipe, and has a lower end connected coaxially to an upper end of the main body cylinder 1.
It is used by being detachably fitted to.

The outer peripheral surface of the connection tube 7 is
In order to strengthen the frictional engagement with the lower end portion, the cross section is formed in a sawtooth shape.

In the illustrated embodiment, the mouth cover 2 and the guide nozzle 3 are mounted on the upper end of the flexible connection pipe 4 in the same manner as the main body cylinder 1.

The upper end of the flexible connection tube 4 is for the practitioner to hold his / her mouth and blow his / her breath, and it is possible to blow his / her breath without the mouth cover 2 and the guide nozzle 3. These are not essential components of the present invention.

However, when the guide nozzle 3 is provided, the mouthfeel is smooth, and when the mouth cover 2 is provided, an elderly man whose teeth have come off can surely breathe.

The above configuration is the configuration of the ventilator previously proposed by the present applicant. The characteristic configuration of the present invention is as follows.
At least one (in the illustrated embodiment, two first and second filter bodies 5, 8) filter body is provided in the main body cylinder 1.

As shown in FIG. 3, for example, the first filter body 5 is formed by forming a large number of narrow tubes 9 having a hexagonal cross section along a length direction (general line direction) in a cylindrical shape in a honeycomb shape.

As shown in FIG. 4, the second filter 8 is formed by forming a large number of narrow tubes 9 having a rectangular or rectangular cross section along a longitudinal direction in a small-diameter cylinder with a flange. The cross-sectional shape of 9 is not limited to a hexagon or a rectangle, and may be, for example, a circle or an ellipse.

The first and second filter bodies 5 and 8 are:
For example, it is preferable to manufacture the resin by injection molding a synthetic resin material.
And the length thereof is desirably at least one time the diameter of the opening or the diameter of the circumcircle of the opening.

The material of the filter body is preferably an antibacterial synthetic resin, but may be an ordinary synthetic resin.

The first and second filter bodies 5 and 8 are connected to the main body cylinder 1.
In order to mount it inside, for example, the first and second filter materials 5,
8 is set slightly larger than the inner diameter of the main body tube 1 or the inner diameter of the connection tube 7, and the second filter material 8 is attached to the connection tube 7 before the lid tube 6 is attached to the main body tube 1. Then, the first filter material 5 is press-fitted into the main body tube 1 respectively.

As shown in FIG. 5, the respirator according to an embodiment of the present invention having the above-described configuration, for example, with the flexible extension tube 4 removed, first attaches the guide nozzle 3 to the tongue of the patient 11. And between the palate to secure the airway.

When the patient 11 is an adult, the patient 11
Insufflate the patient twice at intervals of 2 seconds, and then several times, once every 5 seconds.

After breathing in, the ear is brought close to the upper end of the main body cylinder 1 as shown in FIG.

Alternatively, as shown in FIG. 7, a flexible extension tube 4 is connected to the main body tube 1, and the patient 11 is breathed through the flexible extension tube 4 and the main body tube 1.

Then, in the same manner as shown in FIG. 6, the ear is approached to the upper end opening of the flexible extension tube 4 to examine whether or not the patient has exhaled.

Although not shown in FIGS. 5 and 6, the nose of the patient 11 is pinched like a clothespin so that the air blown into the patient 11 does not escape to the outside through the nasal cavity. It is good to pick at 13.

When the practitioner is breathing into the patient as described above, the breath passes through the filter body 5 (8) without resistance, so that artificial respiration should be performed as if the filter body did not exist. Can be.

By the way, during the treatment or after resuscitation, when the patient bleeds, vomits, or coughs, blood, sputum, or vomit enters into the main body cylinder 1 as droplets. If it is larger than the opening 9, it can be prevented from flying toward the practitioner by attaching it to the lower surface of the filter body on the patient side.

When the droplets of blood or the like are smaller than the opening of the thin tube 9, the droplets pass through the opening of the thin tube 9 and the filter body 5.
(8) Although the droplets enter, the droplets fly in a straight line in the main body cylinder, and there are almost no droplets having a velocity component parallel to the axis of the thin tube. It is absorbed by the filter body in a form of adhering to the filter body.

In rare cases, droplets that pass straight through the filter body 5 (8) usually adhere to the inner wall of the flexible extension tube 4 and cannot reach the operator.

When the filter body is made of an antibacterial synthetic resin, even if pathogenic bacteria enter the main body tube 1 for any reason, it can be sterilized.

The present invention is not limited to the illustrated embodiment, but can be implemented in various modifications.

For example, it is not necessary to form the thin tubes 9, 9 by perforating a solid cylinder as the filter body, and a thin tube 9 cut into a suitable length and bundled, for example, is used as the filter body. (Not shown).

At this time, an elongated gap formed between one thin tube and another thin tube adjacent thereto forms another thin tube.

Also, instead of forming the filter body from an antibacterial synthetic resin, an aqueous solution of (meth) acrylic acid and its ester copolymer, (meth) acrylic An aqueous alcohol solution of an acid and its ester-based copolymer or an aqueous solution of an acrylate-based copolymer may be applied.

These are used as antibacterial, antifungal and digestive odor agents, dry quickly after application, and are actually commercially available.

The coating agent is not limited to the filter body, but may be applied to the inside of the main body tube 1 or the connection tube 7 by, for example, a spray method.

Further, a solution in which calcium phosphate fine powder is mixed with, for example, water-soluble glucan is applied to a filter body or the like, and after drying, the calcium phosphate fine powder is adhered to the filter body or the like using the water-soluble glucan as a binder. You may.

In this case, since the fine powder of calcium phosphate has a property of adsorbing fungi and viruses in addition to ordinary dust, pathogenic bacteria and the like can be removed.

[0054]

As is apparent from the above description, according to the present invention, since the filter body in which a large number of thin tubes are bundled is provided in the main body cylinder, the function of blowing the breath into the patient, which is the original purpose, is lost. Without the patient's blood coughing,
An excellent effect of being able to adsorb and absorb droplets such as sputum and vomit in the filter body.
