Abstract

The object of the invention is the auxiliary device for the artificial breathing which is designed as the system of two chambers, A and B, both of equal volume, let's say, one-liter, and of similar form; besides: each chamber is made of a resilient material, for example, polyethylene or some other effortlessly inflating/ deflating material; each upper part of 3' and 3" is equipped with the air input/ output vent of 6' and 6" the thickened walls of which in comparison with the thickness of the material of the chamber provide the opportunity to insert in the aperture of 6' and 6" and tightly fix with the mediation of the transition element or the mouthpiece input end or the pipe 8, preferably frilled, one end of 8'; for the sake of the stability of the form the lower parts of both chambers of 2' and 2" as well as the upper parts of 3' and 3" are made as an integral formation of a slightly thickened material which is made of the base 2, the top 3 and the lateral walls 4' and 4" (or the lateral wall 4 as an integral formation), and the middle wall 5, preferably though not mandatory is common; coil springs of 1' and 1" are fitted into the interior of both chambers the ends of which (springs) are attached to the base 2 and the top 3.

Description

DESCRIPTION OF THE INVENTION

The invention relates to artificial lung ventilation devices which are manually operated and mainly used in emergency aids for cyclically providing fresh air to the lungs as well as exhausting the used air from the lungs. The device is used when the expiratory respiratory method is not applicable due to these or other circumstances (eg for medical or hygienic reasons), when the respirator actively exhales exhaled air from the victim's mouth (mouth) or nose (mouth), or at the same time through the mouth and nose. Apparatus and techniques for artificial respiration according to the international patent classification apply to subclass A61H31 / 00.

Apparatus for artificial respiration is known, which is used not only for breathing but also for administering anesthetics by inhalation. They are designed for long-term ventilation of the lungs and are designed so that the composition, humidity and temperature of the intake air, as well as the respiratory parameters (inspiratory rate, inspiratory volume, ventilation volume per minute, inhalation to exhalation ratio, etc.) can be changed as needed. This group includes the inventions described in patents / patent applications GB 2093218 (A), US 4945899 (A), JP 2131765 (A), CA 1294841 (C), RU 2174386 (C2), RU 2155021 (C1), RU 2236213 ( C2) RU 2246926 (C2), CN 101129291 (A). These inventions cannot serve as a prototype for the particular case.

A simple artificial respirator for applying pressure to the body / press body / to the sternum of a diseased or wounded person whose breath and pulse is stopped is described in patent application JP 10165503 (A). It is designed to perform cardiac massage while simultaneously injecting air into the larynx of the person being resuscitated by manually compressing / releasing the cylindrical chamber with an expansion / contraction spring mounted inside the bag between the lower and upper support surfaces, without any interval during the massage. The expansion / contraction chamber slides over vertical rod supports / guides during operation and is equipped with a grip for operating the expansion / contraction chamber by manually squeezing it and returning it to the uncompressed position by means of said spring, whereby air is injected / expelled into the larynx of the patient. . In addition, the chamber is equipped with air inlet and outlet valves so that the sick person's airway rhythmically injects / discharges air while performing cardiac massage and artificial respiration.

The mouthpiece / mouthpiece, outlet / mouthpiece for preventing direct contact between the rescuer and the victim suffering from asphyxia is described in patent application CA 1156121 (A1). This device has a tubular housing comprising an inlet portion and an outlet portion. The tubular housing has a central axial air passage that decreases / narrows / transition to the venturi area. At least one fresh air pot / duct, aisle / communicates with the Venturi area. The air passage in the outlet area narrows or has a constant cross-sectional area. This results in a Venturi effect (a change in the flow velocity caused by a drop in pressure in the flow zone with a variable cross-sectional area). When used, the device leads to mixing fresh ambient air with exhaled air delivered by the rescuer to the asphyxia victim, which results in an increase in the oxygen content of the air delivered to the victim during respiration. The protective shield is removably mounted on the tubular body so as to provide good sealing and prevent contact between the rescuer and the victim.

The auxiliary device described in this invention in two different positions a) and b) as well as tube 8 is shown in Fig. 1, where: Figs. 1a - its axial cross-section in the non-flattened position; FIG. 1b - its axial cross-section when flattened; FIG. 1c is a schematic view of a tube 8 with an 8 "tip inserted into the mouthpiece inlet.

FIG. In Fig. 1, the following designations are used: A and B - two identical cameras of flexible material; 1 ', 1 "- springs' 2 ', 2' - base A and B for chambers; 3 ', 3' 'camera

A and B uppers; 4 ', 4 ", 4 - side walls of chambers A and B; 5 - common partition wall of chambers A and B; 6 ', 6' - Conical apertures of chambers A and B; 8 - conduit for connecting auxiliary equipment to mouthpiece 9 or mask; 8 ', 8 "- 8-end tapered end elements of the tube, shaped to 6' and 6" shape of the tapered apertures, whereby the length of the 8-tube tube may in principle be very small, resulting in the 8 'and 8' elements being substantially uniform in the form of a transition element.

The auxiliary device shown in Fig. 1 is designed as a system of two single-volume, e.g., one-liter and uniform-shaped cameras A and B, each camera:

- made of a flexible material, eg polyethylene or other easy-to-inflate / blow-out material;

- each head 3 'and 3' is provided with an air inlet / outlet 6 'and 6', the thickened walls of which permit the insertion of a 6 'or 6' orifice into a stable member relative to the thickness of the chamber material, or either sucked in at the entrance end or with one end 8 'of the pipe 8, preferably corrugated;

- due to the shape stability, the lower 2 'and 2 "and the upper 3' and 3" of both chambers are formed as a one piece / integral / lightweight material consisting of base 2, top 3 and side walls 4 'and 4 " (or side wall 4 as one piece), but the middle wall 5 is preferably, but not necessarily, common;

- inside both chambers are mounted springs 1 'and 1', the ends of which are fixed to the base 2 and the top 3.

The shape of the cameras A and B can be arbitrary, preferably cylindrical. Each of them can be chosen in the form of a bag made of flexible material.

The artificial inhalation using the accessory shown in Fig. 1 takes place through the outlet 6 'and 6' in the process of artificial respiration alternately connected to the first end 8 'of the respiratory tube 8, the other end being either inserted into the mouth 9 or tightly covering the victim's mouth and nose. The following operations are performed sequentially during the respiratory process:

(a) one end 8 'of pipe 8 is connected to either mouthpiece 9 or mask;

(b) inserting the other end 8 'of the tube 8 into the opening 6' of the chamber A;

(c) both chambers A and B are manually compressed simultaneously, resulting in the air filled with chamber A being injected through tube 8 into the victim's mouth, larynx, airway, etc. and eventually entering the lungs, air from chamber B is expelled into the atmosphere and the device is moved from position a) to position b);

(d) when the external deforming force is removed, both chambers A and B return to position a) as a result of the action of the springs 1 'and 1', whereby in this transition the air from the injured lungs is withdrawn back into chamber A and chamber B is filled with fresh air from the environment;

(e) repeatedly performing operation (b), only this time inserting the tip 8 'of the tube 8 into the opening 6' of the chamber B;

(f) Repeat operation (c), only this time the function of the chamber A in the respiratory process is performed by the chamber B, i.e. the air filled with the chamber B, through the tube 8, etc. enters the lungs, but air from chamber A is expelled into the atmosphere and the device is moved from position a) again to position b);

(g) this operation is analogous to op d), only this time the air from the victim's lungs is drawn back into chamber B and chamber A is filled with fresh air from the surrounding environment;

(h) the operations from (b) to (g) are repeated as many times as necessary.

At the end of the breathing process, the 8 ends of the tube are disconnected from the mouthpiece or mask and accessories and all components are discarded as they are intended for single use only.

It is advisable to provide first aid kits with ambulatory equipment by adding a tube 8 and a mouthpiece 9 or a mask in a flattened position b) fixed, eg by clamps.
