Abstract

The invention concerns a protective device for life- saving by the mouth-to-mouth method, with features which protect against infection. The easy-to-carry device according to the invention makes it possible to give respiratory assistance irrespective of the situation and circumstances. By covering the nose and mouth, it is possible for anyone to provide respiratory assistance without touching or putting one's fingers into the mouth, for example to change the position of the tongue, and without any fear of infection or the like. The invention allows a free flow of air as a result of the check valve construction and has no built-in resistance to respiratory assistance. <IMAGE>

Description

462 280 4 Figur 2 Här visas att, vid andningshjälp, ingenting hindrar inblàsningsluft_2, vid hjälptillfället, utan obe- hindrat passerar kulan_Z i backventilen g vilken dà vilar ovanpä nätfällan_§. Backventilen_§ kan utföras i annat material och i annan konstruktion till lägre kostnad, för engàngsbruk, t ex ersätta backventilen_§ med enkel membranventil eller med en fjäderbelastad kägla, dessa konstruktioner ger dock ett större and- ningsmotstànd och blir ej lika kontrollerbart som back- ventilen Q med kula 1. 462 280 4 Figure 2 Here it is shown that, when breathing, nothing obstructs the supply air_2, at the time of help, but the ball_Z passes unhindered in the non-return valve g which then rests on top of the net trap_§. The non-return valve_§ can be made of another material and in another construction at a lower cost, for single use, eg replace the non-return valve_§ with a simple diaphragm valve or with a spring-loaded cone, these constructions provide greater breathing resistance and are not as controllable as the non-return valve Q with ball 1.

Förklarar detta med att kulan_Z vilar pà nätet § och att reaktionen fràn den nödlidande kan kontrolleras i denna backventilskontruktion_§ eftersom inget andnings- hinder föreligger, emedan det i andra konstruktioner finns inbyggd belastning via fjäderbelastad kägla eller ett fast membran, detta kan göra att andnings- masken-skyddsanordningen, värsta fall, om den kvarhàlles över ansiktet kan förvärra situationen för den nödlidande.Explains this with the fact that the ball_Z rests on the net § and that the reaction from the distressed can be controlled in this non-return valve construction_§ because there is no obstruction to breathing, since in other constructions there is a built-in load via spring-loaded cone or a fixed diaphragm, this can cause the mask protection device, worst case, if kept over the face can aggravate the situation of the distressed.

Figur 3 Här visas vid reaktion-utandning, hostning eller liknande från den nödlidande, hur kulan Z anpassas mot utformat tätningssäte och oförhindrat kan falla ned pà nätet §, genom att kulan_Z, t ex kokningsbar-av làg vikt, tätar mot utformat säte, förhindras den hjälpande att fà nagon form av substans i ansiktet.Figure 3 Here, in the case of reaction-exhalation, coughing or the like from the distressed person, it is shown how the ball Z is adapted to the designed sealing seat and can fall unobstructed on the net §, by preventing the ball_Z, eg low boiling point, from sealing against the designed seat. the helping to get some kind of substance in the face.

Figur U Här visas backventilen g underifrån med nät §, kulan_Z samt ett exempel pä stoppklackar_§.Figure U The non-return valve g is shown from below with net §, ball_Z and an example of stop lugs_§.

Munstycket l_kan ersättas med rakt rörmunstycke, vinklat rörmunstycke eller ledat- och förlängt rörmustycke, det senare för att, om så är fallet, ej behöva flytta den nöd- lidande av någon orsak vid rådande omständighet.The nozzle l_can be replaced with a straight pipe nozzle, angled pipe nozzle or articulated and extended pipe nozzle, the latter so that, if this is the case, the need does not have to be moved for any reason in the prevailing circumstance.

Life-saving breathing mask intended for use between a rescuer and a patient and adapted to cover the nose and mouth of the patient, characterized in that the mask (4) is provided with a non-return valve (2) with a ball (7) of the free-blowing type, i.e. the valve does not normally provide respiratory resistance in any direction, but during rapid exhalation, eg coughing from the patient, seals the ball (7) against a valve seat (6) and thereby protects the rescuer from infection.

Breathing mask according to Claim 1, characterized in that the ball (7) rests against a number of lugs (5).

Breathing mask according to Claim 1, characterized in that the ball (7) rests against a night (8).

Breathing mask according to Claim 1, characterized in that the mask (H) is shaped to the face and covering the nose and mouth.
