Abstract
The equipment disposes of the gases exhaled by the patient, and comprises a closed vessel (A) with an inlet for the exhaled gases (P) and an outlet for them at the bottom (H). The inlet pipe has an adjustable valve (F, G) inside the vessel. There can be a venturi in the outlet. The equipment protects the operating theatre staff against intoxication and other harmful effects resulting from gases such as fluothane and penthrane. An adjusting screw (E) at the top of the closed vessel (A) is used to control the degree of opening of the valve (F, G).
Description
La présente invention a pour objet un dispositif pour l'élimination des gaz exhalés par un patient sous anesthésie.
Les techniques actuelles de l'anesthésie opèrent avec des équipements qui n'éliminent pas l'air et les gaz exhalés par le patient à l'extérieur du local, ce qui a pour effet d'exposer le personnel travaillant en salle d'opération à des risques d'intoxication dus à des gaz tels que le Fluothane qui engendre des hepato- toxiques et le Penthrane qui engendre des disfonctions rénales. En effet, il est reconnu dangereux d'utiliser ces gaz pour les patients plus d'une fois par mois, alors que le personnel travaillant en salle d'opération, et particulièrement l'anesthésiste, y sont exposés journellement.
L'invention a pour but d'éviter ces inconvénients. Le dispositif qui en fait l'objet est caractérisé en ce qu'il comprend un récipient fermé muni d'une conduite d'entrée pour les gaz exhalés par le patient et d'une conduite de sortie placée à la partie inférieure du récipient pour l'évacuation de ces gaz, la conduite d'entrée étant munie, à l'intérieur du récipient, d'une valve réglable.
La figure unique du dessin ci-joint représente, à titre d'exemple et schématiquement, une forme d'exécution de la présente invention.
Le dispositif représenté comprend un récipient fermé en matière transparente A, pourvu de deux fonds B et C, et d'une conduite d'entrée P, disposée sur le circuit expiratoire L du patient, les dimensions du récipient étant appropriées au volume expiratoire d'un être humain. Une valve F G, disposée à l'extrè- mité de la conduite P, est pourvue, à son sommet. d'une vis de réglage E, permettant de varier la pression intrapulmonaire selon le besoin du patient, la valve F G, avec son siège G, présentant une forme étudiée pour faciliter l'écoulement descendant des gaz exhalés.
Les gaz introduits dans le récipient A, soit par l'expiration spontanée du patient, soit avec l'assistance de l'anesthésiste.
s'écoulent librement par la conduite de sortie H. située à la partie inférieure du récipient, et sont ensuite évacués soit par un manchon perforé, soit par un venturi I, dont une extrémité est branchée sur l'aspiration J, qui extrait les gaz à l'extérieur.
The present invention relates to a device for the elimination of gases exhaled by a patient under anesthesia.
Current anesthesia techniques operate with equipment that does not eliminate the air and gases exhaled by the patient outside the room, which has the effect of exposing personnel working in the operating room to risks of poisoning due to gases such as Fluothane which generates hepato-toxins and Penthrane which causes renal dysfunction. In fact, it is recognized as dangerous to use these gases for patients more than once a month, while the personnel working in the operating room, and particularly the anesthetist, are exposed to them daily.
The object of the invention is to avoid these drawbacks. The device which is the subject thereof is characterized in that it comprises a closed container provided with an inlet pipe for the gases exhaled by the patient and an outlet pipe placed at the lower part of the container for the 'evacuation of these gases, the inlet pipe being provided, inside the container, with an adjustable valve.
The single figure of the accompanying drawing represents, by way of example and schematically, an embodiment of the present invention.
The device shown comprises a closed container made of transparent material A, provided with two bottoms B and C, and an inlet pipe P, arranged on the patient's expiratory circuit L, the dimensions of the receptacle being appropriate to the expiratory volume of a human. A valve F G, arranged at the end of the pipe P, is provided at its top. an adjustment screw E, making it possible to vary the intrapulmonary pressure according to the patient's needs, the valve F G, with its seat G, having a shape designed to facilitate the downward flow of the exhaled gases.
The gases introduced into container A, either by the patient's spontaneous expiration or with the assistance of the anesthetist.
flow freely through the outlet pipe H. located at the lower part of the container, and are then discharged either through a perforated sleeve, or through a venturi I, one end of which is connected to the suction J, which extracts the gases outside.
