Abstract

A general anesthesia rebreathing system comprised of a disposable portion easily coupled to and decoupled from a permanent portion. The disposable portion includes conventional breathing tubing for coupling a source of fresh gas, as from an anesthesia machine, to a patient and in addition an overflow tube for coupling the patient end of the system to an overflow (pop-off) valve, preferably mounted on the machine and constituting part of the permanent portion. The overflow tube entrance is located close to the patient end of the system and in communication with the tubing which conveys expired gas to a reservoir, such as a conventional breathing bag, mounted at the machine end. The arrangement assures that the patient's initially expired dead space gas is conveyed by the tubing to the reservoir with subsequently expired alveolar gas being exhausted through the overflow tube and pop-off valve.

Изобретение относитс  к медицинской технике.The invention relates to medical technology.

Известен аппарат дл  наркоза, содержащий основную и съемную часть, включающую трубопроводы вдоха и выдоха , соединённые с дыхательным мешком и дыхательной маской, блок соединени  трубопроводов с органами дыхани  пациента и клапаны вдоха и выдоха однонаправленногбдействи , -а так же блок производства дыхательной смеси 1 .The anesthesia apparatus is known, which contains a main and removable part, which includes inspiration and expiratory conduits connected to the breathing bag and breathing mask, a unit connecting the pipelines to the patient's respiratory organs, and unidirectional exhalation and exhalation valves, as well as a breathing mixture production unit 1.

Однако в этом аппарате сьемна  часть, предназначенна  .дл  стерилизации , имеет сложную конструкцию, что затрудн ет подготовку аппарата к работе при смене пациентов.However, in this apparatus, the removable part, intended for sterilization, has a complex structure, which makes it difficult to prepare the apparatus for operation when changing patients.

При этом сьемна  часть не может быть предназначена дл  одноразового использовани  с целью обеспечени  быстрого перехода от одного пациента к другому, так как в этом случае значительно удорожаетс  стоимость аппарата. Кроме того, в этом аппарате не обеспечена полна  изол ци  основной его части, не подвергающейс  стерилизации, от системы вентил ции пациента, что приводит к инфицированию аппарата и возможности пе ррлачи  пфркции другим пациентам.In this case, the removable part cannot be designed for one-time use in order to ensure a rapid transition from one patient to another, since in this case the cost of the apparatus increases significantly. In addition, this device does not provide complete isolation of the main part, which is not subjected to sterilization, from the patient's ventilation system, which leads to infection of the device and the possibility of transferring the function to other patients.

Цель изобретен.и  - обеспечение быстрой подготовки аппарата к работе при смене пациентов и полной изол ции дыхательного аппарата от систег.1ь венб тил ции пациента.The purpose of the invention was to provide rapid preparation of the device for work when changing patients and completely isolating the breathing apparatus from the system of ventilating the patient.

Поставленна  цель достигаетс  тем, что аппарат содержит монтажный блок, состо щий из корпуса с фиксаторами и трубками дл  подсоединени  трубопроводов, дыхательного мешка и клапанов .выд н.This goal is achieved by the fact that the apparatus contains a mounting block consisting of a body with clamps and tubes for connecting pipelines, a breathing bag and valves.

Аппарат содержит основную и сьемную части, трубопровод 1 вдоха, 25 трубопроводы 2,3 выдоха, соединенные с дыхательным мешком 4 и дыхательной маской 5. Сьемна  часть включает блок 6 соединени  трубопроводов с органами дыхани , несущий клапан 7 выдоха , однонаправленного действи  и предохр.анительный клапан (на чертеже не показан ) . К блоку 6 подсоединена дыхателна  маска 5. Основна  часть аппарата включает блок 8 производства дыхательной смеси с кронштейном 9, на котором размещена плата 10 с манометром 11, перепускным клапаном 12 и распределительным клапаном 13. Плата 10 снабжена патрубком 14 дл  соединени  с блоком 8 и шпильками 15 дл  механического соединени  с монтажным блоком 16, Монтажный блок 16 состоит из корпуса 17 с фиксаторами 18, которые взаимодействуют со шпильками 15 и кольцевыми проточками 19, выполнеными на концах шпилек, В корпусе 17 1 юнтажного блока выполнены канавки 20 в качестве посадочных мест дл  шпилек 15 и установлены: трубка 21 дл  подсоединени  дыхательного мешка 4,- трубка 22 дл  подсоединени  клапана 23 вдоха однонаправленного действи . Кроме того, в корпусе 17 установлены патрубки 24-27 дл  подсоединени  соответственно, трубопров да 2 выдоха, канала 28 платы 10, второго трубопровода 3 выдоха и канала 29 платы 10. Канал 28 предназначен дл  подачи дыхательной смеси от блока 8 и его пропускна  способность установлена такой величины, что исключена возможность проникновени  выдыхаемого газа в основную часть аппарата. Канал 29 предназначен дл  подачи выдыхаемого газа к перепускному и распределительному клапанам.The device contains main and removable parts, inspiration pipe 1, 25 expiratory pipes 2.3, connected to breathing bag 4 and breathing mask 5. The removable part includes a pipeline connecting unit 6 with respiratory organs, an exhalation carrying valve 7, unidirectional and protective valve (not shown). A respiratory mask 5 is connected to block 6. The main part of the device includes a breathing mix unit 8 with a bracket 9, on which is placed a plate 10 with a pressure gauge 11, a relief valve 12 and a control valve 13. The plate 10 is equipped with a socket 14 for connection with block 8 and pins 15 for mechanical connection with the mounting block 16, the mounting block 16 consists of a body 17 with clamps 18, which interact with studs 15 and annular grooves 19, made at the ends of the studs. ki 20 as seats for the pins 15 and set: a tube 21 for connecting the breathing bag 4 - inspiratory tube 22 for the valve 23 connecting the unidirectional effect. In addition, in the housing 17 are installed nozzles 24-27 for connecting, respectively, the exhalation pipe 2, the channel 28 of the board 10, the second pipe 3 of the exhalation and the channel 29 of the card 10. The channel 28 is designed to supply the breathing gas from block 8 and its capacity is set of such a size that the possibility of penetration of the exhaled gas into the main part of the apparatus is excluded. Channel 29 is designed to supply exhaled gas to the bypass and distribution valves.

Причем патрубок -14 платы 10 соедин етс  с блоком 8 производства дихательной смеси трубопроводом 30, а каналы 28 и 29 снабжены уплотнител ми 31 и 32 .Moreover, the nozzle -14 of the board 10 is connected to the breathing mixture production unit 8 by a conduit 30, and the channels 28 and 29 are provided with seals 31 and 32.

Аппарат используетс  следующим образом.The apparatus is used as follows.

Конструкци  аппарата выполнена .аким образом, что его основна  часть не требует стерилизации после окончани  работы, так как она остаетс  изолированной от систеьсл вентил ции пациента. Эта изол ци  достигаетс  прежде всего тем, что выдыхаемы газ не проникает в основную частьThe apparatus is designed. In such a way that its main part does not require sterilization after completion of the work, since it remains isolated from the patient's ventilation system. This isolation is achieved primarily by the fact that the exhaled gas does not penetrate into the main part
