Title
(EN) NO-LAG OXYGEN SUPPLY VENTILATOR SYSTEM
(FR) SYSTÈME DE VENTILATION D'ALIMENTATION EN OXYGÈNE SANS RETARD
(ZH) 无滞后供氧呼吸机系统
Abstract
(EN) A no-lag oxygen supply ventilator system, comprising a breathing mask (1), an air suction tube (2), an expiratory tube (3), an oxygen supply chamber (4), auxiliary oxygen supply tubing (23), and a start-stop cylinder (5) for opening and closing the auxiliary oxygen supply tubing (23). The breathing mask (1) and the oxygen supply chamber (4) individually communicate with the auxiliary oxygen supply tubing (23) by means of the air suction tube (2). The breathing mask (1) communicates with the outside by means of the expiratory tube (3). In the no-lag oxygen supply ventilator system, by providing the auxiliary oxygen supply tubing (23), a small amount of oxygen is supplied during the latter half of exhalation, compensating for the amount of oxygen required by a user in the induction inspiratory air flow lag time of the ventilator, avoiding the situation in which a user has difficulty breathing due to a lag in inspiratory oxygen supply, providing the user with an improved breathing experience. By means of the air flow of the expiratory tube (3), the starting and stopping of the auxiliary oxygen supply tubing (23) is controlled. Control is simple and convenient, exhalation is smoother, the temperature of the oxygen provided by the auxiliary oxygen supply tubing (23) is adjustable, and breathing is more comfortable.
(FR) L'invention concerne un système de ventilation d'alimentation en oxygène sans retard, comprenant un masque respiratoire (1), un tube d'aspiration d'air (2), un tube d'expiration (3), une chambre d'alimentation en oxygène (4), un tube d'alimentation en oxygène auxiliaire (23) et un piston d'arrêt/démarrage (5) servant à ouvrir et fermer le tube d'alimentation en oxygène auxiliaire (23). Le masque respiratoire (1) et la chambre d'alimentation en oxygène (4) communiquent individuellement avec le tube d'alimentation en oxygène auxiliaire (23) au moyen du tube d'aspiration d'air (2). Le masque respiratoire (1) communique avec l'extérieur au moyen du tube d'expiration (3). Dans le système de ventilation d'alimentation en oxygène sans retard, l'utilisation du tube d'alimentation en oxygène auxiliaire (23) permet de fournir une petite quantité d'oxygène pendant la seconde moitié de l'expiration, compensant la quantité d'oxygène requise par un utilisateur durant le temps de retard du flux d'air inspiratoire d'induction du ventilateur, évitant la situation dans laquelle un utilisateur a des difficultés de respirer en raison d'un retard dans l'alimentation en oxygène inspiratoire et offrant à l'utilisateur un ressenti de respiration amélioré. Le démarrage et l'arrêt du tube d'alimentation en oxygène auxiliaire (23) sont commandés au moyen du flux d'air du tube d'expiration (3). La commande est simple et commode, l'expiration est plus fluide, la température de l'oxygène fourni par le tube d'alimentation en oxygène auxiliaire (23) est réglable et la respiration est plus aisée.
(ZH) 一种无滞后供氧呼吸机系统,包括呼吸面罩(1)、吸气管(2)、呼气管(3)、供氧室(4)、辅助供氧管道(23)和用于开闭辅助供氧管道(23)的启停筒(5),呼吸面罩(1)和供氧室(4)之间分别通过吸气管(2)和辅助供氧管道(23)连通,呼吸面罩(1)通过呼气管(3)与外界连通,该无滞后供氧呼吸机系统通过设置辅助供氧管道(23),在呼气后半阶段就进行小量供氧,用于弥补呼吸机在感应吸气气流滞后时间内使用者所需的氧气量,避免使用者因吸气供氧的滞后而形成吸气吃力的情况,给予使用者更佳的呼吸体验,通过呼气管(3)的气流控制辅助供氧管道(23)的启停,控制简单方便,呼气更顺畅,辅助供氧管道(23)提供氧气的温度可调,呼吸也更舒适。
