The utility model discloses an inhalation aerosol dosing adapter in a ventilator loop, which comprises an adapter body and a propellant cover. Its characteristics are as follows: the adapter body is a stepped cylindrical shape, including a dispensing tube and a mist storage chamber, the inner part of the dispensing tube is a dispensing chamber, one end is an open opening, and the outer wall of the dispensing tube has a T-shaped sliding groove along the axis, and the number of sliding grooves. The pushing charge cover consists of a cover body and a connecting rod. The connecting rod is connected on both sides of the cover body. The end of the connecting rod is connected with a movable slider. The slider is located in the sliding groove. The mist storage chamber and the dispensing chamber are connected through a step hole, and one end of the mist storage chamber is connected with an extension tube. The utility model can implement aerosol inhalation drug treatment for patients when they use mechanical ventilation with respirator, without leaving the respirator, and can avoid the concentration reduction of aerosol when it enters the inhalation duct, so that the drug can not reach the respiratory tract of patients.
【技术实现步骤摘要】
一种呼吸机环路内吸入气雾剂加药适配器
本技术属于医疗器械领域,涉及一种在面罩机械通气、气管机械通气情况下将气雾剂输送到气管、支气管的加药适配器。
技术介绍
使用气雾剂吸入治疗是治疗哮喘、慢性喘息性支气管炎、慢性支气管炎急性发作期等疾病的有效方法之一,尤其在急性期缓解症状有重要作用。当患者哮喘发作、慢性支气管炎急性期,病人缺氧,氧需增加,患者呼吸频率快、潮气量小,气雾吸入治疗时,气雾剂很难吸入到下呼吸道起作用,尤其在患者需要面罩或气管插管呼吸机通气时,很难使用气雾剂吸入治疗,由于病人潮气量小,气雾很难到达呼吸道,且气雾进入呼吸机吸气管时,气雾发生扩散,浓度降低,更难到达患者肺部和呼吸道。
技术实现思路
为了解决上述问题,本技术设计了一种呼吸机环路内吸入气雾剂加药适配器,本技术可以在患者使用呼吸罩机械通气时,在不脱离呼吸罩的情况下,就可以对患者实施气雾吸入药物治疗,并且可以避免气雾在进入吸气导管时浓度降低,致使药物无法到达患者呼吸道内。为了达到上述技术目的,实现上述技术效果,本技术是通过以下技术方案实现的:一种呼吸机环路内吸入气雾剂加药适配器,包括适配器主体和推药盖,其特征在 ...
