Abstract

一种滤出药粉吸入器。因药粉微粒吸力强、易聚团难分离；每次药量少、难分装，故干粉中掺入占总量最多达98.8％的乳糖，但长期吸入乳糖有副作用；然而为少吸乳糖，采取少吸干粉，结果溅少了吸药量，所以疗效差。本发明特点是：从干粉中分离出药粉，快速吸入足量，疗效显著。主要用于防治哮喘等多种疾病。

Description

滤出药粉吸入器
技术领域
本发明涉及一种医疗器械，尤其是一种滤出药粉吸入器，具体地说是单独使用，或与药粉吸嘴等配套组成新的吸入器。 
背景技术
现有多种干粉吸入器吸入治疗哮喘，符合GINA的治愈率仅约5％。由于吸入用药粉微粒易聚集、难分离；每次药量少难分装，故掺入乳糖占干粉总量最多达98.8％，但长期吸入乳糖有副作用。而为少吸乳糖减少吸入干粉，结果也溅少了药粉量，所以疗效差。 
发明内容
本发明的目的在于：从干粉中分离出药粉，快速吸入量足，去除乳糖，疗效显著。 
本发明目的是这样实现的：一种滤出药粉吸入器，包括底座(1)、上座(2)；底座(1)中设有胶囊室(4)，室下侧(81)处呈半月形朝上凹槽，室两端各设有三角形刺刀(6)，分别配有按钮(5)、按钮(5a)和回位弹簧；上座(2)通过一侧洞孔(64)内的轴活动安装于底座(1)上，通过另一侧定位挂钩(2a)与底座(1)合拢或开启；上座(2)中的通道(18)口处有栅栏(66)，其特征在于： 
a)所述的上座(2)中设有隔板(62)，其下端连着压槽(63)，槽下面(82)处呈半月形朝下凹槽； 
b)所述的上座(2)上设有与吸管(131)匹配的中空管外侧连接处(10)，中空管(19a)经通道(18)与隔板(62)一侧空腔(9)相通；或中空管(19a)延长约8厘米成吸嘴； 
c)所述的上座(2)内的空腔(9)中可设有过滤用件(121)； 
在本发明中：底座(1)的外面设有底座罩(72)，其立面有方格框(73)，罩在按钮(5a)上，减少空气进入空腔(9)内，使吸药通道相对封闭，快速吸出药粉。 
在本发明中：包括吸管(131)与吸管(132)相连接在内的多个吸管依次连接成吸嘴，或吸管(131)上连接至少两个小吸管(131a)组成吸嘴；或在吸管内有包括过滤杯在内的过滤用件(121)，其过滤孔数量、形状、大小、层次根据需要设定，过滤孔拦住6微米以上大小微粒。 
在本发明中：中空管(19a)内有插管(67)、球体(68)和栅栏。 
在本发明中：上座(2)上配有吸嘴罩(71)，将包括吸管(131)罩于其中，或在吸嘴罩(71)上设有药品存放室(74)。 
本发明的优点在于：底座罩(72)使吸药通道相对封闭，吸药时气流经过胶囊内将干粉迅速带出，并滤出药粉，第一时间吸入足量，疗效显著。

具体实施方式
下面结合附图对本发明作进一步说明。 
实施例1： 
滤出药粉吸入器(见图6)由底座(1)、上座(2)等组成。上座(2)的中空管延长约8厘米为吸嘴，管腔(19a)为药粉吸出口；上座(2)内的空腔(9)中有过滤袋(121)。使用时，先取下底座罩(72)，按一下挂钩(2a)开启上座(2)，将胶囊(8)放入胶囊室(4)中，然后将上座(2)重新合拢在底座(1)上。接着，用两手指同时按下两个按钮(5、5a)，刺破胶囊后，再将底座罩(72)从按钮(5a)这一侧推进。在药粉吸出(19a)吸药时，空气从进气口(7a)流入空腔(7)→经刺破口(8a)到胶囊(8)内，气流带着干粉从刺破口(8b)→到空腔(9)的过滤袋内，例如10微米以上大小乳糖微粒被阻挡在过滤袋内，5微米以下大小的药粉微粒被快速吸入呼吸道。使用后拆洗吸入器，吹干后备用。 
上座(2)中的隔板(62)和压槽(63)的作用：1、将上座(2)中的空腔分为空腔(7)与(9)，使气流主要从胶囊内带着干粉到空腔(9)内；2、压住胶囊，将胶囊内空气挤向两端，利于刺破；3、用手抓过的胶囊，其表面污染处被上、下凹槽压着，避免接触气流与干粉，预防交叉感染。 
实施例2： 
一种滤出药粉吸入器(见图8)，在吸嘴管腔中有过滤袋(121)。腔道(19a)中可放置 插管(67)和球体(68)，然后将吸管(131)与中空管(10)连接。吸气时，干粉受到球体(68)的震动，撞击乳糖微粒分离药粉微粒，利于过滤。如果无意中向药粉吸入器内呼气，球体(68)堵在插管狭部，避免药粉被呼出器具。 
本发明具体实施时，注塑制作，也可用金属、新材料等制成。分别制成各组件，匹配连接。
