Description

一种可调档位控制雾化量的便携式雾化器 技术领域
本发明涉及医疗器械领域，特别涉及一种可调档位控制雾化量的便携式雾化器。
背景技术
雾化吸入治疗是呼吸系统疾病治疗方法中一种重要和有效的治疗方法，采用雾化器将药液雾化成微小颗粒，使用者通过呼吸将药物吸入呼吸道和肺部沉积，经其粘膜吸收，从而达到无痛、迅速、有效治疗的目的。现有雾化器喷出的雾化量通常都是固定的，不能根据使用者的需求调节雾化量的大小，造成了很多弊端。譬如，若当雾气量过大时，患者不能充分吸收造成药液的浪费。另外，从喷雾口流出的药液也会刺激患者的眼睛等人体敏感器官，甚至会对周围环境造成一定的污染；当雾气量过少时，又起不到治疗效果。因此，现有的雾化器存在雾化量浪费和污染的缺陷。
发明内容
鉴于上述问题，本发明的目的在于提供一种可根据需求切换档位控制雾化器雾化量大小，以达到适量给药目的，及避免污染周围的可调档位控制雾化量的便携式雾化器。
为实现上述目的，本发明提供的一种可调档位控制雾化量的便携式雾化器，包括壳体、在壳体上设有的药液杯、在药液杯一侧的出口上设有的喷嘴和在喷嘴内设有的雾化片，及在壳体内设有与雾化片连接的电路板和在壳体内设有与电路板连接的电池。其中，所述的电路板包括主控单元，及在主控单元上设有分别连接的按键单元、升压单元和雾化片驱动单元。雾化片驱动单元与雾化片连接。主控单元包括主芯片，及在主芯片上设有的PWM输出引脚、采样信号输入引脚和控制信号输入引脚。雾化驱动单元上设置有与PWM输出引脚连接的场效应管端。雾化驱动单元上设置有与采样信号输入引脚连接的场效应管反馈端。控制信号输入引脚与按键单元连 接。主控单元通过调节PWM输出引脚的输出功率控制雾化量的大小。
在一些实施方式中，按键单元包括在壳体上设有与电路板连接的电源按键、加号按键和减号按键。壳体的背面上设置有用于电池充电的Micro USB接口。
在一些实施方式中，雾化片设置于喷嘴的中心位置且与药液箱底部的出口相连通。
在一些实施方式中，药液箱与喷嘴一体成型。
在一些实施方式中，药液箱上方设置有用于打开和闭合药液箱的上盖。
在一些实施方式中，电池为钛酸锂可充电电池。
本发明的有益效果具体如下：在雾化器启动时，升压单元输出固定的驱动电压，主控单元输出不同的驱动频率控制雾化片驱动单元以驱动雾化片，同时在输出每一个频率时检测雾化片的反馈电压并记录。通过以上雾化片驱动单元对雾化扫频方式，可以得到一个雾化片的最佳谐振频率及其对应加载在雾化片驱动单元上的驱动频率。锁定该驱动频率不变，当主控单元检测到不同档位对应的控制信号输入时，通过调节PWM输出功率从而调节平均工作电压以达到控制雾化量的目的，如此，可实现根据需求切换档位控制雾化器雾化量大小，以达到适量给药目的，及避免污染周围的效果。

图5为PWM输出功率30％的波形示意图。
具体实施方式
下面结合附图对发明作进一步详细的说明。
如图1-3所示，一种可调档位控制雾化量的便携式雾化器，包括壳体1、在壳体1上设有的药液杯2、在药液杯2一侧的出口上设有的喷嘴3和在喷嘴3内设有的雾化片4，及在壳体1内设有与雾化片4连接的电路板5和在壳体1内设有与电路板5连接的电池6。所述的电路板5包括主控单元，及在主控单元上设有分别连接的按键单元、升压单元和雾化片驱动单元。雾化片驱动单元与雾化片4连接。主控单元包括主芯片，及在主芯片上设有的PWM输出引脚、采样信号输入引脚和控制信号输入引脚。雾化驱动单元上设置有与PWM输出引脚连接的场效应管端；所述的雾化驱动单元上设置有与采样信号输入引脚连接的场效应管反馈端；所述的控制信号输入引脚与按键单元连接。主控单元通过调节PWM输出引脚的输出功率控制雾化量的大小。按键单元包括在壳体1上设有与电路板5连接的电源按键、加号按键和减号按键。壳体1的背面上设置有用于电池6充电的Micro USB接口。雾化片4设置于喷嘴3的中心位置且与药液箱底部的出口相连通。药液箱与喷嘴3一体成型。在药液箱4侧面设置有卡槽，壳体1上设置的滑块、复位弹簧等结构，用于将壳体11和药液箱4可拆卸连接。作为上述变形结构，壳体1和药液箱4也可采用螺纹、铰接、滑轨等其它可拆卸方式连接。药液箱上方设置有用于打开和闭合药液箱的上盖。电池6为钛酸锂可充电电池6。上述主控单元用于整个电路部分的逻辑控制部分，负责输出驱动频率并记录信息。升压单元用于输出加载在雾化片驱动单元两端的电压。雾化片驱动单元用于根据驱动频率和驱动电压以驱动雾化片4。按键单元用于交互输入信号以启动主控单元烧录的程序。
在雾化器启动时，升压单元输出固定的驱动电压，主控单元输出不同的驱动频率控制雾化片驱动单元以驱动雾化片4，同时在输出每一个频率时检测雾化片4的反馈电压并记录。通过以上雾化片驱动单元对雾化扫频方式，可以得到一个雾化片4的最佳谐振频率及其对应加载在雾化片驱动单元上的驱动频率。锁定该驱动频率不变，当主控单元检测到不同档位对应的控制信号输入时，通过调节PWM输出功率从而调节平均工作电压以达到控制雾化量的目的，如此，可实现根据需求切换档位控制雾化器雾化量大小，以达到适量给药目的，及避免污染周围的效果。
如图3-5所示，在场效应管Q1的驱动端和反馈端还分别连接有分压电阻R6、R7和R8。按键单元包括与主控单元信号输入端上第五引脚相连的按键开关KEY1、与第六引脚相连的按键开关KEY2和与第七引脚相连的按键开关KEY3,其可根据主控单元引脚对应烧录的程序分别执行电源启动\关闭、雾化速率增大、雾化速率减少功能。各元器件及其连接方式仅是该实施方式中的一种，增加其他功能电路例如滤波电路、稳压电路等也应属于本发明的变形方式。
电路板5的工作原理，主控单元接收按键开关KEY1交互输入信号后开始扫频。升压单元在A处输出固定的驱动电压，主控单元输出由低到高的驱动频率以调节B处的频率，雾化片4开始振动；同时主控制器在输出每一个频率时检测C处的反馈电压并记录信息；这一过程为雾化片4的扫频阶段。该记录信息可以包含雾化片4的谐振频率、其所对应的雾化量大小、反馈电压、所加载的驱动频率等信息。然后选定最大雾化量对应的谐振频率为最佳谐振频率，主控单元输出该最佳谐振频率所对应的驱动频率并锁定不变。开始雾化时，雾化器以一个适中的雾化量雾化，当主控单元接收按键开关KEY2、KEY3交互输入信号后，通过调节PWM输出功率来调节平均工作电压，最终达到控制雾化量大小的目的。例如驱动频率为130KHz的雾化器按下KEY1启动时主控单元以图4所示的PWM波形图开始输出，其所产生的平均工作电压及其对应雾化量为50％。当主控单元检测到KEY2按下后雾化量减少，PWM频率输出功率变为如图5所示，其平均工作电压及其对应雾化量为30％。
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于发明的保护范围。
