发明内容
本发明的目的在于克服现有技术中的缺陷， 提供一种结构简单、 操作方便、 轻巧便携 的医用输液装置。
本发明的目的是通过以下方案来实现的： 一种医用输液装置， 包括输液泵、 液体容器、 茂菲氏滴管和流量调节器， 其中茂菲氏滴管与液体容器连接， 在该输液装置中设置有输液 加热器和报警器； 所述报警器中的探头、 加热器中的电热陶瓷管和流量调节器依次串接在 茂菲氏滴管上； 所述液体容器上设有药液出入口， 所述医用输液装置上还设置有压力调节 装置， 该压力调节装置上设有单向阀。
所述液体容器是由塑料或橡胶材料制成的软体输液袋， 所述压力调节装置是由塑料或 橡胶材料制成的气体袋或液体袋， 所述压力调节装置套装于液体容器外， 软体输液袋与所 述气体袋或液体袋之间设有一软材料隔膜。
所述液体容器是由硬性材料制成的输液瓶， 所述压力调节装置是由硬性材料制成的固 形块， 压力调节装置安装于液体容器一侧。
所述压力调节装置置于液体容器内部。
本发明的优点在于： 本发明的医用输液装置的液体容器和压力调节装置都不局限于具 体的软性材料或硬性材料， 也不局限于形状和大小， 可以从不同的角度和方位给液体容器 加压， 满足了快速输液或输血的需求， 本发明具有结构简单、 操作方便、 性能稳定、 轻巧 便携等优点。

实施例 2:
如图 1和图 3所示， 一种医用输液装置， 所述的医用输液装置包括输液泵、 茂菲氏滴 管 6、 液体容器 2和流量调节器 9， 其中茂菲氏滴管 6与液体容器 2连接， 在输液装置中设 置有输液加热器和报警器， 报警器中的探头 7、 加热器中的电热陶瓷管 8、 流量调节器 9依 次串接在茂菲氏滴管 6上； 在液体容器 2上设有药液出入口 1， 在所述医用输液装置上设 置有压力调节装置 3， 压力调节装置 3上设有单向阀 4; 液体容器 2是由塑料或橡胶材料制 成的软体输液袋或是由硬性材料制成的输液瓶； 压力调节装置 3是由塑料或橡胶材料制成 的气体袋或液体袋或是由硬性材料制成的固形块，压力调节装置 3安装于液体容器 2—侧。 本发明医用输液装置的压力调节装置 3从某个局部方向给液体容器 2施加压力， 使得液体 容器 2产生一定方向的压强， 迫使液体容器 2内的药液形成固定流向。 本医用输液装置的 工作过程为： 从药液出入口 1向液体容器 2内输入药液， 然后压力调节装置 3给液体容器 2局部压力， 从而使液体容器 2内的药液从药液出入口 1输出。
实施例 3:
如图 1和图 4所示， 一种医用输液装置， 所述的医用输液装置包括输液泵、 茂菲氏滴 管 6、 液体容器 2和流量调节器 9， 其中茂菲氏滴管 6与液体容器 2连接， 在输液装置中设 置有输液加热器和报警器， 报警器中的探头 7、 加热器中的电热陶瓷管 8、 流量调节器 9依 次串接在茂菲氏滴管 6上； 在液体容器 2上设有药液出入口 1， 在所述医用输液装置上设 置有压力调节装置 3， 压力调节装置 3上设有单向阀 4。
