Description

防浮肿输液器
技术领域
本发明涉及医疗器械领域，特别地，涉及一种输液器。
背景技术
输液器是一种基础医疗器械，主要包括输液针、输液管，以及串接于输液管上的流速调节器、滴管；在输液过程中，如输液针的注射位置不佳，或由于患者手臂的不当移动，将导致输液器的药液输出受阻，使药液较难畅通地流入血管；在此情况下，输液针附近的皮肉组织将发生肿胀现象；然而，由于输液针通常被胶带、衣物等遮盖，且在输液过程中，由于皮肉组织受到输液针、胶带的影响，严重程度较低的浮肿现象，通常较难感知；这导致在输液过程中，患者的局部皮肉可能长时间处于肿胀状态，这对于将对皮肉组织带来一定的危害，并且影响输液质量。
发明内容
针对上述问题，本发明的目的在于提供一种防浮肿输液器，该输液器可以方便地查看是否输液阻力过大，从而判断皮肉组织是否具有浮肿倾向，以便于及时发现和调整输液针的不当位置状态。
本发明解决其技术问题所采用的技术方案是：该防浮肿输液器包括输液针、输液管；所述输液管中串接有滴管，且输液管上设有调速器；所述输液针与输液管之间还串接有监测器；所述监测器包括一个圆形腔体，所述圆形腔体的底面及侧面为硬质面，正面则由弹性膜构成，所述弹性膜的弹性系数小于人体皮肉组织；所述输液管内的药液横向流经所述圆形腔体后流至所述输液针。
作为优选，所述圆形腔体包括一个开口朝上的圆盖状的硬质底盒，以及一个设于该硬质底盒内的，由弹性膜构成的圆形囊，所述圆形囊的底面、侧面与所述硬质底盒的底面、侧面完全贴合，所述输液管内的药液横向流经所述圆形囊；从而避免了圆形腔体的正面因向上膨胀而导致脱离或渗漏的问题。
作为优选，所述圆形腔体正面的弹性膜为透明膜，所述圆形腔体的内底面上制有一道色环；所述圆形腔体上方还覆盖一个透明罩盖，该透明罩盖与所述弹性膜之间具有间隔，且所述透明罩盖上制有径向延伸的刻度线。
本发明的有益效果在于：该防浮肿输液器在输液过程中，如输液针的输液阻力较小，药液畅通地流入血管，则所述调速器至输液针之间的液体压力较小，所述圆形腔体正面的弹性膜基本不发生膨胀；而当输液针的位置状态不佳，导致输液阻力明显增大时，药液在输液针附近积压，导致所述圆形腔体内的液体压力明显增大，且由于所述弹性膜的弹性系数小于皮肉组织，故在皮肉组织浮肿之前，所述弹性膜首先向上膨胀凸起，由此，通过观察所述监测器正面的弹性膜的状态，即可判断皮肉组织是否具有浮肿倾向，以便于及时发现和调整输液针的不当位置状态。
附图说明
图1是本防浮肿输液器一个实施例的示意图。
图2是本防浮肿输液器中，监测器的实施例一的状态变化示意图。
图3是本防浮肿输液器中，监测器的实施例二的侧向示意图。
图4是本防浮肿输液器中，监测器的实施例二的状态变化示意图。
具体实施方式
下面结合附图和实施例对本发明进一步说明：
如图1所示，本防浮肿输液器包括输液针1、输液管2；所述输液管2中串接有滴管3，且输液管2上设有调速器4；所述输液针1与输液管2之间还串接有监测器5。
所述监测器5的实施例一如图2所示，其包括一个圆形腔体50，所述圆形腔体50，该圆形腔体50包括一个开口朝上的圆盖状的硬质底盒51，以及一个设于该硬质底盒51内的，由弹性膜构成的圆形囊52，所述圆形囊52的底面、侧面与所述硬质底盒51的底面、侧面完全贴合，所述输液管2内的药液横向流经所述圆形囊52；所述弹性膜的弹性系数小于人体皮肉组织，即较之于皮肉组织，所述弹性膜更易于膨胀。
所述输液管2内的药液横向流经所述圆形腔体50后流至所述输液针1。
上述防浮肿输液器在输液过程中，如输液针1的输液阻力较小，药液畅通地流入血管，则所述调速器4至输液针1之间的液体压力较小，所述圆形腔体50正面的弹性膜基本不发生膨胀，如图2中左半部分所示；而当输液针1的位置状态不佳，导致输液阻力明显增大时，药液在输液针1附近积压，导致所述圆形腔体50内的液体压力明显增大，且由于所述弹性膜的弹性系数小于皮肉组织，故在皮肉组织浮肿之前，所述弹性膜首先向上膨胀凸起，如图2中右半部分所示；由此，由于监测器5是不受胶布或衣物覆盖的，通过观察所述监测器5正面的弹性膜的状态，即可判断皮肉组织是否具有浮肿倾向，以便于及时发现和调整输液针1的不当位置状态。
对于所述监测器5，其实施例二如图3、图4所示，与实施例一不同的是，所述圆形腔体50正面的弹性膜为透明膜，所述圆形腔体50的内底面上制有一道色环53；所述圆形腔体50上方还覆盖一个透明罩盖54，该透明罩盖54与所述弹性膜之间具有间隔，且所述透明罩盖54上制有径向延伸的刻度线。按照该实施例二，当所述弹性膜向上膨胀凸起时，所述圆形囊便构成一个凸透镜，从而使从所述监测器5的正面看，其内底面的色环53直径将增大，增大量由所述透明罩盖54的刻度线示出，从而更方便，且更准确地观察圆形囊的当前压力。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换，均应包含在本发明的保护范围之内。
