Abstract

临床输液用末梢型恒温加热器是一种临床医疗 输液用加温设备,属于医疗电子器械技术领域。在该 设备中,导热体的一端埋设热源,其另一端构成一个 适当的间隙用于夹持输液器管近末端。热源采用正 温系数陶瓷发热元件(PTC),以PTC的温度自限性 实现温度控制达到恒温效果。

Description

本实用新型涉及医疗输液的加热,使临床输液过程中的药液温度符合人体生理状况。
目前在临床输液过程中,药液与人体温度相差过大。特别在冬季无暖气设备或是直接取用刚刚解冻、冷藏的药液时,常使接受输液的患者感到寒冷难当,增加了病患者的痛苦,影响治疗的实施。医疗单位为此采取各种措施以期改变这一状况,如将药液加温后使用或是在使用时以热水袋加温等,但均有这样那样的缺点,以致临床效果很不理想。本实用新型采用正温系数陶瓷发热元件(PTC)作为热源,具有结构简单、使用方便、温度恒定、安全可靠、节能耐用的特点。临床输液时,将其安装在输液器皮管靠近末端处,利用PTC的温度自控作用,取得适合人体的恒定温度,使药液得到加温。加温后的药液即时进入人体,因而具有很高的热效率。
附图是加热器结构示意图。图中[1]为热源,采用正温系数陶瓷发热元件(PTC),加电后产热,并使温度控制在设计温度。[2]为导热体,夹持输液器管[4]壁并将热量传导给药液。[3]为外壳,起减少加热器热损失及防护、美观作用。

Claims (2)

1、一种临床输液用末梢型恒温加热器,由热源[1]、导热体[2]和外壳[3]组成,其特征在于导热体[2]的一端埋设热源[1],另一端构成一个适当的间隙用于夹持输液器管[4]。
2、根据权利要求1所述输液用末梢型恒温加热器,其特征在于用正温系数陶瓷发热元件(PTC)作为热源[1]。
