输液镇痛电磁热毯
摘要
静脉输液法是人们日常生活中治疗疾病常见且疗效最佳的一种给药方法。但在静脉输液过程中,往往会引起患者针眼、穿刺局部、肢体和静脉走行部位疼痛、酸、麻、困、胀、冷等不良反应,尤其是长期滴注刺激性药物、化疗药物、高营养制剂时尤为明显,因此镇痛在静脉输液治疗中的意义越来越重要。如能在静脉输液过程中及时、快速地减轻患者的痛苦,则对整个治疗的效果有着重要的作用。
此次设计的输液镇痛仪是应用电热磁疗镇痛技术,采用温度传感器作为测温器件,并由单片机做微处理器进行数据处理以实现对温度的显示和恒温控制。利用电热丝给正在输液的患者手臂加热,并由磁钢产生恒定的强磁场,直接作用于患者输液的手臂。通过恒定强磁场和电热丝发热,给手臂进行热疗和磁疗,以此降低神经末梢的兴奋度,提高痛阀,缓解疼痛;增加输液局部血液循环,改善局部细胞的营养,加速病理产物及代谢产物的排泄,促进渗出物吸收,使病人在非常舒适的状况下完成整个输液过程。
此输液镇痛仪通过加热和磁疗的物理方法,对患者进行镇痛治疗,无任何副作用,具有体积小、使用方便、价格低等优点。

ic heat blanket of infusion analgesia hardware design
ABSTRACT
Intravenous infusion method is the best and mon method that has a curative effect in treating disease in people's daily life. But in the intravenous infusion process, it often can cause the patient to the eye of a needle, injection site, limbs and venues’ pain, acid, hemp, trapped, expansion, cold and other adverse reactions, especially long-term infusion of irritant drugs, chemotherapeutic agents, and high nutrition is particularly evident, therefore analgesia in intravenous infusion treatment is ing more and more important. If in the intravenous infusion process alleviating the suffering of patients can be in time, it will play an important role to the entire treatment.
The design of the Infusion Analgesia meter is the application of electric ic therapy analgesic techniques, with the temperature sensor for temperature measuring, and the chip microprocessor for data processing to achieve the temperature display and temperature control. Heating wire is used for heating transfusion patients' arm, and generating a constant ic field which directly act on the transfusion arm. Using the constant ic field and the heating wire make arm have a hyperthermia and o therapy, which can reduce the nerve endings of the excitement, increase threshold of pain tolerance, relieve pain, increase the infusion of local blood circulation, impr
