摘要：
Infusion pumps that do not require electricity for operation are disclosed for various applications, including but not limited to pharmaceutical delivery of medications. A substance, which can be liquid, is stored in a reservoir and driven pneumatically by pressure generated by thermal transpiration, which requires a temperature difference existing between two ends of a narrow channel. In the case of pharmaceutical delivery, the medication is delivered to the treatment site via an applicator. Power sources other than electricity include, but are not limited to, the temperature of a persons body heat exceeding the ambient temperature of surrounding air.
