用输液泵可将药物输送到靶器官,泵可分成三种类型:(1)外用便携式,(2)植入式,(3)具有特殊传感器的植入式。外用便携式可用于严重连续疼痛及糖尿病患者;植入式在抗癌化疗领域中已取得良好的临床效果。这些植入式输液泵的特点是具有电渗透泵或蒸气压泵那样的自身推动源。本文主要介绍一种可以从外部调节药物输出速率的植入式输液泵。该泵由两部分组成,一是容器,二是外部控制装置。容器包括药室、注射泵、齿轨、小齿轮、塑料园盘和一根300G3.4cm长的磁棒。其工作原理是由外部控制装置中
Pumps deliver drugs to target organs. Pumps fall into three categories: (1) external portable, (2) implantable, and (3) implantable with special sensors. External portable for severe continuous pain and diabetes patients; implantable in the field of anticancer chemotherapy has achieved good clinical results. These implantable infusion pumps feature a self-propelled source such as an electro-osmotic pump or a vapor-pressure pump. This article describes an implantable infusion pump that can externally regulate the rate of drug delivery. The pump consists of two parts, one is the container and the other is the external control device. The container consists of a pouch, syringe pump, rack, pinion, plastic disc and a 300G 3.4cm long magnet bar. Its working principle is in the external control device
