Infusion Pump – NSL ST1000 Samtronic (Brazil)

一个输液泵注入fluids,medicationornutrientsinto a患者circulatory system。通常使用intravenously，，，，althoughsubcutaneous，，，，动脉and硬膜外偶尔使用输注。

如果护理人员手动执行，输液泵可以以不切实际或不可靠的方式管理流体。例如，它们可以每小时注射0.1毫升（太小，无法滴入），每分钟注射，注射重复bolusesrequested by the patient, up to maximum number per hour (e.g. in患者控制的镇痛），或者的体积因一天中的时间而异。

Because they can also produce quite high but controlledpressures，它们可以皮下（皮肤下方）或表演（仅在central nervous system– a very popular local spinal麻醉为了childbirth).

这用户界面泵通常要求有关将其设置为技术人员或护士的输液类型的详细信息：

• 连续输注usually consists of small pulses of infusion, usually between 500 nanoliters and 10 milliliters, depending on the pump’s design, with the rate of these pulses depending on the programmed infusion speed.
• Intermittent infusion具有“高”输注率，以低的可编程输液率交替cannulaopen. The timings are programmable. This mode is often used to administerantibiotics，或其他会刺激血管的药物。

To get the entire dose of antibiotics into the patient, the “volume to be infused” or VTBI must be programmed for at least 30 CCs more than is in the medication bag…or else up to half of the antibiotic will be left in the IV tubing.

• Patient-controlled是按需输液，通常带有预编程的天花板以避免中毒。该费率由患者可以激活的压力垫或按钮控制。这是选择的方法患者控制的镇痛（PCA），其中重复的小剂量opioid镇痛药交付，该设备编码以停止给药，然后再达到可能导致危险呼吸抑制的剂量。
• Total parenteral nutrition通常需要类似于正常进餐时间的输液曲线。

Some pumps offer modes in which the amounts can be scaled or controlled based on the time of day. This allows for昼夜节日which may be required for certain types of medication
