Haemonetics公司开发出具有自我调节功能的外科泵

 
 
Haemonetics公司设计开发了一种新型外科泵叫做Harmony系统，该系统能够产生高压气流，能够自我调节从较低水平的外科手术区域抽出液体。

这种无需支撑物的Harmony系统，取代了围墙式抽吸，有效地增加了外科医生从手术区域清除液体的能力，能够收集患者的红细胞，重新回输给患者。在自动处理过程中，这种收集的血液是清洁的，能够回输给患者。这就确保了患者能够得所能得到的最安全的血液：他们自身的血液。

Harmony系统综合了较高抽吸速度和血液细胞恢复所需要的较低的真空压力，这就免除了调节抽吸水平的麻烦。该系统专门设计用于Haemonetics公司(Braintree, MA, USA; www.haemonetics.com)的OrthoPat、CardioPat和细胞救助自动输血系统。

Self-Regulating Suction Pump
 
A new surgical pump provides high air flow and self-regulating suction to remove fluid from the surgical field at low-suction levels.

The free-standing Harmony system, which replaces wall suction, is designed to improve the ability of surgeons to clear fluids from the surgical field and collect the patient’s red cells for re-use in the patient. In the automation process, this collected blood is cleaned and made available for transfusion back into the patient. This ensures that patients receive the safest blood possible: their own.

The Harmony system combines high suction rates with the low vacuum pressures needed for the best blood cell recovery, while eliminating the need to adjust suction levels. The system is specifically designed to supply suction for the OrthoPat, CardioPat, and Cell Saver autotranfusion systems of Haemonetics Corp. (Braintree, MA, USA; www.haemonetics.com), which developed Harmony.
