Post-operative blood loss monitoring device: A new tool for nursing activities

Summary:In most medical specialties, after surgery, it is usual to place a drain at the operative site level, in order to assist the blood flow-out if necessary. This drainage allows avoiding the formation of hematomas and contributes to tissues recovery. However, postoperative blood loss can lead to serious consequences. Also, it is necessary to continuously check the blood output volume in order to be able to intervene quickly in case of too significant losses. In daily clinical practice, this task is due to the nursing staff that periodically records the blood level inside the supple bag connected to the drain. However, this method is not accurate about the volume of lost blood and does not reflect the flow of losses which is an important parameter regarding the evolution of the patient setting. We have designed and developed a prototype of a blood loss monitoring device based on the continuous weight measurement of the blood bag connected to the drain. This device is fixed on the bed and is able to instantaneously alert the medical staff in case of abnormal blood flow-out.
