Negative pressure suction system

Abstract

The invention relates to the technical field of medical monitoring systems, in particular to a negative pressure suction system. The negative pressure suction system comprises a suction device, a storage device, a monitoring device and a calculation module, wherein the suction device is used for sucking mixed liquid generated in an operation; the storage device is used for storing the mixed liquid sucked by the suction device; the monitoring device is used for monitoring the volume of the mixed liquid in the storage device, and the device is also used for measuring the intraoperative Hb value of the mixed liquid and used for collecting the weight of blood immersion gauze of blood-carrying gauze during the operation; the calculation module is used for obtaining the preoperative Hb value and calculating the suction bleeding amount according to the volume, the intraoperative Hb value and the preoperative Hb value, and the calculation module is also used for obtaining the weight of dry gauze and calculating the infiltration bleeding amount according to the weight of the dry gauze, the weight of the blood immersion gauze and the preset unit blood immersion amount and superposing the suction bleeding amount and the infiltration bleeding amount to generate the intraoperative bleeding amount. According to the negative pressure suction system, the accuracy of pre-estimating the bleeding amount in the operation can be improved.

Description

technical field [0001] The invention relates to the technical field of medical monitoring systems, in particular to a negative pressure suction system. Background technique [0002] During the operation, in order to ensure a clear surgical field of view, it is necessary to absorb the liquid generated during the operation in time, for example, use gauze to absorb the liquid in the surgical field of view, or use a negative pressure suction device to directly absorb the liquid in the patient's body. During the operation, it is also necessary to estimate the bleeding volume of the patient in time, so as to judge whether it is necessary to infuse the patient, so as to avoid the excessive blood loss of the patient, which may lead to medical accidents. [0003] In the prior art, the amount of bleeding is estimated according to the suction method of the patient's body fluid. If gauze is used to absorb blood, the amount of bleeding is estimated based on the amount of gauze used durin...

Problems solved by technology

However, in some special operations, such as caesarean section, the fluid produced by the patient will include amniotic fluid, blood, and other tissue fluids, etc. The amount of bleeding obtained by directly estimating the amount of fluid has a large error, and the doctor cannot get a more accurate bleeding It is very likely to mislead the correct assessment and judgment of the doctor during the operation, and increase the possibility of medical accidents
