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

Embodiment

[0047] A negative pressure suction system, such as attached figure 1 As shown, it includes a suction device, a storage device, a monitoring device, a computing module, a storage module, a data acquisition module, a data calling module, a strategy adjustment module, a first judgment module, a reminder module and a second judgment module.

[0048] The suction device is used for suctioning the mixed solution produced during the operation, the storage device is used for storing the mixed solution suctioned by the suction device, and the suction device and the storage device are communicated through a suction pipe.

[0049] The monitoring device is used to monitor the volume of the mixed solution in the storage device; it is also used to measure the intraoperative Hb value of the mixed solution; it is also used to collect the weight of the blood-soaked gauze with blood in the operation. Specifically, the monitoring device includes a micro liquid level gauge, a hemoglobin analyzer a...

Abstract

The present invention relates to the technical field of medical monitoring systems, in particular to a negative pressure suction system, comprising: a suction device used to aspirate the mixed liquid generated during surgery; a storage device used to store the mixed liquid sucked by the suction device The monitoring device is used to monitor the volume of the mixed solution in the storage device; it is also used to measure the intraoperative Hb value of the mixed solution; it is also used to collect the blood-soaked gauze weight of the bloody gauze in the operation; the calculation module is used to obtain the preoperative Hb value, calculate aspiration blood volume based on volume, intraoperative Hb value and preoperative Hb value; also used to obtain dry gauze weight, calculate infiltration blood volume based on dry gauze weight, blood-soaked gauze weight and preset unit blood immersion volume ; The aspiration blood volume and the infiltration blood volume are superimposed to generate the intraoperative blood volume. Adopting this scheme can improve the accuracy of intraoperative blood loss estimation.

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, such as using gauze to absorb the liquid in the surgical field, or using 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 amount of blood loss of the patient in time, so as to determine whether it is necessary to infuse the patient to avoid excessive blood loss and 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 gauze used in the operation is used to estimate the amount of bleeding; Estimate blood loss. ...
