AI Technical Summary

Problems solved by technology

Clinically, it is still a blind spot to accurately judge the amount of flushing fluid absorbed and the amount of bleeding during surgery, especially after the blood is mixed with the flushing fluid, it increases the difficulty of judging and evaluating the amount of bleeding and fluid absorption; for this reason, we developed A detection and control system for irrigation fluid absorption and bleeding in endoscopic surgery to improve the safety of endoscopic surgery

Embodiment 1

[0023] Such as figure 1 As shown, the effluent collection device 3 is connected to the photoelectric sensor 6, and the hemoglobin concentration of the effluent measured by the photoelectric sensor 6 is analyzed in real time through the analysis system II7, and then according to the patient's preoperative hemoglobin concentration and the measured effluent volume , the bleeding volume of the patient during the operation can be calculated, and the calculation formula is as follows:

[0024] Intraoperative blood loss = (effluent hemoglobin concentration × effluent volume) / preoperative hemoglobin concentration

[0025] The detection is accurate and fast, and the safety of the operation is improved.

[0026] The inflow of the rinsing liquid is calculated by the non-contact real-time detector 1 using the method of micro-decreasing weight, combined with the density of the rinsing liquid; pressure sensor to detect.

Abstract

The invention relates to medical instruments, in particular to a flushing fluid absorption and bleeding detection control system in an endoscope operation. The flushing fluid absorption and bleeding detection control system in the endoscope operation comprises a non-contact real-time detector (1), an analysis system I (2), an effluent collecting device (3), a weighing system (4) and a display system (5). The effluent collecting device (3) comprises an effluent collecting bucket (301), a photoelectric converter (302) and an analog-digital converter (303), the effluent collecting bucket (301) is sequentially connected with a photoelectric sensor (6) and the effluent input end a, the photoelectric sensor (6) is connected with the photoelectric converter (302), and the analog-digital converter (303) is connected with the photoelectric converter (302) and sequentially connected with an analysis system II (7) and the weighing system (4). The analysis system II (7) is sequentially connected with the display system (5), the analysis system I (2) and the non-contact real-time detector (1). The flushing fluid absorption and bleeding detection control system has the advantages of being accurate and fast in detection and improving safety of the operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a detection and control system for flushing fluid absorption and bleeding in endoscopic surgery. Background technique [0002] In the past two decades, the development of endovascular surgery has changed the history that medicine must use open surgery to treat urinary and female reproductive system diseases. The development of endoscopic resection, percutaneous nephroscopic technique and subuterine endometrial resection in their respective fields. [0003] Benign prostatic hyperplasia is one of the most common diseases in elderly men, and TURP has become the main method for treating benign prostatic hyperplasia in my country. TURP has the advantages of wide indications, short operation time, small trauma, fast postoperative recovery, short hospital stay, and significant curative effect. PCNL is an important part of endourological surgery. At present, more than 90% of pa...
