Device for monitoring water inlet and outlet quantity in real time in operation

Technical Field

The utility model relates to a monitoring of the water yield of cominging in and going out in the art, a device of real-time supervision water yield of cominging in and going out in the art specifically says so.

Background

Endoscopic surgery in hospitals is now more and more popular, such as gynecological hysteroscopic surgery, urological transurethral prostatectomy, transurethral cystourethry electrocision, percutaneous nephroscope surgery, ureteroscope and the like, in the process of the surgery, doctors must wash the resection part with special liquid through a pipeline to keep the surgical field clear, and simultaneously reduce the temperature of the liquid in the electrocision mirror surgery. However, in the process of hysteroscopic surgery, due to the effects of the uterine distention pressure and the perfusion medium, a large amount of perfusion liquid is absorbed by the surgical wound surface and enters the circulatory system of a human body, so a series of clinical symptoms such as fluid overload and/or dilution hyponatremia are caused, if death is caused by not timely discovering and treating, the uterine cavity is one of serious complications of the hysteroscopic surgery. This complication is also known as TURP syndrome. The prevention of TURP syndrome mainly includes the following four aspects: (1) reasonable uterine cavity pressure; (2) reducing blood sinus patency; (3) monitoring the liquid uptake; (4) and controlling the operation time. It is an extremely important means to accurately calculate the amount of fluid taken in and out during surgery to determine the amount of fluid absorbed. Because the input amount is suspended physiological saline or swelling liquid such as mannitol and the like, and the output amount is polluted waste, both the input amount and the output amount cannot be accurately calculated, and no method for effectively calculating the water input and output amount clinically exists at present. Therefore, a system capable of monitoring the water inflow and outflow amount in real time under a hysteroscope is urgently needed, the absorption amount of a patient to liquid is judged, a doctor is prompted and correspondingly treated by setting a certain warning value, and the occurrence of complications is effectively reduced. The literature indicates that the maximum absorption of hypotonic non-electrolyte perfusate is 1000mL for healthy people, while the maximum absorption of isotonic fluid is less clear than the expert's recommendations < 2000mL, and the individual condition of the patient and the recommendations of the anesthesiologist should be considered. If hypertonic fluids are used, the maximum absorption should not exceed 500mL, and absorption < 300mL for elderly or patients with impaired cardio-pulmonary function should be given a high degree of vigilance for patients with impaired cardiac or renal function. The alert value can be set accordingly.
