Technical Field

The invention relates to the technical field of medical instruments, in particular to a metering device and a metering method for a hysteroscope water inlet and outlet monitoring voice alarm liquid retention amount.

Background

Hysteroscopic surgery is a minimally invasive gynecological diagnosis and treatment technology used for intrauterine examination and treatment, and comprises a hysteroscope, an energy system, a light source system, a perfusion system and an imaging system; the anterior part of the endoscope body is used for entering the uterine cavity, and the endoscope has an amplifying effect on the observed part, so that the endoscope has the visual and accurate advantage of being the first choice for examining the gynecological hemorrhagic diseases and intrauterine lesions. When hysteroscope operation is performed, the uterus is filled by injecting the distension Gong Ye into the uterine cavity through the water inlet channel, then the water outlet channel is opened to enable the liquid in the uterine cavity to dynamically flow and enter and exit the uterine cavity to be balanced, meanwhile, the clot and impurities in the uterine cavity are discharged, so that the visual field is clearer, various changes in the uterine cavity can be clearly observed, in the actual use process, the air in the water inlet pipe needs to be firstly emptied, the light source is turned on, the hysteroscope is slowly placed, the distension Gong Ye (5% glucose solution or physiological saline) is injected, the distension pressure is controlled to be 13-15kPa (1 kPa=7.5 mmHg), after the uterine cavity is filled, the visual field is bright, and the hysteroscope can be rotated for sequential comprehensive observation.

Currently, this water injection and drainage procedure using perfusion systems with hysteroscopic surgery requires manual observation and measurement: the liquid inlet amount is measured by a graduated capacity device (the liquid in the body is discharged to the interface of a sewage container), so that whether the patient is in a safe state during the operation is judged by calculating the result of the difference between the liquid accumulated in the body and the liquid accumulated in the body. The following problems still exist in practical work:

1. At present, a nurse monitors the human body absorption amount, which is the liquid amount entering the uterine cavity (namely, the weight of an original water bag is weighed, the weight of the water bag is weighed in real time in operation), and the visceral water liquid volume of the uterine cavity is discharged from the barrel (the weight of default physiological saline is 1:1). However, the manual measurement lacks real-time monitoring, and sometimes the high-risk operation access amount can be different by more than 1000ml in a short time, and if the liquid amount entering the human body is excessive in a short time, water poisoning and even life threatening can be caused.

2. In the operation process, the intrauterine tissue can be discharged along with liquid at the same time, so that samples which need to be detected are often arranged in the intrauterine tissue, and the existing technology sometimes causes the loss of the samples.

3. Meanwhile, the coagulum and impurities can cause inaccuracy of liquid accumulation difference of water inlet and outlet in the metering and comparison process after being discharged.
