Problems solved by technology

When using oxygen, air or other gases, gas embolism may occur and cause danger
[0005] At present, one of the devices used to detect whether the fallopian tubes are unobstructed is the "Tubal Ventilator" disclosed in Chinese utility model patent 90206313.8. And measurement, so the measurement accuracy of gas flow, pressure and other indicators is not very high, and these two indicators are an important basis for doctors to diagnose and treat patients
In addition, the device has only one pressure limiting protection method, so the safety of the device needs to be improved

Embodiment Construction

[0014] figure 1 Is the basic principle block diagram of the present invention. Such as figure 1 As shown, the device of the present invention mainly includes: a control device 11 , a flow controller 12 , a flow sensor 13 , a pressure sensor 14 and a tubal ventilation plug 5 . The main operating principle of the device is as follows: carbon dioxide gas flow (or any other suitable gas flow, the principle of the present invention has nothing to do with the type of gas used) is controlled at a flow rate between 30-60ml / s after passing through the flow controller 2. The specific control situation is set by the control device 11 . The airflow coming out from the flow controller 12 passes through a flow sensor 13, and the flow sensor feeds back the measured flow data to the control device 11, and the control device 11 compares the amount measured by the flow sensor 13 with the preset flow controller 12 If the amount measured by the flow sensor 13 is larger than the preset amount, ...

Abstract

The oviducal insufflator includes insufflating duct, flow rate controller for controlling the air flow inside the insufflating duct, flow rate sensor for detecting the air flow inside the insufflating duct, pressure sensor for detecting the air pressure inside the uterine cavity, and control unit connected to the flow rate controller, the flow rate sensor and the pressure sensor. The control unit is used for setting and regulating the flow rate of the flow rate controller, reading out flow rate data from the flow rate sensor and reading out data from the pressure sensor. The working process includes setting air flow rate; detecting air pressure inside the uterine cavity regularly; sending alarm in case of abnormal air pressure inside the uterine cavity; reading out data from flow rate sensor regularly; sending alarm in case of abnormal flow rate; and outputting the air pressure inside the uterine cavity varying with time.

Description

technical field [0001] The invention relates to a device and method for detecting whether the fallopian tubes are blocked, in particular to a device for detecting whether the fallopian tubes are blocked by using an airflow with a certain pressure and flow rate. Background technique [0002] Whether the fallopian tubes are unobstructed and function normally is an important condition to determine the fertility of women. The patency of the fallopian tubes can make the sperm and eggs meet and fertilize, but this is not enough. The normal peristalsis of the fallopian tubes is also required to transport the fertilized eggs to the uterus for implantation and development. Among various tubal patency examinations and treatment methods, only tubal ventilation can simultaneously check the patency of the fallopian tube and whether its peristaltic function is intact. [0003] A large number of medical research data point out that when CO2 gas or some kind of gas with anti-inflammatory e...
