Embodiment 1

[0030] see figure 1 , figure 1 It is a schematic diagram of the self-developed solid-state high-resolution esophageal manometry system verification device. The first temperature probe 8, the second temperature and humidity probe 10, and the pressure probe are sealed in a sealed cylinder 1 with a height of 500 mm and a diameter of 100 mm, and is equipped with a pressure regulating valve 5, a pressure relief valve 4 and a digital pressure gauge 9 to adjust the display Cylinder internal pressure, so that the internal pressure of the sealed cylinder 1 can be continuously adjusted within (0-40) kPa (0-300mmHg).

[0031] The device is equipped with a high-precision temperature and humidity probe with a digital temperature controller to display and control the working temperature, and is equipped with a humidity indicator to display the humidity in the cylinder. The digital temperature controller adopts PID fuzzy control. Such as figure 1 As shown, a heater 3 is placed at the low...

Embodiment 2

[0042] The difference from Example 1 is that, see figure 2 , the sealed cylinder 1 is also coaxially fixed with an air guide tube 15, the upper and lower ends of the air guide tube 15 are open, and the lower end is aligned with the heater 3; the first temperature probe 8, the second temperature probe 10. The pressure probes 9 all extend into the air guide tube 15 . Both the heater 3 and the fan 2 are within the range corresponding to the lower opening of the air guide tube 15 . The air guide tube can promote the circulation of the gas in the sealed cylinder and improve the uniformity of the gas temperature in the device.

[0043] All the other are the same as embodiment one.

[0044] Embodiment 2 is a preferred embodiment.

Abstract

The invention relates to a device to detect a solid esophageal manometry system. The device comprises a sealed barrel; a heater is arranged at the bottom of the sealed barrel; a fan is arranged belowthe heater; a hose of the solid esophageal manometry system is extended from the top of the sealed barrel into the sealed barrel; one segment of the hose is a manometry catheter; the part, corresponding to the upper end of the manometry catheter, of the sealed barrel is provided with a first temperature probe, the part corresponding to the lower end of the manometry catheter is provided with a second temperature probe, and the part corresponding to the middle of the manometry catheter is provided with a pressure probe; the sealed barrel is also provided with a pressure adjusting valve and a pressure relief valve; the first temperature probe, the second temperature probe, the pressure probe are electrically connected with a monitoring system. The device having uniform controllable humidityand continuously adjustable interior pressure can provide effective measurement for a solid high-resolution esophageal manometry system.

Description

technical field [0001] The invention relates to a device and method for detecting a solid-state esophageal manometry system, belonging to the technical field of medical device detection. Background technique [0002] Gastroesophageal reflux disease is a digestive tract motility disorder disease caused by various factors. Among them, the relaxation and pressure reduction of the upper esophageal sphincter, esophageal body, and lower esophageal sphincter cause abnormal esophageal structure and esophageal motility dysfunction, leading to Stomach contents are more likely to reflux into the esophagus, which is a major factor in the development of gastroesophageal reflux disease. [0003] High-resolution esophageal manometry is currently the "gold standard" for monitoring esophageal motility. Its measurement principle is to insert a monitoring catheter with multiple pressure sensors into the stomach through the patient's nasal cavity, and detect the UES, body, LES and stomach acco...
