Sample sampling device for screening early gastric cancer by gastric lavage fluid

Abstract

The invention discloses a sample sampling device for screening early gastric cancer by gastric lavage fluid. The device comprises a first support plate and a temperature control structure, wherein the temperature control structure comprises a temperature control shell, a first motor, a partition plate, a second motor, a first threaded column, a sliding plate, limiting columns, a wireless temperature measuring device, a receiving and displaying assembly and a heating body, wherein the temperature control shell is fixedly connected to the top of the first support plate, the first motor is fixedly connected to the top of the temperature control shell, a stirring assembly is arranged at the output end of the first motor, the partition plate is fixedly connected to the bottom of an inner cavity of the temperature control shell, the second motor is fixedly connected to the top of the temperature control shell, and the first threaded column is fixedly connected to the output end of the second motor; and the surface of the first threaded column is in threaded connection with the sliding plate which is slidably connected to the surfaces of the limiting columns. The sample sampling device has the beneficial effects that the sample sampling device for screening the early gastric cancer by the gastric lavage fluid, which is convenient for temperature control and height adjustment and is relatively stable, is provided.

Description

technical field [0001] The application relates to a sampling device, in particular to a sample sampling device for gastric lavage fluid screening for early gastric cancer. Background technique [0002] Gastric cancer is a malignant tumor originating from the gastric mucosal epithelium, and its incidence is increasing year by year. The incidence of gastric cancer in my country accounts for 50% of the world, and it is the second major cause of cancer death in my country. Due to the lack of specific symptoms in the early stage of gastric cancer, more than 85% of gastric cancer patients It was already in the advanced stage when diagnosed, and the prognosis of most patients with gastric cancer is poor, with high mortality and metastasis rates. %, and the 5-year survival rate of patients with early gastric cancer after surgical treatment can exceed 90%, and even achieve the effect of cure. The current clinical serological tests mainly include pepsinogen (PG), gastrin-17 (G-17 ) and ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the shortcomings of the existing technology, the temperature control structure is used to heat the gastric lavage fluid and keep the temperature of the gastric lavage fluid close to the temperature of the human stomach, which solves the problem that the temperature of the gastric lavage fluid is difficult to control and causes patients to Feel uncomfortable, at the same time, use the first threaded column to drive the wireless temperature measuring device to move up and down, which can comprehensively monitor the temperature of gastric lavage fluid, solve the problem of uneven temperature of gastric lavage fluid, and facilitate the monitoring of gastric lavage fluid. temperature control

[0005] In order to solve the problems in the prior art, the height adjustment structure is used to adjust the height of the temperature control structure, which solves the problem that it is difficult to sample patients at different heights, and facilitates the sampling of early gastric cancer samples for gastric lavage fluid screening

[0006] Further, in order to solve the problems in the prior art, the use of the stable structure can increase the contact area between the device and the ground, making the device more stable during use, solving the problem that the device is unstable and prone to movement during sampling, and preventing the device from moving to affect sampling carry out
