Vomit sampling device for digestive department detection

Abstract

The invention discloses a vomit sampling device for digestive department detection, which relates to the field of medical instruments. The problem that an existing device is prone to being polluted by vomit is solved. The equipment specifically comprises a bottom plate, a placement box is fixedly connected to the outer wall of the top of the bottom plate, and a cover plate is fixedly connected to the outer wall of the top of the placement box. By arranging a containing assembly, the sliding shaft moves to drive the circular truncated cone to slide along the inner wall of the straight pipe, and when the top of the circular truncated cone slides to the bottom of the plug frame, due to the fact that the straight pipe is located in the vomit environment, materials enter the inner wall of the straight pipe through the plug frame, then the sliding shaft ascends, and the circular truncated cone drives the materials to ascend to continuously convey the materials into the funnel barrel; when the circular truncated cone returns to the original position due to the action of the elastic telescopic column, the movable block already seals the space of the inner wall of the straight pipe at the bottom of the funnel barrel, surface materials are separated out, the vomit transportation distance is fundamentally shortened, and meanwhile the containing assembly can be separated from the device, and subsequent cleaning is facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a vomitus sampling device for gastroenterology testing. Background technique [0002] During the treatment in the gastroenterology clinic, the co-stimulation of food and drugs is likely to irritate the stomach of the patient and cause vomiting, and the laboratory analysis of the vomitus can quickly determine the cause of vomiting, thereby changing the treatment method. Vomit sampling devices hold even more promise. [0003] After searching, the Chinese patent application number is 201910120121.2, which discloses a vomit sampling device for gastroenterology nursing, including a sampling cylinder, the bottom of the sampling cylinder is connected with a sealing screw cap through a hinge, and the top of the sampling cylinder is A sliding tube penetrating through the sampling cylinder is slidably embedded in the center, and a first partition is fixedly connected to the inner side of th...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have the following deficiencies: the traditional negative pressure extraction method is used, but for vomitus, once the negative pressure extraction is performed through the pipeline, it faces the risk of contamination of the movement channel of the entire device, and the next pathological sampling work is required , its cleaning cycle must be longer, so there are too many shortcomings of pipeline transportation, which needs to be improved
