A device for recovering target components of medical cavity contents

Abstract

The invention belongs to the field of medical devices, and relates to a medical device for recovering targeted components of a cavity content. The device recovers the targeted components of the human body cavity content in vitro. The device can be used for greatly preparing a fecal bacterium solution with parasitic ova removed to support a preparation procedure of standardized fecal bacterium transplantation, used for greatly collecting the parasitic ova in a fecal suspension to increase a positive detection rate of the parasitic ova, used for collecting deslagged secretions in intestine and stomach cavities by an endoscope to meet requirements of checking and diagnosis, used for collecting lavage liquid in a trachea and removing slag by the endoscope to meet requirements of a hormone test and cytological examination, and used for collecting liquid of biliary and pancreatic ducts and a urogenital canal to meet requirements of the checking and the cytological examination. The method solves the practical problems of clinical applications, and has important innovation and an application value.

Description

technical field [0001] The invention relates to a device composed of a suspension container, a step-by-step filter device and a target component collection device, in particular to a medical device for recovering target components from the contents of a human cavity, and belongs to the technical field of medical devices. Background technique [0002] The contents of the human gastrointestinal tract include food residues, flora, parasite eggs and other active components, as well as body fluid components secreted by the intestinal tract, foreign bodies and liquids that enter the cavity due to various reasons, and endoscopic Finely divided tumor tissue that has been resected but is not easy to remove directly. In the clinical and research process, the only way to distinguish and obtain these target components is to rely on effective instrument-assisted separation. Taking the clinical background of preparing fecal bacteria transplantation liquid and collecting a large number of...

Problems solved by technology

[0004] Since the development of science, although there have been a few studies on the delivery of fecal suspension or fecal suspension into the gastrointestinal tract through colonoscopy, gastroscopy, nasogastric tube, jejunal tube, capsules, etc., to achieve fecal bacterial transplantation, these methods exist. The following problems: (1) The medical staff who prepare the feces suffer from the visual and psychological discomfort of the feces, and some even refuse these jobs; (2) The non-standardization of the preparation procedure will lead to an increase in the labor cost of the treatment procedure; (3) Previous studies were all about how to avoid the possibility of parasite intestinal infection of feces, which lacks a new breakthrough in the methodology of fecal microbe transplantation, that is, while obtaining the bacterial fluid, it is necessary to effectively filter out worm eggs to prevent parasitism Insect infection, while also filtering out other impurities and odors as much as possible; (4) Conventional artificial filtration measures are difficult to ensure reliable and controllable quality of fecal bacteria samples

[0006] Another clinical need is to use endoscopically aspirated gastrointestinal fluid for laboratory testing, the main purpose of which is to obtain liquid components, however, various solid components such as food residues must be mixed during the suction process; The aspirated bladder fluid is used for laboratory examination, and its main purpose is to obtain the liquid and exfoliated cells and other formed components. However, solid components such as stones and other large residues in the urine may be mixed during the suction process; Tracheal endocrine fluid and lavage fluid, the main purpose of which is to obtain liquid and exfoliated cells and other formed components, however, it is mixed with obvious tissue pieces and thick sputum, etc.
