Abstract

The utility model relates to a medical sample used for solving the inconvenience in sampling intestinal juice by instruments. The utility model is an intestinal juice sampling device. The utility model is a hollow granular object with a size equivalent to an oral pill. The utility model is composed of an external layer, a middle layer and an internal layer. The utility model is characterized in that the internal layer is made of hard inert materials, the middle is a vacuum hollow, the internal layer wall is provided with a normally open sampling hole connecting and communicating with the hollow; the middle layer is made of elastic inert materials, the wall of the middle layer is provided with a gap facing the normally open sampling hole on the internal layer, and an external wrapping of the middle layer is the external layer made of intestinal juice materials. The utility model is used for sampling intestinal juice.

Description

The intestinal juice sampler

This utility model relates to medical sampler, especially refers to a kind of intestinal juice sampler.

Have now and medically getting intestinal juice in human body intestinal canal, use mechanical implement often, this at first sight strikes fear into to patient, in using, practice can bring misery to patient, because of than, the sampler of this apparatus formula has been subjected to certain restriction in the use, to some patient even can't use.These shortcomings fundamentally are to be difficult to overcome concerning mechanical type intestinal juice sampling apparatus, even can't overcome.

The purpose of this utility model provides a kind of and the very little intestinal juice sampler of the distinct volume of mechanism's formula intestinal juice sampler.

The purpose of this utility model is achieved in that the intestinal juice sampler, it is one and the sizable hollow particle shape of oral medicine pill object, form by skin, middle level, nexine, it is characterized in that: nexine is made by the hard inert material, the centre is that vacuum is hollow, layer wall be provided with one with hollow be connected often open thieff hatch; The middle level is made by whippy inert material, is provided with the slit facing to the thieff hatch of often opening on the nexine on its wall, and the middle level outer wrapping is the skin of being made up of the enteric solubility material.

When above-mentioned design is used, sampler is sent into digestive tract with oral method.The sampler skin begins dissolving after entering intestinal, and outer molten the breaking that thieff hatch is outer is because sampler inside is vacuum, intestinal juice is inhaled in the sampler, when inside and outside differential pressure drops to a certain degree, and the sampling slit closure on the middle level, sample is stored in the sampler, up to excreting.Change outer field thickness, just can change sampling opportunity, thereby can obtain the intestinal environment sample of different intestinal segments.After the sampler that excretes reclaims, take out inner sample, just can carry out the analysis and research of various means sample.

Below by drawings and Examples this utility model is described further again.

The organigram that Fig. 1 amplifies for this utility model;

As shown in the figure: this utility model ovalize also can be designed to sphere.Be one and the sizable granular substance of oral medicine pill, constitute by skin 3, middle level 2 and nexine 1, nexine 1 is made by hard inert material, the centre is a vacuum hollow 6, layer wall be provided with one be connected with hollow 6 often open thieff hatch 4, middle level 2 is made by whippy inert material, is provided with slit 5 facing to the thieff hatch 4 of often opening on the nexine 1 on its wall, and middle level 2 outer wrapping are outer 3.This skin 3 is made by the enteric solubility material.No pain and very convenient is used in this utility model nonhazardous, and is non-stimulated to health, thus can be when sampling, make human body produce stress and influence the verity of sample.Because more than the intestinal juice sampler, some that make it not only can be used for patient are checked, and can be more widely used in the generaI investigation of normal population.For example it can be in the relation of various diseases and intestinal environment, particularly be applied in the research of the relation of forming with intestinal colony, also may be used for the research of the relation of cancer in digestive system and intestinal environment, and the research of extraordinary crowds' such as different places, race intestinal environment and healthy relation.Its appearance in a word will provide strong instrument to the research intestinal environment.It not only can be used for the people, is applicable to animal too, and its application prospect is quite wide.

Claims

1, intestinal juice sampler, it is one and the sizable hollow particle shape of oral medicine pill object, is made up of skin, middle level, nexine, and it is characterized in that: nexine is made by the hard inert material, the centre is that vacuum is hollow, layer wall be provided with one with hollow be connected often open thieff hatch; The middle level is made by whippy inert material, is provided with the slit facing to the thieff hatch of often opening on the nexine on its wall, and the middle level outer wrapping is the skin of being made up of the intestinal juice material.

2, intestinal sampler as claimed in claim 1 is characterized in that: it is shaped as ellipse garden shape.

3, intestinal sampler as claimed in claim 1, it is characterized in that: it is shaped as sphere.
