Abstract

The utility model discloses a gastric juice sampler which is used for the gastric juice extracting and assay in extensive crowd gastropathy tests. The utility model is composed of two metal thin wall casings with a hemispherical shape, a sheet elastic ring, and a medical sponge; the sphere ends of the two metal thin wall casings with a hemispherical shape are distributed with three small holes whose diameters are 2 mm; the bottom part of the metal thin wall casings with a hemispherical shape are respectively placed with a PH test paper and an occult blood test paper; the sheet elastic ring is a cylindrical through hole, and the length of one side opening of the sheet elastic ring is 3 mm; the materials are all white alloy, the use is convenient, and accurate gastric juice can be acquired; the utility model has great use value, particularly for gastric juice assay danger crowd in extensive crowd gastropathy tests and initial screening, the utility model can be used for multiple times after being sterilized, and the cost is low.

Description

Gastric juice sampler

This utility model belongs to a kind of large tracts of land crowd's gastropathy generaI investigation and extracts the gastric juice drawing device that the gastric juice chemical examination is used.

China hospital gastric juice extracts two kinds of methods is arranged at present: a kind of for stomach tube under the per nasal directly extracts gastric juice, patient is very painful; Another kind is a capsule sponge ball collector, though easy to operate, be fit to large tracts of land generaI investigation usefulness, the capsule of containing sponge dissolves at gastric, and sponge exposes, and is partly dissolved thing and adheres to sponge, influences the water absorption of sponge and the accuracy of the gastric juice composition got; Exposed sponge is being pulled out in the process through cardia, esophagus, pharynx and oral cavity route, and secretions, saliva, exfoliative cyte mix, and influence gastric juice determining result's accuracy, and disposable use economic cost is higher.

The purpose of this utility model provides in a kind of hemispherical metal thin-wall shell medical sponge, PH reagent paper, occult blood reagent paper and other test material is housed, its smooth surface can directly be brought the gastric lower position into and be contacted closely with gastric juice, utilize sponge fully to draw gastric juice, can obtain accurate testing result, and the reused gastric juice drawing device in sterile-processed back.

This utility model is by hemispherical metal thin-wall shell 1,4, thin slice elastic ring 3 and medical sponge are formed, the bottom of hemispherical metal thin-wall shell 1 is placed with a fritter PH reagent paper 7, the bottom of hemispherical metal thin-wall shell 4 is placed with a fritter occult blood reagent paper 6, be characterized in: the aperture 8 that uniform three diameters of the spheroid end of hemispherical metal thin-wall shell 1,4 are 2mm, its material is a bidery metal; Thin slice elastic ring 3 is a garden cylindricality through hole, and one side opening 9 is wide to be 3mm, and material is a bidery metal.

This utility model is easy to use, can obtain gastric juice accurately, particularly gets the gastric juice chemical examination among the large tracts of land crowd gastropathy generaI investigation primary dcreening operation population at risk and looks into the high-risk group very big use value is arranged, and can repeatedly use after sterile-processed, and cost is low.

Fig. 2 is this utility model left view;

Fig. 3 is the front view of this utility model thin slice elastic ring 3;

Fig. 4 is the side view of this utility model thin slice elastic ring 3.

In Fig. 1,2,3,4, hemispherical metal thin-wall shell 1,4 materials are all used bidery metal, the aperture 8 that uniform three diameters of its spheroid end are 2mm, its effect be make gastric juice by and wear draught line; Thin slice elastic ring 3 materials are bidery metal, and its opening 9 is 3mm, and effect is fixing hemispherical metal thin-wall shell 1,4, make them involutory stable.During assembling a fritter PH reagent paper 7 is put in hemispherical metal thin-wall shell 1 bottom, then thin slice elastic ring 3 is packed in the hemispherical metal thin-wall shell 1, inner chamber is equipped with medical sponge 2, again a fritter occult blood reagent paper 6 is put in hemispherical metal thin-wall shell 4 bottoms, its inwall is inserted on the outer wall of thin slice elastic ring 3, at last with pommel aperture 8 aligned positions of hemispherical metal thin-wall shell 1,4, medical No. 10 silk threads 5 are penetrated aperture 8 respectively to be fastened, stay the silk thread 5 of an about 40cm to make traction usefulness, pull out the gastric juice drawing device in order to per os.

Claims

A kind of gastric juice drawing device is by hemispherical metal thin-wall shell (1), (4), thin slice elastic ring (3) and medical sponge (2) are formed, be placed with a fritter PH reagent paper (7) in hemispherical metal thin-wall shell (1) bottom, be placed with a fritter occult blood reagent paper (6) in hemispherical metal thin-wall shell (4) bottom, it is characterized in that:

The aperture (8) that a, hemispherical metal thin-wall shell (1), uniform three diameters of (4) spheroid end are 2mm, material is a bidery metal;

B, thin slice elastic ring (3) are garden cylindricality through hole, and one side opening 9 is wide to be 3mm, and material is a bidery metal.
