Description

stool tester

technical field

The present invention relates to a stool tester, which is a device for collecting stools and biological samples for biomicroscopy.

Background technique

At present, the stool tester used in the hospital is used for dyeing with MIF (merthiolate-iodineformalin), ether and other test reagents, such as the new application for "specimen collector" in Taiwan Patent Application No. In the process of dripping the sample into the test tube after the interaction between the sample and the test reagent, because there is no joint and fixed between the bottle and the test tube, and the size is different, it cannot be properly placed on the fixing frame, so both hands are required to fix it to the bottle. The solution in the body is completely dripped into the test tube. Therefore, when a large number of samples are to be tested, a lot of manpower and time must be spent, which is quite inefficient.

In addition, if it is not certain that the solution in the bottle is completely dripped into the test tube, if there is still solution in the bottle and the solution is removed, it will cause the residual solution to drip out and cause a pungent odor in the working environment. Centrifuge the solution after dripping. After the test tube, the supernatant needs to be poured out in advance, and the bottom part to be tested is retained. Since a considerable amount of irritating odor will still be inhaled during the pouring out of the supernatant, the supernatant will cause discomfort to the operator, and a large amount of The liquid pouring out of the organic solution requires a lot of clean water to clean the water tank, and it takes a lot of money to treat the sewage, and the liquid is easy to get wet when pouring out the liquid, and at the same time, the small substances in the solution sample will be mixed with the supernatant, which will be diluted and affect the concentration. disadvantages.

In view of the above shortcomings, the inventor believes that it is necessary to urgently need to be corrected, and based on his years of experience in the design and manufacture of related products, as well as his consistently good design concepts, he has researched and created the above disadvantages. After continuous efforts, the stool tester of the present invention is finally launched, which improves the efficacy of the product by correcting the excellent product structure.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a feces tester, which has a simple structure, is easy to operate, can provide better sealing, does not need to pour out the supernatant during operation, and will not expose the smell of feces and organic solutions to the air, It will not touch the hands, which can effectively protect the health of medical examiners. In addition, it improves the traditional method of taking samples with a dropper, and improves the structure of taking samples.

In order to achieve the aforementioned purpose, the present invention discloses a stool tester, which is characterized by comprising:

A collection group, the collection group includes a collection container, a collection chamber, a joint cover, a toilet access piece, a filter screen, a through hole and a diaphragm, the collection container has the collection room inside, and the top cover of the collection room is provided with the joint cover, The joint cover is used to assemble the toilet access piece, and the filter screen is installed near the bottom of the collection chamber, and the through hole is opened at the bottom of the collection container relative to the collection chamber, and the diaphragm is formed from the outside is sealed on the through hole, and an inner constriction is concave at the bottom of the outer periphery of the collection container;

An inspection group, the inspection group includes an inspection container, an inspection chamber, an outlet, a funnel, a gasket, an extrusion device and a bottom cover, the inspection container can be received by the inner neck, the inspection container has the inspection chamber inside, and the inspection chamber is located in the inspection container. The inspection container is provided with the outlet at the bottom of the inspection chamber, and the funnel and the gasket are sequentially installed in the inspection chamber above the outlet, so that there is a fixed volume between the funnel and the outlet in the inspection chamber, and the The extrusion device is installed outside the outlet. The extrusion device has an outer sleeve. The outer sleeve is fixed on the outer end of the outlet. A blocking post is installed in the outer sleeve. One end of the blocking post protrudes to the outer sleeve. There is a stopper on the stopper, and an elastic body is installed between the stopper and the outer end of the outlet, the elastic body is used to abut the stopper to block the outer sleeve, the bottom The lid is used to cover the bottom of the inspection container to close the outlet and the extrusion device.

Wherein, the corresponding positions of the toilet taking piece of the collection group and the joint cover are respectively provided with threads that can be screwed together with each other.

Among them, the funnel of the test group was in the shape of an inverted cone like a fish cage to avoid the backflow of the tested substance after centrifugation to the supernatant.

Therefore, the test group of the stool tester of the present invention flows out or blocks the solution to be microscopically inspected through the extrusion device, and does not need to pour out the supernatant or use a dropper, so the solution to be microscopically inspected is taken out after It is more convenient and hygienic, and the overall operation efficiency is greatly improved. In addition, the collection group has a tail cover, and the inspection group has a bottom cover, so it can avoid the pollution caused by the outflow of organic solution during use, and there is no need for inhalation stimulation during operation. Smell, is odorless and tasteless low pollution tester.

In addition, the funnel and gasket set in the inspection group can make a fixed volume of small substances in the inspection chamber between the corresponding funnel and the outlet of the inspection chamber, and avoid mixing with the supernatant in the inspection chamber during extrusion, thereby preventing the observed The concentration of fine substances in the test body is diluted, which also enhances the practical efficacy of the product.
