Abstract
The utility model relates to a suction-ear type colorimetric utensil, comprising an upper shell, a lower shell and a button-type gasbag. The button-type gasbag, the upper shell and the lower shell are buckled to form a suction-ear type body; the fore part of the body is provided with a slender flat cuboid which is formed by the upper shell and the lower shell and has a liquid channel arranged in the middle; a colorimetric measurement holding cavity is arranged in the liquid channel; the button-type gasbag is arranged on the upper shell at a closed end of the suction-ear type body and is communicated with the liquid channel; the button-type gasbag is a hemispherical extrusion-type elastic gasbag. When the button-type gasbag is pressed down, liquid samples can be sucked into the colorimetric measurement holding cavity for photometric detection by use of the elasticity of the gasbag. The colorimetric utensil is simple in structure, easy to process, simple and convenient to suck in to-be-detected liquid and little in the consumption of the liquid samples; because of utilizing an optical detection device to carry out the optical detection of liquid composition and concentration, the colorimetric utensil is practical, low in cost and convenient to use.
Description
Technical field
The utility model relates to a kind of cuvette of fluid sample optical detection, and specifically a kind of air bag is inhaled ear formula cuvette.
Background technology
We know that the mensuration of haemoglobin is one of project of blood routine detection.In blood source examination the inside is one of project of necessary check.Haemoglobin is erythrocytic principal ingredient.Its function be in lung in conjunction with oxygen, deliver to whole body each the tissue and will organize in carbon dioxide deliver to lung and breathe out external.Because red blood cell and haemoglobin have substantial connection, so their clinical meaning is basic identical.Haemoglobin can reflect severity of anemia better.Adopting optical detection to differentiate material is technological means commonly used during microcosmic detects.At present, be earlier testing liquid to be placed cup in the optical detective technology scheme, carry out optical detection by optical detection apparatus again, judge substance classes and concentration at last.Above-mentioned the deficiencies in the prior art are that required fluid sample is many, and detecting with container is not disposable use, manually clean, and troublesome poeration also causes personal error easily.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, and processes simple and easyly, and the fluid sample consumption is few, the gasbag-type cuvette practical, that cost is low, easy to use.
The technical scheme in the invention for solving the above technical problem is: a kind of suction ear formula cuvette, it is characterized in that: it comprises upper shell, lower house and a push button air bag, push button air bag, upper shell, lower house fasten to form inhales ear formula main body, its front portion is the elongated dull and stereotyped rectangular parallelepiped of the middle carrying liqs passage of upper shell, lower house composition, be provided with a colorimetric measurement cavity volume in the fluid passage, the push button air bag is installed on the upper shell of inhaling ear formula main body blind end, is connected with fluid passage.
The said push button air bag of the utility model is a hemisphere squash type elastic bag.Depress this push button air bag, utilize air bag elasticity, can in cavity volume and fluid passage, produce negative pressure, fluid sample is sucked in the colorimetric measurement cavity volume.Corresponding upper shell, the lower house inside and outside wall in said colorimetric measurement cavity volume zone is transparent bright and clean plane.One end upper shell of elongated dull and stereotyped rectangular parallelepiped opening is provided with the semicircle suction inlet of an indent.
The utility model is owing to adopt the push button air bag, and itself and upper shell, lower house fasten to form inhales ear formula main body, utilizes air bag elasticity that fluid sample is sucked and carries out photometric detection in the colorimetric measurement zone.Against existing technologies, the utility model simple structure is processed simple and easy, it is simple and convenient to suck liquid to be detected, and the fluid sample consumption is few, and it utilizes optical detection apparatus to carry out liquid component and concentration optical detection, practical, cost is low, easy to use, is a kind of desirable cuvette.Be particularly suitable for the detection of the unknown concentration sample that concentration is higher and variation range is very wide, as the detection of haemoglobin in the blood constituent.Also can satisfy the detection of the fluid sample of the low or low concentration of absorbance.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to synoptic diagram.
1. upper shells among the figure, 2. lower house, 3. push button air bag, 4. fluid passage, 5. colorimetric measurement cavity volume, 6. suction inlet.
Embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of suction ear formula cuvette, it comprises upper shell 1, lower house 2 and a push button air bag 3 etc.Push button air bag 3, upper shell 1, lower house 2 fasten to form inhales ear formula main body, and push button air bag 3 is installed on the upper shell of inhaling ear formula main body blind end.Its front portion is the elongated dull and stereotyped rectangular parallelepiped of the middle carrying liqs passage 4 of upper shell 1, lower house 2 compositions, is provided with colorimetric measurement cavity volume 5 in the fluid passage 4.Push button air bag 3 is connected with fluid passage 4 in the elongated dull and stereotyped rectangular parallelepiped.
The said push button air bag 3 of the utility model is a hemisphere squash type elastic bag.Depress this push button air bag, utilize air bag elasticity, can in cavity volume and fluid passage, produce negative pressure, fluid sample is sucked in the colorimetric measurement cavity volume 5.
Corresponding upper shell, the lower house inside and outside wall in the utility model said colorimetric measurement cavity volume 5 zones is transparent bright and clean plane.Flat upper shell, lower house can be by transparent bright and clean materials processings, and its material can be organic glass, epoxy resin etc.
One end upper shell of the elongated dull and stereotyped rectangular parallelepiped opening of the utility model is provided with the semicircle fluid intake 6 of an indent.During use, pressing button formula air bag 3 is aimed at a small amount of liquid to be detected with the semicircle fluid intake 6 of indent, like this, utilizes air bag elasticity, can easily liquid to be detected be drawn into and carry out photometric detection in the colorimetric measurement zone.
The utility model simple structure is processed simple and easyly, and it is simple and convenient to suck liquid to be detected, and the fluid sample consumption is few, and it utilizes optical detection apparatus to carry out liquid component and concentration optical detection, and is practical, cost is low, easy to use.Be suitable for the detection of the unknown concentration sample that concentration is higher and variation range is very wide, also can satisfy the detection of the fluid sample of the low or low concentration of absorbance.Detection as haemoglobin in the blood constituent.
