Abstract
The invention discloses a reaction cup which comprises a cup body, wherein transparent detection surfaces are arranged on two opposite side surfaces of the cup body, and the detection surfaces are recessed towards the inner side of the cup body. Because the detection surface is lower than the outer surface of the cup body, when two reaction cups are stuck together, a gap is reserved between the detection surfaces of the two reaction cups, and the two reaction cups cannot rub against each other. Also, when the reaction cup is inserted into the corresponding hole on the detecting instrument, the detecting surface and the inner wall of the hole are not contacted, and are not rubbed with each other. Therefore, the detection surface is not scratched or polluted by friction.
Description
Technical Field
The invention relates to the technical field of inspection instruments, in particular to a reaction cup.
Background
The reaction cup is a common instrument applied to biological, chemical and medical detection. When the sample-taking device is used, the sampling head dipped with the sample is firstly inserted into the reaction cup, then the reagent is injected into the reagent cup, and then the reaction cup is swung to enable the sample to be fully mixed with the reagent. The cuvette is then placed in the instrument and the light from the light emitter of the instrument is transmitted through the cuvette (during which the light passes through the reagent mixed with the sample) and then impinges on the light receiver, where the sample is detected by analysis of the light received by the light receiver.
In actual operation, in order to improve work efficiency, generally once sample a plurality of samples, therefore the quantity that uses the reagent cup has a plurality ofly, and the reagent cup is concentrated in depositing and transporting the in-process, and adjacent reagent cup can not avoid bumping and friction, and in the locating hole on the instrument is put down to the reagent cup when detecting, the outer wall of reagent cup also rubs with the locating hole easily to lead to the surface of reagent cup to be scratched. If light passes through the scratched reagent cup and is received by the receiver, the accuracy of the detection result is affected.
In addition, the apparatus typically detects a row of reagent cups simultaneously, each of which corresponds to a pair of light emitters and light receivers. When the corresponding light emitter of one of the reagent cups irradiates the reagent cup, light easily enters the adjacent reagent cup from the side surface through refraction or reflection, so that detection of the adjacent reagent cup is interfered, and the detection result is affected.

Further, the cup body is in a quadrangular shape, the detection surfaces are respectively arranged on two opposite side surfaces of the cup body, and the grooves are respectively arranged on the other two opposite side surfaces of the cup body.
Further, the distance between the detection surface and the corresponding side surface of the cup body is 0.1-0.5mm.
Further, the bottom surface of the groove is arc-shaped, and the depth of the groove is 0.1-0.5mm.
Further, the cross section area of the bottom of the cup body is gradually increased from bottom to top.
The invention has the positive effects that:
1. The cup body is provided with the detection surface which is concave towards the inner side of the cup body, and because the detection surface is lower than the outer surface of the cup body, when two reaction cups are stuck together, a gap is reserved between the detection surfaces of the two reaction cups, and the two reaction cups cannot rub against each other. Also, when the reaction cup is inserted into the corresponding hole on the detecting instrument, the detecting surface and the inner wall of the hole are not contacted, and are not rubbed with each other. Therefore, the detection surface is not scratched or polluted by friction.
2. The outside of the cup body is also provided with a groove, when light passes through the cup body, a small amount of light is emitted to the groove and scattered and diffusely reflected by the groove, so that the influence on detection of adjacent reagent cups is greatly reduced, and the accuracy of instrument detection is ensured. Meanwhile, the grooves can increase friction force, so that the reaction cup is convenient to hold, and slipping is prevented.

Detailed Description
Example 1
As shown in fig. 1 to 6, a reaction cup comprises a quadrangular cup body 2, wherein a cup opening of the cup body 2 is positioned at the top. The cup body 2 is made of transparent materials (such as cycloolefin copolymer), the cup body 2 is provided with inwards concave detection surfaces 1 on two opposite side surfaces, the detection surfaces 1 are rectangular, the detection surfaces 1 are lower than the outer surface of the cup body 2 by 0.2mm, and the detection surfaces 1 are all positioned at the lower part of the cup body 2.
The two detection surfaces 1 are planes, and the two planes are parallel to each other.
Because the detection surface 1 is lower than the outer surface of the cup body 2, when two reaction cups are stuck together, a gap exists between the detection surfaces 1 of the two reaction cups, and the two reaction cups cannot rub against each other. Also, when the reaction cup is inserted into the corresponding hole on the detecting instrument, the detecting surface 1 and the inner wall of the hole are not contacted, and are not rubbed with each other. Therefore, the detection surface 1 is not scratched or contaminated by friction.
As shown in fig. 7, when the light emitted from the light emitter 7 passes through the left detection surface 1, the reagent mixed with the sample, and the right detection surface 1 in order, it is received by the light receiver 8 and then detected by the instrument.
Example 2
This embodiment differs from embodiment 1 in that:
The cup 2 is provided with stripe-shaped grooves 6 on the remaining to two opposite sides. The grooves 6 are vertical and are in a plurality of strips, the bottom surfaces of the grooves 6 are arc-shaped, and the depth of the grooves 6 is 0.2mm.
When light passes through the cup body 2, a small amount of light irradiates the groove 6 and is scattered and diffusely reflected by the groove 6, so that the influence on detection of adjacent reagent cups is greatly reduced, and the accuracy of instrument detection is ensured. Meanwhile, the grooves can increase friction force, so that the reaction cup is convenient to hold, and slipping is prevented.
Example 3
This embodiment differs from embodiment 2 in that:
The cup body 2 is provided with an annular flange 3 along the periphery of the cup mouth for enabling the reagent cup holder to be in a corresponding hole on the instrument.
Two vertical positioning ribs 4 are fixedly arranged on each side face, corresponding to the grooves 6, of the cup body 2, and the positioning ribs 4 are located on the upper portion of the cup body 1. The positioning ribs 4 are matched with grooves in holes on the instrument and are used for positioning the cup body 2.
The bottom of the positioning rib 4 is provided with a chamfer 5, which plays a guiding role, so that the reaction cup is more convenient to put into a hole on an instrument.
The bottom of the cup body 2 is high in the middle and low in the edge, and the edges of the bottom of the cup body 2 are located on the same plane. When the reaction cup is placed on a table top or an instrument, the reaction cup is more stable and is not easy to shake because only the annular edge of the bottom of the cup body 2 is in contact with the table top or the instrument.
The cross section of the bottom of the cup body 2 is in an inverted trapezoid shape, so that the cross section area of the bottom of the cup body 2 is gradually increased from bottom to top.
After the same volume of reagent is filled in the cup body 2, the cross section area of the bottom of the cup body 2 is gradually increased from bottom to top, so that compared with the cup body 2 with the same cross section area, the cup body 2 can obtain higher liquid level height, and the influence of impurities at the bottom of the cup body 2 on the detection result can be reduced or the detection can be more conveniently carried out.
