Detailed Description

The specific embodiments illustrated below are intended as descriptions of various configurations of the presently disclosed subject technology and are not intended to represent the only configurations in which the presently disclosed subject technology may be practiced. Specific embodiments include specific details for the purpose of providing a thorough understanding of the presently disclosed subject matter technology. It will be apparent, however, to one skilled in the art that the disclosed subject matter technology is not limited to the specific details shown herein and may be practiced without these specific details.

Gene detectors typically include a temperature control system that controls the temperature of the sample to be raised and lowered, and the temperature of the sample is cycled through a range, typically between 60 degrees celsius and 95 degrees celsius. The sample is typically placed in a reactor, typically a test tube 200, the test tube 200 being made of a transparent material. The gene detector also comprises an optical system, wherein the optical system inputs light rays to the reactor, the reactor outputs the light rays to the optical system after the light rays are reflected by a sample in the test tube 200, and the optical system analyzes the light rays output by the reactor to realize gene detection.

Because the gene testing apparatus can generally test a plurality of samples at the same time, that is, the gene testing apparatus can test genes of a plurality of samples at the same time, the gene testing apparatus generally comprises a placing frame, the placing frame is used for placing the test tube 200, and the temperature control system generally controls the temperature of the test tube 200 through the placing frame. Therefore, the structure of the placement chamber has a large impact on the performance of the gene detector, such as: the structure of the placing frame influences the light taking of the optical system of the gene detector. Generally, to improve the accuracy of gene detection, the optical system should capture more of the light output by the cuvette 200.

Referring to fig. 1, 2 and 3, a light transmitter includes a body 100, one end of the body 100 has a light receiving portion, the light receiving portion includes a second receiving portion 102 capable of changing a light transmitting direction, and the second receiving portion 102 receives light from a side of a light-transmitting medium.

The light-transmitting medium is typically a cuvette 200. The miniaturized gene detector has a small size, and the optical system generally receives light from the bottom surface of the cuvette 200, while the bottom surface of the cuvette 200 generally has a small area, so that the amount of light taken by the optical system is very limited. In addition, in consideration of the size of the gene testing apparatus, the number of optical system components of the gene testing apparatus should be reduced as much as possible to miniaturize the gene testing apparatus.

According to the scheme, the second receiving part 102 is used for receiving the light rays emitted by the side surface of the test tube 200, the light ray receiving area of the optical system is increased, and meanwhile, the second receiving part 102 has the capability of changing the light ray transmission direction, so that the optical system does not need to be additionally provided with a light ray guide structure, the size of the gene detector is reduced, and the manufacturing cost of the gene detector is reduced.

In some embodiments, the light receiving part further comprises a first receiving part (101), wherein the first receiving part 101 is recessed into the body 100, and the second receiving part 102 is protruded out of the body 100.

In practice, the light receiving portion generally receives the light reflected by the test tube 200, so that the more light the light receiving portion receives, the higher the detection accuracy of the gene detector. By increasing the area of the light receiving part for receiving the light, the light received by the light receiving part can be effectively increased.

In practical applications, the first receiving portion 101 generally receives the light reflected from the bottom of the test tube 200, and the second receiving portion 102 generally receives the light reflected from the side of the test tube 200. According to the scheme, the light reflected by the bottom and the side surface of the test tube 200 is received, so that the light received by the light receiving part is effectively increased, and the detection precision of the gene detector is improved.

Referring to fig. 1 to 3, in some embodiments, the body 100 is further provided with a light input portion 103. The body 100 may be integrated with the light input portion 103.

The light input portion 103 protrudes from the body 100.

The diameter of the light input part 103 is smaller than that of the first receiving part 101.

A part of the light input by the light input unit 103 is input to the light receiving medium by the first receiving unit 101.

The optical system of the gene detector generally includes a light source, which irradiates light from the light source into the test tube 200, then receives the light reflected from the test tube 200, and finally the optical system analyzes the light reflected from the test tube 200, so as to achieve the purpose of gene detection. Since the light source is required to input light into the cuvette 200, the interference of the light input into the cuvette 200 with the light reflected from the cuvette 200 should be minimized.

The interference of the light input by the light source to the light output by the cuvette 200 can be effectively reduced by making the diameter of the light input part 103 smaller than that of the first receiving part 101, and the accuracy of the gene detector is improved.

The optically transmissive medium is generally referred to as a cuvette 200, and the sample and reagents are stored in the cuvette 200.

Since the optical system includes a light source, the light source should be conveniently assembled with the light input part 103 to reduce the loss of light from the light source. The light input part 103 protrudes out of the body 100, so that the light input part can be conveniently assembled with a light source, and the performance of the light transmitter is optimized. For example, a connection sleeve may be provided on the light source, and then the light source may be sleeved on the light input portion 103.

Referring to fig. 1 to 3, in some embodiments, the first receiving portion 101 is shaped like a hemisphere. Typically, the bottom of the cuvette 200 has a hemispherical shape to facilitate processing of the cuvette 200. Therefore, the first receiving portion 101 is hemispherical, which is beneficial to the matching of the light transmitter and the test tube 200, and optimizes the performance of the light transmitter.

As shown in fig. 4, there are at least two second receiving parts 102, and the second receiving parts 102 are respectively located at two sides of the light-transmitted medium.

The second receiving portion 102 is mainly used for receiving the light reflected by the side surface of the test tube 200, and the number and specific shape of the second receiving portion 102 are not limited, and can be freely designed.

For example, when the first receiving portion 101 is a hemisphere, the body 100 may extend along an axis of the first receiving portion 101 to form the second receiving portion 102, and in this case, the second receiving portion 102 is cylindrical, and the first receiving portion 101 is located at one end of the second receiving portion 102.

In some embodiments, the body 100 is a solid structure with total reflection capability.

Alternatively, the body 100 is a hollow structure having a reflective layer on an inner wall of the body 100.

The body 100 is a hollow or solid structure, which can implement the technical solution of the present disclosure, and therefore, the specific structure of the body 100 is not limited, and can be freely designed. When the body 100 is a hollow structure, the reflective layer may be coated on the inner sidewall of the body 100.

As shown in fig. 5, the specific shape of the body 100 is not limited, and may be freely designed, for example, as shown in fig. 5, the body 100 may be made cylindrical, or the body 100 may be truncated pyramid shape with a wide top and a narrow bottom, or the body 100 may be truncated cone shape with a large top and a small bottom, and so on.
