It can be seen that biological detection devices are an important tool in the detection process.

[0003] However, the existing biological detection devices only include one detection accuracy. If a detection method with different accuracy is required, the parts of each biological detection device cannot be used. It is necessary to replace the accessories in the biological detection device.

DETAILED DESCRIPTION

[0027] The following will be combined with the attached Figure 1 To Attachment Figure 6 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be noted that if there are directions involved in the embodiments of the present invention, they shall be based on the directions shown in the drawings, such as front and rear. Figure 1 The specific Figure 1 The left side is the front, Figure 1 The right side is the back; at the same time Figure 1 As shown in the figure, the left-right direction is roughly the horizontal direction, and the up-down direction shown in the figure is the vertical direction. If a certain posture changes, the directional indication will also change accordingly.

[0029] Existing biological detection equipment usually has only one detection accuracy. When multiple different detection accuracy levels are required for microorganisms, biological detection equipment with only one detection accuracy can no longer meet the needs of inspectors. Therefore, manufacturers need to spend more on material costs and assembly costs to manufacture the equipment, which is inconvenient to operate and wastes materials.

[0030] In this regard, Figure 1 As shown, the inventor provides a biological detection connector for connecting a reagent tube 2 to be detected and a detection module 3 to guide the substance in the reagent tube 2 to be detected to the detection module 3. The biological detection connector includes a main body 1, which has a channel 11, and one end of the channel 11 has an inlet 111 connected to the outside world. The main body 1 has two independent output channels 12, and the two independent output channels 12 are connected to the channel 11 and make the channel 11 pass through the outside world.

[0031] It should be understood that, firstly, a biological detection connector adopting this design has two independent output channels 12 corresponding to different detection modules 3. When in use, each different detection module 3 corresponds to a detection accuracy, and when the substance in the reagent tube 2 to be detected is guided to different detection modules 3 for detection, a detection data that meets the corresponding accuracy of the detection module 3 is obtained.

[0032] Secondly, since the biological detection connector includes a plurality of different output channels 12 corresponding to different detection modules 3, when the biological detection connector is assembled in the aerosol detection equipment, it is not necessary to assemble a plurality of different precision detection devices to achieve different precision detection requirements for different microorganisms. Specifically, when in use, the purchasing personnel only need to report the precision standard to be tested to the manufacturer in advance, and the manufacturer will assemble and connect one side of the output channel 12 with the corresponding precision on the biological detection connector with the corresponding detection module 3 according to the purchasing requirements, which overcomes the technical problem that it is time-consuming and material-consuming for manufacturers to produce different detection connectors corresponding to different detection accuracies. Therefore, this technical solution achieves the purpose of saving materials for manufacturers when producing equipment.

[0033] Further, such as Figure 2 and Figure 4 As shown, the axial included angle between the two output channels 12 is α, which is less than 180°.

[0034] It should be noted that, in this embodiment, the different detection modules 3 are located on the left side of the detection body 1 , which is of course not limited to the left side, but may also be on the right side or any side, as long as the different detection modules 3 are located on the same side of the detection body 1 .

[0035] Since the different detection modules 3 are located on the same side of the detection body 1, the axial directions of the two output channels 12 need to have a certain angle a, and the angle a needs to be less than 180° to correspond to the different detection modules 3. Specifically, when different detection accuracies need to be adjusted during assembly, it is only necessary to adjust the corresponding direction of the output channel 12 of the corresponding accuracy of the connector relative to the detection module 3, and then start the detection module of the corresponding accuracy in the detection module 3. It should be understood that if the independent output channels 12 are located on the same side, it is impossible to flexibly achieve corresponding assembly with the detection module 3.

[0036] In order to further facilitate the assembly of the biological detection connector and the detection module 3, preferably, the angle a is 90°.

[0037] like Figure 4As shown, when the angle a is 90°, when installing the biological detection connector, it is only necessary to rotate the biological detection connector in a direction of 90° so that the output channel 12 corresponds to the detection module 3. The 90° rotation operation conforms to the assembly habits of the assembler, and can also distinguish the direction well, making installation easy.

[0038] Furthermore, in order to make the biological detection connector and the detection module 3 more securely assembled and avoid the biological detection connector from moving relative to the detection module 3 during assembly, the output channel 12 has a stepped hole 13 at the place where it contacts and connects with the detection module 3. The stepped hole 13 is in a stepped shape that is larger on the outside and smaller on the inside, so that the stepped hole 13 can abut the assembly end of the detection module 3 against the step of the stepped hole 13 to prevent the biological detection connector from moving relative to the detection module 3, thereby making the corresponding assembly more secure.

[0039] In addition, the stepped channel 13 is designed to be large on the outside and small on the inside, which enables the assembly end of the detection module 3 to abut against the step, so that the connection between the detection module 3 and the output channel 12 is sealed, thereby preventing light leakage when the detection module 3 detects the substance to be detected in the reagent tube 2 to ensure the smooth execution of the detection.

[0040] In another embodiment, the stepped channel 13 is in the shape of a square hole or a round hole, as long as the shape of the stepped channel 13 facilitates the detection module 3 to detect the reagent tube 2 to be detected assembled in the channel 11 .

[0041] Further, such as Figure 3 As shown, each output channel 11 has an assembly structure 14 on its circumference for assembly with the detection module 3. The assembly structure 13 is four threaded holes 141 evenly distributed on the circumference of the output channel.

[0042] It should be understood that by combining the threaded hole 141 with a corresponding assembly part on the detection module 3 , such as a screw, etc., the biological detection connector is fixedly assembled and connected to the detection module 3 .

[0043] Furthermore, the outer surface portion of the body 1 located in the vicinity of the output hole 13 end of each output channel 12 is a plane.

[0044] The design is such that the plane is closely fitted with the contact surface of the detection module 3, so as to form a closed detection channel between the detection module 3 and the output hole 13. In cooperation with the step on the output hole 13 mentioned above, the detection module 3 is abutted against the step through its assembly end, and the end of the detection module 3 is partially in contact with the outer surface of the area near the output hole 13. Under the design of such a double sealing structure, it is possible to prevent the detection module 3 from leaking light during the detection process to affect the detection accuracy of the object to be detected in the reagent tube 2 to be detected.

[0045] Further, such as Figure 4 As shown, the two output channels 12 are transversely arranged in the body 1 and communicate with the side of the channel 11. Along the axial direction of the channel 11, the opening 112 is located at the upper end of the channel 11, so that the channel 11 communicates with the open area 113; the two output channels 12 are located at the lower part.

[0046] It should be understood that the opening 112 is used to place the reagent tube 2 to be detected, and the reagent tube 2 to be detected enters the lower part of the channel 11 along the opening 112. The detection component in the detection module 3 can irradiate the reagent tube 2 to be detected placed in the channel 11 through the output hole 13 to detect the substance in the reagent tube 2 to be detected.

[0047] It should be noted that, when specifically assembled, the periphery of the output channel 12 is also provided with a sealing plate 17 capable of sealing it, and the sealing plate 17 is detachably assembled on the periphery of the output channel 12. When one of the output channels 12 is required for detection, the other output channel 12 needs to be sealed with the sealing plate 17 to avoid inaccurate detection of the substance to be detected in the reagent tube 2 to be detected due to light leakage during detection.

[0048] Further, such as Figure 5 As shown, the detection body 1 has a first assembly portion 114 for assembling the biological detection connector with the detection body 1 on one side of the opening of the channel 11. The first assembly portion 114 is connected to the entrance 111 of the channel 11, and extends outward from the entrance 111 to form an outer flange portion 1144. During assembly, the outer flange portion 1144 abuts against the assembly portion of the detection body 1, so that the biological detection connector is firmly assembled in the detection body 1.

[0049] Further, such as Figure 6As shown, fixing parts 1145 can also be provided on both sides below the outer flange part 1144, and the fixing parts 1145 are assembled and connected with the detection body 1, so that the connection between the biological detection connector and the detection body 1 can be more secure and stable, and can further prevent the connection between the biological detection connector and the detection body 1 from loosening during the insertion and removal of the tube 4 to be detected when the tube 4 to be detected is assembled on the biological detection connector.

[0050] Further as Figure 5 As shown, the first assembly portion 114 also includes an inner flange portion 1141, and buckles 1142 are respectively provided on both sides of the outer periphery of the inner flange portion 1141. The center point of the inner diameter of the inner flange portion 1141 has a hole groove 1143, and the hole groove 1143 is connected to the opening 112 of the channel 11. It should be understood that in this embodiment, the hole groove 1143 is coaxially arranged with the channel 11.

[0051] Specifically, when in use, the protruding pieces 41 (not shown in the figure) at both ends of the tube to be tested 4 containing the reagent tube to be tested 2 are buckled into the buckles 1142, and the bottom end surface of the tube to be tested 4 abuts against the inner side of the inner flange portion 1141, so that the bottom outer wall of the tube to be tested 4 abuts against the side wall of the inner flange portion 1141, so that the tube to be tested 4 can be firmly assembled in the open area 113 of the channel 11.

[0052] When the tube to be tested 4 is firmly assembled in the open area 113 of the channel 11, the reagent tube 2 to be tested in the tube to be tested 4 enters the interior of the channel 11 from the opening 112 of the channel 11 through the hole groove 1143, and is then tested by the testing module 3 through the output channel 12. It should be noted that the assembly of the tube to be tested 4 relative to the open area 113 can be replaced according to actual needs, for example, it can be replaced with a long tube to be tested 4 or a short tube to be tested 4.

[0053] Further, such as Figure 6 As shown, a second assembly portion 15 is on the same plane as one of the output channels 12 and extends from the lower end of the output channel 12, and threaded holes are provided at four corners of one side of the second assembly portion 15, and the threaded holes are used to connect with the detection body 1, so that the biological detection connector can be more firmly assembled in the detection body 1, avoiding the loosening of the connection between the biological detection connector and the detection body 1 during the frequent buckling process of the biological detection connector on the tube 4 to be detected.

[0054] Preferably, the second assembly portion 15 is a plate-like structure. It should be understood that the plate-like structure can increase the fixed contact area between the biological detection connector and the detection body 1, making the contact between the biological detection connector and the detection body 1 more stable.

[0055] A biological detector includes a detector body, the detector body has a reagent tube 2 to be detected and a detection module 3, and the reagent tube 2 to be detected and the detection module 3 are connected to each other through a biological detection connector introduced in this scheme. Specifically, the reagent tube 2 to be detected is assembled in the tube 4 to be detected, and the tube 4 to be detected is assembled in the open area 113 of the biological detection connector. After assembly, the reagent tube 2 to be detected in the tube 4 to be detected is placed in the channel 11 until it contacts the bottom of the channel 11, and is irradiated and detected by the detection module 3 through the independent output channel 12 connected to the channel 11.

[0056] Preferably, as one of the optional embodiments of the present case, a biological detection connector of the present technical solution is arranged on a side of the detector body.

[0057] Through this design, a sampling device is provided on the left side of the detector body. When in use, the R&D personnel can collect samples on the left side of the detector and then send the samples to the right side of the detector for testing to save the transportation time of the samples. The structural design of this detector is reasonable and easy to operate. It can also use a variety of different detection accuracies. As long as the output channel 12 of the biological detection connector corresponding to a certain detection accuracy is set correspondingly with the detection module 3, a detector with the corresponding detection accuracy can be obtained. This overcomes the previous technical problems that one detector can only be equipped with one detection accuracy. When a different detection accuracy is required, the detector is not applicable, and when it leaves the factory, the parts of the detectors with different accuracies are not applicable. Such large and complex parts require a lot of human management costs, material costs, and assembly time costs.

[0058] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
