Description

Technical Field

[0001] This invention relates to the field of medical testing technology, and in particular to a testing kit. Background Technology

[0002] In medical testing, test samples are often stored in reagent bottles and then transported to the testing center for testing. When taking samples from reagent bottles, they are usually stored in test kits.

[0003] For example, application number CN201920655790.5 relates to the field of packaging technology and discloses a test kit, including a box body. A lid is hinged to the upper side wall of the box body. A shelf is fixedly connected to the bottom of the box body. Multiple placement slots are provided on the upper side wall of the shelf. A storage mechanism is connected inside the box body. A locking mechanism connects the box body and the lid. A lifting mechanism is connected to the upper side of the lid. This utility model effectively improves the ease of use of the test kit, allowing for quick opening and closing of the lid, thus improving the operational convenience of the test kit. However, existing test kits require the reagent bottles to be removed from the kit before use. After sampling, the bottles are put back into the kit. This repetitive process can easily lead to mistakes. Furthermore, when there are many reagent bottles in the kit, it is difficult to pick them up. Other bottles need to be moved around to make it easier to pick up the desired one, which is cumbersome. Summary of the Invention

The ejector driven bevel gear is coaxially and fixedly connected to the front end face of the ejector rotating shaft. The ejector driving bevel gear and the ejector driven bevel gear mesh together to form a bevel gear transmission mechanism.

[0008] Furthermore, the ejection transmission mechanism includes: An ejector eccentric wheel is eccentrically and fixedly connected to the shaft of the ejector rotating shaft; An ejector slider is slidably connected to the inside of the outer housing, and a cam structure is formed between the ejector slider and the ejector eccentric wheel; The ejector post is fixedly connected to the top of the ejector sliding member and is located directly below the detection and removal cover.

[0009] Furthermore, the shifting chain also includes a blocking plate, which is fixedly connected to the bottom of one set of lifting circular rails.

[0010] Furthermore, the automatic switching mechanism includes: A displacement drive sprocket is coaxially and fixedly connected to the bottom of the detection and retrieval cover; The shift driven sprocket is rotatably connected inside the outer housing.

[0015] This invention enables automatic ejection of test reagent tubes, facilitating their retrieval and automatic repositioning. It also allows for a one-to-one placement and retrieval operation, effectively preventing misplacement or incorrect retrieval. This makes it more convenient and simpler to use, provides a reminder function, and effectively avoids repeated retrieval. It is simple to operate and easy to use.

[0016] Furthermore, the reagent kit is placed in the reagent tube holder, and the detection and retrieval cover is rotated. The rotation of the detection and retrieval cover is driven by a bevel gear transmission mechanism consisting of a driving bevel gear and a driven bevel gear. The ejection shaft rotates through a cam structure consisting of an ejection slider and an ejection eccentric wheel, which in turn drives the ejection slider to slide up and down. The ejection slider pushes the corresponding test reagent tube upward through the ejection column, exposing the top of the test reagent tube for easy retrieval. The detection and retrieval cover is opened simultaneously with the automatic ejection of the test reagent tube, making it convenient and easy to use.

[0017] Furthermore, when the detection and retrieval cover is released, it springs back under the action of the return torsion spring. The detection and retrieval cover drives the shift driven sprocket to rotate through a transmission chain mechanism composed of a shift driving sprocket and a shift driven sprocket. The detection and retrieval cover drives the shift clutch shaft to rotate through a ratchet mechanism. The shift clutch shaft drives the shift automatic shaft to rotate through the shift end face teeth. The shift automatic shaft drives the shift chain to rotate through a chain transmission mechanism, thereby realizing the shifting of the reagent tube rack. After the test reagent tubes have been sampled, they can be placed into the reagent tube rack through the placement port. This can realize the automatic shifting of the test reagent tubes and realize a one-to-one operation mode, which can effectively avoid misplacement or misrepresentation, making it more convenient and simpler to use.

[0018] In addition, when all the test kits are used up, the baffle plate rotates to the bottom of the test kit cover. At this time, when the test kit cover is rotated, the ejector pin blocks the bottom of the baffle plate, preventing the test kit cover from rotating. This indicates to medical staff that all the test kits have been used up, effectively avoiding the need for duplicate test kit sampling and improving ease of use.

[0019] Furthermore, when removing test tubes for testing or resetting the test kit, loosen the locking nut and move it. The locking nut causes the clutch sliding seat to slide to the right. The clutch sliding seat, through the planar cam structure formed by the clutch guide post and the clutch guide groove, causes the clutch lifting seat to slide downward. The clutch lifting seat causes the shifting clutch shaft to slide downward, and the shifting end face teeth disengage from the shifting automatic shaft. At this time, the operating handle can be rotated freely. The shifting manual shaft drives the shifting chain to rotate through the chain transmission mechanism, realizing the shifting of the test tube holder. Test tubes can be freely placed and removed through the placement port. Take out the test tubes from the test kit and then put in empty test tubes. This facilitates the reuse of the test kit. The operation is simple and convenient. Attached Figure Description
