Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of experimental devices, in particular to a biochemical analyzer reaction cup cleaning device. Background Art
[0002] Hitachi's biochemical analyzer is an analytical instrument used in preventive medicine and public health. The contamination of the cuvette is closely related to the daily testing volume and test items performed by R&D operators. During routine maintenance, the cuvette is generally soaked in a 2% alkaline cleaning solution, then rinsed several times with pure water to remove any remaining cleaning solution, and any remaining water stains on the cuvette are wiped dry. The cotton swabs used during the cleaning process cannot clean the corners of the cuvette, and the wiping process can easily scratch the cuvette, affecting test accuracy. The subsequent drying process can also easily leave paper scraps, leading to large errors in the test.
[0003] Therefore, the existing ultrasonic cleaning process avoids the problem of stubborn residual reagents on the inner wall of the cup, which is difficult to clean, and saves labor costs. However, most reaction cups are rectangular and columnar in structure, with a single-side opening. When placed in an ultrasonic cleaning tank, they are prone to collision. At the same time, the cleaning liquid may not be poured into the reaction cup immediately, and bubbles may form inside the reaction cup, resulting in incomplete cleaning. Utility Model Content
[0004] The utility model aims to provide a biochemical analyzer reaction cup cleaning device, which utilizes an ultrasonic cleaning instrument and is equipped with a liftable bracket on the upper part, and the reaction cup is simply fixed to avoid the problems of bubbles and collisions inside the reaction cup.
[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0006] A biochemical analyzer cuvette cleaning device includes an ultrasonic cleaner, wherein support rods are supported at positions corresponding to corners on the upper side of the ultrasonic cleaner, and the upper ends of the support rods support a top plate, and a liftable column is installed in the center of the top plate, and the column corresponds to the center of the cleaning tank of the ultrasonic cleaner;
[0007] A support plate is installed at the lower end of the column for placing a reaction cup. The support plate has a hollow hole, a protective net is provided on the side of the support plate, a cover net is installed on the upper side of the support plate, and a first column sleeve is provided in the center of the cover net for socketing the column and telescoping to press the reaction cup.
[0008] Furthermore, a plurality of limiting bars are fixed on the upper side of the support plate. The limiting bars are evenly arranged around the column, and limiting grooves for accommodating reaction cups are formed between adjacent limiting bars.
[0009] The center of the support plate has a second column sleeve for limiting and sleeving the column body and enabling rotational fit.
[0010] Further, the side wall of the first column sleeve has a first screw sleeve, and a first locking knob is installed for fixing the first column sleeve after being tightened.
[0011] Further, the top plate has a third column sleeve for sleeving the column body. The side wall of the third column sleeve has a third screw sleeve, and a third locking knob is installed for fixing the column body after being locked.
[0012] Further, the top plate has an inner cavity and a blowing device is installed. A blowing groove for accommodating the support plate is formed on the lower side of the top plate, and air holes are formed on the side wall of the blowing groove.
[0013] The utility model has the following beneficial effects: Both the support plate and the cover net are circular. The side of the cover net is slightly larger than that of the support plate, which is used to perfectly cover the notch on the upper side of the support plate and hold against the reaction cup. Since the reaction cup is made of plastic, it is prone to floating after being placed in the cleaning solution and cannot be immersed in the cleaning solution immediately. After adding the cover net, it can not only initially fix the reaction cup, prevent collisions between them during the cleaning process, but also prevent floating.
[0014] The cleaning solution includes 2% alkaline cleaning solution / deionized water. First, soak and clean with 2% alkaline cleaning solution, and then wash with deionized water multiple times. After the cleaning is completed, lift the column body to separate the overall support plate from the cleaning tank, and the cleaning solution remaining in the reaction cup can flow out quickly, facilitating quick drainage. Description of the Drawings
[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for describing the embodiments will be briefly introduced below.
[0016] Figure 1 : Schematic structural diagram of the present utility model.
[0017] Figure 2 : Schematic structural diagram of the cooperation between the cover net and the support plate of the present utility model.
[0018] Figure 3 : Schematic structural diagram of the support plate of the present utility model.
[0019] In the drawings, the list of components represented by each reference numeral is as follows: ultrasonic cleaner 1, support rod 11, top plate 2, column body 3, support plate 4, reaction cup 7, protective net 5, cover net 6, first column sleeve 61, limiting strip 41, second column sleeve 42, first locking knob 62, third column sleeve 22, third locking knob 23, blowing groove 21. Detailed Embodiment
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] like Figure 1 As shown: A biochemical analyzer reaction cup cleaning device includes an ultrasonic cleaner 1, which is specifically a cubic structure with four corners. Support rods 11 are supported at the positions corresponding to the corners on the upper side of the ultrasonic cleaner 1. The upper ends of the support rods 11 support a top plate 2. A liftable column 3 is installed in the center of the top plate 2. The column 3 corresponds to the center of the cleaning tank of the ultrasonic cleaner 1; the upper end of the column is a driving device for driving the column to rise and fall.
[0022] A support plate 4 is mounted at the lower end of the column 3 for placing a reaction cup 7. The support plate 4 has a circular hollow hole. A protective net 5 is mounted on the side of the support plate 4. The support plate and the protective net form a bracket for placing the reaction cup. A cover net 6 is mounted on the upper side of the support plate 4. The center of the cover net 6 has a first column sleeve 61 for sleeved onto the column 3 and telescopically cooperating to press the reaction cup. The support plate and the cover net are both circular. The sides of the cover net are slightly larger than the sides of the support plate, which is used to perfectly cover the notch on the upper side of the support plate and to support the reaction cup. Since the reaction cup is made of plastic, it is prone to floating after being placed in the cleaning solution and cannot be immersed in the cleaning solution immediately. After adding the cover net, it can not only initially fix the reaction cup and prevent collisions during the cleaning process, but also prevent floating.
[0023] The cleaning solution includes 2% alkaline cleaning solution / deionized water. First, soak and clean with 2% alkaline cleaning solution, and then clean multiple times with deionized water. After cleaning, lift the column to separate the entire support plate from the cleaning tank. The cleaning solution remaining in the reaction cup can flow out quickly, making it easy to quickly control drying.
[0024] like Figures 2 - 3 As shown, multiple limiting bars 41 are fixed to the upper side of the support plate 4. The limiting bars 41 are evenly arranged around the column 3, and the adjacent limiting bars 41 form limiting grooves for accommodating the reaction cups 7. When placing the reaction cups, make sure the cup openings face outward and arrange them in a regular pattern. The limiting bars can separate the reaction cups, allowing the cleaning solution to quickly fill the cup body during immersion.
[0025] A second column sleeve 42 is located in the center of the support plate 4, which is used to positionally engage the column 3 and rotatably engage it. This allows for manual rotation of the support plate. After immersion in the cleaning solution, the support plate can be rotated, causing the reaction cup to be centrifuged, which helps to expel bubbles. After the reaction cup is released from the cleaning solution, the support rod can be rotated in the same way, and the centrifugal force quickly expel any residual cleaning solution from the reaction cup.
[0026] like Figure 1As shown: The side wall of the first column sleeve 61 has a first screw sleeve, and a first locking knob 62 is installed, which is used to fix the first column sleeve 61 after screwing tightly. It is used to determine and adjust the position of the cover net, and it is convenient to place and remove the reaction cup after fixing the cover net.
[0027] The top plate 2 has a third column sleeve 22 for sleeving the column body. The side wall of the third column sleeve 22 has a third screw sleeve, and a third locking knob 23 is installed, which is used to fix the column body 3 after locking. The top plate 2 has an inner cavity and a blowing device is installed. A blowing groove 21 for accommodating the support plate 4 is provided on the lower side of the top plate 2, and air holes are provided on the side wall of the blowing groove 21. The positions of the air holes exactly correspond to the protective net on the side wall of the support plate, and are used to blow air on the upper side of the support plate to accelerate drying.
[0028] These embodiments are selected and specifically described in this specification in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can well understand and utilize the present utility model.
