Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow cytometer auxiliary equipment technology, specifically a self-cleaning and drying mechanism for the detection head of a flow cytometer. Background Technology
[0002] Flow cytometers use lasers as a light source to illuminate cells stained with specific fluorescence, generating scattered light and fluorescence signals. These signals are converted into electronic signals, analyzed by a computer, and written into a standard format data file. The flow cytometer's detection head is mainly responsible for receiving and detecting the scattered light and fluorescence signals generated by cells after laser irradiation. After use, the flow cytometer's detection head needs to be cleaned in preparation for the next test.
[0003] A search revealed that patent application number 202420355883.7 discloses a flow cytometer laser collimation calibration device, comprising a flow cytometer body, a detection groove carved in the middle of the front surface of the flow cytometer body, electrically driven adjustment mechanisms symmetrically arranged in the detection groove, a lifting plate arranged between the electrically driven adjustment mechanisms, a circular opening carved in the middle of the top surface of the lifting plate, a support mechanism arranged in the circular opening, a driving mechanism arranged at the bottom of the support mechanism, and a sample tube and a liquid storage tube respectively connected by multiple mounting rings in the support mechanism, with a cleaning mechanism arranged on the inner wall of the liquid storage tube;
[0004] Although the flow cytometer laser collimation calibration device is activated by components within the supply mechanism and delivers cleaning liquid into the cleaning mechanism, and the cleaning liquid is sprayed out through components within the cleaning mechanism to clean the sample adhering to the surface of the detection head, the flow cytometer laser collimation calibration device is not convenient for drying the detection head after cleaning, and the water adhering to the detection head can easily interfere with subsequent detection.
[0005] Therefore, we propose a self-cleaning and drying mechanism for the detection head of a flow cytometer. Utility Model Content
[0006] To address the shortcomings of existing technologies, this invention provides a self-cleaning and drying mechanism for the detection head of a flow cytometer, which solves the problem that existing devices are not convenient for drying the cleaned detection head, and that water adhering to the detection head can easily interfere with subsequent detection.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a self-cleaning and drying mechanism for the detection head of a flow cytometer, including a liquid storage tube, a supply mechanism on the right side of the liquid storage tube, and a cleaning spray ring connected to the supply mechanism on the inner wall of the liquid storage tube.
[0008] A drying component is provided on the left side of the liquid storage tube;
[0009] The drying assembly includes a drying ring fixedly fitted inside the liquid storage tube and located above the cleaning spray ring. The drying ring is hollow inside and has evenly distributed air vents on its inner sidewall. A connecting pipe is fixedly installed on the sidewall of the drying ring. The connecting pipe passes through the sidewall of the liquid storage tube and is fixedly installed with a drying chamber. A mesh-like electric heating wire is fixedly fitted on the inner wall of the drying chamber. A fan is provided on the left side of the electric heating wire.
[0010] Preferably, a cover is detachably installed on the side of the drying chamber away from the liquid storage pipe by bolts, and an air inlet is provided on the side wall of the cover. A dustproof plate corresponding to the position of the air inlet is detachably installed on the side of the cover away from the drying chamber by bolts. The dustproof plate can prevent external dust from entering the interior of the drying chamber.
[0011] Preferably, the fan is fixedly installed on the side of the cover near the drying chamber and corresponds to the position of the air inlet. The fan can blow hot air heated by the electric heating wire into the connecting pipe and the drying ring, and then the hot air in the drying ring is discharged through the air outlet, which can dry the cleaned detection head.
[0012] Preferably, a U-shaped tube is provided below the cleaning spray ring, and both ends of the U-shaped tube are fixedly installed on the bottom surface of the cleaning spray ring, wherein the water inside the cleaning spray ring can enter the interior of the U-shaped tube.
[0013] Preferably, a nozzle is fixedly installed on the top surface of the middle part of the U-shaped tube. The nozzle is connected to the cleaning spray ring through the U-shaped tube. Water entering the U-shaped tube can be sprayed out through the nozzle to clean the bottom of the detection head.
[0014] This invention provides a self-cleaning and drying mechanism for the detection head of a flow cytometer. It offers the following advantages:
[0015] 1. The self-cleaning and drying mechanism of the flow cytometer's detection head, by placing the detection head in the middle of the drying ring, heats the air inside the drying chamber through an electric heating wire, and then blows the hot air from inside the drying chamber into the connecting pipe and the drying ring through a fan. The hot air in the drying ring is then discharged through the air outlet, thereby evaporating the water adhering to the surface of the detection head. This achieves the purpose of drying the cleaned detection head, facilitating subsequent detection work and avoiding interference from water. It solves the problem that existing devices are not convenient for drying the cleaned detection head, and that water adhering to the detection head can easily interfere with subsequent detection.
[0016] 2. The self-cleaning and drying mechanism of the flow cytometer's detection head, through the arrangement of the U-shaped tube and the nozzle, allows water from inside the cleaning spray ring to enter the interior of the U-shaped tube. Then, the water inside the U-shaped tube is sprayed onto the bottom surface of the detection head through the nozzle, achieving the purpose of thoroughly cleaning the detection head and improving the cleaning effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1:
[0024] like Figure 1-4As shown: The system includes a liquid storage tube 1, a supply mechanism 2 on the right side of the liquid storage tube 1, a cleaning spray ring 3 connected to the supply mechanism 2 on the inner wall of the liquid storage tube 1, and a drying assembly 6 on the left side of the liquid storage tube 1. The drying assembly 6 includes a drying ring 64 fixedly fitted inside the liquid storage tube 1 and located above the cleaning spray ring 3. The drying ring 64 is hollow inside, and its inner sidewall has evenly distributed air vents 66. A connecting pipe 65 is fixedly installed on the sidewall of the drying ring 64, penetrating the sidewall of the liquid storage tube 1 and fixing a drying chamber 61 thereon. A mesh-like electric heating wire 68 is fixedly fitted on the inner wall of the drying chamber 61. A fan 67 is located on the left side of the electric heating wire 68. A cover 62 is detachably installed on the side of the drying chamber 61 away from the liquid storage tube 1 by bolts. The cover 62 has... An air inlet is provided. A dustproof plate 63 corresponding to the position of the air inlet is detachably installed on the side of the cover 62 away from the drying chamber 61 by bolts. A fan 67 is fixedly installed on the side of the cover 62 near the drying chamber 61 and corresponding to the position of the air inlet. By positioning the detection head in the middle of the drying ring 64, the air inside the drying chamber 61 is heated by the electric heating wire 68. Then, the hot air inside the drying chamber 61 is blown into the connecting pipe 65 and the drying ring 64 by the fan 67. Subsequently, the hot air in the drying ring 64 is discharged through the air outlet 66, thereby evaporating the water adhering to the surface of the detection head. This achieves the purpose of drying the cleaned detection head, so that the detection head can be used for subsequent detection work and avoids the situation where water interferes with the subsequent detection of the detection head.
[0025] Example 2:
[0026] like Figure 2 As shown: A U-shaped tube 4 is installed below the cleaning spray ring 3. Both ends of the U-shaped tube 4 are fixedly installed on the bottom surface of the cleaning spray ring 3. A nozzle 5 is fixedly installed on the top surface of the middle part of the U-shaped tube 4. The nozzle 5 is connected to the cleaning spray ring 3 through the U-shaped tube 4. Through the arrangement of the U-shaped tube 4 and the nozzle 5, the water inside the cleaning spray ring 3 enters the interior of the U-shaped tube 4. Then, the water inside the U-shaped tube 4 is sprayed onto the bottom surface of the detection head through the nozzle 5, achieving the purpose of thoroughly cleaning the detection head and improving the cleaning effect.
[0027] The working principle and usage process of this utility model: The self-cleaning and drying mechanism of the flow cytometer's detection head works as follows: The used detection head is moved into the storage tube 1, and then the supply mechanism 2 is activated to deliver water to the cleaning spray ring 3. The water is sprayed onto the side wall of the detection head through the cleaning spray ring 3, and the water inside the cleaning spray ring 3 also enters the U-shaped tube 4. The water inside the U-shaped tube 4 is then sprayed onto the bottom surface of the detection head through the nozzle 5, thus thoroughly cleaning the detection head. The detection head is then moved upwards to the center of the drying ring 64. The electric heating wire 68 is then activated to heat the air inside the drying chamber 61. The fan 67 is then activated to blow the hot air from inside the drying chamber 61 into the connecting pipe 65 and the drying ring 64. The hot air in the drying ring 64 is then discharged through the air outlet 66, causing the water adhering to the surface of the detection head to evaporate.
