Description

Technical Field

[0001] The utility model relates to the technical field of cell detection, in particular to a cell uniform coating device. Background Art

[0002] Smear is to make a thin layer of samples such as cells, tissues, body fluids and evenly apply it on a glass slide. This method is often used for blood tests, bacteria and pathogen detection, etc. The prepared smear needs to be stained and observed under a microscope. The main purpose of the smear is to observe the cell morphology, chromatin and organelles in the sample and the presence of pathogens. Smear examination is a commonly used examination method in clinical practice. It mainly collects tissue from the lesion site for smear. The smear examination is relatively simple to operate and the examination site is relatively wide, including nasal secretion smear examination, cervical cytology smear examination, sputum cytology smear examination, blood smear examination, fungal smear examination, etc. Smear examination can detect cell abnormalities early, can screen various diseases, and has high diagnostic value. When making a cell smear, a coating device is needed to apply the cells to a glass slide.

[0003] When some existing cell coating devices are used, most of them directly drop the sample solution containing cells on the slide, and the sample solution cannot be mixed before coating. The cells in the sample solution are prone to accumulation, and the cells are prone to uneven dispersion during coating.

[0004] For example, a liquid-based thin layer cell detection smear device disclosed in the announcement number CN211927465U is provided with a base, a frame, a sliding rod, a scraper, a spring b and a guide tube. The frame slides in a slide groove on the base through a slider, and the sliding rod drives the scraper to move downward and contact the scraper surface. The guide tube is used to input the sample, and then the scraper can be used to quickly and evenly coat the sample, so that the sample is evenly coated on the glass slide. The structure is simple, the operation is convenient, and the coating effect is good.

[0005] However, when the smear device of the patent is used, the sample is directly poured into the guide tube so that it flows onto the glass slide through the guide tube. The sample solution cannot be mixed before coating. Cells in the sample solution are prone to accumulation, and the cells are prone to uneven dispersion during coating.

[0006] Therefore, it is necessary to invent a cell uniform spreader to solve the above problems. Utility Model Content

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cell uniform coating device, comprising a storage tube, a mixing mechanism and a coating head, the mixing mechanism consisting of a motor housing, a driving motor, a transmission shaft and a mixing blade, the motor housing is threadedly connected to the top of the storage tube, the driving motor is installed inside the motor housing, the transmission shaft is arranged inside the storage tube, the top of the transmission shaft extends to the inside of the motor housing and is transmission-connected to the driving motor, the mixing blade is fixedly connected to the surface of the transmission shaft, the storage tube is fixedly connected with a derivation tube, the bottom end of the derivation tube extends to below the bottom of the storage tube, and the coating head is threadedly connected to the bottom end of the derivation tube.

[0009] The driving motor drives the transmission shaft and the mixing blades to rotate, thereby stirring and mixing the sample solution, so that the cells are evenly dispersed in the sample solution.

[0010] Preferably, a display screen and control buttons are mounted on the surface of the motor housing, and both the display screen and the control buttons are electrically connected to the drive motor.

[0011] The speed and time of the drive motor can be controlled through the control buttons, and the current operating parameters of the drive motor can be displayed through the display screen.

[0012] Preferably, a stopcock is rotatably connected inside the storage tube, and the stopcock is arranged through the outlet tube.

[0013] The outlet tube is sealed with a stopcock.

[0014] Preferably, a through hole is opened in the middle of the plug, and the through hole is located inside the outlet tube. One end of the plug extends to the outside of the storage tube and is fixedly connected with a paddle.

[0015] The cock can be easily rotated by means of a pick, and the through hole is connected with the outlet tube, and the sample solution can be released from the storage tube.

[0016] Preferably, a coating brush is fixedly connected to one side of the bottom of the coating head, a fixing bar is fixedly connected to the other side of the bottom of the coating head, and a ball bearing is installed at the bottom of the fixing bar.

[0017] When the coating head moves, the sample solution is spread evenly on the surface of the slide with the help of a coating brush.

[0018] Preferably, the coating brush is made of medical silicone material, and the ball bearing is made of medical stainless steel material.

[0019] Both the coating brush and the ball are made of medical materials, which is beneficial to improving the safety of the device.

[0020] Preferably, the number of the balls is set to be multiple, and the multiple balls are distributed in a linear array.

[0021] The setting of the ball can reduce the friction between the coating head and the glass slide, making it easier for the coating head to move quickly.

[0022] Preferably, a gripping handle is fixedly connected to one side of the surface of the storage tube, and the mixing blades are made of medical silicone material.

[0023] When the user holds the storage tube, the user puts the palm through the holding handle to prevent accidental loosening.

[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] 1. By arranging a mixing mechanism above the storage tube, the sample solution can be mixed before coating with the help of the mixing mechanism, so that the cells are evenly dispersed in the sample solution, avoiding the dispersion and accumulation of cells in the sample solution, which is conducive to evenly dispersing the cells during coating;

[0026] 2. By setting a ball at the bottom of the coating head, the friction between the ball and the glass slide is small, which can improve the smoothness of the movement of the coating head and facilitate rapid coating on the glass slide. BRIEF DESCRIPTION OF THE DRAWINGS
