Their purpose is to diagnose, prevent, monitor, treat or alleviate diseases, diagnose, monitor, treat, alleviate or compensate for injuries. When doctors test blood, they need to use a smear device to smear blood on a flat glass slide for testing. An existing test smear device (Announcement No.: CN219434473U) has at least the following defects in use:

[0003] In order to ensure the accuracy of the smear, in the above scheme, a piece of smear cotton can only be used for one smearing work, and the smear cotton needs to be replaced after the smearing is completed, which is rather troublesome. Therefore, a test smear device is developed. Utility Model Content

[0023] Example

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A testing smear device includes two conveying shells 201, a conveyor belt 202 is arranged between the opposite sides of the two conveying shells 201, a frame plate is fixedly connected to the top sides of the two conveying shells 201, and a rotating shaft 306 is rotatably connected between the two frame plates. In this embodiment, the conveyor belt 202 can be rotated under the drive of the conveying driving source, and the conveyor belt 202 and the rotating shaft 306 are connected by transmission. Generally, the driving shaft of the conveyor belt 202 and the rotating shaft 306 are connected by transmission through a belt, and the conveyor belt 202 and the rotating shaft 306 are in a state of counter-rotation. A rotating sleeve 303 is rotatably sleeved on the outer side of the rotating shaft 306, and multiple smear sheets 301 are evenly fixedly connected to the outer side of the rotating sleeve 303. A winding elastic ring 302 is fixedly connected to the two sides of the rotating sleeve 303, and the two winding elastic rings 302 are both wound on the outer side of the rotating shaft 306, and the opposite ends of the two winding elastic rings 302 are fixedly connected to the surface of the rotating shaft 306. In this embodiment, a rotating sleeve connection seat 304 is fixedly connected to both sides of the rotating sleeve 303, and two rotating shaft connection seats 305 are arranged on one side of the rotating shaft 306, and each rotating shaft connection seat 305 corresponds to a rotating sleeve connection seat 304, and the corresponding rotating shaft connection seat 305 and rotating sleeve connection seat 304 are fixedly connected to both ends of a winding elastic ring 302. When the rotating shaft 306 rotates, the rotating sleeve 303 and the rotating shaft 306 rotate synchronously under the drive of the winding elastic ring 302, and when the smear sheet 301 is hindered by external force, the winding elastic ring 302 will be compressed, and the rotating shaft connection seat 305 can slide on the surface of the rotating shaft 306, so that the length of the winding elastic ring 302 can change, and when the external force disappears, the winding elastic ring 302 relaxes, so that the rotating sleeve 303 and the rotating shaft 306 are synchronized.

[0026] A glass slide storage frame 102 is fixedly connected to the top side of the two conveying shells 201. A stop plate 103 is fixedly connected to the glass slide storage frame 102 on the side facing the shelf. A plurality of cleaning curtains 104 are fixedly connected to the stop plate 103 on the side facing the conveying shell 201. A flip cover 101 is rotatably connected to the side of the two glass slide storage frames 102 facing away from the conveying shell 201. A compression spring 106 is fixedly connected to the side of the flip cover 101 facing the conveying shell 201. A compression gasket 105 is fixedly connected to the end of the compression spring 106 facing the conveying shell 201. In this embodiment, the glass slides to be smeared are stacked in the glass slide storage frame 102, and the surface of the conveyor belt 202 is relatively rough and has a large friction force, which can drive the glass slides in contact with the conveyor belt 202 out of the glass slide storage frame 102. In order to protect the glass slides, a protective layer can be inserted between the stacked glass slides, and the protective layer is removed by the friction between the cleaning curtain 104 and the glass slides. At the same time, the smear sheet 301 is elastic, and its side facing the conveyor belt 202 will contact the glass slide, and be deformed by the pressure from the glass slide, and hinder the synchronous rotation of the rotating sleeve 303 and the rotating shaft 306, until the glass slide is transported by the conveyor belt 202 to separate from the smear sheet 301, and the reset of the rotating sleeve 303 will allow the next smear sheet 301 to rotate to a position facing the conveyor belt 202, and contact the next glass slide for the next smearing.

[0027] The top sides of the two conveying shells 201 are fixedly connected to a dropper rack 401, and a dropper hole is provided on the top side of the dropper rack 401. The two sides of the dropper rack 401 are respectively in contact with the frame plate and the glass slide storage frame 102. In this embodiment, the staff inserts the dropper into the inner side of the dropper rack 401 through the dropper hole to drop the material to be tested on the surface of the glass slide taken out of the glass slide storage frame 102, which is convenient for the subsequent smearing work.

[0028] It should be noted that the utility model is used as an inspection smear device. When in use, the staff needs to control the rotating drive source so that the smear device can be stopped, which is convenient for the staff to operate the dropper to drip liquid and perform smearing after dripping liquid, and the staff is required to take away the coated glass slide in time.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
