Description

Technical Field

[0001] The utility model relates to the technical field of test smears, in particular to a test smear for making a thin layer of blood film with uniform thickness. Background Art

[0002] A thin-layer blood smear apparatus is a tool used to prepare thin-layer blood smears. This instrument can help laboratories prepare thin-layer smears from blood samples provided by patients. It is very useful in hematological examinations such as blood smear staining and microscopic examination.

[0003] When the smear is used for thin blood film testing, if the thickness of the material on the smear is uneven, the uneven thickness will make some areas too concentrated and other areas too thin, which will cause light and dark differences in the field of view, affecting the observer's judgment of cell structure and thus reducing the accuracy of the test results. Utility Model Content

[0004] The utility model aims to provide a smear tester for making a thin layer of blood film with uniform thickness, which has the advantages of making the thickness of the material on the top of the smear uniform and convenient for detection, and solves the problem that the uneven material on the smear affects the detection.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a test smear device for making a thin layer of blood film with uniform thickness, comprising a support frame and a pull rod, a bearing sleeve is installed on the top of the support frame, a fixing sleeve is embedded in the bottom of the bearing sleeve, a fixing frame is installed on the front side of the bearing sleeve, a hydraulic cylinder 2 is installed on the top of the fixing frame, a coating device is installed on the bottom of the hydraulic cylinder 2, a connecting plate is welded on the side of the support frame, a screw hole is opened on the connecting plate, a screw is threadedly connected to the inner wall of the screw hole, a support plate is movably installed on the top of the screw, a hydraulic cylinder 1 is installed on the top of the support plate, and a scraper is installed on the end of the hydraulic cylinder 1 opposite to the bearing sleeve.

[0006] When using the inspection smear device for making a thin layer of blood film with uniform thickness in the present technical solution, the support frame is fixed to the ground or the bearing structure through the fixing hole of the support frame using bolts and other tools, the smear is placed on the top of the bearing sleeve, and the pull rod is pulled by the fixed plate. The pull rod drives the piston head to move inside the fixed sleeve. When the piston head moves, suction is generated, and the air inside the bearing sleeve enters the fixed sleeve. The bearing sleeve absorbs the smear through the circular hole, and the hydraulic cylinder 2 drives the coating device to descend. After the coating device is adjusted to a suitable height, the material enters the coating device from the feed pipe, and the coating device transports the material to the coating plate through the discharge pipe. The coating plate sprays the material onto the smear, and the hydraulic cylinder 2 drives the coating device to rise, and the screw is rotated by the hand wheel. The screw rotates and moves in the screw hole of the connecting plate, and the screw drives the hydraulic cylinder 1 and the scraper to rise through the support plate. According to the required thickness, after the scraper is adjusted to a suitable height, the hydraulic cylinder 1 pushes the scraper to move slowly, scraping the material on the top of the smear to make the material thickness on the top of the smear uniform.

[0007] Preferably, the top of the bearing sleeve is provided with circular holes in a rectangular array, and the fixing sleeve is connected to the interior of the bearing sleeve. Air can enter the bearing sleeve through the circular holes, and air inside the bearing sleeve can enter the interior of the fixing sleeve.

[0008] Preferably, a pull hole is formed at the bottom of the fixing sleeve, through which the pull rod extends into the fixing sleeve, a piston head is mounted on the top of the pull rod, and a fixing plate is mounted on the bottom of the pull rod. The fixing plate can be used to pull the pull rod, which drives the piston head to move within the fixing sleeve, and the piston head generates suction when it moves.

[0009] Preferably, a slider is installed on the front side of the coating device, and a slide groove is opened on the rear side of the fixing frame, and the slider and the slide groove are slidably connected. The slider limits the coating device, and when the coating device moves, the slider slides in the slide groove to prevent the coating device from shaking.

[0010] Preferably, a hand wheel is installed at the bottom of the screw rod. The screw rod can be rotated using the hand wheel.

[0011] Preferably, a movable hole is formed in the connecting plate on one side of the hand wheel, and a movable rod is installed at the bottom of the support plate, and the bottom of the movable rod passes through the movable hole. The movable rod limits the support plate, and when the support plate is raised or lowered, the movable rod moves in the movable hole to prevent the support plate from shaking.

[0012] Preferably, the coating device is provided with a feed pipe on the side, a discharge pipe at the bottom of the coating device, and a coating plate at the bottom of the discharge pipe. The material enters the coating device from the feed pipe, and the coating device delivers the material to the coating plate through the discharge pipe, and the coating plate sprays the material onto the coating sheet.

[0013] Preferably, the support frame has pipes on both sides, and a rectangular array of fixing holes on the bottom of the support frame. The support frame is fixed to the ground or the supporting structure using tools such as bolts through the fixing holes of the support frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model sets a hydraulic cylinder and a scraper. After the coating plate sprays the material onto the smear, a hand wheel is used to rotate the screw. The screw drives the hydraulic cylinder and the scraper to rise through the support plate. According to the required thickness, the scraper is adjusted to a suitable height. The hydraulic cylinder pushes the scraper to move slowly to scrape the material on the top of the smear, so that the thickness of the material on the top of the smear is uniform, thereby achieving the effect of making the thickness of the material on the top of the smear uniform and facilitating detection.
