Description

A medical smear device Technical Field

[0001] This utility model relates to the technical field of medical examination smears, specifically to a smear device for medical examination. Background Technology

[0002] Smears are a diagnostic method for detecting pathogens in blood or tissues, including gonococci, cryptococci, syphilis spirochetes, and diphtheria corynebacterium. Normally, a patient's blood or other bodily fluids are placed on a smear glass, and a coverslip is placed over it. With the development of modern medical technology, smear procedures are increasingly being replaced by mechanical operations, making medical smear procedures more convenient and efficient.

[0003] In response to this, Chinese Patent No. CN215065614U proposes a smear device for medical testing. This invention uses a coating plate as a scraper structure to apply a blood film to the surface of a glass slide. The sliding frame supports the slider and the liquid channel supports the coating plate to move smoothly along the surface of the glass slide, thereby ensuring the uniformity of the blood film coating on the glass slide surface and improving the accuracy of the test. At the same time, the thickness of the blood film can be adjusted according to different test requirements, making it highly practical.

[0004] However, the top and bottom coverslips need to be aligned during smear preparation, and the mucus and blood inside need to be prevented from flowing out of the outside of the coverslip during the cover-up process. The above-mentioned technical solutions and existing medical smear devices do not have a positioning mechanism to keep the coverslips aligned during the smear preparation process, nor do they have a limiting structure for centered dripping. In view of this, this design proposes a smear device for medical testing. Summary of the Invention

[0005] The purpose of this invention is to provide a medical smear device to solve the problems mentioned in the background art. To achieve the above objective, this invention proposes a medical smear device, comprising a smear base and a smearing mechanism and a smear-picking mechanism, both mounted on the top of the smear base and distributed vertically.

[0006] The coating mechanism includes four triangular positioning plates installed at the center of the top of the coating base. Limiting grooves are provided on both sides of one end of the top of the coating base. A lifting frame is slidably connected between the inner walls of two of the limiting grooves. A first electric telescopic rod is installed at both ends of the lifting frame. A connecting frame is fixedly provided at the output end of the two first electric telescopic rods. Rubber push rods are provided on both sides of the bottom of the connecting frame. A positioning frame is fixedly provided at the center of the connecting frame. Multiple guide wheels are equidistantly rotatably connected at the center of both sides of the four triangular positioning plates on the top of the coating base.

[0007] In one example, each of the guide wheels is fitted with a rubber pad on its outer wall, and a second electric telescopic rod is installed on one side of the top of the coating base, with the output end of the second electric telescopic rod fixedly connected to the bottom of the lifting frame.

[0008] In one example, the paddle mechanism includes a connecting groove located in the middle of the inner wall of the smear base, and a slide rod is inserted through the inner wall of the connecting groove.

[0009] In one example, a telescopic shaft is inserted at the middle position of the top of the smear base, and the bottom of the telescopic shaft passes through the inner wall of the connecting groove and contacts the outer wall of the slide rod.

[0010] In one example, a button is fixedly mounted on one end of the slide rod through one side of the outer wall of the smear base, and a spring is sleeved on the outer wall of one end of the slide rod, with the two ends of the spring fixed to one side of the outer wall of the smear base and one side of the button, respectively.

[0011] In one example, a control switch is fixedly provided on one side of the top of the smear base, and both the first electric telescopic rod and the second electric telescopic rod are electrically connected to an external power source through the control switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a coating mechanism, during coating, the positioning frame positions the dropper in the center, so that the droplet is pressed against the middle of the lower cover glass slide. During the later cover glass process, it is not easy to squeeze and cause the liquid to flow to the outside of the glass slide. With the compression and pushing of the connecting frame and the rubber push rod, as well as the positioning of the guide wheel and the triangular positioning frame, the edges of the glass slides are kept neat after they are overlapped. This solves the problem in the prior art that mechanical coating cannot guarantee the edges of the upper and lower glass slides are neat and that the droplets are easy to flow to the outside of the glass slide.

[0018] 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.

[0019] Please refer to Figures 1-4. This utility model provides a technical solution: a medical testing smear device, including a smear base 1 and a smearing mechanism 2 and a smearing mechanism 3, which are installed on the top of the smear base 1 and distributed vertically.

[0020] The coating mechanism 2 includes four triangular positioning pieces 201 installed at the middle of the top of the coating base 1. Limiting grooves 202 are opened on both sides of one end of the top of the coating base 1. A lifting frame 203 is slidably connected between the inner walls of the two limiting grooves 202. First electric telescopic rods 204 are installed at both ends of the lifting frame 203. A connecting frame 205 is fixedly provided at the output end of the two first electric telescopic rods 204. Rubber push rods 206 are located on both sides of the bottom of the connecting frame 205. A positioning frame 207 is fixedly provided in the middle of the connecting frame 205. Multiple guide wheels 208 are equidistantly rotatably connected at the middle of the two sides of the four triangular positioning pieces 201 at the top of the coating base 1.

[0021] In use, the lower cover slide is positioned between the four triangular positioning pieces 201 to limit its movement. Then, the dropper is centered using the positioning frame 207 on the upper connecting frame 205, ensuring that the dropper passes through the positioning frame 207 and presses the liquid against the slide, thus keeping it perfectly centered. This prevents liquid from flowing out of the slide when covering the slide later. The upper cover slide is then placed on top of the lower cover slide, ensuring that one side completely covers the droplet. The second electric telescopic rod 210 is activated, causing the lifting frame 203 to slide between the limiting grooves 202, and the first electric telescopic rod 204 is activated. The connecting frame 205 is moved to the edge of the cover glass until the bottom of the rubber push rod 206 contacts the upper cover glass. Then the first electric telescopic rod 204 is retracted, so that the upper cover glass moves slowly above the lower cover glass under the push of the rubber push rod 206. Under the guidance and traction of the guide wheels 208 between the two sides of the triangular positioning piece 201, the edges of the upper and lower cover glass are kept aligned and squeezed to make them fit tightly together, improving the quality of the coating. This solves the problem in the prior art that mechanical coating cannot guarantee the alignment of the upper and lower glass edges and that droplets are easy to flow to the outside of the glass.

[0022] Furthermore, each guide wheel 208 is fitted with a rubber pad 209 on its outer wall. A second electric telescopic rod 210 is installed on one side of the top of the smear base 1, and the output end of the second electric telescopic rod 210 is fixedly connected to the bottom of the lifting frame 203. During the process of the upper cover glass slide moving and coinciding with the lower cover glass slide, the guide wheel 208 is used to limit the movement and keep it aligned. During this process, the glass slide contacts the rubber pad 209 on its outer side, which can reduce wear.

[0023] Furthermore, the paddle mechanism 3 includes a connecting groove 301 located in the middle of the inner wall of the coating base 1. A slide rod 302 is inserted through the inner wall of the connecting groove 301, and the two ends of the slide rod 302 have different diameters, with the diameter of the rear end being larger than that of the front end, so that when the surface of the rear end contacts the telescopic shaft 303 during the sliding process, it can be lifted up.

[0024] A telescopic shaft 303 is inserted at the middle of the top of the smear base 1, and the bottom of the telescopic shaft 303 passes through the inner wall of the connecting groove 301 and contacts the outer wall of the slide rod 302.

[0025] A button 304 is fixedly installed on one side of the outer wall of the coating base 1 through one end of the slide rod 302. A spring 305 is sleeved on the outer wall of one end of the slide rod 302, and the two ends of the spring 305 are fixedly connected to one side of the outer wall of the coating base 1 and one side of the button 304, respectively. After the coating is completed, it is not easy for the operator to remove it due to its small thickness. Forcibly pulling it out may damage the coating. At this time, the button 304 can be pressed to push the slide rod 302 to slide in the connecting groove 301, so that the end of the slide rod 302 with a larger diameter squeezes the telescopic shaft 303 and pushes it out of the top of the coating base 1, thereby lifting the coating, making it easy for the operator to remove the coating and preventing damage to the coating. After removing the coating, the button 304 is released, and the slide rod 302 returns to its original position under the elastic action of the spring 305. The telescopic shaft 303 retracts into the interior of the coating base 1, and the next coating operation can continue.
