Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a rapid smear device. Background Art
[0002] The laboratory is a bridge between clinical medicine and basic medicine. It is an experimental place that uses various specimens from patients as its working objects. It helps doctors screen and diagnose diseases through various medical testing technologies. For example, in order to carefully observe the morphology of cells, microorganisms, etc., it is helpful for the diagnosis and differential diagnosis of diseases. It is usually necessary to make a smear specimen. When making a smear specimen, take a drop of fresh blood and place it on a glass slide. Then hold the glass slide in the left hand and the pusher in the right hand and move it from the front of the blood to the back to contact the blood drop, so that the blood drop spreads along the edge of the pusher. The pusher is at an angle of 30 to 45 degrees to the glass slide and moves forward at a uniform and stable speed until a blood smear is formed. In order to facilitate the inspection personnel to make smear specimens, a rapid smearer has appeared.
[0003] When the smearer in the prior art is used, the slide is placed on the smearer, and then the pusher is pushed directly from one end of the slide to the other end to evenly smear the blood on the slide. Although it is more convenient than the traditional manual production, the blood is not completely spread on the edge of the pusher before smearing the blood, which can easily lead to uneven blood distribution. In addition, the blood is in front of the pusher, and when the pusher pushes the blood, it suddenly collides with the blood, which can easily cause blood to splash, which may lead to waste of specimens and contamination of the smearer. Therefore, in response to the above problems, we propose a rapid smearer. Utility Model Content

DETAILED DESCRIPTION
[0034] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0035] like Figure 1-5 As shown, a rapid smear device comprises an operating table 1, wherein both ends of the operating table 1 are provided with a slide groove 2, and both slide grooves 2 are slidably connected with a slider 3, and the two sliders 3 are respectively connected with springs 4 between the inner walls of the two slide grooves 2, and both slide grooves 2 are respectively provided with a limit assembly 5 for limiting the two sliders 3, and a telescopic member 6 is provided above the operating table 1, and both ends of the telescopic member 6 are respectively connected with the two sliders 3, and a push piece 7 is provided at the upper end of the telescopic member 6, and a glass slide groove 8 adapted to the width of the push piece 7 is provided on the operating table 1;
[0036] Specifically, when it is necessary to make a smear specimen, the slide is placed in the slide groove 8. At present, the slides used clinically are all of the same size. Therefore, the size of the slide groove 8 in the utility model can just match the size of the slide. The slide is placed in the slide groove 8, and then blood is dripped on the slide. The position of the blood on the slide is at one end away from the limiting component 5. The slider 3 is slid. At this time, the slider 3 drives the telescopic member 6 to move, and the telescopic member 6 drives the push piece 7 to move. The push piece 7 is inclined, and the inclination angle can be between 30° and 45°. When the push piece 7 contacts the blood, the degree of blood spreading on the edge of the push piece 7 is observed. The push piece 7 can be transparent, and then the hand is released. At this time, under the elastic action of the spring 4, the slider 3 drives the telescopic member 6 to reset. When the slider 3 returns to its original position, it is limited by the limiting component 5 to avoid rebound shaking. In this process, the blood is always at the bottom of the push piece 7. Therefore, not only can the blood be evenly smeared on the slide, but also the splashing of blood can be avoided, and the waste of specimens and the contamination of the smearer can be avoided.
[0037] Preferably, the telescopic member 6 includes a connecting rod 601 and a telescopic rod 602 connected to both ends of the connecting rod 601, the bottoms of the two telescopic rods 602 are respectively connected to the two sliders 3, and the top of the push piece 7 is connected to the connecting rod 601, wherein the telescopic rod 602 can be an electric telescopic rod 602, a hydraulic telescopic rod 602, etc. After the blood is evenly smeared, the push piece 7 is lifted by the telescopic effect of the telescopic rod 602, and then the slide is taken out conveniently.
[0038] Preferably, the two groups of limit assemblies 5 both include a limit groove 501 and a limit block 502 slidably connected to the limit groove 501, the limit groove 501 is opened on the inner bottom surface of the slide groove 2, a tension spring 9 is connected between the bottom of the limit block 502 and the limit groove 501, the limit block 502 is provided with an inclined portion 10, and the bottom of the slider 3 is provided with an inclined portion 11. When the telescopic member 6 rebounds under the elastic action of the spring 4, the inclined portion 11 on the slider 3 approaches and conflicts with the inclined portion 10 on the limit block 502, so that the limit block 502 slides downward to squeeze the tension spring 9, and the limit block 502 enters the limit groove 501, and at the same time makes the slider 3 continue to move forward. When the inclined portion 11 is separated from the inclined portion 10, under the elastic action of the tension spring 9, the upper end of the limit block 502 comes out of the limit groove 501, and then conflicts with the slider 3 to prevent the slider 3 from rebounding.
[0039] Preferably, the bottom of the two limit blocks 502 are connected to a pull rod 12, one end of the two pull rods 12 extends to the outside of the operating table 1, and the bottom of the two pull rods 12 are commonly connected to an operating rod 13. When it is needed to be used next time, pull the operating rod 13, and the operating rod 13 drives the two pull rods 12 to pull down, and then drives the two limit blocks 502 to move downward. At this time, the two limit blocks 502 enter the interior of the two limit grooves 501, and the two sliders 3 are released from the limit, so that it is convenient to make the smear specimen again.
[0040] Preferably, there are multiple glass slide slots 8 and push pieces 7, and the positions of the multiple glass slide slots 8 and the multiple push pieces 7 correspond one to one. By setting up multiple glass slide slots 8 and push pieces 7, the glass slides can be placed in the multiple glass slide slots 8 respectively, and then the telescopic rod 602 controls the push pieces 7 to move downward, and each push piece 7 just falls on the glass slide and contacts the glass slide. Then, when the telescopic part 6 moves, it drives the multiple push pieces 7 to move, and multiple specimen smears can be made at the same time.
[0041] Preferably, a plurality of the slide grooves 8 are provided with through holes 14. After the smear specimen is prepared, the inspector inserts his finger into the through hole 14 from the bottom of the operating table 1 and then pushes the slide upward. When the slide is lifted up, the slide can be taken out.
[0042] Preferably, the bottom of the operating table 1 is connected to a plurality of support rods 15, and the bottoms of the plurality of support rods 15 are commonly connected to a base 16, and an anti-skid pad 17 is provided at the bottom of the base 16, and an anti-skid pattern is provided on the anti-skid pad 17, wherein the anti-skid pad 17 may be made of rubber, silicone or other materials. The operating table 1 may be supported by the arrangement of the plurality of support rods 15 and the base 16, and the friction between the base 16 and the desktop is increased by the arrangement of the anti-skid pad 17 and the anti-skid pattern, so that when making a smear specimen, the base 16 is prevented from sliding, thereby improving stability and avoiding affecting the making of the smear specimen.
[0043] The working principle and use process of the utility model are as follows: when using the device, the base 16 is placed on the table. At this time, the setting of the anti-skid pad 17 can increase the friction between the base 16 and the table, thereby increasing stability. Then, the glass slide is placed in the glass slide groove 8, and blood is dripped on the end of the glass slide away from the limiting component 5. Then, the push piece 7 is at the end of the glass slide away from the blood. Then, the operating rod 13 is pressed downward. At this time, the operating rod 13 drives the pull rod 12 and the limiting block 502 to move downward, so that the limiting block 502 enters the limiting groove 501. At the same time, the tension spring 9 is squeezed, and the two sliders 3 are released from the limit. Then, the telescopic rod 602 moves the push piece 7 downward, so that the push piece 7 contacts the glass slide. Then, the connecting rod 601 is pulled. At this time, the connecting rod 601 drives the telescopic rod 602 and the slider 3 to move in the slide groove 2. The spring 4 is squeezed and deformed, and then the push piece 7 approaches the blood. When the slide 3 is in contact with the blood, the blood spreads on the bottom edge of the push piece 7, and then the user lets go. Under the elastic action of the spring 4, the push piece 7 is away from the blood and drives the blood to spread evenly on the glass slide. At the same time, the inclined surface 11 on the slider 3 contacts the inclined surface 10 on the limit block 502, and then the limit block 502 is pushed downward. When the limit block 502 enters the limit groove 501, the slider 3 continues to move forward. Then, when the slider 3 is away from the limit block 502, under the elastic action of the tension spring 9, the limit block 502 rises to limit the slider 3. The smear specimen is completed. Then, the push piece 7 is raised by the telescopic rod 602, and the finger passes through the through hole 14 from the bottom of the operating table 1, and then the slide is lifted up and taken out. The utility model can not only evenly smear the blood on the slide, but also avoid blood splashing, avoid specimen waste and contamination of the smearer.
