Description

Technical Field

[0001] The invention belongs to the technical field of medical testing tools, and in particular relates to a glass slide smear device for medical testing. Background Art The laboratory department is a bridge between clinical medicine and basic medicine, including clinical chemistry, clinical microbiology, clinical immunology, hematology, fluidology, blood transfusion and other branch disciplines. The laboratory department is generally divided into groups according to the inspection items, and is responsible for the inspection of various human specimens including wards, outpatient and emergency patients, various physical examinations and scientific research every day.

[0002] Blood smears are often used in medical examinations. Blood smears are a process of spreading blood evenly in a certain direction using a specific method. Microscopically, cells are changed from spherical to flat or nearly flat and spread on a glass slide. When making a blood smear, hold the glass slide with your left hand and spread and flatten it with a cover glass in your right hand. During this process, the glass slide should be held horizontally and steadily, and the right hand should move the slide evenly.

[0003] However, due to the large amount of blood smears used in medical examinations and the long-term manual operation, it is difficult for medical staff to keep their hands stable, which can easily cause problems such as uneven scraping of blood specimens, affecting subsequent examinations. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a slide smear device for medical examination, and the technical solution adopted is as follows: A glass slide smear device for medical examination comprises an operating table arranged above a base, a recessed platform for placing a glass slide is arranged above the operating table, a plurality of air holes are opened on the surface of the platform, the bottom of the air holes is connected to the air cavity inside the operating table, a space for installing an air pump is arranged inside the operating table and below the air cavity, and an air suction pipe of the air suction pump is connected to the air cavity through a pipeline; A plurality of exhaust holes are provided on one side of the operating table, a boss extending upward is provided on the other side of the operating table, a movable slider is provided above the boss, a mounting frame is provided on one side of the slider, a pull rod is provided at one end of the mounting frame, a guide column inserted into the mounting frame is provided at both ends of the pull rod, a pressure plate is connected to the end of the guide column, a spring is installed at the end of the guide column, and a cover glass is clamped between the pressure plate and the mounting frame.

[0005] Furthermore, a controller connected to the vacuum pump is provided on one side of the operating table, and the start and stop of the vacuum pump can be controlled by the controller.

[0006] Furthermore, a storage rack is installed on one side of the operating table where the exhaust hole is set. In the storage rack, multiple layers of pallets are arranged from top to bottom. Multiple slides that have completed smearing work can be placed above the pallets. While temporarily storing the slides, the drying efficiency of the liquid on the surface of the slides can be accelerated, thereby improving the inspection efficiency.

[0007] Furthermore, a collection frame is placed above the base and on one side of the operating table, and the used cover glasses can be collected in the collection frame. When the collection frame is full, the cover glasses can be taken out for unified processing.

[0008] Furthermore, a rubber pad is laid on the surface of the platform in the operating table, and through holes are also opened on the surface of the rubber pad at positions corresponding to the air holes. The rubber pad can reduce the friction between the slide and the platform.

[0009] Furthermore, a screw rod passing through the slider is provided at one end of the mounting frame, and a fixing nut is installed at the position where the screw rod protrudes from the slider. Through the cooperation of the fixing nut and the screw rod, the mounting frame can be fixed on one side of the slider at any angle.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an operating table for placing slides and a mounting frame for holding cover slips, so that the work intensity of medical personnel can be reduced in a large number of repeated smear preparation processes. Medical personnel are no longer required to keep both hands lifted for a long time to perform high-precision operations of aligning the cover slip and the slide and pushing the slide with both hands, thereby reducing the problem of poor smear quality caused by hand fatigue.

[0011] The present invention can firmly fix the glass slide on the operating table by setting the vacuum pump, ensuring that the glass slide will not move during the smearing process, and can also use the airflow discharged by the vacuum pump to air-dry the glass slide placed in the storage rack after the smearing work, thereby improving work efficiency.

[0012] The present invention arranges the inner edge of the mounting frame and the edge of the platform in the lower operating table on the same vertical line, so as to facilitate the quick alignment of the clamped cover glass and the slide glass, simplify the operation process, improve work efficiency, and effectively reduce human errors to ensure the quality of the smear.

DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0016] As attached Figure 1-7 shown.

[0017] A slide smear device for medical examination comprises an operating table 1 arranged above a base 2, a recessed platform for placing a slide a is arranged above the operating table 1, and a layer of rubber pad 12 is laid on the surface of the platform to reduce the wear of the slide a; as shown in the attached Figure 3 As shown, a plurality of circular air holes 13 are provided on the surface of the platform, and the lower part of the air holes 13 is connected with the air cavity 11 inside the operating table 1. A space for installing an air pump 5 is provided inside the operating table 1 and below the air cavity 11. The air suction pipe of the air pump 5 is connected with the air cavity 11 through a pipeline, and the air outlet pipe of the air pump 5 is not connected. When in use, the glass slide a is placed on the position where the air hole 13 is provided above the platform, and one corner of the glass slide a is aligned with the edge of the platform, and the bottom of the glass slide a is in contact with the rubber pad 12. After the air pump 5 is started, negative pressure is generated in the air cavity 11 and the air hole 13, which can firmly adsorb the glass slide a on the platform, thereby ensuring the stability of the glass slide during the smearing process.

[0018] A plurality of exhaust holes 15 are provided on one side of the operating table 1 for exhausting the air extracted by the vacuum pump 5. A storage rack 4 is installed on the side of the operating table 1 where the exhaust holes 15 are provided. A plurality of layers of support plates 41 are provided from top to bottom in the storage rack 4 for storing the glass slides a after smearing. The gas exhausted from the operating table 1 after the vacuum pump 5 is started can be used to quickly dry the liquid on the surface of the glass slide a, thereby improving the smearing efficiency.

[0019] A controller 3 is provided on one side of the operating table 1, and the start and stop of the vacuum pump 5 can be controlled by the controller 3. An upwardly extending boss is provided on the other side of the operating table 1, and a movable slider 6 is provided above the boss. The bottom of the slider 6 is a T-shaped plate, and the T-shaped plate cooperates with the slide groove 14 of the T-shaped structure in the boss so that the slider 6 can slide along the boss.

[0020] A mounting frame 7 is provided on the side of the slide 6 facing the slide glass a. Figure 4 , 6 As shown, a screw rod 71 passing through the slider 6 is provided at one end of the mounting frame 7, and a fixing nut 8 is threadedly installed at one end of the screw rod 71 passing through the slider 6. Through the cooperation of the fixing nut 8 and the screw rod 71, the mounting frame 7 can be fixed on one side of the slider 6 at any angle.

[0021] A pull rod 72 is provided at the other end of the mounting frame 7, and a guide column 73 inserted into the inner side of the mounting frame 7 is provided at both ends of the pull rod 72. A pressure plate 75 is connected to one end of the guide column 73 located on the inner side of the mounting frame 7, and a spring 74 is mounted on the outer side of the guide column 73 near the pressure plate 75. Under the action of the spring 74, the pressure plate 75 can be tightly attached to the cover glass b, thereby fixing the cover glass b.

[0022] A collection frame 9 for cover glass b is placed above the base 2 and on one side of the operating table 1. After a smearing of the slide a is completed, a new cover glass b needs to be replaced. The replacement process is as follows: push the mounting frame 7 to the top of the collection frame 9. At this time, just pull the pull rod 72, the pressure plate 75 is separated from the cover glass b, and the old cover glass b will fall into the collection frame 9; After replacing the new slide a, pull the mounting frame 7 back to the top of the slide a. At this time, put the new cover glass b into the mounting frame 7 so that the lower end of the cover glass b contacts the upper surface of the slide a. Then release the pull rod 72, the spring 74 returns to its original state, and the pressure plate 75 is again tightly fixed to the cover glass b.

[0023] As attached Figure 1 , 2 As shown, the inner edge of the mounting frame 7 is on the same vertical line as the edge of the platform for placing the slide a in the lower operating table 1. After the slide a is placed, when a new cover glass b is placed, it is only necessary to ensure that the edge of the cover glass b is in contact with the inner edge of the mounting frame 7 to ensure that the cover glass b is accurately aligned with the slide a, which is convenient for subsequent pushing operations.

[0024] Since the subsequent film pushing operation requires a certain angle between the cover glass b and the slide a, and the connection structure between the mounting frame 7 and the slider 6 can just meet this requirement, by adjusting the screw 71 and the fixing nut 8, the installation angle of the mounting frame 7 can be precisely controlled to meet the film pushing requirement.

[0025] The complete usage process is: first place the slide a on the platform in the operating table 1, start the vacuum pump 5 through the controller 3, firmly adsorb the slide a on the platform, then move the mounting frame 7 to the middle position above the slide a, put in a new cover glass b, ensure that its edge contacts the inner edge of the mounting frame 7, and the lower end of the cover glass b contacts the upper surface of the slide a, then release the pull rod 72, and the spring 74 pushes the pressure plate 75 to press the cover glass b to complete the fixation.

[0026] Then use a dropper to drop the liquid between the cover glass b and the handle of the slide a. Figure 1 , 2 As shown, one end of the slide a protruding from the operating table 1 is a hand-held portion. Thereafter, the medical staff pulls the mounting frame 7 toward the hand-held portion of the slide a to make the lower end of the cover glass b contact with the dripping liquid. Under the action of the surface tension of the liquid, the liquid spreads at the lower end of the cover glass b. At this time, by pushing the mounting frame 7 backward, the liquid can be pushed away on the slide a to form a uniform smear layer.

[0027] After the smearing is completed, the mounting frame 7 is pushed to the top of the collecting frame 9, the pull rod 72 is pulled, the pressure plate 75 is separated from the cover glass b, and the old cover glass b falls into the collecting frame 9. The vacuum pump 5 is then stopped by the controller 3, and the smeared slide a can be removed from the operating table 1 and placed on the tray 41 in the storage rack 4 on one side for temporary storage. After the liquid above the slide a is dried, subsequent processing can be carried out.

[0028] After that, a new slide glass a is placed and the above steps are repeated to continuously carry out the smearing operation. The device can reduce the workload of medical staff and improve the efficiency and quality of smearing.

[0029] In the above process, in order to prevent the air pump 5 from dispersing the liquid above the glass slide a in the storage rack 4 due to excessive airflow, the air pump 5 adopts a 12V low-power design to ensure the gentleness of its exhaust airflow.

[0030] Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
