Description

Technical Field

[0001] The utility model relates to the technical field of smear devices; more specifically, it relates to a medical detection smear device. Background Art

[0002] Clinical medicine needs to detect various sample pathogens to determine the cause and condition of patients, so that medical staff can prescribe the right medicine and rescue patients from diseases as soon as possible. Smearing is an essential task in clinical medicine detection and an important basic task in the detection department. Smearing is a detection method for pathogens including Neisseria gonorrhoeae, Cryptococcus neoformans, Treponema pallidum, Corynebacterium, etc. in blood or tissues.

[0003] Currently, in the process of using smears in the prior art, since most medical staff use cotton swabs to dip samples from test tubes during the smear production process, then drop the samples on the glass slides, and then use the cover glass to spread the blood drops on the glass slides, so that the blood diffuses along the contact surface of the two glass slides. However, in the above operations, medical staff need to operate on two glass slides with both hands respectively. One hand is used to keep the stability of the glass slide, and the other hand is used to keep the cover glass moving smoothly. It is very easy to have the phenomenon that the glass slide is unstable or the force of the cover glass is unevenly controlled. And medical staff can generally only make one smear at a time, which is very troublesome and time-consuming and laborious. To a certain extent, it reduces the work efficiency of medical staff. Therefore, there is an urgent need for a medical detection smear device to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above defects of the prior art, the utility model provides a medical detection smear device to solve the problems existing in the above background art.

[0005] The utility model provides the following technical solutions: A medical detection smear device, comprising:

[0006] A support bottom plate, on the upper surface at the four corners of the support bottom plate, electric telescopic rods are installed, and at the middle position of the upper surface of the support bottom plate, a bearing structure is arranged, and on the upper surfaces of the four groups of electric telescopic rods, a spreading structure is arranged;

[0007] The bearing structure includes a workbench, and the workbench is fixedly connected to the middle position of the upper surface of the support bottom plate;

[0008] The spreading structure includes an installation frame, and the upper ends of the four groups of electric telescopic rods are respectively fixedly connected to the bottom surfaces at the four corners of the installation frame.

[0009] Preferably, the bearing structure further includes a moving groove and a placing groove, and the interiors of the moving groove and the placing groove are in communication with each other. Moreover, there are multiple groups of the moving groove and the placing groove. Multiple groups of the moving grooves are respectively opened inside the outer surfaces on both sides of the workbench, and multiple groups of the placing grooves are respectively opened inside both sides of the upper surface of the workbench. A threaded rod is threadedly connected inside the outer surfaces on both sides of the workbench, and one end of the threaded rod is connected to a jacking block through a bearing, and the jacking block is inserted into the moving groove. A placing block is snap-fitted and slidably connected inside the placing groove. When medical staff use the device, a glass slide can be placed on the upper surface of the placing block inside the placing groove, thereby facilitating the stability of the glass slide when making a smear.

[0010] Preferably, the outer surfaces of one end of the jacking block and one end of the bottom of the placing block are both inclined, and the outer surface of one end of the jacking block is in contact with the outer surface of one end of the bottom of the placing block. The bottom of the inclined surface of the placing block is arc-shaped. By rotating the threaded rod, the jacking block can move inside the moving groove, and the arc-shaped design facilitates the jacking block to jack up the placing block upward.

[0011] Preferably, rectangular sliding grooves are opened on the inner wall surfaces on both sides of the placing groove, rectangular sliding blocks are arranged on the outer surfaces on both sides of the placing block, and the rectangular sliding blocks are snap-fitted and slidably connected inside the rectangular sliding grooves. When the placing block moves, the rectangular sliding blocks move synchronously inside the rectangular sliding grooves, making the movement of the placing block more stable.

[0012] Preferably, the spreading structure further includes a motor, and a motor is installed on the outer surface of one side of the mounting frame. Moreover, there are multiple groups of the motor. A lead screw is fixedly connected to the output end of the motor. Limit grooves are opened on both sides of the bottom surface of the mounting frame, and there are multiple groups of the limit grooves. A communication groove is opened inside the middle position of the bottom surface of the mounting frame, and the lead screw is inserted into the communication groove, and one end of the lead screw is connected to the limit groove through a bearing. When the motor is started, the lead screw can rotate inside the limit groove and the communication groove. The communication groove can prevent the mounting frame from hindering the rotation of the lead screw.

[0013] Preferably, moving blocks are threadedly connected to the outer surfaces of both ends of the lead screw, and a spreading plate is fixedly connected to the bottom surface of the moving block. The two moving blocks and the spreading plate are opposite to each other, and the internal threads of the parts of the outer surfaces of both ends of the lead screw where the two moving blocks are threadedly connected are opposite to each other. The outer surface of the upper end of the moving block is snap-fitted and connected inside the limit groove, and the width dimension of the moving block is adapted to the width dimension inside the limit groove. The angle of the spreading plate is 45 degrees. This design can make the moving blocks threadedly connected to the outer surfaces of both ends of the lead screw move outwards or inwards synchronously when the lead screw rotates, thereby driving the spreading plate to evenly smear the sample on the glass slide at an angle of 45 degrees.

[0014] Technical effects and advantages of the present utility model: By placing the glass slide inside the placement groove, then rotating the threaded rod, the ejecting block can push the placement block to move upward. At this time, the height dimension of the placement block can be adjusted according to the actual thickness of the glass slide, so as to support the glass slide through the placement block, without the need for staff to hold the glass slide steady by hand. Subsequently, by starting the electric telescopic rod, the mounting frame can be driven to move upward or downward, and the bottom surface of the spreading plate is made to fit the upper surface of the glass slide. At this time, the blood sample can be smoothly spread by the spreading plate, thus eliminating the need for medical staff to operate by hand, and to a certain extent avoiding the phenomenon of the glass slide being unstable due to poor control or uneven force on the cover glass.

[0015] Through the design of multiple groups of placement grooves, multiple glass slides can be placed when the device is in use. Starting multiple groups of motors can drive multiple groups of lead screws to rotate, and thereby multiple groups of moving blocks drive multiple groups of spreading plates to move, so as to spread the blood sample on the surface of the glass slide through the spreading plates, enabling medical staff to make multiple groups of smears at one time, which is relatively time-saving and labor-saving, improving the work efficiency of medical staff to a certain extent. Moreover, its overall structure is simply and reasonably designed, with high practicability and is easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, in combination with the drawings in the present utility model, the technical solutions in the present utility model will be clearly and completely described. In addition, the forms of each structure described in the following embodiments are merely examples, and the smear device involved in the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1 - 5 shown, this embodiment proposes a medical detection smear device, including:

[0025] A support base plate 1, electric telescopic rods 2 are installed on the upper surfaces at the four corners of the support base plate 1, and a bearing structure 3 is arranged at the middle position of the upper surface of the support base plate 1. A spreading structure 4 is arranged on the upper surfaces of the four groups of electric telescopic rods 2;

[0026] The bearing structure 3 includes a workbench 31, and the workbench 31 is fixedly connected to the middle position of the upper surface of the support base plate 1. The bearing structure 3 further includes a moving groove 32 and a placing groove 33, and the inside of the moving groove 32 is connected to the inside of the placing groove 33, and both the moving groove 32 and the placing groove 33 are provided with multiple groups. Multiple groups of moving grooves 32 are respectively opened inside the outer surfaces on both sides of the workbench 31, and multiple groups of placing grooves 33 are respectively opened inside the upper surfaces on both sides of the workbench 31. Through the design of multiple groups of placing grooves 33, medical staff can place multiple groups of glass slides at one time, which improves the work efficiency of medical staff to a certain extent;

[0027] A threaded rod 36 is threadedly connected to the inside of the outer surfaces on both sides of the workbench 31, and one end of the threaded rod 36 is connected to a top block 34 by a bearing, and the top block 34 is inserted into the inside of the moving groove 32. A placing block 35 is clamped and slidably connected to the inside of the placing groove 33. When the threaded rod 36 is rotated clockwise, the top block 34 can be driven to move inward inside the moving groove 32. At this time, the top block 34 can push the placing block 35 upward, so that the placing block 35 moves upward inside the placing groove 33. When the threaded rod 36 is rotated counterclockwise, the top block 34 can be driven to move outward inside the moving groove 32. At this time, the placing block 35 moves downward inside the placing groove 33 due to its own gravity. Thus, the glass slide can be placed on the upper surface of the placing block 35 inside the placing groove 33, without the need to hold the glass slide steady by hand, and the height of the placing block 35 can be adjusted according to the thickness of the glass slide. At the same time, it is convenient to push the glass slide out of the placing groove 33 and take it out after the sample is spread;

[0028] The outer surfaces of one end of the ejector block 34 and one end of the bottom of the placement block 35 are both inclined, and the outer surface of one end of the ejector block 34 is in contact with the outer surface of one end of the bottom of the placement block 35. The bottom of the inclined surface of the placement block 35 is arc-shaped. When the threaded rod 36 is rotated clockwise, the bottom surface of one end of the ejector block 34 is inserted into the arc-shaped bottom surface of the placement block 35, and the placement block 35 is lifted upward through the inclined surfaces where the ejector block 34 and the placement block 35 are in contact with each other, so as to facilitate adjusting the height position of the placement block 35 inside the placement groove 33;

[0029] Rectangular sliding grooves are formed on the inner wall surfaces on both sides of the placement groove 33. Rectangular sliding blocks are arranged on the outer surfaces on both sides of the placement block 35, and the rectangular sliding blocks are snap-fitted and slidably connected inside the rectangular sliding grooves. When the placement block 35 moves upward or downward inside the placement groove 33, the rectangular sliding blocks move synchronously inside the rectangular sliding grooves, so that the placement block 35 can move more stably.

[0030] Embodiment 2

[0031] As Figure 4 shown, based on the same concept as the above embodiment, this embodiment also proposes: The spreading structure 4 includes a mounting frame 41. The upper ends of the four groups of electric telescopic rods 2 are respectively fixedly connected to the bottom surfaces of the four corners of the mounting frame 41. The spreading structure 4 also includes a motor 42, and the motor 42 is mounted on the outer surface of one side of the mounting frame 41, and there are multiple groups of motors 42. A lead screw 43 is fixedly connected to the output end of the motor 42. Limiting grooves 44 are formed on both sides of the bottom surface of the mounting frame 41, and there are multiple groups of limiting grooves 44. A communication groove is formed inside the middle position of the bottom surface of the mounting frame 41, and the lead screw 43 is inserted into the communication groove, and one end of the lead screw 43 is connected to the inside of the limiting groove 44 by a bearing. This design can drive the lead screw 43 to rotate inside the limiting groove 44 and the communication groove when the motor 42 is started. By starting the four groups of electric telescopic rods 2, the mounting frame 41 can be driven to move upward or downward, so as to facilitate adjusting the height of the mounting frame 41;

[0032] Threaded connection is made between the outer surfaces at both ends of the lead screw 43 and the moving blocks 45, and a spreading plate 46 is fixedly connected to the bottom surface of the moving block 45. The two groups of moving blocks 45 and the spreading plate 46 are opposite to each other, and the internal threads of the two groups of moving blocks 45 threaded to the outer surface parts at both ends of the lead screw 43 are opposite to each other. The outer surface of the upper end of the moving block 45 is snap-fitted into the internal part of the limiting groove 44, and the width dimension of the moving block 45 is adapted to the width dimension inside the limiting groove 44. The angle of the spreading plate 46 is 45 degrees. When the lead screw 43 rotates clockwise, the two groups of moving blocks 45 move synchronously inward inside the limiting groove 44 and drive the two groups of spreading plates 46 to move inward. When the lead screw 43 rotates counterclockwise, the two groups of moving blocks 45 move synchronously outward inside the limiting groove 44 and drive the two groups of spreading plates 46 to move outward. At the same time, the device can limit the moving distance of the moving block 45 and the spreading plate 46 through the limiting groove 44, and the moving length dimension of the moving block 45 and the spreading plate 46 is the same as the length dimension inside the placing groove 33, so as to facilitate spreading the blood sample on the surface of the glass slide through the spreading plate 46;

[0033] The positions of the multiple groups of limiting grooves 44, the moving blocks 45 and the spreading plates 46 correspond to the positions of the multiple groups of placing grooves 33 and the placing blocks 35, thus facilitating spreading the blood sample on the surface of the glass slide through the spreading plate 46.

[0034] Working principle: This device is powered by an external circuit. When the device is in use, first place the supporting bottom plate 1 at an appropriate position, then place the glass slide on the upper surface of the placing block 35 inside the placing groove 33. Subsequently, rotate the threaded rod 36 to drive the ejecting block 34 to move inside the moving groove 32, and lift or lower the placing block 35 through the ejecting block 34. At this time, the height dimension of the placing block 35 can be adjusted according to the actual thickness of the glass slide, so as to support the glass slide through the supporting structure 3. At the same time, multiple glass slides can be placed through the design of the multiple groups of placing grooves 33, and then the blood sample is dropped on the surface of the glass slide;

[0035] When the device is in use, start the four groups of electric telescopic rods 2 to drive the mounting frame 41 to move downward, and make the bottom surface of the spreading plate 46 fit the upper surface of the glass slide. Start the motor 42 to rotate the lead screw 43, and make the two groups of moving blocks 45 and the spreading plate 46 move synchronously inward or outward, and spread the blood sample through the spreading plate 46. When the moving block 45 moves from one end inside the limiting groove 44 to the other end, start the electric telescopic rod 2 to drive the mounting frame 41 to move upward, and reverse the motor 42 to rotate the lead screw 43 in the reverse direction, so that the moving block 45 moves back to one end inside the limiting groove 44, and then repeat the above operation. At this time, the blood sample can be smoothly spread through the spreading structure 4;

[0036] After the blood sample is spread out, a cover glass can be placed on the upper surface of the glass slide to complete the preparation of the smear. Subsequently, the threaded rod 36 is rotated so that the ejecting block 34 pushes the placing block 35 to move upward, and the smear is ejected upward from the inside of the placing groove 33 through the placing block 35, thus facilitating the removal of the prepared smear. The above is the entire working principle of this utility model.
