Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a device and a method for making thick and thin blood films in one piece. Background Art

[0002] Blood film, also known as blood test smear, is also referred to as blood smear or blood film. Microscopic examination of blood test smear is a basic method of blood cytology examination and is widely used, especially for the diagnosis of various blood diseases and parasites. However, poor preparation and staining of blood smears often make cell identification difficult and even lead to wrong conclusions. In order to more directly observe the situation of white blood cells and red blood cells in blood samples, some blood film films use thick and thin blood films on the same slide, and the slide is evenly divided into six grid areas. Thick blood film: Dip 4-5μL of blood sample (the size of a millet grain) with one corner of the pusher, place it in the center of the third grid on the slide, and rotate the pusher from the inside to the outside in one direction to make a circular thick blood film with a diameter of 0.8-1.0cm; thin blood film: Dip 1-1.5μL of blood sample with one corner of the pusher, place it on the right side of the fourth grid on the slide, and push it to the left at a constant speed of 25-35 degrees to form a 2.0-2.5cm tongue-shaped thin blood film.

[0003] At present, blood smears are mostly made manually by medical staff step by step. During the whole process, the slide needs to be taken repeatedly, which is not only cumbersome but also easy to wear or break. When using a pusher to push the blood droplets onto the slide, it is easy for unfamiliar medical staff to make the blood unevenly smeared, resulting in inaccurate observation results. Although the existing smearer or rapid smearing device can increase the speed of blood smear production, it cannot make the blood sample in the form of thick blood film and thin blood film on the same slide, and most devices cannot adjust the angle between the pusher and the slide during smearing. Summary of the invention

[0004] In order to solve the above problems, reduce the difficulty of preparing blood film slices, and improve the quality of blood film slice production, the present invention proposes a device and method for preparing thick and thin blood film slices. The surface of the cleaned and disinfected slide is divided into six areas and loaded into a slide fixing groove fixed on a circular ring frame. When a blood film slice needs to be prepared, the blood sample is first dripped into a fine funnel and a coarse funnel respectively, and then the circular ring frame is driven by an active wheel to rotate the slide fixing groove, thereby rotating one end of the slide to the slide moving frame, and at the same time, the active wheel drives a pushing plate to push the slide from the slide moving frame into the slide moving frame and fix it, and then a screw rod is used to make the slide moving frame move horizontally at a uniform speed, and during the movement, the triangular convex key and the straight funnel are connected. The vertical movable rod of the rack cooperates to swing the thin funnel at the lower end of the straight funnel rack to contact the glass slide, so that the blood sample remains on the glass slide. Then, the linear slide pusher rack is controlled to move downward when the glass slide moves, so that the straight push glass slide contacts the blood and the blood is evenly smeared on the glass slide to form a thin blood film when the straight push glass slide and the glass slide move relative to each other. Thereafter, the thick funnel at the lower end of the bent funnel rack is swung to contact the empty glass slide at the front end of the thin blood film through the triangular convex key and the vertical movable rod of the bent funnel rack. When the slide pick moves to the bottom of the rotating slide pusher rack, the rotating slide pusher rack drives the rotating slide pusher rack to move downward to contact the blood sample left by the thick funnel. At this time, the screw rod part has no thread, and the glass slide stops moving, which is convenient for the rotating slide pusher to rotate and smear the blood sample into a thick blood film.

[0005] In order to achieve the above technical objectives, the technical solution of the present invention is as follows:

[0006] A device for making thick and thin blood films in one piece, comprising a base;

[0008] The middle parts of the front ends of the left support plate and the right support plate are commonly connected with a long crossbeam frame, a symmetrical slide groove in the front-back direction is provided in the middle part of the long crossbeam frame, a slide moving frame is installed in the symmetrical slide groove, a threaded hole parallel to the symmetrical slide groove is provided in the lower part of the slide moving frame, a second motor is installed at the front end of the long crossbeam frame, a screw rod is coaxially connected to the output end of the second motor, and the other end of the screw rod is sleeved in the threaded hole of the slide moving frame;

[0009] The front ends of the left and right support plates are located above the long cross beam frame and are connected to a short cross beam frame together. Two rotating shafts are installed above the short cross beam frame through bearings, wherein a straight funnel frame is sleeved on the front rotating shaft, and a bent funnel frame is sleeved on the rear rotating shaft. The upper ends of the two funnel frames are clamped, and vertical movable rods are installed on the left front sides corresponding to the two rotating shafts through sliding slots. The upper ends of the two vertical movable rods are respectively in contact with the upper ends of the straight funnel frame and the bent funnel frame. A linear sheet pusher frame is installed on the left side of the short cross beam frame between the two rotating shafts, and an arc slide groove is connected to the middle of the linear sheet pusher frame. The arc slide groove is installed through a sliding frame There is a straight glass slide, and a rotating film pushing frame is installed on the left side of the short beam frame in front of the bent funnel frame. A third motor with a vertical rotating shaft and an output end facing downward is installed in the middle of the rotating film pushing frame, and a clamping block is installed at the output end of the third motor, and a rotating glass slide is clamped on the clamping block. Two pairs of left-right symmetrical rectangular holes are opened on the lower side of the symmetrical slide groove of the long beam frame, wherein the front rectangular hole position coincides with the straight film pushing frame, and the rear rectangular hole coincides with the rotating film pushing frame, and semicircular convex keys are installed at the corresponding rectangular holes at the lower ends of the straight film pushing frame and the rotating film pushing frame, and when the slide moving frame moves to the semicircular convex key, the semicircular convex key can be pressed down to make the slide pushing frame move downward.

[0010] Furthermore, the first motor is controlled by a contactor with a contact switch or a travel switch, so that the first motor can rotate only one circle at a time when started;

[0011] The second motor is provided with a speed regulating switch for control, and the speed of the second motor can be adjusted as required;

[0012] The third motor is provided with a speed regulating switch for control, and the speed of the third motor can be adjusted as required;

[0013] The inside of the glass slide fixing groove is the same width as the glass slide, has a larger thickness, is through-through from front to back, and has a width smaller than the glass slide at one end facing the inner side of the circular ring frame, so that the glass slide can be fixed inside and can be pushed outward after being subjected to force;

[0014] The upper side of the slide moving rack is provided with a groove larger than the width of the slide, which can be used to place the slide flat, and the rear half of both sides of the groove on the slide moving rack are provided with rear slots, in which the slide can be fixed;

[0015] Each groove on the groove wheel is distributed on the line connecting the midpoint of the line connecting the two slide fixing grooves and the center of the circle. When the driving wheel rotates one circle, the protruding teeth control the groove wheel to rotate, and the rotation arc is equal to the angle between the two grooves. At this time, the slide fixing grooves on the circular frame rotate the same arc and the frontmost slide fixing groove is parallel to the slide moving frame.

[0016] The angle between the line connecting the eccentric column installation point on the driving wheel and the center of the circle and the line connecting the protruding tooth and the center of the circle is half of the angle between the line connecting the two grooves on the groove wheel and the center of the circle, and when the protruding tooth and the groove are in the process of contacting and disengaging, the driving wheel drives the pushing plate to be farthest away from the glass slide fixing groove, and when the driving wheel continues to rotate and the groove wheel stops rotating, the driving wheel drives the pushing plate to push the glass slide in the glass slide fixing groove out of the glass slide fixing groove;

[0017] A moving block is installed on the left side of the slide moving frame, and the moving block contacts the side of the long beam frame to prevent the slide moving frame from deflecting when it moves. A triangular convex key is provided on the top of the moving block. When the slide moving frame moves to the bottom of the vertical movable rod, the triangular convex key contacts the vertical movable rod and further pushes the vertical movable rod upward, so that the vertical movable rod controls the straight funnel frame or the bent funnel frame to swing, so that the lower end of the thick funnel or the thin funnel contacts the slide, and the blood sample is left on the slide.

[0018] The inner diameter of the lower outlet of the thin funnel is relatively small, and the inner diameter of the lower outlet of the thick funnel is relatively large, so as to facilitate the control of the thickness of the blood film remaining on the glass slide;

[0019] When the glass slide is fixed on the glass slide moving rack, the tip of the triangular convex key corresponds to the third grid of the glass slide, so that the lower end of the thin funnel on the straight funnel rack contacts the right area of ​​the fourth grid of the glass slide. At the same time, due to the curved shape of the bent funnel rack, when the lower end of the thick funnel on the bent funnel rack contacts the glass slide, the contact point of the lower end of the thick funnel is at the center of the third grid on the glass slide, thereby achieving the purpose of dipping different volumes of blood pressure samples at different positions on the glass slide;

[0020] The straight-push glass slide can change the angle between the straight-push glass slide and the horizontal plane by changing the position of the sliding frame connected thereto in the arc-shaped sliding groove, and the lower end surface of the straight-push glass slide is always kept in the same position;

[0021] When the slide moving frame moves to the bottom of the linear slide push frame, the contact point of the slide moving frame and the highest point of the semicircular convex key on the linear slide push frame is in the same vertical plane as the vertex of the triangular convex key at this time, so that when the slide pick moves to the bottom of the linear slide push frame with the blood drop, the linear slide push frame is just pulled downward so that the lower end surface of the linear slide is in contact with the blood on the slide and the blood drop is further smeared on the fourth grid and the rear half of the slide to form a tongue-shaped thin blood film;

[0022] When the slide moving frame moves to the bottom of the rotating slide pusher frame, the contact point of the slide moving frame and the highest point of the semicircular convex key on the rotating slide pusher frame is in the same vertical plane as the vertex of the triangular convex key at this time, so that when the slide moves to the bottom of the rotating slide pusher frame with the blood drop, the rotating slide pusher frame is just pulled downward, so that the lower end surface of the rotating slide pusher contacts the blood on the slide and the blood drop is rotated and smeared on the third grid on the slide under the drive of the third motor to form a circular thick blood film;

[0023] A vertical first spring is installed between the linear push-piece frame and the long beam frame, and a vertical second spring is installed between the rotating push-piece frame and the long beam;

[0024] The front end of the screw rod is located below the rotating push glass slide and has no thread, so that when the slide moving frame moves to the bottom of the rotating push glass slide, the rotating push glass slide stops moving when it contacts the slide slide, which is convenient for rotating the push glass slide to rotate and smear the blood sample on the slide glass;

[0025] A fixing plate is installed above the connection between the screw rod and the second motor, the rear half of the fixing plate is equal to the width and thickness of the glass slide, and is slightly longer than the rear card slot, so that the glass slide can be pushed out of the rear card slot;

[0026] The sides of the left supporting plate and the right supporting plate are jointly covered with a dustproof cover shell and are provided with a slide loading port, through which the cleaned, sterilized and dried slides can be loaded into the slide fixing groove.

[0027] The present invention also provides a method for using the thick and thin blood film production device, comprising the following steps:

[0028] S1: Loading slides; soak several slides in cleaning solution or 10% hydrochloric acid for 24 hours, then thoroughly clean and dry them, insert the slides into the slide fixing grooves from the loading port and fix them until there are slides in all the slide fixing grooves.

[0029] S2: Collect blood samples; collect the blood samples to be tested and drip them into the fine funnel and the coarse funnel respectively after processing.

[0030] S3: Install the push glass slide; disinfect the straight push glass slide and the rotating push glass slide in the same disinfection method as the slide glass and wipe them dry, then clamp the straight push glass slide on the sliding frame on the arc slide, adjust the position of the sliding frame in the arc slide according to the specific concentration of the blood sample, so as to adjust the angle of the straight push glass slide to an appropriate size, and clamp the rotating push glass slide on the card block.

[0031] S4: Output the slide; check the slide moving rack to ensure that it is at the end of the symmetrical slide slot, first start the first motor, the first motor controls the driving wheel to rotate one circle and then stop, at which time the slide is transferred from the slide fixing slot to the slide moving rack.

[0032] S5: smearing a blood film; first start the third motor to slowly rotate the rotating slide pusher, then start the second motor, the second motor controls the screw rod to rotate and move the slide moving frame along the symmetrical slide groove, during the movement, first smear a thin blood film on the slide through the linear slide pusher, and then smear a thick blood film through the rotating slide pusher.

[0033] S6: Remove the slide; when the slide moving frame moves out of the threaded part of the screw rod, move the slide moving frame to the front end until the fixed plate pushes out the smeared slide, then the slide can be removed to complete the preparation.

[0034] Beneficial effects of the present invention:

[0035] 1. Compared with the prior art, the present invention can realize the same-piece production of thick blood film and thin blood film of blood samples. Through the straight funnel stand and the bent funnel stand and the matching thin funnel and thick funnel, blood samples of different volumes can be dipped on the glass slide, and the sampling can be kept the same each time, so that the thickness of the thick and thin blood films applied each time is consistent, which is convenient for observation and comparison;

[0036] 2. The device can smear the blood sample on the glass slide more evenly. The second motor keeps the glass slide moving at a constant speed during the smearing process, and the third motor controls the push glass slide to rotate at a constant speed, which greatly improves the stability of the smearing process. When the hematocrit changes, the device can adjust the angle between the push glass slide and the glass slide, making the inspection effect of the thin blood film more accurate.

DETAILED DESCRIPTION

[0051] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0052] Example 1

[0053] See also Figures 1 to 11The invention discloses a device for making thick and thin blood films, comprising a base 1;

[0054] A symmetrical left support plate 3 and a right support plate 2 are installed at the upper rear of the base 1. The sides of the left and right support halves are covered with a dust cover and provided with a loading port 6, through which the cleaned, disinfected and dried slides can be loaded into the slide fixing groove 21. A hole is opened in the middle of the right support plate 2 and a motor bracket 7 is installed on the lower right side of the hole. A first motor 8 is installed on the motor bracket 7. The first motor 8 is controlled by a contactor and has a contact switch or a travel switch. After starting, the first motor 8 only rotates one circle. The output end of the first motor 8 is coaxially connected to a driving wheel 9, and a protruding tooth 901 is installed on the side of the driving wheel 9.

[0055] A turntable 19 is installed in the middle of the left support plate 3 through a bearing. The center of the turntable 19 is on the same horizontal plane as the center of the driving wheel 9. A circular frame 20 is installed on the inner side of the turntable 19 through four connecting rods 1901. Twelve centrally symmetrical slide fixing grooves 21 are installed on the circular frame 20. The inside of the slide fixing groove 21 is the same width as the slide and has a larger thickness. It is through the front and back and the width of one end toward the inner side of the circular frame 20 is smaller than the slide, so that the slide can be fixed inside. The inner center of the turntable 19 is connected to the shaft 22 A groove wheel 23 is coaxially installed through the hole of the right support plate 2, and twelve grooves 2301 are opened on the groove wheel 23. Each groove 2301 is distributed on the line connecting the midpoint of the line connecting the two slide fixing grooves 21 and the center of the circle. When the driving wheel 9 rotates one circle, the protruding tooth 901 controls the groove wheel 23 to rotate, and the rotation arc is equal to the angle between the two grooves 2301. At this time, the slide fixing grooves 21 located on the circular frame 20 rotate the same arc and the frontmost slide fixing groove 21 is parallel to the slide moving frame 27.

[0056] An eccentric column 24 is installed on the driving wheel 9 on a side corresponding to the right support plate 2, and a connecting rod 25 is sleeved on the eccentric column 24. A smooth groove 201 in the same plane as the axis of the driving wheel 9 is provided on the right support plate 2. A push plate 26 is installed in the smooth groove 201, and the tail of the push plate 26 is sleeved with the other end of the connecting rod 25. The angle between the line from the installation point of the eccentric column 24 to the center of the circle and the line from the protruding tooth 901 to the center of the circle is half the angle between the two grooves 2301 provided on the groove wheel 23 and the center of the circle. When the protruding tooth 901 and the groove 2301 are in the process of contacting and disengaging, the driving wheel 9 drives the push plate 26 to be farthest from the slide fixing groove 21, and when the driving wheel 9 continues to rotate and the groove wheel 23 stops rotating, the driving wheel 9 drives the push plate 26 to push the slide in the slide fixing groove 21 out of the slide fixing groove 21.

[0057] The left support plate 3 and the right support plate 2 are connected to a long crossbeam frame 4 at the middle of the front end. A symmetrical slide groove 401 is provided in the middle of the long crossbeam frame 4 in the front-to-back direction. A slide moving frame 27 is installed in the symmetrical slide groove 401. A groove larger than the width of the slide is provided on the upper side of the slide moving frame 27, so that the slide can be placed flat. Rear card grooves 2701 are provided on both sides of the rear half of the upper groove of the slide moving frame 27, and the slide can be fixed in the rear card groove 2701. A threaded hole 2701 parallel to the symmetrical slide groove 401 is provided at the lower part of the slide moving frame 27. 2. A second motor 18 is installed at the front end of the long crossbeam frame 4. The second motor 18 is controlled by a speed regulating switch. The speed of the second motor 18 can be adjusted as needed. A screw rod 29 is coaxially connected to the output end of the second motor 18. The other end of the screw rod 29 is sleeved in the threaded hole 2702 of the slide moving frame 27. The second motor 18 drives the screw rod 29 to rotate, so that the slide moving frame 27 can move forward and backward along the screw rod 29. The speed of the second motor 18 can be changed according to the specific situation of the blood sample to adjust the speed of the slide movement.

[0058] The left support plate 3 and the right support plate base; the front end of the left support plate 2 is located above the long cross beam frame 4 and is connected to a short cross beam frame 5. Two rotating shafts 10 are installed above the short cross beam frame 5 through bearings, wherein a straight funnel frame 11 is sleeved on the front rotating shaft 10, and a bent funnel frame 30 is sleeved on the rear rotating shaft 10, and the upper ends of the two funnel frames are in a clamp shape; the left front side of the short cross beam frame 5 corresponding to the two rotating shafts 10 is installed with a vertical movable rod 12 through a sliding slot 501 The upper ends of the two vertical movable rods 12 are respectively in contact with the upper ends of the straight funnel frame 11 and the bent funnel frame 30, and the straight funnel frame 11 or the bent funnel frame 30 can be driven to swing through the up and down movement of the short crossbeam frame 5. A straight film push frame 13 is installed between the two rotating shafts 10 on the left side of the short crossbeam frame 5. An arc-shaped slide 14 is connected to the middle of the straight film push frame 13. A straight glass slide 15 is installed in the arc-shaped slide 14 through a sliding frame 1401. The straight film push frame 13 and A vertical first spring 16 is installed between the long beam frames 4; a rotating film pusher frame 31 is installed on the left side of the short beam frame 5 in front of the bending funnel frame 30, and a third motor 32 with a vertical rotating shaft and an output end downward is installed in the middle of the rotating film pusher frame 31, and a clamping block 33 is installed at the output end of the third motor 32, and a rotating glass pusher 34 is clamped on the clamping block 33. Two pairs of left-right symmetrical rectangular holes 402 are opened on the lower side of the symmetrical slide 401 of the long beam frame 4, of which the front side is provided with a plurality of holes 402. The rectangular hole 402 at the front coincides with the linear film pusher 13, and the rear rectangular hole 402 coincides with the rotating film pusher 31, and semicircular convex keys 1301 are installed at the corresponding rectangular holes 402 at the lower ends of the linear film pusher 13 and the rotating film pusher 31, and a vertical second spring 35 is installed between the rotating film pusher 31 and the long beam frame 4; when the slide moving frame 27 moves to the semicircular convex key 1301, the semicircular convex key 1301 can be pressed down to make the two film pushers move downward.

[0059] When the slide moving frame 27 first moves to the bottom of the vertical movable rod 12 next to the fine funnel 1101, the vertical movable rod 12 is pushed upward so that the straight funnel frame 11 swings and just contacts the front end of the fine funnel 1101 to the right side of the fourth grid of the slide, leaving about 1 to 1.5 μL of blood on the slide. When the slide moving frame 27 moves to the bottom of the linear push frame 13, the contact point when the slide moving frame 27 contacts the highest point of the semicircular convex key 1301 on the linear push frame 13 is in the same vertical plane as the vertex of the triangular convex key 2801 at this time, so that when the slide pick moves to the bottom of the linear push frame 13 with the blood drop, the linear push frame 13 is just pulled downward so that the lower end surface of the straight push glass slide 15 contacts the blood on the slide and further smears the blood droplets on the fourth grid and the second half of the slide to form a tongue-shaped thin blood film with a length of 2.0 to 2.5 cm.

[0060] The glass slide coated with a thin blood film continues to move to the bottom of the vertical movable rod 12 next to the coarse funnel 3001. The vertical movable rod 12 is pushed upward so that the bent funnel frame 30 swings just to make the front end of the coarse funnel 3001 contact the middle of the third grid of the glass slide, leaving about 4 to 5 μL of blood on the glass slide. When it continues to move to the bottom of the rotating slide pusher frame 31, the front end of the screw rod 29 is located below the rotating slide pusher 34 without threads, so that when the slide moving frame 27 moves to the bottom of the rotating slide pusher, the rotating slide pusher 34 stops when it contacts the slide pick. The slide moving frame 27 stops moving, and the contact point when the highest point of the semicircular convex key 1301 on the rotating slide pushing frame 31 contacts is in the same vertical plane as the vertex of the triangular convex key 2801 at this time, so that when the slide with the blood drop moves to the bottom of the rotating slide pushing frame 31, the rotating slide pushing frame 31 is just pulled downward, so that the lower end surface of the rotating slide pushing frame 34 contacts the blood on the slide and is driven by the third motor 32 to rotate and smear the blood drop on the third grid on the slide to form a circular thick blood film with a diameter of 0.8 to 1.0 cm.

[0061] A fixing plate 17 is installed above the connection of the second motor 18. The rear half of the fixing plate 17 is equal in width and thickness to the glass slide, and is slightly longer than the rear slot 2701. When the glass slide moving frame 27 moves to the front end of the fixing plate 17, the fixing plate 17 can push the glass slide out of the rear slot 2701 for easy removal.

[0062] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the invention to only the specific embodiments described. Obviously, many modifications and changes can be made according to the content of this specification.
