Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a blood smear apparatus for testing. Background Technology

[0002] Blood smears, prepared by preparing blood samples into thin glass slides for microscopic observation of cell morphology, quantity, and distribution, are a fundamental diagnostic tool for blood disorders. Their functions include: directly identifying abnormalities in red blood cell size and morphology (such as sickle cell anemia); determining white blood cell differential and the presence of abnormal cells; assessing platelet count and aggregation; and dynamically monitoring treatment effects, such as changes in blood cell counts after chemotherapy. The procedure is simple and inexpensive, providing crucial preliminary diagnostic information for clinical practice, particularly significant for emergency and primary care settings.

[0003] In the current use of blood smear devices for laboratory testing, after a patient has their blood drawn, medical staff need to manually spread the blood onto a smear and then observe the blood under a microscope. However, the angle, force, and speed of the smear are all based on the operator's experience, which can easily lead to uneven distribution of the blood film and affect the blood observation results. At the same time, manual smear preparation is time-consuming and inefficient, and is not suitable for use when testing large quantities of blood.

[0004] To address the above issues, a blood smear device for testing was proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a blood smear apparatus for testing, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a smearing mechanism, a hydraulic actuator, a tube inlet, an isolation door, a smearing platform, and a blood pusher plate. The hydraulic actuator is located at the top midpoint of the smearing mechanism. A tube inlet is annularly installed at the edge of the top midpoint of the smearing mechanism. A feeding port for blood testing instruments is provided on the side of the smearing mechanism, and an isolation door is slidably installed on one side of the feeding port. Multiple smearing platforms are installed at the bottom of the smearing mechanism. A blood pusher plate is movably installed inside the smearing mechanism. A push rod is movably connected to the bottom center of the hydraulic actuator, and a device disc with a sliding groove is fixedly connected to the bottom of the push rod. A shovel handle is inserted inside the sliding groove, and a blood pusher plate is fitted to the bottom of the shovel handle. The shovel handle is located inside a gripper, and the gripper is rotatably connected to a central linkage disc via a connecting rod. A gear disc is rotatably installed above the linkage disc.

[0007] The coating platform includes an inner push ring installed at the midpoint of one end. A connecting rod 2 is installed at the midpoint of the inner push ring, and a fixing ring is sleeved on the lower outer side of the connecting rod 2. One side of the fixing ring is fixedly connected to one end of the pressing claw. A pressing base plate is assembled at the bottom of the pressing claw, and a claw support is installed at the bottom of the side away from the midpoint of the pressing claw. A pusher is installed in the groove inside the inner push ring.

[0008] Furthermore, a limit ring is sleeved on the bottom end of the push rod, and the upper midpoint of the gear disk is connected to the bottom of the connecting rod. The connecting rod is connected to the bottom of the push rod, and the linkage disk is movably connected to the gripper through the connecting rod. The gripper is fixedly mounted with a clamping plate on both sides above, and a clamping handle ring is installed inside the gripper. The bottom end of the gripper is obliquely connected to a side push rod.

[0009] Furthermore, guide plates are slidably installed on both sides of the inside of the chute, and telescopic rods are movably connected to both sides of the guide plates. Slide tracks are symmetrically opened on both sides of the chute. The clamping plate is located inside the slide track, and the shovel handle is located in the middle of the guide plate. The gripper is located at the bottom of the chute.

[0010] Furthermore, the blood push plate is fixedly connected to the shovel handle via a rotating ring at the top, and the top two sides of the shovel handle are fixedly equipped with blocks, which slide on both sides above the groove. One end of the side push rod is connected to one side of the shovel handle.

[0011] Furthermore, the glass slide is placed in the groove in the middle of the coating platform, and the coating platform is located above the placement plate, with the surface of the glass slide abutting against the bottom end of the pressing base plate.

[0012] Furthermore, a connecting rod is connected to the midpoint of one end of the coating platform, and one end of the connecting rod abuts against one side of the pusher. A connecting ring is connected to the top of the second connecting rod, and the second connecting rod is movably connected through a telescopic column above the midpoint.

[0013] Furthermore, the tube opening is inserted into the interior of the mounting plate, and the mounting plate is fixedly mounted on the surface of the coating mechanism. A piston ring is movably mounted inside the tube opening, and a device block connected to the push rod is mounted on one side of the piston ring.

[0014] Furthermore, the bottom of the tube opening is conical, and one end of the push rod is located below the equipment disc.

[0015] Furthermore, the blood smear plate is located on one side above the smear platform, and the second connecting rod is located at the midpoint below the push rod, and the pusher moves up and down through the second connecting rod.

[0016] Furthermore, a fixing block is installed at the other end of the pressing claw, and the claw support frame is fixedly connected to one side of the midpoint of the bottom of the pressing claw via a connecting block at one end, and the other end of the claw support frame is movably connected to a fixing ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. During blood smear preparation, the hydraulic pusher moves the entire blood smear plate downwards via the push rod, while the gripper moves horizontally via the rotation of the linkage plate, pushing the blood smear plate horizontally a specified distance above the smear platform. This ensures that the blood on the smear platform is evenly spread over the glass slide. The blood smear plate maintains consistent pressure during smear preparation, preventing uneven pressure that could lead to excessively thick or thin blood films in certain areas. This ensures consistent cell dispersion, improves the accuracy of microscopic observation, and avoids cell compression or rupture due to uneven pressure, maintaining the cells' natural state. Furthermore, the synchronous pushing of the blood smear plate by the linkage plate and gripper improves the efficiency of blood smear preparation, making it suitable for batch blood testing.

[0019] 2. During blood smear preparation, when fixing the slide, the pressing claw descends synchronously with the equipment disk via the linkage shaft two to press and fix one side of the slide above the smear platform. This prevents the slide from shifting when pushed, allowing for more precise control of the angle and force of the slide pusher. It also prevents the blood trajectory above the slide from deviating, and the smear platform moves up and down via the pusher to automatically enter and exit the smear mechanism. The isolation door isolates the inside of the smear mechanism, ensuring the safety and quality of the blood sample, maintaining the blood sample in a physiological state, and avoiding testing errors.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] The purpose of this embodiment is to provide a blood smear device for testing, including a smear mechanism 1, a hydraulic actuator 2, a tube opening 3, an isolation door 4, a smear platform 5, and a blood push plate 6. The hydraulic actuator 2 is located at the top midpoint of the smear mechanism 1. A push rod 21 is movably connected to the bottom center of the hydraulic actuator 2, and a device disk 23 with a sliding groove 24 is fixedly connected to the bottom of the push rod 21. The shovel handle 62 is located inside the gripper 27, and the gripper 27 is rotatably connected to the intermediate linkage disk 25 through a connecting rod 26. A gear disk 28 is rotatably mounted above the linkage disk 25.

[0034] In this invention, the bottom end of the push rod 21 is fitted with a limit ring 22, and the upper midpoint of the gear disk 28 is connected to the bottom of the connecting rod 29. The connecting rod 29 is connected to the bottom of the push rod 21, and the linkage disk 25 is movably connected to the gripper 27 through the connecting rod 26. The gripper 27 is fixedly equipped with a clamping plate 212 on both sides above, and a clamping handle ring 210 is installed inside the gripper 27. The bottom end of the gripper 27 is obliquely connected to a side push rod 211.

[0035] For details, please refer to the following: Figure 4 and Figure 6 As shown, guide plates 2401 are slidably installed on both sides of the inside of the chute 24, and telescopic rods 2402 are movably connected to both sides of the guide plates 2401. Slide tracks 2403 are symmetrically opened on both sides of the chute 24. The clamping plate 212 is located inside the slide track 2403, and the shovel handle 62 is located in the middle of the guide plate 2401. The gripper 27 is located at the bottom of the chute 24.

[0036] In the above invention, the blood smear plate 6 is driven by the hydraulic pusher 2 to move the push rod 21 up and down. When the blood smear plate 6 moves down, the shovel handle 62 is located on one side of the gripper 27. The gripper 27 drives the connecting rod 26 to rotate and move horizontally at the bottom of the slide groove 24 through the linkage disc 25, pushing the blood smear plate 6 to one side to a specified distance, so that the blood can be evenly smeared. During the smearing process, the gripper 27 is pushed by the linkage disc 25, which can keep the smearing force and angle consistent, and can prevent cell damage during the smearing process. Moreover, multiple sets of blood smear plates 6 are pushed synchronously by the gripper 27, which is suitable for large-scale hospitals or hospitals with large blood testing volumes, and can reduce the waiting time for patients to get blood results.

[0037] For details, please refer to the following: Figure 9 and Figure 10 As shown, a tube opening 3 is annularly installed at the midpoint edge of the top of the coating mechanism 1. The tube opening 3 is inserted into the interior of the mounting plate 31, and the mounting plate 31 is fixedly installed on the surface of the coating mechanism 1. A piston ring 32 is movably installed inside the tube opening 3, and a device block 33 connected to the push rod 34 is installed on one side of the piston ring 32.

[0038] In this invention, the bottom of the tube opening 3 is conical, and one end of the push rod 34 is located below the equipment disk 23.

[0039] In the above invention, the extracted blood is poured into the inside of the tube opening 3. When the piston ring 32 inside the tube opening 3 descends through the device disc 23, it squeezes the push rod 34, causing the blood to drip in the tube opening 3 in the form of water droplets onto the glass slide. This ensures that the amount of blood tested each time is consistent, avoids blood waste, and the remaining blood can be used for other tests or for comparison of multiple tests, thereby improving the accuracy of blood testing.

[0040] For details, please refer to the following: Figure 7 and Figure 8 As shown, the side of the smear mechanism 1 has a feeding port for blood testing instruments, and an isolation door 4 is slidably installed on one side of the feeding port. Multiple smear platforms 5 are installed at the bottom of the smear mechanism 1. Each smear platform 5 includes an inner push ring 52 installed at the midpoint of one end. A connecting rod 53 is installed at the midpoint of the inner push ring 52. A fixing ring 56 is sleeved on the lower part of the outer side of the connecting rod 53. One side of the fixing ring 56 is fixedly connected to one end of the pressing claw 5602. A pressing base plate 5603 is assembled at the bottom of the pressing claw 5602. A claw bracket 5604 is installed on the bottom side of the side away from the midpoint of the pressing claw 5602. A pusher 57 is installed in the groove inside the inner push ring 52.

[0041] In this invention, the glass slide is placed in the groove in the middle of the coating platform 5, and the coating platform 5 is located above the placement plate 51. The surface of the glass slide abuts against the bottom end of the pressing base plate 5603. A connecting rod 58 is connected to the midpoint of one end of the coating platform 5, and one end of the connecting rod 58 abuts against one side of the pusher 57. A connecting ring 54 is connected to the top of the connecting rod 53, and the connecting rod 53 is movably connected through the telescopic column 55 above the midpoint.

[0042] For details, please refer to the following: Figure 8 As shown, the blood smear plate 6 is located on one side above the smear platform 5, and the connecting rod 2 53 is located at the midpoint below the push rod 21. The pusher 57 moves up and down through the connecting rod 2 53. The other end of the pressing claw 5602 is equipped with a fixing block 5601, and the claw support 5604 is fixedly connected to the midpoint of the bottom of the pressing claw 5602 through a connecting block 5605 at one end. The other end of the claw support 5604 is movably connected to the fixing ring 56.

[0043] In the above invention, the second connecting rod 53 descends synchronously through the device disk 23. The descent of the second connecting rod 53 causes the pusher 57 to move up and down. One side of the pusher 57 is inclined. The smear platform 5 can move horizontally at the bottom of the smear mechanism 1 through the change of the edge angle of the pusher 57, so that the smear platform 5 can extend and retract inside the smear mechanism 1. The extended smear platform 5 makes it easier for medical personnel to place the glass slide inside the groove, so that the blood pusher plate 6 can test the blood slide in a sterile environment, thereby improving the accuracy of the blood test results. The descent of the second connecting rod 53 can also cause the pressing claw 5602 to descend synchronously. The pressing base plate 5603 fixes one side of the glass slide, preventing the glass slide from shifting when the blood pusher plate 6 pushes the slide.

[0044] For details, please refer to the following: Figure 3 As shown, a blood smear plate 6 is movably installed inside the smear mechanism 1. A shovel handle 62 is inserted inside the slide groove 24, and the blood smear plate 6 is mounted at the bottom of the shovel handle 62. The blood smear plate 6 is fixedly connected to the shovel handle 62 via a rotating ring 61 at the top. Stop blocks 63 are fixedly mounted on both sides of the top of the shovel handle 62, and the stop blocks 63 slide on both sides above the slide groove 24. One end of the side push rod 211 is connected to one side of the shovel handle 62.

[0045] In the above invention, the blood slide pusher 6 is placed at a certain angle. The angle of inclination allows the device to push the slide with less effort and more even force. The shovel handle 62 is located inside the slide groove 24. The limiting setting of the slide groove 24 ensures that the blood slide pusher 6 can only move horizontally along the slide groove 24, which can push the blood above the glass slide. The shovel handle 62 is pushed by the gripper 27 and the side push rod 211 to keep the force of the blood slide pusher 6 consistent when pushing the slide.

[0046] In summary, the working principle of this invention is as follows: A clean glass slide is placed in the groove on the surface of the smearing platform 5. After placement, the smearing platform 5 is moved and extended by the pusher 57 to the inside of the smearing platform 5. The blood to be tested is poured into the inside of the tube opening 3. At this time, the hydraulic pusher 2 uses its internal mechanical energy to push the push rod 21. When the push rod 21 descends, it simultaneously causes the equipment disk 23 and the connecting rod 2 53 to descend. When the equipment disk 23 descends, it causes the push rod 34 to press down and descend. The push rod 34 drives the piston ring 32 inside the tube opening 3 to descend, thus lowering the tube opening. 3. The blood inside is squeezed out from the bottom outlet. At the same time, the descent of the connecting rod 53 drives the pressing claw 5602 and the pusher 57 to descend synchronously. The smear platform 5 abuts against one end of the pusher 57 through the connecting rod 58. One side of the smear platform 5 is close to the midpoint of the smear mechanism 1. At this time, the blood is in the shape of a water droplet above the glass slide, waiting for subsequent slide pushing and detection. At the same time, the upper side of the glass slide is pressed and fixed by the pressing claw 5602. With the setting of the groove inside the smear platform 5, the glass slide can be prevented from shifting, and the blood pushing plate 6 can more accurately control the pushing force.

[0047] After the slide is fixed, the blood slide pusher 6 descends together with the equipment disk 23 and is located on one side of the surface of the smearing platform 5. The blood slide pusher 6 is installed inside the slide groove 24 via the shovel handle 62. The guide plate 2401 inside the slide groove 24 fixes the two sides of the shovel handle 62. The guide plate 2401 is displaced by the telescopic rod 2402 to ensure that the shovel handle 62 and the blood slide pusher 6 move smoothly. A linkage disk 25 is installed at the bottom center of the equipment disk 23. The linkage disk 25 is rotated by the rotation of the connecting shaft 29, which drives the gear disk 28 to rotate, causing the linkage disk 25 to drive the connecting rod 26 and the gripper 27 to move. The gripper 27 moves horizontally inside the slide 2403 via the clamping plate 212 to push the blood slide pusher 6 on one side. The blood slide pusher 6 moves at a uniform speed above the slide under force, so that the blood above the slide is evenly smeared. The blood thickness of the evenly pushed slide is uniform, and the quality of the blood film is more stable.

[0048] Finally, the gripper 27 retracts via the hydraulic pusher 2, causing the connecting rod 29 to rotate in the opposite direction, which in turn causes the connecting rod 26 to rotate in the opposite direction and retract. The gripper 27 then uses the internal retaining ring 210 to bring back the blood slide plate 6, which has been pushed a certain distance. As the hydraulic pusher 2 retracts, the pressing base plate 5603, the pusher 57, and the blood slide plate 6 rise synchronously. The blood slide plate 6 and the pressing base plate 5603 release the slide from the glass slide. The glass slide moves to one side via the smearing platform 5, which moves along the edge of the pusher 57, and is discharged from the feeding port on the side of the smearing mechanism 1. Medical personnel then remove the glass slide for testing.
