Description

Technical Field

[0001] This utility model belongs to the field of malaria blood smear technology, and in particular relates to an automatic staining device for malaria blood smears. Background Technology

[0002] The automated malaria blood smear staining device is an automated device specifically designed for the rapid and accurate staining of malaria blood smears. Its main purpose is to improve the efficiency of malaria diagnosis and avoid errors in manual operation. Especially in large-scale testing, this device can complete complex staining procedures in a short time, thereby helping medical personnel to quickly determine whether there is a malaria parasite infection.

[0003] According to a public disclosure of an automatic blood smear staining device for malaria (Publication No.: CN219224318U), the blood smear staining instrument has a staining tank inside. A reagent placement platform is provided on one side of the blood smear staining instrument. A methanol storage bottle, a dye mother liquor bottle, and a diluent bottle are provided on the reagent placement platform. The methanol storage bottle, dye mother liquor bottle, and diluent bottle are all connected to the staining tank. A blood smear placement assembly is placed in the staining tank. The blood smear placement assembly can place multiple sets of blood smears at the same time, and the multiple sets of blood smears are placed in the blood smear placement assembly with the thick blood film on them at a higher position and the thin blood film at a lower position.

[0004] In the aforementioned application, although the blood smear staining instrument and staining tank assembly can be precisely matched to perform staining operations on multiple malaria blood smears at the same time, this design still cannot clean the staining tank after use, which may result in staining residue inside the staining tank, thereby affecting or contaminating subsequent experiments. Therefore, we propose an automatic staining device for malaria blood smears. Utility Model Content

[0005] The purpose of this invention is to provide an automatic staining device for malaria blood smears. Through the design of components such as the motor, cleaning box, and water spray plate of the cleaning mechanism, it solves the problems of low efficiency, cumbersome operation, and uneven cleaning of the staining tank in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an automatic staining device for malaria blood smears, comprising a smear stainer, a display screen and a reagent placement platform on the side of the smear stainer, a staining tank on the top of the smear stainer, and a cleaning mechanism inside the smear stainer. The cleaning mechanism includes a power chamber located inside the cleaning mechanism, a motor fixedly connected inside the power chamber, a rotating shaft fixedly connected to the output shaft of the motor, a push turntable fixedly connected to the circumference of the rotating shaft, a cleaning box fixedly connected inside the power chamber, a squeezing plate slidably connected inside the cleaning box, a force rod fixedly connected to the side of the squeezing plate, the side of the force rod penetrating and slidably connected to the side of the cleaning box, a delivery hose fixedly penetrating the side of the cleaning box, and a water spray plate fixedly connected to the end of the delivery hose away from the cleaning box. The purpose of this device is to ensure that the staining tank is automatically cleaned after the staining solution is used, avoiding staining residue from contaminating subsequent experiments.

[0007] Furthermore, the circumferential surface of the rotating shaft is provided with a threaded groove, and the rotating shaft is threadedly connected to a threaded sleeve through the threaded groove. One end of the water spray plate is fixedly connected to the top of the threaded sleeve, and the side of the threaded sleeve is slidably connected to the inner wall of the power compartment. The purpose of this is to ensure that the water spray plate can move during use, not limited to a local position.

[0008] Furthermore, a return spring is fixedly connected inside the cleaning box. The end of the return spring away from the inside of the cleaning box is fixedly connected to the side of the extrusion plate. The purpose of this is to ensure that the extrusion plate can automatically reset and reduce manual intervention.

[0009] Furthermore, the end of the force-bearing rod away from the cleaning box is located on the displacement trajectory of the drive turntable, and the initial position of the water spray plate is located inside the power chamber. The purpose of this is to ensure that one end of the force-bearing rod can be pushed during the rotation of the drive turntable.

[0010] Furthermore, the smear staining apparatus is internally equipped with a drying mechanism, which includes a pulley one fixedly connected to the end of the rotating shaft away from the motor output shaft. A belt is provided on the circumferential surface of the pulley one. A ventilation opening is provided on the side of the smear staining apparatus. A support shaft is rotatably connected through the ventilation opening. A pulley two is fixedly connected to one end of the support shaft that passes through the ventilation opening. The pulley one is connected to the pulley two via a belt. Suction blades are fixedly connected to the circumferential surface of the support shaft. A guide groove is provided inside the ventilation opening, and an air blowing port is provided inside the guide groove. The purpose of this is to air dry the cleaned staining tank, accelerate the water loss rate, and reduce waiting time.

[0011] Furthermore, the number of suction blades is set to several and arranged in a circumferential array along the circumference of the support axis. A dustproof plate is provided inside the vent to ensure sufficient airflow while preventing debris from entering the vent.

[0012] Furthermore, the number of air outlets is set to several and evenly distributed inside the guide groove. The purpose is to achieve uniform airflow distribution, improve airflow efficiency, and ensure that the airflow can effectively cover the entire area.

[0013] This utility model has the following beneficial effects: This invention utilizes the coordinated operation of components such as the motor, cleaning chamber, and spray plate in the cleaning mechanism. After the smear stainer completes the staining of the malaria blood smear, the motor is activated to drive the rotating shaft to rotate, which in turn drives the rotating disc to rotate. The protrusions on the rotating disc push the force rod, thereby causing the extrusion plate to move within the cleaning chamber. This generates extrusion force, causing water to flow into the delivery hose and be sprayed out through the spray plate. Simultaneously, the rotating shaft drives the threaded sleeve to move linearly within the power chamber through the threaded groove, causing the spray plate to move along the inside of the staining tank to complete the rinsing. This design achieves automated cleaning and continuous water supply, improves cleaning efficiency, ensures the rinsing effect of the staining tank and the automated operation of the equipment, and reduces the difficulty of manual operation.

[0014] This invention utilizes the coordinated operation of components such as the belt, suction blades, and air outlets in the drying mechanism. The rotating shaft drives pulley one to rotate, which in turn drives pulley two via the belt, which in turn drives the support shaft to rotate. This, in turn, drives the suction blades to rotate, generating air pressure. The airflow enters the ventilation opening, then the guide channel, and flows evenly through the air outlet, ensuring that the airflow covers the entire area. This rapid drying of the dyeing tank reduces waiting time. This design accelerates the drying process of the dyeing tank, significantly shortens the operation interval, improves work efficiency, and reduces unnecessary waiting time.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The purpose is to ensure that the staining tank 4 is automatically cleaned after the staining solution is used, so as to avoid staining residues from contaminating subsequent experiments.

[0021] The circumferential surface of the rotating shaft 53 is provided with a threaded groove 510. The rotating shaft 53 is threadedly connected to a threaded sleeve 511 through the threaded groove 510. One end of the water spray plate 59 is fixedly connected to the top of the threaded sleeve 511. The side of the threaded sleeve 511 is slidably connected to the inner wall of the power compartment 51. The purpose is to ensure that the water spray plate 59 can move during use, not limited to a local position.

[0022] A return spring 512 is fixedly connected inside the cleaning box 55. The end of the return spring 512 away from the inside of the cleaning box 55 is fixedly connected to the side of the extrusion plate 56. The purpose is to ensure that the extrusion plate 56 can automatically reset and reduce manual intervention.

[0023] The end of the force-bearing rod 57 away from the cleaning box 55 is located on the displacement trajectory of the push turntable 54. The initial position of the water spray plate 59 is located inside the power chamber 51. Its purpose is to ensure that the push turntable 54 can push one end of the force-bearing rod 57 during rotation.

[0024] The smear staining machine 1 is equipped with a drying mechanism 6. The drying mechanism 6 includes a pulley 61, which is fixedly connected to the end of the rotating shaft 53 away from the output shaft of the motor 52. A belt 62 is provided on the circumferential surface of the pulley 61. A ventilation port 63 is provided on the side of the smear staining machine 1. A support shaft 64 is rotatably connected through the ventilation port 63. A pulley 65 is fixedly connected to the end of the support shaft 64 that passes through the ventilation port 63. The pulley 61 is connected to the pulley 65 through the belt 62. A suction blade 66 is fixedly connected to the circumferential surface of the support shaft 64. A guide groove 67 is provided inside the ventilation port 63. An air blowing port 68 is provided inside the guide groove 67. The purpose of this is to dry the cleaned staining tank 4, accelerate the water loss rate, and reduce the waiting time.

[0025] The number of suction blades 66 is set to a certain number and is arranged in a circumferential array along the circumference of the support shaft 64. A dustproof plate 69 is provided inside the ventilation opening 63 to ensure sufficient airflow and prevent debris from entering the ventilation opening 63.

[0026] The number of air outlets 68 is set to a certain extent and is evenly distributed inside the guide groove 67. The purpose is to achieve uniform airflow distribution, improve airflow efficiency, and ensure that the airflow can effectively cover the entire area.

[0027] A specific application of this embodiment is as follows: When the smear stainer 1 finishes staining the malaria blood smear, the user removes the material and then starts the motor 52. The output shaft of the motor 52 drives the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 drives the rotating disk 54 to rotate. During the rotation of the rotating disk 54, its protrusion pushes one end of the force rod 57. The force rod 57 is forced to move the extrusion plate 56 inside the cleaning tank 55. At this time, the water inside the cleaning tank 55 is squeezed and enters the delivery hose 58, and then sprays out through the spray plate 59. At the same time, the rotating shaft 53 drives the threaded sleeve 511 to move linearly inside the power chamber 51 through the threaded groove 510. The movement of the threaded sleeve 511 drives the water spray plate 59 to move, thereby making the water spray plate 59 move while spraying water, rinsing the inside of the dyeing tank 4. When the protrusion of the push turntable 54 leaves one end of the force rod 57, the force rod 57 is no longer under force, so that the extrusion plate 56 is automatically reset by the elastic force of the return spring 512. By continuously pushing the turntable 54 automatically, the cleaning box 55 continuously supplies water to the delivery hose 58.

[0028] While the rotating shaft 53 rotates, it drives the pulley 61 to rotate. The rotation of pulley 61 drives the pulley 65 to rotate via the belt 62. The rotation of pulley 65 drives the support shaft 64 to rotate. The rotation of the support shaft 64 drives the suction blades 66 to rotate. The continuous rotation of multiple suction blades 66 generates wind pressure, which causes the airflow to enter the ventilation port 63 and then enter the guide channel 67. The airflow is evenly distributed through multiple air outlets 68 to ensure that the airflow can effectively cover the entire area and dry the cleaned dyeing tank 4, reducing waiting time.
