Description

Technical Field

[0001] The present invention relates to the technical field of medical detection, and in particular to a reagent card incubation device. Background Art

[0002] Incubation is a very important pre-processing step in medical experiments. Reagent cards are usually used for rapid detection and screening. The traditional incubation method is to use a heating plate to heat the reagent card and raise the temperature of the reagent card to a suitable temperature through heat conduction for incubation. However, as the market requirements for reagent card incubation continue to increase, the existing reagent card incubation device can no longer meet the actual needs of high efficiency and high standards. Therefore, we urgently need to improve the deficiencies in the application of the reagent card incubation device.

[0003] Currently, most mainstream reagent card incubation devices on the market still use intermittent incubation, whereby staff place the reagent card to be tested into the incubation device for heating and incubation, and then remove it for testing and screening after heating is complete. However, this incubation method not only suffers from high energy consumption and poor heating efficiency during the intermittent removal of the reagent card, but also lacks the ability to automatically detect the disease. This is particularly true during periods of widespread influenza and other disease outbreaks, severely impacting the incubation and detection efficiency of the reagent card, and consequently, the effectiveness of disease control.

[0004] To this end, we propose a reagent card incubation device to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned problem and to propose a reagent card incubation device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A reagent card incubation device includes a shell, the shell is connected to an incubation tray through the rotation of a motor, the incubation tray is connected to a heater at one end away from the motor, the incubation tray is movably connected to a reagent card through the heater, the reagent card first performs a first-stage incubation work in the shell area as the incubation tray rotates, a windshield is provided on the side of the incubation tray away from the heater, the windshield is movably connected to the incubation tray through a detection component, and the second-stage detection work of the reagent card is realized.

[0008] The incubation tray comprises a hollow shaft, a sealing plate and an outer ring, wherein the shell, the sealing plate and the outer ring form an annular working area;

[0009] An air cover is provided at one end of the housing close to the motor, and the air cover, the hollow shaft and the working area are connected via a heater;

[0010] Multiple groups of air pipes are symmetrically arranged on both sides of the shell, and adjacent air pipes are correspondingly arranged in the working area. One group of air pipes is connected to the air outlet end of the heater, and the other group of air pipes is connected to the air inlet end of the heater through the air cover and the hollow shaft.

[0011] Optionally, a feed port is provided at the top of the shell, a discharge port is provided at the bottom of the shell, a waste port is provided at one side of the shell, and the detection component is arranged on the side of the shell close to the discharge port.

[0012] Optionally, the outer ring is provided with a plurality of card slots, and the reagent cards and the card slots are arranged in coordination;

[0013] The card slot is provided with multiple groups of air holes on both sides close to the shell, and the air holes and the air pipes are provided correspondingly;

[0014] The end of the trachea close to the air hole adopts a trumpet-shaped opening design.

[0015] Optionally, the air pipe forms an arc-shaped incubation area in the working area, one end of the incubation area is connected to the feed port, the other end of the incubation area is connected to the discharge port, and the waste port is provided at the end of the shell away from the incubation area;

[0016] After the reagent card falls into the card slot of the incubation tray through the feed port, it rotates thereafter. The hot air generated by the heater passes through the air holes through the air pipe connected to the air outlet end to thermally incubate the reagent card in the card slot. At this time, the air pressure in the card slot near the back of the reagent card is lower than the air pressure at other air flow positions in the card slot, so that the reagent card is adsorbed on one side of the card slot under the action of negative pressure. The hot air after passing through the reagent card passes through the air holes and enters the air cover through another set of air pipes, and returns to the heater from the air inlet end through the hollow shaft to realize the warm air circulation for incubating the reagent card.

[0017] Optionally, the windshield adopts a rectangular structure, and a plurality of sliding rods are provided at one end of the windshield close to the air hole, and the sliding rods are arranged in cooperation with the air hole through springs.

[0018] Optionally, the detection component includes a laser emitter, a photoresistor and an electromagnet, the laser emitter is arranged on a side of the housing close to the discharge port, the photoresistor is arranged in the same vertical direction as the laser emitter, and the electromagnet is arranged on a side of the housing close to the windshield;

[0019] The laser emitter adopts a green light emitter, and the outlet is less than 1mm;

[0020] The card slot is provided with a strip-shaped detection port, and the light emitted by the laser emitter can be reflected to the position of the photoresistor after passing through the detection port to detect the detection area of ​​the reagent card.

[0021] Optionally, a magnetic block is provided at one end of the windshield away from the slide rod, and the electromagnet is controlled to be on and off by the photoresistor and is thus arranged in cooperation with the magnetic block;

[0022] The reagent card is rotated and incubated under the drive of the incubation disk. When a red single bar appears in the detection area of ​​the reagent card (indicating a negative test result), the light of the laser emitter is reflected at the specified position of the reagent card, and normal light is received by the photoresistor. At this time, the electromagnet is in a controlled power-off state; when a red double bar appears in the detection area of ​​the reagent card (indicating a positive test result), the light of the laser emitter is absorbed by the red color at the specified position of the detection area, so that the light received by the photoresistor is weakened (or even no light is received). At this time, the electromagnet is in a controlled power-on state, and the electromagnet is energized to generate a repulsive force on the magnetic block. The windshield fits the air holes of the card slot to block the wind, so that the reagent card slides out through the discharge port under the action of gravity.

[0023] The present invention has the following advantages:

[0024] The present invention provides a circulating incubation device, which can avoid the staff from using an intermittent heating incubation method during the detection process of batch reagent cards. While improving the detection efficiency of the reagent cards, it avoids the intermittent start and stop operation of the device, reduces the energy consumption of the device, and ensures the incubation and heating effect of the device. At the same time, after the device has been incubated for a certain period of time, it automatically performs detection and screening without manual screening, which greatly improves the incubation and detection efficiency of the reagent cards, especially during the period of large-scale spread of diseases such as influenza, and has a better treatment effect on disease control.

[0025] The present invention adopts a circulating turntable structure, so that the motor drives the incubation disk to rotate slowly, and the reagent card rotates accordingly. At this time, the hot air generated by the heater performs thermal incubation on the reagent card in the card slot. At the same time, since the air pressure of the card slot near the back side of the reagent card is lower than the air pressure at other air flow positions in the card slot, the reagent card is adsorbed on one side of the card slot under the action of negative pressure, and the hot air after passing through the reagent card returns to the heater to realize the warm air circulation of the reagent card incubation, thereby ensuring the stability of the incubation temperature and achieving the energy-saving effect of the device.

[0026] The present invention adopts the principle of emitting green light and being absorbed by a red detection line. When a red horizontal bar appears in the detection area of ​​the reagent card (indicating a negative test result), the light of the laser emitter is reflected at the specified position of the reagent card and the outer ring, and normal light reception is performed by the photoresistor. At this time, the electromagnet is in a power-off state under the control of the single-chip microcomputer. The reagent card continues to move through the discharge port under negative pressure adsorption until it moves out of the incubation area. The reagent card slides with the shell under the action of gravity and is discharged and collected through the waste port; when a red double bar appears in the detection area of ​​the reagent card (indicating a positive test result), the light of the laser emitter is absorbed by the red color at the specified position of the detection area, so that the light reception of the photoresistor is weakened (or even no light is received). At this time, the electromagnet is in a controlled power-on state. The power of the electromagnet generates a repulsive force on the magnetic block, so that the windshield fits the air holes of the card slot to block the wind. At this time, the reagent card slides out through the discharge port under the action of gravity, which is convenient for centralized inspection by staff.

[0027] The outstanding feature of the present invention is that it utilizes the warm air circulation incubation process to generate negative pressure on the reagent card, so that the reagent card can be limited and moved after incubation. When the green light emitter irradiates the rotating reagent card detection area, once the reagent card detects a positive result, the green light is absorbed and weakened by the red detection line, so that the light received by the photoresistor is weakened (or even no light is received), thereby controlling the electromagnet to energize. The electromagnet pushes the windshield to block the card slot air holes through the magnetic block, thereby realizing the screening of abnormal reagent cards. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-5 A reagent card 5 incubation device includes a shell 1. It should be noted that the interior of the shell 1 adopts a sealed design. A feed port 11 is provided on the top of the shell 1 to facilitate the staff to put in the reagent card 5 to be tested. A discharge port 12 is provided at the bottom of the shell 1 for removing the reagent card 5 that has abnormalities during the test. A waste port 13 is provided on one side of the shell 1 for discharging waste from the reagent card 5 in a normal state.

[0036] Reference Figure 3 The shell 1 is rotatably connected to the incubation tray 3 through the motor 2, and the end of the incubation tray 3 away from the motor 2 is connected to the heater 4. The incubation tray 3 is movably connected to the reagent card 5 through the heater 4. It should be noted that the incubation tray 3 includes a hollow shaft 31, a sealing plate 32 and an outer ring 33. The hollow shaft 31 is rotatably connected to the shell 1 through a bearing. The thickness of the sealing plate 32 is slightly smaller than the thickness of the inner cavity of the shell 1. The sealing plate 32 cooperates with the shell 1 and the outer ring 33 to form an annular working area, wherein the outer ring 33 is provided with multiple groups of card slots 34, and the reagent card 5 and the card slots 34 are cooperated to be used for the reagent card 5 to rotate with the incubation tray 3. The reagent card 5 includes a sample area (S) and a detection area (C\T). When the reagent card 5 detects positive during the incubation process, a red double bar will appear, and when the reagent card 5 detects negative during the incubation process, a red single bar will appear.

[0037] Furthermore, an air cover 8 is provided at one end of the shell 1 close to the motor 2, and the air cover 8, the hollow shaft 31 and the working area are connected through the heater 4; the specific connection method is: multiple groups of air pipes 9 are symmetrically provided on both sides of the shell 1, and adjacent air pipes 9 are correspondingly arranged in the working area, one group of air pipes 9 is connected to the air outlet end of the heater 4, and the other group of air pipes 9 is connected to the air inlet end of the heater 4 through the air cover 8 and the hollow shaft 31. Multiple groups of air guide holes are provided at the end of the hollow shaft 31 close to the air cover 8, so that the air flow can perform heat-sealing incubation work on the card slot 34 position when passing through the working area.

[0038] More specifically, see Figure 3 and Figure 4, multiple groups of air holes 35 are provided on both sides of the card slot 34 near the shell 1, and the air holes 35 and the air pipe 9 are correspondingly arranged. The end of the air pipe 9 near the air holes 35 adopts a trumpet-shaped opening design, so that the hot air can complete the full and uniform incubation of the reagent card 5 in the card slot 34 when passing through the incubation tray 3. Among them, the air pipe 9 forms an arc-shaped incubation area in the working area, one end of the incubation area is connected to the feed port 11, and the other end of the incubation area is connected to the discharge port 12. The waste port 13 is arranged at the end of the shell 1 away from the incubation area, so that the card slot 34 of the incubation tray 3 does not produce airflow adsorption when it is rotated to the waste port 13 position, which is convenient for detecting normal reagent cards 5 and performing normal waste discharge.

[0039] As the incubation tray 3 rotates, the reagent card 5 first performs the first stage of incubation in the shell 1 area. The specific incubation process is as follows: the reagent card 5 falls into the card slot 34 of the incubation tray 3 through the feed port 11 and then rotates. The hot air generated by the heater 4 passes through the air pipe 9 connected to the air outlet end and passes through the air hole 35 to perform thermal incubation on the reagent card 5 in the card slot 34. At this time, the air pressure in the card slot 34 near the back side of the reagent card 5 is lower than the air pressure at other air flow positions in the card slot 34, so that the reagent card 5 is adsorbed on one side of the card slot 34 under the action of negative pressure. The hot air after passing through the reagent card 5 passes through the air hole 35 and enters the air cover 8 through another set of air pipes 9, and returns to the heater 4 from the air inlet end through the hollow shaft 31 to realize the warm air circulation for incubating the reagent card 5.

[0040] Reference Figure 3 and Figure 4 A windshield 6 is provided on the side of the incubation tray 3 away from the heater 4. The windshield 6 is movably connected to the incubation tray 3 through the detection component 7 to realize the second stage detection work of the reagent card 5. It should be noted that the windshield 6 adopts a rectangular structure. A plurality of groups of sliding rods 61 are provided at one end of the windshield 6 close to the air hole 35. The sliding rods 61 are arranged in conjunction with the air hole 35 through the spring 62.

[0041] Reference Figure 3-5 The detection component 7 is arranged on the side of the shell 1 near the discharge port 12, wherein the detection component 7 includes a laser emitter 71, a photoresistor 72 and an electromagnet 73. The laser emitter 71 is arranged on the side of the shell 1 near the discharge port 12, the photoresistor 72 is arranged in the same vertical direction as the laser emitter 71, and the electromagnet 73 is arranged on the side of the shell 1 near the windshield 6. The card slot 34 is provided with a strip-shaped detection port 36. The light emitted by the laser emitter 71 can be reflected to the position of the photoresistor 72 after passing through the detection port 36 to detect the detection area (T line position) of the reagent card 5. The laser emitter 71 adopts a green light emitter, and the outlet is less than 1 mm, so that the light emitted by the laser emitter 71 is thin enough to avoid the error caused by reflection of the photoresistor 72.

[0042] A magnetic block 63 is provided at one end of the windshield 6 away from the slide rod 61. The electromagnet 73 controls the power on and off under the action of the photoresistor 72 and is then arranged in cooperation with the magnetic block 63. It is worth mentioning that the reagent card 5 is rotated and incubated under the drive of the incubation disk 3. When a red single bar appears in the detection area of ​​the reagent card 5 (displaying a negative test result), the light of the laser emitter 71 is reflected at the specified position of the reagent card 5 and normal light reception is performed by the photoresistor 72. At this time, the electromagnet 73 is in a controlled power-off state; when a red double bar appears in the detection area of ​​the reagent card 5 (displaying a positive test result), the light of the laser emitter 71 is absorbed by the red color at the specified position of the detection area, so that the light received by the photoresistor 72 is weakened (or even no light is received). At this time, the electromagnet 73 is in a controlled power-on state. The electromagnet 73 is energized to produce a repulsive force on the magnetic block 63, and the windshield 6 fits the air hole 35 of the card slot 34 to block the wind, so that the reagent card 5 slides out through the discharge port 12 under the action of gravity.

[0043] Furthermore, the outer ring 33 and the reagent card 5 are in a white reflective state under normal conditions, so that the light emitted by the laser emitter 71 during the rotation of the incubation plate 3 can be received by the photoresistor 72, wherein the photoresistor 72 controls the power on and off of the electromagnet 73 through the single-chip microcomputer, so that when the photoresistor 72 receives light, the electromagnet 73 is in a power-off state, and when the photoresistor 72 does not receive light, the electromagnet 73 is in a power-on state. After being energized, the electromagnet 73 is close to one pole of the magnetic block 63 and is in the same polarity state as the magnetic block 63, thereby generating a repulsive force between the electromagnet 73 and the magnetic block 63, thereby pushing the wind shield 6 to the corresponding position of the card slot 34 to perform wind shielding work.

[0044] The operating environment temperature of the present invention is 5° C. to 30° C.; the relative humidity is 5% to 80%, without condensation; the atmospheric pressure is 75 kPa to 106 kPa; and the power supply voltage is ac220V±22V, 50Hz±1Hz.

[0045] The operating principle of the present invention is now described as follows:

[0046] When the device is in use, the motor 2 drives the incubation tray 3 to rotate slowly, and the staff puts the reagent card 5 to be tested into the card slot 34 of the incubation tray 3 through the feed port 11, and the reagent card 5 rotates accordingly. At this time, the hot air generated by the heater 4 passes through the air pipe 9 connected to the air outlet end and the air hole 35 to perform thermal incubation on the reagent card 5 in the card slot 34 (the initial incubation temperature of the present invention is set to 25°C, and the time is usually 15 minutes). Since the air pressure in the card slot 34 near the back side of the reagent card 5 is lower than the air pressure at other air flow positions in the card slot 34, the reagent card 5 is adsorbed on one side of the card slot 34 under the action of negative pressure, and the hot air after passing through the reagent card 5 passes through the air hole 35 and enters the air cover 8 through another set of air pipes 9, and returns to the heater 4 from the air inlet end through the hollow shaft 31 to realize the warm air circulation for incubating the reagent card 5.

[0047] During the incubation process, the reagent card 5 rotates and is driven by the incubation disk 3. When a red horizontal bar appears in the detection area of ​​the reagent card 5 (indicating a negative test result), the light of the laser emitter 71 is reflected at the specified position of the reagent card 5 and the outer ring 33, and normal light reception is performed by the photoresistor 72. At this time, the electromagnet 73 is in a power-off state under the control of the single-chip microcomputer, and the reagent card 5 continues to move through the discharge port 12 under negative pressure adsorption until it moves out of the incubation area. The reagent card 5 slides with the housing 1 under the action of gravity and is discharged through the waste port 13. Discharge and collection; when a red double bar appears in the detection area of ​​the reagent card 5 (indicating a positive test result), the light from the laser emitter 71 is absorbed by the red color at the specified position of the detection area, causing the photoresistor 72 to receive less light (or even receive no light). At this time, the electromagnet 73 is in a controlled power-on state, and the electromagnet 73 is energized to produce a repulsive force on the magnetic block 63, causing the windshield 6 to fit the air hole 35 of the card slot 34 to block the wind. At this time, the reagent card 5 slides out through the discharge port 12 under the action of gravity, which is convenient for centralized inspection by the staff.

[0048] The present invention should avoid rain and snow splashing and mechanical collision during transportation, and must not be mixed or transported with corrosive substances. The equipment storage warehouse should be dry, with an ambient temperature of 0℃~+40℃ and a relative humidity of no more than 90%.
