Description

Technical Field

[0001] This invention belongs to the technical field of reagent storage boxes, and more specifically, relates to a reagent storage device for medical testing. Background Technology

[0002] The storage of reagent tubes used in medical testing needs to take into account the sample storage environment. For example, in virus testing, the storage box needs to be sterilized to prevent bacterial contamination of the sample from inside the storage box. Existing sterilization methods have the following technical problems: Disinfecting the storage box with ultraviolet light is not effective because the internal structure of the storage box is small and the ultraviolet light cannot kill all the bacteria. Furthermore, the reagent tubes themselves may carry bacteria, making the process even more difficult when the reagent tubes are placed inside the storage box, resulting in poor disinfection and operation.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its defects to provide a reagent storage device for medical testing. Summary of the Invention

[0007] In a further technical solution, the locking ring includes a connecting ring, elastic claws, and the wind deflector. The locking ring is sleeved on the inner cylinder. The upper side of the locking ring has a plurality of elastic claws arranged in annular array. The inner cylinder is recessed on the upper outer wall of the vent to form an annular groove. The elastic claws are engaged in the annular groove. The lower side of the connecting ring is fixedly connected to the wind deflector, and the wind deflector is embedded in the vent.

[0008] In a further technical solution, the inner wall surface of the vent is a slope, the side wall of the wind deflector is an inclined surface that cooperates with the slope, and a ventilation gap is formed between the wind deflector and the vent.

[0009] In a further technical solution, the main body shell has an operating compartment, and the switching mechanism includes multiple rotating rods arranged horizontally in the operating compartment. The rotating rods can rotate in the operating compartment, and a cam is fixedly installed on the rotating rod. The cam can abut against the movable tail when it rotates.

[0010] In a further technical solution, the cam has a disk at its center, and the disk has a movable groove that extends radially along the disk. A movable shaft is slidably disposed within the movable groove, and an operating rod is connected to the movable shaft. The operating rod extends outward and passes through the wall of the main body shell, and a button is disposed at the outer end of the operating rod on the main body shell.

[0011] In a further technical solution, a cooling plate is provided on the inner wall of the high-pressure chamber, the air outlet of the high-pressure tank is aligned with the cooling plate, and a filter plate is provided in the low-pressure chamber, the filter plate separating the side groove and the low-pressure chamber.

The battery pack is connected to the cooling chip, the display module and the control module through cables.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a reagent storage device for medical testing. By incorporating a locking component and a switching mechanism, the locking component is optimized and improved. It includes a movable tail, a locking ring, a vent, and a baffle plate. Normally, the locking component locks the reagent tube. When reagent tube storage is required, pressing the corresponding button causes the movable tail to push the fixed claw away from the inner wedge block. The baffle plate, being elastic, naturally releases its blockage of the vent, increasing the distance between the two baffle plates and facilitating reagent tube insertion. The reagent tube is then inserted into the locking component from top to bottom. Releasing the button causes the movable tail to move away from the inner cylinder under the push of the return spring, causing the fixed claw to squeeze the two baffle plates closer together. The two baffle plates clamp the reagent tube, thus locking it. The operation logic is simple and convenient. Furthermore, the locking and unlocking structure does not contain any electronic components, requires no power, and is simple and reliable.

[0016] The switching mechanism of this invention pushes the movable tail upward, which in turn moves the outer cylinder and the fixed claw upward and disengages from the inner wedge block. When the inner wedge block is no longer squeezed by the outer wedge block, the baffle plate, under its own elasticity, disengages from the vent, forming a ventilation gap between the vent and the baffle plate. The high-pressure inert gas in the high-pressure tank enters the high-pressure chamber, creating a high-pressure environment. The gas in the high-pressure chamber enters the inner cavity of the inner cylinder through the ventilation gap and cools the reagent tube inside the inner cylinder. The airflow flows from top to bottom through the reagent tube and flows into the low-pressure chamber through the exhaust hole. The gas finally flows into the side groove. This device, by setting a sterilization device and using a plasma generator, makes the gas contain sterilizing plasma. Every time the airflow flows through the reagent tube wall, it sterilizes the reagent tube. Each time the lock is opened, the airflow flows evenly from beginning to end through the reagent tube, resulting in better sterilization and cooling effects. Furthermore, each time the lock is opened, the reagent tube automatically pops out for easy removal by the operator. Attached Figure Description

[0024] See attached document Figure 1 To be continued Figure 12This invention provides a reagent storage device for medical testing, comprising a main shell 10, with storage boxes 19 inclined upwards on the left and right sides of the main shell 10, respectively. A first partition 24, a second partition 25, and a third partition 27 are spaced apart inside the storage box 19. A sealed high-pressure chamber 26 is formed between the first partition 24 and the second partition 25, and a sealed low-pressure chamber 28 is formed between the second partition 25 and the third partition 27. A threaded hole 33 is provided on the first partition 24, a middle hole 34 is provided on the second partition 25, and a bottom hole 35 is provided on the third partition 27. The threaded hole 33, the middle hole 34, and the bottom hole 35 are concentrically arranged. A locking component 18 is threadedly installed in the threaded hole 33, with its tail extending downwards into the middle hole 34 and the bottom hole 35. The locking component 18 includes an inner cylinder 39, an outer cylinder 41, and a locking ring 40. The inner cylinder 39 is fitted with a slidable outer cylinder 41. A ventilation opening 51 is provided on the side wall of the inner cylinder 39. The locking ring 40 is fitted onto the inner cylinder 39 and has a wind deflector 48 that blocks the ventilation opening 51. The outer wall of the wind deflector 48 has an inner wedge-shaped block 49. The outer cylinder 41 has a fixing claw 46, which abuts against the inner wedge-shaped block 49. The rear of the inner cylinder 39 is provided with a movable tail 43 that can move along the axis of the inner cylinder 39. The movable tail 43 is fixedly connected to the outer cylinder 41. The movable tail 43 and the inner cylinder 39 are connected... A reset spring 45 is provided between the inner cylinder 39 and the lower side of the inner cylinder 39 is provided with an exhaust hole 55, which is connected to the low-pressure chamber 28. The ventilation port 51 is connected to the high-pressure chamber 26. A high-pressure tank 13 is provided on the outer wall of the main body shell 10. The high-pressure tank 13 is connected to the high-pressure chamber 26 through a pipe. A side groove 21 is also provided on the side wall of the main body shell 10. The side groove 21 is connected to the low-pressure chamber 28. A switching mechanism for driving the movable tail 43 to move is also provided inside the main body shell 10.

[0025] In this embodiment, the switching mechanism pushes the movable tail 43 upward, and the movable tail 43 drives the outer cylinder 41 and the fixed claw 46 upward and disengages from the inner wedge block 49. In this embodiment, the inner wall surface of the fixed claw 46 is provided with an outer wedge block 50. The outer wedge block 50 and the inner wedge block 49 abut against each other. When the inner wedge block 49 is not squeezed by the outer wedge block 50, the wind deflector 48 disengages from the vent 51 under its own elasticity. The wind deflector 48 disengages from the wall of the reagent tube, thereby unlocking the reagent tube. A ventilation gap is formed between the vent 51 and the wind deflector 48. The high-pressure inert gas in the high-pressure tank 13 enters the high-pressure chamber 26, and the high-pressure chamber 26 forms a high-pressure environment. The gas in the high-pressure chamber 26 enters the inner cavity of the inner cylinder 39 through the ventilation gap and cools the reagent tube in the inner cylinder 39. The airflow flows from top to bottom through the reagent tube and flows into the low-pressure chamber 28 through the exhaust hole 55. The gas finally flows into the side groove 21.

[0026] In practice, the bottom surface of the active tail 43 is an arc-shaped surface, which smoothly matches the cam 38.

[0027] In other embodiments of this application, the arc-shaped surface of the movable tail 43 has a protruding dividing strip, and the cam 38 can contact the dividing strip when rotated to a certain angle.

[0028] A clamp 23 is fixedly installed on the side wall of the main shell 10, and the clamp 23 clamps the high pressure tank 13.

[0030] In this embodiment, the piston body 42 abuts against the bottom of the reagent tube. When the switching mechanism pushes the movable tail 43 to move upward, the inner cylinder 39 remains fixed. The movable tail 43 squeezes the reset spring 45, and the sliding shaft 56 slides in the sliding groove 54. At this time, the piston body 42 remains fixed until the movable tail 43 drives the outer cylinder 41 to move upward. The outer cylinder 41 drives the wind deflector 48 to lock the reagent tube. At this time, the reagent tube is not restricted in the vertical direction. Under the push of the buffer spring 44, the reagent tube automatically pops out, making it convenient for the operator to take it out.

[0031] Preferably, the locking ring 40 includes a connecting ring, elastic claws 47, and the wind deflector 48. The locking ring 40 is sleeved on the inner cylinder 39. The upper side of the locking ring 40 has a plurality of elastic claws 47 arranged in a ring. The inner cylinder 39 is recessed in the upper outer wall of the vent 51 to form an annular groove 52.

[0037] Preferably, the cam 38 has a disk 57 at its center, and the disk 57 has a movable groove 58 that extends radially along the disk 57. A movable shaft 59 is slidably disposed within the movable groove 58, and an operating rod 31 is connected to the movable shaft 59. The operating rod 31 extends outward and passes through the wall of the main body shell 10, and a button 15 is disposed at the outer end of the operating rod 31 on the main body shell 10.

[0038] Preferably, the inner wall of the high-pressure chamber 26 is provided with cooling fins, the air outlet of the high-pressure tank 13 is aligned with the cooling fins, and a filter plate 22 is provided in the low-pressure chamber 28, the filter plate 22 separating the side groove 21 and the low-pressure chamber 28.

[0039] In this embodiment, when the exhaust gas passes through the filter plate 22, the filter plate 22 filters and disinfects the exhaust gas.

[0040] The filter plate 22 is detachably connected in the low-pressure chamber 28 via a snap-fit ​​connection for easy replacement.

[0041] In other embodiments of this application, an ultraviolet disinfection device is also provided in the low-pressure chamber 28, which irradiates the filter plate 22 to disinfect it.

[0042] In other embodiments of this application, a plasma generator may be installed on the inner wall of the high-pressure chamber 26. Gas flows through the ion generator, carrying sterilizable plasma from top to bottom through the reagent tube, thereby achieving the sterilization effect on the outer wall of the reagent tube.

[0043] Preferably, the upper opening of the storage box 19 is recessed to form a cover groove 37, the inner wall of the cover groove 37 has a slide rail, a sliding cover 12 is provided at the opening of the cover groove 37, the sliding cover 12 cooperates with the slide rail to open and close the opening of the cover groove 37, and a sealing gasket 20 is provided on the lower side of the sliding cover 12 to block the opening of the locking component 18.

[0044] Preferably, side covers 11 are provided on both sides of the main body shell 10. The side covers 11 can be detachably sealed to the side groove 21. An exhaust pipe 17 is also provided on the side cover 11. One end of the exhaust pipe 17 passes through the side cover 11 and communicates with the side groove 21. A valve is provided at the opening of the other end of the exhaust pipe 17.

[0045] Preferably, the bottom of the main body shell 10 is recessed to form a battery slot 60, and a battery pack is also provided at the bottom of the main body shell 10. The battery pack is installed in the battery slot 60. A temperature sensor is also provided in the high-pressure chamber 26. A display module and a control module are also provided on the outer wall of the main body shell 10. The battery pack is connected to the cooling chip, the display module and the control module through a cable.

[0046] In a specific implementation, a protrusion 61 is fixedly installed on the operating lever 31, and multiple electric telescopic rods 62 are installed on the inner wall of the operating chamber 29, with the shafts of the electric telescopic rods 62 extending towards the protrusion 61. The control module is also electrically connected to the electric telescopic rods 61. The control module controls the extension and retraction of the electric telescopic rods 61 to adjust the rotation angle of the cam 38.

[0047] In this embodiment, a temperature sensor detects the temperature inside the high-pressure chamber. When the temperature is higher than the set value, the control module controls the electric telescopic rod to extend a certain length so that the vent 51 opens. The low-temperature gas inside the high-pressure chamber passes through the vent 51 and flows through the outer wall of the reagent tube, and finally flows into the low-pressure chamber to achieve a targeted cooling effect.

[0048] Specific usage of this invention: The device is normally locked in the reagent tube state. When it is necessary to store the reagent tube, slide the sliding cover 12 to open the cover slot 37, press the button 15 in the corresponding position, and the button 15 pushes the disc 57 and cam 38 to rotate through the operating rod 31 and the movable shaft 59, so that the cam 38 abuts against the movable tail 43. The movable tail 43 pushes the fixed claw 46 to disengage from the inner wedge block 49. The wind baffle 48 itself is elastic and naturally disengages from blocking the vent 51. The distance between the two wind baffles 48 increases, providing conditions for the insertion of the reagent tube. Insert the reagent tube into the locking assembly 18 from top to bottom, release the press of the button 15, and under the push of the return spring 45, the movable tail 43 moves away from the inner cylinder 39 and drives the fixed claw 46 to squeeze the two wind baffles 48 closer to each other. The two wind baffles 48 clamp the reagent tube, realizing the function of locking the reagent tube.

[0049] The switching mechanism pushes the movable tail 43 upward, which in turn drives the outer cylinder 41 and the fixed claw 46 upward and disengages from the inner wedge block 49. When the inner wedge block 49 is no longer squeezed by the outer wedge block 50, the wind deflector 48 disengages from the vent 51 under its own elasticity, forming a ventilation gap between the vent 51 and the wind deflector 48. The high-pressure inert gas in the high-pressure tank 13 enters the high-pressure chamber 26, forming a high-pressure environment. The gas in the high-pressure chamber 26 enters the inner cavity of the inner cylinder 39 through the ventilation gap and cools the reagent tubes in the inner cylinder 39. The airflow flows from top to bottom through the reagent tubes and into the low-pressure chamber 28 through the exhaust hole 55. Finally, the gas flows into the side groove 21.

[0050] Each unlocking operation causes cooling gas to flow through the outer wall of the reagent tube. The process has two stages. When the cam 38 rotates to the first angle, the movable tail 43 moves upward and creates a gap between the vent 51 and the baffle 48 to achieve cooling. At this time, the baffle 48 clamps the reagent tube with the elastic anti-slip strip, and the piston body 42 cannot move upward. When the cam 38 continues to rotate to the second angle, the elastic anti-slip strip of the baffle 48 disengages from the reagent tube, and the buffer spring 44 pushes the piston body 42 upward and pushes the reagent tube upward.

[0051] This device has two operating states, which can be activated as needed. For example, when the temperature sensor detects that the temperature inside the high-pressure chamber 26 has risen and exceeded the set value, the control module controls the electric telescopic rod 62 to extend. The electric telescopic rod 62 pushes the protrusion 61, which in turn moves the operating rod 31 and rotates the cam 38 to the first angle to achieve cooling and maintain the locked state. As another example, when it is necessary to unlock all reagent tubes, the control module controls all the electric telescopic rods 62 to extend, causing the cam 38 to rotate to the second angle, and all reagent tubes pop out simultaneously for quick extraction by the operator.

[0052] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
