Description

Technical Field

[0001] The present invention relates to the technical field of storage devices, and in particular to a blood sample storage device for hematology. Background Art

[0002] Hematology is a branch of internal medicine that primarily treats diseases of the hematopoietic system, also known as blood disorders. In some hospitals, chemotherapy for cancer is often linked to hematological diseases, forming a related specialty. The hematology department is comprised of two specialties: hematology and oncology, collectively known as the oncohematology department.

[0003] Hematology is an independent branch of medicine that focuses on the study of blood and hematopoietic tissue. The blood system is primarily composed of hematopoietic tissue and blood, and hematologic diseases refer to disorders that primarily (such as leukemia) or primarily affect (such as iron deficiency anemia) the blood, hematopoietic tissue, and organs. The diagnosis of hematologic diseases primarily relies on laboratory testing of blood samples.

[0004] Blood sample storage devices in the prior art are generally simple storage boxes or storage racks. The collected samples are generally stored at room temperature, which is prone to coagulation over time and is inconvenient for testing and analysis. To address this problem, a low-temperature insulation box is conventionally used for storage. The insulation box has a simple structure, and the box lid needs to be opened frequently during the process of taking and placing samples, resulting in a large amount of air convection inside and outside, and poor insulation effect. In addition, some smaller hospitals do not have blood testing equipment, and blood samples collected that day need to be sent to larger hospitals for testing. However, the storage box does not have the function of fixing the blood sampling tubes. During transportation, the sampling tubes may collide with the inner wall of the box due to bumps and be damaged.

[0005] Therefore, it is necessary to design a blood sample storage device that is convenient to transport and can reduce a large amount of air convection inside and outside the storage device box when taking the blood sample, thereby improving the heat preservation effect. Summary of the Invention

[0006] The present invention aims to provide a blood sample storage device for hematology to solve the technical problems in the prior art of convenient transportation of blood samples, preventing large-scale air convection inside and outside the device when taking blood samples, and improving the thermal insulation effect.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The lid is hinged to the box body through a pin, and the lid is hinged to the box body through a pin. The lid is provided with an opening near the top of the front face, and a sealing cover is provided at the opening of the lid. The inner wall of the box body is provided with a limit assembly and a support plate, and the support plate is rotatably connected to the inner wall of the box body through the limit assembly. The support plate is a regular polygon adapted to the box body, and each side of the support plate is provided with a placement rack for placing blood samples. The top view of the placement rack is trapezoidal, and the placement rack consists of four vertical plates and one horizontal plate, the vertical plates of the placement rack are provided with a plurality of vents, and the horizontal plates of the placement rack are provided with a plurality of placement holes. The bottom of the inner wall of the placement rack is slidably connected to a base assembly, and the bottom of the base assembly is provided with a spring mechanism.

[0009] A vertical rod is provided on the top of the support plate, a knob is provided on the top of the box cover, and the knob is provided with a transmission assembly that passes through the box cover. The knob is fixedly connected to the vertical rod through the transmission assembly.

[0010] The principle of the technical solution is as follows: when the storage box is closed, the spring in the spring mechanism is in a compressed state, so that the blood sample tubes on the storage rack are just stored in the box. When it is necessary to intermittently take out the blood sample tubes from the storage box, the medical staff first rotates the knob, and the transmission assembly can fix the knob to the vertical rod, thereby achieving the purpose of rotating the support plate. The limit assembly can accurately position the target storage rack directly under the window, open the sealing cover, and press the blood sample tube to achieve the purpose of pressing the spring mechanism. At this time, the elastic force of the middle spring of the spring mechanism pushes the base assembly upward along the storage rack, driving the blood sample tubes in the storage rack upward, thereby facilitating the medical staff to take the blood sample tubes in the box, and can reduce the large amount of air convection inside and outside the box, thereby improving the thermal insulation effect. At the same time, when intermittently placing blood sample tubes, it is only necessary to rotate the idle storage rack to the bottom of the opening. When the blood sample tubes need to be transported, the fixed connection between the knob and the vertical plate is released by rotating the knob. Under the action of the limit assembly, it is difficult for the box to rotate, and the stored blood is not easily centrifuged, which affects the test results.

[0011] Furthermore, the spring mechanism includes a fixed plate, a groove is provided on one side of the fixed plate, a slider is provided in the groove, a slide rail is provided on the side of the slider away from the groove, the slide rail is heart-shaped, a connecting rod is slidably connected in the slide rail, the connecting rod is rotatably connected to the bottom of the fixed plate through a pin shaft, a spring is provided at the bottom of the slider fixedly connected to the bottom wall of the groove, and a slide rod is provided at the top of the slider that passes through the fixed plate and is fixedly connected to the bottom support assembly.

[0012] The spring mechanism is provided to facilitate medical personnel to take the blood sample tube. When in use, the blood sample tube is pressed to drive the bottom support assembly to move downward, causing the spring 1 to be compressed and then rebound, driving the connecting rod 1 to slide along the slide rail to the higher point of the slide rail. Under the elastic force of the spring 1, the bottom support assembly is pushed upward, thereby lifting the compressed blood sample tube out of the opening, making it easier to take the blood sample tube.

[0013] Furthermore, guide rods are respectively provided at both ends of the inner part of the spring 1, one of the guide rods is fixedly connected to the slider 1, and the other guide rod is fixedly connected to the fixed plate. The top of the base support assembly is provided with a vertical rod that passes through and extends to the top of the horizontal plate of the placement rack, and the top of the support plate is provided with several springs 2 that are fixedly connected to the base support assembly.

[0014] The setting of the guide rod can prevent the spring from twisting and affecting the use of the spring mechanism, while the setting of the vertical rod makes it easier for medical staff to perform pressing operations. The setting of spring two can make the bottom support assembly slide more smoothly and less likely to get stuck.

[0015] Furthermore, an accommodating cavity is provided at the top of the vertical rod, and the transmission assembly is located in the accommodating cavity. The transmission assembly includes a limit plate with a sliding groove on one side, and the limit plate is fixed to the bottom of the box cover. The bottom of the knob is provided with a rotating rod that penetrates the limit plate and extends to the sliding groove of the limit plate. The two ends of the rotating rod located in the sliding groove of the limit plate are symmetrically threaded with sliders 2, and the sliders 2 slide in opposite directions along the rotating rod through positive and negative double threads. The two side surfaces of the sliders 2 are symmetrically hinged with connecting rods 2, and the two connecting rods 2 located on the same side are movably connected by pins.

[0016] By setting up the transmission assembly, the knob and the vertical plate can be fixed to play the role of transmitting force; when in use, the knob is rotated clockwise to drive the rotating rod to rotate, and the rotating rotating rod can drive the two sliders to move toward each other, thereby driving the two connecting rods on the same side to move toward each other, so that the two connecting rods are against the inner wall of the accommodating cavity, thereby fixing the knob and the vertical plate, thereby driving the support plate to rotate.

[0017] Furthermore, the accommodating cavity is slidably connected to a slider four, and the slider four is fixedly connected to the accommodating cavity by a spring.

[0018] By setting the slider 4, when the box cover falls, the limit plate can play a buffering effect under the action of the spring, so that the box cover will not directly hit the box body.

[0019] Furthermore, the bottom support assembly includes a slide plate, which is slidably connected to the inner wall of the placement rack. The slide plate is provided with a plurality of placement grooves corresponding to the placement holes. The inner wall of the placement groove is slidably connected to a bottom support block, and the bottom of the bottom support block is provided with a spring three fixedly connected to the placement groove.

[0020] The arrangement of the bottom support assembly can buffer the elastic force of the spring mechanism. During use, when the bottom support assembly is subjected to the elastic force of spring one, the slide plate moves upward, squeezing spring three. The restorative elastic force of the squeezed spring three continues to push the bottom support block upward, preventing the blood sample tube from being squeezed too quickly, thereby alleviating the impact force on the blood sample tube.

[0021] Furthermore, an elastic buffer layer and a blood sample tube are sequentially provided on the inner wall of the placement hole, and the contact surface between the elastic buffer layer and the blood sample tube is a smooth surface.

[0022] The elastic buffer layer facilitates the fixation of the blood sample tube, and the smooth surface facilitates the placement and removal of the blood sample tube.

[0023] Furthermore, the limiting assembly includes a slider three, which is fixed at the outer corner of the support plate. A hollow column is provided below the slider three, and a rod is inserted into the hollow column. A spring four is provided between the rod and the hollow column. A ball is provided at the bottom of the rod, and a slide groove for the ball to slide is provided on the inner wall of the box, and the slide groove has several positioning grooves distributed at equal intervals.

[0024] By setting the limit assembly, the support plate is not easily rotated due to external impact during transportation, and the placement rack can be positioned quickly and accurately; when in use, when the ball rotates to the positioning groove, the placement rack is just below the opening.

[0025] Furthermore, a heat insulation cover is provided on the inner bottom wall of the box body directly below the vertical rod, an electric fan is provided inside the heat insulation cover, the fan blades of the electric fan are located above the heat insulation cover, a plurality of ventilation holes are provided on the support plate located above the electric fan, and a removable heat dissipation plate is provided on the box body below the heat insulation cover.

[0026] By setting up the electric fan and the heat insulation cover, the cold air in the box can be evenly distributed.

[0027] Furthermore, a transparent window is provided on the top of the box cover, the sealing cover is made of a transparent material, a temperature sensor is provided on the front inner wall of the box body, a temperature display and a control panel are provided on the front of the box body, a refrigerator and a battery are also provided on the inner bottom wall of the box body, and a carrying handle is provided on the top of the box cover.

[0028] The transparent window makes it easier for medical staff to observe the situation inside the box.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. The present invention, through the ingenious design of the spring mechanism, the limit assembly, and the transmission assembly, can accurately place the target placement rack directly below the opening. Pressing the spring mechanism can cause the blood sample tube to pop out of the opening, making it easier for medical staff to pick it up, thereby preventing large-scale air convection inside and outside the box and improving the thermal insulation effect. At the same time, when transporting the blood sample tube, the fixed connection between the knob and the vertical rod can be released by the transmission assembly. Under the action of the limit assembly, the support plate can be prevented from rotating inside the box when the box is subjected to impact force, which may affect the test results of the blood sample.

[0031] 2. The base assembly of the present invention can buffer the impact of the spring mechanism on the blood sample, thereby avoiding affecting the test results of the blood sample. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the box cover 2 is provided with a handle 49 and a transparent window 32. The transparent window 32 facilitates medical staff to observe the situation inside the box body 1. An opening 3 is provided at the top of the box cover 2 near the front, and a sealing cover 4 is provided at the opening 3 of the box cover 2. The sealing cover 4 is made of a transparent material and is hinged to the box cover 3 through a pin.

[0044] The inner wall of the box body 1 is provided with a limit assembly and a support plate 5, which is rotatably connected to the inner wall of the box body 1 through the limit assembly. The support plate 5 is a regular hexagon, and each side of the support plate 5 is provided with a placement rack 6 for placing blood samples. The top view of the placement rack 6 is an isosceles trapezoid, and the placement rack 6 consists of four vertical plates and a horizontal plate. The vertical plates of the placement rack 6 are provided with a number of vents 7 (partially not shown), and the horizontal plate of the placement rack 6 is provided with a number of placement holes 8. The bottom of the inner wall of the placement rack 6 is slidably connected with a bottom support assembly, and the bottom of the bottom support assembly is provided with a spring mechanism; a vertical rod 9 is provided at the middle part of the top of the support plate 5, and a knob 10 is provided on the top of the box cover 2. The knob 10 is provided with a transmission assembly that passes through the box cover 2, and the knob 10 is fixedly connected to the vertical rod 9 through the transmission assembly.

[0045] The spring mechanism includes a fixed plate 11, with a groove 12 formed on one side of the fixed plate 11. A slider 13 is positioned within the groove 12. A heart-shaped slide rail 14 is positioned on the side of the slider 13 facing away from the groove 12. A connecting rod 15 is slidably connected within the slide rail 14. Connecting rod 15 is movably connected to the bottom of the fixed plate 11 via a pin. A spring 16 is positioned at the bottom of the slider 13, fixedly connected to the inner bottom wall of the groove 12. A slide rod 17 is positioned at the top of the slider 13, extending through the fixed plate 11 and fixedly connected to the base assembly. The spring mechanism facilitates access to a blood sample tube 31 by medical personnel. During use, pressing the blood sample tube 31 causes the base assembly to move downward, causing the spring 16 to compress and then rebound, driving the connecting rod 15 to slide along the slide rail 14 to its highest point. The elastic force of the spring 16 pushes the base assembly upward, thereby lifting the compressed blood sample tube 31 out of the opening 3, making it easier for medical personnel to access the blood sample tube 31.

[0046] Guide rods 18 are respectively provided at both ends of the inner part of the spring 16, one guide rod 18 is fixedly connected to the slider 13, and the other guide rod 18 is fixedly connected to the fixed plate 11, which can prevent the spring from twisting, thereby affecting the use of the spring mechanism; the top of the bottom support assembly is provided with a vertical rod 19 that passes through and extends to the top of the horizontal plate of the placement rack 6, and the vertical rod 19 is slidably connected to the placement rack 6, which is convenient for medical staff to perform pressing operations; the top of the support plate 5 is provided with several springs 20 fixedly connected to the bottom support assembly, which can make the bottom support assembly slide more smoothly and less likely to get stuck.

[0047] A accommodating chamber 21 is provided at the top of the vertical rod 9, and a slider 4 50 is slidably connected to the accommodating chamber 21. The slider 4 50 is fixedly connected to the accommodating chamber 21 by a spring. The transmission assembly is located in the accommodating chamber 21 and is against the slider 4 50. Through the setting of the slider 4 50, when the box cover 2 falls, the limit plate 22 can play a buffering effect under the action of the spring, so that the box cover 2 will not directly hit the box body 1.

[0048] The transmission assembly includes a limit plate 22 with a sliding groove on one side. The limit plate 22 is fixed to the bottom of the box cover 2. The bottom of the knob 10 is provided with a rotating rod 23 that penetrates the limit plate 22 and extends into the groove of the limit plate 22. The two ends of the rotating rod 23 located in the sliding groove of the limit plate 22 are symmetrically threaded with two sliders 24. The two sliders 24 slide in opposite directions along the rotating rod 23 through positive and negative double threads. The two sliders 24 are slidingly connected to the inner wall of the sliding groove of the limit plate 22. The front sides of the slider 24 are symmetrically hinged with connecting rods 25. The two connecting rods 25 on the same side are movably connected by a pin. When the box cover 2 is closed, the limit plate 22 is against the slider four 50, and the spring between the slider four 50 and the accommodating cavity 21 is in a compressed state. By setting the transmission assembly, the knob 10 can be fixed to the vertical rod 9, which plays the role of transmitting force; when in use, the knob 10 is rotated clockwise to drive the rotating rod 23 to rotate, and the rotating rotating rod 23 can drive the two sliders 24 to move toward each other, thereby driving the connecting rod 25 on the same side to move toward each other, so that the connecting rod 25 is against the inner wall of the accommodating cavity 21, thereby fixing the knob 10 to the vertical rod 9, thereby driving the support plate 5 to rotate.

[0049] The bottom support assembly includes a slide 26, which is slidably connected to the inner wall of the placement rack 6. Slide 26 is provided with a plurality of placement slots 27 corresponding to the placement holes 8. A bottom support block 28 is slidably connected to the inner wall of the placement slots 27. A spring 3 29 is provided at the bottom of the bottom support block 28, which is fixedly connected to the placement slots 27. The arrangement of the bottom support assembly serves to buffer the elastic force of the spring mechanism. During use, when the bottom support assembly is subjected to the elastic force of spring 16, slide 26 moves upward, compressing spring 3 29. The restorative elastic force of the compressed spring 3 29 continues to push bottom support block 28 upward, preventing the blood sample tube 31 from being squeezed too quickly and thus alleviating the impact force on the blood sample tube 31.

[0050] An elastic buffer layer 30 and a blood sample tube 31 are sequentially provided on the inner wall of the placement hole 8. The contact surface between the elastic buffer layer 30 and the blood sample tube 31 is a smooth surface. The elastic buffer layer 30 facilitates the fixation of the blood sample tube 31, while the smooth surface facilitates the placement and removal of the blood sample tube 31.

[0051] The position-limiting assembly includes a third slider 33, which is fixed to the outer corner of the support plate 5. A hollow column 34 is located below the third slider 33. A rod 35 is inserted into the hollow column 34. A spring 4 36 is installed between the rod 35 and the hollow column 34. A ball bearing 37 is installed at the bottom of the rod 35. A chute 38 is provided on the inner wall of the box 1 for the ball bearing 37 to slide. The chute 38 has six equidistant positioning slots 39. The position-limiting assembly prevents the support plate 5 from rotating due to external impacts during transportation and facilitates quick and accurate positioning of the placement rack 6. During use, when the ball bearing 37 rotates to the positioning slot 39, the placement rack 6 is directly below the opening 3.

[0052] A heat shield 40 is provided on the inner bottom wall of the box body 1, directly below the vertical rod 9. A fan 41 is housed within the heat shield 40, with the fan blades of the fan 41 positioned above the heat shield 40. A plurality of vents 42 are provided on the support plate 5 above the fan 41. A removable heat sink 43 is provided on the box body 1 below the heat shield 40. The arrangement of the fan 41 and the heat shield 40 ensures uniform distribution of cool air within the box body 1.

[0053] A temperature sensor 44 is provided on the front inner wall of the box 1, and a temperature display 45 and a control panel 46 are provided on the front of the box 1. The temperature sensor 44 is electrically connected to the temperature display 45. A refrigerator 47 and a battery 48 are also provided on the inner bottom wall of the box 1. The refrigerator 47 and the electric fan 41 are both electrically connected to the control panel 46. The battery 48 provides power for the electrical appliances in the box 1.

[0054] The specific implementation process is as follows: when the storage box is closed, the spring in the spring mechanism is in a compressed state, so that the blood sample tube 31 on the storage rack 6 is just stored in the box body 1. When it is necessary to intermittently take out the blood sample tube 31 from the storage box, the medical staff first rotates the knob 10, and the knob 10 can be fixedly connected to the vertical rod 9 through the transmission component, thereby achieving the purpose of rotating the support plate 5. The target storage rack 6 can be accurately positioned under the window through the limit component, and the sealing cover 4 is opened. The purpose of pressing the spring mechanism is achieved by pressing the blood sample tube 31. At this time, the elastic force of the middle spring of the spring mechanism pushes the bottom support The assembly moves upward along the placement rack 6, driving the blood sample tube 31 in the placement rack 6 to move upward, thereby making it convenient for medical staff to take the blood sample tube 31 in the box 1, and can reduce a large amount of air convection inside and outside the box 1, thereby improving the heat preservation effect; at the same time, when the blood sample tube 31 is placed intermittently, it is only necessary to rotate the idle placement rack 6 to the bottom of the opening 3; and when the blood sample tube 31 needs to be transported, the fixed connection between the knob 10 and the vertical plate is released by rotating the knob 10. Under the action of the limit assembly, it is not easy for the box 1 to rotate, which can prevent the placed blood from being centrifuged and affecting the test results.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
