Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood product storage device. Background Art

[0002] Platelets are small pieces of cytoplasm that fall off from the cytoplasm of mature megakaryocytes in the bone marrow. Although megakaryocytes are the smallest hematopoietic cells in the bone marrow, accounting for only 0.05% of the total number of nucleated cells in the bone marrow, the platelets they produce are extremely important for the body's hemostatic function.

[0003] In blood stations, it is often necessary to use a transport device to transport platelet mixtures. Existing transport boxes do not have a shaking function, and platelets are in a static state. Platelets will aggregate and lose their coagulation function if they remain static for a long time. Therefore, a storage device that can shake platelets is urgently needed. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a blood product storage device, which can solve the problem that the transport box has no shock function.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] A blood product storage device includes a support frame, an oscillation cylinder and an oscillation assembly. The oscillation cylinder is used to install a test tube. The oscillation cylinder can be movably arranged on the support frame. A transmission column is arranged at the bottom end of the oscillation cylinder. The transmission column is transmission-connected to the oscillation assembly. The oscillation assembly is used to drive the oscillation cylinder and the transmission column to oscillate.

[0007] In the present application, a support frame is provided to support the oscillation cylinder, and the oscillation cylinder is shaken by a transmission column, which can drive the test tube in the oscillation cylinder to oscillate, shake the platelets, and prevent the platelets from aggregation.

[0008] Furthermore, the oscillation component includes a base, a chassis and a driving mechanism, the chassis is rotatably connected to the base, the driving mechanism is used to drive the chassis to rotate, a first ring body and a second ring body are concentrically arranged on the chassis, a channel for the transmission column to slide is formed between the first ring body and the second ring body, and multiple protrusions are arranged on the inner walls on both sides of the channel. When the protrusions rotate with the chassis to pass through the transmission column, they can drive the oscillation tube to shake.

[0009] In the present application, as the first ring body and the second ring body rotate with the chassis, the protrusions can continuously collide with the transmission column and drive the transmission column and the oscillation cylinder to shake, thereby ensuring that during the storage process, the platelets are always in an oscillating state and will not aggregate.

[0010] Furthermore, the protrusions are staggered, the size difference between the inner diameter of the protrusion on the first ring body and the outer diameter of the protrusion on the second ring body is smaller than the diameter of the transmission column, and the size between the protrusion on the first ring body and the adjacent protrusion on the second ring body is larger than the diameter of the transmission column.

[0011] In the present application, the position of the protrusion is limited so that the transmission column will not pass through two protrusions at the same time, causing the transmission column to be stuck, thereby ensuring the vibration effect of the protrusion on the transmission column, and the diameter of the transmission column is limited to increase the frequency of the protrusion colliding with the transmission column, thereby ensuring the vibration effect.

[0012] Furthermore, the driving mechanism includes gears and a motor, the chassis is provided with teeth on its circumference, the gears are meshed with the teeth, and the gears are transmission-connected to the motor.

[0013] In the present application, a motor and gears are provided to drive the chassis to rotate, and the platelets do not need to be manually shaken, the degree of automation is high, and the shaking effect is good.

[0014] Furthermore, it also includes a box body and a box cover, wherein the box body and the box cover are used to contain and seal the oscillation component, the oscillation cylinder and the support frame, and the box cover can be connected to the box body in an openable and closable manner.

[0015] Furthermore, the support frame is fixed on the base, and a support plate is provided on the support frame corresponding to the oscillation cylinder. A through hole is provided on the support plate for the transmission column to pass through, and a diameter of the through hole is larger than a diameter of the transmission column.

[0016] Furthermore, it also includes a limit frame, which is fixed on the base, and the limit frame is provided with a limit ring corresponding to the position of the oscillation tube. The limit ring is arranged on the periphery of the oscillation tube, and the inner diameter of the limit ring is larger than the outer diameter of the oscillation tube.

[0017] In the present application, in order to prevent the oscillation tube from tilting or sliding, a limit frame is also provided on the base to limit the position of the oscillation tube, thereby limiting the tilt angle of the oscillation tube and ensuring the oscillation effect.

[0018] Furthermore, the limiting rings and the supporting plates are provided in multiple groups.

[0019] In the present application, multiple groups of limit rings and support plates are provided to accommodate multiple groups of oscillation tubes, thereby oscillating multiple groups of platelets at the same time, which is highly practical.

[0020] Beneficial effects of the utility model:

[0021] 1. In the present application, a support frame is provided to support the oscillation cylinder, and the oscillation cylinder is shaken by a transmission column, which can drive the test tube in the oscillation cylinder to oscillate, shake the platelets, and prevent the platelets from aggregating.

[0022] 2. In the present application, when the first ring body and the second ring body rotate with the chassis, the protrusions can continuously collide with the transmission column and drive the transmission column and the oscillation cylinder to shake, thereby ensuring that the platelets are always in an oscillating state during the storage process and will not aggregate.

[0023] 3. In the present application, the position of the protrusion is limited so that the transmission column will not pass through two protrusions at the same time, causing the transmission column to be stuck, thereby ensuring the vibration effect of the protrusion on the transmission column, and the diameter of the transmission column is limited to increase the frequency of the protrusion colliding with the transmission column to ensure the vibration effect.

[0040] like Figure 1-2 As shown, the present application provides a blood product storage device, including a support frame 1, an oscillation cylinder 2 and an oscillation assembly 3. The support frame 1 is used to support the oscillation cylinder 2, and the oscillation cylinder 2 is used to hold a test tube containing platelets. The oscillation assembly 3 is used to shake the oscillation cylinder. The bottom end of the oscillation cylinder 2 is covered. The bottom end of the oscillation cylinder 2 is provided with a transmission column 21. The transmission column 21 is connected to the oscillation assembly 3. The oscillation assembly 3 can drive the transmission column 21 to swing so as to oscillate the oscillation cylinder 2.

[0041] The oscillation assembly 3 includes a base 38, a chassis 31 and a driving mechanism. The chassis 31 is rotatably connected to the base 38. The driving mechanism is used to drive the chassis 31 to rotate. A first ring body 32 and a second ring body 33 are concentrically arranged on the chassis 31. A channel 34 for the transmission column 21 to slide is formed between the first ring body 32 and the second ring body 33. A plurality of protrusions 35 are arranged on the inner walls on both sides of the channel 34. When the protrusions 35 rotate with the chassis 31 to collide with the transmission column 21, the oscillation tube 2 can be driven to shake. In the present application, the chassis 31, the protrusions 35 and other structures collide with the transmission column 21. In actual use, a plurality of driving mechanisms such as cylinders can be set to push the transmission column. The present application sets the chassis 31 and the protrusions 35, and the transmission column 21 is driven by the protrusions 35 to rotate. The structure is simple, the use cost is low, and the practicality is strong.

[0042] like Figure 3 In order to ensure that the protrusions 35 can collide with the transmission column 21, in the present application, the protrusions 35 are arranged in a staggered manner. The size difference between the inner diameter of the protrusions 35 on the first ring body 32 and the outer diameter of the protrusions on the second ring body 33 is smaller than the diameter of the transmission column 21. The size between the protrusions 35 on the first ring body 32 and the adjacent protrusions 35 on the second ring body 33 is larger than the diameter of the transmission column 21. The protrusions 35 on the first ring body 32 and the protrusions on the second ring body 33 are arranged alternately, which can ensure that when the transmission column 21 slides in the channel 34, it can collide with each protrusion 35, thereby improving the shock effect.

[0043] The driving mechanism includes a gear 36 and a motor. The chassis 31 is provided with teeth on the periphery. The gear 36 meshes with the teeth. The gear 36 is connected to the output shaft of the motor. When the motor drives the gear 36 to rotate, the chassis 31 can be driven to rotate. The motor can also be connected to the chassis by a belt connection or direct drive, thereby driving the chassis 31 to rotate. The present application sets the gear 36 and the teeth to drive the chassis, which is practical and easy to maintain.

[0044] To improve the sealing of the device and ensure a sterile environment, Figure 1 The blood product storage device further comprises a box body 5 and a box cover 6. The box body 5 and the box cover 6 are used to contain and seal the oscillation assembly 3, the oscillation cylinder 2 and the support frame 1. The box cover 6 is openably connected to the box body 5. A freezing assembly is also provided in the box body 5 for facilitating the storage of platelets, and is used to reduce the temperature in the box body 5.

[0045] The support frame 1 is fixed on the base 38, and a support plate 11 is provided at the support frame 1 corresponding to the oscillation cylinder 2. The support plate 11 is provided with a through hole for the transmission column 21 to pass through, and the diameter of the through hole is larger than the diameter of the transmission column 21. The support frame 1 is only used to support the oscillation cylinder 2 and will not limit the shaking of the oscillation cylinder.

[0046] In the present application, in order to prevent the oscillation tube 2 from tilting or sliding, a limiting frame 7 is further provided on the base 38 to limit the oscillation tube 2. Specifically, the limiting frame 7 is provided with a limiting ring 71 corresponding to the position of the oscillation tube 2, and the limiting ring 71 is provided on the circumference of the oscillation tube 2, and the inner diameter of the limiting ring 71 is greater than the outer diameter of the oscillation tube 2.

[0047] Preferably, the support frame 1 and the limiting frame 7 can also be fixed on the box body 5 .

[0048] In the present application, the limiting ring 71, the support plate 11 and the oscillation tube 2 can be arranged into multiple groups, so that multiple test tubes can be oscillated simultaneously, which is practical.

[0049] In this embodiment, Figure 4-6 The box body 5 can also be configured as a multifunctional box with multiple areas, and each area is provided with a drawer for conveniently storing and placing items in each area. The box body includes a first area 51, a second area 52, a third area 53 and a fourth area 54. The first area 51 is used to accommodate the above-mentioned oscillation component 3. An oscillation mechanism for oscillating the blood bag is arranged in the second area 52. The oscillation mechanism includes a drawer 80, a motor 81, a drive disk 82, an oscillation disk 83 and a receiving disk 84. The motor 81 is fixed in the drawer 80. The drive disk 82 is coaxially fixed at the output end of the motor 81. A plurality of protrusions are arranged on the drive disk 82. A bracket 85 for receiving the receiving disk 84 is arranged in the drawer 81. The bracket 85 is used to arrange the receiving disk 84 above the drive disk 82. An oscillation disk 83 is arranged at the bottom of the receiving disk 84. A protrusion is arranged on the side of the oscillation disk 82 close to the drive disk 83. When the driving disk 82 rotates, the protrusion on the driving disk 83 encounters the protrusion on the oscillating disk 83, which can lift up the oscillating disk 83 and the containing disk 84, thereby achieving the purpose of driving the containing disk 84 to oscillate.

[0050] The third area 53 and the fourth area 54 are used for temporarily storing other blood components such as red blood cells, plasma, etc. The device can simultaneously store blood by classification. Preferably, a temperature control component is provided in the box 5 to maintain the low temperature environment required for temporary storage of blood.

[0051] Preferably, a handle is provided on the box body 5 for convenient carrying of the box body 5 .

[0052] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
