Description

Technical Field

[0001] This utility model belongs to the technical field of material drying equipment, and in particular relates to a drying device for allogeneic bone materials. Background Technology

[0002] Allogeneic bone is a common medical concept referring to bone tissue from different individuals within the same species. It undergoes a series of complex processing steps, including but not limited to defatting, decellularization, and sterilization, to preserve the bone's natural three-dimensional structure and some of its bioactive components. This results in good osteoconductivity and osteoinductive properties, effectively promoting the regeneration and reconstruction of the host bone tissue. In medical practice, allogeneic bone is primarily used in orthopedic surgeries, such as fracture repair and bone defect repair.

[0003] As an implant material, the production process of allogeneic bone requires cutting and cleaning. In particular, after the allogeneic bone is cut, it is necessary to rinse away any remaining impurities and biological materials (such as immunogenic substances, such as bone marrow). According to requirements, the allogeneic bone needs to be rinsed for at least 10 hours, and then dried to remove water stains attached to the surface of the bone plate. It is then vacuum-packed and frozen at low temperature. It can only be removed and implanted into the human body during surgery to prevent serious rejection, infection and other adverse situations.

[0004] Existing washing and drying devices are separate units. In actual operation, the bone material is removed and transferred to the drying device after washing. Due to the different sizes of the bone implants, it is inconvenient to remove them after washing, making the operation cumbersome, time-consuming and labor-intensive. In addition, the existing drying devices have limited functions, only performing single spin-drying or drying operations, resulting in poor drying effects. Therefore, there is an urgent need to design a drying device for allogeneic bone materials. Utility Model Content

[0005] This invention provides a reasonably structured drying device for allogeneic bone materials to address the technical problems existing in prior art. This invention integrates rinsing and drying functions, is simple to operate, and can simultaneously spin-dry and bake bone implant materials, resulting in good drying effect and high work efficiency.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: an allogeneic bone material drying device includes a mounting support, on which a box structure with an openable top is mounted; an outer rotating cage assembly is rotatably connected to the inner cavity of the box structure, and a rotary drive assembly for driving the outer rotating cage assembly to rotate is provided; multiple storage cavities are provided on the outer rotating cage assembly, evenly distributed circumferentially, and each storage cavity is provided with a storage basket detachably connected to the outer rotating cage assembly; an inner partition assembly is provided at the center of the outer rotating cage assembly, fixedly connected to the box structure, and the inner partition assembly is provided with partition cavities distributed circumferentially and corresponding one-to-one with the multiple storage cavities; it also includes a rinsing structure and a drying structure; the rinsing structure includes a... The system includes a wastewater tank, a clean water tank, and a water pump mounted on a support. The clean water tank is connected to the water pump via a liquid pipeline, and the wastewater tank is connected to a waste liquid outlet located at the bottom of the tank structure via a liquid pipeline. The inner cavity of the inner partition assembly is divided into two chambers, left and right. Several liquid distribution pipes connected to the water pump are installed in the left chamber, and the outlets of the liquid distribution pipes pass through the left chamber and are located in one of the partition chambers of the inner partition assembly. The drying structure includes a blower mounted on the support, the blower's outlet being connected to the right chamber of the inner partition assembly via a gas pipeline, and an air outlet hood fixed in another partition chamber of the outer rotating drum assembly, which is connected to the right chamber of the inner partition assembly via a gas pipeline. The water pump is connected to the drying air source via a gas pipeline.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides an allogeneic bone material drying device. By setting an outer rotating cage assembly with several storage cavities, several storage baskets can be easily hooked, facilitating the loading and unloading of allogeneic bone materials, and the operation is simple. A rotating drive assembly drives the outer rotating cage assembly to rotate, causing the storage baskets and the bone materials inside to rotate with the outer rotating cage assembly, thus achieving the spin-drying operation of the washed bone materials. The washing structure washes the bone materials in each storage basket rotating with the outer rotating cage assembly, and the drying structure injects drying gas into the housing structure, further drying the spin-dried bone materials, thus improving the drying effect of the allogeneic bone materials. This utility model integrates washing and drying functions, eliminating the need for intermediate bone material transfer, simplifying the operation process; and it can simultaneously perform spin-drying and drying operations on bone implant materials, resulting in good drying effect and high work efficiency.

[0027] Working principle:

[0028] In the actual work process, the staff put the aggregate into multiple storage baskets 8, and then put the multiple storage baskets 8 into multiple storage cavities one by one and hang them on the mounting frame 3-1 in the outer rotating cage assembly 3. At this time, the wedge-shaped abutment block 3-6 in the outer rotating cage assembly 3 can support and resist the storage baskets 8, and at the same time prevent the storage baskets 8 from flying out due to centrifugal force when rotating.

[0029] After placing each storage basket 8, close the lid 7, then start the drive motor 15-1 in the rotary drive assembly 15 to rotate the outer rotating cage assembly 3. Simultaneously, start the water pump 17 to pump the cleaning liquid from the clean water tank 14 into several distribution pipes 4 and 11 to rinse the aggregate in the storage baskets 8 that are rotating with the outer rotating cage assembly 3. The rinsed wastewater flows into the wastewater tank 1 through the waste liquid outlet 12. After a preset rinsing time, turn off the water pump 17, and the rotary drive assembly 15 continues to rotate the outer rotating cage assembly 3 to further clean the aggregate in each storage basket 8. Spin-drying operation: After a period of continuous spin-drying, blower 16 is turned on, and drying gas is blown into air outlet hood 19 and air outlet hood 2 18 respectively. Air outlet hood 19 and air outlet hood 2 18 spray drying gas in two directions toward the storage basket 8 between them, thereby further drying the aggregate that has been spin-dried and improving the drying effect. After the drying process is completed, drive motor 15-1 in rotary drive assembly 15 is turned off. After the outer rotating cage assembly 3 stops rotating, the box cover 7 is opened, and then each storage basket 8 is lifted out to take out and transfer the dried aggregate. The operation process is simple.
