[0043] In the following description, many technical details are provided to help readers better understand the present application. However, those skilled in the art can understand that the technical solution claimed in the present application can be implemented even without these technical details and various changes and modifications based on the following embodiments.
[0044] To make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that these are only some examples that the present invention may take for the reader, but are not intended to limit the scope of the present invention.
[0045] The present application provides a cleaning device for allogeneic bone materials, comprising: a cleaning container 1, a sewage tank 2, a nozzle 3 and a pressurizing device. The pressurizing device is configured so that the water provided by the nozzle 3 is pressurized water. The cleaning container 1 is configured to accommodate allogeneic bone to be cleaned and receive the pressurized water provided by the nozzle 3; the cleaning container 1 comprises an overflow portion 11 and a receiving portion 12 located below the overflow portion 11, the overflow portion 11 is provided with a plurality of overflow holes 111, the overflow holes 111 are configured to allow the sewage in the cleaning container 1 to overflow into the sewage tank 2 and to block the allogeneic bone material from flowing out of the overflow holes 111 to the outside of the cleaning container 1.
[0046] In one embodiment, the allogeneic bone is in the form of granules, blocks or strips; and / or the amount of allogeneic bone is at a height of 1 / 2 of the depth of the receiving portion of the cleaning container 1. Since the allogeneic bone material is relatively light and the cleaning time of the allogeneic bone material is as long as 8 hours, it is easy to overflow from the cleaning container to the outside under the action of the water flow during the cleaning. In this case, the overflowed allogeneic bone material cannot be used. Therefore, an overflow portion 11 is provided, and the overflow hole 111 in the overflow portion 11 is designed to, on the one hand, block the allogeneic bone in the cleaning container 1 from being discharged to the outside of the cleaning container 1 with the water flow, and on the other hand, facilitate the sewage at the bottom of the cleaning container to flow upward and overflow to the outside of the clean water container under the action of the jet water flow. Preferably, the diameter of the overflow hole 111 is designed to prevent the allogeneic bone from flowing out of the overflow hole 111 to the outside of the cleaning container 1. More preferably, the diameter of the overflow hole 111 can be 2mm-4mm.
[0047] Preferably, the overflow portion 11 is an overflow portion that expands outward from the upper end surface of the receiving portion 12, the overflow portion that expands outward has a first diameter and a second diameter, and the receiving portion 12 has a third diameter, wherein the first diameter is the maximum diameter of the overflow portion 11, the second diameter is the minimum diameter of the overflow portion 11, and the third diameter is the maximum diameter of the receiving portion 12, the first diameter is greater than the second diameter and the third diameter, and the second diameter is less than or equal to the third diameter. Preferably, the receiving portion 12 has a cylindrical shape.
[0048] In an embodiment, the first diameter is in the range of 350 mm-550 mm, and / or the second diameter is in the range of 250 mm-350 mm, and / or the third diameter is in the range of 250 mm-350 mm.
[0049] In one embodiment, the nozzle 3 is configured to provide a conical-shaped water jet to the cleaning container 1. When the water jet falls in the cleaning device, the water jet tumbles, so that the allogeneic bone tumbles in the water with the water jet, so that the allogeneic bone is fully in contact with the water, which can reduce the cleaning time; in the highest liquid level of the cleaning device, the area of the water jet tumbling accounts for 1 / 2-2 / 3 of the area of the highest liquid level of the cleaning device. When the water jet falls on the highest liquid level, the bursting of bubbles helps to remove impurities and biological materials (such as immunogenic substances and bone marrow) remaining on the surface of the allogeneic bone.
[0050] Preferably, the pressure of the pressurized water just leaving the outlet end of the nozzle is 0.2 MPa, and the pressurized water helps to form the jet flow.
[0051] Preferably, the distance between the spray head 3 and the highest point of the cleaning container 1 is 30 mm-50 mm.
[0052] Preferably, the overflow portion 11 and the accommodating portion 12 are integrally formed, and the overflow portion is provided with a plurality of overflow holes 111, which helps the water in the cleaning container 1 to undergo a strong water flow exchange, i.e., sewage flows out from the overflow holes 111, and clean water enters the cleaning container.
[0053] Preferably, the height of the overflow portion 11 is 70 mm to 160 mm, and the height of the receiving portion 12 is 80 mm to 180 mm. The depth of the receiving portion 12 should not be too deep, which is conducive to the flow and exchange of water.
[0054] Preferably, because the allogeneic bone material needs to be flushed with rapid water for 8 hours continuously, which will generate a large amount of waste water, the sewage tank 2 is connected to a sewage treatment tank, so the waste water discarded through the sewage tank needs to be treated in the sewage treatment tank before being discharged or hauled away in a centralized manner.
[0055] A large number of technical features are recorded in the specification of this application, which are distributed in various technical solutions. If all possible combinations of technical features of this application (i.e., technical solutions) are to be listed, the specification will be too long. In order to avoid this problem, the various technical features disclosed in the above-mentioned utility model content of this application, the various technical features disclosed in the various embodiments and examples below, and the various technical features disclosed in the accompanying drawings can be freely combined with each other to form various new technical solutions (these technical solutions are all deemed to have been recorded in this specification), unless the combination of such technical features is technically infeasible. For example, in one example, feature A+B+C is disclosed, and in another example, feature A+B+D+E is disclosed, and features C and D are equivalent technical means that play the same role. Technically, only one can be used, and it is impossible to use them at the same time. Feature E can be combined with feature C technically. Then, the solution of A+B+C+D should not be deemed to have been recorded because it is technically infeasible, and the solution of A+B+C+E should be deemed to have been recorded.
[0056] All documents mentioned in this application are considered to be included in the disclosure of this application as a whole, so that they can be used as the basis for modification when necessary. In addition, it should be understood that after reading the above disclosure of this application, those skilled in the art can make various changes or modifications to this application, and these equivalent forms also fall within the scope of protection claimed in this application.
