It includes: an upper cover and a lower cover that are screwed together. The upper cover and the lower cover divide the memory into an upper cavity and a lower cavity through a locking switch; a magnetic stirrer is arranged in the lower cavity, and the magnetic stirrer is used to stir the liquid in the lower cavity; a first guiding limiting block and a limiting block are arranged on the surface of the groove of the upper cover, and a second limiting guiding block is arranged on the lower side of the sealing knob of the locking switch; when the locking switch is fully tightened, the second limiting guiding block enters between the first guiding limiting block and the limiting block to be clamped and limited. The beneficial effects are as follows: During disinfection, the bone tissue and the liquid are located in the lower cavity. After the disinfection is completed, the liquid completely enters the upper cavity, and the bone tissue remains in the lower cavity. Then, the locking switch is closed, and the first sealing member is opened to drain the liquid. Finally, the memory with the bone tissue is placed in a freezer. Throughout the process, the bone tissue does not come into contact with air, ensuring the sterilization effect.

Description

Technical Field

[0001] The present invention relates to the technical field of sterilization equipment, and particularly relates to a bone sterilization memory and a sterilization method using the same. Background Art

[0002] In the prior art, when human bone tissue is transferred and stored after sterilization, it will be exposed to the air, and the bone tissue will be contaminated again during this process. In addition, in the prior art, a disposable sterilization device cannot be stirred by itself before sterilization, which affects the sterilization effect, and the sealing effect of the memory is not good during the disinfection process, and liquid leakage is likely to occur.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a bone sterilization memory and a sterilization method using the same to solve the technical problems existing in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a bone sterilization memory, including: an upper cover and a lower cover that are screwed together, and the upper cover and the lower cover divide the memory into an upper cavity and a lower cavity through a locking switch; a magnetic stirrer is arranged in the lower cavity, and the magnetic stirrer is used to stir the liquid in the lower cavity; a first guiding and limiting block and a limiting block are arranged on the surface of the groove of the upper cover, and a second limiting and guiding block is arranged on the lower side of the sealing knob of the locking switch; when the locking switch is fully tightened, the second limiting and guiding block enters between the first guiding and limiting block and the limiting block to be clamped and limited.

[0006] In an optional embodiment, the first guiding and limiting block has a first inclined surface, and the second limiting and guiding block has a second inclined surface; in the same direction, the inclined directions of the first inclined surface and the second inclined surface are opposite.

[0007] In an optional embodiment, a storage rack is arranged in the lower cavity on the side wall of the lower cover, and the magnetic stirrer is arranged in the magnetic stirrer placement cavity.

[0008] In an optional embodiment, a first sealing member is arranged in the cavity opening of the upper cover; a second sealing member is arranged between the upper cover and the lower cover; a third sealing member is arranged between the upper cover and the sealing knob.

[0009] In an optional embodiment, the first sealing member is a rubber stopper, and the second sealing member and the third sealing member are sealing rings.

[0010] In an optional embodiment, a first guiding member is arranged on the upper part of the opening channel on the bottom wall of the upper cover, and a second guiding member is arranged on the lower part of the opening channel on the bottom wall of the upper cover.

[0011] In an alternative embodiment, the first guiding member is a plate-like structure with a central opening, and the second guiding member is a cylindrical rod.

[0012] In an alternative embodiment, a movable closing member is sleeved on the second guiding member. The movable closing member moves up and down along the second guiding member in the opening channel and the central opening of the first guiding member. There is a gap between the connecting portion of the central opening of the first guiding member and the movable closing member, and the liquid passes through the gap.

[0013] In an alternative embodiment, a threaded connecting portion is provided in the inner cavity of the connecting portion, and the threaded connecting portion is screwed with the threaded rod of the locking switch; the rotation of the locking switch drives the sealing plate of the movable closing member to move up and down to close or communicate the upper cavity and the lower cavity; when the upper cavity and the lower cavity are closed, the upper cover and the lower cover are sealed by a sealing gasket provided on the bottom wall of the upper cover or the upper surface of the sealing plate.

[0014] On the other hand, an embodiment of the present invention also provides a bone sterilization method, using the bone sterilization memory as described above, including the following steps:

[0015] S1: Place the qualified human bone tissue in the memory, fill the memory with lactated Ringer's solution or normal saline up to the upper scale line, and tighten the memory to completely enclose the liquid in the lower cavity;

[0016] S2: Start the magnetic stirrer to stir the liquid containing human bone tissue. After stirring evenly, place the memory in the heating and cooling system of the bone sterilization memory, and start the heating and disinfection program;

[0017] S3: After the heating and disinfection is completed, invert the memory, open the locking switch to drain the liquid into the upper cavity of the memory, and leave the human bone tissue in the lower cavity; wait until all the liquid flows into the upper cavity, close the locking switch tightly, take out or press the first sealing member in the upper cover into the upper cavity of the memory, and discharge the liquid through the opening of the upper cavity;

[0018] S4: Place the memory with bone tissue in a freezer and store it at a temperature below -70°C.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) During disinfection in the bone sterilization memory, the human bone tissue and the liquid are located in the lower cavity. After disinfection, the liquid completely enters the upper cavity, and the human bone tissue remains in the lower cavity. Then, close the locking switch, and then open or insert the first sealing member to drain the liquid. Finally, place the memory with human bone tissue in a freezer. Throughout the process, the human bone tissue does not come into contact with air, ensuring the sterilization effect.

[0021] (2) A magnetic stir bar is provided in the bone sterilization memory. Before sterilization, the liquid is stirred evenly to improve the sterilization effect. The memory is used once during sterilization, and the liquid is completely enclosed in the lower cavity. At this time, the second limit guide block enters and is clamped and limited between the first guide limit block and the limit block to prevent the locking switch from rotating and leaking liquid, ensuring the sterilization effect.
