The action portion 12 is typically a blade, saw blade, 30700bar, chisel, and the action portion 12 is the sharp end of the medical instrument 1.

Between the operation portion 11 and the operation portion 12, a reducing portion 13 is generally formed, and the reducing portion 13 is a portion having a diameter gradually decreasing from the handle to the blade, and since the handle is thick and the handle, 30700 x and the blade are long and narrow, the reducing portion 13 is generally necessarily present in the medical device 1.

This embodiment is applied to the medical device 1 having the operation portion 11, the operation portion 12, and the diameter-changing portion 13.

As shown in fig. 1 to 7, embodiment 1 of a sharp medical instrument housing device is provided to solve the technical problem of how to house a medical instrument 1, wherein the medical instrument 1 is exemplified by nasal bone , and the main structure of embodiment 1 includes: package 2, package 3 and heat shrink 4.

The packaging bag 2 is provided with an inner cavity for placing the medical instrument 1, a gap for allowing steam to pass through is reserved between the inner cavity and the medical instrument 1, the inner cavity is divided into a first chamber 21, a second chamber 22 and a third chamber 23 along the length direction of the packaging bag 2, an opening 211 for allowing a steam spray pipe to pass through is arranged on the first chamber 21, and the opening 211 is used for sealing the packaging bag 2 through a hot-pressing sealing machine after the inner cavity is subjected to steam sterilization;

the packing box 3 has rigidity and is fixedly connected with the packing bag 2, so that the shape of the inner cavity of the packing bag 2 is fixed when no external force acts;

the heat shrinkage piece 4 is made of a material which shrinks when being heated, the shrinkage temperature of the heat shrinkage piece 4 is close to and smaller than the temperature of steam input into the inner cavity by the steam spray pipe, the heat shrinkage piece 4 is attached to and connected with the inner wall or the outer wall of the second cavity 22, and when the inner cavity is filled with steam, the heat shrinkage piece 4 is heated and shrinks the second cavity 22 to enable the second cavity 22 to pinch the medical instrument 1 so as to prevent the medical instrument 1 from shaking in the packaging bag 2.

Specific:

the packaging bag 2 is used for accommodating the medical device 1, wherein a first chamber 21 is used for accommodating the action part 12, a second chamber 22 is used for accommodating the reducing part 13, and a third chamber 23 is used for accommodating the operation part 11.

The packing box 3 is used to fix the edges of the packing bag 2 so that the packing bag 2 can maintain an original shape, for example, the packing bag 2 is a rectangular packing bag, and the packing bag 2 can always maintain a rectangular shape with the packing box 3 fixed.

The steam spray pipe and the hot-pressing sealing machine are components in the steam sterilizing machine of the medical equipment, the packaging bag with the medical equipment is transmitted through the transmission component, when the packaging bag passes through the steam spray pipe, the steam spray pipe is inserted into the packaging bag, steam is introduced into the packaging bag, so that the packaging bag and the medical equipment in the packaging bag can be sterilized, when the steam spray pipe is withdrawn after the sterilization is finished, and before the door of the steam sterilizing machine is opened, the mouth of the packaging bag is sealed by the hot-pressing sealing machine.

The heat shrinkage piece 4 can adopt a heat shrinkage pipe, and the shrinkage proportion of the heat shrinkage pipe is 2:1, the shrinkage temperature is 84 ℃ to 120 ℃, the working temperature is-55 ℃ to 125 ℃, the diameter of the heat shrinkage piece 4 is not reduced before being heated to a specified temperature, and a sufficient gap is formed between the medical instrument 1 and the packaging bag 2, so that steam can pass through and the medical instrument 1 can be sufficiently disinfected.

During steam sterilization, heat from the steam is transferred through the package 2 to the heat shrink 4, and as the temperature of the steam approaches and is greater than 100 ℃, the shrink temperature of the heat shrink 4 is less than 100 ℃, the heat shrink 4 shrinks by heat to create a motive force to pinch the second chamber 22.

On the premise that the initial shape of the packaging bag 2 is unchanged, the positions of the first chamber 21, the second chamber 22 and the third chamber 23 are not changed, so that the positions of the operating part 11 and the reducing part 13 are fixed, and the position of the operating part 12 is also fixed, so that the packaging bag 2 can be prevented from being punctured due to shaking of the operating part 12 in the packaging bag 2, and the sealing failure is caused.

In the above embodiment, the shrinkage time of the heat shrinkable member 4 cannot be too early or too late.

If the heat shrink 4 shrinks at a low temperature, the second chamber 22 tightens the medical device 1 immediately after the steam is introduced into the inside of the packing bag 2, so that the contact portion of the medical device 1 with the second chamber 22 cannot be sufficiently steam-sterilized.

If the heat shrink 4 shrinks at a higher temperature, i.e., the heat shrink 4 cannot be shrunk by the steam, the medical device 1 may shake inside the packaging bag 2 when the transmission is continued in the steam sterilizer through the transmission assembly after the packaging bag 2 is sterilized by the steam, resulting in the medical device 1 easily puncturing the packaging bag 2.

Therefore, the shrinkage temperature of the heat shrinkable member 4 must be close to and lower than the temperature of the steam, and the shrinkage temperature of the heat shrinkable member 4 is preferably 90 to 100 ℃.
