[0024] The following combination Figure 1-Figure 3 The present invention describes a disposable sterile consumable and an installation method.

[0025] The disposable sterile consumables provided by the embodiment of the present invention include a consumable main body 1 and a flexible part 2. An installation cavity 11 is provided inside the consumable main body 1, and the installation cavity 11 passes through the consumable main body 1. The length of the installation cavity 11 is greater than the length of the installation shaft 6, and the installation cavity is used to accommodate the installation shaft 6. One end of the installation shaft 6 is inserted into the installation cavity 11, and the outer wall surface of the installation shaft 6 is in close contact with the inner wall surface of the installation cavity 11. There is a gap between the top of the installation shaft 6 and the top of the installation cavity 11; the other end of the installation shaft 6 is used to connect with the medical device. In order to ensure airtightness, the outer wall surface of the installation shaft 6 and the inner wall surface of the installation cavity 11 are both highly polished. It should be noted that the consumable main body 1 is made of metal or other hard non-metallic materials, and the installation cavity 11 can be a cylindrical structure, such as Figure 1 As shown; it can also be a polygonal structure to meet different application requirements.

[0026] The flexible member 2 is located on top of the consumable body 1 and is used to adjust the gas pressure within the mounting cavity 11. Specifically, the flexible member 2 has a cavity 21 with a first opening and a second opening. The first opening is sealed and connected to the mounting cavity 11, while the second opening is connected to the external environment. The flexible member 2 is made of silicone or other soft non-metallic material, and the pressure within the mounting cavity 11 can be adjusted by manual squeezing.

[0027] During installation, the flexible member 2 is squeezed, and the gas in the installation cavity 11 is discharged outward until the inner wall of the cavity 21 is in contact, thereby disconnecting the installation cavity 11 from the second opening. During this process, the pressure in the installation cavity 11 decreases, forming a negative pressure environment, and the installation shaft 6 is stably installed in the installation cavity 11.

[0028] When the installation shaft 6 needs to be removed, the user can squeeze the flexible part 2 again, and the extrusion direction can be perpendicular to the extrusion direction during installation, so that the inner wall of the second opening of the cavity 21 is separated, thereby connecting the second opening with the installation cavity 11, and the outside air enters the installation cavity 11, and the normal atmospheric pressure in the installation cavity 11 is restored. In the absence of a pressure difference, the installation shaft 6 can be quickly removed and replaced with the help of external force.

[0029] The disposable sterile consumables provided in the embodiment of the present invention can expel the gas in the installation cavity by squeezing the flexible part, reduce the pressure in the installation cavity, and quickly fix the installation shaft in the installation cavity; squeezing the flexible part to allow outside air to enter the installation cavity, restore the pressure in the installation cavity, and quickly remove the installation shaft, saving time and effort.

[0030] The disposable sterile consumables also include a flexible switch member 3, which is provided at the top of the flexible member 2. The state of the second opening can be precisely controlled manually, thereby adjusting the gas pressure in the installation cavity 11. If the flexible switch member 3 is an annular elastic member, the annular elastic member surrounds the second opening and is used to open and close the second opening. In the initial state, the annular elastic member is in a closed state, that is, the inner wall of the annular elastic member fits together, thereby closing the second opening, forming a sealed environment in the installation cavity 11, and stably fixing the installation shaft 6 in the installation cavity 11. When it is necessary to adjust the gas pressure in the installation cavity 11, the pressure in the installation cavity 11 can be discharged through the annular elastic member by manually squeezing the flexible switch member 3; applying an opposite force to squeeze the annular elastic member will cause the annular elastic member to be ejected by the external force, and the second opening will open accordingly. When the annular elastic member is ejected and the second opening is connected to the annular elastic member, external gas can enter the installation cavity 11 through the annular elastic member and the second opening. The annular elastic member can be a silicone member.

[0031] In a specific embodiment, Figure 1 and Figure 2 As shown, the flexible switch member 3 includes a first opening and closing portion 31 and a second opening and closing portion 32. The bottom of the first opening and closing portion 31 and the bottom of the second opening and closing portion 32 surround the second opening, forming the sidewalls of the gas channel. The bottoms of the first opening and closing portion 31 and the bottoms of the second opening and closing portion 32 are respectively connected to the flexible member 2, ensuring a seal between the flexible switch member 3 and the flexible member 2. The first side of the first opening and closing portion 31 is connected to the first side of the second opening and closing portion 32, and the second side of the second opening and closing portion 32 is connected to the second side of the second opening and closing portion 32. The first opening and closing portion 31 is tilted upward toward the second opening and closing portion 32, and the second opening and closing portion 32 is tilted upward toward the first opening and closing portion 31. The spacing between the first opening and closing portion 31 and the second opening and closing portion 32 gradually decreases from bottom to top until the top of the first opening and closing portion 31 and the top of the second opening and closing portion 32 are in contact. In other words, the first opening and closing portion 31 and the second opening and closing portion 32 form a gas channel that communicates with the cavity 21. It should be noted that the gas channel is in a closed state and can be separated under the action of an external force. The second opening can be opened to discharge the gas in the installation cavity 11 or allow external gas to enter the installation cavity.

[0032] During the installation process, an external force can be applied along the first direction toward the first opening and closing portion 31 and the second opening and closing portion 32, and the gas in the installation cavity 11 can be discharged through the space between the first opening and closing portion 31 and the second opening and closing portion 32. It should be noted that, under the action of the extrusion force, the external gas cannot enter the installation cavity at this time, and a negative pressure is formed in the installation cavity 11. The installation shaft 6 is fixed in the installation cavity 11 by the principle of negative pressure adsorption. During the disassembly process, an external force can be applied along the second direction toward the first opening and closing portion 31 and the second opening and closing portion 32. The distance between the first opening and closing portion 31 and the second opening and closing portion 32 gradually increases, the second opening is connected to the outside air, and the pressure in the installation cavity 11 returns to normal. In the absence of a pressure difference, the installation shaft 6 can be quickly removed under the action of an external force. In one embodiment, the first direction and the second direction are perpendicular, and the first direction is perpendicular to the interface between the first opening and closing portion 31 and the second opening and closing portion 32.

[0033] The flexible switch member 3 and the flexible member 2 in the embodiment of the present invention may be an integrally formed member, and the integrally formed member may be a silicone member.

[0034] The disposable sterile consumable also includes a first seal 4, which is removably sealed at the second opening. The seal is used to ensure a stable negative pressure environment within the installation cavity 11 during installation. In one embodiment, the first seal 4 is a blocking member. When the pressure within the installation cavity 11 reaches a negative pressure, the blocking member can be used to block the second opening. In this case, no manual operation is required, and the installation shaft 6 can be stably fixed within the installation cavity 11.

[0035] In another embodiment, the second sealing member 5 includes a snap-fitting portion and a matching portion. The snap-fitting portion is provided on a side of the first opening / closing portion 31 near the second opening / closing portion 32, and the matching portion is provided on a first side of the second opening / closing portion 32 near the first opening / closing portion 31. The snap-fitting portion can be snapped into the matching portion, achieving a sealed connection between the first opening / closing portion 31 and the second opening / closing portion 32, thereby maintaining a negative pressure environment within the mounting cavity 11. If the mounting shaft 6 needs to be removed, the snap-fitting portion is separated from the matching portion, and atmospheric pressure is restored within the mounting cavity 11. The mounting shaft 6 can then be removed under the action of an external force.

[0036] In yet another embodiment, one of the first opening and closing portion 31 and the second opening and closing portion 32 is provided with a magnetic member, and the other is provided with a magnetic adsorption member. The adsorption between the magnetic member and the magnetic adsorption member enables a seal between the first opening and closing portion 31 and the second opening and closing portion 32, thereby sealing the second opening. When the mounting shaft 6 needs to be removed, the magnetic member and the magnetic adsorption member are separated by external force, thereby opening the second opening and restoring normal atmospheric pressure. In another embodiment, one of the first opening and closing portion 31 and the second opening and closing portion 32 is provided with an adhesive member, and the other is provided with an adsorption member. The adhesive member and the adsorption member can adhere and separate under the action of an external force.

[0037] The disposable sterile consumables also include a second seal 5, which is arranged between the top surface of the consumable body 1 and the flexible part 2, forming an additional sealing barrier on the top surface of the consumable body 1 to prevent gas leakage. In one embodiment, the second seal 5 can be fixed on the top surface of the consumable body 1 by bonding with a sealant to ensure the stability and sealing of its position. The second seal 5 is transitionally connected to the flexible part 2, and the transition connection ensures the sealing from the flexible part 2 to the top surface of the consumable body 1 to prevent gas leakage from the joint. The size of the second seal 5 is larger than the cross-sectional size of the installation cavity 11, and the second seal 5 can cover the periphery of the second opening of the installation cavity 11, and the sealing effect is good. It should be noted that a through hole is provided on the second seal 5 for connecting the installation cavity 11 and the cavity 21 to achieve gas exchange, thereby adjusting the gas pressure in the installation cavity 11.

[0038] In the embodiment of the present invention, the second sealing member 5 and the flexible member 2 are an integrally formed member, and the integrally formed member can be a silicone member.

[0039] In one embodiment, the second sealing member 5, the flexible member 2, and the flexible switch member 3 are integrally formed. Figure 1 As shown, the integrally formed part can be a silicone part.

[0040] The flexible member 2 in the embodiment of the present invention is a spherical structural member, such as Figure 1 As shown, the flexible member 2 is an airbag with a spherical structure.

[0041] In one embodiment, the cross section of the installation cavity 11 is circular, and the installation shaft 6 is a column, so that the installation shaft 6 can be installed at any angle, thereby increasing the installation speed. The cross section of the installation cavity 11 can be polygonal.

[0042] Furthermore, the cross-sectional area of ​​the installation cavity 11 in the embodiment of the present invention gradually decreases from the bottom to the top, and correspondingly, the cross-sectional area of ​​the installation shaft 6 gradually increases from the insertion end to the other end, matching the installation cavity 11 to prevent scratches during the installation process. Figure 2 As shown, the cross section of the installation cavity 11 is circular, and the cross section of the installation cavity 11 gradually decreases from the bottom to the top, that is, the installation cavity 11 is a tapered structure.

[0043] It should be noted that the mounting shaft 6 in the embodiment of the present invention includes an insertion section and a connecting section. The insertion section is installed in the mounting cavity 11, and the connecting section is connected to the medical device. The maximum cross-section of the insertion section is smaller than the minimum cross-section of the connecting section, forming a step, and there is a distance between the step and the consumable body 1.

[0044] The present invention is applicable to various application scenarios of medical devices.

[0045] Based on the disposable sterile consumables in any of the above embodiments, the present invention also provides a method for installing the disposable sterile consumables, such as Figure 3 As shown, the method includes step 100 of inserting a mounting shaft connected to the medical device into the mounting cavity, wherein the outer wall of the mounting shaft is tightly aligned with the inner wall of the mounting cavity, and a gap exists between the top of the mounting shaft and the top of the mounting cavity. Step 200 of squeezing the flexible member to reduce the pressure in the mounting cavity and secure the mounting shaft in the mounting cavity. Specifically, the flexible member is squeezed to expel the gas in the mounting cavity until the pressure inside and outside the mounting cavity is balanced. The second opening of the flexible member closes under the elastic recovery force of the flexible member, disconnecting the mounting cavity from the outside world. After this process, the pressure in the mounting cavity is reduced, forming a negative pressure environment, and the mounting shaft is stably installed in the mounting cavity under the action of atmospheric pressure. Step 300 of squeezing the flexible member in a direction different from the squeezing direction during installation, separating the inner wall of the second opening of the flexible member, thereby connecting the mounting cavity to the outside world and allowing outside air to enter the mounting cavity. Normal atmospheric pressure is restored in the mounting cavity. In the absence of a pressure difference, the mounting shaft can be quickly removed with the help of external force. It should be noted that the direction of the squeezing force can be adjusted according to the structure of the flexible member. In one embodiment, the squeezing direction during installation is perpendicular to the squeezing direction during removal. The embodiment of the present invention utilizes the negative pressure principle to achieve quick installation and disassembly, saving time and effort.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
