DETAILED DESCRIPTION
[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific implementation methods. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0034] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.
[0035] An embodiment of the present utility model discloses a dual-chamber hydrogen peroxide plasma sterilizer (hereinafter referred to as a "sterilizer" for ease of explanation), in the hope that the disinfection and sterilization efficiency can be effectively improved when faced with a large number of medical devices to be disinfected and sterilized, while being able to fully disinfect and sterilize the internal flow path of the tubular medical device 100.
[0036] It is worth noting that the lumen medical device 100 described in this embodiment can be as follows: Figure 1 The endoscope or other similar medical devices shown in the figure. As for this type of tubular lumen medical device 100, in addition to including an internal flow path (not shown in the figure) for fluid to circulate therein, it also includes a plurality of inlets 101 and outlets 102 connected to the internal flow path. Among them, the inlet 101 is used to allow external fluid to enter the internal flow path, and the outlet 102 is used to allow the fluid flowing through the internal flow path to flow out. The specific structure of this type of tubular lumen medical device 100 can refer to the structure of the tubular lumen medical device 100 known in the prior art, and will not be elaborated on here.
[0037] like Figure 2 As shown in FIG, it shows the general structure of the exemplary sterilizer disclosed in this embodiment. Figure 2 In the sterilizer shown, the sterilizer may include two chambers 10 and a connecting pipe assembly 20 .
[0038] Combine Figure 2 and Figure 3 As shown, each chamber 10 defines a chamber 11 suitable for accommodating and sterilizing medical devices. It will be appreciated that the single chamber 10 described in this embodiment may have a substantially identical structure to that of a chamber 10 of a hydrogen peroxide plasma sterilizer known in the prior art, and that the two chambers 10 constituting the sterilizer disclosed in this embodiment may also have substantially the same structure.
[0039] Furthermore, the two chambers 10 can be arranged side by side in a direction to optimize the structural design of the sterilizer as much as possible. For example, the drawings of this embodiment show a situation where the two chambers 10 are arranged in a vertically overlapping manner. Of course, in other embodiments of the present invention, the arrangement of the two chambers 10 is not limited to this, and is not limited here.
[0040] like Figure 2 As shown, at least one cabin 10 is provided with a vacuum port 12 and a sterilization medium flow port 13 that communicate with its own cabin 11. The vacuum port 12 can be connected to an external vacuum device (not shown in the figure) so that the cabin 11 of the cabin 10 provided with the vacuum port 12 can be vacuumed by the vacuum device. The sterilization medium flow port 13 can be connected to an external sterilization medium supply device (not shown in the figure) so that the sterilization medium supply device can provide sterilization medium to the cabin 11 of the cabin 10 provided with the sterilization medium flow port 13. The vacuum device can be a vacuum pump, and the sterilization medium supply device can be a hydrogen peroxide vaporizer. Correspondingly, the sterilization medium can be hydrogen peroxide vapor.
[0041] Combine Figure 3 As shown, both pods 10 are provided with first inlets and outlets 14 communicating with their respective chambers 11. A connecting pipe assembly 20 may include a connecting pipe 21, with both ends of the connecting pipe 21 communicating with the first inlets and outlets 14 on the two pods 10, respectively. This allows the chambers 11 within the two pods 10 to communicate with each other via the connecting pipe 21.
[0042] The connecting pipe assembly 20 may further include a control valve 22 provided on the connecting pipe 21. The control valve 22 is used to control the connection and disconnection of the connecting pipe 21, thereby enabling the chambers 11 of the two pods 10 to switch between a conducting state and a disconnected state.
[0043] Combine Figure 3 、 Figure 5 and Figure 6 As shown in the figure, the sterilizer also includes a storage box 30 that can be placed in the cabin 11 of the cabin body 10, and the interior of the storage box 30 defines a storage cavity 31 with a second inlet and outlet 32. The storage cavity 31 is suitable for accommodating the aforementioned luminal medical device 100. At the same time, the storage box 30 is also provided with an instrument connector 33 suitable for docking with the first inlet and outlet 14 on each cabin body 10, and the instrument connector 33 can have a docking port adapted to the inlet 101 on the luminal medical device 100. Furthermore, the docking port on the instrument connector 33 can correspond one-to-one with the inlet 101 on the luminal medical device 100, so that it can be used as shown in the figure. Figure 6 The manner shown allows an inlet 101 on the luminal medical device 100 to be connected to a docking port on the device connector 33 .
[0044] Based on the above configuration, when faced with a large number of medical devices to be sterilized, and these medical devices include luminal medical devices 100, the sterilizer disclosed in this embodiment can be used in the manner described below, but is not limited to the following.
[0045] Specifically, after the relevant disinfection and sterilization preparations are completed, a certain number of conventional medical devices (i.e., non-luminal medical devices) can be placed in the chamber 11 of one of the chambers 10 having the vacuum port 12 and the sterilization medium flow port 13, and the luminal medical devices 100 can be placed in the storage chamber 31 of the storage box 30. The inlet ports 101 of the luminal medical devices 100 in the storage box 30 can be connected to the docking ports on the device connector 33 through pipelines. Subsequently, the storage box 30 can be placed as a whole in the chamber 11 of another chamber 10, and the device connector 33 on the storage box 30 can be connected to the device connector 33 as shown in the following figure. Figure 4 The manner shown is connected to the first inlet and outlet 14 on the cabin body 10. Of course, if space permits, some conventional medical instruments can also be placed in the cabin 11 of the cabin body 10 where the storage box 30 is placed.
[0046] After the above work is completed, the chambers 11 of the two chambers 10 are kept sealed, and the control valve 22 on the connecting pipe 21 is opened. On this basis, the chamber 11 of the chamber 10 containing the conventional medical device is evacuated using an external vacuum device. It can be understood that since the chamber 11 of the chamber 10 is connected to the chamber 11 of the other chamber 10 via the connecting pipe 21, the first inlet and outlet 14 of the other chamber 10, the device connector 33 on the storage box 30, the internal flow path of the luminal medical device 100, the storage cavity 31, and the second inlet and outlet 32 on the storage box 30, when the chamber 11 of the chamber 10 containing the conventional medical device is evacuated, the storage cavity 31 of the storage box 30 and the chamber 11 of the other chamber 10 can also be evacuated at the same time.
[0047] After the vacuum levels in the chambers 11 of the two cabins 10 and the storage chamber 31 meet the requirements for disinfection and sterilization, the disinfection and sterilization operation can be started. Specifically, an external sterilization medium supply device can be used to provide sterilization medium to the chamber 11 of the cabin 10 where conventional medical devices are placed, so that the medical devices in the chamber 11 of the cabin 10 can be disinfected and sterilized by the sterilization medium. At the same time, since sterilization media such as hydrogen peroxide vapor have good fluidity, the sterilization medium entering the chamber 11 of the cabin 10 where conventional medical devices are placed can flow through the connecting tube 21 and the device connector 33 on the storage box 30 in sequence and then enter the internal flow path of the luminal medical device 100 to disinfect and sterilize the internal flow path of the luminal medical device 100. Afterwards, the sterilizing medium flowing through the internal flow path of the luminal medical device 100 will flow out of the outflow port 102 of the luminal medical device 100 and into the storage cavity 31 of the storage box 30, thereby disinfecting and sterilizing the surface of the luminal medical device 100. Finally, the sterilizing medium in the storage cavity 31 can flow through the second inlet and outlet 32 of the storage box 30 into the compartment 11 of the housing 10 containing the storage box 30, thereby disinfecting and sterilizing other conventional medical devices placed in the compartment 11.
[0048] As can be seen, the sterilizer disclosed in this embodiment, by providing two independent chambers 10 and a connecting pipe assembly 20 for connecting the chambers 11 of the two chambers 10, can sterilize more medical devices in a single pass, thereby improving disinfection and sterilization efficiency. Furthermore, the provision of a storage box 30 can also achieve sufficient disinfection and sterilization of the internal flow paths and surfaces of lumen-type medical devices 100, effectively expanding the sterilizer's scope of application.
[0049] It is understandable that in some embodiments of the present invention, such as Figure 2 As shown, both chambers 10 can be provided with a vacuum port 12 and a sterilization medium flow port 13 that communicate with their respective chambers 11. Thus, when it is necessary to disinfect and sterilize luminal medical devices 100, the storage box 30 containing the luminal medical devices 100 can be placed in the chamber 11 of either chamber 10, and the sterilizer can be used in a manner substantially consistent with that described above to disinfect and sterilize a certain number of conventional medical devices and luminal medical devices 100 at a time. Furthermore, when the control valve 22 on the connecting pipe 21 is closed, the two chambers 10 can function as independent disinfection and sterilization chambers without interfering with each other.
[0050] Combine Figure 5 and Figure 6As shown, the storage box 30 may include a box body 34 and a box cover 35. The interior of the box body 34 serves as a storage cavity 31, and a storage port communicating with the storage cavity 31 may be provided, such as on the top of the box body 34, to facilitate placement or removal of the luminal medical device 100 into or from the storage cavity 31. The box cover 35 is used to open or close the storage port on the box body 34. For example, the box cover 35 may be a component that is detachably connected to the box body 34.
[0051] The second inlet and outlet 32 can be provided on the lid 35 of the storage box 30. There can be multiple second inlets and outlets 32 provided on the storage box 30 to maximize the flow of fluid into and out of the storage cavity 31. For example, the drawings of this embodiment illustrate a configuration in which five second inlets and outlets 32 are provided.
[0052] In addition, a filter 36 can be provided at each second inlet and outlet 32 so as to prevent pollutants such as dust in the external environment from entering the storage cavity 31 and contaminating the luminal medical device 100 when the storage box 30 is in the external environment.
[0053] The filter element 36 can be made of breathable steel, which has excellent filtering and ventilation properties. It is understood that using breathable steel as the filter element 36 not only allows the sterilizing medium entering the storage cavity 31 to flow from the second inlet and outlet 32 into the compartment 11 of the housing 10 containing the storage box 30, but also effectively blocks contaminants such as bacteria from the outside air from entering the storage cavity 31 after the storage box 30 is removed from the corresponding compartment 11, thereby further reducing the risk of contamination of the luminal medical device 100 within the storage cavity 31.
[0054] Combine Figure 2 and Figure 3 As shown, each cabin 10 is further provided with a hatch 15 communicating with its own cabin 11 , so that medical equipment in the corresponding cabin 11 can be taken in and out through the hatch 15 .
[0055] On this basis, the sterilizer disclosed in this embodiment may further include a door assembly 40 , wherein the door assembly 40 is used to open or close the hatches 15 on the two cabin bodies 10 .
[0056] Specifically, refer to Figure 3 or Figure 7 As shown, the hatch assembly 40 may include a guide mechanism 41 and two hatches 42. The two hatches 42 correspond one to one with the two cabins 10. Both hatches 42 are disposed on the guide mechanism 41 and are configured to move toward or in opposite directions along the arrangement direction of the two cabins 10 to close or open the hatch openings 15 on the corresponding cabins 10, respectively.
[0057] The guide mechanism 41 may be a movable track located on either side of the hatch opening 15 of the two cabins 10 and extending along the arrangement direction of the two cabins 10. The two hatches 42 may be slidably engaged with the movable track via a movable component such as a pulley, and the movement of the two hatches 42 may be driven by an additional linear drive device (not shown), such as a linear motor, a pneumatic cylinder, etc.
[0058] It can be understood that by adopting the above-mentioned structure of the door assembly 40, since the two doors 42 are arranged together on a guide mechanism 41, it helps to optimize the structural design of the door assembly 40 and enables both cabins 10 to be used independently as disinfection and sterilization cabins.
[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
