DETAILED DESCRIPTION

[0035] 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 in conjunction with specific implementation methods below. 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.

[0036] Compared to the embodiments shown in the drawings, feasible embodiments within the scope 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.

[0037] Example 1

[0038] Embodiment 1 of the present invention discloses a hydrogen peroxide plasma sterilization device (for the sake of convenience, hereinafter referred to as "sterilization device"), 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 luminal medical device 100.

[0039] 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. As for this type of tubular cavity 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 for external fluid to enter the internal flow path, and the outlet 102 is used for the fluid flowing through the internal flow path to flow out. The specific structure of this type of tubular cavity medical device 100 can refer to the structure of the tubular cavity medical device 100 known in the prior art, and will not be elaborated in detail here.

[0040] like Figure 2 As shown in FIG. 1 , it shows the general structure of the exemplary sterilization device disclosed in this embodiment. Figure 2 In the sterilization device shown, the sterilization device may include two cabins 10 and a connecting pipe assembly 20 .

[0041] Combination Figure 2 and Figure 3As shown in the figure, the interior of each cabin 10 defines a cabin 11 suitable for accommodating medical devices and sterilizing the medical devices. It can be understood that the single cabin 10 described in this embodiment can have a structure that is basically the same as the cabin 10 of the hydrogen peroxide plasma sterilization device known in the prior art, and the two cabins 10 constituting the sterilization device disclosed in this embodiment can also have a basically consistent structure.

[0042] Furthermore, the two cabins 10 can be arranged side by side in one direction to optimize the structural design of the sterilization equipment as much as possible. For example, the drawings of this embodiment show that the two cabins 10 are arranged in a vertically overlapping manner. Of course, in other embodiments of the present invention, the arrangement of the two cabins 10 is not limited to this and is not limited here.

[0043] like Figure 2 As shown, at least one cabin 10 is provided with a vacuum port 12 and a sterilization medium flow port 13 which are connected to 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, and 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 the cabin 11 of the cabin 10 provided with the sterilization medium flow port 13 with a sterilization medium. The vacuum device can be a vacuum pump, and the sterilization medium supply device can be a hydrogen peroxide evaporator, and correspondingly, the sterilization medium can be hydrogen peroxide vapor.

[0044] Combination Figure 3 As shown, both cabins 10 are provided with a first inlet and outlet 14 connected to their own cabins 11. The connecting pipe assembly 20 may include a connecting pipe 21, and both ends of the connecting pipe 21 are respectively connected to the first inlet and outlet 14 on the two cabins 10. In this way, the cabins 11 inside the two cabins 10 can be connected by means of the connecting pipe 21.

[0045] The connecting pipe assembly 20 may further include a control valve 22 disposed 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 cabins 10 to switch between a conducting state and a disconnected state.

[0046] Combination Figure 3 , Figure 5 and Figure 6As shown in the figure, the sterilization equipment 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. Among them, 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 method shown allows an inlet 101 on the tubular cavity medical device 100 to be connected to a docking port on the device connector 33 .

[0047] 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 sterilization device disclosed in this embodiment can be used in the manner described below but is not limited to the following.

[0048] Specifically, after the relevant disinfection and sterilization preparations are completed, a certain number of conventional medical devices (i.e., non-lumen medical devices) can be placed in the chamber 11 of one of the cabins 10 having the vacuum port 12 and the sterilization medium flow port 13, and the lumen medical devices 100 can be placed in the storage chamber 31 of the storage box 30, and the inlet ports 101 of the lumen 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 is placed as a whole in the chamber 11 of another cabin 10, and the device connector 33 on the storage box 30 is connected as shown in the 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 additional conventional medical devices can also be placed in the cabin 11 of the cabin body 10 where the storage box 30 is placed.

[0049] After the above work is completed, the chambers 11 of the two chambers 10 are kept in a sealed state, and the control valve 22 on the connecting pipe 21 is opened. On this basis, the chamber 11 of the chamber 10 with the conventional medical device placed therein is vacuumed by using an external vacuum device. It can be understood that the chamber 11 of the chamber 10 is connected with the chamber 11 of the other chamber 10 through the connecting pipe 21, the first inlet and outlet 14 of the other chamber 10, the instrument connector 33 on the storage box 30, the internal flow path of the tubular cavity medical device 100, the storage cavity 31 and the second inlet and outlet 32 ​​on the storage box 30. Therefore, when the chamber 11 of the chamber 10 with the conventional medical device placed therein is vacuumed, the storage cavity 31 of the storage box 30 and the chamber 11 of the other chamber 10 can also be vacuumed.

[0050] After the vacuum degree in the chambers 11 of the two cabins 10 and the storage chamber 31 meets the requirements of disinfection and sterilization, the disinfection and sterilization operation can be started. Specifically, an external sterilization medium supply device can be used to provide a 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, based on the good fluidity of sterilization media such as hydrogen peroxide vapor, the sterilization medium entering the chamber 11 of the cabin 10 where conventional medical devices are placed can flow through the connecting pipe 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 sterilization medium flowing through the internal flow path of the luminal medical device 100 will flow out from the outlet 102 of the luminal medical device 100 and enter the storage cavity 31 of the storage box 30, thereby sterilizing the surface of the luminal medical device 100. Finally, the sterilization medium in the storage cavity 31 can flow from the second inlet 32 ​​of the storage box 30 into the chamber 11 of the cabin body 10 in which the storage box 30 is placed, so as to sterilize other conventional medical devices placed in the chamber 11.

[0051] It can be seen that the sterilization device disclosed in this embodiment, by providing two independent cabins 10 and a connecting pipe assembly 20 for connecting the cabins 11 of the two cabins 10, can sterilize more medical devices at a time to improve the sterilization efficiency. At the same time, through the provision of the storage box 30, the internal flow path and the surface of the tubular cavity medical device 100 can also be fully sterilized, effectively expanding the scope of application of the sterilization device.

[0052] It is understood that in some embodiments of the present invention, Figure 2 As shown, both cabins 10 can be provided with a vacuum port 12 and a sterilization medium flow port 13 that are connected to their own cabins 11. In this way, when it is necessary to disinfect and sterilize the luminal medical device 100, the storage box 30 containing the luminal medical device 100 can be placed in the cabin 11 of any cabin 10, and the sterilization equipment can be used in a manner basically consistent with the above, so that a certain number of conventional medical devices and luminal medical devices 100 can be disinfected and sterilized at a time. At the same time, when the control valve 22 on the connecting pipe 21 is closed, the two cabins 10 can be used as independent disinfection and sterilization cabins without interfering with each other.

[0053] Combination 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 on the top of the box body 34, such as to facilitate placing the luminal medical device 100 into the storage cavity 31 or taking it out of the storage cavity 31 through the storage port. 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 detachably connected to the box body 34.

[0054] The second inlet and outlet 32 ​​may be provided on the cover 35 of the storage box 30. At the same time, there may be multiple second inlets and outlets 32 provided on the storage box 30 to maximize the flow of fluid in and out of the storage cavity 31. For example, the drawings of this embodiment show a situation where five second inlets and outlets 32 are provided.

[0055] Furthermore, a filter 36 may 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.

[0056] The filter element 36 may be a breathable steel having a good filtering and ventilation effect. It is understandable that by using the breathable steel as the filter element 36, not only can the sterilization medium entering the storage cavity 31 flow from the second inlet and outlet 32 ​​into the compartment 11 of the cabin body 10 where the storage box 30 is placed, but also when the storage box 30 is taken out of the corresponding compartment 11, the presence of the breathable steel can effectively prevent bacteria and other pollutants in the external air from entering the storage cavity 31, so as to further reduce the risk of contamination of the luminal medical device 100 in the storage cavity 31.

[0057] Combination Figure 2 and Figure 3 As shown, each cabin 10 is also provided with a hatch entrance 15 connected to its own cabin 11 , so that medical equipment in the corresponding cabin 11 can be taken in and out through the hatch entrance 15 .

[0058] On this basis, the sterilization device disclosed in this embodiment may further include a door assembly 40 . The door assembly 40 is used to open or close the hatch openings 15 on the two cabin bodies 10 .

[0059] 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 to the two cabins 10 one by one, and the two hatches 42 are both arranged on the guide mechanism 41, and the two hatches 42 are configured to be able to move in opposite directions along the arrangement direction of the two cabins 10 to close or open the hatch opening 15 on the corresponding cabin 10 respectively.

[0060] The guide mechanism 41 may be a movable track located on both sides of the hatch openings 15 of the two cabins 10 and extending along the arrangement direction of the two cabins 10. The two hatches 42 may be slidably matched with the movable track through movable parts such as pulleys, and the movement of the two hatches 42 may be driven by an additional linear drive device (not shown in the figure), such as a linear motor, a cylinder, etc.

[0061] It can be understood that by adopting the above-structured 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 the two cabins 10 to be used independently as disinfection and sterilization cabins.

[0062] Example 2

[0063] Based on Example 1, this embodiment discloses another hydrogen peroxide plasma sterilization device, which is different from the hydrogen peroxide plasma sterilization device disclosed in Example 1 in that the hydrogen peroxide plasma sterilization device disclosed in this embodiment may further include a heating component (not shown in the figure) disposed on each cabin 10, wherein the heating component is configured to heat the cabin 11 of the cabin 10. For example, the heating component may be an electric heater disposed on the outer wall of each cabin 10.

[0064] It is understandable that by providing a heating component on each cabin 10, it is helpful to heat the cabin 11 of each cabin 10 as needed, thereby achieving the temperature in the cabin 11 of each cabin 10 being controlled within a temperature range preferably suitable for disinfecting and sterilizing medical devices.

[0065] Furthermore, the hydrogen peroxide plasma sterilization equipment disclosed in this embodiment may also include a detection component and a controller.

[0066] In this embodiment, the detection component is configured to detect the temperature and / or sterilization medium concentration (i.e., hydrogen peroxide concentration) in the cabin 11 of each cabin 10. The detection component may include a temperature detection sensor and a sterilization medium concentration detection sensor. A temperature detection sensor (not shown in the figure) may be provided on each cabin 10 to detect the temperature in the cabin 11 of the cabin 10 through the temperature detection sensor. Secondly, a sterilization medium concentration detection sensor (not shown in the figure) may be provided on each cabin 10 to detect the sterilization medium concentration in the cabin 11 of the cabin 10 through the sterilization medium concentration detection sensor.

[0067] In this embodiment, the heating component, the detection component, and the sterilization medium supply device described in the above embodiment 1 are all communicatively connected to the controller. The controller is adapted to receive the temperature information and / or the sterilization medium concentration information in the cabin 11 of each cabin 10 detected by the detection component, so that the controller can control the temperature and / or the sterilization medium concentration in the cabin 11 of each cabin 10 according to the received temperature information and / or the sterilization medium concentration information.

[0068] For example, when the controller determines that the temperature in the cabin 11 of the cabin 10 is low according to the received temperature information, the controller can control the corresponding heating component on the cabin 10 to operate so as to increase the temperature in the cabin 11 of the cabin 10 to the target temperature. Correspondingly, when the controller determines that the sterilization medium concentration in the cabin 11 of the cabin 10 is low according to the received sterilization medium concentration information, the controller can control the sterilization medium supply device to replenish the sterilization medium in the cabin 11 of the cabin 10 to achieve the target sterilization medium concentration.

[0069] It can be understood that by adding a detection component for detecting the temperature and / or the concentration of the sterilization medium in the cabin 11 of each cabin 10, and a controller suitable for controlling the temperature and / or the concentration of the sterilization medium in the cabin 11, a closed-loop control system can be formed, which is beneficial for controlling the temperature and / or the concentration of the sterilization medium in the cabin 11 of each cabin 10 within a preferred range, and further helps to improve the quality of disinfection and sterilization of medical devices.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
