Description

Technical Field

[0001] The present invention relates to the field of medical devices, in particular to a sterilization device for sterilizing flexible endoscopes using hydrogen peroxide, and more particularly to a hydrogen peroxide low-temperature plasma flexible endoscope sterilizer. Background Art

[0002] In the medical field, disinfection and sterilization of medical devices is particularly important. Today, the most advantageous and popular method for disinfection and sterilization of medical devices is hydrogen peroxide disinfection and sterilization. In order to improve the sterilization effect, shorten the sterilization time, and reduce the sterilization cost, it is usually necessary to use heating or ionization to vaporize or plasma the hydrogen peroxide liquid before disinfecting and sterilizing the medical devices. At present, hydrogen peroxide vaporization or plasma disinfection and sterilization equipment has become the preferred device for disinfection and sterilization of medical devices.

[0003] Flexible endoscopes, also known as flexible endoscopes, are medical devices that primarily perform examinations, diagnoses, and treatments through the body's natural cavities. Gastroscopes, colonoscopes, laryngoscopes, and bronchoscopes, for example, primarily enter the body through the digestive, respiratory, and urinary tracts. Because they must enter the human body and come into direct contact with tissues and organs, disinfection and sterilization of flexible endoscopes are particularly important. The "Technical Specification for Cleaning and Disinfection of Flexible Endoscopes" WS507-2016 requires that "all flexible endoscopes should be thoroughly cleaned and subjected to high-level disinfection or sterilization after each use. Flexible endoscopes and accessories that enter sterile human tissues or organs, or come into contact with damaged skin or mucous membranes, should be sterilized. Flexible endoscopes and accessories that come into contact with intact mucous membranes, but not sterile human tissues or organs, or damaged skin or mucous membranes, should undergo high-level disinfection."

[0004] Existing hydrogen peroxide plasma sterilizers for flexible endoscopes generally place the endoscope directly in a sterilization chamber, evacuate the sterilization chamber, and then fill the sterilization chamber with hydrogen peroxide gas, so that the hydrogen peroxide gas enters the interior of the endoscope lumen for sterilization and disinfection. The lumen length and diameter of flexible endoscopes vary, and some of the lumens of flexible endoscopes are open at both ends, which requires sterilization, while others are open at one end and closed at the other, which does not require sterilization. When sterilizing a slender lumen using the above method, due to the long length of the lumen, hydrogen peroxide cannot completely fill the entire lumen, or the concentration of hydrogen peroxide in the lumen is low, resulting in poor sterilization effect; and for the lumen that does not require sterilization, hydrogen peroxide gas also enters its interior. Since it is only open at one end, the hydrogen peroxide gas in the lumen is difficult to completely remove, thereby reducing the service life of the endoscope and even causing damage to the endoscope. Summary of the Invention

[0005] In response to the above-mentioned deficiencies in the prior art, the present invention provides a hydrogen peroxide low-temperature plasma flexible endoscope sterilizer, comprising a main body, on which a sterilization chamber, a purification device, a liquid adding device and a vacuum device are provided, the purification device, the liquid adding device and the vacuum device are all connected to the sterilization chamber, a storage rack and an electrode net are provided in the sterilization chamber, and a first connecting member and a second connecting member are also provided in the sterilization chamber; one end of the first connecting member passes through the side wall of the sterilization chamber and is connected to the output end of the purification device, and the other end of the first connecting member is connected to the opening of the tube cavity to be sterilized of the endoscope; one end of the second connecting member passes through the side wall of the sterilization chamber and is provided with a gas supply component, the gas supply component can open and close the second connecting member and can input clean gas into the second connecting member, the other end of the second connecting member passes through the side wall of the sterilization chamber and is connected to the vacuum device, and a first connector connected to the opening of the tube cavity that does not need to be sterilized of the endoscope is provided on the peripheral wall of the second connecting member. The hydrogen peroxide gas is introduced from the purification device into the lumen of the endoscope that needs to be sterilized through the first connector, and then enters the sterilization chamber through the other port of the lumen that needs to be sterilized. This ensures that the lumen that needs to be sterilized is filled with hydrogen peroxide gas and that the concentration of hydrogen peroxide inside the lumen needs to be sterilized is appropriate, thereby ensuring the sterilization effect of the endoscope. The second connector is connected to the opening of the lumen that does not need to be sterilized, so that the hydrogen peroxide gas cannot enter the lumen that does not need to be sterilized, thereby avoiding damage to the lumen that does not need to be sterilized during sterilization and reducing the service life of the endoscope.

[0037] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0038] The following combination Figures 1 to 7 The present invention is described in detail.

[0039] Please refer to Figure 1 As shown, a hydrogen peroxide low-temperature plasma flexible endoscope sterilizer includes a main body 100, on which a sterilization chamber 101, a purification device 103, a liquid adding device 105 and a vacuum device 107 are provided, wherein the purification device 103, the liquid adding device 105 and the vacuum device 107 are all connected to the sterilization chamber 101, and a storage rack 108 and an electrode mesh 109 are provided in the sterilization chamber 101.

[0040] The two ends of a flexible endoscope are the lumen that needs to be sterilized and the lumen that does not need to be sterilized. The lumen that needs to be sterilized is the part that extends into the human organs for inspection or sampling, and must be thoroughly sterilized to ensure its safe use; the lumen that does not need to be sterilized is the external end that does not enter the human body, and usually contains corresponding electronic components. Long-term contact with corrosive hydrogen peroxide gas should be avoided as much as possible.

[0041] The sterilization chamber 101 is also equipped with a first connector 110 and a second connector 130. One end of the first connector 110 extends through the side wall of the sterilization chamber 101 and connects to the output of the purification device 103. The other end of the first connector 110 connects to the opening of the endoscope's lumen that needs to be sterilized. One end of the second connector 130 extends through the side wall of the sterilization chamber 101 and is equipped with a gas supply assembly 150. The gas supply assembly 150 can open and close the second connector 130 and supply clean gas into the second connector 130. The other end of the second connector 130 extends through the side wall of the sterilization chamber 101 and connects to the vacuum device 107. A first connector is provided on the peripheral wall of the second connector 130 to connect to the opening of the endoscope's lumen that does not need to be sterilized. After the endoscope is connected to the first and second connectors 110 and 130, the door of the sterilization chamber 101 is closed, creating a sealed environment within the sterilization chamber 101. Then, the air in the sterilization chamber 101 and the endoscope lumen that does not require sterilization is extracted synchronously through the vacuum device 107, so that the interior of both is in a vacuum state. After the vacuuming work is completed, the purification device 103 and the gas supply assembly 150 are opened at the same time. The hydrogen peroxide gas in the purification device 103 enters the sterilization chamber 101 through the first connector 110 and the endoscope lumen that needs to be sterilized in turn, so that the hydrogen peroxide gas can spread throughout every part of the lumen that needs to be sterilized, ensuring the effect of disinfecting and sterilizing the inner and outer walls of the lumen that needs to be sterilized; the outside air is filtered by the gas supply assembly 150 and enters the lumen that does not require sterilization through the second connector 130, so that the air pressure in the lumen that does not require sterilization is consistent with that in other parts of the sterilization chamber 101, avoiding rupture of the wall of the lumen that does not require sterilization. In addition, the endoscope lumen that does not require sterilization is connected to the second connector 130, so that the hydrogen peroxide gas in the sterilization chamber 101 cannot enter the lumen that does not require sterilization of the endoscope, avoiding residual hydrogen peroxide gas inside it.

[0042] For details, please refer to Figure 2As shown, the first connecting member 110 includes a first air pipe 111, one end of which is provided with a first mounting head 113, and an inner wall of the sterilization chamber 101 is provided with a first mounting seat 115, the first mounting seat 115 is sealed with the sterilization chamber 101, and the first mounting head 113 can extend into the first mounting seat 115 and is sealed with the first mounting seat 115. The first mounting head 113 and the first mounting seat 115 are magnetically connected, or can be threaded or slotted. In this embodiment, the first air pipe 111 is H-shaped, that is, the first air pipe 111 is divided into a main air pipe and a branch air pipe, and the number of the branch air pipes is determined according to the number of lumens that need to be sterilized in the endoscope. In other embodiments, the first air pipe 111 may also have only the main air pipe, and the surrounding wall of the main air pipe is provided with connection ports equal to the number of lumens that need to be sterilized in the endoscope. Preferably, the first air supply pipe 111 can also connect the lower end of the main air supply pipe to the peripheral wall of the branch air supply pipe, and a plurality of connection ports are spaced apart on the peripheral wall of the branch air supply pipe for connecting the lumen of the endoscope that needs to be sterilized.

[0043] Please refer to Figure 1 、 Figure 3 and Figure 7 As shown, the second connecting member 130 includes a second air supply pipe, and both ends of the second air supply pipe are provided with a fixing assembly 170. The fixing assembly 170 passes through the bulkhead of the sterilization chamber 101 and is sealed with the bulkhead. The fixing assembly 170 includes a second mounting seat 171, a third mounting seat 173, and a second mounting head 175. The upper end of the third mounting seat 173 passes through the bulkhead of the sterilization chamber 101 and extends into the second mounting seat 171. The second mounting seat 171, the bulkhead and the third mounting seat 173 are fixed in sequence by bolts. A groove 177 is provided on the table where the second mounting seat 171 and the third mounting seat 173 abut against the bulkhead, and a third sealing ring 179 is provided in the groove 177. When the second mounting seat 171, the bulkhead and the third mounting seat 173 are fixed by bolts, the third sealing ring 179 can be squeezed to seal the three, thereby preventing hydrogen peroxide gas from leaking out during the sterilization process. Figure 3 The connection relationship between the fixing assembly 170 provided at the lower end of the second connecting member 130 and the sterilization chamber 101 is shown in FIG. 1 , and the connection relationship between the fixing assembly 170 provided at the upper end of the second connecting member 130 and the sterilization chamber 101 is shown in FIG. Figure 3 The lower end of the gas delivery assembly 150 located outside the sterilization chamber 101 is directly and sealedly connected to the upper end of the fixing assembly 170 provided at the upper end of the second connecting member 130 .

[0044] The lower end of the second mounting head 175 can extend into the second mounting seat 171 and the third mounting seat 173 and be sealed with the second mounting seat 171 and / or the third mounting seat 173. The second mounting head 175 and the second mounting seat 171 are connected by magnetic attraction, threaded connection or slot connection.

[0045] Specifically, the lower end of the second connecting member 130 is connected to the vacuum device 107 via a fixing assembly 170 provided at the lower end.

[0046] Specifically, the upper end of the second connecting member 130 is connected to the gas delivery component 150 through a fixing component 170 provided at the end.

[0047] Please refer to Figure 4 As shown, the air delivery assembly 150 includes a filter 151 and a solenoid valve 153. The filter 151 is sealedly connected to the fixed assembly 170 via the solenoid valve 153. When the solenoid valve 153 is closed, outside air cannot pass through the filter 151 and enter the second connecting member 130. When the solenoid valve 153 is opened, outside air, under the negative pressure of the sterilization chamber 101, passes through the filter 151 and enters the second connecting member 130 and then enters the non-sterilized lumen of the endoscope. The filter 151 can filter and sterilize the air, and the incoming air will not contaminate the second connecting member 130 and the non-sterilized lumen of the endoscope. The filter 151 is an existing air filter, and its specific structure will not be described in detail.

[0048] Please refer to Figure 1 and Figure 5 As shown, a sterilization box 190 is also provided in the sterilization chamber 101. The sterilization box 190 includes a box body 191. The sterilization box 190 is used to place the endoscope. A silicone bracket adapted for the endoscope is provided in the sterilization box 190, and the silicone bracket is used to fix the endoscope. During sterilization, the sterilization box 190 is placed on the storage rack 108. At least one second connector 195 and a third connector 197 are provided on the side wall of the box body 191. One end of the second connector 195 can be connected to the first connector 110, and the other end of the second connector 195 is connected to one end of the lumen of the endoscope that needs to be sterilized. One end of the third connector 197 is connected to the first connector, and the other end of the third connector 197 is connected to the open end of the lumen of the endoscope that does not need to be sterilized, thereby facilitating the placement and sterilization of the endoscope. In this embodiment, a plurality of spare connectors are also provided on the side wall of the box body 191, and their structure is the same as that of the second connector 195 and the third connector 197. When the second connector 195 and the third connector 197 are damaged or there are too many connectable openings for the endoscope, the spare connectors can be used.

[0049] Please refer to Figure 5 and Figure 6As shown, the second connector 195 and the third connector 197 are both provided with a plug 196 at one end outside the box body 191. The plug 196 is T-shaped and is connected to the peripheral wall of the second connector 195 or the third connector 197 through a soft rubber connecting belt. Under normal circumstances, the plug 196 is inserted into the second connector 195 or the third connector 197, thereby sealing the second connector 195 and the third connector 197. During sterilization, it is necessary to use a second connector 195 and a third connector 197 and pull the plug 196 out of the second connector 195 and the third connector 197.

[0050] Furthermore, the sterilization box 190 further includes a box cover 193. The inner wall of the box cover 193 is provided with a second sealing ring. When the box cover 193 is buckled onto the box body 191, the side walls of the box cover 193 and the side walls of the box body 191 can jointly squeeze the second sealing ring, thereby sealing the gap between the box cover 193 and the box body 191.

[0051] Furthermore, at least one lock catch is provided on opposing side walls of the lid 193, and a lock seat is provided on the box body 191 that matches the lock catch. The lock catch and lock seat cooperate to secure the lid 193 to the box body 191. The combination of the lock catch and lock seat is a conventional lock and will not be described in detail here. In this embodiment, two lock catches are spaced apart on opposing side walls of the lid 193, allowing the lid 193 to more tightly fit the box body 191.

[0052] Preferably, at least one ventilation window 199 is provided on the sidewall of the box body 191. A first sealing ring 201 is provided on the peripheral wall of the ventilation window 199. The first sealing ring 201 has a U-shaped cross-section. When installed on the ventilation window 199, the first sealing ring 201 partially wraps around the peripheral wall of the ventilation window 199. Limiting bars 203 are interspersed on the sidewall of the box body 191, with a gap between the limiting bars 203 and the sidewall of the box body 191. A fixing plate 194 is provided between the limiting bars 203 and the sidewall of the box body 191. The fixing plate 194 can be withdrawn from the gap between the limiting bars 203 and the sidewall of the box body 191. When the fixing plate 194 is inserted into the gap, the sidewall of the fixing plate 194 can abut against the first sealing ring 201, thereby forming a seal between the fixing plate 194 and the sidewall of the box body 191 via the first sealing ring 201. In this embodiment, an opening is provided between the upper end of the limiting strip 203 and the box body 191 to facilitate the insertion of the fixing plate 194 into the gap from the vertical direction. The fixing plate 194 is provided with an opening that is adapted to the size of the air window 199. When the fixing plate 194 is installed in place, the air window 199 can overlap with the opening. The opening is covered with a bacteria-isolating material 205, and the bacteria-isolating material 205 is bonded to the side wall of the fixing plate 194. The bacteria-isolating material 205 is a disposable consumable, such as Tyvek, which is breathable and can form a biological barrier to isolate bacteria. During the sterilization process, both hydrogen peroxide gas and air can flow from the sterilization box 190 into the sterilization chamber 101 through the bacteria-isolating material 205, and then be extracted through the vacuum device 107. After the endoscope is sterilized in the sterilization equipment, it needs to be stored aseptically. If the endoscope is directly taken out of the sterilization chamber 101 and transferred to a storage device, the endoscope will be exposed to the air during the transfer process, which will cause secondary contamination. Therefore, in this application, the sterilization box 190 is used as the storage device for the endoscope to avoid secondary contamination of the endoscope.

[0053] The working principle of a hydrogen peroxide low-temperature plasma flexible endoscope sterilizer is:

[0054] During use, the endoscope is placed on the silicone holder inside the sterilization box 190. The opening of the lumen to be sterilized is connected to the end of the second connector 195 located inside the sterilization box 190. The opening of the lumen not to be sterilized is connected to the end of the third connector 197 located inside the sterilization box 190. New antibacterial material 205 is replaced, and the box cover 193 is installed. The box cover 193 is fixed to the box body 191 using the lock buckle and lock seat. Finally, the sterilization box 190 is placed on the storage rack 108.

[0055] Then pull out the plugs 196 on the second connector 195 and the third connector 197 that need to be used, connect the first connector 110 to the outer end of the second connector 195, and connect the first connector to the outer end of the third connector 197. Finally, close the sterilization chamber 101, start the sterilization program, and the endoscope can be sterilized.

[0056] After sterilization is completed, the first connector 110 is separated from the outer end of the second connector 195, the outer end of the first connector is separated from the outer end of the third connector 197, and then the plugs 196 on the corresponding second connector 195 and third connector 197 are reset.

[0057] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
