Description

Technical Field

[0001] This utility model relates to the field of medical device cleaning technology, specifically to a device for cleaning the inner core of an oxygen humidification bottle. Background Technology

[0002] my country's Ministry of Health has promulgated and implemented mandatory health industry standards, stipulating that a centralized management approach be adopted for the collection, cleaning, disinfection, packaging, and supply of all items requiring disinfection and reuse. Oxygen humidification cylinders and their inner cores are one such item. Figure 5 The image shows the inner core of an oxygen humidification bottle. The bottom of the inner core extends into distilled water, and the top connects to the oxygen tubing and the oxygen cylinder. Oxygen exits through a hole at the bottom of the inner core, emerging from the water inside the humidification bottle, and is then supplied to the patient's mouth and nose through another tubing, thus achieving oxygen inhalation. Since oxygen therapy is a common clinical treatment, contamination of the inner core of the oxygen humidification bottle can lead to the deposition of large amounts of pathogens in the lower respiratory tract via aerosol inhalation, causing respiratory infections. Therefore, the effectiveness of cleaning and disinfection directly affects the safety of oxygen therapy for patients.

[0003] The WS310.2-2016 health industry standard outlines the technical operating procedures for cleaning, disinfection, and sterilization in hospital disinfection supply centers. It clearly defines the entire process for removing contaminants from medical devices, instruments, and supplies, including rinsing, washing, rinsing, and terminal rinsing. Rinsing involves using running water to remove contaminants from the surface of instruments, instruments, and supplies, while washing uses cleaning water containing chemical cleaning agents to remove contaminants. However, these procedures are suitable for large-scale centralized medical device cleaning and disinfection operations in hospitals and other institutions. For specific thin-tube instruments and instruments, such as the inner surface of the inner core of oxygen humidification cylinders, cleaning is often ineffective, and disposable cleaning leads to waste and increased costs. Currently, there is no dedicated cleaning device for the inner core of oxygen humidification cylinders, forcing most inner cores to be placed horizontally in cleaning equipment. Traditional cleaning equipment can only rinse the surface with water, while the inner core cavity, being too narrow, cannot receive direct water rinsing. Even when water enters the cavity, it remains stagnant, making it difficult to drain the water and achieving thorough cleaning, disinfection, and drying. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a cleaning device for the inner core of oxygen humidification bottles. This solves the problem that existing oxygen humidification bottle inner cores cannot effectively clean and dry the interior, leading to incomplete cleaning and potential respiratory infections in patients. This cleaning device, as a specialized piece of equipment, is capable of thoroughly cleaning and disinfecting the inner core of oxygen humidification bottles both internally and externally, and can be used for batch processing, improving both cleaning efficiency and quality.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] An oxygen humidification bottle inner core cleaning device includes an explosion-proof box and an explosion-proof cover installed on the explosion-proof box. A heating box is fixedly installed on the upper part of the explosion-proof box, and a heat preservation area is located below the heating box. A heating resistance wire is installed on the lower surface of the heating box, and an air pump is installed at the bottom of the heat preservation area. Several equidistantly arranged flushing components are arranged through the upper surface of the explosion-proof box. Each flushing component includes a flushing head located on the upper surface of the explosion-proof box. The bottom of the flushing head is connected to a drying pipe, a flushing pipe, and an external branch pipe that extend into the explosion-proof box. The bottom of the external branch pipe is bent and extends into one side of the heating box, and its end is connected to an external main pipe. The external main pipe is connected to the water spray end of an external fully automatic sterilizer. The drying pipe and the flushing pipe are respectively connected to the air pump and the heating box, and a first solenoid valve and a second solenoid valve are respectively installed on the drying pipe and the flushing pipe. A fixing component for connecting and fixing the inner core body is provided on the flushing component.

[0007] Preferably, the drying tube is flush against the inner wall of the explosion-proof box and bypasses the heating box. The bottom end of the drying tube is connected via a connecting pipe, which is connected to the output end of the air pump. In a preferred embodiment, the drying tube, rinsing tube, and flushing components are all made of high-temperature resistant stainless steel. This arrangement prevents the heating resistance wire from overheating and damaging the pipes.

[0008] Preferably, the rinsing head corresponds to the port of the inner core body. This arrangement allows the rinsing head to be aligned with the port of the inner core body, facilitating rinsing of the inner core body.

[0009] Preferably, the top edge of the explosion-proof box is provided with a connecting edge, and a water guide pipe is provided on one side of the connecting edge. A control valve is provided on the water guide pipe. By providing a connecting edge to enclose the top of the explosion-proof box, water used for rinsing the inner core body is prevented from flowing around and can be discharged through the water guide pipe.

[0010] Preferably, the lower surface of the fixing component has several fixing grooves that correspond to and mate with the flushing head. A through groove is formed at the top center of each fixing groove, and fixing holes are formed at the edges of the fixing component. A fixing bolt corresponding to the fixing hole is provided on the top of the explosion-proof box. In a preferred embodiment, the depth of the fixing groove is less than or equal to the sum of the thicknesses of the flushing head and the end of the inner core body. This design allows the end of the inner core body to be fixed to the flushing head via the fixing groove, while the through groove facilitates the passage of the inner core body.

[0011] Preferably, the heating chamber is provided with an inlet pipe and a drain pipe extending from the explosion-proof chamber at its top and bottom, respectively, and the ends of the inlet pipe and the drain pipe are threaded with sealing caps. The inlet pipe facilitates the injection of pure water into the heating chamber, and the drain pipe facilitates the discharge of residual water from the heating chamber.

[0012] Preferably, a one-way air valve communicating with the insulation zone is provided on one side of the explosion-proof enclosure. By providing a one-way air valve, air can enter the explosion-proof enclosure while preventing air from flowing out, thus preventing the leakage of high-temperature gas from the explosion-proof enclosure and resulting in heat loss.

[0013] Preferably, the inner surface of the explosion-proof box is provided with an insulation layer. The insulation layer helps to enhance the heating effect of the device.

[0014] This invention provides a device for cleaning the inner core of an oxygen humidification bottle, which has the following advantages:

[0015] 1. The cleaning device of this utility model is specially designed to centrally clean and disinfect the inner core of oxygen humidification bottles. The inner core of the used oxygen humidification bottle is placed in a heating box, and the flushing head is directly aligned with the narrow through hole in the inner core body. High-temperature steam is used for disinfection, with a temperature of ≥90℃ and a time of ≥5min. Alternatively, heated air can be used for one-to-one drying. This device can disinfect the interior of multiple inner cores at one time and can also perform specialized drying, achieving efficient and high-quality disinfection and drying.

[0016] 2. This utility model heats the pure water in the heating chamber and the air in the insulation zone simultaneously by heating the resistance wire. The pure water in the heating chamber generates high-temperature water vapor when heated. The high-temperature water vapor is filled into the inner core body by the flushing component and discharged into the explosion-proof cover. At the same time, the exterior and inner tube of the inner core body are rinsed and disinfected at high temperature, making the cleaning more thorough.

[0017] 3. This utility model uses an air pump and a flushing assembly to fill the inner core body with high-temperature gas after rinsing, and uses the high-temperature gas to dry the inside and outside of the inner core body, thereby improving cleaning efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides an oxygen humidification bottle inner core cleaning device, which aims to achieve centralized disinfection and cleaning of multiple oxygen humidification bottles, thereby improving the quality and efficiency of cleaning and disinfection, and meeting the cleaning and disinfection needs of large-scale oxygen inhalation auxiliary equipment in large medical institutions.

[0027] like Figure 1 and Figure 2 As shown, the cleaning device of this utility model comprises an explosion-proof box 1, a heating box 2, a flushing assembly 4, and a fixing assembly 8. An explosion-proof cover 9 is installed on the explosion-proof box 1. The heating box 2 is fixedly installed on the upper part of the interior of the explosion-proof box 1. Below the heating box 2 is a heat preservation zone 3. A heating resistance wire 6 is installed on the lower surface of the heating box 2. An air pump 5 is installed at the bottom of the heat preservation zone 3. Several flushing assemblies 4 are arranged equidistantly on the upper surface of the explosion-proof box 1.

[0028] The flushing assembly 4 includes a flushing head 401 located on the upper surface of the explosion-proof box 1. The bottom of the flushing head 401 is connected to a drying pipe 402, a flushing pipe 403, and an external branch pipe 405 extending into the explosion-proof box 1. The bottom of the external branch pipe 405 is bent and extends into one side of the heating box 2, and its end is connected to an external main pipe 406. The external main pipe 406 is connected to the water spray end of an external fully automatic sterilizer. The bottom of the drying pipe 402 is connected to an air pump 5, and the bottom of the flushing pipe 403 is connected to and communicates with the heating box 2. A first solenoid valve 11 and a second solenoid valve 12 are respectively installed on the drying pipe 402 and the flushing pipe 403. The first solenoid valve 11 controls the opening and closing of the drying pipe 402, and the second solenoid valve 12 controls the opening and closing of the flushing pipe 403. Furthermore, a fixing assembly 8 for connecting and fixing the inner core body 18 is provided on the flushing assembly 4. The purpose is to connect and fix multiple inner core bodies 18 to the flushing head 401 of the flushing assembly 4 respectively, so as to perform cleaning, disinfection and drying operations respectively.

[0029] In this embodiment, as Figure 4 As shown, the drying tube 402 is tightly attached to the inner wall of the explosion-proof box 1 and bypasses the heating box 2. The bottom end of each drying tube 402 is connected by a connecting tube 404, and the connecting tube 404 is connected to the output end of the air pump 5. In a preferred embodiment, the drying tube 402, the rinsing tube 403, the flushing assembly 4, etc., are all made of high-temperature resistant stainless steel. This arrangement avoids damage to the pipes due to excessive temperature of the heating resistance wire 6.

[0030] In this embodiment, the rinsing head 401 is aligned with the port of the inner core body 18. This arrangement allows the rinsing head 401 to be aligned with the port of the inner core body 18, facilitating the rinsing of the inner core body 18.

[0031] In this embodiment, the top edge of the explosion-proof box 1 is provided with a connecting edge 7, and a water guide pipe 10 is provided on one side of the connecting edge 7. A control valve is provided on the water guide pipe 10. By providing the connecting edge 7 to enclose the top of the explosion-proof box 1, water used for rinsing the inner core body 18 is prevented from flowing around and can be discharged through the water guide pipe 10.

[0032] In this embodiment, as Figure 3 As shown, a plurality of fixing grooves 801 corresponding to and cooperating with the rinsing head 401 are provided on the lower surface of the fixing component 8. A through groove 802 is provided at the top center of the fixing groove 801, and fixing holes 803 are provided on the edge of the fixing component 8. Fixing bolts 17 corresponding to and cooperating with the fixing holes 803 are provided on the top of the explosion-proof box 1. As a preferred embodiment, the groove depth of the fixing groove 801 is less than or equal to the sum of the thickness of the rinsing head 401 and the end of the inner core body 18. With this configuration, the end of the inner core body 18 can be fixed to the rinsing head 401 through the fixing groove 801, and the through groove 802 facilitates the passage of the inner core body 18.

[0033] In this embodiment, the top and bottom of the heating box 2 are respectively provided with a water inlet pipe 13 and a drain pipe 14 extending out of the explosion-proof box 1, and the ends of the water inlet pipe 13 and the drain pipe 14 are threaded with sealing caps. The water inlet pipe 13 facilitates the injection of pure water into the heating box 2, and the drain pipe 14 facilitates the discharge of residual water from the heating box 2.

[0034] In this embodiment, a one-way air valve 15 communicating with the insulation zone 3 is provided on one side of the explosion-proof box 1. By providing the one-way air valve 15, air can enter the explosion-proof box 1, while preventing air from flowing out of the explosion-proof box 1, thus preventing the high-temperature gas inside the explosion-proof box 1 from leaking out and causing heat loss.

[0035] In this embodiment, an insulation layer 16 is provided on the inner surface of the explosion-proof box 1. The insulation layer 16 helps to enhance the heating effect of the device.

[0036] When using the cleaning device to disinfect, clean, and dry the inner core of the oxygen humidification bottle, the end of the inner core body 18 needs to be placed on the rinsing head 401 and aligned with it. Through the cooperation of the fixing bolt 17, the wing nut, and the fixing hole 803, the fixing component 8 is used to firmly and tightly fit the inner core body 18 with the rinsing head 401, and the explosion-proof cover 9 is covered and sealed. The sealing method of the explosion-proof cover 9 is the same as that of the pressure cooker top cover, and the explosion-proof cover 9 is provided with the same exhaust hole as the pressure cooker.

[0037] The heating resistance wire 6 is activated, and the heating resistance wire 6 generates heat to heat the heating box 2 and the heat preservation zone 3 simultaneously. In a preferred embodiment, a pressure sensor is installed in the heating box 2. The pure water in the heating box 2 is heated to form high-temperature water vapor. Since the first solenoid valve 11 and the second solenoid valve 12 are closed, water vapor is continuously generated in the heating box 2, increasing the air pressure in the heating box 2, so that the heating box 2 is filled with high-pressure high-temperature water vapor.

[0038] The external fully automatic disinfection machine is started. The fully automatic disinfection machine first uses the external main pipe 406 and external branch pipe 405 to flush the interior of the inner core body 18 with flowing water through the flushing head 401. The flowing water removes foreign objects on the inner wall of the inner core body 18. The flowing water overflows from the top of the inner core body 18 to clean the outer wall of the inner core body 18. The fully automatic disinfection machine then uses cleaning water containing chemical cleaning agent to rinse the inner and outer walls of the inner core body 18 with the same water, achieving the effect of pre-rinsing and washing. Since pre-rinsing and washing require a large amount of water flow, the water pipe 10 must be kept in a flowing state at all times to facilitate timely drainage of water. The water pipe 10 is closed after the pre-rinsing and washing are completed.

[0039] When the pressure inside the heating chamber 2 reaches a certain level as measured by the pressure sensor, the second solenoid valve 12 is opened. High-pressure, high-temperature water vapor enters the flushing head 401 through the flushing pipe 403, and then enters the inner tube of the inner core body 18 through the flushing head 401. The continuously flowing high-pressure, high-temperature water vapor is used to disinfect the inner tube of the inner core body 18 at high temperature. The high-temperature water vapor passing through the inner core body 18 fills the explosion-proof cover 9, creating a high-pressure, high-temperature environment inside the explosion-proof cover 9, thereby disinfecting the surface of the inner core body 18 at high temperature.

[0040] After the high-temperature disinfection is completed, the second solenoid valve 12 is closed, and the gas inside the explosion-proof cover 9 is discharged through the exhaust hole at the top of the explosion-proof cover 9. The water pipe 10 is opened to drain the water inside the explosion-proof cover 9. The first solenoid valve 11 is opened, and the air pump 5 is started. The air pump 5 sends the heated air in the insulation zone 3 through the drying pipe 402 to the rinsing head 401. The air enters the inner tube of the inner core body 18 through the rinsing head 401. The hot air dries the residual moisture inside the inner tube of the inner core body 18. The hot air passing through the inner core body 18 fills the explosion-proof cover 9, thereby indirectly drying the surface of the inner core body 18, completing the disinfection and drying process of the inner core body 18.

[0041] Finally, release the fixing component 8 from the inner core body 18, remove the inner core body 18, and if there is some residual moisture on the surface of the inner core body 18, wipe it dry with sterile gauze, take it out and place it in a special container for later use.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
