A disinfection device for a hyperbaric oxygen chamber

Abstract

This invention discloses a disinfection device for a hyperbaric oxygen chamber, comprising: a motor mounted on the outer wall of the chamber; a pressure-resistant, magnetically permeable sealing plate mounted on the observation window opening of the chamber; a power generation device mounted on the inner wall of the chamber; and an ozone generator mounted on the power generation device. The motor and the power generation device are connected via a magnetic coupling, and the ozone generator is electrically connected to the power generation device. This invention directly installs the disinfection device inside the hyperbaric oxygen chamber, requiring only modification to the existing observation window without any destructive alterations to the chamber structure. This ensures the safety of the hyperbaric oxygen chamber during use after the installation of this disinfection device. During disinfection, there is no need to pull a separate power cord. Furthermore, because the chamber door can be closed for disinfection (which would prevent complete closure if the power cord were pulled), the ozone concentration inside the chamber can be rapidly increased, preventing ozone leakage and improving disinfection efficiency.

Description

Technical Field

[0001] This invention relates to the field of disinfection equipment technology, and more specifically, to a disinfection device for a hyperbaric oxygen chamber. Background Technology

[0002] In recent years, with the improvement of medical understanding and technology, hyperbaric oxygen therapy has been widely used in clinical practice to treat a variety of diseases, and hyperbaric oxygen chambers are becoming increasingly popular in various medical facilities. A hyperbaric oxygen chamber is a special type of sealed pressure vessel for human use. During hyperbaric oxygen therapy, the pressure inside the chamber is higher than one atmosphere. The patient is sealed inside the chamber, and after treatment, the air inside is polluted and has a strong odor, requiring disinfection and deodorization procedures.

[0003] Currently, common disinfection methods for hyperbaric oxygen chambers include: chlorine-based disinfectant spraying and wiping, ozone disinfection, and ultraviolet irradiation. Chlorine-based disinfectant spraying and wiping have drawbacks such as a relatively large workload and ineffective disinfection of the chamber's piping and interior decorative layers. Ozone disinfection and ultraviolet irradiation are achieved using portable ozone sterilizers and portable ultraviolet lamps, requiring the use of extension cords or power strips to bring 220V AC power into the hyperbaric oxygen chamber. Damage to the power cord could cause the hyperbaric oxygen chamber and its auxiliary equipment to become electrified, posing a risk of electric shock. Furthermore, ultraviolet irradiation also suffers from the drawback of ineffective disinfection of the chamber's piping and interior decorative layers.

[0004] Therefore, how to install a safe and efficient in-chamber disinfection device in a hyperbaric oxygen chamber is the technical problem that this invention aims to solve.

[0005] Therefore, it is necessary to propose a disinfection device for hyperbaric oxygen chambers to at least partially solve the problems existing in the prior art. Summary of the Invention

[0009] Preferably, the power generation equipment is further provided with fan blades, which are located inside the ozone generator, and the second disk, the rotor of the power generation equipment, and the fan blades are connected to the same shaft.

[0010] Preferably, the ozone generator is provided with an air inlet and an air outlet, and the fan blade is located at the air inlet of the ozone generator.

[0011] Preferably, the power generation equipment is externally fitted with an insulating encapsulation assembly, a pressure ring is provided between the insulating encapsulation assembly and the flange on the observation window located inside the cabin, and the insulating encapsulation assembly and the flange on the observation window located inside the cabin are connected by quick-release fasteners.

One side of the buckle is provided with an annular groove, and the pressure ring is connected to the buckle through the annular groove. The other side of the buckle is a bevel and is movably connected to the quick-release fastener through the bevel.

[0013] Preferably, the retaining ring is located on one side of the inclined surface and is provided with an inner retaining ring and an outer retaining ring. The inner diameter of the inner retaining ring is the same as the inner diameter of the retaining ring. The outer retaining ring is located outside the inner retaining ring. The outer diameter of the ring groove is larger than the outer diameter of the outer retaining ring. The insulating ring is disposed between the outer retaining ring and the inner retaining ring. The elastic ring is sleeved on the outside of the outer retaining ring. The outer retaining ring is provided with at least four openings, and the retaining ring is provided with slots at the opening positions. The slots are positioned corresponding to and communicating with the ring groove. One end of the locking member is engaged with the end of the insulating ring, and the other end is inserted into the retaining ring through the slot. The inner sidewall of the locking member abuts against the outer sidewall of the insulating ring through the opening. The outer sidewall of the locking member abuts against the inner wall of the elastic ring, and the locking member abuts against the end of the elastic ring.

[0014] Preferably, the locking member includes a pressure plate that abuts against the outer wall of the insulating ring; a plug disposed at one end of the pressure plate for insertion into the slot; a hook disposed at the other end of the pressure plate for engaging with the end of the insulating ring; and an abutment plate disposed on the side of the pressure plate and bent away from the insulating ring for abutting against the elastic ring.

[0018] During hyperbaric oxygen chamber disinfection, the chamber door can be closed, and the motor can be started. The motor, via a magnetic coupling, drives the power generation equipment located inside the chamber, generating electricity to power the ozone generator.

The magnetic coupling enables the power generation equipment to generate its own electricity, eliminating the need for a separate power cord during disinfection. Furthermore, because the chamber door can be closed for disinfection (which would prevent complete closure if the power cord is pulled), the ozone concentration inside the chamber can be rapidly increased, preventing ozone leakage and improving disinfection efficiency.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0034] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0035] like Figures 1-11 As shown, the present invention provides a disinfection device for a hyperbaric oxygen chamber, comprising: a motor 1 installed on the outer wall of the chamber, a pressure-resistant magnetic sealing plate 2 installed on the observation window opening of the chamber, a power generation device 3 installed on the inner wall of the chamber, and an ozone generator 4 installed on the power generation device 3. The motor 1 and the power generation device 3 are connected by a magnetic coupling 5, and the ozone generator 4 is electrically connected to the power generation device 3.

[0036] The working principle and beneficial effects of the above technical solution are as follows: During hyperbaric oxygen chamber disinfection, the chamber door can be closed, and then motor 1 can be started. Motor 1 will drive the power generation device 3 located inside the chamber through magnetic coupling 5, thereby providing power to the ozone generator 4. Because this invention directly installs the disinfection equipment inside the hyperbaric oxygen chamber, and only requires modification to the existing observation window of the hyperbaric oxygen chamber without any additional destructive modifications to the chamber body, the safety of the hyperbaric oxygen chamber during use can be ensured after the installation of this invention, and the service life of the hyperbaric oxygen chamber will not be reduced due to the modification of the disinfection device. The power generation device 3 generates its own electricity through magnetic coupling 5, so that there is no need to pull the power cord separately during disinfection. At the same time, because the chamber door can be closed for disinfection (if the power cord is pulled, the chamber door cannot be completely closed), the ozone concentration inside the chamber can be quickly increased, ozone leakage is avoided, and the disinfection efficiency is improved.

[0037] In one embodiment, the magnetic coupling 5 comprises a first disk 51 mounted on the output shaft of the motor 1 and a second disk 52 mounted on the power generation device 3 and connected to the rotor of the power generation device 3. A gap is reserved between the first disk 51 and the pressure-resistant magnetic sealing plate 2, and a gap is also reserved between the second disk 52 and the pressure-resistant magnetic sealing plate 2. The power generation device 3 is also equipped with a fan blade 31 located within the ozone generator 4, and the second disk 52, the rotor of the power generation device 3, and the fan blade 31 are connected to the same shaft. The ozone generator 4 is provided with an air inlet 41 and an air outlet 42, and the fan blade 31 is located at the air inlet 41 of the ozone generator 4.

[0038] The working principle and beneficial effects of the above technical solution are as follows: Since the observation windows on the bulkhead are usually circular, this embodiment provides a magnetic coupling 5 that can be applied to circular observation windows. Specifically, both the first disk 51 and the second disk 52 are circular. The observation window can be replaced by a pressure-resistant magnetically permeable sealing plate 2 (replacement is optional depending on actual needs, as the observation window itself is made of a high-pressure resistant material and can be used as the pressure-resistant magnetically permeable sealing plate 2). To further improve ozone diffusion efficiency, a fan blade 31 is added inside the air inlet 41 of the ozone generator 4 to increase the air intake and ozone discharge rate. Simultaneously, the fan blade 31, the rotor of the power generation device 3, and the second disk 52 are mounted on the same shaft. When the magnetic coupling 5 rotates, it drives the fan blade 31 to rotate as well, thus eliminating the need for a separate drive device for rotating the fan blade 31.

[0039] In one embodiment, the power generation equipment 3 is externally fitted with an insulating encapsulation assembly 6, and a pressure ring 8 is provided between the insulating encapsulation assembly 6 and the flange 7 on the observation window located inside the cabin. The insulating encapsulation assembly 6 and the flange 7 on the observation window located inside the cabin are connected by a quick-release fastener 9.

[0040] The working principle and beneficial effects of the above technical solution are as follows: Since all sources of ignition must be eliminated during the use of a hyperbaric oxygen chamber, although this invention can achieve power generation isolated from the outside world through the magnetic coupling 5, the power generation device 3 itself is a hazard source when using the hyperbaric oxygen chamber. Therefore, to further adapt this disinfection device to hyperbaric oxygen chambers, we provide the following two implementation methods: First, provide insulation protection for the power generation device 3 located inside the chamber (the part located inside the chamber does not need to be removed when using the hyperbaric oxygen chamber). Even if the power generation device 3 is accidentally triggered by the motor 1, it can be insulated and sealed from the chamber through the insulating encapsulation component 6, reducing the probability of safety accidents. Second, design the part located inside the chamber for quick disassembly. During disinfection, the part located inside the chamber is quickly connected to the flange 7 on the observation window inside the chamber via quick-release fasteners 9. During high-pressure treatment, the part located inside the chamber is removed, thereby preventing accidental power generation by the power generation device 3 due to accidental triggering of the motor 1.

[0041] In one embodiment, the insulating encapsulation assembly 6 comprises a retaining ring 61 sleeved on the outer wall of the power generation device 3, an insulating ring 62 sleeved on the outer wall of the power generation device 3, an elastic ring 63 sleeved on the retaining ring 61, and a plurality of clips 64 connected to the retaining ring 61 for fixing the insulating ring 62 and the elastic ring 63. One side of the retaining ring 61 is provided with an annular groove 611, and the pressure ring 8 is connected to the retaining ring 61 through the annular groove 611. The other side of the retaining ring 61 is a bevel, and is movably connected to the quick-release fastener 9 through the bevel.

[0042] The retaining ring 61 is located on one side of the inclined plane and is provided with an inner retaining ring 612 and an outer retaining ring 613. The inner diameter of the inner retaining ring 612 is the same as the inner diameter of the retaining ring 61. The outer retaining ring 613 is located outside the inner retaining ring 612. The outer diameter of the annular groove 611 is larger than the outer diameter of the outer retaining ring 613. The insulating ring 62 is disposed between the outer retaining ring 613 and the inner retaining ring 612. The elastic ring 63 is sleeved on the outside of the outer retaining ring 613. The outer retaining ring 613 is provided with at least four openings, and... The buckle 61 has a slot 614 at the opening position. The slot 614 is positioned corresponding to and communicates with the annular groove 611. One end of the locking member 64 is engaged with the end of the insulating ring 62, and the other end is inserted into the buckle 61 through the slot 614. The inner sidewall of the locking member 64 abuts against the outer sidewall of the insulating ring 62 through the opening. The outer sidewall of the locking member 64 abuts against the inner wall of the elastic ring 63, and the locking member 64 abuts against the end of the elastic ring 63.

[0043] The locking member 64 includes a pressure plate 641 that abuts against the outer wall of the insulating ring 62; a plug 642 disposed at one end of the pressure plate 641 for insertion into the slot 614; a hook 643 disposed at the other end of the pressure plate 641 for engaging with the end of the insulating ring 62; and an abutment plate 644 disposed on the side of the pressure plate 641 and bent away from the insulating ring 62 for abutting against the elastic ring 63.

[0044] The working principle and beneficial effects of the above technical solution: Since the above embodiments provide two implementation methods and there is no conflict between them, the insulation encapsulation component 6 described in this embodiment is a structural design that is simultaneously adapted to the quick-release fastener 9 (mainly the inclined surface design of the buckle 61, which can be directly fixed to the flange when the quick-release fastener 9 is not used), which does not mean that the insulation encapsulation component 6 can only be implemented in this way.

[0045] During installation, first install the disinfection devices located inside the chamber (such as power generation equipment 3, ozone generator 4, etc.) into the retaining ring 61. Then, insert the insulating ring 62 between the inner retaining ring 612 and the outer retaining ring 613. A limiting strip can be provided between the inner retaining ring 612 and the outer retaining ring 613, and a limiting groove is provided at the end of the insulating ring 62 to facilitate insertion and limiting. The insulating ring 62 can be elastic, such as insulating rubber, or rigid, such as ceramic, resin, etc.

[0046] After the insulating ring 62 is inserted, the clip 64 is inserted into the slot 614, and the hook 643 is hooked onto the end of the insulating ring 62 to limit its movement and prevent it from shaking. The plug 642 is a tapered plug with an opening groove in the middle for easy insertion and removal. Disassembly can be facilitated by pinching the base of the plug 642 (or by pinching the tapered end from inside the slot 614 with tweezers). A protruding limiting block can be provided on the pressure plate 641, allowing the hook 643 and the limiting block to limit both ends of the insulating ring 62.

[0047] After the insulating ring 62 is secured by the clip 64, the elastic ring 63 is fitted onto the outer retaining ring 613. At this time, the elastic ring 63 can compress the pressure plate 641, thereby pressing the pressure plate 641 onto the insulating ring 62, thus securing the insulating ring 62. If the insulating ring 62 is made of an elastic material, under the compression of the elastic ring 63, the insulating ring 62 will adhere tightly to the outer wall of the inner retaining ring 612.

[0048] Through the combined action of the clip 64 and the elastic ring 63, the insulating ring 62 can be limited in both the axial and radial directions.

[0049] Finally, the abutment plate 644 is bent in the opposite direction to snap and fix the end of the elastic ring 63. This completes the installation of the insulating encapsulation assembly 6.

[0050] After the insulating encapsulation assembly 6 is installed, it can be connected to the disinfection device and installed on the flange using the quick-release fastener 9.

[0051] By installing an insulating ring 62 on the outside of the sterilization device, especially the power generation device 3, zero contact between the power generation device 3 and the inner wall of the hyperbaric oxygen chamber is achieved (the power generation device 3 is connected to the insulating encapsulation assembly 6 via the insulating ring 62, and is connected to the flange of the chamber wall via the insulating encapsulation assembly 6). Therefore, even without disassembling the sterilization device inside the chamber, if the motor 1 switch is accidentally activated during hyperbaric therapy, causing the power generation device 3 to generate electricity, there will be no leakage or sparking. Furthermore, the insulating ring 62 will not shift due to vibration of the power generation device 3 when the sterilization device is started.

[0052] In one embodiment, the flange 7 on the observation window located inside the cabin has a flat side with an annular groove adapted to the annular groove 611, and a sloped side. The quick-release fastener 9 consists of an upper fastener 91 with an arc-shaped groove at the bottom, a lower fastener 92 with an arc-shaped groove at the top, and a connecting strip 93 for connecting the upper fastener 91 and the lower fastener 92. One end of the connecting strip 93 is axially connected to the upper fastener 91, and the other end is axially connected to the lower fastener 92. A connecting rod 94 is axially connected to the upper fastener 92, and a roller 95 is axially connected to the end of the connecting rod 94. The side of the upper fastener 91 away from the lower fastener 92 has a groove 96 for engaging the roller 95.

[0053] The upper fastener 91 has a toothed slope on the side away from the lower fastener 92. The slope extends from the end of the upper fastener 91 into the groove 96. The roller 95 has teeth that are adapted to the slope.

[0054] The working principle and beneficial effects of the above technical solution: In this embodiment, a quick-disassembly implementation method is provided. In this implementation method, both the flange and the buckle 61 need to have beveled surfaces, and the side walls of the arc-shaped grooves of the upper buckle 91 and the lower buckle 92 are also beveled surfaces. At the same time, the upper buckle 91 and the lower buckle 92 are located at the two ends of the connecting strip 93 respectively, and there is a certain distance between the two shaft connections, so that the roller 95 can have a certain degree of flexibility when it rolls into the groove 96.

[0055] Taking a toothed roller 95 as an example, firstly, a pressure ring 8 is installed in the annular groove 611 of the retaining ring 61. Then, the retaining ring 61 is fastened onto the flange, and the pressure ring 8 also enters the annular groove of the flange. The pressure ring 8 can be designed with a limiting protrusion on the contact surface, and the limiting protrusion can be engaged with the annular groove 611 and the annular groove to achieve a snap-fit ​​connection. The pressure ring 8 enables an insulating and sealing connection between the retaining ring 61 and the flange.

[0056] Place the flange and retaining ring 61 into the arc-shaped grooves of the upper and lower fasteners, and flip the connecting rod 94 so that the roller 95 engages with the teeth on the slope of the lower fastener 92 (e.g., Figure 9 As shown in Figure A, rotating roller 95 moves towards groove 96, the upper and lower fasteners will close together, and at the same time, the inner wall of the arc-shaped groove will press against the inclined surface of flange and retaining ring 61 (as shown in Figure A). Figure 10 As shown), this compresses the pressure ring 8 until the roller 95 enters the groove 96 (as shown). Figure 9 As shown in Figure B), under the action of pressure ring 8, the inclined surfaces of flange and retaining ring 61 will press against each other against the arc-shaped grooves of the upper and lower fasteners, and the connecting rod 94 can clamp the upper and lower fasteners together (as shown in Figure B). Figure 9 (As shown in C).

[0057] The same principle applies during disassembly.

[0058] The above structural design enables rapid connection between the flange and the insulating encapsulation assembly 6, while achieving both sealing and insulation effects.
