Abstract
Description
Technical Field
[0001] This utility model relates to the field of regulating cabin technology, specifically a medical modular ecological regulating cabin. Background Technology
[0002] Medical ecological conditioning chambers (such as hyperbaric oxygen chambers and isolation treatment chambers) have strict requirements for the air quality inside the chamber. They must effectively remove viruses, bacteria, PM2.5 and volatile organic compounds (VOCs) from the air in order to reduce the risk of cross-infection and meet medical cleanliness standards.
[0003] For example, the authorized patent document with application number CN202222817999.1 discloses a multifunctional air pressurization chamber, belonging to the field of pressurization chamber technology. It includes a main chamber and a secondary chamber, with the secondary chamber located inside the main chamber on one side. A double-layered door connects the main and secondary chambers. The main chamber has two rows of single soft seats, and the secondary chamber has beds on both sides. Doors are located at the ends of both the main and secondary chambers. Both the main and secondary chambers have air supply systems, lighting, and fire sprinklers on their tops. The lighting and fire sprinklers are arranged linearly on pipes. Each single seat in the main chamber has a negative pressure suction device and an oxygen intake / exhaust device. Compared to general hyperbaric oxygen chambers that only treat hyperbaric oxygen therapy, this multifunctional air pressurization chamber adds the function of treating decompression sickness, expanding the treatment guarantee for decompression sickness in medical hyperbaric oxygen chambers. This pressurization chamber can treat both the indications of medical oxygen chambers and decompression sickness, meeting multiple treatment requirements.
[0004] The aforementioned patent uses a negative pressure suction device and an oxygen intake / exhaust device next to each single seat in the main cabin. However, the pressurized cabin does not have an air intake filtration system, and outside air enters the cabin directly, which may carry viruses or dust, increasing the risk of infection. In addition, the filter replacement time is relatively long. Therefore, we need to provide a medical modular ecological regulation cabin. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model provides a technical solution: a modular medical ecological regulation cabin, comprising:
[0025] The chamber 1 and the filter 2 include an air intake mechanism 21, a rotating part 22 and a filter element 23. An air intake mechanism 21 that works with the filter element 23 is provided on one side of the chamber 1. The air intake mechanism 21 is installed on one side of the chamber 1. The rotating part 22 is used to rotate multiple filter elements 23.
[0026] Specifically, a filter 2 is provided on one side of the cabin 1 to adsorb external gas into the cabin 1 and to filter the gas entering the cabin 1, intercepting viruses and bacteria. At the same time, the filter element 23 that has been used for a period of time can be replaced with a new filter element 23 in a very short time. The air intake mechanism 21 introduces external air into the filter element 23, and multiple filter elements 23 are distributed on the rotating part 22. The used filter element 23 can be rotated out by the rotating part 22, and the unused filter element 23 can be rotated into the air intake mechanism 21 for use. An exhaust pipe is provided on the other side of the cabin 1 to promote the circulation of air in the cabin 1.
[0027] Among them, filter element 23 is an integrated multi-layer filter element 23, which includes a pre-filtration layer, a HEPA high-efficiency filtration layer and an activated carbon adsorption layer, which can perform step-by-step purification of the outside air:
[0028] Pre-filter layer: intercepts large particles of dust, hair and other impurities in the air, extending the service life of the core filter element 23;
[0029] HEPA filter element 23: Filters viruses and bacteria aerosols larger than 0.3μm with an efficiency of ≥99.97%, meeting medical cleanliness standards (such as GB 50333-2013 "Technical Specification for Clean Operating Room Buildings in Hospitals"), effectively blocking the cross-infection path of airborne diseases;
[0030] Activated carbon layer: adsorbs volatile organic compounds (VOCs), odors, and residual disinfectant gases in the air, ensuring that the air inside the cabin meets medical-grade freshness standards.
[0031] The air intake mechanism 21 includes a centrifugal fan 211, an air hood 212, a pipe body 213, and a sealing element 210. The sealing element 210 is used for the two air hoods 212 to move closer to each other or further away from each other. The two air hoods 212 are located at the air inlet end and the air outlet end of the filter element 23, respectively. The centrifugal fan 211 is connected to the upper air hood 212, the pipe body 213 is connected to the lower air hood 212, and the pipe body 213 is connected to the chamber 1.
[0032] It is worth noting that the seal 210 is installed on one side of the chamber 1. The seal 210 can control the two air hoods 212 to move closer or further apart from each other. Of the two air hoods 212, the upper air hood 212 is connected to the exhaust end of the centrifugal fan 211, and the air inlet end of the centrifugal fan 211 is equipped with a protective net. The lower air hood 212 is connected to the pipe 213. The pipe 213 is embedded in one side of the chamber 1 to send the filtered air into the chamber 1. Both air hoods 212 are conical hoods. The larger side of the surface of the air hood 212 can cover the end of the filter element 23, and the filter element 23 is installed between the two hoods.
[0033] The sealing element 210 includes a base 2101, a double threaded rod 2102, an actuator 2103, and a push plate 2104. Push plates 2104 are provided on the surfaces of the two air hoods 212. The double threaded rod 2102 is rotatably installed inside the base 2101. The two push plates 2104 are located on both sides of the surface of the double threaded rod 2102, and the actuator 2103 is provided at the upper end of the double threaded rod 2102.
[0034] It should be noted that the base 2101 is fixed to the side of the chamber 1 by bolts on one side. The double threaded rod 2102 is rotatably installed in the base 2101. The double threaded rod 2102 is rotated by the driver 2103, which can make the two push plates 2104 move away from each other or move closer to each other. One side of the push plate 2104 is welded to the surface of the air cover 212, so that the air cover 212 and the push plate 2104 move together. When the filter element 23 needs to be replaced, the driver 2103 is started to rotate the double threaded rod 2102, which moves the two air covers 212 away from each other and moves the new filter element 23 between the two air covers 212.
[0035] The lifespan determination of filter element 23 is based on the selected filter element 23's service life and adjusted according to environmental conditions. The filter element 23 is replaced after a set number of hours, for example, three hours later. First, the driver 2103 is started to rotate the double threaded rod 2102, separating the two air covers 212. Then, the motor 224 is started to rotate the drive rod 223, rotating the stacking rack 221, which can hold up to six filter elements 23. The used filter element 23 is then rotated away, and a new filter element 23 is rotated to the next position. Between the air hoods 212, and with the motor 224 being a stepper motor 224, the six filter elements 23 are evenly distributed on the surface of the stacking rack 221. The rotation angle of the motor 224 is set to a fixed value of 30°, which enables the new filter element 23 to be accurately placed between the two air hoods 212. At this time, the driver 2103 is started to bring the two air hoods 212 closer together and seal the two ends of the filter element 23. The staff needs to replace the six filter elements 23 regularly. The setting of six filter elements 23 can avoid replacing the filter elements 23 one by one.
[0036] Both air hoods 212 are fixedly installed with limit rings 3, and each of the two limit rings 3 is provided with a sealing ring 4 on an adjacent side. The sealing ring 4 is a rubber ring.
[0037] Furthermore, the outer edge of the limiting ring 3 is welded to the inner wall of the air cover 212, and the rubber ring is fixed to one side of the limiting ring 3. The rubber ring is located inside the air cover 212, close to the filter element 23, so that the sealing ring 4 can fit the end of the filter element 23, thus sealing the connection between the air cover 212 and the filter element 23. The centrifugal fan 211 draws external air into the upper air cover 212, filters it inside the filter element 23, and then enters the lower air cover 212, finally entering the cabin 1 through the air pipe.
[0038] The rotating component 22 includes a stacking rack 221, a fixed seat 222, a drive rod 223 and a motor 224. The drive rod 223 is rotatably installed in two fixed seats 222. Both fixed seats 222 are installed on one side of the cabin 1. The drive rod 223 is located at the axis of the stacking rack 221. The motor 224 is provided at the lower end of the drive rod 223.
[0039] It is worth noting that the starter motor 224 can drive the drive rod 223 to rotate. The drive rod 223 cannot be height adjusted. The drive rod 223 is welded to the axis of the stacking rack 221. The rotation of the drive rod 223 drives the stacking rack 221 to rotate, which in turn rotates the six evenly distributed filter elements 23 on the surface of the stacking rack 221. The motor 224 is a stepper motor 224, which can precisely control the angle of each rotation, remove the used filter elements 23, and put in the new filter elements 23. One end of each of the two fixing brackets is welded to the surface of the chamber 1 for support.
[0040] The stacking rack 221 has several circular grooves 5 for installing filter elements 23, and the surface of the filter element 23 is integrally machined with a positioning ring 6;
[0041] The filter element 23 has a positioning ring 6 welded on its surface. When the filter element 23 is inserted into the inner circular groove 5 of the stacking cylinder, the positioning ring 6 is located at the top of the stacking cylinder, which can limit the position of the filter element 23 and prevent it from being mistaken. A cabinet is provided on one side of the chamber 1. The filter 2 is placed in the cabinet, which can protect the filter 2 and protect the clean filter element 23.
[0042] A protective cover 7 for protecting the double threaded rod 2102 is fixedly installed inside the base 2101. The protective cover 7 is located between the double threaded rod 2102 and the air cover 212, and the surface of the protective cover 7 is in sliding fit with the two push plates 2104.
[0043] Specifically, a protective cover 7 is set on one side of the double threaded rod 2102. The protective cover 7 is located between the double threaded rod 2102 and the air cover 212 to protect the double threaded rod 2102 and prevent debris from accumulating on the surface of the double threaded rod 2102. The double threaded rod 2102 also has a self-locking function.
[0044] A corrugated pipe 8 is provided inside the pipe body 213;
[0045] The flexibility of the corrugated pipe 8 allows the air cover 212 to move away from or closer to the pipe body 213, avoiding a fixed connection between the pipe body 213 and the air cover 212, which would prevent it from moving. The corrugated pipe 8 is usually made of stainless steel or corrosion-resistant flexible material, which is not prone to aging after long-term expansion and contraction.
[0046] The motor 224, driver 2103, filter element 23 and centrifugal fan 211 involved in this application can all be purchased online. They are all implemented using existing mature technologies and controlled by an external controller. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.
[0047] This device draws in outside air into the upper air hood 212 by starting the centrifugal fan 211. The air is then filtered inside the filter element 23 before entering the lower air hood 212 and finally entering the chamber 1 through the air pipe. When replacing the filter element 23, the driver 2103 is first started to rotate the double threaded rod 2102, separating the two air hoods 212. At this time, the motor 224 is started to rotate the drive rod 223, rotating the stacking rack 221. The stacking rack 221 can hold up to six filter elements 23. The used filter element 23 is rotated out, and the new filter element 23 is rotated between the two air hoods 212. The motor 224 is a stepper motor 224. The six filter elements 23 are evenly distributed on the surface of the stacking rack 221. By setting a fixed rotation angle of the motor 224, the new filter element 23 can be accurately placed between the two air hoods 212. At this time, the driver 2103 is started to bring the two air hoods 212 closer together and seal the two ends of the filter element 23.
[0048] 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.
