Description

Technical Field

[0001] This utility model relates to an airborne high-level ophthalmic clean operating room. Background Technology

[0002] According to survey data, among eye diseases in my country, floaters, dry eye, glaucoma, and blurred vision are the most prevalent, affecting approximately 920 million people (as of 2018), accounting for 65.95% of the total population, and the number continues to increase. The prevalence of floaters in my country is 20%–30%, while the number of dry eye patients exceeds 360 million, meaning that on average, one in four people suffers from dry eye. Cataracts are another common eye condition, affecting 220 million people globally according to the World Health Organization (WHO). Cataracts not only impair vision but also severely impact quality of life. Most patients live in developing countries or underdeveloped regions. Currently, cataract treatment primarily involves surgical removal of the cloudy lens and implantation of an artificial lens to restore vision. The mainstream surgical method is phacoemulsification combined with artificial lens implantation, which has advantages such as small incisions and rapid recovery; the entire procedure typically takes only 5–10 minutes. However, it places high demands on the surgical team, requiring not only experienced surgeons but also a Class I ophthalmic clean operating room as specified in the national standard GB 50333 "Technical Specification for Clean Operating Room Buildings in Hospitals".

[0003] To bring light and hope to these patients, my country has developed mobile ophthalmic operating rooms mounted on trains or large trucks to perform surgeries for cataract patients or those with other eye diseases in underdeveloped areas, restoring their sight and giving them confidence and courage in life. Many patients who lost their ability to work due to cataracts are able to return to normal life after surgery, which is of great significance to individuals and their families. To extend medical services to more remote or isolated areas, there have been attempts to deploy simplified ophthalmic clinical treatments on helicopters. However, the cramped cabin space of rotorcraft helicopters makes it impossible to create a clean surgical environment, limiting the ability to perform complex ophthalmic surgeries such as cataract surgery, thus restricting medical service capacity. Furthermore, rotorcraft helicopters have limited range, covering areas within a 200km radius, which is insufficient for remote regions.

[0004] To serve less developed areas, train hospitals and mobile hospitals already exist. To extend medical services to even more remote or isolated regions, attempts have been made to deploy simplified ophthalmic clinical treatments on helicopters. However, the cramped cabin space of rotorcraft helicopters limits the implementation of clean ophthalmic surgical environments, thus restricting medical service capacity. Fixed-wing jet aircraft, with their greater space, can meet these requirements. While some overseas ophthalmic hospitals are mounted on MD-10 wide-body cargo planes, they lack high-level, dedicated clean ophthalmic operating rooms.

[0005] Therefore, in response to the above issues, a high-level airborne ophthalmic clean operating room is proposed for ordinary large passenger aircraft. Utility Model Content

[0006] The purpose of this invention is to overcome the existing defects and provide the environmental control required for high-level clean ophthalmic surgery on air, which can provide a high-level clean ophthalmic operating room for the cabin of ordinary large passenger aircraft.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an airborne high-level ophthalmic clean operating room, including a cabin, with a front partition and a rear partition installed inside the cabin to separate the front cabin treatment area, the middle cabin operating area and the rear cabin equipment area; The ceiling panel at the top of the middle surgical area separates the upper static pressure box, which includes the air outlet of the cabin air conditioning system and an independent air supply assembly. The air outlet of the air supply assembly is embedded in the ceiling panel to deliver clean and sterile vertical unidirectional airflow to the middle surgical area.

[0008] Preferably, the air supply assembly consists of a fan box and a filter box; the fan box is equipped with an EC low-noise fan, and the filter box is equipped with a high-efficiency filter; the air supply assembly and the air outlet of the cabin air conditioning system are located in the same static pressure box, and the independent air supply assembly draws in the air supply from the air outlet of the cabin air conditioning system and the air conditioning air infiltrating into the front and rear compartments through the perforated plates on the upper part of the front and rear partitions, and delivers clean vertical unidirectional airflow to the operating area in the middle compartment.

[0009] Preferably, the upper and lower parts of the front partition and the rear partition are perforated wall panels, the middle part is a solid wall panel, and the middle is filled with a non-woven filter material layer.

[0010] Preferably, the front partition is provided with a front door for the operating room; the rear partition is provided with a rear door for the operating room.

[0011] Preferably, the lower ends of the front bulkhead and the rear bulkhead are fixedly connected to the existing fixed guide rails on the cabin floor via U-shaped grooves; the ceiling panel is fixedly connected with bolts for hanging luggage; and the side walls of the ceiling panel, the front bulkhead, and the rear bulkhead are fixedly sealed to the inner wall of the cabin with silicone sealant.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This onboard high-level clean operating room for ophthalmology is divided into a front cabin treatment area, a middle cabin operating area, and a rear cabin equipment area by setting a front and rear partition inside the cabin. The air outlet of the independent air supply component at the top of the middle cabin operating area is embedded in the ceiling panel to deliver clean vertical unidirectional airflow to the middle cabin operating area, which meets the actual situation of the cabin space of domestic passenger aircraft. Two partitions with perforated plates at the top and bottom form a three-compartment layout in the cabin, retaining the basic departments and configurations and having corresponding clinical functions. The middle operating area meets the requirements of a high-level Class I ophthalmology-specific clean operating room. The ceiling panel at the top forms a static pressure box above the operating area, with a built-in air supply component with a built-in fan, eliminating the need for air duct connection. The air supply duct of the ground-based air conditioning unit is connected to the dedicated air conditioning interface of the passenger aircraft. The fresh air conditioning airflow passes through the original air conditioning duct of the passenger aircraft, is sterilized and dust-removed by the original high-efficiency filter, and is delivered out through the upper air supply vent. At this time, the return air vent of the cabin air conditioning system becomes ineffective. The air supply unit draws in the air from the air outlets inside the static pressure box, as well as the air conditioning air from the front and rear compartments that infiltrates through the perforated plates at the top of the front and rear partitions, and then delivers it to the operating area. This creates a vertical, clean, unidirectional airflow in the operating area, meeting the requirements of a Class I clean operating room.

[0013] This onboard ophthalmic clean operating room is housed within the cabin of a large passenger aircraft, enabling it to serve as an airborne hospital and facilitating treatment for patients from different regions. Utilizing rapidly assembled and disassembled panels and independent air supply components, it requires no ductwork and can be quickly constructed or dismantled on the aircraft. It is equipped with Class I clean operating rooms as defined in the national standard GB 50333, "Technical Specification for Clean Operating Room Construction in Hospitals." After the aircraft lands and parks on the designated apron, the onboard hospital can be rapidly constructed overnight, allowing medical services to commence the following day. After completing its designated tasks, it can be quickly dismantled without causing any damage or alteration to the cabin, meeting airworthiness requirements and allowing the aircraft to continue its flight missions.

[0016] 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.

[0017] like Figure 1-2 As shown, the airborne ophthalmic clean operating room includes a cabin 1. Inside the cabin 1, a front partition 2 and a rear partition 3 are installed to separate the front cabin treatment area 4, the middle cabin operating area 5, and the rear cabin equipment area 6. The static pressure box at the top of the middle cabin operating area 5 has a built-in air supply assembly 13, which is used to deliver clean vertical unidirectional airflow to the middle cabin operating area 5.

[0018] Specifically, the rear cabin equipment area 6 is equipped with handwashing and changing facilities, medical equipment cabinets, and isolation transformers; the middle cabin is the operating room, and the front cabin has outpatient, examination, and surgical waiting areas. The front and rear cabins can also be swapped depending on the aircraft type and clinical requirements. The rear cabin equipment area 6 is the pre-operation room, equipped with handwashing facilities for surgical personnel, storage boxes for sterile supplies required for surgery, medicine cabinets, isolation transformers, and other electromechanical equipment.

[0019] Specifically, the central operating area 5 can be used for other non-ophthalmic surgeries or non-Class I clean operating rooms. A single operating table or two operating tables can be installed in this area; in the latter case, each operating table needs to be equipped with an air supply unit.

[0020] Specifically, the middle surgical area 5 is equipped with an operating table and necessary medical equipment, such as an ophthalmic surgical microscope and a phacoemulsification machine.

[0021] Specifically, the air supply assembly 13 installed in the static pressure box consists of a fan box 7 and a filter box 8. The fan box 7 is equipped with an EC low-noise fan, and the filter box 8 is equipped with a high-efficiency filter. The air supply assembly 13 draws in the air supply from the air outlet of the cabin air conditioning system and the air conditioning air from the front and rear cabins that seeps in through the perforated plates on the upper part of the front partition 2 and the rear partition 3. The air outlet of the air supply assembly 13 is embedded in the ceiling of the operating area and delivers clean vertical unidirectional airflow to the operating area 5 in the middle cabin.

[0022] Specifically, the upper and lower parts of the front partition 2 and the rear partition 3 are perforated wall panels, the middle part is a solid wall panel, and the middle is filled with a non-woven filter material layer. The front partition 2 and the rear partition 3 meet the Class A flame retardant requirements in GB 8624-2012 "Classification of Burning Performance of Building Materials and Products".

[0023] Specifically, the front partition 2 is equipped with the front door 9 of the operating room; the rear partition 3 is equipped with the rear door 10 of the operating room.

[0024] Specifically, the medical environment control of the front cabin, rear cabin, and operating area 5 in the middle cabin all utilizes the aircraft's air conditioning unit located on the tarmac. The air supply ducts of this unit are connected to the aircraft's dedicated external air conditioning interface. Fresh air from the air conditioning system passes through the original aircraft's air conditioning ducts, undergoes sterilization and dust removal via a high-efficiency filter, and is then delivered through the upper air outlet. The air supply assembly 13, located within the static pressure chamber of the operating area 5, draws in air from the air outlet and air from the front and rear cabins that infiltrate through the upper perforated plates of the front and rear bulkheads 2 and 3. This air is then delivered vertically clean, unidirectionally through the air outlet of the air supply assembly into the operating area, and then discharged through the lower perforated plates of the front and rear bulkheads 2 and 3. The damping effect created by the filter layer between the lower perforated plates maintains positive pressure in the operating room. Adjusting the opening of the front cabin door 11 and the rear cabin door 12 allows for smooth airflow discharge, ensuring that the pressure in the front and rear cabins is lower than that in the operating area.

[0025] Specifically, the air supply component has an air supply surface size of 1.2m x 1.2m. This ensures that the ophthalmic surgical area is protected by a sterile, dust-free, unidirectional airflow with upward supply and downward return, meeting the requirements for Class I clean operating rooms in the "Technical Specification for Clean Operating Room Buildings in Hospitals" GB 50333.

[0026] Specifically, the lower ends of the front bulkhead 2 and the rear bulkhead 3 are fixedly connected to the existing fixed guide rails on the floor of the cabin 1 via U-shaped ground grooves; the ceiling panels are fixedly connected with bolts for hanging luggage; and the side walls of the ceiling panels, the front bulkhead 2 and the rear bulkhead 3 are fixedly sealed with silicone sealant between them and the inner wall of the cabin 1.

[0027] Specifically, surgical personnel enter through the rear door 12 of the cabin, change shoes, put on caps and masks, disinfect their hands, put on sterile surgical gowns and gloves, and then enter the surgical area through the rear door 10. Patients enter through the front door 11 of the cabin for outpatient services and examinations, while patients with scheduled surgeries enter the waiting area. During surgery, they enter through the front door 9 of the surgical area.

[0028] This onboard high-level ophthalmic clean operating room includes a cabin. Inside the cabin, a front partition and a rear partition separate the front treatment area, the middle surgical area, and the rear equipment area. The upper and lower parts of the front and rear partitions are partially perforated, with non-woven fabric filter layers filling the perforated areas to form a damping layer. A ceiling panel extending through the top of the middle surgical area separates an upper plenum chamber. The plenum chamber includes air outlets for the cabin's air conditioning system and independent air supply components. The outlets of these independent air supply components are embedded in the ceiling panel, providing clean, sterile, vertical, unidirectional airflow to the middle surgical area. The independent air supply assembly contains a fan box and a filter box, without any ductwork. The fan box houses an EC low-noise fan, and the filter box contains a high-efficiency filter. Because the independent air supply assembly and the cabin air conditioning system's air outlets are located in the same upper static pressure box, the independent air supply assembly draws in air from the cabin air conditioning system's air outlets and air from the front and rear cabins that infiltrates through the perforated plates on the upper part of the front and rear bulkheads, delivering clean, vertical, unidirectional airflow to the operating area in the middle cabin. This airflow is then discharged to the front and rear cabins through the perforated plates on the lower part of the front and rear bulkheads. Due to the damping of the perforated plates, the pressure in the operating room is higher than that in the front and rear cabins, and the air conditioning airflow is forced out of the aircraft through the adjustable opening of the front and rear cabin doors. Because the front and rear bulkheads and ceiling panels are all prefabricated, and the independent air supply assembly is not connected to any ductwork, the entire component can be quickly installed and removed without causing any damage or alteration to the cabin. By overcoming existing deficiencies, this system achieves the sterile and dust-free environment control required for high-level clean ophthalmic surgery on airborne aircraft, providing high-level clean ophthalmic operating rooms for the cabins of ordinary large passenger aircraft.

[0029] This onboard high-level clean operating room for ophthalmology is particularly suitable for wide-body aircraft and can be implemented on the domestically produced C919 passenger aircraft. The C919 is a domestically developed mainline passenger aircraft with a floor height clearance of approximately 2.48m and a clearance of approximately 3.96m. Based on the C919's cabin space and internal structure design, the prefabricated bulkheads, front bulkhead 2 and rear bulkhead 3, meet the Class A flame retardant requirements of GB 8624-2012 "Classification of Burning Performance of Building Materials and Products". Front bulkhead 2 and rear bulkhead 3 are sealed to the cabin wall with silicone sealant, with a volatile organic compound content ≤100g / L. First, front bulkhead 2 and rear bulkhead 3 are installed in the middle of the cabin to form an operating room. The portions of front bulkhead 2 and rear bulkhead 3 below 0.4m and above 2m are perforated panels, filled with a non-woven fabric filter layer. A static pressure box is formed above the operating area using a suspended ceiling panel, containing the air supply vents for the cabin air conditioning system. The self-contained fan air supply assembly 13 is installed in the middle of the static pressure box. The air supply assembly meets the Class I ophthalmic clean operating room requirements of GB50333 "Technical Specification for Clean Operating Room Buildings in Hospitals" (see appendix). Figure 2The air supply unit has an outlet surface size of 1.2m x 1.2m, with a specially designed height of only 0.25m. It is equipped with an adjustable-speed EC fan. This maintains a ceiling height of 1.85m in the operating room. Since surgeries such as cataract surgery do not require shadowless lamps, the surgeon can perform the surgery while seated, meeting the surgical requirements. The air supply unit, with its built-in fan within the plenum, draws in air from the cabin air conditioning system's outlet and conditioned air infiltrating through the perforated plates on the upper part of the front and rear partitions. The air supply unit then delivers a clean, vertical laminar airflow downwards, flowing past the front of the operating table. This forms a Class I clean operating area, ensuring the temperature and humidity of the operating area. The clean airflow is then discharged to the front and rear compartments respectively through the perforated plates on the lower part of the front and rear partitions. The adjustable-speed fan ensures that the average cross-sectional velocity in the operating area is controlled between 0.15 m / s and 0.2 m / s, with a velocity non-uniformity of less than or equal to 0.24. The non-woven filter material filling the space between the perforated plates at the bottom of the bulkhead creates positive pressure in the surgical area due to its airflow damping effect. Adjusting the opening of the front and rear doors maintains the pressure difference between the surgical area and the front and rear compartments. Temperature and humidity control can be adjusted via mobile phone in communication with the ground air conditioning unit operator.

[0030] The onboard ophthalmic clean operating room is divided into a front treatment area (4), a middle operating area (5), and a rear equipment area (6) by a front partition (2) and a rear partition (3) located inside the cabin 1. An independent air supply assembly (13) with its outlet embedded in the top of the middle operating area (5) supplies clean, vertical, unidirectional airflow to this area, meeting the requirements of domestically produced passenger aircraft. Two partitions with perforated upper and lower sections create a three-compartment layout, retaining basic departments and configurations while providing corresponding clinical functions. The middle operating area meets the requirements of a high-level Class I ophthalmic clean operating room. The top partition forms a plenum above the entire operating area, housing an air supply assembly with its own fan, eliminating the need for ductwork. Air supply ducts from a dedicated ground-based air conditioning unit are connected to the aircraft's dedicated external air conditioning interface. Fresh air from the air conditioning system passes through the original aircraft's air conditioning ducts, undergoes sterilization and dust removal via existing high-efficiency filters, and is then delivered from the air supply outlets in the front cabin, rear cabin, and upper operating area. The air supply components in the operating area draw in the air from the air outlet in the static pressure box and the air conditioning air that seeps in through the upper perforated plate of the front and rear partitions before being sent downwards, which can form a vertical clean unidirectional flow in the operating area, meeting the requirements of a Class I clean operating room.

[0031] This onboard ophthalmic clean operating room integrates the hospital within the cabin of a large passenger aircraft, achieving the goal of an airborne hospital and facilitating treatment for patients from different regions. Utilizing rapidly assembled and disassembled panel walls and ductless air supply components, the entire hospital can be quickly constructed or dismantled on the aircraft. It is equipped with Class I clean operating rooms as defined in the national standard GB 50333, "Technical Specification for Clean Operating Room Construction in Hospitals." After the aircraft lands and parks on the designated apron, the onboard hospital can be rapidly constructed overnight, allowing medical services to commence the following day. After completing its designated tasks, it can be quickly dismantled without causing any damage or alteration to the cabin, meeting airworthiness requirements and allowing the aircraft to continue its flight missions.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
