Claims (7)

  1. A sickroom located adjacent to the ship's cabin but independently positioned on the upper deck of the accommodation area; An isolation room located adjacent to the above-mentioned ward but separated from the ward; An air supply line for supplying air to the above-mentioned ward and isolation room; A dedicated air conditioning unit provided in the above air supply line; and A filter unit provided in the above air supply line, which sterilizes and purifies the air to be supplied to the above ward and isolation room and supplies it to the above dedicated air conditioner unit, comprising: The above filter part A pre-filter that filters out large foreign particles, including dust and pollen, from air entering from outside the vessel; and a HEPA filter that filters out small foreign particles, including fine dust and ultrafine dust, from air that has passed through the pre-filter. An air sterilization system for a ship’s infirmary, characterized in that the dedicated air conditioner unit described above further includes a plasma sterilizer that sterilizes air filtered through the pre-filter and HEPA filter, decomposes volatile organic compounds (VOCs) in the air, filters out ultrafine dust not filtered by the HEPA filter, and supplies it to the infirmary and isolation room.

  4. In claim 1, the air supply line is, A ward supply line that supplies air supplied from the above-mentioned dedicated air conditioning unit to the ward; and An isolation room supply line that supplies air supplied from the above-mentioned dedicated air conditioner unit to the above-mentioned isolation room is branched, and An air sterilization system for a ship’s ward, characterized in that the above-mentioned ward supply line and isolation room supply line are equipped with a nonreturn valve to prevent air inflow between the ward and the isolation room.
  5. In Article 1, An air exhaust line provided to draw in internal air from the above-mentioned ward and isolation room and discharge it overboard; An exhaust fan provided in the above air exhaust line; and An air sterilization system for a ship’s ward, further comprising an ultraviolet sterilizer provided upstream of the exhaust fan in the air discharge line to sterilize the air discharged from the ward and isolation room.
  6. In Paragraph 5, The air exhaust line comprises: a ward exhaust line that sucks in internal air from the ward and ward restroom and transfers it to the ultraviolet sterilizer; and an isolation room exhaust line that sucks in internal air from the isolation room and isolation room restroom and transfers it to the ultraviolet sterilizer. An air sterilization system for a ship's ward, characterized in that the above-mentioned ward discharge line and isolation room discharge line are equipped with a nonreturn valve to prevent air inflow between the ward and the isolation room.
  7. In Paragraph 5 or 6, The above-mentioned dedicated air conditioner unit is equipped with a blower fan that supplies air to the ward and isolation room through the air supply line, and An air sterilization system for a ship’s infirmary, characterized in that an amount of air greater than the flow rate of air supplied to the infirmary and isolation room through the blower fan is discharged overboard from the infirmary and isolation room through the exhaust fan, thereby maintaining the infirmary and isolation room in a negative pressure state.

Description

Air Sterilization System for Hospital Rooms on Ships The present invention relates to an air sterilization system for a ship’s infirmary, and more specifically, to an air sterilization system for a ship’s infirmary that provides a separate isolation room from a general infirmary in preparation for the occurrence of respiratory patients on board, and supplies sterilized and purified air to the infirmary and isolation room to prevent secondary infection and the spread of viruses on board. With the recent outbreak and global spread of COVID-19, the need for measures to prevent the spread of the virus through the respiratory system on ships has emerged. In particular, when a respiratory virus patient is found on board a vessel, the risk of infection among crew members is high due to the virus spreading through the cabins caused by the ship's characteristics of prolonged isolation from the outside world and living in close proximity within confined spaces. Recently, numerous cluster infection cases have occurred on warships, passenger ships, and cargo vessels in Busan, Korea, as well as in Japan and the United States, confirming that viruses spread particularly rapidly on ships. Therefore, measures are needed to prevent respiratory virus transmission on vessels. Traditionally, measures were limited to equipping onboard hospital rooms in preparation for potential medical emergencies. While most ships provide hospital rooms equipped with beds, they utilize centralized air conditioning systems shared with other cabins. Consequently, isolating patients infected with highly contagious viruses on board has been difficult; particularly in cases of respiratory illness, the air from the hospital room circulates through the ducts, posing a high risk of transmission to the crew and potentially leading to a mass outbreak. FIG. 1 schematically illustrates an air sterilization system for a ship's sickroom according to one embodiment of the present invention. In order to fully understand the operational advantages of the present invention and the objectives achieved by the implementation of the present invention, reference should be made to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described therein. The structure and operation of a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. It should be noted that in assigning reference numerals to the components of each drawing, identical components are denoted by the same numeral whenever possible, even if they are shown in different drawings. Furthermore, when it is stated that one component is 'connected,' 'supported,' 'connected,' 'supplied,' 'transmitted,' or 'contacted' with another component, it should be understood that while the connection, support, connection, supply, transmission, or contact may be direct to that other component, there may also be other components present in between. The terms used in this specification are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise, and expressions such as upper side, lower side, and side in this specification are described based on the drawings and may be expressed differently if the orientation of the object changes. FIG. 1 schematically illustrates an air sterilization system for a ship's sickroom according to one embodiment of the present invention. As illustrated in FIG. 1, in the ship of this embodiment, a ward (H) capable of accommodating general patients and an isolation room (I) capable of accommodating patients with infectious viruses or those with suspected symptoms are provided separately from the general cabins, and air is supplied to the ward and isolation room through a dedicated air conditioning unit (100) to maintain a negative pressure state so as to prevent the spread of viruses within the ship. As shown in FIG. 1, a ward (H) for general patients and an isolation room (I) for patients with infectious diseases are independently placed on the upper deck of the accommodation area so as to be adjacent to the general cabins of the ship while being separated from the general crew. Beds and various furniture are arranged within the patient room (H) and isolation room (I) so that the patient or isolated person can reside independently, and a hatch is installed on the door to allow food or supplies to be delivered into the patient room (H) or isolation room (I). Additionally, a private toilet (Ht, It) may be installed inside the patient room (H) and isolation room (I). In the case of individuals who need to be isolated from general crew members and general patients, such as those who have had close contact with a confirmed patient or have boarded in an area at risk of virus infection, they may be isolated in an isolation room (I) for about 14 days.
