Description

Mobile negative pressure chamber {MOBILE NEGATIVE PRESSURE CHAMBER}

The present disclosure relates to a movable negative pressure chamber, and more particularly, to a movable negative pressure chamber capable of installing a monitoring device for monitoring a patient located inside the movable negative pressure chamber.

As movement between countries becomes commonplace in modern society, the spread of contagious viruses has become an unavoidable international social problem. The possibility of a virus originating on the other side of the globe entering the country is also increasing.

Isolation of carriers of the virus is essential to prevent the spread of a virus that has already begun to spread. For example, since the COVID-19 virus is very contagious, patients who test positive are transferred to an isolated facility with the help of medical personnel.

A negative pressure hospital room installed in a medical institution is a space in which viruses, aerosols, pathogens, and the like inside the room are prevented from leaking outside without permission by maintaining the air pressure in the room lower than the outside air pressure. The air in the hospital room is purified through a sterilization and filtering process and then exhausted.

A mobile negative pressure chamber is used during the process of transferring a virus-infected patient to a negative pressure room. A conventional mobile negative pressure chamber is a kind of bag made of waterproof fabric and provides an airtight space in which a patient can lie down. The patient is transported to a medical institution on a cart while lying in a negative pressure chamber.

At one side of the negative pressure chamber, a negative pressure device is installed to keep the pressure inside the negative pressure chamber lower than atmospheric pressure. The negative pressure machine sucks in the air inside the negative pressure chamber, filters it, and discharges it to the atmosphere. Also, an oxygen cylinder is used to supply oxygen into the negative pressure chamber. Medical personnel hang the oxygen bottle on a cart, connect a hose between the oxygen bottle and the negative pressure chamber, and then open the valve of the oxygen bottle to supply oxygen to the negative pressure chamber.

Existing negative pressure chambers have a bag-shaped structure, which makes it impossible to install a monitoring device for monitoring a patient located inside because of poor durability. Furthermore, in the case of a bag-shaped structure, the inner chamber is not well sealed, and it is not easy to install a port on the side.

The upper cover 120 constitutes an upper structure of the movable negative pressure chamber 100, and the lower cradle 140 constitutes a lower structure of the movable negative pressure chamber 100, and is transported to the space provided by the lower cradle 140. Patients can be accommodated. In addition, the upper cover 120 may be combined with the lower holder 140 to form a sealed inner space.

The upper cover 120 and the lower holder 140 are not made of a flexible material such as cloth or vinyl, but are formed in a hard shell type, so that the inner space can be stably maintained in a sealed state even against impact or movement. Such a hard shell type has the advantage of allowing an additional monitoring device to be mounted on the movable negative pressure chamber 100 .

For example, an adult can be accommodated in the inner space provided by the upper cover 120 and the lower holder 140 . The length of the movable negative pressure chamber 100 in which the upper cover 120 and the lower holder 140 are combined may correspond to approximately 2000 mm to 2500 mm so as to be easily transported through an ambulance. The width of the movable negative pressure chamber 100 may correspond to approximately 500 mm to 750 mm, and the height may correspond to approximately 500 mm to 750 mm. The movable negative pressure chamber 100 may accommodate up to 180 cm and 120 kg of patients.

The upper cover 120 and the lower holder 140 may be made of a material that is rigid, non-combustible, and lightweight. If the movable negative pressure chamber 100 is formed of a rigid material, it may be advantageous to clean or disinfect an internal space in which a patient with a highly contagious disease is accommodated. Furthermore, the rigid material enables the patient monitoring device to be installed outside the movable negative pressure chamber 100 .

Part or all of the upper cover 120 may be made of a transparent material, such as polycarbonate. The transparent rigid upper cover 120 may provide a field of view through which a patient accommodated in the internal space can see the outside or an external paramedic or medical staff can see the patient accommodated in the internal space. The transparent rigid upper cover 120 can relieve the patient's fear of being in a closed space, enable communication while transporting the patient, and enable immediate response to changes in the patient's condition. Furthermore, the transparent rigid upper cover 120 enables a monitoring device installed on the outer upper portion of the upper cover 120 to monitor a patient accommodated inside the upper cover 120 .

The upper cover 120 may be composed of an upper surface facing the bottom surface of the lower holder 140 and a side surface extending downward from the upper surface. The side of the upper cover 120 has a curved surface, and may lead to a curved shape of the upper and side surfaces of the upper cover 120 . Using this structure, the monitoring device can be easily installed on the upper cover 120 .

The lower holder 140 may be made of a material such as aluminum, carbon fiber, or plastic. The lower cradle 140 may provide a space for a patient to lie down and may have an assemblable structure. For example, the lower holder 140 may be assembled by combining three parts.

The lower surface of the lower holder 140 may be formed flat so that the movable negative pressure chamber 100 can be stably placed on the floor. The lower holder 140 may have a side surface extending upward from a bottom surface. If the side of the lower holder 140 in the longitudinal direction is lower than the other parts, it is possible for the patient to enter or exit the lower holder 140 easily.
