Description

{Negative pressure simple isolation room having excellent anti-bacteria and agreeableness property}

The present invention relates to a negative pressure ward for accommodating and treating a patient, and more particularly, it can be installed quickly in an emergency situation, while inhibiting bacterial growth in the internal space of the ward in which the patient is accommodated, and preventing moisture penetration or wettability. It relates to a simple negative pressure room that can create a comfortable environment.

Recently, infectious diseases such as MERS and Corona have spread all over the world, causing many casualties. In order to treat such respiratory-related infectious diseases, negative pressure rooms are operated in which the air pressure inside the room is lower than the outside to prevent the spread of bacteria from inside the room to the outside.

However, respiratory-related infectious diseases spread rapidly from person to person in a short period of time, and there are often a shortage of negative pressure rooms due to a sudden increase in patients. .

Therefore, when an epidemic occurs, it is necessary to install a new negative pressure room in addition to the operating negative pressure room, but there is a problem in that it is difficult to quickly install a negative pressure room formed of a conventional concrete structure. In order to solve this problem, the Republic of Korea Utility Model Publication No. 20-2017-0000655 discloses a "negative pressure tent" consisting of an air tube that expands by injection of air.

However, such a negative pressure ward has the advantage of being easily installed, but there is a limit to the unique role of the ward to safely protect a large number of patients accommodated in the ward from germs, and also, due to the wall formed of an air tube, ventilation is not It is difficult to create a comfortable internal environment because it is not good.

And, as shown in FIG. 4 , the support frames 330 and 340 include a pair of horizontal support frames 330 and vertical support frames 340 facing along the edges of the fiber layers 310 and 320 . Therefore, the wall surface 300 is quickly and simply manufactured as a single panel unit by combining the horizontal and vertical support frames 330 and 340 to the edges of the fiber layers 310 and 320 cut to fit the size of the negative pressure room to be installed. can be

At this time, it is preferable that the support frames 330 and 340 have a tensile strength of 100 MPa to 400 MPa and a tensile strength of 1 GPa to 5 GPa so as not to be bent or damaged by an external impact while firmly supporting the fiber layers 310 and 320 . As a material of the support frames 330 and 340, a lightweight metal such as aluminum or a lightweight material such as fiber-reinforced plastic (CFRP), which is easy to handle while having excellent strength and rigidity, may be used.

The support frames 330 and 340 may be coupled to the fiber layers 310 and 320 using fixing means such as adhesives or fixing pieces and bolts. A reinforcing frame that crosses the surfaces of 310 and 320 may be further coupled.

The connection process of the support frames 330 and 340 is shown in FIG. 6 , and the first binding pin 350 coupled through the adjacent horizontal support frame 330 and the vertical support frame 340 and horizontally or vertically At one end of the support frames 330 and 340 , it passes through the binding hole 351 formed of the first binding pin 350 and is coupled by the second binding pin 360 orthogonal to the first binding pin 350 .

7 shows a cross-section of the fiber layer constituting the wall surface according to the present invention, wherein the fiber layer is formed by sequentially stacking a fiber base layer 311 , an antibacterial coating layer 312 , and a water repellent coating layer 313 . The fiber base layer 311 is a part constituting the skeleton of the fiber layer woven with warp and weft yarns, and the warp and weft yarns are preferably woven with a fineness of 300 to 700 denier to withstand external impact. As warp and weft yarns, not only functional fibers such as aramid fibers, ultra-high molecular weight polyethylene fibers, and carbon fibers having excellent strength, but also general synthetic fibers such as polyester or nylon fibers may be used.

The antibacterial coating layer 312 formed on the fiber base layer 311 is made of a resin mixture in which copper oxide (CuO) powder is dispersed. suppress Here, in the resin mixture, an organic solvent, a diluent and a solubilizer may be added to polytetrafluoroethylene (PTFE) or polyurethane resin having excellent water resistance and moisture permeability. Methyl ethyl ketone, acetone, diethyl ketone and methyl isobutyl ketone may be used as the organic solvent, and the diluent is one having a higher boiling point and lower surface tension than the organic solvent. Preferably, toluene, xylene, and benzene may be used. And the solubilizing agent may be dimethylformamide (dimethylformamide), dimethylacetamide (dimethylacetamide) and N-methylpyrrolidone (N-Methyl Pyrrolidone).

In addition, the copper oxide (CuO) powder dispersed in the resin mixture is preferably added in an amount of 5 to 20% by weight of the total weight of the resin mixture. If the added copper oxide (CuO) powder is less than 5% by weight of the total weight of the resin mixture, antibacterial performance is difficult to express, and if it exceeds 20% by weight, fine cracks occur during curing of the coating layer. In addition, the diameter of the copper oxide (CuO) powder to be added is preferably 1 to 10 μm, but if the copper oxide (CuO) powder diameter is less than 1 μm, it is difficult to manufacture, and if it exceeds 10 μm, the problem that the antibacterial performance is lowered have. The antibacterial coating layer thus formed is formed as a thin film having a thickness of 10 to 50 μm and is thermally bonded to the surface of the fiber base layer.

The fiber layer on which the antibacterial coating layer 312 is formed has a bacteriostatic reduction rate of 99% or more for Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352 measured by the KS K 0693 method, and the moisture permeability is KS K 0594 calcium chloride When measured by the method, it is 5,000~8,000g/m ² /24h, and the water resistance measured by the KS K ISO 811 method is 5,000~15,000 mmH ₂ O.

In addition, the water-repellent coating layer 313 is a coating layer formed to improve the water-repellent performance of the fiber base layer 311, and a fluororesin having excellent washing fastness is used, and is formed so as not to be contaminated by foreign substances on the surface of the fiber layer. Such a water-repellent coating layer 313 is formed as a thin film and laminated on the antibacterial coating layer. As such, the fiber layer on which the water repellent coating layer 313 is formed has an initial water repellency of grade 5 measured by the KS K 0590 method, and after washing 10 times by the KS K ISO 6330 (6B) method, the water repellency measured by the KS K 0590 method is 3 more than class

Therefore, as the wall surface 300 of the negative pressure hospital room exhibits excellent antibacterial performance, water resistance and moisture permeability and water repellency performance, the fiber layer exposed except for the edges where the support frames 330 and 340 are installed. It can create a safe and comfortable environment.

And, as the fiber layer is easy to cut, it can be cut to a desired size to install a negative pressure room, as well as, as shown in FIG. 1 , the independently partitioned first and second hospital rooms 110 and 120 The passage section 130 can be easily formed by cutting the fiber layer of the wall to make it easy to change the structure according to the situation.

In addition, as shown in FIG. 1 , if the fiber layer can form the window 140 by incising one side to secure visibility to the outside and adhering a transparent film, etc., it can be manufactured with fibers of various colors, so that the patient's condition The ward according to the requirements can be installed visually and easily identified.
