DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] The utility model discloses an air film ward, such as Figure 1 As shown, the ward includes an air membrane 1.

[0037] Air film 1 is TPU brushed film, which has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance, light weight, non-toxicity, corrosion resistance, radiation resistance, etc., flame retardancy B1 level, pressure resistance>15Psi, unit weight ≤2000g / m 2 The working temperature is -50℃~+60℃, and it can construct an air membrane structure with high structural stability, strong load supporting capacity, good thermal insulation, vibration absorption and load adaptability.

[0038] After being inflated, the air membrane 1 covers the upper part of the floor 2 , serving as the front wall 101 , the rear wall 102 , the side wall 103 and the top 104 of the intensive care unit.

[0039] like Figure 2 and Figure 3As shown, the front wall 101 and the rear wall 102 are plane walls. According to the shape of the intensive care unit, the top is configured to be a pointed roof with an opening in the middle, which is the passage door 4.

[0040] An air-conditioning air supply vent 5 is arranged at one side of the passage door 4, and a square Oxford perforated cloth is glued at the air-conditioning air supply vent 5, and an Oxford cloth cover is sleeved thereon to seal the air supply duct.

[0041] The front wall 101 is provided with a rainproof curtain 6 for connecting with the passage shed.

[0042] A side wall 103 and a top 104 are arranged between the front wall 101 and the rear wall 102. The top 104 includes two slopes, which meet at the top to form a herringbone structure; the side wall 103 is a vertical structure. The top 104 and the connection between the side wall 103 and the top 104 are formed by bending the air film 1.

[0043] The side walls (103) and the top (104) are provided with edging strips at their end faces. Specifically, the edging strips have a width of 20 cm. Furthermore, Velcro strips are provided on the edging strips. When the front wall (101) and the rear wall (102) are connected to the side walls (103) and the top (104), the edging strips and Velcro strips are used for fixing.

[0044] Four windows 7 are arranged on both sides of the side wall 103. The structure of the window 7 is that a hole is directly opened on the side wall 103, and then the edge of the air film 1 is welded. To prevent rainwater from entering through the window 7, curtains are arranged on the inside and outside of the window 7.

[0045] A plurality of gas charging and discharging interfaces 103 are provided on the front wall 101 , the rear wall 102 and the side wall 103 at a height of 20 cm from the ground for charging and discharging the air membrane 1 .

[0046] The air membrane 1 comprises an inner membrane surface 11, an outer membrane surface 12 and an intermediate core layer 13, and the intermediate core layer 13 is a wire drawing sandwich.

[0047] The air film 1 is a double-layer airbag structure, with a 20 cm inflatable interlayer inside the inner and outer film surfaces, which can form a flat component after being inflated. The air film 1 can be bent and inflated to form a bent component.

[0048] When the air film 1 needs to be bent, Figure 5 and Figure 6 As shown, the inner membrane surface 11 is provided with a slit 111. After the slit 111 is provided, the inner membrane surface 11 includes a first butt joint surface and a second butt joint surface. The first butt joint surface and the second butt joint surface are respectively arranged on both sides of the slit 111. The first butt joint surface and the second butt joint surface are welded and connected. The angle between the first butt joint surface and the second butt joint surface is a bending angle.

[0049] The calculation formula of the width of the slit 111 is:

[0050] L=αh

[0051] Wherein, α is the bending angle, in radians; h is the wire drawing height of the intermediate core layer 13, in mm; and L is the width of the slit 111, in mm. According to the mechanical properties and processing requirements of the air film 1, the predetermined bending angle can be achieved by opening the air film 1 multiple times in succession.

[0052] The air membrane 1 in this embodiment can be a flat membrane surface or bendable, and can be used for structures such as roofs. Compared with the complex structures in the prior art, in this embodiment, the cutting width of the slit 111 is calculated according to the preset bending angle and drawing height, and the inner membrane surface 11 is cut and then welded into a new inner membrane surface 11. It can be used for any bending angle. Compared with the prior art where the bending of the air membrane 1 is achieved by trial and error, the trial and error cycle is shortened and the trial and error cost is reduced.

[0053] In the air-film ward, the air film 1 is directly placed on the floor 2 and is fixed by the gravity of the air film 1 itself.

[0054] When inflating, connect the inflation pump interface with the inflation and deflation interface 3 of the air film 1, start the inflation pump, and inflate in the order of front to back, back to left and right, until the air film 1 is fully deployed; when deflation, connect the vacuum pump interface with the inflation and deflation interface 3, start the vacuum pump, and deflate in the order of first left to right, then front to back, until the air film 1 collapses.

[0055] In this embodiment, the air membrane 1 is inflated to form the main structure of the ward cabin, and the air membrane 1 is directly folded after being deflated. The ward can be quickly expanded and folded through a simple inflation and deflation method, which is convenient for rapid and efficient treatment of patients.

[0056] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
