[0027] 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.

[0028] A specific embodiment of the utility model is as follows Figure 1 As shown, a ventilation system for an intensive care unit is disclosed, and the intensive care unit is a cabin 1. The cabin 1 includes a front wall 101, a rear wall 102, a side wall 103 and a top 104. The top 104 is two inclined surfaces that meet at the top; the front wall 101 and the rear wall 102 are provided with passage doors.

[0029] like Figure 2 As shown, in order to ensure smooth air circulation in the ICU and reduce the virus infection rate of people in the ICU, a ventilation system is set up. The ventilation system includes an air supply port 2, an air supply pipe 3, an air distribution pipe 4, an air outlet 5 and an air return port 6.

[0030] External air is delivered to the air distribution duct 4 from the air supply duct 3 at the air supply outlet 2 of the air conditioner, and the air is delivered to the intensive care unit through the air outlet 5 on the air distribution duct 4. The air in the intensive care unit returns to the air conditioner from the return air outlet 6 on the side wall.

[0031] The air supply port 2 is arranged at the lower part of one side of the passage door of the front wall 101 and the lower part of the other side of the passage door of the rear wall 102. The air supply port 2 is provided with an air supply pipe 3.

[0032] One end of the air distribution duct 4 is connected to the air supply duct 3, and the other end is closed. Further, the air distribution duct 4 includes a first section and a second section; the first section is arranged obliquely upward, specifically, the first section and the second section form a 45° angle. The second section is in the same length direction as the cabin 1, and the first section is connected to the second section. One end of the first section is connected to the air supply duct 3, and the other end is connected to the second section. The second section is fixed to the inclined surface of the top 104.

[0033] In this embodiment, the 45° angle between the first section and the second section of the air distribution duct 4 is set to facilitate the horizontal diffusion of the airflow in the intensive care unit and the vertical settling of the airflow, thereby reducing the air stagnation area and accelerating the air circulation.

[0034] Considering the need for uniform air supply in the ward, since the second section of the air distribution duct 4 is far from the air supply port 2 and the air volume is insufficient, multiple air outlets 5 are further arranged on the air distribution duct 4, and the density of the air outlets 5 gradually increases from the beginning of the air distribution duct 4 to the end of the air distribution duct 4. The density of the air outlets 5 in the first section of the air conditioning air distribution duct 4 is set to be smaller than that in the second section, and multiple air outlets 5 are arranged in the second section; and the density of the air outlets 5 arranged at one end of the second section close to the first section is smaller than the density of the air outlets 5 arranged at the end of the second section far from the first section, so as to optimize the air flow distribution in the intensive care unit. The arrangement of the air outlets 5 in this embodiment enables the air supply of the air conditioner to form uniform air supply in the intensive care unit.

[0035] The return air inlet 6 is arranged at the lower part of the side wall 103 , and the air in the ward enters the air conditioner through the return air inlet 6 .

[0036] like Figure 3 As shown, the air supply pipe 3 is a round pipe structure. Further, in order to firmly connect the air distribution pipe 4 with the air supply pipe 3, the end portion where the air distribution pipe 4 and the air supply pipe 3 are connected is designed to be trumpet-shaped.

[0037] Specifically, the end of the air distribution pipe 4 includes a first end and a second end. The outer diameter of the first end is smaller than the inner diameter of the air supply pipe 3, and the outer diameter of the second end is larger than the inner diameter of the air supply pipe 3. A ferrule 7 is provided at the first end, and an elastic rope is provided inside the ferrule 7. When connecting the air distribution pipe 4 and the air supply pipe 3, the air supply pipe 3 is inserted from the first end of the air distribution pipe 4, and the edge of the air supply pipe 3 is the end position, which corresponds to the second end of the air distribution pipe 4, and the outer diameter of the air distribution pipe 4 corresponding to the end position is the same as the inner diameter of the air supply pipe 3. The ferrule 7 is inserted into the air supply pipe 3 and fixed with an elastic rope.

[0038] The above description is only a preferred specific implementation manner 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.
