[0002] A laminar flow ward is a ward that maintains sterility indoors through air purification equipment and is equipped with equipment to change the cleanliness of the air environment. To maintain sterility indoors, the environment and air are disinfected daily, and items entering the laminar flow room need to be sterilized. There are also corresponding regulations for entering the room. When a patient undergoes hematopoietic stem cell transplantation, before the reconstruction of hematopoietic and immune functions, due to high-dose chemotherapy and radiotherapy, almost all of the patient's hematopoietic function and immune defense system are destroyed, and the patient is in a severe immunodeficiency state with pancytopenia, bone marrow failure, and is extremely prone to various infections and other complications. Various pathogenic infections are the most common complications in hematopoietic stem cell transplantation and one of the main causes of death in hematopoietic stem cell transplantation. According to this particularity, the patient needs to be protected and isolated in a full environment, that is, in a dedicated hematopoietic stem cell transplantation ward - also known as a sterile air laminar flow ward.

[0040] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the premise that those of ordinary skill in the art can implement them. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0041] Currently, most existing laminar flow wards are installed on the ground. Due to limited hospital resources, there are few areas where laminar flow wards can be installed. When more laminar flow wards are needed, other medical areas will be occupied, reducing the overall space utilization rate of the hospital, restricting the planning of other functional areas, disrupting the layout, increasing the management difficulty, and the re-planning consumes costs and interferes with the operation. This leads to a shortage of hospital land, affecting medical work. It makes it difficult to place other medical equipment, compresses the working space of medical staff, and deteriorates the medical environment for patients. For the limited number of laminar flow wards, it may also delay the treatment of patients in urgent need of a special treatment environment, which is not conducive to recovery.

[0042] See Figures 1 to 7As shown in the figure, in order to effectively improve the overall space utilization rate of the hospital, increase the number of laminar flow ward arrangements, and facilitate the use by more patients in need, this embodiment provides a laminar flow ward, which includes a ward main body composed of a plasma air disinfection machine 1, a laminar flow clean hood 2, a hood 3, and an electrical control box 11. The laminar flow clean hood 2 and the plasma air disinfection machine 1 are interconnected through the electrical control box, and the data collected in the laminar flow clean hood 2 can be transmitted to the plasma air disinfection machine 1 in a timely manner through the electrical control box. Through this data transmission, the plasma air disinfection machine 1 can realize the function of intelligent air volume adjustment.

[0043] See Figure 1 and Figure 2 As shown in the figure, a plasma air disinfection machine 1 is provided on one side of the laminar flow clean hood 2. The plasma air disinfection machine 1 is connected to one of the air inlets 10 on the laminar flow clean hood 2 through a special-shaped air duct 4. A 0.3 mm thick PEVA transparent soft curtain 8 is provided around the laminar flow clean hood 2. A hood 3 is installed on the upper side of the laminar flow clean hood 2 to seal the upper side of the laminar flow clean hood 2. Both the laminar flow clean hood 2 and the hood 3 are rectangularly arranged. Furthermore, support columns 7, flipping units 5, hanging parts 12, and hanging and connecting parts 13 with the same structure are respectively provided at the four corners of the hood 3. Specifically as follows:

[0044] Multiple support columns 7 are respectively arranged at each corner on the periphery of the hood 3. A flipping unit 5 is provided between each support column 7 and the hood, and the flipping unit 5 can be used to realize the state conversion of the support column 7 between 0° and 180°; the hanging part 12 is connected to the end of the support column 7 away from the flipping unit 5; the hanging and connecting part 13 is detachably connected to the hanging part 12, and the hanging and connecting part 13 is used to connect to the roof of the hospital ward; specifically, when the support column 7 is at 0°, at this time the hanging part 12 and the hanging and connecting part 13 are in a separated state, and the support column 7 is positioned and leaned against one side of the ward main body through the flipping unit 5. At this time, the ward main body can be placed in direct contact with the ground through the laminar flow clean hood 2 to realize the floor installation of the ward main body; when the support column 7 is at 180°, at this time the support column 7 is flipped and positioned on the top of the ward main body through the flipping unit 5. At this time, through the connection and fixation of the hanging part 12 and the hanging and connecting part 13, the laminar flow clean hood 2 is separated from the ground by a certain distance to realize the suspension installation of the ward main body.

[0045] See Figures 1 to 5As shown in the figure, the flipping unit 5 includes a rotating rod 51 and a snap spring 52. The rotating rod 51 is inserted through the side walls of the support column 7 and the cover 3, and the rotating rod 51 is rotatably connected to the support column 7; the snap spring 52 is installed between the rotating rod 51 and the cover 3, its fixed end is fixedly connected to the cover 3, and the movable end is clamped on the support column 7. Through the limiting cooperation of the snap spring 52, the fixation of the cover 3 and the rotating rod 51 can be realized, and then the rotational connection relationship between the support column 7 and the cover 3 can be used during use to realize the rotation of the support column 7 along the vertical direction on one side of the cover 3; furthermore, in order to ensure that the support column 7 can be positioned with the cover 3 after rotating to an appropriate angle, at least one fixing unit 6 is provided between the cover 3 and the support column 7. In practical applications, it is recommended to use two fixing units 6 for one support column 7 and the cover 3. The fixing unit 6 includes a pull rod 61 and an elastic limiting part. The pull rod 61 is inserted through the support column 7, and the pull rod 61 passes through the support column 7 for cooperation with the through hole on the cover 3. The elastic limiting part is arranged between the pull rod 61 and the support column 7 to realize the insertion and separation of the pull rod 61 and the through hole. In addition, in order to facilitate the movement of the laminar flow ward after it is placed on the ground and realize the layout on the ground, a plug-in part is connected to the end of the support column 7 far away from the cover 3 by bolts, and a universal wheel 9 is also provided at the end of the plug-in part far away from the support column 7.

[0046] See Figure 7 As shown in the figure, further, in order to realize the fixation and separation adjustment of the support column 7 and the cover 3. The elastic component includes a spring 62, a limiting plate 64 and a fixing frame 65. The spring 62 is sleeved on the pull rod 61; the limiting plate 64 is arranged between the spring 62 and the support column 7. The limiting plate 64 is sleeved and fixed on the pull rod 61, and one end of the spring 62 abuts against the limiting plate 64; the fixing frame 65 is sleeved on the outside of the spring 62. One end facing the limiting plate 64 is open and fixedly connected to the support column 7, and the other end is closed and sleeved on the pull rod 61. The other end of the spring 62 is placed inside the fixing frame 65 and fixedly connected to the side wall of the fixing frame 65 away from the limiting plate 64. In addition, in order to ensure stable positioning, a limiting groove is opened on the support column 7. The limiting plate 64 is placed in the limiting groove, and the limiting plate 64 is slidably connected to the side wall of the limiting groove. Furthermore, in order to facilitate the operation of the pull rod 61, a pull cap 63 is fixedly connected to the end of the pull rod 61 far away from the cover 3.

[0047] See Figure 5 and Figure 6As shown in the figure, the suspension part 12 is used to connect with one end of the support column 7 away from the cover 3, and the hanging part 13 is used to be installed on the roof of the ward. The suspension part 12 and the hanging part 13 are detachably connected. Specifically, the suspension part 12 includes a fixed beam 122 and a connecting bolt 121. The fixed beam 122 is connected with one end of the support column 7 away from the cover 3 through the connecting bolt 121. A connecting groove for connecting with the hanging part 13 is arranged on the suspension beam. The hanging part 13 includes a suspension rod 131 and a locking nut 132. The upper end of the suspension rod 131 is fixed to the roof of the ward, and the lower end is clamped in the connecting groove and connected with the fixed beam 122 through the locking nut 132. In practical application, when the support column 7 rotates to the top of the cover 3 and is in the 180-degree state, at this time, the support column 7 and the cover 3 should be kept perpendicular, and then the suspension installation of the laminar flow ward is realized through the connection of the suspension part 12 and the hanging part 13; when the support column 7 rotates to the bottom of the cover 3 and is at 0 degrees, at this time, the support column 7 and the cover 3 are still in a perpendicular state, and the laminar flow ward can be installed on the ground.

[0048] In addition, in order to make the space utilization rate wider after suspension, the support column 7 is telescopically arranged. Preferably, an electric telescopic rod is arranged between the support column 7 and the fixed beam 122. The fixed end of the electric telescopic rod is fixed to the support column 7, and the telescopic end of the electric telescopic rod is detachably connected with the fixed beam 122, so that the height can be increased and changed during suspension, making the space at the bottom larger. At the same time, the lifting operation is convenient through the electric control of the electric telescopic rod, and the application is more convenient.

[0049] Thus, through the cooperation of the above-mentioned parts, the installation and use method of the laminar flow ward is as follows:

[0050] When the laminar flow ward is laid out on the ground, the laminar flow ward is pushed to the installation location through the universal wheels 9, and the locking mechanism on each universal wheel 9 is adjusted to realize braking, so that the laminar flow ward is fixed and balanced on the ground. Then, the air inlet 10 on the corresponding side is opened, and the seamless docking between the plasma air sterilizer 1 and the laminar flow clean hood 2 is completed to realize the direct application of the laminar flow ward on the ground.

[0051] When the installation space on the ground is limited and more laminar flow wards need to be installed for the use of more patients, according to the actual situation of the room, the plug-in parts on the support column 7 are removed, so that the plug-in part is separated from the support column 7. The pull caps 63 on both sides of the top of the support column 7 are pulled up, and the spring 62 is compressed under force, so that the pull rod 61 is separated from the through hole on the cover 3. The support column 7 is rotated clockwise by 180 degrees to the top of the cover 3, that is, at this time the support column 7 is vertically placed above the laminar flow clean hood 2. The pull cap 63 is pressed, so that the pull rod 61 is inserted into the through hole of the laminar flow clean hood 2, and then the support column 7 is fixed to the fixed beam 122 through the connecting bolt 121, and is fixed to the connecting groove on the fixed beam 122 through screw connection by the hanging rod 131, so that the main body of the ward is suspended on the roof of the ward in cooperation with the support column 7, the fixed beam 122 and the hanging rod 131, realizing the suspended installation. At the same time, the plasma air disinfection machine 1 is started, and the purified air is conveyed into the laminar flow clean hood 2 through the special-shaped air duct 4. The surrounding structure formed by a plurality of transparent PEVA soft curtains can reduce the entry of external air and avoid cross-infection. Preferably, in actual application, the overall size structure of the laminar flow clean hood 2 can be selected as 2355mm*1800mm*2050mm. The air replacement rate can be adjusted between 150-280 times / h by using the plasma air disinfection machine 1, and the dynamic hundred-level laminar flow sterile clean level is maintained, and finally all the work of the plasma mobile hematopoietic stem cell transplantation cabin is completed.

[0052] Obviously, those skilled in the art can make various changes and deformations to the present utility model without departing from the spirit and scope of the present utility model.
