Description

Technical Field

[0001] The invention belongs to the field of modular mobile hospitals, and in particular relates to a disinfection and sterilization modular hospital. Background Art

[0002] When an infectious disease breaks out, it is difficult to quickly and promptly establish a safe and reliable isolation hospital for effective treatment of patients. In view of this situation, the establishment of a mobile infectious disease hospital system is an inevitable trend. Mobile hospitals built with shelters or containers as the main carrier form can be transported by vehicles and deployed quickly, becoming the first choice to solve this problem.

[0003] In traditional mobile hospitals, the disinfection and sterilization supply center is an important department for disinfection and sterilization operations and the supply of sterile equipment and materials in mobile hospitals. It has become the top priority of infection control in mobile infectious disease hospitals and is related to the infection control safety of the entire hospital. In order to avoid cross-infection in hospitals to the greatest extent, the National Health and Family Planning Commission has formulated the WS310.1-2016 "Hospital Disinfection and Sterilization Supply Center" management specification, which puts forward physical divisions such as decontamination areas and clean areas for hospital disinfection and sterilization supply centers (CSSD), and the requirements for directional flow of airflow and material flow in different areas.

[0004] Due to the flexibility of its design and construction, fixed hospitals are easy to follow the management specifications of "Hospital Disinfection and Sterilization Supply Center" and realize the requirements of physical partitioning and directional flow of personnel and materials. However, for mobile hospital disinfection and sterilization supply centers based on the form of cabin technology, due to the extremely limited space in the cabin, the upper equipment includes fabric disinfection, cleaning, drying, steam sterilization, low-temperature sterilization, water supply, packaging, environmental control equipment, etc., and the safety of vehicle transportation center of mass, axle load, etc., its design and construction are complex. At present, no disinfection and sterilization cabins have been found for mobile hospital systems that can realize the physical partition of decontamination areas and clean areas, and the directional flow of airflow and personnel flow in different areas. Most of them share decontamination and sterilization space, and there is no positive and negative pressure design. Material flow and airflow cannot achieve directional flow, which does not meet the relevant standards of the National Health and Family Planning Commission. Cross-contamination is easy to form during disinfection and sterilization operations, posing a threat to the infection control safety of mobile hospital systems. Summary of the invention

[0055] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0056] The present invention provides a disinfection and sterilization cabin, which is mainly used for washing, drying and sterilizing surgical instruments, surgical clothing sheets, endoscopes, catheters, etc. in a cabin-type rapid deployment hospital system. The disinfection and sterilization cabin can be used alone or combined with other cabins, tents, etc., and can be quickly deployed to become a hospital disinfection and sterilization supply center under the infectious disease mode. This combination can be deployed according to actual needs to meet the requirements of different hospitals.

[0057] Specifically, Figure 1As shown, the disinfection and sterilization cabin includes a fixed cabin 1 and an expansion cabin 2; the fixed cabin 1 includes a decontamination area 11 and a first clean room 12; the expansion cabin 2 can be folded into the fixed cabin 1. The cabin designed by the present invention uses a 6m single-expansion cabin, and the single-side expansion size (length × width) is ≥4000mm×1600mm. After expansion, it is divided into three parts: a decontamination area 11, a clean area and a buffer zone 21. The expansion cabin 2 includes a buffer zone 21 and a second clean room 22; the first clean room 12 and the second clean room 22 constitute a clean area, and there is no partition between the first clean room 12 and the second clean room 22; when the cabin is unfolded, the decontamination area 11, the buffer zone 21 and the clean area form a physical isolation. When connected to other hospital modules, the clean area and the decontamination area 11 are respectively connected to the medical staff passage and the patient passage. The decontamination area 11 is provided with a negative pressure device, and the negative pressure difference between the decontamination area 11 and the external environment is greater than or equal to 5 Pa; the clean area is provided with a positive pressure device, and the positive pressure difference between the clean area and the external environment is greater than or equal to 5 Pa. The buffer zone 21 is not provided with a positive pressure device or a negative pressure device, and its internal air pressure is the pressure difference between the clean zone and the decontamination area 11. Due to air leakage, the buffer zone 21 naturally forms a negative pressure.

[0058] Preferably, the maximum pressure difference between the decontamination area 11 and the clean area can be 30Pa (negative 20Pa in the decontamination area and positive 10Pa in the clean area), realizing the one-way flow of the airflow in the disinfection and sterilization cabin. After connection, a pressure difference of not less than 5Pa can be established between the disinfection and sterilization cabin and the medical staff channel, and a pressure gradient of not less than 5Pa is also achieved between the three areas inside the cabin, which minimizes the possibility of cross infection in the disinfection and sterilization cabin.

[0059] A pressure difference regulating device is also provided between the decontamination area 11 and the clean area; the pressure difference regulating device can be opened or closed; the pressure difference regulating device can also be set to different openings. By adjusting the opening of the pressure difference regulating device, the air pressure difference between the decontamination area 11 and the clean area can be adjusted to form a directional airflow from the clean area to the decontamination area.

[0060] Preferably, the pressure difference regulating device is a shutter. A shutter is also provided between the decontamination area 11 and the clean area, and the shutter opening can be adjusted. By adjusting the shutter opening, the air pressure difference between the decontamination area 11 and the clean area can be adjusted.

[0061] The three zones are isolated by pressure difference. The gas in the cabin flows in one direction. Figure 6 As shown, on the one hand, the air flow can flow directly from the clean area to the decontamination area 11 through the pressure difference regulating device, such as Figure 6 Direct airflow direction 62 shown by arrow ( Figure 6In the figure, the direct airflow direction 62 only indicates that the airflow flows from the clean area to the decontamination area 11 through the pressure difference regulating device, and does not mean that the pressure difference regulating device can only be set at the position where the direct airflow direction 62 passes; the pressure difference regulating device can be set at a suitable location at the junction of the clean area and the decontamination area 11 as needed). On the other hand, the airflow can flow from the clean area to the buffer zone 21, and finally to the decontamination area 11, as shown in the arrow direction of the indirect airflow direction 63; and the logistics enters from the buffer zone 21, passes through the decontamination area 11, and finally reaches the clean area. When the material transfer window 37 is opened, it is stipulated that the sterilized materials can only be transferred from the decontamination area to the clean area in one direction, and then packaged and sterilized, or other operations are performed, as shown in the arrow direction of the logistics direction 61. At this time, the airflow also flows from the clean area to the decontamination area 11 in one direction through the opened material transfer window 37.

[0062] The air guides of the HVAC in the decontamination area 11 and the clean area are also isolated. The disinfection and sterilization cabin is equipped with a first hot air device and a second hot air device for heating in winter; the first hot air device is used to provide hot air to the decontamination area 11; the second hot air device is used to provide hot air to the clean area; the first hot air device and the second hot air device are designed for independent hot air supply and return.

Figure 2As shown, the dotted parts in the figure are the air outlet duct and the air return duct respectively, the air outlet duct is close to the expansion cabin 2, and the air return duct is far away from the expansion cabin 2. The second hot air duct return air port 121 is arranged at the first side of the first clean room 12, and the second hot air duct return air port 121 is far away from the expansion cabin 2; the second hot air duct air outlet 122 is in the middle of the clean area, close to the junction of the decontamination area 11 and the first clean room 12, and the second hot air duct air outlet 122 is close to the first hot air outlet 112.

[0065] The design of HVAC in the cabin is based on ergonomic design and follows the principle of maximizing space utilization. At the same time, the air outlets and return air outlets of the decontamination area 11 and the clean area are as far away as possible in the area, and sufficient circulation of internal hot air is ensured.

[0066] Preferably, the decontamination area 11 and the clean area are also equipped with independent air conditioners.
