Problems solved by technology

The existing common prefabricated steel structure wards are built quickly, but the air / water sealing performance is poor, the heat insulation and sound insulation performance is not good, and they cannot be used for a long time, so it is difficult to reserve in advance
In 2011, Tian Feng and others invented and disclosed an inflatable mobile isolation room CN102225032 for on-site treatment of infectious disease patients. Although it can quickly form a temporary treatment space during an epidemic, the airtightness and structural safety, stability, and durability gender needs to be improved
In 2019, Liang Huiwei proposed a negative pressure isolation ward for infectious diseases CN109424220A. This ward is independently built and has good sound insulation effect, but the construction speed is slow and the air / water tightness is poor. It is difficult to be in place in time during the outbreak period. effective service

Embodiment Construction

[0043] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0044] figure 1 It is a schematic structural diagram of the 3D printing negative pressure medical cabin in the embodiment. 3D printing can realize the construction of negative pressure medical cabins with various complex shapes. According to the topology optimization analysis under the combined working conditions of medical negative pressure, structural weight, equipment load and patient load, the medical negative pressure of the annular capsule cabin type is preferred in this embodiment. cabin, but is not limited to this form. This form of medical cabin has the advantages of reasonable force, smooth space, easy disinfectio...

Abstract

The invention discloses an 3D-printed negative pressure isolation ward establishing method based on topology optimization. According to medical requirements and use working conditions, the computer topology optimization technology is adopted to conduct space optimization design, and the optimal space shape is determined; according to medical equipment and a conventional treatment method, an instrument cabin window and a medical treatment cabin window are designed and reserved; according to the storage and transportation standards, the service cycle and the work condition of the medical equipment, printing building materials are selected; a printing path and machining steps are designed; and according to the thickness and hoisting points of the building materials, the 3D printing technologyis adopted to print the negative pressure isolation ward through layered printing or integrated printing or segmented printing according to the preset structure space shape. The 3D-printed negative pressure isolation ward establishing method based on topology optimization can form a continuous airtight medical treatment space which is reasonable in space stress and in a special structure shape. The established 3D-printed negative pressure isolation ward has the advantages of being rapid in establishing speed, good in use performance, high in mechanical degree, convenient to transport and capable of being spliced and combined and meeting the anti-epidemic treatment demand under the infectious respiratory tract epidemics.

Description

technical field [0001] The invention belongs to the technical fields of building materials, building structures, building construction, building design, etc., and in particular relates to a construction method of a 3D printing negative pressure medical cabin based on topology optimization. Background technique [0002] Influenza viruses and coronaviruses are ubiquitous in nature and coexist with human society for a long time. They have the characteristics of strong variability, strong seasonality, fast infectivity, and wide spread. With economic development, these viruses have induced large-scale respiratory infections in recent years. Infectious epidemics lead to frequent occurrence of global events. The treatment environment and rapid allocation of medical resources for critically ill patients in respiratory epidemics have become the most critical technical links in such epidemics, which pose a high challenge to modern medical science, construction technology and managemen...
