Positive and negative pressure conversion movable sickbed

Abstract

The invention belongs to the technical field of indoor air environment purification, and particularly relates to a positive and negative pressure conversion movable sickbed, which consists of a sickbed, an air purification device, a fan, an air distribution pipeline system, an electric control valve system and an isolation system, wherein four bed legs of the sick bed are provided with wheels, the sickbed can be used as a moving sickbed or a fixed sickbed, the sickbed can realize the positive pressure air supply and negative pressure air suction functions, air distribution openings of an air distribution system are arranged on the head part of the sickbed and the tail part of the sickbed, the air distribution pipeline system is paved along the bottom of a bed plate and is connected with the air purification device through the electric control valve, the control system controls the fan to do positive rotation, the positive pressure air supply can be realized, clean air is provided for patients with the requirements, the fan is controlled to do reverse rotation, the negative pressure air suction can be realized, air with pathogenic bacteria breathed out by patients are collected in time, and in addition, the air is exhausted after the sterilization and the purification. The positive and negative pressure conversion movable sickbed has the advantages that the design structure is compact, other functions such as sickbed ascending and descending and the like cannot be influenced, the noise pollution is avoided, the energy consumption is low, the dust removal, sterilization and purification effects are obvious, and the positive and negative pressure conversion movable sickbed is suitable for being used as an ordinary sickbed or emergency sickbed for patients to be isolated in occasions such as hospitals and the like.

Description

technical field [0001] The invention belongs to the technical field of purification of indoor air environment, and in particular relates to a movable hospital bed capable of providing clean air for patients and absorbing and purifying the air exhaled by patients. Background technique [0002] IAQ is the English abbreviation of Indoor Air Quality. With the continuous improvement of life and technology, people have higher and higher requirements for indoor air quality, especially for hospitals that have high requirements for indoor air quality. But the indoor air quality is quite fragile in public places. Due to the entry of patients with various diseases, especially those with respiratory diseases and infectious diseases, different types of germs and viruses have been bred in the air environment of the hospital and spread with the flow of air, especially SARS, which has spread widely. Viruses such as pneumonia are extremely contagious and vital. Patients with infectious dise...

AI Technical Summary

Problems solved by technology

In addition, for some patients who are susceptible to bacterial infection due to trauma or whose respiratory system is particularly sensitive, it is necessary to provide clean air for patients who have high requirements for inhaled air, but often the air environment in hospitals cannot meet the requirements of such patients.

[0003] At present, all major hospitals have isolation wards, and isolation measures are taken for some patients with infectious diseases. Although the isolation effect of such wards is very good, the construction requirements and investment costs are also high, and the number of isolation wards is limited. And because of the isolation between patients and non-patients, medical staff must wear protective clothing, masks, gloves, etc. during inspections or treatment, which is very inconvenient; therefore, isolation wards in hospitals can only be provided for patients with severe Patients with infectious diseases, for other ordinary patients, and ordinary patients with infectious diseases such as respiratory diseases, are mostly arranged in ordinary wards. Without strict disinfection and sterilization and other protective measures, this situation often causes different infections. Cross-infection of diseases, or other non-patient diseases

Major hospitals take measures such as isolation for a small number of patients with infectious diseases such as respiratory diseases, but respiratory diseases often have high incidence periods due to climate or seasonal effects. It is difficult to meet the requirements, and the sterilization effect only by spraying disinfectant indoors is limited, so that the staff in the hospital or the family members of patients are extremely vulnerable to infection and disease

In addition, under normal circumstances, hospitals often provide separate wards or wards with special air quality treatment for patients who are susceptible to trauma or have high air quality requirements, which greatly increases the cost of medical treatment for patients, etc.
