Description

WHEELCHAIR WITH MANAGING SANITATION SYSTEM [0001]

The present invention relates to a wheelchair for assisting movement of a patient having an uncomfortable movement, and more particularly, to a wheelchair for supporting the movement of a patient who is uncomfortable to move, and more particularly, for a patient who is seated on a wheelchair for a long period of time, The present invention relates to a wheelchair provided with an integrated sanitary management system capable of checking the seat replacement period, notifying the manager, and collecting biometric information of the patient to perform health management.

Generally, wheelchairs are provided for patients who are uncomfortable in hospitals or rehabilitation centers. Since the wheelchair is used by various patients, it is contaminated with various germs and pathogens and functions as a mediator of secondary infections that cause infection in hospitals, so that patients are more likely to suffer other diseases.

In general, healthy human hands have latent bacteria of 200,000 / ㎠ to 300,000 / cm3, and when hand washing and sterilization are neglected, the number of bacteria detected is about 5 million / ㎠ ~ 3200 / ㎠ Colonies and Escherichia coli are irradiated in excess of 3500 / ㎠ to 1100 / ㎠. In severe cases, ticks, fungi and ticks are found, and various bacteria floating in the air including contact bacteria and pathogens ) And pathogens are submerged and parasitic in wheelchairs, causing secondary infections in wheelchair users or people pushing wheelchairs.

In addition, several to tens of unspecified patients are used or contacted with the wheelchair every day, and it is reported that bacteria and viruses of several tens of thousands / cm2 to several hundreds of thousands / cm3 are latent on the surface of wheelchairs.

A large amount of bacteria and viruses such as Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Aspergillus and the like which are harmful to the human body are detected in the above wheelchair, , And even if you wash your hands, it is no use even if you wash your hands by putting germs in your hands once you touch the wheelchair. So, it is only possible to sterilize the wheelchair to protect the patients from infection .

Despite the seriousness of the infection in the hospital, the government's infection management system is not equipped properly. In particular, a large amount of highly contagious respiratory syncytial virus (RSV), which is a recent problem with bacteria, has been detected, and it has been found that a large amount of respiratory syncytial virus (RSV) is transmitted through the conjunctiva or nasal mucosa of the cell fusion virus- It is also called respiratory syncytial virus or RSV. It first enters the respiratory system such as the nose, throat, mouth, and then spreads through the conjunctiva or nasal mucosa. Or spread by coughing or sneezing of the infected person.

Hospital infections extend hospital stay, increase hospitalization costs, increase hospital mortality by 35% (Ross et al, 2004), among which the incidence of ICU infections is 10 to 65% The mortality rate is 13-55%, hospital stay is delayed by 5-7 days due to hospital infection, and if the patient has AIDS patient, hepatitis carrier or endemic disease, it can infect others who use wheelchair .

In addition, patients who sit in such wheelchairs for a long period of time can not help but be exposed to such pathogens, and cause complications and skin diseases caused by exposure to bacteria for a long period of time, which seriously threatens the life of the patient.
