Description
Technical Field
The invention relates to the technical field of medical supplies, in particular to a comprehensive management system for protective supplies.
Background
Infectious diseases are infectious diseases which are produced by infection of a human body by pathogenic microorganisms such as viruses, chlamydia, rickettsia, mycoplasma, bacteria, fungi, spirochetes and parasites such as protozoa, worms and medical insects and which can cause epidemics under certain conditions. Generally, the disease can be transmitted by air, contact, spray, etc. by directly contacting the infected individual, the body fluid and excrement of the infected person, the contaminated object of the infected person.
Medical institutions are special places, are highly mixed environments of infectious and non-infectious patients, and medical staff often directly or indirectly contact blood, body fluid, secretion, excrement and the like carrying various pathogenic microorganisms during work. Medical protective articles can effectively protect medical staff from being infected, and because of different infection risks of each ward and each post, the infection risk of medical institutions is generally divided into low risk (corresponding to general protection or first-level protection), medium risk (corresponding to first-level protection), high risk (corresponding to second-level protection) and extremely high risk (corresponding to third-level protection), so that a basis is provided for subsequent graded protection. Different protective articles are provided for staff of a medical institution according to risk level so as to avoid infection of medical staff.
The protective articles are worn and taken off strictly according to the requirements and the sequence, medical staff are often guided by pasting pictures and characters outside an isolation ward in medical institutions, but an effective monitoring and reminding method is not provided when the protective articles are worn and taken off mistakenly. And in the using process of the sickroom, the risk level is not fixed, but is related to the patient and the using function. When the risk level is changed in the ward, the protective articles need to be replaced correspondingly by wearing and taking off the guide characters and pictures, the workload is large, and the cost is additionally increased.
Along with the increase of the number of isolation wards in a hospital, the number of the equipped protective articles can also be increased in multiples, and because the consumption speed of each protective article is different, logistics personnel are required to often confirm whether the number of the protective articles is sufficient, the trivial degree of work is increased for the logistics personnel, and the omission of supply can also be caused.
The foregoing description is provided for general background information and is not admitted to be prior art.
