The fabrics to be washed in the hospital include patient clothes, bed sheets, ward towels, surgical cloths, medical staff work clothes, etc. All patients are pathogenic vectors (bacteria and viruses) and at the same time potential infected. Therefore, it is very important to ensure the safety of the entire logistics process of washing, picking up and delivering medical linen and **, to prevent all possible opportunities for contact with infectious microorganisms, and to completely isolate cross-contamination. Hospital linen washing to prevent cross-infection is first of all the source control, linen before leaving the hospital to sort, in strict accordance with the infected disease and non-infected patient linen, doctor and patient linen, children and ** linen, newborn linen and so on to take separate classification and isolation packaging, sterilization. Dirty linen should be stored in isolation and washed as soon as possible. Before washing, the washing enterprise will sort the linen sorted by the hospital according to the category, and isolate and wash it separately according to the texture, color, type of dirt, and degree of dirt. Choose the right detergent for washing according to different linen conditions. 1. In the washing process, the logistics are cleaned and dirt are separated, and the laundry mode is hygienically isolated. All textiles must flow in one direction to eliminate the source of cross-infection of dirty clothes, and at the same time prohibit the flow of air from the dirty clothes area to the clean area, and the washing equipment adopts an isolated (two-door) washing machine, with dirty clothes at the front door and clean clothes at the back door, and the middle is completely isolated by the wall. 2. Sterilization and disinfection, using steam disinfection, dry heat disinfection and ironing of ironing, chemical disinfection and other methods. 3. Separate logistics and cleaning. The logistics is composed of a washing area, a drying and ironing area, a folding area, and a clean linen storage area. 4. Dirty linen and clean linen operators have a strict division of labor to prevent secondary pollution of clean linen by operators.
Medical linen washing quality standards.
The dirt stains on medical linen are mainly contaminants such as medicine stains, blood stains, human excrement, and pathogenic microorganisms. It is extremely important to prevent cross-infection of linen and the spread of pathogenic microorganisms during the washing process, if the washing process is not properly handled or disinfected incompletely, it will cause cross-infection and endanger the life and health of patients. Therefore, the linen provided by medical treatment must be clean and hygienic, and pathogenic bacteria must never be allowed. The quality standards for medical linen washing are as follows: no stains on sensory standards; No cross-colouring (except for linen reasons); The white linen has good whiteness, and there is no gray and yellowish phenomenon; Workwear, ** sheets, (without elastic bands) ironing smooth, stretched, no odor, no foreign matter, no damage. Total number of microbial standard bacteria: <200cfu 25C. Causative organism: must not be detected. pH standard pH 65-7.4. Water quality is an important factor affecting the quality of medical linen washing: in the washing process, hard water will cause damage to the laundry, make the white clothes gray, yellow, destroy the fiber and color, and make the clothes hard, and the minerals of the hard water have a certain catalytic effect on the bleach (agent), and the fastness to use linen will decrease, which will lead to the damage of linen in serious cases. Therefore, the washing water must be treated with soft water. Sorting and pre-washing 1, medical staff work clothes, medical staff on duty with linen; 2. Linen in ordinary wards; 3. Polluted linen (linen that may be polluted by human excrement, blood stains, etc.); 4. Infectious linen (the source of infection can be confirmed, such as linen in infectious disease hospitals and infectious disease departments); The sorted linen is put into different washing machines for pre-washing according to the type, and the installed capacity of the washing machine is controlled at 70%-80% of the first machine volume, and the necessary sufficient liquid flow space between the linens and the appropriate detergent concentration are repeatedly impacted, peeled off and taken away the dirt, and the washing quality is ensured. Avoid excessive installed capacity affecting washing quality. Blood stains, human excrement stains, etc. belong to protein dirt, and low-temperature, low-water level pre-washing can achieve wetting and infiltration of linen, remove the yellowing and blackening of linen caused by drying or high-temperature washing, and ensure the washing quality. Sterilization and disinfectionMedical linen sterilization and disinfection can be completed by high temperature, dry heat, and chemical disinfectants. High temperature, dry heat: medical linen can be washed at a high temperature of more than 80 for 10-25 minutes, and then dried and ironed at high temperature. Chemical disinfectant: Soak in chlorine-containing bleach for 25 minutes to achieve the disinfection effect. High temperature, dry heat, chemical disinfectant input, through high temperature washing, drying, ironing these three steps to ensure that the medical linen washing meets the standard requirements of the Ministry of Health sterilization, disinfection. The corners of the medical linen after washing should not be damp to prevent secondary pollution.
