The industry standard WS310. 1-2009 "Hospital Disinfection Supply Center Part : Technical Operation Specifications for Cleaning, Disinfection and Sterilization" clearly stipulates that in the operation process of medical instruments, utensils and articles, if the disinfection is continued after disinfection, the other The moist heat disinfection temperature should be ≥90°C and the time should be ≥1 min. In order to achieve and avoid secondary pollution of the cleaned instruments caused by immersion and lubrication at room temperature, the hospital uses a constant temperature water In the heating and disinfection of lubricants, the disinfection and lubrication in the operation process are carried out simultaneously, and good results are achieved.

1. 1 Improved equipment
The internal specification of the constant temperature Water Bath used is 58cm × 48cm × 30cm, and the wall thickness is 2.5 cm. The inner wall of the Water Bath is marked with the required amount of distilled water and lubricant, which is convenient for preparation. There are two U-shaped heating pipes side by side at the bottom for rapid heating; the bottom drain is connected with a control switch and a drain pipe, and there is a partition with a size of 52cm × 42cm × 6cm above the heating pipe , which is convenient for holding equipment nets basket. A handle is provided on the right side of the cover to facilitate the opening of the cover to the opposite side. There is an operation control panel on the right side of the Water Bath , which is equipped with a temperature regulator, a temperature display screen and a power switch. Four movable feet with wheels are welded with steel pipes below functionthe water .
1. 2 How to use
Clean and disinfect the inner wall of the Water Bath before use, and add the required amount of distilled water and lubricant according to the scale on the inner wall. Turn on the power, set the temperature regulator at 95°C, and when the temperature reaches 95°C, completely soak the cleaned and dried instruments together with the basket in the lubricant. At this time, the temperature of the lubricant drops to 90°C-91°C. Maintaining the effect for 1 min can meet the requirements of moist heat disinfection. After disinfection, the instruments and baskets are dried , and after checking the packaging procedures, they are then sterilized.
2 results
The improved constant temperature Water Bath heating method can combine the lubrication into one and carry out synchronously. This improved Water Bath heating method has good constant temperature effect, simple operation, easy cleaning and disinfection, and the surface of the treated instruments is smooth , labor-saving, time-saving and labor-saving, and the work efficiency is significantly improved. It is suitable for operating rooms and supply rooms of medical units without cleaning and disinfection equipment. Both have promotional significance.
3 Discussion
It has become a trend to use fully automatic cleaning and disinfection machines to clean and treat used medical devices . Many large hospitals have introduced professional program-controlled cleaning and disinfection equipment. However, some medical devices that require manual cleaning or basic medical units have not yet introduced fully automatic cleaning and disinfection equipment, and it is difficult to prevent rust and lubrication . The hospital uses an improved constant temperature Water Bath to warm the lubricant for manually cleaned instruments , and at the same time meet the disinfection requirements. It should be noted that when there is no water in the constant temperature Water Bath, it is forbidden to turn on the power to heat, otherwise the heating tube will be burned; when filling water, do not flow water into the control box to prevent leakage; the green light of the power supply is heating, and the red light is constant temperature state; Do not touch the heating tube during use to avoid burns.
