summary:
purpose:of this paper is to explore the effect of centralized cleaning and disinfection of the tourniquet, and to provide a basis for the establishment of standardized disinfection management of the tourniquet in the disinfection supply room.
method:200 tourniquet after use were divided into observation group and control group according to different disinfection treatment methods, each group had 100 tourniquet. The observation group was soaked in acidified water for 3 minutes, kneaded with washing powder, then washed under running water, dried and packaged. The control group was soaked in enzyme for 5 minutes, then soaked in acidified water for 3 minutes, rinsed under running water, and dried the package.
results:The qualified rate of the tourniquet in the observation group was better than that in the control group.
Conclusion:can ensure the quality of disinfection, eliminate security risks, reduce costs and improve economic efficiency.

Background
tourniquet is a frequently used diagnostic and therapeutic product in clinical departments, such as intravenous infusion and blood collection. The tourniquet is usually a repeated item used by the patient, which is in direct contact with the patient's skin, usually with a large number of pathogenic bacteria, especially when the blood is contaminated, it is easy to become a hidden danger of hospital infection [1]. For a long time, due to various conditions, it is difficult to carry out standardized cleaning and disinfection of the tourniquet. In January 2014, the disinfection supply room of our hospital began to centralize the treatment and supply of tourniquet used in the whole hospital. Practice has proved that tourniquet management can standardize the treatment method, ensure the disinfection quality of tourniquet, and effectively block iatrogenic infection.
1 Data and methods
1.1 general information.200 tourniquets were selected from surgical department, emergency transfusion room and outpatient department in January 2015. The diameter and length of each tourniquet in the two groups were the same, and the degree of old and new and bacterial contamination were basically the same. Cut from medical rubber tube.
1.2 method
1.2.1 Grouping The recovered tourniquet 200 roots were divided into observation group and control group according to different cleaning and disinfection methods, with 100 roots in each group.
1.2.2 The cleaning observation group was soaked in acidified water for 5 minutes, then rubbed with 30 ℃ warm water plus washing powder, washed repeatedly under running water, then put into a drying cabinet for drying, set the temperature at 70 ℃, run for 15 minutes, and dry thoroughly. The control group was soaked with enzyme for 5 minutes, then soaked in acidified water for 5 minutes, washed under running water, and then put into a drying cabinet for drying, set temperature 70 ℃, running for 15 minutes.
1.2.3 After the two groups of packaging are thoroughly dried, the staff in the cleaning area shall wash their hands carefully and then pack them. 25 tourniquets shall be neatly put into a special cleaning plastic bag for packaging and sealing, the disinfection date shall be printed at the sealing place, stored in a special rack, and supplied to clinical departments for standby.
1.2.4 Evaluation Criteria ① Visual inspection: tourniquet is fresh in color, free from dirt, yellowing,
sticky, good elasticity for qualified products, otherwise eliminated. ② Monitoring of disinfection effect: The two groups of disinfected tourniquet were sampled at the same time for 5 days, and 10 tourniquet were taken each time for sampling and testing by a special person. The tourniquet was smeared and sampled with cotton swabs soaked with neutralizer respectively, and the cotton end was cut into the test tube by aseptic operation method, and the 5 petri dishes were inoculated with 2 ml respectively, poured into the culture medium, cultured at 37 ℃ for 72 hours, and counted the number of colonies.
2 Results
2.1 tourniquet cleanliness observation group visual tourniquet bright color, no dirt on the surface. No yellow, sticky, good elasticity. The control group visual tourniquet color dark, sticky phenomenon, poor elasticity.
2.2 the degree of bacterial contamination. Immediately after disinfection, 50 tourniquets were continuously sampled in each group, and the surface of each tourniquet was sampled. A total of 100 samples were detected. The results showed that there was no significant difference in the degree of tourniquet contamination between the two groups with the same number (P>0.05). But the two groups at the same time 1, 2, 4, 6, 7 days of sampling detection, the control group in the fourth day of tourniquet surface has pathogenic bacteria growth, and the observation group in the fourth day is still no pathogenic bacteria growth, the total number of bacteria did not exceed the standard. Considering that the preservation environment of clinical departments is not as good as the storage area of sterile articles in the supply room, the validity period is set at 7 days.
3 Discussion
nosocomial infection of dangerous goods according to its degree of harm is divided into three categories: high dangerous goods, medium dangerous goods and low dangerous goods. Among them, moderately dangerous goods are only in contact with the skin and mucous membranes, and do not enter the sterile tissue. Such goods include tourniquet, tongue depressor, thermometer, etc. The tourniquet is an indispensable appliance in clinical medical care. Because of its high frequency of use in clinical work, the tourniquet is contaminated from time to time. According to my country's "Disinfection Management Measures", the tourniquet must reach a high level of disinfection, that is, all bacterial propagules, viruses, fungi and their spores and most bacterial spores should be killed. In the past, we often encountered two kinds of situations in the process of applying disinfection tourniquet: the soaking time of disinfectant is too short, the disinfection effect is poor, and the qualified rate of bacteriological detection of tourniquet is low; The soaking time of disinfectant is too long, which is easy to cause aging of tourniquet materials and greatly reduce its service life [2]. The new method not only ensures the quality of disinfection, but also conforms to the treatment procedure of cleaning and disinfection of general contaminated medical instruments. And avoid tourniquet surface yellow, sticky. In this paper, we can see that the two cleaning methods, from the cleanliness of the observation group plus washing powder scrub is significantly better than the control group, the observation group only 1 tourniquet needs to be eliminated, the elimination rate is 1%; the control group has 15 tourniquets need to be eliminated, the elimination rate is 15%. The elimination rate of the control group was also significantly higher than that of the observation group, and the storage time was insufficient in the observation group. It improves the service life of tourniquet, and also brings good social and economic benefits. It greatly reduces the pressure on the supply and demand of tourniquets, makes the tourniquets one-person use fully guaranteed, and also reduces the hidden dangers of hospital infection [3].
