At present, clinical syringes are mostly the second-generation disposable sterile plastic syringes, which are widely used because of their advantages of reliable sterilization, low cost, and convenient use. However, due to poor management in some hospitals, the repeated use of syringes is prone to cross-infection problems. In addition, needle stick injuries are prone to occur due to various reasons during the operation of medical staff, thereby causing harm to medical staff. The introduction of new syringes such as self-destructing syringes and safety syringes effectively solves the drawbacks of current clinical use of syringes, and has good application prospects and promotion value.
Current status of clinical use of disposable sterile syringes
At present, most of the clinical syringes are the second-generation disposable sterile plastic syringes, which are widely used because of their reliable sterilization, low cost, and convenient use. They are mainly used in operations such as dispensing, injection, and blood drawing.
1 Structure and use of clinical syringes
Disposable sterile syringes for clinical use mainly include a syringe, a plunger matched with the syringe, and a push rod connected with the plunger. Medical staff use the push rod to push and pull the piston to realize operations such as dispensing and injection. The needle, the needle cover and the syringe barrel are designed in a split type, and the needle cover needs to be removed before use to complete the operation. After the operation is completed, in order to avoid contamination of the needle, contamination of the environment by the needle, or stabbing others, the needle cover needs to be put on the needle again or thrown into the sharps box.
2 Problems existing in clinical use of syringes
The problem of cross infection
Cross-infection, also known as exogenous infection, refers to an infection in which the pathogen comes from outside the patient's body, and the pathogen is transmitted from one person to another through direct or indirect infection. The use of disposable syringes is simple and can better ensure the sterility of the operation process. However, there are some medical institutions, which are poorly managed or for the sake of profit, and cannot achieve "one person, one needle and one tube", and the syringe is used repeatedly, resulting in cross-infection. . According to the World Health Organization, unsterile syringes or needles are reused for 6 billion injections every year, accounting for 40.0% of all injections in developing countries, and even as high as 70.0% in some countries.
The problem of needlestick injuries in medical staff
Needle stick injuries are the most important occupational injury currently faced by medical staff, and improper use of syringes is the main cause of needle stick injuries. According to the survey, needle stick injuries of nurses mainly occurred during injection or blood collection, and in the process of disposing of syringes after injection or blood collection.
