Classification of indispensable injection needles in nursing work: a guide to improving nursing efficiency and safety
Every day in the hospital, nurses need to perform countless injections, which is not just a technical task, but also an art. Choosing the right injection needle can not only improve treatment effectiveness, but also greatly reduce patients' pain and the risk of complications. From intravenous injection needles to indwelling needles, and then to syringes of various capacities, each tool has its unique purpose and operating points.
Intravenous injection needle: a daily choice for nurses
Intravenous injection is the most common injection method in nursing work, and nurses need to choose the appropriate needle type based on the injection speed and drug type.
No. 5 half needle (purple small needle): This needle type is usually used for intravenous injection with normal flow rate and is suitable for most conventional drug infusion.
No.7 needle (black large needle): When rapid delivery of special drugs is required, this larger needle type is preferred because its design can support faster flow rates.
Indwelling needle: a necessary tool in special circumstances
The indwelling needle is designed to stay in the patient's body for a long time for continuous or repeated administration. Depending on the purpose, nurses need to choose different specifications of indwelling needles.
Blue green ultra thick needle: mainly used for imaging examinations and surgeries, due to its ultra thick design suitable for large or rapid infusion.
The pink needle is slightly thicker: suitable for surgery and childbirth, especially when moderate flow is required.
The yellow needle is thinner: it is more suitable for the elderly, children, or patients with poor vascular elasticity, and can reduce vascular damage.
Selection of syringes: practical guidance for different occasions
The capacity of the syringe directly affects the injection method and effect of the drug, and choosing the appropriate syringe is equally important for ensuring drug efficacy and patient comfort.
1ml syringe: commonly used for arm injections, suitable for small doses of medication.
2ml and 5ml syringes: These two types of syringes are commonly used for intramuscular injections, such as spanking needles, and are suitable for moderate doses of medication.
20ml syringe: commonly used for drug administration and needle pushing, especially when precise control of drug delivery speed is required.
50ml syringe: commonly used in intravenous pumps to push needles, for high-dose or long-term drug infusion.
frequently asked questions
Q1: How to choose the appropriate injection needle based on the patient's specific condition?
For intravenous injection, the patient's vascular status, required drug type, and flow rate are generally considered. The choice of indwelling needle is more based on the expected duration of use and the required flow rate.
Q2: What are the precautions for using an indwelling needle?
Ensure that the needle size matches the patient's blood vessels to avoid vascular damage caused by the needle being too large. Regularly check the retention site to prevent infection and the formation of blood clots.
Q3: What are the consequences of improper syringe selection?
Improper selection may lead to inaccurate drug dosage, affect treatment efficacy, or increase patient discomfort and the risk of complications.
conclusion
Understanding and mastering different types of injection needles and their correct uses is a fundamental skill for every nursing professional. Nurses can flexibly apply this knowledge according to specific situations in their actual work, which not only improves work efficiency, but more importantly, ensures the safety and comfort of patients.
