Drip injection, more accurately termed intravenous (IV) drip or infusion, utilizes gravity to deliver fluids steadily over time. The process involves:
- Preparation: A bag containing the desired fluid (e.g., medication, nutrients, electrolytes) is hung above the patient.
- Insertion: A thin tube, or catheter, is inserted into a vein. This catheter connects to the IV bag via tubing.
- Gravity Flow: Gravity pulls the fluid from the bag, through the tubing, and into the vein. The flow rate is carefully controlled to provide a consistent delivery.
This method contrasts with a single injection, where medication is directly introduced into a vein or muscle. The CDC emphasizes safe injection practices for healthcare providers to minimize risks (https://www.cdc.gov/injection-safety/about/index.html). Different injection methods exist, including intramuscular (IM) injections into muscles (https://www.ncbi.nlm.nih.gov/books/NBK556121/) and subcutaneous injections under the skin. IV drips, however, provide continuous fluid delivery as opposed to a single bolus of medication. (https://www.medicalnewstoday.com/articles/intravenous-injection). Examples include chemotherapy infusions (https://www.cancer.org/cancer/managing-cancer/treatment-types/chemotherapy/getting-chemotherapy.html) and hydration therapy using IV drips (https://www.bouncehydration.com/how-iv-drips-work).
