Injection Needle

Injection Needle Description

Injection needles come in various sizes and gauges, each designed for specific purposes. The gauge of a needle refers to the diameter of the cannula, with smaller gauge numbers indicating larger needle diameters. Thicker fluids or substances may require larger gauge needles for easier administration, while thinner fluids may be administered using smaller gauge needles.

Injection Needle Feature

There are several advantages of Injection Needle :

1. Drug delivery: Injection needles are used to deliver drugs directly into the body for fast, accurate, controlled drug delivery. Injections can be used to treat diseases, provide first aid, administer vaccines, deliver nutritional solutions, etc.

   
   

2. Intravenous blood collection: Medical personnel use an injection needle to perform intravenous blood collection, drawing a blood sample from a patient's vein for laboratory testing and diagnosis.

   
   

3. Injection anesthesia: The needle plays a key role in the anesthesia process. They are used to gradually inject narcotic drugs into the patient's blood circulatory system to achieve general or local anesthesia.

   
   

4. Taking body fluid samples: In addition to taking blood, an injection needle can also be used to take samples of other body fluids, such as spinal fluid or joint fluid, for pathology or diagnostic testing.

   
   

5. Contrast injection: An injection needle is used to inject contrast into the body to enhance the visualization of medical imaging. This is important for diagnosing and assessing the condition of organs and tissues.

   
   

   In general, injection needles are one of the most commonly used tools in medical practice for drug delivery, sample collection, anesthesia, and diagnosis. They play an important role in the medical process, ensuring that drugs and therapeutic substances reach their target locations accurately and safely.

Composition of disposable injection needle

Injection needles, also known as hypodermic needles, are medical devices used to deliver medications, fluids, or other substances into the body through injection. They consist of a hollow tube with a sharp, beveled tip and a hub that attaches to a syringe or other injection device.

The main components of an injection needle include:

1. Cannula: The cannula is the hollow tube of the needle. It is typically made of stainless steel or other materials that provide strength and rigidity. The length and gauge (diameter) of the cannula can vary depending on the intended use and the specific requirements of the injection.

2. Bevel: The bevel is the slanted or angled tip of the needle. It allows for easier penetration of the skin and tissues during an injection.

3. Hub: The hub is the connector at the base of the needle that attaches to a syringe or other injection device. It provides stability and allows for secure attachment and detachment.

Here is some additional information and considerations when performing interventional surgery with Injection Needles:

Different sizes of drug delivery tubes (injection needles) have different uses and advantages in medical practice. Here are some common sizes of drug delivery tubes and their characteristics:

Small (highly elongated) administration tubes: Small administration tubes usually have a smaller diameter (larger needle number). They are suitable for the following situations:

Small blood vessels or tissues: When drugs need to be injected into small blood vessels or tissues, small delivery tubes make it easier to penetrate and deliver drugs.

Sensitive patients: For particularly sensitive or pediatric patients, small dosing tubes can reduce discomfort and pain.

Medium dosing tube: Medium dosing tube is the most common and common size. They are suitable for a variety of administration situations, including:

Routine injection: Medium drug delivery tube can be used for general drug injection, such as liquid drug infusion, injection administration, etc.

Intravenous blood collection: The medium drug delivery tube is often used for routine intravenous blood collection to quickly collect enough blood samples for testing.

Large (shorter) tube: Large tube has a larger diameter and a shorter length. They are suitable for the following situations:

High-viscosity drugs: When high-viscosity drugs need to be injected, such as certain oils or suspensions, large tubes can make it easier to inject and reduce injection resistance.

Rapid infusion: Large dosing tubes can be used for rapid infusion in order to quickly deliver larger quantities of fluid.
