Types of Dental injection needle


Dental injection needle

Dental injection needles are medical devices manufactured in accordance with the standard “YY 0587-2005 Sterile Dental Injection

Needles for Single Use,” primarily used for administering medications during dental treatments. Below is a detailed introduction to

dental injection needles:

I. Basic Components of Dental Injection Needles

Dental injection needles primarily consist of a protective sheath, a needle, and a hub. The protective sheath comprises a rigid mating

sheath and a rigid piercing end sheath, collectively forming a closed and sealed hard-packaged needle unit.

II. Physical Performance Requirements of Dental Injection Needles

Dental injection needles must meet a range of physical performance requirements, including but not limited to:

  1. Color Coding: Ensures clear color identification for easy differentiation and use.
  2. Connection Strength: Parts of the needle must be securely attached to prevent detachment or loosening during use.
  3. Needle Hole Patency: Ensures unobstructed needle holes for smooth drug delivery.
  4. Surface Cleanliness: The needle surface should be free from visible impurities or contaminants.
  5. Needle Tube Characteristics: Includes specifications for needle length, outer diameter, rigidity, flexibility, and corrosion resistance to maintain stability and durability during use.
  6. Needle Tip: The tip should be sharp and burr-free to minimize patient pain and enhance injection efficiency.
  7. Hub: The hub must mate securely with the syringe to prevent drug leakage.

III. Application Scenarios of Dental Injection Needles

Dental injection needles have widespread applications in dental treatments, primarily used in:

  1. Anesthesia Administration: During procedures such as tooth extractions and endodontic treatments, dental injection needles deliver anesthetic drugs into the patient’s mouth to alleviate pain and discomfort.
  2. Medication Injection: In cases of oral inflammation, infections, and other conditions, dental injection needles inject anti-inflammatory and antibacterial drugs directly into affected areas for treatment.

IV. Precautions for Using Dental Injection Needles

When using dental injection needles, the following precautions are crucial:

  1. Strict Aseptic Techniques: Ensure the sterility of the needles and the injection process to prevent cross-contamination.
  2. Proper Injection Site Selection: Choose the appropriate injection site and angle based on the patient’s condition and treatment needs.
  3. Injection Speed Control: Regulate the injection speed to avoid discomfort or drug leakage caused by too fast or too slow injections.
  4. Close Patient Monitoring: Observe the patient’s response closely during the injection and address any abnormalities promptly.

V. Market Situation of Dental Injection Needles

As dental medical technology advances and people’s awareness of oral health increases, the demand for dental injection needles, an

indispensable medical device in dental treatments, is steadily growing. Moreover, with continuous advancements in medical

technology and innovations in medical devices, the performance and quality of dental injection needles are constantly being improved

and refined.

In conclusion, dental injection needles play a vital role in dental treatments. Understanding their basic components, physical

performance requirements, application scenarios, and precautions is essential for enhancing the effectiveness and safety of dental
