What are the functions and precautions of a syringe?
The emergence of syringes is an epoch-making revolution in the field of medical appliances. The process of extracting or injecting gases or liquids with a needle is called injection. A syringe consists of a barrel with a small hole in the front and a matching piston mandrel, which draws the liquid or gas through the hole in the front of the barrel when the mandrel is withdrawn, and squeezes the liquid or gas out when the mandrel is pushed in.
Syringes can also be used for medical devices, containers, and, in some cases, scientific instruments for chromatography to inject through a rubber septum. Injecting gas into a blood vessel will cause an air embolism, and air is removed from the syringe to avoid embolism by inverting the syringe, tapping it gently, and squeezing out a small amount of liquid before injecting it into the blood stream.
01 Precautions for use
(1) This product is a ‘single-use’ product. Repeated use is prohibited and should be destroyed after use.
(2) This product is sterilised by ethylene oxide and must be used within the expiry date.
(3) The single package is damaged, sheath off, prohibit the use of, and do scrap disposal.
(4) The product should be stored in a ventilated and dry room with relative humidity less than 80%.
(5) After normal use, please follow the requirements of relevant regulations.
02 Use guide
(1) Tear open the single package bag and remove the syringe.
(2) Remove the protective sleeve of the syringe needle, pull the core rod for back and forth sliding, tighten the syringe needle.
(3) Then draw in the liquid, inject the needle upward, and slowly push up the core rod to eliminate air.
(4) Perform subcutaneous or intramuscular injection or draw blood.
03 Specific Guidelines for Different Types of Syringes:
1. Oral Syringes:
Ensure the patient is in an upright position when administering liquid medication orally to prevent choking.
Measure the liquid medication accurately using the markings on the syringe barrel.
2. Insulin Syringes:
Insulin syringes are for single-use only and should not be shared between patients.
Ensure proper insulin dosage calculations and injection techniques are followed as per healthcare provider instructions.
3. Feeding Syringes:
Use feeding syringes specifically designed for enteral feeding to prevent tube blockages.
Administer liquid nutrition or medications slowly and steadily to prevent aspiration.
4. IV Syringes:
Use aseptic techniques when filling IV syringes to prevent contamination.
Ensure the syringe is securely connected to the IV line before administering medications.
5. Safety Syringes:
Activate safety features on safety syringes after use to prevent needlestick injuries.
Dispose of safety syringes in designated sharps containers immediately after use.
6. Epidural Syringes:
Administer epidural medications slowly to prevent rapid absorption and potential complications.
Ensure proper placement of the epidural catheter before injecting medications.
7. Pediatric Syringes:
Use pediatric syringes with appropriate dose markings for accurate medication administration in children.
Ensure the syringe is age-appropriate and easy to handle for pediatric patients.
By following these guidelines and precautions, healthcare providers and caregivers can ensure the safe and effective use of various types of syringes in medical settings. Always consult with healthcare professionals for specific instructions and protocols related to syringe use in different medical procedures.
