Insulin needle less syringe

A needle free syringe uses the principle of pressure jet to complete subcutaneous injection of medication. The pressure generated by the pressure device inside the needle free syringe drives the medication in the tube to form extremely fine medication columns through micropores, allowing the medication to instantly penetrate the human epidermis and reach the subcutaneous area. The medication is absorbed in a dispersed form with a diameter of 3-5 centimeters under the skin.

Preparation before use

(1) To reduce dust and bacteria contamination of syringes and components, hands should be washed before preparation for use

(2) Before opening the packaging of the medication tube and dispensing interface, it should be confirmed whether the environment you are preparing to inject is clean. If the air flow is high, it should be minimized as much as possible, such as closing the door or window. It is not advisable to inject in densely populated or heavily polluted areas.

Step 1: Install the medication tube

Insert the threaded side of the medication tube into the head of the syringe and rotate to tighten.

Step 2: Apply pressure

Grasp the upper and lower shells of the syringe with both hands, and rotate them relative to each other in the direction of the arrow until you hear a beep sound. The injection button and safety lock both pop up, indicating that the pressurization is complete.

Step 3: Take the medicine

Take out the appropriate medication interface (different insulin medication interfaces), insert one end of the medication interface with a needle into the insulin pen/refill/bottle stopper, and connect the other end to the top of the medication tube. Vertical needle less syringe, rotate the lower shell of the syringe in the direction of the arrow, inhale insulin into the medication tube, and observe the reading value on the scale window to determine the insulin dose to be injected. Remove the medication interface and cover it with a sealing cover.

Step 4: Exhaust

Before exhaust, tap the syringe with the palm of your hand upwards to make the bubbles flow towards the top of the medication tube. Vertical syringe, then rotate the lower shell in the opposite direction to the suction to completely eliminate the bubbles.

Step 5: Injection

Disinfect the injection site, grip the syringe tightly, and place the top of the medication tube perpendicular to the disinfected injection site. Use appropriate force to tighten and make full contact with the skin. Fully relax the abdominal muscles. When injecting, press the safety lock with your index finger and press the injection button with your thumb. When you hear a clear prompt sound, keep the injection pressing state for at least 3 seconds, use a dry cotton swab to continue pressing for 10 seconds, and the drug injection is completed.

1. Reduce pain during the injection process, eliminate the fear of needle phobia in patients, and improve patient compliance;

2. Reduce symptoms of allergies, etc;

3. Improve the bioavailability of drugs in the body, shorten the onset time of drugs, and reduce costs;

4. Needleless injection does not damage subcutaneous tissue, avoiding the formation of induration due to long-term injection;

5. Almost completely eliminate cross infection and avoid the risk of occupational exposure;

6. Improve the patient's anxiety and depression, and enhance their quality of life;

1. End cap: protects the front end of the drug tube to avoid contamination;

2. Scale window: Display the required injection dose, and the number in the window represents the international injection unit of insulin;

3. Safety lock: To prevent accidental operation of the injection button, it can only work when the safety lock is pressed;

4. Injection button: The start button for injection, when pressed, instantly injects the medication into the subcutaneous area;

1. Patients who refuse insulin injection therapy;

2. Insulin "3+1" regimen for patients who receive injections four times a day;

3. Patients who already have and wish to avoid subcutaneous induration;

4. Patients whose insulin dosage increases with the duration of illness;

5. Patients with increased injection pain as the injection duration increases.
