Insulin needle less syringe

Introduction to Needleless Syringes

Needle free syringe is a new type of medical device, also known as "high-pressure aerosol device", which is used to deliver medicine by spray the liquid medicine into tiny particles. Compared with traditional syringes, needle less syringes have many advantages, such as reducing patient pain, avoiding infectious diseases, improving drug absorption rate, and so on. At present, needle less syringes have been widely used in various medical settings, such as hospitals, community clinics, home care, etc.

Needle free syringes are usually composed of hand-held spray and liquid medicine container. The handheld spray includes the lips, the suction port, the spray port and the air pump, while the liquid medicine container includes the connecting device between the liquid medicine bottle and the spray. When using, first install the liquid medicine bottle into the connector, connect the connecting device with the handheld spray, then place the spray in the patient's mouth or nose, gently press the button on the spray, and spray the liquid medicine to the target.

There are many advantages to needle less syringes, such as not requiring the use of needles, avoiding the risk of infectious diseases; Spray the liquid medicine into tiny particles, which can be better absorbed; Easy to use, can be operated independently, without the need for professional assistance, and so on. However, when using needle free syringes, some matters should be paid attention to, such as the cleaning and disinfection of liquid medicine containers, the correct use of spray, and avoiding the spray too close when using, all of which are to ensure the safety and effectiveness of needle free syringes.

Principle of Needleless Syringes

Needle free syringe is a new type of medical device. Its principle is to use high-pressure gas to spray drugs into particles, which can be absorbed through human respiratory tract or skin to achieve the purpose of treatment or injection. The principle of the needle free syringe is similar to that of a spray, which converts the drug liquid into tiny particles, disperses the drug liquid into particles through compressed air or ultrasound, and directly injects the drug liquid into the focus.

Traditional syringes use needles to puncture the skin and directly inject drugs into the human body. The needle less syringe sprays medication through high-pressure airflow, reducing damage to the skin and also reducing side effects such as infection and pain.

The needle less syringe can also precisely control the amount and direction of drug injection, thus achieving more precise treatment and effectively improving drug absorption rate. At the same time, needle free syringes can also achieve different therapeutic effects by changing the physical properties of drugs, such as converting the medication into a gaseous state and treating respiratory diseases through inhalation.

In a word, the principle of needle free syringe is to reduce the damage to skin and achieve more accurate therapeutic effect by transforming drugs into particulate spray. It is an important representative of modern medical technology.
