Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an electric atomizing continuous needle-free syringe. Background Art

[0002] Traditional needle-free syringes use the principle of pressure jet for subcutaneous injection. That is, the pressure generated by the pressure device inside the needle-free syringe pushes the drug liquid in the drug tube through the micropores to form an extremely fine drug liquid column, so that the drug liquid can instantly penetrate the human epidermis and reach the subcutaneous tissue. The drug liquid is absorbed in the subcutaneous tissue in a diffuse state with a diameter of 3-5 cm.

[0003] Needle-free syringes do not require needles, eliminating the pain and fear caused by needle injections. The main clinical use of needle-free syringes at this stage is to inject insulin into diabetic patients, freeing them from the pain of daily injections and improving drug absorption efficiency. Needle-free injections of insulin have achieved good clinical efficacy and are recognized by more and more doctors and patients. In the future, this technology will also be developed into vaccines and other fields.

[0004] The world's first needle-free syringe was launched in Germany in 1992. Since then, with the joint efforts of medical workers around the world, needle-free syringes have tended to be miniaturized, intelligent, and safe. For example, Chinese patent CN219878852U discloses a spring-driven needle-free syringe with a safety locking function, including a rear shell, a front shell, a button mechanism, a locking mechanism, a pressurizing mechanism, an injection push rod, and a card table. By adding a safety locking function, the operational safety of the spring-driven needle-free syringe is improved, and at the same time, the problems of excessive volume and weight of traditional spring-driven needle-free syringes are improved.

[0005] There are also relatively expensive electric needle-free syringes on the market. For example, Chinese patent CN213911791U discloses an electric needle-free syringe, which includes three first springs fixedly provided at equal distances on four sides of the inner wall of the syringe body, one end of each first spring is respectively fixedly provided with three collars, and one end of each first spring is respectively fixedly connected to the outer walls of the three collars. By designing an inner wall anti-collision device composed of the first springs and the collars, when the electric syringe is used externally, the liquid drug in the medicine tube placed inside can be effectively prevented from being impacted to generate foam, and the medicine tube can be prevented from being damaged due to severe impact, resulting in drug loss.
