Needleless drug-injecting system and method thereof

Abstract

The present invention relates to a needleless drug-injecting system and a drug-injecting method thereof, wherein the needleless drug-injecting system comprises a controlling device and a needleless drug-injecting device. By using the needleless drug-injecting system and the drug-injecting method, a user is able to individually set a variety of parameters comprising usage dose of liquid medicine, shot pressure of liquid medicine, air flow rate, single-shot quantity of liquid medicine, continuous shot frequency of liquid medicine, and a continuous shot spacing time according to different liquid medicine. Thus, after setting the parameters, the liquid medicine can be injected into the dermis layer of the face skin of a human when the user using this needleless drug-injecting system to inject any one liquid medicine to the human face, therefore the liquid medicine would be absorbed by the face skin without hurting the human face.

Description

technical field [0001] The invention relates to a needle-free injection device, in particular to a needle-free injection system and an injection method thereof. Background technique [0002] In recent years, the advantages of needle-free injection devices have been recognized, the main advantages of which include: no injury to medical staff and less damage to human tissue caused by injection needles. [0003] see figure 1 with figure 2 , a perspective view and side view of an existing handheld spring-loaded needle-free injection device; and, see also image 3 , Side cross-sectional view of a handheld spring-loaded needle-free injection device. As shown in the figure, the existing hand-held spring-loaded needle-free injection device 10' includes: an inner housing 12', an outer housing 28', a skin tension spring 30', a vial 18', a spray Aperture 40', a skin tensioner 43', a hammer 44', a trigger 45', a trigger mechanism 32', and an injection delivery spring 36'.

AI Technical Summary

Problems solved by technology

[0015] B. Since the hand-held spring-loaded needle-free injection device 10' is driven by the force of the spring to complete the percussion and injection of the medicinal fluid, it can be known that the hand-held spring-loaded needle-free injection device 10' cannot Perform "continuous firing (injection)" within a certain time

[0016] C. Based on the above point B, it can also be known that the hand-held spring-loaded needle-free injection device 10' cannot set the amount of a single shot of the fluid drug
