Embodiment

[0040] Such as Figure 1-Figure 3 As shown, a split subcutaneous soft needle for application includes a piercing assembly 2 and a firing assembly 1, and the piercing assembly 2 and the firing assembly 1 are separately arranged and detachably connected. The firing assembly 1 is used to push the piercing assembly 2 to move relative to the firing assembly 1 from the preparation position to the piercing position.

[0041] The puncture component 2 and the launch component 1 are arranged separately, and the launch component can be reused, and only the puncture component 2 needs to be replaced, which can greatly reduce the cost of use and create conditions for further popularization and application of subcutaneous soft needles. In addition, the piercing assembly 2 and the launching assembly 1 are arranged separately, and can also be manufactured and sold separately, and the volume of the piercing assembly 2 is much smaller than the combination of the piercing assembly 2 and the firin...

Abstract

The invention relates to the field of medical instruments, and particularly discloses a split type application subcutaneous soft needle and a puncture method. The split type application subcutaneous soft needle comprises a puncture assembly and a transmitting assembly, and the puncture assembly and the transmitting assembly are arranged in a split mode and detachably connected. The emission assembly is used for pushing the puncture assembly to move from a preparation position to a puncture position relative to the emission assembly; the puncture assembly comprises an application unit and a puncture unit, and the application unit comprises a base and a subcutaneous soft needle; the puncturing unit comprises a rigid puncturing piece, and the puncturing piece is inserted into the subcutaneous soft needle and can be taken out of the subcutaneous soft needle. According to the split type application subcutaneous soft needle, the split type arrangement mode is adopted, the repeated utilization rate is improved, the use cost of a user is further reduced, and thereby the conditions are created for further application and popularization of the application subcutaneous soft needle.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a split-type subcutaneous soft needle for application and a puncturing method. Background technique [0002] Some patients with chronic diseases need long-term injections of drugs, such as diabetic patients, who need regular subcutaneous injections of insulin. In order to alleviate the pain of patients' repeated punctures, the application of subcutaneous soft needles has been widely promoted. The subcutaneous soft needle can be used for multiple injections of drugs after a single puncture, and the subcutaneous indwelling time of a single puncture can reach up to one week, which greatly reduces the pain of the patient. [0003] Due to the sterility requirements of medical devices for injection, the subcutaneous soft needles can only be discarded after a single puncture, and the user's use cost is relatively high, which is not conducive to the further promotion and application of th...
