This invention discloses a safe and controllable injection system for subcutaneous infusion of preparations, comprising: a shell with an internal cavity for accommodating a reservoir; a reservoir, installed within the cavity, for storing the infused drug solution; a drive assembly, located within the shell and connected to the reservoir for applying a continuous thrust to the reservoir; and a micro-infusion tubing, one end of which is sealed to the outlet of the reservoir, and the other end of which is equipped with an injection needle for puncturing subcutaneous tissue, the needle having an internal micro-volume flow path to reduce residual drug solution within the tubing. This invention uses a constant-force spiral spring as the drive source, combined with a flow-limiting tube with precisely controlled inner diameter, to provide a stable and controllable driving force throughout the infusion process, ensuring uniform drug infusion within a predetermined time, improving the stability and efficacy of drug absorption; furthermore, the infusion process eliminates the need for continuous hand-held operation by medical personnel, saving medical resources.

Control systems for infusions are described herein. An infusion control system includes a sensor and a controller. The sensor is configured to measure a subcutaneous fluid level. The control is configured to monitor the subcutaneous fluid level during a subcutaneous fluid infusion provided by an infusion system. Further the controller is configured to provide a feedback signal if the measured subcutaneous fluid level exceeds a subcutaneous fluid level threshold.

A subcutaneous infusion kit includes a hyaluronidase formulation, a concentrated immunoglobulin G (IgG) formulation, and a needle set for subcutaneously infusing the hyaluronidase formulation and the IgG formulation at an infusion site of a subject. The concentrated IgG formulation has a relatively high viscosity compared to standard therapeutic protein formulations. The needle set includes a needle for administering a useful dosage of the concentrated IgG formulation within a reasonable time frame while minimizing leakage at the infusion site and discomfort to the subject.
