SYRINGE STABILIZER Russian patent published in 2020 - IPC A61M5/175 A61M5/31 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, specifically to a method and apparatus for stabilizing a syringe device. Device for syringe stabilization comprises base, support for syringe. Support for the syringe is vertically located above the base, lifts the fluid-filled area of the infusion set vertically above the base, the latter directs the delivery end of the section filled with fluid upward relative to the horizontal plane to use the gravitational effect on the fluid in the course of the fluid delivery from the area filled with the fluid to the patient's body. Support comprises first holder, selectively activated tube clamp. First holder has an opening for insertion of a rigid portion of the infusion set and is retained therein without additional user involvement. Selectively activated tube clamp is functionally conjugated with the first holder and is configured to clamp the flexible tube in a closed state, can be released by the user's first hand from the closed state to the open state to allow the flow of fluid medium through the flexible tube to come from the delivery end of the fluid-filled section. Flexible tube extends from the stiff portion of the infusion set and passes through the tube clamp. User's second hand remains stationary and creates a stabilizing force relative to the base when the fluid flow enters the user's second hand. In another embodiment portable base has engagement surface and support for hand. Engagement surface supports the syringe stabilizer on the working surface. Syringe support comprises the first and second channels. First canal has a longitudinal opening configured to receive a portion of the infusion set and hold the portion of the infusion set. Syringe cylinder of infusion set is oriented at an angle above horizontal axis and is held in raised position relative to base, wherein the delivery end of the syringe cylinder is deflected vertically below the syringe plunger. Second channel is located across the first channel and crosses it. Selectively activated tube clamp is located in the second channel and is capable of sliding therein. Tube clamp comprises a receiver for the tube. Receiver has a hole arranged flush with the first channel, and a clamping section. Clamping section is located transversely to the first channel and has a cross-section area adapted to jam a flexible tube of the infusion set to limit flow of fluid medium through the flexible tube when the tube clamp slides in the second channel in a direction transverse to the first channel. In another embodiment of the device, the base and syringe support arrangement allows positioning, orienting and holding the fluid-filled area of the infusion set such that the patient self-administering the therapeutic fluid can manipulate the tube clamp and a fluid-filled area with a first arm in the process of receiving the therapeutic fluid medium into the second arm by an infusion set. When the method is implemented, the tube clamp is moved into the closed position with the help of the first hand. Tube in the tube clamp is blocked by jamming. First syringe is disconnected along the thread from the connector attached to the syringe stabilization device by means of the first hand. That is ensured by stabilizing the syringe stabilizer base with the second hand such that the infusion set cannula remains attached to the second hand. Second syringe is attached to the connector by means of the first hand along the thread. First hand is used to force the tube clamp into the open position, and the second arm to have a stabilizing effect.

EFFECT: enabling the user or patient to independently administer a therapeutic drug medium or drug through an infusion set, while maintaining the first arm relative to the fixed one and manipulating the syringe with the drug with the second hand.
