Handheld duplex mixing drive device, dosing apparatus and dosing method

Abstract

The invention relates to a handheld duplex mixing drive device which comprises a casing, a motor, a push plate, a switch and a power supply. The motor and the power supply are arranged inside the casing, and positioning slots for fixing syringes of a duplex mixing device are formed in the upper side of the casing. The switch is arranged on the outer side of the casing and is of a forward gear and a backward gear which are used for respectively controlling forward rotation and reverse rotation of the motor. The motor is used for driving the push plate to move, and the push plate is used for controlling moving of push rods of the syringes. The drive device is simple in structure, uniform in thrusting, high in synchronism and accurate in control of push speed, and can be used with the duplex mixing device to achieve uniformly pushing for dosing, and thus application effect of medicine is better.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a dual-mixing driving device and a uniform-speed propulsion dispensing method for spraying hemostatic drugs or anti-adhesion drugs on wounds. Background technique [0002] The surface of the wound will bleed or ooze during surgery, and tissue adhesions are prone to occur after surgery. How to deal with the bleeding and oozing during the operation in time and prevent postoperative tissue adhesion is an important issue. At present, in the field of medical devices, hemostatic drugs such as fibrin adhesives or anti-adhesion drugs such as hyaluronic acid, chitosan, and polylactic acid copolymers are widely used. Fibrin adhesive is usually formed by mixing the two components. When it is not mixed, it is in a solution state. After mixing, it forms a gelatinous adhesive within a short time, which plays a role in blood coagulation. Anti-adhesive drugs include anti-adhesive film, anti-adhes...

AI Technical Summary

Problems solved by technology

[0004] However, the dual mixing device in the prior art is manually propelled, which inevitably has problems such as uneven thrust, poor synchronization of the syringes, and inability to accurately control the push speed during use, resulting in poor gel formation.

In addition, because the gel forming time is very short, usually only a few seconds, if there is a pause or the speed of the push is too slow during the manual push, it is easy to cause the mixed liquid to solidify at the injection seat and the nozzle, thereby blocking the syringe, and cannot Timely stop bleeding and promote wound healing
