Novel multi-component medical adhesive spraying device

Abstract

The invention discloses a novel multi-component medical adhesive spraying device. The device comprises a spray head, a first injector and a second injector, wherein the first injector and the second injector are arranged in parallel and connected with the spray head; each of the first injector and the second injector comprises a charging barrel, a piston part which is arranged in the charging barrel and can slide along the inner wall of the charging barrel in a sealed manner, a plugging part arranged at the opening end of the charging barrel, and an injector operating rod assembly for controlling the piston part to slide along the inner wall of the charging barrel in a sealed manner; each piston part divides the internal space of the corresponding charging barrel into a first storage chamber between the piston part and the corresponding plugging part and a second storage chamber between the piston part and the closed end of the charging barrel; each piston part is provided with a firstvalve which can be opened only when the piston part moves towards the side of the corresponding plugging part; the closed end of each charging barrel is provided with a liquid outlet; and each liquidoutlet is provided with a second valve which can be opened only when the corresponding piston part moves towards the side of the closed end of the corresponding charging barrel. According to the invention, the operation steps of medical adhesive instrument assembling, spraying and the like can be reduced, the operation efficiency is remarkably improved, the component mixing ratio can be ensured,and the component mixing uniformity is improved.

Description

technical field

[0001] The invention relates to the technical field of medical devices, more specifically, to a novel multi-component medical glue spraying device. Background technique

[0002] In surgical operations, antibacterial and hemostasis are the basis, while suturing and tying are the two most basic operations for the repair of biological tissues. This method is not only loaded down with trivial details laboriously, and easily causes bleeding and new injury, brings more misery to the patient; For those large area oozing blood that cannot find bleeding point, traditional suturing operation is more difficult to handle. The emergence of medical glue can stop the bleeding of small blood vessels or seal the surface of cancer serosa, which has played a good role. Sealing small blood vessels with broken wounds can effectively stop bleeding. At the same time, the glue film isolates tissues and bacteria, and has anti-infection and protection The role of the wound surface. ...
