•St. Clair Thompson's long bladed nasal speculum-do-; long blades ( uses: in operations such as Submucous Resection of the nasal septum) •Killian's long bladed nasal speculum-do-; long blades and with handles; used more operations like SMR & Septoplasty. ( advantage: blade can be adjusted and fixed with screws, to avoid strain due to holding )
Medical syringes include disposable and safety syringes, injection pens, needleless injectors, insulin pumps, and specialty needles. [2] Hypodermic syringes are used with hypodermic needles to inject liquid or gases into body tissues, or to remove from the body.
to absorb blood and other fluids as well as clean wounds: Glucose monitor: to measure concentration of glucose in blood: Haemodialysis machine: to remove toxic materials from the blood that are generally removed by the kidneys; used in case of kidney failure [3] Hypodermic needle / Syringe: for injections and aspiration of blood or fluid from ...
Heparinised saline may be used in flushing arterial lines, to prevent clotting and blockage of the line. [citation needed] When syringes are used to perform a saline flush, it is important that the syringe not be reused for multiple patients, even though direct contact with the patient does not normally occur.

Touching the posterior wall of the sinus by the tip of the cannula may block the cannula and the fluid may not return on pumping the higginson syringe. The cannula is slightly withdrawn and it becomes patent. Blocked ostium: If the ostium of the sinus is blocked, the fluid doesn't return through it. To bypass the ostium, one more trocar and ...
The carpuject is a syringe device for the administration of injectable fluid medication. It was patented by the Sterling Drug Company , which became the Sterling Winthrop , after World War II. It is designed with a luer-lock device to accept a sterile hypodermic needle or to be linked directly to intravenous tubing line.
Some injectors are triggered by simply pushing the nose ring against the injection site. In these designs, the protective cap is the primary safety. Other designs use a safety mechanism similar to nail guns : The injection is triggered by pushing the nose ring against the injection site and simultaneously, while applying pressure, pushing a ...
