Intermediate type nasopharynx expanding and bleeding-stopping bag and use method thereof

Abstract

The invention discloses an intermediate type nasopharynx expanding and bleeding-stopping bag and a use method thereof. The intermediate type nasopharynx expanding and bleeding-stopping bag comprises a flexible rubber hose, wherein a blind tube is arranged at one end of the flexible rubber hose while a valve is arranged at the other end of the flexible rubber hose; a soft rubber bag is fixedly arranged at the middle position of the flexible rubber hose; the flexible rubber hose runs through the soft rubber bag; the soft rubber bag and the flexible rubber hose are sealed to form an integral structure; and the flexible rubber hose in the soft rubber bag is provided with a small hole serving as a channel which allows air and a liquid to flow in and out. The intermediate type nasopharynx expanding and bleeding-stopping bag, disclosed by the invention, has a simple structure, is easy to process and produce, has a low cost, can protect the surface of a wound of the nasopharynx part safely, can stop bleeding and prevent infection efficiently and can prevent adhesion and bleeding of the nasopharynx part after an operation.

Description

[0001] technical field [0002] The invention relates to an intermediate nasopharyngeal expansion and hemostatic sac, which is a surgical device used for preventing secondary bleeding after nasopharyngeal surgery, formation of nasopharyngeal adhesion, and treating primary nasopharyngeal hemorrhage. Background technique [0003] The nasopharynx is located behind the nasal cavity and above the oropharynx, deep and hidden. Congenital nasopharyngeal atresia, choanal atresia after surgery, and secondary nasopharyngeal adhesions caused by various reasons (operation, trauma, non-specific infection, etc.) After surgery, due to the opening and exposure of the nasopharynx and adjacent wounds, It is very easy to re-adhesive, leading to the failure of the operation. The wounds of the nasopharynx are prone to ooze blood after benign or malignant tumor resection. Primary hemorrhage may occur in the nasopharynx or posterior nares. [0004] The traditional method to prevent nasopharyngea...

Problems solved by technology

[0004] The traditional method to prevent nasopharyngeal adhesions is to insert an anesthesia tube with a large diameter through the nose, and use the air bag at the end of the anesthesia tube to compress the wound. Injury to the nasal cavity, the end of the anesthesia tube often touches the pharynx wall, causing significant irritation to the pharynx, such as foreign body pressure, pain, nausea, and affecting eating, etc.

In the past, vaseline gauze, iodoform gauze, and inflatable sponge were used to stuff the front and rear nostrils for hemostasis in the nasopharynx or posterior nostrils, but this method has the disadvantage of uneven packing, and it is easy to fall off, and cannot form enough pressure on the wound. , if it is left for too long, it is easy to induce infection

And adopt above-mentioned method, patient's pain is big, and psychological burden is heavy.
