Description
TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field especially, it relates to an adjustable tracheostomy plugging device. BACKGROUND
[0002] It is known that tracheotomy is an important rescue measure for maintaining airway patency and improving respiration of critical patients or moderate and severe inhalation injury, and tracheostomy patients usually need to try plugging before extubation. The purpose of trying plugging is to observe whether the patient can transition to oral and nasal breathing, and can self-expectoration after stable breathing, no chest tightness, shortness of breath and self-expectoration. The tracheostomy plugging method is as follows:
[0003] First, rubber glove finger sleeve sealing method - it is to use the finger sleeve part of a sterile rubber glove, cut off and cover the head of the tracheostomy tube, and fix it with 3M adhesive tape;
[0004] Second, transparent dressing sealing method - it is to use 3M transparent dressing to cover the tracheostomy tube, and stick to the root of the tube. If partial plugging is needed, a small hole can be made at the top end with a needle;
[0005] Third, sterile vacuum tube cap sealing method - remove the sterile vacuum tube cap, take out the rubber, and put the rubber cap into the tracheostomy tube. This method is fixed firmly and not easy to fall off, and also convenient to pull out the cap;
[0006] Fourth, Moore type dropper sealing method - cut the middle 1 / 2 of the Moore type dropper of the infusion device, cover the Moore type dropper on the tracheostomy tube. This method is convenient to obtain materials, simple to make, fixed firmly, and can also be used for partial plugging.
[0007] Fifth, tracheostomy metal tube plugging - use the rubber plug of a disposable syringe, remove it and cover the concave surface on the outer edge of the inner tube. If partial plugging is needed, a small hole can be cut in the center of the rubber plug with sterile scissors. The hole diameter gradually decreases from large to small, and gradually progresses to complete plugging.

This method cannot be adjusted according to the actual needs of the patients, which greatly affects the safety of the patients and the later rehabilitation. It is necessary to improve according to this situation. UTILITY MODEL CONTENT
