Description

Tracheal cannula fixer

Technical Field

The patent of the utility model relates to a trachea cannula's fixer especially involves a fixer through oral cavity trachea cannula.

Background

In the clinical treatment process, a simple and quick method is usually adopted to fix the tracheal cannula in the respiratory tract after the endotracheal intubation operation of a patient is generally required, so as to achieve the purposes of preventing the tracheal cannula from slipping and shifting and preventing the tracheal cannula from being blocked in the respiratory tract. The trachea cannula is one of important measures for rescuing critically ill patients, and the oral trachea cannula has the advantages of simple and rapid operation, small wound, relatively large cannula diameter, difficult blockage by sputum and the like, and is an important rescue method for keeping respiratory tract open. Whether the tracheal cannula is fixed properly is important for effective ventilation of the patient. The middle-aged and the elderly patients often have sparse and loose teeth, the traditional tracheal catheter fixing method is difficult to ensure that the catheter is reliably fixed, and the accidental tube drawing proportion is high. The fixing of the white tape of the dental pad of the oral trachea cannula is blocked by the dental pad and the adhesive tape, so that a nurse cannot well and comprehensively observe and clean the oral cavity, and meanwhile, a patient with the trachea cannula difficultly swallows, the saliva of the oral cavity is increased, the adhesive tape and the white tape are easily polluted, and the adhesive tape and the white tape are curled and loosened. Therefore, the traditional method for fixing the tracheal cannula not only increases the workload of medical staff and reduces the comfort of a patient, but also threatens the life safety of the patient.

The "comparison of the effects of three different methods for oral tracheal intubation" was disclosed in the journal of practical medicine, 2013, 29, vol.18, page 3029, by sun cuisine et al, to conclude that: the tracheal cannula fixer fixing method is simple and convenient to operate, safe and effective in fixing, few in oral and facial complications and worthy of clinical popularization.

However, the existing fixator for the trachea cannula through the oral cavity has some defects, such as: CN2287970Y relates to a ring-sleeved molar fixed bite-block, which is fixed with molar on one side in a ring-sleeved molar manner, and a pillow strap, an insertion tube and a bite-block are respectively fixed, so as to achieve the purpose of fixing the insertion tube safely, conveniently and practically. But because the bite block is fixed in the oral cavity, the patient is very uncomfortable all the time. CN202207380U discloses a tracheal cannula fixer, which is characterized in that semi-cylindrical tooth pads are respectively arranged on the bottom surfaces of a left fixing clamp and a right fixing clamp, fixing holes are respectively arranged on the outer sides of the left fixing clamp and the right fixing clamp, fixing belts are arranged on the fixing holes, the tracheal cannula is tightly wrapped by the two fixing clamps, the two fixing clamps adjust the tightness degree of the fixing clamps for the tracheal cannula through a switch button and a sawtooth groove, the tracheal cannula is arranged in the two tooth pads in a penetrating manner, the tracheal cannula is effectively prevented from being bitten by teeth of a patient, and the tracheal cannula can be prevented from sliding up and down. This seems to be a secure attachment, but also requires the placement of a bite block within the patient's mouth, with the same discomfort problem as the previous one.

CN108671353A is a reducing tracheal cannula fixer, including left sleeve pipe and right sleeve pipe, left sleeve pipe and right sleeve pipe combination become the pipe, are equipped with the fixed plate simultaneously, but because the fixed plate hugs closely the mouth, this makes the patient have the sense of compaction when using, and is very uncomfortable, if the live time is a bit for a long time, the patient oral cavity surface easily has the ulcer, and the patient need be careful when using to pay attention to this kind of misery.

Therefore, there is a need for a fixing device for an oral tracheal cannula with good fixing effect and a comfortable fixing mode for patients

Disclosure of Invention

The utility model aims at solving the defects in the prior tracheal intubation fixing process, and provides a novel controllable tracheal intubation fixer to solve the problems.

In order to achieve the purpose, the technical scheme of the utility model is as follows:
