Abstract

The utility model discloses an oral intubation fixer, which comprises a fixing component and bandages, wherein the bandages are connected to two sides of the fixing component and are used for being hung on the back of an auricle; the fixed subassembly includes unable adjustment base, and the unable adjustment base is last to be fixed to be provided with the shrink tube, is provided with the internal thread on the shrink tube inner wall, and shrink tube female connection has the fixed pipe of tightening up, tightens up fixed pipe upper end and is the circumference outer wall, is provided with the external screw thread on its lower extreme outer wall, tightens up and evenly has seted up a plurality of gaps on the position that fixed pipe lower extreme was provided with the external screw thread, and the gap is vertical to be seted up downwards, and will tighten up fixed pipe lower extreme and cut apart into a plurality of arc petal column structures. The mouth cavity intubation tube has the advantages of simple structure, reasonable design, low manufacturing cost and small volume, is beneficial to observing the inside of the mouth cavity of a patient by medical staff, avoids frequent replacement and damage to the face of the patient, and also avoids the phenomenon of swelling of lips of the patient.

Description

Oral cavity cannula fixer

Technical Field

The utility model belongs to the field of medical care tools, and particularly relates to an oral intubation tube fixer.

Background

The trachea cannula is inserted into the trachea of a patient through an oral cavity, plays an important role in the rescue of critical patients, is the most common medical instrument in clinical emergency resuscitation, rescue breathing and paralysis, surgical anesthesia and airway opening, and the safe fixation of the trachea cannula is an important guarantee for the success of the intubation in use. According to the traditional tracheal intubation fixing method, the adhesive tape is firstly adopted to fix the mouth piece and the tracheal intubation, the patient further finishes the fixing of the tracheal intubation through the occlusion of the mouth piece, the adhesive tape is attached to the face, the adhesive tape is not breathable, the skin is easy to be broken, the lips are easy to swell after a long time, and the teeth are easy to loosen for the old;

the cannula fixer commonly used in the market at present totally envelops the whole oral cavity of a patient, medical personnel can not observe the condition in the oral cavity of the patient, and moreover, the cannula clamping position of the cannula fixer is smooth, the clamping effect is not good, and the cannula is easily flattened.

Disclosure of Invention

In view of the above, the present invention provides an oral cannula holder.

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

the oral intubation fixer comprises a fixing component and bandages which are connected with two sides of the fixing component and are used for being hung on the back of an auricle;

the fixing assembly comprises a fixing base, a contraction pipe is fixedly arranged on the fixing base, an internal thread is arranged on the inner wall of the contraction pipe, the internal thread of the contraction pipe is connected with a tightening fixing pipe, the upper end of the tightening fixing pipe is a circumferential outer wall, an external thread is arranged on the outer wall of the lower end of the tightening fixing pipe, a plurality of gaps are uniformly formed in the positions, provided with the external thread, of the lower end of the tightening fixing pipe, the gaps are vertically and downwards formed, the lower end of the tightening fixing pipe is divided into a plurality of arc-shaped petal-shaped structures, and meanwhile, one end of the external thread of the tightening fixing pipe is connected into the contraction pipe;

in addition, the internal thread in the shrink tube is a variable-diameter internal thread, and the large diameter of the internal thread gradually decreases along with tightening of the fixed tube in the screwing direction.

As a further improvement of the utility model, a rubber layer is attached to the inner wall of the tightening fixing pipe.

As a further improvement of the utility model, the bandages at the two sides of the fixing component are provided with adhesive tapes at the inner sides close to the fixing component for preventing the fixing component from falling off.

The utility model has the beneficial effects that: the mouth cavity intubation tube has the advantages of simple structure, reasonable design, low manufacturing cost and small volume, is beneficial to observing the inside of the mouth cavity of a patient by medical staff, avoids frequent replacement and damage to the face of the patient, and simultaneously avoids the phenomenon of swelling of the lips of the patient.
