Description

Endotracheal intubation fully rigid frame relying on the bridge of the nose

technical field

The invention relates to a medical auxiliary device, in particular to a fully rigid trachea intubation fixing frame relying on the bridge of the nose.

Background technique

At present, endotracheal intubation and mechanical ventilation are the most commonly used means for hospital rescue and treatment of patients with respiratory failure.

Endotracheal intubation can be divided into oral intubation and nasal intubation. The former is only suitable for emergency treatment of delirious or comatose patients due to poor patient tolerance and difficult oral care, and the intubation time should not exceed 72 hours. Nasal and tracheal intubation can be performed in an awake state because the intubation does not pass through the throat triangle, does not stimulate the swallowing reflex, and is easy for patients to accept. Can be used for a longer period of time (one week or longer) treatment. Therefore, the method of mechanical ventilation through nasal endotracheal intubation is more commonly used.

During mechanical ventilation with nasal endotracheal intubation, it is particularly important to keep the endotracheal tube fixed in place to prevent the tube from shifting, dislodging, and unplanned extubation in the patient's trachea. Commonly used clinical fixation methods include: medical tape fixation, Duropore tape fixation, inch tape fixation, pin fixation, etc. Nasal secretions lose their viscosity after soaking, resulting in invalid fixation or even false fixation; Duropore adhesive plaster fixation method is more expensive, and it is difficult to remove marks from the face due to the high viscosity of the adhesive plaster; inch tape fixation method is mostly on the basis of adhesive plaster fixation Strengthening the fixation with an inch belt is a good way to prevent the adhesive tape from falling off, but it is difficult to grasp during use: if the inch belt is too loose, it will not be able to fix it; if it is too tight, it will compress the skin of the nose and cheeks, causing skin damage and increasing The patient suffers; at the same time, if the alar of the nose is compressed, the catheter can be inserted too deep, and even enter the right bronchus, resulting in complications such as hyperventilation of one lung and atelectasis of the other lung; the pin method is mostly used in infants and young children. Based on the above, it can be seen that the traditional intubation fixation uses flexible materials. Strictly speaking, these flexible materials cannot be fixed in a true sense.

In recent years, solid covers and shells have been used to fix the cannula in the nose, but these solid covers and shells are still fixed and positioned with flexible materials. The elastic expansion and contraction of these flexible materials also makes it difficult to fix the cannula.

Moreover, the existing intubation tubes do not effectively protect the patient's hearing, and the patient's long-term use of a ventilator may cause noise-induced hearing loss.

Chinese patent ZL94200634.8 discloses a tracheal intubation fixing device, which consists of a bracket with an elastic semicircular body, a three-leaf double-hole fixing clip that is slidable on the surface of the bracket, and a support fixed in the triangular fossa of the auricle. It consists of a table, a T-shaped fixing ring and a flat belt-shaped connecting belt. Chinese patent ZL94200634.8 discloses a tracheal intubation fixing device, which consists of a bracket with an elastic semicircular body, a three-leaf double-hole fixing clip that is slidable on the surface of the bracket, and a support fixed in the triangular fossa of the auricle. It consists of a table, a T-shaped fixing ring and a flat belt-shaped connecting belt. However, its support and fixing point is in the triangular fossa of the auricle, which is a sensitive area of the human body. If it is too light, the fixation will not be firm, and if it is too hard, it will make the patient feel uncomfortable, and even cause unnecessary stimulation to the body organs. Furthermore, the fixing method of this design still does not remove the soft belt binding.

Chinese patent ZL97229943.2 discloses a fixer for oral tracheal intubation, which is composed of movable clips, combined clips and straps, wherein there is a semicircular rubber jaw on the movable clip, and there are 2 sets of clamps on the clip The rack has lateral protrusions on both sides of the rack, and there is also a semicircular rough jaw on the combined jaw. One end of the jaw has a square socket for the suction tube, and there is a square tooth pad underneath, and there are lip plates on both sides. There are claws on both sides of the upper side meshing with the rack, and there are ear-hole plates at both ends of the clamping valve, and the ear-hole plates are connected with straps. But it can only be used for anesthetizing patients, and its scope of use is narrow. Although the structure is thoughtful, its supporting point mainly relies on the square tooth pad inserted into the patient's mouth. Such a design is poorly tolerated and not suitable for oral care if used in conscious patients. The final fixing method of this scheme is still inseparable from tape and adhesive tape.

Contents of the invention

The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of fully rigid fixer of tracheal intubation relying on the bridge of the nose, this fixer is all made up of solid material, forms the real rigid fixation, abandons all flexible materials, It effectively solves the problems of catheter displacement, prolapse and various accidental extubation, and effectively maintains the original position of the catheter, which can effectively protect the patient's hearing.
