Description

Endotracheal Tube Fixation Device

technical field

The invention relates to a medical nursing device, in particular to a tracheal intubation fixing device.

Background technique

Tracheal intubation to establish an artificial airway is widely used in the rescue of critically ill patients, such as cardiopulmonary arrest, respiratory failure, hypoxia or hypoventilation and other reasons. After successful intubation, further fixation of the endotracheal tube is required.

In actual work, due to the movement of the patient's head, the position of the inserted endotracheal tube in the mouth, trachea and other parts will change, resulting in very serious consequences: because the intubated air bag is closely attached to the airway mucosa, the endotracheal intubation After the tube is shifted, it will inevitably pull the latter, causing unnecessary mucosal damage; if it slips, it will be necessary to re-intubate the trachea, delaying the timeliness of the doctor's treatment and threatening the patient's life.

In addition, during the tracheal intubation operation, the inserted catheter is a soft plastic tube. The hard teeth in the oral cavity can easily squeeze the catheter, and the intubation tube is forced to collapse, which seriously affects the ventilation effect.

Again, when endotracheal intubation, also need to regularly carry out oral care (suction to secrete excessive saliva, viscous sputum etc.), and existing endotracheal intubation and its fixing device have taken certain oral cavity area and Bulk, making oral care difficult.

Therefore, when dealing with the problem of endotracheal intubation in critically ill patients, it is necessary to have an effective and easy-to-operate medical device for fixing the endotracheal intubation, so as to prevent the intubation from being displaced, slipped, compressed and deflated, and to facilitate follow-up oral care issues.

In the existing technical method one, the tooth pad is placed next to the endotracheal tube, between the upper and lower incisors of the patient, and the endotracheal intubation catheter and the tooth pad are bound with adhesive plasters and pasted and fixed on the cheek of the patient. The purpose is: to use the dental pad to open the mouth, avoiding the closure of the teeth in the oral cavity and crushing the cannula; at the same time, the dental pad is used as a fixing device to facilitate the use of adhesive tape to fix the cannula and reduce displacement and slippage. Disadvantages: 1. The oil secreted by the facial skin of the human body weakens or loses the adhesiveness of the adhesive tape, causing the catheter to dislocate, protrude, and pose a safety hazard; 2. The fixed adhesive tape needs to be replaced after the patient’s face is cleaned every day, which increases the nursing workload and is extremely inconvenient. Convenient; 3. After the endotracheal intubation catheter is bound and fixed with the tooth pad, it is not convenient to adjust the intubation depth according to the needs; 4. It is not convenient for medical staff to clean up the patient's oral secretions; 5. Some patients are allergic to adhesive tape, which is easy to cause allergic symptoms and irritate the skin Cause inflammation, and even epidermal ulceration leads to secondary infection. In a word, this fixation method has many disadvantages, and it is difficult to achieve effective fixation. Designing a simple, effective and easy-to-operate tracheal intubation fixation device is of great significance to clinical work.

The second existing technical method is a tracheal intubation holder with a tooth pad, which is used to fix the intubation tube by a threaded clamp, has a suction hole on the side, is equipped with a fixing belt, and has a tooth pad on the inner side. Disadvantages: 1. The intubation must go through a specific "intubation/exit channel" to enter the fixed position of the threaded clamp, and then rotate the threaded clamp to fix the intubation. The operation is cumbersome and time-consuming. Delay the timing of rescue; 2. This fixture is only provided with a sputum suction hole on one side (because the other side is provided with an insertion tube channel), which can only facilitate the suction of sputum on one side of the oral cavity and oral care. When it is thick, the liquid on one side cannot effectively flow to the opposite side, and oral secretions cannot be thoroughly cleaned; 3. The fixing belt only plays a horizontal fixing role. Although the cannula cannot move inside the fixing device, the fixing device as a whole is still It can move in parallel in the horizontal direction of the oral cavity, but the intubation tube inside the trachea will still be pulled, resulting in displacement or even slippage; Smaller, on the one hand, in the elderly and trauma patients with incomplete tooth loss, if the tooth at the dental pad falls, the function of using the dental pad to open the mouth and avoid pressure tube is completely lost; on the other hand, using The narrow tooth pad supports the occlusal force of the upper and lower gums in the mouth, and the few teeth that are in contact with the tooth pad bear a greater reaction force. For patients with loose teeth, the teeth in this part will fall off and cause other oral problems.

Patent CN204563224U is only designed with a horizontal fixing band, and the intubation fixator may still rotate and shift around the neck along with the activities of the head, and the fixing effect is not good. In addition, screw tightening and reinforcement are required during fixing, which is a cumbersome process and consumes extremely valuable rescue time.

Contents of the invention

In view of the above-mentioned technical problems, the purpose of the present invention is to overcome the existing tracheal intubation when in use, the intubation shifts, slips, becomes compressed under pressure, the oral care space is narrow, and the oral cavity teeth are missing and the teeth are loose. It is difficult to support the oral passage, fixed tape allergies and other technical problems.

The specific technical solutions are:

The tracheal intubation fixing device includes a pair of U-shaped holders and a hood, and a pair of U-shaped holders are fixedly connected by a tongue and a socket to form an oval holder;

The two ends of the long axis of the elliptical fixer have side buckles respectively, and the upper end of the short axis of the elliptical fixer has a top buckle; the hood is connected to a pair of side fixing straps and a pair of surface fixing straps; One end of the side fixing belt is connected to the side buckle, and the surface fixing belt is connected to the top buckle;

The central position of the elliptical holder has a fixed bayonet for the endotracheal intubation catheter; a phlegm suction port is located between the outer wall of the fixed bayonet for the endotracheal intubation catheter and the U-shaped holder.

The inner sides of a pair of U-shaped fixators are respectively, and the dental pads protrude from the oval-shaped fixers.

After a pair of U-shaped fixators are closed, an oval-shaped fixer is formed, which is close to the outer lips of the human oral cavity. A circular endotracheal tube fixing buckle is formed in the center of the oval-shaped fixer. The inner diameter of the endotracheal intubation tube fixing buckle is It is consistent with the outer diameter of the intubation tube, and the inner surface of the endotracheal intubation tube fixing buckle is made of frosted material, which increases the surface friction with the intubation tube to ensure that the clamping position is fixed and prevents the intubation from moving.

A pair of U-shaped holders each have a large-diameter sputum suction port, which is convenient for oral care operations through the caliber.

There is a tooth pad inside the oval fixer, which protrudes from the oval fixer, goes deep into the oral cavity, protrudes about 1-2.5cm, and its outline is the caliber of the suction port. The surface of the dental pad is covered with soft bio-silicone material to prevent the damage of hard plastic material to teeth, gums and other oral tissues.

The endotracheal intubation fixing device provided by the present invention is suitable for fixing the endotracheal intubation in emergency rescue of critically ill patients, so as to prevent it from moving with the rotation of the patient's head; the operation of fixing the endotracheal tube is extremely simple, and saves precious time for rescuing patients; The fixer occupies a small area, freeing up space for oral care; the double-sided tooth pad design solves the disadvantage of missing teeth on one side, and at the same time alleviates the damage caused by excessive local tooth pressure; the use of hypoallergenic fixing belts, Avoid using adhesive tape to directly stick to the patient's skin surface to reduce skin allergies and loosening caused by skin oil secretion and epidermal cleaning.
