Tracheal tube fixation supplies

Abstract

The invention relates to the technical field of medical instruments. The method of fixing the tracheal tube of patients with tracheotomy widely used in clinic is to use cotton rope, cotton sliver or gauze, and tie the tracheal tube fixing holes at one or both ends to fix the tracheal tube to the neck. The object of the present invention is to provide a tracheal tube fixing device that can be quickly replaced and does not need to be knotted. The tracheal tube fixing device is composed of a hollow tracheal tube fixing rope (2) with locks (21) inside the tube walls at both ends and two self-locking devices (3). When using, first compare with the actual neck circumference, cut off the excess length at both ends of the tracheal cannula fixing rope, pass the self-locking device through the tracheal cannula fixing hole, lock the self-locking end, and then insert the locked self-locking end into the tracheal cannula for fixation Both ends of the rope are engaged with the locks inside. The invention not only reduces the probability of accidental detachment of the tracheal tube and the risk of neck skin or wound damage and infection of the patient, but also reduces the pain of the patient and the workload of the medical staff.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tracheal tube fixing article suitable for fixing a tracheal tube for patients with a tracheotomy. Background technique [0002] At present, the method of fixing the tracheal tube of patients with tracheotomy widely used in clinical practice is to use cotton rope, cotton strips or gauze, and adopt the method of knotting the fixing holes of the tracheal tube at one or both ends, and fix the tracheal tube on the neck. department. [0003] This fixation method has obvious defects, mainly including: 1. The fixation process takes a long time: each fixation needs to use two tweezers or blood vessel forceps to tie a knot at one or both ends of the tracheal cannula fixation hole. For a clear fixation effect, Each end needs to tie 3 to 4 dead knots, at least 1 minute. The longer operation time is an obvious disadvantage for critically ill patients, especially for patients with o...

Problems solved by technology

[0003] This fixation method has obvious defects, mainly including: 1. The fixation process takes a long time: each fixation needs to use two tweezers or blood vessel forceps to tie a knot at one or both ends of the tracheal cannula fixation hole. For a clear fixation effect, Each end needs to tie 3 to 4 dead knots, at least 1 minute. The longer operation time is an obvious disadvantage for critically ill patients, especially for patients with obvious restlessness during emergency rescue, which will increase the difficulty of rescue and death of critically ill patients. 2. The operation is cumbersome, which increases the risk of accidental detachment: due to the need to tie knots many times, each knot needs to use a lot of strength to ensure the effect. Once one hand is released, it is easy to cause the tracheal cannula to move to the opposite side Pulling, even pulling the tracheal tube out of the tracheotomy opening, resulting in accidental extubation, and accidental extubation is fatal to tracheotomy patients with neck tissue swelling and laryngeal edema, and increases tracheotomy for other types of patients. 3. Increased neck wound damage: the traditional method of fixing with cotton rope or cotton tape, because the fixing rope is thin, the pressure on the neck wound is strong, and the fixing rope is easily absorbed by the infiltration around the tracheal tube. Contaminated by blood exudate and become stiff, long-term friction and local irritation of the skin can cause skin damage on the neck wound

Especially for patients with original neck skin injuries, not only the neck wounds are difficult to heal, but also the neck wounds continue to deepen under the friction and pressure of the fixed rope, which brings difficulties to wound repair; 4. Increase the chance of neck wound infection: The traditional method of fixing with cotton rope or cotton belt, because the material of the fixing rope is made of cotton cloth, can absorb the sweat of the neck skin and the exudate of the wound on the neck, so that the fixing belt becomes a good culture medium for bacteria, increasing the growth of the neck skin and The chance of tube incision infection, especially for patients with neck wounds and long-term tracheostomy and tracheal intubation (such as facial and neck trauma, craniocerebral trauma coma patients), neck wounds and tracheotomy The probability of infection is higher; 5. The nursing work of the fixed rope is cumbersome: in order to avoid neck wound injury and infection of patients with tracheotomy and infection of the tracheotomy opening, medical staff need to replace the tracheal fixation belt regularly, which increases the workload of medical staff At the same time, frequent replacement of the tracheal fixation belt increases the risk of accidental extubation, causing more danger to the patient

[0004] So far, there is no clinically satisfactory protective device for tracheal tube fixation
