Tracheal cannula fixing device for tracheotomy child patient

Abstract

The invention relates to the technical field of medical appliances. In a widely used clinical method for cutting the tracheal cannula of a patient with a fixed trachea, the tracheal cannula is fixed on a neck part by knotting a cotton rope, cotton sliver or gauze in tracheal cannula fixing holes at one or two ends. The invention aims to provide a tracheal cannula fixing device which can be replaced quickly and does not require knotting. The fixing device consists of a solid tracheal cannula fixing rope (2) of which the outer side cannula wall is provided with a continuous lock catch (21) and two locking devices (3). When the tracheal cannula fixing device is in use, residual parts at the two ends of the tracheal cannula fixing rope are cut in comparison to the practical neck circumference, and the two ends of the tracheal cannula fixing rope pass through the locking end (32) of one locking device, the tracheal cannula fixing holes (11) and the locking end (32) of the locking device on the other side in sequence, and are clamped by a handle latch (33) in a locking end fixing hole in one direction. Due to the adoption of the tracheal cannula fixing device, the possibility of accidental detachment of a tracheal cannula and the risks of neck skin or wound damage and infection of a patient are lowered, and the pain of the patient and the workload of medical personnel are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable tracheal cannula fixing device suitable for fixing a tracheal cannula used by children with tracheotomy. Background technique [0002] At present, the widely used method for fixing the tracheostomy tube of patients with tracheotomy is to use cotton rope, cotton strips or gauze to tie the tracheal tube fixing holes at one or both ends, and fix the tracheal tube to 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 forceps or vascular forceps to tie a knot at one or both ends of the tracheal cannula fixation hole. Each end needs to be tied with more than 3 dead knots, and the time required is at least 1 minute. Longer operation time is an obvious disadvantage for critically ill patients, especially those with obvious agitation during emergency resc...

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, More than 3 dead knots need to be tied at each end, and the time required is 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 increases the difficulty of rescuing critically ill patients and Mortality rate; 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 Rapid pulling, or even pulling the tracheal tube out of the tracheostomy opening, resulting in accidental extubation, and accidental extubation is fatal for patients with burn shock and tracheotomy patients with neck tissue swelling, and for other types of Patients also increase the chances of airway damage, bleeding and infection; 3. Increase neck wound damage: the traditional method of fixing with cotton rope or cotton tape, because the fixing rope is thin, it has a strong pressure on the neck wound, and the fixing rope is easy to be damaged by the trachea. The blood and exudate around the cannula become stiff due to pollution, and long-term friction and local skin irritation can cause skin damage on the neck wound

Especially for patients with original neck skin injuries, long-term fixation with traditional methods will not only make the neck wound difficult to heal, but also make the neck wound deepen continuously under the pressure of the fixing rope, which will bring difficulties to wound repair; 4. Increase Probability 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 neck wound, making the fixing belt a good culture medium for bacteria , increase the chances of neck skin and tracheotomy infection, especially for patients with neck wounds who need long-term tracheotomy and tracheal intubation (such as patients with extensive burns), neck wounds and tracheotomy The probability of infection is greater, and severe cases even lead to wound sepsis, which threatens the patient's life; 5. The nursing work of the fixed rope is cumbersome: in order to avoid the above 3 and 4 defects from causing damage to the patient, medical staff are required to frequently replace the trachea fixation belt, increasing The workload of the medical staff and the frequent replacement of the trachea fixation belt will bring 1 and 2 defects, causing more danger to the patient

[0004] So far, there is no clinically satisfactory tracheal tube fixation device suitable for children with tracheotomy
