Description

Tracheal catheter fixing device with sputum suction channel and pressure sore prevention function

Technical Field

The utility model relates to a fixing device for a medical tracheal catheter, in particular to a tracheal catheter fixing device with a sputum suction channel and a pressure sore prevention function, and belongs to the technical field of medical tracheal catheter fixing tools.

Background

Tracheal intubation is a very important medical procedure, which involves inserting a specially-made tracheal tube into the trachea through the mouth or nasal cavity of a patient, thereby creating an artificial airway. On the one hand, the airway can be ensured to be unobstructed, so that air can smoothly enter the lung of a patient, the respiratory function of the patient is maintained, and particularly when the patient has emergency situations such as respiratory failure, airway obstruction and the like, the tracheal intubation can quickly and effectively save the life of the patient. On the other hand, after the trachea cannula, the device such as a breathing machine, an anesthesia machine and the like can be connected for mechanical ventilation, so that sufficient oxygen supply is provided for a patient, and carbon dioxide in the body can be discharged. In addition, the tracheal cannula can prevent patients from inhaling by mistake, for example, in patients with unconsciousness or dysphagia, and can avoid serious lung infection or choking and other dangerous situations caused by reflux of gastric contents into the airway. Meanwhile, the utility model is also convenient for the management of respiratory tract, such as the operations of sucking respiratory tract secretion, bronchoscopy, etc.

However, in clinical practice, an endotracheal tube holder has been developed for preventing deep displacement of an endotracheal tube or biting of a patient into the endotracheal tube, affecting ventilation effect, and protecting teeth and lips of the patient. With the continuous development of medical technology, tracheal catheter holders are also being continuously improved and perfected to better meet clinical demands. Currently, three ways of fixing the tracheal cannula are mainly adopted clinically:

1) The first is a common type bite-block, which is fixed by winding it around an endotracheal tube. The tooth pad is made of plastic and other materials, is cylindrical or flat, has higher hardness, can effectively separate teeth from an endotracheal tube, but is hard in material, and can greatly increase the risk of tooth injury and soft tissue pressure sores such as lips and tongues when worn for a long time. And the fixation by the rubberized fabric is not firm, and the loosening is easy to occur, so that the tracheal cannula is displaced, the position is too deep or too shallow, and the ventilation quality is influenced. And the adhesive plaster is contacted with the facial skin of a patient for a long time, so that skin allergy is easily caused or skin injury is easily caused when the adhesive plaster is torn.

2) The second is a bandage roll, and the use method is the same as the previous one. The soft tissue pressure sore has the advantages of soft material and low probability of pressure sore of the soft tissue of the oral cavity, and has the defects that the soft tissue pressure sore can be placed too deeply when the experience of a user is insufficient, the tongue is pressed, the tongue lacing and other parts are damaged, and the soft tissue pressure sore is fixed by using adhesive tape or fixing belt, so that the same problem exists.

3) And the third is various tracheal catheter fixtures, which adopts a fixing belt to fix the tracheal catheter, thus effectively solving various hidden troubles of adhesive tape fixation and having better stability. But the variety of tracheal catheter fixtures in the market is less at present, and structural design generally lacks rationality, lacks abundant protection to oral cavity and facial soft tissue, wears for a long time and forms the risk of pressure sore higher, and can only apply to in the scene of prone position basically, is difficult to satisfy the user demand of lateral position or prone position patient.
