Description
Technical Field
The utility model belongs to the technical field of medical supplies, and particularly relates to a novel trachea cannula.
Background
At present, trachea cannula can be used clinically, needs to be fixed when in use, and needs to be separated from the connection of a breathing machine when the patient airway is administrated.
After the tracheal cannula is separated from the respirator, the closure of the air supply channel is destroyed, so that air supply of a patient is interrupted and aerosol is generated to be sprayed out, thereby causing environmental pollution.
When the tracheal intubation fixing device is adopted, the pressure injury of the lips and the tongue surface of a patient is easily caused; the fixed tracheal catheter and the fixed bite-block almost seal the oral cavity of the patient, so that the patient is uncomfortable, and the nurse is not convenient to carry out oral care and observation of the oral hygiene condition.
The utility model is fixed by adhesive plaster or tape, which needs special tooth pad to keep the mouth open properly to prevent the trachea cannula from not ventilating effectively due to the occlusion of the patient. However, the adhesive plaster is easy to lose viscosity after being wetted by saliva, so that the tracheal cannula is pulled out of the airway; the bite block is easy to be pushed out of the molar by the tongue of the patient, so that the function of supporting the teeth is lost; the bite block is made of hard material, so that when the lips and the tongue of a patient move, the bite block can also scratch the gum, the tongue surface and the upper jaw, so as to cause erosion and bleeding of the friction part. According to the report of the literature, the incidence rate of the oral cavity pressure injury of the patient with the tracheal cannula reaches 22.16 percent, the oral lip pressure sore is generated, the pain of the patient with the tracheal cannula is increased, the tolerance degree of the patient to the tracheal cannula is reduced to a certain extent, and the recovery of the disease is not facilitated.
Patent document CN205759092U provides a drug administration type trachea cannula with a bite-block, which comprises a trachea cannula, wherein the far end of the trachea cannula is sleeved with a cuff, the far end of the trachea cannula is provided with a drug injection tube, the mouth of the drug injection tube is a drug injection mouth, the drug injection tube is communicated with the cuff through a tunnel formed in the wall of the trachea cannula, two sides of the cuff are respectively provided with drug administration micropores, and the trachea cannula is provided with the bite-block. Although the problem of drug administration in the tracheal cannula is considered, the effect of the filling of the tracheal cannula cuff on preventing the respiratory tract air leakage of the patients with the trachea is ignored, and the design of the drug administration micropores in the cuff breaks the air tightness of the cuff; in addition, the tooth pad design of the patent only increases the thickness of the outer surface of the tracheal cannula to form a fusiform shape, is not enough to resist the biting force of a patient, and cannot play a role in preventing the tracheal cannula from being bitten and bitten.
