Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to medical unplanned tube drawing warning reminding device.
Background
Unplanned extubation refers to the accidental detachment of a catheter, or the automatic extubation of a patient due to discomfort and without the consent of a medical worker, and also to extubation caused by improper operation of a medical worker. The pipeline is maintained to the life of a patient, once unplanned tube drawing happens, if untimely tube drawing or improper treatment is found, the pipeline can become a lethal reason of the patient, not only can the organism tissue of the patient be damaged, the operation curative effect be influenced, the pain and the economic burden of the patient are increased, the hospitalization days are prolonged, the doctor-patient contradiction is caused, and in severe cases, the condition of the patient can be suddenly changed, so that the life is threatened; the tube replacement not only can increase the pain of a patient, but also has the risks of damaging the operation area, puncturing the anastomotic stoma and the like because some intracavity catheters are placed in the operation, and the difficulty of tube replacement is high. In the case of endotracheal intubation, when unplanned extubation occurs, it can result in damage to the airway mucosa of the patient, possibly with bronchospasm, asphyxiation, tracheal injury, aspiration pneumonia, hypotension, arrhythmia, cardiopulmonary failure, and even death. The harmfulness after the extubation is caused is mainly determined by the fact that whether the intubation is needed or not and the intubation is difficult. It was found that the mortality rate of re-intubation was 7 times higher than that of patients who did not undergo unplanned extubation. And the mechanical ventilation time is increased by intubation, so that the occurrence probability of complications such as hospital acquired pneumonia is increased, and the waste of medical resources is caused. Since unplanned extubation is a risk factor causing high fatality rate and morbidity and is closely related to the utilization of medical resources, scientific design and effective intervention are of great significance in ensuring the safety of patient catheterization.
At present, the following ways are commonly used to avoid unplanned tube drawing, 1, the fixing method of the pipeline is continuously improved, for example, the fixing is carried out by 3M adhesive tape, secondary fixing or a special fixer; 2. nurse risk assessment for extubation, identification management, and health education for patients; 3. a nurse makes a round trip and shifts to follow up the attention of the patient; 4. applying limb protective restraint to the patient; 5. sedatives and analgesics may be administered to the patient to reduce discomfort.
Although an advanced fixing method is adopted, the patrol of medical staff and the nursing of family members of patients are enhanced, the uninterrupted monitoring for 24 hours cannot be guaranteed, and the patients can pull out the tubes at any time under the unconscious condition, thereby causing harm to the patients; limb protective restraint of a patient can reduce the life quality of the patient, and sedative and analgesic administration only can enhance tolerance of the patient, and the patient can be pulled out of the tube at any time in an unconscious state, which causes serious consequences.
