Description

airway opening aid

technical field

The invention relates to the field of medical technology, in particular to an airway opening assist device.

Background technique

Airway opening is a very common emergency rescue technique, which can be used for emergency airway opening during cardiopulmonary resuscitation or emergency airway establishment for patients with airway obstruction caused by tongue falling back due to various reasons, so as to ensure Patient has adequate ventilation and oxygen supply.

For patients who need to keep the airway unobstructed for a long time and cannot establish an airway such as tracheal intubation or tracheotomy in a short period of time, the method of supporting the mandible with both hands is often used clinically. Keep the sniffing position (or "nose sniffing position"). At this time, the three axes of the patient's mouth and throat overlap, which is most conducive to the patient's ventilation.

Among the people who die from emergencies every year, the death rate due to respiratory depression reaches 70%. Therefore, releasing the patient's respiratory depression is the key factor for successful rescue. The most commonly used method for opening the airway is to support the jaw. In addition, endotracheal intubation and tracheotomy were performed. However, the problems commonly encountered at present are: 1. People without formal training are difficult to achieve effective mandibular support at all, causing the obstruction to be unable to be removed and missing the golden time for rescue; The mandible will also be unable to keep the mandible held up effectively due to hand soreness, which will lead to (1) a decrease in blood oxygen saturation; (2) a large amount of gas is blown into the stomach during artificial oxygenation, increasing the risk of vomiting and aspiration , which greatly increases the risk of anesthesia; 3. In general anesthesia, after the patient has been injected with general anesthetic, the base of the tongue falls back and stops breathing. Weak hand strength will inevitably lead to poor lifting effect, especially for obese people, so oxygen cannot be given effectively. Due to poor mandibular lifting, the pressurized oxygen supply of the mask failed to improve the patient's oxygen reserve, resulting in insufficient time for intubation. Various complications are prone to occur; 4. For intravenous anesthesia for minor operations without intubation: (1) due to fear of prolonged respiratory arrest, medication is reduced, resulting in incomplete analgesia and sedation, and surgical stimulation leads to restlessness and cardiovascular accidents in patients; ( 2) Without muscle relaxants, it is difficult to support the jaw, which is likely to cause a series of accidents, such as cardiac arrest caused by hypoxia.

The traditional method of supporting the mandible with both hands needs to be done manually. When the artificial airway cannot be established in a short time or the establishment of an artificial airway does more harm than good, but the mandible with both hands can fully open the airway to assist ventilation (such as non-tracheal intubation general anesthesia surgery, etc.) ), it often takes a long time to keep the jaw supported. There are some problems: the doctor needs to maintain the same action for a long time, which is laborious, and sometimes the staff needs to be replaced midway; it is a waste of manpower, and a series of other related treatments may be required during first aid. If there are insufficient staff, the rescue work cannot be completed ideally. Therefore, we propose an airway opening aid to solve the above problems.

(6) Cushion pads are attached to the base 1. The cushion pads are rubber pads or cowhide pads, which are convenient for patients to use and increase the comfort of patients.

Clinical Trials:

treatment method:

Treatment group: After operation anesthesia, use the device of the present invention to assist in opening the airway.

Control group a: After surgical anesthesia, nurses with more than 3 years of experience were used to assist in opening the airway with bare hands.

Control group b: After surgical anesthesia, the nurses who have been employed for more than 1 year were used to assist in opening the airway with bare hands.

All patients underwent the same operation, and the operation time was counted.

treatment effect:

During the clinical observation process, 120 cases of the same operation were completed in all patients. During the operation, 40 clinical patients in the treatment group had an open and unobstructed airway, the average operation time was 30 minutes, and the total effective rate was 100%. In the control group of 40 clinical patients, the airway was open and unobstructed, the average operation time was 40 minutes, and the total effective rate was 100%. In the control group b of 40 clinical patients, the airway was open and unobstructed, the average operation time was 45 minutes, and the total effective rate was 100%. Comparing the treatment results of the three groups, the clinical effect of the treatment group is more significant in terms of operation time, because the labor of one nurse is reduced, which can greatly improve the operation efficiency and greatly shorten the operation time.

Calculated on an average of 40 minutes per operation per day, the use of the present invention can greatly reduce the length of operation. Through long-term clinical trials, more than 3 operations can be performed every day compared with the existing manual method, which greatly improves the operation efficiency. Moreover, the effect of opening the airway is remarkable, and the operation is simple. It only needs simple training, and even nurses who have just entered the profession can operate it, which is very convenient.
