Automatic sputum suction type artificial airway and sputum suction system with same

Abstract

The invention discloses an automatic sputum suction type artificial airway. The automatic sputum suction type artificial airway comprises an airway duct, wherein an air ventilating channel is arranged inside the airway duct, and an air inflation bag and an air inflation tube are arranged on the airway duct. The automatic sputum suction type artificial airway is characterized in that a sputum suction tube is arranged in the air ventilating channel, and a sputum suction channel is formed inside the sputum suction tube. A sputum suction system comprises a sputum collecting bottle, a sputum-pumping pump and a control circuit, wherein a sputum inlet tube and a sputum outlet tube are arranged on the sputum collecting bottle, a sputum-pumping inlet tube is arranged on the sputum-pumping pump, the sputum inlet tube is communicated with the sputum suction tube, the sputum-pumping inlet tube is communicated with the sputum outlet tube, and the control circuit controls the sputum-pumping pump to carry out sputum pumping. The automatic sputum suction type artificial airway and the sputum suction system avoid stimulation caused by an existing movable sputum suction tube to the trachea wall of a patient in the process of sputum suction, and damage caused by the existing movable sputum suction tube to trachea mucosae, overcome the defect that hypoxia is caused by removal of a respirator, and relieve pain of the patient. Medical workers only need to carry out analysis on the symptoms and the physical sign of the patient, and set relevant parameters of a device, the device can carry out automatic sputum suction, and workload and working intensity of the medical workers are reduced.

Description

technical field [0001] The invention relates to an automatic sputum suction type artificial airway and a sputum suction system formed thereof, which belong to the field of medical equipment. Background technique [0002] An artificial airway is a gas passage established by placing a catheter through the upper respiratory tract into the trachea or directly into the trachea. The artificial airway is an effective connection between the physiological airway and air or other air sources to ensure the patency of the airway, and provides conditions for the effective drainage, patency, mechanical ventilation, and treatment of lung diseases. [0003] Establishing an artificial airway through tracheal intubation and tracheotomy is an important measure in the rescue of critically ill patients with respiratory dysfunction. It is the most effective and mature technical means for rescue and nursing of first aid and critically ill patients. It is the most widely used, most effective and...

AI Technical Summary

Problems solved by technology

[0006] 2. Reasons such as artificial airway itself and sedation cause the weakening and disappearance of cough reflex and function, resulting in increased accumulation of sputum

[0007] 3. The artificial airway inserted into the trachea stimulates the tracheal mucosa, resulting in increased secretions

When the sputum accumulated between two times of sputum suction does not bring changes in symptoms and signs of the patient, it will also cause the cilia of the trachea wall in the corresponding area to fall due to the long-term accumulation of sputum on the inner wall of the trachea. The final result is that the sputum cannot be released Lung tissue reaches the trachea by flapping cilia

At the same time, the non-stop observation of symptoms and signs also brings a lot of workload and work intensity to medical staff.

[0010] 2. The current sputum suction method is highly irritating, and the suction tube touching the tracheal wall will cause severe discomfort to the patient, and repeated sputum suction will also cause damage to the tracheal mucosa

Increase the patient's fear of sputum suction, which is not conducive to the patient's cooperation with treatment

[0011] 3. Moreover, patients with mechanical ventilation need to separate the air supply pipeline, and the suction time can only be controlled within 15 seconds to 20 seconds each time

Excessive time can cause patient discomfort and hypoxia

For patients with a lot of sputum, the sputum in the trachea needs to be sucked several times, which is time-consuming and labor-intensive and increases the discomfort of the patient.

[0012] 4. When such patients turn over or tap their backs for physical therapy, sputum often flows into the trachea from the bronchioles of the lung tissue in a short period of time, resulting in airway obstruction, increased respiratory resistance, and a sense of suffocation in the patient

Wherein, the suction tube 15 and the tracheal intubation tube 14 are not of an integrated structure, and the end of the suction tube 15 is likely to stimulate the inner wall of the human body's trachea, which is likely to cause injury to the patient.

Most importantly, since the gas sucked out by the suction tube 15 is not replenished into the ventilator 12, the ventilator will detect that the difference between the output gas and the input gas is not within the predetermined range, and the ventilator will always be in an alarm state. , is very unfavorable to use
