Description

New suction tube

technical field

The invention relates to a medical device, in particular to a novel sputum suction tube for diluting and sucking out sputum in the lungs (trachea intubation and incision).

Background technique

For the current tracheal intubation and incision patients, they only need to inhale oxygen and do not need to use a ventilator or can temporarily separate the ventilator. When the sputum suction tube is used for tracheal intubation and incision of the airway for nursing and sputum suction, it is very easy to cause the following disadvantages: 1. During the operation of the suction tube, the suction tube is easily exposed to the air. Even strict aseptic operation by medical staff can still cause bacteria and infectious sources to invade the respiratory tract and cause lung infection. 2. The sputum in the deep part of the airway is viscous and difficult to be humidified and difficult to suck out. 3. Suction time is too long, unable to inhale oxygen and cause hypoxemia. 4. When the sputum suction tube is inserted into the airway, coughing occurs due to airway stimulation. The medical staff do not have good protection measures. Sputum and droplets are sprayed from the endotracheal tube and incision. Bacteria and infection in the sputum The source is sprayed into the air, medical staff and patients to cause cross infection. 5. The quality of the suction tube is poor, the texture is stiff, rough, the diameter of the tube is too thick, and there is no lubricant, which is easy to damage the respiratory mucosa. The above-mentioned problems cause inconvenience in the medical and nursing work, prolong the recovery and improvement time of the patient when the patient is mildly harmed, and increase the treatment cost;

a hypoxemia

(1) Cause

1. Oxygen supply is interrupted during suction, resulting in hypoxemia.

2. When sucking sputum, negative pressure suction sucks out the oxygen in the airway and the air in the lungs, and the gas entering the lungs from around the sputum suction tube is low in oxygen content, resulting in a decrease in the concentration of inhaled oxygen.

3. The process of suction repeatedly stimulates the airway, which reduces the respiratory rate and causes hypoxia.

4. The sputum is viscous, the suction time is too long, and the oxygen inhalation is interrupted for a long time can cause hypoxemia.

5. The patient has a hypoxic disease, and oxygen therapy cannot be performed during suctioning, which may lead to aggravated hypoxia.

(2) Clinical manifestations of hypoxemia

Depending on the degree of hypoxia, the clinical manifestations of hypoxemia: the initial manifestations are deep breathing, pulse strengthening, heart rate, blood pressure, and poor coordination of limbs; when hypoxia is further aggravated, it manifests as fatigue and fine motor disorders. Decreased strength, unresponsiveness, mental disorder; in severe cases, headache, cyanosis, vertigo, nausea, vomiting, tinnitus, fever all over the body, inability to move spontaneously, loss of consciousness, weakened heartbeat, blood pressure drop, convulsions, respiratory arrest, cardiac arrest .

Second respiratory mucosal injury

(1) Cause

1. The quality of the sputum suction tube is poor, the texture is stiff, rough, and the tube diameter is too thick to easily damage the respiratory mucosa.

2. The airway mucosa has inflammation, edema, spasm, and atelectasis. When the sputum suction tube sucks sputum, the resistance is large and the lubricity is poor, which may easily cause injury to the respiratory mucosa.

(2) Clinical manifestations of respiratory mucosal injury

Damaged respiratory mucosa can suck hemorrhagic sputum; fiberoptic bronchoscopic examination shows damaged mucosal erosion, congestion and swelling, oozing and even bleeding.

Three lung infections

(1) Cause

1. There is no strict aseptic operation.

2. The indoor air is not up to standard, and the suction tube is exposed to the air, causing pollution.

(2) Clinical manifestations of infection

Chills, high fever, profuse phlegm, mucus sputum, and thick sputum appear during lung infection. There are wet rales in the lungs on auscultation. X-ray examination can find scattered or patchy shadows. Sputum culture can find pathogenic bacteria.

Contents of the invention

The purpose of the present invention is to provide a novel sputum suction tube that can prevent hypoxemia, reduce respiratory mucosal damage, prevent the latter from reducing lung infection, prevent cross-infection between medical staff and patients, and is easy to operate;

In order to achieve the above object, the technical solution of the present invention is: a new sputum suction tube, including a sputum suction tube, characterized in that: the sputum suction tube is provided with a sanitary cover and a connecting tube, the connecting tube is provided with an oxygen inhalation connecting tube, and the sputum suction tube The upper end is provided with a negative pressure valve and a humidification fluid delivery port, and the lower end of the suction tube is provided with a humidification fluid outlet.

The connecting tube is connected with a tracheal intubation tube, and the tracheal intubation tube is provided with a rear tube, an inflatable tube and an air bag, and the end of the tracheal intubation tube is provided with a hole.

Lubricant is provided between the sanitary cover and the suction tube; the endotracheal tube is made of transparent soft plastic, the endotracheal tube is marked with a scale and measurement mark, and the suction tube is marked with a scale and measurement mark.

Advantages of the present invention:

1. Prevent and reduce hypoxemia

2. Reduction of respiratory mucosal damage

3. Prevent lung infection

4. Prevention of cross-infection between medical care and patients

5. Easy to operate and beneficial to clinic

6. Fully dilute the viscous sputum in the deep part of the airway to facilitate the suction of sputum.
