Respiratory tract foreign matter obstruction suction device for pre-hospital first aid

Abstract

The length of the barrel of the respiratory tract foreign matter suction device for pre-hospital emergency treatment is about 30cm, and the length of the suction catheter externally connected with the barrel is about 30cm. And the pipe orifice of the external suction guide pipe is in a horn mouth shape, so that the suction area can be increased, and blocked foreign matters can be effectively sucked out. And the maximum diameter of the horn-shaped opening of the external suction catheter is between 1.1 cm and 1.3 cm and is smaller than the diameter of an adult trachea. The 120 pre-hospital first-aid doctor arrives at the site and can immediately use the device for suction, some foreign matters are clamped in the throat, the trachea orifice and the trachea below the trachea, the suction catheter can directly extend into the throat, the handle is slowly drawn back while the suction catheter extends into the throat, the negative pressure of the barrel body and the suction catheter is kept, and after the suction catheter and the barrel body have sucked matters, the drawing-back force is increased, so that the suction catheter and the barrel body are sucked out. And airway obstructions can be sucked out as soon as possible. In an emergency, an emergency doctor can insert the suction catheter into the trachea to suck out foreign matters with the help of the laryngoscope. When the masses carry out first aid, the aspiration catheter can be inserted into the throat part to suck back forcibly, and the aspiration catheter is effective for tracheal foreign body blockage near the throat part and the tracheal orifice.

Description

Technical Field

[0001] In pre-hospital emergency care, there is still a lack of an effective pre-hospital emergency device for suctioning foreign bodies from the respiratory tract that can be used immediately on-site and before being transferred from the scene to an ambulance or to the emergency department of a hospital. Striving to use an effective device as soon as possible within a short period of time after the respiratory tract is blocked by foreign bodies to remove the foreign bodies that are blocking the patient's respiratory tract is of great importance in saving the lives of patients with respiratory foreign bodies. The invention of such a device is of great significance for patients with respiratory foreign bodies. However, there is currently a lack of such equipment in pre-hospital emergency care for patients with respiratory foreign bodies. The invention of such a pre-hospital emergency device for respiratory foreign bodies can fill this gap. Background Art

[0002] Reason for invention: In the process of emergency first aid and 120 pre-hospital first aid for many years, patients with foreign bodies blocking the respiratory tract are often encountered. Some healthy patients who can stand up are suitable for the Heimlich first aid method, but some elderly and frail patients with cerebral infarction and other diseases (such as rib fractures, lower limb fractures, etc.) cannot stand up and cannot use the Heimlich first aid method. Some patients who have just undergone abdominal surgery and have various drainage tubes in the abdomen cannot use the Heimlich first aid method. We all know that suffocation is fatal. Often, patients will lose their precious lives in a few minutes. Some patients, even if they insist on going to the hospital, often fall into a deep coma due to brain hypoxia and are sent to the intensive care unit. The recovery is extremely poor, causing serious damage to the patients and bringing a great burden to their families and society. During the years of 120 pre-hospital emergency treatment, we have encountered many patients with foreign bodies blocking the respiratory tract. Most of these patients are elderly patients with many underlying diseases. Most of them are bedridden and cannot stand. Their family members cannot perform the Heimlich emergency maneuver for them. Some family members put their fingers into the patient's mouth and want to pick out the blocking foreign body from the patient's throat, but it is often counterproductive. Sometimes the fingers cannot reach the location of the foreign body, and sometimes they touch the foreign body inadvertently. Instead of picking out the foreign body, they touch the foreign body farther away. There are also some patients, especially those who have been bedridden for a long time with aspiration pneumonia. Sometimes when they expectorate, a mouthful of sticky phlegm is stuck in the trachea and throat, and it cannot be picked out by hands and chopsticks. There are also patients who are ineffective in the Heimlich emergency maneuver. In summary, patients with foreign bodies blocking the respiratory tract are in urgent need of a symptomatic treatment device for patients with foreign bodies blocking the respiratory tract. In the daily 120 emergency emergency work, I invented this suction device for foreign body obstruction in the respiratory tract. Summary of the invention

[0003] A suction device for respiratory foreign body obstruction for pre-hospital emergency treatment. In the practice of 120 pre-hospital emergency treatment for many years, I deeply understand that the precious time of pre-hospital emergency treatment is the golden period for rescuing patients. Seizing the golden time of pre-hospital emergency treatment can do great things with little money, sometimes save the patient's life, and reduce a great economic burden on the patient's family and society. The suction device for respiratory foreign body obstruction for pre-hospital emergency treatment has a tubular structure (which can be inserted into the oral cavity) with a length of about 30 cm, which is similar to the length, shape and curvature of a medical endotracheal tube, far exceeding the length of a finger and a general chopstick, and a cylinder device connected to its tail end. When the tubular structure enters the oral cavity and extends into the throat, the handle of the cylinder can be withdrawn, so that the tube mouth of the tubular structure has a suction force, which can adsorb foreign matter and sputum at the tube mouth. The tube mouth is trumpet-shaped, which can increase the area and effect of adsorption. During the process of withdrawing the handle, negative pressure attraction is formed in the tube to take out the foreign matter. Even if the tube pushes the foreign body inside when searching for it, after feeling the foreign body, knowing that it has been touched, the cylinder's suction force is increased to adsorb the foreign body to the trachea, and the foreign body can be taken out during the process of sucking the trachea back. The length and size of the suction tube at the front end of this device are basically the same as those of a normal medical tube. The tube mouth is slightly larger and trumpet-shaped, but the diameter is about 1.1 cm, which is also smaller than the diameter of a normal adult trachea. After the 120 pre-hospital emergency medical staff determines that the foreign body blocking the trachea is in the trachea, they can also insert the trachea of ​​the device into the patient's trachea with the help of an emergency laryngoscope to remove the foreign body. For non-professionals, the front end of the trachea of ​​the device can be moved as close to the throat as possible and sucked back forcefully, which is effective for blockages in the throat and tracheal opening.

Claims

1. This pre-hospital emergency suction device for foreign body obstruction of the respiratory tract is suitable for patients with respiratory foreign body obstruction (including complete and incomplete obstruction), who have difficulty breathing and are in danger of life at any time. If the patient is not in the hospital at the time of the foreign body obstruction, it is used for first aid for family members and people around him and for first aid after the 120 emergency personnel arrive at the scene.

2. It is hoped that this invention can be widely used in production and life, and can be used for patients with foreign bodies blocking the respiratory tract, who are bedridden for a long time and cannot stand up (such as patients with cerebral infarction and geriatric diseases, terminally ill patients, patients with lower limb fractures and other patients who cannot stand up). These patients cannot use the Heimlich maneuver.

3. It is hoped that this device can be widely used in 120 pre-hospital emergency rescue and for on-site self-rescue of the public when airway obstruction occurs.
