Description

A kind of auxiliary device for sputum suction

Technical field

The utility model relates to the technical field of medical equipment, in particular to an auxiliary device for sputum suction.

Background technique

Negative pressure suction refers to a method of sucking out secretions from the respiratory tract through the oral cavity, nasal cavity, or artificial airway (tracheotomy) to keep the respiratory tract open and prevent aspiration pneumonia, atelectasis, suffocation and other complications. Indications: Comatose patients, those with excessive sputum and the possibility of suffocation, and those who need intratracheal administration, injection of contrast media or dilution of sputum. Specific operation: Adjust the negative pressure according to the patient's condition and sputum viscosity, turn the patient's head to the operator's side, cover the head opening of the sputum suction catheter with one hand, and use a sterile holding forceps with the other hand to insert the head end of the sputum suction catheter into the patient Oral pharynx, sucking out the phlegm in the oral cavity, throat and trachea. For patients with tracheal intubation or tracheotomy, sputum can be suctioned through the tracheal intubation or tracheal tube, and aseptic technique must be strictly followed.

Although the suctioning process may be uncomfortable, adults can generally tolerate it and cooperate with it. However, for children, there may be situations where children are not cooperative, and in this case, it will be difficult to suction. During the suctioning process of children, the following main problems exist: the child patients do not cooperate with opening their mouths and cannot put the suction tube into the mouth; the suctioning operation takes a long time and is painful, and the child patients will resist violently during the suctioning process; some Patients with dental problems will use their teeth to bite the sputum suction tube tightly, or even bite it off, causing the negative pressure to fail to be transmitted and the tube to fall into the trachea, causing suffocation; children's deciduous teeth are prone to loosening, and hard anti-bite devices can easily damage the teeth.

There are also technical solutions for sputum suction devices in existing patent documents. For example, the Chinese patent application publication number CN103230627A discloses a pediatric sputum suction device, which includes a sputum suction hose and a negative pressure suction device connected to the sputum suction hose. device, the insertion end of the sputum suction hose is provided with multiple sputum suction holes, the inner cavity of the insertion end is provided with a support frame with the same shape as the insertion end, and the support frame is provided with a through hole that matches the sputum suction holes; the sputum suction hose There is a pressure sensor inside near the negative pressure sputum suction device. The negative pressure sputum suction device is equipped with a pressure display screen and an alarm. The pressure sensor is electrically connected to the pressure display screen and alarm; the outer cover of the sputum suction hose is equipped with an elastic bite ring. . This solution uses an elastic bite ring to avoid adverse consequences such as interruption of the suction operation caused by the child's sudden mouth closing. However, there is no structure on how to fix the elastic bite ring. The elastic bite ring may become loose as the suction hose is inserted. Move, causing mouth discomfort.

The Chinese patent with the authorization announcement number CN213129996U discloses a sputum suction auxiliary bite device, which includes a main body plate, a tongue depressor and a second bite plate. The left side of the main plate is connected to a first bite plate, and the inside of the first bite plate A chute is provided, a tongue depressor is installed inside the chute, a connecting rod is connected to the right side of the tongue depressor, a handle is installed on the right side of the connecting rod, and a fixing block is connected to the outer wall of the connecting rod, and the second bite plate It is installed above the first bite plate, and guide rails are installed on the insides of the first bite plate and the second bite plate. A groove is provided on the inside of the guide rail, and a roller is installed on the inside of the groove. The first bite plate and the second bite plate A buffer pad is installed on the outer wall of the board, a treatment port is provided inside the main board, and a fixing belt is connected to the right outer wall of the main board. This solution only fixes the main plate through the fixing belt, but the fixing effect of the main plate is limited and the stability of the articulator is not good.
