Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a tracheal cannula plug. Background Technology
[0002] Tracheotomy is a common surgical procedure widely used to treat various laryngeal obstructions, burns, respiratory distress in comatose patients, and as a routine procedure in various neck surgeries. After the surgery, a tracheostomy tube is placed in the patient's neck, allowing the lungs to communicate directly with the outside environment through the tube's lumen, facilitating ventilation and expectoration.
[0003] The indwelling endotracheal tube can only be removed after the patient's condition improves and respiratory function recovers. Previously, tube plugging was typically performed using a makeshift plug to seal the endotracheal tube opening. Furthermore, different diameter endotracheal tubes required different diameter plugs in clinical practice. This method was prone to the use of substandard materials, leading to the plug easily dislodging, poor plugging effect, and the plug being easily lost, causing considerable inconvenience.
[0004] Therefore, a tracheostomy tube plug needs to be designed to improve the aforementioned defects.
[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0006] The purpose of this utility model is to provide an inner tube plug for the trachea. This inner tube plug is not easy to fall off or lose, is easy to operate, and improves the sealing effect of the plug body without affecting insertion and removal, resulting in a good tube blocking effect.
[0007] This utility model provides a tracheal inner tube plug, including a plug body, a handle, and a connecting buckle; the plug body is generally conical in shape, and a conical internal cavity is provided inside the plug body; the handle is connected to the upper end face of the plug body, and the diameter of the two ends of the handle gradually decreases in the direction towards the middle; the connecting buckle includes an elastic band, a locking head, and a connecting post, one end of the elastic band is connected to the side of the upper end of the plug body, the other end of the elastic band is vertically connected to the connecting post, and the other end of the connecting post is connected to the locking head; a plurality of connecting holes are provided at equal intervals on the elastic band.
[0008] Using the above technical solution, the tube plug body is inserted into the tracheostomy cannula during use. The elastic band is passed through the neck strap of the tracheostomy cannula, and the clamp is wrapped around the strap and locked in the connection hole, making the tube plug body less likely to fall off or be lost. When it is necessary to remove the tube plug body, simply hook the handle with your finger to pull it out, which is convenient to operate. The conical internal cavity design improves the elasticity of the tube plug body, thereby improving the sealing effect of the tube plug body. The conical tube plug body can fit with tracheostomy cannulas of different specifications, and the tube plugging effect is good.
[0009] Furthermore, the diameter of the card head is larger than the diameter of the connecting hole.
[0010] Furthermore, the tube plug body and the elastic band are made of latex, silicone, or rubber.
[0011] Furthermore, the main body of the tube plug is a one-piece molded structure.
[0012] Furthermore, five connecting holes are provided at equal intervals on the elastic band.
[0013] This utility model relates to an intratracheal cannula plug. In use, the plug body is inserted into the intratracheal cannula, the elastic band is threaded through the neck strap of the intratracheal cannula, and the clamp is looped around the strap and secured in the connection hole, thus preventing the plug body from easily falling off or being lost. To remove the plug body, simply hook the handle with your finger; the operation is convenient. The conical internal cavity design improves the elasticity of the plug body, thereby enhancing its sealing effect. While ensuring a good seal, it is also easy to insert and remove. The conical plug body can fit different sizes of intratracheal cannulas, providing excellent plugging effect. Attached Figure Description
