Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a facial auxiliary fixation bracket for nasal endotracheal intubation. Background Technology
[0002] Nasal intubation is a type of endotracheal intubation procedure in which an endotracheal tube is inserted into the patient's trachea through the nasal cavity.
[0003] Current problems with nasal intubation in oral and maxillofacial anesthesia:
[0004] 1. After the endotracheal tube is inserted through the nose, it is connected to the ventilator through an external tubing. However, the endotracheal tube is made of a relatively hard material and there is no effective external fixation device, which can easily cause excessive traction or compression on the nasal ala, resulting in soft tissue damage after surgery.
[0005] 2. Aseptic surgery requires prolonged covering of the wound with dressings. The pressure of the dressings will be applied to the endotracheal tube and external tubing, which will aggravate the damage of the endotracheal tube to the nasal tissue.
[0006] 3. Currently, the method of fixing the endotracheal tube is "using adhesive tape and PU transparent film to directly stick to the face". This method of fixation has poor retention, and the endotracheal tube will shift with external force, causing excessive damage to the nasal tissue.
[0007] 4. The nasotracheal tube is close to the oral surgical area. Even if it is well fixed with adhesive tape and PU transparent film, it may loosen to varying degrees because it is soaked in disinfectant during disinfection. As the surgery progresses, there is a possibility of it dislodging from the airway and causing anesthesia accidents. Utility Model Content
[0008] To address the aforementioned issues, this invention proposes an auxiliary fixation bracket for supporting and fixing the external endotracheal tube after nasal endotracheal intubation during general anesthesia in oral and maxillofacial surgery.
[0009] To achieve the above objectives, the present invention adopts the following technical solution, including an arc-shaped facial fixation shell, wherein the inner side of the arc of the facial fixation shell is a surface that fits against the forehead of the human body, and a first fixing strap and a second fixing strap are respectively provided at both ends of the facial fixation shell;
[0010] A sliding adjustment device is provided on the outer side of the face fixation shell. The sliding adjustment device includes two first support columns, a sliding cross column is connected between the two first support columns, and a sliding sleeve is fitted on the sliding cross column.
[0011] The sliding sleeve is provided with a tube clamping device, which includes a second support column on the sliding sleeve. A clamping seat is provided at the end of the second support column away from the sliding sleeve. The clamping seat is provided with an arc-shaped groove that matches the shape and size of the endotracheal tube. A third fixing strap and a fourth fixing strap are provided at both ends of the clamping seat.
[0012] As a preferred embodiment of this utility model, the first fixing strap and the second fixing strap are connected by a nylon hook and loop fastener structure at their respective ends, and the third fixing strap and the fourth fixing strap are connected by a nylon hook and loop fastener structure at their respective ends.
[0013] As another preferred embodiment of this utility model, the face fixing shell is provided with a transparent silicone air cushion on the side facing the human face to reduce the feeling of pressure.
[0014] As a third preferred embodiment of this utility model, the first fixing strap is 40cm long, the second fixing strap is 15cm long, the first fixing strap and the second fixing strap are both 3cm wide, the Velcro on the first fixing strap and the second fixing strap are both 10cm long, and the third fixing strap and the fourth fixing strap are of equal length, both 3cm.
[0015] As a fourth preferred embodiment of this utility model, the sliding sleeve is provided with an opening, and an L-shaped seat is provided on one side of the opening. The L-shaped seat includes a vertical plate connected to the sliding sleeve and a horizontal plate connected to the vertical plate. A limiting plate is provided on the other side of the opening. A limiting groove corresponding to the position and matching the size of the limiting plate is provided at the bend of the L-shaped seat. A protrusion for locking the limiting plate is provided on the horizontal plate of the L-shaped seat.
[0016] The beneficial effects of this utility model are:
[0017] Without a proper endotracheal tube protection and fixation device after nasal intubation, postoperative soft tissue damage to the nose and deformation or compression of the nasal tube are highly likely, which may further affect the patient's oxygen supply. Existing fixation methods are relatively rudimentary and may be prone to instability due to disinfection, accidental contact with external force, etc., leading to tube dislodgement and anesthesia accidents, posing certain safety hazards. This utility model proposes an auxiliary fixation bracket for supporting and fixing the external endotracheal tube after nasotracheal intubation in oral and maxillofacial surgery under general anesthesia. It can effectively avoid the above problems and greatly improve the safety of the patient's surgery.
[0018] This invention uses an elastic band as a fixing strap to secure the device to the patient's head. The end of the fixing strap is equipped with a Velcro fastener to accommodate patients with different head circumferences. The two sides of the fixing strap are of different lengths and are finally glued to the patient's temples to prevent the Velcro fastener from pressing on the skin behind the head when the patient is lying supine, thus improving the patient's comfort. A transparent silicone air cushion is provided at the bottom of the facial fixing shell to relieve the pressure of the device on the patient's face. Attached Figure Description
