Description

Technical Field

[0001] This utility model belongs to the field of endotracheal intubation technology, specifically relating to an endotracheal intubation adjustment and fixation structure. Background Technology

[0002] Currently, endotracheal intubation via the mouth involves securing a disposable bite block to the endotracheal tube with adhesive tape, then using additional tape to fix the tube to the patient's cheek, or using a strap to wrap around the patient's neck to secure the endotracheal tube and bite block, or using an external fixation bite block. The endotracheal tube is then fixed in a butterfly shape around the mouth with tape. However, the tape is prone to coming loose, causing displacement. This also increases patient discomfort and leads to unplanned extubation.

[0003] In addition, the tape or external fixation device must be removed when changing the fixed position, which is very inconvenient and causes great trouble for nursing staff. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an adjustable and fixed endotracheal tube structure. The endotracheal tube is fixed by connecting a restraint strap through a connecting hole. The endotracheal tube passes through a supporting bite sleeve into the patient's oral cavity, where the sleeve provides support and prevents the patient from biting the tube, thus improving patient comfort. A rotating adjusting cap rotates a coaxial bidirectional screw, which drives a clamping plate to hold and fix the tube, ensuring stability and preventing dislodgement or displacement. When changing the fixing position, a sliding block slides on a sliding guide rod to the new position. A limiting rod at the bottom of the sliding block, under the action of a telescopic spring, inserts into a limiting hole to prevent displacement during fixation. This facilitates the fixing, disassembly, and repositioning of the endotracheal tube, providing significant convenience for nursing staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an endotracheal tube adjustment and fixing structure, comprising a support plate, with sliding guide rods mounted on both ends of the support plate via mounting blocks, and a limiting adjustment clamping structure for adjusting and fixing the endotracheal tube slidably provided on the sliding guide rods, the limiting adjustment clamping structure comprising a sliding block, a limiting rod, and an adjusting clamping structure; the limiting rod is installed at the bottom of the sliding block, and the adjusting clamping structure is connected to the front side of the sliding block via a connecting rod; the front end of the adjusting clamping structure passes through the support plate and is connected by a snap-fit ​​to a support engagement sleeve that is fitted onto the outside of the endotracheal tube.

[0006] As a preferred embodiment of the endotracheal tube adjustment and fixing structure of this utility model, the adjustment clamping structure has an internal mounting groove. A coaxial bidirectional lead screw is mounted in the mounting groove through a lead screw seat. A clamping arm is connected to the coaxial bidirectional lead screw through a lead screw slider. A clamping plate is mounted on the end of the clamping arm. One end of the coaxial bidirectional lead screw passes through the adjustment clamping structure and is connected to an adjustment cap. The clamping plate rotates the coaxial bidirectional lead screw through the adjustment cap and moves in opposite directions within the clamping cavity of the adjustment clamping structure.

[0007] As a preferred embodiment of the endotracheal tube adjustment and fixing structure of this utility model, a limiting cylinder is sleeved on one end of the limiting rod, the limiting cylinder is fixed to the bottom of the sliding block, and a telescopic spring connected to the top of the limiting rod is provided inside the limiting cylinder.

[0008] As a preferred embodiment of the endotracheal tube adjustment and fixing structure of this utility model, a row of limiting holes is provided on the support plate directly below the sliding guide rod, which are mutually limiting and interlocking with the limiting rod.

[0009] As a preferred embodiment of the endotracheal tube adjustment and fixing structure of this utility model, the support plate has a through groove for the endotracheal tube to move below the adjustment and clamping structure.

[0010] As a preferred embodiment of the endotracheal tube adjustment and fixation structure of this utility model, the support plate is provided with connection holes for connecting fixation straps at both ends, and restraint straps for fixation are connected to the connection holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a connecting hole to connect a restraint strap for fixation; the endotracheal tube passes through a support bite sleeve into the patient's oral cavity. The support bite sleeve supports the patient's oral cavity, preventing the patient's teeth from biting the endotracheal tube, providing support to the patient's oral cavity, and improving the patient's comfort.

[0013] When securing the endotracheal tube, medical staff place it into the clamping cavity of the adjustable clamping structure. Rotating the adjusting cap rotates the coaxial bidirectional screw, which in turn drives the clamping plate to clamp and secure the endotracheal tube, ensuring its stability and preventing it from falling out or shifting. When changing the fixation position, the sliding block slides on the sliding guide rod until a suitable position is reached. The bottom limiting rod of the sliding block, under the action of the telescopic spring, inserts into the limiting hole of the support plate to limit the sliding block and prevent it from shifting during the fixation process. This facilitates the fixation, disassembly, and repositioning of the tube, making it very convenient to operate and providing great convenience to nursing staff. Attached Figure Description
