Description

Technical Field

[0001] The utility model relates to the technical field of endotracheal tube fixers, in particular to an endotracheal tube fixer. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal tube into the trachea or bronchus through the oral or nasal cavity and the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure to rescue patients with respiratory dysfunction.

[0003] Since the endotracheal tube needs to be inserted into the patient's trachea or bronchus and is an interventional device, it will cause the patient to become irritable and feel severe discomfort during the intubation process. In order to prevent the patient from spitting out the endotracheal tube due to discomfort when awake, a endotracheal tube fixer is needed to fix the endotracheal tube. The existing endotracheal tube fixer will cause serious obstruction to the patient's mouth during the process of fixing the endotracheal tube, and the patient will inevitably produce saliva and sputum overflowing from the mouth during the intubation process. Therefore, when medical staff want to clean the patient's mouth, they need to disassemble the fixator to perform cleaning and nursing work, which is more troublesome and increases the labor intensity of medical staff.

[0004] The Chinese invention patent with patent application number CN202110654053.5 records a tracheal tube fixer, which exposes the patient's mouth as much as possible through the oral care areas on both sides of the arc-shaped fixing plate, so as to facilitate medical staff to clean and care for the patient's mouth. However, since the arc-shaped fixing plate is fixed to the patient's mouth, even though there are two oral care areas, the patient's mouth cannot be completely exposed, resulting in blind spots for cleaning, and the patient's mouth cannot be completely cleaned and cared for. Utility Model Content

[0005] The purpose of the present application is to provide an endotracheal tube holder to solve the problem that the existing endotracheal tube holder mentioned in the above background technology cannot completely expose the patient's mouth, resulting in the existence of cleaning dead corners and the inability to completely clean and care for the patient's mouth.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a tracheal tube fixer, comprising two symmetrically arranged fixing strips and two restraining straps symmetrically connected to the two fixing strips, two connecting parts are symmetrically hinged between the two fixing strips, a clamping assembly for clamping the tracheal tube is detachably connected between the two connecting parts through a snap-on assembly, the two connecting parts can be rotated and separated from the clamping assembly respectively, the clamping assembly comprises a fixing plate, a clamping hole for inserting the tracheal tube is provided in the middle of the fixing plate, an arc-shaped clamping plate is provided in the clamping hole, an adjustment unit for moving the arc-shaped clamping plate is provided on the fixing plate, and the arc-shaped clamping plate is arranged on the adjustment unit.

[0007] Preferably, the connecting member includes two connecting rods symmetrically hinged on the adjacent sides of the two fixing bars, the two connecting rods are symmetrically fixedly connected with two groups of limiting rods near the sides of the fixing plate, the two connecting rods are clamped with the fixing plate through the two limiting rods and the clamping assembly. The advantage of such a configuration is that when medical staff need to clean the patient's mouth, the four connecting rods can be rotated in sequence and away from the fixing plate, so that the four connecting rods can be away from the patient's mouth, so that the patient's mouth can be more thoroughly exposed, thereby improving the effect of cleaning and care, and after rotating one connecting rod, the other three connecting rods are still clamped with the fixing plate through the clamping assembly, thereby ensuring that the endotracheal tube is still effectively fixed during the process of cleaning and caring for the patient's mouth, thereby improving the reliability of the fixator.

[0008] Preferably, the clamping assembly includes two cavities symmetrically opened on the top of the fixed plate, two groups of limit grooves symmetrically opened on the bottom wall of the cavity, two groups of limit rods on the connecting piece are movably inserted in the two groups of limit grooves respectively, two pressure plates are symmetrically hinged on the inner side walls of the two cavities, threaded holes are opened on the pressure plate and the bottom wall of the cavity, and the first screw is threadedly sleeved in the threaded holes on the pressure plate and the cavity. The advantage of such a setting is that the clamping work can be completed by inserting the limit rod into the limit groove, then rotating the pressure plate into the cavity, and then spirally inserting the first screw into the threaded hole on the cavity, so that the clamping operation is relatively simple and convenient, which reduces the labor intensity of medical staff and improves the efficiency of cleaning and care.

[0009] Preferably, two groups of card slots are symmetrically provided at the bottom of the pressure plate, and the two groups of limit rods on the connecting piece are movably inserted in the two groups of card slots respectively, and the sum of the depths of the card slots and the limit slots is equal to the thickness of the limit rods. The advantage of such a setting is that the card slots cooperate with the limit slots to more firmly limit and fix the limit rods, thereby ensuring the firmness of the fixator to the tracheal tube and further improving the reliability of the fixator.

[0010] Preferably, the adjustment unit includes a rectangular groove formed on the inner wall of the clamping hole, a rectangular plate being movably inserted in the rectangular groove, the arc-shaped clamping plate being fixedly connected to the side of the rectangular plate close to the center of the clamping hole, the side of the rectangular plate away from the center of the clamping hole being rotatably connected to a second screw, one end of the second screw away from the rectangular plate is threadedly inserted on the inner wall of the rectangular groove, one end of the second screw away from the rectangular plate passes through the inner wall of the fixed plate and is fixedly connected to a knob. The advantage of such an arrangement is that medical staff only needs to rotate the second screw to drive the arc-shaped clamping plate close to the endotracheal tube inserted into the clamping hole until it is clamped, thereby effectively simplifying the endotracheal tube clamping operation.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] 1. In the utility model, by setting two connecting pieces hinged between two fixed strips, medical staff can rotate the two fixed strips in sequence and move them away from the patient's mouth when cleaning and caring for the patient's mouth, so that the patient's mouth is more thoroughly exposed, the cleaning dead angle is reduced, and the effect of cleaning and caring for the patient's mouth is improved.

[0013] 2. In the utility model, by setting four connecting rods, when cleaning and caring for the patient's mouth, after rotating one connecting rod away from the patient's mouth, the other three connecting rods are still connected with the fixing plate through the clamping assembly, thereby ensuring that the endotracheal tube is still effectively fixed in the process of cleaning and caring for the patient's mouth, thereby improving the reliability of the fixator.
