Description

Technical Field

[0001] The invention relates to the technical field of endotracheal tube fixation, in particular to an endotracheal tube fixer for prone position ventilation. Background Art

[0002] Prone ventilation is a treatment method that places the patient in a prone position (i.e., face down) for mechanical ventilation. It is mainly used to improve respiratory function, especially in patients with severe respiratory failure such as acute respiratory distress syndrome. When the human body is in a supine position, the lung tissue on the back is prone to collapse due to gravity, resulting in poor ventilation, and the compression of the heart and diaphragm will also reduce the effective ventilation area of ​​the lungs. When in a prone position, the pressure on the lung tissue on the back is reduced, and the collapsed alveoli are easier to re-expand, thereby increasing the ventilation area of ​​the lungs and improving the ventilation / perfusion ratio. Endotracheal intubation for prone ventilation refers to the technique of inserting a special endotracheal tube into the trachea through the mouth or nose when the patient is in a prone position for ventilation, and establishing an artificial airway to maintain respiratory support. The main purpose of endotracheal intubation in prone ventilation is to keep the airway open to facilitate mechanical ventilation, while preventing aspiration and airway obstruction.

[0003] The existing patent (publication number: CN115518256A) discloses "the present invention relates to the field of endotracheal tube fixation technology, a endotracheal tube fixer for critically ill patients during prone ventilation, comprising a baffle and a pipeline, a T-slot hole is provided in the middle of the baffle, and the outside of the T-slot hole provided in the middle of the baffle is fixedly connected with a fixing seat, the fixing seat comprises a fixing groove, a fixing groove is provided in the middle of the fixing seat, the T-slot hole in the middle of the baffle is consistent with the fixing groove structure, threaded grooves are provided on both sides of the interior of the fixing seat, a threaded rod is movably connected to the interior of the threaded groove on one side, a limiting groove is provided inside the fixing seat, and a baffle rod is connected through the outer wall of the fixing seat on one side, by means of the baffle, the fixing seat and the threaded rod, when in use, the fixing direction of the pipeline can be flexibly adjusted according to the facial orientation of the patient in the prone position, and the threaded rod is provided to fix pipelines of different diameters, thereby effectively improving the flexibility during fixation".

[0004] In the process of realizing this application, the inventor discovered that the prior art has the following problems: the existing endotracheal tube fixator is usually a fixing device fixed on the patient's face or mouth. When in use, the endotracheal tube is passed through the fixator to fix the endotracheal tube to realize its use function. When in use as a whole, the structure of the fixator is relatively simple, and usually only the endotracheal tube part can be fixed, and it is difficult to provide support for the patient's neck and head. Since the patient is in a prone position, the lack of support for the head and neck will affect the position of the endotracheal tube, so that the existing fixator as a whole has a relatively single functionality when in use, a small scope of application, and poor overall practicality. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a endotracheal tube fixer for prone ventilation, which solves the problems that the existing endotracheal tube fixers have a relatively simple structure, a relatively simple overall fixing form and fixing position, poor functionality, and low practicality when in use.

[0016] Working principle: When using the device, the user can first place the entire device to the position where it needs to be used through the installation mechanism. After placement, the first connecting mechanism and the second connecting mechanism are wrapped around the surface where they need to be fixed, and the first connecting belt and the second connecting belt are fixed by sticking the Velcro hook surface and the Velcro fleece surface to fix the entire device to the position where it needs to be used. After fixation, the user can adjust the position of the head support mechanism, the intubation fixing mechanism and the neck support mechanism according to the patient's personal situation. When adjusting the neck support mechanism, the user can first loosen the two fifth fixing knobs according to the patient's neck length, and adjust the two fifth fixing knobs. The position of the fourth slider in the second adjustment slot is used to adjust the distance between the two support rings, thereby adjusting the length of the telescopic plate so that the length of the telescopic plate can be suitable for the length of the patient's neck. After the adjustment is completed, the two fifth fixing knobs are tightened, and the distance between the two support rings is fixed by two positioning blocks. After the fixation is completed, the user can loosen the fourth fixing knob, change the position of the adjustment inner rod inside the adjustment outer rod, and adjust the support ring to a suitable height. After the adjustment is completed, tighten the two fourth fixing knobs to fix the height of the support ring. After the fixation is completed, the user can loosen the two third fixing knobs and align the connector through the hinge joint. The angle can be adjusted so that the trachea can better fit the curvature of the patient's neck. After the adjustment is completed, the angle of the connector is fixed by two third fixing knobs to fix the position of the patient's neck. After the neck support mechanism is adjusted, the user can adjust the position of the head support mechanism by first turning the adjustment knob to drive the threaded rod to rotate, thereby driving the third slider set on the surface of the threaded rod to move, and combining the sliding of the second slider on the surface of the sliding rod to adjust the head support mechanism to a suitable position so that the patient's entire face can fit the surface of the silicone gasket. After the adjustment is completed, the user can control the two telescopic rods to extend and contract to After the support frame is adjusted to a suitable height and the head support mechanism is adjusted, the user can adjust the intubation fixing mechanism. The user can first loosen the two second fixing knobs, adjust the position of the first slider on the slide rail surface through the connecting groove, and after adjusting to a suitable position, tighten the two second fixing knobs to fix the position of the intubation fixing mechanism. After the fixation is completed, the user can place the mouthguard into the patient's mouth, insert the tail end of the tracheal tube into the fixing tube, tighten the second fixing knob to fix the tracheal tube, and then wrap the two fixing straps around the patient's head, fix the position of the two fixing straps with Velcro, and complete the overall use and installation of the device.

[0017] The present invention provides a tracheal tube holder for prone position ventilation. It has the following beneficial effects: The present invention provides an endotracheal tube fixer for prone ventilation. Compared with the existing endotracheal tube fixer, the endotracheal tube fixer is provided with a head support mechanism, a tube fixing mechanism and a neck support mechanism when in use. When in use, the user can provide support and fixation for the patient's head through the head support mechanism, and adjust the position and angle of the patient's neck through the neck support mechanism so that it can better fit the endotracheal tube. At the same time, the user can fix the tube position through the tube fixing mechanism. Through the combination of the three, better support and fixation can be provided to the patient, and the stability of the endotracheal tube when it is fixed. In addition, the distance, height and angle among the head support mechanism, the tube fixing mechanism and the neck support mechanism can be adjusted and fixed, so that the device as a whole can be suitable for patients of different body shapes when in use, thereby increasing the scope of application of the device as a whole when in use and improving the practicality of the device as a whole.
