Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tracheal intubation supporting device. Background Art

[0002] At present, the occurrence of ventilator-associated pneumonia (VAP) after tracheal intubation in hospitalized patients is still a topic of discussion and research. How to effectively prevent the occurrence of VAP requires thinking and research. Currently, after the patient's tracheal intubation, the ventilator only has a bracket to fix the ventilator pipeline, and the fixing device for the front part of the patient's oral intubation (which needs to be connected to the ventilator circuit and the closed suction tube) is only used to fix the oral intubation. There is no sufficient and effective elevation. The front end of the oral intubation sags due to gravity, which is easy to cause the accumulation and reflux of airway condensation water, and will also increase the pressure injury problem of the patient's lower lip. At the same time, it will also cause deviation during the patient's movement, affecting the treatment effect.

[0003] Patent publication number CN213158656U discloses a novel multifunctional fixing device for oral intubation, including an intubation fixing block and fixing belts arranged at both ends of the intubation fixing block, and the intubation fixing block is provided with a tracheal hole, a stomach tube hole and a nursing hole. CN217645648U discloses a tracheal intubation reinforcement device for respiratory medical treatment, including a reinforcement baffle, a strap behind the ear, a facial clip cover, a slot, a rotating rod, an anti-slip rubber ring, a fixing sleeve, a bearing and a connecting hinge. However, the above fixing devices are only used to fix the oral intubation tube or trachea, and fix it on the patient's face, which is easy to squeeze the patient and has no effect of lifting the intubation catheter. Utility Model Content

[0004] The purpose of the utility model is to provide a tracheal intubation support device in order to overcome the defects of the above-mentioned prior art, which can effectively raise the front part of the intubation tube in the patient's mouth, eliminate the problem of accumulation of condensed water, effectively prevent the occurrence of VAP, and relieve the pressure on the patient's lips and reduce pressure injuries.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A tracheal cannula support device is used to support a tracheal cannula on the support device, one end of the tracheal cannula is inserted into the patient's oral cavity, and the support device comprises:

[0007] An elastic, size-controllable spherical support body is placed at a certain part of the patient's upper body, and an inflatable cavity is arranged inside the support body;

[0008] A fixing groove located on the upper surface of the spherical support body for placing the endotracheal tube;

[0009] And an inflation valve located on the side wall of the spherical support body for inflation and connected to the inflation cavity.

[0010] Furthermore, the spherical support body can be placed at a certain part of the upper body of the patient, and the support point can be changed according to the change of the patient's body position, thereby playing a supporting role.

[0011] Furthermore, the supporting device also includes fixing belts located on both sides of the fixing groove.

[0012] Furthermore, the fixing belt is connected to the inflation cavity. The fixing belt is located on both sides of the fixing groove. When inflated, the fixing belt stands upright, which plays a certain role in limiting the oral cannula and preventing it from falling off. When the patient is agitated, the two fixing belts can tighten the oral cannula and fix it for a second time.

[0013] Further, the inflation valve is connected to an inflation component, and the inflation component includes:

[0014] An inflation tube detachably connected to the inflation valve;

[0015] An inflatable cylinder connected to the inflatable tube and used for inflating;

[0016] and a valve located on the inflation tube.

[0017] Furthermore, a sealing cover for sealing the inflation valve is provided on one side of the inflation valve. After the spherical support body is inflated, the inflation valve is blocked to prevent the spherical support body from leaking. After the inflation component is inflated, the valve is closed and the inflation tube is separated from the inflation valve to prevent the inflation component from affecting the change of the support point of the spherical support body.

[0018] Furthermore, the spherical support body is provided with a plurality of protrusions for fixing the spherical support body, preventing the spherical support body from deflecting, and increasing the friction between the spherical support body and the patient.

[0019] Furthermore, the tracheal tube includes an oral tube and a condenser tube, which are cross-connected. When working, the oral tube of the tracheal tube is placed in the fixed groove, so that the connection between the oral tube and the condenser tube is higher than the patient's oral cavity and the other end of the condenser tube. This prevents the tracheal tube from pressing the patient's oral cavity due to its own gravity, and also prevents the condenser tube from turning over due to its own gravity, causing the condensed water in the condenser tube to flow back from the condenser tube through the oral tube into the patient's oral cavity, resulting in the occurrence of VAP.

[0020] Furthermore, the fixing groove is in an arc shape.

[0021] Furthermore, the diameter of the fixing groove is larger than the diameter of the oral cannula, and oral cannulas of various sizes can be placed therein.

[0022] Furthermore, a spring sheet is provided in the fixing groove to adapt to oral cannulas of various sizes, reduce deviation, increase stability, and improve patient comfort.

[0023] Furthermore, the spherical support body is made of a light material, is not prone to pressure sores, does not add gravity to the endotracheal tube, can be soaked or wiped for disinfection, and can be reused repeatedly to reduce cross infection.

[0024] Compared with the prior art, the utility model has the following advantages:

[0025] (1) The support device provided by the utility model has the function of lifting the front end of the oral cannula, and provides effective support so that the connection between the oral cannula and the condenser tube is higher than the patient's oral cavity and the other end of the condenser tube. This prevents the tracheal cannula from pressing on the patient's oral cavity due to its own gravity, and also prevents the condenser tube from turning over due to its own gravity, causing the condensed water in the condenser tube to flow back into the patient's oral cavity from the condenser tube through the oral cannula, resulting in the occurrence of VAP. The support device can prevent the oral cannula from falling out or being lifted ineffectively, eradicate the problem of condensed water accumulation, prevent condensed water from flowing back into the patient's trachea, and effectively prevent the occurrence of VAP.

[0026] (2) The main body of the support device provided by the utility model is a spherical support body, which can be placed on a certain part of the upper body of the patient, reducing the pressure on the face when it is placed on the patient's face, reducing the problem of pressure injury on the patient's face, and the spherical support body can change the support point according to the change of the patient's body position, thereby playing a supporting role. It can be suitable for patients who use the head of the bed to change the height or change the body position.

[0027] (3) The support device provided by the utility model is provided with an inflation valve and an inflation component, so that the size of the sphere can be adjusted for patients with different body shapes, different intubations, and different body positions to achieve the most appropriate support height and support effect. When not in use, the air can be released to flatten the sphere for easy storage.

[0028] (4) The support device provided by the utility model fixes the endotracheal tube through the fixing groove and the fixing belt on the spherical support body, and contacts a certain part of the patient's upper body. Compared with the existing support devices, it is less likely to cause traction for agitated conscious patients and has stronger stability. BRIEF DESCRIPTION OF THE DRAWINGS
