Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an improved airway opening and maintenance device for gastroscopy. Background Technology

[0002] Gastroscopy is a common medical examination method. By inserting a gastroscope through the mouth into the esophagus, stomach, and duodenum, doctors can directly observe the internal condition of these areas, which is of great significance for diagnosing upper gastrointestinal diseases. During gastroscopy, especially after the patient is anesthetized, maintaining the correct body position is crucial to ensuring a clear airway and a smooth examination.

[0003] Currently, patients are typically positioned on their side during gastroscopy. However, anesthesia can cause muscle relaxation, including in the neck, making it difficult for patients to maintain a proper airway opening posture. Some patients may not tilt their heads back enough, leading to airway compression and increasing the risk of suffocation. In certain surgical situations, a specific head-tilt / chin-lift posture is also required for better surgical visualization or ease of manipulation. Traditionally, multiple pillows may be used to elevate the head, but this method is difficult to precisely adjust in height and angle and has poor stability. Furthermore, while neck braces offer some stability, traditional neck braces are bulky and their Velcro fastening becomes unreliable after prolonged use. Once worn, they also prevent adjustment of the head tilt angle and do not provide sufficient operating space around the neck. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 An improved airway patency maintenance device for gastroscopy includes a support 1, which comprises two side support sections 11 and a lower support section 15 connecting the two side support sections 11. The support 1 serves as the basic structure of the device. The side support sections 11 provide lateral support to the entire head from both sides, ensuring the device is stably positioned on both sides of the patient's neck. The lower support section 15 acts as a connection and support from below, resting against the upper chest directly below the patient's neck to distribute pressure on the neck and maintain the overall stability of the device.

[0027] A chin rest 2 is installed between the two side support sections 11. A knob 23 is located on each side of the chin rest 2. The chin rest 2 is mounted on the side support section 11 via the knobs 23. Rotating the knobs 23 adjusts the angle of the chin rest 2. During gastroscopy, rotating the knobs 23 changes the angle of the chin rest 2, precisely adjusting the degree of chin tilt to open the airway and reduce the risk of suffocation due to insufficient head tilt during anesthesia.

[0028] A cervical support 3 is also installed behind the two side support sections 11. The cervical support 3 is used to wrap around and fix the entire device around the patient's neck. The cervical support 3 wraps around the back of the patient's head and, together with the side support sections 11 and the lower support section 15, wraps the entire device around and fixes it around the patient's neck. This forms a complete and stable support system for the device around the patient's neck, preventing the device from shifting or falling off during use. It ensures that the device can continuously provide stable support and head tilt adjustment function for the patient during gastroscopy.

[0029] The chin support 2 includes an outer support 21, which is made of a rigid material, specifically a high-strength plastic. As the main frame of the chin support 2, the outer support 21 provides primary mechanical support. During gastroscopy, the patient's chin rests on it, and its high strength allows it to stably support the weight of the chin and the additional pressure exerted by adjusting the head tilt angle. The outer support 21 has a first inner padding layer 22 made of a soft material, such as silicone or sponge, which is skin-friendly and soft. Its soft texture effectively distributes the pressure on the chin, preventing the rigid outer support 21 from directly compressing the chin and causing discomfort or even indentations. Simultaneously, the elasticity of the soft material adapts to the shape and contour of different patients' chins, providing personalized support and further enhancing patient comfort when wearing the device.

[0030] A mounting hole 12 is provided on one side support section 11. The first engaging tooth 24 on the knob 23 is installed in the mounting hole 12. A second spring button 16 is also provided on the side support section 11. The spring button is used to control whether the knob 23 can rotate. The knob 23 is provided with the first engaging tooth 24. The mounting hole 12 provides space for the installation and positioning of the first engaging tooth 24 on the knob 23. The first engaging tooth 24 serves as the connection and locking component between the knob 23 and the mounting hole 12 of the side support section 11. When it is necessary to adjust the angle of the chin rest 2, the medical staff presses the second spring button 16. The spring inside the button is compressed, causing the first engaging tooth 24 to disengage from the mounting hole 12. At this time, the knob 23 can rotate freely, making it convenient for the medical staff to adjust the angle.

[0031] The neck support 3 includes an outer neck support 32, which is made of a rigid material, such as high-strength plastic. Inside the outer neck support 32, there is a second inner padding layer 31, which is made of a soft material, such as soft silicone, sponge, or other skin-friendly and elastic materials.

[0032] A slot 14 and a first spring button 13 are also provided on one side support section 11, and a second engaging tooth 34 is provided on the insertion strip 33. The slot 14 is a groove-shaped structure with a specific shape and size, whose internal space and shape are adapted to the insertion strip 33, allowing the insertion strip 33 to be smoothly inserted into it. When it is necessary to install or remove the cervical support 3, press the first spring button 13, and the spring inside the button is compressed, causing the slot 14 to disengage from the second engaging tooth 34 on the insertion strip 33. At this time, the insertion strip 33 can be freely inserted or removed from the slot 14, which facilitates the assembly and disassembly of the device by medical staff, and also allows adjustment of the tightness of the cervical support 3.

[0033] The outer neck brace 32 has an insertion strip 33 and a fixing strip 35 on both sides. The fixing strip 35 mainly serves to fix the outer neck brace 32 to the side support strip, so that the rear neck brace 3 and the side support section 11 form a stable integrated structure on that side. The fixing strip 35 is made of fabric and can change the angle of the rear neck brace during the installation of the rear neck brace 3.

[0034] Working principle: When wearing the device, firstly, by pressing the first spring button 13, the second engaging tooth 34 on the insertion strip 33 in the slot 14 is released, allowing the insertion strip 33 to be removed from the side support section 11. Then, the entire device is worn around the patient's neck, with the chin rest 2 supporting the patient's chin and the lower support section 15 resting against the upper chest directly below the patient's neck. The back neck support 3 is then wrapped around the back of the patient's head. Finally, the insertion strip 33 is reinserted into the slot 14, and the second engaging tooth 34 on the insertion strip 33 engages with the engaging tooth inside the first spring button 13, thus completing the wearing of the device. To adjust the patient's chin tilt angle, the knob 23 is rotated to increase the angle of the chin rest 2. To decrease the chin tilt angle, the second spring button 16 is pressed to release the first engaging tooth 24, and then the knob 23 is rotated to decrease the chin tilt angle. This results in a lighter, more adjustable fit and adjustable head tilt angle for the patient.
