Description

Technical Field

[0001] This invention relates to the field of nursing devices, and in particular to an anti-gastroesophageal reflux nursing device for use in gastroenterology. Background Technology

[0002] Gastroesophageal reflux disease (GERD) is a condition in which stomach contents abnormally reflux into the esophagus, mouth, and lungs, leading to a series of symptoms, end-organ effects, and complications. It has become one of the most common chronic diseases in my country, with typical symptoms including reflux and heartburn behind the sternum. The persistent discomfort caused by this disease severely impacts patients' quality of life, especially at night, where reflux symptoms are not only more frequent but also longer-lasting. Domestic research data shows that approximately 51% of GERD patients experience nocturnal reflux, directly resulting in a significant decline in sleep quality. From the perspective of pathophysiological mechanisms and nursing interventions, reducing nocturnal reflux through physical methods is a key aspect. Studies have shown that elevating the head of the bed can effectively reduce the time when the esophageal pH is below 4, i.e., reducing the frequency and severity of stomach contents reflux through gravity. Therefore, elevating the head of the bed has been proven to be an effective nursing intervention for GERD.

[0003] Currently, in clinical practice and home care, the main methods for implementing head-up elevation interventions include using bricks or wooden blocks to raise the head of the bed by about 20 centimeters, adjusting the head of the bed with an adjustable mattress, or simply increasing the number of pillows. However, these interventions have significant technical flaws and limitations. In home environments, ordinary household beds are typically bulky and difficult to raise easily. Forcibly raising the head of the bed is not only difficult to perform but also easily leads to decreased bed stability, increasing the risk of patients falling out of bed when turning over. This results in a low percentage of patients actually using head-up elevation methods. Therefore, most patients tend to use a simpler method, namely using two or three pillows to raise their heads. However, this simple method of raising the head violates ergonomic principles, easily causing uneven stress on the neck, shoulder, and back muscles, leading to soreness and discomfort. In severe cases, it may even cause airway compression or obstructed ventilation. Furthermore, this posture does not effectively elevate the esophagus relative to the stomach, failing to achieve the ideal anti-reflux physiological effect. In addition, in a hospital setting, although the head of the bed can be raised with the help of a nursing bed, the height of the head of the bed is often difficult to control precisely, and medical staff are required to assist in the height adjustment, which is not convenient for patients to adjust on their own. Summary of the Invention

[0004] The present invention aims to provide an anti-gastroesophageal reflux nursing device for use in gastroenterology, which solves the problem that existing bed head elevation measures are not convenient for patients to adjust independently.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: an anti-gastroesophageal reflux care device for use in gastroenterology, comprising:

[0006] Support plate;

[0007] A neck pillow, wherein the neck pillow is disposed on one side of the support plate;

[0008] Two rotating plates are rotatably connected to the support plates on both sides of the neck pillow;

[0009] A headrest, which is connected between two rotating plates, with one side of the headrest fitting into the outer surface of the neck pillow;

[0010] A support rod is connected between two rotating plates and is positioned on the side away from the neck pillow.

[0011] A telescopic rod is disposed between the support plate and the drive rod, and the telescopic rod has an arc structure and is located on the movement trajectory of the drive rod;

[0012] A drive assembly for rapidly adjusting the extension of the telescopic rod.

[0013] Preferably, the driving component includes:

[0014] A drive groove is provided on the support plate and communicates with the internal space of the telescopic rod. The two sides of the drive groove penetrate the two side walls of the support plate respectively.

[0015] The first limiting block is disposed in the drive slot;

[0016] Two sealing plates, each of which is slidably and sealingly connected within the drive groove;

[0017] The driving fluid is incompressible and located within the space enclosed by the driving groove, the sealing plate, and the telescopic rod.

[0018] Two drive plates are connected to two sealing plates respectively. One end of each drive plate is located outside the support plate, and a gap is left between the bottom of each drive plate and the drive groove.

[0019] Multiple second limiting blocks are spaced apart on each drive plate. The cross-sectional shape of the first limiting block and all the second limiting blocks is a right-angled triangle. The first limiting block and the second limiting blocks drive the drive plate to deflect through their inclined surfaces and move the drive plate through their right-angled sides.

[0020] With the above setup, the moving drive plate, using the inclined surfaces of the first and second limiting blocks, allows the drive plate to bypass the first limiting block and enter the drive groove by its own elasticity. This causes the sealing plate to push the drive fluid to move, thereby adjusting the extension and retraction of the telescopic rod, thus achieving the adjustment of the headrest's height angle. After adjustment, the right-angled sides of the first and second limiting blocks are used for limiting, thereby locking the headrest's height angle.

[0021] Preferably, each drive plate is rotatably connected to a limiting plate at its bottom, and the bottom of the limiting plate can be flush with the bottom of the support plate after rotation.

[0022] With the above settings, the limiting plate can support the drive plate after the headrest angle is adjusted, thereby preventing the drive plate from moving downwards due to accidental contact, which would cause an unexpected change in the extension of the telescopic rod and affect the anti-gastroesophageal reflux effect.

[0023] Preferably, the support plate is further provided with a fixing plate located at the end of the drive groove, and a return spring is connected between the fixing plate and the sealing plate, the return spring covering the drive plate.

[0024] With the above settings, when reducing the extension and retraction of the telescopic rod, the return spring can quickly reset the sealing plate and provide a buffering effect, reducing the possibility of the patient being startled or accidentally injured due to rapid reset.

[0025] Preferably, the drive plate is provided with a plurality of limiting holes, and a limiting post with one end located outside the limiting hole is inserted into any of the limiting holes.

[0026] With the above settings, the distance the drive plate moves can be preset using the limit post, thereby precisely controlling the extension of the telescopic rod and achieving precise adjustment of the headrest's lifting angle, thus improving the efficiency of headrest angle adjustment.

[0027] Preferably, one end of the two rotating plates is connected to a rotating shaft, the rotating shaft is rotatably connected to the support plate, and the neck pillow has a groove for placing the rotating shaft.

[0028] With the above setup, the rotation axis can maintain the consistency of the movement of the two rotating plates, thereby maintaining the stability of the headrest's movement.

[0029] Preferably, the end of the telescopic rod is provided with an arc-shaped block that cooperates with the support rod.

[0030] With the above setup, the arc block can maintain the contact connection between the support rod and the telescopic rod, which helps to maintain the reliability of the support rod's movement.

[0031] Preferably, the bottom of the support plate is provided with anti-slip texture.

[0032] The above-mentioned design, with its anti-slip texture, helps to maintain the relative position of this care device.

[0033] Compared with existing technologies, the beneficial effects of this solution are:

[0034] 1. This solution, through its unique mechanical transmission and locking structure, successfully solves the problem of patients being unable to independently and conveniently adjust the headrest elevation angle. The solution employs a drive assembly consisting of a drive plate, a sealing plate, incompressible drive fluid, and a telescopic rod. Patients only need to manually push the drive plate; guided by the inclined surfaces of the first and second limiting blocks, the drive plate gradually enters the drive groove, moving the sealing plate and drive fluid, thereby precisely controlling the extension of the telescopic rod and ultimately achieving stepless adjustment of the headrest and upper torso elevation angle. This purely mechanical operation requires no electricity or assistance, allowing patients to independently and promptly make fine adjustments at night based on real-time changes in their reflux symptoms. This greatly improves the convenience of care and patient autonomy, effectively overcoming the inconvenience of traditional methods that require moving the bed or relying on medical staff.

[0035] 2. This approach optimizes the effectiveness and comfort of postural intervention based on human physiological structure and anti-reflux principles. By connecting a headrest between two rotating plates and cooperating with a neck pillow, when the telescopic rod lifts the support rod, causing the rotating plates to rotate around the axis of rotation, the headrest and neck pillow work synergistically to provide overall and balanced support for the patient's head, neck, and shoulders. This not only avoids problems such as neck flexion, uneven muscle stress, and airway compression caused by simply raising the pillow, but more importantly, it achieves overall elevation of the upper torso (not just the head), thereby more effectively raising the position of the esophageal opening relative to the stomach through gravity, significantly enhancing the physiological effect of anti-gastroesophageal reflux, and ensuring nursing effectiveness while improving comfort.

[0036] 3. This solution ensures safety and reliability during use through multiple limiting and stabilizing structures. Firstly, the one-way locking characteristic of the right-angled edges of the first and second limiting blocks in the drive assembly automatically locks after adjustment, preventing the telescopic rod from retracting due to body pressure or turning over, thus reliably maintaining the set elevation angle. Secondly, the limiting plate rotatably connected to the bottom of the drive plate can unfold after adjustment, its bottom flush with the support plate, providing stable support for the drive plate and preventing accidental movement that could alter the headrest angle. Simultaneously, the spaced limiting holes and posts on the drive plate allow patients to preset precise elevation positions as needed, further improving adjustment accuracy and stability after locking. Furthermore, the anti-slip texture on the bottom of the support plate and the arc-shaped block design at the end of the telescopic rod enhance the friction and contact reliability between the device and the bed surface and support rod, effectively reducing the risk of device displacement or tipping over, and ensuring the patient's safety during sleep.

Detailed Implementation

[0044] The present invention will be further described in detail below through specific embodiments:

[0045] Example

[0046] like Figures 1 to 6 As shown, an anti-gastroesophageal reflux care device for use in gastroenterology includes:

[0047] The support plate 1 has anti-slip textures on its bottom. These textures increase the friction between the support plate 1 and the surface it is placed on, thus maintaining the relative position of the support plate 1 and providing a stable resting environment for the patient.

[0048] Neck pillow 2 is made of latex and is located on the left side of support plate 1. A groove is provided in the middle of the lower surface of neck pillow 2 for the rotation shaft 4 to pass through.

[0049] Two rotating plates 3 are connected by a rotating shaft 4 at their left ends. Both ends of the rotating shaft 4 are located outside the neck pillow 2. The rotating shaft 4 drives the two rotating plates 3 to rotate simultaneously, ensuring the smooth lifting and lowering of the headrest 6. Two square support blocks 5 are symmetrically arranged on the rotating shaft 4. The two support blocks 5 are respectively attached to the support plate 1. The rotating shaft 4 is rotatably connected to the two support blocks 5. Each support block 5 is in contact with a groove on the neck pillow 2.

[0050] The headrest 6 is attached between two rotating plates 3. The left side of the headrest 6 has an arc-shaped groove that matches the outer surface of the neck pillow 2.

[0051] Support rod 7 is fixedly connected between two rotating plates 3. Support rod 7 is located on the right side of rotating plate 3 and outside headrest 6.

[0052] A telescopic rod is positioned between the support plate 1 and the drive rod. The telescopic rod has an arc-shaped structure and is located on the movement trajectory of the drive rod. In this embodiment, the telescopic rod consists of a fixed tube 8 and a movable rod 9, both of which are arc-shaped. The fixed tube 8 is fixedly mounted on the support plate 1, and the movable rod 9 is slidably and sealingly connected inside the fixed tube 8. The free end of the movable rod 9 is provided with an arc-shaped block 10 that cooperates with the support rod 7. The arc-shaped block 10 partially encloses the support rod 7, thereby effectively supporting the support rod 7.

[0053] A drive assembly is used to quickly adjust the extension of the telescopic rod. In this embodiment, the drive assembly includes:

[0054] The drive groove 11 is located on the right side of the support plate 1. The drive groove 11 passes through the front and rear side walls of the support plate 1 and is located directly below the fixed tube 8. The drive groove 11 is connected to the internal space of the fixed tube 8.

[0055] Two first limiting blocks 12 are respectively disposed at the ends of the drive groove 11.

[0056] Two sealing plates 13 are slidably and sealingly connected in the drive groove 11, and the two sealing plates 13 are spaced apart on both sides of the fixed pipe 8.

[0057] The driving fluid 14, in this embodiment, is water, but it is not limited to water; it can also be an incompressible liquid such as oil. The driving fluid 14 is incompressible and is located within the space enclosed by the driving groove 11, the two sealing plates 13, the fixed pipe 8, and the moving rod 9.

[0058] Two drive plates 15 are respectively adhered to two sealing plates 13. One end of each drive plate 15 is located outside the support plate 1. A gap is left between the bottom of each drive plate 15 and the drive groove 11. The height of the gap is sufficient to allow the drive plate 15 to deflect and allow the second limiting block 20 to bypass the first limiting block 12. In this embodiment, multiple limiting holes 16 are provided on the side wall of the drive plate 15. A limiting post 17 with one end located outside the limiting hole 16 is inserted into any limiting hole 16. The limiting post 17 adopts a stepped structure. With the help of the limiting post 17, the distance of movement of the drive plate 15 can be preset, thereby precisely controlling the extension of the telescopic rod, thus realizing the precise adjustment of the headrest 6 lifting angle and improving the adjustment efficiency of the headrest 6 angle. Two positioning plates 18 are symmetrically provided at the free end of the bottom of each drive plate 15. A limiting plate 19 is rotatably connected between the two positioning plates 18. After the limiting plate 19 is rotated, its bottom can be flush with the bottom of the support plate 1. Thus, after the headrest 6 is raised and adjusted, the limiting plate 19 can support the drive plate 15, thereby preventing the drive plate 15 from moving downward due to accidental contact, which would cause an unexpected change in the extension of the telescopic rod and affect the anti-gastroesophageal reflux effect.

[0059] Multiple second limiting blocks 20 are spaced apart on each drive plate 15. The cross-sectional shape of the two first limiting blocks 12 and all the second limiting blocks 20 is a right-angled triangle; wherein the inclined surface of the first limiting block 12 faces the outer side of the support plate 1, and the inclined surface of the second limiting block 20 faces the middle of the support plate 1. The first limiting blocks 12 and the second limiting blocks 20 drive the drive plate 15 to deflect through their inclined surfaces, and move the drive plate 15 through their right-angled sides.

[0060] In this embodiment, a fixing plate 21 located at the end of the drive groove 11 is attached to both the front and rear side walls of the support plate 1. A reset spring 22 is connected between the fixing plate 21 and the corresponding sealing plate 13. The reset spring 22 covers the drive plate 15. The reset spring 22 facilitates the reset of the drive plate 15 and also plays a buffering role during the rapid reset process, which helps to maintain the safety of the headrest 6 reset.

[0061] The specific working process of this embodiment is as follows:

[0062] In its initial state, the headrest 6 is in its lowest position. When the patient lies flat on the bed, the head and neck are supported by the headrest 6 and neck pillow 2 respectively. The groove on the lower surface of the neck pillow 2 provides space for the rotating shaft 4, ensuring the flatness and comfort of the device when not in use. When the patient needs to elevate their upper body at night due to reflux symptoms, no assistance is needed; the patient can operate the drive plate 15 located on the side of the support plate 1 with one hand. Specifically, the patient pushes the drive plate 15 inward along the drive groove 11 with their finger. During the movement of the drive plate 15, the inclined surface of the second limiting block 20 slides relative to the inclined surface of the first limiting block 12, generating a force that forces the drive plate 15 to undergo a slight elastic deflection. This allows the second limiting block 20 to smoothly pass over the first limiting block 12 and enter the next level slot, maintaining the continuous movement of the drive plate 15. Each time the drive plate 15 passes a first limit block 12, it advances one gear, and simultaneously the sealing plate 13, which is fixedly connected to it, slides into the drive groove 11, compressing the incompressible drive fluid 14 within the space enclosed by the drive groove 11, the fixed tube 8, and the moving rod 9. Due to the incompressibility of the drive fluid 14, the pressure is rapidly transmitted to the moving rod 9 of the telescopic rod, forcing the moving rod 9 to extend along an arc-shaped trajectory. The arc-shaped block 10 at the end of the moving rod 9 partially encloses the support rod 7. When the moving rod 9 extends, the arc-shaped block 10 abuts against the support rod 7 connected between the two rotating plates 3 and pushes it upward, thereby causing the rotating plate 3 to rotate upward around the rotating axis 4, and the headrest 6 fixed to the rotating plate 3 is raised smoothly accordingly. As the headrest 6 is raised, the neck pillow 2 cooperates with the arc-shaped groove on the left side of the headrest 6 to support the patient's neck, ensuring that the head, neck, and shoulders are evenly stressed, avoiding neck flexion and airway compression caused by simply raising the pillow, thereby effectively raising the position of the esophagus relative to the stomach and achieving an anti-reflux physiological effect. When the patient pushes the drive plate 15 to the desired position, that is, when the headrest 6 reaches the ideal elevation angle, the pushing stops. At this time, the right-angled side of the first limiting block 12 and the right-angled side of the second limiting block 20 engage with each other to form a one-way lock, effectively preventing the drive plate 15 from retracting due to the patient's body pressure or turning over, thereby reliably maintaining the set elevation height.

[0063] To further improve the accuracy and ease of operation of the adjustment, the patient can insert a limiting post 17 into the corresponding limiting hole 16 on the side wall of the drive plate 15 as needed. The maximum movement distance of the drive plate 15 is preset by the limiting post 17, thereby achieving precise control of the headrest 6 elevation angle. After adjustment, the limiting plate 19, which is rotatably connected to the bottom free end of the drive plate 15, can be rotated downwards so that its bottom is flush with the bottom surface of the support plate 1, providing additional support for the drive plate 15 and preventing the headrest 6 angle from changing due to accidental contact. When the patient needs to lower the headrest 6 height or return to a supine position, they only need to manually press down on the drive plate 15 to separate the second limiting block 20 from the first limiting block 12. At this time, the return spring 22 located between the fixed plate 21 and the sealing plate 13 at the end of the drive groove 11 assists the sealing plate 13 to quickly reset, the drive fluid 14 flows back, the moving rod 9 of the telescopic rod retracts, and the headrest 6 descends smoothly. During the entire reset process, the return spring 22 also plays a buffering role, reducing the risk of the patient being startled or accidentally injured due to rapid reset. The entire adjustment process is completed independently by the patient, without the need for electricity or assistance from others. The anti-slip texture on the bottom of the support plate 1 ensures that the device maintains its relative position during use, greatly improving the convenience and safety of nighttime care.
