Abstract
Description
Technical Field
[0001] This utility model relates to the field of nursing device technology, specifically a novel cardiovascular auxiliary nursing device. Background Technology
[0002] Daily care for cardiovascular disease is crucial for patients' recovery and quality of life, especially for those requiring prolonged bed rest or with limited mobility. With the advancement of biomedical research, the design of cardiovascular assistive devices increasingly emphasizes the integration of functionality and ergonomics to meet patients' needs in areas such as diet, reading, and rehabilitation training. Existing devices tend towards modular and adjustable structural designs, aiming to provide patients with a more comfortable and convenient user experience. The application of such devices not only helps improve patients' physiological condition but also alleviates the operational burden on caregivers to some extent, reflecting the cross-disciplinary integration of biomedical engineering and clinical nursing.
[0003] Currently, existing cardiovascular assistive nursing devices still have certain limitations. Traditional devices often have a fixed structure and limited adjustment range, making it difficult to adapt to the needs of patients of different body types, especially lacking flexibility in adjusting the height and angle of the table. Furthermore, some devices are inconvenient to store, occupy a large amount of space, and affect the range of movement around the bed. The stability and support strength of the devices are also insufficient, which may lead to wobbling or tilting during use, posing safety hazards. Therefore, there is an urgent need for a new type of nursing device that is compact, easy to adjust, and highly stable to improve patient comfort and nursing efficiency. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a novel cardiovascular auxiliary nursing device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A novel cardiovascular assistive care device, including
[0007] Bed frame;
[0008] The U-shaped plate includes a horizontal section and a vertical section connected to both ends of the horizontal section, the vertical section being rotatably engaged with the bed body;
[0009] The telescopic table is rotatably mounted on the horizontal section, and two support plates are symmetrically rotatably mounted on its side.
[0010] A pin is provided at the end of the vertical section away from the horizontal section, and the bed body is provided with a number of insertion holes along the rotational circumference of the U-shaped plate to engage with the pin.
[0011] When in use, the telescopic table is arranged parallel to the bed surface, and together with the support plate, U-shaped plate and bed surface, it forms a body shape with a wide bottom and a narrow top.
[0012] Preferably, the telescopic table includes a main table and a secondary table, which are slidably coupled. When the secondary table slides toward the bed frame, the length of the telescopic table increases, and vice versa.
[0013] Preferably, the U-shaped plate and the support plate are rotatably arranged on opposite sides of the main table, with the U-shaped plate located on the side of the main table closer to the bed frame and the support plate located on the side of the main table away from the bed frame.
[0014] Preferably, a spring is provided on the vertical section, the end of the spring is fixedly connected to the pin, and the extension and retraction direction of the spring is parallel to the axial direction of the insertion hole.
[0015] Preferably, when the vertical section of the U-shaped board is perpendicular to the bed surface, the telescopic table and the support plate are also perpendicular to the bed surface, and they are all attached to the headboard of the bed frame on the same vertical plane.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. The bottom-wide and top-narrow contour of this utility model conforms to the natural sitting posture of the human body: the legs need to have ample space below, and the upper body operating area needs to be compact and close to the body, reducing friction and pressure between the patient and the device. The height of the telescopic table is level with the waist of the patient when sitting up, so it can be operated without bending over or raising the hands. It is especially suitable for patients with cardiovascular diseases, avoiding discomfort caused by excessive activity and improving the nursing experience.
[0018] 2. This utility model achieves multi-functional adaptation through a triple adjustment structure. The U-shaped plate can be adjusted in angle by using pins and holes. The telescopic table can be extended in length to meet different needs such as dining, reading, and placing ECG monitors. The telescopic table itself can be adjusted in tilt angle by a damping pivot to prevent patients from slipping when placing water cups or books. Multiple adjustment methods adapt to patients of different body types and nursing scenarios, improving ease of use. Attached Figure Description

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0027] Example
[0028] like Figure 1 As shown, a novel cardiovascular assistive nursing device includes a bed frame 1, which includes a bed board and a headboard, and a U-shaped plate 2. The U-shaped plate 2 is made of high-strength aluminum alloy, which is lightweight and has a strong load-bearing capacity. It includes a horizontal section 3 and two vertical sections 4 connected to the two ends of the horizontal section 3. The two vertical sections 4 are symmetrically distributed on both sides of the bed frame 1 and are hinged to the bed frame of the bed frame 1 to ensure that the U-shaped plate 2 can rotate smoothly along the circumference of the side of the bed frame 1. The length of the vertical section 4 is approximately the same as the height of the headboard and slightly greater than the height of the headboard. When the U-shaped plate 2 is set vertically, the vertical section 4 is perpendicular to the bed board and fits against the headboard, while the horizontal section 3 is parallel to the top of the headboard and hangs directly above it to avoid collision with the headboard.
[0029] Preferred, such as Figure 2 , Figure 4 as well as Figure 5As shown, the telescopic table 5 is rotatably mounted on the horizontal section 3. The telescopic table 5 is rotatably mounted on the horizontal section 3 via a damping pivot, which allows the telescopic table 5 to be easily adjusted for use. The telescopic table 5 includes a main table 9 and a secondary table 10. The main table 9 has two parallel slide rails inside, with a U-shaped cross section and built-in rubber pads to reduce sliding noise. The secondary table 10 has a slider at the bottom that matches the slide rails. The two slide together through the slide rail and slider structure. When the secondary table 10 slides towards the bed 1, the length of the telescopic table 5 increases to accommodate the patient's needs for eating and placing large items such as laptops. Conversely, the length of the telescopic table 5 decreases to accommodate small items such as water cups and medicine boxes.
[0030] The telescopic table 5 has two symmetrically rotating support plates 6 on its side. The support plates 6 are connected to the side of the main table 9 away from the bed frame by hinges. When in use, the support plates 6 rotate downwards and their bottoms fit against the bed surface, increasing the support points of the telescopic table 5. When stored, they rotate upwards to a vertical position and fit against the side of the main table 9, reducing space occupation.
[0031] The U-shaped plate 2 and the support plate 6 are respectively rotatably set on opposite sides of the main table 9. The U-shaped plate 2 is located on the side of the main table 9 closer to the headboard of the bed 1, and the support plate 6 is located on the side of the main table 9 away from the headboard of the bed 1, forming a two-sided support structure to improve stability.
[0032] A pin 7 is located at the end of the vertical section 4 away from the horizontal section 3. The pin 7 is a cylindrical metal rod. The bed body 1 has a number of insertion holes 8 along the rotation circumference of the U-shaped plate 2 (i.e., with the hinge axis as the center) that are engaged with the pin 7. There are 6 insertion holes 8, with adjacent insertion holes 8 spaced 15 degrees apart, covering an adjustment range of 0-90°. A spring 11 is provided on the vertical section 4. The end of the spring 11 is fixedly connected to the pin 7. The extension and retraction direction of the spring 11 is parallel to the axial direction of the insertion hole 8.
[0033] When it is necessary to adjust the angle of the U-shaped plate 2, manually pull the pin 7 to overcome the elastic force of the spring 11 and disengage it from the socket 8. After rotating the U-shaped plate 2 to the target angle, release the pin 7. Under the action of the spring 11's restoring force, the pin 7 will automatically insert into the corresponding socket 8, thereby achieving stable fixation of the U-shaped plate 2.
[0034] When in use, the telescopic table 5 is set parallel to the bed surface of the bed frame 1, and it forms a body shape with a wide bottom and a narrow top with the support plate 6, the U-shaped plate 2 and the bed surface of the bed frame 1. When in use, the telescopic table 5 needs to be rotated to a horizontal state parallel to the bed board. At this time, the support plate 6 unfolds and contacts the bed board, and the U-shaped plate 2 is fixed at an angle by the pin 7. The entire device forms a body shape with a wide bottom and a narrow top with the bed surface of the bed frame 1. The bottom near the bed board forms a space for the patient's legs to move due to the unfolding of the support plate 6 and the opening of the angle of the U-shaped plate 2. The top telescopic table 5 fits the upper body position of the patient, which is ergonomic and avoids collision with the device when the patient sits up.
[0035] Preferred, such as Figure 3 As shown, when the vertical section 4 of the U-shaped board 2 is perpendicular to the bed surface, the telescopic table 5 and the support plate 6 are also perpendicular to the bed surface. They are all attached to the headboard of the bed frame 1 and are on the same vertical plane. When the device is not in use, the telescopic table 5 can be shortened, the support plate 6 can be folded upward and attached to the main table 9, and then the telescopic table 5 can be rotated to a vertical state perpendicular to the horizontal section 3. Then, the pin 7 can be pulled to rotate the U-shaped board 2 to a vertical position. At this time, the pin 7 is inserted into the corresponding hole 8 to fix it. The entire device is attached to the headboard to form the same vertical plane, which does not occupy the surrounding space of the bed frame 1 at all, making it convenient for patients to turn over, get out of bed, or for nursing staff to perform bedside operations.
[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
