Description

Technical Field

[0001] This utility model relates to the field of cushion technology, specifically a cushion for cardiovascular care. Background Technology

[0002] Cardiovascular diseases are usually caused by ischemic or hemorrhagic diseases of the heart and peripheral blood vessels due to high blood lipids, thick blood, atherosclerosis, high blood pressure, etc. These diseases can lead to arteriosclerosis, which thickens and hardens the blood vessel walls, narrows or even blocks the lumen, thereby affecting blood flow.

[0003] Cardiovascular patients should not sit for long periods of time and there are certain requirements for their sitting posture. Maintaining the correct sitting posture is crucial for cardiovascular health. To care for cardiovascular patients, a backrest pillow is placed on one side of the patient's chair back to keep the lower back in a natural curve, effectively protect the spine, and reduce pressure on the lumbar nerves.

[0004] However, existing backrests will deform and dent after prolonged use, and the support angle of the backrest will change, resulting in a decrease in the support and care effect. They will be unable to support the sitting posture of cardiovascular patients, thus reducing the care effect for patients and causing harm to them.

[0005] Therefore, a cardiovascular care cushion is proposed. Utility Model Content

To achieve the above objective, this utility model provides the following technical solution: A cardiovascular care cushion includes a fixing plate and a cushion assembly. A second rotating seat is installed on each side of the fixing plate. A positioning assembly is welded to one end of each of the two second rotating seats. Two limiting plates are welded to one side of the fixing plate. A cushion assembly is installed between the two limiting plates via a rotating shaft. A first rotating seat is installed on each side of the cushion assembly. A limiting slide rod is welded to one side of each first rotating seat. Multiple limiting holes are equally spaced on one side of each limiting slide rod. The positioning assembly includes a positioning sleeve. The limiting slide rod is slidably installed inside the positioning sleeve. A second lead screw is threadedly connected inside the positioning sleeve. The second lead screw is installed in conjunction with the limiting holes.

[0007] Preferably, the cushion assembly includes two side plates, and multiple reinforcing rods are welded at equal intervals between the two side plates, and a mesh cushion is fixed between the two side plates.

[0021] 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.

[0022] Example 1: A second rotating seat 10 is installed on each side of the fixed plate 1. A positioning component 11 is welded to one end of each of the two second rotating seats 10. Two limiting plates 6 are welded to one side of the fixed plate 1. A cushion component 5 is installed between the two limiting plates 6 via a rotating shaft. A first rotating seat 8 is installed on each side of the cushion component 5. A limiting slide rod 9 is welded to one side of the first rotating seat 8. Multiple limiting holes 901 are equally spaced on one side of the limiting slide rod 9. The positioning component 11 includes a positioning sleeve 1101. The limiting slide rod 9 is slidably installed inside the positioning sleeve 1101. A second lead screw 1102 is threadedly connected inside the positioning sleeve 1101. The second lead screw 1102 is installed in conjunction with the limiting holes 901.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, since two limiting plates 6 are welded to one side of the fixed plate 1, and a cushion assembly 5 is installed between the two limiting plates 6 via a rotating shaft, the cushion assembly 5 can be flipped, thereby changing the angle between the cushion assembly 5 and the fixed plate 1. Since a first rotating seat 8 is installed on each side of the cushion assembly 5, and a limiting slide rod 9 is welded to one side of the first rotating seat 8, the limiting slide rod 9 is slidably installed inside the positioning sleeve 1101. Since a second lead screw 1102 is threadedly connected inside the positioning sleeve 1101, by rotating the second lead screw 1102, one end of the second lead screw 1102 is pulled out from the limiting hole 901 opened on one side of the limiting slide rod 9, thus flipping the angle of the cushion assembly 5. When the cushion assembly 5 is flipped, the limiting slide rod 9 will slide inside the positioning sleeve 1101. Since the positioning assembly 11 is installed on one side of the fixed plate 1 via the second rotating seat 10, when the cushion assembly 5 is flipped, the angle of the cushion assembly 5 can be changed. After the angle of component 5 changes, the limiting slide rod 9 will drive the second rotating seat 10 and the first rotating seat 8 to rotate, thereby ensuring that the limiting slide rod 9 can slide inside the positioning sleeve 1101. After the angle of the backrest component 5 is adjusted, the second lead screw 1102 is rotated, so that one end of the second lead screw 1102 is inserted into the limiting hole 901 at the designated position, thereby fixing the limiting slide rod 9 inside the positioning sleeve 1101. This allows the backrest component 5 to be rotated at a certain angle for support, ensuring that the angle of the backrest component 5 will not change during use, thus providing long-term and effective back support care for seated patients. This device can provide long-term and effective back support for seated patients, and the support angle will not change with the use time, improving the effectiveness of care. At the same time, the support angle of the backrest can be adjusted according to the patient's wishes, improving the flexibility of the device.

[0024] Example 2: The cushion assembly 5 includes two side plates 502. Multiple reinforcing rods 501 are welded at equal intervals between the two side plates 502. A mesh cushion 503 is fixed between the two side plates 502. Two mounting slots 4 are opened on one side of the fixing plate 1. A support slide rod 3 is fixed inside each of the two mounting slots 4. Springs 7 are respectively sleeved on the outer sides of both ends of the support slide rod 3. A clamping assembly 2 is slidably sleeved on the outer sides of both ends of the support slide rod 3. The clamping assembly 2 includes a slot block 201. A slider 204 is welded to one side of the slot block 201. The slider 204 is slidably sleeved on the outer side of the support slide rod 3. A first lead screw 202 is threadedly connected inside the slot block 201. A pressing plate 205 is installed at one end of the first lead screw 202 through a third rotating seat 203.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, multiple reinforcing rods 501 are welded between the two side plates 502. These reinforcing rods 501 can improve the stability of the device while reducing its weight. A mesh backrest 503 is installed between the two side plates 502. This mesh backrest 503 supports the patient's back while improving breathability, ensuring that the patient's back does not feel stuffy even after prolonged use. The mesh backrest 503 is woven from high-elastic yarn and has advantages such as deformation resistance, scratch resistance, and breathability. When installing the fixing plate 1, multiple clamping components 2 installed on one side of the fixing plate 1 can be respectively clamped onto both sides of the seat back. Since the clamping component 2 includes a slot block 201, one side of the seat back can be inserted into the slot block 201. A slider 204 is welded to one side of 201, and the slider 204 is slidably sleeved on the outside of the support slide rod 3. Springs 7 are sleeved on the outside of both ends of the support slide rod 3. When encountering seat backs of different widths, the slot block 201 can be slid to widen the gap between the two slot blocks 201. Then, the two sides of the seat back are clamped inside the two slot blocks 201. The compression and rebound of the springs 7 can ensure the stability of the slot blocks 201 clamping the two sides of the seat back. By adjusting the gap between the two slot blocks 201, it is possible to install for seat backs of different widths, improving the flexibility of the device installation. Then, by rotating the first lead screw 202, the third rotating seat 203 can be driven to squeeze one side of the seat back, thereby improving the stability of the fixing plate 1 installed on the seat back.

[0026] Working principle: In use, the entire fixing plate 1 is installed on one side of the seat back. The distance between the two slot blocks 201 is adjusted by sliding them. Then, the two sides of the seat back are inserted into the slot blocks 201 respectively. Then, by rotating the first lead screw 202, the pressing plate 205 is driven to press the seat back into the slot blocks 201, thus fixing the entire device to one side of the seat back. Then, the angle of the cushion assembly 5 is adjusted according to the patient's requirements. When the cushion assembly 5 is flipped, the limiting slide rod 9 will slide inside the positioning slide sleeve 1101. Since the positioning assembly 11 is installed on one side of the fixing plate 1 through the second rotating seat 10, when the cushion assembly 5 is flipped, the angle of the cushion assembly 5 is adjusted. After the angle of the cushion assembly 5 changes, the second rotating seat 10 and the first rotating seat 8 will rotate due to the linkage of the limiting slide rod 9, thereby ensuring that the limiting slide rod 9 can slide inside the positioning sleeve 1101. After the angle of the cushion assembly 5 is adjusted, the second lead screw 1102 is rotated so that one end of the second lead screw 1102 is inserted into the limiting hole 901 at the designated position, thereby fixing the limiting slide rod 9 inside the positioning sleeve 1101. This allows the cushion assembly 5 to be rotated at a certain angle for support, ensuring that the angle of the cushion assembly 5 will not change during use, thus providing long-term effective back support care for sitting patients.
