Description

Technical Field

[0001] The invention relates to the technical field of digestion aid devices, in particular to a digestion aid device for critically ill patients who are bedridden for a long time. Background Art

[0002] Long-term bedridden critically ill patients often face problems such as indigestion and abdominal distension due to limited physical mobility. The traditional way is to use manual massage to help digestion, but this is very time-consuming and labor-intensive and cannot meet the needs of long-term bedridden critically ill patients.

[0003] After searching, a Chinese patent with the publication number CN219878616U discloses a digestion aid device for long-term bedridden patients with severe abdominal distension, comprising: a medical bed plate, mounting brackets are fixedly installed on both sides of the top of the medical bed plate, two fixed blocks are fixedly installed on the mounting brackets, two slide rails are fixedly installed on the sides of the fixed blocks close to each other on one side, sliders are slidably installed on the slide rails, a massager crossbeam is fixedly installed on the top of the slider, and a massager body is fixedly installed on the bottom of the massager crossbeam. The utility model is provided with fixed blocks, slide rails, sliders, massager crossbeams, and massager bodies, which can effectively solve the problem that the current massage method for such patients is usually manual pressing by nurses, which is not only time-consuming and labor-intensive, but also has low massage efficiency and slow patient recovery speed.

[0004] In the above technology, although the massager body can be moved through the design of structures such as sliders and slide rails to achieve massage of the patient's abdomen, the nurse still needs to hold the handle to push the massager body to move during the massage process, so the nurse will still consume a lot of physical strength during long-term massage. In addition, the massager body can only reciprocate along a straight line during massage, and its movement trajectory is relatively simple. Since the abdomen of the human body is a complex physiological structure containing multiple organs and tissues, a simple linear reciprocating massage cannot fully cover all areas of the abdomen, resulting in poor massage effect, and thus unable to achieve a good digestion-aiding effect;

[0005] To this end, the present invention provides a digestion aid device for critically ill patients who are bedridden for a long time. Summary of the invention

At this time, the second spring 226 will shrink. During the downward movement of the guide block 223, the roller 221 will roll along the surface of the guide block 223, and at the same time drive the connecting arm 220 to move toward the outside of the U-shaped frame 2. When the connecting arm 220 moves, it will drive the limit block 217 to move into the accommodating groove 216, so that the limit block 217 is disengaged from the limit groove 107. At this time, the first spring 218 will shrink. The U-shaped frame 2 can be disassembled smoothly. When the patient's abdomen needs to be massaged, the U-shaped frame 2 is pushed to move to the patient's abdomen position, and then the staff can release the handle 225. At this time, the second spring 226 will rebound and push the connecting plate 224, the slide rod 222 and the guide block 223 to move upward. In the process of the guide block 223 moving upward, the pressure on the first spring 218 disappears, so that it rebounds quickly and pushes the limit block 217 to move, so that the limit block 217 is re-embedded in the limit groove 107, so as to fix the U-shaped frame 2 to facilitate the stability of the U-shaped frame 2 during the subsequent massage process.

Before massaging the patient's abdomen, the U-shaped frame 2 needs to be moved to the patient's abdomen. First, the staff needs to grab the handle 225 and press it downward to move the connecting plate 224, the slide bar 222 and the guide block 223 downward. At this time, the second spring 226 will contract. During the downward movement of the guide block 223, the roller 221 will roll along the surface of the guide block 223, and at the same time drive the connecting arm 220 to move toward the outside of the U-shaped frame 2. When the connecting arm 220 moves, it will drive the limit The positioning block 217 moves into the accommodating groove 216, so that the limiting block 217 is disengaged from the limiting groove 107. At this time, the first spring 218 will shrink, and then push the U-shaped frame 2 to move, so that the U-shaped frame 2 moves to the patient's abdomen. Then the staff can release the handle 225, and the second spring 226 will rebound at this time, and push the connecting plate 224, the slide bar 222 and the guide block 223 to move upward. In the process of the guide block 223 moving upward, the pressure on the first spring 218 disappears, so that it rebounds quickly and pushes the limiting block 217 to move, so that the limiting block 217 is re-embedded in the limiting groove 107, so as to fix the U-shaped frame 2, so as to facilitate the stability of the U-shaped frame 2 during the subsequent massage process;

[0048] When it is necessary to perform a rotational massage on the patient's abdomen, the first gear 303 needs to be meshed with the second gear 209. During operation, the crank 214 is first grasped and rotated to disengage the crank 214 from a slot 213 on the limit plate 212, and then the crank 214 is pushed, thereby driving the motor 205 and the moving block 211 to move along the through slot 210, thereby driving the connecting shaft 206 and the second gear 209 to move, so that the second gear 209 approaches the first gear 303. When the second gear 209 contacts and meshes with the first gear 303, the staff can rotate the crank 214 again to allow the crank 214 to be clamped into the slot 213 on the limit plate 212 near one end of the first gear 303, so as to fix the position of the motor 205. During actual operation, in order to allow the first gear 303 and the second gear 209 to mesh smoothly, when the first gear 303 contacts and the second gear 209, the first gear 303 can be grasped and slightly rotated. The turntable 302 is turned on, thereby driving the first gear 303 to rotate, so that the first gear 303 can smoothly mesh with the second gear 209, and then the motor 205 is turned on, and the motor 205 drives the connecting shaft 206 and the second gear 209 to rotate, thereby driving the first gear 303, the rotating shaft 301 and the turntable 302 to rotate, thereby driving the two massage blocks 309 to rotate, thereby realizing rotational massage of the patient's abdomen, and the motor 205 drives the two massage blocks 309 to rotate clockwise and counterclockwise, thereby improving the massage effect and further helping digestion. When the position of the massage block 309 needs to be adjusted for patients with different body shapes, the knob 307 is turned to drive the bidirectional screw rod 305 to rotate, thereby driving the two first sliders 306 to move in the opposite direction synchronously, and then driving the two massage blocks 309 to move in the opposite direction synchronously, so as to adjust the distance between the two massage blocks 309, and at the same time, the height of the two massage blocks 309 can be adjusted by the first cylinder 308 to adapt to patients with different body shapes;

[0049] When rolling massage is needed for the patient's abdomen, the massage block 309 is first driven upward by the first cylinder 308 to move the massage block 309 away from the patient's abdomen, and the second cylinder 403 is turned on to drive the massage roller 404 to move downward, so that the massage roller 404 contacts the patient's abdomen. Then the staff needs to pull the motor 205 toward one end of the transmission shaft 202 through the crank 214, so that the first bevel gear 207 at one end of the connecting shaft 206 and the second bevel gear 208 at one end of the transmission shaft 202 are meshed together. In actual operation, the staff can grasp the transmission shaft 202 and slightly turn the second gear 209 to slightly rotate the connecting shaft 206 and the first bevel gear 207 so that the first bevel gear 207 and the second bevel gear 208 can be smoothly meshed together. Then the staff needs to turn the crank 214 again to make the crank 214 mesh with the second bevel gear 208. 4 is clamped in the clamping groove 213 on the limiting plate 212 near one end of the transmission shaft 202. At this time, the motor 205 is turned on, and the motor 205 drives the connecting shaft 206 and the first bevel gear 207 to rotate, thereby driving the second bevel gear 208 and the transmission shaft 202 to rotate. At this time, one of the threaded rods 401 will rotate with the transmission shaft 202 under the transmission action of the first synchronous wheel 204 and the first synchronous belt 203, and the two threaded rods 401 will rotate synchronously under the transmission action of the second synchronous wheel 406 and the second synchronous belt 407. Therefore, when the transmission shaft 202 rotates, the two threaded rods 401 will rotate. When the threaded rod 401 rotates, it will drive the second slider 402 to move, thereby driving the second cylinder 403 to move, thereby driving the massage roller 404 to move, so that the massage roller 404 can roll on the patient's abdomen, thereby achieving a massage effect;

[0050] When the patient needs to eat, the handle 225 is pressed to move the connecting plate 224, the slide bar 222 and the guide block 223 downward, thereby driving the limit block 217 to shrink into the accommodating groove 216, so as to remove the U-shaped frame 2, and then the two hydraulic cylinders 104 are opened, and the second bed board 103 is driven to rotate by the hydraulic cylinders 104, so as to drive the patient to sit up gradually, so as to facilitate subsequent eating and help digestion. The groove 106 set on the first bed board 102 can limit the patient's buttocks to prevent the patient from slipping when sitting up. In actual operation, the patient needs the help of the staff when getting up, which further improves the safety of the patient in the process of getting up.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
