Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pressure injury prevention device. Background Art

[0002] Pressure injuries are local injuries of the skin or subcutaneous tissue caused by long-term pressure, including skin pressure injuries and mucosal pressure injuries. They are mainly manifested as local tissue damage or open ulcers, accompanied by pain.

[0003] The main factors that lead to pressure injuries are: first, long-term bed rest, poor blood circulation in the body, and prolonged compression of local tissues leading to ischemia and necrosis; second, malnutrition. Long-term picky eating can lead to a lack of protein and minerals in the body, making it impossible to maintain skin health, and the skin is easily damaged when it is compressed; third, diseases, such as diabetes or kidney failure, can lead to abnormal blood circulation in the body, and prolonged local compression can cause pressure injuries.

[0004] For critically ill patients, lying in bed for a long time can easily lead to pressure injuries. Existing pressure injury prevention devices usually relieve pressure injuries by reducing the pressure on skin tissue or by reducing the contact area between the body and the bed. However, when the patient lies in bed, the part of the body that is under pressure does not change, and long-term pressure on the pressure part is still prone to cause pressure injuries.

The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0037] See also Figure 1-8 The utility model provides a technical solution: a pressure injury prevention device, comprising a bed body, a bed board 1 is arranged on the bed body, two mounting plates 2 are arranged on the bed body, the tops of the two mounting plates 2 are connected to the bed board 1, a sliding plate 3 is arranged between the two mounting plates 2, the sliding plate 3 is slidably matched with the mounting plate 2, and a plurality of upwardly protruding adjustment parts 4 are arranged on the sliding plate 3;

[0038] The multiple adjusting parts 4 are all strip structures arranged parallel to each other, and the extension direction thereof intersects with the sliding direction of the sliding plate 3. The top surface width of the adjusting part 4 is smaller than the bottom surface width, and both side surfaces are inclined surfaces 5 inclined from the upper end to the middle;

[0039] Support blocks 6 are provided on both sides of the adjusting part 4 along the sliding direction. A sliding hole opposite to the support block 6 is opened on the bed board 1. The upper end of the support block 6 slides in the sliding hole, and the lower end abuts against the inclined surface 5 of the adjusting part 4.

[0040] The bed board 1 is provided with a pushing component for pushing the sliding board 3 to slide.

[0041] The bed board 1 is laid flat on the bed body and fixedly connected to the bed body. A guardrail 20 for preventing the patient from falling is fixedly connected to the bed board 1. The mounting plates 2 are located on both sides of the bed board 1 in the length direction and are fixedly connected to the bottom of the bed board 1. The two mounting plates 2 are arranged in parallel. The two mounting plates 2 and the bed board 1 together form a plate-like structure similar to the shape of a letter π. The sliding plate 3 is located between the two mounting plates 2. Two sliding parts are respectively arranged on both sides of the sliding plate 3 in the length direction. The sliding plate 3 is slidably matched with the mounting plate 2 through the sliding parts. By pushing the sliding plate 3, the sliding part can slide along the length direction of the mounting plate 2.

[0042] The sliding plate 3 is integrally connected with a plurality of upwardly protruding adjusting parts 4, each of which is in a strip-shaped structure, and each of which is parallel to each other. The extending directions of each of the adjusting parts 4 intersect with the sliding direction of the sliding plate 3, and the width of the top surface of the adjusting part 4 is smaller than the width of the bottom surface, and both side surfaces are inclined surfaces 5 inclined from the upper end to the middle, and the cross section of the adjusting part 4 is in a trapezoidal shape. By pushing the sliding plate 3, the adjusting part 4 can slide along the length direction of the mounting plate 2;

[0043] The lower ends of the support blocks 6 arranged on both sides of the adjustment part 4 abut against the two inclined surfaces 5 of the adjustment part 4. The support blocks 6 are long strip structures. A sliding hole adapted to the shape and size of the support blocks 6 is opened on the bed board 1. The upper ends of the support blocks 6 are located in the sliding holes and slide in cooperation with the sliding holes. By moving the adjustment part 4, the inclined surfaces 5 of the adjustment part 4 will squeeze and push the support blocks 6 to slide upward along the sliding holes.

[0044] The pushing component is arranged on one side of the bed board 1 in the width direction, and is used to push the sliding plate 3 to slide along the length direction of the mounting plate 2 .

[0045] The extending direction of the adjusting portion 4 is perpendicular to the sliding direction of the sliding plate 3 (the perpendicular design is that when the sliding distance of the sliding plate 3 is the same, the inclined surface 5 of the adjusting portion 4 pushes the supporting block 6 to slide upward to a greater extent).

[0046] Among them, the cross-section of the adjusting part 4 is an isosceles trapezoidal shape, and the two support blocks 6 are symmetrically arranged on both sides of the adjusting part 4, that is, the positions where the lower ends of the two support blocks 6 are against the two sides of the adjusting part 4 are in the same horizontal plane (through the above design, when the sliding distance of the sliding plate 3 to the left and right is the same, the two support blocks 6 slide upward by the same distance).

[0047] Before use, a mattress 19 is laid on the bed board 1 to increase the patient's comfort, and then the bed is moved to the nursing room and the position of the bed is adjusted so that the end of the bed board 1 away from the pushing assembly is against the wall.

[0048] When in use, the patient is transferred to the bed with a stretcher, and the patient's position is adjusted so that the patient lies flat on the mattress 19. Then, the pushing assembly is adjusted so that the sliding plate 3 slides along the side wall of the mounting plate 2 toward the wall, thereby driving the adjusting portion 4 to slide toward the wall. During the sliding process of the adjusting portion 4, the inclined surface 5 on the adjusting portion 4 away from the pushing assembly will squeeze and push the supporting block 6 to slide upward along the sliding hole, and gradually replace the support of the bed board 1 for the patient's body during the upward sliding process. When the lower end of the supporting block 6 moves to the top platform of the adjusting portion 4, the patient's gravity will cause the supporting block 6 to be tightly pressed against the supporting platform of the adjusting portion 4, thereby forming a simple fixation of the supporting block 6.

[0049] The pushing assembly is adjusted in the opposite direction, and the sliding plate 3 slides away from the wall, thereby driving the adjusting part 4 to slide away from the wall. During the sliding process of the adjusting part 4, the support block 6 that has extended upwardly from the bed board 1 gradually slides downward and returns to its original state under the movement of the adjusting part 4 in the opposite direction. The pushing assembly is continued to be adjusted in the opposite direction, and the inclined surface 5 on the adjusting part 4 close to the pushing assembly will squeeze and push the support block 6 to slide upward along the sliding hole. During the upward sliding process, the support block 6 on the adjusting part 4 close to the pushing assembly replaces the original support block 6 extending upwardly from the bed board 1 to support the patient's body, thereby changing the supporting position. Until the lower end of the support block 6 close to the pushing assembly moves to the top platform of the adjusting part 4, the support block 6 is fixed, and the change of the supporting position is realized.

[0050] Similarly to the above, the pushing assembly may be adjusted first so that the sliding plate 3 slides along the side wall of the mounting plate 2 away from the wall, and then the pushing assembly may be adjusted in the reverse direction to switch the supporting position.

[0051] The technical solution provided by the utility model controls the sliding plate 3 to slide back and forth along the side wall of the mounting plate 2 by pushing the component, and the two inclined surfaces 5 of the adjusting portion 4 will respectively periodically squeeze and push the supporting block 6 to slide upward. When the sliding direction of the sliding plate 3 changes, the supporting part of the body by the supporting block 6 will also change. The change of the supporting part can effectively avoid pressure damage caused by the unchanged pressure part and the pressure part being under pressure for a long time.

[0052] In this embodiment, a roller 7 is provided at the lower end of the support block 6 , and the wheel surface of the roller 7 abuts against the inclined surface 5 of the adjusting portion 4 .

[0053] A plurality of rollers 7 are installed at the lower end of the support block 6 , and the wheel surfaces of the plurality of rollers 7 are all in contact with the inclined surface 5 of the adjustment portion 4 . When the support block 6 slides upward, the rollers 7 will roll along the inclined surface 5 .

[0054] By using the roller 7 as a supporting structure between the support block 6 and the inclined surface 5, the support block 6 is pressed against the inclined surface 5 through the roller 7. When the support block 6 slides along the sliding hole, the roller 7 will roll along the inclined surface 5. The roller 7 can reduce the resistance encountered by the inclined surface 5 of the adjusting part 4 when squeezing and pushing the support block 6.

[0055] In this embodiment, the top of the adjusting portion 4 is a locking platform 8 , and the middle of the locking platform 8 is recessed downward to form a locking groove 9 for engaging the roller 7 .

[0056] The locking platform 8 is arranged parallel to the bed board 1 , and the cross section of the locking groove 9 is in an arc shape.

[0057] By using the locking groove 9 as a limiting structure of the roller 7, when the roller 7 moves along the inclined surface 5 to the locking platform 8 and then engages in the locking groove 9, the position of the roller 7 can be limited. Under the action of the patient's gravity, the roller 7 will be tightly pressed against the bottom of the locking groove 9, making it difficult for the roller 7 to move at will.

[0058] In this embodiment: sliding grooves are provided on opposite sides of the two mounting plates 2, and pulleys 10 are provided on opposite sides of the sliding plate 3. The pulleys 10 are located in the sliding grooves and slideably cooperate with the sliding grooves.

[0059] The sliding part is a pulley 10 , and there are multiple pulleys 10 that are evenly arranged on the side of the sliding plate 3 .

[0060] By using the pulley 10 as a supporting structure for the sliding plate 3 on the mounting plate 2 , when the sliding plate 3 is pushed to move, the pulley 10 rolls along the side wall of the slide groove, and the pulley 10 can reduce the resistance encountered by the sliding plate 3 during the sliding process.

[0061] In this embodiment: the outer sliding sleeve of the support block 6 is provided with a reinforcement sleeve 11 , and the reinforcement sleeve 11 is connected to the bottom of the bed board 1 .

[0062] By using the reinforcement sleeve 11 as a reinforcement structure of the support block 6 , damage to the sliding hole caused by the support block 6 sliding up and down along the sliding hole can be reduced.

[0063] In this embodiment: a limiting plate 12 is arranged on the top of the supporting block 6 , and the limiting plate 12 is located above the bed board 1 .

[0064] The top of the support block 6 is fixedly connected to the bottom surface of the limiting plate 12 , and the support block 6 and the limiting plate 12 together form a T-shaped plate structure.

[0065] The design of the limit plate 12 is that, firstly, by using the limit plate 12 as a limit structure of the support block 6, the top of the support block 6 can be effectively prevented from sliding down out of the sliding hole; secondly, by using the limit plate 12 as a support structure for the human body, it can provide support for the human body and increase the support area, thereby providing a better support effect.

[0066] In this embodiment: the pushing assembly includes a pressure rod 14, one end of which is hinged to the bed board 1, and a push rod 13 is provided on the side wall of the sliding plate 3. One end of the push rod 13 is hinged to the sliding plate 3, and the other end is hinged to the middle of the pressure rod 14.

[0067] The pressure rod 14 is hinged to the bed board 1 through a pin, and the push rod 13 and the sliding plate 3 as well as the push rod 13 and the middle part of the pressure rod 14 are hinged through a pin. The end of the push rod 13 away from the sliding plate 3 is fixedly connected with a handle 15.

[0068] When in use, press the handle 15 downward to make the pressure rod 14 rotate clockwise along the hinge point between the pressure rod 14 and the bed board 1, and push the sliding plate 3 to slide to the left under the transmission action of the push rod 13; pull the handle 15 upward to make the pressure rod 14 rotate counterclockwise along the hinge point between the pressure rod 14 and the bed board 1, and pull the sliding plate 3 to slide to the right under the transmission action of the push rod 13.

[0069] In this embodiment, the bed body includes a support plate 16 and a bracket 17 . The bracket 17 is installed below the support plate 16 . The top of the support plate 16 is connected to the bottom of the mounting plate 2 . The top surface of the support plate 16 abuts against the bottom surface of the sliding plate 3 .

[0070] The bracket 17 is fixedly connected below the support plate 16 , and the top of the support plate 16 is fixedly connected to the bottom of the mounting plate 2 . The support plate 16 and the mounting plate 2 together form a U-shaped plate structure.

[0071] By using the support plate 16 as an auxiliary supporting structure of the sliding plate 3 , an auxiliary supporting effect can be achieved on the sliding plate 3 .

[0072] The four corners of the bottom of the bracket 17 are all provided with moving wheels 21, and the moving wheels 21 are designed to facilitate the movement of the bed.

[0073] In this embodiment, a ball 18 is embedded in the bottom surface of the sliding plate 3 , and the lower end of the ball 18 abuts against the support plate 16 .

[0074] By providing the balls 18 , the resistance of the sliding plate 3 during sliding can be reduced, so that the sliding plate 3 can slide more smoothly.

[0075] In this embodiment: the adjusting portion 4 is a hollow structure.

[0076] By providing the adjustment part 4 with a hollow structure, the weight of the adjustment part 4 can be reduced, thereby reducing the weight of the entire device.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
