Description

Technical Field

[0001] This utility model relates to the field of pressure injury prevention air cushion technology, and more specifically, to a pressure injury prevention suspension air cushion for use in intensive care units. Background Technology

[0002] ICU, or Intensive Care Unit, also known as a comprehensive treatment room, provides simultaneous treatment, nursing care, and rehabilitation. It offers isolation facilities and equipment for critically ill or comatose patients, providing optimal care, comprehensive treatment, integrated medical and nursing care, early postoperative rehabilitation, joint care, and exercise therapy.

[0003] Prolonged lying or forced lying position in the ICU can lead to pressure on local tissues, resulting in pressure injuries and pressure sores. To avoid this, pressure-resistant air mattresses are usually used to effectively reduce the occurrence of pressure injuries. In practice, the pressure-resistant air mattress is first placed on the hospital bed, and then the patient lies on it. However, existing pressure-resistant air mattresses lack corresponding fixation methods, and the size of the air mattress may not match the size of the hospital bed. When medical staff raise the hospital bed, the air mattress is prone to sliding, which is not conducive to the treatment of the patient.

[0004] In view of this, we propose a pressure injury-preventing suspension air cushion for use in intensive care units. Utility Model Content

[0025] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A pressure-injury-preventing air cushion for intensive care units includes a base layer 1, an air cushion body 2 on the upper side of the base layer 1, and fixing strips 3 fixedly installed on both sides of the base layer 1. Mounting boxes 4 are fixedly installed on the upper side of each of the two sets of fixing strips 3. Two sets of winding rollers 7 are rotatably installed inside the mounting boxes 4. A first strap 5 is wound around the outer side of each of the two sets of winding rollers 7. The first strap 5 movably passes through the mounting boxes 4 and extends to the outside. A second strap 6 is fixedly installed on the outer part of the first strap 5 located outside the mounting boxes 4. The winding rollers 7 are movable. A connecting plate 8 is fixedly connected through the mounting box 4. A limiting mechanism for docking the connecting plate 8 is provided on the outside of the mounting box 4. Both the first strap 5 and the second strap 6 are provided with matching male and female buckles on their outer sides. The male buckle can quickly engage with the female buckle, which also improves the convenience of fixing the first strap 5 and the second strap 6. At the same time, the second strap 6 is used in conjunction with the first strap 5. The second strap 6 can be bound to a suitable hole in the hospital bed to limit the first strap 5, thereby improving the stability of the pressure injury prevention air cushion.

[0029] Specifically, the limiting mechanism includes a movable block 11 located on the outside of the mounting box 4. Two sets of latches 13 are provided on the lower side of the movable block 11. Multiple sets of latches 14 are fixedly provided on the inner side of each set of latches 13. Multiple sets of slots for engaging the latches 14 are provided on the outer side of the connecting plate 8. When the latches 13 are in contact with the connecting plate 8, the latches 14 can be driven into the slots, thereby fixing the connecting plate 8 and fixing the length of the first strap 5.

[0030] Furthermore, an installation cylinder 9 is fixedly installed on the upper side of the fixing strip 3. A movable rod 10 is movably inserted into the inner side of the installation cylinder 9. The movable rod 10 movably passes through the installation cylinder 9 and extends to the outside. The outer end of the movable rod 10 is fixedly connected to the movable block 11 on the outer side of the installation cylinder 9. A spring 12 is installed inside the installation cylinder 9. One end of the spring 12 is connected to the installation cylinder 9, and the other end of the spring 12 is connected to the movable rod 10. The spring 12 does not deform in its initial state. When the first strap 5 is used to fix the pressure-resistant air cushion, the movable block 11 is moved to cause the latch 13 to separate from the connecting plate 8. When the movable block 11 moves, it can cause the movable rod 10 to move and stretch the spring 12, causing the spring 12 to deform. After the length of the first strap 5 is adjusted, the movable block 11 is released. At this time, the elastic potential energy of the spring 12 is released, which can cause the latch 13 to re-fit the connecting plate 8, thereby facilitating the fixing of the connecting plate 8 and improving the ease of adjustment of the first strap 5.

[0031] It is worth noting that a coil spring 15 is sleeved on the outside of the take-up roller 7. One end of the coil spring 15 is connected to the take-up roller 7, and the other end of the coil spring 15 is connected to the mounting box 4. The coil spring 15 does not deform in its initial state. When the first strap 5 is used, pulling the first strap 5 can drive the take-up roller 7 to rotate. When the take-up tube 7 rotates, it can stretch the coil spring 15, causing the coil spring 15 to deform. In this way, when the first strap 5 is untied from the hospital bed, the elastic potential energy of the coil spring 15 can be released to drive the take-up roller 7 to rotate automatically to rewind the first strap 5, thereby improving the convenience of storing the first strap 5.

[0032] It is worth noting that a gripping groove 16 is provided through the outer side of the movable block 11. The gripping groove 16 makes it convenient for medical staff to pull the movable block 11, thus improving ease of use.

[0033] In addition, multiple sets of anti-slip protrusions 17 are fixedly installed on the lower side of the bottom layer 1. All sets of anti-slip protrusions 17 are made of soft material. When the anti-pressure injury air cushion is laid on the hospital bed, the multiple sets of anti-slip protrusions 17 come into contact with the hospital bed or mattress, thereby increasing the friction between the anti-pressure injury air cushion and the hospital bed or mattress, and further improving the stability of the anti-pressure injury air cushion in use.

[0034] It must be noted that a positioning bolt 18 is provided on the outside of the mounting cylinder 9. The positioning bolt 18 is threaded through the mounting cylinder 9 and extends to the inside. By tightening the positioning bolt 18 towards the inside of the mounting cylinder 9, the positioning bolt 18 abuts against the movable rod 10, thereby fixing the movable rod 10 and the movable block 11. This prevents the bayonet 13 from separating from the connecting plate 8 when the pressure-resistant air cushion is in use, and further ensures the stability of the pressure-resistant air cushion in use.

[0035] Working principle: First, place the pressure-resistant air cushion in a suitable position on the hospital bed. Then, move the movable block 11 upward to separate the latch 13 from the connecting plate 8. When the movable block 11 moves, it drives the movable rod 10 to move and stretches the spring 12. Then, the first strap 5 can be pulled to a suitable length. Then, release the movable block 11. At this time, the rebound force of the spring 12 can drive the latch 13 to fit against the connecting plate 8, thereby facilitating the fixation of the length of the first strap 5. Then, the first strap 5 can be tied to the outside of the hospital bed, thereby achieving the fixation of the pressure-resistant air cushion.
