Description

Technical Field

[0001] This application relates to the field of medical supplies technology, and in particular to a multifunctional pillow for preventing pressure injuries during prone position therapy. Background Technology

[0002] Guidelines for severe ARDS (Acute Respiratory Distress Syndrome) recommend the prone position to improve oxygenation, with treatment typically lasting up to 16 hours. However, prolonged prone positioning poses several potential risks, with facial pressure injuries being a prominent issue. Even with alternating left and right sides and facial position every 2-4 hours, pressure injuries cannot be completely avoided, increasing patient suffering, hospital costs, and length of stay. Especially when patients are deeply sedated, their sense of sensation and voluntary movement are lost, preventing them from voluntarily adjusting their posture to relieve facial pressure. This results in the face continuously bearing pressure during prolonged contact with the supporting surface, obstructing local blood circulation and significantly increasing the likelihood of pressure injuries. Furthermore, the presence of nasogastric tubes or endotracheal tubes in the mouth or throat alters the force distribution and local environment of the face. These tubes may exert additional pressure and friction on the facial skin, particularly when the patient's head is relatively fixed, making the contact points between these tubes and the skin more prone to indentations, abrasions, and other injuries.

[0003] Current clinically used protective measures, such as gel pillows or dressings, have certain limitations in preventing facial pressure injuries. Gel pillows cannot provide personalized support and pressure relief based on the physiological curves and actual needs of the patient's face, making it difficult to effectively distribute pressure; while dressings mainly serve as isolation and cushioning, and their effect on relieving prolonged and continuous pressure is limited, resulting in poor pressure injury prevention in the treatment of patients with acute respiratory distress syndrome. Utility Model Content

[0004] To address the issue of poor pressure injury prevention during the treatment of patients with acute respiratory distress syndrome, this application provides a multifunctional pillow for pressure injury prevention during prone positioning therapy.

[0005] The multifunctional pillow for preventing pressure injuries during prone position therapy provided in this application adopts the following technical solution:

[0006] A multifunctional pillow for treating pressure injuries in prone position includes multiple pillow bodies arranged radially in a centrally symmetrical manner. The pillow bodies are made of elastic material and have injection ports on their sides for filling them with an expansion medium. The symmetrical center of the multiple pillow bodies has a first pressure relief gap to avoid the patient's auricle, and a second pressure relief gap to avoid the patient's eyes is provided between two adjacent pillow bodies. The pillow body has an arc-shaped top surface.

[0007] Furthermore, a connecting component is provided between two adjacent pillow bodies, and the two bodies are detachably connected via the connecting component.

[0008] Furthermore, the pillow body is provided with four pillow bodies, and the line connecting the center points of the four pillow bodies forms a square. Each pillow body is connected to the other two pillow bodies respectively through two connecting components.

[0009] Furthermore, each of the pillow bodies is equipped with a pressure alarm, and the alarm threshold of the pressure alarm is set to 25-30 mmHg.

[0010] Furthermore, the pillow body is configured with a three-layer structure, wherein the inner layer is made of rubber material, the middle layer is made of latex material, and the outer layer is made of pure cotton fabric, and the outer layer and the middle layer are detachably connected.

[0011] Furthermore, the expansion medium can be a gas or a liquid.

[0012] Furthermore, the connecting component is located at the bottom of the side of the pillow body, and the side of the pillow body away from the connecting component is in contact with the patient.

[0013] Furthermore, the connecting component adopts a zipper fixing method, which includes a first chain belt, a second chain belt, and a zipper pull. The first chain belt and the second chain belt are respectively disposed on the side of two adjacent pillow bodies close to each other, and the zipper pull is used to connect the chain teeth on the first chain belt and the second chain belt.

[0014] Furthermore, the connecting component adopts a snap fastener method, which includes a first snap fastener, a first female snap fastener, a second snap fastener, and a second female snap fastener. The first snap fastener and the first female snap fastener are spaced apart on one of the pillow bodies, and the second snap fastener and the second female snap fastener are spaced apart on the other pillow body. The first snap fastener is connected to the second female snap fastener, and the first female snap fastener is connected to the second snap fastener.

[0015] Furthermore, the connecting component adopts a Velcro fastening method, which includes two connecting straps respectively set on the two pillow bodies. Each connecting strap is provided with a rough side and a hook side, and the rough side on one connecting strap is connected to the hook side on the other connecting strap.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. By setting up multiple pillows arranged radially in a centrally symmetrical manner, and filling each pillow with an expansion medium through an injection port, the pressure points on the patient's head are reasonably adjusted. Furthermore, the first decompression gap between the multiple pillows can avoid the patient's auricle, and the second decompression gap between adjacent pillows can avoid the patient's eyes, thereby effectively reducing pressure injuries caused by prolonged prone positioning. In addition, the top surface of the pillows adopts an arc-shaped design, which can effectively avoid pressure on the gastric tube or endotracheal tube, further reducing the possibility of pressure injuries during the patient's treatment.

[0018] 2. Each pillow can be detachably connected via a connecting component, assembled according to actual needs, and extended to other parts of the body. For example, a single pillow can be placed under the knees or on the instep to prevent toe injuries; two pillows can be used as cushions for patients with wounds. By adjusting the position of the pillows, the second pressure-reducing gap between the two pillows can correspond to the patient's wound location, thereby reducing pressure on the wound.

[0019] 3. By installing a pressure alarm on each pillow, when the pressure alarm detects that the internal pressure of the pillow exceeds the alarm threshold, it can immediately alert the patient or caregiver to change the patient's body, adjust the pressure distribution on the patient's skin, and reduce the occurrence of pressure injuries caused by stress concentration.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] Example 1

[0030] This application discloses a multifunctional pillow for preventing pressure injuries during prone position therapy. (See also...) Figure 1 The prone position treatment anti-pressure injury multifunctional pillow includes multiple pillow bodies 1 arranged radially in a centrally symmetrical manner. Each pillow body 1 is made of elastic material and has an injection port 11 on its side for filling with an expansion medium. A first pressure-relief gap 12 is located at the symmetrical center of each pillow body 1 to avoid the patient's auricle, and a second pressure-relief gap 13 is located between adjacent pillow bodies 1 to avoid the patient's eyes. The top surface of each pillow body 1 has an arc shape. Figure 2 As shown.

[0031] By setting up multiple pillow bodies 1 arranged radially in a centrally symmetrical manner, and filling each pillow body 1 with an expansion medium through an injection port 11, the pressure points on the patient's head are reasonably adjusted. Furthermore, the first pressure-reducing gap 12 between the multiple pillow bodies 1 can avoid obstructing the patient's auricle, and the second pressure-reducing gap 13 between adjacent pillow bodies 1 can avoid obstructing the patient's eyes. Figure 3 As shown, this reduces pressure injuries caused by prolonged prone positioning in patients.

[0032] Specifically, the pillow body 1 consists of a three-layer structure. The inner layer uses thickened rubber material for elastic support, the middle layer uses latex material, which is relatively soft and comfortable, and the outer layer uses pure cotton fabric, which is skin-friendly and absorbent, further improving the comfort of this multifunctional pillow. Furthermore, the outer cotton fabric is fitted onto the pillow body 1, similar to a pillowcase, making it easy to remove and wash, thus avoiding cross-infection. In addition, the connecting component 2 is located on the outer fabric, facilitating manufacturing and processing.

[0033] The expansion medium inside the pillow body 1 can be liquid or gas. In this embodiment, water is used as the expansion medium because it is low in cost, has good fluidity, strong support, and can improve the patient's comfort.

[0034] Furthermore, in its inflated state, the top surface of the pillow 1 is arc-shaped. In this embodiment, the top surface of the pillow 1 is spherical, allowing the first decompression gap 12 and the second decompression gap 13 to be naturally generated. This effectively avoids pressure on the patient's ears and eyes, reducing the pressure on these areas when the patient lies prone for extended periods. Additionally, the spherical design of the pillow 1 prevents pressure on the gastric tube or endotracheal tube, further reducing the possibility of pressure injuries during treatment.

[0035] On the other hand, the injection port 11 protrudes from one side of the pillow body 1. A plug for sealing the injection port 11 is provided at the end of the injection port 11 away from the pillow body 1. In this embodiment, the plug is an internally threaded cylinder, and the end of the injection port 11 is provided with external threads. The plug is threadedly connected to the injection port 11, thereby achieving the sealing of the injection port 11, resulting in good leak-proof performance and high stability. As an alternative embodiment, the injection port 11 can also be configured as a self-sealing port. The injection port 11 section is made of a non-elastic material, and the injection port 11 can be sealed by pinching it flat, which is simple and convenient.

[0036] To enhance the flexibility of the multifunctional pillow of this application, a connecting component 2 is provided between two adjacent pillow bodies 1, allowing for detachable connection between the two pillow bodies 1. This enables assembly according to actual needs and expands its application to other areas. For example, a single pillow body 1 can be placed under the knees or on the instep to prevent pressure sores on the toes; two pillow bodies 1 can be used as cushions for patients with wounds. By adjusting the position of the pillow bodies 1 so that the second pressure-reducing gap 13 between the two pillow bodies aligns with the patient's wound location, pressure on the wound area can be reduced. Figure 4 As shown.

[0037] In the preferred embodiment, four pillow bodies 1 are provided. The line connecting the center points of the four pillow bodies 1 forms a square. The four pillow bodies 1 are arranged radially with central symmetry. Each pillow body 1 is provided with a connecting component 2 on both sides near the central symmetry point. That is, each pillow body 1 is connected to the other two pillow bodies 1 through two connecting components 2 respectively.

[0038] Specifically, refer to Figure 4 The connecting component 2 is fixed by a zipper 21. Specifically, the connecting component 2 includes a first chain strap 211, a second chain strap 212, and a zipper pull 213. The first chain strap 211 and the second chain strap 212 are respectively sewn onto the outer fabric of two different pillow bodies 1. The zipper pull 213 is used to connect the teeth of the first chain strap 211 and the second chain strap 212 sequentially. This zipper 21 fixing method ensures high stability in the connection between the pillow bodies 1, with relatively even and smooth force distribution at the connection point, and convenient assembly and disassembly.

[0039] In actual use, water is injected into each of the four pillow bodies 1 through the injection ports 11, and the amount of water injected into each pillow body 1 is flexibly adjusted to adjust the pressure position on the patient's head to an area with less muscle tissue. Furthermore, the patient's ear is placed into the first decompression slit 12, and the patient's eye is inserted into the second decompression slit 13, thereby reducing pressure injury.

[0040] On the other hand, to avoid abnormal head pressure caused by patient movement or abnormal pressure of the expansion medium inside the pillow 1, which could lead to pressure injuries from prolonged exposure to this position, this embodiment includes a pressure alarm 3 on the side of each pillow 1. The pressure alarm 3 includes a pressure sensor, a processor, and a buzzer. The pressure sensor is connected to the inside of the pillow 1, detecting the internal pressure in real time and transmitting the pressure signal to the processor. When the pressure exceeds a preset threshold, the processor controls the buzzer to activate, alerting the patient or caregiver to adjust the patient's position or the pressure of the expansion medium in each pillow 1. Since the critical pressure for human capillaries is 40-60 mmHg, exceeding this pressure value may cause local ischemia. Clinically, the recommended pressure for the supine / prone position is no more than 30 mmHg. Therefore, the alarm threshold for the pressure alarm 3 is set at 25-30 mmHg. In this embodiment, the alarm threshold of the pressure alarm 3 is set to 30 mmHg, thereby effectively monitoring the pressure on the pillow body 1. By identifying abnormal pressure, it can be determined that there is concentrated pressure on the patient's head, and the patient or staff can be promptly reminded to make adjustments, further reducing the possibility of local pressure injury to the patient's face.

[0041] Example 2

[0042] Compared with Embodiment 1, the connecting component 2 in this embodiment adopts a fastening method using a snap fastener 22. Please refer to [link / reference]. Figure 5 As shown.

[0043] The specific connecting component 2 includes a first male buckle 221, a first female buckle 222, a second male buckle 223, and a second female buckle 224. The first male buckle 221 and the first female buckle 222 are bonded and fixed to the outer fabric of one of the pillow bodies 1 at intervals. The second male buckle 223 and the second female buckle 224 are bonded and fixed to the outer fabric of the other pillow body 1 at intervals, with the two intervals being equal. This allows the first male buckle 221 to be fastened to the second female buckle 224 while the first female buckle 222 is fastened to the second female buckle 223. This makes the connection and disassembly of the pillow bodies 1 convenient and quick.

[0044] Example 3

[0045] Compared with Embodiment 1, the connecting component 2 in Embodiment 3 uses Velcro 23 for fixing. Please refer to... Figure 6 As shown.

[0046] The specific connecting component 2 includes connecting straps sewn and fixed at both ends to the outer fabric of the two pillow bodies 1. Each connecting strap has a nap 231 and a hook 232 fixed on it, and the nap 231 and hook 232 of the two connecting straps are arranged in the same direction, allowing the nap 231 on one connecting strap to connect with the hook 232 on the other connecting strap. This makes the connection and fixing of the pillow bodies 1 extremely convenient. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
