Description

Technical Field

[0001] This utility model relates to medical preventive devices, specifically, to a facial pressure ulcer prevention device. Background Technology

[0002] Prone ventilation is an effective respiratory support method, especially widely used in patients with acute respiratory distress syndrome (ARDS). However, this position significantly increases the risk of facial pressure ulcers. Current research indicates a higher incidence of facial pressure ulcers in patients undergoing prone ventilation, ranging from 13.8% to 69%, with most being stage I and II pressure ulcers. The mouth, cheekbone, and mandible are the most commonly affected sites.

[0003] Currently, preventing facial pressure ulcers requires comprehensive nursing interventions, including condition assessment, nutritional support, skin care, application of pressure-reducing measures, and psychological support. Pressure-reducing measures include using pressure-reducing tools, regularly changing head position, and protecting the skin. Common pressure-reducing tools include water bags, foam dressings, gel pads, and concave headrests. For example, studies have shown that placing water bags or gel pads under the patient's face and using foam dressings on bony prominences can effectively distribute pressure and reduce localized pressure. Regularly changing head position requires changing the head position every two hours to avoid prolonged localized pressure. This method is simple and easy to implement and does not require additional equipment, but it requires close observation and timely operation by nursing staff. In addition, nursing staff need to regularly check the skin condition and clean the face promptly to prevent the skin from becoming moist due to saliva, secretions, or gastric contents.

[0004] However, the methods currently used in clinical practice still lead to a high incidence of facial pressure ulcers during the prone position, thus affecting disease prognosis. Firstly, due to individual patient differences, some patients may be allergic to the materials of the pressure-relief devices, causing skin irritation or discomfort; furthermore, ordinary support pads are prone to displacement, difficult to adjust, unstable, and poorly tolerated by patients. Secondly, while periodically changing the head position is simple, patients undergoing prolonged prone ventilation may have difficulty cooperating with nursing procedures due to physical discomfort or the effects of sedation. In addition, keeping the skin dry and clean is crucial for preventing pressure ulcers, but in practice, it may be difficult to completely avoid patients' saliva, secretions, or gastric contents, leading to prolonged skin moisture and pressure ulcers.

[0005] Therefore, a new type of facial pressure ulcer prevention device needs to be designed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a facial pressure ulcer prevention device. This device is independent of the hospital bed and has a wide range of applications. This device can fix the patient's head and face, prevent facial pressure, reduce the pressure area on both cheeks, and avoid the occurrence of pressure ulcers.

[0007] To address the aforementioned technical problems, this utility model provides a facial pressure ulcer prevention device, comprising a support mechanism and a prone sleeping panel mechanism; wherein...

[0008] The prone sleeping panel mechanism is adjustablely mounted on top of the support mechanism via a connector. A movable component is provided below the support mechanism so that the prone sleeping panel mechanism can be moved by the support mechanism.

[0009] The prone sleeping panel mechanism includes a panel and a headrest for supporting the patient's head. The headrest is detachably mounted on the panel.

[0042] See Figures 1 to 3 This utility model provides a facial pressure ulcer prevention device, including a support mechanism 3 and a prone sleeping panel mechanism 1. The prone sleeping panel mechanism 1 is adjustablely mounted on top of the support mechanism 3 via a connector 2. A movable component 4 is provided below the support mechanism 3, which can move the prone sleeping panel mechanism 1 through the support mechanism 3. The prone sleeping panel mechanism 1 includes a panel 5 and a headrest 6 that supports the patient's head. The headrest 6 is detachably mounted on the panel 5. A hollow structure 7 is formed in the middle of the panel 5. The middle area of ​​the headrest 6 communicates with the hollow structure 7. A groove structure 8 is formed on the side of the panel 5 near the bed to accommodate the patient's chin. A receiving area 9 is also formed on the panel 5. The receiving area 9 is located on both sides of the hollow structure 7 and is used to place the patient's arms.

[0043] In this invention, a support mechanism 3 serves as the base, and the prone sleeping panel mechanism 1 is mainly used for patients requiring prone ventilation to lie face down. Since patients face one side when prone, their side against the bed surface will inevitably be compressed. Simultaneously, this position causes the endotracheal tube and bite block to touch the bed sheet, which can easily cause local mucosal compression damage. Furthermore, the endotracheal tube is prone to twisting, kinking, and blockage, affecting ventilation and oxygenation, and even increasing the risk of nosocomial infection. Therefore, this application includes a headrest 6 to support the patient's head, a groove mechanism to accommodate the patient's chin, and a receiving area 9 to place the patient's arm. The prone sleeping panel mechanism 1 is adjustablely mounted on the support mechanism 3 via a connector 2, allowing for height adjustment. That is, when the height of the patient's bed does not match the initial height of the prone sleeping panel mechanism 1, it can be adjusted via the connector 2 to match the height of the bed. The openwork structure 7, in conjunction with the headrest 6, allows the patient's face to lie downwards, ensuring that the endotracheal tube and bite block are not contaminated, twisted, kinked, or blocked, and also facilitating the drainage of secretions. Furthermore, the eye, nose, mouth, and endotracheal tubes used on the patient's face are all exposed and not compressed, and can pass through the openwork structure 7 for easy handling.

[0044] It should be noted that, in order to improve the overall stability of the support mechanism 3, the support mechanism 3 can be made of stainless steel, which is easy to clean and disinfect, and has high rigidity.

[0045] The facial pressure ulcer prevention device provided by this utility model can fix the position of the head and face, and prevent pressure ulcers or tube dislodgement caused by the movement of the patient's head. It has both load-bearing and fixing functions, and due to the presence of the connector 2, the device can be used in a variety of hospital beds.

[0046] Further, see Figure 1 In one specific embodiment of this utility model, the support mechanism 3 includes several vertically arranged columns 31. Adjacent columns 31 are connected by a crossbeam 32. The connecting component 2 can be a telescopic cylinder. The columns 31 are connected to the panel 5 through the telescopic cylinder. The columns 31 and the crossbeam 32 cooperate to form a structurally stable support structure. The use of the telescopic cylinder as the connecting component 2 allows for flexible adjustment of the height of the panel 5, facilitating operation.

[0047] Furthermore, the movable component 4 installed below the support mechanism 3 in this utility model includes several casters, each caster being located below the corresponding column 31, and at least one of the casters being equipped with a brake. The casters facilitate the movement of the preventive device by the user, while the brake is designed to prevent displacement from causing injury to the patient after the device is put into use.

[0048] In addition, to ensure the safety of the facial pressure ulcer prevention device provided by this utility model, the device also includes a locking mechanism 10. The support mechanism 3 is connected to the hospital bed through the locking mechanism 10. The locking mechanism 10 includes a first connecting rod 101 and a second connecting rod 102. One end of the first connecting rod 101 is slidably mounted on the column 31 through a first locking member 103. The other end of the first connecting rod 101 is telescopically connected to the second connecting rod 102. The end of the second connecting rod 102 away from the first connecting rod 101 is provided with a clamping component that can clamp the support column of the hospital bed.

[0049] It should be noted that when using this device, after moving it to the preset position and adjusting its height, the first locking member 103 is released, allowing the first connecting rod 101 to slide on the column 31. This allows the device to find the corresponding height position of the support rods and other components on the hospital bed. Then, by adjusting the telescopic length between the first connecting rod 101 and the second connecting rod 102, the clamping assembly can contact the support rods and other components on the hospital bed. Finally, the locking assembly is used to lock the device to the hospital bed. This improves the stability of the device and prevents it from shifting due to external forces, thus ensuring the safety of the patient.

[0050] It should also be noted that, as a specific embodiment of this utility model, a sliding groove can be provided on the column 31, and a protruding structure is provided on the side of the first connecting rod 101 that contacts the column 31. The protruding structure cooperates with the sliding groove and can move along the length direction of the sliding groove. A bolt that can be threadedly connected to the column 31 and the first connecting rod 101 is used as the first locking member 103. When the first connecting rod 101 moves to the required position, the bolt is used to lock the column 31 and the first connecting rod 101.

[0051] Furthermore, the clamping assembly includes a first clamping block 104 fixedly mounted on the second connecting rod 102 and a second clamping block 105 slidably mounted on the second connecting rod 102, with a second locking member 106 provided between the first clamping block 104 and the second clamping block 105.

[0052] It is understood that the clamping assembly can be a separate mechanism that can be rotatably connected to the end of the second connecting rod 102, or it can be a structure directly mounted on the second connecting rod 102, such as... Figure 2 and Figure 3 As shown, in one specific embodiment of the clamping assembly, it includes a first clamping block 104, a second clamping block 105, and a fixing plate. The fixing plate is rotatably mounted on the end of the second connecting rod 102. The first clamping block 104 is fixedly mounted on the fixing plate, and the second clamping block 105 is slidably mounted on the fixing plate. A space is formed between the first clamping block 104 and the second clamping block 105 that can accommodate the bed support rod or bed leg. The distance between the first clamping block 104 and the second clamping block 105 is controlled by using a second locking member 106, thereby clamping the bed support rod or bed leg.

[0053] The clamping assembly is rotatably mounted on the second connecting rod 102 so that it can be clamped and fixed regardless of whether the support rod is a horizontal or vertical rod.

[0054] As a specific embodiment of this utility model, such as Figure 3 As shown, the headrest 6 is a U-shaped pillow, with the opening of the U-shaped pillow facing the groove structure 8. The U-shaped pillow can be made of memory foam. The special shape of the U-shaped pillow can support the patient's head without obstructing the patient's face, and the opening of the U-shaped pillow can leave space for the patient's neck, so as not to cause the patient's breathing difficulties.

[0055] Furthermore, a padding layer 81 is provided on the working surface of the groove structure 8 facing the mandible. The padding layer 81 can be a high-elastic hollow cotton (PP cotton) padding or an inflatable padding. Both can provide certain support for the patient's mandible and can conform to the deformation of the patient's mandible to improve the patient's comfort. Among them, the hollow cotton padding is soft and comfortable and easy to clean and disinfect.

[0056] Furthermore, as a specific embodiment of this utility model, both the headrest 6 and the cushion layer 81 can be detachably mounted on the panel 5 using Velcro. This facilitates easy replacement of the headrest and cushion layer 81, ensuring the cleanliness of the device and simplifying operation, thus reducing the operator's workload. Additionally, a protective cover can be provided over the headrest 6 and cushion layer 81. This protective cover is removable, washable, disinfectable, and reusable, improving environmental friendliness.

[0057] Further, see Figure 1 As a specific embodiment of this utility model, the accommodating area 9 includes a lower plate 91 and an upper contact surface 92. An elastic member 93 is provided between the lower plate 91 and the upper contact surface 92. When the patient's arm applies pressure to the upper contact surface 92, the upper surface of the elastic member 93 can form a space to accommodate the patient's arm.

[0058] As a preferred embodiment, the elastic element 93 can be memory foam, which can deform according to the pressure applied from above. The upper base surface can be soft cotton cloth, while the lower plate 91 is a hard board material such as a wooden board. In this way, when the patient places his arm in the receiving area 9, the memory foam will deform reasonably according to the downward pressure applied by the arm, thereby improving the patient's comfort.

[0059] Alternatively, grooves that can accommodate the arm can be directly provided on both sides of panel 5. This is to prevent the patient's arm from moving around and touching the tubing or medical devices.

[0060] Alternatively, as another implementation of the receiving area, recesses can be directly provided on both sides of the panel for placing the arm. Airbags can be placed in these recesses to increase comfort.

[0061] Furthermore, as a specific embodiment of this utility model, an observation element 33 and a fixing element 34 are also provided on the support mechanism 3. The observation element 33 is rotatably mounted on the support mechanism 3 to observe the patient's facial condition, and the fixing element 34 is provided on the support mechanism 3 to fix the medical tubing. Wherein, for example... Figure 1 As shown, the observation component 33 can be a mirror, which allows medical staff to observe the face of a patient in a prone position. The fixing component 34 can be a hook, which facilitates the fixing of various tubes such as ventilator tubing, negative pressure tubing, and gastric tube.

[0062] Specifically, the following describes the usage process of the facial pressure ulcer prevention device provided by this utility model:

[0063] First, after the device is pushed to the required position by the moving component 4, the height of the support mechanism 3 is adjusted by the telescopic cylinder according to the height of the head of the hospital bed, so that the prone sleeping panel mechanism 1 matches the height of the head of the hospital bed, and the casters are locked by the brake component.

[0064] Next, the bolts serving as the first locking element 103 are loosened, allowing the first connecting rod 101 to move on the column 31 of the support mechanism 3 to adjust the height of the first connecting rod 101. Then, the extension and retraction between the first connecting rod 101 and the second connecting rod 102 are adjusted so that the locking assembly can lock the support rod or bed leg of the hospital bed.

[0065] Then, the memory foam is made into a U-shaped pillow and a hollow cotton pad, which are fixed to the panel 5 with double-sided Velcro. Move the patient's head forward so that the patient's face is facing down and the face is placed on the memory foam U-shaped pillow. The chin is placed in the groove structure 8 on the panel 5 and in contact with the pad. The upper limbs are placed in the receiving area 9 above the panel 5, which can appropriately restrain the arms.

[0066] Medical staff can use the rotatable mirror 33 on the support mechanism 3 to observe whether the patient's eyes, nose and lips are under pressure, observe the position of the endotracheal tube, closed suction tube, gastric tube and negative pressure tube, tidy up the ventilator tubing, extend the tubing out of the hollow structure 7 and hang it on the hook 34 set on the support mechanism 3 as a fixing element.

[0067] The facial pressure ulcer prevention device provided by this utility model has a simple structure, wide applicability, and simple operation. It can fix the patient's head and face, prevent facial pressure, reduce the pressure area on both cheeks, and avoid the occurrence of pressure ulcers.
