Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, and more specifically, to a preventive pillow. Background Art

[0002] In recent years, with the increase of cardiovascular and cerebrovascular diseases and malignant tumors, coupled with the aging of the population, the number of bedridden patients has been on the rise. If the care is not done properly, pressure injuries are very likely to occur, causing great pain to patients and their families. Pressure injury refers to the long-term compression of local tissues under the action of multiple factors such as pressure, shear force, friction, and moisture, causing persistent ischemia, hypoxia, and malnutrition, resulting in local damage to the skin and subcutaneous tissues. It can be manifested as skin integrity damage or open wounds, usually occurring in places where tissues are compressed, shear force or bone protrusions. The high-risk population for pressure injuries is mainly paraplegic, long-term bedridden, and comatose patients, of course, including some non-paraplegic, non-comatose long-term bedridden patients. For example, some elderly people who have the ability to move independently after being bedridden can also cause pressure sores if they are unwilling to move after being bedridden. Some young people can also develop pressure sores after being bedridden for a long time after lumbar fractures and pelvic fractures.

[0003] The most common sites of pressure injuries vary depending on the body position. The most common sites for supine position are, from top to bottom, mainly the headrest, scapula, sacrum and coccyx, ischial tuberosity, and heels. The most common sites for side-lying position are the ears, shoulder joints, hip joints, knee joints, and ankle joints. The most common sites for prone position are the forehead, anterior chest, anterior superior iliac spine, knees, and feet.

[0004] In the related art, the products for preventing pressure injuries are mostly triangular pillows for maintaining the sideways position, hollow ring-shaped cotton pads or inflatable devices for the buttocks and other parts, mainly to prevent injuries to the buttocks, hips and shoulder joints. However, it is difficult to prevent injuries to the ears and head and other head and facial skin, and long-term use can easily increase the discomfort of the patient's shoulder and neck, which is not conducive to the patient's daily use or treatment and rehabilitation, and may even increase pain.

[0031] The preventive pillow 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0032] Reference Figure 1-Figure 3 As shown, the preventive pillow 100 according to the embodiment of the present invention may include: a first pillow part 10 and a second pillow part 20 .

[0033] Specifically, the second pillow portion 20 is connected to the first pillow portion 10 through the flexible region 30, and the flexible region 30 is deformable so that the first pillow portion 10 and the second pillow portion 20 have a stacked state and a spliced ​​state. In the stacked state, the first pillow portion 10 and the second pillow portion 20 are connected in the thickness direction (for example, Figure 2 In the spliced ​​state, the first pillow portion 10 and the second pillow portion 20 are spliced ​​and placed in the same layer. The first pillow portion 10 is provided with a first avoidance recess, or the second pillow portion 20 is provided with a second avoidance recess 21, or the first pillow portion 10 is provided with a first avoidance recess and the second pillow portion 20 is provided with a second avoidance recess 21.

[0034] When the first pillow 10 and the second pillow 20 are in a stacked state, the first pillow 10 and the second pillow 20 are stacked in the thickness direction. At this time, the height of the first pillow 10 and the second pillow 20 in the stacking direction can match the amplitude of the cervical spine when the patient is in a side-lying position, which can effectively relieve the pressure on the patient's auricle and acromion, and improve the patient's comfort. In some embodiments where the second pillow 20 is provided with a second avoidance recess 21, the second avoidance recess 21 can avoid the position of the patient's ears when the patient is in a side-lying position, so that the patient can place the ears and part of the face in the second avoidance recess 21, reducing the possibility of pressure damage to the patient's ears and part of the face due to long-term compression by the pillow surface. At the same time, when the patient's head and face have already suffered pressure damage, reducing the contact area between the patient's wound surface and the pillow surface can relieve the existing wound surface, reduce the possibility of secondary damage to the patient's wound surface, and speed up the patient's healing time.

[0035] When the first pillow 10 and the second pillow 20 are in a spliced ​​state, the first pillow 10 and the second pillow 20 are spliced ​​and placed in the same layer. At this time, the height of the first pillow 10 or the second pillow 20 can match the amplitude of the cervical spine when the patient is in a supine position, which can effectively relieve the pressure on the patient's head and acromion, and improve the patient's comfort. In some embodiments where the first pillow 10 is provided with a first avoidance recess or the second pillow 20 is provided with a second avoidance recess 21, the first avoidance recess or the second avoidance recess 21 can avoid the position of the back of the patient's head when the patient is in a supine position, so that the patient can place the back of the head in the first avoidance recess or the second avoidance recess 21, reducing the possibility of the patient's back of the head being compressed by the pillow surface for a long time and causing pressure damage. At the same time, when the patient's head has already suffered pressure damage, reducing the contact area between the patient's wound surface and the pillow surface can relieve the existing wound surface, reduce the possibility of causing secondary damage to the patient's wound surface, and speed up the patient's healing time.

[0036] The first pillow portion 10 and the second pillow portion 20 are connected via a deformable flexible region 30, and the structure is relatively simple. The first pillow portion 10 and the second pillow portion 20 are easy to adjust, and the stacked state and the spliced ​​state are easy to achieve. The patient is more convenient and more comfortable to use.

[0037] According to the preventive pillow 100 of the embodiment of the utility model, the first pillow part 10 and the second pillow part 20 are connected by the flexible area 30, so that the first pillow part 10 and the second pillow part 20 have a stacked state and a spliced ​​state, so that the patient can match the amplitude of the cervical spine when lying on the back and lying on the side, respectively. It can effectively prevent pressure injuries of the head and face, relieve existing wounds, improve the patient's comfort, and reduce the possibility of secondary damage to the patient's wound. At the same time, the preventive pillow 100 has a simple structure, is easy to integrate, and is relatively convenient to use.

[0038] In some embodiments of the present invention, Figure 1-Figure 3As shown, the flexible area 30 connects the surface of the first pillow part 10 along the thickness direction with the surface of the second pillow part 20 along the thickness direction, so that the first pillow part 10 and the second pillow part 20 are less deformed when stacked, which facilitates stacking. Figure 2 The upper surface of the first pillow portion 10 and the upper surface of the second pillow portion 20 are connected.

[0039] In some embodiments of the present invention, Figure 2 As shown, the flexible area 30 includes a detachable structure, and the first pillow portion 10 and the second pillow portion 20 are detachably connected through the detachable structure. After the first pillow portion 10 and the second pillow portion 20 are separated by the detachable structure, the stacking of the first pillow portion 10 and the second pillow portion 20 is not limited by the connection part, so the stacking state of the first pillow portion 10 and the second pillow portion 20 is easier to achieve and more convenient to use. At the same time, the first pillow portion 10 and the second pillow portion 20 can be used for different patients after being separated, which is convenient for increasing the available number when the number of preventive pillows 100 is insufficient. In addition, the detachable connection of the first pillow portion 10 and the second pillow portion 20 makes it easy to separate the first pillow portion 10 and the second pillow portion 20 for separate cleaning when cleaning the preventive pillow 100, making the cleaning of the preventive pillow 100 more convenient and more efficient.

[0040] The detachable structure may include a zipper, a buckle or a Velcro, etc. In some embodiments, the detachable structure includes a zipper, and the zipper extends along the circumference of the joint surface of the first pillow portion 10 and the second pillow portion 20 .

[0041] In other words, the zipper connects the entire circle when the first pillow portion 10 and the second pillow portion 20 are in the spliced ​​state. Figure 1-Figure 3 The upper side, front side, lower side and back side of the preventive pillow 100 are continuously connected by a zipper, so that when the patient rests his head on the flexible area 30, the upper and lower surfaces of the first pillow part 10 and the second pillow part 20 are in a connected state and will not separate, which provides better support for the head.

[0042] When the first pillow part 10 and the second pillow part 20 need to be stacked, the zipper and the corresponding parts of the lower surface and the front and rear sides can be unzipped, and only the connection between the zipper and the corresponding parts of the upper surface can be retained, so that the stacking can be achieved and the first pillow part 10 and the second pillow part are still connected together, which can reduce the possibility of the first pillow part 10 and the second pillow part 20 being separated when used by the patient, and improve the reliability of the preventive pillow 100. In addition, the first pillow part 10 and the second pillow part 20 are better fitted to each other in the stacked state, which is conducive to improving the comfort of the preventive pillow 100.

[0043] In some embodiments where the flexible region 30 includes a detachable structure, the flexible region 30 may also include a shielding member connected to the first pillow portion 10 or the second pillow portion 20 and used to shield the detachable structure, thereby preventing the patient from being hurt by the detachable structure when the patient rests on the flexible region 30 and feeling pain, thereby improving the patient's comfort. For example, the shielding member may be a cloth strip used for shielding.

[0044] In some embodiments of the present invention, Figure 2 As shown, the thickness of the first pillow portion 10 is 7 to 9 cm, which can meet the cervical spine height adaptation requirements of most patients lying on their backs. Of course, for different preventive pillows 100, first pillow portions 10 of different thicknesses can be used, or the same preventive pillow 100 can include multiple first pillow portions 10 of different thicknesses to meet the different height requirements of the cervical spine of different patients.

[0045] The thickness of the second pillow part 20 is 4 to 6 cm. The thickness of the first pillow part 10 is greater than that of the second pillow part 20, so as to facilitate the stacking of the first pillow part 10 and the second pillow part 20. When the first pillow part 10 and the second pillow part 20 are in the stacked state, the height of the preventive pillow 100 can meet the cervical vertebra amplitude requirements of the patient when lying on his side, so as to relieve the pressure of the patient's auricle and acromion, and improve the comfort of the patient when using the preventive pillow 100.

[0046] In some embodiments of the present invention, the first pillow 10 includes latex material, which has high density and elasticity and good air permeability, and is suitable for the patient to rest his head on the first pillow 10 when lying on his back. At the same time, the outer side of the first pillow 10 can be wrapped with cloth such as pure cotton to improve the comfort of the patient's head.

[0047] In some embodiments, the second pillow 20 includes expanded polypropylene (EPP) filling particles, so that the second pillow 20 has a loose structure, which is suitable for the patient to rest the side of the face on the second pillow 20 when lying on the side, thereby reducing the pressure on the patient's face. At the same time, the outer side of the second pillow 20 can be wrapped with a fabric such as modal to improve the comfort of the patient's face.

[0048] In some embodiments, Figure 1 and Figure 3 As shown, the support surface of the first pillow 10 for supporting the head is a continuous surface 11, in other words, the first pillow 10 is not provided with a first avoidance recess. The second pillow 20 is provided with a second avoidance recess 21, and the second avoidance recess 21 penetrates the second pillow 20 along the thickness direction.

[0049] The continuous surface 11 facilitates better support of the patient's head, reduces the pressure on the patient's head, and improves the patient's comfort. The second avoidance recess 21 that runs through the second pillow portion 20 in the thickness direction enables the patient to place the head in the second avoidance recess 21 when lying on the back, and the patient can place the ear in the second avoidance recess 21 when lying on the side, which is convenient for reducing the possibility of pressure injuries on the patient's head and face, or reducing the possibility of secondary damage to the patient's wound surface when the patient's head and face have already suffered pressure injuries, relieving the patient's wound surface, and allowing the patient's head and facial injuries to heal faster. In some embodiments, the second avoidance recess 21 is D-shaped, which is convenient for adapting to the ear area of ​​the patient when lying on the side, so that the patient's ear can be more comfortably placed in the second avoidance recess 21, improving the patient's comfort when using the preventive pillow 100.

[0050] In some embodiments of the present invention, Figure 1-Figure 3 As shown, there are two second pillow portions 20, and the two second pillow portions 20 are respectively connected to the two ends of the length direction of the first pillow portion 10 through the flexible area 30 (for example Figure 1 The preventive pillow 100 is connected to the first pillow portion 10 (left end and right end shown in the figure), so that the preventive pillow 100 can be stacked at both ends of the length direction of the first pillow portion 10, which is convenient for the patient to lie on the side in two directions (for example, lying on the left side or lying on the right side), improves the practicality of the preventive pillow 100, and makes it more convenient for the patient to use. Moreover, in the spliced ​​state, the overall length of the preventive pillow 100 is longer, which is easy to improve the comfort of the patient. In some embodiments, the outer contour of the second pillow portion 20 is a D-shaped shape, wherein the straight edge of the D-shaped shape is connected to the first pillow portion 10 through the flexible region 30, which is convenient for the flexible region 30 to fold, and the D-shaped shape can adapt to the patient's face when lying on the side, so that the second pillow portion 20 can better fit the patient's side face position, improving the patient's comfort.

[0051] In some embodiments where the second pillow portion 20 is two, such as Figure 2 As shown, the length of the second pillow portion 20 is less than or equal to half the length of the first pillow portion 10, so that the two second pillow portions 20 can be stacked with the first pillow portion 10 at the same time, which is convenient for the patient to quickly realize the transition between two side-lying positions (such as left side lying position and right side lying position), thereby improving the practicality of the preventive pillow 100. The length direction of the preventive pillow 100 refers to the left-right direction parallel to the line connecting the two ears of the human body when the patient lies flat.

[0052] A preventive pillow 100 according to a specific embodiment of the present invention is described in detail below with reference to the accompanying drawings. It should be understood that the following description is only an exemplary illustration and cannot be construed as a limitation to the present invention.

[0053] like Figure 1-Figure 3As shown, a preventive pillow 100 according to a specific embodiment of the present invention comprises a first pillow portion 10, a second pillow portion 20 and a flexible area 30. The first pillow portion 10 comprises a continuous surface 11, there are two second pillow portions 20, each of the second pillow portions 20 comprises a D-shaped second avoidance recess 21 penetrating in the thickness direction, and the flexible area 30 comprises a detachable structure and a shielding member.

[0054] The first pillow part 10 is 50 cm long, 35 cm wide and 7 cm high. The first pillow part 10 is filled with natural latex and wrapped with pure cotton material. The second pillow part 20 is D-shaped and 5 cm high. The second pillow part 20 is filled with EPP filling particles and wrapped with modal material. The detachable structure is a zipper, which is an invisible zipper after being covered by a covering member. The two second pillow parts 20 are respectively connected to the left and right ends of the first pillow part 10 through a flexible area 30, and the flexible area 30 connects the upper surface of the first pillow part 10 and the upper surface of the second pillow part 20.

[0055] The first pillow 10 and the second pillow 20 have a stacked state and a spliced ​​state. When the patient turns over, the preventive pillow 100 can be adjusted between the spliced ​​state and the stacked state, so that the height of the patient's head can be adjusted when the patient turns over, which meets the patient's cervical spine amplitude requirements. When the first pillow 10 and the second pillow 20 are in a stacked state, the height of the first pillow 10 and the second pillow 20 can match the amplitude of the patient's cervical spine in the side-lying position, and the second avoidance recess 21 of the second pillow 20 can place the patient's ears, so that there is a gap in the ears, which can effectively relieve the pressure on the patient's auricle and acromion. When the first pillow 10 and the second pillow 20 are in a spliced ​​state, the height of the first pillow 10 can match the amplitude of the patient's cervical spine in the supine position, and the continuous surface 11 can support the patient's head, improving the patient's comfort.

[0056] In addition, the first pillow 10 and the second pillow 20 can be separated. After the invisible zipper is opened, the first pillow 10 and the second pillow 20 can be separated to use the first pillow 10 or the second pillow 20 separately. Then, the second pillow 20 can be used in a supine position, and the back of the patient's head is placed in the second avoidance recess 21 to relieve the pressure on the patient's head. At the same time, the first pillow 10 and the second pillow 20 are detachable, making it more convenient to clean the preventive pillow 100, and facilitating the disassembly and washing of the preventive pillow 100.

[0057] Therefore, the preventive pillow 100 can reduce the possibility of pressure injuries on the patient's head and face, or prevent secondary damage to the patient's wound surface when the patient has already suffered pressure injuries, which is helpful to relieve the pressure on the patient's wound surface and enable the patient to recover faster.

[0058] Other structures and operations of the preventive pillow 100 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
