Thus, the phrases "in one embodiment", "in some other embodiments", "in some other embodiments", etc., which appear at different places in this specification, do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0047] In order to illustrate the technical solution of the present application, a description is given below in conjunction with specific drawings and embodiments.

[0048] Long-term bed rest and long-term surgery make it impossible for patients to change their body positions on their own. The skin tissues on the bony protrusions (such as the forehead, cheeks and mandible in the prone position, and the sacrum and coccyx in the supine position) are under pressure for a long time, resulting in blood circulation disorders, local continuous ischemia, hypoxia, and malnutrition, which lead to damage and necrosis of the skin and subcutaneous tissues, thus forming pressure sores. Therefore, the body position pad is an indispensable surgical auxiliary tool to alleviate the occurrence of pressure sores caused by long surgery or long-term bed rest.

[0049] In the related art, the area of ​​the positioning cushion is often fixed, and the supporting area of ​​the positioning cushion for the patient's body parts is also fixed when in use. Therefore, the supporting area of ​​the positioning cushion for the patient's body parts cannot be dynamically adjusted according to the different body parts of the patient, resulting in poor use effect.

[0050] In order to solve the above problems, the present application provides a positioning pad 100, which can dynamically adjust the supporting area of ​​the positioning pad 100 for the patient according to the different parts of the patient's use, and has a better use effect.

[0051] Please refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of a positioning pad 100 in one embodiment of the present application. Figure 2 yes Figure 1 The partial structural stereogram of the body positioning pad 100 is shown. Figure 3 yes Figure 2 The exploded structural diagram of the positioning pad 100 shown in FIG. Figure 4 yes Figure 2 The top view of the body positioning pad 100 is shown. Figure 5 yes Figure 4 The cross-sectional view of the body positioning pad 100 along the MM direction is shown. Figure 6 yes Figure 5 A schematic structural diagram of the airbag 21 in the lifting assembly 20 is shown.

[0052] An embodiment of the present application provides a positioning pad 100, comprising at least two cushion pads 10, wherein the cushion pads 10 are used to support a body part of a patient along a first direction, wherein all cushion pads 10 are distributed and the orthographic projections of any two cushion pads 10 on a plane perpendicular to the first direction do not completely overlap.

[0053] Please refer to Figure 4 and Figure 5 , the first direction can be Figure 5 The direction indicated by the arrow A in the middle, the first direction may be parallel to the thickness direction of the position pad 100 in actual use, the first direction may be the direction from the cushion pad 10 to the patient's body part, and the plane perpendicular to the first direction may be Figure 4 The plane on which the view lies.

[0054] For example, when the buffer pad 10 is placed on a horizontal plane, the first direction may be a vertically upward direction, that is, the first direction may be a direction opposite to the direction of gravity, and a plane perpendicular to the first direction is a horizontal plane.

[0055] The orthographic projections of any two buffer pads 10 on the plane perpendicular to the first direction do not completely overlap, that is, the orthographic projections of any two buffer pads 10 on the plane perpendicular to the first direction do not completely overlap or do not overlap at all.

[0056] The cushion pad 10 may include a first cushion pad 11, a second cushion pad 12, a third cushion pad 13 and a fourth cushion pad 14, which may be used to support the patient's body parts along a first direction, and the orthographic projections of any two of the first cushion pad 11, the second cushion pad 12, the third cushion pad 13 and the fourth cushion pad 14 on a plane perpendicular to the first direction do not completely overlap. The cushion pad 10 may be made of hydrogel, silica gel, jelly glue, polyurethane glue, modified epoxy glue, modified silane and sponge.

[0057] All the cushion pads 10 may be laid flat in the same plane perpendicular to the first direction. Alternatively, to adapt to the shape of the body part, all the cushion pads 10 may be laid flat in at least two mutually parallel planes, and each plane is perpendicular to the first direction.

[0058] All the cushions 10 may be arranged along an annular path, a linear path or other paths. For example, all the cushions 10 may be arranged along a circular path or a rectangular path. Alternatively, all the cushions 10 may be arranged along a straight path or a curved path.

[0059] For example, when a patient is undergoing prone surgery, the positioning pad 100 can be used as a facial positioning pillow for the patient. At this time, part of the cushion pad 10 can be removed so that the entire positioning pad 100 forms an internal hollow structure. The internal hollow structure can accommodate the patient's facial eyes, mouth, nose, and oxygen mask, etc. The number of cushion pads 10 can also be selected according to the size of the patient's face, thereby dynamically adjusting the support area of ​​the positioning pad 100 for the patient's face.

[0060] As can be seen from the above, the positioning pad 100 provided in the embodiment of the present application includes at least two cushion pads 10, and the cushion pads 10 are used to support the patient's body parts along a first direction. All the cushion pads 10 are distributed, and the orthographic projections of any two cushion pads 10 on the plane perpendicular to the first direction do not completely overlap. Therefore, the number of cushion pads 10 can be dynamically adjusted according to the different body parts of the patient, thereby dynamically adjusting the supporting area of ​​the positioning pad 100 for the patient's body parts, and the use effect is better.

[0061] In the present embodiment, the material of the cushion pad 10 is hydrogel, which has good stretchability, viscoelasticity, skin affinity and certain air permeability, can effectively relieve pressure, and has a certain effect in preventing the occurrence of pressure sores.

[0062] In this embodiment, the cushion pad 10 includes a first cushion pad 11 and a second cushion pad 12. The first cushion pad 11 is provided with a first limiting hole 111. The axial direction of the first limiting hole 111 is parallel to the first direction, and the second cushion pad 12 is located inside the first limiting hole 111. In this way, the position of the second cushion pad 12 relative to the first cushion pad 11 is conveniently limited in the radial direction of the first limiting hole 111 by the first limiting hole 111, thereby preventing the first cushion pad 11 and the second cushion pad 12 from relatively moving in a large range in the radial direction of the first limiting hole 111 when the first cushion pad 11 and the second cushion pad 12 are used to support the patient's body parts along the first direction.

[0063] It can be understood that in actual use, the first cushion 11 and the second cushion 12 can be placed together on a carrier (such as a hospital bed) to prevent the second cushion 12 from moving relative to the first cushion 11 in a direction opposite to the first direction.

[0064] Alternatively, the first limiting hole 111 is configured as a tapered hole, and along the first direction, the aperture of the first limiting hole 111 gradually increases, and the side wall surface of the second buffer pad 12 is arranged to fit the inner wall surface of the first limiting hole 111. In this way, the second buffer pad 12 can be prevented from moving relative to the first buffer pad 11 in a direction opposite to the first direction.

[0065] Please refer to Figure 7 , Figure 7 yes Figure 2 The schematic diagram of the structure of the second cushion pad 12 in the body positioning cushion 100 is shown. Similarly, the cushion pad 10 includes a third cushion pad 13, the second cushion pad 12 is provided with a second limiting hole 121, the axial direction of the second limiting hole 121 is parallel to the first direction, and the third cushion pad 13 is located inside the second limiting hole 121. Such a configuration facilitates the position of the third cushion pad 13 relative to the second cushion pad 12 to be limited by the second limiting hole 121, thereby avoiding a large range of relative movement of the second cushion pad 12 and the third cushion pad 13 in the radial direction of the second limiting hole 121 when the second cushion pad 12 and the third cushion pad 13 are used to support the patient's body parts along the first direction.

[0066] It can be understood that in actual use, the second cushion 12 and the third cushion 13 can be placed together on a carrier (such as a hospital bed) to prevent the third cushion 13 from moving relative to the second cushion 12 in a direction opposite to the first direction.

[0067] Alternatively, the second limiting hole 121 is configured as a tapered hole, and along the first direction, the aperture of the second limiting hole 121 gradually increases, and the side wall surface of the third buffer pad 13 is arranged in close contact with the inner wall surface of the second limiting hole 121. In this way, the third buffer pad 13 can be prevented from moving relative to the second buffer pad 12 in a direction opposite to the first direction.

[0068] In order to prevent the third cushion 13 and the fourth cushion 14 from relatively moving in a large range when the third cushion 13 and the fourth cushion 14 are used to support the patient's body part along the first direction, the cushion 10 includes the fourth cushion 14, the third cushion 13 is provided with a third limiting hole 131, the axial direction of the third limiting hole 131 is parallel to the first direction, and the fourth cushion 14 is located inside the third limiting hole 131. In this way, the position of the fourth cushion 14 relative to the third cushion 13 is conveniently limited by the third limiting hole 131, so as to prevent the third cushion 13 and the fourth cushion 14 from relatively moving in a large range in the radial direction of the third limiting hole 131 when the third cushion 13 and the fourth cushion 14 are used to support the patient's body part along the first direction.

[0069] It can be understood that in actual use, the third cushion 13 and the fourth cushion 14 can be placed together on a carrier (such as a hospital bed) to prevent the fourth cushion 14 from moving relative to the third cushion 13 in a direction opposite to the first direction.

[0070] Alternatively, the third limiting hole 131 is configured as a tapered hole, and along the first direction, the diameter of the third limiting hole 131 gradually increases, and the side wall surface of the fourth buffer pad 14 is arranged to fit the inner wall surface of the third limiting hole 131. In this way, the fourth buffer pad 14 can be prevented from moving relative to the third buffer pad 13 in a direction opposite to the first direction.

[0071] For example, when a patient is undergoing prone surgery, the positioning pad 100 can be used as a facial positioning pillow for the patient. In this case, the fourth cushion pad 14 can be removed so that the entire positioning pad 100 forms an internal hollow structure. The internal hollow structure can accommodate the patient's facial eyes, mouth, nose, and oxygen mask, etc. The number of cushion pads 10 can also be selected according to the size of the patient's face, thereby dynamically adjusting the support area of ​​the positioning pad 100 for the patient's face.

[0072] For example, if the patient's face area is small, the second cushion 12 and the third cushion 13 can be used to support the patient's face along the first direction. For example, if the patient's face area is large, the first cushion 11 and the second cushion 12 can be used to support the patient's face along the first direction.

[0073] In the related art, clinicians reported that patients who have undergone long (sometimes up to ten hours) complex surgery and long-term bed rest still have pressure sores due to prolonged pressure on the bony protrusions. At the same time, some doctors have tried to slightly move the patient during surgery to change the contact point between the patient and the position pad 100, so that the contact surface can obtain blood supply and delay the occurrence of pressure sores. However, this method is currently mostly manually operated by nursing staff, which is inconvenient during the operation.

[0074] Most traditional positioning pads are inflatable. The position of the positioning pad 100 in contact with the patient's body parts is equipped with a cushioning structure of cushioning cotton or soft pads or soft particles to buffer the pressure and avoid the occurrence of pressure sores. However, the contact area between this type of positioning pad 100 and the patient's body parts is fixed. Although there is support from the cushioning structure, when undergoing complex and time-consuming surgery or lying in bed for a long time, the skin at the same position is under pressure for too long and there is still a risk of pressure sores. Therefore, it is necessary to be able to change the structure of the pressure part during surgery.

[0075] To solve the above problems, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the buffer pad 10 is connected to a lifting assembly 20, and the lifting assembly 20 is used to drive the buffer pad 10 to move back and forth along a first direction.

[0076] By adopting the above scheme, the lifting assembly 20 can be used to drive the cushion pad 10 to move back and forth along the first direction as needed, so as to dynamically adjust the contact area between the cushion pad 10 and the patient's body part and the pressure of the cushion pad 10 on the patient's body part, thereby preventing the skin of the same body part from being pressed for too long and causing pressure sores when the patient undergoes complex and time-consuming surgery or stays in bed for a long time.

[0077] The lifting component 20 includes an air bag 21 and an air pump 22 connected to the air bag 21; or, the lifting component 20 includes a mechanical lifting platform.

[0078] In this embodiment, the lifting assembly 20 includes an airbag 21 and an air pump 22 connected to the airbag 21. The airbag 21 can be inflated and deflated by the air pump 22, so that the airbag 21 drives the cushion 10 to move back and forth along the first direction. The airbag 21 and the cushion 10 can be bonded together.

[0079] It can be understood that each buffer pad 10 is connected to a lifting assembly 20, and the lifting assembly 20 can drive the buffer pad 10 to move back and forth along the first direction so that all the buffer pads 10 are laid flat in the same plane perpendicular to the first direction, or all the buffer pads 10 are laid flat in at least two planes parallel to each other, and each plane is perpendicular to the first direction.

[0080] For example, at least two lifting assemblies 20 are provided, and the lifting assemblies 20 and the buffer pads 10 are provided in a one-to-one correspondence.

[0081] Alternatively, one buffer pad is connected to at least two lifting assemblies 20 , and at least two lifting assemblies 20 can adjust parts of the same buffer pad 10 .

[0082] Please refer to Figure 7 and Figure 8 , Figure 8 yes Figure 5 A schematic diagram of the distribution of the airbags 21 in the lifting assembly 20 is shown.

[0083] The cushion 10 is connected to at least two lifting assemblies 20, and all the lifting assemblies 20 are arranged at intervals. In this way, different lifting assemblies 20 can be used to drive different parts of the same cushion 10 to move back and forth along the first direction according to the support needs of the patient's body parts.

[0084] For example, the second buffer pad 12 is connected to four lifting assemblies 20 , and all the lifting assemblies 20 are arranged around the second limiting hole 121 and at intervals along the edge of the second buffer pad 12 .

[0085] It can be understood that the connection structure between the first buffer pad 11 and the lifting assembly 20 , the connection structure between the third buffer pad 13 and the lifting assembly 20 , and the connection structure between the fourth buffer pad 14 and the lifting assembly 20 may be similar to the connection structure between the second buffer pad 12 and the lifting assembly 20 .

[0086] The traditional positioning pad 100 cannot monitor signals such as temperature, pressure, and humidity, and the occurrence of pressure sores is related to factors such as temperature, pressure, and humidity. Therefore, if the changes in facial temperature, pressure, and humidity can be monitored during surgery and early warning prompts can be issued, the occurrence of pressure sores can be effectively prevented.

[0087] Therefore, optionally, the body positioning pad 100 includes a sensing component 40, and the sensing component 40 is used to detect at least one of the temperature of the body part, the humidity of the body part, and the pressure of the body part on the cushion pad 10. In this way, the temperature of the body part, the humidity of the body part, and the pressure data information of the body part on the cushion pad 10 can be monitored in real time according to the sensing component 40, and an early warning prompt can be given, so that it is convenient to use the lifting component 20 to drive the cushion pad 10 to move back and forth in the first direction, and dynamically adjust the contact area between the cushion pad 10 and the patient's body part and the pressure of the cushion pad 10 on the patient's body part.

[0088] It can be understood that the pressure exerted by the body part on the cushion pad 10 and the pressure exerted by the cushion pad 10 on the body part are equal in magnitude and opposite in direction.

[0089] Specifically, the sensing component 40 can be arranged at a certain density (such as 1 mm 2 , 1cm 2 The sensing points can collect feedback information such as pressure, temperature, humidity, etc. of the contact parts.

[0090] Optionally, the sensing component 40 may be composed of different sensors, for example, may include a flexible sensor, and the sensing component 40 is disposed on the cushion 10 and may directly contact the patient's face.

[0091] For example, the sensing component 40 may include a flexible temperature sensor, a flexible humidity sensor, a flexible pressure sensor, and the like.

[0092] Optionally, the position pad 100 includes a flexible circuit board 50, a control module 60, a communication module 70 and a terminal 80, the lifting component 20 and the sensing component 40 are both electrically connected to the flexible circuit board 50, the control module 60 and the communication module 70 are both electrically connected to the flexible circuit board 50, the communication module 70 is in communication connection with the terminal 80, and the terminal 80 records and stores the pressure, temperature, humidity and other data monitored in real time by the sensing component 40, which can be viewed by medical staff at any time. With such a configuration, it is convenient to monitor the temperature of a body part, the humidity of a body part and the pressure data of the cushion pad 10 on the body part in real time through the terminal 80, and the lifting component 20 can be controlled by the terminal 80 to drive the cushion pad 10 to move back and forth along the first direction, thereby making the position pad 100 more convenient and intelligent to use.

[0093] Specifically, the terminal 80 may be a mobile phone or computer of a medical staff, a patient or a patient's family member.

[0094] It is understandable that a switch may also be provided in the control module 60 , and the medical staff may manually control the lifting assembly 20 through the switch to drive the buffer pad 10 to reciprocate along the first direction.

[0095] For example, when the position pad 100 provided in the above embodiment is in use, the sensing component 40 transmits the pressure data of the monitored body part on the cushion pad 10 to the terminal 80 of the medical staff through the flexible circuit board 50 and the communication module 70 in turn, and the medical staff can see the pressure, temperature, humidity and other conditions of the contact part between the patient's body part and the cushion pad 10 in real time on the terminal 80. When the changes in the pressure, temperature, humidity and other conditions of the patient's body part reach the threshold value that may cause pressure sores, the medical staff can receive an early warning signal on the terminal 80. At this time, the medical staff can issue an instruction on the terminal 80 to control the lifting component 20 under the cushion pad 10 of the corresponding body part to move in the direction opposite to the first direction through the control module 60, reduce the contact area between the body part reaching the threshold and the cushion pad 10, and increase the contact area between other body parts and the cushion pad 10, so as to achieve real-time monitoring of pressure, temperature, humidity and the like while changing the body part of the patient in contact with the cushion pad 10.

[0096] Please refer to Figure 1 , Figure 4 and Figure 5 In this embodiment, the positioning cushion 100 includes at least two bases 30, the bases 30 are arranged in one-to-one correspondence with the lifting components 20, the bases 30 are connected to the lifting components 20, and adjacent bases 30 are detachably connected together.

[0097] By adopting the above solution, the position of the lifting assembly 20 can be limited by the base 30 to prevent the adjacent lifting assemblies 20 from moving randomly. At the same time, when the number of buffer pads 10 needs to be increased or decreased, the number of lifting assemblies 20 and bases 30 can be increased at the same time.

[0098] Optionally, adjacent bases 30 can be connected by snap connection, magnetic connection, screw connection or bolt connection. The base 30 and the lifting assembly 20 can be bonded together. The air pump 22 can be installed on the base 30 and connected to the flexible circuit board 50.

[0099] When the position pad 100 provided in the above embodiment is used, taking prone surgery as an example, the position pad 100 used in this embodiment is used as a position pillow for preventing facial pressure sores. A suitable combination of cushion pads 10 is selected according to the size of the patient's face, taking the use of the second cushion pad 12 and the third cushion pad 13 as an example:

[0100] In the initial state, the lifting components 20 are all in the raised state (the airbag 21 is in the inflated state). The patient's face contacts the cushion 10 and the sensing component 40, and the force points where the patient's face contacts the cushion 10 are mainly on the forehead, cheeks on both sides and mandible. The sensing component 40 continuously monitors the pressure, temperature, humidity and other data information of the contact part of the patient's face in real time. The data information is transmitted to the control module 60 and the communication module 70 through the flexible circuit board 50 electrically connected to the sensing component 40, and the data information is transmitted to the terminal 80 through the communication module 70. The pressure, temperature, humidity and other data information of the contact part are displayed in real time on the terminal 80, and the medical staff can view it in real time on the terminal 80.

[0101] When the pressure, temperature, humidity, etc. of the patient's face corresponding to the third cushion pad 13 reaches a threshold value that may cause pressure sores (the system sets a threshold value that may cause pressure sores), the medical staff can receive an early warning signal on the terminal 80. The terminal 80 highlights the value of the corresponding area and issues an early warning signal. After receiving the signal, the medical staff issues an instruction on the terminal 80.

[0102] Specifically, the command on the terminal 80 is transmitted to the control module 60 through the communication module 70, and the control module 60 controls the air pump 22 through the flexible circuit board 50 to deflate the airbag 21 of the lifting assembly 20 corresponding to the third cushion 13. At this time, the area corresponding to the third cushion 13 descends with the airbag 21, and the second cushion 12 continues to support the patient's face. Since the contact area between the area corresponding to the third cushion 13 and the face is reduced, the pressure on the facial skin corresponding to the area is relieved, avoiding the occurrence of pressure sores.

[0103] When the corresponding area of ​​the sensing component 40 on the upper surface of the second cushion 12 detects that the changes in pressure, temperature, humidity, etc. of the face in contact with it reach the threshold value. The terminal 80 highlights the value of the corresponding area and issues a warning signal. After receiving the signal, the medical staff issues an instruction on the terminal 80. The instruction on the terminal 80 is transmitted to the control module 60 through the communication module 70. The control module 60 controls the air pump 22 through the flexible circuit board 50 to deflate the airbag 21 of the lifting component 20 corresponding to the second cushion 12, and at the same time inflate the airbag 21 of the lifting component 20 corresponding to the third cushion 13. At this time, the corresponding area of ​​the second cushion 12 descends with the airbag 21, and the corresponding area of ​​the third cushion 13 rises with the airbag 21. As the support area of ​​the third cushion 13 for the face increases, the contact area between the second cushion 12 and the face decreases, thereby alleviating the pressure on the facial skin in this area and avoiding the occurrence of pressure sores. By analogy, if the skin of a certain area of ​​the face is under pressure for too long and the monitored changes in pressure, temperature, humidity, etc. reach a threshold, the purpose of changing the pressure point on the patient's face is achieved by deflating the airbag 21 of the lifting assembly 20 corresponding to the area and inflating the airbag 21 of the lifting assembly 20 corresponding to the adjacent area.
