Description

Technical Field

[0001] The present invention relates to the technical field of medical tools, and particularly to a medical head and neck pillow device. Background Art

[0002] In modern medical surgery scenarios, the positioning of patients' body positions is crucial, especially the support of the head and neck. The general medical pillows used in traditional operating rooms are mostly ordinary sponge pillows, and these traditional pillows have many drawbacks: on the one hand, they cannot accurately fix the head and neck positions of patients according to personal body types. In surgeries involving the brain, neck, and maxillofacial regions, especially when more precise requirements are placed on the head and neck positions, even a slight displacement may increase the surgical risk; on the other hand, the comfort is poor. During long surgical procedures, patients are in an anesthetized state, and local compression for too long is likely to cause pressure sores on the head and neck. In addition, the temperature in the operating room is relatively low, and long-term hypothermia can easily lead to normal metabolic functions of the patient's body, delay the process of drugs acting in the body, and even cause symptoms such as arrhythmia. In severe cases, it will threaten life safety. Therefore, the present invention provides a medical head and neck pillow device to meet the needs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a medical head and neck pillow device. By setting a limiting component, the height of the cervical region can be adjusted, thereby adapting to the body types of different patients, thus improving the applicable range of this medical head and neck pillow. By adjusting the height of the cervical region, the adaptation effect between the patient's cervical vertebrae and this medical head and neck pillow can also be improved, thereby improving the comfort of the patient and the support effect of the head and neck pillow on the patient, ensuring that the patient's head will not show unstable phenomena during the surgical process. In addition, the limiting component can provide warmth for the patient, so that the patient will not have the phenomenon of too low body temperature during long surgical procedures, improving the surgical success rate and ensuring the safety of the patient. Through the above settings, the problems of poor comfort and small applicable range of the current medical head and neck pillows can be solved.

[0004] To solve the above technical problems, the present invention provides the following technical solutions: A medical head and neck pillow device, comprising a rubber support pad. On one side of the top of the rubber support pad, an occipital region is installed. At the middle position of the top of the rubber support pad, a cervical region is installed. On the other side of the top of the rubber support pad, a shoulder and back region is installed. The occipital region has a downwardly concave arc-shaped contour, and a circular groove is opened at the middle position of the occipital region. The cervical region has an upwardly convex arc-shaped contour. The shoulder and back region has a downwardly inclined slope; a limiting component, which is used for supporting and limiting the patient's head and neck, and is connected to the rubber support pad.

[0005] Optionally, the limiting component includes an inner skeleton inserted through the rubber support pad. A blower base is inserted at the bottom of the inner skeleton. A placement cavity that matches the contour of the inner skeleton is formed on the rubber support pad. An airbag limiting frame is fixedly connected to the inner skeleton at the position corresponding to the cervical region of the rubber support pad. The cross-sectional contour of the inner skeleton is a corrugated structure.

[0006] Optionally, an occipital support frame is fixedly connected to the inner skeleton at the position corresponding to the occipital region of the rubber support pad. The occipital support frame is a segmented sheet structure, and the middle position of the occipital support frame is hollowed out. The occipital support frame corresponds to the position of the circular groove on the occipital region.

[0007] Optionally, expansion plates are symmetrically installed at the top of the airbag limiting frame. The thickness of the expansion plates is less than that of the airbag limiting frame, and there is a gap between the two expansion plates. Weakening grooves are formed on the expansion plates. A support airbag that matches the size of the airbag limiting frame is placed inside the airbag limiting frame.

[0008] Optionally, an air duct mounting plate is fixedly connected to one side of the blower base. A first heating pipe and a second heating pipe are installed on the air duct mounting plate. The second heating pipe is symmetrically installed on both sides of the first heating pipe. A shoulder and back support plate is fixedly connected to the other side of the blower base. Air outlet holes are formed on the shoulder and back support plate.

[0009] Optionally, a side sealing plate is fixedly connected to one side of the inner skeleton. A bottom plate is fixedly connected to the bottom of the side sealing plate. A splicing plate with a "ji" - shaped contour is fixedly connected to one side of the bottom plate. A positioning plate that matches the contour of the bottom plate is fixedly connected to the top of the blower base. An insertion plate corresponding to the position of the splicing plate is installed on the top of the blower base, and the insertion plate is inserted into the "ji" - shaped contour of the splicing plate.

[0010] Optionally, a first insertion cylinder is fixedly connected to the bottom of the airbag limiting frame. A second insertion cylinder corresponding to the position of the first insertion cylinder is fixedly connected to the top of the blower base. An adaptation groove is formed at the bottom of the first insertion cylinder. An adaptation block that matches the contour of the adaptation groove is fixedly connected to the top of the second insertion cylinder.

[0011] Optionally, an airbag inflation channel that communicates with the first heating pipe is formed on the blower base, and one end of the airbag inflation channel extends to the position of the second insertion cylinder.

[0012] Optionally, a communication cavity and a heating channel that communicate with the second heating pipe are formed on the air duct mounting plate. The communication cavity communicates with the placement cavity, and the heating channel extends into the shoulder and back support plate.

[0013] Optionally, a fixed baffle is installed on the side of the inner skeleton away from the side sealing plate. The fixed baffle and the inner skeleton are fixed by a threaded adjustment knob. A gas flow adjustment disc is rotatably connected to the fixed baffle. The gas flow adjustment disc and the fixed baffle are both provided with a first adjustment hole and a second adjustment hole.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting the limit component, the height of the cervical vertebra area can be adjusted, so as to adapt to the body types of different patients, thereby improving the applicable range of the medical head and neck pillow. By adjusting the height of the cervical vertebra area, the matching effect between the patient's cervical vertebra and the medical head and neck pillow can also be improved, thereby improving the comfort of the patient and the supporting effect of the head and neck pillow on the patient, ensuring that the patient's head will not be unstable during the operation. In addition, the limit component can keep the patient warm, so that the patient will not have a phenomenon of hypothermia during the long operation, improving the success rate of the operation and ensuring the safety of the patient.

[0015] By setting the rubber support pad, the occipital region of the rubber support pad has a downwardly concave arc-shaped contour. In this way, not only can the occipital bone be wrapped and limited by the arc-shaped contour of the occipital region when the patient lies on the rubber support pad, but also under the action of gravity, the patient's head will sink into the circular groove in the middle of the occipital region, thereby further wrapping and limiting the patient's head by means of the circular groove, improving the stability and comfort of the patient's head; the cervical vertebra area at the middle position of the rubber support pad has an upwardly convex arc-shaped contour, so that when the patient lies on the rubber support pad, the cervical vertebra position of the patient can be lifted upward by the cervical vertebra area, so that the cervical vertebra area can fill the gap between the head and the cervical vertebra when the patient lies flat, improving the comfort of the patient's cervical vertebra position and ensuring that the patient will not shake due to poor comfort during the operation; the shoulder and back area on the rubber support pad has a downwardly inclined slope. The purpose of this setting is to make the shoulder and back area smoothly support the patient's shoulder and back when the patient lies on the surface of the rubber support pad, and then transition to a flat operating bed, thereby improving the comfort of the patient's shoulder and back.

[0016] By setting the inner skeleton, since the material of the inner skeleton is hard plastic, this setting is to plastically shape the overall contour of the rubber support pad by means of the inner skeleton, so as to ensure that the rubber support pad will not deform during long-term use. The occipital bone support frame can support the occipital bone of the patient, so as to prevent the head from sinking too much into the circular groove in the middle of the occipital region when the patient lies at the position of the circular groove in the occipital region, thereby causing discomfort to the patient. While ensuring that the occipital region can wrap and limit the occipital bone of the patient, it prevents the patient's head from feeling uncomfortable due to excessive depression.

[0017] By setting up the supporting airbag, when the operator fills the first heating pipe with warm air, the warm air will eventually enter the supporting airbag. After the supporting airbag is filled with hot air, it will expand and deform. The expanded supporting airbag will squeeze the airbag limit frame. Under the squeezing action of the supporting airbag, the expansion plate will deform outward and the gap between the two expansion plates will become larger. At this time, the supporting airbag extends out from the gap between the two expansion plates and squeezes the cervical region. During the squeezing process of the cervical region, it will continuously bulge upward. Through this setting, the effect of changing the height of the cervical region can be achieved. The operator can change the amount of gas in the supporting airbag according to the patient's body type, thereby changing the height of the cervical region, enabling the height of the cervical region to adapt to patients with different body types, improving the comfort of the patient's cervical vertebra, and ensuring the stability of the patient's head.

[0018] During the operation, when the operator fills the second heating pipe with warm air, the warm air will enter the placement cavity. Since the inner skeleton is inserted into the placement cavity and the cross-sectional contour of the inner skeleton is a corrugated structure, the warm air in the placement cavity will flow in the placement cavity along the corrugated gaps of the inner skeleton, and then heat the patient on the medical head and neck pillow, ensuring that the body temperature of the patient's head and neck will not be too low; the warm air will also flow out from the air outlet holes and play a role in keeping the patient's body warm, ensuring that the patient's body temperature will not be too low during the operation, and improving the safety and success rate of the operation.

[0027] Furthermore, spatial relative terms such as "beneath", "below", "lower", "above", "upper", etc. are used herein for convenience in describing the relationship of one element or feature to another or other elements or features, as illustrated in the figures. The spatial relative terms are intended to cover different orientations in the use or operation of the device in addition to the orientation depicted in the figures.

[0028] As Figures 1 to 3As shown in the figure, an embodiment of the present invention provides a medical head and neck pillow device, including a rubber support pad 1. On one side of the top of the rubber support pad 1, an occipital region 101 is installed. At the middle position of the top of the rubber support pad 1, a cervical region 102 is installed. On the other side of the top of the rubber support pad 1, a shoulder and back region 103 is installed. The occipital region 101 has a downwardly concave arc-shaped contour, and a circular groove is provided at the middle position of the occipital region 101. The cervical region 102 has an upwardly convex arc-shaped contour, and the shoulder and back region 103 has a downwardly inclined slope; a limiting component, which is used to support and limit the head and neck of the patient. The limiting component is connected to the rubber support pad 1. The rubber support pad 1 provided in this application is made of rubber material, and the occipital region 101 on the rubber support pad 1 has a downwardly concave arc-shaped contour. Such a setting enables the occipital bone of the patient to be wrapped and limited by the arc-shaped contour of the occipital region 101 when the patient lies on the rubber support pad 1. In addition, since a circular groove is provided at the middle position of the occipital region 101, when the patient's head is placed on the occipital region 101, under the action of gravity, the patient's head will sink into the circular groove in the middle of the occipital region 101, thereby further wrapping and limiting the patient's head by means of the circular groove, improving the stability and comfort of the patient's head; the cervical region 102 at the middle position of the rubber support pad 1 has an upwardly convex arc-shaped contour. Such a setting is to enable the cervical position of the patient to be lifted upward by the cervical region 102 when the patient lies on the rubber support pad 1, so that the cervical region 102 can fill the gap between the head and the cervical vertebra when the patient lies flat, thereby improving the comfort of the patient's cervical position and ensuring that the patient will not shake due to poor comfort during the operation; the shoulder and back region 103 on the rubber support pad 1 has a downwardly inclined slope. The purpose of such a setting is to enable the shoulder and back region 103 to smoothly support the patient's shoulder and back when the patient lies on the surface of the rubber support pad 1, and then transition to a flat operating bed, thereby improving the comfort of the patient's shoulder and back.

[0029] Since the rubber support pad 1 is made of rubber material, and the rubber support pad 1, the occipital region 101, the cervical region 102 and the shoulder and back region 103 are of an integral structure, the rubber support pad 1 can be integrally injection molded during actual production, so that the processing technology of the head and neck pillow provided in this application is simpler and easier to be manufactured in actual production.

[0030] By setting the limit component, the height of the cervical region 102 can be adjusted, thereby adapting to the body types of different patients, improving the applicable range of this medical head and neck pillow. By adjusting the height of the cervical region 102, the adaptation effect between the patient's cervical vertebra and this medical head and neck pillow can also be improved, thereby enhancing the comfort of the patient and the support effect of the head and neck pillow on the patient, ensuring that the patient's head will not show unstable phenomena during the operation. In addition, the limit component can keep the patient warm, so that the patient will not have the phenomenon of too low body temperature during the long operation, improving the success rate of the operation and ensuring the safety of the patient.

[0031] As an implementation manner in this embodiment, as Figures 1 to 4 shown, the limit component includes an inner skeleton 2 inserted through the rubber support pad 1. A placement cavity 104 that matches the contour of the inner skeleton 2 is provided on the rubber support pad 1. The cross-sectional contour of the inner skeleton 2 is a corrugated structure. An occipital bone support frame 201 is fixedly connected to the inner skeleton 2 at the position corresponding to the occipital bone region 101 of the rubber support pad 1. The occipital bone support frame 201 is a segmented sheet structure, and the middle position of the occipital bone support frame 201 is hollowed out. The occipital bone support frame 201 corresponds to the position of the circular groove on the occipital bone region 101. The inner skeleton 2 is inserted into the placement cavity 104 on the rubber support pad 1. Since the contour of the placement cavity 104 matches the contour of the inner skeleton 2, the placement cavity 104 can limit the inner skeleton 2. The material of the inner skeleton 2 is hard plastic. Such a setting is to shape the overall contour of the rubber support pad 1 with the help of the inner skeleton 2, so as to ensure that the rubber support pad 1 will not deform during long-term use. Further, since the occipital bone support frame 201 is a segmented sheet structure and the middle position of the occipital bone support frame 201 is hollowed out, such a setting enables the occipital bone support frame 201 to support the patient's occipital bone, preventing the head from sinking too deeply into the circular groove when the patient lies in the circular groove in the middle of the occipital bone region 101, thereby causing discomfort to the patient. While ensuring that the occipital bone region 101 can wrap and limit the patient's occipital bone, it prevents the patient from feeling uncomfortable due to excessive depression of the head. In addition, installing the occipital bone support frame 201 at the position of the circular groove in the occipital bone region 101 can improve the structural strength of the rubber support pad 1 at this position and prevent the circular groove in the middle of the occipital bone region 101 from cracking during long-term use.

[0032] In this embodiment, as Figures 4 to 9As shown in the figure, an airbag limiting frame 202 is fixedly connected to the inner framework 2 at the position corresponding to the cervical vertebra area 102 of the rubber support pad 1. A blower base 3 is inserted into the bottom of the inner framework 2. An air duct mounting plate 303 is fixedly connected to one side of the blower base 3, and a shoulder and back support plate 305 is fixedly connected to the other side of the blower base 3. An air outlet hole 306 is formed in the shoulder and back support plate 305. A side sealing plate 206 is fixedly connected to one side of the inner framework 2. A bottom plate 207 is fixedly connected to the bottom of the side sealing plate 206. A splicing plate 208 with a "U" - shaped contour is fixedly connected to one side of the bottom plate 207. A positioning plate 301 adapted to the contour of the bottom plate 207 is fixedly connected to the top of the blower base 3. An insertion plate 304 corresponding to the position of the splicing plate 208 is installed on the top of the blower base 3. The insertion plate 304 is inserted into the "U" - shaped contour of the splicing plate 208. A first insertion cylinder 205 is fixedly connected to the bottom of the airbag limiting frame 202. A second insertion cylinder 302 corresponding to the position of the first insertion cylinder 205 is fixedly connected to the top of the blower base 3. An adaptation groove 209 is formed at the bottom of the first insertion cylinder 205. An adaptation block 310 whose contour coincides with the adaptation groove 209 is fixedly connected to the top of the second insertion cylinder 302. The blower base 3 is inserted into the bottom of the inner framework 2 from bottom to top. Specifically, since the splicing plate 208 on the bottom plate 207 has a "U" - shaped contour and the insertion plate 304 corresponds to the position of the splicing plate 208, when the user inserts the blower base 3 into the bottom plate 207 at the bottom of the inner framework 2 from bottom to top, the insertion plate 304 will be directly inserted into the "U" - shaped contour of the splicing plate 208, and the splicing plate 208 is used to limit the insertion plate 304. In addition, since the positioning plate 301 is adapted to the contour of the bottom plate 207, after the bottom plate 207 and the blower base 3 are inserted together, the positioning plate 301 and the bottom plate 207 will also be spliced together to limit each other, thereby improving the stability after the inner framework 2 and the blower base 3 are spliced. During the process of splicing the inner framework 2 and the blower base 3, the second insertion cylinder 302 will move towards the position of the first insertion cylinder 205. After the inner framework 2 and the blower base 3 are spliced together, the adaptation head on the second insertion cylinder 302 will also be inserted into the adaptation groove 209 in the first insertion cylinder 205. Since the contour of the adaptation head coincides with the adaptation groove 209, the two can limit each other. Since both the first insertion cylinder 205 and the second insertion cylinder 302 are made of plastic, they both have the ability to deform. The top of the adaptation head has a conical contour. During the process of inserting the adaptation head into the adaptation groove 209, the conical contour at the top of the adaptation head will be deformed by the adaptation groove 209. After the two are completely inserted together, the deformed adaptation head will automatically recover its deformation and be adapted to the contour of the adaptation groove 209, thereby realizing the splicing and fixing between the first insertion cylinder 205 and the second insertion cylinder 302. The splicing method of the above - mentioned structure is not only simple in structure but also good in stability after splicing. Such a setting improves the efficiency and convenience of the user in splicing the inner framework 2 and the blower base 3.

[0033] In this embodiment, as Figure 1 and Figures 8 to 10 shown, a first heating pipe 6 and a second heating pipe 7 are installed on the air duct mounting plate 303. The second heating supply is symmetrically installed on both sides of the first heating pipe 6. Expansion plates 203 are symmetrically installed on the top of the airbag limiting frame 202. The thickness of the expansion plate 203 is smaller than that of the airbag limiting frame 202, and there is a gap between the two expansion plates 203. A weakening groove 204 is formed on the expansion plate 203. A support airbag 5 that fits the size of the airbag limiting frame 202 is placed in the airbag limiting frame 202. An airbag inflation channel 307 communicating with the first heating pipe 6 is formed on the air blower base 3. One end of the airbag inflation channel 307 extends to the position of the second insertion cylinder 302. A communication cavity 308 and a heating channel 309 communicating with the second heating pipe 7 are formed on the air duct mounting plate 303. The communication cavity 308 communicates with the placement cavity 104, and the heating channel 309 extends into the shoulder and back support plate 305. When an operator fills the first heating pipe 6 with warm air, the warm air in the first heating pipe 6 will enter the second insertion cylinder 302 along the airbag inflation channel 307, and then enter the first insertion cylinder 205 through the second insertion cylinder 302. Finally, the warm air will enter the support airbag 5 along the first insertion cylinder 205. After the support airbag 5 is filled with hot air, it will expand and deform. The expanded support airbag 5 will squeeze the airbag limiting frame 202. Since the expansion plates 203 are symmetrically installed on the top of the airbag limiting frame 202 and there is a gap between the two expansion plates 203, under the squeezing action of the support airbag 5, the expansion plates 203 will deform outwards and the gap between the two expansion plates 203 will become larger. At this time, the support airbag 5 extends out from the gap between the two expansion plates 203 and squeezes the cervical vertebra area 102. During the squeezing process of the cervical vertebra area 102, it will continuously bulge upwards. Through such a setting, the effect of changing the height of the cervical vertebra area 102 can be achieved. The operator can change the amount of gas in the support airbag 5 according to the patient's body type, so as to change the height of the cervical vertebra area 102, make the height of the cervical vertebra area 102 adapt to patients of different body types, improve the comfort of the patient's cervical vertebra, and ensure the stability of the patient's head. In addition, since the thickness of the expansion plate 203 is smaller than that of the airbag limiting frame 202 and the weakening groove 204 is formed on the expansion plate 203, when the support airbag 5 squeezes the expansion plate 203, the weakened and thinned expansion plate 203 is more likely to deform and avoid the support airbag 5, so that the support airbag 5 can easily pass through the airbag limiting frame 202 to squeeze the cervical vertebra area 102.

[0034] Further, when the operator fills the second heating pipe 7 with warm air, the warm air will not only enter the placement cavity 104 along the communication cavity 308, but also enter the shoulder and back support plate 305 along the heating channel 309. The warm air entering the placement cavity 104 will spread along the contour of the placement cavity 104. Since the inner framework 2 is inserted into the placement cavity 104 and the cross-sectional contour of the inner framework 2 is a corrugated structure, the warm air in the placement cavity 104 will flow in the placement cavity 104 along the corrugated gaps of the inner framework 2. During the process of the warm air flowing in the placement cavity 104, it can heat the patient on the neck pillow, thus ensuring that the body temperature of the patient's head and neck will not be too low; the warm air entering the shoulder and back support plate 305 will flow out from the air outlet holes 306. Since the medical staff will cover the operating table and the patient during the operation, a relatively airtight environment will be created on the patient, so that the warm air flowing out from the air outlet holes 306 can play a role in keeping the patient warm. Through the setting of the above structure, the second heating pipe 7 can be used to heat the patient's head, neck and body, thus ensuring that the patient's body temperature will not be too low during the operation and improving the safety and success rate of the operation.

[0035] In this embodiment, as Figure 1 and Figure 6 shown, a fixed baffle 4 is installed on the side of the inner framework 2 away from the side sealing plate 206. The fixed baffle 4 and the inner framework 2 are fixedly connected by a regulating knob 404 in a threaded manner. A gas flow regulating disc 401 is rotatably connected to the fixed baffle 4. The gas flow regulating disc 401 and the fixed baffle 4 are both provided with a first adjusting hole 402 and a second adjusting hole 403. When the operator inserts the inner framework 2 into the rubber support pad 1, the side sealing plate 206 on one side of the inner framework 2 will abut against one side of the rubber support pad 1 and seal one side of the placement cavity 104. At this time, the operator can fix the fixed baffle 4 to the other side of the inner framework 2. Since a threaded hole adapted to the size of the regulating knob 404 is provided on the inner framework 2, the operator can install and fix the fixed baffle 4 to the inner framework 2 by means of the regulating knob 404. After the fixed baffle 4 is installed, the other side of the placement groove can be sealed. Therefore, the warm air flowing out from the second heating pipe 7 will flow in the sealed placement groove.

[0036] Further, since the gas flow regulating disc 401 and the fixed baffle 4 are both provided with a first adjusting hole 402 and a second adjusting hole 403, the operator can change the relative positions between the first adjusting hole 402 and the second adjusting hole 403 on the gas flow regulating disc 401 and the fixed baffle 4 by rotating the gas flow regulating disc 401, so as to change the quantity of warm air flowing out from the gas flow regulating disc 401, and thus indirectly change the temperature in the placement groove to prevent the patient from being scalded due to too high temperature.

[0037] The working principle of the technical solution provided by the present invention is as follows: When in use, let the patient lie flat on the rubber support pad 1, place the occipital bone of the patient in the occipital region 101, and place the cervical vertebrae of the patient in the cervical region 102. Due to the downwardly concave arc-shaped contour of the occipital region 101, when the patient lies on the rubber support pad 1, the occipital bone of the patient can be wrapped and limited by the arc-shaped contour of the occipital region 101. Since the cervical region 102 has an upwardly convex arc-shaped contour, when the patient lies on the rubber support pad 1, the position of the cervical vertebrae of the patient can be lifted upward by the cervical region 102, so that the cervical region 102 can fill the gap between the head and the cervical vertebrae when the patient lies flat, improving the comfort of the cervical vertebrae position of the patient and ensuring that the patient will not shake due to poor comfort during the operation; since the shoulder and back region 103 has a downwardly inclined slope, when the patient lies on the surface of the rubber support pad 1, the shoulder and back region 103 can smoothly support the shoulder and back of the patient and then transition to the flat operating table, thereby improving the comfort of the shoulder and back of the patient. When the operator fills the first heating pipe 6 with warm air, the warm air in the first heating pipe 6 will enter the second insertion cylinder 302 along the airbag inflation channel 307, then enter the first insertion cylinder 205 through the second insertion cylinder 302, and finally the warm air will enter the support airbag 5 along the first insertion cylinder 205. After the support airbag 5 is filled with hot air, it will expand and deform. The expanded support airbag 5 will squeeze the airbag limit frame 202. Under the squeezing action of the support airbag 5, the expansion plate 203 will deform outward and the gap between the two expansion plates 203 will become larger. At this time, the support airbag 5 extends out from the gap between the two expansion plates 203 and squeezes the cervical region 102. During the squeezing process of the cervical region 102, it will continuously bulge upward. Through such a setting, the effect of changing the height of the cervical region 102 can be achieved. The operator can change the amount of gas in the support airbag 5 according to the body type of the patient, so as to change the height of the cervical region 102, so that the height of the cervical region 102 can be adapted to patients of different body types, improving the comfort of the cervical vertebrae of the patient and ensuring the stability of the patient's head; when the operator fills the second heating pipe 7 with warm air, the warm air will not only enter the placement cavity 104 along the communication cavity 308, but also enter the shoulder and back support plate 305 along the heating channel 309. The warm air entering the placement cavity 104 will spread along the contour of the placement cavity 104. Since the inner skeleton 2 is inserted in the placement cavity 104 and the cross-sectional contour of the inner skeleton 2 is a corrugated structure, the warm air in the placement cavity 104 will flow in the placement cavity 104 along the corrugated gaps of the inner skeleton 2. During the process of the warm air flowing in the placement cavity 104, it can heat the patient on the head and neck pillow, thereby ensuring that the body temperature of the patient's head and neck will not be too low; the warm air entering the shoulder and back support plate 305 will flow out from the air outlet holes 306 and play a role in keeping the patient warm, thereby ensuring that the body temperature of the patient will not be too low during the operation and improving the safety and success rate of the operation.
