Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a cervical spine injury pressure ulcer fixation pillow. Background Technology

[0002] Cervical spine injury pressure ulcer fixation pillows are medical assistive devices specifically designed for patients with cervical spine injuries. Their purpose is to provide stable fixation of the cervical spine and prevent pressure ulcers. They are typically ergonomically designed to fit the patient's head size, neck thickness, and length, ensuring the cervical spine maintains a functional position when lying flat or turning over. Currently, air mattresses are used as the basic support device for preventing cervical spine injuries. By dynamically distributing body pressure, they reduce contact pressure on bony prominences such as the sacrum and coccyx. Combined with axial turning every two hours, this can shorten the duration of pressure on local tissues. For patients requiring head and neck immobilization, millet pillows are used clinically instead of traditional towel pads. Their granular filling can adaptively shape according to the patient's head shape, improving the evenness of pressure distribution at the back of the head. Combined with cylindrical neck pillows, they can maintain the physiological curvature of the cervical spine. However, their deformation and the massage effect on the patient's head depend on head movement, and the massage mode is relatively simple. Therefore, there is a lack of innovative solutions in clinical practice that provide diversified stimulation and active massage to the patient's head.

[0003] A search revealed that while some existing patents have improved head massage for patients, they still fail to overcome the core issues of providing diversified stimulation and active head massage. For example, Chinese patent (CN217310923U) discloses an air cushion pillow for cervical spine injury patients to prevent pressure sores on the head. This pillow connects the head unit to an external air pump, allowing for cyclical inflation to prevent pressure sores. While this solution provides active head massage, it only offers a single pneumatic massage function and does not provide diversified stimulation. Another example is a multifunctional cervical spine fixation pillow (CN211187699U), which uses a separate head massager for mechanical head massage. Although this solution provides active head massage, its integration with other structures is weak, and it still cannot provide diversified stimulation.

[0004] In summary, the main drawback of the above-mentioned solution is that it only achieves active massage of the patient's head, failing to overcome the limitation of "providing diversified stimulation to the patient's head while actively massaging it," resulting in limited massage effect on the patient's head during use. Therefore, the applicant has invented a cervical spine injury anti-pressure ulcer fixation pillow capable of actively massaging the patient's head while simultaneously providing pneumatic and mechanical massage. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a cervical spine injury pressure ulcer prevention and fixation pillow, which uses a mechanical massage component and a pneumatic massage component to work together to simultaneously perform mechanical and pneumatic massage on the patient's head, providing the patient with diverse stimulation, thereby promoting blood circulation and reducing the possibility of pressure ulcers on the patient's head.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A cervical spine injury pressure ulcer fixation pillow includes a controller and a hollow fixation pillow body. A protective shell is detachably connected inside the fixation pillow body. A partition is fixedly connected to the inner side wall of the protective shell, and the partition divides the inside of the protective shell into a fixation cavity and a drive cavity from top to bottom. A telescopic component is fixedly connected to the inner side wall of the drive cavity. The controller is used to control the extension and retraction of the output shaft of the telescopic component. A pneumatic massage component for performing pneumatic massage on the patient's head is provided inside the fixation cavity.

[0007] A circulation box is fixedly connected to the bottom wall of the drive cavity. A circulation plate is slidably fitted to the inner side wall of the circulation box. A double-sided rack is fixedly connected to one side of the circulation plate. The end of the double-sided rack away from the circulation plate extends through the side wall of the circulation box to the outside of the circulation box and is fixedly connected to the output shaft of the telescopic component. A mechanical massage component for mechanically massaging the patient's head is provided on the double-sided rack.

[0008] The circulation box is equipped with an air supply component for driving the pneumatic massage component through gas circulation.

[0009] The technical principles of the above solution are as follows: Staff guide the patient's head onto the fixed pillow. A controller then moves the telescopic output shaft back and forth, causing it to sequentially drive the double-sided rack and circulation plate in a reciprocating motion. This pumps air from the circulation chamber to the pneumatic massage component, providing a pneumatic massage to the patient's head while simultaneously securing it in place. After the air delivery is complete, the air delivery component draws the air back into the circulation chamber, completing the air circulation process.

[0010] During this process, the double-sided rack also drives the mechanical massage component to perform a mechanical massage on the patient's head. When the massage frequency needs to be adjusted, the operator can control the extension and retraction speed of the telescopic output shaft through the controller, thereby adjusting the massage frequency of both the pneumatic and mechanical massage components.

[0011] The above approach has the following beneficial effects: 1. This invention utilizes a combination of mechanical and pneumatic massage components to simultaneously provide mechanical and pneumatic massage to the patient's head, offering diverse stimulation and thus promoting blood circulation while reducing the likelihood of pressure sores on the patient's head.

[0012] 2. By adjusting the extension and retraction frequency of the output shaft of the telescopic component, this invention can precisely control the massage frequency of the mechanical massage component and the pneumatic massage component on the patient, thereby adapting to patients with different degrees of cervical spine injury and reducing the possibility of secondary injury to the patient while massaging the patient.

[0013] 3. During operation, the pneumatic component of this invention also provides pneumatic support for the patient's head and neck to disperse local pressure and reduce the possibility of pressure sores caused by prolonged pressure. Simultaneously, because the pneumatic component provides pneumatic support for the patient's head and neck, it also maintains the normal physiological curvature of the cervical spine during support, thereby reducing patient discomfort.

[0014] Furthermore, the air supply assembly includes an air inlet pipe and an air outlet pipe symmetrically connected to the circulation box. Several connecting cylinders are fixedly connected to the bottom wall of the drive chamber. The end of each connecting cylinder away from the bottom wall of the drive chamber is fixedly connected to the bottom of the partition plate, and each connecting cylinder is connected to the inside of the fixed chamber.

[0015] The inlet and outlet pipes are connected to the circulation box with an inlet check valve and an outlet check valve, respectively. The ends of the inlet and outlet pipes away from the circulation box are connected to the adjacent connecting cylinder. The circulation box is connected with an inflation check valve. The fixed pillow body and the protective shell are both opened with inflation holes, and the inflation holes are all located on the same straight line as the inflation check valve.

[0016] Beneficial effects: The design of the connecting cylinder being fixedly connected to the bottom of the partition and the bottom wall of the drive cavity at both ends respectively enables it to provide support for the partition, reducing the possibility of the partition sinking due to external forces and improving the stability of the fixed pillow.

[0017] Furthermore, the air supply assembly includes T-shaped pipes that are symmetrically fixedly connected and communicate with the circulation box. Several connecting cylinders are fixedly connected to the bottom wall of the drive cavity. The end of each connecting cylinder away from the bottom wall of the drive cavity is fixedly connected to the bottom of the partition plate, and each connecting cylinder communicates with the inside of the fixed cavity.

[0018] The T-shaped tubes are symmetrically connected with inlet and outlet one-way valves. Both ends of the T-shaped tubes are connected to the adjacent connecting cylinders through the inlet and outlet one-way valves. The bottom of the circulation box is connected with an inflation one-way valve. The fixed pillow body and the protective shell are both opened with inflation holes, and the inflation holes are all located on the same straight line as the inflation one-way valve.

[0019] Beneficial effects: The symmetrically designed T-shaped tubes and connecting cylinders form a stable support structure inside the fixation pillow. They not only facilitate gas transmission but also strengthen the overall structure of the fixation pillow, reducing the possibility of deformation under stress and thus ensuring stable support for the patient's head.

[0020] Furthermore, the air supply assembly includes an air inlet pipe and an air outlet pipe symmetrically connected to the circulation box. The air inlet pipe and the air outlet pipe are respectively connected to an air inlet check valve and an air outlet check valve at the connection points with the circulation box, and the ends of the air inlet pipe and the air outlet pipe away from the circulation box are connected to the inside of the fixed cavity. An inflation check valve is connected to the circulation box, and inflation holes are opened on the fixed pillow body and the protective shell. The inflation holes are all located on the same straight line as the inflation check valve.

[0021] Beneficial effects: By directly connecting the two ends of the inlet and outlet pipes to the inside of the circulation box and the fixed cavity, the gas flow path is simplified, thereby improving the gas delivery efficiency.

[0022] Furthermore, the pneumatic massage assembly includes a first airbag and a second airbag symmetrically fixedly connected to the top of the partition along the length of the partition. The connecting cylinders connected to the air inlet pipe are all connected to the first airbag, and the connecting cylinders connected to the air outlet pipe are all connected to the second airbag. Several third airbags are also fixedly connected to the top of the partition. The first airbag and the second airbag are all connected to their adjacent third airbags, and the adjacent third airbags are interconnected with each other.

[0023] Beneficial effects: When airflow enters the first airbag through the inlet pipe and connecting tube, the first airbag can receive the airflow first and inflate, generating direct massage pressure on the corresponding part of the patient. At the same time, the gas in the first airbag will also enter the third airbag connected to it and inflate. At this time, the airflow can be evenly diffused in each of the third airbags, producing a multi-layered, wave-like pneumatic massage experience, simulating the complex movements and rhythms that are closer to human hand massage, enhancing the comfort and effect of the massage. Finally, the airflow will also enter the second airbag through the third airbag connected to it, and re-enter the circulation box through the adjacent connecting tube and air outlet pipe to achieve gas circulation.

[0024] Furthermore, the circulation chamber is equipped with a heating component for heating the gas inside. The heating component includes a temperature sensor fixedly connected to the inner wall of the circulation chamber, a heating plate fixedly connected to the bottom wall of the circulation chamber, and a controller for receiving the temperature signal monitored by the temperature sensor in real time and controlling the opening and closing of the heating plate based on the temperature signal.

[0025] Beneficial effects: The heating plate in the heating component can heat the gas in the circulation box. When the airflow entering the pneumatic massage component acts on the patient's head and neck, it can dilate the muscles and blood vessels in the patient's neck and head, thereby increasing the efficiency of blood circulation and allowing the patient's muscles to relax more fully, thus improving the overall comfort of the pneumatic massage.

[0026] Furthermore, the mechanical massage component includes several gears that rotate symmetrically on the bottom wall of the drive cavity. Each gear meshes with a double-sided rack. Each gear has an extension rod fixedly connected to its top. The extension rods pass through the partition and the top wall of the protective shell and extend to the outside of the protective shell where a massage block is fixedly connected.

[0027] Beneficial effects: The gear and double-sided rack design allows the gears to rotate synchronously under the drive of the rack, which in turn drives the massage block at the top of the extension rod. Because the gears are symmetrically arranged, the massage block can cover the patient's head and neck, thus achieving a comprehensive massage of the head and neck.

[0028] Furthermore, the top of the partition is provided with a limiting component for limiting the first airbag, the second airbag and the third airbag. The limiting component includes a support frame fixedly connected to the top of the partition. The support frame has a grid structure, and the first airbag, the second airbag and the third airbag are all located in the grid adjacent to it.

[0029] Beneficial effects: During pneumatic massage, the first, second, and third airbags continuously inflate and deflate, resulting in periodic expansion and contraction. During this process, they may shift under the influence of force. However, because the support frame uses a grid structure, it can fix the first, second, and third airbags in their respective grids, thereby limiting the range of movement of the airbags and ensuring that the airbags are always inflated and deflated in the preset positions, thus ensuring the accuracy and stability of the massage.

[0030] Furthermore, all the massage blocks are hemispherical.

[0031] Beneficial effects: The hemispherical massage block can adapt to the surface curve of the patient's head and neck, allowing it to make close contact with the patient's skin. This reduces the possibility of excessive local pressure or inadequate massage, thus enabling the patient to experience a more comfortable massage and improving patient comfort.

[0032] Furthermore, a pressure sensor is fixedly connected to the inner wall of the circulation chamber, and the controller is electrically connected to a worker terminal. The controller is used to receive the pressure signal inside the circulation chamber monitored by the pressure sensor in real time and send the pressure signal to the worker terminal.

[0033] Beneficial effects: The controller sends air pressure signals to the staff terminal in real time, allowing staff to intuitively understand the air pressure changes in the circulation box. This enables staff to judge the operation of the fixed pillow based on the air pressure changes, so that if the fixed pillow fails to operate or other abnormalities occur, staff can go and deal with them in a timely manner.

[0034] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The following detailed description illustrates the specific implementation method: Example 1: As shown in the attached document Figure 1 and Figure 3 The image shows a cervical spine injury pressure ulcer prevention pillow, comprising a controller and a hollow pillow body. A protective shell 1 is detachably installed inside the pillow body. A partition 2 is integrally formed on the inner wall of the protective shell 1, dividing the interior of the protective shell 1 into a fixing cavity and a driving cavity from top to bottom. A telescopic component is screwed to the inner wall of the driving cavity. The controller controls the extension and retraction of the output shaft of the telescopic component. A pneumatic massage assembly for pneumatically massaging the patient's head is provided inside the fixing cavity. In this embodiment, an electric telescopic rod 3 is used as the telescopic component.

[0041] The bottom wall of the drive cavity is integrally formed with a circulation box 4. The inner side wall of the circulation box 4 is laterally slidably fitted with a circulation plate 5. A double-sided rack 6 is integrally formed on one side of the circulation plate 5. The end of the double-sided rack 6 away from the circulation plate 5 passes through the side wall of the circulation box 4 and extends to the outside of the circulation box 4, where it is fixedly connected to the output shaft of the electric telescopic rod 3 with a screw.

[0042] like Figure 3As shown, the circulation box 4 is equipped with an air supply assembly, which includes an air inlet pipe 7 and an air outlet pipe 8 symmetrically connected to the circulation box 4. Several connecting cylinders 9 are integrally formed on the bottom wall of the drive cavity. The end of each connecting cylinder 9 away from the bottom wall of the drive cavity is integrally formed with the bottom of the partition plate 2, and each connecting cylinder 9 is connected to the inside of the fixed cavity.

[0043] like Figure 4 As shown, the inlet pipe 7 and outlet pipe 8 are connected to the circulation box 4 by an inlet check valve 10 and an outlet check valve 11, respectively. The ends of the inlet pipe 7 and outlet pipe 8 away from the circulation box 4 are connected to the adjacent connecting cylinder 9. An inflation check valve 12 is connected to the circulation box 4. Inflation holes are opened on the fixed pillow body and the protective shell 1. The inflation holes are all located on the same straight line as the inflation check valve 12.

[0044] A pressure sensor 13 is fixedly connected to the inner wall of the circulation box 4 by screws. The controller is electrically connected to the operator terminal. The controller is used to receive the pressure signal inside the circulation box 4 monitored by the pressure sensor 13 in real time and send the pressure signal to the operator terminal.

[0045] In this embodiment, the flow direction of the intake check valve 10 is one-way from the circulation box 4 to the inside of the intake pipe 7, the flow direction of the exhaust check valve 11 is one-way from the exhaust pipe 8 to the inside of the circulation box 4, and the flow direction of the inflation check valve 12 is one-way from the outside to the inside of the circulation box 4.

[0046] Specifically, the staff first guides the patient to lie flat, placing their head and neck on the fixed pillow body. Then, air is injected into the circulation box 4 through the inflation hole and the inflation one-way valve 12. During this process, since the two ends of the air inlet pipe 7 are connected to the circulation box 4 and the connecting cylinder 9 respectively, the air inlet one-way valve 10 is located at the connection between the air inlet pipe 7 and the circulation box 4, and the connecting cylinder 9 is connected to the inside of the fixed cavity, the gas can enter the fixed cavity through the air inlet pipe 7 and the connecting cylinder 9 in sequence to inflate the pneumatic massage component.

[0047] Meanwhile, since both ends of the air outlet pipe 8 are connected to the circulation box 4 and the connecting cylinder 9 respectively, and the one-way valve 11 is located at the connection between the air outlet pipe 8 and the circulation box 4, after the pneumatic massage component is fully inflated, gas can still enter the circulation box 4 from the connecting cylinder 9 and the air outlet pipe 8. At this time, since the connecting cylinder 9 is located between the bottom wall of the drive cavity and the bottom of the partition 2, it can also support the partition 2, reducing the possibility of deformation of the partition 2.

[0048] After inflation is completed, the staff, based on the patient's cervical spine injury, sets the extension / retraction rate of the output shaft of the electric telescopic rod 3 via the controller, causing it to reciprocate. At this time, the output shaft of the electric telescopic rod 3 drives the double-sided rack 6, which is fixed to it with screws, to reciprocate laterally. The double-sided rack 6 then drives the integrated circulation plate 5 to reciprocate laterally, thus agitating the gas inside the circulation box 4. Figure 4 As shown, when the output shaft of the electric telescopic rod 3 extends, it sequentially drives the double-sided rack 6 and the circulation plate 5 to move to the right. At this time, the circulation plate 5 pushes the gas in the circulation box 4 out, so that it enters the pneumatic massage assembly through the air inlet pipe 7 and the connecting cylinder 9. When the output shaft of the electric telescopic rod 3 retracts, it sequentially drives the double-sided rack 6 and the circulation plate 5 to move to the left. At this time, the circulation plate 5 slides in the circulation box 4, drawing the gas in the pneumatic massage assembly back into the circulation box 4, so as to perform pneumatic massage operation on the patient through the flow of gas.

[0049] During this process, the air pressure sensor 13 monitors the air pressure signal inside the circulation box 4 in real time, sends the air pressure signal to the controller, and the controller then sends it to the staff terminal. In this embodiment, the staff sets the air pressure threshold range through the controller. When the air pressure signal is within the air pressure threshold range, it indicates that the fixed pillow body is operating normally; when the air pressure signal is outside the air pressure threshold range, it indicates that the fixed pillow body has malfunctioned. At this time, the staff will go to the patient to replace or repair the fixed pillow body.

[0050] like Figure 2 As shown, the pneumatic massage assembly includes a first airbag 14 and a second airbag 15 (each with a volume of 200ml) symmetrically fixed and adhered to the top of the partition 2 along its length. Connecting cylinders 9, which communicate with the air inlet pipe 7, are all connected to the first airbag 14, and connecting cylinders 9, which communicate with the air outlet pipe 8, are all connected to the second airbag 15. Several third airbags 16 (each with a volume of 300ml) are also fixedly adhered to the top of the partition 2. The first airbag 14 and the second airbag 15 are all connected to their adjacent third airbags 16, and the adjacent third airbags 16 are interconnected. Figure 7 As shown.

[0051] Specifically, since the connecting tubes 9 connected to the air inlet pipe 7 are all connected to the first airbag 14, gas can enter the first airbag 14 through the air inlet pipe 7 and the connecting tubes 9, causing it to inflate. Furthermore, since the first airbag 14 is connected to each of its adjacent third airbags 16, and the adjacent third airbags 16 are interconnected, gas inside the first airbag 14 can also enter the adjacent third airbags 16 and diffuse evenly within each third airbag 16, providing stable support for the patient's head and neck.

[0052] Meanwhile, since each of the second airbags 15 is connected to its adjacent third airbag 16, and each of the second airbags 15 is connected to the connecting tube 9 which is connected to the air outlet tube 8, the gas in the third airbag 16 adjacent to the second airbag 15 will enter the second airbag 15 and return to the circulation box 4 in sequence through the connecting tube 9 and the air outlet tube 8. During this process, the first airbag 14, the third airbag 16, and the second airbag 15 expand sequentially, forming a wave-like pneumatic massage, thereby reducing the possibility of pressure sores on the patient's head and neck.

[0053] like Figure 4 As shown, the circulation chamber 4 is equipped with a heating component for heating the gas inside it. The heating component includes a temperature sensor 17 (with a measurement accuracy of ±0.5-±2℃) that is fixedly connected to the inner wall of the circulation chamber 4 with screws. A heating plate 18 is embedded in the bottom wall of the circulation chamber 4. The controller is used to receive the temperature signal monitored by the temperature sensor 17 in real time and control the opening and closing of the heating plate 18 based on the temperature signal.

[0054] Specifically, staff set a heating threshold (35-42℃) through the controller, and the temperature sensor 17 monitors the temperature signal inside the circulation chamber 4 in real time. When the temperature signal is lower than the heating threshold, the controller controls the heating plate 18 to start, which heats the gas inside the circulation chamber 4. This allows the gas acting on the patient's skin surface to promote the dilation of blood vessels in the patient's head and neck muscles, thereby improving the efficiency of blood circulation and further reducing the possibility of pressure sores on the patient's head and neck.

[0055] like Figure 3 As shown, the double-sided rack 6 is equipped with a mechanical massage component for mechanically massaging the patient's head.

[0056] The mechanical massage assembly includes several gears 19 that are symmetrically rotated and fitted on the bottom wall of the drive cavity. All gears 19 mesh with double-sided racks 6. Each gear 19 has an extension rod 20 fixedly attached to its top. The extension rod 20 extends through the partition 2 and the top wall of the protective shell 1 and extends to the outside of the protective shell 1, where a hemispherical massage block 21 is fixedly bonded.

[0057] Specifically, when the double-sided rack 6 moves laterally, it will also drive the gear 19 meshing with it to rotate, causing the gear 19 to drive the extension rod 20 fixedly connected to it to rotate, and then the extension rod 20 will drive the massage block 21 attached to it to rotate, so that it works in conjunction with the pneumatic massage to perform mechanical massage on the patient's head and neck.

[0058] like Figure 2As shown, the top of the partition 2 is provided with a limiting component for limiting the first airbag 14, the second airbag 15 and the third airbag 16. The limiting component includes a support frame 22 integrally formed on the top of the partition 2. The support frame 22 has a grid structure. The first airbag 14, the second airbag 15 and the third airbag 16 are all located in the grid adjacent to it (the grid side length is 30-60mm).

[0059] Specifically, the first airbag 14, the second airbag 15, and the third airbag 16 will repeatedly expand and contract during the operation of the fixed pillow body. They may shift during this process. By placing them in the support frame 22, their range of movement can be limited, so that the first airbag 14, the second airbag 15, and the third airbag 16 can be in their predetermined expansion position and make contact with the patient's head and neck each time they expand.

[0060] This invention utilizes a combination of mechanical and pneumatic massage components to simultaneously provide mechanical and pneumatic massage to the patient's head, offering diverse stimulation and promoting blood circulation while reducing the likelihood of pressure sores. Furthermore, the invention employs a heating component to heat the gas applied to the patient's skin, causing vasodilation in the head and neck, further promoting blood circulation and minimizing the risk of pressure sores.

[0061] Example 2: The difference from Example 1 is that, since the air delivery component is used to drive the pneumatic massage component through gas circulation, in addition to the air delivery component of Example 1, the air delivery component can also be as follows: Figure 5 As shown, it includes a symmetrically integrally formed T-shaped tube 23 connected to the circulation box 4. Several connecting cylinders 9 are integrally formed on the bottom wall of the drive cavity. The end of the connecting cylinder 9 away from the bottom wall of the drive cavity is integrally formed with the bottom of the partition plate 2, and the connecting cylinder 9 is connected to the inside of the fixed cavity.

[0062] The T-shaped tube 23 is symmetrically connected with an inlet one-way valve 10 and an outlet one-way valve 11. Both ends of the T-shaped tube 23 are connected to the adjacent connecting cylinder 9 through the inlet one-way valve 10 and the outlet one-way valve 11. The bottom of the circulation box 4 is connected with an inflation one-way valve 12. The fixed pillow body and the protective shell 1 are both opened with inflation holes. The inflation holes are all located on the same straight line as the inflation one-way valve 12. The rest of the structure is the same as in embodiment 1.

[0063] Specifically, in this embodiment, when the circulation plate 5 moves towards... Figure 4 When the gas moves to the right in the circulation box 4, it can sequentially enter the connecting cylinder 9 through the T-shaped pipe 23 and the inlet check valve 10, causing it to sequentially inflate the first airbag 14, the third airbag 16, and the second airbag 15 in the fixed cavity; when the circulation plate 5 in the circulation box 4 moves to the right... Figure 4When the gas moves to the left, the gas in the second airbag 15, the third airbag 16 and the first airbag 14 are sequentially drawn back into the circulation box 4 to realize the gas circulation operation, so that the effect of the gas delivery component in this embodiment is the same as the effect of the gas delivery component in embodiment 1.

[0064] As long as the gas circulation effect can be achieved, any gas delivery component used is within the scope of protection sought by the claims of this application.

[0065] Example 3: In addition to the air supply components of Embodiments 1 and 2, the structure of the air supply component can also be as follows: Figure 6 As shown, it includes an air inlet pipe 7 and an air outlet pipe 8 symmetrically connected to the circulation box 4. Each connection point between the air inlet pipe 7 and the air outlet pipe 8 and the circulation box 4 is connected to an air inlet check valve 10 and an air outlet check valve 11, respectively. The ends of the air inlet pipe 7 and the air outlet pipe 8 furthest from the circulation box 4 are connected to the interior of the fixed cavity. An inflation check valve 12 is connected to the circulation box 4. Inflation holes are provided on both the fixed pillow body and the protective shell 1, and these inflation holes are aligned with the inflation check valve 12. In this embodiment, the end of the air inlet pipe 7 furthest from the circulation box 4 is connected to the first airbag 14, and the end of the air outlet pipe 8 furthest from the circulation box 4 is connected to the second airbag 15. The remaining structure is the same as in Embodiment 1.

[0066] Specifically, when the gas in the circulation box 4 is discharged, it can directly enter the first airbag 14 through the air inlet pipe 7, and be inflated in the order of the first airbag 14, the third airbag 16, and the second airbag 15. At the same time, when the circulation plate 5 moves in the circulation box 4 and generates negative pressure, it can sequentially draw the gas that originally existed in the second airbag 15, the third airbag 16, and the first airbag 14 into the circulation box 4, realizing the gas circulation operation, so that the effect achieved by the gas delivery component in this embodiment is the same as the effect of the gas delivery component in embodiment 1.

[0067] As long as the effect of sequentially inflating the first airbag 14, the third airbag 16, and the second airbag 15, and sequentially expelling the gas from the second airbag 15, the third airbag 16, and the first airbag 14 during deflating is achieved, regardless of the type of air delivery component used, it is within the scope of protection of the claims in this application.

[0068] Scope of Protection: The core inventive point of this invention lies in "actively performing simultaneous pneumatic and mechanical massage on the patient's head, providing diverse stimulation to the patient's head," and its scope of protection includes: 1. Transmission mechanism: Any mechanism that drives the moving parts (such as the circulation plate in Example 1) to move through telescopic components (electric telescopic rods, pneumatic telescopic rods, hydraulic rods, etc.) and simultaneously drives the massage mechanism to operate through gear and rack meshing and other transmission methods to achieve the mechanical massage effect is considered an equivalent replacement.

[0069] 2. Gas delivery mechanism: Any structure that achieves gas delivery through pipes or other means is considered an equivalent replacement.

[0070] 3. Massage Mechanisms: Any structure that adjusts the inflation sequence of airbags to inflate them along a specific path is considered an equivalent replacement. Any structure that combines pneumatic and mechanical massage is considered an equivalent replacement.

[0071] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
