Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a head and shoulder pillow for use during surgery. Background Technology

[0002] During surgery, a patient's body temperature decreases as the operation progresses. Intraoperative hypothermia can increase the infection rate of the wound, affect coagulation function, impair metabolism, increase cardiovascular complications, and delay postoperative recovery. Furthermore, prolonged pressure on local tissues can lead to persistent hypoxia, eventually resulting in ulceration and necrosis, causing pressure sores (pressure ulcers, bedsores). Current operating room techniques typically use a hard bed board to support the patient and cover them with warm blankets for insulation. However, the patient's head and neck areas are the first to come into contact with the hard bed board and bear significant pressure under their weight, increasing the risk of pressure sores in these areas. Additionally, these areas are exposed to varying degrees, and as important heat dissipation organs, they are prone to abnormal body temperature, indicating room for improvement.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The following is for reference. Figures 1-5 A head and shoulder pillow 100 used during surgery according to an embodiment of the present invention is described.

[0031] like Figures 1-5 As shown, the surgical head and shoulder pillow 100 according to an embodiment of the present invention includes: a pillow pad 10 and a control component 20. The pillow pad 10 may define an inner cavity (not shown in the figure), and the inner cavity may be provided with a water pipe 30. The control component 20 may include a first pump body (not shown in the figure) and a second pump body (not shown in the figure). The first pump body is connected to the water pipe 30. The first pump body can drive a heat exchange medium (such as water) to circulate along the water pipe 30, so that the heat exchange medium can circulate through the pillow pad 10 and absorb or release heat through the pillow pad 10 to exchange heat with the patient's head and neck, which is beneficial to keep the patient's head and neck warm.

[0032] The water pipe 30 can extend circumferentially along the pillow pad 10, which can increase the flow range of the heat exchange medium within the pillow pad 10, improve the heat exchange effect of the heat exchange medium, improve the heat preservation effect on the patient's head and neck, and prevent the patient from having abnormal body temperature due to prolonged surgery. The second pump body can be connected to the inner cavity and can dynamically inflate and deflate the pillow pad 10. That is, the second pump body can inflate the pillow pad 10, so that the patient's head and neck are in contact with the pillow pad 10, and the pillow pad 10 can deform to distribute pressure when it is in contact with the head and neck.

[0033] The second pump can circulate air release and inflation when the pillow 10 is inflated to a level sufficient to support the patient's head, neck, and shoulders. This maintains the air volume within the pillow 10 within a certain range and promotes its deformation to further distribute pressure. This ensures normal blood flow in the tissues of the patient's head, neck, and shoulders, preventing pressure sores from developing due to prolonged surgery. It reduces the risk of pressure sores in the patient's head, neck, and shoulders, thereby improving surgical outcomes and facilitating postoperative recovery.

[0034] The head and shoulder pillow 100 used during surgery according to an embodiment of the present invention, by setting a pillow pad 10 and by setting a control component 20, allows the heat exchange medium to circulate through the pillow pad 10 to keep the patient's head and neck warm, preventing abnormal body temperature due to prolonged surgery. At the same time, it can realize dynamic inflation and deflation of the pillow pad 10, which can promote the deformation of the pillow pad 10 to distribute pressure, ensure normal blood flow in the tissues of the patient's head and neck, and prevent pressure sores from forming in the patient's head and neck due to prolonged surgery, thereby improving the surgical effect and facilitating the patient's postoperative recovery.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the pillow 10 may include: a head pillow 11 and a plurality of protective pads 12. The patient's head can contact the upper surface of the head pillow 11, which can distribute the pressure on the patient's head, ensure normal blood flow in the tissues of the patient's head, prevent pressure sores from forming on the patient's head due to prolonged surgery, and reduce the risk of pressure sores forming on the patient's head.

[0036] Multiple protective pads 12 can be disposed on the outer periphery of the headrest pad 11, and the multiple protective pads 12 are arranged along the circumference of the headrest pad 11, so that the multiple protective pads 12 can be located on the outer periphery of the patient's head, which is conducive to protecting the patient's head. The headrest pad 11 can define a first cavity, and each protective pad 12 can define a second cavity. The second cavity is connected to the first cavity, so that the heat exchange medium can flow through the headrest pad 11 and the protective pads 12 along the vent pipe 24. This can increase the range of flow of the heat exchange medium in the headrest pad 10, improve the heat exchange effect of the heat exchange medium, improve the heat preservation effect on the patient's head and neck, and prevent the patient from having abnormal body temperature due to prolonged surgery.

[0037] Among the multiple protective pads 12, two adjacent protective pads 12 can be connected together to cooperate with the headrest pad 11 to define the headrest cavity. This can limit the position of the patient's headrest, improve the safety of the operation, and facilitate the contact between the multiple protective pads 12 and the outer periphery of the patient's headrest, thereby improving the protection of the patient's headrest and reducing the exposed area of ​​the patient's headrest. This can also improve the heat preservation effect of the patient's headrest and prevent the patient from developing abnormal body temperature due to prolonged operation.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the lower outer surface of the headrest 11 may have a support portion 113 for supporting the headrest 11. At least a portion of the support portion 113 may protrude away from the headrest 11 to form a limiting space in the inner cavity. The headrest 11 may also include a buffer 40, which may be disposed within the limiting space. The buffer 40 may contact the upper inner surface of the headrest 11 and undergo elastic deformation when the patient's head presses against the headrest 11, thereby improving the support effect on the patient's head and preventing the headrest 11 from collapsing due to contact with the patient's head, thus improving the safety of the operation. At the same time, the buffer 40 may deform to disperse pressure, ensuring normal blood flow in the tissues of the patient's head and preventing pressure sores from forming on the patient's head due to prolonged surgery, thus reducing the risk of pressure sores on the patient's head.

[0039] It is understandable that the buffer 40 can be a latex block with a honeycomb hollow structure, which can improve the elastic deformation capacity of the buffer 40, thereby improving the pressure dispersion effect, ensuring normal blood flow in the tissues of the patient's occipital region, preventing pressure sores from forming in the patient's occipital region due to prolonged surgery, and reducing the risk of pressure sores in the patient's occipital region.

[0040] like Figure 1 and Figure 4As shown, in some embodiments, two adjacent protective pads 12 can define an avoidance notch 112, which can communicate with the headrest cavity to avoid the patient's shoulders and neck, and ensure that the patient's head is inserted into the headrest cavity of the headrest pad 11, thereby ensuring the normal use of the head and shoulder pads and facilitating the restriction of the patient's head and neck, which can improve the safety of the operation.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the head and shoulder pillow 100 may further include a shoulder pillow pad 13, which may be disposed on the side of the head pillow pad 11 near the avoidance notch 112, so that the patient's neck and shoulders can contact the upper surface of the shoulder pillow pad 13, which can distribute the pressure on the patient's neck and shoulders, ensure normal blood flow in the tissues of the patient's neck and shoulders, prevent pressure sores from forming on the patient's neck and shoulders due to prolonged surgery, and reduce the risk of pressure sores forming on the patient's neck and shoulders.

[0042] The shoulder pillow pad 13 may have a third cavity (not shown in the figure), which can communicate with the first cavity, so that the heat exchange medium can flow along the vent pipe 24 through the head pillow pad 11 and the shoulder pillow pad 13. This can increase the flow range of the heat exchange medium in the pillow pad 10, improve the heat exchange effect of the heat exchange medium, improve the heat preservation effect on the patient's head and neck, and prevent the patient from having abnormal body temperature due to prolonged surgery. At the same time, the shoulder pillow pad 13 and the head pillow pad 11 can be dynamically inflated and deflated together, so that the shoulder pillow pad 13 can deform to distribute pressure, ensure normal blood flow in the tissues of the patient's neck and shoulders, prevent pressure sores from forming in the patient's neck and shoulders due to prolonged surgery, and reduce the risk of pressure sores in the patient's neck and shoulders.

[0043] like Figure 4 and Figure 5 As shown, in some embodiments, the shoulder pad 13 can extend downwards in a direction away from the head pad 11, so that the patient's shoulders and neck can fit closely with the shoulder pad 13 of the head and shoulder pillow 100, and can increase the fit between the patient's shoulders and neck and the shoulder pad 13 to distribute pressure, can ensure normal blood flow in the tissues of the patient's shoulders and neck, can prevent the patient's shoulders and neck from developing pressure sores due to prolonged surgery, and can reduce the risk of pressure sores in the patient's shoulders and neck.

[0044] like Figure 1 and Figure 4As shown, in some embodiments, the cross-section of the shoulder pillow 13 can gradually increase in the direction away from the head pillow 11, which can increase the contact area between the patient's shoulder and neck and the shoulder pillow 13, and increase the contact range between the patient's shoulder and neck and the shoulder pillow 13, thereby dispersing pressure, ensuring normal blood flow in the tissues of the patient's shoulder and neck, preventing pressure sores from forming in the patient's shoulder and neck due to prolonged surgery, and reducing the risk of pressure sores in the patient's shoulder and neck.

[0045] like Figure 1 and Figure 4 As shown, in some embodiments, the head and shoulder pillow 100 may further include: Velcro (not shown in the figure), which may have a hook side (not shown in the figure) and a loop side (not shown in the figure). In two adjacent protective pads 12, the hook side may be disposed on one protective pad 12 and the loop side may be disposed on the other protective pad 12. The hook side and the loop side may be bonded together to connect the two adjacent protective pads 12, so that multiple protective pads 12 can cooperate to wrap the patient's head and back, which can improve the protective effect on the patient's head and back, reduce the exposed area of ​​the patient's head and back, improve the heat preservation effect on the patient's head and back, and prevent the patient from having abnormal body temperature due to prolonged surgery.

[0046] like Figures 1-5 As shown, according to some embodiments of the present invention, the control assembly 20 further includes: a control box 21, an inlet pipe 22, an outlet pipe 23, and a vent pipe 24. The control box 21 may define a control cavity (not shown in the figure). The first pump body and the second pump body may be disposed in the control cavity. One end of the inlet pipe 22 may be connected to one end of the water pipe 30, and one end of the outlet pipe 23 may be connected to the other end of the water pipe 30. The other ends of the inlet pipe 22 and the other ends of the outlet pipe 23 may be connected to the first pump body in the control cavity, respectively.

[0047] This allows the first pump to drive the heat exchange medium to circulate sequentially through the inlet pipe 22, the outlet pipe 30, and the outlet pipe 23 to keep the patient's head and neck warm. One end of the vent pipe 24 can be connected to the inner cavity, and the other end of the vent pipe 24 can be connected to the second pump, allowing the second pump to pump air into the inner cavity (such as the first, second, and third cavities) through the vent pipe 24 to achieve dynamic inflation and deflation of the entire headrest pad 11, which can reduce the risk of pressure sores on the patient's head and neck.

[0048] In some embodiments, a water tank (not shown in the figure) may also be provided inside the control cavity. The water tank is detachably disposed between the first pump body and the outlet pipe 23. For example, the water tank can be snapped into the inner wall of the control box 21, and the outlet pipe 23 and the outlet of the first pump body can be respectively inserted into the water tank, so that the outlet pipe 23 can be connected to the first pump body through the water tank. Thus, the first pump body can drive the heat exchange medium in the water tank to circulate sequentially through the inlet pipe 22, the water pipe 30 and the outlet pipe 23 to achieve heat preservation for the patient's head and neck. This facilitates the replacement of the heat exchange medium, facilitates maintenance, can improve the service life of the head and shoulder pillow 100, and is conducive to increasing the flow of the heat exchange medium, which is conducive to improving the heat preservation effect on the patient's head and neck.

[0049] In some embodiments, the control component 20 may further include a heater (not shown in the figure), which may be disposed in a water tank. The heater can heat the heat exchange medium, thereby enabling the temperature regulation of the heat exchange medium, improving the stability of heat exchange, enhancing the heat exchange effect of the heat exchange medium, improving the heat insulation effect on the patient's head and neck, and preventing the patient from experiencing abnormal body temperature due to prolonged surgery.

[0050] It is understood that the control component 20 may also include a temperature controller (not shown in the figure). The temperature controller can detect the temperature of the heat exchange medium in the controller and control the heater to work according to its temperature, thereby realizing the control of the temperature of the heat exchange medium. The control box 21 may have multiple adjustment buttons (not shown in the figure). Different adjustment buttons can control the work of different components to achieve different functions. For example, the adjustment buttons can control the working power of the first pump and the second pump. The adjustment buttons can control the heater to work through the temperature controller to adjust the temperature of the heat exchange medium. The control component 20 may also include a battery (not shown in the figure) to store electrical energy, which is beneficial to the normal use of the head and shoulder pillow 100 and can improve the convenience of using the head and shoulder pillow 100.

[0051] According to some embodiments of the present invention, the pillow 10 is entirely sealed and hollow. The inner layer of the pillow 10 (not shown in the figure) may include a waterproof layer, a heat insulation layer and a tear-resistant layer. The waterproof layer can be made of PEV material, which can improve the waterproof performance of the pillow 10. The heat insulation layer can be made of polyester fiber material, which can improve the heat insulation performance of the pillow 10. The tear-resistant layer can be made of nylon material, which can improve the service life of the pillow 10. The outer layer of the pillow 10 (not shown in the figure) can be made of soft suede material, and the outer layer and the inner layer can be connected by Velcro to facilitate the replacement of the suede material of the outer layer and facilitate maintenance.

[0052] Other configurations and operations of the head and shoulder pillow 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here. In the description of the present invention, "first feature" and "second feature" may include one or more of the features.
