[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0037] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "inner" and "outer" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present application. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "arrangement" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0039] An embodiment of the present application provides a cap-type airbag pressurization device for after craniotomy, including a cold compress member 100, an airbag headgear 200, and a fixing member 300.

[0040] As Figure 4 shown, the cold compress member 100 is arranged on the patient's head. The inner wall of the cold compress member 100 is an arc-shaped curved wall adapted to the contour of the patient's head. The cold compress member 100 can press the wound on the patient's head. The inner wall of the cold compress member 100 is convenient for adapting to the contour of the patient's head and can better fit the curved surface of the patient's head, and then can fully press the wound on the patient's head to ensure the dressing effect.

[0041] Exemplarily, in one embodiment, the cold compress member 100 is made of a paraffin-based phase change material or a material such as a steel plate to extend the low-temperature time of the cold compress member 100.

[0042] Exemplarily, in one embodiment, a silver ion-containing antibacterial gel layer is provided on the surface of the cold compress member 100. The silver ion-containing antibacterial gel layer provided on the surface of the cold compress member 100 has an antibacterial effect and helps to reduce the risk of wound infection.

[0043] The airbag headgear 200 is sleeved on the cold compress member 100. Exemplarily, the cold compress member 100 and the airbag headgear 200 are detachably connected by means of Velcro, gluing, snap connection, magnetic attraction, etc. The airbag headgear 200 can apply a force to the cold compress member 100 and can make the cold compress member 100 better fit the wound.

[0044] When the airbag headgear 200 is inflated and expanded, it can push the cold compress member 100. After being pushed, the cold compress member 100 moves closer to the patient's head direction to press the wound.

[0045] As Figure 1 shown, the fixing member 300 is disposed on the airbag headgear 200, and the fixing member 300 is used to fix the airbag headgear 200 on the patient's head, ensuring the stability and safety of the device.

[0046] The airbag headgear 200 includes at least two sub-airbags 210, and adjacent sub-airbags 210 are connected to each other, and different sub-airbags 210 can be inflated independently. Exemplarily, the airbag headgear 200 includes two sub-airbags 210. In another embodiment, the airbag headgear 200 includes three sub-airbags 210. However, in some other embodiments, the airbag headgear 200 can also be provided with other numbers, such as four, five, six or seven, etc.

[0047] Exemplarily, the inner wall of the cold compress member 100 is configured as an arc-shaped curved wall adapted to the arc-shaped contour of the patient's head, and the outer wall of the cold compress member 100 is configured as an arc-shaped curved wall adapted to the inner wall. As Figure 1 , Figure 2 or Figure 4 shown, the inner wall of the airbag headgear 200 is configured as an arc-shaped curved wall adapted to the outer wall of the cold compress member 100, such as a helmet-like structure. However, in another embodiment, as long as the cold compress member 100 can be fixed on the patient's head, the airbag headgear 200 can also be configured in other shapes, such as a ring structure sleeved on the cold compress member 100, and adjacent sub-airbags 210 are connected end to end to form a ring structure.

[0048] During use, when it is necessary to inflate the target sub-airbag 210, the adjacent sub-airbags 210 can be inflated adaptively at the same time, so that the surrounding sub-airbags 210 can adapt to the deformation of the target sub-airbag 210.

[0049] The head sizes of different patients are different. Therefore, inflating different sub-airbags 210 can cause specific areas of the airbag headgear 200 to expand, and further enable the headgear airbag and the cold compress member 100 to adapt to different patients, increasing adaptability. Moreover, the independently inflatable sub-airbags 210 can pressurize the patient's wound. For example, when there is a wound at the back of the patient's head, only the sub-airbag 210 corresponding to the back of the patient's head needs to be inflated, and it is not necessary to inflate the sub-airbags 210 at other positions, which can improve the efficiency and effect of wound compression.

[0050] As Figure 3 and Figure 4 shown, in one embodiment, the cold compress member 100 includes at least one sub-block 110. When the number of sub-blocks 110 is at least two, adjacent sub-blocks 110 are connected to each other to form a cold compress member 100 adapted to the arc-shaped contour of the patient's head.

[0051] Exemplarily, the cold compress member 100 includes two sub-blocks 110. In another embodiment, the cold compress member 100 includes three sub-blocks 110. In another embodiment, the cold compress member 100 includes four sub-blocks 110. In another embodiment, the cold compress member 100 includes five sub-blocks 110. Of course, in some other embodiments, the cold compress member 100 may also include other numbers of sub-blocks 110. Such as six, seven or eight, etc. These sub-blocks 110 are distributed according to the arc-shaped surface of the human head.

[0052] During use, the number and position of the sub-blocks 110 can be configured according to the size of the wound. For example, when there is a small area wound at the back of the patient's head, two sub-blocks 110 can be used to cover the patient's wound at the corresponding position of the wound at the back of the patient's head. These two sub-blocks 110 are detachably connected and form a curved surface structure adapted to the curvature of the back of the patient's head. For another example, when there is a larger wound on the side of the patient's head, four to five sub-blocks 110 can be used to cover the wound at the corresponding position on the side of the patient's head.

[0053] In one embodiment, when the number of sub-blocks 110 is at least two, the connection manner between adjacent sub-blocks 110 is, for example, a detachable fixed connection. The detachable fixed connection is, for example, a snap connection, a magnetic connection, a Velcro connection or an adhesive connection, etc., which is convenient for adjusting the size and shape of the cold compress member 100 to adapt to the positions and sizes of different wounds.

[0054] To ensure ventilation and air permeability at the patient's wound, as Figure 2 shown, in one embodiment, the sub-airbag 210 is provided with a ventilation structure 220.

[0055] The design of the ventilation through-holes allows air to flow freely between the cold compress member 100 and the patient's wound, which helps to keep the wound dry and clean and reduces the risk of infection. Good air permeability helps to reduce the growth of bacteria at the wound and lower the risk of infection, thus creating a more favorable environment for wound healing.

[0056] Exemplarily, as Figure 2 shown, the ventilation structure 220 is an array of ventilation through-holes. The inner wall of the ventilation through-hole penetrates the sub-airbag 210. The air pressure is maintained inside the sub-airbag 210 and the sub-airbag 210 maintains ventilation and air permeability. In some other embodiments, the ventilation structure 220 is a hollow protrusion provided on the inner surface of the sub-airbag 210. The hollow protrusion keeps a ventilation gap between the inner wall of the sub-airbag 210 and the cold compress member 100. And, the inner wall design of the air through-hole can better support the sub-airbag 210, help it maintain its shape, and improve the strength of the sub-airbag 210.

[0057] In one embodiment, the breathable structure 220 is a breathable through-hole, and a first fan assembly is provided on the inner wall of the breathable through-hole. When the first fan assembly rotates, it can make the air flow at the breathable through-hole, thereby accelerating the air flow between the cold compress 100 and the patient's wound, so as to improve the breathability. A first fan assembly can include at least one fan blade. When there are two or more fan blades, the fan blades can be distributed side by side or stacked.

[0058] In another embodiment, the breathable structure 220 is a breathable through-hole, and a second fan assembly is provided on the sub-airbag 210 near the breathable through-hole. The second fan assembly is located outside the breathable through-hole. When the second fan assembly is activated, it can blow the outside air into the breathable through-hole, thereby accelerating the air flow between the cold compress 100 and the patient's wound, so as to improve the breathability.

[0059] Exemplarily, a second fan assembly can correspond to one breathable through-hole or two or more breathable through-holes. A first fan assembly can include at least one fan blade. When there are two or more fan blades, the fan blades can be distributed side by side or stacked.

[0060] The setting of the first fan assembly or the second fan assembly further improves the breathability of the cold compress 100 by accelerating the air flow at the breathable through-hole. This helps to accelerate the air exchange at the wound and promote wound healing. The accelerated air flow can also take away the heat and moisture at the wound, helping to reduce swelling and pain, promoting wound healing, and also helping the cold compress 100 to distribute the cooling effect more evenly, improving the comfort and effect of cold compress. The improvement of breathability helps to reduce the stuffy feeling at the patient's wound and improve the patient's comfort.

[0061] In some embodiments, before use, the sub-block 110 is placed in a low-temperature environment to keep the sub-block 110 at a low temperature, and then the sub-block 110 is taken out of the low-temperature environment during use, so as to obtain the cold compress 100 at a low temperature for covering the wound.

[0062] Different from the situation where the sub-block 110 is placed in a low-temperature environment in the above embodiments, in one embodiment, a cooling chamber is provided in the sub-block 110, and a cooling medium is stored in the cooling chamber. The cooling medium is, for example, low-temperature liquid water, ice cubes, low-temperature ethanol, etc. The low temperature is a temperature lower than the human body temperature or close to zero degrees Celsius.

[0063] Different from the case where the cooling chamber stores static cooling medium in the above embodiments, in one embodiment, a cooling assembly is connected to the cooling chamber of the sub-block 110, and the cooling assembly circulates and supplies a cooling medium into the cooling chamber. An inlet and an outlet are provided on the sub-block 110. The cooling assembly is communicated with the inlet and the outlet. The cooling assembly supplies the cooling medium from the inlet into the cooling chamber. The cooling medium flows in the cooling chamber to cool the sub-block 110. The heat at the patient's wound is conducted to the sub-block 110 and the cooling medium, causing the cooling medium to heat up. The cooling medium in the cooling chamber flows back to the cooling assembly from the outlet, so that the cooling assembly can continuously cool the flowing-back cooling medium and supply it back to the cooling chamber again. The cooling medium in the cooling chamber remains at a low temperature, so that the sub-block 110 remains at a low temperature to ensure the cold compress effect of the cold compress piece 100. This continuous low-temperature environment is crucial for reducing swelling, pain and inflammation at the wound, and helps to accelerate the wound healing process. The cooling medium is evenly distributed in the cooling chamber, so that the entire surface of the sub-block 110 can remain at a low temperature, thereby providing a uniform cold compress effect. This helps to avoid local overheating or overcooling and improves the comfort of the patient.

[0064] Through the design of circulating and supplying the cooling medium by the cooling assembly, the recycling of the cooling medium can be realized. The cooling medium absorbs heat in the cooling chamber and then flows back to the cooling assembly for cooling, and then is supplied back to the cooling chamber again. This design not only saves the cooling medium, but also reduces the use cost.

[0065] The cooling assembly is, for example, a compressor, and the cooling medium is, for example, freon, hydrochlorofluorocarbon, hydrofluorocarbon, difluoromethane, etc. In another embodiment, the cooling assembly is, for example, an air-cooled machine, and the cooling medium is, for example, water or alcohol, etc.

[0066] By providing a cooling chamber in the sub-block 110 and storing the cooling medium, or by circulating and supplying the cooling medium by the cooling assembly, it can be ensured that the sub-block 110 remains in a low-temperature state. This design enables the cold compress piece 100 to continuously provide a low-temperature environment, effectively reducing swelling, pain and inflammation at the patient's wound and improving the cold compress effect.

[0067] Compared with the method of pre-cooling the sub-block 110 by placing it in a low-temperature environment, the design of the built-in cooling chamber or the connected cooling assembly makes the use of the cold compress piece 100 more convenient. When in use, there is no need to prepare a low-temperature environment in advance, and it can be directly taken out or used, greatly improving the flexibility and convenience of use.

[0068] In one embodiment, the cooling chambers of adjacent sub-block bodies 110 are in communication. Therefore, when two or more sub-block bodies 110 are provided, only one cooling component needs to be configured for use. That is, when multiple sub-block bodies 110 are required to form a larger cold compress piece 100, the communication of the cooling chambers of adjacent sub-block bodies 110 means that only one cooling component needs to be configured to provide a cooling effect for all sub-block bodies 110. This design greatly simplifies the configuration of the cooling system and reduces the number and cost of cooling components.

[0069] The communication of the cooling chambers enables the cooling medium to flow freely between multiple sub-block bodies 110, thereby improving the cooling efficiency. The cooling medium can be more evenly distributed in each sub-block body 110 to ensure that each sub-block body 110 can obtain sufficient cooling effect.

[0070] Exemplarily, the sub-block body 110 is provided with a plug nozzle for communicating the cooling chamber. The plug nozzle of one sub-block body 110 is connected to the plug nozzle of an adjacent another sub-block body 110, so that the cooling chambers of adjacent sub-block bodies 110 are communicated through the plug nozzles.

[0071] However, in another embodiment, the plug nozzles of adjacent sub-block bodies 110 are communicated through a pipeline.

[0072] By connecting the cooling chambers of adjacent sub-block bodies 110 through plug nozzles or pipelines, doctors or patients can freely combine the number and arrangement of sub-block bodies 110 according to needs. This flexibility enables the cold compress piece 100 to adapt to wounds of different sizes, shapes and positions, improving the convenience and applicability of use.

[0073] The plug nozzle is provided with a lid. When the plug nozzle is not needed, the lid can close the plug nozzle to prevent the leakage of the cooling medium. This design improves the sealing performance and safety, avoiding potential risks caused by the leakage of the cooling medium.

[0074] In one embodiment, adjacent sub-airbags 210 are detachably connected. The detachable connection methods are, for example, adhesive bonding, Velcro connection, snap connection or magnetic connection, etc.

[0075] Different from the above disassembly connection methods, as Figure 2 shown, in one embodiment, the sub-airbag 210 is provided with a mating protrusion 230 and a mating groove 240. The mating protrusion 230 of the sub-airbag 210 is snap-fitted with the mating groove 240 of an adjacent another sub-airbag 210, and the mating groove 240 of the sub-airbag 210 is snap-fitted with the mating protrusion 230 of an adjacent another sub-airbag 210.

[0076] The two ends of the mating protrusion 230 are respectively a first end portion 250 close to the sub-airbag 210 and a second end portion 260 far from the sub-airbag 210. The size H1 of the first end portion 250 is smaller than the size H2 of the second end portion 260. The dimension direction is along the extension direction 400 of the sub-airbag, and the mating protrusion 230 forms a trapezoidal structure; the inner wall of the mating groove 240 matches the mating protrusion 230, and the mating protrusion 230 forms a trapezoidal groove structure.

[0077] Through the snap-fit of the mating protrusion 230 and the mating groove 240, a stable connection can be formed between adjacent sub-airbags 210. This snap-fit method can effectively prevent the relative movement or separation of the sub-airbags 210 during inflation or use, thereby ensuring the structural stability and reliability of the entire airbag system.

[0078] During use, when a drainage tube needs to be set at the wound of the patient, the mating protrusion 230 can be lifted from the mating groove 240, and the drainage tube can be inserted into the airbag headgear 200 from the mating groove 240 and bypass the sub-block 110 to access the patient's wound.

[0079] In one embodiment, a first magnetic member is provided at the side wall of the mating groove 240 for mating with the mating protrusion 230.

[0080] A second magnetic member is provided on the side wall of the mating protrusion 230 for mating with the mating groove 240. The first magnetic member on one sub-airbag 210 is magnetically connected to the second magnetic member on the adjacent other sub-airbag 210, so that the adjacent two sub-airbags 210 form a rotatable connection through the mating groove 240 and the mating protrusion 230.

[0081] Through the magnetic connection of the first magnetic member provided on the mating protrusion 230 and the second magnetic member provided on the mating groove 240, the adjacent two sub-airbags 210 form a rotatable hinge structure, greatly enhancing the flexibility of the airbag headgear 200, enabling medical staff to easily lift or rotate the sub-airbag 210 according to actual needs, and providing a larger operating space for wound treatment. For example, when a drainage tube needs to be set at the wound of the patient, lift one of the sub-airbags 210 to open a channel on the airbag headgear 200, thereby providing a channel for the drainage tube to access the patient's wound. When a drainage tube needs to be set at the patient's wound, medical staff can simply lift one of the sub-airbags 210, thereby opening a channel on the airbag headgear 200. This design makes the access of the drainage tube more convenient and fast, without the need to disassemble or readjust the entire airbag headgear 200, greatly reducing the work burden of medical staff.

[0082] The rotatable sub-airbag 210 is designed to enable the airbag headgear 200 to better adapt to the patient's head shape and movements, reducing patient discomfort caused by the airbag headgear 200 being too tight or in an improper position. At the same time, the access of the drainage tube is also smoother, reducing the pain caused by the compression or friction of the drainage tube.

[0083] In one embodiment, the craniotomy postoperative cap-type airbag pressurization device further includes an inflation assembly for inflating the sub-airbag 210. The inflation assembly includes a gas source and a control member 500. The gas source is connected to the sub-airbag 210 through a pipeline. The control member 500 controls the gas source to supply compressed gas to the sub-airbag 210 through the pipeline. When the control member 500 is turned on, the gas source supplies compressed gas to the sub-airbag 210. When the control member 500 is turned off, the gas source stops supplying compressed gas to the sub-airbag 210.

[0084] Exemplarily, the gas source is an air pump. The air pump fills the sub-airbag 210 with gas through a pipeline. The control member 500 is an air pump switch. The control member 500 controls the on / off of the air pump power supply, thereby controlling the start and stop of the air pump.

[0085] However, in another embodiment, the gas source is a container storing compressed gas. The control member 500 is a valve body. The container is connected to the sub-airbag 210 through a pipeline. The valve body is arranged on the pipeline. When the valve body is opened, the pipeline is opened, so that the container is connected to the sub-airbag 210, and the compressed gas in the container is introduced into the sub-airbag 210. When the valve body is closed, the pipeline is closed, so that the container is disconnected from the sub-airbag 210.

[0086] Exemplarily, in one embodiment, an exhaust valve is provided on the sub-airbag 210, and the gas in the sub-airbag 210 can be discharged through the exhaust valve.

[0087] As Figure 1 and Figure 2 shown, in one embodiment, the control member 500 is arranged on one of the sub-airbags 210. It is convenient for the patient or doctor to operate the control member 500, improving the convenience and efficiency of the operation.

[0088] As Figure 1 shown, in one embodiment, the fixing member 300 includes a mesh bag 310 and a fixing belt 320.

[0089] The mesh bag 310 is sleeved on the airbag headgear 200 to strengthen the connection between the sub-airbags 210. It ensures the stability and integrity of the airbag headgear 200 during wearing, preventing relative movement or separation between the sub-airbags 210, thereby ensuring the continuity and effectiveness of the pressurization treatment.
