Abstract
Description
Technical Field
[0001] This utility model relates to the field of ice cap technology, specifically a medical ice cap for use after craniocerebral trauma surgery. Background Technology
[0002] Traumatic brain injury is often accompanied by cerebral edema, leading to increased intracranial pressure. Ice caps, through their cooling effect, can reduce cerebral edema, thereby helping to control intracranial pressure to some extent and prevent further brain damage. Furthermore, in a hypothermic environment, the immune system and inflammatory response are suppressed to some extent, which helps reduce secondary damage to brain tissue. Hypothermia can reduce the migration and activation of white blood cells, thereby reducing the release of inflammatory factors and further protecting brain tissue.
[0003] Currently used ice caps generally use ice blocks or circulating water for cooling. For example, in a medical ice cap for post-traumatic brain injury surgery with patent number CN221384012U, a cooling unit is set up so that the cooling water inside the cooling chamber can circulate and evenly cool the patient's head when used in conjunction with a battery pack, a micro water pump, a water suction pipe, and a water delivery pipe. This avoids the problem of the ice cap not fitting well to the patient's head due to the irregular shape of the ice blocks, which would prevent the ice cap from cooling the patient's head evenly. This improves the practicality of the ice cap.
[0004] However, during use, whether ice or circulating water is used for cooling, a certain weight will be generated in the ice cap. When the patient wears it in a sitting position, it will cause pressure on the postoperative wound, which may cause discomfort and affect comfort. Utility Model Content
[0005] The purpose of this invention is to provide a medical ice cap for use after craniocerebral trauma surgery, which solves the problem in the background art that the ice cap plus the internal cooling medium has a certain weight, which may cause pressure on the postoperative wound when the patient wears it in a sitting position, resulting in discomfort and affecting comfort.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a medical ice cap for use after craniocerebral trauma surgery, comprising an ice cap body and a compression plate, wherein a plurality of hooks are fixedly connected to the top edge of the ice cap body, the hooks are movably connected to the hanging rope, a cooling layer is provided on the inner side of the ice cap body, double-sided adhesive is pasted on the top surface of the compression plate, and the compression plate is pasted to the inner surface of the ice cap body by the double-sided adhesive, and a buffer layer is movably connected to the inner surface of the ice cap body.
[0007] In this technical solution, the lanyard is hung in a suitable place, such as on an IV stand, and the length of the lanyard is adjusted according to the patient's own comfort, thereby reducing the pressure of the ice cap body on the patient's head and improving comfort. Before use, the compression plate is attached to the inner surface of the ice cap body according to the location of the patient's head wound. At this time, the compression plate body will push up part of the cooling layer, and then a buffer layer is inserted for shielding. When the patient wears the ice cap body, the cooling layer at the compression plate position will not directly contact the head or will reduce the contact area, thereby reducing the pressure of the cooling layer on the head wound.
[0008] Preferably, the outer surface of the ice cap body is provided with an ice filling port, which is connected to the cooling layer and is provided with a sealing cap.
[0009] Preferably, the surface of the ice cap body is sealed with a plurality of semiconductor cooling chips, the interior of the semiconductor cooling chips is located inside the cooling layer, and the contact edge between the cooling layer and the semiconductor cooling chips is sealed.
[0010] Preferably, the cooling layer is connected to one end of both the outlet pipe and the inlet pipe, and the other ends of the outlet pipe and the inlet pipe are connected to the outlet end and the inlet end of the water pump, respectively.
[0011] Preferably, a Velcro fastener is fixedly attached to the bottom edge of the ice cap body.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model provides a hook and a hanging rope at the top of the ice cap body. When the patient uses the ice cap body in a seated position, the hanging rope can be hung in a suitable place, such as an IV stand, and the length of the hanging rope can be adjusted according to the patient's own comfort, thereby reducing the pressure of the ice cap body on the patient's head and improving comfort.
[0014] 2. This utility model, by setting up a squeezing disc and a buffer layer, allows the squeezing disc to be attached to the inner surface of the ice cap body according to the location of the patient's head wound before use. At this time, the squeezing disc body will push up part of the cooling layer. Then, the buffer layer is inserted to cover it. When the patient wears the ice cap body, the cooling layer at the squeezing disc position will not directly contact the head wound or will reduce the contact area, thereby reducing the pressure of the cooling layer on the head wound and improving the actual user experience.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.
[0021] A medical ice cap for use after traumatic brain injury surgery, see [link to relevant documentation]. Figures 1 to 3 The device includes an ice cap body 1 and a compression plate 10. Several hooks 2 are fixedly connected to the top edge of the ice cap body 1. The hooks 2 are movably connected to a hanging rope 3, which can hold the ice cap body 1 and its length can be adjusted according to the patient's comfort, thereby reducing the pressure of the ice cap body 1 on the patient's head. A cooling layer 8 is provided on the inner side of the ice cap body 1. Double-sided tape 11 is attached to the top surface of the compression plate 10, and the compression plate 10 is attached to the inner surface of the ice cap body 1 via the double-sided tape 11. The inner surface of the ice cap 1 is connected to a buffer layer 7. The buffer layer 7 is a cap-shaped cover supported by soft material, which is adapted to the inner surface of the ice cap body 1. Its main function is to block and buffer the compression plate 10 to prevent the compression plate 10 from hitting the head because it is too hard. The compression plate 10 body will push up part of the cooling layer 8, and then insert the buffer layer 7 to block it. When the patient wears the ice cap body 1, the cooling layer 8 at the compression plate 10 position will not directly contact the wound, reducing the pressure of the cooling layer 8 on the head wound.
[0022] Specifically, such as Figure 2 As shown, the outer surface of the ice cap body 1 is provided with an ice filling port 9. The ice filling port 9 is connected to the cooling layer 8 and is provided with a sealing cover. Ice can be added to the ice filling port 9 to increase the cooling effect. This allows the ice cap body 1 to be cooled by either circulating water or ice, so that it can still be cooled when there is no power, thus improving its adaptability and practicality.
[0023] It is worth noting that, such as Figure 1 and Figure 2As shown, the surface of the ice cap body 1 is sealed with several thermoelectric coolers 5. The interior of the thermoelectric coolers 5 is located inside the cooling layer 8, and the contact edge between the cooling layer 8 and the thermoelectric coolers 5 is sealed. The thermoelectric coolers 5 operate based on the Peltier effect. They are composed of alternating N-type and P-type semiconductor materials connected in series to form a thermopile. When direct current passes through the thermoelectric coolers 5, the current generates a temperature difference effect at the contact point between the N-type and P-type semiconductor materials, thereby achieving a cooling or heating effect. Specifically, when current passes through the thermoelectric coolers 5, the cold end absorbs heat and lowers the temperature, while the hot end releases heat and raises the temperature. By adjusting the direction and magnitude of the current, the cooling or heating effect and temperature range of the thermoelectric coolers 5 can be controlled. This is a mature existing technology, and it is used directly here without functional modification.
[0024] It is worth noting that, such as Figure 2 As shown, the cooling layer 8 is connected to one end of the water outlet pipe 601 and the water inlet pipe 602. The other ends of the water outlet pipe 601 and the water inlet pipe 602 are connected to the water outlet end and the water inlet end of the water pump 6, respectively. After the water pump 6 is connected to an external power source, it circulates the water in the cooling layer 8 through the water inlet pipe 602 and the water outlet pipe 601, thereby improving the heat dissipation effect and the cooling efficiency.
[0025] It is worth noting that, such as Figure 1 As shown, Velcro 4 is fixedly connected to the bottom edge of the ice cap body 1. The opening at the bottom of the ice cap body 1 can be increased or decreased by Velcro 4 to adapt to different head sizes of patients.
[0026] In actual use, by setting a hook 2 and a hanging rope 3 at the top of the ice cap body 1, when the patient uses the ice cap body 1 in a seated position, the hanging rope 3 can be hung in a suitable place, such as an IV stand. The hanging rope 3 can hold the ice cap body 1, and the length of the hanging rope 3 can be adjusted according to the patient's own comfort, thereby reducing the pressure of the ice cap body 1 on the patient's head and improving comfort. Before use, according to the location of the patient's head wound, the compression plate 10 is attached to the inner surface of the ice cap body 1. At this time, the compression plate 10 body will push up part of the cooling layer 8, and then the buffer layer 7 is inserted for shielding. When the patient wears the ice cap body 1, the cooling layer 8 at the compression plate 10 position will not directly contact the head or will reduce the contact area, reducing the pressure of the cooling layer 8 on the head wound and improving the actual user experience.
