Abstract
Description
Technical Field
[0001] This utility model relates to the field of postoperative care technology, and in particular to an ice pack. Background Technology
[0002] Hemodialysis is a crucial treatment for patients with end-stage renal disease. Arteriovenous fistulas (AVFs) serve as their "lifeline," and repeated punctures during dialysis can easily lead to injection failures, causing vascular swelling, pain, and discomfort. This can also result in complications such as thrombosis and fistula occlusion, threatening treatment effectiveness and the patient's quality of life. To reduce vascular swelling caused by hemodialysis, local ice application is an effective method. During ice application, it's necessary to periodically remove the ice from the skin.
[0003] Currently, some ice pack isolation techniques use cylinders or similar methods to detach the ice pack from the skin. The basic principle is to use the extension and retraction of the cylinder to adjust the position of the ice pack cover, thus creating a gap between the ice pack and the skin and preventing direct contact. However, this design has significant drawbacks. Due to the limited volume of the ice pack cover, large cylinders cannot be accommodated; only small cylinders can be used. Based on the principle of pressure fixation, small cylinders have a small force-bearing area but high pressure, which can exert significant pressure on the patient's skin and easily cause discomfort. Furthermore, the limited stroke of small cylinders results in a smaller isolation distance between the ice pack cover and the skin. Additionally, while small cylinders can push the ice pack away from the skin, the ice pack melts during use. The melted liquid, due to gravity, can move the ice pack towards the skin, significantly reducing the isolation effect. Utility Model Content

[0032] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0033] Please see Figures 1 to 2 This application provides an ice pack, including an ice pack cover 1, an air bladder 2, an air pump 3, a strap, and a power source 5. The ice pack cover 1 has a cavity 11 for accommodating the ice pack and a contact surface 12 for adhering to the skin. The air bladder 2 is located on the side of the ice pack cover 1 facing the contact surface 12. The air pump 3 is connected to the air bladder 2 for inflating and deflating the air bladder 2. The strap is connected to the ice pack cover 1, and the power source 5 is electrically connected to the air pump 3.
[0034] Specifically, the ice pack cover 1 has a cavity 11 for accommodating the ice pack. During use, the side of the ice pack cover 1 that contacts the patient's skin is the contact surface 12. The air bladder 2 is located on the side of the ice pack cover 1 facing the contact surface 12, and can be located inside or outside the ice pack cover 1, without limitation, as long as it can isolate the ice pack from the patient's skin. The air pump 3 is connected to the air bladder 2 and is used to inflate and deflate the air bladder 2. Optionally, two air pumps 3 or a bidirectional air pump 3 can be used to effectively control the inflation and deflation of the air bladder 2. The power supply 5 is electrically connected to the air pump 3 to supply power to the air pump 3. The strap is connected to the ice pack cover 1 to effectively fix the ice pack cover 1 to the target area during use.
[0035] It should be noted that because air itself has excellent temperature insulation properties, the flat airbag 2 can also achieve the required isolation effect; that is, the airbag 2 only needs to be flat to achieve the desired effect. Correspondingly, the inflation and deflation of the airbag 2 can be completed quickly using a small air pump 3, making it convenient to carry. In addition, when the straps are already effectively secured, the inflation of the flat airbag 2 will not cause the straps to burst, improving stability.
[0036] The working principle of the above structure:
[0037] The ice pack cover 1's contact surface 12 is aligned with the target skin requiring icing via the straps. An ice pack is then inserted into the cavity 11 of the ice pack cover 1 for icing. When icing needs to be paused, the air pump 3 inflates the air bag 2 with external air. Once inflation is complete, the air pump 3 stops operating. When the air bag 2 is positioned inside the cavity 11 of the ice pack cover 1, the air-filled air bag 2 isolates the ice pack from the contact surface 12; when the ice pack is positioned outside the ice pack cover 1, the air-filled air bag 2 isolates the contact surface 12 from the patient's skin. These two possible configurations effectively stop icing.
[0038] When the ice pack needs to be continued, the air pump 3 extracts the air from the air bag 2. Once the air in the air bag 2 is emptied, the air pump 3 stops working, thereby restoring the heat transfer between the ice pack and the contact surface 12, or restoring the heat transfer between the contact surface 12 and the skin, thus achieving the effect of continuing the ice pack.
[0039] It should be noted that the presence of a small amount of air in the airbag 2 will not affect the heat transfer efficiency between the ice pack and the contact surface 12, or between the contact surface 12 and the skin. Therefore, the air pump 3 does not need to be a very precise air extraction pump, which can further reduce the overall cost of the ice pack. Furthermore, the air pump 3 has a built-in controller, which can control the operation of the air pump 3 via an external button or timer, etc., which are not limited here.
[0040] In some embodiments, the ice pack cover 1 has an opening on the side away from the contact surface 12, and the ice pack cover 1 has a sealing member 13 at the opening for sealing the opening. One side of the sealing member 13 is fixedly connected to the ice pack cover 1, and the other side is provided with a buckle 14, which is detachably connected to the ice pack cover 1.
[0041] Specifically, the ice pack cover 1 has an opening on the side away from the contact surface 12, the size of which is adapted to the size of the ice pack to ensure that the ice pack can be easily inserted or removed. One side of the cap 13 is fixedly connected to the ice pack cover 1, so that the cap 13 can be flipped open and closed without falling off. The other side of the cap 13 has a buckle 14 structure for forming a detachable connection with the ice pack cover 1, which facilitates the sealing of the opening by the cap 13, making it easy to insert and remove the ice pack, and also prevents the ice pack from falling out after it is inserted into the cavity 11.
[0042] In some embodiments, the projected area of the airbag 2 on the contact surface 12 is the same as the area of the contact surface 12.
[0043] Specifically, the projected area of the airbag 2 on the contact surface 12 is the same as the area of the contact surface 12. When the ice pack is placed on the body part requiring treatment, the airbag 2, after inflation, can be evenly distributed between the ice pack and the contact surface 12, or between the contact surface 12 and the skin. Since the projected area of the airbag 2 is the same as the area of the contact surface 12 (i.e., the part of the surface of the ice pack that contacts the skin), this ensures that the contact or isolation between the ice pack and the skin is uniform and consistent. More importantly, it can isolate all the ice and melted liquid inside the ice pack to the side away from the skin, thereby ensuring the isolation effect of the airbag 2 after inflation.
[0044] In some embodiments, both the airbag 2 and the air pump 3 are located inside the ice pack cover 1.
[0045] Specifically, both the airbag 2 and the air pump 3 are located inside the ice pack cover 1. Correspondingly, the airbag 2 is positioned close to the contact surface 12 of the ice pack cover 1. When the ice pack is placed in the cavity 11, the airbag 2 is located between the ice pack and the contact surface 12, thus achieving control over the heat transfer rate from the ice pack to the contact surface 12 without affecting the airbag 2. More importantly, placing both the airbag 2 and the air pump 3 inside the ice pack cover 1 makes the entire device compact, reduces external components, and facilitates user portability and use. Users do not need to worry about the loss or tangling of the air pump 3 or connecting pipes, improving ease of use and reliability. Furthermore, the appearance is cleaner and more professional, enhancing the overall image of the product.
[0046] In some embodiments, the air pump 3 has a first air port and a second air port, the first air port being connected to the outside of the ice pack cover 1 and the second air port being connected to the air bag 2.
[0047] Specifically, the first air inlet is connected to the outside of the ice pack cover 1, and its main function is to draw in air from the outside or expel internal air to the outside. When the airbag 2 needs to be inflated, the air pump 3 draws in air from the outside through the first air inlet; and when the airbag 2 needs to be deflated, the air pump 3 can expel the air inside the airbag 2 to the outside through the first air inlet.
[0048] The second air inlet is connected to the airbag 2 and its function is to serve as an airflow channel to guide or deflect the airflow generated by the air pump 3 into or out of the airbag 2. When the air pump 3 is working, if the airbag 2 is to be inflated, the airflow will enter the airbag 2 through the second air inlet, causing the airbag 2 to expand; conversely, if the airbag 2 is to be deflated, the air inside the airbag 2 will be drawn out through the second air inlet.
[0049] In some embodiments, the ice pack also includes a timer 6, which is electrically connected to a power source 5 and an air pump 3.
[0050] Specifically, the main function of timer 6 is to provide users with an accurate timing reference to control the duration of each ice application. Excessive cold compresses can damage the skin and tissues, while insufficient time may not achieve the desired therapeutic effect. By setting specific time periods, users can ensure that each ice application is performed within the recommended time range. Timer 6 is electrically connected to power supply 5 for power. The counter is electrically connected to air pump 3, providing time information to the controller built into air pump 3 when it needs to be started and stopped at set times.
[0051] In some embodiments, the strap includes a first strap 41 and a second strap 42, which are respectively located at opposite ends of the ice pack cover 1. The first strap 41 has a first connecting portion 411 on the side away from the ice pack cover 1, and the second strap 42 has a second connecting portion 421 on the side away from the ice pack cover 1. The first connecting portion 411 and the second connecting portion 421 are detachably connected.
[0052] Specifically, the straps include a first strap 41 and a second strap 42, which are respectively located at opposite ends of the ice pack cover 1. This structure facilitates the fixation of the ice pack. A first connecting part 411 is located on the side of the first strap 41 away from the ice pack cover 1, and a second connecting part 421 is located on the side of the second strap 42 away from the ice pack cover 1. The detachable connection between the first connecting part 411 and the second connecting part 421 allows for the connection or separation of the first strap 41 and the second strap 42, thereby facilitating the installation and fixation of the ice pack.
[0053] Furthermore, both the first connecting part 411 and the second connecting part 421 are Velcro.
[0054] Specifically, both the first connecting part 411 and the second connecting part 421 are Velcro. Correspondingly, one of the first connecting part 411 and the second connecting part 421 is hook-and-loop Velcro, and the other is loop Velcro, to facilitate the connection between the first connecting part 411 and the second connecting part 421. With the structure of both the first connecting part 411 and the second connecting part 421 being Velcro, the connection can be completed with a simple press, greatly facilitating the use by medical staff, patients, or caregivers.
[0055] In some embodiments, the power supply 5 is electrically connected to a charging port 7, which is located on one side of the ice pack cover 1.
[0056] Specifically, the charging port 7 allows users to charge the built-in power source 5 via an external power source 5 (such as a USB charger, power bank 5, etc.). This allows the ice pack to regain power after its battery is depleted, ensuring that its main functions—operating the air pump 3 and running the timer 6—continue to work.
[0057] In some embodiments, the outer surface of the ice pack cover 1 is a terry cloth.
[0058] Specifically, the outer surface of the ice pack cover 1 is made of terry cloth, which is soft and comfortable to the touch, providing a more comfortable experience when in direct contact with the skin. This can reduce discomfort that may be caused by prolonged contact with hard materials for patients who need to undergo ice pack treatment for a long time.
[0059] More importantly, towels have excellent moisture-absorbing properties, which can absorb condensation or sweat to a certain extent. During the ice pack application process, condensation may form around the ice pack due to temperature differences. Using a towel as the outer layer can help absorb this moisture and prevent streams of condensation from running down the ice pack.
[0060] The above provides a detailed description of an ice pack according to an embodiment of the present utility model. Specific examples have been used to illustrate the principle and implementation of the present utility model. The description of the above embodiments is only for the purpose of helping to understand the ice pack and its core idea. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of the present utility model. Therefore, the content of this specification should not be construed as a limitation of the present utility model.
