Detailed implementation manners
[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] The embodiment of the cold compress ice bag that is convenient to fix is as follows:
[0030] Please refer to Figures 1-9 , a cold compress ice bag that is convenient to fix, including a fixed outer shell 1 and a cold compress layer 2 placed inside it. The fixed outer shell 1 consists of a knee part, a lower limb part, and an upper limb part. The cross-section of the fixed outer shell 1 is in the shape of an "n", which is used to fit the knee joint of a patient. The fixed outer shell 1 is made of an elastic and deformable material, which is convenient to wrap the cold compress ice bag around the knee joint. The bottom of the lower limb part and the upper limb part of the fixed outer shell 1 are both provided with restraint belts 9, and the surface of the restraint belts 9 is provided with Velcro, which is used to fix the cold compress ice bag at the knee joint of the patient.
[0031] Inside the cold compress layer 2, there are arranged a cold compress material cavity 3 and a partition cavity 4. When using the cold compress material inside the cold compress material cavity 3 to perform cold compress on the patient's knee joint, the thickness of the partition cavity 4 decreases and it fits against the patient's skin through the contact layer 201 at the bottom of the cold compress layer 2. Filling the partition cavity 4 with heat insulation material is used to relieve the low-temperature cold compress of the cold compress material inside the cold compress material cavity 3 on the patient's knee joint. Among them, the cold compress material can be cold gel or superabsorbent resin, the heat insulation material is in liquid state and can be hydrogel or biogel, and the contact layer 201 is made of latex material, which can not only increase the comfort of its fitting against the patient's skin, but also prevent skin frostbite.
[0032] It should be noted that an air cavity 5 is arranged inside the cold compress layer 2. The air cavity 5 is located on the side of the cold compress material cavity 3 away from the partition cavity 4. An air pump 10 is installed on the outer side of the fixed housing 1 to adjust the air pressure inside the air cavity 5.
[0033] On this basis, a number of second sealing cylinders 8 are arranged in the cold compress material cavity 3. The upper end of the second sealing cylinder 8 is communicated with the air cavity 5, and the lower end is communicated with the partition cavity 4. A piston rod 801 is hermetically and slidably installed inside the second sealing cylinder 8. When the air pressure inside the air cavity 5 decreases, under the action of the pressure difference, the piston rod 801 moves upward, thereby sucking the heat insulation material in the partition cavity 4 into the second sealing cylinder 8, so as to reduce the heat insulation effect of the partition cavity 4, so that the cold compress material in the cold compress material cavity 3 can perform cold compress on the patient's knee joint. When the air pressure inside the air cavity 5 increases, the piston rod 801 pushes the heat insulation material in the second sealing cylinder 8 into the partition cavity 4 to increase the heat insulation effect of the partition cavity 4, so as to relieve the low-temperature cold compress of the cold compress material inside the cold compress material cavity 3 on the patient's knee joint.
[0034] On this basis, it also includes that a plurality of inner grooves 202 are arranged on the bottom surface of the contact layer 201. A suction rod 7 is installed in the inner groove 202. A suction cup 701 is installed at the bottom end of the suction rod 7, and the suction cup 701 is adapted to the inner groove 202.
[0035] A number of first sealing cylinders 6 are installed inside the cold compress material cavity 3. The upper end of the first sealing cylinder 6 is communicated with the air cavity 5. The suction rod 7 is hermetically and slidably installed in the corresponding first sealing cylinder 6. A piston plate 702 is fixedly arranged at the upper end of the suction rod 7. The piston plate 702 is hermetically and slidably connected with the first sealing cylinder 6. The inside of the suction rod 7 is an air passage.
[0036] When the air pressure inside the air cavity 5 decreases, the suction cup 701 can adsorb on the patient's skin surface, and at the same time, it is convenient for the cold compress layer 2 to approach the patient's skin until the contact layer 201 fits against the patient's skin, so as to improve the cold compress effect of the cold compress layer 2 on the patient's knee joint.
[0037] It should be noted that a spherical cavity 703 is provided inside the airway. A blocking plate 704 and a slideway 705 are provided inside the spherical cavity 703. A magnetic support rod 706 is slidably installed inside the slideway 705. The lower end of the support rod 706 is fixedly connected to the blocking plate 704, and an electromagnetic coil 707 is installed on one side of the other end.
[0038] By setting the activation condition of the electromagnetic coil 707, that is, when the air pressure inside the airway drops to a set value, the electromagnetic coil 707 is activated, generating an adsorption force on the support rod 706. Then, the blocking plate 704 is driven by the support rod 706 to move upward until the blocking plate 704 cooperates with the inner wall of the spherical cavity 703. On this basis, when the air pressure inside the airway continues to drop, the blocking plate 704 tightly cooperates with the inner wall of the spherical cavity 703, and the air pressure inside the suction cup 701 no longer changes, and the suction cup 701 maintains a constant-pressure adsorption on the patient's skin. After that, the piston plate 702 will move inside the first sealing cylinder 6 under the action of air pressure. At the same time, under the continuous reduction of the air pressure inside the air cavity 5, the piston rod 801 moves upward, sucking the heat-insulating material inside the partition cavity 4 into the second sealing cylinder 8.
[0039] It should also be noted that the fixed outer shell 1 and the cold compress layer 2 are connected by a plurality of spring members 101. The spring members 101 are used to keep the cold compress layer 2 and the fixed outer shell 1 elastically connected. After the suction cup 701 adsorbs the patient's skin, the piston plate 702 moves upward, pulling the cold compress layer 2 closer to the patient's skin, thereby promoting the cooperation between the suction cup 701 and the inner groove 202, and the contact layer 201 fits with the patient's skin; when the air pressure in the suction cup 701 increases, the suction cup 701 presses tightly against the patient's skin, and the piston plate 702 moves downward inside the first sealing cylinder 6, causing the cold compress layer 2 to move away from the patient's skin, so as to further relieve the low-temperature cold compress of the cold compress material inside the cold compress material cavity 3 on the patient's knee joint.
[0040] The working principle of this cold compress ice bag:
[0041] First, wrap this cold compress ice bag around the patient's knee joint, fix this cold compress ice bag on the patient's knee joint using the restraint strap 9, and then start the air pump 10 to reduce the air pressure inside the air cavity 5 using the air pump 10.
[0042] After the air pressure inside the air cavity 5 drops, the suction cup 701 will generate an adsorption effect on the patient's skin and adhere to the patient's skin surface until the blocking plate 704 cooperates with the spherical cavity 703. On this basis, the piston plate 702 moves upward under the action of air pressure, thereby promoting the contact layer 201 to fit with the patient's skin.
[0043] After the air pressure inside the air cavity 5 drops, the piston rod 801 moves upward inside the second sealing cylinder 8 and sucks the heat-insulating material inside the partition cavity 4 into the second sealing cylinder 8, facilitating the cold compress material inside the cold compress material cavity 3 to perform cold compress on the patient.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
