[0018] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0019] Example 1: Figure 1-Figure 10As shown, a temperature-adjustable medical ice pillow comprises a pillow body 1 and a soft layer 2, wherein the pillow body 1 is a hollow structure, and the inner cavity of the pillow body 1 is filled with a liquid medium, wherein the liquid medium may be water, ethylene glycol-based coolant, etc., preferably water, and its temperature may be controlled by an external device, and the soft layer 2 is arranged on the top of the pillow body 1, and a plurality of fluid storage bins 4 are fixedly connected to the top surface of the pillow body 1, and the fluid storage bins 4 are distributed in a linear array, and by distributing the fluid storage bins 4 in an array, the required refrigeration parts may be visually viewed, and the parts to be cooled may be visually judged in the form of coordinate points, and the cold compress parts may be accurately controlled, thereby improving the cold compress effect, and the gap between the fluid storage bins 4 is a guide cavity 3, and the guide cavity 3 is connected to the inner cavity of the pillow body 1, and a sealing pad 5 is fixedly connected to the side wall of the guide cavity 3 near the top surface, and the sealing pad 5 is made of rubber and silicone material, and has certain elasticity and sealing performance, and the side walls of the fluid storage bins 4 are located in the guide cavity 3 and are provided with a guide assembly; The bottom surface of the fluid storage bin 4 is provided with a reflux hole 17 , which is communicated with the inner cavity of the pillow body 1 , and a one-way valve 18 is installed in the reflux hole 17 .

[0020] The material of the soft layer 2 can be memory foam, latex, down, polyester fiber, silk, etc.

[0021] The inner cavity of the pillow body 1 is provided with a pressurizing component, and the side surface of the soft layer 2 is provided with a storage component.

[0022] like Figure 1 and Figure 4 As shown, the front and rear side walls of the soft layer 2 are respectively fixedly connected with two Velcro hook surfaces 26, and the front and rear side walls of the pillow body 1 are respectively fixedly connected with two Velcro fleece surfaces 27, and the Velcro hook surface 26 is adapted to the Velcro fleece surface 27. The Velcro hook surface 26 and the Velcro fleece surface 27 can be used to fix the soft layer 2 on the pillow body 1, so as to achieve the purpose of convenient fixing and disassembly. When the cooling position on the pillow body 1 needs to be controlled, the soft layer 2 needs to be opened first, and after pressing the convex block 12 at the designated position, the soft layer 2 needs to be bonded and fixed through the Velcro hook surface 26 and the Velcro fleece surface 27, so as to achieve the purpose of convenient use.

[0023] like Figure 2 and Figure 8 As shown, the flow guide component includes a fixed cylinder 6 fixedly connected to the side wall of the flow storage bin 4, the inner cavity of the fixed cylinder 6 is movably connected with a pressure block 7, the cross-section of the pressure block 7 is stepped, the inner wall of the fixed cylinder 6 is rotatably connected with an elastic rod 8 near the bottom surface, the stepped surface of the pressure block 7 is provided with a positioning groove 10, the positioning groove 10 is fixedly connected with a positioning block 11, the elastic rod 8 is a U-shaped structure, the other end of the elastic rod 8 is inserted into the positioning groove 10, a spring 9 is fixedly connected between the bottom surface of the pressure block 7 and the fixed cylinder 6, the top surface of the sealing gasket 5 is located on the upper side of the pressure block 7 and is fixedly connected with a plurality of protrusions 12, and a conduction component is arranged between the pressure block 7 and the flow storage bin 4.

[0024] Specifically, Fig. 9 As shown, in the initial state of the flow guide assembly, the elastic rod 8 is located at the position c in the positioning groove 10. At this time, the sealing baffle 14 and the sealing groove 15 are in a tightly fitted state, which is used to block the flow storage bin 4. When the flow storage bin 4 at the specified position needs to be opened, the protrusion 12 is pressed to drive the pressure block 7 to move downward. At this time, the elastic rod 8 contacts the inclined surface at the position d and slides to the position e. Then the protrusion 12 is released, and the elastic rod 8 enters the lowest end of the positioning groove 10 along the inclined surface at the position e through the action of the spring 9. The spring 9 drives the pressure block 7 to move downward. When the pressure block 7 is lifted, the sealing baffle 14 is also lifted, thereby releasing the connection between the fluid storage bin 4 and the flow guide chamber 3; when the fluid storage bin 4 needs to be closed, the protrusion 12 is pressed again to drive the pressure block 7 to move downward. At this time, the elastic rod 8 contacts the inclined surface of the a position, and enters the b position along the inclined surface of the a position, and uses the inclined surface of the b position to reach the upper side of the c position. After the pressure block 7 is released, the spring 9 is used to tighten the elastic rod 8 to make it hang in the c position groove. Since the c position groove is inclined to the left, the elastic rod 8 is under the action of the spring 9 and is located below the d position.

[0025] like Fig.10 As shown, the conduction component includes a sealing baffle 14 fixedly connected to the side wall of the pressure block 7, the sealing baffle 14 is L-shaped, a through groove 13 is opened on the side wall of the flow storage bin 4, the sealing baffle 14 extends into the through groove 13, a sealing groove 15 is opened on the side wall of the through groove 13, the sealing baffle 14 is adapted to the sealing groove 15, and a drainage hole 16 is opened on the side wall of the pressure block 7.

[0026] Among them, a sealing ring can be installed on the side of the sealing baffle 14 according to actual needs. When the sealing baffle 14 is in a closed state, the sealing ring can fit between the sealing groove 15 to further improve the sealing effect. In addition, when the flow storage bin 4 is connected with the guide cavity 3, the drainage hole 16 corresponds to the position of the through groove 13, so that the cooling water can be quickly filled in the flow storage bin 4.

[0027] like Figure 6 As shown, the pressurizing assembly includes two expansion airbags 19 arranged in the inner cavity of the pillow body 1, one end of the two expansion airbags 19 is fixedly connected to a three-way pipe 20, one end of the three-way pipe 20 passes through the pillow body 1 and is fixedly connected to a pressing airbag 21, and a pressure relief valve 22 is installed on the side wall of the three-way pipe 20 near the pressing airbag 21.

[0028] Specifically, the principle between the expansion airbag 19 and the pressing airbag 21 can be referenced from the airbag sphygmomanometer. When it is necessary to fill the flow storage bin 4 with cold water, the pressing airbag 21 is continuously squeezed to inflate the expansion airbag 19. The expansion airbag 19 expands and squeezes the cold water in the pillow body 1, and the water flows into the diversion cavity 3. As the pressure increases, the cold water enters the corresponding flow storage bin 4 through the through groove 13, so as to achieve local temperature control. When the cold water needs to be discharged, the pressure relief valve 22 is opened to release the gas in the expansion airbag 19, and the internal space of the pillow body 1 increases. The cold water in the diversion cavity 3 flows back to the inner cavity of the pillow body 1, and when the pressure relief valve 22 is exhausted, a negative pressure is generated in the inner cavity of the pillow body 1. The negative pressure is used to open the one-way valve 18, and the cold water in the flow storage bin 4 flows back to the inner cavity of the pillow body 1 through the reflux hole 17, so as to facilitate adjustment when it is used next time.

[0029] like Figure 2 As shown, a plurality of reinforcing ribs 28 are fixedly connected between the upper and lower side walls of the inner cavity of the pillow body 1, and the reinforcing ribs 28 are made of elastic material. The reinforcing ribs 28 are made of rubber, silicone, plastic or metal elastic parts, etc., which increase the strength of the pillow body 1 while having good elasticity, increasing the comfort of the patient without discomfort.

[0030] Example 2: Figure 1 and Figure 6 As shown, based on Example 1, this embodiment specifically discloses a cooling method for cold water: Two temperature control pipes 23 are fixedly connected to the side wall of the pillow body 1 , and the two temperature control pipes 23 are respectively a discharge pipe and an inlet pipe.

[0031] Specifically, in actual application, if the ice pillow needs to continuously apply ice to a single or multiple patients, the temperature control tube 23 can be connected to an external micro-refrigeration device, and the discharge pipe and the discharge pipe can be connected to the input and output ends of the refrigeration device respectively. The cold water is cooled by the refrigeration device and then flows back to the inner cavity of the pillow body 1. When the pump on the refrigeration device draws in unrefrigerated water through the discharge pipe, the discharge pipe discharges the cooled water accordingly. Since a space is formed between the inner cavity of the pillow body 1, the guide cavity 3 and the flow storage bin 4, the cooled water can be discharged from the inner cavity of the pillow body 1 into the guide cavity 3, and then from the guide cavity 3 into the flow storage bin 4, and finally flows back through the reflux hole 17 to ensure continuous use of the low temperature.

[0032] Among them, the external micro-refrigeration equipment can use NS850W-DC24, which is mainly used in medical refrigeration equipment, medical cold compress machine, coffee refrigerator and other fields.

[0033] Example 3: Figure 4 and Figure 5 As shown, based on Examples 1-2, this embodiment specifically discloses another structure that can achieve low temperature control: The storage assembly includes storage grooves 24 opened on the left and right end surfaces of the soft layer 2 , and the left and right end surfaces of the soft layer 2 are respectively fixedly connected with shielding curtains 25 .

[0034] When the patient needs temporary cold compress, he can directly take an appropriate amount of ice cubes or gel from the freezer, wrap it in a plastic bag and place it in the storage slot 24, and then wrap it with a shielding curtain 25; in addition, the cold compress method belongs to the existing conventional technology, so it will not be described in detail in this solution.

[0035] The working principle of the present invention is as follows: first, a proper amount of cold water is injected into the inner cavity of the pillow body 1 through the temperature control tube 23, and the temperature control tube 23 is connected to an external pump and a refrigeration device for circulating cold water for refrigeration, and then the refrigeration of the designated position flow storage bin 4 is adjusted according to the part of the patient that needs cold compress. In the initial state, the sealing baffle 14 and the flow storage bin 4 are both in a closed state. When it is necessary to connect the flow storage bin 4 with the diversion cavity 3, the soft layer 2 is removed, and the convex block 12 at the corresponding position is pressed. The elasticity of the sealing gasket 5 is used to make the convex block 12 press down the pressing block 7. At the same time, the spring 9 is compressed, so that the elastic rod 8 slides from above the positioning block 11 to below the positioning block 11. The pressing block 7 and the sealing baffle 14 are driven to move upward by the force of the spring 9, thereby opening the connection between the flow storage bin 4 and the diversion cavity 3. Repeating the above steps can connect multiple designated flow storage bins 4. Then, continue to pinch and press the airbag 21 to inflate the expansion airbag 19. The expansion airbag 19 expands in the pillow body 1 and squeezes the cold water. The water flows into the diversion cavity 3. As the pressure increases, the cold water enters the corresponding flow storage bin 4 through the through groove 13, thereby achieving local temperature control of the pillow body 1 and achieving an efficient ice compress effect on the patient.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
