Description

Technical Field

[0001] This invention relates to the field of ice application, and more specifically to an ice application device. Background Technology

[0002] After oral surgery, ice packs should be applied to the injured area for the first day or two to reduce swelling, lower local temperature, inhibit local blood circulation, slow the spread of inflammation, and stop bleeding as soon as possible.

[0003] However, during the ice application process, it is generally necessary to wrap the ice cubes with a towel and hold them down with your hand to prevent the ice cubes from slipping. After the ice melts, it is necessary to repeatedly add water to make ice, especially in hot weather, when the frequency of adding water and ice is even higher, which is very troublesome, delays the time for the ice application to reduce swelling, and reduces the efficiency of the ice application. Summary of the Invention

[0004] The present invention aims to provide an ice pack device to improve the efficiency of ice pack application.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ice pack device, comprising a face mask and a refrigeration container capable of holding water. The face mask comprises a rigid outer shell, and a cooling bag is provided inside the outer shell. The upper and lower ends of the cooling bag are respectively connected to an inlet pipe and an outlet pipe connected to the refrigeration container. Valves are provided at the ends of the inlet pipe and the outlet pipe. The refrigeration container is provided with a temperature sensor, a cooler, and a water pump. The cooler and the temperature sensor are connected and control the temperature inside the refrigeration container at zero degrees. The water pump is connected to the inlet pipe.

[0006] The beneficial effects of this plan are:

[0007] 1. The cooler lowers the temperature of the water in the cooling container to zero degrees Celsius, and the water pump delivers the water to the cooling bag for ice application, thereby achieving ice application to the wound. When the ice water in the cooling bag heats up, the valve on the outlet pipe is opened, and the water in the cooling bag flows back into the cooling container. This is convenient and quick, eliminates the need for manual replacement of ice, and reduces replacement time, thus improving the efficiency of ice application.

[0008] 2. In existing technologies, water is typically frozen into ice blocks for application to wounds. However, since ice is solid and cannot flow, it must be replaced with new ice blocks after it melts, which is cumbersome. In this solution, the temperature of the cooling container is controlled at zero degrees Celsius. At this temperature, the container contains an ice-water mixture, preventing all the water from freezing. This allows the ice-water mixture to be pumped into the cooling bag at fixed intervals, replacing the warmed water in the bag. If the temperature is below zero degrees Celsius, the ice blocks will not be pumped into the mask at all, eliminating the risk of frostbite to the patient.

[0009] Further, the inside of the shell is divided into several ice compressing areas, and each ice compressing area is provided with a cooling bag, the cooling bag comprises a corrugated pipe, the corrugated pipe is provided with flexible cloth on the side close to the skin, and the corrugated pipe, the flexible cloth and the shell form a containing cavity.

[0010] Further, the shell is divided into four ice compressing areas, and two ice compressing areas are arranged on the left and right sides respectively, and the ice compressing areas cover the zygomatic arch to the mandible of the patient.

[0011] Further, the corrugated pipe comprises an inner pipe and an outer pipe, a cold air cavity is formed between the inner pipe and the outer pipe, the cold air cavity is provided with a sealing frame on the side close to the skin, the sealing frame is provided with a gas hole, the gas hole is communicated with the cold air cavity, and the cold air cavity is closed on the side away from the skin through the inside of the shell.

[0012] Further, the sealing frame is further provided with a plurality of protrusions on the side close to the skin.

[0013] Further, one end of the water inlet pipe is provided with a first branch pipe and a second branch pipe, the first branch pipe and the second branch pipe are arranged in the refrigeration container, the first branch pipe is communicated with the water pump, the second branch pipe is provided with a backwater valve, the other end of the water inlet pipe is detachably communicated with the cooling bag, the valve comprises a water inlet valve and a water outlet valve, and the water inlet valve and the water outlet valve are arranged on the side close to the cooling bag of the water inlet pipe and the water outlet pipe respectively.

[0014] The scheme has the following effects:

[0015] 1. In order to facilitate the patient to move, the water inlet pipe and the backflow pipe are usually arranged to be long, and the temperature of the ice water in the water inlet pipe will rise after staying for a long time, so that the ice compressing effect is lost, therefore, when the containing cavity is filled with ice water, the backflow valve is opened, the gas enters the water inlet pipe from the water pump, and the ice water flows back along the backflow valve, so that the low temperature loss is prevented.

[0016] 2. During ice compressing, part of the ice slag enters the containing cavity of the cooling bag together with the ice water, and when the ice slag is completely melted, the ice water begins to rise in temperature, at this time, the water outlet valve is opened, the water flows out, then the water pump is opened, the ice water first discharges the air in the water inlet pipe, the water outlet valve is closed, and the ice water is refilled in the containing cavity; the water inlet and water outlet are continuously carried out, so that the flexible cloth of the cooling bag is continuously inflated and retracted, so that the effect of continuously pressing the wound position is achieved, the initial wound position is tightly attached, and the healing is accelerated.

[0017] 3. The face mask is divided into a plurality of ice compressing areas, so that ice water is pumped in for ice compressing according to different wound positions, so that the ice compressing is more targeted, and the ice compressing effect is improved.

[0018] 4. When the ice water enters the containing cavity, the bellows extends, the air holes of the bellows inhale air, the air and the ice water exchange heat and thus the cold air is formed; when the containing cavity is drained, the bellows contracts, at this time, the new ice water has not entered the containing cavity, and there is a gap period for the ice compress. At this time, the cold air is blown out from the air holes, on the one hand, the cold air continuously compresses the wound position to make up the gap period of the ice compress, prevent the temperature of the wound position from rising, and avoid the patient from feeling pain again; on the other hand, the water molecules liquefied around the skin of the patient are blown away, and the water is prevented from accumulating on the surface of the skin of the patient for a long time to breed bacteria.

[0019] 5. When the containing cavity is drained, the flexible cloth is no longer inflated and begins to shrink, at this time, the effect of the anesthetic gradually disappears, the pressure between the mask and the skin of the patient gradually transfers from the flexible cloth to the protrusions of the sealing frame, after the ice water leaves the containing cavity, the skin of the patient begins to recover part of the perception, and can feel the position of the protrusions. Since the inside of the sealing frame is the ice compress area, the patient can clearly perceive the ice compress area through the protrusions, and can judge whether the ice compress area accurately covers the wound position, and then adjusts the fixing position of the mask to adjust the ice compress area; and after the new ice water refills the containing cavity, the pressure is transferred to the flexible cloth again, so the skin of the patient will not feel uncomfortable due to the long-term pressing of the protrusions.

The proportion in the figure is only for easy display, and the volume of the containing cavity 52 can be adjusted according to the actual situation.

[0035] The use method of the ice application device is as follows:

[0036] 1. The refrigeration device reduces the temperature of the water in the refrigeration container 3 to zero degrees, at which temperature the water in the refrigeration container 3 is a mixture of ice and water, thereby preventing the water from completely freezing, and the water pump 31 fixed time interval to deliver water to the cooling bag for ice application, thereby realizing ice application to the wound site, when the ice water in the cooling bag is warmed up, the valve on the water outlet pipe 12 is opened, and the water in the cooling bag flows back to the refrigeration container 3.

[0037] 2. In order to facilitate the patient's movement, the water inlet pipe 11 and the return pipe are usually arranged to be relatively long, and after the ice water stays in the water inlet pipe 11 for a long time, the temperature will rise and the ice application effect will be lost, therefore, when the containing cavity 52 is filled with ice water, the return valve is opened, the gas enters the water inlet pipe 11 from the water pump 31, and the ice water flows back along the return valve, thereby preventing the loss of low temperature.

[0038] 3. During ice application, part of the ice slurry enters the containing cavity 52 of the cooling bag together with the ice water, and when the ice slurry is completely melted, the ice water begins to warm up, at which time the water outlet valve 47 is opened to make the water flow out, and then the water pump 31 is opened, the ice water first discharges the air in the water inlet pipe 11, the water outlet valve 47 is closed, and the ice water is refilled into the containing cavity 52; in this way, the water is continuously filled and discharged, so that the flexible cloth 51 of the cooling bag is constantly inflated and retracted, thereby achieving the effect of constantly pressing the wound site, and the initial wound site is tightly attached to accelerate healing.

[0039] 4. The face mask is divided into a plurality of ice application areas 25, so as to pump in ice water for ice application according to different wound sites, thereby making the ice application more targeted and improving the ice application effect.

[0040] 5. As Figure 6As shown, when the ice water enters the containing cavity 52, the bellows 6 is elongated, the air holes 66 of the bellows 6 inhale air, the air and the ice water exchange heat and then the cold air is formed; as Figure 5 As shown, when the containing cavity 52 is drained, the bellows 6 is contracted, at this time, the new ice water has not entered the containing cavity 52, and there is a gap period of ice compress. At this time, the cold air is blown out from the air holes 66, on one hand, the cold air continuously compresses the wound position to make up the gap period of ice compress, prevent the temperature of the wound position from rising, and avoid the patient from feeling pain again; on the other hand, the water molecules liquefied around the patient's skin 7 are blown away, and the water is prevented from accumulating on the surface of the patient's skin 7 for a long time to breed bacteria.

[0041] 6. When the containing cavity 52 is drained, the flexible cloth 51 is no longer inflated and begins to shrink, at this time, the effect of the anesthetic gradually disappears, the pressure between the mask and the patient's skin 7 gradually transfers from the flexible cloth 51 to the protrusions 65 of the sealing frame 64, after the ice water leaves the containing cavity 52, the patient's skin 7 begins to recover part of the perception, and can feel the position of the protrusions 65. Since the inner side of the sealing frame 64 is the ice compress area 25, the patient can clearly perceive the ice compress area 25 through the protrusions 65, and can judge whether the ice compress area 25 accurately covers the wound position, and then adjusts the ice compress area 25 by adjusting the fixed position of the mask. After the new ice water fills the containing cavity 52 again, the pressure is transferred to the flexible cloth 51 again, so the patient's skin 7 will not feel uncomfortable due to the long-term pressing of the protrusions 65.
