Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-freezing ice foot cover for chemotherapy patients. Background Art

[0002] Clinically, ice foot sleeves are an auxiliary tool used in chemotherapy. Their main function is to reduce the side effects of chemotherapy drugs on patients. Specifically, ice foot sleeves reduce the temperature of the feet and reduce blood flow to the feet, thereby reducing the damage of chemotherapy drugs to the feet, thereby relieving pain and numbness in the patients' feet, thereby improving the patients' quality of life.

[0003] Although the current ice foot cover has the above advantages, the inventors found that the current ice foot cover still has some shortcomings during actual use, specifically:

[0004] When the patient wears the ice foot covers, the patient's feet are inserted into the ice foot covers, so that heat exchange occurs between the ice foot covers and the patient's feet, thereby cooling the feet. However, since the patient's feet usually directly contact the inner layer of the ice foot covers or contact the inner layer of the ice foot covers after putting on disposable foot covers, the ice foot covers and the patient's feet are continuously in a high-efficiency heat exchange state during the entire process of wearing the ice foot covers. If the patient continues to wear the ice foot covers for a long time, the patient's feet are easily frostbitten. Therefore, after the patient wears the ice foot covers for a period of time, the patient's feet are usually pulled out of the ice foot covers, and after the patient's feet have rested for a period of time, the patient's feet are put into the ice foot covers again. In this way, although the risk of frostbite of the patient's feet can be reduced, the frequency of wearing or taking off the ice foot covers will increase, thereby increasing the inconvenience of the patient when using the ice foot covers.

[0005] Therefore, how to reduce the risk of frostbite on patients' feet while improving the convenience of patients using ice foot covers is an urgent problem that needs to be solved. Utility Model Content

[0027] 1. In the scheme of the present application, an air bag is arranged on the isolation sleeve. After the patient wears the isolation sleeve on his foot, the air bag can correspond to the ankle and / or the instep and / or the sole and / or the heel and / or the toe. In this way, after the foot wearing the isolation sleeve is inserted into the ice foot sleeve body, an air bag is separated between the ice foot sleeve and the patient's foot. When the air bag is deflated, the gas in the air bag is less. At this time, the heat conduction performance of the deflated air bag is better. The energy of the ice foot sleeve body is easily conducted to the patient's foot through the deflated air bag and the isolation sleeve, thereby helping to reduce the temperature of the patient's foot. Since the thermal conductivity of gas is poorer than that of solid, when the air bag is inflated, an insulating cavity can be formed in the air bag, so that The energy of the ice foot cover body is not easily transmitted to the patient's feet through the inflated air bag, which can reduce the speed of cooling the patient's feet by the ice foot cover body, thereby reducing the probability of the patient's feet being frostbitten; in this way, by controlling the inflation device to expand or deflate the air bag, the cooling intensity of the patient's feet by the ice foot cover body is adjusted, so that the patient's feet are alternately placed in an environment with high cooling intensity and low cooling intensity. During the process, the patient's feet do not need to be pulled out of the ice foot cover body, and the patient does not need to frequently put on or take off the ice foot cover body. Therefore, while reducing the risk of frostbite on the patient's feet, it can also improve the convenience of the patient when using the ice foot cover;

[0028] 2. Furthermore, the five sub-airbags are each connected to an inflation device separately, so that when one of the sub-airbags is inflated or deflated, the other four sub-airbags will not be affected. In this way, the cooling degree of the foot can be adjusted by region, and different cooling degrees can be applied to different regions of the patient's foot, thereby improving the flexibility of cooling different regions of the patient's foot. For the region on the foot that is prone to pain or numbness, the airbag corresponding to the region can be deflated, and the airbags corresponding to other regions can be inflated, thereby achieving cooling of the region on the foot that is prone to pain or numbness, while further reducing the risk of frostbite of the patient's foot;

[0029] 3. Furthermore, by providing an unlocking member, a first matching member and a second matching member, and controlling the unlocking member so that the first matching member and the second matching member are in a matching state or the first matching member and the second matching member are released from a matching state, the piston rod is fixed relative to the cylinder body or the piston rod can move relative to the cylinder body along the length direction of the cylinder body, thereby facilitating the control of the movement of the piston rod relative to the cylinder body and facilitating the fixing of the position of the piston rod relative to the cylinder body, thereby improving the stability of the sub-airbag when maintaining its state while improving the inflation and deflation of the sub-airbag;

[0030] 4. Furthermore, when the unlocking member is in the initial state, the unlocking member is exposed from the end face of the plug handle. In this way, when the plug handle is pressed by hand to apply a thrust to the plug handle, the unlocking member can be pressed while applying a thrust to the plug handle, so that the unlocking member can move relative to the plug handle, thereby releasing the first mating member from the second mating member and allowing the piston rod to move relative to the cylinder body, thereby facilitating the inflation or deflating of the first airbag, and also facilitating locking the pump after the external force is removed to prevent the piston rod from moving relative to the cylinder body.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] Example 1: This example provides an anti-freeze foot cover for chemotherapy patients, see Figure 1-Figure 3 As shown, it comprises an ice foot cover body 1 and a spacer 2, wherein the ice foot cover body 1 is used to load ice cubes, and the spacer 2 is used to be worn on the patient's foot, and a receiving area is formed in the ice foot cover body 1, and the receiving area is used to receive the foot wearing the spacer 2;

[0042] The spacer sleeve 2 is provided with an airbag 3, and the airbag 3 is connected to an inflating device 4, and the inflating device 4 is used to control the inflation amount of the airbag 3 to make the airbag 3 expand or deflate;

[0043] The airbag 3 is used to correspond to the ankle and / or the instep and / or the sole and / or the heel and / or the toes.

[0044] In the present application, by arranging the airbag 3 on the isolation sleeve, after the patient wears the isolation sleeve 2 on the foot, the airbag 3 can correspond to the ankle and / or the instep and / or the sole and / or the heel and / or the toe. In this way, after the foot wearing the isolation sleeve 2 is inserted into the ice foot cover body 1, the airbag 3 is separated from the ice foot cover and the patient's foot. When the airbag 3 becomes deflated, the gas in the airbag 3 is less. At this time, the deflated airbag 3 has better thermal conductivity. The energy of the ice foot cover body 1 is easily conducted to the patient's foot through the deflated airbag 3 and the isolation sleeve 2, which is beneficial to reduce the temperature of the patient's foot. Since the thermal conductivity of gas is poorer than that of solid, when the airbag 3 is inflated, an insulating cavity can be formed in the airbag 3. , making it difficult for the energy of the ice foot cover body 1 to be transmitted to the patient's feet through the inflated air bag 3, and being able to reduce the speed at which the ice foot cover body 1 cools down the patient's feet, thereby reducing the chance of frostbite on the patient's feet; in this way, by controlling the inflation device 4 to make the air bag 3 expand or deflate, the cooling intensity of the ice foot cover body 1 on the patient's feet is adjusted, so that the patient's feet are alternately placed in an environment of high cooling intensity and low cooling intensity. During the process, the patient's feet do not need to be pulled out of the ice foot cover body 1, and the patient does not need to frequently put on or take off the ice foot cover body 1. Therefore, while reducing the risk of frostbite on the patient's feet, it can also improve the convenience of the patient when using the ice foot cover.

[0047] Furthermore, by providing a first spacer layer and a second spacer layer, the comfort of the patient wearing the spacer 2 can be improved after the patient's feet come into contact with the first spacer layer made of soft fabric. At the same time, the second spacer layer can prevent liquid from penetrating into the spacer 2 from outside the spacer 2, thereby avoiding water from entering the spacer 2, which is beneficial for the patient's feet to be in a dry environment, thereby further improving the patient's comfort.

[0048] As a preferred implementation manner, on the basis of the above-mentioned manner, further, the airbag 3 includes five sub-airbags 5, namely a first sub-airbag, a second sub-airbag, a third sub-airbag, a fourth sub-airbag and a fifth sub-airbag, wherein the first sub-airbag is used to correspond to the ankle, the second sub-airbag is used to correspond to the instep, the third sub-airbag is used to correspond to the sole, the fourth sub-airbag is used to correspond to the heel, and the fifth sub-airbag is used to correspond to the toes;

[0049] The five sub-airbags 5 are each individually connected to an inflator 4 .

[0050] Furthermore, the five sub-airbags 5 are each individually connected to an inflation device 4, so that when one of the sub-airbags 5 is inflated or deflated, the other four sub-airbags 5 will not be affected. In this way, the cooling degree of the foot can be adjusted by region, and each area of ​​the patient's foot can correspond to a different cooling degree, thereby improving the flexibility of cooling each area of ​​the patient's foot. For areas on the foot that are prone to pain or numbness, the airbag 3 corresponding to that area can be deflated, and the airbags 3 corresponding to other areas can be inflated, thereby achieving cooling of the areas on the foot that are prone to pain or numbness while further reducing the risk of frostbite of the patient's feet.

[0052] Furthermore, by providing an extractor 7 and an inflation tube 6, when the piston rod 9 is moved relative to the cylinder 8 along the length direction of the cylinder 8, the space for storing gas in the cylinder 8 changes. When the space for storing gas in the cylinder 8 gradually increases, the extractor 7 extracts the gas in the sub-airbag 5, causing the sub-airbag 5 to gradually deflate. When the space for storing gas in the cylinder 8 gradually decreases, the extractor 7 injects the gas in the cylinder 8 into the sub-airbag 5, causing the sub-airbag 5 to gradually inflate. In this way, by controlling the movement of the piston rod 9 relative to the cylinder 8, the convenience of adjusting the amount of gas in the sub-airbag 5 can be improved.

[0054] When the first mating piece 10 and the second mating piece 12 are in a mating state, the piston rod 9 is fixed relative to the cylinder body 8;

[0055] When the first mating piece 10 and the second mating piece 12 are released from the mating state, the piston rod 9 can move relative to the cylinder body 8 along the length direction of the cylinder body 8 .
