Referring to fig. 1, an apparatus 10 for preventing skin frostbite in an embodiment can prevent skin from being frostbitten during a cryotherapy, and can better protect the skin around the cryoprobe, so as to reduce pain of a patient and reduce risk of an operation. Specifically, the skin frostbite prevention device 10 includes a skin frostbite prevention bag 100, a storage container 200, a medium introduction tube 300, a medium discharge tube 400, and a circulation pump 500.
Referring to fig. 2, the anti-skin frostbite bag 100 in an embodiment includes a bag body 110, a first connecting member 120 and a second connecting member 130, wherein the first connecting member 120 and the second connecting member 130 are disposed on the bag body 110, and an anti-freezing medium can be filled in the bag body 110. It should be noted that: the antifreeze medium may be water or steam or the like. The first connector 120 and the second connector 130 can be matched, so that the antifreezing medium can be distributed on the periphery of the cryoprobe, and the skin on the periphery of the cryoprobe can be better protected, so that the pain of a patient is reduced, and the risk of operation is reduced.
The bag 110 is formed with a pin notch 111, the first connector 120 is located at one side of the pin notch 111, the second connector 130 is located at the other side of the pin notch 111, and the second connector 130 is detachably matched with the first connector 120.

The pouch 110 may be generally flower-shaped and at least two protrusions may be distributed around the center of the pouch 110 like petals. Taking argon helium knife as an example, when the tumor diameter is larger than 5cm, at least two cryoprobes are required to be combined for treatment, and the design of the contact pin notch 111 is at least two, so that the situation that at least two cryoprobes are required for treatment can be well adapted. In the present embodiment, the number of the protruding portions is four, and the number of the pin notches 111 is also four, so that the four-probe treatment device can be adapted to the four-probe treatment, and also to the one, two or three-probe treatment device. Of course, in other embodiments, the number of the protruding portions and the number of the pin notches 111 can be flexibly adjusted according to practical situations.
Optionally, the protruding portion is axe-shaped. The shape of the axe portion of the axe-shaped finger axe is such that the portion of the axe near the axe blade has a wider width than the portion of the axe far from the axe blade. Because the protruding part is formed by separating the pin notch 111, the protruding part is in the shape of an axe, on one hand, the size of the middle part of the pin notch 111 can be relatively larger so as to accommodate the cryoprobe, and on the other hand, the sizes of the two ends of the pin notch 111 can be relatively smaller so as to have better anti-freezing effect. Of course, in other embodiments, the projections may take other shapes, such as angles, etc.
The number of the first connectors 120 may be at least two, the number of the second connectors 130 may be at least two, one side of one pin notch 111 is provided with at least one first connector 120, and the other side is provided with at least one second connector 130.

Of course, other elements may be selected for the first connecting member 120 and the second connecting member 130, so that the second connecting member 130 can be detachably engaged with the first connecting member 120. Optionally, the material of the first connecting member 120 may be a transparent material, and the material of the second connecting member 130 may also be a transparent material, so as to reduce the sight line obstruction. For example, in the present embodiment, the first connector 120 is a snap of a snap, the second connector 130 is a snap of a snap, and both the snap and the snap are made of a polyolefin material.
Further, an inlet (not shown) for introducing an antifreeze medium is provided in the bag 110. Or the bag 110 is provided with an inlet (not shown) for introducing the antifreeze, and the bag 110 is provided with an outlet (not shown) for discharging the antifreeze. The existence of the inlet can ensure that the anti-skin frostbite bag 100 is not required to be filled with an anti-freezing medium in the bag body 110 when not in use, so that the anti-skin frostbite bag 100 can be stored and transported conveniently; when the anti-skin frostbite bag 100 is needed, the anti-freezing medium is filled again, so that the anti-freezing bag is simple and convenient. The presence of the outlet may serve to facilitate the removal of the anti-freeze medium from within the pouch body 110 to facilitate better disposal of the used anti-skin-freeze pouch 100. The design that the inlet and the outlet exist simultaneously can realize the recycling of the antifreezing medium. It will be appreciated that the number and location of the inlets and outlets may be flexibly arranged to facilitate selection of the appropriate inlets and outlets depending on the orientation of the cryoprobe distribution and the patient's position.
Further, when the bag 110 is provided with an outlet, the inlet and the outlet are respectively located on two adjacent protrusions. During treatment, an antifreezing medium can be introduced through an inlet on one protruding part 160, and an antifreezing medium can be introduced through an outlet on the other protruding part 160 adjacent to the inserted protruding part 160, so that the antifreezing medium on the periphery of the cryoprobe between the two adjacent protruding parts 160 can be circulated in time, and the antifreezing effect is enhanced.
Further, the anti-skin frostbite bag 100 further includes a check valve (not shown) provided at the inlet. The existence of the one-way valve can prevent the antifreezing medium in the bag body 110 from flowing out of the bag body 110 through the inlet, so that the antifreezing medium in the bag body 110 is reduced and the antifreezing injury effect is reduced, and is beneficial to realizing the recycling of the antifreezing medium.
