Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a foot sleeve for local cooling of feet. Background Art

[0002] Erythermalgia is a rare paroxysmal vasodilative disease with unknown etiology. Its main characteristics include paroxysmal skin temperature increase, flushing, swelling and intense burning pain in the distal extremities, mainly in the toes and soles of the feet. When the disease attacks, the patient has extremely painful feet and cannot bear weight on the instep. Usually, the sitting or lying position is adopted and cold compress is used to effectively relieve the symptoms.

[0003] At present, the existing cooling foot sleeves usually use a low-temperature cold compress pack to contact the instep for local cooling. However, there is also a risk of frostbite during long-term low-temperature contact. Therefore, in the prior art, the cold compress pack is usually manually separated from the instep for intermittent cold compress operation. However, the operation of manually taking and placing the cold compress pack in and out of the foot sleeve is relatively inconvenient, and in this operation mode, the cold compress pack has only two modes of contact and non-contact with the instep, and the refinement degree of the cold compress operation is weak. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a foot sleeve for local cooling of feet, so as to solve the technical problems of inconvenient use and insufficient functionality caused by the operation of taking and placing the cold compress pack in the prior art.

[0005] To solve the above technical problems, the utility model specifically provides the following technical solutions:

[0006] A foot sleeve for local cooling of feet, comprising a foot sleeve main body and a foot sleeve bottom surface arranged at the bottom of the foot sleeve main body. The inside of the foot sleeve bottom surface is hollowed out to form a cavity. At least one side of the cavity is provided with an opening, and a cooling pack is replaceably arranged in the cavity.

[0007] The lower bottom surface of the cavity extends towards one side to form a supporting edge. A long groove extending along the length direction of the foot sleeve bottom surface is opened on the supporting edge. At least two upright columns are installed in the long groove. At least two supporting pieces are slidably arranged on each upright column. One end of each of the two supporting pieces is connected to the upright column and can longitudinally move along the length direction of the upright column, and the other ends are respectively arranged on both sides of the cooling pack to clamp the cooling pack.

[0008] As a preferred scheme of the utility model, the upright columns are slidably installed in the long groove through sliding pieces, and the two upright columns linearly slide in the long groove to adjust the positions of the two groups of supporting pieces clamping the cooling pack.

[0009] As a preferred embodiment of the present utility model, the sliding piece is circularly arranged, and the upright column can also rotate around its own axis in the long groove through the sliding piece;

[0010] External threads are arranged on the outer surface of the upright column. The upright column is connected with an integral sleeve in a threaded engagement manner through the external threads. The ends of the two support pieces are both arranged on the integral sleeve, and the upright column drives the integral sleeve to longitudinally move on the upright column through axial rotation.

[0011] As a preferred embodiment of the present utility model, the outer wall of the integral sleeve is connected with an outer sleeve in a threaded engagement manner. A ring piece is rotatably installed on the outer wall of the outer sleeve. The ring piece can rotate circumferentially on the outer wall of the outer sleeve, and the ring piece is fixedly arranged at the end of one of the support pieces;

[0012] The outer sleeve drives one of the support pieces to approach or move away from the other support piece by rotating on the outer wall of the integral sleeve.

[0013] As a preferred embodiment of the present utility model, a rolling head is rotatably installed on the support piece, and the rolling head rotates on the support piece around a straight line perpendicular to the upright column.

[0014] The present utility model has the following beneficial effects compared with the prior art:

[0015] The present utility model drives the cooling pack to move up and down in the cavity by using components such as the upright column and the support piece. Not only can the separation and contact between the cooling pack and the instep be realized without repeatedly taking and placing the cooling pack, but also fine adjustment can be carried out, so that the distance between the cooling pack and the instep can be adjusted and controlled. Thus, the cold compress effect in the non-contact situation is controlled by the size of the distance between the cooling pack and the instep, making the refinement degree of the cold compress operation of the device higher.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 3 shown, the present utility model provides a foot sleeve for local cooling of the foot, including a foot sleeve main body 1 and a foot sleeve bottom surface 2 provided at the bottom of the foot sleeve main body 1. The foot sleeve main body 1 and the foot sleeve bottom surface 2 are connected to form a foot sleeve that can be enclosed and connected to the patient's foot. Openings can be provided on the foot sleeve main body 1 for ventilation. The inside of the foot sleeve bottom surface 2 is hollowed out to form a cavity 3. At least one side of the cavity 3 is provided with an opening, and a replaceable cooling pack 4 is provided in the cavity 3.

[0024] By placing the cooling pack 4 in the cavity 3 of the foot sleeve bottom surface 2, through the temperature release of the cooling pack 4 in the cavity 3, cold compress treatment is performed on the foot bottom surface located above the cavity 3. Among them, the surface where the foot sleeve main body 1 is connected to the foot sleeve bottom surface 2, that is, the top surface of the cavity 3, can be made of a material that is easy to transmit temperature. On the one hand, it is conducive to temperature transfer, and on the other hand, as an isolation layer, it can also avoid the risk of frostbite.

[0025] Further, the lower bottom surface of the cavity 3 extends to one side to form a supporting edge 5. A long groove 6 extending along the length direction of the foot sleeve bottom surface 2 is provided on the supporting edge 5. At least two columns 7 are installed in the long groove 6. At least two supporting pieces 8 are slidably arranged on each column 7. One end of the two supporting pieces 8 is connected to the column 7 and can longitudinally move along the length direction of the column 7, and the other ends are respectively arranged on both sides of the cooling pack 4 to clamp the cooling pack 4.

[0026] In this device, the cooling pack 4 is mainly clamped by the supporting pieces 8, and then by moving the position of the supporting pieces 8, the cooling pack 4 is driven to approach the top surface of the cavity 3 (i.e., the foot bottom surface) and move away from the top surface of the cavity 3 (i.e., the foot bottom surface) to achieve the temperature control effect.

[0027] Specifically, after the supporting piece 8 clamps the cooling pack 4, by sliding the position of the supporting piece 8 on the upright column 7, the cooling pack 4 can be driven to move.

[0028] Among them, the area of the supporting piece 8 can be selected according to the actual situation. Selecting a supporting piece 8 with a larger area can have a better bearing effect on the cooling pack 4.

[0029] When in specific use, the patient assumes a sitting or lying position so that the feet are raised off the bottom surface, and then the device is put on for cold compress treatment. By moving the supporting piece 8, the cooling pack 4 is brought into contact with the top surface of the cavity 3. At this time, the temperature transfer is the highest, and the cold compress degree on the feet is the highest. If it is felt that the temperature at the bottom of the feet is too low and there may be a risk of frostbite, the supporting piece 8 is moved to make the cooling pack 4 move away, so as to achieve the purpose of temperature control.

[0030] Furthermore, the upright column 7 is slidably installed in the long groove 6 through a sliding piece 9. The two upright columns 7 linearly slide in the long groove 6 to adjust the position where the two groups of supporting pieces 8 clamp the cooling pack 4.

[0031] When the patient has an attack of the disease, the burning position will occur locally, such as at the toes, local sole, etc. Therefore, in this device, the upright column 7 is arranged to be able to slide in the long groove 6. Thus, when the supporting piece 8 clamps the cooling pack 4 and at the same time the upright column 7 slides in the long groove 6, the supporting piece 8 can push the coolant in the cooling pack 4 to move, thereby forming a raised part between the two upright columns 7. As Figure 2 shown, at this time, the raised part of the cooling pack 4 can be used to specifically perform cold compress on the local burning position. Therefore, in addition to being able to achieve the purpose of temperature control by adjusting the distance from the instep, this device can also form a raised part by adjusting the position of the upright column 7 to perform cold compress on a specific local position.

[0032] Among them, a roller head 14 is rotatably installed on the supporting piece 8. The roller head 14 rotates on the supporting piece 8 around a straight line perpendicular to the upright column 7. When the supporting piece 8 moves, the roller head 14 on its main body part can roll on the cooling pack 4, thereby reducing the friction during movement.

[0033] Among them, as Figure 3 shown, for the operation of the axial movement of the supporting piece 8 in this device, this device is completed by rotating the upright column 7.

[0034] The sliding piece 9 is circularly arranged, and the upright column 7 can also rotate around its own axis in the long groove 6 through the sliding piece 9.

[0035] External threads 10 are arranged on the outer surface of the upright column 7. The upright column 7 is connected with an integral sleeve 11 in a threaded engagement manner through the external threads 10. The ends of the two supporting pieces 8 are both arranged on the integral sleeve 11. The upright column 7 drives the integral sleeve 11 to longitudinally move on the upright column 7 by axial rotation.

[0036] As shown Figure 3 In the figure, the outer wall of the integral sleeve 11 is connected to the outer sleeve 12 in a threaded engagement manner. A ring plate 13 is rotatably mounted on the outer wall of the outer sleeve 12. The ring plate 13 can rotate circumferentially on the outer wall of the outer sleeve 12. The ring plate 13 is fixedly arranged at the end of one of the support plates 8.

[0037] The outer sleeve 12 drives one of the support plates 8 to approach or move away from the other support plate 8 by rotating on the outer wall of the integral sleeve 11.

[0038] When it is necessary to move the cooling pack 4 to adjust the distance between it and the bottom surface of the foot, at this time, the integral sleeve 11 is fixed and the column 7 is rotated. Since the integral sleeve 11 and the column 7 are connected by threads, and the column 7 is limited in the long groove 6, the integral sleeve 11 will move up and down on the column 7, thereby driving the support plate 8 and the cooling pack 4 clamped by the support plate 8 to move up and down, achieving the purpose of adjusting the distance and controlling the temperature.

[0039] Furthermore, when it is necessary to adjust the upper support plate 8 to approach or move away from the lower support plate 8 to clamp or loosen the cooling pack 4, at this time, the integral sleeve 11 is stabilized, and by rotating the outer sleeve 12, the outer sleeve 12 can be moved up and down on the integral sleeve 11, thereby achieving the movement of the upper support plate 8 to achieve the purpose of clamping or loosening the cooling pack 4.

[0040] Moreover, since the upper support plate 8 is rotatably mounted on the outer sleeve 12 through the ring plate 13, when the outer sleeve 12 is rotated, the upper support plate 8 will not rotate with it, that is, the angle of the upper support plate 8 will not be changed.

[0041] In addition, a leg sleeve 15 is connected to the foot sleeve main body 1. Among them, the connection between the foot sleeve main body 1 and the leg sleeve 15 uses a detachable connection method, so that it is more practical during use, and the carrying, storage and use effects are better. There are various structures for the specific detachable connection method in the prior art.

[0042] For example, the leg sleeve 15 and the foot sleeve main body 1 are respectively connected by a zipper connection method, and a gasket is further arranged on the inner side of the connection position to prevent the hardware zipper from rubbing against the ankle to cause skin damage. Or the connection between the two is completed by using a mushroom snap connection method. Among them, the mushroom snap connection method can be preferably used. The reason is that when the mushroom snap connection method is used, a gel cooling pack can be synchronously arranged on the back of the mushroom snap, so that the connection part between the foot sleeve main body 1 and the foot sleeve can also achieve the effect of local cooling, so that there is no dead angle in the cooling range and the cooling wrap is higher.

[0043] The leg sleeve 15 is disposed around the lateral circumference of the patient's calf. A gel cooling pack is provided inside the leg sleeve 15. Among them, the leg sleeve 15 and the main body of the foot sleeve 1 are made of ice-sensing fabric. Both the cooling pack 4 and the gel cooling pack can be cryogenically treated by being placed in a low-temperature environment for cooling. After cryogenic treatment, the gel cooling pack in the leg sleeve can directly act around the patient's calf to perform cryogenic treatment on the burning sensation at this position. The upper port of the leg sleeve 15 is provided as an elastic opening for fixing on the patient's leg. Its main body is made of an elastic material that can be stretched and contracted to adjust the overall length of the leg sleeve 15, improve the adaptability of the device, and be used for matching different patients.

[0044] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
