Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and in particular to a wearable device for rewarming lower limbs. Background Art

[0002] After trauma such as lower limb fractures, patients often experience swelling of the affected limb and low skin temperature due to inflammatory reactions and poor venous return. Proper temperature regulation can help reduce inflammation, promote blood circulation, and improve venous return.

[0003] Post-anesthesia hypothermia is one of the common perioperative complications, especially in patients with general anesthesia and spinal anesthesia. Due to the inhibition of the temperature regulation center and peripheral vasodilation, patients often experience a drop in body temperature after surgery. Active warming measures can effectively prevent and manage postoperative hypothermia. Warming is one of the important measures to ensure the success of anesthesia surgery and reduce postoperative complications.

[0004] At present, the commonly used rewarming methods for patients with trauma, massive blood loss, limb / lower limb fractures, and hypothermia after anesthesia include electric rewarming blankets and warm air filled into the blankets. Although these methods are effective, they have some defects: electric rewarming blankets may cause local overheating, posing a risk of burns, and the electric heating elements may have a hidden danger of leakage; warming air blankets heat unevenly, and the air heating efficiency is low, making it difficult to maintain a constant temperature.

The wrapping belt 12 is bonded to the outer wall of the outer restraint sleeve 1 to quickly put the outer restraint sleeve 1 and the inner restraint sleeve 2 on the patient's legs.

[0043] Embodiment 4:

[0044] See also Figure 6-Figure 8 As shown, on the basis of the first, second and third embodiments, the present invention provides a technical solution: the massage device includes a regulating valve 22, the output end of the water pump 17 is fixedly connected to a delivery pipe 23, one end of the delivery pipe 23 is connected to the regulating valve 22, and a connecting pipe 24, a massage pipe 25 and a rubber airbag 26 are arranged in the outer constraint sleeve 1 and the inner constraint sleeve 2;

[0045] One end of the delivery pipe 23 is connected to the connecting pipe 24, the tail end and the head end of the massage pipe 25 are connected to the connecting pipe 24, and one end of the connecting pipe 24 is connected to the inner wall of the water tank 15;

[0046] A rubber airbag 26 is provided between the connecting tube 24 and the massage tube 25 , and the connecting tube 24 , the massage tube 25 and the rubber airbag 26 are interconnected.

[0047] The inner walls of the installation box 14 and the water tank 15 are both provided with a plug hole 27 , and the connecting pipe 24 at the rear end of the massage device passes through the plug hole 27 and is connected to the inner wall of the water tank 15 .

[0048] Among them, the connecting tube 24, the insulation tube 13, the massage tube 25, and the rubber airbag 26 are arranged in an S-shaped curve inside the outer constraint sleeve 1 and the inner constraint sleeve 2. The massage tube 25 and the rubber airbag 26 are arranged on one side of the insulation tube 13, and the massage tube 25 and the rubber airbag 26 are spaced apart from the insulation tube 13.

[0049] In this embodiment, when the water pump 17 is working, part of the pure water is pumped into the delivery pipe 23, and the delivery pipe 23 delivers the pure water to the connecting pipe 24 and the rubber airbag 26. The water flow is controlled by the regulating valve 22, and the rubber airbag 26 expands and contracts to produce a massage effect, prevent lower limb venous thrombosis, and perform compression massage on the lower limbs; the flow rate and speed of the water flow are controlled by the regulating valve 22, and the intensity and frequency of the massage can be adjusted. As the water continues to flow, the water in the rubber airbag 26 flows back to the water tank 15 through the connecting pipe 24, and the airbag contracts, completing a massage action.

[0050] The hot water in the insulation tube 13 circulates in the outer restraint sleeve 1 and the inner restraint sleeve 2 to generate heat, and the heat accumulates. The water pump 17 in this embodiment works to pump part of the pure water into the delivery pipe 23, which will not affect the rewarming of the lower limbs.

[0051] Working principle: When in use, the outer restraint sleeve 1 and the inner restraint sleeve 2 are sleeved on the patient's legs. The setting of the notch 4 facilitates the outer restraint sleeve 1 and the inner restraint sleeve 2 to be quickly sleeved on the patient's legs. By tightening the zipper 5, the outer restraint sleeve 1 and the inner restraint sleeve 2 are fixed to the patient's legs. The device is fixed by the elastic band 3 and the wrapping band 12 to ensure that the lower limbs fit closely with the device.

[0052] When the patient's lower limbs are fatter, an adjustment device is added, and an extension belt 11 is fixed to the cloth belt 1 7 and the cloth belt 2 8 through a hidden buckle 9. The extension belt 11 is provided with a hidden buckle 9, and the extension belt 11 can be superimposed through the hidden buckle 9 to adapt to fatter patients. Then, the cloth belt 1 7 and the cloth belt 2 8 are connected to the zipper 5 through the zipper teeth 10 on both sides, and the adjustment device is fixed to the outer restraint sleeve 1;

[0053] It is also possible to provide a wrapping belt 12 and utilize the bonding between the wrapping belt 12 and the outer wall of the outer restraint sleeve 1 to accommodate patients with different leg circumferences. By utilizing the bonding between the wrapping belt 12 and the outer wall of the outer restraint sleeve 1, the outer restraint sleeve 1 and the inner restraint sleeve 2 can be quickly put on the patient's legs.

[0054] Add pure water into the water tank 15. After fixing, start the water pump 17. The water pump 17 transports the pure water to the heat exchange structure 19 through the conversion pipe 18. In the heat exchange structure 19, the pure water is heated and then enters the insulation pipe 13 through the hot water delivery pipe 20. The insulation pipe 13 is arranged on the outer wall between the outer restraint sleeve 1 and the inner restraint sleeve 2 to form a hot water circulation channel for rewarming the lower limbs. After the hot water circulates in the insulation pipe 13, it flows back to the water tank 15 through the return pipe 21 to complete a circulation cycle.

[0055] When the water pump 17 is working, part of the pure water is pumped into the delivery pipe 23, and the delivery pipe 23 delivers the pure water to the connecting pipe 24 and the rubber airbag 26. The water flow is controlled by the regulating valve 22, and the rubber airbag 26 expands and contracts to produce a massage effect, prevent lower limb venous thrombosis, and perform compression massage on the lower limbs; the flow rate and speed of the water flow are controlled by the regulating valve 22, and the intensity and frequency of the massage can be adjusted. As the water continues to flow, the water in the rubber airbag 26 flows back to the water tank 15 through the connecting pipe 24, and the airbag contracts, completing a massage action.
