Description

Technical Field

[0001] This utility model relates to the field of medical products, and in particular to an electric inflatable anti-pressure sore and electric heating leg warmer for surgery. Background Technology

[0002] Body temperature is one of the most vital signs in the human body, and maintaining a stable body temperature is essential for ensuring metabolism and normal bodily functions. The core body temperature of a normal adult is typically between 36.5 and 37.5 degrees Celsius. During anesthesia and surgery, due to various factors, the core body temperature may drop below 36 degrees Celsius; this condition is known as intraoperative hypothermia. Unplanned intraoperative hypothermia refers to a harmful drop in body temperature (core temperature below 36 degrees Celsius) that occurs during surgery, excluding conscious or therapeutic temperature-lowering measures. This is a common but preventable surgical complication. Studies both domestically and internationally show that the incidence of unplanned intraoperative hypothermia ranges from 44.3% to 83.3%. Perioperative hypothermia can lead to a series of adverse consequences, including shivering, increased cardiovascular and infection risks, prolonged anesthesia recovery time, and coagulation disorders.

[0003] Intraoperatively acquired pressure injury (IAPI) refers to localized damage to the skin and underlying soft tissue at bony prominences or in areas of contact with medical equipment during surgery, caused by the continuous application of pressure, friction, and shear forces. IAPI can lead to complications, increase hospital stays, and even threaten life, imposing a severe medical and economic burden on patients, their families, and society.

[0004] Currently available leg warmers only provide basic warmth and cannot continuously keep patients warm during surgery to prevent body temperature drop during prolonged procedures. Furthermore, these leg warmers are not specifically designed to prevent pressure injuries that may occur when surgical patients maintain a fixed posture for extended periods, such as bedsores or other skin and tissue damage caused by prolonged pressure.

The volume of at least a portion of the inflation / deflation component 3 is variable to drive the distance between the heating layer 11 and the warming layer 12 to change.

[0026] In this invention, a leg sleeve body 1, a heating component 2, and an inflation / deflation component 3 are provided. The leg sleeve body 1 includes a heating layer 11 and a warming layer 12. The warming layer 12 is detachably fitted onto the heating layer 11. The heating component 2 is disposed on the heating layer 11 and is used to heat the space inside the heating layer 11. The inflation / deflation component 3 is detachably installed between the warming layer 12 and the heating layer 11. At least a portion of the volume of the inflation / deflation component 3 is variable to drive changes in the distance between the heating layer 11 and the warming layer 12. In use, the heating layer 11 and the warming layer 12 are sequentially fitted onto the patient's leg. The heating layer 11 heats the patient's leg, while the warming layer 12 retains heat and improves heating efficiency, effectively alleviating hypothermia. The variable volume of the inflation / deflation component 3, which drives changes in the distance between the heating layer 11 and the warming layer 12, effectively alleviates pressure injuries.

[0027] Specifically, the heating layer 11 is made of cotton fabric rolled into a sock-like shape, with both ends of the cotton fabric detachably connected by a zipper. The heating layer 11 comes into contact with the patient's skin; the cotton fabric is skin-friendly, reducing patient discomfort. When putting on or taking off the heating layer 11, the patient can open the zipper to unfold it. The purpose of the zipper is to facilitate the patient's putting on and taking off of the heating layer 11.

[0028] Specifically, a bladeless fan 111 is embedded in the heating layer 11 at the ankle position. The bladeless fan 111 is used to enable gas exchange between the heating layer 11 and the outside, so as to avoid an overly stuffy environment inside.

[0029] Specifically, the insulation layer 12 is made of a combination of double-layer fleece and breathable non-woven fabric, which has good heat preservation performance and can effectively slow down the heat loss of the heating layer 11.

[0030] Correspondingly, the two ends of the insulating layer 12 are detachably connected by zippers. The purpose of the zippers is to facilitate the patient's putting on and taking off of the insulating layer 12.

[0031] Furthermore, the insulation layer 12 is provided with an opening 121 at the corresponding position of the bladeless fan 111 to facilitate gas exchange between the interior of the heating layer 11 and the outside.

[0032] Furthermore, the leg sleeve body 1 also includes a fastening hook and loop fastener 13. The hook side 131 of the fastening hook and loop fastener 13 is fixed to the outer surface of the heating layer 11, and the fleece side 132 of the fastening hook and loop fastener 13 is fixed to the inner surface of the insulation layer 12 and corresponds to the hook side of the fastening hook and loop fastener 13.

[0034] Specifically, the inflation / deflation assembly 3 includes an inflation / depression bladder 31 and an air pump. The inflation / depression bladder 31 is disposed between the heating layer 11 and the insulation layer 12, and the air pump is connected to the inflation / depression bladder 31 through a pipe.

[0035] Furthermore, the inflatable decompression bladder 31 has a tubular structure and a pair of spherical structures, with the pair of spherical structures respectively connected to both ends of the tubular structure.

[0036] Furthermore, the inflatable decompression bladder 31 is made of natural polymer rubber, which has good elasticity.

[0037] Furthermore, the spherical structure is a sphere with a diameter of 6cm in the non-inflated state and a sphere with a diameter of 10cm in the fully inflated state.

[0038] To facilitate patient use of the surgical electric inflatable pressure ulcer prevention and heating leg warmer, the surgical electric inflatable pressure ulcer prevention and heating leg warmer also includes a control component 4, which is connected to the heating component 2 and the inflation / deflation component 3 to adjust the working status of the heating component 2 and the inflation / deflation component 3.

[0039] Furthermore, the control component 4 includes a controller 41, an operation panel 42, a temperature sensor 43, and a humidity sensor 44. The controller 41 is electrically connected to the operation panel 42, the temperature sensor 43, the humidity sensor 44, the air pump, the power supply unit, and the bladeless fan 111. The operation panel 42 is used to input commands to the controller 41. The temperature sensor 43 is fixed inside and on the heating layer 11 and is used to monitor the temperature. The humidity sensor 44 is fixed inside and on the heating layer 11 and is used to detect the humidity. The controller 41 receives the commands from the operation panel 42, the detection results from the temperature sensor 43, and the detection results from the humidity sensor 44, and generates control signals to drive the air pump, the power supply unit, and the bladeless fan 111 according to its internal preset program, and sends these signals to the air pump, the power supply unit, and the bladeless fan 111 respectively. It should be noted that the internal program of the controller 41 is a commercially available temperature and humidity feedback control program.

[0040] In use, first, the heating layer 11 is placed on the patient's leg, then the warming layer 12 is placed on the outside of the heating layer 11 and secured with the fastening Velcro 13. The inflatable decompression bladder 31 is placed between the heating layer 11 and the warming layer 12.
