[0002] During the surgical process, the surgical site of the patient needs to be exposed for disinfection operations. Usually, the operating room needs to maintain a low temperature condition of 22°C - 26°C. Long-term exposure of the patient's skin to a low-temperature environment is likely to cause a decrease in body temperature, affecting the patient's comfort and the surgical effect.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0033] During the patient's surgery, the environmental temperature in the operating room is usually maintained in a low-temperature laminar flow state of 22°C - 26°C to prevent bacterial growth. However, in the case of longer surgeries, especially surgeries for patients in the lithotomy position or the jackknife position, this surgical position affects the overall coverage of the lower limbs, and the leg rests of the operating table are relatively hard. The patient's lower limbs are exposed for a long time, and this low-temperature environment is likely to cause the patient to develop hypothermia. The patient's lower limbs are in a low-temperature state for a long time, which not only affects the patient's comfort but may also affect the surgical effect and postoperative recovery. Secondly, during the surgery, the patient remains in the same position for a long time, which may lead to poor blood return in the lower limbs, affecting blood circulation in the lower limb area and increasing the patient's risk of developing deep vein thrombosis (VTE).

[0034] Based on the above, the present application provides an inflatable leg sleeve that can effectively keep the lower limbs warm, and at the same time can promote blood circulation in the patient's lower limbs to a certain extent, reducing the patient's risk of developing deep vein thrombosis (VTE), thereby improving the comfort and safety of the patient during the surgery.

[0035] The following further details the inflatable leg sleeve provided by the present application in conjunction with the accompanying drawings and specific embodiments.

[0036] As Figures 1 to 5 shown, the inflatable leg sleeve disclosed in the present application includes: a body 10. The body 10 can be set in a conical tube shape and sleeved on the patient's lower limbs, or the body 10 can be set in an unfolded trapezoidal structure. After the second surface 12 is attached to the patient's lower limbs, the body 10 is then wrapped around the patient's lower limbs and fixed to the patient's lower limbs. After the inflatable cavity 13 is inflated, the pressure in the inflatable cavity 13 can be transmitted to the surface of the patient's lower limb skin, thereby giving a certain pressure stimulus to the patient's lower limbs. When the body 10 is set in an unfolded trapezoidal structure, the width range of the upper end of the body 10 is 50 - 80 cm, the width range of the lower end is 30 - 50 cm, and the length range is 100 - 140 cm. In practical applications, inflatable leg sleeves of different size models can be designed so that the inflatable leg sleeve can adapt to patients of most body types. Among them, the length direction of the body 10 is the same as the length direction of the patient's lower limbs, the upper end of the body 10 is close to the patient's thigh, and the lower end is close to the patient's calf.

[0037] Specifically, the body 10 includes a first surface 11 and a second surface 12 disposed away from each other in the thickness direction. Among them, the first surface 11 faces away from the patient's lower limbs, the second surface 12 is used to contact the patient's lower limbs, and a plurality of independent inflatable cavities 13 are provided between the first surface 11 and the second surface 12. Warmed gas can be filled into the inflatable cavities 13 to achieve the function of keeping the patient's lower limbs warm.

[0038] In the embodiment of the present application, a plurality of inflation nozzles 111 are provided on the first surface 11, and a plurality of air outlet holes 121 are provided on the second surface 12. Each inflation chamber 13 is communicated with one inflation nozzle 111 and at least one air outlet hole 121. The inflation nozzle 111 is used to connect an inflatable warming device. The plurality of inflation nozzles 111 are alternately opened to alternately fill the plurality of inflation chambers 13 with warming gas through the inflatable warming device. The air outlet hole 121 is used for the release of the gas in the inflation chamber 13.

[0039] The release of the gas in the inflation chamber 13.

[0040] Specifically, the number of the inflation nozzles 111 corresponds one-to-one to the number of the inflation chambers 13. One inflation nozzle 111 is provided for one inflation chamber 13. When the inflation nozzle 111 is connected to the inflatable warming device, warming gas can be filled into the inflation chamber 13. Since the plurality of inflation chambers 13 are independent of each other, the inflation nozzles 111 corresponding to the plurality of inflation chambers 13 can separately control the inflation process. For example, the plurality of inflation nozzles 111 can be respectively connected to a plurality of inflatable warming devices, and the intermittent inflation of the plurality of inflation chambers 13 can be controlled by controlling the intermittent opening of the plurality of inflatable warming devices; or, the plurality of inflation nozzles 111 can be simultaneously connected to the same inflatable warming device, but the opening of the plurality of inflation nozzles 111 is separately controlled to control the intermittent inflation of the plurality of inflation chambers 13.

[0041] It can be understood that for patients undergoing long-term surgery, through the intermittent inflation of the above-mentioned plurality of inflation chambers 13, the skin microcirculation of the lower limb compression part of the patient can be promoted, and the occurrence of pressure injury and deep vein thrombosis (VTE) can be reduced.

[0042] The air outlet hole 121 provided on the second surface 12 can be used for the release of the gas in the inflation chamber 13, so that the inflation chamber 13 is maintained within an appropriate pressure range. And when the gas in the inflation chamber 13 can flow to the outside of the leg sleeve through the air outlet hole 121, the warming gas in the inflation chamber 13 is in a circulating state, that is: while the warming gas is being introduced, the low-temperature gas in the inflation chamber 13 can flow out from the air outlet hole 121, so as to ensure that the gas in the inflation chamber 13 can be maintained at a certain temperature condition, and the warming effect on the lower limbs of the patient is ensured.

[0043] It should be noted that when the pressure in the inflation chamber 13 increases, the second surface 12 of the main body 10 closely adheres to the skin of the patient's lower limb. The air outlet holes 121 are blocked from discharging air, and the air pressure in the inflation chamber 13 continues to increase to exert a compressive effect on the patient's lower limb. When the inflation stops, the gas in the inflation chamber 13 slowly leaks out from the air outlet holes 121, and the pressure in the inflation chamber 13 decreases, and the patient's lower limb is relaxed. Thus, the alternation between compression and relaxation of the patient's lower limb is realized, promoting blood circulation in the lower limb and effectively reducing blood stasis. Since the multiple inflation chambers 13 are independent, the skin of the patient's lower limb corresponding to the multiple inflation chambers 13 can be alternately compressed and relaxed, further enhancing the effect of promoting blood microcirculation. Among them, the number and size of the air outlet holes 121 can be designed according to actual needs, and the present application does not make specific limitations in this regard. In addition, when the second surface 12 contacts the skin of the patient's lower limb, breathable and soft materials can be used to improve the comfort of the patient, make the skin less likely to form a humid environment, and reduce the risk of the patient developing pressure sores.

[0044] In practical applications, after the patient enters the operating room, the inflatable leg sleeve can be worn on the patient before the anesthesia operation is performed on the patient, and the tightness can be adjusted and the patient's comfort can be confirmed. After wearing it, the inflatable warming device can be turned on during the patient's body position placement and skin disinfection to continuously keep the patient's lower limb warm and reduce the risk of body temperature reduction caused by skin exposure; continuous warming is still given until the patient wakes up and is transferred to the bed when the surgical drapes are removed after the operation, and the entire warming process is uninterrupted.

[0045] It should be noted that the structure of the inflatable leg sleeve is simple and can be processed and made of disposable materials. It can be discarded after use without the need for cumbersome cleaning and disinfection work, saving labor and time costs. At the same time, the risk of cross-infection caused by improper cleaning can be reduced. It should be noted that in the material selection of the inflatable leg sleeve provided in the embodiments of the present application, environmental protection should be emphasized, and materials that are degradable or recyclable should be used as much as possible, which helps to reduce environmental pollution caused by waste and also conforms to the current concept of sustainable development.

[0046] Optionally, the multiple air outlet holes 121 are evenly spaced on the second surface 12.

[0047] In a specific application, the air outlet holes 121 are used for the release of the gas in the inflation chamber 13. When the distribution density of the air outlet holes 121 is relatively large, the air outlet efficiency is relatively high, and it is relatively difficult to keep the pressure value in the inflation chamber 13 at a relatively high level. Therefore, the distribution density of the air outlet holes 121 can be designed according to the pressure range requirements of the inflation chamber 13. It can be understood that when the multiple air outlet holes 121 are evenly spaced on the first surface 11, the air outlet on the second surface 12 is more uniform, so as to ensure that the pressure on the skin part of the patient's lower limb in contact with the second surface 12 is more uniform.

[0048] In addition, the distribution density of the air outlet holes 121 can also be designed to increase or decrease along the length direction, and the present application does not make specific limitations thereto.

[0049] Optionally, the inflation nozzle 111 protrudes outward from the first surface 11 in the thickness direction of the body. The inflation nozzle 111 is used to be sleeved on the air outlet of the inflatable warming device. An elastic band 112 is arranged along the circumference of the inflation nozzle 111, and a first fixing band 113 is also arranged on the outer side surface of the inflation nozzle.

[0050] Specifically, as Figure 6 shown, the inflation nozzle 111 protrudes outward from the first surface 11. The size of the inflation nozzle 111 is set to be adapted to the size of the air filling tube of the existing inflatable warming device. During use, the air filling tube can be sleeved on the inflation nozzle 111 to smoothly input the warming gas into the inflation cavity 13.

[0051] The inflation nozzle 111 and the body 10 are of an integrally formed structure and protrude outward from the first surface 11. Since the body 10 is made of a flexible material, the inflation nozzle 111 is also made of a flexible material. An annular clamping groove is usually arranged at the end of the air filling tube. It should be noted that the inflation nozzle 111 provided with the elastic band 112 can be similar to the structure of a sleeve. When the inflation nozzle 111 is connected to the air filling tube, it can be sleeved on the end of the air filling tube. The elastic band 112 arranged along the circumference of the inflation nozzle 111 can be embedded in the annular clamping groove of the air filling tube to prevent the air filling tube from falling off from the inflation nozzle 111 and strengthen the connection strength between the air filling tube and the inflation nozzle 111. As Figure 6 shown, in the embodiment of the present application, the number of the elastic bands 112 arranged along the circumference of the inflation nozzle 111 is two. The two elastic bands 112 are arranged at intervals along the axial direction of the inflation nozzle 111. The arrangement of the elastic bands 112 can further enhance the connection effect between the inflation nozzle and the air filling tube and ensure the reliability of the inflatable leg sleeve; the first fixing band 113 arranged on the outer side surface of the inflation nozzle 111 can be an adhesive tape. The number of the first fixing bands 113 can be two. The two first fixing bands 113 can be wound around the outside of the inflation nozzle 111. While strengthening the connection strength between the inflation nozzle 111 and the air filling tube, it can also be used to achieve the seal between the inflation nozzle 111 and the air filling tube and effectively prevent the warming gas from leaking out.

[0052] In an alternative embodiment of the present application, the body 10 further includes a heat preservation layer 14, and the heat preservation layer 14 is arranged between the first surface 11 and the inflation cavity 13.

[0053] Specifically, the heat preservation layer 14 can be a cotton sandwich layer. The cotton sandwich layer has a soft property and is filled with cotton or other heat preservation materials inside. The heat preservation layer 14 is arranged between the first surface 11 and the inflation cavity 13, which can effectively prevent the heat in the inflation cavity 13 from dissipating from the first surface 11, thereby improving the heat preservation effect provided by the inflatable leg sleeve to the patient.

[0054] In an alternative embodiment of the present application, the main body 10 further includes a waterproof layer 15, which is disposed between the first surface 11 and the thermal insulation layer 14, and / or between the thermal insulation layer 14 and the inflatable cavity 13.

[0055] In a specific application, the waterproof layer 15 can prevent the flushing liquid from wetting the patient's lower limbs during the operation, and at the same time, the flushing liquid is not easily introduced into the thermal insulation layer 14. The warm air can quickly dry the surrounding liquid to maintain the patient's body temperature.

[0056] Optionally, the inflatable leg sleeve further includes a first fixing portion 21 and a second fixing portion 22. The first fixing portion 21 and the second fixing portion 22 are respectively disposed on both sides of the main body 10 along the width direction. The main body 10 is adapted to be wound around the user's lower limbs, and the first fixing portion 21 and the second fixing portion 22 are detachably connected to fix the main body 10 to the user's lower limbs.

[0057] In the embodiment of the present application, the first fixing portion 21 is one of the fuzzy surface and the hook surface of the magic tape, and the second fixing portion 22 is the other of the fuzzy surface and the hook surface of the magic tape. Both sides of the main body 10 along the width direction are adhered by the magic tape to achieve the fixation of both sides. In practical applications, the second surface 12 can be first attached to the skin of the patient's lower limbs, and then the first fixing portion 21 and the second fixing portion 22 are fixed to complete the wearing of the inflatable leg sleeve.

[0058] Optionally, the inflatable leg sleeve further includes a third fixing portion 23 and a fourth fixing portion 24. The third fixing portion 23 and the fourth fixing portion 24 are respectively disposed on both sides of the main body 10 along the width direction. The third fixing portion 23 and the fourth fixing portion 24 are detachably connected to fix the main body 10 to the operating table. In practical applications, the settings of the third fixing portion 23 and the fourth fixing portion 24 can fix the patient's lower limbs to the leg support to prevent the patient from being accidentally injured due to the accidental detachment of the lower limbs.

[0059] In the embodiment of the present application, the third fixing portion 23 and the fourth fixing portion 24 are set as straps. After the leg sleeve is worn on the patient's leg, the patient's leg can be placed on the leg board or leg support of the operating table, and then the straps on the third fixing portion 23 and the fourth fixing portion 24 are tied to directly fix the leg sleeve and the patient's leg to the operating table to prevent the displacement of the patient's leg during the operation.

[0060] It should be noted that, in addition to the form of the straps, the third fixing portion 23 and the fourth fixing portion 24 can also be set as magic tapes, or a matching structure of snap fasteners and slots, as long as the fixation with the operating table can be achieved. The embodiment of the present application does not make specific limitations in this regard.

[0061] In the embodiment of the present application, the number of the third fixing parts 23 is multiple, and the multiple third fixing parts 23 are arranged at intervals along the length direction of the main body 10. The fourth fixing part 24 corresponds to the third fixing part 23 one by one.

[0062] It can be understood that when multiple third fixing parts 23 are provided, the number of the fourth fixing parts 24 is also multiple. The cooperation between the multiple third fixing parts 23 and the fourth fixing parts 24 fixes the inflatable leg sleeve, which can ensure the fixing strength between the inflatable leg sleeve and the leg frame of the operating table, and further improve the protection reliability for the lower limbs of the patient.

[0063] In summary, the inflatable leg sleeve provided by the embodiment of the present application has at least the following advantages:

[0064] In the embodiment of the present application, the main body of the inflatable leg sleeve is provided with a plurality of independent inflatable chambers, and each inflatable chamber is communicated with an inflatable nozzle. When the inflatable nozzle is connected to the inflatable heating device, gas can be filled into the inflatable chamber. When heated gas is filled, the temperature in the inflatable chamber rises, and the temperature in the inflatable chamber is transmitted to the second surface in contact with the user's lower limb, so as to play a role in keeping the user's lower limb warm. In addition, since the plurality of inflatable chambers are independent of each other, the inflation operations between the plurality of inflatable chambers can be independent of each other, so that intermittent inflation operations can be performed on the plurality of inflatable chambers respectively, realizing the alternating inflation between the plurality of inflatable chambers. The air outlet holes located on the second surface are used for the release of the gas in the inflatable chamber, so as to realize the gas circulation in the inflatable chamber. This intermittent inflation and deflation method enables the user's lower limb to switch between compression and relaxation, which can promote blood circulation in the lower limb and reduce blood stasis. The inflatable leg sleeve provided by the embodiment of the present application can simultaneously realize the functions of keeping warm and promoting blood circulation, effectively maintain the user's body temperature, and reduce the risks of pressure injury and venous thromboembolism.

[0065] The present application also discloses an inflation system, including an inflatable heating device, an inflation tube, and the inflatable leg sleeve as above. The two ends of the inflation tube are respectively connected to the inflatable heating device and the inflatable leg sleeve. The inflatable heating device intermittently introduces heated gas into the plurality of inflatable chambers 13 of the inflatable leg sleeve through the inflation tube.

[0066] Specifically, one end of the inflation tube is connected to the air outlet of the inflatable heating device, and the other end is connected to the inflatable nozzle 111 of the inflatable leg sleeve. The heated gas enters the inflatable chamber 13 from the inflatable heating device through the inflation tube. In practical applications, the gas temperature of the inflatable heating device can be adjusted to meet the warmth preservation requirements and microcirculation requirements of the patient's lower limbs.

[0067] Optionally, the inflation main pipe includes a first end and a second end disposed away from each other. The first end is provided with a second fixing band. The first end is connected to the inflatable warming device, and the second fixing band is fixed to the inflatable warming device. A plurality of inflation branch pipes are simultaneously connected to the second end of the inflation main pipe, and one inflation branch pipe is connected to one inflation nozzle.

[0068] Specifically, two second fixing bands can be provided. The lengths of the two second fixing bands can be respectively set to 20 cm. The inflation main pipe is connected to the air outlet of the inflatable warming device, and then the two second fixing bands can be wound around the outer wall of the inflation main pipe to ensure the connection reliability between the inflation main pipe and the inflatable warming device.

[0069] Exemplarily, in the embodiment of the present application, an inflatable leg sleeve includes two mutually independent inflation chambers 13. Each inflation chamber 13 is correspondingly provided with an inflation nozzle 111. The inflation pipe includes an inflation main pipe and two inflation branch pipes. The two inflation branch pipes are respectively connected to the two inflation nozzles 111. The inflation branch pipes can be clamped to block the flow of the warming gas between the inflation main pipe and the inflation chamber 13.
