Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vasospasm care equipment, and in particular to a heat preservation and moisture retention device for relieving vasospasm. Background Art
[0002] Vasospasm refers to a state in which blood vessels are in a contracted state due to certain factors. This state may lead to a decrease in local blood flow, causing pain and tissue ischemia. Vasospasm may occur in different parts of the body, such as coronary arteries, cerebral blood vessels, and peripheral blood vessels. The main symptoms of vasospasm include numbness, coldness, pain, and paleness at the ends of the fingers and toes. Vasospasm is common in the feet and hands of the limbs, usually caused by contact with cold water and cold air, and is more common in cold northern regions. Some studies believe that vasospasm is related to autonomic nervous system disorders. Since vasoconstriction and relaxation are mainly controlled by the autonomic nervous system, autonomic nervous system dysfunction may cause vasospasm.
[0003] The relationship between vasospasm and temperature and humidity is mainly reflected in the impact of changes in ambient temperature on blood vessels. A cold environment can cause vasoconstriction, thereby increasing the risk of vasospasm. Changes in humidity may indirectly affect vascular dilation and contraction by affecting body temperature regulation. In a cold or humid environment, the human body may reduce heat loss by contracting blood vessels, and this physiological response may aggravate the occurrence of vasospasm.
[0004] At present, in addition to drug treatment, some non-drug treatment methods can also be used to relieve vasospasm in the hands, such as hot compresses, cold compresses, appropriate stretching exercises and physical therapy. In hospitals, vasospasm is usually relieved by passing constant temperature and humidity gas into large gloves to provide a constant temperature and humidity environment for the hands. However, this treatment method may not be applicable to vasospasm in other parts of the body, such as the waist and abdomen. In addition, vasospasm is sudden, and the hand sizes of different patients are different, resulting in different difficulties in wearing gloves, which can easily affect the timeliness of treatment and affect the treatment effect.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0032] The invention is further described below by describing embodiments in conjunction with the accompanying drawings.
[0033] This embodiment provides a heat preservation and moisture retention device for relieving vasospasm, such as Figures 1 to 4As shown in , in order to solve the above technical problems, the technical solution adopted by the present invention is as follows: comprising a transparent thermal insulation layer 200, a plurality of transparent constant temperature and humidity layers 100 and a plurality of breathable areas 120. The plurality of constant temperature and humidity layers 100 are arranged on the thermal insulation layer 200 at intervals. In actual use, the plurality of transparent constant temperature and humidity layers 100 and the plurality of breathable areas 120 are located between the transparent thermal insulation layer 200 and the skin. Medical staff can directly observe the patient's skin through the transparent thermal insulation layer 200, the plurality of transparent constant temperature and humidity layers 100 and the plurality of breathable areas 120.
[0034] Several constant temperature and humidity layers 100 each have a first air cavity 110, and the first air cavity 110 is used to pass constant temperature and humidity gas. The constant temperature and humidity layer 100 has opposite contact surfaces and mounting surfaces, and several contact surfaces are arranged toward the patient; several air permeable areas 120 are arranged corresponding to the contact surfaces, and the air permeable areas 120 include several through holes 121, and each through hole 121 is connected to the first air cavity 110. In actual use, the first air cavity 110 is connected with a gas nozzle, and the positive pressure constant temperature and humidity gas enters the first air cavity 110 through the gas nozzle and then sprays out through several through holes 121 connected to the first air cavity 110. Since the contact surface is arranged toward the patient, the constant temperature and humidity gas sprayed from several through holes 121 can replace the gas around the patient's skin, so that the patient's skin is in a constant temperature and humidity environment. Specifically, the temperature and humidity of the constant temperature and humidity gas can be adjusted according to actual needs to provide a better vasospasm relief effect.
[0035] Several mounting surfaces are arranged at intervals on the insulation layer 200, and the insulation layer 200 is used to reduce the heat loss of the constant temperature and humidity gas in the first air cavity 110. When the patient is ill, the temperature required to relieve vasospasm generally has a large temperature difference with the ambient temperature. When the constant temperature and humidity layer 100 is directly exposed to the air, the constant temperature and humidity gas in the first air cavity 110 is easy to exchange heat with the air, which affects the temperature of the constant temperature and humidity gas, reduces the treatment effect, and also increases the energy consumption when preparing the constant temperature and humidity gas.
[0036] In one embodiment, Figure 1 , Figure 2 As shown in , the heat preservation and moisture retention device also includes: a connecting belt 300, which is arranged on the heat preservation layer 200, and the heat preservation layer 200 and the connecting belt 300 form a first annular structure and are used to be sleeved on the patient's limbs or waist and abdomen.
[0037] Preferably, two connecting belts 300 are provided, and the two connecting belts 300 are respectively provided at opposite ends of the thermal insulation layer 200, wherein both sides of one of the connecting belts 300 are first connecting surfaces (such as the fur surface in Velcro, which is not easy to irritate the patient's skin when in contact with the patient), and the other connecting belt 300 is also provided with a second connecting surface (such as the hook surface in Velcro, which can be connected to the fur surface) on the surface facing the patient.
[0038] During actual use, when it is necessary to use it on the patient's waist and abdomen, the second connecting surface (hook surface) can be connected to the first connecting surface (fur surface) facing away from the patient, so that the thermal insulation layer 200 and the connecting belt 300 form a first annular structure and are sleeved on the patient's waist and abdomen; when it is necessary to use it on the patient's limbs, the second connecting surface (hook surface) can be connected to the first connecting surface (fur surface) close to the patient, so that the thermal insulation layer 200 is folded in half, and several constant temperature and humidity layers 100 (preferably two) located in the thermal insulation layer 200 clamp the patient's limbs, thereby reducing the distance between the several constant temperature and humidity layers 100 and the skin of the patient's limbs.
[0039] In one embodiment, Figure 1 , 2 As shown in the figure, a plurality of constant temperature and humidity layers 100 are arranged on the insulation layer 200 at intervals along the circumference of the first annular structure, and each contact surface is arranged toward the axis of the first annular structure, and the plurality of constant temperature and humidity layers 100 are detachably connected to the insulation layer 200.
[0040] Preferably, the constant temperature and humidity layer 100 has various sizes and thicknesses, and constant temperature and humidity layers 100 of the same or different specifications can be selected and installed on the thermal insulation layer 200 for use as needed. Several constant temperature and humidity layers 100 are preferably connected to the thermal insulation layer 200 by Velcro, and the thermal insulation layer 200 is preferably provided with a fur surface of the Velcro, which covers the surface of the thermal insulation layer 200 facing the patient.
[0041] In one embodiment, Figures 1 to 4 As shown in , the heat-insulating layer 200 includes: a transparent shell 210 , the shell 210 has a second air cavity 220 therein, and the second air cavity 220 is filled with gas.
[0042] It is understandable that transparent heat-insulating materials are less available and may be more expensive, while materials such as vacuum glass are relatively hard and not easy to bend, and the thermal conductivity of gas is relatively poor. By filling the second air cavity 220 with gas, the gas in the second air cavity 220 does not produce convection with the gas in the first air cavity 110 and the air, thereby achieving better heat-insulating effect while achieving bendability and transparency.
[0043] In one embodiment, Figure 2 , Figure 3 , Figure 4As shown in , a plurality of second air cavities 220 are provided, and the plurality of second air cavities 220 are spaced apart along the radial direction of the first annular structure, and each second air cavity 220 is separated.
[0044] Specifically, since the plurality of second air cavities 220 are separated from each other, the gas in the plurality of second air cavities 220 will not generate convection. Moreover, the temperature difference between each adjacent second air cavities 220 will tend to be close, so the heat or cold loss through heat exchange will be greatly reduced, and the thermal insulation performance of the thermal insulation layer 200 will be greatly enhanced.
[0045] Carbon dioxide is filled in the plurality of second air cavities 220. It is understandable that the heat transfer efficiency of carbon dioxide is high, which can well enhance the heat insulation performance of the thermal insulation layer 200.
[0046] In one embodiment, Figures 1 to 4 As shown in the figure, the heat preservation and moisturizing device also includes: a plurality of air-blocking rings 400, the plurality of air-blocking rings 400 are arranged on the corresponding contact surfaces, and the breathable area 120 is located in the corresponding air-blocking rings 400, and a constant temperature and humidity cavity is formed between the air-blocking rings 400, the contact surfaces and the patient's skin, and the air-blocking rings 400 are used to separate the constant temperature and humidity cavity from the outside world.
[0047] In one embodiment, Figures 1 to 4 As shown in , the air blocking ring 400 includes: a plurality of partitions 410 and a plurality of deformable portions 420. Preferably, the plurality of partitions 410 and the plurality of deformable portions 420 can be made of materials such as silicone, which are easily deformed when subjected to force to better fit the curve of the patient's skin.
[0048] Several partitions 410 are arranged along the edge of the contact surface, and the partitions 410 are used to separate the constant temperature and humidity chamber from the outside. Several deformation parts 420 are respectively arranged between two adjacent partitions 410, and the deformation parts 420 include several elastic parts 421 arranged along the edge of the contact surface and close to each other.
[0049] A plurality of partitions 410 and a plurality of deformable portions 420 form a second annular structure, and the deformable portion 420 is used to be compressed to reduce the axial length of the second annular structure to adapt to the skin curve of the patient.
[0050] Specifically, when the patient's limbs need to be treated, the limbs can be pressed against the deformation part 420. Compared with the partition part 410, the deformation range of each part of the deformation part 420 is larger, which can better separate the constant temperature and humidity chamber from the outside world. The partition part 410 is not squeezed by the limbs, so its deformation range changes less, and there is no need to increase its deformation range by setting multiple elastic parts 421. And because there are fewer gaps between the multiple elastic parts 421, it can better separate the constant temperature and humidity chamber from the outside world.
[0051] In one embodiment, Figure 4 As shown in , two partitions 410 are provided, the partitions 410 are arranged parallel to each other, and the two partitions 410 are arranged at both ends of the contact surface in the axial direction of the first annular structure;
[0052] The deformation portion 420 further includes a magnetic attraction portion 422 , which is disposed at one end of the elastic portion 421 away from the contact surface. The magnetic attraction portions 422 of two different air blocking rings 400 attract each other.
[0053] In actual use, when treating a limb through two constant temperature and humidity layers 100, the air blocking rings 400 on the two constant temperature and humidity layers 100 may deviate due to deformation of the constant temperature and humidity layers 100, resulting in a large gap between the air blocking rings 400 on the two constant temperature and humidity layers 100. The two air blocking rings 400 can be attracted to each other by the magnetic attraction portion 422, thereby reducing the gap between the air blocking rings 400 on the two constant temperature and humidity layers 100.
[0054] In one embodiment, Figures 1 to 4 As shown in , the heat preservation and moisturizing device further includes: a plurality of transparent support layers 500, which are arranged on the corresponding contact surfaces, and the support layers 500 are used to prevent the patient's skin from blocking the through hole 121. By increasing the distance between the contact surface and the patient's skin through the support layer 500, the constant temperature and humidity gas ejected from the through hole 121 can be more evenly covered around the patient's skin, achieving a better treatment effect.
[0055] In one embodiment, Figures 1 to 4 As shown in , the support layer 500 includes: a plurality of transparent vertical rods 510, the plurality of vertical rods 510 are evenly distributed on the contact surface, and the plurality of vertical rods 510 are non-parallel to the contact surface;
[0056] A plurality of transparent cross bars 520 are respectively connected to ends of the plurality of vertical bars 510 that are away from the contact surface, and the plurality of cross bars 520 are parallel to the contact surface.
[0057] In summary, the present application relates to the technical field of vasospasm nursing equipment, and discloses a heat preservation and moisture retention device for relieving vasospasm, which includes a transparent heat preservation layer, a plurality of constant temperature and humidity layers, and a plurality of breathable areas, each of the plurality of constant temperature and humidity layers has a first air cavity, the constant temperature and humidity layer has a contact surface and a mounting surface, the breathable area is arranged on the contact surface, the breathable area includes a plurality of through holes that are all connected to the first air cavity, and a plurality of mounting surfaces are arranged on the heat preservation layer at intervals. The present application arranges a plurality of constant temperature and humidity layers on the heat preservation layer, and after the contact surface of the constant temperature and humidity layer is facing the patient, constant temperature and humidity gas is introduced into the first air cavity, and the constant temperature and humidity gas is evenly moved to the patient's skin through the breathable area to provide a constant temperature and humidity environment for the skin, thereby relieving vasospasm; and the plurality of contact surfaces can be bent along with the skin of different parts of the patient, and are suitable for quickly providing constant temperature and humidity gas to various parts.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
