AI Technical Summary
In existing cardiovascular interventional wound compression devices, the plastic straps adhere tightly to the skin and are not permeable to moisture, resulting in a high-humidity environment that can cause skin redness, itching, and maceration dermatitis.
The plastic restraint strap has multiple first and second support sections on its inner side. The support sections are equipped with cooling filling chambers and air outlets. Combined with coolant and cold air flow, heat and moisture are dissipated, reducing skin humidity and discomfort caused by pressure.
The design of the gap between the support and the skin reduces the risk of sweating and skin maceration, reduces bleeding and exudation, shortens the hemostasis time, reduces postoperative bruising and edema, provides rapid analgesia, and improves skin comfort.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of medical devices, and more particularly, to a cardiovascular postoperative wound compression structure. BACKGROUND
[0002] Cardiovascular intervention is a technique that, through a minimally invasive channel in the skin, instruments such as catheters and guide wires are used to enter the vascular lumen, and under the guidance of images (X-ray, ultrasound, CT, intravascular ultrasound, etc.), the diseased part of the cardiovascular system is diagnosed and treated. After the intervention is completed, a wound compression structure is needed to compress the intervention wound site locally to prevent blood leakage and thrombus formation, reduce the risk of postoperative bleeding, promote wound healing, and reduce the incidence of postoperative complications.
[0003] Cardiovascular intervention is generally performed from the radial artery. The current compression method for the wound of the radial artery includes spiral nut compression or inflatable balloon compression. The spiral nut is often used with a simple magic tape or elastic band. There is no additional locking groove or anti-skid texture between the band and the base. Once the load direction changes (such as wrist rotation), the entire assembly will slip along the band gap, and under the compression of the single-point nut, the pressure is concentrated at the contact between the nut and the pressure plate, and there is no compression in other areas. The entire device is more likely to "lift" or slide on the convex and concave surface of the wrist. After the balloon is inflated, it can uniformly fit the contour of the wrist, the pressure distribution is smoother, the local shear force is reduced, and the friction between the balloon made of plastic material and the skin is more uniform and greater. Therefore, the current wound compression is generally performed by using the inflatable balloon compression method.
[0004] Although the inflatable balloon can avoid sliding and provide stable compression on the wound, the balloon compressor is closely attached to the skin (the plastic restraint band is closely attached to the skin surface), and almost no water vapor is allowed to pass through. Within a few hours after the operation, a high-humidity environment is formed between the skin and the band, which causes local skin redness, itching, and even maceration dermatitis or blisters in severe cases.

[0049] In the above scheme, the plurality of first support portions 3 and the plurality of second support portions 11 are arranged on the inner side wall of the plastic binding belt 1, the plurality of first support portions 3 bear the main load, the gap height between the plastic binding belt 1 and the skin is maintained, the plurality of second support portions 11 are in close contact with the skin, and certain point-shaped pressure buffering is provided, so that there is a certain gap between the plastic binding belt 1 and the skin, the water vapor and heat released by the skin have an outlet, the risk of sweat and skin immersion is reduced, and a high-humidity environment is avoided between the skin and the binding belt.
[0050] It should be noted that the compression air bag 2 can be integrally formed on the plastic binding belt 1, and the present embodiment is not limited in this regard.
[0051] As shown in Figure 2 ,Figures 4 to 6 As shown, in one embodiment provided by the present application, a cooling filling cavity 35 for storing liquid solidification is formed in the first support part 3, and cooling liquid is encapsulated in the cooling filling cavity 35 for cooling. The first support part 3 is further wrapped with a moisture-absorbing outer sleeve 33 for contacting the skin.
[0052] In one embodiment provided by the present application, the first support part 3 is in the shape of a cuboid, and a cavity is formed in the first support part 3; the first support part 3 comprises a pair of first side sealing plates 36, two second side sealing plates 38 respectively and perpendicularly fixed between the edges of the pair of first side sealing plates 36, and two metal sealing sheets 37 respectively fixed at the two ends of the two first side sealing plates 36 and the two second side sealing plates 38; a reinforcing framework 34 is arranged on the inner wall of the metal sealing sheet 37, and the two ends of the reinforcing framework 34 are respectively fixed with the two first side sealing plates 36.
[0053] By arranging the cooling filling cavity 35 in the first support part 3, and using the two first side sealing plates 36, the two metal sealing sheets 37, and the two second side sealing plates 38 to close the cooling filling cavity 35, the cooling liquid is encapsulated in the cooling filling cavity 35, and after being frozen, the cooling liquid can pass through the metal sealing sheet 37 and the moisture-absorbing outer sleeve 33 to contact the skin, and through heat conduction, the heat of the surface skin and superficial tissue is rapidly taken away, the skin sweating is reduced, the cold stimulation can cause the reflexive contraction of the local arteriole and capillary, and the blood flow is immediately reduced, thereby further reducing the bleeding and exudation on the basis of the compression of the radial artery, shortening the hemostasis time, significantly reducing the area and thickness of the bruise after the operation, and also reducing the tissue metabolic rate and capillary permeability, inhibiting the release of inflammatory mediators of vascular endothelial cells, thereby reducing the local edema after the operation, the cold feeling inhibits the conduction speed of the pain sensory nerve fiber through the "gate control theory", and at the same time, promotes the release of endogenous opioid peptides, providing a rapid analgesic effect, and the ice compress can reduce the burning and stinging sensation caused by over-tightness or long-term compression during the compression process.
[0054] In one embodiment provided by the present application, the two ends of the groove 12 on the plastic binding belt 1 are fixed with third magic tapes 31, and the two ends of the moisture-absorbing outer sleeve 33 are fixed with fourth magic tapes 32 capable of being bonded with the third magic tapes 31. Through this structure, the moisture-absorbing outer sleeve 33 and the rigid support part 3 are quickly fixed.
[0055] By adopting the above technical solution, before the plastic strap 1 is tied to the arm, the fourth Velcro 32 is separated from the third Velcro 31, the first support part 3 of the multiple rigid support parts is separated from the plastic strap 1, and the first support part 3 of the support assembly (the first side sealing plate 36, the second side sealing plate 38, and the reinforcement frame 34 can all be made of lightweight plastic material, such as PP GF30, ABS and other materials, the metal sealing sheet 37 is made of a metal sheet with high thermal conductivity, such as aluminum alloy. The reinforcing skeleton 34 inside the cooling filling cavity 35 can position the metal sheet to prevent the metal sheet from deforming, and at the same time provide a stable support for the entire support component first support part 3) The external moisture-absorbing outer sleeve 33 (the material can be made of ultra-fine microfiber flannel, which is mainly used to quickly absorb the condensed water droplets on the surface of the support component first support part 3 without excessive heat insulation and weakening the ice compress effect, and at the same time avoid indirect contact between the metal sealing sheet 37 and the skin) is peeled off from the outside of the support component first support part 3, and the support component first support part 3 is placed in the freezer in advance for freezing. After the operation is completed, the support component first support part 3 is taken out of the freezer, and the moisture-absorbing outer sleeve 33 is sleeved on the outside of the support component first support part 3, and then the rigid support part first support 3 is fastened through Velcro (the third Velcro 31 and the fourth Velcro Velcro 32) is bonded to the plastic restraint 1, and one of the metal sealing sheets 37 of the first supporting part 3 of the supporting assembly is in indirect contact with the surface skin through the moisture-absorbing outer sleeve 33. The liquid solid (ice cube) encapsulated in the cooling filling cavity 35 can quickly take away the heat of the surface skin and superficial tissue through heat conduction, reducing skin sweating. The cold stimulation will cause the reflex contraction of local arterioles and capillaries, immediately reducing the blood flow, thereby further reducing bleeding and exudation on the basis of radial artery compression, shortening the hemostasis time, and significantly reducing the area and thickness of postoperative bruises. It can also reduce tissue metabolic rate and capillary permeability, inhibit the release of inflammatory mediators of vascular endothelial cells, thereby reducing local edema after surgery. The cold sensation inhibits the conduction velocity of pain nerve fibers through the "gate control theory", and at the same time promotes the release of endogenous opioid peptides, providing a rapid analgesic effect. Ice compress can relieve the burning and tingling caused by excessive tightness or long-term pressure during compression.
[0056] like Figure 2 、 Figures 7 to 9 As shown, in one embodiment provided by the present invention, a flow channel is opened inside the plastic restraint belt 1, and a plurality of air outlets 5 connected to the flow channel are opened on the inner side of the plastic restraint belt 1, and a second air port 6 connected to the flow channel is fixedly connected to the plastic restraint belt 1, and a cold air flow is sent into the flow channel through the second air port 6.
[0057] By setting multiple air outlets 5, when the cold air flow is input to the flow channel in the plastic restraint belt 1 through the second air port 6, the cold air flow can be discharged from the air outlet 5 and blown on the skin, and the skin can be cooled by the cold air flow, and the skin can be cooled and analgesic treatment at any time according to the needs, reduce skin sweating and reduce humidity, improve the comfort of the skin.
[0058] As shown in Figure 2 and Figure 3 In an embodiment provided by the present application, the plurality of air outlets 5 are inclined and arranged on the plastic restraint belt 1, and the air outlet end of the air outlet 5 faces the anti-skid part 13. The cold air flow can be discharged from the air outlet 5 and blown on the anti-skid part 13, and the anti-skid part 13 can also be cooled to have the effect of heat conduction cooling on the skin.
[0059] In an embodiment provided by the present application, the inner wall of the plastic restraint belt 1 and the inner wall of the groove 12 are bonded with a heat-conducting film sheet 4, and the anti-skid part 13 is bonded on the heat-conducting film sheet 4. The heat-conducting film sheet 4 is used for heat conduction between the anti-skid part 13 and the first support part 3, and the plurality of anti-skid parts 13 are made of heat-conducting elastomer material. The anti-skid part 13 conducts heat from the skin to the heat-conducting film sheet 4 through contact with the skin to complete heat dissipation of the skin.
[0060] By adopting the above technical scheme, since the air outlet 5 is inclined, the cold air flow discharged from the air outlet 5 can not only be blown on the skin surface, but also be blown on the anti-skid part 13. The anti-skid part 13 is made of heat-conducting elastomer material (rubber base with high-thermal-conductivity filler, such as silicone base + boron nitride (BN) filler, which has corresponding application in electronic device heat dissipation pad and LED heat dissipation gasket). When the cold air flow is blown on the anti-skid part 13, the anti-skid part 13 can be cooled, so that the skin in contact with the anti-skid part 13 can be kept cool, and the heat of the anti-skid part 13 can also be conducted to the heat-conducting film sheet 4 (which can be made of flexible graphene film material or other flexible heat-conducting material, which is a mature existing technology, and will not be described here) on one side of the plastic restraint belt 1, to achieve better heat conduction and heat dissipation effect.
[0061] In an embodiment provided by the present application, the supply gas part 7 for supplying cold air flow to the second air port 6 is also included; the supply gas part 7 includes a shell 71, a metal pipe 74 fixed inside the shell 71, and a semiconductor refrigeration part 76 fixed on one side of the shell 71 and in thermal contact with the metal pipe 74 at the refrigeration end. The semiconductor refrigeration part 76 is used for refrigerating the metal pipe 74 to supply cold air flow to the second air port 6.
[0062] In an embodiment provided by the present application, the air supply part 7 further comprises a heat conducting sleeve 75 fixed between the metal pipe 74 and the semiconductor refrigeration part 76, an air pump 73 fixed at the end of the shell 71 and having an output end connected with the first end of the metal pipe 74, and a fan 72 fixed outside the semiconductor refrigeration part 76; the second end of the metal pipe 74 is connected with the second air outlet 6 through a hose. The heat conducting sleeve 75 is used to transfer the refrigeration capacity to the metal pipe 74, the air pump 73 is used to supply air to the metal pipe 74, and the fan 72 is used to promote heat dissipation of the heat dissipation end of the semiconductor refrigeration part 76. The air pump 73 can be a micro air pump.
[0063] By adopting the above technical scheme, when the ice blocks in the cooling filling cavity 35 cannot achieve heat conduction cooling, the skin can be cooled by cold air flow. In the present application, the air supply part 7 designed to be used with the plastic restraint belt 1 is used to supply cold air flow. According to actual conditions, the air supply part 7 can also be selected with a cold air flow supply device. The working principle of the air supply part 7 is as follows: the air pump 73 works to pump air into the metal pipe 74, the fan 72 is used to dissipate heat from the hot end of the semiconductor refrigeration part 76, the cold end of the semiconductor refrigeration part 76 is tightly attached to one side of the heat conducting sleeve 75, and the cold capacity is efficiently conducted to the metal pipe 74 through the heat conducting sleeve 75. The metal pipe 74 (which needs to have good heat conductivity, such as copper or aluminum) absorbs the cold capacity of the cold end, the temperature is reduced, the gas flowing through the metal pipe 74 contacts the inner wall of the low-temperature metal pipe 74, heat exchange occurs, the temperature of the gas is reduced, the cold air flow is discharged from the metal pipe 74 into the second air outlet 6, the cold air flow enters the flow channel through the second air outlet 6, and finally is discharged from the air outlet 5 to blow on the outer skin for cooling. According to the requirements, the skin can be cooled and analgesic treatment at any time, the skin sweating is reduced and the humidity is reduced, and the comfort of the skin is improved. It should be noted that how to make the multiple air outlets 5 uniformly blow air belongs to mature prior art. For example, a flow limiting orifice plate or a micro nozzle with the same design can be opened at each air outlet 5. The orifice diameter and the number of orifices are the same. Even if there is a slight difference in the resistance of the branch pipeline, the throttling effect can "pinch" the flow of each branch within the same range. Here, further description is omitted.
[0064] In an embodiment provided by the present application, the magic bonding assembly comprises an extension belt 16 integrally formed at one end of the plastic restraint belt 1, a first magic tape 17 fixed on one side of the extension belt 16, a second magic tape 18 fixed on one side end of the plastic restraint belt 1 and used for bonding with the first magic tape 17, and a slot 15 provided at the other end of the plastic restraint belt 1 and used for the extension belt 16 to pass through and move. By making the extension belt 16 pass through the slot 15 and bend, the first magic tape 17 and the second magic tape 18 are bonded, and the action of wrapping the plastic restraint belt 1 on the skin surface can be completed.
[0065] By adopting the technical scheme, the plastic binding belt 1 is placed on the skin surface, the extension belt 16 is passed through the slot 15 and bent, the first magic tape 17 is bonded with the second magic tape 18, and the action of wrapping the plastic binding belt 1 on the skin surface is completed. When the plastic binding belt 1 is bound on the skin, the plurality of first supporting parts 3 are located between the plastic binding belt 1 and the skin and bear the main load, so that the first supporting part 3 can lift the plastic binding belt 1 after the plastic binding belt 1 is tightened, the gap between the plastic binding belt 1 and the skin is generated, and the gap height between the plastic binding belt 1 and the skin is maintained. The plurality of circular supporting parts 11 are in contact with the skin to realize point pressure buffering (by the lower elastic modulus and moderate compression deformation, the point high pressure is uniformly diffused to a larger contact surface, the single-point pressure peak is reduced, the risk of local necrosis or nerve compression of the skin is reduced, and the compression force is dispersed), and the belt body can be inhibited from slipping along the arm. The cooperation of the first supporting part 3 and the second supporting part 11 can make the plastic binding belt 1 and the skin exist a certain gap, and the gap between the plurality of second supporting parts 11 can also form a ventilation channel, accelerate evaporation of sweat, let the skin release water vapor and heat have an outlet, reduce the risk of sweat and skin immersion, and avoid forming a high-humidity environment between the skin and the binding belt.
[0066] Further, the first supporting part 3 can be arranged along the width direction of the plastic binding belt 1, and the second supporting part 11 can be circular.
[0067] The working process of the technical scheme is as follows:
[0068] The first supporting part 3 is cooled in advance and installed in the freezer, the moisture-absorbing outer sleeve 33 is sleeved on the outside of the first supporting part 3, then the first supporting part 3 is bonded with the plastic binding belt 1 through the magic tape (the third magic tape 31 and the fourth magic tape 32), the plastic binding belt 1 is placed on the skin surface, the extension belt 16 is passed through the slot 15 and bent, the first magic tape 17 is bonded with the second magic tape 18, the action of wrapping the plastic binding belt 1 on the skin surface is completed, the plurality of first supporting parts 3, the plurality of anti-skid parts 13 and the moisture-absorbing outer sleeve 33 are in contact with the skin surface, the skin surface is cooled by the solidified liquid (ice block) in the cooling filling cavity 35, then the gas pump pumps the gas into the first gas port 21, the gas enters the compression air bag 2 from the first gas port 21, the compression air bag 2 expands and compresses the skin around the wound, and local compression of the wound is realized. When the liquid solidification (ice block) loses the cooling capacity and needs to cool the skin surface, the gas supply part 7 can supply the cold gas flow to the second gas port 6, the cold gas flow enters the flow channel through the second gas port 6, and finally is discharged from the gas outlet 5 to blow on the outer skin for cooling.
