Description

Technical Field

[0001] The invention relates to the technical field of fistula protection instruments, in particular to an intelligent Bianstone ironing and massaging fistula protection instrument with real-time feedback regulation. Background Art

[0002] Most patients with end-stage renal disease use hemodialysis as renal replacement therapy. Autologous arteriovenous fistula is a vascular access that surgically anastomoses arteries and veins. After venous arterialization, the blood flow in the blood vessels increases to meet the needs of dialysis treatment. It is also the preferred access recommended by international guidelines and domestic expert consensus. Patients undergo dialysis treatment at least 2-3 times a week, and each treatment routinely requires 2 fistula punctures. Long-term puncture causes damage to the vascular endothelium, and the inflammatory state causes fibrotic changes in endothelial cells, which are more likely to cause complications such as thrombosis and intimal hyperplasia. However, excessive hyperplasia cannot be prevented during the remodeling and hyperplasia process. In addition, there are other complications such as infection and pseudoaneurysm. Fistulas are ultimately exhaustible resources with a high incidence of dysfunction. The 2-year patency rate is 48%-56%, which increases the patient's pain and economic burden.

[0003] Therefore, daily maintenance of arteriovenous fistula is particularly important. Relevant evidence shows that physical therapy such as far-infrared irradiation and Chinese medicine acupoint massage and hot compress therapy can improve the patency rate of fistula, increase the long-term use period, and are more conducive to protecting the patient's fistula. Bianstone is a Chinese medicine stone tool made of Sibin pumice. It contains more than 30 trace elements and can produce rich ultrasonic pulses. It has several biophysical effects such as induced warming, infrared radiation, and ultrasonic pulses. The use of electric Bianstone heat therapy plus massage has a good effect in reducing joint pain and inflammatory response in patients with cervical vertigo and frozen shoulder. In the comparative observation of the effect on the blood perfusion of meridian points, it was found that acting on the He point can increase the blood flow of the original point of the meridian.

[0004] Based on the above research evidence, a technical solution for Bianstone ironing and fistula protection instrument is proposed. Bianstone particles are added to the main body and combined with electric heating elements, so that the Bianstone particles are in contact with the patient's arm skin, and the constant temperature hot compress is maintained while giving full play to the biophysical effect of Bianstone, which can improve microcirculation and inflammation, relieve pain, etc., thereby achieving good functional protection of the autologous arteriovenous fistula, promoting the maturation of the fistula, reducing complications, and reducing the failure rate of the fistula.

[0005] The existing fistula protection technology uses Velcro to wrap and bind the patient's arm with appropriate tightness, and the patient can freely adjust the tightness by tearing the Velcro. However, the fistula blood vessels of patients with long-term dialysis are not completely straight, and pseudoarteriovenous aneurysms can cause local bulges in the fistula puncture area. Some patients even have multiple pseudoaneurysms in their fistulas. Therefore, uneven temperature and pressure will occur during the hot compress process, and targeted care cannot be performed. When the arm is moved during the hot compress, the muscle movement inside the arm will cause the fistula protection device to be unable to effectively fit the arm and affect the blood circulation in the patient's arm. Therefore, in order to solve the above problems, an intelligent Bianstone ironing and fistula protection device with real-time feedback control is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent Bianstone ironing and fistula protection device with real-time feedback control, which aims to improve microcirculation and inflammatory state, analgesia and other functional protections for the autologous arteriovenous fistula of hemodialysis patients by exerting the biophysical effect of Bianstone and combining it with constant temperature hot compress of electric heating elements, so as not to affect the blood circulation of the patient's arm while carrying out targeted care. Through the set pressure sensor and pressure control component, the restraining force of the fistula protection device is automatically adjusted when the pressure sensor detects the pressure change, so that the Bianstone can effectively fit the arm, and the heat can be gathered and guided at the position where the pressure sensor has a large deformation pressure, improving the hot compress effect while ensuring the blood circulation effect of the patient's arm.

[0007] To achieve the above object, the present invention provides the following technical solutions: An intelligent Bianstone ironing and massaging fistula protection instrument with real-time feedback regulation, comprising a base cloth, a fistula protection instrument body, a central control switch and an ironing and massaging sheet, wherein the fistula protection instrument body is arranged on the base cloth, the central control switch is arranged on one side of the base cloth, the ironing and massaging sheet is arranged on the fistula protection instrument body, and further comprising a winding roller, a winding assembly, a heat-insulating pad, an air pipe, a pressure sensor and a pressure regulating assembly, wherein the winding roller and the winding assembly are both arranged at the left end of the base cloth, the winding roller is fixedly connected to the base cloth, and the ironing and massaging sheet is in contact with the patient's arm when the patient's arm is in contact with the patient's arm. The winding component winds up the base cloth 1 at different speeds at the front and rear ends through a winding roller, the pressure sensor is arranged on the fistula protection device body, the thermal insulation gasket is arranged between the base cloth 1 and the fistula protection device body and is hollow, the air pipe is arranged below the base cloth 1 and the right end thereof passes through the interior of the thermal insulation gasket, the pressure regulating component is cooperatively connected with the left end of the air pipe, and when the pressure of the pressure sensor increases or decreases after the ironing plate is attached to the arm, the pressure regulating component draws air or delivers air to the interior of the thermal insulation gasket through the air pipe.

[0008] Preferably, the winding assembly includes a hollow column, a sleeve, a driving rod, a hook, an elastic cloth strip and a driving assembly, the side wall of the hollow column is provided with an opening, the winding roller is coaxially arranged inside the hollow column, the sleeve is passed through the interior of the winding roller and the hollow column, the winding roller is fixedly sleeved with the sleeve, the diameter of the winding roller is arranged to increase from front to back, the left end of the base cloth 1 is passed through the interior of the opening, the hook is arranged on the surface of the hollow column, the elastic cloth strip is arranged on the lower surface of the base cloth 1 and a plurality of hanging sections are left, the hook matches the hanging section, the driving rod is arranged at the front end of the hollow column and connected to the sleeve, the driving assembly is arranged on the driving rod, and after the hook is hung with the hanging section, the driving assembly tightens the base cloth 1 through the sleeve.

[0009] It can be seen that the thickness of the front and rear ends of a person's forearm is different. When using the existing fistula protector, the front end of the forearm often cannot be tightly wrapped, resulting in heat loss during the hot compress process, and it is impossible to achieve effective hot compress for the entire forearm. Therefore, this solution is adopted. During the rotation of the winding roller, the rear end of the base fabric 1 can be rolled up at a faster speed than the front end, thereby reducing the rear end length of the base fabric 1, so that after the fistula protector body wraps the arm, the front and rear ends can be fitted, that is, the fitting effect of the ironing sheet and the arm is guaranteed, thereby achieving effective improvement of the hot compress effect, that is, effective improvement of the blood circulation effect of the arm.

[0010] Preferably, the ironing sheet includes a second base fabric, a Bian stone, a non-woven fabric, a first Velcro and a second Velcro, the second base fabric is arranged above the pressure sensor, the pressure sensor is a thin film pressure sensor, a plurality of the Bian stones are arranged in an "I" shape, the Bian stone array is passed through the interior of the second base fabric and is bonded to the surface of the pressure sensor, the non-woven fabric is arranged above the Bian stone and has flanges on both the left and right ends, the first Velcro is arranged on the upper surface of the first base fabric, the second Velcro is arranged on the lower surface of the second base fabric, and the first Velcro is connected with the second Velcro.

[0011] It can be seen that during the hot compress process, the fistula protector body covers the forearm position of the entire arm, and the pressure on the entire forearm needs to be detected, so this solution is adopted. Under the action of the thin film pressure sensor, the arm coverage detection can be realized. When the pressure detected during the hot compress process is not within the setting range of the thin film pressure sensor, the restraining pressure can be automatically regulated, that is, when the pressure detected during the hot compress process exceeds the maximum value set by the thin film pressure sensor, the restraining force of the fistula protector body can be automatically reduced, and when the pressure detected during the hot compress process exceeds the minimum value set by the thin film pressure sensor, the restraining force of the fistula protector body can be automatically increased, thereby ensuring that the fistula protector body is always maintained within a stable pressure range during the hot compress process, and then effectively ensuring the hot compress effect, that is, ensuring the blood circulation effect of the arm.

[0012] Preferably, the pressure regulating component includes a two-way air pump, which is connected to a pressure sensor. The two-way air pump is arranged on the outer wall of the hollow column, the port of the two-way air pump is connected to the left end of the air pipe, and the right end of the air pipe passes through the interior of the thermal insulation gasket.

[0013] By adopting the above scheme, during the hot compress process, a two-way air pump can be used to supply and exhaust air inside the thermal insulation gasket to achieve pressure regulation inside the thermal insulation gasket, thereby achieving automatic adjustment of the arm restraint pressure. When the patient moves his arm during the hot compress process, when the pressure increases, the restraint pressure of the fistula protector is actively reduced to avoid affecting the blood flow of the arm. When the pressure decreases, the restraint pressure of the fistula protector is actively increased, thereby ensuring the effective fit of the Bianstone and the arm, and then ensuring the hot compress effect, that is, ensuring the blood circulation effect of the arm.

[0014] Preferably, the driving assembly includes a gear, a disc and an elastic telescopic rod, the interior of the sleeve is provided with a communicating retention hole and an annular tooth groove, the gear is meshingly arranged inside the annular tooth groove and fixedly sleeved with the driving rod, the disc is arranged at the front end of the driving rod, the elastic telescopic rod is arranged between the hollow column and the disc and the front end is arranged in a wedge shape, the rear end of the elastic telescopic rod is fixedly connected to the hollow column, the front end of the elastic telescopic rod is in contact with the disc, and a plurality of slots are arranged on the rear side of the disc, each of the slots cooperates with the front end of the elastic telescopic rod.

[0015] It can be seen that the method of binding the fistula protection device body with Velcro is convenient and fast, and is suitable for patients to use alone. Considering that the fistula protection device body needs to be removed by unsticking the Velcro after the hot compress is completed, and the fistula protection device body will cause the patient's arm to be compressed during the one-handed operation, resulting in poor blood flow inside the arm, so this solution is adopted. After the hook and the hooking section are hooked, the winding roller can be quickly driven to rotate to achieve the effect of winding up the base cloth 1, and then the fistula protection device body is bound to the arm. After the hot compress is completed, the gear and the annular tooth groove can be separated to contact the limiting effect of the sleeve, so that the base cloth 1 can be pulled out from the inside of the hollow column, which will not cause compression to the patient's arm, and ensure the normal flow and circulation of blood inside the arm.

[0016] Preferably, a plurality of air holes 1 are formed on the surface of the pressure sensor, a plurality of bonding points are provided on the thermal insulation gasket, and an air hole 2 is formed in the middle of each bonding point.

[0017] By adopting the above scheme, heat loss can be reduced during the hot compress process to ensure the hot compress effect on the arm, and the breathability effect can be avoided during the hot compress process, that is, the discomfort caused to the patient by stuffiness can be reduced while ensuring the blood circulation effect inside the arm.

[0018] Preferably, a placement groove is provided on the surface of the pressure sensor, a radial cross-section of the placement groove is arranged in an arc shape, and a graphene film is arranged inside the placement groove.

[0019] By adopting the above scheme, the heat generated by the fistula protector body during hot compress can be gathered under the action of the placement groove and the graphene film, thereby improving the hot compress effect and further improving the blood circulation effect in the arm.

[0020] Preferably, a plurality of placement grooves are arranged in a linear array along the long sides of the pressure sensor.

[0021] It can be seen that after multiple dialysis sessions, the patient's arm will have a pseudoaneurysm bulge in the fistula, and after the bulge, it will be distributed along the length of the arm, so this solution is adopted. When wrapping the fistula protector body on the arm with the bulge, the position of the bulge will increase the curvature of the fistula protector body, that is, increase the curvature of the placement slot on the pressure sensor, so that the heat can be further gathered under the action of the graphene film in the curved slot, further increasing the hot compress temperature at the fistula, thereby effectively improving the hot compress effect, that is, improving the blood circulation effect of the arm.

[0022] Preferably, a servo motor is provided at the end of the hollow column, the output end of the servo motor passes through the interior of the hollow column and is connected to a driving block, the driving block is rotatably connected to the end of the sleeve, a lever is provided on the side wall of the driving block, and the distance between the lever and the axis of the hollow column is arranged to increase from front to rear.

[0023] By adopting the above solution, when the servo motor is working, it can drive the lever to reciprocate and press the end of the base cloth 1 located inside the hollow column at a small distance, so that the base cloth 1 is driven to move reciprocally inside the opening under the action of the elastic cloth strip, so as to achieve massage of the patient's arm. When used in conjunction with the traditional Chinese medicine fistula-protecting ointment for promoting blood circulation and removing blood stasis, massage can better promote the penetration and absorption of the medicine, thereby exerting the superimposed therapeutic effect of Bianstone + hot compress + traditional Chinese medicine preparation.

[0024] Compared with the prior art, the present invention has the following beneficial effects: 1. The main body adds Bianstone particles that are more suitable for fistula arms and combines them with electric heating elements to ensure effective fitting, better exert the biophysical effects of Bianstone while maintaining constant temperature hot compress, and produce effects such as improving microcirculation and inflammatory status, and relieving pain.

[0025] 2. By setting up a pressure sensor and a placement groove opened along the width direction on the surface of the pressure sensor, and cooperating with a graphene film installed inside the placement groove, the bending effect of the corresponding arc groove can be increased when the pressure sensor is severely bent due to the raised part of the patient's arm, so that the arc groove and the graphene film can be used to gather the heat emitted by the fistula protection device body, and the direct contact between the pressure sensor and the Bian stone can be used to conduct the gathered heat to the corresponding Bian stone, so that the hot compress temperature at the fistula of the patient's arm is slightly higher than the temperature of other parts, thereby effectively ensuring the hot compress effect at the fistula, and effectively ensuring the blood circulation effect of the patient's arm.

[0026] 3. By setting the driving component, under the condition of the wedge-shaped setting of the front end of the elastic telescopic rod, the unidirectional rotation of the disc can be limited, so that after the fistula protector body and the arm are wrapped, the meshing of the gear and the annular tooth groove can be utilized to retract the base cloth into the hollow column at a speed greater than the front end at the rear end when the driving rod is rotated, so that after the fistula protector body is bound, the fit of the fistula protector body and the arm can be ensured, avoiding the situation that the front end of the Bian stone cannot effectively fit the arm due to the different thickness of the front and back ends of the patient's arm. At the same time, after the hot compress is completed, the disc can be pressed until the gear and the tooth groove are separated, so as to achieve the rapid separation of the hook and the hanging section, avoiding the patient's arm being compressed when the fistula protector is released after using it alone for nursing. A servo motor is arranged at the end of the hollow column. When the servo motor is working, it can drive the lever to reciprocate and press one end of the base cloth located inside the hollow column at a small distance, so that the base cloth is driven to move back and forth inside the opening under the action of the elastic cloth strip, thereby massaging the patient's arm. While applying hot compress, it can also play the role of traditional Chinese medicine massage therapy in improving the patency rate of internal fistula and increasing the long-term use period.

[0027] 4. Through the set pressure sensor and pressure regulation component, the coverage detection of the patient's arm can be realized. When the pressure is detected to exceed the set pressure range of the pressure sensor during the hot compress process, the central control switch can directly detect the feedback, and when the pressure is greater than the set pressure range of the pressure sensor, the two-way air pump is automatically started to extract the air stored in the thermal insulation gasket through the trachea to reduce the restraining pressure on the arm. When the pressure is less than the set pressure range of the pressure sensor, the two-way air pump is automatically started and the air is transported to the inside of the thermal insulation gasket through the trachea, thereby increasing the restraining pressure on the arm, thereby increasing the number of contacts between the Bianstone and the arm, and then effectively ensuring the hot compress effect, that is, ensuring the blood circulation effect of the patient's arm.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 9 The present invention provides an intelligent Bianstone massage and fistula-preventing device with real-time feedback control, and the technical solution is as follows: For details, please refer to Figure 1 and Figure 2, an intelligent Bianstone ironing and massage fistula protection instrument with real-time feedback control, comprising a base fabric 1, a fistula protection instrument body 2, a central control switch 3 and an ironing and massage sheet 4, the fistula protection instrument body 2 is arranged on the base fabric 1, the central control switch 3 is arranged on one side of the base fabric 1, the ironing and massage sheet 4 is arranged on the fistula protection instrument body 2, and also includes a winding roller 5, a winding component 6, a heat preservation pad 7, an air pipe 8, a pressure sensor 9 and a pressure control component 10, the ironing and massage sheet 4 includes a base fabric 2 41, a Bianstone 42, a non-woven fabric 43, a magic The first sticker 44 and the second Velcro 45, the second base fabric 41 is arranged above the pressure sensor 9, the pressure sensor 9 is a thin film pressure sensor, and the Bian stone 42 is arranged in a plurality and all in the shape of an "I". The Bian stone 42 array is arranged inside the second base fabric 41 and fits the surface of the pressure sensor 9. Each Bian stone 42 is independently arranged, and its size and thickness can be freely selected according to the patient's needs, which helps to achieve a more uniform pressure distribution and avoid pain or discomfort caused by excessive local pressure. At the same time, since each Bian stone 42 is independently arranged, the patient can freely disassemble and assemble the Bian stone 42 at any time according to the required size, so as to adjust the number and installation position of the Bian stone 42 according to the actual use needs, so as to achieve the effect of local ironing and massaging the fistula position or the whole fistula arm. The non-woven fabric 43 is arranged above the Bian stone 42 and has flanges 431 at both the left and right ends. Velcro 1 44 is arranged on the upper surface of the base fabric 1 1 , and Velcro 2 45 is arranged on the lower surface of the base fabric 2 41 . Velcro 1 44 and Velcro 2 45 are connected in cooperation.

[0032] Under the above-mentioned setting conditions, during the process of wrapping the fistula protector around the patient's arm, the pressure sensor 9 can be bent. After the fistula protector is restrained, the bending state of the pressure sensor 9 is fixed. At this time, the hollow switch can obtain the restraining force of the fistula protector on the arm according to the pressure detected by the pressure sensor 9, so that the patient can choose the appropriate hot compress pressure according to his own situation. During the hot compress process, when the patient moves his arm, the pressure sensor 9 can feed back the detected pressure changes to the central control switch 3 in real time, so that the patient can always pay attention to the pressure on the arm during the hot compress, so as to avoid severe compression of the fistula and affect the blood circulation effect.

[0033] As an embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 4The winding roller 5 and the winding assembly 6 are both arranged at the left end of the base fabric 1, the winding roller 5 is fixedly connected to the base fabric 1, the pressure sensor 9 is arranged on the fistula protection instrument body 2, the winding assembly 6 includes a hollow column 61, a sleeve 62, a driving rod 63, a hook 64, an elastic cloth strip 65 and a driving assembly 66, the side wall of the hollow column 61 is provided with an opening 611, the winding roller 5 is coaxially arranged inside the hollow column 61, the sleeve 62 is penetrated inside the winding roller 5 and the hollow column 61, the winding roller 5 is fixedly sleeved with the sleeve 62, and the winding The diameter of the roller 5 is set to increase from front to back, the left end of the base fabric 1 is inserted into the inside of the opening 611, the hook 64 is set on the surface of the hollow column 61, the elastic cloth strip 65 is set on the lower surface of the base fabric 1 and has multiple hanging sections 651, the hook 64 matches the hanging section 651, the driving rod 63 is set at the front end of the hollow column 61 and connected to the sleeve 62, the driving component 66 is set on the driving rod 63, and after the hook 64 is hung with the hanging section 651, the driving component 66 tightens the base fabric 1 through the sleeve 62.

[0034] Since the thickness of the front and back ends of the patient's arm are different, under the above-mentioned setting conditions, in the process of driving the winding roller 5 to rotate, the left end of the base cloth 1 can be rolled up, and the rolling speed of the rear end of the base cloth 1 is made greater than that of the front end. Then, after the fistula protector is wrapped around the arm, the hook 64 is hung with the hanging section 651 of the elastic cloth strip 65, and the winding roller 5 is continued to rotate. Therefore, when the front and back ends of the patient's arm are different in thickness, the front and back ends of the arm can be effectively wrapped, so that multiple Bian stones 42 can be effectively fitted with the arm, thereby improving the hot compress effect on the arm, that is, improving the blood circulation effect of the patient's arm.

[0035] As an embodiment of the present invention, refer to Figure 4 , Figure 5 and Figure 6 The driving assembly 66 includes a gear 661, a disc 662 and an elastic telescopic rod 663. The interior of the sleeve 62 is provided with a connected retention hole 621 and an annular tooth groove 622. The gear 661 is meshedly arranged inside the annular tooth groove 622 and fixedly sleeved with the driving rod 63. The disc 662 is arranged at the front end of the driving rod 63. The elastic telescopic rod 663 is arranged between the hollow column 61 and the disc 662 and the front end is set in a wedge shape. The rear end of the elastic telescopic rod 663 is fixedly connected to the hollow column 61, and the front end of the elastic telescopic rod 663 is in contact with the disc 662. A plurality of slots 6621 are arranged on the rear side of the disc 662, and each slot 6621 cooperates with the front end of the elastic telescopic rod 663.

[0036] Under the condition of the wedge-shaped setting at the front end of the elastic telescopic rod 663, after it is plugged into the slot 6621, the disc 662 can be limited, so that the disc 662 can only rotate in one direction. When the disc 662 is driven to rotate clockwise, the engagement of the gear 661 and the annular tooth groove 622 can drive the sleeve 62 to rotate. Since the winding roller 5 is fixedly sleeved on the tube wall of the sleeve 62, the winding roller 5 can be driven to continue to reel in the base cloth 1, thereby binding the entire fistula protector to the patient's arm. After the hot compress is completed, the disc 662 is pressed. Since the gear 661 is connected to the disc 662 through the driving rod 63, the gear 661 can be driven to enter the interior of the retention hole 621 and separate from the annular tooth groove 622 while pressing the disc 662, so that the patient can loosen the entire fistula protector with one hand, avoiding the situation where the arm is compressed during the loosening process and the blood circulation effect of the arm is affected.

[0037] As an embodiment of the present invention, refer to Figure 2 and Figure 3 The pressure regulating component 10 is connected with the left end of the trachea 8, the thermal insulation gasket 7 is arranged between the base cloth 1 and the fistula protection device body 2 and is hollow, the trachea 8 is arranged below the base cloth 1 and the right end thereof passes through the interior of the thermal insulation gasket 7, the pressure regulating component 10 comprises a two-way air pump 101, the two-way air pump 101 is connected with the pressure sensor 9, the two-way air pump 101 is arranged on the outer wall of the hollow column 61, the port of the two-way air pump 101 is connected with the left end of the trachea 8, and the right end of the trachea 8 passes through the interior of the thermal insulation gasket 7.

[0038] Under the above-mentioned setting conditions, when the pressure sensor 9 detects an increase in pressure during hot compress, the two-way air pump 101 is started to extract the air inside the thermal insulation pad 7 through the trachea 8, thereby reducing the pressure in the thermal insulation pad 7, achieving the effect of reducing the restraining force of the fistula protector on the arm, and avoiding the situation where the blood circulation of the patient's arm is affected by the increased restraining force; when the pressure sensor 9 detects a decrease in pressure during hot compress, the two-way air pump 101 is started to transport external air to the inside of the thermal insulation pad 7 through the trachea 8, thereby increasing the pressure in the thermal insulation pad 7, and achieving the effect of increasing the restraining force of the fistula protector on the arm, so that the Bian stone 42 can be kept in close contact with the arm as much as possible, thereby improving the hot compress effect, that is, improving the blood circulation effect of the patient's arm.

[0039] As an embodiment of the present invention, refer to Figure 7 The surface of the pressure sensor 9 is provided with a plurality of air holes 91 , and the heat-insulating gasket 7 is provided with a plurality of bonding points 71 , and the middle of each bonding point 71 is provided with an air hole 2 72 .

[0040] With the help of air hole 1 91 and air hole 2 72, the ventilation effect of the patient's arm can be guaranteed during hot compress, thus avoiding the patient's discomfort caused by poor ventilation effect during the hot compress process.

[0041] As an embodiment of the present invention, refer to Figure 8 A placement groove 92 is provided on the surface of the pressure sensor 9 , the radial cross section of the placement groove 92 is set to an arc shape, a graphene film 93 is provided inside the placement groove 92 , and a plurality of placement grooves 92 are provided in a linear array along the long side of the pressure sensor 9 .

[0042] Under the above-mentioned setting conditions, since the patient's arm will cause fistula bulging after long-term dialysis, the bulging part will increase the bending degree of the pressure sensor 9. Since the pressure sensor 9 detects the change of pressure by the change of resistance value, when the pressure increases (that is, the bending degree of the pressure sensor 9 increases), it will cause the resistance value to increase, which will be accompanied by heat generation. The placement groove 92 is arranged in an arc shape. After bending with the pressure sensor 9, it can cooperate with the graphene film 93 to gather heat, so that the heat at the fistula is slightly higher than other positions, thereby improving the hot compress effect on the patient's arm.

[0043] As an embodiment of the present invention, refer to Figure 1 , Figure 2 and Fig. 9 A servo motor 11 is provided at the end of the hollow column 61, and the output end of the servo motor 11 passes through the interior of the hollow column 61 and is connected to a driving block 12. The driving block 12 is rotatably connected to the end of the sleeve 62. A lever 13 is provided on the side wall of the driving block 12, and the distance between the lever 13 and the axis of the hollow column 61 is set to increase from front to rear.

[0044] Under the above setting conditions, when the servo motor 11 is working, its output end can drive the driving block 12 to rotate reciprocatingly while rotating back and forth. Since the rear end of the lever 13 is connected to the side wall of the driving block 12, the driving block 12 can drive the lever 13 to reciprocate and press the end of the base cloth 1 located inside the hollow column 61 at a small distance when rotating back and forth, so that the base cloth 1 is driven to move back and forth inside the opening 611 under the action of the elastic cloth strip 65, so as to achieve a friction effect on the patient's arm, so that the Bian stone 42 can continuously rub the Chinese medicine ointment on the arm during the hot compress process, and the traditional light pressing hot compress is adjusted to friction hot compress, and further The blood circulation effect of the patient's arm is improved. At the same time, since each Bian stone 42 is independently set, the patient can freely adjust the thickness of the corresponding Bian stone 42 according to the pressure generated on the arm during the friction process to ensure the comfort during nursing. For example, the thickness of the Bian stone 42 is reduced at the fistula, and the thickness of the Bian stone 42 is increased at the non-fistula, which can effectively ensure the tightness and comfort while improving the fistula protection effect. In addition, since the distance between the lever 13 and the axis of the hollow column 61 is set to increase from front to back, the base cloth 1 can be pressed at different trends at the front and back ends of the arm, avoiding the patient's discomfort caused by the different thickness of the front and back ends of the arm.

[0045] Working principle: In order to avoid the different thickness of the front and back ends of the patient's arm, which may cause the fistula protector to be unable to effectively wrap the arm, refer to Figure 1 and Figure 2 By means of the winding roller 5, the length of the base fabric 1 can be pre-adjusted before the fistula protector is wrapped around the arm, and the width of the rear end of the base fabric 1 can be made smaller than the front end during the adjustment process, so that after the arm is wrapped, the front and rear ends of the arm can fit the fistula protector; in order to detect and adjust the restraining pressure in real time during the hot compress, thereby avoiding the pressure change during the hot compress affecting the hot compress effect, refer to Figure 2 and Figure 3 , through the pressure sensor 9 and the pressure regulating component 10, the pressure can be adjusted when the arm is moved during the hot compress process, so as to ensure the effect of the hot compress while avoiding the situation where the blood circulation effect is affected by compressing the arm; in order to avoid compressing the limb when releasing the fistula protection device after the hot compress is completed, refer to Figure 4 and Figure 5 By setting the driving assembly 66, the limit of the winding roller 5 can be quickly released, avoiding the patient's one-handed operation during the release process, which may cause the internal fistula on the arm to be squeezed, and effectively ensures the blood circulation effect of the patient's arm.

[0046] Specifically: attach the non-woven fabric 43 to the upper surface of the base fabric 2 41, and fold the flanges 431 at both ends of the non-woven fabric 43 to the bottom of the base fabric 2 41, and fix the base fabric 1 1 to the upper side of the pressure sensor 9 through the Velcro 1 44 and the Velcro 2 45 to fix the non-woven fabric 43; The disc 662 is rotated clockwise. During the rotation of the disc 662, the gear 661 is driven to rotate through the connection of the driving rod 63. Since the gear 661 is meshed in the annular tooth groove 622, the sleeve 62 can be driven to rotate and the winding roller 5 can be driven to rotate during the rotation of the gear 661. During the rotation of the winding roller 5, the base fabric 1 can be rolled up to achieve pre-adjustment of the length of the base fabric 1. After adjusting to the approximate length, the fistula protector is wrapped around the arm, and the two ends of the base fabric 1 are connected by the hook 64 and the hanging section 651. The disc 662 is continued to be rotated clockwise, so that the entire fistula protector is effectively fixed. The fixed fistula protector body 2 can avoid the situation where the two ends of the patient's arm are different in thickness and cannot be effectively wrapped with the arm. During the hot compress process, the arm and the fistula protector are placed on the table. When the arm needs to be moved during the hot compress process, which causes pressure changes, the pressure sensor 9 can play a role of real-time detection and feedback. When the pressure increases to exceed the setting range of the pressure sensor 9, it can be fed back to the two-way air pump 101. During the operation of the two-way air pump 101, the air in the thermal insulation pad 7 can be extracted through the trachea 8, thereby reducing the restraining pressure and avoiding compression on the patient's arm. When the pressure decreases to exceed the setting range of the pressure sensor, it can be fed back to the two-way air pump 101. During the operation of the two-way air pump 101, the air can be transported to the inside of the thermal insulation pad 7 through the trachea 8, thereby avoiding the loosening of the fistula protector and affecting the hot compress effect, thereby effectively ensuring the blood circulation effect of the patient's arm; When the lever 13 reciprocates in a small range under the action of the servo motor 11 through the driving block 12, the Bian stone 42 can rub the Chinese medicine ointment applied on the arm on the basis of repeatedly pressing down the base cloth 1, thereby improving the nursing effect. In addition, the patient can independently adjust the size and thickness of the Bian stone 42 at the fistula and non-fistula parts of the arm according to the pressure generated during the friction, reduce the pressure of the Bian stone 42 on the fistula, and thus ensure the blood circulation effect of the patient's arm during the nursing process. When the whole fistula protector is released after the hot compress is completed, the disc 662 is pressed, and the disc 662 drives the gear 661 to separate from the annular tooth groove 622 through the driving rod 63. At this time, the sleeve 62 can rotate freely, and then the left end of the base cloth 1 can be drawn to the outside of the hollow column 61 by pulling the hollow column 61, which is convenient for the patient to operate alone and avoids the pressure on the arm in the process of releasing the whole fistula protector, thereby further ensuring the blood circulation effect of the patient's arm.
