DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-10 , the present invention provides five technical solutions: Example 1 See also Figure 1 In an embodiment of the present invention, a geriatric nursing compression hemostasis device includes a spring array layer 1 and a dustproof film 6. A buffer component 3 is provided on the spring array layer 1, which changes the wound compression force by responding to the impact force. A contact component 4 is provided on the buffer component 3, which dynamically fits and moves synchronously with the skin. A release layer 5 for promoting wound healing is provided in the middle of the contact component 4. The dustproof film 6 is provided on the contact component 4 to seal it for dustproof. A binding component 2 is provided on one side of the spring array layer 1.

[0025] See also Figure 2 In an embodiment of the present invention, the spring array layer 1 includes a base layer 11, on which ventilation holes 12 are densely arranged in an array, and a spring member 13 is densely arranged in an array in the middle of the base layer 11. The spring member 13 produces vertical deformation according to changes in body temperature, thereby changing the pressure on the wound.

[0026] See also Figure 2-Figure 3 as well as Figure 5 In an embodiment of the present invention, the spring component 13 includes a memory metal spring 131 and a silicone sleeve 132. The silicone sleeve 132 is wrapped around the memory metal spring 131. A groove 35 is provided at the bottom of the middle layer 31 so that the upper part of the array spring component 13 is located in the groove 35.

[0027] In the above scheme: when the patient's wound is bleeding, the temperature of the wound area will rise, and the temperature of the memory metal spring 131 will exceed 36 degrees, causing the memory metal spring 131 to deform and elongate, thereby pressurizing the buffer component 3, and then the release layer 5 firmly presses the wound. When the bleeding stops, the temperature of the wound area gradually drops. When the temperature of the memory metal spring 131 is lower than 36 degrees, it will deform and return to its original shape, reducing the pressure of the release layer 5 on the wound and improving the patient's comfort.

[0028] For further information, see Figure 2-Figure 3 In the embodiment of the present invention, the memory metal spring 131 undergoes linear deformation and elongation when the temperature is above 36 degrees, and returns to its original length when the temperature is below 36 degrees. The deformation amount is proportional to the temperature change.

[0029] The second embodiment differs from the first embodiment in that: See also Figure 4 In the embodiment of the present invention, the buffer component 3 includes a middle layer 31, the upper part of the middle layer 31 is densely covered with a silicone layer 32, the interior of the silicone layer 32 is a hollow structure, and the hollow structure is filled with a non-Newtonian fluid.

[0030] In the above scheme: when the patient coughs or exercises vigorously, the skin will be instantly tensed, thereby exerting an impact force on the silicone layer 32, and under the action of the non-Newtonian fluid, it will instantly harden, so that the release layer 5 is pressed tightly on the wound to prevent bleeding. When the patient is stable, the non-Newtonian fluid softens, so that the release layer 5 will not be pressed too tightly, ensuring the patient's comfort. When the non-Newtonian fluid is subjected to an instantaneous impact force exceeding 5N, the viscosity of the non-Newtonian fluid increases to 300% of the initial value within 0.3 seconds.

[0031] The third embodiment differs from the first embodiment in that: See also Figure 6-Figure 7 In the embodiment of the present invention, the contact component 4 includes a surface layer 41, and the upper part of the surface layer 41 is densely covered with an array of card slots 42. A ball joint seat 43 is movably hinged in the card slot 42. The upper part of the ball joint seat 43 is provided with a ceramic scale 44 through a clamping part. The rotation angle of the ball joint seat 43 in the card slot 42 is in the range of 0-5 degrees.

[0032] In the above scheme: when the patient needs to exercise, under the action of the ball joint seat 43, the skin will drive the ceramic scales 44 to move as the skin moves, realizing dynamic fitting movement between the skin and the ceramic scales 44, avoiding friction and bleeding caused by the patient's movement.

[0033] For further information, see Figure 6-Figure 7 In an embodiment of the present invention, the clamping portion includes a cross clamping groove 431 arranged at the upper part of the clamping groove 42 and a cross clamping block 441 arranged at the bottom of the ceramic scale 44. The cross clamping block 441 is clamped in the cross clamping groove 431. The damaged ceramic scale 44 can be removed by tweezers and replaced with a new ceramic scale 44, which is convenient for replacement.

[0034] The fourth embodiment differs from the first embodiment in that: See also Figure 8 In the embodiment of the present invention, the release layer 5 includes a bioglass pressing block 51, the interior of the bioglass pressing block 51 is densely covered with storage grooves 52, and the upper part of the bioglass pressing block 51 is densely covered with channels 53 communicating with each storage groove 52, hydrogel microspheres 54 are arranged in the storage grooves 52, and a layer of hydrogel film 55 is provided on the upper part of the bioglass pressing block 51 to close the channel 53.

[0035] In the above scheme: blood dissolves the hydrogel membrane 55, and then contacts the hydrogel microspheres 54 through the channel 53, causing the hydrogel microspheres 54 to gradually dissolve and be released into the wound site, accelerating wound healing. The hydrogel microspheres 54 contain 60% magnesium oxide and 40% calcium oxide, and degrade into irregular particles with a particle size of 0.05 mm within 24 hours in the body fluid environment, promoting wound healing.

[0036] The fifth embodiment differs from the first embodiment in that: See also Figure 1 and Figure 9-10In an embodiment of the present invention, mounting grooves 33 are provided at the upper edges of both sides of the middle layer 31, and optical fiber sensors 34 are installed in the mounting grooves 33. The light-emitting element of the optical fiber sensor 34 is a red optical fiber with a wavelength of 590 mm. The photoelectric receivers on the mounting grooves 33 are periodically arranged at intervals of 1 mm. The optical fiber and the axis of the receiver form a 45° angle to enhance the efficiency of receiving the reflected signal. When the wound bleeds, the light-emitting element of the optical fiber sensor 34 emits red light with a wavelength of 590 mm. This light has good penetrability in human tissue. The photoelectric receivers are periodically arranged at intervals of 1 mm to ensure that the sensor can cover the area around the wound and improve the accuracy of detection. The optical fiber and the axis of the receiver form a 45° angle. This angle setting can enhance the efficiency of receiving the reflected signal. When hemoglobin in the blood absorbs part of the light, the remaining light is reflected back to the photoelectric receiver. When the wound bleeds, the hemoglobin concentration in the blood increases, causing the intensity of the reflected light to change. The photoelectric receiver detects this change and transmits the signal to the microcontroller 26.

[0037] See also Figure 1 and Figure 9-10 In an embodiment of the present invention, the binding assembly 2 includes a cylinder 21, a shaft 22 is rotatably arranged inside the cylinder 21, a binding belt 23 is wound on the shaft 22, one side of the binding belt 23 extends out of the cylinder 21 and is connected to the other side of the spring array layer 1, and the inner side of the binding belt 23 is densely arrayed with micro suction cups 24, and a spiral spring 25 is provided on the outside of one end of the shaft 22. The two ends of the spiral spring 25 are respectively connected to the outside of the shaft 22 and the inside of the cylinder 21. A single-chip microcomputer 26 is provided on the outside of one end of the cylinder 21, and a tightening mechanism 27 is provided on the other end. The mounting slot 33 transmits the monitored red light signal to the single-chip microcomputer 26, and the single-chip microcomputer 26 controls the operation of the tightening mechanism 27.

[0038] See also Figure 1 and Figure 9-10 In this embodiment of the present invention, the tightening mechanism 27 includes an outer cover 271 provided at the end of the cylinder 21 away from the single-chip computer 26, a motor 272 is installed in the outer cover 271, a protrusion 2710 is provided at the bottom of the motor 272, and a movable groove 279 corresponding to the protrusion 2710 is provided on the inner side of the outer cover 271, and the protrusion 2710 is slidably provided in the movable groove 279. One side of the motor 272 is connected to the inner side of the outer cover 271 by a limit spring 276. An electromagnet 278 is provided on the inner side of the outer cover 271 near the movable groove 279, and an iron block 277 is provided on the other side of the motor 272. A limit groove 273 is provided on the side of the inner part of the outer cover 271 away from the protrusion 2710. The output shaft of the motor 272 passes through the limit groove 273 and is connected to the slave gear 274. The tightening mechanism 27 also includes a main gear 275 provided on the outside of the shaft body 22, and the main gear 275 corresponds to the slave gear 274.

[0039] In the above scheme: when in use, pull the binding belt 23, stretch it out, put it on the patient's limb, then tear off the dustproof film 6, align the release layer 5 with the wound and stick it on, then loosen the binding belt 23, and under the elasticity of the spiral spring 25, the spiral spring 25 will automatically shrink, so that the binding belt 23 will automatically retract on the shaft 22, playing a tightening role, so that the release layer 5 is tightly pressed on the wound, and the micro suction cup 24 on the binding belt 23 will be adsorbed on the skin to ensure the stability of the wound pressing. When the wound bleeds, the red blood cells in the blood absorb the wavelength The light is then scattered, and its intensity changes, which is detected by the optical fiber sensor 34 and transmitted to the single-chip microcomputer 26. The single-chip microcomputer 26 makes the electromagnet 278 and the motor 272 work. The electromagnet 278 attracts the iron block 277 on the motor 272, so that the slave gear 274 engages with the main gear 275, and the motor 272 drives the slave gear 274 to rotate. The slave gear 274 drives the main gear 275 to rotate, and the main gear 275 drives the shaft 22 to rotate. The shaft 22 reels the binding belt 23 to tighten it, thereby increasing the pressure on the wound and preventing further bleeding.

[0040] For further information, see Figure 1 and Figure 9-10 In the embodiment of the present invention, the suction force of the electromagnet 278 on the iron block 277 is greater than the elastic force of the limit spring 276. When the iron block 277 is adsorbed on the electromagnet 278, the slave gear 274 is just engaged with the master gear 275.

[0041] Working principle: When in use, pull the binding belt 23, stretch it out, put it on the patient's limb, then tear off the dustproof film 6, align the release layer 5 with the wound and stick it on, then loosen the binding belt 23. Under the elasticity of the spiral spring 25, the spiral spring 25 will automatically contract, so that the binding belt 23 will automatically retract on the shaft 22, playing a tightening role, so that the release layer 5 is tightly pressed against the wound, and the micro suction cup 24 on the binding belt 23 will be adsorbed on the skin to ensure the stability of the wound pressing; The blood dissolves the hydrogel membrane 55 and then contacts the hydrogel microspheres 54 through the channel 53, causing the hydrogel microspheres 54 to gradually dissolve and be released into the wound site, accelerating wound healing. When the patient needs to exercise, under the action of the ball joint seat 43, the skin will drive the ceramic scales 44 to move as the skin moves, achieving dynamic fitting movement between the skin and the ceramic scales 44, avoiding friction bleeding caused by the patient's movement; When the patient coughs or exercises vigorously, the skin will instantly tense, which will exert an impact force on the silicone layer 32. Under the action of the non-Newtonian fluid, it will instantly harden, so that the release layer 5 is pressed tightly against the wound to prevent bleeding. When the patient is stable, the non-Newtonian fluid softens, so that the release layer 5 will not be pressed too tightly, ensuring the patient's comfort. When a patient's wound bleeds, the temperature of the wound site rises, and the temperature of the memory metal spring 131 exceeds 36 degrees Celsius, causing the memory metal spring 131 to deform and elongate, thereby pressurizing the buffer component 3, and thus causing the release layer 5 to firmly press the wound. When the bleeding stops, the temperature of the wound site gradually drops. When the temperature of the memory metal spring 131 drops below 36 degrees Celsius, it deforms and returns to its original shape, reducing the pressure on the wound caused by the release layer 5 and improving the patient's comfort. When the wound bleeds, the red blood cells in the blood absorb light of a certain wavelength and then scatter it, and its intensity changes, which is detected by the optical fiber sensor 34 and transmitted to the single-chip microcomputer 26. The single-chip microcomputer 26 makes the electromagnet 278 and the motor 272 work. The electromagnet 278 attracts the iron block 277 on the motor 272, so that the slave gear 274 engages with the main gear 275, and the motor 272 drives the slave gear 274 to rotate. The slave gear 274 drives the main gear 275 to rotate, and the main gear 275 drives the shaft 22 to rotate. The shaft 22 reels the binding belt 23 to tighten it, thereby increasing the pressure on the wound and preventing further bleeding.
