Description

Technical Field

[0001] The invention relates to the technical field of bone injury cold and hot compress, and in particular to a bone injury cold and hot compress device. Background Art

[0002] The bone injury cold and hot compress device is a medical device that integrates physical therapy with modern technology. It is mainly used to provide local cold or hot compress treatment, and can apply a certain amount of pressure to help relieve pain, reduce swelling, stop seepage and promote blood circulation. The bone injury cold and hot compress device uses a PN junction made of semiconductor materials and uses the Peltier effect for cooling or heating. This cooling / heating method does not require the use of traditional refrigerants (such as Freon), so it will not cause environmental pollution and is almost silent when working.

[0003] After searching, the Chinese patent with publication number CN220558169U discloses a hot and cold compress device for bone injuries in traditional Chinese medicine, including a tray, a cooling pool, a stirring blade, an insulation bucket, a heating box, a pad, an insulation belt, a placement bag, a restraining belt, a bottom plate, a column, a sliding plate, a trigger bucket, a connecting block, a storage hopper and a crossbeam. Through the setting of the cooling pool and the heating box, the mixing of ice and water can be accelerated through the action of the stirring blade, thereby facilitating cold compressing the patient, and the entire Chinese medicine bag is fixed to the bone injury by steam heating of the Chinese medicine bag and then by binding with the restraining belt. At the same time, the heat loss of the heated Chinese medicine bag is prevented from being too fast through the action of the insulation belt, thereby affecting the entire hot compress treatment. However, when using this technical solution, there are still the following defects:

[0066] like Figures 1 to 8As shown, the bone injury cold and hot compress device includes a main body 1; a fixed frame 2, fixedly mounted on the top surface of the main body 1; a covering bag 3, arranged on the inner side of the fixed frame 2; two adhesive connection belts 4, symmetrically fixedly mounted on the covering bag 3; two clearance openings 5, symmetrically opened on the top surface of the fixed frame 2, and the clearance openings 5 ​​are adapted to the adhesive connection belts 4; a retractable and reeling assembly, arranged on the fixed frame 2, for contacting the covering bag 3; a bottom plate 7, slidably mounted on the inner side wall of the fixed frame 2; a transmission assembly, arranged on the main body 1, and the transmission assembly cooperates with the retractable and reeling assembly to disinfect the covering bag 3; a supporting mechanism, arranged on the top surface of the bottom plate 7, for supporting the retractable and reeling assembly; a spraying assembly, arranged on the bottom plate 7, for spraying alcohol;

[0067] When applying hot or cold compresses to the injured bone, the covering bag 3 can be placed at the injured bone of the patient, and the covering bag 3 can be fixed by two adhesive connecting belts 4, and then the covering bag 3 can be connected to the main body 1 through a pipe to apply hot or cold compresses to the injured bone. After use, the covering bag 3 can be removed and placed in the fixing frame 2, and the two adhesive connecting belts 4 at both ends of the covering bag 3 can be placed in the yielding opening 5 to limit the covering bag 3. Subsequently, the contact surface between the covering bag 3 and the patient's skin can be disinfected through the transmission assembly, the supporting mechanism and the spraying assembly. After the treatment is completed, the retractable and rewinding assembly can be opened to dry the covering bag 3 so that it can be quickly put into use again.

[0068] like Figure 2 , Figure 3 , Figure 4 , Figure 8 As shown, the unwinding and rewinding assembly includes: an unwinding roller 61, which is rotatably mounted on one end of the fixed frame 2 through a bracket; a torsion spring 62, which is sleeved on one end of the unwinding roller 61; a rewinding roller 63, which is rotatably mounted on the end of the fixed frame 2 away from the unwinding roller 61 through a bracket; a servo motor 64, which is fixedly mounted on the bracket through a fixing frame, and the servo motor 64 corresponds to the rewinding roller 63; an output shaft 65, which is fixedly mounted on the output end of the servo motor 64; a one-way bearing 66, which is fixedly sleeved on the end of the output shaft 65 away from the servo motor 64, and the end of the rewinding roller 63 is sleeved on the one-way bearing 66; a paper roll 67, which is sleeved on the unwinding roller 61, and the end of the paper roll 67 passes through the fixed frame 2 and is fixedly connected to the rewinding roller 63, and the paper roll 67 is composed of cotton soft paper and fiber paper distributed in a staggered linear array;

[0069] When the covering bag 3 is placed in the fixed frame 2 after use, it can be directly placed on the fiber paper part of the paper roll 67 located in the fixed frame 2. The fiber paper can support the covering bag 3, and during the alcohol spraying and disinfection process, the fiber paper can be quickly moistened by alcohol and then contact the covering bag 3 in all aspects for disinfection. After the covering bag 3 is disinfected, the servo motor 64 can be turned on for forward rotation. This direction is the locked state of the one-way bearing 66. Therefore, when the servo motor 64 is turned on, the output shaft 65 can be used to drive the winding roller 63 to rotate so as to wind up the paper roll 67 part in the fixed frame 2. As the winding progresses, the fiber paper can be wound around the winding roller 63, and the cotton and soft paper part on the paper roll 67 can enter the fixed frame 2 and contact the bottom surface of the covering bag 3, and absorb moisture and dry the disinfected surface of the covering bag 3 so that it can be put into use quickly.

[0070] like Figure 3 , Figure 5 As shown, the transmission assembly includes: a guide groove 81, which is opened on the top surface of the main body 1; a driving screw 82, which is rotatably mounted on the inner side wall of the guide groove 81, and one end of the driving screw 82 passes through the main body 1; a guide block 83, which is threadedly mounted on the outer wall of the driving screw 82, and the guide block 83 is slidably connected to the guide groove 81, and the top surface of the guide block 83 is fixedly connected to the bottom surface of the bottom plate 7; a driven wheel 84, which is fixedly mounted on one end of the driving screw 82 located outside the main body 1; a one-way bearing 85, which is mounted on the outer wall of the output shaft 65, and the locking direction of the one-way bearing 66 is opposite to that of the one-way bearing 85; a synchronous belt 86, which is mounted on the outer wall of the one-way bearing 85 and the driven wheel 84;

[0071] During the process of disinfecting the coated bag 3, the servo motor 64 can be reversed. This direction is the locking direction of the one-way bearing 2 85, and the one-way bearing 1 66 is in a free state. Therefore, the output shaft 65 can drive the one-way bearing 2 85 to rotate and drive the driving screw 82 to rotate through the synchronous belt 86 and the driven wheel 84. Since the guide block 83 is threadedly mounted on the driving screw 82 and the guide block 83 is slidably connected to the guide groove 81, when the driving screw 82 rotates, it can drive the guide block 83 to slide back and forth along the guide groove 81, thereby driving the base plate 7.

[0072] like Figures 5 to 7 As shown, the support mechanism includes: two guide frames 91, which are fixedly mounted on the two ends of the top surface of the bottom plate 7, and the side surfaces of the guide frames 91 are in contact with the inner side walls of the fixed frame 2; two support plates 92, which are slidably mounted on the inner side walls of the two guide frames 91; two groups of springs 93, which are fixedly mounted between the bottom surfaces of the two support plates 92 and the inner bottom walls of the guide frames 91; two top rollers 94, which are symmetrically rotatably mounted between the opposite side surfaces of the two support plates 92, and the outer surface walls of the top rollers 94 are in contact with the bottom surface of the paper roll 67;

[0073] During the sliding process of the bottom plate 7, under the support of the spring 93, the two top rollers 94 between the support plates 92 can contact the bottom surface of the paper roll 67, so that the paper roll 67 is pressed tightly and fully contacts the bottom surface of the covering bag 3, thereby achieving all-round disinfection of the use surface of the covering bag 3.

[0074] like Figure 2 , Figure 5 , Figure 6 As shown, the spray assembly includes: a water supply pipe 101, fixedly mounted on the top surface of the bottom plate 7; a plurality of alcohol nozzles 102, distributed in a linear array on the outer wall of the water supply pipe 101, and the alcohol nozzles 102 are connected to the water supply pipe 101, the horizontal position of the alcohol nozzles 102 is at least lower than the horizontal position of the top roller 94, and the alcohol nozzles 102 are vertically arranged with the bottom plate 7; a liquid storage tank 103, fixedly mounted on the side of the main body 1, and the liquid storage tank 103 is filled with medical alcohol; a liquid supply pump 104, arranged on the side of the main body 1 above the liquid storage tank 103; two conduits 105, respectively arranged between the liquid supply pump 104 and the water supply pipe 101 and the liquid storage tank 103;

[0075] During the sliding process of the bottom plate 7, the liquid supply pump 104 is simultaneously turned on to spray the alcohol in the liquid storage tank 103 along the alcohol nozzle 102 onto the fiber paper through the conduit 105, so as to quickly soak the fiber paper. At the same time, with the tightening of the top roller 94, the fiber paper can contact the bottom surface of the coating bag 3 and be disinfected by alcohol.
