Description

Technical Field

[0001] The present invention relates to the technical field of cold and hot compress equipment for the shoulder and neck, and in particular to a cold and hot compress device for the shoulder and neck after thyroid surgery. Background Art

[0002] Thyroid surgery is a surgical procedure used to treat thyroid diseases, including thyroid cancer, thyroid nodules, hyperthyroidism, and goiter. The main purpose of surgery is to remove part or all of the thyroid gland to relieve symptoms or treat the disease.

[0003] During thyroid surgery, the neck is in a hyperextended position and the patient is in a supine position for several hours after the operation, which causes tension in the shoulder and neck muscles and soreness and discomfort. In order to reduce the patient's shoulder and neck discomfort after the operation, medical staff usually use hot compress equipment to perform physical therapy on the patient's shoulder and neck.

[0004] At present, although traditional hot compress devices can relieve muscle tension in the patient's shoulder and neck through hot compress, most of them use resistance wire heating. Since resistance wire heating mainly relies on the resistance wire itself to generate heat, and then transfers the heat to the heated object through heat conduction, the heating process is relatively slow. At the same time, the resistance wire is generally hard and has poor flexibility, making it difficult to fit people's shoulder and neck areas.

[0005] Moreover, most of the existing hot compress devices are fixed with Velcro when in use. However, for patients after thyroid surgery, the traditional Velcro fixing method cannot accurately adjust the binding strength of the hot compress device. When the binding strength is light, the hot compress device cannot fit the neck for physical therapy. When the binding strength is large, it is easy to cause breathing difficulties for patients and even aggravate vomiting of patients. In order to enable patients to recover faster, medical staff need to regularly apply cold compresses and change dressings on the wounds on the patients' necks. Traditional Velcro fixing is not convenient for medical staff to change dressings and is easy to cause secondary injuries to patients during the dressing change process. Summary of the invention

[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0019] In the above scheme, the graphene heating layer is used as the core component. In the hot compress mode, by precisely controlling the current size, the graphene can generate heat quickly and stably, and evenly transfer it to the shoulders and neck, promoting local blood circulation, relieving muscle tension and pain. Compared with traditional hot compress devices, graphene heating not only heats up quickly, but also has uniform temperature distribution, avoiding damage to the skin caused by local overheating. At the same time, the graphene heating layer in the heating component is in the shape of a circular tube and integrated into the inside of the heat pipe. Due to the unique triple-helix shape and the mutually intertwined manner of the heat pipe, it can evenly disperse external forces in multiple directions, thereby having high strength and bending resistance, ensuring that the patient can better cooperate with the shoulders and neck when wearing it. At the same time, the support tube in the heating component is in the shape of a bamboo joint, which cooperates with the triple-helix heat pipe to make the entire pad have good pressure resistance, ensuring that the patient can still work stably when lying flat, thereby extending the service life of the entire pad.

[0020] By setting a swing plate and a fixed plate, during the process of fixing the pad, the medical staff first passes one end of the fixing belt through the slot provided in the outer wall of the circular shell, and continues to pull the fixing belt. When the fixing belt is pulled until the storage bag in the cold compress area is close to the wound on the patient's neck, the medical staff pulls the insertion rod to pull it out of the insertion hole to release the restriction on the pulling rod. At this time, the first spring in the movable groove in a compressed state will deform rapidly to push the rotating seat toward the first gear. At this time, the guide wheel will also move together with the movement of the rotating seat. The movement of the guide wheel can squeeze the fixing belt in the circular shell until the rack on one side of the fixing belt is pressed against the circumferential outer wall of the first gear. At this time, if the medical staff continues to pull the fixing belt, the rack on one side of the fixing belt will mesh with the first gear and drive it to rotate. The rotation of the first gear can drive the second rotating shaft to rotate. During the rotation of the second rotating shaft, the second gear can be driven to rotate together. At this time, the second gear will drive the gear ring plate that is meshed with it to make a circular motion. As the gear ring plate rotates, the first rotating shaft at its center can be driven to rotate. The rotation of the first rotating shaft can drive the swing plate to make a circular motion. When the swing plate rotates to one side of the fixed plate, the swing plate will be blocked by the fixed plate and cannot rotate. At this time, the set maximum binding force is reached, avoiding the situation where excessive force is used to cause secondary injury to the patient's neck.

[0021] By setting a locking assembly, during the contact between the swing plate and the fixed plate, the arc column set on one side of the swing plate will pass through the positioning hole and exert a certain thrust on the first baffle plate. When the first baffle plate is subjected to the thrust, it will drive the vertical plate to move horizontally as a whole. At this time, the first baffle plate will gradually disengage from the supporting groove until it moves to just above the through groove. At this time, the second spring in a compressed state will instantly recover its deformation and drive the telescopic rod to extend. With the instantaneous extension of the telescopic rod, the horizontal plate and the clamping plate can be driven to drop rapidly, so that the fixing belt can be pressed into the clamping groove, thereby achieving locking and fixing of the fixing belt, and preventing the patient from loosening and falling off when wearing the device.

[0045] like Figures 1 to 13As shown, an embodiment of the present invention provides a hot and cold compress device for the shoulder and neck after thyroid surgery, comprising a pad 1, a controller 9 and a connector 10, wherein the pad 1 is provided with a heating area 6 for hot compressing the shoulder and neck and a cold compress area 5 for cooling the wound; the pad 1 comprises a breathable layer 1001, a sponge layer 1002, a graphene thermal insulation layer 1003, a heating component and a fire retardant layer 1005, and the breathable layer 1001, the sponge layer 1002, the graphene thermal insulation layer 1003, the heating component and the fire retardant layer 1005 are fixedly connected in sequence from top to bottom; a locking component for ensuring that the cold compress area 5 is stably applied to the wound is provided on one side of the pad 1; bristle pads 7 and fluff pads 11 are distributed on both sides of the pad 1, and the bristle pads 7 and the fluff pads 11 are bonded to each other; a firing component is provided on one side of the pad 1, and power can be provided to the locking component through the firing component.

[0046] like Figure 3 and Figure 4 As shown, the heating assembly includes a heat pipe 1004 arranged inside the pad 1, and the heat pipe 1004 is in a triple-helix shape. Due to the unique triple-helix shape and the mutually intertwined manner of the heat pipe 1004, the external force can be evenly dispersed in multiple directions, so that it has high strength and bending resistance, ensuring that the patient can better cooperate with the shoulder and neck when wearing it. A graphene heating layer 1006 is arranged inside the heat pipe 1004, and the circumferential outer wall of the graphene heating layer 1006 is closely attached to the circumferential inner wall of the heat pipe 1004. A support tube 1007 for reinforcing the graphene heating layer 1006 is arranged inside the heat-conducting tube 1004. The circumferential outer wall of the support tube 1007 contacts the circumferential inner wall of the graphene heating layer 1006. The cross-section of the support tube 1007 is in the shape of a bamboo joint. Since the support tube 1007 in the heating assembly is in the shape of a bamboo joint, it cooperates with the triple-helical heat-conducting tube 1004, so that the entire pad 1 has good pressure resistance, ensuring that it can still work stably when the patient lies flat, thereby extending the service life of the entire pad 1.

[0047] A storage bag 4 is provided on one side of the cold compress area 5, and the storage bag 4 is fixedly connected to the outer wall of one side of the pad 1. Medicines and cold compresses can be placed in the storage bag 4 to reduce bleeding, eliminate edema, and facilitate rapid recovery of the wound.

[0048] like Figures 5 to 13As shown, the locking assembly includes a fixing belt 2 fixedly connected to one side of the pad 1, a rack 3 is provided on one side of the fixing belt 2, a round shell 8 is fixedly connected to one side of the pad 1, a slot 13 is provided on the circumferential outer wall of the round shell 8, the width of the slot 13 is greater than the width of the fixing belt 2, the height of the slot 13 is the same as the thickness of the fixing belt 2, a locking seat 50 is fixedly connected to the circumferential inner wall of the round shell 8, and a compression groove 51 is provided on the top of the locking seat 50 and is equidistantly distributed, and the cross section of the compression groove 51 is V-shaped. The locking seat 50 is in the shape of a letter " ". A horizontal plate 46 is arranged on the top of the locking seat 50. A clamping plate 49 is fixedly connected to the bottom outer wall of the horizontal plate 46. The clamping plate 49 is located directly above the clamping groove 51. A vertical plate 20 is fixedly connected to the top outer wall of the horizontal plate 46. A first baffle plate 21 is fixedly connected to one side of the vertical plate 20. A through groove 22 is provided on the top outer wall of the circular shell 8. The vertical plate 20 passes through the inside of the through groove 22. A supporting groove 43 is provided on the top outer wall of the circular shell 8. The supporting groove 43 is used to provide support force for the first baffle plate 21.

[0049] During the contact between the swing plate 17 and the fixed plate 18, the arc column 24 arranged on one side of the swing plate 17 will pass through the positioning hole 19 and apply a certain thrust to the first baffle plate 21. When the first baffle plate 21 is subjected to the thrust, it will drive the vertical plate 20 to move horizontally as a whole. At this time, the first baffle plate 21 will gradually disengage from the support groove 43 until it moves to just above the through groove 22. At this time, the second spring 45 in a compressed state will instantly recover its deformation and drive the telescopic rod 23 to extend. With the instantaneous extension of the telescopic rod 23, the cross plate 46 and the clamping plate 49 can be driven to drop rapidly, so that the fixing belt 2 can be pressed into the clamping groove 51, thereby realizing the locking and fixation of the fixing belt 2. Moreover, a plurality of clamping grooves 51 are provided, which can effectively ensure the locking strength of the fixing belt 2, thereby preventing the patient from loosening and falling off when wearing the device.

[0050] like Fig.12 As shown, a slide groove 47 is provided on the top outer wall of the horizontal plate 46, and a slide rod 48 is slidably connected inside the slide groove 47.

The circumferential outer wall of the telescopic rod 23 is sleeved with a second spring 45. The telescopic rod 23 is fixedly connected to the top outer wall of the circular shell 8. The sliding of the slide rod 48 in the slide groove 47 can ensure that the telescopic rod 23 can stably cooperate with the second spring 45 for lifting and lowering.

[0051] like Figures 8 to 11As shown, the firing assembly includes a second rotating shaft 32 rotatably connected to the circumferential inner wall of the circular shell 8, the circumferential outer wall of the second rotating shaft 32 is fixedly connected to the first gear 30, the first gear 30 is meshed with the rack 3, the circumferential outer wall of the second rotating shaft 32 is fixedly connected to the second gear 31, the circumferential outer wall of the second gear 31 is meshed with a gear ring plate 33, the circumferential outer wall of the circular shell 8 is fixedly connected to the annular shell 12, the first gear 30 is partially located inside the annular shell 12, the circumferential inner wall of the gear ring plate 33 is fixedly connected to the first rotating shaft 16, and the first rotating shaft 1 6 is fixedly connected to a rotating block 15 on its circumferential outer wall, a swing plate 17 is fixedly connected to the circumferential outer wall of the rotating block 15, an arc column 24 is fixedly connected to one side outer wall of the swing plate 17, the top outer wall of the circular shell 8 is fixedly connected to the top ring plate 14, the circumferential inner wall of the top ring plate 14 is fixedly connected to the fixing plate 18, a positioning hole 19 is provided on one side outer wall of the fixing plate 18, the positioning hole 19 cooperates with the arc column 24, the medical staff continues to pull the fixing belt 2, and the rack 3 on one side of the fixing belt 2 will mesh with the first gear 30 and drive it to rotate.

[0052] The rotation of the first gear 30 can drive the second shaft 32 to rotate. During the rotation of the second shaft 32, the second gear 31 can be driven to rotate together. At this time, the second gear 31 will drive the gear ring plate 33 meshing with it to make a circular motion. As the gear ring plate 33 rotates, the first shaft 16 at the center thereof can be driven to rotate. The rotation of the first shaft 16 can drive the swing plate 17 to make a circular motion. When the swing plate 17 rotates to one side of the fixed plate 18, the swing plate 17 will be blocked by the fixed plate 18 and cannot rotate. At this time, the set maximum binding force is reached, thereby avoiding the situation where excessive force causes secondary injury to the patient's neck.

[0053] The circumferential inner wall of the round shell 8 is fixedly connected with a fixed frame 41, and movable grooves 36 are provided on both sides of the fixed frame 41. A first spring 38 is fixedly connected to the inner wall of one side of the movable groove 36, and a slide plate 39 is fixedly connected to one end of the first spring 38. The slide plate 39 is slidably connected to the movable groove 36. A guide cylinder 34 is provided in the middle of the fixed frame 41, and rotating rods are fixedly connected to both ends of the guide cylinder 34. One end of the rotating rod is rotatably connected to a rotating seat 40. The rotating seat 40 is located on one side of the movable groove 36, and an outer wall of one side of the slide plate 39 is connected to the rotating seat 4 0, as the medical staff pulls the insertion rod 29, it is pulled out of the insertion hole 35 to release the restriction on the pulling rod 27. At this time, the first spring 38 in the movable groove 36 in a compressed state will deform rapidly to push the rotating seat 40 toward the first gear 30. At this time, the guide wheel will also move with the movement of the rotating seat 40. The movement of the guide wheel can squeeze the fixing belt 2 in the circular shell 8 until the rack 3 on one side of the fixing belt 2 is pressed against the circumferential outer wall of the first gear 30.

[0054] like Figure 7 and Fig. 9 As shown, a pull-out rod 27 is fixedly connected to the bottom outer wall of a rotating seat 40, and the cross-section of the pull-out rod 27 is L-shaped. A pull-out groove 28 is provided on the circumferential inner wall of the round shell 8, and one end of the pull-out rod 27 passes through the inside of the pull-out groove 28. A socket 35 is provided on the top outer wall of the pull-out rod 27, and a connecting block 26 is fixedly connected to the circumferential outer wall of the round shell 8. A plug rod 29 is provided on the top of the connecting block 26, and one end of the plug rod 29 is inserted into the inside of the socket 35. The top of the plug rod 29 is fixedly connected to the handle 25. When the fixing belt 2 is pulled until the storage bag 4 of the cold compress area 5 is close to the wound on the patient's neck, the medical staff pulls the plug rod 29 to remove it from the socket 35 to release the restriction on the pull-out rod 27.

[0055] The bottom outer wall of the pulling rod 27 is fixedly connected with a second baffle 37 , and one side outer wall of the second baffle 37 contacts the circumferential inner wall of the round shell 8 . The second baffle 37 can prevent the pulling rod 27 from being pulled out of the round shell 8 as a whole.

[0056] like Fig.10 and Fig.11 As shown, the top outer wall of the guide cylinder 34 is rotatably connected to a connecting rod 42, and the end of the connecting rod 42 away from the guide cylinder 34 is rotatably connected to a blocking plate 44, and the end of the blocking plate 44 away from the connecting rod 42 is rotatably connected to the circumferential inner wall of the circular shell 8. The blocking plate 44 can prevent the rack 3 on one side of the fixing belt 2 from meshing with the first gear 30 during the initial insertion of the fixing belt 2 into the circular shell 8.

[0057] The workflow of the technical solution provided by the present invention is as follows:

[0058] When in use, the medical staff first adds the medicine and cold compress into the storage bag 4, and then ties the pad 1 to the patient's shoulder and neck. During the process of fixing the pad 1, the medical staff first passes one end of the fixing belt 2 through the slot 13 opened on the outer wall of the round shell 8, and continues to pull the fixing belt 2. When the fixing belt 2 is pulled to the storage bag 4 in the cold compress area 5 and is close to the wound on the patient's neck, the medical staff pulls the insertion rod 29 and pulls it out of the socket 35 to release the restriction on the pulling rod 27. At this time, the first spring 38 in the movable groove 36 in a compressed state will quickly deform and push the rotating seat 40 in the direction close to the first gear 30. At this time, the guide wheel will also move together with the movement of the rotating seat 40. The movement of the guide wheel can squeeze the fixing belt 2 in the round shell 8 until the rack 3 on one side of the fixing belt 2 is pressed against the first gear.

[0059] At the same time, in the process of the swing plate 17 contacting the fixed plate 18, the arc column 24 arranged on one side of the swing plate 17 will pass through the positioning hole 19 and apply a certain thrust to the first baffle plate 21. When the first baffle plate 21 is subjected to the thrust, it will drive the vertical plate 20 to move horizontally as a whole. At this time, the first baffle plate 21 will gradually disengage from the support groove 43 until it moves to just above the through groove 22. At this time, the second spring 45 in the compressed state will instantly recover its deformation and drive the telescopic rod 23 to extend. With the instantaneous extension of the telescopic rod 23, the cross plate 46 and the clamping plate 49 can be driven to drop rapidly, so that the fixing belt 2 can be pressed into the clamping groove 51, thereby realizing the locking and fixation of the fixing belt 2. Moreover, a plurality of clamping grooves 51 are provided, which can effectively ensure the locking strength of the fixing belt 2, thereby avoiding the loosening and falling off of the patient when wearing the device.
