Abstract
Description
Technical Field
[0001] This invention relates to the field of heating device technology, specifically to an adjustable, uniform heating device for the extremities. Background Technology
[0002] Shock is a syndrome caused by a sharp decrease in effective circulating blood volume and a widespread, sustained, and significant reduction in tissue blood perfusion after the body is attacked by a strong pathogenic factor, resulting in poor systemic microcirculation and severe dysfunction of vital organs. At this time, the body loses its compensatory mechanisms, tissues experience ischemia and hypoxia, and neurohumoral factors become imbalanced. Its main characteristics are: insufficient microcirculatory perfusion in vital organs and tissues, metabolic disorders, and dysfunction of various systems throughout the body. In short, shock is the body's response to a reduction in effective circulating blood volume; it is a pathological process of metabolic and cellular damage caused by insufficient tissue perfusion. In cold winters, when administering intravenous infusions via the hand or foot, disposable heating bags are used to heat the infusion tubing, warming the medication flowing through it and preventing the cold medication from being directly administered to the patient and causing discomfort.
[0003] There are shortcomings in the current method of heating the patient's hands:
[0004] 1. When heating the patient's hands, although the infusion tube is heated by a heating bag, the heat from the heating bag dissipates quickly in winter. In addition, the heating bag can only heat a local area and cannot heat a large area. As a result, the patient's extremities cannot be effectively relieved of cold, nor can they effectively improve blood circulation. Furthermore, the heat level of the heating bag cannot be adjusted, which may easily burn the patient's skin.
[0005] 2. At the same time, the extremities are the furthest from the heart, so the blood circulation rate in the extremities is slower than in other parts of the body. This requires medical staff to perform manual massage on the shocked patients, which increases the workload of medical staff.
[0006] 3. The disadvantages of using a heating bag to heat the infusion tubing during intravenous infusion are that the heating bag outputs insufficient heat and the duration of heat is not long enough to heat the infusion tubing for an extended period. Furthermore, it is inconvenient to secure the infusion tubing to the heating bag, which can lead to separation between the heating bag and the infusion tubing. Summary of the Invention
[0007] The purpose of this invention is to provide an adjustable, uniform heating device for limb extremities to solve the related problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution: an adjustable, uniformly heated limb extremity device, comprising a heating chamber, a support ring disposed at the middle position of one side of the heating chamber, a placement pad disposed on the inner side of the support ring, drive motors disposed at the top and bottom of the heating chamber on the side away from the support ring, gears disposed at the output ends of the two sets of drive motors, a through hole being formed at the middle position of the heating chamber on the side near the drive motors, and an annular groove being formed inside the heating chamber on the side near the drive motors, with a massage mechanism slidably disposed inside the annular groove.

Metal heating blocks are located at both ends of the interior of the placement box. An infusion tube groove is located on the side where the two sets of metal heating blocks are interlocked. An air vent is located at one end of the back of the placement box.
[0009] Preferably, the adjusting mechanism includes a swing rod, a slip ring, a fixed rod, a rotating plate, a first through groove, and a swing groove. The swing groove is provided in two sets on both sides of the top inside the heating box. Swing rods are slidably arranged inside the two sets of swing grooves. A rotating plate is provided at the bottom of the two sets of swing rods. Multiple sets of first through grooves are evenly opened inside the rotating plate.

Annular racks are provided on the outer side of the four sets of connecting rods.
[0011] Preferably, the annular rack is located between two sets of gears, and the two sets of gears mesh with the annular rack.
[0012] Preferably, the base plate of the swing arm extends into the interior of the mounting frame, and the rotating plate is located inside the mounting frame.
[0013] Preferably, the bottom of the mounting frame is provided with annular limiting grooves on both sides, and the inner side of the rotating plate is provided with limiting slip rings on both sides, and the limiting slip rings slide inside the annular limiting grooves.
[0014] Preferably, a rubber ring is provided on the inner side of the fixing hole, and an anti-slip texture is provided on the outer side of the fixing rod. The bottom of the fixing rod extends into the interior of the fixing hole and is adapted to each other.
[0015] Preferably, the movable groove has limit grooves at both ends, and the support rod has limit blocks on one side at both ends, with the limit blocks located inside the limit groove.

[0017] Preferably, the outer side of the heating box is provided with a heat insulation layer, and the inner side of the mounting frame is provided with a heat insulation layer.
[0018] Compared with the prior art, the present invention provides an adjustable, uniform heating device for limb extremities, which has the following beneficial effects:
[0019] 1. This invention uses multiple sets of heating lamps to heat the extremities of a patient. Since the heating lamps do not directly contact the patient's skin, they will not cause burns. Furthermore, the interior and exterior of the heating chamber are interconnected, preventing excessive sweating and discomfort for the patient. Simultaneously, the overlapping area between the first and second through slots can be adjusted by rotating the rotating plate and the mounting frame, thereby adjusting the area illuminated by the heating lamps. This allows for flexible temperature control within the heating chamber, ensuring uniform heating of the patient's extremities, improving blood circulation, and ensuring rapid temperature recovery.
[0020] 2. This invention utilizes multiple sets of massage rollers to contact and rotate with the patient's limb extremities. The rotating massage rollers can squeeze and massage the patient's limb extremities, promoting blood circulation. The increased blood circulation allows the temperature of the patient's limb extremities to recover quickly. At the same time, the distance between the two sets of support rods can be adjusted, allowing the massage rollers to massage limb extremities of different thicknesses, flexibly adapting to patients of different body types. The massage of multiple sets of massage rollers can greatly reduce the workload of medical staff and significantly improve work efficiency.
[0021] 3. This invention utilizes the combination of a flow-guiding fan and a placement box to evenly distribute the infusion tube inside the flow-guiding fan and ensure full contact with the metal heating block. When the device heats the patient's limb, the flow-guiding fan delivers heat to the inside of the placement box, simultaneously heating the metal heating block and the infusion tube. This not only reduces the instability of heat output but also secures the infusion tube, preventing accidental pulling. Attached Figure Description

The connecting rod 301 is provided with four sets of sliding grooves located inside the annular grooves 7. A turntable 303 is provided on one side of the four sets of connecting rods 301. Movable grooves 302 are provided at the top and bottom of the turntable 303. Support rods 305 are slidably provided inside the two sets of movable grooves 302. Multiple sets of massage rollers 307 are evenly provided on the outer side of the two sets of support rods 305.

An annular rack 304 is provided on the outer side of the four sets of connecting rods 301. This mechanism can massage the extremities of patients, greatly reducing the workload of medical staff.
[0035] As a preferred embodiment, the annular rack 304 is located between the two sets of gears 5, and the two sets of gears 5 mesh with the annular rack 304, so that the two sets of gears 5 can drive the multiple sets of massage rollers 307 to rotate.
[0036] As a preferred embodiment, the bottom plate of the swing rod 201 extends into the interior of the mounting frame 9, and the rotating plate 204 is located inside the mounting frame 9, so that the rotating plate 204 and the mounting frame 9 are in seamless contact.
[0037] As a preferred embodiment, the bottom of the mounting frame 9 is provided with annular limiting grooves on both sides, and the inner side of the rotating plate 204 is provided with limiting slip rings on both sides. The limiting slip rings slide inside the annular limiting grooves, making the rotation of the rotating plate 204 more stable.
[0038] As a preferred embodiment, a rubber ring is provided on the inner side of the fixing hole 12, and anti-slip texture is provided on the outer side of the fixing rod 203. The bottom of the fixing rod 203 extends into the interior of the fixing hole 12 and is adapted to each other, so that the fixing rod 203 is inserted into the interior of the fixing hole 12 more tightly.
[0039] As a preferred embodiment, the two ends of the movable groove 302 are provided with limiting grooves, and one side of the two ends of the support rod 305 is provided with limiting blocks, and the limiting blocks are located inside the limiting groove.
[0040] As a preferred embodiment, the massage roller 307 has multiple raised dots on its outer side, and the raised dots are made of rubber.
[0041] As a preferred embodiment, the heating box 1 is provided with a heat insulation layer on the outside and the mounting frame 9 is provided with a heat insulation layer on the inside to prevent accidental burns caused by excessively high temperature on the outside of the heating box 1.
[0042] Example 1, such as Figure 1 and Figure 6As shown, when adjusting the distance between the two sets of support rods 305, a hand can be inserted into the heating chamber 1 through the through hole 6 to rotate the bidirectional threaded rod 306. Under the action of the thread, the bidirectional threaded rod 306 will drive the two sets of support rods 305 to slide inside the movable groove 302, causing the massage rollers 307 to move in position. When the massage rollers 307 contact the patient's limb ends, the bidirectional threaded rod 306 is rotated slightly to make the massage rollers 307 exert a slight squeezing force on the patient's limb ends, so that the massage rollers 307 can massage the patient's limb ends well. At this time, the two sets of drive motors 8 are turned on to drive the gears 5 to rotate. The two sets of gears 5 drive the turntable 303 to rotate through the connecting rod 301. The turntable 303 drives the support rods 305 to rotate through the movable groove 302, so that the multiple sets of massage rollers 307 massage around the patient's limb ends, accelerate blood circulation, and accelerate the recovery of the patient's limb end temperature.
[0043] Example 2, as Figure 2-5 As shown, when the heating lamp 4 is turned on to heat the patient's limb, and the temperature inside the heating chamber 1 needs to be adjusted, the slip ring 202 can be lifted upwards, causing the two sets of fixing rods 203 to disengage from the inside of the fixing hole 12, thus releasing the fixation of the slip ring 202. At this time, the swing rod 201 can swing inside the swing groove 206. The two sets of swing rods 201 drive the rotating plate 204 to rotate inside the mounting frame 9, causing the first through groove 205 to move. The overlapping area between the first through groove 205 and the second through groove 13 adjusts the area of the light source. The larger the area of the light source irradiated by the heating lamp 4 on the patient's limb, the higher the temperature. Then, the fixing rod 203 is inserted into the corresponding fixing hole 12 to fix the slip ring 202 and the swing rod 201.
[0044] Working principle: First, the patient's limb end is inserted into the heating chamber 1 through the support ring 11. At this time, the two-way threaded rod 306 is rotated, and the two sets of support rods 305 are driven to move closer to each other under the action of the thread, so that the massage roller 307 comes into contact with the patient's limb end. At this time, the drive motor 8 is turned on, and the drive motor 8 drives the ring rack 304 to rotate through the gear 5. The ring rack 304 drives the turntable 303 to rotate through the four sets of connecting rods 301. Thus, the support rods 305 and the massage roller 307 rotate around the patient's limb end and massage to promote blood circulation. At the same time, the heating lamp 4 is turned on. The heating lamp 4 shines light on the patient's limb end through the first through groove 205 and the second through groove 13. Since the rotating plate 204 and the mounting frame 9 can rotate relative to each other, the overlapping area between the first through groove 205 and the second through groove 13 can be adjusted. The larger the area, the more light is irradiated and the higher the temperature will be. It is necessary to flexibly adjust the area of the light source according to the actual situation.
[0045] When heating the infusion tube, the placement box 18 is unfolded via the hinge shaft. At this time, the infusion tube is placed inside the flow fan 14. After the arrangement is completed, the placement box 18 is closed and fixed, so that the two sets of metal heating blocks 15 come into contact with each other and squeeze the infusion tube. At this time, when heating the patient's limb end, the heat inside the flow fan 14 is transferred to the inside of the placement box 18 to heat the metal heating blocks 15 and the infusion tube, so that the patient will not feel the coldness of the liquid during the infusion. At this time, the massage mechanism 3 will not work.
[0046] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
