Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and in particular to a portable warming device for post-microsurgery rehabilitation. Background Art

[0002] In the field of microsurgery, postoperative care plays a key role in patient recovery. Taking the guard frame heating lamp used by the Hand Surgery Department of Jishuitan Hospital as a typical example, this type of heating lamp is widely used in scenarios such as limb (finger) replantation, finger reconstruction, various arterial injury surgery, and various free flaps, bone flaps, and vascularized composite tissue flaps. Its core function is to create a suitable local temperature environment, usually maintained at a stable temperature of 20-25°C. This improves local blood circulation, helps quickly reduce swelling, reduces muscle tension and relieves muscle tension, ultimately achieving the purpose of effectively relieving pain. Its structure consists of a heating lamp base, an adjustable support rod, a lamp holder support rod, a snake skin threaded tube lampshade, a lamp holder, a 60W bulb, a power switch, a power cord, a power plug, and a heating lampshade.

[0003] However, the current heating lamps used in clinical practice have exposed many defects that are difficult to ignore. For patients who have undergone skin flap transplantation and finger (limb) replantation surgery, they need to continue to use heating lamps to keep warm after surgery to promote wound healing and avoid low temperature environments stimulating small blood vessels to spasm, which has a negative impact on postoperative recovery. In the actual operation process, medical staff must always monitor the temperature changes on the flap surface. Once the flap surface temperature deviates from the normal range, whether it is too high or too low, medical staff need to manually adjust the height of the heating lamp to ensure that the flap surface temperature is always in the appropriate range. The method of relying entirely on manual control greatly increases the daily workload of medical staff, and they also need to pay attention to the status of the heating lamp at all times during busy work. In addition, due to a certain lag in manual operation, it is very likely that the patient's skin will be burned due to untimely adjustment, or the skin recovery effect will be difficult to achieve the expected effect due to unsuitable temperature for a long time, which seriously hinders the patient's recovery process.

[0025] Example 1 See also Figure 1-7 A portable warming device for post-microsurgery rehabilitation comprises a forearm warming mechanism 1 and an upper arm warming mechanism 2, wherein the forearm warming mechanism 1 is adjustably connected to the upper arm warming mechanism 2 via a detachable connecting mechanism 3; The forearm warming mechanism 1 and the upper arm warming mechanism 2 each include an outer shell 100, a turbine frame 110 with a notch mounted on one end of the outer shell 100, a guide frame 120 mounted on the other end of the inner shell 100, and a first heating structure 200 mounted between the turbine frame 110 and the guide frame 120, which is positioned inside the outer shell 100 and can be adjusted in multiple directions and can simultaneously maintain a constant temperature for the severed limb skin flap. The first heating structure 200 integrates a monitoring mechanism 210 for taking photos of the severed limb skin flap's growth status and a temperature monitoring mechanism 220. One side of the outer shell 100 is provided with an opening 130 for inserting and removing the arm. The opening 130 is hinged with a transparent cover 131 through a damping hinge. Both ends of the inner side of the outer shell 100 are fixedly installed with inflatable airbags 140 with a C-shaped appearance for covering the patient's limbs. A support box 300 is fixedly installed at the bottom of the outer shell 100. A driving mechanism 310 for driving the turbine frame 110 is installed inside the support box 300. A control circuit board is also installed inside the driving mechanism 310. The control circuit board is electrically connected to a controller 400 with a touch display and control buttons through wired or wireless means.

[0026] Specifically, in clinical use scenarios, when a patient needs rehabilitation and warmth, the device can be placed on a hospital bed due to its good portability. The device can be fixed to the bed rails by straps or other fixings and placed on both sides of the bed, which not only greatly reduces the workload of medical staff and frees them from tedious manual adjustment work, but also allows the medical staff to adjust the forearm warming mechanism 1 and the upper arm warming mechanism 2 through the detachable connecting mechanism 3 according to the specific conditions of the patient's arm, so that the distance between the forearm warming mechanism 1 and the upper arm warming mechanism 2 can be adapted to the patient's arm. Of course, according to the patient's treatment needs, the forearm warming mechanism 1 and the upper arm warming mechanism 2 can also be used separately. Then, a soft support material such as a support cushion can be placed inside the outer shell 100, and the patient's arm is placed into the outer shell 100 through the opening 130. Then, an electric air pump or a manual air pump is used to inflate the inflatable airbag 140 to cover the patient's limb, providing a certain degree of support and fixation. Then, the cover 131 is closed, so that the interior of the outer shell 100 can maintain a relatively sealed space. The medical staff then operates the controller 400 with a touch display and control buttons. The control circuit board transmits the signal to the drive mechanism 310, which drives the turbine frame 110. Since the first heating structure 200 is installed between the turbine frame 110 and the guide frame 120, the rotation of the turbine frame 110 can drive the first heating structure 200 to adjust its position in multiple directions, thereby achieving precise constant temperature warming of the severed limb skin flap. At the same time, the monitoring mechanism 210 and the temperature monitoring mechanism 220 are integrated into the first heating structure 200. The monitoring mechanism 210 takes pictures of the growth status of the skin flap of the severed limb, the temperature monitoring mechanism 220 detects the temperature in real time, and the data is transmitted to the control circuit board, which is then presented on the touch display of the controller 400. At the same time, the image of the skin flap of the severed limb taken can also be displayed through the touch display, which is convenient for medical staff to understand the condition of the skin flap of the patient's severed limb. The transparent cover 131 is hinged at the opening 130 by a damping hinge, and medical staff can open it at any time to observe the skin flap, providing a more intuitive basis for treatment and more convenient to understand the growth status of the skin flap of the patient's severed limb.

[0027] In this embodiment: the connecting mechanism 3 includes a plurality of fixing straps 320 respectively fixedly mounted on one end of the forearm warming mechanism 1 and the upper arm warming mechanism 2, and the two oppositely positioned fixing straps 320 are connected by a detachable Japanese buckle 330.

[0028] Specifically, medical staff can connect the two opposite fixing straps 320 through the Japanese-shaped buckle 330 according to needs. For patients with thinner arms, the fixing strap 320 can be tightened through the Japanese-shaped buckle 330 to make the forearm warming mechanism 1 and the upper arm warming mechanism 2 fit closely to the patient's arm to ensure the warming effect; if the patient's arm is thicker or the injured part has special requirements, the length of the fixing strap 320 can be appropriately adjusted through the Japanese-shaped buckle 330 to make the two warming mechanisms adapt to the patient's arm to ensure comfort and effectiveness of use. At the same time, it is also convenient to flexibly adjust the connection status between the two warming mechanisms according to the different stages of the patient's recovery process.

[0029] In this embodiment: the shell wall of the outer shell 100 is provided with an interlayer 101, the inner side of the turbine frame 110 is provided with a first arc-shaped guide groove 111, the first arc-shaped guide groove 111 and the inner side of the interlayer 101 are fixed with an arc-shaped guide strip for guiding and sliding connection, the interlayer 101 is provided with openings 102 at both ends of the turbine frame 110, and the end of the turbine frame 110 can pass through the opening 102 into the opening 130, and the inner side of the outer shell 100 is also provided with a slot 103, and an exhaust fan 104 is installed on the outside of the outer shell 100, and the exhaust fan 104 is connected to the interior of the outer shell 100.

[0030] Specifically, when the device is working, the driving mechanism 310 drives the turbine frame 110 to rotate. Due to the guiding effect of the first arc-shaped guide groove 111 and the arc-shaped guide bar, the turbine frame 110 can rotate stably along a specific trajectory. When the turbine frame 110 rotates, its end can pass through the opening 102 and enter the opening 130, so that the first heating structure 200 can be closer to the patient's amputated limb skin flap area to achieve precise warming. While the patient is using the device for warming, if the internal temperature is too high, the control circuit board will control the exhaust fan 104 to start after receiving the signal from the temperature monitoring mechanism 220, and discharge the internal hot air to keep the internal temperature constant, providing the patient with a suitable warming environment.

[0031] In this embodiment: the warm first heating structure 200 also includes an "I"-shaped mounting frame 230, and a belt drive mechanism 231 is fixedly installed in the middle of the mounting frame 230. The belt drive mechanism 231 includes a first drive motor 232 fixedly installed at one end of the middle of the mounting frame 230, and the output shaft of the first drive motor 232 is connected to a driven pulley 233 through a driving pulley and a belt transmission. The driven pulley 233 is installed at the other end of the middle of the mounting frame 230, and a guide rod 234 is fixedly installed on the top and bottom of the mounting frame 230. One end of the guide rod 234 is detachably connected to the inner side of the turbine frame 110, and the other end of the guide rod 234 is slidingly connected to the second arc-shaped guide groove 121 provided in the guide frame 120. The outer side of the two guide rods 234 is slidingly connected to a mounting seat 235. The back side of the mounting seat 235 is connected to the belt through a belt clip, and the front side of the mounting seat 235 is installed with a second heating mechanism 250 through a spacing adjustment mechanism 240.

[0032] Specifically, the monitoring mechanism 210 takes pictures of the growth status of the severed limb skin flap and analyzes the position information, and then transmits the data to the control circuit board. The control circuit board sends instructions to the first drive motor 232, and the output shaft of the first drive motor 232 rotates, and is connected to the driven pulley 233 through the active pulley and belt transmission, thereby driving the mounting frame 230 to move. The two guide rods 234 provided can guide the sliding of the mounting seat 235, and then cooperate with the rotation of the turbine frame 110. The guide rod 234 slides along the second arc-shaped guide groove 121, thereby driving the second heating mechanism 250 installed on the front of the mounting seat 235 through the spacing adjustment mechanism 240 to move to the appropriate position in multiple dimensions, thereby realizing precise heating of different positions of the severed limb skin flap.

[0033] In this embodiment: the spacing adjustment mechanism 240 includes a mounting box 241 fixedly mounted on the front of the mounting seat 235, both sides of the mounting box 241 are rotatably connected to a U-shaped seat 243 via a rotating shaft 242, and both ends of the interior of the mounting box 241 are fixedly mounted with a reduction motor 244, and the output shaft of the reduction motor 244 is fixedly connected to the corresponding rotating shaft 242 via a coupling.

[0034] Specifically, by analyzing the images captured by the monitoring mechanism 210, an instruction can be sent to the control circuit board through the controller 400. The control circuit board controls the reduction motors 244 at both ends of the installation box 241 to start, and the reduction motor 244 rotates to drive the rotating shaft 242 to rotate. The U-shaped seat 243 will change its angle as the rotating shaft 242 rotates, thereby adjusting the distance between the second heating mechanism 250 fixedly installed on the front of the U-shaped seat 243 and the skin flap to ensure the accuracy of the heating effect; and when medical staff observe through the monitoring mechanism 210 or the transparent cover 131 that a certain part of the skin flap needs closer heating, it can also be adjusted through the distance adjustment mechanism 240 to facilitate medical staff to observe the growth of the skin flap.

[0035] In this embodiment: the second heating mechanism 250 includes a metal shell 251 fixedly mounted on the front of the U-shaped seat 243. The metal shell 251 passes through the slot 103 and is placed on the inner side of the outer shell 100. Two independent cavities 252 are provided inside the metal shell 251. One of the cavities 252 is installed with a plurality of heating wires 253 wound in a circular shape, and the cavity 252 is also installed with a plurality of high-temperature resistant lamps 254 that can emit red light.

[0036] Specifically, when the patient is undergoing rehabilitation and warming, the control circuit board controls the operation of the heating wire 253 and the high-temperature resistant lamp tube 254 based on the temperature information fed back by the temperature monitoring mechanism 220 and the temperature value set by the medical staff on the controller 400. When the temperature is lower than the set value, the heating wire 253 starts to heat up, and the high-temperature resistant lamp tube 254 emits red light to generate heat to heat and warm the severed limb skin flap. Since the heating wire 253 is wound in a U-shaped pattern, it can dissipate heat more evenly, improve the heating efficiency and effect, provide a stable temperature environment for the patient's severed limb skin flap, and promote rehabilitation.

[0037] In this embodiment: the monitoring mechanism 210 includes an intelligent pan-tilt head 211 installed inside a cavity 252 and capable of multi-dimensional movement. The base of the intelligent pan-tilt head 211 is equipped with an AI camera 212 with feature recognition. The temperature monitoring mechanism 220 is a plurality of temperature sensors 221 installed on the surface of the base of the intelligent pan-tilt head 211.

[0038] Specifically, when medical staff need to observe the growth of the skin flap of the severed limb, they can send instructions to the control circuit board through the controller 400, and the control circuit board controls the movement of the intelligent pan-tilt head 211. Driven by the intelligent pan-tilt head 211, the AI ​​camera 212 can shoot the skin flap of the severed limb from different angles. The multiple temperature sensors 221 of the temperature monitoring mechanism 220 can detect the temperature of the skin flap surface in real time. The photos of the skin flap growth status taken by the AI ​​camera 212 and the temperature data detected by the temperature sensor 221 will be transmitted to the touch display of the controller 400 through the control circuit board, which is convenient for medical staff to understand the growth and temperature of the patient's severed limb skin flap at any time and adjust the treatment plan in time.

[0039] In this embodiment: the driving mechanism 310 includes a second driving motor 311 fixedly installed inside the support box 300, the output shaft of the second driving motor 311 is connected to a reducer 312 with a self-locking function, the output shaft of the reducer 312 is connected to a worm 313, and the worm 313 is meshed with the turbine teeth on the outside of the turbine frame 110.

[0040] Specifically, when medical staff issues an instruction to adjust the position of the first heating structure 200 through the controller 400, the control circuit board transmits a signal to the second drive motor 311, and the output shaft of the second drive motor 311 rotates, and then cooperates with the reducer 312 and the worm 313 to enable the turbine frame 110 to rotate stably, thereby driving the first heating structure 200 to adjust its position in multiple dimensions, thereby achieving precise warming of the severed limb skin flap. At the same time, due to the self-locking function of the reducer 312, when the first heating structure 200 is adjusted to the appropriate position, it can remain stable and will not change arbitrarily due to external forces or other factors.

[0041] In this embodiment, a metal handle 132 is embedded in the outer bottom of the cover 131 , and a magnetic block 133 is embedded in the bottom of the opening 130 opposite to the handle 132 .

[0042] Specifically, when medical personnel need to observe a patient's amputated limb skin flap, they can easily open cover 131 by gripping handle 132 and utilizing the damping hinge. When cover 131 is closed, magnet 133 and handle 132 attract each other, allowing cover 131 to fit tightly against opening 130, preventing heat loss and maintaining a stable temperature within outer shell 100.

[0043] In this embodiment: the temperature sensor 221 and the controller 400 are electrically connected to the control circuit board, and the control circuit board is electrically connected to the exhaust fan 104, the first drive motor 232, the reduction motor 244, the heating wire 253, the high temperature resistant lamp 254, the smart pan-tilt head 211, the AI ​​camera 212, the smart pan-tilt head 211 and the second drive motor 311.

[0044] Specifically, the temperature sensor 221 detects the heating temperature of the patient's limb in real time and transmits the temperature data to the control circuit board. When the temperature is too high, the control circuit board controls the exhaust fan 104 to start heat dissipation. When the position of the first heating structure 200 needs to be adjusted, the control circuit board controls the first drive motor 232 and the second drive motor 311 to work. When the distance between the second heating mechanism 250 and the skin flap needs to be adjusted, the control circuit board controls the reduction motor 244 to work, etc. Through collaborative control, the intelligent operation of the device is realized, providing patients with efficient and accurate limb rehabilitation and warming services.
