Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a medical heating device. Background Technology

[0002] In the medical field, doctors typically use self-prepared, temperature-controlled rinsing solutions to repeatedly wash patients' bodies before and after surgery. Currently, to maintain the temperature of the rinsing solution, doctors use a medical heating device based on electromagnetic heating. The specific heating process is as follows: electromagnetic induction occurs between the coil and the pipe in the medical heating device, generating eddy currents on the surface of the pipe. These eddy currents generate heat, which heats the pipe. The heated pipe then transfers this heat to the rinsing solution, raising its temperature.

[0003] Compared to medical heating devices that use resistance wires to heat medicines, medical heating devices that use electromagnetic induction to heat medicines are safer in terms of electricity use. However, in related technologies, medical heating devices that use electromagnetic induction to heat medicines have poor high-temperature resistance and are difficult to heat medicines to high temperatures. Utility Model Content

[0004] Therefore, it is necessary to provide a medical heating device to address the problem that current medical heating devices have poor high-temperature resistance and are unable to heat medicines to high temperatures.

[0005] A medical heating device, comprising:

[0006] Heating element;

[0007] A heat-conducting layer is fitted around the outer periphery of the heating tube;

[0008] An electromagnetic induction layer is sleeved on the outer periphery of the thermally conductive layer;

[0009] A heating coil is disposed on the outer periphery of the electromagnetic induction layer for electromagnetic induction heating of the electromagnetic induction layer.

[0010] In one embodiment, the heating element is made of at least one of titanium, 316 stainless steel, and nickel-chromium alloy.

[0011] In one embodiment, the thermally conductive layer is made of at least one of copper and aluminum alloys.

[0012] In one embodiment, the medical heating device includes an insulating layer that is sleeved on the outer periphery of the electromagnetic induction layer, and the heating coil is disposed on the outer periphery of the insulating layer.

[0013] In one embodiment, the heating tube includes a heating tube segment and an installation tube segment, and the heat-conducting layer is sleeved on the outer periphery of the heating tube segment;

[0014] The installation pipe section is located at one end of the heating pipe section along its own axial direction. The central axis of the installation pipe section coincides with the central axis of the heating pipe section, and the installation pipe section and the heating pipe section are interconnected. The outer periphery of the installation pipe section is provided with external threads.

[0015] In one embodiment, the medical heating device includes an adapter, the adapter including two through holes communicating with a liquid-containing chamber;

[0016] The inner wall of the through hole is provided with internal threads, and the mounting pipe section is located in one of the two through holes, and the mounting pipe section is threadedly connected to the corresponding through hole.

[0017] In one embodiment, the heating tube includes two mounting sections, which are respectively located at opposite ends of the heating tube section along its own axial direction;

[0018] The medical heating device includes two adapters, which are correspondingly provided with two mounting pipe sections. Each mounting pipe section is threadedly connected to a corresponding through hole in the corresponding adapter.

[0019] In one embodiment, the medical heating device includes a stirring shaft extending axially along the heating tube section, with a portion of the stirring shaft located within the liquid-containing cavity and another portion located within the mounting tube section;

[0020] The stirring shaft is rotatably connected to the adapter, the stirring shaft is configured to rotate about its own axis, and the outer circumferential surface of the stirring shaft is provided with stirring blades.

[0021] In one embodiment, the stirring blades are arranged in a spiral shape.

[0022] In one embodiment, the liquid-containing cavity is provided with an assembly hole on the side opposite to the mounting pipe section along the axial direction of the heating pipe section, and the central axis of the assembly hole coincides with the central axis of the heating pipe section.

[0023] One end of the stirring shaft is located inside the assembly hole, and the other end of the stirring shaft passes through the installation pipe section.

[0024] In this embodiment, an alternating current is passed through the heating coil, which generates an alternating magnetic field. The alternating magnetic field generates eddy currents in multiple regions of the electromagnetic induction layer. Each eddy current generates heat, which is conducted to the heat-conducting layer through the contact surface between the electromagnetic induction layer and the heat-conducting layer. The heat-conducting layer is thermally conductive, and the heat entering the heat-conducting layer is evenly diffused to different regions within the heat-conducting layer, raising the temperature of different regions in the heat-conducting layer to the same level. The increased temperature of the heat-conducting layer heats the heating tube, causing the temperature of the heating tube to rise. The medicine inside the heating tube is heated. Because the temperature is the same in different regions of the heat-conducting layer, the surface of the heating tube in contact with the heat-conducting layer is evenly heated by the heat-conducting layer. The heating tube will not develop cracks due to temperature differences in different regions, and the heating tube can be heated to a higher temperature.

[0025] In summary, the medical heating device in this embodiment improves the high-temperature resistance of the heating tube by wrapping a heat-conducting layer around the outer periphery of the heating tube, allowing the medicine to be heated to a higher temperature. Attached Figure Description

[0044] Please see Figure 1 , Figure 1 The diagram shows a schematic of the structure of a medical heating device according to an embodiment of this application. A medical heating device 1000 provided in an embodiment of this application includes: a heating tube 1100, a heat-conducting layer 1200, an electromagnetic induction layer 1300, and a heating coil 1500. The heat-conducting layer 1200 is sleeved on the outer periphery of the heating tube 1100, the electromagnetic induction layer 1300 is sleeved on the outer periphery of the heat-conducting layer 1200, and the heating coil 1500 is disposed on the outer periphery of the electromagnetic induction layer 1300 for electromagnetic induction heating of the electromagnetic induction layer 1300.

[0045] In this embodiment, an alternating current is passed through the heating coil 1500, which generates an alternating magnetic field. This alternating magnetic field induces eddy currents in multiple regions of the electromagnetic induction layer 1300. Each eddy current generates heat, which is conducted through the contact surface between the electromagnetic induction layer 1300 and the heat-conducting layer 1200. The heat-conducting layer 1200 is thermally conductive, and the heat entering the heat-conducting layer 1200 is evenly diffused to different regions within the heat-conducting layer 1200, thus ensuring the heat-conducting layer 1200 remains thermally conductive. The temperature rises to the same level in different areas of the 200 heat-conducting layer 1200, which in turn heats the heating tube 1100. As the temperature of the heating tube 1100 rises, the medicine inside the heating tube 1100 is heated. Since the temperature is the same in different areas of the heat-conducting layer 1200, the surface of the heating tube 1100 in contact with the heat-conducting layer 1200 is heated evenly by the heat-conducting layer. The heating tube 1100 will not develop cracks due to temperature differences in different areas, and the heating tube 1100 can be heated to a higher temperature.

[0046] In summary, the medical heating device 1000 in this embodiment improves the high temperature resistance of the heating tube 1100 by having a heat-conducting layer 1200 sleeved around the outer periphery of the heating tube 1100, allowing the medicine to be heated to a higher temperature.

[0047] Please continue reading. Figure 1 In some embodiments, the heating element 1100 is made of at least one of titanium, 316 stainless steel and nickel-chromium alloy.

[0048] In this embodiment, the heating tube 1100 is made of at least one of titanium, 316 stainless steel and nickel-chromium alloy. On the one hand, this can improve the corrosion resistance of the heating tube 1100 and prevent the heating tube 1100 from being damaged and leaking due to corrosion by the medicine. On the other hand, it can improve the thermal conductivity of the heating tube 1100, thereby increasing the heating temperature of the heating tube 1100 on the medicine.

[0049] In addition, it should be noted that since the temperature is the same in different areas of the heat-conducting layer 1200, the surface of the heating tube 1100 in contact with the heat-conducting layer 1200 is uniformly heated by the heat-conducting layer. Therefore, the heating tube 1100 will not experience titanium oxidation due to excessively high local temperatures, and the titanium in the heating tube 1100 is protected.

[0051] In this embodiment, by setting the material of the heat-conducting layer 1200 to include at least one of copper and aluminum alloy, the thermal conductivity of the heat-conducting layer 1200 can be improved.

Figure 1 In some embodiments, the medical heating device 1000 includes an insulating layer 1400, which is sleeved on the outer periphery of the electromagnetic induction layer 1300, and a heating coil 1500 is disposed on the outer periphery of the insulating layer 1400.

[0053] In this embodiment, an insulating layer 1400 is sleeved on the outer periphery of the electromagnetic induction layer 1300, and a heating coil 1500 is disposed on the outer periphery of the insulating layer 1400. The insulating layer 1400 is disposed between the electromagnetic induction layer 1300 and the heating coil 1500 to prevent water molecules from adhering to the outer periphery of the electromagnetic induction layer 1300, ensuring the dryness of the electromagnetic induction layer 1300, and preventing the electromagnetic induction layer 1300 from being corroded and oxidized by the external environment.

[0054] Please continue reading. Figure 1 In some embodiments, the heating tube 1100 includes a heating tube segment 1110 and an installation tube segment 1120. The heat-conducting layer 1200 is sleeved on the outer periphery of the heating tube segment 1110. The installation tube segment 1120 is located at one end of the heating tube segment 1110 along its own axial direction. The central axis of the installation tube segment 1120 coincides with the central axis of the heating tube segment 1110, and the installation tube segment 1120 and the heating tube segment 1110 are interconnected. The outer periphery of the installation tube segment 1120 is provided with external threads (not shown in the figure).

[0055] In this embodiment, an alternating current is passed through the heating coil 1500, which generates an alternating magnetic field. The alternating magnetic field generates eddy currents in multiple regions of the electromagnetic induction layer 1300. Each eddy current generates heat, which is conducted to the heat-conducting layer 1200 through the contact surface between the electromagnetic induction layer 1300 and the heat-conducting layer 1200. The heat-conducting layer 1200 is thermally conductive, and the heat entering the heat-conducting layer 1200 is evenly diffused to different regions within the heat-conducting layer 1200, raising the temperature of different regions within the heat-conducting layer 1200 to the same level. The increased temperature of the heat-conducting layer 1200 heats the heating tube section 1110, causing the temperature of the heating tube section 1110 to rise and the medicine inside the heating tube section 1110 to be heated. Since the temperature is the same in different areas of the heat-conducting layer 1200, the surface of the heating tube segment 1110 in contact with the heat-conducting layer 1200 is uniformly heated by the heat-conducting layer. The heating tube segment 1110 will not produce cracks due to different temperatures in different areas, and the heating tube segment 1110 can be heated to a higher temperature.

Figure 1In some embodiments, the medical heating device 1000 includes an adapter 1600, which includes a liquid-containing cavity 1610 and two through holes 1620 communicating with the liquid-containing cavity 1610. The inner wall of the through hole 1620 is provided with an internal thread (not shown in the figure). The mounting tube section 1120 is located in one of the two through holes 1620 and is threadedly connected to the corresponding through hole 1620.

[0057] In this embodiment, the liquid medicine in the heating pipe section 1110 is heated by the heating pipe section 1110, enters the installation pipe section 1120, and enters the liquid-containing cavity 1610 through the installation pipe section 1120, and then leaves the liquid-containing cavity 1610 through the through hole 1620 that is not threadedly connected to the installation pipe section 1120.

[0058] In some embodiments, the central axis of one of the two through holes 1620 intersects with the central axis of the other through hole 1620.

Each mounting tube section 1120 is threadedly connected to the corresponding through hole 1620 in the corresponding adapter 1600.

[0060] In this embodiment, the liquid medicine to be heated enters the liquid-containing chamber 1610 of one of the two adapters 1600 through a through hole 1620 that is not threadedly connected to the mounting pipe section 1120. Then, it enters the heating pipe section 1110 from the mounting pipe section 1120 corresponding to the adapter 1600. The heating pipe section 1110 heats the liquid medicine to be heated. The heated liquid medicine then enters the mounting pipe section 1120 corresponding to the other adapter 1600 and enters the liquid-containing chamber 1610 of the other adapter 1600. Finally, it exits the other adapter 1600 through a through hole 1620 that is not threadedly connected to the mounting pipe section 1120.

[0062] In this embodiment, the stirring shaft 1700 rotates around its own axis, and the stirring shaft 1700 drives the stirring blades 1710 to move synchronously. The stirring blades 1710 located in the installation pipe section 1120 stir the medicine in the heating pipe section 1110. On the one hand, this ensures that the medicine in the heating pipe section 1110 is in full contact with the inner wall of the heating pipe section 1110, ensuring that the medicine in each area of ​​the heating pipe section 1110 is heated to the same temperature. On the other hand, it generates a driving force that causes the medicine in the heating pipe section 1110 to flow into the liquid chamber 1610 through the installation pipe section 1120.

[0064] In this embodiment, by setting two stirring shafts 1700, and the outer peripheral surface of the stirring shafts 1700 is provided with stirring blades 1710, when the heating tube 1100 is long, the stirring of the stirring blades 1710 on the two stirring shafts 1700 can be used to make the medicine flow from one end of the heating tube 1100 to the other end of the heating tube 1100 with sufficient power.
