Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a medical heating blanket. Background Technology

[0002] With the development and increasing demand for clinical surgery, patients often experience weakness and difficulty maintaining a normal body temperature during surgery due to blood loss or other complications. Therefore, it is necessary to use a warming blanket to physically raise the patient's body temperature.

[0003] Traditionally, patients are kept warm primarily using electric blankets and hot water bottles. However, these methods are not effective at maintaining a constant temperature. Furthermore, due to these issues, current methods mainly involve heating gas using a gas-based heating device and then inflating it into a heating blanket. However, these inflatable blankets increase in thickness and expand after inflation, resulting in less contact area between the blanket and the patient's skin, leading to poor heating. Additionally, the inflated blanket is large and prone to floating, causing significant slippage and exposed skin areas when the patient moves. Because of the inflated support, the blanket remains on a single plane, making it difficult to bend and inconsistent with the body's curvature, further hindering effective heating.

[0004] At present, most inflatable heating blankets blow high-speed gas directly outward through the fan of the heating device. Because the air inlet is relatively small, the air flow rate is large when it enters, and it will rush directly to the center, resulting in higher temperature in the middle and lower temperature at the edges, uneven heating, and in severe cases, it can cause burns to the skin of certain patients. Summary of the Invention

[0017] In a preferred embodiment of the present invention, the exhaust assembly includes an inner connecting ring and an outer connecting ring. An exhaust hole is provided on the surface of the inner connecting ring, and a sealing valve is fixed on the surface of the outer connecting ring. The exhaust hole and the sealing valve are positioned corresponding to each other.

[0018] In a preferred embodiment of the present invention, there are several exhaust components, which are evenly distributed on the surface of the heating blanket body.

[0019] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0020] 1. This medical heating blanket can disrupt the high-temperature gas in the main body of the heating blanket, thereby avoiding the problem of uneven heating caused by a large airflow velocity rushing directly to the center, resulting in a higher temperature in the middle and a lower temperature at the edges. At the same time, with the transverse and longitudinal pressing strips on the surface of the heating area, the heating area can be divided into several heating cavities. The high-temperature gas passes through several heating cavities, thereby preventing the rapid expansion of the center of the heating blanket and making it easy to bend.

[0021] 2. This medical heating blanket incorporates an airflow disturbance device at its air inlet and an air inlet baffle to ensure that hot air can only enter through the air inlet of the air ring. The high-speed hot air then drives the fan blades inside the air ring to rotate, dispersing the hot air into various directions before it is blown out through the surrounding air ring outlets. This process of circulating, dispersing, and slowing down the heated gas entering the device, along with multiple sets of air outlets at different locations, ensures a high degree of uniform low-speed airflow, significantly reducing local flow velocity, increasing the airflow diffusion angle, and enhancing the uniformity of heating during the heating process.

[0022] 3. This medical heating blanket, by setting multiple parallel long straight pressed edges on the heating blanket, divides the heating area of ​​the heating blanket into multiple parallel small heating cavities. The modular heating method can better improve the uniformity of heating and improve the heating effect.

[0023] 4. This medical heating blanket features short pressing edges horizontally on each of the parallel small heating cavities, with pre-drilled hot air vents on these edges. This semi-open design cuts off the longer heating cavities, significantly reducing the gas filling level and pressure at the short pressing edges. This also lowers the blanket's stiffness at these edges, making it easier to bend and fold, better adapting to different body postures and achieving a better fit. This enhances the heating effect.

[0024] 5. This medical heating blanket has multiple sets of magnetic attraction devices evenly distributed on both sides. Two attraction strips with opposite polarities are connected by a wide connecting strip. One attraction strip is fixed to the heating blanket, while the other is suspended and can be directly attracted to the metal bed frame of the operating table. It can also clamp and attract bed sheets or similar items on the operating table between the two attraction strips, forming an integrated connection between the heating blanket and the operating table or the bed sheet underneath. This effectively prevents the heating blanket from moving significantly during patient movement, which could lead to exposure of the body surface or heat loss, thus effectively improving the heating and heat preservation effect of the heating blanket.

[0025] 6. This medical heating blanket features a simple structure and stable connection components, making it less prone to loosening during use and effectively improving the stability and safety of the equipment.

[0026] 7. This medical heating blanket has multiple vent holes evenly distributed on both sides of the inflation area. Each vent hole has a multi-lobed sealing valve structure. The vent hole will only open the sealing valve to release air when the air pressure reaches a certain threshold, allowing hot air to flow within the heating chamber area. This ensures continuous heating of the heating chamber and maintains a constant temperature. The multi-lobed structure also prevents air from being released when the air cavity is not fully established in the initial stage of air intake, effectively increasing the cavity establishment time and improving heating efficiency.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0038] A medical heating blanket includes: a heating blanket body 1, and further includes a flow-dispersing component 2, a magnetic attraction strip 3, a connecting component 5, and an exhaust component 6 disposed on the surface of the heating blanket body 1. The heating blanket body 1 is fixed with an air supply hose 4 through the connecting component 5. This medical heating blanket can disturb the high-temperature gas in the heating blanket body 1, thereby avoiding the problem of uneven heating caused by a large airflow velocity during intake, which would directly rush to the center and result in a higher temperature in the middle and a lower temperature at the edges. At the same time, the connecting component 5 is provided, which is simple to operate, easy to connect and disassemble, and the connection is stable and not easy to loosen during use, effectively improving the stability and safety of the equipment during use.

[0039] The main body 1 of the heating blanket includes a head area 110, a heating area 120, an inflation area 130 and a pressing edge area 140, with the head area 110 corresponding to the position of the human head;

[0040] The turbulence component 2 includes a wind deflector 210, a wind ring 220, a rotating shaft 230 and a fan blade 240 disposed inside the wind ring 220, and an air inlet 221 and an air outlet 222 are also provided on the surface of the wind ring 220.

[0041] The connecting component 5 includes a connecting collar 510, a connecting upper cover 520, a connecting rear cover 530, a sliding push plate 540, and a spring piece 550. The surface of the connecting upper cover 520 is provided with a toothed buckle 521, and a number of spring pieces 550 are evenly arranged between the connecting rear cover 530 and the sliding push plate 540. The surface of the connecting collar 510 is also provided with a connecting clip 570 for fixing.

[0042] An air inlet is provided at the connection between the air supply hose 4 and the main body 1 of the heating blanket. A baffle plate 210 is located on both sides of the air inlet, and a fan ring 220 is located on the side of the baffle plate 210 corresponding to the air inlet. An air inlet 221 corresponds to the air inlet. A connecting collar 510 passes through the air inlet and is connected and fixed to the connecting cover 520 via a snap fastener 521. The connecting collar 510 and the connecting cover 520 are pressed tightly against the fabric layer of the air inlet. A rotating shaft 230 is mounted inside the main body 1 of the heating blanket via bearings. Fan blades 240 are fixed to the surface of the rotating shaft 230 and are evenly arranged. Several air outlets 222 are evenly arranged on the surface of the fan ring 220. This medical heating blanket... By setting an airflow disturbance device at the air inlet 221 of the heating blanket and setting an air inlet baffle at the air inlet 221, hot air can only enter from the air inlet 221 of the air ring 220. Then, driven by the high-speed flow of hot air, the fan blades 240 inside the air ring 220 rotate, causing the hot air entering the air ring 220 to flow in all directions. Then, it is blown out through the air outlet 222 of the surrounding air ring 220. The heating gas rushing into the equipment is subjected to circling, dispersing, and deceleration. Multiple sets of circling air outlets 222 at different positions provide more uniform low-speed air delivery, which greatly reduces the local flow velocity, increases the airflow diffusion angle, and increases the uniformity of heating of the heating blanket.

[0043] The surface of the heating area 120 is provided with transverse pressing strips 121 and longitudinal pressing strips 122. The transverse pressing strips 121 and longitudinal pressing strips 122 can divide the heating area 120 into several heating cavities. This medical heating blanket, by setting multiple parallel long straight pressing edges on the heating blanket, divides the heating area of ​​the heating blanket into multiple parallel small heating cavities. The modular heating method can better improve the uniformity of heating and improve the heating effect.

[0044] The heating cavity surface is provided with ventilation bridge holes 123; this medical heating blanket, by setting short pressing edges laterally on each parallel small heating cavity and reserving hot air ventilation bridge holes 123 on the pressing edges, partially cuts off the longer heating cavity, significantly reducing the degree of gas filling and the gas pressure at the short pressing edges, reducing the hardness of the heating blanket at the short pressing edges, making it easier to bend the heating blanket to better adapt to different postures of the human body, so as to achieve a better fit between the heating blanket and the human body and improve the heating effect.

[0045] A connecting latch 560 structure is provided adjacent to the inner ring of the connecting collar 510. The connecting latch 560 structure includes an inlet groove 561 and a push groove 562. A limiting block is provided on one side of the inlet groove 561 and the push groove 562. The sliding push plate 540 is slidably connected to the corresponding sliding groove on the inner wall of the connecting collar 510 through a slider. One end of the spring piece 550 is fixedly connected to the connecting rear cover 530, and the other end of the spring piece 550 is in contact with the sliding push plate 540.

[0046] A connecting latch 560 is provided adjacent to the inner ring of the connecting collar 510. The connecting latch 560 includes an inlet groove 561 and a push groove 562. A tightening protrusion 541 is provided on the side of the sliding push plate 540 corresponding to the push groove 562. The position of the tightening protrusion 541 corresponds one-to-one with the inlet groove 561 and the push groove 562. This medical heating blanket, by setting the connecting component 5, has a simple structure and operation, stable connection, and is not easy to loosen during use, effectively improving the stability and safety of the equipment during use.

[0047] The magnetic attraction strip 3 consists of two oppositely attracted strips connected by a wide connecting strip. One attraction strip is fixed to the heating blanket, while the other is suspended. Several sets of magnetic attraction strips 3 are evenly distributed on both sides of the heating blanket body 1. This medical heating blanket has multiple sets of magnetic attraction devices evenly provided on both sides. Two oppositely attracted strips are connected by a wide connecting strip. One attraction strip is fixed to the heating blanket, while the other is suspended. It can be directly attracted to the metal bed frame of the operating table. It can also clamp and attract bed sheets or similar items on the operating table between the two attraction strips, forming an integrated connection between the heating blanket and the operating table or the bottom bed sheet. This effectively prevents the heating blanket from moving significantly during patient movement, which could lead to exposure of the body surface or heat loss, thus effectively improving the heating and heat preservation effect of the heating blanket.

[0048] The exhaust assembly 6 includes an inner connecting ring 610 and an outer connecting ring 620. An exhaust hole 630 is formed on the surface of the inner connecting ring 610, and a sealing valve 640 is fixed to the surface of the outer connecting ring 620. The exhaust holes 630 and the sealing valve 640 are positioned correspondingly. Several exhaust assemblies 6 are evenly distributed on the surface of the heating blanket body 1. This medical heating blanket has multiple exhaust holes 630 evenly distributed on both sides of the inflation area 130. Each exhaust hole 630 has a multi-lobed sealing valve 640 structure. Exhaust is only released when the air pressure reaches a certain threshold, allowing hot air to flow within the heating chamber area, ensuring continuous heating and a constant temperature effect. The multi-lobed structure prevents exhaust when the cavity is not fully established in the initial air intake stage, effectively increasing the cavity establishment time and heating efficiency.

[0049] The working principle of this invention is as follows:

[0050] First, place the device in a suitable position. Then, align the connecting clip 570 at one end of the air supply hose 4 with the inlet groove 561 inside the connecting collar 510 and push it inward. This will push the sliding push plate 540 inward and simultaneously deform the spring 550. Then, rotate the connector clockwise until it is blocked by the limit block. Release the air supply hose connector. At the moment of release, the restoring force of the spring 550 will push the sliding push plate 540 in the opposite direction. The push of the clamping protrusion 541 on the sliding push plate 540 will push the air supply hose 4 in the opposite direction, causing the connecting clip 570 on the air supply hose 4 to embed into the push groove 562, thus connecting the air supply hose 4. To remove it, simply push the hose connector inward and rotate it counterclockwise to the limit block, then release it. It will then automatically pop out under the action of the spring 550.

[0051] Subsequently, the heating blanket body 1 is fixed to the metal bed frame of the operating table by magnetic attraction strip 3, and hot air is delivered into the heating blanket body 1 through air delivery hose 4. At the same time, an air inlet baffle is set at the air inlet 221 so that the hot air can only enter from the air inlet 221 of the air ring 220. Then, driven by the high-speed flow of hot air, the fan blades 240 inside the air ring 220 rotate, causing the hot air entering the air ring 220 to flow in all directions. Then, it is blown out through the air outlet 222 of the surrounding air ring 220, so that the heated gas rushing into the equipment is circulated, dispersed and slowed down.
