Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a warming blanket. Background Art

[0002] A warming blanket is a medical device used to help patients or patients undergoing surgery maintain body temperature. During the rescue process, especially in cold weather conditions, trapped people or patients may be at risk of hypothermia. A warming blanket can help increase and maintain body temperature.

[0003] The heating blanket is heated by connecting a pipe on the outside of a heating device to the heating blanket, and hot air is transported through the pipe to make the heating blanket expand and heat up. The existing method is to fix the pipe with Velcro on the heating blanket so that the pipe can normally transport the hot air generated by the heating device. When medical staff provide first aid to patients, due to the harsh environment encountered during rescue and disaster relief, when there are many ground particles, the Velcro surface has hook-shaped fibers. If the Velcro is used for a long time, dirt and fibers may accumulate on the surface of the Velcro, resulting in low adhesion of the Velcro surface, and thus unstable fixing of the pipe. When the Velcro is disconnected from the pipe, the hot air output from the pipe blows large particles on the ground into the interior of the heating blanket, thereby affecting the use of the heating blanket.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a heating blanket, which includes a blanket body 100, a connecting assembly 200 provided on the blanket body 100, a pressurizing assembly 300 and a cleaning assembly 400 provided on the connecting assembly 200;

[0033] The connection assembly 200 includes a connection base 201 disposed on the blanket body 100. The connection base 201 is connected to the air inlet of the blanket body 100. An air bag 202 is disposed within the connection base 201. The expansion of the air bag 202 secures the pipe outside the heating device within the connection base 201. A filter 203 is disposed on the connection base 201 to prevent particulate matter from entering the interior of the blanket body 100.

[0034] The pressurizing assembly 300 is embedded in the connecting seat 201 and connected to the airbag 202. The pressurizing assembly 300 drives the airbag 202 to expand, so that the expansion of the airbag 202 fixes the pipe outside the heating device in the connecting seat 201.

[0035] The cleaning component 400 is embedded in the connecting seat 201 and is connected to the filter 203 and the pressurizing component 300. The cleaning component 400 includes a positioning member 403 arranged in the connecting seat 201. The positioning member 403 positions the airbag 202 in two modes of deflation and inflation. When the airbag 202 is deflated, the gas discharged from the airbag 202 is driven by the cleaning component 400 to blow away the particles on the surface of the filter 203, thereby cleaning the particles on the surface of the filter 203 and preventing the particles on the surface of the filter 203 from clogging the filter 203.

[0036] During use, the pipe on the outside of the heating device is inserted into the connecting seat 201, and the pressurizing component 300 drives the airbag 202 to expand. The expanded airbag 202 fixes the pipe on the outside of the heating device in the connecting seat 201. When the heating device finishes working, the cleaning component 400 drives the airbag 202 to release pressure, and discharges the released gas toward the surface of the filter 203 to clean the particulate matter on the surface of the filter 203 to prevent the particulate matter on the surface of the filter 203 from clogging the filter 203.

[0037] Example 2

[0038] Reference Figure 1-5 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: the pressurizing assembly 300 includes a guide cylinder 1 301 arranged on the connecting seat 201, a guide cylinder 2 302 is fixedly passed through the connecting seat 201, the guide cylinder 2 302 is communicated with the blanket body 100, the filter 203 is arranged at the port of the guide cylinder 2 302, a rotating cylinder 303 is rotatably arranged on the outer side of the guide cylinder 1 301, the airbag 202 is arranged on the inner side of the guide cylinder 1 301, and the rotating cylinder 303 and the guide cylinder 1 301 are both provided with mutually adapted A connecting hole 304 and a cavity 305 are provided on the connecting seat 201. The airbag 202 is connected to the cavity 305 through the connecting hole 304. When in use, the pipe on the outside of the heating device is inserted between the guide cylinder 1 301 and the guide cylinder 2 302. When the airbag 202 expands, the airbag 202 squeezes the pipe on the outside of the heating device so that the pipe on the outside of the heating device is close to the outer wall of the guide cylinder 2 302. Since the airbag 202 is connected to the cavity 305 through the connecting hole 304, it is only necessary to pressurize the cavity 305 to pressurize the airbag 202.

[0039] Furthermore, a pressurizing cylinder 306 is provided in the connecting seat 201 , and a transmission component 307 is provided on the pressurizing cylinder 306 , and the cavity 305 is pressurized through the transmission component 307 .

[0040] Furthermore, the transmission member 307 includes a piston 307a slidably arranged in the pressure cylinder 306, and the pressure cylinder 306 is respectively connected to two air inlet pipes 307b and air outlet pipes 307c, one end of the two air inlet pipes 307b is fixedly passed through the connecting seat 201 and is communicated with the outside world, and the other end is fixedly passed through the upper and lower ends of the pressure cylinder 306 and is communicated with the pressure cylinder 306, one end of the two air outlet pipes 307c is fixedly passed through the connecting seat 201 and is communicated with the cavity 305, and the other end is fixedly passed through the upper and lower ends of the pressure cylinder 306 and is communicated with the pressure cylinder 306, a one-way valve 1 307d is provided in each of the two air inlet pipes 307b, and a one-way valve 2 307e is provided in each of the two air outlet pipes 307c. When the piston 307a moves along When the pressure cylinder 306 moves upward, negative pressure is generated in the pressure cylinder 306, and the air inlet pipe 307b at the lower end of the pressure cylinder 306 draws air, and the gas enters the pressure cylinder 306 through the guide valve 1 on the air inlet pipe 307b. At the same time, the piston 307a squeezes the gas in the pressure cylinder 306 into the air outlet pipe 307c at the upper end of the pressure cylinder 306, and then discharges it into the cavity 305 through the guide valve 2 in the air outlet pipe 307c. Similarly, when the piston 307a moves downward, the gas enters from the air inlet pipe 307b at the upper end of the pressure cylinder 306, and the gas is discharged into the cavity 305 from the air outlet pipe 307c at the lower end of the pressure cylinder 306. Then, when the piston 307a moves back and forth once along the pressure cylinder 306, the cavity 305 is pressurized twice, thereby improving work efficiency.

[0041] Furthermore, a driving member 308 is provided in the pressurizing cylinder 306 , and the driving member 308 drives the piston 307 a to move.

[0042] Furthermore, the driving member 308 includes a guide column 308a arranged on the piston 307a, and the guide column 308a is slidably arranged on the pressure cylinder 306. A push plate 308b is provided at the end of the guide column 308a. By pushing the push plate 308b, the push plate 308b drives the guide column 308a to slide along the pressure cylinder 306, and the piston 307a on the guide column 308a moves synchronously with it, thereby pressurizing the cavity 305.

[0043] Furthermore, a spring 309 is provided in the pressurizing cylinder 306 , and both ends of the spring 309 are respectively connected to the corresponding surfaces of the piston 307 a and the pressurizing cylinder 306 , and the elasticity of the spring 309 drives the piston 307 a to reset.

[0044] During use, when the airbag 202 needs to be pressurized, the push plate 308b is pushed, and the push plate 308b drives the guide column 308a to slide along the pressurizing cylinder 306, and the piston 307a on the guide column 308a moves synchronously with it, and then the piston 307a moves back and forth once, and the cavity 305 is pressurized twice. The gas in the cavity 305 enters from the connecting hole 304. Because the guide cylinder 301 coincides with the connecting hole 304 on the rotating cylinder 303, the pressurized gas enters the airbag 202, causing the airbag 202 to expand. The expanded airbag 202 squeezes and fixes the pipe on the outside of the heating device.

[0045] The remaining structures are the same as those of Example 1.

[0046] Example 3

[0047] Reference Figure 1-5 , which is the third embodiment of the present utility model. This embodiment is different from the second embodiment in that: the cleaning component 400 includes a matching hole 1 401 set on the rotating cylinder 303, and a matching hole 2 402 is set on the guide cylinder 1 301. When the matching hole 1 401 coincides with the matching hole 2 402, the cavity 305 is connected to the outside world, thereby causing the gas in the cavity 305 to be discharged. Since the airbag 202 is connected to the cavity 305, the airbag 202 is depressurized. When the matching hole 1 401 and the matching hole 2 402 do not coincide with each other, the cavity 305 is not connected to the outside world.

[0048] Furthermore, the positioning member 403 allows the first mating hole 401 and the second mating hole 402 to be positioned in two modes: overlapped and non-overlapped.

[0049] Furthermore, the positioning member 403 includes a positioning block 403a provided on the rotating cylinder 303, and a magnet 1 403b and a magnet 2 403c are respectively provided on the connecting seat 201. The positioning block 403a is made of iron. When the rotating cylinder 303 is rotated, the positioning block 403a on the rotating cylinder 303 and the magnet 2 403c are attracted to each other. At this time, the matching hole 1 401 and the matching hole 2 402 coincide with each other, and the matching hole 1 401 and the matching hole 2 402 are aligned with the surface of the filter 203. The gas is discharged from between the overlapping matching holes 1 401 and the matching holes 2 402, so that the particulate matter on the surface of the filter 203 is blown away by the discharged gas. When the rotating cylinder 303 is rotated in the opposite direction and the positioning block 403a and the magnet 1 403 are attracted to each other, the matching hole 1 401 and the matching hole 2 402 do not coincide with each other, and the airbag 202 remains in an inflated state.

[0050] The remaining structures are the same as those of Example 2.

[0051] Working principle: Insert the pipe outside the heating device into the connecting seat 201, and push the push plate 308b, which drives the guide column 308a to slide along the pressurizing cylinder 306. The piston 307a on the guide column 308a moves synchronously with it, and then the piston 307a moves back and forth once, pressurizing the cavity 305 twice. The gas in the cavity 305 enters from the connecting hole 304. At this time, the guide cylinder 301 and the connecting hole 304 on the rotating cylinder 303 coincide with each other, so that the pressurized gas enters the airbag 202, causing the airbag 202 to expand. The expanded airbag 202 02 squeezes and fixes the pipe outside the heating device. When the blanket body 100 finishes working, the rotating cylinder 303 is rotated, and the positioning block 403a on the rotating cylinder 303 is attracted by the second magnet 403c. At this time, the first matching hole 401 and the second matching hole 402 overlap, and the first matching hole 401 and the second matching hole 402 are aligned with the surface of the filter 203. The gas in the cavity 305 is discharged from between the overlapping first matching hole 401 and the second matching hole 402. Therefore, the particles on the surface of the filter 203 are blown away by the discharged gas, so that the connection between the connecting seat 201 and the blanket body 100 is always in a dust-free state.
