AI Technical Summary
The thermal insulation effect of existing electromagnetic spectrum therapy devices is limited, mainly because the thermal insulation material is only attached to the heating parts, which cannot effectively reduce the loss of heat.
Using a vacuum heat shield assembly, including an inner and outer shield, a first and second insulating layer, the insulating layer is provided on both sides of the heating layer and vacuuming in the cavity to reduce heat dissipation, combining the inner side of the mirror and artificial mica material To improve thermal insulation performance.
It significantly improves the thermal insulation effect. Compared with the traditional single thermal insulation method, it more effectively reduces heat loss and enhances the thermal insulation performance of medical devices.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a medical device with vacuum heat insulation performance. Background Art
[0002] In the medical device industry, there is a specific electromagnetic spectrum therapeutic device, which was invented in 1979 and has been used for more than 40 years. There are dozens of manufacturers in this industry, and the annual production and sales volume has reached nearly 3 million units, making a huge contribution to society.
[0003] However, since the core component of this product, the treatment head, is electrically heated to produce its therapeutic effect, the thermal insulation components of the product have traditionally been made of materials such as aluminum silicate fiber cotton, which are placed outside the heating layer as thermal insulation. Although this method has some effect on the thermal insulation of the product, the insulation effect is limited. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model proposes a medical device with vacuum insulation performance to solve the technical problem mentioned in the above background technology that the treatment head of the existing electromagnetic spectrum therapy device usually only uses insulation material to stick to the outside of the heating element for insulation.
[0005] In order to solve this technical problem, the technical solution adopted by the utility model is:
[0006] A medical device with vacuum insulation performance includes a vacuum insulation cover assembly, a first insulation layer, a heating layer, a second insulation layer and an element plate layer;
[0007] The first insulating layer is provided in the vacuum heat insulation cover assembly;
[0008] The heating layer is also provided on the back of the first insulating layer;
[0009] The second insulating layer is also provided on the back of the heating layer;
[0010] The element plate layer is also arranged on the back of the heating layer.
[0011] Furthermore, the vacuum heat insulation cover assembly comprises an outer cover and an inner cover; the outer cover and the inner cover are connected to form a closed cover body with a cavity, and the cavity is evacuated.
[0012] Further, the vacuum is drawn to a negative pressure of 0.5-5 kg.
[0013] Furthermore, the inner side surfaces of the inner cover and the outer cover are mirror surfaces.
[0014] Furthermore, the first insulating layer and the second insulating layer are made of artificial mica.
[0015] Compared with the prior art, the advancement of this application is:
[0016] There are insulating layers on both sides of the heating layer, which can initially prevent the heating element from dissipating heat from the front and back. At the same time, there is a positive vacuum heat insulation cover component on the front, which can further reduce the heat dissipation from the front through vacuum. Therefore, compared with traditional single insulation, by adding a vacuum heat insulation cover component outside the insulation material, better insulation can be achieved.

The element plate layer 5 is formed by sintering multiple elements on a metal or ceramic plate through a high-temperature melting process; the element plate layer 5 is an element plate with therapeutic effects, which can generate electromagnetic waves with multiple element oscillation signals after being heated.

The inner cover 12 and the outer cover 11 can be made of two metal stampings by welding. It can also be made by blow molding or glass blowing; it can also be made by injection molding through frequency modulation welding and bonding. After the inner cover 12 and the outer cover 11 are connected together, a vacuum point is opened on the inner cover 12 or the outer cover 11 to perform vacuuming, and the vacuum point is closed after the vacuuming is completed.
[0029] In other schemes, vacuuming reaches negative pressure 0.5-5 kg. Under this value, the vacuum of inner cover 12 and outer cover 11 can be extracted preferably.
