[0002] In daily life and medical care, there are often precautions against pressure shocks, such as sports pads, car seats, etc., or the need for pressure buffering, such as chair cushions, mattresses, insoles or medical care mattresses, bedsore protection pads or economy class syndrome protection pads to avoid long-term sitting. Especially modern people often sit for long periods of time due to computer use, which can cause lower limb edema in mild cases, breathing difficulties in severe cases, and even stroke or death in economy class syndrome, so the need for pressure buffering is even more urgent. In the past, the solution to pressure shock and pressure buffering was mostly achieved by the arrangement and combination of various materials, or compounding, bonding, stacking, or air bags or water bags to achieve the purpose of pressure buffering, but the effect was limited; material scientists also attempted to create new pressure-resistant materials through material synthesis and development technology, such as memory foam or gel or various material foams, but such a single synthetic material thinking can obtain good materials but is still limited by the microstructure of the basic material. For this reason, a dynamic pressure-absorbing medical auxiliary pad with a foamed anti-bird's nest microstructure is designed. Summary of the invention

DETAILED DESCRIPTION
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-Figure 3 As shown, a dynamic pressure-absorbing medical auxiliary pad with a foamed anti-bird's nest microstructure includes a foamed main body 500, in which a plurality of foamed anti-bird's nest microstructures 100 are arranged, in which a high-density interlaced fiber positioning core body 110 is arranged, on which a low-density interlaced fiber pressure transfer layer 130 is arranged, and on which a plurality of air buffer cavities 300 are arranged.
[0020] A plurality of air buffer cavities 300 are disposed between adjacent foamed anti-bird's nest microstructures 100 .
[0021] Adjacent foamed anti-bird's nest microstructures 100 are connected by the low-density interlaced fiber pressure transfer layer 130 .
[0022] The number of the foamed anti-bird's nest microstructures 100 is plural.
[0023] The number of the air buffer chambers 300 is plural.
[0024] The foamed reverse bird's nest microstructure 100 is introduced into the foaming reaction system before the foamed main body 500 is formed or when the foamed main body 500 is formed. The foamed reverse bird's nest microstructure 100 is obtained by reacting a third reaction mixture selected from polyol-based compounds, polyamine-based compounds, fiber oligomers and combinations thereof with a fourth reaction mixture selected from polyacid-based compounds, polycyano-based compounds and combinations thereof, wherein the fiber oligomer is selected from the group consisting of polymethacrylate, silica gel, rubber, polypropylene, polyethylene, polycarbonate, polylactic acid, shape memory polymer, temperature-molding polymer, and microwave-molding polymer.
[0025] The foamed anti-bird's nest microstructure 100 is made of a group selected from polymethacrylate, silicone, rubber, polypropylene, polyethylene, polycarbonate, polylactic acid, shape memory polymer, temperature plastic polymer, and microwave plastic polymer.
[0026] The foaming body 500 is obtained by reacting a first reaction mixture selected from a polyol-based compound, a polyamine-based compound and a combination thereof with a second reaction mixture selected from a polyacid-based compound, a polycyano-based compound and a combination thereof. The foaming body 500 is selected from the group consisting of silica gel, rubber, polypropylene foam, polyethylene foam, polylactic acid foam, shape memory polymer foam, memory foam, space cotton and a combination thereof.
[0027] The foamed anti-bird's nest microstructure 100 is connected to each other through the low-density interlaced fiber pressure transmission layer 130. When subjected to stress in clinical applications, such as Figure 2 As shown, the human body pressure part 1000 transmits the weight or pressure of the human body through a plurality of foamed anti-bird's nest microstructures 100 and the air buffer chambers 300 evenly distributed therein, which can create multiple sections of dynamic pressure buffer reaction forces, absorb pressure, and form dynamic suction pressure, which is quite suitable for strong impact buffering or long-term pressure resistance needs.
[0028] Selectively, the foaming anti-bird's nest microstructure 100 is introduced into the foaming reaction system before the foaming main body 500 is formed or when the foaming main body 500 is formed. The foaming main body 500 is introduced into the foaming reaction system before it is formed, which means that the foaming anti-bird's nest microstructure 100 is first prepared by the first stage reaction, and then the foaming anti-bird's nest microstructure 100 is dispersed in the foaming reaction system and reacted. The foaming main body 500 is introduced into the foaming reaction system when it is formed, which means that when the foaming reaction system reacts, the foaming anti-bird's nest microstructure 100 is first reacted to obtain the foaming anti-bird's nest microstructure 100 through the adjustment of reaction parameters, and then the foaming anti-bird's nest microstructure 100 is connected and foamed.
[0029] In a specific application, the foaming body 500 is obtained by reacting a first reaction mixture selected from a polyol-based compound, a polyamine-based compound and a combination thereof with a second reaction mixture selected from a polyacid-based compound, a polycyano-based compound and a combination thereof to obtain a branched polyurethane foam. In a specific application, the foaming anti-bird's nest microstructure 100 can also be obtained by reacting a third reaction mixture selected from a polyol-based compound, a polyamine-based compound and a combination thereof with a fourth reaction mixture selected from a polyacid-based compound, a polycyano-based compound and a combination thereof to obtain polyurethane molecules.
[0030] Optionally, the foamed anti-bird's nest microstructure 100 may be realized by a group selected from polymethacrylate, silicone, rubber, polypropylene, polyethylene, polycarbonate, polylactic acid, shape memory polymer, temperature plastic polymer, microwave plastic polymer. And the foamed main body 500 may be realized by a group selected from silicone, rubber, polypropylene foam, polyethylene foam, polylactic acid foam, shape memory polymer foam, memory foam, space cotton and a combination thereof. In terms of application, in addition to medical beds, elderly care beds, wheelchair pads, dialysis chair pads, bedsore care, etc. can all be used.
[0031] The dynamic pressure-absorbing medical auxiliary pad 10 of the present technical solution has an ingenious structural design, strong practicality, and super impact resistance. Through this dynamic pressure-absorbing medical auxiliary pad 10, pressure shock and pressure buffering can be effectively avoided. It can be used in medical beds, elderly care beds, wheelchair pads, dialysis chair pads, bedsore care, etc., and is widely used in clinical care.
[0032] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
