[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0028] like Figure 1-Figure 3 As shown, in the first embodiment of the oxygen distributor of the present invention, the oxygen distributor 10 comprises an oxygen delivery assembly 100 with a hollow structure, which is used to receive oxygen electrolytically output by an oxygen generator (not shown).

[0029] Specifically, the oxygen delivery assembly 100 is configured as a hollow structure 10a;

[0030] An input end of the oxygen delivery component 100 is used to receive oxygen input from an electrolysis component (such as an oxygen generator or an electrolysis module); and

[0031] like Figure 4 As shown, a single-circuit oxygen distribution pipe 10c is provided in the oxygen delivery assembly 100.

[0032] The contact surface of the oxygen distribution tube 100a with the skin surface is provided as an oxygen-permeable but liquid-impermeable layer 101;

[0033] The oxygen-permeable and liquid-impermeable layer 101 is made of an ePTEF composite membrane, specifically an ePTFE bubble point composite material, with an air permeability of 1-2L / M2 / S and a thickness set between 0.18mm and 0.25mm. The ePTFE membrane has a mesh microporous structure, and an air flow rate of about 3.6mm per second passing through the e-PTFE membrane.

[0034] It can be understood that the user applies the oxygen delivery component 100 to the wound, and the contact surface with the wound is oxygen-permeable but liquid-impermeable, so that oxygen continues to flow into the wound, and the suppuration of the wound cannot enter its oxygen distribution pipe 10c through the oxygen-permeable but liquid-impermeable layer 101, thereby maintaining the smooth flow of oxygen output.

[0035] Among them, ePTFE is a microporous membrane formed by expanding and stretching polytetrafluoroethylene as raw material. Its surface is covered with fibrillar micropores, with up to 9 billion micropores per square inch. The cross-section is a network structure. The three-dimensional structure of the holes has very complex structures such as mesh connections, hole nesting, and channel bending. The diameter varies between 0.1-0.5nm. The composite fabric is made of expanded polytetrafluoroethylene film (ePTFE) and polyester fiber through a special process.

[0036] Using this technical solution, the oxygen-permeable and liquid-impermeable layer 101 is selected to be made of ePTEF composite film, and its air permeability is 1-2L / M2 / S, so as to solve the high material cost and complex process required in the prior art, thereby effectively reducing the cost of use.

[0037] In some embodiments, the pore size of the ePTEF composite membrane can be set to 0.25 nm.

[0038] In some embodiments, the pore size of the ePTEF composite membrane can be set to 0.22 nm.

[0039] In some embodiments, the pore size of the ePTEF composite membrane can be set to 0.20 nm.

[0040] In some embodiments, Figure 1-Figure 3 As shown, in order to ensure the pressure in the oxygen distribution tube 10c, the opposite surface of the oxygen-permeable and liquid-impermeable layer 101 can be set as an airtight and watertight layer 105. It can be understood that the opposite surface of the oxygen distribution tube 100a and the skin surface contact surface is set as an airtight and watertight layer 105 to ensure that oxygen can be ventilated toward the oxygen-permeable and liquid-impermeable layer 101, thereby effectively increasing the oxygen content around the wound.

[0041] The air-impermeable and water-impermeable layer 105 and the oxygen-permeable and liquid-impermeable layer 101 are ultrasonically welded at their inner edges 10b and outer edges (not shown) to ensure the sealing of the combination of the two.

[0042] In some embodiments, the air-impermeable and water-impermeable layer 105 is made of a TPU film, and the thickness thereof is in the range of 0.03 mm to 0.06 mm.

[0043] In some embodiments, Figure 2 As shown, at least one layer of porous material 104 is arranged along the axial direction of the oxygen-permeable and liquid-impermeable layer 101 and the air-impermeable and water-impermeable layer 105, which supports the ePTFE composite membrane and the TPU membrane after welding so that oxygen can flow quickly between them.

[0044] The porous material 104 is selected to be porous foam.

[0045] Porous foam may be distributed throughout the oxygen distribution tube 10c, advantageously keeping the tube open and able to conduct oxygen even if pressure is applied on top of the air and water impermeable layer 105, such as by applying a compressive bandage to the oxygen distribution tube 100a.

[0046] Alternatively, at least a portion of the tube wall of the oxygen distribution tube 100a may have sufficient rigidity or may be reinforced to prevent the tube wall from breaking.

[0047] The inner surface of the oxygen distribution tube 100a and the porous foam inside the tube are hydrophobic to prevent or reduce wetting or to carry out exudates through capillary action, thereby preventing exudates from entering the tube to avoid infection.

[0048] In some embodiments, Figure 2 As shown, at least one first hot-melt film 102 is disposed between the porous material 104 and the oxygen-permeable but liquid-impermeable layer 101, or

[0049] At least one first hot-melt film 102 is disposed between the second hot-melt film 103 and the oxygen-permeable and liquid-impermeable layer 101;

[0050] In the attached state, the first hot-melt film 102 is attached to one side of the oxygen-permeable and liquid-impermeable layer 101 , and is integrated with the oxygen-permeable and liquid-impermeable layer 101 .

[0051] In some embodiments, Figure 2 As shown, at least one second hot-melt film 103 is disposed along the porous material 104 and the air-impermeable and water-impermeable layer 105; or

[0052] At least one layer of porous material 104 is disposed in the direction of the second hot-melt film 103 and the air-impermeable and water-impermeable layer 105;

[0053] It can be understood that one side of the second hot-melt film 103 can be attached to one side of the air-impermeable and water-impermeable layer 105, and one side of the second hot-melt film 103 can be attached to one side of the porous material 104; or

[0054] One side of the porous material 104 may be bonded to one side of the air-impermeable and water-impermeable layer 105 , and the other side of the porous material 104 may be bonded to one side of the second hot-melt film 103 .

[0055] The first hot-melt film 102 can be used as a flux to achieve better welding effects among the ePTFE composite film, the TPU film and the porous material 104 .

[0056] In a second aspect, an oxygen generator comprises: an oxygen distributor 10 according to any one of the above items; and an oxygen generator, whose oxygen output end is connected to the input end of the oxygen distributor through a pipeline and provides oxygen to the oxygen delivery component 100 of the oxygen distributor.

[0057] When the DVM value of the oxygen generator is 60mA, and the oxygen delivery per hour is 11ml-14ml, the pore size of the ePTEF composite membrane is selected to be 0.25nm, corresponding to the "laid surface" can reach an oxygen concentration of 55.08%, and can be maintained for up to 4 hours;

[0058] When the DVM value of the oxygen generator is 60mA, and the oxygen delivery per hour is 11ml-14ml, the pore size of the ePTEF composite membrane is selected to be 0.22nm, corresponding to the "laid surface" can reach an oxygen concentration of 52.07%, and can be maintained for up to 5 hours;

[0059] When the DVM value of the oxygen generator is 60mA, and the oxygen supply per hour is 11ml-14ml, the pore size of the ePTEF composite membrane is selected to be 0.20nm, corresponding to the "laid surface" can reach an oxygen concentration of 50.05%, and can be maintained for up to 6 hours.

[0060] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
