One end of the rubber sealing gasket 172 is fixedly connected with the annular clamping ring 171 in a riveting mode, and the riveting part can be coated with adhesive to enhance the sealing effect; the rubber tearing plate 12 and the tearing bulge 14 can be fixedly connected in a riveting mode, and the riveting position can be coated with adhesive to enhance the sealing effect.

The specific preparation process comprises the steps of respectively processing and manufacturing the liquid medicine storage bag 1, the waterproof breathable film-coated non-woven fabric bag 15, the flat water squeezing bag 32 and the transparent vacuum packaging layer 11, wherein a self-sealing opening 13 is processed on the transparent vacuum packaging layer 11, then the transparent vacuum packaging layer 11 is hermetically connected with the second extending part 19, and the one-way air suction valve 18 and the air and water suction dual-purpose interface 17 are in threaded connection; the sealed connection of the transparent vacuum packaging layer 11 to the medical fluid storage bag 1 is then performed. The self-sealing 13 is opened, and the waterproof and breathable laminated non-woven fabric bag 15 containing the heating layer 16 can be adhered to the side surface of the liquid medicine storage bag 1 by means of the magic tape. A three-way pipe 12 can be arranged on the waterproof breathable laminated non-woven fabric bag 15, then solid self-heating materials are added to form a heating layer, and the waterproof breathable laminated non-woven fabric bag is assembled after being sealed. The opening of the vertical section of tee 12 is then closed with rubber stopper 121 and self-sealing 13 is closed. At this time, the air valve cover 185 is opened, the one-way air suction valve 18 is communicated with the air suction cylinder for air suction, and the air can be allowed to be discharged outwards by virtue of the movement of the T-shaped rubber pad 184, when the air suction cylinder is removed after air suction is finished, the thin tube 182 can be automatically sealed, so that the self-reaction of solid self-heating materials in the heating layer 16 caused by the existence of air or water vapor and the like in the transparent vacuum packaging layer 11 when the solid self-heating materials are not needed is avoided. The air valve cover 185 is then fastened.

After air exhaust is completed, liquid medicine filling can be carried out. When the liquid medicine is filled, the cover plate 26 can be opened for filling, and the cover plate 26 is tightly covered by the elastic card 28 and the clamping seat 27 after the filling is finished. The flat squeeze bag 32 can be placed separately without being installed. When the self-heating Chinese medicine liquid bag is not needed to be used immediately, the self-heating Chinese medicine liquid bag can be placed in a cold storage device such as a refrigerator, and the flat water squeezing bag 32 can be placed independently without installation, so that the water in the flat water squeezing bag 32 is prevented from being frozen, and an additional temperature rise program is needed.

When the medicine liquid needs to be heated and taken, the flat water squeezing bag 32 is installed by the round hair patch 3 and the stabbing hair patch 31. Opening the self-seal 13 is to allow gas to enter the transparent packaging layer, removing the rubber stopper 121, and sleeving the end of the vertical part of the tee 12 with the second hose 14；Removing the one-way suction valve 18; the sealing cap 431 is opened, and the water injection connector 43 is inserted into the dual-purpose connector for air suction and water inletThe port 17 is provided with a hole for allowing the end part of the water injection connector 43 to enter the annular snap ring 171, the rubber sealing gasket 172 is squeezed to form a gap with the inner wall of the air-extracting and water-feeding dual-purpose connector 17 to facilitate water entering, then the knob 46 is rotated to drive the sealing plug 47 to move through the threaded rod 45 to eliminate the blockage of the transition connector 41, then the flat water squeezing bag 32 is squeezed, water enters the waterproof breathable film-coated non-woven bag 15 to contact with the solid self-heating material in the heating layer 16, the water injection connector 43 is pulled out after water adding is finished, the connection between the round hair sticker 3 and the thorn hair sticker 31 is torn, and the flat water squeezing bag 32.

At this time, water enters the waterproof breathable composite film non-woven fabric bag 15 and contacts with a solid self-heating material in the heating layer 16, such as calcium oxide or reduced iron powder, wood powder, activated carbon and salt mixture, and oxygen in the air can also enter through the waterproof breathable composite film non-woven fabric bag 15, so that the waterproof breathable composite film non-woven fabric bag is suitable for the exothermic reaction of calcium oxide and the like with water and the exothermic reaction of iron powder by oxidation. During the exothermic reaction, the temperature rise may form water vapor, and some exothermic reactions may form other gases, but all at a certain temperature, which may perform a secondary heating function through the second hose 14. Of course, the solid self-heating material is not limited to calcium oxide or reduced iron powder, wood powder, activated carbon, salt mixture.

The dual-purpose interface 25 for liquid adding and heat dissipation can be opened in the heating process, so that the overlarge steam pressure in the liquid medicine heating process is avoided; after the temperature is raised, the waterproof breathable composite film non-woven fabric bag 15 can be torn off, and the solid self-heating material in the heating layer 16 can be used as a reaction reagent to be recycled for other purposes. The dual-purpose interface 25 can be closed for drinking or use in divided dose by means of the suction nozzle 21 or the transparent screw cover 23.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
