The inner cavity 11 for placing the infusion bag 2 is provided inside the outer bag body 1, the inflation mechanism 3 is connected to the outer bag body 1 and is used to fill the inner cavity 11 with gas, and the heating mechanism 4 is detachably connected to the outer bag body 1 and is used to heat the inner cavity 11.

[0030] When the infusion bag 2 is placed in the inner cavity of the outer bag body 1 for infusion, gas can be filled into the inner cavity through the inflation mechanism, and the filled gas pressurizes the infusion bag 2 on the outside of the infusion bag to avoid direct contact between the filled gas and the liquid in the infusion bag, which is safer and can speed up the infusion speed. In a low temperature environment, in order to maintain the patient's body temperature, the infusion bag 2 can be heated by the heating mechanism 4, so that the output liquid is within a suitable temperature range to avoid adverse effects on the patient's body temperature.

[0031] The heated and pressurized infusion bag of this embodiment can selectively pressurize or heat the infusion bag, making the infusion safer and having a wide range of applications, thus providing more possibilities for clinical applications.

[0032] As a preferred embodiment, the heating mechanism 4 is a self-heating body 44, which is arranged on the front and rear sides of the outer bag body 1. The self-heating body 44 can be an existing warming patch, such as Figure 5 As shown, the self-heating body 44 can be attached to the outer circumference or inner circumference of the outer bag body 1 and surround the outside of the infusion bag 2 to uniformly heat the infusion bag 2.

[0033] As a preferred embodiment, Figure 6 As shown, an inner bag layer 131 is provided on the inner side of the outer bag body 1, and an inner storage pocket 13 is formed between the inner bag layer 131 and the inner side of the outer bag body 1, and the heating mechanism 4 is a self-heating body 44, which is placed in the inner storage pocket 13. The inner bag layer 131 can be provided on the front and rear sides of the outer bag body 1 to form two inner storage pockets 13, and the self-heating body 44 can be selectively placed in one or both of the inner storage pockets 13. When heating is not required, the self-heating body 44 can be taken out from the inner storage pocket 13, which is flexible and convenient to use.

[0034] As a preferred embodiment, the inner bag layer 131 is a breathable layer, and the self-heating body 44 generates heat when it meets oxygen, and the inflation mechanism 3 fills air into the inner cavity 11. The breathable layer allows air to pass through the inner bag layer 131 into the inner storage bag 13 to react with the self-heating body 44, causing the self-heating body 44 to release heat.

[0035] The heated and pressurized infusion bag of this embodiment can be a one-side sex toy connected to the outside of the infusion bag 2. Before use, the inner cavity of the outer bag body 1 is sealed and oxygen-free, and the self-heating element 44 is arranged on the inner side of the outer bag body 1. When in use, air is filled into the inner cavity through the inflation mechanism 3. The self-heating element 44 starts to heat up after encountering oxygen to heat the infusion bag.

[0036] As a preferred embodiment, Figure 5 and Figure 6 As shown, a deflation pipe 31 is connected to the outer bag body 1, and the deflation pipe 31 is connected to the inner cavity 11. A switch valve is provided on the deflation pipe 31. By opening the switch valve, the air in the inner cavity can be released through the deflation pipe 31 to reduce the air pressure in the inner cavity. By changing the speed of the air in the inner cavity, the oxygen content in the inner cavity can be regulated, and then the heat release speed of the self-heating body can be adjusted to adjust the heating temperature of the infusion bag by the self-heating body.

[0037] As a preferred embodiment, the heating mechanism 4 is a heating pad 41, and the heating pad 41 is arranged on the front and rear sides of the outer bag body 1. The heating pad 41 surrounds the outside of the infusion bag 2 to uniformly heat the infusion bag.

[0038] like Figure 2 and Figure 3As shown, the heating pad 41 includes a cushion layer 411 and a heating wire layer 412, the heating wire layer 412 is arranged between the two cushion layers 411, and the heating wire layer 412 is arranged in a mesh or serpentine shape so that the heating pad 41 is heated evenly. The cushion layer 411 can be a cloth layer, and the heating pad 41 is connected to the temperature control display 42 and the plug 43 through a wire, and the plug is used to connect to a power source. The temperature control display 42 can adjust the heating intensity of the heating pad 41 so that the temperature of the liquid output by the infusion bag 2 is within a suitable range. It is understandable that the heating pad 41 can also be connected to a battery, and it is more convenient to use when powered by the battery.

[0039] like Figure 1 As shown, the heating pad 41 can be attached to the inner side or the outer side of the outer bag body 1. Specifically, the heating pad 41 can be connected to the outer bag body 1 by gluing, which facilitates the connection of the heating pad 41 to the outer bag body 1.

When the heating function is not needed, the heating pad 41 is convenient to be taken out of the outer storage pocket 12, and the use is more flexible.

[0041] As a preferred embodiment, the inflation mechanism 3 includes an air tube 31 and an air bundle 32. One end of the air tube 31 is connected to the outer bag body 1 and the other end is connected to the air bundle 32. The air bundle 32 inflates the inner cavity through the air tube 31. A regulating valve 33 is provided on the air tube 31. The regulating valve 33 can be a three-way valve. A one-way valve is provided at one end of the air bundle 32 away from the air tube 31. The one-way valve allows gas to enter the air bundle but does not allow gas to flow out of the air bundle. The air bundle 32 is a spherical hollow body with resilience. When the air bundle 32 is pressed, air flows from the air bundle 32 to the inner cavity 11. When released, the air bundle 32 returns to a spherical shape under the action of elasticity and inhales air from the one-way valve.

[0042] Specifically, when the inflation mechanism needs to fill air into the inner cavity, the regulating valve 33 is rotated to connect the air beam 32 with the inner cavity, so that the air beam 32 can fill air into the inner cavity; when it is not necessary to fill air into the inner cavity, the regulating valve 33 is rotated to isolate the air beam 32 from the inner cavity to prevent the gas in the inner cavity from flowing out.

[0043] In addition, the inflation mechanism 3 may also be replaced by an inflation pump instead of the air beam 32 , and the blower fills the gas into the inner cavity through the air pipe 31 .

[0044] As a preferred embodiment, a temperature sensor 8 is provided in the inner cavity 11 of the outer bag body 1, and the temperature sensor 8 is connected to a temperature display 9. The temperature display 9 can be provided on the outer bag body 1 or on the outside of the outer bag body 1. The temperature sensor 8 is used to sense the temperature in the inner cavity 11 of the outer bag body 1 and display the temperature through the temperature display 9, thereby providing a reference for the high and low heating temperature.

[0045] As a preferred embodiment, an inner hook 6 is provided on the inner side of the top of the outer bag body 1, the top of the infusion bag 2 is connected to the inner hook 6, and an outer hook 7 is provided on the outer side of the top of the outer bag body 1.
