The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 and FIG. 2 , a blood transfusion pressurizing device in this embodiment includes a pressurizing bag 1, the side wall of the pressurizing bag 1 is a hollow air bag 3, and the pressurizing bag 1 is used for placing a blood transfusion bag, and the blood transfusion bag is used for placing the blood transfusion bag. During blood transfusion, the bag is connected to the blood transfusion vessel, the lower end of the pressurizing bag 1 is provided with a pipe hole 2 for the blood transfusion vessel to pass through, and the upper end opening of the pressurizing bag 1 is provided with a fixing belt 4; Both are provided with fixing straps 4, which can be tied together, thereby preventing the blood transfusion bag from slipping out of the upper end when the air bag 3 is inflated, ensuring that the air bag 3 can effectively squeeze the blood transfusion bag, pressurize the blood transfusion bag, and realize pressurized blood transfusion.

There are grooves on both sides of the inner wall of the pressurized bag 1 from top to bottom, and a heating bar 5 is arranged in the groove; the height of the heating bar 5 is equal to the distance between the two heating bars 5, and the inner wall of the pressurized bag 1 The heating strips 5 on one side are alternately arranged with the heating strips 5 on the other side. Specifically, as shown in FIG. 1 , the heating strips on the left inner wall of the pressurized bag 1 and the heating strips on the right inner wall of the pressurized bag 1 are staggered. The blood transfusion bag can be in contact with the heating strip from top to bottom to ensure the uniformity of heating. At the same time, the heating strips arranged at the upper and lower intervals enable the wall of the airbag between the two heating strips to expand and effectively squeeze the blood transfusion bag. Compared with the inner wall of the pressurized bag 1, the heating layer is set. The pressure effect is better, and the uniformity of heating is not affected at the same time.

The heating bar 5 includes a heat conducting bar 6 and a PTC heating element arranged in the heat conducting bar 6 . When the PTC heating element is energized, it generates heat, and the temperature is controllable, and the heat conducting strip 6 can quickly conduct the heat of the PTC heating element to the blood transfusion bag.

Protrusions 7 are evenly distributed on the side of the heat conducting strip 6 facing the blood transfusion bag. In this embodiment, the cross-section of the protrusions 7 is arc-shaped. Since the inner wall of the pressure bag 1 is not an absolute plane during the pressurization process, and the outer wall of the blood transfusion bag is also non-planar, a large number of evenly distributed protrusions 7 can better fit the outer wall of the blood transfusion bag to ensure effective heat conduction.

The fixing belt 4 includes an elastic belt. The fixing belt 4 can be an elastic belt as a whole, or a section of the fixing belt 4 can be an elastic belt. In this embodiment, a section of the fixing belt 4 is an elastic belt. When the fixing belts are tied together, The elastic band can provide a certain margin, so that the pressure bag 1 can be slightly stretched when the pressure is too high, so as to avoid damage to the blood transfusion bag when the pressure is too high or too violent.

In this embodiment, the airbag 3 is connected to the one-way inflatable balloon through the trachea, and the one-way inflatable balloon is in the prior art. Inflating, thereby pressurizing the blood transfusion bag, is convenient to use.

The upper end of the pressure bag 1 is provided with a lanyard 8, which can be suspended for blood transfusion pressure. The outer wall of the pressurized bag 1 is provided with an exhaust valve communicating with the airbag 3. After the pressurization is completed, the exhaust valve can be opened to discharge the gas in the airbag 3 for use in the next pressurization.

The present invention is not limited to the above-mentioned optional embodiments, and anyone can draw other various forms of products under the inspiration of the present invention, but no matter what changes are made in its shape or structure, all fall within the definition of the claims of the present invention. The technical solutions within the scope all fall within the protection scope of the present invention.
