[0018] A method for using an automatic frothing device, the method comprising the following steps:

[0019] In the first step, when the present invention is in use, the second base and the box body are rotated by the triangular rotating block so that the second base is perpendicular to the first base, and then the second base is rotated horizontally so that the L-shaped limit block and the second limit block on the second base are located in the same plane as the L-shaped limit block and the second limit block on the first base. It is easy to use, easy to fold when stored, occupies a small volume, and is convenient to carry.

The required 8ml of physiological saline and 1ml of air are added to the sleeve of the second syringe. 1ml of patient blood is sucked into the sleeve of the first syringe. Then, the two ways of the three-way stopcock are respectively assembled, and the other universal cover of the three-way stopcock is covered and fixed.

[0021] The third step is to push the second syringe push rod by hand to push the liquid in the second syringe sleeve into the first syringe sleeve to mix the liquids. The two syringes and the three-way stopcock are respectively engaged in the corresponding first limit block, L-shaped limit block and second limit block. While inserting them, use the push block to push the slider to engage the pressing end of the first syringe push rod into the concave block and fix them with fixing buckles.

[0023] In the fifth step, the motor is electrically connected to the battery in the battery box. The motor is externally connected to a controller that can adjust the speed of the motor. When the power switch of the motor is turned on, the motor rotates so that the first bevel gear drives the second bevel gear to rotate, so that the rotating column rotates, thereby rotating the first threaded column, the adjusting sleeve and the second threaded column, so that the connecting column pushes the slider to move back and forth, thereby realizing the push and pull of the first syringe push rod in the first syringe sleeve.

[0024] In the sixth step, when the first syringe push rod squeezes the liquid in the first syringe sleeve into the second syringe sleeve, the second syringe push rod pushes the push block upward, so that the second connecting rod and the sliding connecting plate move upward, and the pull rope has two tension springs. When the first syringe push rod is drawn in the direction of the first syringe push rod, the two tension springs generate tension to make the push block push the second syringe push rod, so that the liquid in the second syringe sleeve can enter the first syringe sleeve. This reciprocating process realizes automatic foaming. After completion, the motor power is turned off. There is no need for manual foaming, which saves manpower and time and avoids uneven foaming. At the same time, the connection between the first syringe sleeve and the second syringe sleeve and the three-way stopcock is stable and will not fall during foaming, which reduces the possibility of work errors and improves work efficiency.

It is easy to use, easy to fold when stored, small in size, and convenient to carry;

[0027] 2. The present invention is provided with a push-pull mechanism, which adjusts the length of the first threaded column, the adjusting sleeve and the second threaded column by rotating the adjusting sleeve to control the sliding length of the slider on the first slide rail. The length of the first threaded column, the adjusting sleeve and the second threaded column cannot exceed the pushing length of the first syringe push rod in the first syringe sleeve, which is convenient for controlling the push-pull length and convenient for operation. The motor is externally connected to a controller, which can adjust the speed of the motor. When the power switch of the motor is turned on, the motor rotates so that the first bevel gear drives the second bevel gear to rotate, so that the rotating column rotates, thereby rotating the first threaded column, the adjusting sleeve and the second threaded column, so that the connecting column pushes the slider to make a reciprocating motion, thereby realizing the push-pull of the first syringe push rod in the first syringe sleeve, without the need for manual foaming, saving operation time and manpower;

[0028] 3. The present invention is provided with a rebound mechanism. When the first syringe push rod squeezes the liquid in the first syringe sleeve into the second syringe sleeve, the second syringe push rod pushes the push block upward, so that the second connecting rod and the sliding connecting plate move upward. The pull rope has two tension springs. When the first syringe push rod is drawn in the direction of the first syringe push rod, the two tension springs generate tension to make the push block push the second syringe push rod, so that the liquid in the second syringe sleeve can enter the first syringe sleeve. This reciprocating process realizes automatic foaming, uniform foaming and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] A method for using an automatic frothing device, the method comprising the following steps:

[0056] In the first step, when the present invention is in use, the second base 4 and the box body 17 are rotated by the triangular rotating block 19 so that the second base 4 is perpendicular to the first base 1, and then the second base 4 is rotated horizontally so that the L-shaped limit block 11 and the second limit block 12 on the second base 4 are located in the same plane as the L-shaped limit block 11 and the second limit block 12 on the first base 1. It is easy to use, easy to fold when stored, occupies a small volume, and is easy to carry.

[0058] In the third step, push the second syringe push rod 6 by hand so that the liquid in the second syringe sleeve 7 is pushed into the first syringe sleeve 2 to mix the liquids, and respectively engage the two syringes and the three-way stopcock 8 in the corresponding first limit block 10, L-shaped limit block 11 and second limit block 12, and then use the push block 20 to push the slider 16 to engage the pressing end of the first syringe push rod 3 into the concave block 13, and fix them with the fixing buckles 35.

[0059] The fourth step is to open the circular cover 15 through the handle 14, and rotate the adjusting sleeve 26 to adjust the length of the first threaded column 25, the adjusting sleeve 26 and the second threaded column 27 to control the sliding length of the slider 16 on the first slide rail 22.

[0060] In the fifth step, the motor 32 is electrically connected to the battery in the battery box 36. The motor 32 is externally connected to a controller that can adjust the speed of the motor 32. The power switch of the motor 32 is turned on, and the motor 32 rotates so that the first bevel gear 33 drives the second bevel gear 34 to rotate, so that the rotating column 24 rotates, thereby rotating the first threaded column 25, the adjusting sleeve 26 and the second threaded column 27, so that the connecting column 23 pushes the slider 16 to make a reciprocating motion, thereby realizing the push-pull of the first syringe push rod 3 in the first syringe sleeve 2.

This reciprocating process realizes automatic foaming. After completion, the power supply of the motor 32 is turned off. There is no need for manual foaming, which saves manpower and time and avoids uneven foaming. At the same time, the connection between the first syringe sleeve 2 and the second syringe sleeve 7 and the three-way stopcock 8 is stable and will not fall during foaming, which reduces the possibility of work errors and improves work efficiency.
