The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

As shown in the figure, a pressure arm-binding infusion medication device includes a binding belt 1, a storage bag 2 is provided on the outside of the binding belt 1, a pipeline through hole 22 is provided at the bottom of the storage bag 2, and a connection port 21 that can be opened and closed is provided at the top, an air bag is placed in the storage bag 2, and an air pump connected to the air bag is connected to the binding belt 1. In this embodiment, when in use, the infusion bag is placed into the storage bag 2 from the connection port 21, and the infusion tube is passed through the pipeline through hole 22, and the connection port 21 is closed; the device is worn on the arm of the infusion recipient through the binding belt 1, and then the air bag is inflated by the air pump to make the air bag bulge. In this process, the air bag slowly squeezes the infusion bag, so that the liquid in the infusion bag can flow into the human body.

Both ends of the binding belt 1 are provided with first mother-and-child Velcro 5 that cooperate with each other, which is convenient for putting on and taking off the arm, and is also convenient for adjusting the binding position according to the thickness of the arm to achieve the most comfortable binding state.

The left and right sides and the bottom of the storage bag 2 are sewn to the binding belt 1, and a first zipper or a second Velcro is provided at the connecting port 21 at the top of the storage bag 2. After the infusion bag is placed in the storage bag 2, the connecting port 21 can be closed to prevent the infusion bag from slipping out of the storage bag 2 due to arbitrary movements of the infusionist during the infusion process.

The binding belt 1 is in the shape of a long strip and is made of nylon.

A placement bag 3 is also provided on the outside of the binding belt 1 , and an air pump is installed in the placement bag 3 . The air bag and the air pump are connected through an air guide tube 4 .

The placement bag 3 is a mesh structure, which is convenient for air flow to flow through and ensures that the air pump can perform inflation work normally.

The left and right sides and the bottom of the placement bag 3 are sewn to the binding belt 1, and a second zipper or a third Velcro is provided at the opening at the top of the placement bag 3. After the air pump is placed in the placement bag 3, the opening at the top of the placement bag 3 can be closed to prevent the infusion recipient from slipping out of the placement bag 3 during movement.

The air pump motor of the air pump is connected to the output end of the microcontroller, and the output end of the microcontroller is also connected to a buzzer alarm, a gear indicator light, and a status indicator light. The input end is connected to a gear selection button, a start-stop switch, and a charging power supply. The microcontroller is also connected to a rechargeable battery. In this embodiment, the control system, that is, the microcontroller, the buzzer alarm, the gear indicator light, the status indicator light, the gear selection button, the start-stop switch, the charging power supply, and the rechargeable battery are all integrated on the air pump. This is a conventional technology that can be mastered by those skilled in the art. Therefore, its specific circuit connection structure and mechanical structure are not repeated here. In this embodiment, a buzzer alarm is integrated on the air pump, and an alarm can be sounded after the liquid is delivered without relying on naked eye observation. It is convenient and safe to use; and the air pump can be taken out for charging after use.

A heating plate is provided in the storage bag 2, and the input end of the heating plate is connected to the output end of the microcontroller. The microcontroller controls the heating and constant temperature of the heating plate, thereby heating the infusion liquid to a suitable temperature for the human body, thereby avoiding the situation where the infusion liquid is too cold and causes the human body to feel cold. In this embodiment, the heating plate is directly placed in the storage bag 2 and attached to one side of the infusion bag.

A fourth Velcro is provided between the middle of the inner front side wall of the storage bag 2 and the front side wall of the airbag. The airbag is fixed to the inner front side wall of the storage bag 2 by the fourth Velcro, ensuring that the airbag is in a relatively stable position during the entire inflation process without moving around or pushing out of the storage bag 2.

The airbag is a sheet-like structure, and the space between the rear side wall of the airbag and the rear side wall of the storage bag 2 is used to place the infusion bag; or the airbag is a ring-shaped columnar structure, and the inner ring in the middle of the airbag is used to insert the infusion bag. In this embodiment, two airbag structures are provided for use with the infusion bag to squeeze the infusion bag.

Of course, the size of the airbag after being inflated can also be set to match the size of the storage bag 2, which can effectively squeeze the infusion bag to make the liquid inside flow out completely.

The storage bag 2 has a size of 12 cm in width and 23 cm in height, which is consistent with the size of a common 250 ml infusion bag.

The working process of this embodiment is as follows:

When in use, the infusion bag is placed into the storage bag 2 from the connection port 21, and the infusion tube is passed through the pipeline through hole 22, and the connection port 21 is closed; the device is worn on the arm of the infusion recipient through the binding belt 1; when the infusion begins, the air pump is started, and the air pump inflates at a slow speed. The volume of the air bag gradually increases under the inflation action of the air pump, thereby squeezing the infusion bag. As the volume of the air bag increases, the liquid inside the infusion bag is squeezed to flow toward the catheter;

When using the device, traditional infusion equipment can be selected, and the air bag extrusion only replaces the gravity extrusion of liquid. The infusion speed is still regulated by the flow regulating valve located in the infusion device. An air pump with adjustable inflation speed can also be used to control the flow speed through the air pump itself. The speed of liquid extrusion inside the infusion bag is controlled according to the regulated inflation speed of the air pump, thereby controlling the speed of infusion liquid drops. When using an air pump with adjustable inflation speed, there is no need to use an infusion device with a flow regulating valve, thereby saving more costs of disposable infusion consumables;

When using an air pump with adjustable inflation speed, set the inflation speed according to the gear selection button integrated on the air pump. For example, it is divided into three gears: low speed, medium speed, and high speed infusion. Set the fixed inflation time corresponding to the three gears according to the different speeds and the 250ml infusion bag capacity. After the air pump is inflated, the buzzer alarm will sound to avoid blood reflux caused by insufficient observation in traditional infusion, and also avoid the nervousness of having to observe the infusion bag all the time during infusion.

In addition, during the infusion process, the liquid in the infusion bag can be heated by a heating plate and the temperature can be set to 37°C, which is close to human body temperature, to avoid the situation where the infusion liquid is too cold and causes the human body to feel cold.

When using this device, since the infusion bag is located closer to the back of the hand for infusion, an overly long infusion tube is not required, and an infusion tube with a length of 30 cm to 50 cm can be selected as needed, saving the cost of disposable infusion consumables.

The device uses disposable infusion equipment and infusion bags, and the other parts can be reused many times. It can be used for daily medical practice and can also be used as war reserve materials.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
