Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a novel infusion bag. Background Art
[0002] In clinical practice, when infusing some expensive drugs, chemotherapy drugs, or some drugs with incompatibility or relatively small amounts of drugs, it is usually necessary to use a solution without added drugs to flush the liquid in the infusion line. In the process of unplugging the infusion set and inserting another bag of liquid, the drug may drip onto the hands. If it is chemotherapy drugs, it may cause harm to the nurse's body. After a bag of liquid is infused, there is usually about 1 ml of liquid in the liquid bag that cannot flow into the infusion set. Even if the infusion line is flushed, there is still a small amount of wasted liquid. Patients are usually anxious about whether the drugs can be fully infused into the body and worry about the treatment effect. Therefore, in order to avoid residual liquid in the infusion bag and prevent the residual liquid from dripping due to the plugging and unplugging of the infusion set, a new type of infusion bag is now introduced to improve this.

[0017] As a preferred solution, further, there are clamping holes 11 on the circumference of the rear side of the inner cavity of the connecting bag 3, and rubber clamping balls 12 are symmetrically installed on the upper and lower ends of the rear side of the turntable 7. The rubber clamping balls 12 are clamped with the clamping holes 11, and the position of the turntable 7 can be clamped and fixed through the cooperation between the clamping holes 11 and the rubber clamping balls 12.
[0018] As a preferred solution, further, a rubber sealing ring 13 is provided on the circumference of the outer wall of the turntable 7, and the rubber sealing ring 13 can improve the sealing between the turntable 7 and the connecting bag 3. LED lights 14 are provided on the left and right sides of the outer wall of the connecting seat 5, and the LED lights 14 can facilitate the viewing of the infusion status in a dim environment.
[0019] As a preferred solution, further, the first connecting cavity 9 and the second connecting cavity 10 match each other and are positioned correspondingly.
[0020] As a preferred solution, further, a sealing gasket is provided at the connection between the turntable 7, the handle 8 and the connecting bag 3, which can improve the sealing performance and avoid leakage.
[0021] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific work is as follows.
[0022] Infusion bag 1 is a bag of 0.9% saline or 5% glucose injection, and the liquid volume can be 50ml, 100ml, 250ml, or 500ml, which can be configured with the liquid medicine to be infused; liquid storage bag 4 is a bag of about 20ml of 0.9% saline or 5% glucose injection;
[0023] In clinical practice, the whole can be hung in a suitable position through the hanging hole 6, and the infusion set can be inserted into the infusion interface 2, so that the patient can undergo conventional infusion treatment. When the infusion bag 1 and the infusion set need to be flushed, the handle 8 is turned forcefully, and the handle 8 will drive the turntable 7, the second connecting cavity 10, the rubber card ball 12 and the rubber sealing ring 13 to rotate together. During this process, the rubber card ball 12 will be squeezed and deformed and stuck into the inner cavity of the multiple card holes 11. The mutual clamping between the rubber card ball 12 and the card hole 11 can fix the position of the turntable 7. When the second connecting cavity 10 is rotated to a vertical state and corresponds to the position of the first connecting cavity 9, the liquid storage bag 4 is The liquid will flow through the first connecting cavity 9 and the second connecting cavity 10 and flow into the infusion bag 1 to flush the infusion bag 1 and the infusion set. Considering that the capacity of common infusion sets on the market is about 12ml-15ml, the amount of liquid in the liquid storage bag 4 is about 20ml. In this way, after all the liquid is infused, it can ensure that the pipeline flushing is completed and the flushing effect is achieved, and the patient will not be burdened by the infusion of too much liquid. When the flushing is completed, the handle 8 is turned again. When the second connecting cavity 10 is rotated to the horizontal state and staggered with the position of the first connecting cavity 9, the liquid in the liquid storage bag 4 cannot flow downward. At this time, the infusion bag 1 is sealed to facilitate infusion therapy.
[0024] The device has a simple structure and a reasonable design. Its double-layer design makes it easy to flush the infusion bag and the infusion set. It is not only simple and convenient to operate, but also effectively avoids residual liquid medicine in the infusion bag, prevents waste, and ensures that no residual liquid medicine drips when the infusion set is plugged in and out, providing more convenient working conditions for medical staff. It is flexible to use, highly practical, and suitable for promotion.
