Background technique

For patients with acute severe pancreatitis, total gastrectomy, esophagectomy, intestinal fistula, gastrostomy, esophageal chemical burn, and other patients who cannot eat through the mouth, total parenteral nutrition support therapy is required. The way of infusion is to enter the nutrient solution into the patient's body. Because patients need a large amount of nutrient solution, a large-capacity three-liter bag capable of preparing medical solution is required to meet the patient's needs.

The structure of the three-liter bag in the prior art includes a bag body, a liquid distribution inlet pipe connected to the bag body, and a liquid medicine output pipe connected to the bag body to input the liquid medicine. Regulating valve control, while ordinary roller regulating valves cannot accurately control the flow of liquid medicine. The infusion flow is usually determined by the experience of nurses, and the infusion speed cannot be adjusted accurately, which is not conducive to patient treatment.

In addition, the existing three-liter bag of medicinal liquid output tube and the infusion needle tube are connected by a plug joint, and the connection strength of the plug joint is small, and the problem of the infusion needle tube falling off easily occurs during the infusion process.

And the existing three-liter bag can no longer add medicinal liquid to the three-liter bag through the syringe during the infusion process, which makes it very inconvenient to temporarily add medicine to the patient.

Utility model content

In view of this, the purpose of this utility model is to provide a disposable fine-tuning intravenous nutrition infusion bag to solve the problem that the infusion speed of the existing three-liter bag cannot be adjusted accurately, the infusion needle tube is easy to fall off, and the three-liter bag cannot be temporarily added to the three-liter bag during the infusion process. medicine etc.

The utility model discloses a disposable fine-tuning intravenous nutrition infusion bag, which comprises a bag body, which is connected with a liquid distribution input pipe and a medicinal liquid output pipe, and also includes a flow regulator connected with the medicinal liquid output pipe. The liquid outlet end of the device is provided with a first threaded joint for connecting the infusion needle tube.

Further, the bottom of the bag body is provided with a rubber pipe joint with a closed end.

Further, the front end of the liquid distribution input pipe is connected with a liquid distribution needle, the rear end of the liquid distribution needle is provided with an air vent, and the liquid distribution needle is covered with a needle cap.

Further, the liquid distribution input pipe is connected to the bag body through a second threaded joint, and the pipe section connecting the bag body and the second threaded joint is provided with a water stop clamp and a joint sleeve of the second threaded joint.

The beneficial effects of the utility model:

1. The disposable fine-tuning intravenous nutrition infusion bag of the utility model can accurately adjust the infusion flow rate through the flow regulator, and the control accuracy of the infusion flow rate is higher, which can improve the treatment effect of patients.

2. The disposable fine-tuning intravenous nutrition infusion bag of the present invention is connected with the infusion needle tube through the threaded joint, and the thread connection strength is high, which can avoid the problem that the infusion needle tube falls off during the infusion process.

3. The utility model disposable fine-tuning intravenous nutrition infusion bag, the rubber tube joint on the bag body can be connected with the syringe, so that during the infusion process, the syringe can be used to temporarily add medicine to the three-liter bag, which greatly facilitates the patient. Treatment.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in the figure, the disposable fine-tuning type intravenous nutrition infusion bag of this embodiment includes a bag body 1, and the bag body 1 is connected with a liquid distribution input pipe 2 and a medicinal liquid output pipe 3, and also includes a liquid medicine output pipe 3. connected to the flow regulator 4 , the liquid outlet end of the flow regulator 4 is provided with a first threaded joint 5 connected to the infusion needle tube 6 . The front end of the liquid distribution input pipe 2 is connected with a liquid distribution needle 8, and the rear end of the liquid distribution needle 8 is provided with a vent hole 9, and the liquid distribution needle 8 is covered with a needle cap 10, and the liquid distribution process summarizes the bag 1 The air inside can be discharged through the air vent 9, and at the same time, the liquid dispensing needle 8 is sealed by the needle cap 10, which can prevent air from entering the bag body 1 to cause contamination of the bag body and the liquid medicine.

In this embodiment, the disposable fine-tuning intravenous nutrition infusion bag accurately adjusts the infusion flow rate through the flow regulator 4, and the infusion flow rate control accuracy is higher, which can improve the patient's treatment effect; and it is connected to the infusion needle tube 6 through the first threaded joint 5 , the threaded connection has high strength, which can avoid the problem that the infusion needle tube 6 falls off during the infusion process.

As an improvement to this embodiment, the bottom of the bag body 1 is provided with a rubber tube joint 7 with a closed end, and the rubber tube joint 7 can be connected to a syringe, so that during the infusion process, the syringe can be used to temporarily add medicine to the three-liter bag.
