Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nutrient solution infusion set. Background Technology

[0002] Enteral nutrition infusion sets are medical devices primarily used to deliver specially formulated nutritional solutions to the intestines via infusion tubing to meet the nutritional needs of patients. Enteral nutrition infusion sets are used for nutritional support during the recovery period after gastrointestinal surgery, to meet the nutritional needs of patients unable to eat, to treat chronic intestinal diseases, to provide patients with necessary nutrients, and to treat malnutrition, especially when patients cannot adequately absorb oral nutrients.

[0003] Existing infusion sets are prone to clogging when administering nutritional solutions to patients. This is because suspensions containing dietary fiber and homemade homogenized diets are prone to clogging and preventing dripping, making enteral nutrition administration quite challenging. Therefore, we have proposed a nutritional solution infusion set to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a nutrient solution infusion set to solve the problem mentioned in the background art that suspensions containing dietary fiber and homemade homogenized diets are prone to clogging and not dripping, which leads to a rather tricky situation in the infusion of enteral nutrition.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nutrient solution infusion set, including an infusion bag;

[0006] Also includes:

[0007] The first infusion tube is located at the bottom of the infusion bag. A balloon is located at the other end of the first infusion tube, and the infusion bag and the balloon are connected through the first infusion tube. A valve is located on one side of the surface of the balloon and is connected to the inside of the balloon. A second infusion tube is located at the bottom of the balloon and is connected to the inside of the balloon.

[0008] Preferably, the other end of the second infusion tube is connected to a connector, the bottom of the connector is connected to an infusion pump, the bottom of the infusion pump is connected to a third connecting tube, and the other end of the third connecting tube is connected to an infusion nozzle.

[0009] Preferably, a heating sleeve is fitted over the outside of the third connecting pipe.

[0010] Preferably, the infusion bag is fitted over the outside of the mounting rod, and a connecting rod is provided on the upper front side of the mounting rod, with the infusion bag fitted over the outside of the connecting rod.

[0011] Preferably, a mounting bracket is installed on the surface of the mounting rod, the infusion pump is placed on top of the mounting bracket, and the mounting bracket is fixed to the surface of the mounting rod by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By connecting the balloon to the infusion bag, pressure is generated by squeezing the outside of the balloon to make the nutrient solution flow downward, which can reduce the possibility of blockage in the tube. A valve is set on the top of the balloon to inject warm water into the balloon to dilute the nutrient solution and facilitate flushing of the tube, thereby keeping the inside of the tube clean.

[0014] 2. By setting up an infusion pump and heating mantle, the temperature and flow rate of the nutrient solution can be controlled, because the flow rate and temperature are closely related to the patient's intestinal tolerance. Low temperature or fast flow rate can easily cause diarrhea in patients. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] This invention provides a nutrient solution infusion set, which includes an infusion bag 3. The main problem addressed by this invention is that suspensions containing dietary fiber and homemade homogenized diets easily clog the infusion tubing, preventing proper dripping and making enteral nutrition administration a challenging process.

[0021] For the device provided by this utility model, please refer to Figure 1-3 The following is a detailed introduction.

[0022] The first infusion tube 5 is located at the bottom of the infusion bag 3. A balloon 4 is attached to the other end of the first infusion tube 5. Slightly squeezing the balloon 4 increases the pressure inside the tube, causing the nutrient solution to flow rapidly. The infusion bag 3 and the balloon 4 are connected via the first infusion tube 5. A valve 13 is located on one side of the balloon 4, communicating with the inside of the balloon 4. The valve 13 allows warm water to be injected into the balloon 4 to dilute the nutrient solution and facilitates flushing of the tube, keeping it clean. An opening and closing cap is located at the inlet of the valve 13, allowing for... Valve 13 is closed. A second infusion tube 6 is provided at the bottom of balloon 4. The second infusion tube 6 is connected to the inside of balloon 4. The other end of the second infusion tube 6 is connected to connector 8. The bottom of connector 8 is connected to infusion pump 7 to regulate the flow rate of nutrient solution. The bottom of infusion pump 7 is connected to third connecting tube 9. The other end of third connecting tube 9 is connected to infusion nozzle 11. Heating sleeve 10 is provided on the outside of third connecting tube 9. The speed and temperature are closely related to the patient's intestinal tolerance. Low temperature or fast speed can easily cause diarrhea in the patient.

[0023] To further explain, the infusion bag 3 is fitted over the outside of the mounting rod 1. A connecting rod 2 is provided on the upper front side of the mounting rod 1. The infusion bag 3 is fitted over the outside of the connecting rod 2. A fixing bracket 12 is installed on the surface of the mounting rod 1. The infusion pump 7 is placed above the fixing bracket 12. The fixing bracket 12 is fixed to the surface of the mounting rod 1 by bolts. The mounting rod 1 can fix the infusion bag 3. By installing the fixing bracket 12 on the surface of the mounting rod 1, the infusion pump 7 can be placed outside the mounting rod 1. The height of the fixing bracket 12 can be adjusted by tightening the bolts, thereby adjusting the position of the infusion pump 7 as needed.
