Description

Technical Field

[0001] The utility model relates to the technical field of nutrition bags, in particular to a temperature-controlled intravenous nutrition bag. Background Art

[0002] Disposable intravenous nutrition infusion bags are mainly used for preparing intravenous nutrition solutions in clinical practice. During radiotherapy and chemotherapy, cancer patients have poor appetite, nausea, vomiting and other reactions due to the side effects of radiotherapy and chemotherapy, which affect the patient's eating and cannot meet the body's nutritional needs. Parenteral nutrition is needed to supplement. Disposable intravenous nutrition bags are commonly used in clinical practice. A mixture of amino acids, fat emulsions, glucose, trace elements, etc. is infused into the nutrition bag to achieve parenteral nutrition support. At the same time, chemotherapy patients need to supplement nutrition solutions through veins. However, gastrointestinal reactions are one of the most common adverse reactions for patients undergoing radiotherapy and chemotherapy. After clinical investigation, more than 60% of patients reported that amino acids and fat emulsions infused into transparent packaging nutrition bags induce nausea and vomiting reactions, aggravate their nausea and vomiting reactions, and thus produce fear and boredom, and even refuse to use intravenous nutrition, affecting the nutritional supplement and chemotherapy treatment process.

[0003] During the infusion of nutrient solution, the liquid temperature should be significantly lower than the room temperature, especially in the autumn and winter seasons. The low indoor temperature causes the infusion temperature to be even lower, which can easily have a greater impact on the patient's body temperature, resulting in low local skin temperature, phlebitis, hypothermia, chills, increased heart rate, local vascular spasm, cold limbs, poor infusion, abdominal pain and diarrhea and other adverse reactions. It may even affect the metabolism of drugs in the human body, and tumor patients are more sensitive and are more likely to have the above-mentioned adverse reactions during low-temperature infusion. Relevant studies have shown that increasing the temperature of intravenous infusion fluid to a certain extent, which is closer to the normal temperature of the human body, can effectively reduce phlebitis, vascular spasm, etc. Secondly, clinical nurses usually wait too long when infusing nutrient bags, which reduces work efficiency. Utility Model Content

[0015] Beneficial effects of the utility model:

[0016] 1. This temperature-controlled intravenous nutrition bag is provided with a pressurizer and a filter. The pressurizer is used to converge and pressurize the liquid, thereby improving the stability and pressure of the liquid during delivery and accelerating the infusion process. The infusion process will be greatly improved, and the work efficiency of clinical nurses will be greatly improved. Then, the impurities and particles in the liquid are removed through effective filtration by the filter. A filter element is arranged inside the filter. The filter element is cylindrical, with a closed bottom and a hollow top, to ensure that the liquid must pass through the filter element when passing through the filter element, thereby achieving effective filtration of the liquid. In addition, the cylindrical design of the filter element increases the filtration area, improves the filtration efficiency, and ensures the purity of the liquid during the infusion process. This combination can ensure that the liquid is stable and pure during the infusion process, thereby improving the effect and safety of the treatment and providing patients with a more reliable treatment experience.

[0017] 2. This temperature-controlled intravenous nutrition bag is provided with a temperature control component. The temperature control component wraps the infusion pipeline in a U-shaped position and adapts to its pipe diameter to achieve a tight connection, which effectively prevents the external environment from affecting the temperature of the infusion liquid. The infusion pipeline is wrapped in the U-shaped position of the temperature control component to form an insulating barrier, which reduces the impact of the external temperature on the infusion liquid. At the same time, due to the close connection between the temperature control component and the infusion pipeline, heat loss is reduced, and the temperature stability of the infusion liquid is more effectively maintained. The heating plate is located inside the temperature control component, close to one side of the infusion pipeline. It accurately controls the temperature of the infusion liquid to ensure that it always remains within the ideal temperature range required for medical treatment. By monitoring and adjusting the temperature of the heating plate, the liquid temperature can be kept constant during the infusion process to avoid adverse reactions or effects caused by temperature fluctuations. This is very important for some temperature-sensitive drugs or liquids, ensuring the effectiveness and safety of treatment.

[0018] 3. This temperature-controlled intravenous nutrition bag can be printed with a variety of cartoon patterns on the outer surface of the liquid storage bag. By printing a variety of cartoon patterns, etc., psychological suggestion therapy is used to relieve patients' gastrointestinal reactions such as nausea and vomiting. The cartoon patterns can attract patients' attention and make them pay more attention to the patterns themselves rather than the infusion process itself, which helps to reduce discomfort and anxiety during infusion. For some patients with injection phobia, liquid storage bags printed with cartoon patterns can reduce their fear of the injection process and make them more willing to accept treatment.

[0030] First, the liquid storage bag 7 is hung in an appropriate position through the hanging hole 13, and then the protective cap 1 of the puncture device 2 is opened to connect the nutrient liquid provided from the outside. After these liquids are merged through the liquid inlet pipeline, they enter the filter 6 for effective filtration to ensure the purity of the infusion liquid. Secondly, the liquid filtered by the filter 6 enters the liquid storage bag 7 for storage and is transported to the patient's intravenous injection point through the infusion pipeline 9. At the same time, the temperature control component 10 always controls the temperature of the infusion liquid to ensure that the temperature of the infusion liquid is appropriate, which is beneficial to the patient's comfort and treatment effect. In addition, the transparent edges and scale lines on both sides of the liquid storage bag 7 provide real-time monitoring of the remaining liquid amount and flow rate, which helps medical staff to adjust the infusion speed or replace the liquid storage bag 7 in time, thereby improving the accuracy and safety of the infusion, ensuring that the patient receives adequate nutritional supplements, promoting rehabilitation and treatment progress, making the infusion process more convenient and accurate, and at the same time improving the efficiency of medical operations and the patient's treatment experience.
