Problems solved by technology

However, when the existing humidifying fluid mainly composed of ε-polylysine is stored in a hot and humid environment (especially during the rainy season in the south), it is easy to produce precipitates, and may cause the humidifying fluid to carry bacteria
If the above hidden dangers cannot be discovered in time, it may lead to medical accidents.

Embodiment 1-9

[0033] The formulas and preparation processes of Examples 1-9 are shown in Table 1, and the specific steps are as follows:

[0034] 1) Weigh other raw materials except ε-polylysine and water into a clean container, then add an appropriate amount of purified water, and stir and dissolve into a uniform solution at room temperature;

[0035] 2) Heat the solution obtained in step 1) to 45°C to 85°C, then add ε-polylysine, and stir to dissolve into a homogeneous solution;

[0036] 3) Add purified water to the solution obtained in step 2) to the required concentration, and then sterilize to obtain a humidified liquid;

[0037] 4) Divide and seal the obtained gas humidified liquid to obtain the finished humidified liquid.

Abstract

The invention discloses a gas humidification liquid and a preparation method thereof. The gas humidification liquid is an aqueous solution containing at least ε-polylysine and sodium dehydroacetate as active ingredients, wherein the concentration of ε-polylysine is 3-60 μg / mL, and the concentration of sodium dehydroacetate is 50 μg / mL. ~440 μg / mL. The preparation method of the gas humidification liquid is as follows: First, dissolve other active ingredients except ε-polylysine in purified water at room temperature, heat up to 45-85°C, add ε-polylysine and stir to dissolve, and then Add purified water to the desired concentration, and sterilize to obtain a humidification solution. The humidifying solution of the present invention has good storage stability and is not easy to produce precipitates; the humidifying solution of the present invention has excellent antibacterial broad spectrum and excellent effect, effectively ensuring that the humidifying solution is not contaminated by bacteria during clinical use; in addition, the preparation method It is simple and fast, the active ingredients are easier to dissolve, and has good clinical value and social significance of popularization and use.

Description

Technical field [0001] The invention discloses a gas humidifying liquid and a preparation method thereof, in particular a high-stability gas humidifying liquid with excellent antibacterial function. The invention belongs to the field of clinical nursing products. Background technique [0002] Oxygen therapy is one of the most commonly used nursing techniques and rescue treatment methods in hospitals. Intensive care unit (ICU) patients are in critical condition and most require frequent or prolonged oxygen inhalation. Due to the low humidity of oxygen itself, long-term oxygen inhalation will cause the patient’s airway dryness, dry and cracked nasal mucosa, and difficulty in coughing up sputum. Therefore, in the process of oxygen therapy, a gas humidifying liquid is needed to humidify the oxygen. In order to prevent dry oxygen from irritating the mucous membrane of the respiratory tract, the comfort of the patient is improved and the effect of oxygen therapy is improved. [0003] G...
