Problems solved by technology

For example, the use of imported anti-fog oil is not only expensive and increases the burden on patients, but also has the problem of short anti-fog duration, which requires repeated anti-fog treatment to prolong the operation time; using hot salt water anti-fog method also requires repeated anti-fog treatment, and excessively high temperature will shorten the service life of the endoscope lens; using povidone-iodine anti-fog method, some patients will be allergic to iodine, and colored iodophors will affect the doctor's awareness of the lesion during the operation to a certain extent. judge

preparation example Construction

[0093] According to a second aspect of the present invention, there is also provided a method for preparing the above-mentioned anti-fog liquid for medical mirrors, comprising the following steps:

[0094] The active agent, slow-release agent, toughening agent and water are mixed in proportion to obtain the anti-fog liquid for medical mirror surface.

[0095] The invention provides a method for preparing the above-mentioned anti-fog liquid for medical mirror surfaces. The preparation method is simple and convenient to operate and is suitable for industrial scale production.

[0096] As an optional embodiment of the present invention, when mixing with stirring, the stirring speed is 15-50r / s, and the stirring time is 10-60min;

[0097] A typical but non-limiting stirring speed is 15r / s, 20r / s, 25r / s, 30r / s, 35r / s, 40r / s, 45r / s or 50r / s, and a typical but non-limiting stirring time is 10min, 12min, 15min, 18min, 20min, 30min, 35min, 38min, 40min, 42min, 45min, 48min, 50min, 52m...

Embodiment approach

[0098] As an optional embodiment of the present invention, the step of standing still is also included after mixing.

[0099] Preferably, the standing time is 1-24h. Typical but non-limiting periods of rest are 1 h, 2 h, 4 h, 5 h, 8 h, 10 h, 12 h, 15 h, 16 h, 18 h, 20 h, 22 h or 24 h.

[0100] According to the third aspect of the present invention, a medical mirror anti-fog film is also provided, which is made of the above-mentioned medical mirror anti-fog liquid or the medical mirror anti-fog liquid prepared by the above-mentioned preparation method of the medical mirror anti-fog liquid.

[0101] In view of the advantages of the above-mentioned medical mirror anti-fog liquid, the medical mirror anti-fog film formed by the medical mirror anti-fog liquid has good toughness and light transmission, and the anti-fog effect is long-lasting, which can meet the needs of most clinical operations .

[0102] According to a fourth aspect of the present invention, there is also provided...

Embodiment 1

Abstract

The invention provides a medical mirror surface antifogging liquid and a preparation method thereof, a medical mirror surface antifogging film and a preparation method thereof, an antifogging method and a medical instrument, and relates to the technical field of mirror surface antifogging. The medical mirror surface antifogging liquid is prepared from an active agent, a sustained-release agent, atoughening agent and water in specific dosages, wherein a biological extracting agent and ethanol are compounded to be used as the toughening agent; polyhydric alcohol is used as the sustained-releaseagent and has a synergistic effect with other components such as the active agent, the prepared medical mirror surface anti-fog liquid has no stimulation effect on a human body and has an excellent anti-fog effect and lasting time, an anti-fog film formed on a medical mirror surface has good toughness, light transmission and anti-fog effect, and the requirements of most clinical operations can bemet. Various raw materials of the medical mirror surface anti-fog liquid are easy to obtain, the production cost is low, and application and popularization are facilitated. The invention further provides the medical mirror surface anti-fog film, the preparation method thereof and an anti-fog method.

Description

technical field [0001] The invention relates to the technical field of mirror anti-fog, in particular to a medical mirror anti-fog liquid and a preparation method thereof, a medical mirror anti-fog film and a preparation method thereof, an anti-fog method and a medical device. Background technique [0002] With the continuous development of clinical medicine, minimally invasive surgery has gradually penetrated into many aspects of clinical, nursing, imaging and laboratory medicine from the perspective of reducing patient harm. The concept of minimally invasive refers to the use of various modern medical devices such as laparoscopes and endoscopes for different organs and related equipment for preoperative diagnosis and surgical treatment. Its advantages are small trauma, light pain, and quick recovery. Among them, the endoscopic imaging of the monitoring system is the key means. However, due to the high temperature in the human body cavity, there is a temperature difference...
