Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a transparent film for visual quantitative evaluation. Background Art

[0002] A PICC is a central venous catheter (CVC), primarily used for patients undergoing chemotherapy for cancer and those requiring long-term intravenous infusions. The catheter is implanted via peripheral venous puncture (i.e., an arm vein) and reaches the body's largest blood vessel, the superior vena cava. It reduces drug irritation to the vascular lining, monitors central venous pressure, and performs enhanced CT and venography imaging. After placement, a sterile transparent film is applied to the area to maintain dryness and cleanliness, and to ensure accurate calibration of the catheter. This allows for easy observation of any bleeding or dislodgement at the puncture site. PICCs can be left in place for up to one year. Patients need to carry the catheter home for an extended period after implantation, and unless there are any local abnormalities, they need to return to the hospital every seven days for replacement of the transparent film.

[0003] Due to temperature, personal sweating, bathing and other reasons, local moisture can easily occur, which will increase the risk of catheter dislocation and cause bacteria to enter the puncture site, resulting in local infection or even systemic infection that is life-threatening. Therefore, it is very necessary to replace the transparent dressing in time. However, due to differences in cultural level and cognitive level, patients have different views and cognitions on the frequency of film replacement, and lack quantitative evaluation indicators to determine whether the film needs to be replaced.

[0004] Therefore, a transparent film with visual quantitative evaluation is needed to improve the above problems. Utility Model Content

Several embodiments of the present invention are provided. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] See also Figure 1-2 , the utility model provides a technical solution:

[0027] Example 1, please refer to Figure 1 、 2 A transparent film for visual quantitative evaluation includes an outer film composed of a transparent outer film 1 and a side film 7. The side film 7 is made of non-woven fabric. One side of the outer film is provided with an adhesive surface, and the adhesive surface is provided with a protective layer 2. A color-changing indicator layer 3 for liquid seepage monitoring is provided in the middle of the adhesive surface of the transparent outer film 1. The color-changing indicator layer 3 includes a liquid-absorbing layer 5, and a color-changing structure for monitoring liquid seepage is provided inside the liquid-absorbing layer 5.

[0028] The color-changing indicator layer 3 is provided to indicate color change when exudation is detected, so that patients or medical staff can visually observe the occurrence of exudation so as to take measures. The amount of wound exudate, the outlet of exudate, the moisture range under the film, the degree of moisture, etc. can be judged, making the identification method for clinical medical staff simpler and more intuitive. The side film 7 is made of non-woven fabric material. The non-woven fabric film can prevent the edge from curling or not sticking during use. The two sides of the side film 7 have protruding side wings, which can be used as auxiliary fixation, and a hole groove is opened in the middle of the side wing on one side for the catheter to pass through, ensuring that the catheter does not shift during use.

[0029] Please refer to Figure 1 、 2 The color-changing structure includes a color-changing indicator portion 6 arranged in the middle of the liquid-absorbing layer 5, and a warning color-changing portion 4 is arranged on the outside of the color-changing indicator portion 6. The color-changing indicator portion 6 and the warning color-changing portion 4 show different colors after absorbing the exudate.

[0030] The setting of the color-changing indicator part 6 monitors the position and amount of exudate, which can meet the daily monitoring needs of medical staff, while the setting of the warning color-changing part 4 has more of a prompting effect, especially for patients. After observing the discoloration of the exudate of different colors, they need to pay attention in time, replace the film and treat the exudate.

[0031] Please refer to Figure 1 、 2 The color-changing indicator portion 6 includes a plurality of indicator strips, which are a plurality of waist-shaped ring strips, and the sizes of the plurality of waist-shaped ring strips gradually increase from the inside to the outside.

[0032] There are several waist-shaped ring strips of different sizes, which can monitor the amount of exudate according to the color change range.

[0033] The warning color changing portion 4 is arranged around the outside of the liquid absorbing layer 5. The warning color changing portion 4 is a color changing silicone ring made of color changing silicone. The color changing indicator portion 6 is made of a mixture of anhydrous copper sulfate and water absorbing grease.

[0034] Color-changing silica gel turns blue after absorbing water and turns pink after being saturated with water. Anhydrous copper sulfate is white and reacts with water to form copper sulfate pentahydrate, which is blue. Therefore, when pink is observed, the warning amount of seepage has been reached and the film needs to be replaced in time and the seepage area needs to be treated.

[0035] In Example 2, the color-changing indicator 6 is arranged inside the liquid-absorbing layer 5 in any one or more forms of line, dot, mesh, and surface.

[0036] In this embodiment, the color-changing indicator 6 can be provided in different forms.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
