Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an indwelling needle dressing for the prevention and treatment of phlebitis, which has a drug sustained release function and an observation window. Background Technology

[0002] Indwelling intravenous catheters are widely used because they reduce the pain of repeated punctures. However, they can cause phlebitis due to mechanical, chemical, or drug-induced irritation, as well as infection, manifesting as redness, swelling, pain, and even arteriosclerosis. Existing technologies, such as the indwelling catheter dressing with drug sustained release and an observation window described in Chinese patent document CN222056067U, while reducing the incidence of phlebitis through hydrocolloid dressings, rely on additional structures for fixation and lack active drug intervention.

[0003] As described in Chinese patent document CN220588688U, a novel indwelling needle dressing is provided. The disclosed technical solution involves fixing the adhesive strip above the second body via a connector. When the first body and the second body are on the same horizontal plane, the adhesive strip is located vertically above the hydrocolloid dressing strip. Although this solution facilitates observation of the puncture point, it is prone to causing pressure sores due to pressure.

[0004] As described in Chinese patent document CN111939376A, an indwelling needle dressing with anti-swelling and wound-healing properties and its preparation process are disclosed. The disclosed technical solution allows the infusion point to be exposed by tearing open the adhesive ring. However, it focuses more on reducing swelling and does not include a drug sustained-release design for phlebitis. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a phlebitis prevention and treatment dressing with drug sustained release and observation window, thereby solving the problems mentioned in the background art. This invention achieves a comprehensive improvement in phlebitis prevention, stable fixation of the indwelling needle, and patient comfort through drug sustained release technology, integrated fixation structure, and modular design.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 This utility model provides the following technical solution: a dressing for preventing phlebitis with a drug sustained-release and observation window design for an indwelling needle 8, comprising a front side 11 of a thin film base, a rear side 2 of a thin film base, a circular puncture observation window 3, a frame holding film 4, a bottom anti-adhesive release paper 5, an incision 6, and a drug sustained-release layer 7. The main body of the thin film base is a hydrocolloid dressing with good breathability and moisture absorption. The circular puncture observation window 3 is a sterile PU transparent film coated with pressure-sensitive adhesive, used for limiting, fixing, and observing the indwelling needle 8. The thin film base is separated by the incision 6, and the rear side can be torn off and replaced along the incision 6.

[0022] This indwelling needle patch, through its integrated design including drug sustained release and incision 6, transforms passive protection into active treatment, filling the technological gap in existing patches for the prevention of phlebitis and possessing significant clinical practical value.

[0023] In this embodiment, the drug sustained-release layer 7 is evenly coated on the skin-contacting side of the film base. Its main component is polysulfated mucopolysaccharide cream, which slowly releases the drug through hydrocolloid hygroscopic action, continuously inhibiting the occurrence of phlebitis. The frame film 4 surrounds the base and has a label on its surface for marking the insertion date and nursing records.

[0024] Through drug sustained-release technology, integrated fixation structure and modular design, a comprehensive improvement is achieved in phlebitis prevention, stable fixation of indwelling needles, and patient comfort.

[0025] When using this invention, since the bottom anti-adhesive release paper 5 is longer than the film base, the bottom anti-adhesive release paper 5 can be easily torn off, the circular puncture observation window 3 can be used to fix the indwelling needle 8, the film base can be smoothed out, and the pasting is completed.

[0026] The film baseband uses transparent hydrocolloid dressing, with a circular puncture observation window 3 in the middle coated with medical adhesive, 1.5-2cm in diameter, to facilitate real-time observation of the puncture point. The film baseband is longer than the traditional indwelling needle 8, and is divided into front and back sides by an incision 6 in the middle, with the back side being easy to tear off and replace.

[0027] The frame holding film 44 surrounds the base band and can be peeled off after the previous step is completed; the surface of the frame holding film 4 is provided with a label that can be pasted on the catheter at the rear end of the indwelling needle 8 to mark the insertion date and nursing record.

[0028] In this embodiment, during the use of the indwelling needle 8, the back side 2 of the film base can be torn off and replaced along the incision 6, which can ensure the effectiveness of the drug without affecting the fixation of the indwelling needle 8.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
