Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a dual-cavity sustained-release dressing. Background Technology

[0002] Applying herbal patches is a treatment method guided by the basic theories of Traditional Chinese Medicine (TCM), using herbal preparations applied to the skin, orifices, acupoints, and affected areas. It belongs to the external treatment methods of TCM. Umbilical therapy patches are patches made using existing technology, applied to the navel to exert their therapeutic effects. Combining TCM meridian theory and modern biomedical theory, specific Chinese herbs and extracts are used to achieve good therapeutic effects through application to the navel. The principle of umbilical therapy patches is to influence the body's internal blood circulation, nervous system, and endocrine system through the navel, regulating bodily functions and blood flow, thereby achieving the purposes of treatment, health maintenance, and regulating bodily balance. In TCM, the navel is considered an important convergence point of the body's meridians; by applying umbilical therapy patches, acupoints at the navel can be stimulated. This product is applied to the navel to improve blood circulation, stimulate the function of internal organs, promote metabolism, and improve physical condition. It is characterized by warmth, permeability, and rapid absorption. The materials typically contain substances beneficial to human health, such as herbal extracts and plant oils. When applying the navel patch, simply place it around the navel for convenient and sustained therapeutic effects. Navel patches have many applications in medicine, such as regulating endocrine function, improving sleep quality, relieving fatigue, promoting digestion, and enhancing immunity. They can also be used to treat common ailments such as lower back and abdominal pain, gastrointestinal disorders, and irregular menstruation. For patients with chronic diseases requiring long-term medication, navel patches can serve as an adjunct therapy, reducing drug use and improving treatment effectiveness.

[0003] In summary, the current application of umbilical patches presents the following technical problems: While umbilical patches are used in some pediatric treatments, children's tolerance is low, resulting in relatively low drug concentrations. To achieve a sustained therapeutic effect through umbilical application, medical staff or family members need to replace the patches periodically. Furthermore, children's environments differ from adults' stable environments, making it inconvenient to prepare and replace medications frequently, and increasing the workload for operators. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a dual-cavity sustained-release dressing.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A dual-chamber sustained-release dressing includes a patch portion, a control portion, and a replacement portion. The patch portion includes a lower patch and an upper frame, and the control portion and the replacement portion are located within the lower patch and the upper frame. The patch portion includes a lower ring and an inner ring, the lower ring being connected and engaged with the control portion, and the inner ring being connected and engaged with the replacement portion.

[0007] Furthermore, the control unit includes a central pull rod, a diagonal strap, a fixing strap, and a fixing seat. The upper frame is fixedly connected to the upper side of the lower patch. A lower ring is provided on the lower side of the lower patch near one edge. The upper frame has a central pull rod on the upper front and rear sides corresponding to the lower ring. The central pull rod has a diagonal strap on the upper frame near the lower ring. The diagonal strap slopes downward from the upper side of the upper frame and slides through the upper frame. The central pull rod is fixedly connected to the diagonal strap. A fixing strap is fixedly connected to the upper side of the diagonal strap corresponding to the lower ring. A fixing seat is fixedly connected to the lower side of the fixing strap. The lower ring is fixedly connected to the fixing seat. The height space inside the upper frame is greater than twice the thickness of the lower ring.

[0008] Furthermore, the replacement part includes a side pull rod, a pull strap, and a pull bracket. The upper frame has a hole on the side away from the lower ring. A ring bracket is fixedly connected to the lower side of the hole inside the upper frame. An inner ring is provided on the lower side of the ring bracket. A pull bracket is fixedly connected to the inner ring near the lower ring. Pull straps are fixedly connected to the lower ring on both sides of the pull bracket. The pull straps extend out of the upper frame. A side pull rod is fixedly connected to the pull straps outside the upper frame.

[0009] Furthermore, a plug is slidably connected inside the ring frame, an arc handle is fixedly connected to the plug, and a dome is fixedly connected to the arc handle, which facilitates operator control and avoids accidental touch.

[0010] Furthermore, an inner frame is fixedly connected to the lower attachment near the side tie rod. The inner frame cooperates with the tie rod so that the position of the inner ring corresponds to the position of the lower ring.

[0011] The beneficial effects of this utility model are:

[0012] A dual-chamber sustained-release patch is used by filling the lower and inner rings with medication and using a plug to engage with the ring frame to prevent the medication in the inner ring from taking effect. The lower ring of the patch is aligned with the navel. After a period of application, the middle pull rods on both sides are pulled, which pulls the diagonal straps, causing the diagonal straps and fixing straps to straighten. The fixing straps, through the fixing seat, move the lower ring towards the frame, disengaging it from the navel position. Then, the side pull rods are pulled, causing the inner ring to move to the position of the lower ring, achieving the sustained-release effect of the medication.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
