Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxybuprocaine hydrochloride gel technology, and in particular to a fast-acting analgesic film gel patch. Background Technology
[0002] Obucaine hydrochloride is an ester-type local anesthetic. It works by inhibiting sodium ion channels on nerve cell membranes, preventing the influx of sodium ions, thereby blocking the generation and transmission of nerve signals, and ultimately causing local tissues to temporarily lose pain and sensation. It is often used in clinical settings where rapid local analgesia or anesthesia is required.
[0003] Most conventional oxybuprocaine hydrochloride products are in gel form. During use, the oxybuprocaine hydrochloride gel is squeezed from a tubing and manually applied to the patient's pre-operative puncture site or post-operative wound, waiting for it to take effect to achieve pre-operative anesthesia and post-operative analgesia. However, this method of application often results in the gel being loose and unable to solidify after application, lacking protection and easily being wiped or contaminated by patient movement. Furthermore, this application method cannot guarantee uniform application, leading to inconsistent and unstable drug efficacy. Therefore, to address these issues, this application proposes a fast-acting analgesic film gel patch using oxybuprocaine hydrochloride gel, achieving stable solidification, smooth application, and rapid and stable drug dispersion. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0026] Reference Figure 1-3This utility model provides an embodiment of a fast-acting analgesic film gel patch, comprising a main backing layer 1, an inner backing layer 2 disposed on one side of the outer surface of the main backing layer 1, and the two backing layers being fixed together by adhesion. The main backing layer 1 is made of medical non-woven fabric, and the inner backing layer 2 is made of polyester film. Polyester film is soft, and its film shape allows for more stable adhesion to the skin. Polyester film is prone to wrinkling, while the non-woven fabric main backing layer 1 can shape the polyester film, ensuring both the flexibility of the backing layer and preventing wrinkles. The inner backing layer 2 is provided with multiple air pores 5, which ensure the breathability of the polyester film. The non-woven fabric also has good breathability, thus ensuring the breathability of the entire gel patch and preventing stuffiness and heat buildup at the wound site, which could affect the normal healing of the wound. The outer surface of the inner backing layer 2 is provided with... There is a gel matrix layer 3, which is made of oxybuprocaine hydrochloride gel. The gel matrix layer 3 is a water-soluble polymer gel as the matrix, mixed with the functional active ingredients of oxybuprocaine hydrochloride, propylene glycol moisturizer, and azone penetration enhancer to form oxybuprocaine hydrochloride gel. It is adhered to a polyester film to form a stable gel patch structure with a size of 10cm×4cm and a thickness of 1mm. After being applied to the skin surface, it can ensure the comfort of the application, solidify the oxybuprocaine hydrochloride gel, and achieve rapid drug dispersion. It can achieve rapid onset of action in a short time after application, and can achieve rapid anesthesia before surgery (such as puncture surgery) and rapid and stable analgesia after surgery. A release paper layer 4 is set on the outside of the gel matrix layer 3. The release paper layer 4 can stably shield and protect the gel structure, and can play a role in preventing adhesion and maintaining the activity of the gel and preventing contamination.
[0027] A reinforcing strip 7 is fixedly connected to the main backing layer 1. An adhesive layer 8 is provided on the reinforcing strip 7. A release paper layer 9 is provided on the outside of the adhesive layer 8. The reinforcing strip 7 and adhesive layer 8 are arranged in four sets, as shown in the attached figure. Figure 3 As shown, the four sets of reinforcing straps 7 can be rotated and unfolded during use, and then adhered to the patient's skin through the adhesive layer 8. This provides auxiliary fixation for the entire gel patch, ensuring that it will not slip or shift due to patient movement, thus guaranteeing its precise and stable positioning. Positioning sleeves 10 are fixedly connected to both sides of the top of the main backing layer 1, and the four reinforcing straps 7 are correspondingly inserted into two positioning sleeves 10, as shown in the attached diagram. Figure 1 As shown, when not in use, the reinforcing strip 7 can be folded and inserted into the positioning sleeve 10 for storage and positioning. The reinforcing strip 7 and the main backing layer 1 can adopt an integrated structure. For example, during manufacturing, it is only necessary to cut out the corresponding shape and then fold the reinforcing strip 7. The positioning sleeve 10 can be fixed to the top of the main backing layer 1 by adhesive.
[0028] An observation port 6 is provided in the middle of the main backing layer 1. The polyester film is transparent, and the observation port 6 is a gap reserved on the non-woven fabric. Its function is to allow observation of the gel's usage status through the observation port 6.
[0029] Working principle: When using the fast-acting analgesic film gel patch, peel off the release paper layer 4, apply the gel matrix layer 3 to the skin at the wound site, rotate to open the reinforcing band 7, peel off the release paper layer 9, and apply the adhesive layer 8 to the patient's skin to reinforce the entire gel patch. This completes the application of the gel patch, allowing the oxybuprocaine hydrochloride gel to release its effects and relieve pain at the wound site. The same principle can also be used for preoperative local anesthesia, such as before a puncture. It can be applied to the puncture site; after ten minutes, the released effects of oxybuprocaine hydrochloride will block nerve signals in the local tissue at the puncture site, thus achieving anesthesia. After removing the entire gel patch, the puncture can be performed conveniently.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
