Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and particularly to a moisturizing sodium hyaluronate dressing patch. Background Art

[0002] In the fields of clinical treatment and skin care, moisturizing dressing patches have gradually become an important nursing method due to their high-efficiency moisturizing and repair characteristics. Sodium hyaluronate, as a high-molecular polysaccharide naturally present in human tissues, has excellent water retention ability, can effectively lock in moisture, and provide long-term moisturizing effects for the skin. In recent years, with the in-depth research on skin barrier repair and moisturizing needs, sodium hyaluronate has been widely used in the design of medical dressing patches due to its non-toxic, non-irritating, and good biocompatibility characteristics.

[0003] The main function of the moisturizing sodium hyaluronate dressing patch is to help the skin maintain a moist environment through its core component sodium hyaluronate, promote the repair of the skin barrier function, reduce water loss, and relieve discomfort symptoms such as dryness and peeling. This kind of dressing patch is not only applicable to postoperative wound care, but also widely used in cases where the skin barrier is damaged, such as sensitive skin, eczema, dermatitis, etc.

[0004] Existing dressing patches generally have the phenomenon of adhering to the skin surface over a large area during use. This design method not only lacks skin comfort such as breathability, but also has significant problems during skin dynamic deformation. When the skin expands or contracts, the elastic deformation of the skin will cause cumulative stress at the contact area between the dressing patch and the skin. The continuous action of the cumulative stress will cause relative movement at the adhesion interface between the dressing patch and the skin, ultimately leading to adhesion failure. More seriously, during the repeated expansion and contraction of the skin, the adhesion area of the dressing patch will experience multiple adhesion-detachment cycles. This process not only reduces the use effect of the dressing patch, but also causes additional damage to the skin barrier, and ultimately causes the dressing patch in this area to permanently lose its adhesion ability to the skin due to impurities such as dust or skin debris, thus affecting the treatment effect of the dressing. Summary of the Invention

[0005] In order to overcome the above-mentioned drawbacks, the present invention provides a moisturizing sodium hyaluronate dressing patch.

[0006] The technical implementation solution of the present invention is as follows: A moisturizing sodium hyaluronate dressing patch includes a protective patch, a moisturizing dressing is provided on the protective patch, and a buffer unit is provided on the protective patch; the buffer unit includes a first adhesive strip, the first adhesive strip is fixedly connected to the protective patch, a second adhesive strip and a third adhesive strip are fixedly connected to the protective patch, an external groove is provided outside the protective patch near the third adhesive strip, the protective patch, the second adhesive strip and the third adhesive strip together form an intermediate groove, the protective patch, the first adhesive strip and the second adhesive strip together form an internal groove, through holes are uniformly distributed on the protective patch, and the external groove, the intermediate groove and the internal groove are all communicated with the through holes on the protective patch.

[0007] More preferably, the first adhesive strip, the second adhesive strip and the third adhesive strip are integrally in a quasi-circular ring shape.

[0008] More preferably, the first adhesive strip, the second adhesive strip and the third adhesive strip are each composed of a plurality of S-shaped adhesive strips joined together, and are integrally in a "wavy" shape of a circular ring.

[0009] More preferably, the cross-sectional area of the intermediate groove is larger than the cross-sectional area of the internal groove.

[0010] More preferably, it further includes a protective sheet, the protective sheet is composed of an outer ring part, a middle ring part and a cylindrical part, the outer ring part of the protective sheet is adhered to the side of the protective patch away from the moisturizing dressing by an adhesive, and the middle ring part of the protective sheet is made of a breathable and dust-proof material.

[0011] More preferably, a liquid storage cavity is formed between the protective sheet and the protective patch, and a plugging block is fixedly connected to the protective sheet.

[0012] More preferably, the liquid storage cavity and the moisturizing dressing are respectively located on both sides of the protective patch, and the cross-sectional area of the liquid storage cavity is equal to the cross-sectional area of the moisturizing dressing.

[0013] More preferably, the through holes on the protective patch are all frustum-shaped, and the side with the larger diameter faces the protective sheet.

[0014] More preferably, several through holes on the protective patch are respectively distributed near the "wavy grooves" of the first adhesive strip, the second adhesive strip and the third adhesive strip. The first adhesive strip, the second adhesive strip and the third adhesive strip each wrap the adjacent through holes on the protective patch in a mostly surrounding manner, and the cross-sectional area of the through holes on the protective patch gradually decreases from the direction away from its axis to the direction close to its axis.

[0015] More preferably, the protective sheet is provided with a protruding part.

[0016] The beneficial effects of the present invention are as follows: In the present invention, the first adhesive strip, the second adhesive strip, and the third adhesive strip are set as a circular "wave" shape formed by splicing a number of S-shaped adhesive strips. The bending structure of the S-shaped adhesive strip can disperse the stress generated by skin stretching and contraction, avoiding local stress concentration. Moreover, the protective patches on the upper sides of the outer groove, the middle groove, and the inner groove are not rigidly fixed to the skin. Thus, when the skin deforms dynamically, the skin within the ranges of the outer groove, the middle groove, and the inner groove can freely contract (causing wrinkles to appear on some of the protective patches on the upper sides of the outer groove, the middle groove, and the inner groove), and this force will not be rigidly transmitted to the first adhesive strip, the second adhesive strip, and the third adhesive strip, reducing the cumulative stress generated by the skin deformation on the overall adhesive strip, thereby reducing the probability of detachment between the skin and the adhesive strip during dynamic skin deformation; Alcohol is stored in the liquid storage cavity and released when the protective patch needs to be torn off, reducing the adhesion force between the protective patch and the skin, thereby reducing the probability of the dressing sticking to the patient's skin and improving the comfort level of the patient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Embodiment 1

[0021] The present embodiment discloses a moisturizing sodium hyaluronate dressing patch for skin injury repair.

[0022] As Figures 1-5 shown, the dressing patch includes a protective patch 1 made of medical non-woven fabric. A moisturizing dressing 2 is provided on the protective patch 1. The component of the moisturizing dressing 2 is sodium hyaluronate, which has excellent moisturizing, anti-aging, repair and lubrication functions. A buffer unit is provided on the protective patch 1. The buffer unit includes a first adhesive strip 3 fixedly connected to the protective patch 1. A second adhesive strip 4 and a third adhesive strip 5 are fixedly connected to the protective patch 1. The first adhesive strip 3, the second adhesive strip 4 and the third adhesive strip 5 are all made of medical pressure-sensitive adhesive, and there is a protective film on their bottom surfaces to prevent accidental adhesion. The widths of the three increase in sequence. The first adhesive strip 3, the second adhesive strip 4 and the third adhesive strip 5 are integrally in a quasi-circular ring shape and are all composed of several S-shaped adhesive strips assembled together, presenting a "wavy" shape of the circular ring as a whole. The bending structure of the S-shaped adhesive strip can disperse the stress generated by skin stretching and contraction, avoid local stress concentration, reduce the fatigue of the adhesive layer, and the circuitous shape of the S-shaped adhesive strip is more adaptable to the multi-directional movement of the skin. Through the elastic deformation of the S-shaped adhesive strip, the situation of separation from the skin is reduced, and the curved edge can disperse the stress and reduce the risk of local peeling. The "wavy" shape of the circular ring presented by the first adhesive strip 3, the second adhesive strip 4 and the third adhesive strip 5 as a whole can evenly disperse the stress along the circular path, avoid local stress concentration, and can adapt to the multi-directional stretching / contraction of the skin. The force in each direction is balanced. The circular closed structure has no clear directionality and can be evenly adjusted with the deformation of the skin in any direction. The elastic deformation ability of the S-shaped adhesive strip is superimposed on the self-adaptability of the circular ring, significantly reducing the peeling risk at the adhesion site. An external groove 6 is provided on the outside of the protective patch 1 near the third adhesive strip 5. The protective patch 1, the second adhesive strip 4 and the third adhesive strip 5 together form an intermediate groove 7. The protective patch 1, the first adhesive strip 3 and the second adhesive strip 4 together form an internal groove 8. The protective patch 1 is provided with uniformly distributed through holes. The external groove 6, the intermediate groove 7 and the internal groove 8 are all communicated with the through holes on the protective patch 1. After the dressing patch adheres to the skin, the intermediate groove 7 and the internal groove 8 can only exchange air with the outside through the through holes on the protective patch 1, so as to dissipate heat from the patient's skin. There is no rigid fixation with the skin at the corresponding external groove 6, intermediate groove 7 and internal groove 8 of the protective patch 1. Thus, when the skin stretches or contracts, the skin within the range of the external groove 6, intermediate groove 7 and internal groove 8 can freely contract (causing wrinkles to appear on the part of the protective patch 1 above the external groove 6, intermediate groove 7 and internal groove 8), and this force will not be rigidly transmitted to the first adhesive strip 3, the second adhesive strip 4 and the third adhesive strip 5, reducing the cumulative stress generated by skin deformation on the overall adhesive strip. The cross-sectional area of the intermediate groove 7 is larger than that of the internal groove 8, that is, the fastening force of the protective patch 1 on the skin decreases with the increase of the distance from the moisturizing dressing 2, thereby improving the comfort of the patient.

[0023] In this embodiment, the usage process of the moisturizing sodium hyaluronate dressing patch is as follows: Preparation step: Clean and disinfect the skin near the area where the patient needs to apply the moisturizing sodium hyaluronate dressing patch (hereinafter referred to as the dressing patch).

[0024] Attachment step: Fold the dressing patch upward circumferentially, and gradually tear off the protective films on the first adhesive strip 3, the second adhesive strip 4, and the third adhesive strip 5 one by one. Then, align the moisturizing dressing 2 with the affected area of the patient, and gradually lower the protective patch 1 from the center to the outside. The first adhesive strip 3, the second adhesive strip 4, and the third adhesive strip 5 are successively attached to the skin in sequence, and are gradually pressed from the center to the outside until the attachment is completed.

[0025] Embodiment 2

[0026] A moisturizing sodium hyaluronate dressing patch disclosed in this embodiment, on the basis of Embodiment 1, also has the function of being easy to tear off from the skin without damaging the skin.

[0027] As Figures 1-7 shown, it further includes a protective sheet 9. The protective sheet 9 is composed of an outer ring part, a middle ring part, and a cylindrical part. The outer ring part of the protective sheet 9 is adhered to the side of the protective patch 1 away from the moisturizing dressing 2 through an adhesive. Only the outer ring part of the protective sheet 9 is adhered to the protective patch 1, which is convenient for tearing off. Moreover, the middle ring part of the protective sheet 9 is made of a breathable and dust-proof material, and the cylindrical part of the protective sheet 9 is made of a soft light-shielding and waterproof material (such as dark soft plastic, etc.). A liquid storage cavity 10 is formed between the cylindrical part of the protective sheet 9 and the protective patch 1. When not in use, the protective sheet 9 is close to the upper side of the protective patch 1 (that is, the protective sheet 9 is in a tightened state). When in use, alcohol is stored in the liquid storage cavity 10, and the liquid storage cavity 10 is located above the moisturizing dressing 2, and the cross-sectional area of the liquid storage cavity 10 is equal to the cross-sectional area of the moisturizing dressing 2, so as to assist the moisturizing dressing 2 in dissipating heat to improve the cold compress effect of the moisturizing dressing 2. A blocking block 11 is fixedly connected to the protective sheet 9. The blocking block 11 is made of rubber and is used for allowing a needle to pass through to inject medical alcohol into the liquid storage cavity 10. The through holes on the protective patch 1 are all frustum-shaped, and the side with the larger diameter faces the protective sheet 9, which is used to improve the efficiency of alcohol passing through the through holes on the protective patch 1. Several through holes on the protective patch 1 are respectively distributed near the "wavy grooves" of the first adhesive strip 3, the second adhesive strip 4, and the third adhesive strip 5. The first adhesive strip 3, the second adhesive strip 4, and the third adhesive strip 5 all wrap the adjacent through holes on the protective patch 1 in a mostly surrounding manner, so as to Figure 6Taking the third adhesive strip 5 as an example, alcohol is allowed to pass through the through-holes on the protective patch 1 and accumulate near the "grooves" of the third adhesive strip 5, thereby slowing down the diffusion rate of alcohol on the patient's skin and enabling the alcohol to come into full contact with the third adhesive strip 5, thus accelerating the detachment of the third adhesive strip 5. Moreover, the cross-sectional area of the through-holes on the protective patch 1 gradually decreases from a direction away from its axis to a direction closer to its axis, so that the alcohol is more reasonably distributed (the amount of alcohol gradually increases from the inside to the outside), and the fastening of the protective patch 1 gradually loosens from the outside to the inside. There is a protrusion 12 on the protective sheet 9, which does not contact the protective patch 1 here, facilitating the tearing off of the protective sheet 9.

[0028] In this embodiment, the usage process of the moisturizing sodium hyaluronate dressing patch is as follows: Preparation process: Prepare medical alcohol and a syringe. Pass the syringe through the protective sheet 9 and inject medical alcohol into the liquid storage cavity 10 until the protective sheet 9 expands as Figure 4 shown, then stop injecting and pull out the syringe.

[0029] Tearing-off step: Taking the third adhesive strip 5 as an example, ensure that the protective patch 1 is in a horizontal state. Tear off the protective sheet 9 from the protective patch 1 through the protrusion 12. The medical alcohol stored in the liquid storage cavity 10 diffuses circumferentially and flows downward through the through-holes on the protective patch 1 into the outer groove 6, the middle groove 7, and the inner groove 8. After the alcohol enters the outer groove 6, the middle groove 7, and the inner groove 8, it mostly accumulates near the "grooves" of the third adhesive strip 5. The alcohol dissolves part of the colloid and disinfects the skin, so that the adhesion between the third adhesive strip 5 and the skin gradually loses. Also, since the alcohol distribution gradually increases from the inside to the outside, the protective patch 1 gradually loses its adhesive force from the outside to the inside. After a period of time (that is, after the patient feels that the adhesion force of the dressing patch to the skin decreases), gradually uncover the protective patch 1 from the outside to the inside. Store the alcohol in the liquid storage cavity 10 and release the alcohol when the protective patch 1 needs to be torn off, reducing the adhesion force between the protective patch 1 and the skin, thereby reducing the probability of the dressing patch sticking to the patient's skin and improving the comfort level of the patient.

[0030] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
