Description

Hydrocolloid thumb tack

Technical Field

The utility model belongs to the technical field of traditional chinese medical science's medical instrument, in particular to hydrocolloid press needle of acupuncture press needle technical field.

Background

The pressing needle (i.e. pressing needle set), also known as pressing nail type intradermal needle, can generate continuous and stable stimulation after being buried in an acupoint, continuously dredge the meridian passage, activate blood circulation to dissipate blood stasis, regulate yin and yang balance, promote the ordered circulation of qi and blood of viscera, meridians and collaterals, and stimulate the healthy energy of human body, thereby achieving the effect of dispelling pathogenic factors. The thumb-tack needle is advocated for its advantages of simple operation, safety, no pain, quick action, durable curative effect, convenient movement, and wide adaptation. However, the research and development of the product that the needle body of the thumb-tack needle is directly used for the acupuncture point detoxification and disinfection has not yet been started so far, and particularly, the problem of how to enable the needle body of the thumb-tack needle to continuously and directly perform long-time detoxification and disinfection on the wound surface for 24 hours/day and simultaneously perform acupuncture electrochemical needle embedding treatment is still to be researched and innovated.

In recent years, the knock needle has developed various technical solutions of combined innovation with various other therapeutic means. For example, the chinese utility model patent with publication number CN209827977U discloses a press needle for soothing scar and removing scar, which consists of a press needle tool and a silicone gel patch, wherein the press needle tool is fixed in the silicone gel patch; since the silica gel has a therapeutic effect on scars, the silica gel provides a novel combination therapy for the treatment of scar sequelae under the combined action of the electrochemical effect of the thumb press needle.

However, the above-mentioned press needle still has the following disadvantages: (1) The long-time contact of the silica gel and the skin of a human body does not help wound recovery treatment which needs detumescence, disinfection and absorption of exudate of the wound, absorption of pus in follicular inflammatory papules, chronic pressure sores, phlebitis wounds and pustules, and long-time moisture retention (a closed barrier needs to be formed to avoid wound infection); (2) The silica gel has good electrical insulation performance, and when the silica gel is used together with a press needle tool, the needling electrochemical effect of the press needle tool cannot reach a reasonable and better ideal state; (3) Silica gel non-reticulate bodies have weak abilities to entrap, release healing and therapeutic drugs.

The hydrocolloid dressing is a dressing with a moisturizing function, which is prepared from artificial rubber and hydroxymethyl cellulose sodium with strong hydrophilicity and can be firmly adhered to the skin at the edge of a wound; the water content of the hydrocolloid is low, but the hydrocolloid has strong hygroscopicity, and can swell and expand greatly after absorbing seepage (p 4); after the exudate is absorbed, the hydrophilic particles in the dressing can form a semisolid substance similar to gel, and the semisolid substance is attached to the base of a wound to provide and maintain a wet environment which is favorable for wound healing; the hydrocolloid can be attached to the wound to form a closed wound surface, and the closed healing environment can promote the proliferation of microvascular and the formation of granulation tissue, so that the healing of the wound surface is accelerated; meanwhile, endogenous enzyme contained in the hydrocolloid can promote the dissolution of fibrin, and the closed environment provided by the hydrocolloid dressing is also beneficial to macrophage to remove necrotic tissues, so that the debridement function is played.

However, despite the aforementioned functions, there is still no technical solution and therapeutic apparatus for directly and continuously performing intensive and continuous intervention on the points of inflammation, pus property and accumulation of piled state (such as inflammation, abscess and pain) of folliculitis, acne and wound edema, which has electrochemical effect of acupuncture and is toxic-removing and disinfecting.

In addition, because the network structure of the hydrocolloid layer enables the hydrocolloid layer to have stronger gel loading performance, the hydrocolloid layer can be prepared by pertinently selecting and gel loading related (required) disinfection, treatment and rehabilitation materials (such as disinfection, antibiosis, elements which are helpful for local treatment, rehabilitation and tissue rehabilitation, vitamins, antibiotics and the like) according to treatment requirements; when in use, the materials can work together with hydrocolloid and a needle pressing tool.

The utility model discloses in, because hydrocolloid layer all will have the electric conductivity of certain degree after absorbing wound sepage, consequently hydrocolloid layer is except exerting its self hydrocolloid effect, still is favorable to enlarging the application range that the press needle utensil produced acupuncture electrochemical effect rather than jointly. This is because the electrochemical effect generated by the hydrocolloid press needle of the present invention in use includes not only: the redox reaction effect produced by the handle, needle body, needlepoint of the thumb-tack needle, electrolyte body fluid such as intracellular fluid and extracellular fluid of the skin and skin resistance also comprises: the oxidation-reduction reaction effect is generated between the skin resistor and the hydrocolloid patch stuck with the pressing needle handle part; this makes the effect range of the electrochemical effect of the acupuncture of the hydrocolloid press stud of the present invention cover the entire coverage area of the hydrocolloid patch.

Since some metal materials (such as copper) are in contact with the hydrocolloid layer, strong oxidation reaction occurs, and further, severe (oxidative) discoloration precipitation reaction (untoward) occurs on the contact part of the hydrocolloid layer, and finally, the medical device product has negative effects in application. And noble metals including silver or noble metal alloy materials and noble metal plating layers are not easy to oxidize, so that severe (oxidative) discoloration precipitation reaction can be avoided at the contact part of the hydrocolloid layer and the noble metal plating layers.

Similarly, in order to avoid the discoloration and precipitation reaction of the hydrocolloid layer caused by the substrate layer, in the hydrocolloid snap fastener, the substrate layer is a non-conductive substrate layer. The non-conductive substrate layer can be made of non-conductive materials such as PU, PE and the like.

The hydrocolloid patch 1 comprises a base material layer 11 and a hydrocolloid layer 12 compounded on one side surface of the base material layer 11.

In this embodiment, the hydrocolloid layer 12 exhibits conductivity after absorbing the wound exudate, so the hydrocolloid layer 12 not only exerts its own hydrocolloid action, but also is beneficial to expand the action range of the acupressure needle device 2 and the acupressure needle device that generate the electrochemical acupuncture effect together. This is because the electrochemical effect produced by the hydrocolloid press needle in use includes not only: the redox reaction effect produced by the handle part, needle body, needle point of the knock needle, the electrolyte body fluid such as the intracellular fluid and the extracellular fluid of the skin and the skin resistance also comprises: the oxidation-reduction reaction effect is generated between the skin resistor and the hydrocolloid patch stuck with the pressing needle handle part; this makes the effect range of the electrochemical effect of the acupuncture of the hydrocolloid press stud of the present invention cover the entire coverage area of the hydrocolloid patch.

In addition, the thumb pin tool 2 may be made of stainless steel material or noble metal alloy material, and may have a noble metal plating layer 24 (such as gold plating layer or silver plating layer) disposed on the surface thereof. Silver element on the surface of the press needle tool 2 enables the press needle tool 2 to have better conductivity and a disinfection effect when being contacted with the hydrocolloid layer 12, and when the press needle tool is used for embedding needle therapy, the needle body 21 can not only exert the acupuncture electrochemical effect for therapy, but also directly disinfect main infection points or acupuncture points.

In this embodiment, each needle-pressing device 2 has at least one needle body 21, each needle body 21 has a handle 22 for fixing with the hydrocolloid patch 1, the outer end of the needle body 21 forms a needle tip 23, and the length of the needle tip 23 is generally set between 0.05 mm and 2.5 mm.

In this embodiment, the handle 22 may be directly fixed on the adhesive surface of the hydrocolloid patch 1 as shown in fig. 1, or fixed in the hydrocolloid layer 12; or fixed between the base material layer 11 and the hydrocolloid layer 12 of the hydrocolloid patch 1 as shown in fig. 2, wherein the needle bodies 21 penetrate through the hydrocolloid layer 12; it can also be fixed on the non-adhesive back side of the hydrocolloid patch 1 as shown in fig. 3, where the needle bodies 21 penetrate the hydrocolloid patch 1.

Since the non-conductive substrate layer has no conductivity, in order to facilitate the outward conductive connection of the needle-pressing tool 2 (or the needle-pressing tool 2 and the hydrocolloid layer 12), when the handle 22 is disposed on the adhesive surface of the hydrocolloid patch 1, in the hydrocolloid layer 12 or between the substrate layer 11 and the hydrocolloid layer 12, a hole is formed in the substrate layer 11 through which a portion of the hydrocolloid layer 12 (see fig. 1) or the handle 22 (see fig. 2) is exposed and covered by the conductive adhesive plaster 16 for adhesive connection, and the other side (back side) of the conductive adhesive plaster 16 can be connected by an external (electric acupuncture) electrode plate for the electric acupuncture treatment.

When the handle 22 is disposed on the non-adhesive back side of the hydrocolloid patch 1, the handle 22 is directly secured by the positioning structure 3, which may be a positioning medical adhesive tape 32 having electrical conductivity.

The size of the conductive patch 16 may be larger or equal to or smaller than the size of the hydrocolloid patch 1.

The working principle of the hydrocolloid press stud of this embodiment is:

the needle point 23 of the needle pressing tool 2 is aligned to the treatment position, then the adhesive surface of the hydrocolloid patch 1 is attached to the skin of a human body, the needle body 21 is ensured to be buried into the preset treatment position, the hydrocolloid needle pressing tool can be used for carrying out hydrocolloid needle pressing treatment on 24-hour/day embedded needles, meanwhile, the conductive adhesive plaster 16 is pasted on an electrode plate of an electric acupuncture apparatus and external electric acupuncture treatment is adopted, and the electrochemical effect of acupuncture generated during treatment is shown in figure 23.

Example 2

As shown in fig. 4, the present embodiment is a hydrocolloid snap fastener, which has substantially the same structure as that of embodiment 1, except that: the hydrocolloid patch 1 further comprises a precious metal mesh or grid 13 with a precious metal plating layer between the hydrocolloid layer 12 and the non-conductive substrate layer.

The noble metal mesh or mesh 13 with noble metal plating layer having conductivity does not cause the hydrocolloid layer 12 to change color, and when the hydrocolloid layer 12 has conductivity, it can further enhance the electrochemical effect of the needling of the hydrocolloid press needles.

Certainly, in order to facilitate the precious metal mesh or the mesh 13 with the precious metal coating to be connected with the outside in a conductive manner, the precious metal mesh or the mesh 13 with the precious metal coating is further provided with a conductive connecting buckle 14 penetrating through the non-conductive substrate layer, and the conductive connecting buckle 14 can be connected with the power electrode plate in a sticking manner on the side, opposite to the hydrocolloid adhesive layer 12, of the non-conductive substrate layer so as to provide for the treatment of an external electric needle.

Example 3

As shown in fig. 5, 6, 7 and 8, this embodiment is a hydrocolloid snap fastener having substantially the same structure as that of embodiment 1, except that: the substrate layer 11 is a conductive substrate layer.

The conductive substrate layer can be made of conductive cloth or metal film or noble metal film, when the conductive substrate layer is made of metal material except noble metal, a noble metal plating layer 24 is needed to be arranged on the surface of the conductive substrate layer, or an anti-oxidation layer 14 is arranged between the conductive substrate layer and the hydrocolloid layer (as shown in fig. 5); when the surface of the conductive substrate layer has the noble metal element, the oxidation preventing layer 15 (as shown in fig. 6, 7 or 8) does not need to be disposed between the conductive substrate layer and the hydrocolloid layer 12 to prevent the conductive substrate layer from directly contacting the hydrocolloid layer 12.

Obviously, the oxidation preventing layer 15 itself does not cause the hydrogel layer 12 to discolor, and the oxidation preventing layer 15 may be directly provided on the surface of the conductive substrate layer like a silver plating layer, in which case the oxidation preventing layer 15 needs to have conductivity.

In this embodiment, the oxidation preventing layer 15 is a graphite layer. Graphite not only has excellent conductivity, but also can prevent the conductive substrate layer with metal property from generating negative influence on the hydrocolloid layer.

Example 4

As shown in fig. 6, the present embodiment is a hydrocolloid press needle, which has a structure substantially the same as that of embodiment 3, except that: in this embodiment, the positioning structure 3 is used to fix the needle pressing tool 22 to the hydrocolloid patch 1.

The plastic layer 31 is generally non-conductive, and therefore the size of the plastic layer 31 is required to be smaller than the size of the hydrocolloid patch 1 in order to expose the conductive substrate layer for conductive connection with the electrode pads of the electric acupuncture device.

Example 5

As shown in fig. 7 and 8 and fig. 9 and 10, the hydrocolloid press stud of the present embodiment has substantially the same structure as that of embodiment 1, except that: in this embodiment, the positioning structure 3 is used to fix the needle pressing tool 22 to the hydrocolloid patch 1.

The size of the positioning medical tape (32) may be smaller, equal or larger than the size of the hydrocolloid patch 1, for which the present embodiment does not require anything. The positioning medical tape (32) may or may not be electrically conductive.

Example 6

As shown in fig. 24, the hydrocolloid press stud of this embodiment has substantially the same structure as that of embodiment 5, except that: in this embodiment, the needle pressing tool 22 is directly fixed to the hydrocolloid layer 12 by the positioning medical adhesive tape 32.

In this case, the positioning medical tape 32 is used as a base material layer, and the size of the positioning medical tape 32 is larger than that of the hydrogel layer 12.

Example 7

As shown in fig. 10, 11, 12, 13, 14, 15 and 16, the present embodiment is a hydrocolloid snap fastener having substantially the same structure as in embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4 or embodiment 5 or embodiment 6, except that: the hydrocolloid patch 1 is provided with at least one opening 17 penetrating through two sides of the hydrocolloid patch 1, one end of the opening 17 is communicated with the peripheral edge of the hydrocolloid patch 1, the other end of the opening 17 extends towards the needle pressing device 2, and the part of the hydrocolloid patch 1 between the adjacent openings 17 forms an attaching foot 18.

In this case, the hydrocolloid snap fastener can be used to a body position where mobility is large, such as a joint. After the needle pressing tool is embedded into the acupuncture point of the joint, the attaching feet 18 are respectively adhered to the surrounding area of the joint, so that the needle pressing tool and the hydrocolloid patch are completely fixed on the joint, and the hydrocolloid pressing needle is not easy to fall off under the condition that the joint moves freely.

In this case, the present embodiment does not impose too much requirements on the shape of the hydrocolloid patch 1. The hydrocolloid patch 1 may be provided in any shape, such as circular, oval, rectangular, polygonal or polygonal geometric concave, according to the specific therapeutic needs.

In the present embodiment, the opening 17 may be a linear slit 17a as shown in fig. 10, 11, or 12, or may be a planar notch 17b as shown in fig. 13, 15, or 16. When the opening 17 is the planar notch 17b, the shape of the opening 17 may be triangular, fan-shaped, trapezoidal, rectangular, or the like, and the shape of the opening 17 is not required to be excessive in this embodiment.

The opening 17 can be made by various known techniques, such as: die cutting, shearing, cutting, laser, etching, and the like. Parameters such as the length of the linear gap 17a, the width of the planar notch 17b, the opening size and the like can be specifically set according to specific requirements; and the shape, size and other parameters of each opening 17 may be the same or different on the same hydrocolloid patch 1.

Preferably, as shown in fig. 14, 15 and 16, the end of the opening 17 extending towards the needle-pressing tool is set to be smooth arc-shaped, so that the probability that the hydrocolloid patch 1 is continuously torn towards the needle-pressing tool at the opening 17 is small during the use process, and the needle-pressing tool 2 is prevented from falling off.

In this embodiment, the number of the openings 17 may be one, two or more, and may be specifically set according to the needs of a specific treatment site. When two or more openings 17 are provided, all of the openings 17 are preferably radially distributed around the needle actuation device 2.

As shown in fig. 15 and 16, when the area of the attachment feet 18 between adjacent openings 17 is small, an extended attachment surface 19 may also be provided at the outer end of each attachment foot 18. The sticking performance of the extended sticking surface 19 formed at the outer end of each sticking leg 18 is not affected by the movement of the joint, and the sticking performance of each sticking leg 18 can be further enhanced.

The working principle of the hydrocolloid press stud of this embodiment is:

the needle pressing tool 2 and the hydrocolloid patch 1 are fixed at the treatment position by aligning the needle point 23 of the needle pressing tool 2 with the treatment position (such as a joint), then attaching the adhesive surface of the hydrocolloid patch 1 to the skin of a human body to ensure that the needle body 21 is embedded into the preset treatment position, and finally attaching the attaching feet 18 on the positioning medical adhesive tape (32) 3 to the surrounding area of the treatment position in sequence.

Example 8

As shown in fig. 17, this example is a hydrocolloid press stud that has substantially the same structure as example 7, except that: instead of forming the opening 17 directly in the hydrocolloid patch 1, at least one tear structure 110 is provided for forming an opening 17 through both sides of the hydrocolloid patch 1.

The tear structure 110 includes an intermittent trace 110a on the hydrocolloid patch 1. Before use, the opening 17 is formed in the hydrocolloid patch 1 by tearing the tear structure 110 along the intermittent line 110a, which is the same as in example 5.

As shown in fig. 17, the tear structure 110 may be in the form of a thread, one end of the thread 110 is connected to the peripheral edge of the hydrocolloid patch 1, and the other end extends toward the needle pressing tool, so that when the tear structure 110 is torn, a thread slit 17a is formed in the hydrocolloid patch 1.

In addition, both ends of the linear tear enabling structure 110 may be respectively connected to the peripheral edge of the hydrocolloid patch 1, and when the tear enabling structure 110 is torn, a planar notch 17b is formed in the hydrocolloid patch 1.

Obviously, only the opening 17 or only the tear enabling structure 110 may be provided on the same hydrocolloid patch 1, or both the opening 17 and the tear enabling structure 110 may be provided.

The working principle of the hydrocolloid press needle of the embodiment is as follows:

the needle point 23 of the needle pressing tool 2 is aligned to a treatment position (such as a joint), then the adhesive surface of the hydrocolloid patch 1 is attached to the skin of a human body, the needle body 21 is ensured to be buried into the preset treatment position, the easy-tearing structure 110 on the positioning medical adhesive tape (32) 3 is torn off as required to form the opening 17, then the attaching feet 18 between the adjacent openings 17 are sequentially attached to the peripheral area of the treatment position, and the needle pressing tool and the hydrocolloid patch are fixed at the treatment position.

Example 9

As shown in fig. 12, 13 and 17, this embodiment is a hydrocolloid press stud having substantially the same structure as in embodiment 7 or 8, except that: the opening 17 and/or the tear enabling structure 110 are not only arranged on the hydrocolloid patch 1, but also on the positioning medical tape (32) 3, an opening and/or a tear enabling structure corresponding to the opening 17 and/or the tear enabling structure 110 on the hydrocolloid patch 1 is arranged.

Obviously, the opening 17 and/or the tear structure 110 of the hydrocolloid patch 1 are only disposed around the area where the thumb-tack device 2 is located, and do not extend to the area of the hydrocolloid patch 1 where the thumb-tack device 2 is located.

Example 10

As shown in fig. 18, the present embodiment is a hydrocolloid snap fastener having substantially the same structure as any one of embodiments 1 to 9 except that: the back of the hydrocolloid patch 1 is also provided with a transfer release film 4.

The adhesive force between the transfer release film 4 and the hydrocolloid patch 1 is large (larger than the adhesive force between the hydrocolloid patch 1 and the adhesive tape press needle fixing position 5), and the hydrocolloid patch 1 can be removed from the adhesive tape press needle fixing position 5. Meanwhile, the adhesive force of the hydrocolloid patch 1 must be greater than the adhesive capacity of the transfer release film 4 to ensure that the transfer release film 4 can be smoothly taken down from the hydrocolloid patch 1 after the hydrocolloid press needle is attached to the skin of a human body.

Of course, as shown in fig. 19 and 20, providing a light peeling release layer 6 on the surface of the tape press needle fixing site 5 is more advantageous for the separation of the hydrocolloid patch 1 from the tape press needle fixing site 5.

In this embodiment, the light-peeling release layer 6 may be a silicone non-stick or micro-stick layer 61 directly coated on the surface of the tape press pin fixing site 5, or a release film 62, one side of the release film 62 is firmly adhered to the tape press pin fixing site 5 due to its strong adhesion force, and the other side is coated with the silicone non-stick or micro-stick layer 61; thereby ensuring that the product can be easily peeled off the adhesive tape press needle fixing position 5 or the release film 62 in use.

This kind of transfer makes hydrocolloid press stud after leaving sticky tape press stud fixed position 5 from type membrane 4's the mode of setting up, and its edge can not take place any and curl, and this just makes the utility model discloses a hydrocolloid press stud can have thinner comfortable skin paste effect and with bigger area, and after laminating hydrocolloid press stud on human skin, can effectively laminate, ensures treatment.

As shown in fig. 18, in the present embodiment, the transfer release film 4 includes an adhesive area 41 adhered to the hydrocolloid patch 1, and a non-stick tear hand 42 not adhered to (but adhered to) the hydrocolloid patch 1, and the area of the adhesive area 41 is larger than that of the non-stick tear hand 42. The larger area of adhesive area 41 facilitates removal of the hydrocolloid press stud from the adhesive tape press stud retention location 5 by the transfer release film 4, while the non-stick tear tab 42 facilitates removal of the transfer release film 4 from the hydrocolloid patch 1 after application of the hydrocolloid press stud to the treatment location.

When the back side of the hydrocolloid patch 1 is provided with the positioning medical tape 32, the transfer release film 4 is attached to the back side of the positioning medical tape 32.

In this embodiment, the transfer release film 4 may also be provided with openings and/or easy-to-tear structures corresponding to the openings 17 and/or easy-to-tear structures 110 on the hydrocolloid patch 1 (as shown in fig. 21), or may not be provided with any openings and/or easy-to-tear structures (as shown in fig. 22), as long as it is ensured that the transfer release film 4 can completely cover the hydrocolloid patch.
