Description

Technical Field

[0001] The invention relates to a press pin, in particular to a straight-press press pin. Background Art

[0002] Press needle is a needle shaped like a thumbtack, with a flat handle and a needle body about one to two centimeters long. It is generally used for intradermal acupuncture or ear acupuncture, an auxiliary treatment method of traditional Chinese medicine, embedding needles on acupoints to play the role of acupoint massage, relieve pain, and promote organ blood circulation. According to the needs of the pathology, the needle will act on the corresponding organ at the acupoint.

[0003] At present, the needle handle of the traditional press needle is glued and fixed on the tape or film, and the tape or film is pasted on the release paper. For example: Chinese patent with authorization announcement number: CN205698498U and authorization announcement number: 2016.11.23 discloses a press needle with an embedded molded sheet, and the outer end surface of the needle handle of the needle body is attached with a film, and has a foam plastic sheet, and the foam plastic sheet is provided with a plurality of spaced accommodating holes, and one side of the foam plastic sheet is attached with release paper, and the needle body and the film are placed on the combination of the foam plastic sheet and the release paper, wherein the film is attached to the release paper, and the needle rod of the needle body and the needle tip at the top thereof are accommodated in the accommodating hole of the foam plastic sheet. The press needle has the following defects: (1) When using, the release paper lifting sheet must be peeled off from the foam plastic sheet by hand or tweezers, and then the press needle is aimed at the acupuncture point and the film is pressed down to make the needle tip penetrate the skin, and finally the release paper lifting sheet is torn off. The clinical operation steps are cumbersome; (2) The film is a thin film with a very thin thickness. When the film is peeled off from the release paper, the film is very easy to deform or curl, causing the film to stick together, affecting the normal use of the press needle, and even causing the press needle to be scrapped; (3) Before inserting the press needle into the acupuncture point, if the hand or tweezers shake or shake, the film may accidentally stick to the skin, and the film must be peeled off from the skin before the needle is implanted, which may even cause the press needle to be scrapped; (4) Pressing the film directly with the hand to make the needle tip penetrate the skin can easily cause the press needle to deviate, resulting in the failure of the press needle to accurately penetrate the acupuncture point, affecting the efficacy. Summary of the invention

[0004] The present invention aims to solve the above-mentioned technical problems existing in the prior art press needles, and provides a direct-press press needle that has an ingenious structure, is quick and convenient to operate, can quickly and accurately insert the press needle into the acupuncture point, and has an adhesive substrate that can be quickly applied to the skin to fix the press needle.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a straight-press press needle, comprising a press needle and an adhesive substrate, the press needle comprising a needle body and a needle handle, the needle handle being fixed on the adhesive substrate, the straight-press type or sticking press needle also comprising a blister shell, a push button and release paper, a placement cavity is provided in the blister shell, the inner wall of the placement cavity forms a guide wall, deformation accommodating cavities connected to the placement cavity are provided on both sides of the placement cavity, the push button is located in the placement cavity, and the outer wall surface of the push button is adapted to the limiting guide wall, the top surface of the push button is fixedly connected to the top wall of the placement cavity, the bottom surface of the push button is provided with a glue layer, the release paper is pasted on the glue layer, a through hole is provided on the release paper, the adhesive substrate is located below the release paper, and the part of the adhesive substrate at the corresponding position to the through hole is bonded and fixed to the glue layer through the through hole, and the needle tip of the needle body does not expose the blister shell. The blister shell in the present invention plays the role of packaging and protecting the press needle, and also plays the role of a bracket when in use. When placed on the skin, the press needle can be suspended above the acupuncture point to be punctured, which can avoid the adhesive substrate from sticking to the skin by mistake and is conducive to improving the accuracy of acupuncture. The blister shell is soft and transparent, easy to deform under pressure, and easy to observe. The blister shell can be replaced by other materials; the top surface of the push button in the present invention is fixedly connected to the top wall of the placement cavity, the adhesive substrate is fixed on the push button, and the needle handle is fixed on the adhesive substrate. When taking and placing the press needle, only the blister shell needs to be taken and placed as a whole, which is convenient to use and can effectively avoid deformation or curling of the adhesive substrate causing the adhesive substrate to stick together; the release paper separates the adhesive substrate and the adhesive layer, and the part of the adhesive substrate at the corresponding position of the through hole is bonded and fixed to the adhesive layer through the through hole, reducing the bonding area between the adhesive substrate and the adhesive layer, which can fix the adhesive substrate on the push button and After the adhesive substrate is pasted on the skin and the blister shell is taken away, the adhesive substrate can be quickly separated from the adhesive layer and pasted on the skin to fix the push needle; under the limiting and guiding action of the guide wall, the push button can make a linear motion along the guide wall, so that the push needle can also make a linear motion with the push button, and the push needle will not deviate when piercing the skin (ensuring that the needle body of the push needle vertically pierces the skin acupuncture point), thereby ensuring the accuracy of acupuncture; when the push button is pressed downward, the blister shell around the top wall of the placement cavity will also be pressed downward synchronously to produce deformation, and the pressure will be directly applied to the guide wall, thereby causing the guide wall to also produce deformation and lose its guiding function, and deformation accommodating cavities connected to the placement cavity are provided on both sides of the placement cavity, and the deformation accommodating cavities can accommodate the deformation amount produced by the blister shell around the top wall of the placement cavity, so that the push button can be pressed smoothly while avoiding the guide wall from being deformed due to excessive concentrated force and losing its guiding function for the push button.

[0006] Preferably, the blister shell protrudes upward to form a pressing convex cavity connected to the placement cavity, and the top surface of the push button is fixedly connected to the top wall of the pressing convex cavity. The pressing convex cavity protrudes outside the blister shell for easy pressing.

[0007] Preferably, the push button includes a pressing part and a guide limiting part, the pressing part is fixed on the guide limiting part, a step structure is formed between the pressing part and the guide limiting part, the upper part of the pressing part is located in the pressing convex cavity and matches the inner wall of the pressing convex cavity, the top surface of the pressing part is fixedly connected to the top wall of the pressing convex cavity, the guide limiting part is located in the placement cavity, the outer wall surface of the guide limiting part matches the limiting guide wall, and the rubber layer is located on the bottom surface of the guiding limiting part. A step structure is formed between the pressing part and the guide limiting part, that is, the cross-sectional area of ​​the guiding limiting part is larger than the cross-sectional area of ​​the pressing part, and the cross-sectional area of ​​the pressing part is smaller than the cross-sectional area of ​​the guiding limiting part. When pressed, the force area of ​​the pressing part is small, the force is more concentrated, and it is conducive to the rapid pressing of the pressing part; the guide limiting part plays the role of radial limiting and guiding, ensuring that the pressing part can always move in a straight line along the limiting guide wall when pressed.

[0008] Preferably, the pressing portion and the guiding limiting portion are both cylindrical structures, and the pressing portion and the guiding limiting portion are homogeneous and integral structures, and the pressing portion and the guiding limiting portion are made of EVA foam material.

[0009] Preferably, the cross section of the deformation accommodating cavity is fan-shaped, and the radius of the fan-shaped cavity is larger than the radius of the placement cavity. The cross section of the deformation accommodating cavity is fan-shaped, and the radius of the fan-shaped cavity is larger than the radius of the placement cavity, which has a good force dispersion effect, is not easy to deform and collapse, and has good structural stability.

[0010] Preferably, the top surface of the pressing portion is provided with a color display layer, and the color display layer is fixedly connected to the top wall of the pressing convex cavity. The color display layer can be a coating with pigment or a color sheet with color, and the color display layer plays the role of color display, marking and positioning, making the pressing portion prominent and conspicuous, so as to facilitate the quick positioning of the pressing portion by vision.

[0011] Preferably, an adhesive layer is provided on the surface of the color display layer, and the color display layer is bonded to the top wall of the pressing convex cavity through the adhesive layer.

[0012] Preferably, the outer edge of the lower opening of the blister shell is provided with a flange. The flange is used to bond with the sealing release paper so as to package the push needle; at the same time, the flange can increase the contact area between the blister shell and the skin, which is conducive to improving the placement stability of the blister shell; in addition, the flange can press the skin surface when the push needle is used, activating the pressure-sensitive nerve endings of the skin tissue, thereby relatively reducing the sensitivity of the pain nerve to acupuncture, reducing the pain of acupuncture treatment, and playing a role in avoiding pain.

[0013] Preferably, the part of the flange located on one side of any deformation accommodating cavity extends outward to form a peeling portion, and the peeling portion and the flange are connected by an inclined transition. The peeling portion is used for grasping by hand, so as to facilitate peeling off the blister shell from the sealing release paper; the peeling portion and the flange are connected by an inclined transition, so that a certain gap is left between the peeling portion and the sealing release paper, and the gap forms a peeling opening, so as to facilitate peeling off the blister shell from the sealing release paper by hand.

[0014] Preferably, the bonding substrate is a tape, film, cotton cloth, non-woven fabric, synthetic fiber fabric, plastic film or metal foil with adhesive coated on the bottom surface. The bonding substrate material is not limited to a single layer or a composite layer, and can be insulating or conductive.

[0015] Therefore, the present invention has the following beneficial effects:

[0016] (1) The needle is fixed in the blister shell. The needle can be taken out by simply peeling off the entire blister shell. It is very convenient to take out the needle and can effectively avoid the problem of the tape sticking to itself;

[0017] (2) When in use, the blister shell acts as a support. When placed on the skin, the needle can be suspended above the acupuncture point to be punctured, which can not only prevent the adhesive substrate from accidentally sticking to the skin, but also help improve the accuracy of acupuncture;

[0018] (3) Through the cooperation between the push button and the guide wall, the needle can be quickly buried by pressing the push button, and the needle will not deviate when it is inserted into the skin, thus ensuring the accuracy of acupuncture;

[0019] (4) A glue coating layer is provided on the bottom surface of the push button, and a release paper is pasted on the glue coating layer. A through hole is provided on the release paper, and a portion of the adhesive substrate at a position corresponding to the through hole is bonded and fixed to the glue coating layer through the through hole, thereby reducing the bonding area between the adhesive substrate and the glue coating layer. This allows the adhesive substrate to be fixed on the push button, and after the adhesive substrate is pasted on the skin and the blister is removed, the adhesive substrate can be quickly separated from the glue coating layer and pasted on the skin to fix the push pin, thereby achieving an instant-stick effect, which is very convenient to use;

[0020] (5) Deformation accommodating cavities connected to the placement cavity are provided on both sides of the placement cavity. The deformation accommodating cavities can accommodate the deformation of the blister shell around the top wall of the placement cavity, so that the push button can be pressed smoothly while preventing the guide wall from being deformed due to excessive concentration of force and losing its guiding function for the push button.
