Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The drawings are only for purposes of illustration and are only schematic and non-limiting, and certain elements of the drawings may be omitted, enlarged or reduced and do not represent the size of the actual product, so that it may be understood that certain well-known structures, elements and descriptions thereof in the drawings may be omitted for better illustrating the embodiments of the present invention, and the drawings illustrate the drawings and do not represent the orientation of the actual product.

In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The present invention is described in detail with reference to the accompanying drawings. The utility model provides a time needle mouth subsides that discolours, mainly includes the subsides body 5, the lower terminal surface of the subsides body 5 is equipped with pastes the layer, the lower terminal surface demountable installation who pastes the layer has protective layer 3, the up end of the subsides body 5 is the waterproof layer, the up end demountable installation of waterproof layer has sealed subsides 7, the edge and the waterproof layer laminating of sealed subsides 7 form a confined chamber that holds, it establishes discoloration layer 6 to hold the intracavity, discoloration layer 6 is attached on the waterproof layer, discoloration layer 6 discolours with the air contact back, be equipped with on the waterproof layer and compare the card, it is equipped with colour gradual change picture and time comparison table 1 on the card to compare.

The utility model discloses when using, tear protective layer 3, furtherly, protective layer 3 is provided with the tearing piece 4 that is used for tearing protective layer 3, tear pulling-on piece 4 protruding edge of establishing at protective layer 3. The protective layer 3 can be torn off more easily by tearing off the pull tab 4. After the protective layer 3 is torn off, the cotton swab pressed at the needle opening is covered by the paster body 5, the paster body 5 is tightly pasted on the skin around the needle opening, and the paster body 5 provides pressure for the cotton swab to press the needle opening. Furthermore, the shape of the paster body 5 is rectangular, two reinforcing pasters 2 are arranged on two sides of the paster body 5 in the length direction, and the two reinforcing pasters 2 on the two sides of the paster body 5 are symmetrical about the central line of the paster body 5 and are close to the central line of the paster body 5. The cotton swab pole is in between two reinforcement subsides 2 of every side, through reinforcing subsides 2, makes the skin 5 and the skin of cotton swab department more laminate, can provide bigger pressure, provides the effect of pressing. The sealed subsides 7 that set up on the waterproof layer form the confined chamber that holds with the waterproof layer to the protection can not volatilize at the discoloring material that holds in the discoloring layer 6 of intracavity, leads to discoloring layer 6 to become invalid, can't reach and judge the time of pressing with the 6 colours of macroscopic resolution discoloring layer. After the paste body 5 and the cotton swab are fixed, the sealing paste 7 is torn off, and the color changing layer 6 inside is exposed in the air. After the color-changing material in the color-changing layer 6 is volatilized, the color gradually becomes lighter until the color is colorless. The gradation pattern of the color on the chart coincides with the color change of the color changing layer 6, and the degree of color lightening corresponds to the time of the time chart 1, for example, a color segment displayed within the first minute to two minutes, and the like. The pressing time can be known by comparing the color of the color-changing layer 6 with the color gradient diagram. When the pressing time is enough, the paster 5 can be torn off, and the paster 5 and the cotton swab are thrown into the garbage can.

Further, the color changing layer 6 mainly comprises a substrate and a color changing material, wherein the substrate is made of a material capable of absorbing water, and the color changing material is made of volatile fading ink. The color-changing material mainly comprises sodium hydroxide, thymolphthalein, glycerol and distilled water. The color-changing material is sprayed on the substrate, so that a graph with a larger area can be sprayed, and the color change can be observed conveniently. When the sealing sticker 7 is torn off, the matrix is exposed in the air, and the color-changing material in the matrix volatilizes to gradually lighten the color until the color disappears. The fading time is controlled by adjusting the proportion of each component of the color-changing material. For example, volatile fading ink obtained by blending 1.5g of sodium hydroxide, 1.5g of thymolphthalein, 95g of glycerin and 100g of distilled water was used on normal printing paper and faded completely in about 5 minutes. When 1.5g of sodium hydroxide, 3.0g of thymolphthalein, 95g of glycerol and 100g of distilled water are used for proportioning, the obtained volatile fading ink is used on normal printing paper and fades completely in about 15 minutes. The different materials of the substrates and the different capacities of absorbing the color-changing materials can also influence the fading time. The fading time of the ink can be adjusted by using the matrixes made of the same materials and the color-changing materials in different proportions according to the use requirements, and the fading time can also be adjusted by using the matrixes made of different materials and the color-changing materials in the same proportions. Depending on the application, for example, a patient with poor blood coagulation, the compression time is longer.

Further, the color changing layer 6 mainly comprises a substrate and a color changing material, the substrate is made of water-absorbent materials, the color changing material is made of photosensitive oxidation fading ink, and the needle opening sticker for changing color at the time is packaged by using an opaque packaging material. The color-changing material mainly comprises pigment, ethanol, water, CMC, APG, OP-10, glycerin, photosensitizer, preservative, fading inhibitor and the like. The color-changing material is sprayed on the substrate, so that a graph with a larger area can be sprayed, and the color change can be observed conveniently. Pigments of different colors may be used, depending on preference. The fading time is changed by adding different dosages of the fading resistant agent, and the fading can be finished within 5 minutes, 10 minutes, 15 minutes and the like. In order to prevent the discoloration layer 6 from discoloring in advance, it may be packaged with a light-impermeable packaging material. Either the patch 5 or the sealing patch 7 is made of a material that is opaque to light.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
