Description

Rubber tourniquet for increasing elongation

The present invention relates to a rubber tourniquet, and more particularly to a rubber tourniquet for increasing elongation.

In the prior art, a rubber stop is used as one of the hemostasis tools for medical use. However, when the rubber stopper is used, the compression of the human body is too large and it is easy to be uncomfortable, and the blood vessel made of the conventional rubber material has poor elongation and elasticity. To overcome the aforementioned drawbacks, a tourniquet made of natural Latex as a material has been developed. Unlike the above-mentioned stop blood vessels, the tourniquet made of natural latex is a band-shaped material, so that it is less likely to be excessively pressed against the human body during use, and the hemostatic effect can be exerted while comfort can be achieved.

However, the aforementioned tourniquet made of natural latex as a material contains other impurities in addition to the polymer as a main component in the natural latex. For example, natural latex typically contains latex proteins, which increase the chances of an allergic reaction in the user's skin.

In detail, latex products are mainly made from rubber trees in Southeast Asia. After the collection, chemicals are added, including ammonia hydroxide, formaldehyde or zinc oxide, to prevent latex from solidifying, deteriorating and inhibiting bacterial growth. However, latex allergens in latex proteins contained in latex (eg, Hev b5, Hev b6, and Hev b7) may cause irritating contact dermatitis, immediate latex allergy, and delayed allergic contact dermatitis.

The technical problem to be solved by the present invention is to provide a rubber tourniquet for improving the elongation of the prior art, which does not contain a protein which causes an allergic reaction in the human body.

In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a rubber tourniquet for improving elongation, which is made of a rubber composition in which two opposites of the rubber tourniquet The surface has an embossing formed by a fabric; wherein the rubber composition comprises: 100 parts by weight of isoprene rubber, 50 to 100 parts by weight of an inorganic filler, 2 to 5 parts by weight of a vulcanizing agent, 5 to 10 parts by weight of the organic filler, and 10 to 20 parts by weight of the plasticizer. The rubber composition does not contain protein.

Preferably, the rubber tourniquet has a thickness of between 0.2 and 1 mm.

Preferably, the fabric is nylon or polyester.

Preferably, the rubber tourniquet has an elongation of at least 1000% and a tensile strength of at least 10 MPa.

Preferably, the inorganic filler is selected from the group consisting of calcium carbonate, calcined earth, white smoke, and white carbon black.

Preferably, the plasticizer is a phthalate-free paraffin-based processing oil.

One of the beneficial effects of the present invention is that the rubber tourniquet provided by the present invention for increasing the elongation can pass "the opposite surfaces of the rubber tourniquet have an embossing formed by a fabric" and " The rubber composition comprises 100 parts by weight of isoprene rubber, 50 to 100 parts by weight of an inorganic filler, 2 to 5 parts by weight of a vulcanizing agent, 5 to 10 parts by weight of an organic filler, and 10 to 20 parts by weight of a plastic. The technical characteristics of the agent to enhance the elongation of the rubber composition. In addition, this creation can also achieve the effect of avoiding allergic reactions when the human body is used, through the technical characteristics of "the rubber composition does not contain protein".

The following embodiments will further explain the related technical content of the present invention, but the disclosure is not intended to limit the scope of protection of the present invention.

First, please refer to Figure 1. 1 is a schematic view of a rubber tourniquet for increasing elongation provided by the present embodiment. The rubber tourniquet 1 is a strip-shaped strip made of a rubber composition. Specifically, in order to overcome the disadvantages of the prior art, the rubber tourniquet 1 for improving the elongation provided by the present embodiment is a rubber composition having a specific composition and a ratio, and a specific treatment method is adopted in the manufacturing process. . The method of manufacturing the rubber tourniquet 1 will be described in detail later. Next, the composition and ratio of the rubber composition for producing the rubber tourniquet 1 are first targeted.

The rubber composition used in the present working example contains 100 parts by weight of isoprene rubber, 50 to 100 parts by weight of an inorganic filler, 2 to 5 parts by weight of a vulcanizing agent, and 5 to 10 parts by weight of an organic filler. And 10 to 20 parts by weight of a plasticizer. Preferably, the rubber composition comprises 100 parts by weight of isoprene rubber, 65 to 85 parts by weight of an inorganic filler, 3 to 4 parts by weight of a vulcanizing agent, and 6 to 9 parts by weight of an organic filler. Filling, and 12 to 18 parts by weight of a plasticizer. The optimum elongation can be obtained by using the above composition and the proportion of the rubber composition.

In the above rubber composition, the isoprene rubber is composed of polyisoprene, and the monomer constituting the polyisoprene is isoprene (also known as methyl group). 1,3-butadiene, which is a conjugated diene, and polymerizes under specific conditions to produce polyisoprene.

In the rubber composition used in the present embodiment, artificially synthesized polyisoprene (hereinafter referred to as "synthetic natural rubber") is used in place of the natural latex used in the conventional latex product. In this way, the allergic reaction caused by the latex protein in the natural latex can be effectively avoided, and the safety of the product is increased. In addition, since synthetic natural rubber does not contain other impurities (including proteins, carbohydrates, and lipids), it is not necessary to go through conventional separation procedures (such as ammoniation and centrifugation) during the manufacturing process. Therefore, the rubber composition used in the inventive example does not contain protein.

The inorganic filler is selected from the group consisting of calcium carbonate, calcined earth, white smoke, and white carbon black. The organic filler may be stearic acid. The addition of organic and inorganic fillers increases the hardness, tensile strength, abrasion resistance and tear resistance of rubber products. The plasticizer is a paraffin-based processing oil containing no phthalate. The addition of a plasticizer to the composition allows the resulting product to have better elasticity and softness. The vulcanizing agent may be selected from the group consisting of sulfur, an organic accelerator, and zinc oxide. The vulcanizing agent is used to cause the rubber composition to undergo a curing reaction at a high temperature.

Next, in step S102, the rubber composition which has been kneaded and mixed as described above is fed into a calendering laminator by a conveyor belt to form a belt-shaped material having a specific thickness. The thickness of the strip material can be adjusted according to the parameters set by the calendering laminator. As mentioned before, the thickness of the strip material can range from 0.2 mm to 1.0 mm. between.

In step S104, two fabrics are attached to the opposite surfaces of the strip material. Specifically, in this step, a fabric such as nylon or polyester fiber is coated on the opposite surfaces of the strip material for pressing the surface of the strip material to form a texture through a subsequent step. .

Next, in step S106, the strip material to which the two fabrics are attached is vulcanized. In step S106, the strip material coated with the two fabrics is fed to a drum vulcanizer and vulcanized in a temperature range of 130 to 160 °C. Finally, in step S108, the two fabrics and the strip material are separated from each other. After separating the fabric from the strip material, the surface of the vulcanized strip material has embossing, i.e., the rubber tourniquet 1 for elongating elongation provided by the presently-created embodiment.
