Description

Technical Field

[0001] The invention relates to the technical field of medical consumables, and in particular to a layered polyurethane sterile scented fingertip and a preparation process thereof. Background Art

[0002] Finger sleeves are medical consumables that can tightly wrap the fingers and assist medical staff in performing medical procedures. This type of finger sleeve not only provides flexible usage, but also provides sterile protection, which is conducive to contact inspection of sensitive parts. However, existing related products often require additional lubricating fluid for use, which makes the overall use more cumbersome and it is not easy to control the amount of lubricating fluid, resulting in a poor overall use experience and unable to meet actual use needs. Summary of the invention

[0003] The purpose of the present invention is to provide a layered polyurethane sterile scented finger cot and a preparation process thereof, which solves the technical problems of the finger cots being inconvenient to use and having poor use experience in the prior art, and achieves the technical effect of simplifying the use method of the finger cots and improving the use experience.

[0004] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0005] A layered polyurethane sterile scented finger cot comprises a sleeve and an adhesive ring, wherein the upper end of the sleeve is provided with a closed end, the side of the sleeve away from the closed end is provided with a tightening end, the lower end of the tightening end is provided with an opening, the side of the closed end away from the tightening end is provided with a tightening seal, the adhesive ring is located on the side of the tightening end away from the closed end, the adhesive ring and the tightening end are an integrated structure and are used for wrapping around the tightening end.

[0006] As an improvement, the sleeve also includes a polyurethane layer, a water-soluble pigment layer and a latex layer, the polyurethane layer is located on the outside, the water-soluble pigment layer is in the middle layer, the latex layer is the inner layer, and the polyurethane layer at the closed end needs to be immersed in essential oil lubricating liquid for processing.

[0007] As an improvement, the essential oil lubricant comprises the following percentage raw materials: 0.1% to 30% crambe seed oil, 0.1% to 30% white meadowfoam seed oil, 0.1% to 30% jojoba oil, 0.1% to 30% high oleic sunflower oil, 0.01% to 1% Australian tea tree essential oil, 0.01% to 1% pine red plum essential oil, and 0.01% to 1% rose geranium essential oil.

[0008] A preparation process of a layered polyurethane sterile scented fingertip comprises the following steps: step 1, conditioning latex, polyurethane and an emulsion of a pigment layer;

[0009] Step 2: Dip the latex into the mold and form a curling edge, then wait for the latex to solidify;

[0010] Step 3: After the latex is cured, dip the mold to which the latex is attached into the liquid of the pigment layer and wait for the pigment layer to dry;

[0011] Step 4: After the pigment layer is dried, dip the mold into the polyurethane solution and wait for it to solidify;

[0012] Step 5: After the polyurethane solution is cured, the finger sleeve is demoulded using a high-pressure water gun;

[0013] Step 6: After demoulding, the finger sleeve is dried and then sterilized by ethylene oxide;

[0014] Step 7, filtering the lubricating liquid through a 0.22 μm filter membrane and then performing vacuum filtration for sterilization;

[0015] Step 8: Under a laminar flow of 100 levels, add lubricating liquid with the closed end of the finger sleeve facing upwards, and then use a filter membrane plastic sealing machine to seal the finger sleeve.

[0016] As an improvement, the main body of the lubricating liquid in step 6 is an aqueous polyurethane emulsion, which can be better mixed and retained with the polyurethane layer, and the water-soluble pigment layer can block further penetration of the aqueous polyurethane solution, thereby reducing the user's allergic reaction.

[0017] The beneficial effects of the present invention are as follows: the sleeve and the rubber ring are provided to facilitate wearing and optimize the wearing feeling; the lubricating liquid can be fully mixed with the outer polyurethane layer by infiltration with the lubricating liquid, so that the outer surface of the finger sleeve is smoother, thereby facilitating use; the use feeling is further optimized by adding fragrances and aseptic processing technology, while ensuring the safety of the product.

[0023] like Figure 1 As shown, a layered polyurethane sterile scented finger cot comprises a sleeve 2 and a rubber ring 4, wherein the upper end of the sleeve 2 is provided with a closed end 1, the side of the sleeve 2 away from the closed end 1 is provided with a tightening end 3, the lower end of the tightening end 3 is provided with an opening, the side of the closed end 1 away from the tightening end 3 is provided with a tightening seal, the rubber ring 4 is located on the side of the tightening end 3 away from the closed end 1, the rubber ring 4 and the tightening end 3 are an integrated structure, and are used to wrap around the tightening end 3. Particles can be added to the outside of the sleeve 2 to further enhance the friction, thereby facilitating use.

[0024] The sleeve 2 also includes a polyurethane layer, a water-soluble pigment layer and a latex layer, wherein the polyurethane layer is located on the outside, the water-soluble pigment layer is located in the middle layer, and the latex layer is the inner layer. The polyurethane layer of the closed end 1 needs to be soaked in an essential oil lubricant. The essential oil lubricant includes the following percentage raw materials: 0.1% to 30% crambe seed oil, 0.1% to 30% white meadowfoam seed oil, 0.1% to 30% jojoba oil, 0.1% to 30% high oleic sunflower oil, 0.01% to 1% Australian tea tree essential oil, 0.01% to 1% pine red plum essential oil, and 0.01% to 1% rose geranium essential oil. The lubricant can be fully compatible with the polyurethane layer to ensure that the fragrance is retained for a long time.

[0025] A preparation process of a layered polyurethane sterile scented finger cot comprises the following steps: step 1, conditioning latex, polyurethane and an emulsion of a pigment layer; step 2, dipping the latex through a mold to form a curling edge, and then waiting for the latex to solidify; step 3, after the latex solidifies, dipping the mold to which the latex is attached into the liquid of the pigment layer, and waiting for the pigment layer to dry; step 4, after waiting for the pigment layer to dry, dipping the mold into a polyurethane solution and waiting for solidification and shaping; step 5, demoulding the finger cot using a high-pressure water gun after the polyurethane solution solidifies; step 6, after demoulding, drying the finger cot, and then sterilizing it with ethylene oxide; step 7, filtering the lubricating liquid through a 0.22-μm filter membrane and then performing vacuum filtration for sterilization; step 8, dripping the lubricating liquid with the closed end of the finger cot facing upwards under a hundred-level laminar flow, and then packaging the finger cot using a filter membrane plastic sealing machine.

[0026] In step 6, the main body of the lubricating liquid is an aqueous polyurethane emulsion, which can be better mixed and retained with the polyurethane layer, and the water-soluble pigment layer can block further penetration of the aqueous polyurethane solution, thereby reducing the user's allergic reaction.

[0027] After testing, the average elongation at break of the finger cot before infiltration was 544.0%, and the average elongation at break after infiltration was 525.7%.

[0028] When in use, after completely washing the hands and arms, tear open the aluminum film package and put the entire finger sleeve on the finger with the rubber ring 4. When the finger is completely released from the closed end 1, slowly lower the wrapped tight end 3 so that the finger sleeve completely wraps the finger.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
