[Technical Field]
[0001] Medical Finger Cots [Background technology]
[0002] Finger cots, also known as finger caps, are a type of protective equipment widely used in medical care and daily life. A finger cot production mold refers to the fixed mold used to manufacture finger cots. After molding the finger cot at the tip of this mold, a release process is performed, enabling rapid production of finger cots. Currently, commonly used disposable medical finger cots are primarily made from materials such as vulcanized rubber, natural rubber, polyurethane, and resins such as polyisoprene.
[0003] In the medical field, finger cots are used by medical professionals for hygiene or palpation, and are similarly produced at high speed using molds with a release process. Most finger cots are disposable, functioning as protective devices covering one or more fingers, isolating contamination, preventing infection, and providing anti-slip properties. Their use in various medical settings, such as medical examinations, medication administration, and surgery, effectively prevents cross-infection. For example, Chinese Utility Model Publication CN222752048U, entitled "Disposable Finger Cot for Arterial Blood Gas Puncture," discloses the following features: a finger cot body with at least one open end; the thickness of the finger pad (palm side) of the finger cot body is thinner than the thickness of the dorsum (back side) and tip (fingertip), with the finger pad thickness being 0.08 mm or less; and a sterilized film on the finger pad and a tension film on the open end of the finger cot body.
[0004] The utility model described in the above-cited document not only improves the accuracy and safety of arterial blood gas puncture through its innovative design, but also significantly enhances the convenience of operation and the comfort of medical professionals, thereby contributing to the improvement of medical service quality. However, existing medical finger cots have several defects in their shape and structure. Specifically, most existing medical finger cots are provided in a dry state, which results in a lack of lubrication and discomfort during intracavity palpation. Furthermore, because the finger cots are directly exposed to air, their hygiene cannot be completely guaranteed. Furthermore, existing finger cots are prone to falling off during palpation, posing a risk of being left inside the body cavity. Summary of the Invention
[0005] The purpose of this utility model is to provide a disposable finger cot for medical use that has good lubrication and antiseptic properties on the outer surface, and whose ends easily fit tightly to the fingertips and are less likely to fall off. [Problem to be solved by the invention]
[0006] To achieve the above objectives, this utility model adopts the following technical solutions: [Means for solving the problem]
[0007] As one of the disposable medical finger cots, in addition to the finger cot body, a closed end is provided at the upper end of the finger cot,
[0008] Parallel end: Provided in the center of the finger sack,
[0009] Rubber ring: This is to be provided at the end of the finger cot, and preferred embodiments include the following items.
[0010] The end of the closed end is a cone-shaped area closing structure, and both ends of the parallel end are integrally molded with the closed end and the rubber ring, respectively.
[0011] The finger cot is placed inside the packaging bag, and the packaging bag is made of aluminum foil.
[0012] An antiseptic lubricant is dripped into the packaging bag, the antiseptic lubricant is used for external lubrication and antiseptic purposes for the finger cot, and the packaging bag is used to seal and package the finger cot and antiseptic lubricant inside.
[0013] The total length of the fingerstall is 50 to 100 mm, the rubber ring is used to secure the bottom of the fingerstall, and the fingerstall has a gradually contracting conical structure around the front 50 mm end.
[0014] The closed end and the parallel end are both provided with anti-slip protrusions on the outside, and the anti-slip protrusions have a granular protrusion, a transverse thread, a longitudinal rib, a rough surface, and a polygonal rib structure.
[0015] The bottom end of the parallel end and the rubber ring have a trumpet-shaped structure, and the fingertip of the finger cot is semi-elliptical, with the ratio of axis length to diameter being in the range of 0.7:1 to 2:1. [Effects of the Invention]
[0016] Compared to existing technology, this utility model provides the following advantages. The materials used for the disposable medical finger cots in this utility model are primarily natural rubber and resins such as polyisoprene, polyurethane, and silicone. The finger cots are sealed in a disposable packaging bag, which has easy-peel grooves (cut grooves) on both sides of the exterior that allow the finger cot to be removed. Furthermore, the lubricating liquid in the packaging bag infiltrates the exterior of the finger cot, helping it slide smoothly and providing sterility and preventing spoilage / deterioration, thereby avoiding problems such as surface drying and the inability to ensure hygiene that can occur when the finger cot comes into direct contact with air.
[0017] This utility model features a gradually contracting cone structure around the front 50mm of the finger cot. This structure allows the finger cot to apply appropriate pressure from the sides to the finger, ensuring a snug fit around the finger and reducing the risk of it falling off. The closed end of the finger cot is semi-elliptical, which allows it to fit more snugly to the fingertip than the semi-circular heads of existing finger cots, providing the advantage of a closer fit to the wearer's finger. Anti-slip protrusions on the closed end and the outer parallel end of the finger cot enhance the anti-slip effect between the finger cot and the cavity. Furthermore, these protrusions, in conjunction with the rubber ring at the end, facilitate a tight fit to the outside of the finger, allowing medical personnel to easily perform indirect manipulations during surgery.

[0019] The technical solutions of the present invention will be clearly and completely described in the following embodiments of the present invention in conjunction with the drawings, but the described embodiments are only some of the embodiments of the present invention and are not intended to cover all the embodiments.
[0020] This example describes a disposable medical finger cot as shown in Figures 1 to 4. The disposable medical finger cot includes a finger cot body 10 and the following elements: Closed end 100: Provided at the upper end of the finger cot 10.
[0021] The closed end 100 has a conical closed structure, and both ends of the parallel end 200 are integrally molded with the closed end 100 and rubber ring 300, respectively. The finger cot 10 is placed inside a packaging bag 400, which is made of aluminum foil. Antiseptic lubricant is dispensed inside the packaging bag 400, lubricating the outer surface of the finger cot 10 while providing antiseptic and anti-deterioration properties. The packaging bag 400 is used to seal and enclose the finger cot 10 and antiseptic lubricant inside. The lubricant used in the finger cot 10 can be primarily composed of hyaluronic acid liquid if it is water-based, or primarily composed of silicone oil if it is oil-based. The lubricant inside the packaging bag 400 thoroughly infiltrates the exterior of the finger cot 10, providing slipperiness to the exterior while also providing sterility and antiseptic and anti-deterioration properties. This makes it possible to avoid problems such as dryness and roughness on the surface of finger cot 10 that can occur when finger cot 10 comes into direct contact with air, as well as the difficulty of maintaining hygienic conditions.
[0022] The materials that can be used for the disposable medical finger cot 10 in this embodiment include natural rubber and resins such as polyisoprene, polyurethane, and silicone. The finger cot 10 is sealed in a packaging bag 400, which has easy-peel grooves (cut grooves) on both sides of the exterior that allow the finger cot 10 to be removed from the inside. The lubricating liquid in the packaging bag 400 infiltrates the exterior of the finger cot 10, helping the exterior of the finger cot 10 to slide smoothly, and also has antibacterial and anti-septic / anti-deterioration properties, making it possible to avoid problems such as surface drying and an inability to ensure hygiene that can occur when the finger cot 10 comes into direct contact with air.
[0023] In Example 2, a disposable medical finger cot will be described based on Example 1. As shown in Figure 2, this disposable medical finger cot includes the following elements: Parallel end 200: Attached to the center of the finger cot 10. Rubber ring 300: Attached to the bottom end of the finger cot 10. The total length of the finger cot 10 is 50 to 100 mm, and the rubber ring 300 is used to firmly secure the bottom of the finger cot 10. A gradually contracting conical structure is provided 50 mm from the tip of the finger cot 10. Another gradually contracting conical structure is provided 50 mm from the tip of the finger cot 10. This structure applies more appropriate pressure to the finger body from the side, ensuring a tight fit around the finger body and reducing the risk of it falling off.
[0024] Additionally, the closed end 100 and the parallel end 200 each have a non-slip protrusion on their exterior. These non-slip protrusions can be convex, horizontally twisted, vertically ribbed, pear-shaped, or polygonal cord-shaped. The bottom end of the parallel end 200 and the rubber ring 300 have a trumpet-shaped structure. The tip of the finger cot 10 is semi-elliptical, with an axis length to diameter ratio of 0.7:1 to 2:1. For example, if the radius is 16 mm, the axis length of the tip is between 11.2 mm and 64 mm. The closed end at the tip of the finger cot 10 can be semi-elliptical, parabolic, or flattened, providing improved adhesion compared to conventional semi-circular heads. The non-slip protrusions on the exterior of the closed end 100 and the parallel end 200 of the finger cot 10 enhance the non-slip effect between the finger cot and the cavity. The protrusions cooperate with the rubber ring 300 at the end to make it easier to fit tightly to the outside of the finger, allowing the wearer to indirectly perform medical procedures easily during surgery.
[0025] In this embodiment, the closed front end 100 of the finger cot 10 has a semi-elliptical structure, which allows for a more comfortable fit to the fingertip. This provides an advantage over the semi-circular heads at the ends of existing finger cots 10, allowing for a closer fit to the wearer's finger. Anti-slip protrusions on the outside of the closed end 100 and the parallel end 200 of the finger cot 10 enhance the anti-slip effect between the finger cot and the cavity. Furthermore, these protrusions, in conjunction with the rubber ring 300 at the end, allow for a more comfortable fit to the outside of the finger, making it easier for medical personnel to perform indirect manipulations during surgery.
[0026] Operating principle: When using the disposable medical finger cot 10, the packaging bag 400 has easy-peel grooves (cut grooves) on both sides of the exterior, which allow the finger cot 10 to be removed. The lubricating liquid in the packaging bag 400 infiltrates the exterior of the finger cot 10, helping it slide smoothly, while also providing sterility and antiseptic / deterioration protection, thereby preventing problems such as surface drying and the inability to ensure hygiene that can occur when the finger cot 10 comes into direct contact with air.
[0027] Furthermore, the closed end 100 of the finger cot 10 is semi-elliptical, which allows it to fit more snugly to the fingertip than the semicircular heads at the ends of existing finger cots 10, giving it the advantage of being able to fit more snugly to the wearer's finger. The anti-slip protrusions on the outside of the closed end 100 and the parallel end 200 of the finger cot 10 enhance the anti-slip effect between the finger cot and the cavity. Furthermore, these protrusions, in conjunction with the rubber ring 300 at the end, allow for easier fitting to the outside of the finger, making it easier for medical personnel to perform indirect manipulations during surgery.
[0028] While embodiments of the present invention have been described and illustrated, those skilled in the art will recognize that various modifications and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is intended to be limited by the appended claims and their equivalents.
