【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing one embodiment of the waterproof cover (A) of the present invention. The waterproof cover (A) of the present invention comprises a cylindrical rubber cover body (1) with both ends opened, a ring-shaped tightening part (3) formed in the opening with a certain width, and a rubber cover body (1). ) And a moisture absorbing member (2) arranged on the inner periphery of the same.

The rubber cover main body (1) is, for example, a thin tube having a thickness of about 10 to 200 μm, which is highly expandable and elastic at both ends, and has an annular tightening portion (3) formed at the opening. There is. In the illustrated embodiment, the annular tightening portion (3) is wide and has a smaller diameter than the main body portion (1a), and the thick tightening ring (4) is integrally formed at the open end thereof. . Of course, the shape and width of the annular tightening portion (3) are not particularly limited, and the annular tightening portion (3) can be made narrower or the tightening ring (4b) on the base side as shown in FIG. 3 (b). ) May be used as the annular tightening portion (3), and the structure may be such that both sides of the portion to be protected are tightened for waterproofing. Further, the tightening ring (4) is not limited to being formed at only one place at the open end as shown in FIG. 2, but may be formed at the base of the annular tightening portion (3) as shown in FIG. , This gives a double waterproof effect. These are shown by (4a) and (4b) in FIG.

As the material of the moisture absorbent member (2), for example, natural materials such as cotton and woven or non-woven fabric or sponge of polyester, acrylic, rayon, acetate and other synthetic resin materials are used. Among these, materials having excellent hygroscopicity are preferable. If necessary, a super absorbent resin may be impregnated or adhered to the surface of the material. In this case, the water absorption is greatly improved, and the thickness of the moisture absorbent member (2) can be reduced.

Further, since the moisture absorbent member (2) is required to be flexible and expands and contracts according to the rubber cover body (1), a thin nonwoven fabric is generally used, and the moisture absorbent member ( An annular fold (2a) or a longitudinal fold (2b) or both an annular fold (2a) and a longitudinal fold (2b) may be formed in 2). The circular folds (2a) facilitate the radial expansion and contraction of the moisture absorbent member (2), and the longitudinal folds (2b) facilitate the longitudinal expansion and contraction and bending of the moisture absorbent member (2). And the movements of the legs are no longer restricted. Further, the moisture absorbent member (2) is generally integrally bonded to the inner peripheral surface of the rubber cover body (1), but it may be simply arranged. Further, although the drawing shows the state in which the moisture absorbing member (2) is arranged on the entire inner peripheral surface of the rubber cover main body (1), it is not limited to this, and of course, a part of the inner peripheral surface of the rubber cover main body (1) is shown. It may be arranged at. Further, the moisture absorbent member (2) may be coated with an antibacterial agent so that it has antibacterial properties, or an antibacterial material such as silver or copper may be woven in or added thereto, and the rubber cover body (1 The surface of () may be coated with a water repellent or kneaded into the inside.

Next, the operation of the waterproof cover (A) according to the present invention will be described. As shown in Figs. 4 and 5, a patient who has been infused continuously by injecting the injection needle (5) into a vein such as a hand, foot or groin (not shown) takes a bath while wearing the injection needle (5). If you want to do this, remove the tube (6) from the connector (8) provided in the middle of the tube (6) that connects the drip device (not shown) and the injection needle (5), and put it on your arm or leg. Wrap the tube (6) on the side of the injection needle (5) around it and use the tape (7) to prevent it from coming off. Next, pass the hand, foot, groin or other necessary part through the waterproof cover (A) of the present invention, and pull up the waterproof cover (A) near the place to be protected so that the annular tightening part (3) is protected. Both sides of the place are tightened so that the body portion (1a) and the moisture absorbing member (2) arranged on the inner periphery of the body portion (1a) surround the place to be protected. In the example shown in this embodiment, since the annular tightening portion (3) has a certain width, it is possible to prevent water from invading from the outside by closely adhering to the arm, the foot, the groin, or any other area adjacent to the protected area. To prevent. Further, when the annular tightening portion (3) is provided with the tightening ring (4), the tightening ring (4) locally tightens linearly to further enhance the waterproof effect.

On the other hand, when taking a bath with the waterproof cover (A) attached, the body temperature rises and sweats, but since the inside of the waterproof cover (A) is in a sealed state, the sweat from the skin remains as it is. 1) Remain inside. This sweat is effectively absorbed by the moisture absorbent member (2) that is in close contact with the skin, and the skin inside the rubber cover body (1) is kept dry. When the moisture absorbent member (2) contains or adheres to the super absorbent resin, sweat is absorbed more effectively. In addition, even if water should enter the rubber cover body (1) after passing through the annular tightening part (3), the moisture absorbent member (2) or the highly water-absorbent resin contained in it will It will not be absorbed and will not wet the area to be protected.

Further, since the rubber cover body (1) itself is extremely thin, it is highly stretchable and also excellent in bendability, twisting and various other deformability, and it is made larger in diameter than the area to be protected. If it is installed (generally thicker than the annular tightening part (3)), the main body part (1a) is the place where the injection needle (5) is attached or the injured part. There is no need to put pressure on areas that should be protected such as. Further, when the moisture absorbent member (2) is also made of a thin non-woven fabric, it easily expands and contracts or bends in accordance with the rubber cover body (1), so that the place to be protected is not pressed. Further, if the moisture absorbing member (2) is formed with an annular fold (2a) or a longitudinal fold (2b) or both an annular fold (2a) and a longitudinal fold (2b), the fold (2a) Stretchability and bending become smoother according to the formation direction in (2b), and there is no hindrance to the movement of the arms, legs, or the like.

When the moisture absorbent member (2) is integrally bonded to the inner peripheral surface of the rubber cover body (1), the moisture absorbent member (2) is attached together with the rubber cover body (1). However, in the case of a separate body, the hygroscopic member (2) is wound around the place to be protected first, and the rubber cover body (1) is arranged on the wound member. In addition, if the moisture absorbent member (2) has antibacterial properties, it is possible to suppress the growth of bacteria even if the moisture absorbent member (2) contains water and the bacteria are easily propagated. It can improve durability and reliability. If the surface of the rubber cover body (1) is coated with a water repellent or kneaded inside, the water repellency will improve, and even if the waterproof cover (A) is immersed in the bath, water will repel water inside. More difficult to enter.
