Description

The present disclosure relates to a waterproof protector and a method of mounting the waterproof protector.

In some cases, a tube (catheter) is attached to the patient's arm or the like in order to perform infusion or artificial dialysis. When a patient with a tube or the like attached takes a bath, it is necessary to protect the attached portion from getting wet. As a method of preventing the mounting portion from getting wet, there is a method of wrapping a wrap or the like and fixing both ends with an adhesive tape or the like. This method requires skill in order to provide sufficient waterproofing, and has a problem that the procedure takes time. It is also considered to use a tubular or bag-shaped waterproof protector having a belt or the like at the end (see, for example, Patent Document 1), but it is ineffective if the belt is not sufficiently tightened, and if it is tightened too much There is a problem of inhibiting blood circulation.

A waterproof protector made of an elastic material and having a thickness such that the end of the arm is in close contact with the arm when fitted to the arm has also been studied (see, for example, Patent Document 2). By simply inserting the arm, the end portion is in close contact with the arm, a sufficient waterproof effect can be easily obtained, and excessive tightening can be prevented.

However, the conventional waterproof protector made of an elastic material has a problem that it is difficult to attach. The conventional waterproof protector is attached while pushing the end portion with the arm, and at this time, the tube may be caught or the attachment portion of the tube may be greatly pressed. In order to avoid the influence on the mounting part, it is conceivable to insert the arm in a state where the end is pulled by hand and expanded, but it is difficult to wear by one person.

Such problems occur not only in the arms but also in other parts of the body such as the legs and torso. Further, the same problem occurs not only in the mounting portion of the tube but also in all the protective sites such as the fixing portion by the cast and the wound portion that require waterproofing.

An object of the present disclosure is to make it possible to realize a waterproof protector that is easy to install and does not easily affect the protected portion.

One aspect of the waterproof protector of the present disclosure is an outer cylinder in which the cover body can be mounted inside by folding back a tubular cover body formed of an elastic material and covering the end portion of the cover body on the outer wall side. By inserting a part of the body including the protective part into the cover body attached to the outer cylinder and extending the folded end of the cover body to bring it into close contact with the part of the body. Covers the protected area to make it waterproof.

According to one aspect of the waterproof protector, the waterproof protector can be easily attached by inserting a part of the body including a protective portion such as an arm into the cover body attached to the inside of the outer cylinder.

In one aspect of the waterproof protector, the cover body may have a central portion and small diameter portions provided at both ends of the central portion and having a diameter smaller than that of the central portion. In this way, it is possible to prevent excessive compression by the waterproof protector while ensuring waterproofness at both ends.

In one aspect of the waterproof protector, the outer cylinder may have an exhaust port for exhausting air between the inner wall and the outer wall of the attached cover body. In this way, the cover body attached to the inside of the outer cylinder can be further expanded, and the insertion of the arm or the like becomes easier.

One aspect of the method of mounting the waterproof protector of the present disclosure is a step of mounting a tubular cover body formed of an elastic material inside the outer cylinder by folding back the end portion and covering the outer wall side. Insert a part of the body including the protective part into the cover body attached to the outer cylinder, extend the folded end of the cover body and bring it into close contact with the part of the body so that the cover body covers the protective part. It has stages.

According to one aspect of the method of attaching the waterproof protector, a part of the body including the protective part is inserted into the cover body attached to the outer cylinder to attach the waterproof protector, so that the inserted tube or the like may be caught. , It is possible to prevent excessive pressure on the protected area.

In one aspect of how to attach the waterproof protector, between the inner wall of the outer cylinder and the outer wall of the cover body after the cover body is attached to the outer cylinder and before a part of the body is inserted into the cover body. It may further include a step of exhausting the air. By doing so, the cover body can be further expanded, and the insertion of the arm or the like becomes easier.

It is sectional drawing which shows the modification of the cover body.

As shown in FIG. 1, the waterproof protector 100 of the present disclosure includes a cover main body 101 and an outer cylinder 102 to which the cover main body can be mounted inside. The cover body 101 has a tubular shape made of an elastic material such as rubber, has a thickness at which at least the end 111 is in close contact with the arm 161 to be mounted, and is a mounting portion of the tube (catheter) 163. It has a length that can sufficiently cover the protected portion 162. The outer cylinder 102 has a thickness and a length so that the cover main body 101 can be mounted inside by folding back the end portion 111 of the cover main body 101 and covering it on the outer wall side. In addition, it has the strength to maintain its shape when the cover body 101 is mounted inside.

When the cover body 101 is not extended, at least the inner diameter of the end 111 is smaller than the outer diameter of the arm 161 to be attached. The outer cylinder 102 has an inner diameter sufficiently larger than the outer diameter of the arm 161. Therefore, as shown in FIG. 1, when the end 111 of the cover main body 101 is folded back and put on the outer wall side of the outer cylinder 102 and the cover main body 101 is attached to the inside of the outer cylinder 102, the arm 161 is placed inside the cover main body 101. It can be easily inserted into. Therefore, it is possible to prevent the tube 163 attached to the arm 161 from being caught by the cover main body 101, or the protective portion 162 of the arm 161 from being excessively pressed by the cover main body 101.

Depending on the size of the cover main body 101 and the outer cylinder 102, the space 151 between the inner wall of the outer cylinder 102 and the outer wall of the cover main body 101 may become large, and it may be difficult to insert the arm 161 inside. In such a case, by exhausting the air between the inner wall of the outer cylinder 102 and the outer wall of the cover main body 101, the inner diameter of the cover main body 101 mounted inside the outer cylinder 102 is changed to the outer cylinder 102. It can be made approximately equal to the inner diameter, making it easier to insert the arm 161.

When the air between the inner wall of the outer cylinder 102 and the outer wall of the cover main body 101 is exhausted, for example, as shown in FIG. 2, the outer cylinder 102 may be provided with an exhaust port 121 and exhausted by the pump 171. FIG. 2 shows a tubular exhaust port 121 protruding outward, but the present invention is not limited to this, and any configuration may be used as long as air can be sucked out. The pump 171 used for exhaust may be any type, and an electric pump or a manual pump can be used. After exhausting, a valve 172 can be provided between the exhaust port 121 and the exhaust pump in order to maintain the state. Further, a valve may be incorporated in the exhaust port 121, or a check valve for preventing the inflow of air may be provided in the exhaust port 121.

FIG. 3 shows a cover main body 101 having a central portion 112 and a small diameter portion 113 provided at both ends of the central portion 112 and having a diameter smaller than that of the central portion 112. The inner diameter of the small diameter portion 113 when not extended is smaller than the outer diameter of the arm, and when the arm is inserted, it is extended and sufficiently adheres to the arm. Although FIG. 3 shows an example in which the diameters of the small diameter portions 113 at both ends are different, they can be the same. The thickness of the arm is generally different between the wrist side and the shoulder side, and by making the diameters of the small diameter portions 113 at both ends different, the adhesion to the arm can be further improved.

As shown in FIG. 4, an annular rib 115 having a wall thickness thicker than that of the other portion can be provided on the inner surface of the small diameter portion 113. By providing the annular rib 115, the adhesion to the arm can be further improved. Although FIG. 4 shows an example in which three annular ribs 115 are provided, the number of annular ribs 115 may be one, two, or four or more. Further, the annular rib 115 may or may not be provided as needed.

In FIG. 4, a wall thickness portion 116 having a wall thickness higher than that of the annular rib 115 is provided at an end portion of the small diameter portion 113. By providing the thick portion 116, the adhesion to the arm can be further improved. Further, since the strength is also improved, it is possible to prevent the end portion 111 of the cover main body 101 from being torn when it is attached to the outer cylinder 102. The thick portion 116 may or may not be provided as needed. The axial length of the thick portion 116 is preferably 1.0 mm to 6.0 mm. Sufficient adhesion can be obtained by setting the thickness to 1.0 mm or more, and the small diameter portion 113 can be easily opened by setting the thickness to 6.0 mm or less.

Since the inner diameter of the central portion 112 is larger than that of the small diameter portion 113, the central portion 112 does not press the arm as compared with the small diameter portion 113. Therefore, it is possible to relieve the pressure on the arm while ensuring the waterproofness of the cover body 101 as a whole. The inner diameter of the central portion 112 may be large enough to relieve the pressure on the arm, and may be slightly smaller than the outer diameter of the arm when it is not extended. It is also possible to make the inner diameter when not stretched sufficiently larger than the outer diameter of the arm so that the protective portion does not come into contact with the inner wall of the cover body 101.

As shown in FIG. 5, the moisture absorbing member 118 can be provided inside the central portion 112. By providing the moisture absorbing member 118, it is possible to reduce the discomfort caused by dew condensation inside the cover body 101. The moisture absorbing member 118 can be fixed to the inner wall of the cover body 101 with an adhesive or the like. The hygroscopic member 118 can be a woven fabric, a non-woven fabric, a sponge or the like made of a hygroscopic material. Antibacterial properties may be imparted to the moisture absorbing member 118.

Although an example in which the central portion 112 and the small diameter portion 113 are provided on the cover main body 101 is shown, the cover main body 101 can have a cylindrical shape having a constant diameter. Further, it may be a truncated cone-shaped cylinder in which one diameter is larger than the other diameter.

By forming the cover body 101 into a tubular shape with both ends open, it is possible to penetrate the arm and waterproof only the periphery of the protected portion. However, the cover body 101 may have a tubular shape with one end closed. In this case, the end portion on the opened side may be folded back so as to cover the outer wall side of the outer cylinder 102. For example, when it is desired to waterproof the vicinity of the wrist or the like, if the cover body 101 with one end closed is used, a larger waterproof effect can be expected and the wearing becomes easy.

The cover body 101 may be formed of a material having appropriate elasticity, and can be formed of, for example, silicone rubber, styrene-based elastomer, polyurethane, or the like. Of these, a material having water repellency is preferable. By using a material having water repellency, it is possible to make it more difficult for water to enter the inside. In order to impart water repellency, a water repellent agent can be applied to the surface of the cover body 101, or the cover body 101 can be formed of a material kneaded with the water repellent agent.

When the cover body 101 is made of silicone rubber, styrene elastomer, polyurethane or the like, the thickness can be, for example, about 0.5 mm to 2.5 mm. The entire cover body 101 may have the same thickness, but the thickness of the end portion in close contact with the arm may be increased and the thickness of the central portion may be decreased. By doing so, it is possible to relieve the feeling of oppression while ensuring the adhesion.

The outer cylinder 102 may have a cylindrical shape having a constant diameter, but one diameter may be larger than the other diameter. By smoothing the inner wall surface of the outer cylinder 102, the arm can be easily inserted. However, ribs or the like for reinforcing the outer cylinder 102 can be provided on at least one of the inner wall surface and the outer wall surface. Further, a ring-shaped groove, a convex portion, or the like can be provided on the outer wall surface near the end portion of the outer cylinder 102. By providing a protrusion, a ring-shaped convex portion, a groove portion, or the like on the outer wall surface near the end portion, it becomes easy to fold back and cover the end portion 111 of the cover main body 101. In addition, it is possible to prevent the end portion 111 that has been folded back and covered from slipping off.

The outer cylinder 102 can be formed of a material that does not deform significantly when the cover body 101 is attached. For example, it can be formed of a hard resin such as polycarbonate, acrylic or hard vinyl chloride, a metal or the like. Further, the paper can be made of a thickness having the required strength. Reinforcements such as ribs can also be provided to meet the required strength.

The size of the cover body 101 and the outer cylinder 102 may be designed according to the mounting target. For example, the cover body has an end diameter of about 10 mm to 70 mm and a length of about 30 mm to 150 mm when not extended. The diameter of the central portion can be about 30 mm to 150 mm, and the length can be about 50 mm to 200 mm. In this case, the inner diameter of the outer cylinder can be 40 mm to 200 mm.

When the waterproof protector 100 of the present disclosure is attached to the arm, first, the cover main body 101 is attached to the outer wall side of the outer cylinder 102 by folding back the end portion 111, and the cover main body 101 is attached to the inside of the outer cylinder 102. .. When the outer cylinder 102 is provided with the exhaust port 121, the air between the inner wall of the outer cylinder 102 and the outer wall of the cover main body 101 can be exhausted, if necessary. As a result, the space for inserting the arm can be further expanded.

Next, the arm is inserted into the cover body 101 attached to the outer cylinder 102. At this time, it is preferable that the protective portion is located at the center of the cover body 101 in the longitudinal direction. After that, the folded end 111 of the cover body 101 is extended, removed from the outer cylinder 102, and brought into close contact with the arm. As a result, the cover body 101 covers the protected portion, and the protected portion is waterproofed. After the cover body 101 has been attached to the arm, the outer cylinder 102 is removed from the arm.

In the case of the cover body that is brought into close contact with the arm by the restoring force of the material, there is a portion having a smaller diameter than the arm in the unextended state. If the arm is forcibly inserted into this part, the protected part may be caught or excessively compressed. In the waterproof protector of the present embodiment, the cover body can be attached to the inside of the outer cylinder, and the arm can be inserted with the cover body extended. Therefore, it is possible to prevent the protected portion from being caught or excessive pressure on the protected portion.

In the present embodiment, an example in which the wearing target is an arm has been described, but not only the arm but also a part of the body such as a finger, a leg, a head, and a torso can be a wearing target. The sizes of the cover body and the outer cylinder may be appropriately adjusted according to the size of a part of the body to be attached.

The protective site can be a site to which the tube is attached by an indwelling needle, a catheter, or the like, but is not limited to this, and can be applied to any site that requires waterproofing. For example, it can be applied to a portion fixed by a cast, a portion having a trauma or the like, and a portion having a lesion or the like.

Although the example in which the cover body is directly attached to the attachment site is shown, the cover body can be attached after covering the protective portion with a wrapping bag or a supporter. In this way, the discomfort caused by dew condensation inside the cover body can be reduced. In addition, the cover body can be prevented from being caught by the protective portion.

The waterproof protector of the present disclosure is useful as a medical waterproof protector or the like, which is easy to wear, does not easily affect the protected part, and waterproofs and protects the protected part such as the catheter insertion part.
