Description

[Technical field]

[0001] The present invention relates to a tube fastener, and more particularly to a tube fastener capable of easily and securely fastening a tube attached to a patient by bringing the tube into close contact with the body. [Background technology]

[0002] When performing dialysis, blood transfusion, or infusion, the patient is fitted with a catheter or indwelling needle, and a tube made of synthetic resin such as PVC connected to the catheter. When fitting these devices to the patient, they must be firmly fixed so that the catheter does not come off accidentally due to the patient's movements. For this reason, surgical tape is applied over a wide area around the device, such as the tube, to ensure that the catheter or tube is in close contact with the body.

[0003] When using surgical tape or similar to fix the bandage, a wide area must be fixed with tape each time, which is cumbersome and requires practice. In addition, if the patient has sensitive skin, the area where the tape is applied can become red and itchy, causing a rash over a wide area.

[0004] In order to solve these problems, a tube fixture that does not use tape has been invented (Patent Document 1). The tube fixture of Patent Document 1 includes a band that expands and contracts in the longitudinal direction, two holding members provided on the front and back of the band to hold the tube by sandwiching it from above and below, and a hook-and-loop fastener for fixing the band. To fix the tube with this tube fixture, first, one end of the tube fixture is placed on the patient's wrist. Next, the tube is placed on the first holding member on the band. Then, after wrapping the band around the wrist, the tube is positioned and fixed by hand so that it is sandwiched between the first holding member and the second holding member. Furthermore, while holding the tube by hand, the other end of the band is held and pulled, and the end is fastened with a hook-and-loop fastener to fix the tube.

[0005] [Patent Document 1] JP 2016-101203 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, with the tube fixture of Patent Document 1, one hand must hold the tube between the first holding member and the second holding member, while the other hand must wrap the band around the wrist or the like, and the hook-and-loop fastener must be fastened while pulling the end of the band. Therefore, even with this fixture, it takes some getting used to to fix the tube in the desired position. Also, in order to use this tube fixture to firmly fix the tube so that it does not slip out of place, the hook-and-loop fastener must be fastened while the entire band is pulled strongly. Therefore, a strong feeling of pressure is felt in the area where the tube fixture is attached, and in severe cases, congestion may occur. [Means for solving the problem]

[0007] The invention described in claim 1 is a tube fastener which is wrapped around a patient's body to fasten a tube, comprising a band member which stretches and contracts in the longitudinal direction, and a clamping portion for fixing the tube to one end of the band member, the clamping portion being composed of a pair of clamping pieces which can be folded in half, the inner surfaces of the pair of clamping pieces having clamping members which clamp the tube together and engaging means for fixing the clamping pieces in a folded state, and the tube fastener is characterized in that the end of the band piece which does not have the clamping portion and a specified surface on the side not facing the fixing point of the band member and / or the clamping pieces are provided with engaging means for fixing the tube fastener in a wrapped state around the fixing point of the tube. The invention described in claim 2 is the tube fixture described in claim 1, in which the engaging means is a hook-and-loop fastener. The invention described in claim 3 is a tube fixing device described in claim 1, in which a plurality of anti-slip members are formed at a distance from each other on the surfaces of the band member and the clamping piece that come into contact with the patient. Effect of the Invention

[0008] According to the present invention, it is possible to provide a tube fixing device that can easily and firmly fix a tube attached to a patient by closely contacting the body.

[0009] The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments of the present invention, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The tube fixture 10 according to the present invention includes a band member 12. The band member 12 is for wrapping the tube fixture 10 around a limb such as the arm of a patient to fix it. The band member 12 is stretchable in the longitudinal direction. The tube fixture 10 is fixed to the limb of a patient by utilizing the elastic force generated by the stretchability of the band member 12. Any thin sheet-like or tape-like material having stretchability in the longitudinal direction can be used as the material of the band member 12. However, in order to prevent the patient from developing a rash, it is preferable to use a material that does not contain any substance that causes inflammation and has breathability. In this embodiment, a flat knit fabric that is highly stretchable in the longitudinal direction and has excellent breathability is used for the band member 12.

[0012] A clamping portion 14 is formed at one end of the band member 12. The clamping portion 14 is used to hold a tube attached to a patient. The clamping portion 14 is composed of a pair of clamping pieces 16, 18, and is formed so as to be foldable in two at a boundary 14a between the clamping pieces 16 and 18. In this embodiment, as shown in FIG. 3, one end of the band member 12 is folded back, and a portion a short distance from the folded back point is sewn together in a straight line in the short direction to form the boundary 14a, thereby providing the clamping pieces 16 and 18. Note that the clamping portion 14 does not necessarily have to be formed from the band member 12, and may be configured so that a clamping portion formed from a separate member is attached to the band member 12.

[0013] As shown in FIG. 4, a clamping member 20 and a clamping member 22 are formed on the surface where the clamping piece 16 and the clamping piece 18 face each other, that is, near the boundary 14c on the inner surface of the clamping piece 16 and the clamping piece 18. The clamping member 20 and the clamping member 22 are members that clamp the tube in a pair to fix the tube. The clamping member 20 and the clamping member 22 are provided in two identical pieces at a short distance in the short direction of the band member 12. The clamping member 20 and the clamping member 22 clamp the tube at multiple points rather than at one point. As a result, the tube fixing device 10 firmly clamps the tube at multiple points. A V-shaped groove 20a and a V-shaped groove 22a are provided in the center of the clamping member 20 and the clamping member 22, respectively. The groove 20a and the groove 22a are provided to more firmly clamp the tube without crushing it. The grooves 20a and 22a are formed in a V-shape, so that, as shown in FIG. 6, both thin and thick tubes can be securely clamped with the tube placed in the center of the groove.

[0014] In addition to clamping the tube with grooves 20a and 22a, clamping members 20 and 22 also receive and latch parts that have a larger diameter than the tube, such as the tube connector and locking mechanism, at their upper or lower ends. This makes it easier and more reliable to position and clamp the tube.

[0015] In this embodiment, the groove shapes of groove 20a and groove 22a are not particularly limited as long as they are capable of clamping a tube, and shapes such as a V-shape and semicircular shape are applicable. However, as shown in Figure 6, it is preferable to form them in a V-shape, as this allows both thin and thick tubes to be securely clamped when the tube is placed in the center of the groove. In this embodiment, the clamping members 20 and 22 are made of silicone rubber. This allows the clamping members 20 and 22 to clamp the tube without crushing the tube more than necessary. Furthermore, by forming the clamping members 20 and 22 from silicone rubber, the clamping members 20 and 22 are given anti-slip properties, so the clamped tube does not slip and move. In this embodiment, the clamping members 20 and 22 are made of silicone rubber, but the clamping members 20 and 22 may be made of other materials that have appropriate flexibility and anti-slip properties against the tube. In this embodiment, the tube is clamped using two pairs of clamping members 20 and 22, but the tube may be clamped using one pair of clamping members that have a length sufficient to clamp the tube in the length direction. Conversely, the tube may be clamped using three or more clamping members. In this embodiment, a plurality of clamping members are provided in the length direction of the tube, but the clamping members may be arranged side by side.

[0016] Engagement means 24a and engagement means 24b are formed on the inner surfaces of the open ends of the clamping pieces 16 and 18, respectively. The engagement means 24a and engagement means 24b are for closing the clamping pieces 16 and 18 together to fix the clamping portion 14 in a folded state. By fixing the clamping portion 14 in a folded state with the engagement means 24a and 24b, the tube is fixed in a clamped state by the clamping members 20 and 22. In this embodiment, a pair of hook-and-loop fasteners are provided near the clamping members 20 and 22 as the engagement means 24a and 24b.

[0017] An engagement means 26a is provided on the lower surface around the end 12a of the band portion 12 on the side not provided with the clamping portion, i.e., on the surface facing the fixing point of the tube. An engagement means 26b is also provided on a predetermined surface of the upper surface of the band member 12 and / or the clamping piece 16, i.e., on the surface not facing the fixing point of the tube (such as a human limb) of the tube. The engagement means 26a and the engagement means 26b are configured to be engageable with each other, so that, as shown in FIG. 7, the tube fixture can be fixed in a state of being wrapped around the fixing point of the tube. In this embodiment, only one engagement means 26b is provided on the upper surface of the clamping piece 16, but this is not limited thereto, and multiple engagement means 26b may be provided at intervals on the upper surfaces of the band member 12 and the clamping piece 16. With this configuration, the position at which the end 12a of the band portion 12 is fixed can be adjusted without losing the elasticity of the band member, and fixing points of various thicknesses can be accommodated. Furthermore, the force with which the tube fixture 10 fixes the tube to the fixing point can also be adjusted.

[0018] As shown in FIG. 8, a plurality of anti-slip members 28 are formed at a distance from each other on the lower surfaces of the band member 12 and the clamping piece 16, i.e., on the surface facing the fixing point of the tube. The anti-slip members 28 are formed at a height that prevents the lower surfaces of the band member 12 and the clamping piece 16 from moving away from the fixing point. This allows the tube fixture 10 to be fixed to the fixing point of the tube with high frictional force without impairing the elasticity of the band member 12, so that the tube can be fixed firmly. In this embodiment, the anti-slip members 28 are provided so as to draw a polka dot pattern using silicone rubber, but the anti-slip members 28 may be formed at a distance from each other using other materials having anti-slip properties and flexibility to form a pattern other than polka dots.
