Description

DEVICE FOR FIXING CATHETER < RTI ID = 0.0 >

The present invention relates to a catheter fixation device, and more particularly, to a catheter fixation device that fixes the catheter so that it is not moved arbitrarily when the catheter is inserted into the body through the skin.

A catheter refers to a hollow tube-shaped surgical instrument that is inserted into a body cavity such as pleural or peritoneal fluid or a tubular organ such as an organ, esophagus, stomach, bowel, bladder, ureter, or blood vessel. Although the catheter was originally used to measure the amount or composition of the contents liquid discharged from the organs, it is also used for the purpose of securing a passage for injecting a detergent, a medicine, or inserting a sensor.

Thus, when the external force is applied to the catheter installed in the body of the subject, the catheter must be detached from its original position and reinserted or infected. In this case, the catheter is inserted into the body through the through- And may cause pain to the subject.

Therefore, various measures have been proposed for securing the catheter so that it is not released and moved even when an external force is applied to the catheter.

As a part of this, a skin suturing method in which a catheter is fixed to a subject's skin with a suture is now in use. However, it takes a lot of time to seal the skin, and when an external force is applied to the catheter due to the cause of movement of the subject, the pulling force is applied to the skin through the suture so that the subject is not only painful, It has the disadvantage that it can not.

To solve these drawbacks, Korean Patent No. 10-1459313 (hereinafter referred to as "Patent Document 1") has been proposed.

The medical suction device fixing device according to Patent Document 1 is characterized in that a tube (catheter) of a medical suction device is fixedly coupled to an edge portion, and a tube storage space for accommodating a portion (hereinafter referred to as a "through hole" Wherein the tubular member support comprises a tubular member support which is attached to the skin. The tube support is provided with a cover member that can be opened and closed so that the inside of the tube storage space can be observed.

Here, though the through hole is covered by the cover member, the cover member is not completely sealed, so there is a risk of infection through the through hole. In order to prevent the above infection, sterilization There is considerable difficulty in doing so.

In addition, there is a high possibility that exudates such as blood or abscess may leak out between the through-hole and the tube. Such exudates accumulate in the tube accommodation space and are likely to be leaked out of the tube support member when the cover member is opened. When exudates are leaked out, the subject is more likely to feel anxiety.

In order to prevent such infections and leakage of exudates, Korean Patent Registration No. 10-1386262 (hereinafter referred to as Patent Document 2) discloses a method for preventing leakage of exudates generated from a through-hole into which a drain tube (catheter) is inserted Discloses a leakage liquid discharging apparatus provided with a transparent bag to collect.

However, since one side of the O-ring supporting the transparent bag is fixed to the skin, it is difficult to ensure the airtightness of the O-ring, so that there is a disadvantage that infection with bacteria or the like introduced from the outside is high.

In addition, since the exudates are accumulated in the transparent bag, if the drain tube is inserted for a long time, the penetration hole and the surrounding skin are blocked by air and continuously contact with the exudates, Is high.

Therefore, there is a need to provide a catheter fixation device that securely fixes a catheter inserted in a through-hole, has a low risk of infection, does not leak exudate, and does not cause side effects due to exudates.

Referring to FIGS. 1 and 2, a catheter fixing apparatus 100 according to an embodiment of the present invention includes an attachment sheet 110, an absorbent member 130, a fixing means 150, and a release paper 170.

The attachment sheet 110 includes an attachment sheet body 111.

The attachment sheet main body 111 may be configured such that one surface thereof is attached to the skin (10 in Fig. 3). That is, the adhesive sheet main body 111 is made of a flexible material, and an adhesive may be applied to one surface of the adhesive sheet main body 111 so that the adhesive sheet main body 111 is firmly attached to the skin 10.

As the adhesive, a pressure sensitive adhesive may be used. In particular, a hypoallergenic pressure sensitive adhesive (PSA) may be used to prevent skin rashes and the like. Since the hypothetical pressure-sensitive adhesive (PSA) is used for a patch or bandage directly attached to the skin, a description thereof will be omitted.

Since the attachment sheet main body 111 may be kept attached to the skin for a long period of time, it may be made of a breathable and moisture-permeable material such as nonwoven fabric or cotton to prevent skin from being damaged.

However, when it is necessary to prevent moisture or the like from penetrating from one surface of the other surface of the attachment sheet main body 111, the other surface of the attachment sheet main body 111 may be covered with a material such as Gore-Tex.

The through hole 117 and the opening 118 are formed in the attachment sheet main body 111. The opening 118 is formed so as to extend from the edge to the middle of the attachment sheet body 111 and the through hole 117 is formed at the end of the opening 118 disposed in the middle portion of the attachment sheet body 111 .

The through hole 117 may be formed to have a size corresponding to the diameter of the catheter (21 in FIG. 3), though not shown, the through hole 117 may not be formed as needed.

A through hole 137 and an opening 138 are formed in the absorbing member main body 131 and the opening 138 is formed so as to extend from an edge of the absorbing member main body 131 to an intermediate portion. The opening portion 138 is formed at a position corresponding to the opening portion 118 of the attachment sheet body 111 and the through hole 137 is also formed to have a size corresponding to the position corresponding to the above- .

However, if the through hole 117 of the attachment sheet body 111 is not formed as described above, the through hole 137 may not be formed in the absorbing member main body 131 as well. This will be described again with reference to Figs. 3 and 4 below.

The absorbent member main body 131 is made of a material having absorbency so as to absorb exudates such as blood or abscesses flowing out from between the through holes 11 and the catheter 21, And is made of a material having flexibility.

The absorbent member main body 131 may include a cellulose sponge, a super absorbent polymer (SAP), a hydrocolloid sheet, a hydrocolloidal polyurethane foam sheet, or the like.

An adhesive may be applied to one surface of the absorbent member main body 131 such that the absorbent member main body 131 is adhered well to the portion of the skin 10 where the through hole 11 is formed.

However, the adhesive may be applied only to one edge portion of the absorbent member main body 131 in order to prevent the absorbent member 131 from being deteriorated in absorbability and to prevent the adhesive from flowing into the body through the through hole 11 . In this case, a hypothetical pressure-sensitive adhesive as described above may be used as the adhesive.

The releasing sheet 170 is attached to one side of the attachment sheet main body 111 and the other side of the absorbent member main body 131 in order to prevent the adhesive applied thereto from being stained or adhering to an object other than the skin 10, And covers one surface of the absorbing member main body 131.

The release papers 170 may be formed as a plurality of (171, 175) to facilitate separation as shown, or may be formed as one, though not shown.

The through holes 172 and the openings 173 and 177 may also be formed in the plurality of release papers 171 and 175 for convenience of manufacturing.

That is, when the through holes 117, 137, 172 and the open portions 118, 138, 173 are integrally formed after the attachment sheet 110, the absorbent member 130 and the plurality of release papers 171, The time required for machining can be saved and the positions and sizes of the through holes 117, 137 and 172 and the openings 118, 138 and 173 can be easily matched.

The fixing means 150 includes a fixing means body 151, a fixing portion 154 and a plurality of fastening members 157 and 158. The fixing means body 151 is provided with gripping protrusions 152 and 153 protruding from both sides thereof .

On the other hand, a joining portion 113 is formed on the other surface of the attachment sheet 110. The joining portion 113 is a portion to which the fixing means 150 is fixedly coupled and a part of one surface of the fixing means body 151 is fixedly coupled to the joining portion 113.

The fixing means body 151 may be formed so as to have flexibility or sufficient tensile strength on one side, which is entirely or not fixedly coupled to the abutment portion 113.

The fixing portion 154 is disposed on the fixing means body 151. The fixing portion 154 may be formed integrally with the fixing means body 151 or may be formed on the fixing means body 151 separately manufactured from the fixing means body 151 as shown in FIG.

The fixing part 154 may be made of a material capable of generating a large frictional force when it comes into contact with the outer circumferential surface of the catheter 21. The material of the fixing part 154 may be rubber, have.

The plurality of fastening members 157 and 158 are respectively installed on portions of the other surface of the fixing means body 151 excluding the portion where the fixing portions 154 are disposed. A plurality of fastening protrusions and a plurality of fastening grooves and a pressure-sensitive adhesive or the like are applied to the plurality of fastening members 157 and 158, such as a Velcro, a so-called 'snap button' (157, 158) are contacted with each other and then pressed so that they can be separated from each other.

The operation of the catheter fixing apparatus 100 having the above-described configuration with reference to Figs. 3 and 4 will be described. Fig.

Referring to Fig. 3, the trocar cap 22 of the catheter 21 is inserted into the body through a through hole 11 formed in the skin 10.

At this time, if an external force is applied to the catheter 21, the catheter 21 may be detached from the through hole 11 or the trocar 22 may press other tissues in the body to feel the pain. Particularly, the force applied in the longitudinal direction of the catheter 21 more easily changes the position of the catheter 21, so that special care is required so that a longitudinal external force is not applied to the catheter 21.

In order to prevent such a problem, a portion of the catheter 21 exposed to the outside of the skin 10 excluding the trocar cap 22 is fixed using the catheter fixing device 100. [

First, the catheter fixing device 100 is approached by the catheter 21 and then the catheter 21 is led through the opening 118 to the through hole 117 formed in the middle portion of the attachment sheet main body 111. When the external force is applied to both sides of the opening portion 118, the opening portion 118 is enlarged. Therefore, the catheter 21 and the absorbent member main body 131 are made of the same material, It is possible to easily reach the through hole 117.

Thereafter, the release paper (170 in Fig. 1) is removed from one side of the attachment sheet body 111 and the one side of the attachment sheet body 111 is pressed with a suitable force so as to attach to the skin 10. At this time, although not shown, a portion of the through hole 137 of the absorbing member main body 131 is in contact with a portion where the through hole 11 is formed.

4, after the attachment sheet body 111 is attached to the skin 10 as described above, the catheter 21 is properly bent so that a portion of the catheter 21 abuts against the other surface of the fixing portion 154 .

Thereafter, when one side of the fixing means body 151 is folded as shown and a plurality of fastening members 157 and 158 are fastened together, the fixing portion 154 can be inserted into the catheter 21 Is fixed by means of the fixing means 150.

At this time, when the one side of the fixing means body 151 is moved to the other side as much as possible and then the plurality of fastening members 157 and 158 are fastened, the fixing portion 154 presses the outer peripheral surface of the catheter 21 slightly , The effect of fixing the catheter 21 can be further increased.

As described above, since a large frictional force is applied between the fixing portion 154 and the outer circumferential surface of the catheter 21, the force applied to the catheter 21 in the direction parallel to the longitudinal direction CL1 is transmitted to the fixing means 150, As shown in Fig.

The position of the one side edge (114 in FIG. 1) of the joint 113 is maximally aligned with the longitudinal centerline CL1 of the catheter 21 shown in FIG. 4, And the direction of the center line CL1 may be orthogonal to the longitudinal direction.

This is because the fixing means body 151 is bent at the center axis in the longitudinal center line CL1 of the catheter 21 so that the fastening member 157 provided on one side and the fastening member 158 on the other side are bent .

The width LF of the fixing portion 154 and the position at which the fixing portion 154 is disposed on the fixing means main body 151 are determined by the fixing portion 154 in consideration of the position of the boundary line 114, The area of the other surface of the catheter 21 contacting the outer circumferential surface of the catheter 21 is maximized.

On the other hand, when the catheter 21 is to be removed when the catheter 21 is fixed using the catheter fixing device 100 as described above, the plurality of the holding protrusions 152 and 153 are gripped A force is applied in a direction in which the fastening members 157 and 158 are separated so that the fastening members 157 and 158 are released from the fastened state.

After the fastening members 157 and 158 fastened to each other are separated from each other, the fastening means body 151 is expanded from the bent state as shown in Fig. 4 as shown in Fig. 3, so that the catheter 21 is fixed Can be separated from the means (150).

Thereafter, the catheter 21 can be removed from the skin 10 if the catheter 21 is pulled so that the trocar 22 is pulled out of the through-hole 11.

Immediately after the catheter 21 is removed from the skin 10, exudates such as blood can be discharged through the through-hole 11. [ At this time, if the catheter fixing device 100 is kept attached to the skin 10, the above-described exudates can be absorbed by the absorbent member 130.

In addition, the catheter fixing device 100 is in a state of being attached to the skin 10 so as to cover the through-hole 11 until the skin 10 is regenerated and the through-hole 11 is closed, .

For reference, as described above, the through holes 117 and 137 can be prevented from being formed as needed. When the catheter 21 is removed from the skin 10, the openings 118 and 138 are formed in the attachment sheet main body 111 and the absorbent member main body 131 It is returned to the original position by the flexibility and thus covers the upper side of the through hole 11, so that the protection effect can be increased.

When the width of the openings 118 and 138 is formed to have a minimum width in consideration of the flexibility of the attachment sheet main body 111 and the absorbent member main body 131, Can be further increased.

As described above with reference to FIGS. 1 to 4, the catheter fixing device 100 according to an embodiment of the present invention can securely fix the catheter 21, and the exudate The penetrating hole can be protected against infection, contact with other objects, etc. until the through hole 11 is regenerated and closed after the catheter 21 is removed.

In addition, since the fastening state of the catheter 21 can be easily released if necessary using the holding protrusions 152 and 153, the pain caused to the subject in the process of removing the catheter 21 can be minimized .

On the other hand, when a large amount of exudate flows out from the through-hole 11, the volume of the absorptive member 130 gradually increases as the exudates are absorbed. Accordingly, the thickness of the absorbent member 130 is also increased, so that the space between the attachment sheet main body 111 and the skin 10 is increased.

The distance between the catheter 21 fixed with the fixing means 150 and the skin 10 is gradually increased so that the trocar 22 is gradually moved in the direction of withdrawing from the through hole 11 .

Fig. 5 shows a variant 230 of an absorbent member for preventing this phenomenon.

5, the absorbent member 230 includes an absorbent member main body 231, and the absorbent member main body 231 includes a connecting portion 232 and a pair of absorbent portions 233 and 234.

The connection portion 232 has a shape extending from the end of the opening portion 238 to the edge of the absorbing member main body 231. The pair of absorbing parts 233 and 234 are connected to each other by the connecting part 232 to form the absorbing member main body 231.

The through-hole 237 and the open portion 238 are the same as those of the through-hole 137 and the open portion 138 described above, respectively, and thus description thereof is omitted.

Here, the connecting portion 232 and the absorbing portions 233 and 234 all have flexibility and absorbency, while the connecting portion 232 is made of a material having a lower swelling property than the absorbing portions 233 and 234. For reference, swelling means the extent to which the volume increases when moisture is absorbed.

For example, when the connecting portion 232 is made of a nonwoven fabric or cotton cloth and the absorbing portions 233 and 234 are made of cellulose sponge or superabsorbent resin having relatively high swelling property, The volume of the connection part 232 may be increased to a small extent, but the volume of the absorption parts 233 and 234 may be increased to be greater than that of the connection part 232.

Assuming that the absorbent member 230 is applied instead of the absorbent member 130 of the catheter fixation device 100, the connection 232 may be a catheter (not shown) fixed by the fastening means 150 21 in the longitudinal direction CL1.

Therefore, even if the exudate is absorbed into the absorptive member 230 and the volume thereof is increased, since the connection portion 232 having a low swelling property is disposed between the catheter 21 and the skin 10, the effect of minimizing the change of the position of the catheter 21 Can be obtained.

FIG. 6 is an exploded perspective view of a catheter securing apparatus 300 according to another embodiment of the present invention, and FIG. 7 is a perspective view of the catheter securing apparatus 300 shown in FIG.

6 and 7, the catheter fixing apparatus 300 according to another embodiment of the present invention includes an attachment sheet 310, an absorbent member 330, a fixing unit 350, and a fixing prevention unit 360 do. The present embodiment also includes a release paper (see 170 in FIG. 1), but the description is omitted since it is the same as that described above.

The attachment sheet 310 includes an attachment sheet body 311 and the attachment sheet body 311 is provided with a joint 313, a through hole 317 and an opening 318. [ The attaching seat main body 311, the joining portion 313, the through hole 317 and the opening portion 318 are formed in the above described attachment sheet body (111 in Fig. 1), the joining portion (113 in Fig. 1) And the opening portion (118 in FIG. 1) are the same as those in the first embodiment.

The absorbing member 330 includes an absorbing member main body 331 and the other surface of the absorbing member main body 331 is joined to one surface of the attaching sheet main body 311.

The through hole 337, the extension slit 337a, the opening 338 and the discharge projection 339 are formed in the absorber main body 331. [ The opening portion 338 is formed at a position corresponding to the opening portion 318 of the attachment sheet body 311 and the through hole 337 is also formed at a position corresponding to the position corresponding to the through hole 317 of the attachment sheet body 311 .

The discharge protrusion 339 protrudes from the absorbing member body 331 as shown in FIG. 7. The discharge protrusion 339 protrudes more than the edge of the attachment sheet 310, as shown in FIG. That is, when the attachment sheet body 311 is seated on the skin (see 10 in Fig. 4), the ejection protrusion 339 protrudes more than the edge of the attachment sheet body 311 and is exposed to the outside.

This allows the absorption member 330 to be discharged to the outside through the discharge protrusion 339 when a large amount of exudate is absorbed. The absorption protrusion 339 can be further connected to an absorption means (not shown).

Since the surgeon periodically checks the amount and components of the exudates after the operation in the abdominal cavity is performed, the surgeon can flow the exudate through the discharge protrusion 339 to the outside of the catheter fixing device 300, It can be easily inspected.

The expansion slit 337a assumes a case where the diameter of the catheter 21 is larger than the through hole 337 and can be easily disposed in the through hole 337 even when the catheter 21 has various diameters.

The expansion slit 337a may be formed at the end of the opening 338 when the through hole 337 is not formed so that the catheter 21 is inserted into the end of the opening 338 It can be arranged easily.

For this purpose, the extending slit 337a may be formed in a direction different from the opening 338 as shown, and the number of the extending slits 337a may be plural from one. When a plurality of the extended slits 337a are formed, the catheter 21 may be radially arranged around the end of the opening 338 or the through-hole 337 so that the catheter 21 can be easily disposed.

On the other hand, when the expansion slit 337a is formed in the absorbent member main body 331, as described above, the expansion slit 337a, which has been developed after the catheter 21 is pulled out from the through hole 11 and removed, And is returned to the original state by the elasticity of the material constituting the main body 331. [ Therefore, the effect of reducing the diameter of the through hole 337 and covering the through hole 11 can be obtained.

The fixing means 350 includes a fixing means body 351, a fixing portion 354 and a plurality of fastening members 357 and 358. Here, the fixing means body 351, the fixing portion 354 and the plurality of fastening members 357 and 358 are provided with the fixing means body 151, the fixing portion 154, The members 157 and 158 are the same as those of the members 157 and 158, and a description thereof will be omitted.

However, a plurality of fixing protrusions 355 protrude from the surface of the fixing portion 354. [

The fixing protrusion 355 allows strong frictional force to act between the outer peripheral surface of the catheter 21 and the fixing portion 354 when the catheter 21 is fixed by the fixing means 350, So as to further improve the effect of fixing the fluid to not flow.

Although not shown in detail, the fixing protrusions 355 may be evenly distributed on the surface of the fixing portion 354, and may be arranged in a partially assembled form if necessary.

This is a two-way catheter having a balloon which is inflated at its end to be fixed in the human body, unlike the catheter 21 shown in the drawing, or a three-tube catheter 3 way catheter. In the case where the catheter of this type is fixed by the fixing means 350, the arrangement of the fixing protrusions 355 may be correspondingly changed.

The anti-collision means 360 is disposed at a position in contact with the intermediate portion of one surface of the absorbing member 330, that is, the through hole 11.

The anti-collision means 360 includes a collision preventing main body 361, and a through hole 367 and an incision 368 are formed in the collision preventing means main body 361. The through hole 367 is formed in a size corresponding to the position corresponding to the through holes 317 and 337 and the cutout 368 is formed at a position corresponding to the openings 318 and 338 described above.

The collision preventing means 360 can prevent the collapsing of the absorbent member 330 by the exudates flowing out from the through hole 11 and absorb the catheter supporting device 300 from the through hole 11 when the catheter supporting device 300 is to be separated from the skin 10. [ This is to prevent a case where a separate treatment for separating the member 330 is required.

For this, the main body 361 of the anti-collision means may be formed as a network structure so that the exudates can smoothly pass through. The material of the anti-collision means 361 is flexible and nonabsorbent like polyethylene or silicone, Which does not contain a component that adversely affects the environment.

The anti-collision means 360 is disposed between the through-hole 11 and the absorbing member 330 so that the absorbing member 330 is not stuck to the through-hole 11.

The cover sheets 381 and 382 indicated by dotted lines in Fig. 7 are used to seal the opening 318 or to prevent the edge portions of the absorbing member main body 331 from being exposed between the attachment sheet body 311 and the skin 10. [ Or when the adhesive force between the attachment sheet body 311 and the skin 10 is insufficient.

That is, as described above, the catheter 21 may be detached from the skin 10, and then the catheter fixing device 300 may remain on the skin 10 to prevent infection of the through-hole 11, 21 are inserted into the long-term through-holes 11, the adhesive force between one surface of the attachment sheet main body 311 and the skin 10 may be weakened.

For this purpose, the cover sheets 381 and 382 can be joined to the boundary portion of the skin 10 with the through hole 317 and the opening 318 or between the attachment sheet body 311 and the skin.

When the catheter fixing device 300 is used to cover the long-term through-hole 11, the exudate absorbed by the absorbing member 330 may be corrupted or contaminated by foreign substances introduced from the outside, Infection may occur.

To prevent this, the absorptive member 330 may include an antibiotic or bactericide to prevent the propagation of bacteria in the absorbed exudate.

Fig. 8 is an exploded perspective view for explaining a modification of the fixing means shown in Fig. 1, and Fig. 9 is an enlarged view of a portion indicated by A in Fig.

8 and 9, the fixing means 450 includes a fixing means body 451, a fixing portion 454, and a plurality of fastening members 457 and 458. Here, the fixing portion 454 and the plurality of fastening members 457 and 458 are the same as those of the fixing portion 154 and the plurality of fastening members 157 and 158 described with reference to Figs. 1 and 2, do.

The one-way flexible portion 452 is formed in the fixing means body 451.

The one-sided flexible portion 452 may be formed on one side of the fixing means body 451 or on the entirety of the fixing means body 451, as shown in the figure.

Here, the one-sided flexible portion 452 has flexibility only in a specific direction, and the direction parallel to the longitudinal direction CL1 of the catheter 21 shown in Fig. 4 is the central axis, and the one-sided flexible portion 452 Has flexibility only in the direction in which it is rotated with respect to the central axis.

That is, this characteristic of the one-sided flexible portion 452 can be realized by forming a plurality of grooves 453 in parallel in the fixing means body 451 as shown in Fig. The longitudinal direction CL2 of the plurality of grooves 453 is parallel to the longitudinal direction CL1 of the catheter 21 fixed by the fixing portion 450. [

Thus, the one-sided flexible portion 452 can be bent with only the direction CL2 parallel to the plurality of grooves 453 as the rotation axis, so that the fixing means 450 is deformed only in the direction of fixing and releasing the catheter 21 .

Therefore, the fixing means 450 does not deform the catheter 21 against an external force applied in various directions other than the direction parallel to the longitudinal direction CL1, so that the catheter 21 can be more firmly fixed.

Fig. 10 is an exploded perspective view for explaining a modified example 452a of the one-sided flexible portion shown in Fig.

Referring to Fig. 10, a plurality of posterior pieces 453a and a plurality of thin pieces 453b are alternately arranged in the one-sided flexible portion 452a formed in the fixing means body 451a. The longitudinal direction CL3 of the plurality of pieces 453a and the plurality of pieces 453b is parallel to the longitudinal direction CL1 of the catheter 21 and the longitudinal direction CL2 of the groove 453 described with reference to Fig. .

For reference, the succeeding piece 453a means a thicker portion than the periphery, and the thin piece 453b means a thinner portion than the periphery.

Therefore, the one-sided flexible portion 452a can be bent only in the direction of the rotation axis of the longitudinal piece CL3 of the posterior piece 453a or the thin piece 453b, and in the other direction, As shown in Fig.

In the present specification, 'parallelism' and 'orthogonal' in the present specification do not mean mathematical 'parallelism' and 'orthogonal' but refer to 'parallelism' and 'orthogonalism', taking into account various errors such as machining error, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Other embodiments may easily be suggested by adding, changing, deleting, adding, or the like of components, but these are also within the scope of the present invention.
