Description

  The present invention relates to a catheter tie wrapped around a subject's forearm to secure at least one of the subject's wrist or elbow.

For example, in order to perform contrast examinations on various parts of a human body, a catheter is punctured through a radial artery, a brachial artery, a femoral artery, etc., and a contrast agent is injected. Then, when the contrast examination is completed, the catheter will be removed, but after the removal, a puncture part for hemostasis is used by using a hemostatic device such as those of Patent Document 1, Non-patent Document 1 and Non-patent Document 2, for example. Must be squeezed for 3 to 4 hours. At this time, the elbows and wrists must be fixed so that they do not bend.
Further, not only after the catheter is removed, but also when the catheter is punctured in the radial artery or the brachial artery, the elbow and wrist must be fixed so that they cannot be bent.

  In order to fix the elbows and wrists so as not to bend, various cines have been considered. The pressure haemostatic / cinema (arterial occluder / splint) of Patent Document 2 is concave so that a wrist splint made of a rigid material such as PVC accommodates the arm and extends from the forearm to the back of the hand. Both ends are attached to the forearm and hand by straps. This keeps the wrist from bending. In addition, a pressure pad is provided on the forearm strap to locally compress the radial artery. At this time, blood flows in the ulnar artery without being compressed.

  As shown in FIG. 5, in the cine of Patent Document 3, a styrofoam joint suppressor formed to be curved to accommodate an arm extends from the upper arm to the hand, and four fingers are joint suppressors. Then, the upper arm side of the joint restraint is attached to the upper arm with a binding band. This keeps the elbow from bending.

  As shown in FIG. 1, in the cine of Patent Document 4, a gutter-shaped fixing plate that is a hard material made of wood or resin and that easily fits the skin surface extends in front of and behind the elbow, and both ends thereof are attached to the arm by bands. It is attached. This keeps the elbow from bending.

  The compression hemostatic / cinema of Non-Patent Document 3 is a commercially available product for wrists, and a slightly curved fixing plate made of synthetic resin extends in front of and behind the wrist. A plurality of reinforcing ribs are formed in the extending direction, and both ends of the fixing plate are attached to the forearm and the hand by bands. This keeps the wrist from bending. And a separate hemostatic device is attached.

  However, the cines of Patent Documents 2 to 4 and Non-Patent Document 3 are made of a hard material in which the fixing portion for fixing the wrist and elbow so as not to bend cannot be freely deformed. Therefore, there is a problem that the same cine does not fit as it is to a target person having different arm thicknesses such as a fat person and a thin person, or a target person having different extension such as an adult and a child. For this reason, in order to apply it to different subjects, it is necessary to prepare a plurality of sizes of cine in advance, or to add an adapter for adjusting to fit the foot.

  Further, the conventional cine has not been made based on the idea that one cine can be used for both wrist fixing and elbow fixing, such as wrist fixing or elbow fixing.

  In addition, when preparing multiple cines, since the cines themselves have a specified shape, it is not possible to stack multiple cines easily and there is also the problem that they will be bulky when stored. is there.

  Further, the conventional cine is expensive because it requires a die cost for a fixed portion for injection molding. For example, it costs about 10,000 yen for fixing the wrist and about 12,000 yen for fixing the elbow.

  Moreover, since the conventional cine is expensive, most of it is reused. Blood may adhere to the cine, so it must be sterilized before reuse. This disinfection work is very troublesome. Also, if there is a mistake in the disinfection work, it will be an irreversible trouble. In addition, if it is reused many times, there is a risk of deterioration or breakage of the seane, and the seane due to such a change over time is unsightly and does not have a clean feeling. Thus, reuse of cine creates many problems.

  Further, the conventional seane has a structure in which all the fixing parts are supported on the lower side of the arm, but there is also a problem that blood is likely to diffuse if bleeding occurs during hemostasis.

  Therefore, an object of the present invention is to provide a catheter cine that can be easily fitted by different subjects without preparing a plurality of different catheter cines in advance. Another object of the present invention is to provide an inexpensive catheter cine that does not need to be reused. Further, it is an object of the present invention to provide a catheter cine in which blood is less diffused even when bleeding occurs during hemostasis.

  In order to solve the above-mentioned problems, a catheter cine according to one aspect of the present invention is wrapped around a forearm of a subject, and a seat portion for fixing at least one of a subject's wrist or elbow, and the above-mentioned wound around the forearm. And a fixing portion for fixing the seat portion.

As a result, as compared with the conventional rigid seane, the catheter seam of the present application is in the form of a sheet that is wrapped around the arm, so that it can be easily fitted to arms having different sizes. Further, since it is in the form of a sheet, it is possible to stack a plurality of catheter sheathes on top of each other, and it is possible to store a plurality of catheter sheathes without being bulky during storage. Further, since the seat portion is wound, it is not necessary to care about the size of the object to be wound, and the seat portion can be used for fixing the wrist or the elbow. Further, since the structure is wrapped, even if bleeding occurs during hemostasis, the diffusion of blood can be suppressed. In addition, since the wound seat portion is difficult to bend in the extending direction of the arm, bending of the wrist or elbow can be firmly prevented.
Moreover, in the catheter sheath of the present invention, it is preferable that the sheet portion includes a corrugated cardboard including a core and a front liner.

Since the seat portion is made of cardboard, which is a paper material, the catheter cine can be provided at low cost. For this reason, since it can be disposable, it is sanitary without reuse, and disinfection work after use is unnecessary. Also, since it is a paper material, it can be easily cut. Further, the sheet portion can be changed into a desired shape by cutting. In addition, it is easy to write letters on the front liner. For example, a ball-point pen can be used to fill in items to be sent such as the end time of hemostasis.
Further, in the catheter sheath of the present invention, it is preferable that the sheet portion includes a water-absorbent sheet on the skin side of the user.

As a result, blood that has leaked during hemostasis can be absorbed, thus preventing the diffusion of blood. Therefore, it is possible to prevent the surroundings from being contaminated by blood and reduce the amount of cleaning around.
Further, in the catheter sheath of the present invention, it is preferable that the sheet portion is provided with cutting perforations.

Thereby, the perforation for the opening hole of the puncture portion, the perforation for the insertion holes of the left and right thumbs, the perforation for adjusting the winding length, the perforation for the total length adjustment, and the removal for the description will be made in the embodiment below. By providing perforations, etc., the user can easily cut the sheet portion.
Further, in the catheter cine according to the present invention, it is preferable that the seat portion is provided with an opening hole of a puncture portion and insertion holes of left and right thumbs.

As a result, the opening hole of the puncture portion and the insertion holes of the left and right thumbs that are often used and do not cause any trouble even if they are provided from the beginning are provided, so that the user can save the labor of opening the holes. .. Further, by inserting the thumb into the hole and fixing the thumb, it is possible to prevent the forearm from performing pronation or supination movement to move the muscle around the puncture portion and open the puncture portion.
In addition, the catheter sheath of the present invention preferably includes a splint for fixing at least one of the wrist or the elbow of the subject.
As a result, the bending of the wrist or elbow can be prevented more strongly. For example, it can prevent bleeding in children who are unable to follow the caregiver's attention.

In addition, in each drawing used for the description in this specification, in order to make each member a size that can be recognized in the drawing, each member is shown in a different scale, and is not necessarily shown. It is not displayed in proportion to the size of.

[First Embodiment]
The catheter sheathe 100 of the first embodiment will be described with reference to FIGS. The catheter seane 100 is a seane (fixing device) that fixes the joints of the wrist A1 and elbow A2 so as not to bend during hemostasis of the artery after the catheter inspection. The catheter cine 100 includes a sheet-like sheet portion 1 wound around the hand A3, a forearm A4 or an upper arm A5 of a subject (examinee) to be subjected to a catheter inspection, and two fixing portions 2 for fixing the wound sheet portion 1. Consists of.

As shown in FIGS. 1A and 1B, the seat portion 1 includes a corrugated cardboard 11 including a front liner 111 and a core 112, a cushion 12 corresponding to a back liner, and a water absorbing portion 13.
The front liner 111 that constitutes the corrugated board 11 is made of white paper on which letters can be easily written. Also,
The core 112 that constitutes the corrugated board 11 is, for example, a common corrugated board made of paper such as a material of K120 and a wave of C flute.

  The D1 direction in FIG. 1A is the winding direction of the sheet portion 1. Then, the D1 direction coincides with the flow direction of the machine forming the corrugation. Therefore, the corrugated board 11 is very easily bent in the winding direction D1.

  Further, in FIG. 1A, the D2 direction is the extending direction of the seat portion 1 that coincides with the extending direction of the forearm A4 and the upper arm A5, and is orthogonal to the winding direction D1. The extending direction D2 coincides with the width direction (eye direction) of the corrugated board 11. Therefore, the corrugated board 11 is difficult to bend in the extending direction D2.

  The cushion 12 is a foamed foam sheet material made of soft plastics used as a cushioning agent or the like, and is bonded to the core 112. The water absorbing portion 13 is soft and has water absorbing properties such as Japanese paper and tissue paper, and is adhered to the cushion 12.

  The seat portion 1 has a sheet shape, and since the cushion 12 and the water absorbing portion 13 are very soft, they easily bend in the winding direction D1 opposite to the front liner 111. Further, since the sheet portion 1 is made of paper or a soft foam plastic material, it can be easily cut with scissors or a cutter knife.

  Since the sheet portion 1 can be easily cut, it has a larger size and is used by cutting it to a size desired by a user such as a doctor or a nurse. In addition, since the holes such as the opening hole 14 through which the main part of the hemostatic device S shown in FIG. 2 and the insertion hole 15 into which the thumb A6 is inserted are configured to be opened by the user, the first embodiment The seat portion 1 of is not initially opened.

  The two fixing parts 2 are common parts. The fixing portion 2 includes a belt 21, a loop surface 22 of a surface fastener and a hook surface 23 of the surface fastener which form a holding portion. The belt 21 is made of a sturdy material having a rectangular shape that is sufficiently longer than the length around the arm of a general person. The loop surface 22 of the surface fastener is formed by being attached to one surface of the belt 21 on the front end side. The loop surface 22 is also called a female surface or a B surface, and a looped loop is formed by stitching outer threads. The hook surface 23 of the hook-and-loop fastener is formed by being attached to the other surface of the belt 21. The hook surface 23 is also called a male surface or an A surface, and a key-like hook is formed by sewing an outer thread.

  Then, the fixing portion 2 is wound by winding the belt 21 around the seat portion 1, the loop surface 22 and the hook surface 23 are aligned, and the loop of the loop surface 22 is hooked by the hook of the hook surface 23 to be engaged. The seat portion 1 is fixed.

  As shown in FIG. 1B, the belt 21 has the surface on which the loop surface 22 is formed fixed to the front liner 111 of the seat portion 1 by adhesion, stitching by stitching or the like.

[Use Example 1]
A usage example 1 will be described with reference to FIGS. 2 and 3. Use example 1 is a use example for fixing a wrist. Specifically, the catheter sheathe 100 of the first embodiment is cut and used for fixing the right wrist A1. Note that the dashed diagonal lines in FIG. 2A indicate the portions cut from the sheet portion 1 of the first embodiment.

  The seat portion 1A of the usage example 1 is formed by cutting the seat portion 1 of the first embodiment. Specifically, the sheet portion 1 is cut so that the length in the winding direction D1 is suitable for winding around the hand A3 or the forearm A4, and the length in the extending direction D2 is slightly longer for the finger A7. The sheet portion 1 is cut to a visible length. Further, the opening hole 14 is cut from the sheet portion 1 so that the pressing portion S1 which is a main portion of the hemostatic device S for the radial artery C1 is exposed. Further, the insertion hole 15 is cut from the sheet portion 1 so that the thumb A6 is fitted therein.

  By this cutting, the catheter sheathe 100 of the first embodiment becomes the catheter sheathe 100A of the first use example. In addition, the seat portion 1 of the first embodiment is the seat portion 1A of the usage example 1.

  In addition, these cutting | disconnections are cut | disconnected by the minimum size so that the intensity | strength of 100 A of catheter cine may not fall. Further, when the belt 21 of the fixed portion 2 is too long, the belt 21 may be cut to adjust the length.

  Then, as shown in FIG. 2B, the catheter sheath 100A has a right hand A3 such that the thumb A6 is exposed from the insertion hole 15 and the pressing portion S1 and the air injection portion S2 of the hemostatic device S are exposed from the opening hole 14. And wrapped around the forearm A4. At this time, as shown in FIG. 3B, the loop surface 22 at the tip of the belt 21 that has rotated around the fixing portion 2 is joined to the hook surface 23, and the seat portion 1A is fixed.

  Since the extending direction D2 of the seat portion 1A and the extending direction of the forearm A4 of the wound catheter sheath 100A coincide with the extending direction of the forearm A4, the catheter sheath 100A is difficult to bend and the wrist A1 can be prevented from bending.

  In addition, as shown in FIG. 3A, the pressing portion S1 of the hemostatic device S is inflated by air pressure and protrudes to the side opposite to the rigid support plate S3 to locally compress the radial artery C1 near the radial bone B1. At this time, since the ulnar artery C2 near the ulna B2 is not compressed, the blood flow in the ulnar artery C2 is not disturbed.

[Use Example 2]
A usage example 2 will be described with reference to FIG. Use example 2 is a use example for fixing an elbow. Specifically, the catheter sheathe 100 of the first embodiment is cut and used for fixing the right elbow A2. In addition, the dashed diagonal line of FIG. 4A shows the portion cut from the sheet portion 1 of the first embodiment.

  The seat portion 1B of the usage example 2 is also formed by cutting the seat portion 1 of the first embodiment. Specifically, the sheet portion 1 is cut to have a length in the winding direction D1 that is suitable for winding around the forearm A4 or the upper arm A5. Further, the opening hole 14B is cut from the sheet portion 1 so that the pressing portion, which is a main portion of the hemostatic device SB for the brachial artery, is exposed.

  By this cutting, the catheter sheathe 100 of the first embodiment becomes the catheter sheathe 100B of the second use example. The seat portion 1 of the first embodiment is the seat portion 1B of the second usage example.

  Then, as shown in FIG. 4B, the catheter cine 100B is wrapped around the right forearm A4 and upper arm A5 so that the pressing portion S1 and the air injecting portion S2B of the hemostatic device SB are exposed. At this time, the seat portion 1B is fixed by the fixing portion 2.

  As described above in Use Example 1 and Use Example 2, the easily severable sheet-shaped cine 100 for catheters of the first embodiment is appropriately cut to be used as in Use Example 1. For fixing A1 and for fixing the arm A2 as in Use Example 2, both can be appropriately fitted and shared.

  In addition, the catheter lining 100 can be commonly used by fitting it to persons having different arm thicknesses such as a fat person and a thin person, and persons having different extensions such as an adult and a child. Further, by cutting the sizes of the opening holes 14 and 14B in accordance with the sizes of the hemostatic instruments S and SB, the catheter sheath 100 can be commonly used for the hemostatic instruments S and SB having different sizes. As described above, since the catheter sheathe 100 of the first embodiment can be commonly used in various fields, it is not necessary to stock a plurality of catheter sheathes 100 having different sizes and holes.

Further, since the catheter tie 100 has a configuration in which the seat portion 1 is wound and used, it is not necessary to care about the size of the object to be wound, and can be used for both wrist fixing and elbow fixing. It can fit fat and thin people. Further, since the sheet portion 1 is wound, even if bleeding occurs during hemostasis, the diffusion of blood can be suppressed. Since the wound seat portion 1 is hard to bend in the extension direction D2 of the arm, bending of the wrist or elbow can be prevented more firmly than in the conventional case.
Further, since the catheter cine 100 is in the form of a sheet, it can be stored without being bulky during storage.

  Further, the base material of the catheter sheath 100 is the corrugated board 11, which is inexpensive. For this reason, since the catheter sheath 100 can be disposable, it is sanitary without being reused, and disinfection work of the catheter sheath 100 after use is unnecessary.

  Further, since the front liner 111 is a paper material, it is easy to write characters directly with a ballpoint pen, pencil, or the like. Therefore, it is possible to write the notification items such as the hemostasis end time on the surface of the catheter lining 100. In particular, since the catheter seane 100 has a configuration in which the sheet portion 1 is wound around, the items to be posted on the front liner 111 are very easy to visually recognize.

  Moreover, since the inner surface of the catheter cine 100 that comes into contact with the skin is the water-absorbing portion 13 that has water-absorbing properties, it is possible to absorb the leaked blood. In addition, since a soft cushion is provided between the water absorbing portion 13 and the center core 111, it is comfortable to wear.

  The corrugated cardboard 11 is made of a paper material, but the material is not limited to this. For example, a sheet-shaped material that easily bends in the D1 direction and easily bends in the D2 direction, for example, a material such as a roll screen, It easily fits on A4 and can fix wrist A1 and elbow A2.

[Second Embodiment]
Next, with reference to FIG. 5A, a catheter sheath 100C according to the second embodiment will be described. The catheter sheath 100C of the second embodiment is made of the same material as the catheter sheath 100 of the first embodiment. On the other hand, the catheter sheath 100C has an opening hole 14C for both the hemostatic device S for the radial artery C1 and the hemostatic device SB for the brachial artery, and two insertion holes 15C into which the thumb A6 is inserted. And so on.

  Regarding the portion of the insertion hole 15C, the cushion 12 and the water absorbing portion 13 (both not shown) that form the seat portion 1C are not through holes but only cross-shaped cuts 151C. This notch 151C prevents the skin of the insertion hole 15C from being exposed by the cushion 12 and the water absorbing portion 13 when the thumb A6 is not inserted.

[Use Example 3]
Use example 3 will be described with reference to FIGS. 5B, 6A, and 6B. Use example 3 is a use example for fixing a wrist. Specifically, the seat portion 1C of the catheter sheath 100C of the second embodiment is cut and used as the fixation of the right wrist A1. Note that the dashed diagonal lines in FIG. 5B indicate the cut portions of the seat portion 1C of the second embodiment. The length of the sheet portion 1D obtained by cutting the sheet portion 1C in the winding direction D1 is cut to a length suitable for winding around the hand A3 or the forearm A4.

  FIG. 6A is an image showing the state of the hand A3 and the forearm A4 before the catheter cine 100D is attached, and the hemostatic device S for the radial artery C1 is attached. As shown in FIG. 6B, the sheet portion 1D of the partially cut catheter cine 100D is wrapped around the right hand A3 and the forearm A4 with the thumb A6 and the main part of the hemostatic device S exposed, and then the two It is fixed by the fixing portion 2.

  Since the extending direction D2 of the seat portion 1D in the wound state coincides with the extending direction of the forearm A4, the catheter sheath 100D is difficult to bend, and bending of the wrist A1 can be prevented. At this time, the insertion hole 15C for the left thumb A6 of the catheter case 100D of Use Example 3 is not used, but there is no problem in fixing the wrist A1.

[Use Example 4]
The use example 4 will be described with reference to FIGS. 5B, 7A, and 7B. Use example 4 is a use example for fixing an elbow. Specifically, the seat portion 1C of the catheter sheath 100C of the second embodiment is cut and used for fixing the right elbow A2. In this use example, the catheter cine 100D of the third use example of FIG. 5B is used as it is as Use Example 4.

  FIG. 7A is an image showing the state of the forearm A4 and the upper arm A5 before the catheter cine 100D is attached, and the hemostatic device SB for the brachial artery C2 is attached. As shown in FIG. 7B, the sheet portion 1D of the catheter cine 100D is wound around the right forearm A4 and the upper arm A5 with the main portion of the hemostatic device SB exposed, and is fixed by the two fixing portions 2.

  Since the extending direction D2 of the seat portion 1D in the wound state coincides with the extending direction of the forearm A4, the catheter sheath 100D is difficult to bend, and bending of the elbow A2 can be prevented. At this time, the two insertion holes 15C for the thumb A6 of the catheter sheath 100D of Use Example 4 are not used, but there is no problem in fixing the elbow A2.

  As described above, as shown in the usage example 3 and the usage example 4, the catheter cine 100C according to the second embodiment only needs to adjust the length in the winding direction D1 according to the thickness of the upper arm A5 of the target person, and thereby the wrist A1. It can be commonly used to fix the arm and the elbow A2.

  Further, although the existing opening hole 14C of the second embodiment is used for both the radial artery C1 and the brachial artery C2, a dedicated opening hole 14C may be provided for each. At this time, the sheet portion 1C that is long in the extending direction D2 is set, and the user can cut and use the sheet portion 1C.

[Third Embodiment]
A catheter sheathe 100E according to the third embodiment will be described with reference to FIG. The catheter sheath 100E is the catheter sheath 100 of the first embodiment provided with various perforations 16. The perforations 16 are for easily cutting the sheet portion 1E. As shown in FIG. 8, four types of perforations 16 for cutting are provided.

  Specifically, one is four perforations provided in a direction parallel to the extending direction D2 for adjusting the length when the sheet portion 1E is wound. The other is two perforations provided in a direction parallel to the winding direction D1 in order to adjust the length of the catheter sheath 100E in the forearm A4 direction. The other is a perforation for opening holes of two sizes, large and small, for exposing the hemostatic device S for the radial artery C1 or the hemostatic device SB for the brachial artery. The other is a perforation for an insertion hole into which the left or right thumb is inserted.

Then, the user can easily cut the sheet portion 1E by appropriately selecting and cutting these perforations 16, and realize the catheter cine 100E of various sizes according to the object. it can.
It should be noted that the sheet portion 1E can be easily cut with scissors or a cutter knife even if the mark is a printed line such as a cut line instead of the perforated line as in the present embodiment.

[Fourth Embodiment]
The catheter cine 100F according to the fourth embodiment will be described with reference to FIG. 9A. The catheter sheath 100F is obtained by adding the accessory splint 3 to the catheter sheath 100A shown in the first embodiment and the like.

  The splint 3 is made of a hard rod such as resin or metal. The wrist A1 and elbow A2 can be more firmly fixed by the splint 3. For example, a child or the like who has difficulty keeping the care of the caregiver may suddenly bend his wrist or elbow. In such a case, a very strong force is applied to the catheter lining 100F, but by adding the splint 3 of the present embodiment, bending of the wrist or elbow can be prevented and bleeding can be prevented. You can

The splint 3 may be attached to the catheter cine 100F from the beginning, but is preferably detachable so that it can be attached by the subject. In the case of this detachable structure, for example, a structure in which a bag-shaped insertion portion into which the splint 3 can be inserted is provided in the seat portion 1F can be adopted.
Further, the splint 3 is provided so as to be located under the arm when the catheter cine 100F is used.
