Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an angiographic drape used for angiographic examination, and more specifically, safely cuts a portion covering a patient's face by hand cutting without using a knife such as scissors. In addition, the present invention relates to a drape for angiography examination having a versatility having openings at positions corresponding to almost all puncture sites (groin, clavicle, elbow, wrist and neck).
[0002]
[Prior art]
In general, a surgical drape that covers the patient and exposes only the puncture site during surgery is used. Surgical drape is used for the purpose of keeping the patient warm and keeping the surface side (the practitioner side) clean, as well as preventing people and peripheral devices from being contaminated by blood and various chemicals from the patient. For example, an absorptive and heat-insulating sheet material such as a nonwoven fabric is used. An example of this conventional example is Patent Document 1.
[0003]
By the way, since the position of the opening of the inspection drape differs depending on the type and part of the examination and treatment, the doctor selects and uses the drape according to the type of examination and treatment.
[0004]
For example, an angiography (angio) used for the treatment of an aneurysm or myocardial infarction will be described. For angiography, a sheath and a catheter inserted into an arteriovenous vein are used. Usually, a sheath is inserted from a site where relatively thick blood vessels such as the groin, clavicle, and arm flow, but a doctor inserts a catheter depending on the thickness of the sheath and catheter and the patient's condition. A site is selected and the patient is treated using a surgical drape having an opening corresponding to the puncture site.

[Problems to be solved by the invention]
By the way, in the conventional angiography drape , in order to ensure the patient's breathing and remove as much discomfort as possible, the practitioner opens the part that covers the patient's face using a knife such as scissors before the examination. While you are in, to open up the, not only require a careful work, patients have become nervous in the previous inspection, there is a possibility that embrace the further fear to see the knife.
[0007]
In angiographic examinations , blood vessels often flow out immediately after the start of insertion or after removal because blood vessels are damaged by the catheter. In particular, since the inguinal part has the largest blood vessel, a large amount of blood flows out, and a drape characteristic that can reliably absorb and collect blood is desired in the inguinal part.
[0008]
Therefore , an object of the present invention is to perform an angiography examination in which a portion covering the face portion of a patient can be cut open without using a blade such as scissors, and the surroundings are prevented from being contaminated as much as possible by blood that has flowed out. To provide a drape.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has a base sheet made of a non-woven fabric having a surface side (treatment side) as a liquid absorbing surface and a back side (patient side) as a waterproof surface. The sheet is provided with an opening for exposing the patient's puncture site on the back side to the surface side, and the sheath and the angiographic catheter are inserted from the opening toward the puncture site. In a drape for angiography examination used at the time, a slit made of a continuous cut for exposing a patient's face is formed at a predetermined position of the base sheet, and the slit is cut when not in use. It is characterized by being connected through a waterproof adhesive tape having hand cutting properties over the entire length .
[0010]
According to this, when exposing the patient's face, since the slit can be opened by hand without using a cutting tool such as a blade, it can be concentrated on the subsequent treatment without causing the patient's anxiety, The efficiency of medical work can be improved. Here, “hand cutting” means a characteristic that can be easily torn by hand without using a cutting tool such as a cutter or scissors.
[0011]
In the present invention, the slit preferably includes three slits: a center slit along the center of the patient's face and a pair of side slits provided symmetrically across the center slit. .
[0012]
According to this, when the sheath is inserted from the opening facing the puncture site of the groin, elbow, and wrist, the center slit is opened to expose the patient's head , and the clavicle, neck of when penetrating the sheath and catheter from the opening corresponding to the puncture site, by opening the anti-penetration side of the side slits, e given a feeling of opening to the patient, mental burden on the patient Can be reduced.
[0013]
The liquid absorbing surfaces are folded at both ends in the width direction of the base sheet so as to face each other, and a pocket part is formed by adhering a part of them to each other. It can be stopped at the part, and contamination to the floor can be prevented.
[0014]
When a sheath is inserted into the groin, or when a procedure shifts from examination to treatment, a large amount of bleeding is expected, so the periphery of the opening corresponding to the groin of the base sheet is It is preferable that a high-absorbency sheet having better liquid absorbency than the base sheet is further provided. Here, when one of the openings corresponding to the inguinal portion is in use, it is preferable that the other is closed with the superabsorbent sheet.
[0015]
More preferably, the superabsorbent sheet has a substantially central portion fixed to the base sheet, and both end sides thereof are preferably not fixed to the base sheet. When the sheath is inserted, both arms are placed so that they are straight along the core, so that the swelling of the arms lifts both sides of the superabsorbent sheet and builds a weir, so that blood flows down Can be effectively prevented. Further, it can be used in the same manner when a catheter is operated by inserting a sheath from a hand (elbow or wrist).
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an angiographic examination drape according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view taken along the line AA.
[0017]
This drape 1 for angiography examination (hereinafter simply abbreviated as “drape 1”) includes a rectangular base sheet 2, and the base sheet 2 has openings 3 for exposing each puncture site of the patient H. A plurality are provided.
[0018]
The base sheet 2 is made of a substrate having liquid absorbency such as a nonwoven fabric, and is formed in a size that can be completely covered even at least by the patient H with both hands extended to 180 degrees. In this embodiment, it is approximately 3200 mm long × 2100 mm wide. In addition, about the material and form of the base sheet 2, it can select suitably according to a specification.
[0019]
In this example, the base sheet 2 is waterproofed by resin coating on the back side (patient side). Waterproofing of the base sheet 2, for example, on the back side of the nonwoven fabric may be adhered to the resin sheet, but becomes waterproof coating, but it may also be so further adhering the like nonwoven fabric over the Nari waterproof resin sheet.
[0020]
A part of the base sheet 2 is provided with a see-through unit 21 for operating an operation panel of an angiographic apparatus (not shown) and for visually observing the condition of the patient H covered with the drape 1.
[0021]
The see-through portion 21 is made of, for example, a transparent resin sheet. In this example, the see-through portion 21 is provided in a rectangular shape (approximately 1700 mm long × 850 mm wide) at the lower left end portion of the base sheet 2. The transparent portion 21 is formed by integrally forming a resin sheet on the base sheet 2 from which a portion corresponding to the transparent portion 21 has been cut out in advance by heat sealing or adhesion.
[0022]
Referring also to FIG. 2, both ends of the base sheet 2 in the width direction (left and right ends in FIGS. 1 and 2) are folded so that the liquid absorption surfaces on the surface side face each other, and some of them are The pocket portions 22 and 22 are formed by being fixed to each other.
[0023]
In this example, the pocket portions 22 and 22 are bent at a position of about 50 to 100 mm from both ends of the base sheet 2, and about 25 mm from the bent position are fixed by heat sealing, The portion of 25 to 75 mm is not fixed. Further, both ends (upper and lower ends in FIG. 1) of the pocket portions 22 and 22 in the longitudinal direction are also fixed by heat sealing.
[0024]
According to this, since the bent portion is formed in a pocket shape, even if the non-fixed portion is lifted from the base sheet 2 and a large amount of liquid flows out when used, it is reliably received by the pocket portions 22 and 22. Can do.
[0025]
A center slit 23 for exposing the face of the patient H is provided at the center of the upper end side (upper side in FIG. 1) of the base sheet 2, and the center slit 23 is sandwiched on both sides of the center slit 23. In this example, the pair of side slits 24a and 24b are provided symmetrically.
[0026]
The center slit 23 and the side slits 24a and 24b are formed by continuous cuts formed in the base sheet 2 in advance. As shown in FIG. 4, when not in use, the cuts are provided via an adhesive tape 25 having hand cutting properties. It is connected. Moreover, it is preferable that the adhesive tape 25 is waterproof, and according to this, it is possible to prevent liquid from entering from the unused slits 23 and 24.
[0027]
In this example, the pressure-sensitive adhesive tape 25 is a pressure-sensitive adhesive tape (eg, “Alporin” manufactured by Taketora Co., Ltd.) provided with a hand-cut property by providing a number of minute holes in a polyethylene film. If there is an adhesive tape having hand cutting properties (hand cut), it can be appropriately selected. In addition, hand cutting property means the characteristic which can be easily torn with a hand, without using cutting tools, such as a cutter and scissors.
[0028]
In this example, the center slit 23 is formed with a length of about 500 mm from the center of the upper end of the base sheet 2, and both side slits 23 a and 23 b are the same as the center slit 23 with a distance of 300 mm from the center slit 23 to the left and right. It is formed with a length.
[0029]
In this example, the center slit 23 is constituted by a simple straight slit, but other than this, for example, as shown in FIG. 5A, it may be formed in a V shape, or FIG. As shown in b), it may be formed in a Y shape.
[0030]
According to this, when the openings 31a, 31b, 33a, 33b, 34a, 34b of the groin part, elbow part, and wrist part described later are used, the center slit 23 is cut and the head of the patient H is exposed. Can reduce the mental burden on the patient H. Moreover, when using the opening parts 32a and 32b of the clavicle part or the neck part, the breathing of the patient H can be ensured by cutting any one of the side slits 24, and the discomfort can be removed.
[0031]
Next, referring to FIG. 1 again, the configuration and position of the opening 3 will be described. The openings 3 are opened in a total of eight locations as left and right pairs at positions where the groin portion, clavicle portion (or neck portion), elbow portion and wrist portion of the patient H are puncture sites.
[0032]
First, the openings 31a and 31b having the groin portion as the puncture site are opened at substantially the center of the base sheet 2, and the vicinity of the bases of both feet of the patient H is exposed, from which the femoral portion (femoral arteriovenous portion) The sheath and catheter can be inserted toward the head. In this example, the openings 31a and 31b are formed in an elliptical shape having a major axis of 120 mm and a minor axis of 100 mm.
[0033]
The openings 32a and 32b having the clavicle portion as the puncture site are opened on the upper side of the base sheet 2 to expose the neck of the patient H and the periphery of the clavicle and from there to the subclavian or cervical artery and vein. The sheath and catheter can be inserted. The openings 32a and 32b are provided at positions that can be used even when the neck of the patient H is used as the puncture site. In this example, the openings 32a and 32b are formed in an elliptical shape having a major axis of 60 mm and a minor axis of 40 mm.
[0034]
The openings 33a and 33b having the elbow portion as the puncture site are opened on the left and right sides of the base sheet 2 so as to expose the elbow portions of both arms of the patient H and from there toward the brachial portion (brachial artery and vein). The sheath and catheter can be inserted. In this example, the openings 33a and 33b are formed in an elliptical shape having a major axis of 90 mm and a minor axis of 60 mm.
[0035]
The opening portions 3 4 a and 34 b having the wrist portion as the puncture site are opened on the left and right sides of the base sheet 2 to expose the wrist portions of both arms of the patient H, and from there the radial portion (peristaltic vein) The sheath and catheter are inserted toward the head. In this example, the openings 34a and 34b are formed in an elliptical shape having a major axis of 90 mm and a minor axis of 60 mm.
[0036]
Among the eight openings 31a to 34a and 31b to 34b, the openings 33a to 34a and 33b to 34b corresponding to the elbow and wrist are hands provided on the work table 10 on which the patient H is placed. It is preferable to be provided at a predetermined angle along a table (in FIG. 1, widened in a letter C shape). According to this, since each opening part 33a-34a, 33b-34b is formed along a hand stand, it can operate without forcing the patient H to an unreasonable posture.
[0037]
The hand platform is movably provided on the work table 10 and is used to fix the arm of the patient H at an appropriate position. Usually, when using the openings 32a to 34a and 32b to 34b corresponding to the clavicle part, the elbow part, and the wrist part, the hand stand is widened so that the arm has a letter C shape as shown in FIG. When the openings 31a and 31b corresponding to are used, the table is moved so that the arms are parallel as shown in FIG.
[0038]
Each opening 3 is formed by a hole in which a part of the base sheet 2 is cut out in an elliptical shape. However, as shown in FIG. 3, the adhesive surface 26 surrounds each opening 3 on the back side of the base sheet 2. Is formed within a predetermined range. Further, a separator 4 for protecting the adhesive surface 26 is provided on the back surface side of the base sheet 2, and the unused opening 3 is closed by this separator 4.
[0039]
The adhesive surface 26 is also a fixing means for fixing the periphery of each opening 3 selected at the time of the treatment to the patient H, and therefore, an adhesive that is gentle to the human body, that is, is hypoallergenic is used. Is preferred.
[0040]
In this example, the separator 4 is made of a sheet piece made of the same material as that of the base sheet 2 and is formed in a size that can cover at least the adhesive surface 26. As a more preferable aspect of this separator 4, it is preferable that the surface on the opposite opening 3 side has liquid absorbability so that the unused opening 3 also has liquid absorbency at the time of treatment.
[0041]
By the way, when a catheter is inserted from the femoral part (femoral arteriovenous part) of the groin or when treatment is performed by a technique from the wrist or elbow, a large amount of bleeding is expected. Therefore, a high-absorbency sheet 5 having better liquid absorbency than the base sheet 2 is further provided around the openings 31 a and 32 b corresponding to the groin portion of the base sheet 2.
[0042]
The superabsorbent sheet 5 is made of a sheet piece containing or blended with a superabsorbent, such as an absorbent polymer, for example, and surrounds the openings 31a and 32b of the groin as shown in FIGS. It is formed in a rectangular shape.
[0043]
The superabsorbent sheet 5 is integrally formed at both ends of the fixing portion 51 and fixed to the base sheet 2 at the center portion thereof, and is not fixed to the base sheet 2. Parts 52 and 52.
[0044]
The fixing portion 51 is integrated with the base sheet 2 by heat sealing or adhesion, and openings 51a and 51b corresponding to the openings 31a and 32b of the base sheet 2 are integrally formed. Note that the fixing method of the fixing portion 51 is arbitrary.
[0045]
The unfixed portion 52 is not fixed to the base sheet 2 and can be bent via virtual fold lines 53 and 53. According to this, normally, when inserting a sheath and a catheter into the inguinal region, as shown in FIG. 6, both arms of the patient H are so-called straight along the body core by the hand platform of the work table 10. Arranged in a “careful” position. Note that the fold lines 53 and 53 may be provided with physical folds by perforations or the like. Moreover, when inserting a sheath and a catheter from a hand (an elbow part, a wrist part), the test | inspection and treatment in the said attitude | position can be used similarly.
[0046]
Therefore, an arm is arrange | positioned by the side of both legs, and the non-adhering part 52 of the superabsorbent sheet 5 is lifted by the swelling of the arm. Thereby, the non-adhered portions 52 and 52 build a weir, so that the blood flowing out from the openings 31 a and 31 b can be effectively damped and reliably absorbed by the highly absorbent sheet 5.
[0047]
The superabsorbent sheet 5 is not used exclusively for the drape 1 for angiographic examination, and can be applied to various surgical drapes.
[0048]
【The invention's effect】
As described above, according to the present invention, in angiography drape having an opening is formed for exposing the puncture site of angiography (angiographic) surgery to the base sheet at a predetermined position of the base sheet, By providing a hand-cuttable slit to expose the patient's face, it is possible to easily and safely expose the face in front of the patient's face without using scissors and remove the feeling of pressure. I can .
[0049]
In addition, since pockets are provided at both ends of the base sheet to accommodate blood that has bleed from the puncture site, blood can be prevented from dripping onto the floor, improving hygiene and safety. Can be planned.
[0050]
In addition, a superabsorbent sheet with better liquid absorbency than the base sheet is fixed around the opening of the groin, which is a puncture site with a large amount of bleeding in the base sheet. Since both ends of the sheet are lifted, blood that has bleed from the puncture site can be damped and reliably absorbed at both ends of the highly absorbent sheet. Each of these functions can improve work efficiency and reduce costs in the medical field.
