Description

201228630 VI. Description of the Invention: [Technical Field] The present invention relates to a treatment or examination using a vascular puncture such as injection oblique, which can be conveniently used after the removal of an injection needle or the like is used. A tourniquet that is bleeding and effective for use in the puncture site. [Prior Art] Self-study knows that for blood vessels such as veins or arteries, for the purpose of treatment, examination, prevention, blood donation, etc., blood vessels are puncture using an injection needle or the like to perform medical treatment. After this medical procedure, hemostasis after puncture must be taken. Conventionally, in order to perform such hemostasis, in the case of simple hemostasis, a surface such as a gauze piece, a formed piece of cotton, etc. is attached to the surface of a plastic adhesive tape or the like, and then the gauze piece and the formed cotton are attached. When the sheet is overlapped with the puncture position, the adhesive tape is attached for about 5 to 1 G minutes, or when the bleeding is severe: the situation is as follows: after the catheter is inserted into the artery, etc., the adhesive tape is used. Large pads are placed on top of each other and held for a few hours without moving. However, when the adhesive tape is used, it may cause an allergic-reaction due to personal differences, and a sticky adhesive is adhered to the skin, and the tape itself may cause irritation to the skin, which is not preferable. Also, if the method of sticking is not good, it can't just touch the puncture place, but if it is reattached, it will lose its effect. In actual use, almost all of the adhesive tapes are used by hand, so it is used. There is still room for improvement in terms of ease and effectiveness. 100143081 3 201228630 In order to be able to perform the hemostasis easily and reliably, the hemostatic device consisting of a pad with a puncture hole for the blood vessel and a pressure-sensitive double-sided adhesive tape is provided. 1). The pressure-sensitive double-sided adhesive tape is wound so as to maintain the position when the potential is pressed against the puncture hole, and the dragon is age-reducing or micro-axial, and the back of the body is strong. Sex. In particular, the hemostatic device uses pressure-sensitive double-sided adhesive tape instead of the adhesive tape. Although it does not have the same allergic problems as described above, it is excellent, although the pressing force and pressing force of the pad can be adjusted in the appropriate range. Internal, but because it is also related to the thickness of the mat, etc., it is generally difficult to perform. In Patent Document i, if the thickness of the pad is set to be in the range of 3 mm to 30 mm, the problem can be solved (paragraph 0013 of Patent Document 1). However, even if the design range of the thickness is set to a wide range, one hemostatic device has only one specific type. The thickness is not limited to the size of the part to be used by the user (especially the winding circumference of the use part), and the thickness cannot be changed in accordance with the normal machine strain. As a result, the appropriate pad pressing force and pressing force are difficult. It is realized by the relationship between the binding force of the pressure-sensitive double-sided adhesive tape. [Provisional Technical Documents] [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2002-95668 (Draft of the Invention) (Problems to be Solved by the Invention) 100143081 4 201228630 The present invention is directed to the above problems in view of the above problems. : When it is used to stop bleeding, it can easily obtain the appropriate hemostatic band of pressing force and pressing force according to the relationship between the binding force of the pressure-sensitive double-sided self-adhesive tape.

According to the ninth aspect of the invention, the tourniquet is characterized in that the sputum and the stretch-recoverable belt constitute mutually releasable and detachable members', thereby providing at least a common use of the stretch-recovering I1 belt and appropriately changing various sizes [area (vertical, horizontal), Height] 塾 use - the tourniquet. - [Embodiment] Hereinafter, the tourniquet of the present invention will be described in more detail. As shown in FIG. 1 to FIG. 3, the A blood band 1 of the present invention comprises: a hemostatic sputum composed of a cellulose sponge having a water swelling ratio of 110 to 1300%, and a belt having a stretch recovery property; the stretch recovery The sexual band has a sufficient length to wind a part of the body to at least exceed the ankle ring, and the length of the fracture in the longitudinal direction is 95% or more and 400% or less, and the length direction is 80%. The recovery rate after stretching is 6 % or more and 85% or less, and the recovery ratio after stretching in the longitudinal direction of 50% is 85% or more and 95% or less of the pressure-sensitive surface back self-adhesive stretch-recoverable non-woven fabric. The pressure-sensitive surface-back self-adhesive stretch-recoverable non-woven fabric used in the present invention has the same function as that of the pressure-sensitive double-sided adhesive tape used in the above-mentioned Patent Document 1. In particular, the adhesive body is not used even if an adhesive is not used. The finely crimped structure of the single fiber which is not woven by itself, and the function of the two (double-sided) mutually opposing engagement at the portion where the surface and the back surface of the nonwoven fabric are opposed to each other. In particular, when the stretch-recoverable non-woven fabric is pressed with a slight tension in the longitudinal direction, the fabric crimping structure on the square surface is more strongly entangled if the surface is overlapped with the back surface. A strong joint force is obtained. When the joint is to be subjected to a force to be torn by a human hand, the non-woven fabric can be easily separated without being particularly damaged, and the extension can be freely performed while the stretch-recoverable non-woven fabric maintains the form. Engagement and separation (loading and unloading). Such a mechanism of joining/separation is a finely crimped structure (fine ring structure) of the nonwoven fabric, which imparts stretch recovery to the nonwoven fabric, and the crimping structure near the surface and the crimping structure near the back surface are mutually The entanglement with each other results in interlacing and intertwining in a manner of mutual engagement, thereby imparting a mutual bonding force to the front surface and the back surface. On the other hand, even if the joint is to be released by applying a force to release the joint state (especially the parallel force of the surface that is stretched back to the non-woven fabric), the crimping structure will subtly expand and contract, which will promote the tightness. The tightly-engaged surface • the interlacing behavior of the single fibers on the back side, and bounces the force to be liberated parallel to the stretch-recovery non-woven fabric surface, while maintaining the engaged state, and maintaining the joint state of the surface and the back surface. On the other hand, if the tearing force is applied to the vertical direction of the surface which is stretched back to the non-woven fabric, the occlusal structure of the crimping structure is secreted from the side, in particular, the crimping of the single fibers with each other does not occur. Tightly engaging behavior, the two will be separated and liberated. The behavior/mechanism as described above can be interpreted as being arranged in parallel with two snails having a roughly (four) same helical diameter and spacing, and in the case of stretching the spiral 100143081 „ 201228630 interlacing/engaging, using The same kind is produced when the two are to be overlapped. Therefore, the extension is restored to the back of the non-woven fabric on the back of the watch, when the object is rubbed and joined, especially in the special degree of stretching force (ie, the above Z is called "spiral", and in the case of "contracted ring structure", when it is rolled and joined, it exhibits a higher effect of binding force. The reason is that in this situation, the force to be liberated (the force to be unwrapped) acts as a parallel force in the direction of the extension to return the non-woven fabric, and the extension returns to the non-woven fabric, and the A-frame resists the force. Moreover, the force against the peeling force from the vertical direction of the non-woven fabric is weak, so that it can be peeled off relatively simply. According to the present invention, the self-binding force of the stretch recovery belt composed of the self-adhesive stretch non-woven fabric of the pressure sensitive surface f-shaped surface is pressed against the puncture site and stopped. The focus of the hemostatic pad is that the water swelling ratio is 110 to 1300%, and it is preferably composed of a cellulose sponge having a thickness of about 0.5 mm to 30 mm when dry. If the two ranges are met, the thickness will increase to some extent due to inhalation of blood, and the volume will increase due to shame, which will become the cause of achieving appropriate pressure. If the hemostatic pad is to exert this effect better, the water swelling rate is preferably 300 800 / 〇, and when used, the thickness is better when the drying is 〇岔 melon ~ 2 〇 mm, the best is 1 mm ~ l 〇 mm range Inside. The water swelling ratio of the hemostatic pad can be adjusted by appropriately adjusting the compression molding ratio at the time of hot pressing when the cellulosic sponge is shaped into a blood pad. By adjusting the compression molding ratio of 100143081 9 201228630 by hot pressing, it can be manufactured by itself. Such as _ whole hemostasis thickness and water absorption rate and pressure-sensitive surface self-adhesive stretch recovery non-woven fabric in order to be able to press the pressure on the hemostatic part 'focus on having at least a part of the body part of the work circle' that is not woven At both ends in the longitudinal direction, the surface and the back surface thereof can be wound to a sufficient length to be wound. The reason is that the stretch-return non-woven fabric does not have a special joining force to the skin, but the back surface of the front and back sides of the non-woven fabric are overlapped and opposed to each other. According to the findings of the inventors of the present invention, it is sufficient to increase the length of i to about 60% in addition to the i-ring portion. However, the difference between the individual and the part to be used is different. As long as the product is about 30 cm to 100 cm in length, it is a good product that can cope with various situations. The key point of the self-adhesive stretch-recoverable non-woven fabric on the back side of the pressure-sensitive surface is that the length-direction fracture elongation is 95% or more and 4_ or less, and the recovery rate after the length direction is 6G% or more and 85% or less, and the length direction is 鄕The recovery rate after stretching is 85% or more and 95% or less. That is to say, the focus of the stretch recovery performance of the 4 woven fabric is: the degree of fracture elongation without damage to the damage in the normal use state when the enterprise is stopped, for example, when the long fracture extension is such as an excessive situation such as war, It is quite difficult to obtain a stable and high table f-engaging force (even a high pressing force on the hemostatic portion), which is not preferable. When the elongation at break in the length direction is less than 95%, even if the micro-stretching is called, there will be many places where the self-stretching recovery performance of the non-woven fabric does not return to the original state, and the entire back surface of the watch is obtained. The joining force and the binding force are easily lowered, and it is difficult to obtain the effects of the present invention. That is, the deformation of the non-woven fabric self-propagating from the structural surface is caused by the deformation of the structure surface, which may result in the fact that at least the binding force generated by the whole portion cannot be supported, so that the overall binding force cannot be obtained. In particular, the stretch recovery performance of the non-woven fabric is partially damaged, and most of them occur at important positions where the binding force is present. Therefore, under the premise of normal use, the stretch-delay value of the stretch-recoverable non-woven fabric does not occur, It is important to set the recovery rate value after stretching in the longitudinal direction of 80% and the recovery rate value after stretching in the longitudinal direction. When the recovery rate after 80% elongation in the longitudinal direction is smaller than 6〇%, the stretch recovery stress of the stretch recovery property is lowered. Therefore, the hemostasis pressure caused by the tensile stress of the non-woven fabric is lowered, so that the original purpose (hemostasis) cannot be achieved. The reason is that if the stretch of the non-woven fabric is too large, the interwoven structure between the fibers in the non-woven fabric will begin to be damaged, and the stress transfer between the fibers will be impaired. If this state is reached, for example, even if the non-woven fabric tape can be stretched, the stretch recovery rate and the restoring force of the tape obtained at this time become small, and the hemostasis pressure becomes small, which is not preferable. When the recovery rate after stretching in the longitudinal direction of 80% is 85%, the binding force obtained by stretching the nonwoven fabric band becomes too large, and the hemostasis pressure becomes excessively large, which is not preferable. Furthermore, the recovery rate after stretching at 50% in the longitudinal direction is less than 85°/. When the binding force is small, it is not preferable. In addition, when the recovery rate after the length direction 50% stretch 100143081 11 201228630 is larger than 9 5 %, the binding force obtained by stretching the money of the helmet and the 铋 ^ 曰 曰 曰 曰 曰 曰 曰 曰 ' ' ' ' ' ' ' ' ' More than the above, it is not preferred. The present invention consists of a stretch-recovery belt consisting of stretch-recoverable non-woven fabrics, with a focus on moderate (four) exhibiting recovery characteristics, and if overstretched, the structure is destroyed and the reply (four) traits cannot be exerted. More preferably, the elongation at break is 100% or more and 3% or less in the longitudinal direction. _ The recovery after stretching is 鸠 or more and the length in the longitudinal direction is 5〇%. The recovery after stretching is 90% or more and 95% or less. In addition, the above-mentioned moderate stretch recovery characteristics and the characteristics that the structure is broken and the resilience cannot be restored when the structure is excessively stretched can be more evenly and well-developed, and the user becomes more likely to feel the shape (the length direction is 5). The ratio of the value of the recovery rate after 〇/〇 stretching/(the recovery rate after stretching in the longitudinal direction of 8〇%) is preferably 1.1 or more and 14 or less, more preferably hl or more and u or less. The tourniquet of the present invention having the above characteristics is generally used in accordance with the elongation in the range of about 2% to about 1%, and the relationship between the extension of the stretching and non-woven fabric and the binding force is generally good. It exhibits a binding force, and it is suitable and preferable in terms of obtaining a suitable pressing effect and a higher hemostatic effect. In other words, in the case where the tourniquet of the present invention is used in the range of 20% to 100% in the longitudinal direction, the thickness of the pad can be automatically obtained to obtain an appropriate pressing effect. 100143081 12 201228630 The elongation in the longitudinal direction is in the range of 20% to 100%, and the stretch-recoverable non-woven fabric having the above characteristics in the present invention means that the stretching behavior is mainly caused by elastic deformation, and does not mean It mainly produces stretches until "plastic deformation". As a result, the present invention can be interpreted as a state of stretching deformation mainly causing elastic deformation, and in a deformation region which is stretched and deformed in a state in which "plastic deformation" occurs slightly or not, the user is wound while stretching, and the system is adapted. It is the most important thing in terms of pressure. Here, "the elongation in the longitudinal direction is 20%" means that, for example, when the length is 2 mm, when used in a state of stretching to 240 mm, the elongation in the longitudinal direction is 20%. Therefore, in the use of the tourniquet of the present invention, it is preferred to follow the above-described stretch ratio of 20% to 100 Å/〇, such that the ends of one of the bands are stretched and overlapped and pre-colored or marked at their position. However, even if there is no such coloring and marking 4, it is possible to easily obtain the desired effect by using the hand/finger to feel whether the stretching is an extension within the elastic deformation in accordance with the usage habit. The length of the tourniquet is preferably about 1.1 to 1.6 times the length of the body portion to be wound, but it may have a length longer than the shorter one. Generally, when it is wound around the wrist, it is preferably set in the range of about 3 〇 cm to 40 cm, and more preferably, the length is appropriately sufficient, and it is assumed that the winding is such as the foot, the head, the abdomen, and the like. Preferably, it is set in the range of about 5 〇cm~12 〇cm. The pressure-sensitive surface back self-adhesive stretch-recoverable non-woven fabric used in the present invention is 100143081 13 201228630. According to the finely crimped structure of each single fiber constituting the structure, the woven fabric, the quarantine, or the quilt is used. Stepwise (4) treatment or water column punching (water jet punching interlacing), or high-speed vapor flow and other interlacing treatment, while maintaining the form of non-woven fabric, if used according to the above range _ stretch rate, the extension of the length direction and the shrinkage of the 忒 stretch amount Reversible. In particular, if the water column is punched (water-hole interlaced), or sprayed with low-pressure water, or interlaced by spraying, it is continuously carried out along the length direction of the nonwoven fabric, and the phase is 35Q 8 to 5 mm in the width direction. The interval is intermittently performed, and the portion in which the constituent fibers are present at a high density and the portion at a low density are formed in a "money (φ) state" in the non-woven fabric length direction. On the other hand, if the tourniquet is formed in the longitudinal direction of the nonwoven fabric (the hard direction of the field) and the length of the tourniquet, the longitudinal extension and recovery characteristics of the tourniquet are more excellent (the stretch recovery is reversible and rich) Repeated repeat durability). A basic construction and manufacturing method of such a pressure-sensitive surface back self-adhesive stretch-recoverable nonwoven fabric is known, for example, from International Publication No. 2/8/15,972. That is, the non-woven fabric known from the international publication WO 2008/015972 contains a composite fiber having a phase structure formed by a plurality of resins having different heat shrinkage ratios (or thermal expansion rates). The composite fiber is mainly oriented in the plane direction along the alignment axis. It has a coil shape with a mean radius of curvature of 20 to 200 μm. The non-woven fabric is such that high temperature (overheating belongs to heating) water vapor acts on the mesh containing the composite fiber, so that the composite fiber exhibits curling, and the fibers are not melted with each other. 100143081 201228630

It can be obtained by performing (mechanical) tangling under the condition of It. The composite fiber used is a fiber which is asymmetrical or layered (so-called bimetallic) structure which is caused by a difference in heat shrinkage (or coefficient of thermal expansion) due to a plurality of resins due to heating (potential crimping) fiber). The lions usually have different recording points or melting points, such as polyolefin resin, acrylic resin, polyvinyl acetal resin, polyvinyl chloride resin, polyvinylidene gas-based resin, and styrene. Resin, polyester resin (poly-p-butyl phthalate resin, poly-p-benzoic acid propylene resin), poly-p-dibenzoic acid butyl acrylate resin, polyethylene naphthalate resin Etc., polyamine-based resin (polyamide 6, polyamide 66, polyamide 11, polyamide 12, polyamine 61 〇, polyamide 612 and other aliphatic polyamine resins; semi-aromatic A polyammonium resin, polyphenylene isophthalamide, polyhexamethylene terephthalamide, polyparaphenylene terephthalamide, and other aromatic polyamines Resin or the like); polycarbonate resin (such as bisphenol A type polycarbonate), polyparaphenylene benzobisoxazole resin, polyphenylene sulfide resin, polyurethane resin, cellulose resin It is selected among thermoplastic resins such as cellulose esters. In the above, the present invention is preferably a non-wet, heat-adhesive resin having a softening point or a melting point of 100 C or more, from the viewpoint of being melted or softened by heat treatment using high-temperature steam. Or a heat-resistant hydrophobic resin or a non-aqueous resin, for example, a polypropylene-based resin, a polyester-based resin, or a polyamid-based resin, and it is preferable to use aromatics in particular from the viewpoint of excellent balance between heat resistance and fiber formability. A polyester resin or a polyamide resin. Composition 100143081 15 201228630 Port: The plural resin of Dai: 隹 can be a combination of the same system resin as long as the heat shrinkage rate is different ‘may be a combination of different types of resins. Further, in particular, it is possible to form a longitudinal elongation at break of 95% or more and 4% or less, and a recovery ratio of 60% or more and 85 〇/° or less after stretching in the longitudinal direction. The response rate is 85% or more and 95% or less of the pressure-sensitive surface back © from (4) stretching and returning non-woven fabric, adjusting the surface density (g/m2) of the non-woven fabric on the rib, and appropriately performing the interlacer according to the aforementioned method. . The surface density of the non-woven fabric is preferably produced in the range of 50 g/m 2 to 2 〇〇 g/m 2 , and the mesh adjusted to the range is subjected to a required water recovery amount and water pressure in accordance with the required stretch recovery ratio. Moderate interleaving. Although it is difficult to generalize the conditions according to the surface density of the net, etc., when spraying or water spray treatment, it is preferably carried out according to the range of O.^^MPa. If the surface density of the mesh is too low, the interwoven fibers will be too small, resulting in failure to obtain the desired stretch recovery. Further, if the surface density of the net is too high, it is easier to obtain the desired stretch recovery rate', but the texture of the non-woven fabric becomes hard, and it is not applicable to the blood strip. Specifically, there is a problem that the elastic modulus at the time of stretching is too large, resulting in difficulty in stretching, and excessive fastening force after being wound around the body. Furthermore, the recovery rate after stretching in a range of 1% or more and 300% or less and 8 % in the longitudinal direction in a better range is 7% or more and 85% or less, and 50% after stretching in the longitudinal direction. The recovery rate is above 9〇% and below 95%. It is generally best to design the surface density of the mesh within the range of GOqSOg/ni2, 100143081

S 16 201228630 More preferably, the H65g/m2 range can be manufactured by setting the treatment water flow pressure to a range of 0.5 8' OMPa β, and performing separate processing from a few stages to several stages. If the pressure of the treated water is too high, a higher stretch recovery rate is not secret. In order to make the single fiber constituting the non-woven fabric exhibit fine crimping, it is possible to achieve a special three-dimensional crimping by forming a fiber-based composite fiber, so that a so-called double-gold-light composite is formed. . Fibers are present on the surface of the nonwoven fabric. (4) It is better to use the interwoven structure. (4) It is preferable to use short fibers, and the short fibers of about 35 to 75 legs are used.宗 In the case of manufacturing the pressure-sensitive surface of the present invention, the self-adhesive stretched nonwoven fabric is first obtained by a plurality of resins having different heat shrinkage ratios (or thermal expansion rates) to form a bimetallic structure. The mesh formed by the mouth-like dimension, and then the high-temperature heat is overheated or heated.) The steam is used to contain the composite fiber, and the fiber is crimped, and the fibers are bonded to each other. In order to obtain a non-woven fabric composed of the constituent fibers which are mainly oriented in the plane direction and have a coil-like average along the alignment axis. Special:: The heat treatment of the wide water vapor can be evenly processed at high temperature (overheating or heating) π 吟t σ % to the inside of the non-woven fabric, which can be more efficient and the mesh in front of the coil is easier. It is better to obtain the target (4). Further, the heat treatment is introduced into the heat treatment machine. k stretchability, stretch recovery, preferably super 100143081 17 201228630 The above-mentioned three-dimensional crimp produced by this is preferably a coil-like crimp (curl) having an average diameter of 45 to ΙΙΟμιη. Further, the number of surface curls is 30 to 150/mm2, and if this range is satisfied, the balance of self-adhesiveness, repeated pressure resistance, pressure resistance after 10 minutes, air permeability, and moisture permeability can be obtained. Excellent. Further, in the case of producing a non-woven fabric having a coil-like crimp (crimped) average diameter of 45 to 11 μm and a surface crimp number of 30 to 150/mm 2 , for example, a composite fiber of the above various configurations is used, by using the composite fiber. The compounding ratio of the high shrinkage resin component and the low shrinkage resin component can be achieved by a ratio of two components of the high shrinkage resin component/low shrinkage resin component of 30/70 to 70/30. In particular, it is more preferable to use the ratio of 45 to 55/55 to 45, and the best system is 50/50. More specifically, the fibers are used to form a web having a predetermined surface density, and the web can be manufactured by performing steps such as preliminary interweaving, overfeeding, high-speed steam treatment, drying, etc., by the processes. When the conditions are equalized, the number of surface curls and the curl diameter of the coil-like crimp can be adjusted. If the surface density is increased, the degree of pre-interlacing is lowered, or the steam treatment or drying is enhanced, the curl diameter is reduced and the number of crimps tends to increase, and the combination of these conditions can be used to adjust the value. . Further, the fiber structure of the heat-treated crimped fiber is preferably about ιμηη to 30 μιη, more preferably about 12 μm to 18 μιη. An appropriate balance can be obtained between the fiber diameter, the crimp diameter, and the number of crimps. In particular, if the fiber diameter is coarse and the crimp diameter is small, it is not easy to bite into the curl of other fibers between the curls between the fibers, and even if there is biting, the bite depth 100143081 18 201228630 will become shallow, and the result will be self-adhesive. The tendency to reduce sexuality. Therefore, it is important to pay attention to this relationship and perform the above processing in a balanced manner. The average fineness of the composite fiber constituting the stretch-recoverable non-woven fabric is preferably 1 to 5 dtex, more preferably 5 to 3 dtex. If the fineness is too fine, the fiber itself is difficult to manufacture, and it is difficult to ensure fiber strength, so it is preferable to avoid In the step of presenting the crimping, it is more difficult to make a beautiful coil-like crimp. On the other hand, if the fineness is too large, the fiber becomes straight, and even if it is curled, the texture of the non-woven fabric is rough, which impairs the touch when it comes into contact with the skin, and thus the blood band is not applied. The number of crimps (mechanical crimping number) of the nonwoven fabric before the heat treatment (before the crimping treatment) is preferably 25 pieces/25 nmi, more preferably 5 to 20 pieces/25 mm per unit length. The number of crimps after the heat treatment is preferably 35 to 15 / / 25 mm, more preferably 40 to 120 / 25 mm, and particularly preferably 50 to 1 / 25 mm. The stretch-recoverable nonwoven fabric of the present invention thus produced preferably has a gas permeability of 50 to 450 cm 3 /cm 2 /sec and a moisture permeability of 430 to 750 g/m 2 /hr. The air permeability and moisture permeability are obtained by adjusting, for example, the surface density of the nonwoven fabric, the average fineness of the constituent composite fibers, the fiber interlacing treatment condition at the time of nonwoven fabric production, the processing conditions for crimping, and the like. The combination has such air permeability and moisture permeability, and when the tourniquet is used in the case of hemostasis in a state in which the tourniquet is overlapped and wound, it is preferable because it does not become stuffy even if it is sweaty. The tourniquet portion (non-woven portion) of the present invention is excellent in quick-drying property because it constitutes a fiber 100143081 19 201228630, and it hardly absorbs sweat, and does not sustain the problem for a long period of time. And if there is such as ± material position, migrating wet state. In other words, the tourniquet is not related to this matter, and the components other than the present invention are made of, for example, an elastic (four) film material or the like due to the elasticity of importance, or the adhesive is applied to the surface of the tape. The coating material of the material, etc., is a poorly ventilated one and has poor moisture permeability. Therefore, there is usually a feeling of sweltering in use, which is poor in use. In addition, the air permeability and moisture permeability of the sealing tape of the present invention are preferred. In the above range, 'better air permeability system, (10) to 45 〇 cmW/sec, and particularly good system is 120 to 45 〇 cm 3 /cm 2 / sec. If the air permeability is too low, the comfort at the time of use will be impaired. Conversely, if it consists of a thinner material that is too ventilated, the physical properties of the belt will decrease, making it difficult to have the force required for the stagnation. The relevant moisture permeability is also better within the above range, and better. 5(K)~75Qg/m2/hp is better than 550~, g/m2/hr. When it deviates from the upper limit and the lower limit, it is not the balance between the above-mentioned sultry feeling and physical properties. The tourniquet of the present invention is shown in the schematic diagram of Figures 1 to 3, in the pressure sensitive The surface is self-adhesive and stretched back to the appropriate position on the non-woven fabric 2, and the hemostatic pad 3 is set according to the fixed cancer or the temporary m-fixed state, and the blood band 1 is stretched while the Wei is connected to the hemostasis position. The position at which the body is wound (wrist or the like) is one or more times, and the front end portion of the non-woven fabric 2 on the winding side is not overlapped by the arrow in the figure J, and the non-woven fabric is superposed on the opposite side while maintaining the above-mentioned extended state. 2 100143081 20 201228630钿 卩. 卩 near or has been wound around the non-woven part 'and use the overlap and the binding force' to press against the blood pad. The binding force is not only produced at the overlapping part The hemostatic system is as described above, and the emphasis is on the water swelling ratio of 110 to 1300%. It is preferably used when the thickness is 1 mm to 10 mm when dry, and the water swelling rate is 300 800 /. When the blood volume is high, the pad is used. The body will absorb the blood and swell more, and push the pressure upwards. If it is kept in this state for 5 minutes to 1G minutes, the blood can be stopped by puncture the vein by a general injection needle. The thickness of the hemostatic pad is preferably 5mm when using water. Within 10〇mm However, when blood is collected at a place such as a wrist, it is also possible to use a few mm to about 10 mm. Here, cellulose sponge is generally known to be: cellulose (cellulose) derived from paper, and It is a high-performance function composed of natural fibers such as flax, cotton, etc., which are appropriately added as reinforcing fibers. The lysin sponge has a substance consisting essentially of natural materials, and because cellulose has a hydrophilic group (〇H group). Therefore, it is easier to chemically infiltrate moisture, and it has excellent water absorption capacity and softness. As described so far, the tourniquet of the present invention has a moderate fracture elongation and a post-employment recovery rate (four) (Laibu), From the combination of the water absorption of the material and the swelling of the pad, the pressure for the hemostatic material can be increased. The force of the pressing is when the belt is pressed against the raft (not woven),

The stretch rate is 20%~100%. The state of pressing the pad is eight and D is rewinding, and in the middle state, the faces that overlap each other are joined together, and the tape is pressed 100143081 21 201228630 The slipping ' acts as a force against the skin side from the surface direction of the belt, and becomes a pressure against the hemostatic portion. The "joining" between the above surfaces is not formed by using an adhesive or the like, but is referred to as "engagement" between the faces. In particular, when a part of the mat is combined with an artistic shape or a property which is swollen by liquid absorption, it can be partially pressed with a relatively high pressure. Because it is used to stop bleeding in this state, it can improve the effect of blood. It is important to maintain this state during the period of hemostasis, during which time the average factor is minutes to 1G minutes. In Guan _, it is important to maintain a certain I resistance to the hemostasis department. That is, in the hemostasis, there may be movements of the body, which may cause the muscles to move and swell or become thinner due to the movement of the ash belt, such as a wrist, a leg, or other parts of the body, thereby causing the belt to be oriented in the longitudinal direction. The telescopic action 'either fine at the beginning is dry (4), but the body (4) is aspirate and the heart is X. At the beginning of the hemostasis, the amount of blood and the like is also large, and the best resistance is also U. It is important to be able to appropriately respond to such various conditions and changes in the combination of the non-woven fabric and the water-swelling ratio. In the above-described method, the pressure-reducing force of the crotch portion of the present invention is preferably in the dry and wet state without a dry state, and is preferably 5 () to less than 6.0 to 20 N. If the pressing force is less than the pass, there is a case where the soil cannot be stopped reliably. Moreover, if it is larger than 20 inches, although it can be stopped, it may be painful because of tightness or tightness, or it may be the cause of the situation in the front part of the hemostatic site. Full; I above the scope of the matter, on the hemostasis function, and the use of the first 100143081 22 201228630 suitability and other points of view are important. The prior art is not perfect for this, etc. As described above, the mat may be fixed to a specific position on the stretch recovery belt, or the mat and the stretch recovery belt may constitute an individual that is removably attachable to each other. When the two are composed of individuals, on the side of the side of the tourniquet, in order to temporarily engage the stretch-recoverable non-woven fabric, the self-adhesive stretch back of the pressure-sensitive surface of the stretch-reducing belt can be attached and attached. Non-woven fabric is the same. Further, an adhesive component such as a micro-adhesive may be subjected to a treatment of a part or the whole of the surface to form a temporarily fixable state. According to this configuration, the pad can be placed in a temporarily fixed state at any desired position such as the center position of the tourniquet, and the workability when the tourniquet is wound with the pad can be improved. Moreover, it is convenient in this point that the tourniquet has not been damaged and its stretch recovery characteristics are used, and it is only necessary to replace the pad for repeated use. [Examples] Hereinafter, specific configurations and effects of the tourniquet of the present invention will be described using examples. Further, in the present invention, the surface density, the thickness, the density, the longitudinal direction breaking strength, the elongation, the recovery rate after stretching in the longitudinal direction of 80%, the recovery rate after stretching in the longitudinal direction of 50%, and self-adhesiveness, The measurement or evaluation was performed as follows.

MD direction) as the length direction, and cut the width by 3 (10) , test length l 〇 cm (distance between clamps). The sample was attached to a tensile tester, and tensile elongation was carried out at a speed of 2%/min of the length of the test. When the maximum strength of the strain-intensity curve at this time is set to break, it is regarded as the fracture MD strength value and the MD direction fracture ductility of the sample. Further, when a plurality of sharp bee values have occurred as of the maximum strength, the highest value of the strongest value is regarded as the cut-off portion, and the above value is obtained. The evaluation was carried out in accordance with the number of η = 3, and the average value of these was regarded as the breaking strength value and the fracture elongation in the Md direction (longitudinal direction) of the sample.

This sample was attached to a tensile tester, and the tensile strain was set to 200%/min of the test length, and the tensile strain (8 cm) at a test length of 8〇% was applied, and the strain was immediately removed at the same speed. At this time, the strain (Rsocm)' at which the tensile force became "0" was measured, and the recovery ratio after stretching in the longitudinal direction of 8〇% was calculated according to the following formula. Recovery rate after 80% stretch (%) = {(1 〇 _r8()) / 1 〇} X i 00 In addition, the measurement system sets the number of η to 3, and finds the ith position below the decimal point. Take the average and round to form an integer value. (b) Recovery rate after 50% extension in the longitudinal direction: According to the same method as the recovery rate after stretching in the longitudinal direction of 80%, the applied strain rate is 50% (extension strain (5 cm)), and the value is obtained. (r5()), the same recovery rate after 50% extension in the longitudinal direction is obtained according to the following formula. Recovery rate after 50% stretch (%) = {(10_υ/10} χΐ〇〇 (6) Number of surface curls: The number of curls was measured using a scanning microscope (type S3400N) manufactured by Hitachi High-Technologies Co., Ltd. The SEM photograph was taken at a magnification of 200 times, and the photograph was used for the observation range of 629·5 μmχιχ432 μπι for each photograph.

(14) Stress at the time of pressing: The stress at the time of pressing is evaluated when the affected part is wound using the hemostatic pad of the present invention, and when The hemostatic portion was measured by a model test by the pressing force generated by the combined structure of the pad and the stretch recovery belt, and evaluated. At this time, the shape of the mat 4 was evaluated for both the case of drying and the case of wetness. In the eight-system, the maximum stress value in the operation was measured by repeating the press-fitting action meter three times using the tester shown in Fig. 5. . The non-woven fabric 20 is prepared by setting the longitudinal direction of the original material (the flow direction in the manufacturing direction. MD direction) as the longitudinal direction, and cutting the width by 3 cm and the length of 30 cm (the distance between the clamps). The type of material non-woven fabric 20 is fixed at 33% according to the initial stretch ratio, and the two ends are fixedly fixed to the fixing jig 8. At this time, two fulcrums 7 are provided at the lower portion, and the fulcrum pitch 100143081 29 201228630 is set to be (span) 60 mm. The initial setting state of the sample non-woven fabric 20 is horizontal between the two fulcrums 7. The length of the sample non-woven fabric between the fulcrum 7 and the fixing jig 8 was set to 50 mm on each side. Therefore, the total length of the sample non-woven fabric 20 between the two end fixing jigs 8 is 160 mm. As shown in Fig. 5 (a) and (b), at the center position between the lower fulcrums 7 of the sample non-woven fabric 20, another fulcrum connected to the dynamometer moving downward from the top for measuring the pressing force is provided. (corresponding to the hemostatic point) 9, moving from the top toward the bottom 'and pressing against the portion of the pad 3. The lowering speed (pressing speed) of the fulcrum 9 was set to 100 mm/min. The distance to be pressed (the length of the descending stroke) is set to be 4 cm from the position with the straight line connected between the two lower fulcrums 7 as the reference position. In the measurement, the pad 3 is placed on the tape (sample non-woven fabric 20), and the stress generated at the fulcrum portion 9 when the above-described pressing operation is performed is performed. The pad 3 was evaluated for both the case of drying and the case of wetness, and when the wet state was set, 6 cc of distilled water was applied to the pad by a dropper. (15) Maintenance performance of the pressing force: The maximum stress value and the stress value after 10 minutes. Perform the same measurement

With the apparatus and the measuring method described in the above (14), the fulcrum 9 from the upper side is stopped at the lowest position when the first pressing operation has not been repeated three times: lower, 4 calls 'and maintains this state for 10 * clock The stress change generated by the fulcrum at this time was measured and evaluated. Observation of the pressing operation just after completion 100143081 201228630 [Example 1] The bimetallic structure of the composite fiber system uses a polyethylene terephthalate resin having an intrinsic viscosity of 0.65, and 20 mol% and 2% of isophthalic acid. Composite fiber composed of modified polyethylene terephthalate resin copolymerized with ethylene glycol 5 mol% ("KNRAY Co., Ltd.", "pN78", fineness 1.7 dtexx fiber length 51 mm, mechanical crimp A number of 12 still legs) short fibers were formed, and a web having a surface density of 52 g/m 2 composed of 1% by weight of the fibers was formed. The mesh was conveyed on a conveyance net so that the water was sprayed from the inside of the roll to the net at a pressure of 0.8 MPa between the multi-plate rolls which were formed in a staggered manner to micro-interlace the mesh fibers. The treated micro-interlaced and the super-extinguishing rate of 2% are transferred to a belt conveyor with a 3 inch mesh and a width leaking resin-made endless belt. The same belt is installed on the belt upper belt of the belt conveyor, and is rotated in the same direction at the same speed, and can be exchanged by a belt type of two (four) separators of any age. A:: The water vapor injection device installed in the belt type wheeling machine is introduced into the micro-interlacing net, and the device is ejected to the micro-interlaced net. .4Mpa water vapor and water black gas treatment 'Getting you'# A non-woven fabric in which the set fibers are crimped and the fibers are interwoven. Spot 'surface' 122g/m2 ° This non-woven fabric is the md direction /, . They are all well-stretched, and after the screen is stretched by the hand without breaking, the stress is relieved to cut the county. U-stretching 100143081 31 201228630 The non-woven fabric is self-adhesive and stretched back to the non-woven fabric. The recovery rate after 80% elongation in the length direction is 79%, and the recovery rate is 90% after stretching in the length direction of 5〇%. Also, density, fracture elongation, etc. are shown in Table 。. Further, the non-woven fabric was narrowed in the longitudinal direction of the nonwoven fabric by a width of 5 cm and wound into a roll shape to obtain the stretch-recovering self-adhesive tape of the present invention. Furthermore, the non-woven fabric was narrowed to a width of 3 cm x a length of 35 cm, and a longitudinal length of 25.1 mm, a width of 25.2 mm, a thickness of 114 mm when dried before use, and a water swelling rate of 790% were used as a hemostatic sputum, and an adhesive was used. A tourniquet was prepared by mounting on the stretched non-woven fabric, and evaluation was performed. The repeated pressing force was 10.5 N when dry 塾, and 15.5 N when 塾 was in a water absorbing state. Further, when the pressing force after 10 minutes was the drying pad, the initial maximum force was 14.3 N, and it was 9.6 N after 1 minute. When the water is absorbed, the initial strength is 15.2N, and after 10 minutes, it is 1〇·3Ν. As a result, it is possible to use the hemostatic pad which is naturally suitable in the state of the force and the pressing force without being too strong or too weak, and to form a tourniquet which is easy to use, and obtain a high evaluation. [Example 2] A non-woven fabric was obtained in the same manner as in Example i except that the surface density of the card web was set to 39 g/m in accordance with the conditions of the embodiment. The obtained nonwoven fabric was subjected to a surface density of 92 g/m2. The non-woven fabric is well stretched in the MD direction and is gently retracted by the hand without breaking. 100143081 201228630 After the stress is released, the original shape is immediately restored. 3 Hai non-woven fabric pressure-sensitive surface back self-adhesive stretched back non-woven fabric, the recovery rate after 80% stretch in the length direction is 72%, and the recovery rate after stretching in the length direction of 5〇% is 94%. Further, the density, the elongation at break, and the like are as shown in Table i. The non-woven fabric was narrowed to a length of 5 cm in the longitudinal direction of the nonwoven fabric and wound into a roll shape to obtain the stretch-recovering self-adhesive tape of the present invention. Furthermore, the non-woven fabric is narrowed to a width of 3 () 111) < 35 cm long, and has a length of 25.0 mm, a width of 25.2 mm, a thickness of 1 〇 1 _, and a water swelling rate of 339% when used before drying. To stop bleeding, make a tourniquet with an adhesive, and perform evaluation. The repeated pressing force was 9.9 N when the drying pad was used, and 10.0 N when the pad was in a water-absorbing state. Further, when the pressing force after 10 minutes was the drying pad, the initial maximum force was 8.2 N, and after 10 minutes, it was 6.0 N. When the water-absorbent pad was used, the initial maximum force was 11.ON, which was 6.9 N after 10 minutes. As a result, it is possible to use it in a state in which the naturally-adapted hemostatic pad is pressed under pressure and pressure without forming it too strong or too weak, and a tourniquet which is easy to use is formed, and a high evaluation is obtained. The hemostatic performance is somewhat inferior to that of Example 1 due to the reduced volume of the hemostatic pad. [Example 3] The same procedure as in Example 1 except that the composite short fiber used in Example 1 was set to 1% by mass, and a card having a surface degree of 60 g/m was formed by a carding method. The same is obtained without weaving. 100143081 33 201228630 The non-woven fabric obtained has a surface density of 141 g/m2. The non-woven fabric is well stretched in both the MD direction and the CD direction, and is gently stretched by the hand without breaking, and immediately returns to its original shape upon release of the stress. The non-woven fabric pressure-sensitive surface back self-adhesive stretched back non-woven fabric, and the recovery rate after stretching in the length direction of 80% was 84%, and the recovery rate after stretching in the longitudinal direction of 5〇% was 94%. Also, density, fracture elongation, etc. are shown in Table 。. The non-woven fabric was narrowed to a length of 5 cm in the longitudinal direction of the nonwoven fabric and wound into a roll shape to obtain the stretch-recovering self-adhesive tape of the present invention. Furthermore, the non-woven fabric was reduced to a width of 3 cm x a length of 35 cm, and a cellulose sponge of a thickness of 25.1 mm, a lateral direction of 25.1 mm, a thickness of 1 〇 3 mm before drying, and a water swelling rate of 790% was used as a hemostatic sputum. A tourniquet was made and evaluated. As a result, although it is not too strong or too weak, it can be used under the pressure/pressure state in a naturally suitable hemostatic sputum, but compared with the embodiment i and the same embodiment 2 , under pressure, slightly. [Example 4] Using a composite short fiber used in Example 1, 1% by mass, a card web having a surface density of about 4 〇g/m2 was formed by a carding method. The net is transported to the transporting network. After the preparatory water treatment is applied to the net, the porous plate drum with the fine holes is 'flowed from the net surface to the drum and flows toward the drum according to the columnar water flow of 25Mpa'. After being transported to 76 _ mesh (4) (4), the columnar water flow treatment of 3. 〇 MPa is carried out, and the mosquito __ is interwoven. 100143081 34 201228630 This treatment web was subjected to steam treatment in the same manner as in Example 1 to obtain a nonwoven fabric in which the composite fibers were crimped and the fibers were interlaced. At this time, the overfeed rate of the light interwoven net was 190%. The surface density of the non-woven fabric U6g/m is obtained. The flow of the non-woven fabric product is good in the direction of movement (MD) and width), and the stress is released by the hand without stretching. Immediately return to the original shape. The non-woven fabric is self-adhesive and stretched back to the non-woven fabric, and the recovery rate after the lengthwise extension is 72%, and the recovery rate after the length of 5〇% is 95%. Further, the density, the elongation of the fracture, and the like are shown in Table 1. The cotton cloth width 5em is reduced toward the length of the nonwoven fabric and wound into a roll shape to obtain the stretch recovery self-adhesive tape of the present invention. Furthermore, the non-woven fabric was narrowed to a width of 3 mm and a length of 35 cm, and a cellulose sponge pad having a thickness of 25.1 mm, a width of 25.2 mm, a thickness of 1.03 mm before drying, and a water swelling rate of 790% was used as a hemostatic sputum. The tourniquet was mounted and the tourniquet was made and evaluated. , - σ fruit can be used in a natural and appropriate hemostatic pad under pressure and pressure when it is not too strong or too weak. • [Example 5] The amount of the composite short fibers (10) used in Example 1 was used. /0, a card having a surface density of about 4 Gg/m2 was formed by a carding method. Send the _ to the transport network. After the comprehensive netage treatment of the net is carried out, the porous plate drum with the micropores is cut through the net, and the net is clamped from the net surface to the drum according to 2.5 M pa 100143081 35 201228630 After flowing in a columnar water stream, and then transported to the mesh of the 76 mesh, a columnar water flow treatment of 3.OMPa was performed to gently interlace the fibers. The treated web was subjected to steam treatment in the same manner as in Example 1 to obtain a nonwoven fabric in which the composite fibers were crimped and the fibers were interlaced.

The lengthwise stretch bandage (flat weave structure) is originally a sports adhesive material. When used for hemostasis, there is a strong tendency of the hemostatic pad to press and compress the force too strongly, and it is difficult to achieve a natural suitable hemostatic pad pressing force. • Stress. [Comparative Example 5] A blood-strap tape was placed on a longitudinally stretchable bandage (plain-woven structure) having no self-adhesiveness, and a hemostatic pad was placed. The lengthwise stretch bandage (flat weave structure) was originally used for the adhesive tape of Kokuji Kanaji.
