Description

  The present invention relates to a bodily fluid absorption pad that can be used repeatedly.

  2. Description of the Related Art Conventionally, a paper napkin that is one of body fluid absorbing pads that absorb menstrual blood that comes out during menstruation is well known. In most cases, this paper napkin is used only once and is thrown away in a place such as a toilet, so that the odor and bacteria generated from menstrual blood are not retained in the skin, keeping the skin clean. Can do. However, since it is necessary to replace the paper napkin after a certain amount of time has elapsed since installation, many paper napkins had to be used and discarded during the menstrual period.

In order to solve this problem, many napkins that can be used repeatedly have been devised (for example, see Patent Document 1). In addition, a urine absorption pad having the same structure as a napkin intended for repeated use has a function of absorbing and draining water depending on the temperature, so when urine absorption pad is worn, it absorbs urine and removes it with warm water above body temperature. In the case of washing, urine can be discharged, and a structure in which urine does not easily stay in the urine collecting pad has been devised (for example, see Patent Document 2).

  However, in the case of a conventional paper napkin that can be used repeatedly, the durability is increased because the menstrual blood is washed away and reused. There was a feeling of pleasure. In addition, unpleasant sensations may be felt due to odor generated by retention of menstrual blood. And since a napkin mainly absorbs menstrual blood, problems peculiar to blood, for example, blood coagulation, occur. Therefore, the urine absorbing pad cannot be used as it is for the napkin. In addition, unlike a wound pad, a napkin is not directly applied to the affected area, and thus functions caused by direct contact between the affected area and the wound pad, such as a function of a contact part for protecting the affected area (such as using a special material) ) Is not necessary for the napkin, and conversely, this function becomes a problem (for example, the touch becomes worse) for the napkin, and the wound pad cannot be used for the napkin as it is.

  Accordingly, an object of the present invention is to provide a body fluid absorption pad that can be used repeatedly, is gentle to the skin, and effectively prevents leakage of absorbed body fluid.

  In order to solve the above-mentioned problem, the body fluid absorption pad of the present invention is a body fluid absorption pad using a cloth in a portion in contact with the ground. Forming a plurality of sewing lines extending substantially in parallel with each other over the entire length of the body fluid absorption pad in the longitudinal direction or substantially the entire length of the body fluid absorption pad, and at least between the sewing lines. The absorber is provided. As a result, the pad between the sewn lines is raised on the background side and fitted between the crotch, so that the body fluid is effectively absorbed.

  Moreover, in the said structure, when the said absorber is provided in the substantially whole body fluid absorption pad, a bodily fluid is absorbed more widely.

  Further, the body fluid absorption pad is provided with a backflow prevention layer that prevents the body fluid absorbed by the absorber from being transmitted to the background side, and the absorption for absorbing body fluid on the side opposite to the background side of the backflow prevention layer. When the body is provided, the body fluid absorbed by the absorber is prevented from being transmitted to the background, so-called smoothness is given to the background.

  Moreover, when the waterproof layer is provided on the opposite side to the skin side of the absorbent body, the effect of preventing body fluid from leaking downward from the absorbent body is exhibited.

  Further, when a waterproof means is provided to prevent body fluid from leaking from the peripheral edge over the entire periphery of the peripheral edge where the absorber and the backflow prevention layer are overlapped, the absorbent is absorbed by the absorber. Demonstrates the effect of preventing body fluid from being transmitted outward from the pad.

  Further, when the cloth, the backflow prevention layer, and the absorber are sewn together by the sewing line, the cloth, the backflow prevention layer, and the absorber are integrally raised on the background side. In addition, the body fluid that oozes out from the sewing line is prevented from oozing out below the waterproof layer.

  Further, in a body fluid absorption pad using a cloth for a portion in contact with the ground, an absorbent for absorbing body fluid is provided on substantially the entire body fluid absorption pad so that the body fluid absorbed by the absorber does not reach the skin side. A backflow prevention layer is provided, a waterproof layer is provided on the side opposite to the skin side of the absorbent body, and the body fluid has a peripheral edge over the entire circumference of the peripheral edge where the absorber and the backflow prevention layer are overlapped. A waterproof means for preventing leakage from the portion is provided. Thereby, the effect | action which prevents a bodily fluid oozes out from the perimeter part perimeter of the said absorber and the said backflow prevention layer is exhibited.

  In addition, the body fluid absorption pad was formed from five layers of the cloth, the backflow prevention layer, the absorber, the waterproof layer, and the bottom layer using the cloth in order from the side in contact with the ground. In this case, the body fluid can be absorbed more efficiently, and the function of preventing the body fluid from leaking to the outside of the pad is exhibited.

  Further, when the backflow prevention layer has a photocatalyst, it exerts an action of eliminating or sterilizing the odor generated from the body fluid.

  Even when the pad is misaligned, such as when walking, the pad between the sewn lines can be raised to the skin side, and it can be fitted between the crotch, so that the body fluid can be absorbed effectively. . Moreover, it can prevent that a bodily fluid leaks from the perimeter part periphery of an absorber and a backflow prevention layer.

  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a part of the configuration of a cloth napkin as an example of the body fluid absorption pad of the present invention in cross section. (A) is a perspective view, (b) is a sectional view, and (c) is a partially enlarged sectional view. 2A and 2B are diagrams of the mounted state, where FIG. 2A is a perspective view and FIG. 2B is a cross-sectional view when viewed from the front.

  As shown in FIG. 1, the cloth napkin 1 is formed of a pad 2 and blades 3 and 4. The pad 2 has a substantially oval shape, and both side edges of the pad 2 are slightly curved inward. . Slightly semi-circular blades 3 and 4 are attached to the front side of the center of the pad 2 in the longitudinal direction. The blades 3 and 4 are provided at symmetrical positions with the pad 2 interposed therebetween, and the pad 2 can be fixed to the underwear 5 (see FIG. 2) by the locking means 16 and 17. The locking means 16 and 17 are attached to the end portion on the side not attached to the pad 2 in the vicinity of the substantially center portion in the front-rear direction of the blade. Plural locking means 16 are arranged substantially perpendicular to the longitudinal direction of the pad 2, and can be adjusted so that the pad 2 can be attached to the underwear 5 depending on the size of the underwear 5 when locking with the locking means 17. Is provided. Further, a substantially annular hanging portion 18 is provided in the vicinity of the substantially central portion of the front end of the pad 2 so that the cloth napkin 1 can be suspended. Further, in order to give a certain degree of hardness inside the blades 3 and 4, interlinings 19 and 20 are provided over substantially the entire blades 3 and 4.

  The pad 2 has a structure mainly having five layers. The first layer 6 (uppermost layer) on the uppermost side (the side that touches the background is the upper side) is formed of cloth raised fabric, and no uncomfortable feeling is produced when the first layer 6 comes into contact with the background. So that it is made of soft fabric. The second layer 7 (backflow prevention layer) therebelow is made of, for example, mesh ground. Moreover, you may have a photocatalyst in this mesh ground. In this case, the deodorization and bactericidal action, which is one of the characteristics of the photocatalyst, can eliminate the odor generated by menstrual blood when the pad 2 is exposed to light, reduce the bacteria in the first layer 6, and reduce the first It is possible to reduce the adhesion of bacteria to the ground where the layer 6 contacts. Since the second layer 7 is a mesh fabric knitted with thread-like fibers having a photocatalyst, menstrual blood passes through the stitch as shown in FIG. 8 (absorbing layer). The third layer 8 is formed of an absorbent that can absorb menstrual blood that has passed through the second layer 7, and the absorber is a fabric that can absorb menstrual blood well, such as cotton, super absorbent fibers, non-woven fabric, Paper cloth is used. The fourth layer 9 (waterproof layer) under the third layer 8 is waterproofed so as not to pass menstrual blood, and menstrual blood that has passed through the third layer 8 from the first layer 6 is further reduced. The lower layer is prevented from going (arrow in FIG. 1 (b)). This waterproofing process is formed by the fabric itself of the fourth layer 9 having a waterproof effect or the surface of which is subjected to waterproof coating or the like. And in the 5th layer 10 (lowermost layer), although it is formed with the raising ground substantially the same as the 1st layer 6, unlike the 1st layer 6, since it does not touch the ground directly, It may not be used. Further, since the first layer 6 is formed between the second layer 7 and the background, it is possible to prevent a background disease (such as rash) caused by the deodorization and antibacterial action of the photocatalyst.

  Further, two pads 2 formed in this layer shape are sewn with two first sewing lines 11 and 12 substantially parallel to the longitudinal direction, and the first sewing lines 11 and 12 are arranged in the width direction of the pad 2. It is formed in the vicinity of the center so that the width direction is substantially equally divided. As shown in FIG. 1, the first sewing lines 11 and 12 are integrated by sewing from the first layer 6 to the third layer 8, and the fourth layer 9 and the fifth layer 10 are sewn. Not. This is because menstrual blood does not pass through the fourth layer 9 even if it passes through the threads of the first sewing lines 11 and 12 and passes from the first layer 6 to the third layer 8. Further, as shown in FIG. 1C, the peripheral portion of the pad 2 has a five-layer structure like the central portion, but the peripheral portion includes the first layer 6, the second layer 7, and the third layer. 8, the fourth layer 9 and the fifth layer 10 are sewn together so as to make the contact with the background as soft as possible, and the first layer 6 (the uppermost layer) and the fifth layer 10 (the uppermost layer) Since the waterproofed fourth layer 9 is provided between the lower layers), menstrual blood can be prevented from penetrating directly into the fifth layer 10. The second layer 7 and the third layer 8 can be prevented from shrinking by washing or the like by sewing the first layer 6 to the fifth layer 10, but the first layer 6, the fourth layer 9. Only the fifth layer 10 may be sewn.

  In addition, the first layer 6 to the fifth layer 10 of the pad 2 and the blades 3 and 4 are aligned with each other at the peripheral edge, and the left and right blades 3 and 4 are inside each other when the cloth napkin 1 is fixed to the underwear 5. Each is sewn so as to face (to the center in the width direction).

  Further, on the peripheral side of the first sewing lines 11 and 12 of the pad 2, a substantially arcuate shape is included in a range including the attachment portions of the blades 3 and 4 at positions facing each other across the first sewing lines 11 and 12. Second sewing lines 14 and 15 are formed. Similarly to the first sewing lines 11 and 12, the second sewing lines 14 and 15 are integrated by sewing from the first layer 6 to the third layer 8, and the fourth layer 9 and the fifth layer 10 are integrated. Is not sewn. This is because menstrual blood does not pass through the fourth layer 9 even if it passes through the thread from the first layer 6 to the third layer 8 as described above. And unlike the 1st sewing line 11 and 12, when wearing the pad 2 by forming in a substantially circular arc shape at the both ends of the width direction of the pad 2, with this 2nd sewing line 14 and 15, The pad 2 is easily bent downward, and the pad 2 can be further fitted between the crotch during walking. And the 3rd layer 8 can be provided only between the 1st sewing line 11 and the 1st sewing line 12, and it can also improve the fitting property with respect to the background.

  Further, a waterproof sheet 23 formed in a substantially annular shape so as to prevent body fluid from being transmitted to the outside over the entire circumference of the peripheral edge where the second layer 7 and the third layer 8 of the pad 2 are overlapped, It is provided so as to sandwich the layer 7 and the third layer 8. The waterproof sheet 23 is sewn over the entire circumference of the peripheral edge overlapped with the second layer 7 and the third layer 8. When the menstrual blood (indicator) shown in FIG. 1 (b) is stored in the third layer 8 that can store menstrual blood most by this waterproof sheet 23, it is shown in FIG. 1 (c). Even if menstrual blood is transmitted to the end portion of the third layer 8, it can be prevented from oozing out from the peripheral portion of the pad 2.

  As shown in FIG. 2, as a method of attaching the cloth napkin 1, the cloth napkin 1 is pressed to an appropriate position of the crotch portion of the underwear 5 with the blades 3 and 4 open, and the blades 3 and 4 are attached to the underwear 5 Are alternately attached to the back side of the crotch portion, and fixed to the crotch portion of the underwear 5 by the locking means 16 and 17 attached to the blades 3 and 4. Since the interlinings 19 and 20 are provided inside the blades 3 and 4, when being fixed to the crotch portion of the underwear 5, it is possible to eliminate dubbing due to twisting and the like so that the fixing can be ensured. It has become. As a result, the winged blades 3 and 4 do not cling to the thigh 13 and the feeling of discomfort is reduced.

  FIG. 3 is a view showing the state of the pad when walking after wearing the cloth napkin, (a) is a plan view schematically showing the state seen from above, and (b) is the upper side. It is sectional drawing which showed typically when menstrual blood etc. dripped from. FIG. 4 is a plan view of a walking state after wearing a cloth napkin without a first sewing line, as viewed from above.

  As shown in FIG. 3, by using a cloth for the first layer 6, the first sewing lines 11 and 12 provided in the vicinity of the center portion in the width direction of the pad 2 are in walking (in the figure, the arrow indicates the thigh When the thighs 13 are alternately moved back and forth such as indicating the moving direction of the parts), the heel 21 can be generated between the two first sewing lines 11 and 12, and the first layer 6 to the third Up to layer 8 can be raised like a raised portion 22. Accordingly, the first layer 6 can be fitted to the crotch, and even if the pad 2 is displaced from a predetermined position, the crotch can be fitted to the raised portion 22, and menstrual blood can be absorbed from the raised portion 22. be able to. If the first sewn lines 11 and 12 do not exist, as shown in FIG. 4, the heel 21 reaches the left and right ends of the pad 2, and a gap is generated between the ground and the first layer 6. Menstrual blood leaks from the gap.

  5A and 5B are perspective views when the cloth napkin is folded, in which FIG. 5A is a view in which the front and back of the pad are folded with the blades as a boundary, and FIG. 5B is a view in which the blades are wrapped from above (a).

  As shown in FIG. 5A, when the cloth napkin 1 that has absorbed menstrual blood is carried in a plastic bag or the like, the blades 3 and 4 of the pad 2 are attached so that the cloth napkin 1 is not bulky. 5, the front side and the rear side are alternately folded upward so as to wrap the surface to which menstrual blood is adhered, and then the folded front and rear pads 2 are formed as shown in FIG. 2, the blades 3, 4 wrap the pad 2 alternately from the left and right from the outside, and the right and left blades 3, 4 are stopped and fixed by the locking means 16, 17. Thereby, an area becomes about 1/3 at the time of pad 2 wearing, it is not bulky at the time of carrying, and when taking out from the accommodated plastic bag etc., it can reduce making a hand and clothes dirty. In order to make it easy to dry the cloth napkin 1 after washing, an annular hanging portion 18 is provided at the front end of the pad 2 (see FIG. 1). A string is passed through the hanging portion 18 or a clothespin is used. By sandwiching the pad 2 itself, the pad 2 itself is not compressed with a clothespin or the like, and the leakage of menstrual blood due to deformation of the shape at the time of wearing can be reduced. The attachment position of the hanging portion 18 is not limited to the front end of the pad 2, and may be attached to the rear end or side end of the pad 2, or the outer peripheral ends of the blades 3, 4, for example. Moreover, it can utilize also as a mark of the attachment direction of a cloth napkin by attaching the hanging part 18 to the front end of the pad 2 (refer FIG. 1). And the latching means 16 and 17 should just be the structure which can attach the blade | wings 3 and 4 to underwear, and a hook, a magic tape (trademark), a double-sided tape, a button etc. may be used. At this time, a plurality of attachments such as the locking means 16 can be attached so that attachment to the underwear can be adjusted.

  Moreover, you may use for a breast milk pad and a panty liner instead of the cloth napkin which is a bodily fluid absorption pad. And in this invention, although the blade | wing for attaching a cloth napkin to underwear is provided, you may attach to underwear directly with a double-sided tape etc., without providing a blade | wing.

  It can be used to prevent body fluids such as menstrual blood, milk, urine and the like from adhering to worn clothing such as underwear.
