DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the package of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.
[0015]
FIG. 1 is a plan view (internal perspective view) showing an embodiment of the package of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG. In the following description, the upper side in FIG. 1 (the same applies to FIGS. 3 and 4) is referred to as the “base end” and the lower side is referred to as the “tip”.
[0016]
First, each element which comprises the package 1 is demonstrated.
As shown in FIG. 1 and FIG. 2, a packaging body 1 of the present invention includes a catheter 3 that is a long instrument used by being inserted into or attached to a living body in a packaging material 2, and a container in which a liquid is sealed. 4 and an absorbent body 5 capable of absorbing and holding the liquid are accommodated.
[0017]
The packaging material 2 is composed of a pair of opposing sheet materials 2a and 2b. As shown in FIG. 2, one sheet material 2 a has a flat shape, and the other sheet material 2 b has a desired pattern protruding shape corresponding to the shape of the catheter 3, container 4, and absorber 5 to be accommodated. (Blister shape), the two sheet materials 2a and 2b are overlapped, and the outer peripheral portions thereof are fused (heat fusion, high frequency fusion, ultrasonic fusion, etc.) or bonded (by an adhesive or a solvent). Sealed by bonding). A storage space 20 for the packaging material 2 is formed in a space surrounded by the seal portion 21.
[0018]
Sheet materials (films) 2a and 2b constituting the packaging material 2 are not particularly limited. For example, polyolefin resins such as polyethylene and polypropylene, blend resins of these polyolefin resins, polyester resins such as polyethylene terephthalate, polyvinylidene chloride, A monolayer film such as a vinyl chloride-vinylidene chloride copolymer, a film obtained by vapor-depositing aluminum or silica on these films, a metal foil such as an aluminum film or an aluminum laminate film, or a film containing a metal foil can be used. Furthermore, what laminated | stacked these each film 2 layers or more can also be used. Further, a plastic nonwoven fabric or paper may be used as the sheet material.
[0019]
The sheet materials 2a and 2b may have the same configuration (material) or different configurations (materials). For example, one of the sheet materials 2a and 2b may be made of a harder material than the other.
[0020]
Moreover, in order to ensure the visibility of the contents, it is preferable that at least one of the sheet materials 2a and 2b is transparent.
[0021]
The thickness of the sheet material (single layer or multilayer laminate) constituting the packaging material 2 is appropriately determined according to the layer configuration and the characteristics of the material used (flexibility, strength, water vapor permeability, heat resistance, etc.), etc. Although it is not particularly limited, it is usually preferably about 60 to 700 μm, more preferably about 100 to 500 μm.
[0022]
Examples of the sheet material constituting the packaging material 2 include an inflation method, a T die method, a blow molding method, a dry lamination method, a hot melt lamination method, a coextrusion inflation method, a coextrusion T die method, a hot press method, and the like. It can be manufactured by various methods.
[0023]
The catheter 3 accommodated in the packaging material 2 has an insertion portion 31 inserted into the living body and a base portion 32 for operating the catheter 3 by hand. The insertion part 31 is preferably composed of a flexible tube. A flexible tip member 34 having a side hole 35 is provided at the tip of the insertion portion 31.
[0024]
The insertion portion 31 is required to be smoothly inserted into the living body. For this reason, the whole or a part of the surface of the insertion portion 31 is provided with a substance that exhibits lubricity due to wetting. Is preferred.
[0025]
Examples of such substances include hydrophilic polymers as described in JP-A-60-259269 and JP-A-1-195863. Also, for example, Japanese Patent Publication No. 6-32652, Japanese Patent Application Laid-Open No. 6-7426, International Application WO88026223, International Application WO8907521, International Application WO8909246, International Application WO900019289, International Application WO9219289, International Application WO93129721, International Application WO9529722, Substances and methods disclosed in No. -50854, No. 10-502855 and No. 10-502856 may be used. Such a substance is usually present on the surface of the insertion portion 31 in a wet state (dry state).
[0026]
Such a substance is a polymer chemically bonded to the surface of the base material of the insertion portion 31, and is difficult to peel off from the surface of the base material and to elute into water, physiological isotonic fluid, other lubricants, etc. Is preferable from the viewpoint of durability and safety of lubricity.
[0027]
For this reason, prior to the use of the catheter 3, the liquid 43 ejected from the container 4 is brought into contact with the insertion portion 31, and lubricity is exhibited by wetting. Accordingly, the insertion portion 31 constitutes a liquid contact portion that requires contact with the liquid 43.
[0028]
On the other hand, since the base portion 32 of the catheter 3 is a hand-held portion, if it is wet with the liquid 43, it is slippery, the operability of the catheter 3 is reduced, and the liquid also adheres to the hand, which is not preferable. . Therefore, the base portion 32 constitutes a liquid contact-free portion that does not require contact with the liquid 43 (particularly, dislikes contact with the liquid 43).
[0029]
The base portion 32 functions as a connector, and has a branch portion 33 that branches obliquely laterally. However, it goes without saying that the shape is not limited to such a shape.
[0030]
The type, use, etc. of the catheter 3 accommodated in the packaging material 2 are not particularly limited. For example, the trachea, digestive tract, urethra, vagina, blood vessel, lymphatic vessel, bile duct, other body cavities, for example, lung, heart And various catheters and balloon catheters inserted into various organs such as kidneys and other living tissues. Among these, a catheter (urinary catheter, urinary catheter) used by being inserted into the urethra is particularly preferable.
[0031]
As a urinary tract method for dysuria, a sterile intermittent urinary method is preferable instead of an indwelling catheter, but in recent years, self urination in which a patient discharges urine by using a catheter has become widespread as an effective treatment method. Urinary dysfunction is caused by urinary tract obstruction due to benign prostatic hyperplasia, stones, tumors, etc., or neurogenic bladder seen in disorders such as the brain, spinal cord, and pelvic nerves. Since the internal pressure increases and puts a burden on the kidneys, it is necessary to drain urine regularly. The self-conduction method performed at this time can drain urine completely at low pressure, so there are advantages such as reduction of existing urine infection, frequent urination, urinary incontinence cure, no burden on the bladder and kidneys, etc. The patient himself / herself inserts a catheter into the bladder from the urethra about 4-6 times a day, and removes the urine after draining is completed. The frequency is, for example, every 4 to 5 hours in the daytime and before going to bed at night.
[0032]
Therefore, if the catheter base part (wetless part) 32 can be kept wet with the liquid 43 (dry state), the operability of the catheter 3 is improved for a patient unfamiliar with the handling of medical instruments. Thus, it is possible to perform self urination more easily and reliably. Similarly, it also contributes to improving the efficiency of work for healthcare professionals.
[0033]
The container 4 is formed into a bag shape by fusing (or adhering) both ends of a sheet material (inflation sheet material) formed into a cylindrical shape. In addition, the container 4 is not limited to what was formed in this way, For example, the center part of a flat sheet material is bend | folded, and three sides are fuse | melted (or adhere | attached), and it was a bag shape, or two sheets A bag may be formed by stacking materials and fusing (or adhering) the entire outer periphery thereof. A liquid 43 as will be described later is sealed in the container 4.
[0034]
By selecting the capacity of such a container 4, the amount and weight of the liquid 43 in the container 4 can be easily set, and the container 4 can be manufactured independently, so that it can be manufactured and managed. easy.
[0035]
The container 4 is formed with a seal portion serving as an opening 41 at the base end portion and a seal portion 42 at the distal end portion. In the present invention, the structure and the like of the container 4 are not particularly limited as long as the container 4 can be easily and reliably opened.
[0036]
The seal width of the opening 41 is formed to be narrower than the seal width of the seal portion 42. For this reason, for example, when the container 4 is pressed (squeezed) from the outside of the packaging material 2, the seal portion that becomes the opening 41 is easily and reliably peeled (broken) from the seal portion 42. Thereby, the container 4 can eject the liquid 43 from the opening 41.
[0037]
Note that the opening 41 may be configured such that a part of the seal portion is a weak seal portion whose bonding strength (peeling strength) is weaker than other portions. Thereby, the opening 41 is peeled off more easily and reliably. Further, depending on the shape of the weak seal portion to be formed, it is possible to improve the directivity in the ejection direction of the liquid 43 ejected from the container 4. However, even when the opening 41 is formed in this way, liquid tightness (airtightness) is ensured in the state before opening.
[0038]
The sheet material (film) constituting the container 4 is not limited except for paper and non-woven fabric, and the same material as the sheet material constituting the packaging material 2 can be used.
[0039]
The thickness of the sheet material (single layer or multilayer laminate) constituting the container 4 is appropriately determined according to the layer configuration and the characteristics of the material used (flexibility, strength, water vapor permeability, heat resistance, etc.), etc. Although not particularly limited, it is usually preferably about 60 to 700 μm and more preferably about 100 to 500 μm.
[0040]
Examples of the sheet material constituting the container 4 include an inflation method, a coextrusion inflation method, a T die method, a blow molding method, a dry lamination method, a hot melt lamination method, a coextrusion T die method, and a hot press method. It can be manufactured by various methods.
[0041]
The liquid 43 stored in the container 4 is preferably a substance (liquid or semi-liquid) that can contact the surface of the insertion portion 31 of the catheter 3 and reduce its frictional resistance.
[0042]
Although it does not specifically limit as the liquid 43, For example, oils, such as water, physiological isotonic solution (physiological saline), glycerin, silicone oil, olive oil, xylocaine jelly, etc. are mentioned.
[0043]
Further, in the case where the surface of the insertion portion 31 of the catheter 3 is provided with a substance that exhibits lubricity as described above, the liquid 43 may be any liquid that can wet the substance. For example, water, physiological isotonic solution (physiological saline), glycerin aqueous solution and the like are more preferably used.
[0044]
The absorber 5 is a liquid absorber that can absorb and hold the liquid 43 and the like. By storing the absorbent body 5 in the packaging material 2, the absorbent body 5 absorbs and holds the excess liquid 43 after contacting the insertion portion (liquid contact portion) 31 of the catheter 3 and the liquid 43. Is possible. Therefore, the possibility that the base 32 of the catheter 3 comes into contact with the liquid 43 and gets wet becomes lower.
[0045]
Although it does not specifically limit as the absorber 5, For example, synthetic polymers, such as a polyacrylate type, polyvinyl alcohol type, polyacrylamide type, polyoxyethylene type, or a maleic acid type material, starch, cellulose, alginic acid etc. Those composed of a polymer absorbing material such as a natural material such as a polysaccharide material are preferred. In addition, for example, sponges, cotton, gauze, non-woven fabrics, and those carrying the polymer water-absorbing material thereon (for example, those used in diapers, sanitary products, etc.) are also possible. Such an absorbent body 5 can take a form (shape) such as a block shape, a powder shape, a film shape, a sheet shape (plate shape), and a fiber shape.
[0046]
Next, the storage position of the catheter 3, the container 4, and the absorber 5 in the packaging material 2 and the position of the packaging material opening portion 22 included in the packaging material 2 will be described.
[0047]
As shown in FIG. 1, the packaging material 2 has seal portions 21 near the proximal end and the distal end of the catheter 3 housed therein. For this reason, the catheter 3 is restricted from moving in the longitudinal direction in the packaging material 2. That is, the catheter 3 can move only a short distance in the longitudinal direction.
[0048]
Further, the packaging material 2 includes a wall portion 24 formed by the seal portion 21 in the vicinity of the proximal end of the container 4 accommodated therein, a protruding portion 25 formed by the seal portion 21 in the vicinity of the distal end, and seals in the vicinity of both sides. Each part 21 exists. For this reason, movement of the container 4 in the packaging material 2 is restricted in the vertical and horizontal directions in the figure.
[0049]
By setting the positions of the wall portion 24 and the projecting portion 25, the position of the opening 41 of the container 4 with respect to the longitudinal direction of the catheter 3 can be arbitrarily determined within the packaging material 2.
[0050]
In this embodiment, the opening 41 is located in the range of the insertion part (liquid contact part) 31 of the catheter 3 or in the vicinity of the side part. When the opening 41 is in such a position, the insertion portion (liquid contact portion) 31 of the catheter 3 can be quickly and uniformly wetted with the liquid 43.
[0051]
Further, the wall portion 24 is formed so as to be inclined (tapered) so that the distance from the tip of the packaging material 2 is short on the outside and long on the inside. For this reason, the liquid 43 ejected from the opening 41 that does not collide with the wall portion 24 can efficiently wet the proximal end side of the insertion portion (required liquid portion) 31 of the catheter 3. On the other hand, what collided with the tapered wall portion 24 is relaxed at the wall portion 24, and scattered at a wide angle toward the side, that is, the insertion portion (liquid contact portion) 31, The remaining part of the insertion part (liquid contact part) 31, particularly the intermediate part, can be efficiently wetted. Therefore, the liquid 43 spreads evenly in the longitudinal direction of the insertion portion (liquid contact portion) 31, and the wide range of the insertion portion 31 can be wetted more uniformly.
[0052]
In addition, as a form (shape, structure, etc.) of a wall part, it is not limited to what was illustrated, For example, the wall part substantially orthogonal to the ejection direction of the liquid 43 ejected from the opening 41 may be sufficient. Thereby, the ejection to the direction which does not want to get wet can be controlled, and the insertion part (liquid-contact part) 31 can be wetted uniformly.
[0053]
Further, the wrapping material 2 has the protruding portion 25 near the proximal end of the absorber 5 housed therein and the seal portion 21 near the distal end. For this reason, as for the absorber 5, the movement of the longitudinal direction of the catheter 3 in the packaging material 2 is regulated to some extent.
[0054]
By setting the position of the protruding portion 25, the position of the absorbent body 5 with respect to the longitudinal direction of the catheter 3 can be arbitrarily determined within the packaging material 2.
[0055]
In the present embodiment, the absorber 5 is located at the distal end portion of the catheter 3. Thereby, after the liquid 43 ejected from the container 4 sufficiently comes into contact with the insertion portion 31 of the catheter 3, the excess liquid 43 is absorbed and held by the absorber 5, and the utilization efficiency of the liquid 43 is improved. Good.
[0056]
In the packaging material 2, the packaging material opening portion 22 has a side opposite to the opening 41 of the container 4, that is, a base portion of the catheter 3 (no liquid contact is required) with respect to an easily bent portion 26, which will be described later. Part) 32.
[0057]
This packaging material opening part 22 pulls the pair of peel tabs 23, 23 formed without sealing the base ends of the above-mentioned sheet materials 2a, 2b in the opposite directions, thereby removing the sealing part 21 of the packaging material opening part 22 from each other. It can be peeled and opened.
[0058]
Since the packaging material opening portion 22 is located in the vicinity of the base portion (liquid contact-free portion) 32 of the catheter 3, the packaging material in which the catheter 3 is opened after the insertion portion (liquid contact portion) 31 is wetted with the liquid 43. When taking out from the opening part 22, it can prevent more effectively that the base 32 contacts the liquid 43 and gets wet.
[0059]
The configuration of the packaging material opening part is not limited to the one shown in the figure. For example, a structure in which a notch is formed at the edge of the packaging material, and the packaging material 2 is torn and opened from the notch part. It may be.
[0060]
In the present invention, the packaging material 2 has a liquid blocking means. Details will be described below.
[0061]
3 and 4 are side views (internal perspective views) showing the embodiment of the present invention. Among these, FIG. 3 is a figure which shows the state before folding the package body 1 in the easy folding part 26, and FIG. 4 is a figure which shows the state after folding the packaging body 1 in the easy folding part 26. FIG. is there.
[0062]
The liquid blocking means can easily block the flow of the liquid 43 ejected from the container 4.
[0063]
As the liquid blocking means, the packaging material 2 is composed of, for example, an easily bent portion that can be easily bent, an easily ligated portion that can be easily squeezed, an easily twisted portion that can be easily twisted, and the like. In the present embodiment, the liquid blocking means is constituted by the easily bent portion 26.
[0064]
The easy bending part 26 is comprised by the bellows shaping | molding part shape | molded by the bellows shape. As a result, as shown in FIG. 3, the storage space 20 in the packaging material 2 is defined narrower in the portion of the easily bent portion 26 than in other portions. In addition, as shown in FIG. 4, when the packaging body 1 is folded at the easy-bending portion 26, the sheet material of the bellows forming portion closes or narrows the storage space 20 in the range of the easy-folding portion 26. can do. For this reason, the flow of the liquid 43 ejected from the container 4 is blocked by the easy-bending portion 26, and the base portion (a wetted portion) 32 of the catheter 3 can be prevented from coming into contact with the liquid 43 and getting wet.
[0065]
Although it does not specifically limit as a bending angle in the easy bending part 26, It is preferable that angle (theta) shown in FIG. 4 can be bend | folded to 90 degrees or more. If the angle can be bent to 90 °, the barrier property of the liquid 43 at the easy bending portion 26 is further improved.
[0066]
Such an easy-bending part 26 is located between the opening 41 of the container 4 and the base part (wetless part) 32 of the catheter 3. In particular, the easily bent portion 26 is preferably located in the vicinity of the base portion (a wetted portion) 32 as illustrated. By providing the easy-bending portion 26 at such a position, the insertion portion 31 can be wetted to the proximal end as much as possible.
[0067]
In addition, as a method for forming the easy bending portion 26, there are a sheet molding method, a thermoforming method, and the like. For example, vacuum molding, pressure molding, vacuum pressure molding, plug assist molding, plug assist vacuum molding, plug assist Pressure molding, plug-assist vacuum / pressure molding, blister molding, male molding and the like are used.
[0068]
Next, an example of the usage method (action) of the package 1 described above will be described.
For example, as shown in FIG. 3, the packaging body 1 is bent at 90 °, for example, at 90 ° from the state in which the packaging body 1 is horizontal, as shown in FIG. 4. So that it faces vertically upward. In addition, the package 1 can be bent at 90 ° to 180 ° at the easy bending portion 26. As a result, the storage space 20 in the range of the easily bent portion 26 is closed or narrowed. For this reason, the liquid 43 ejected from the container 4 cannot pass through the easily bent portion 26.
[0069]
In addition, the flexible insertion portion 31 of the catheter 3 is located in the easy bending portion 26. For this reason, the packaging body 1 can bend the packaging material 2 together with the catheter 3 in the easy bending portion 26.
[0070]
Next, the container 4 is pressed and pressed from the outside of the packaging material 2 with a finger or the like while the packaging body 1 is maintained in the state described above. Thereby, the seal part of the opening 41 of the container 4 is peeled (broken), and the liquid 43 in the container 4 is ejected from the opening 41.
[0071]
A part of the liquid 43 ejected from the opening 41 directly goes to the proximal end side of the insertion portion (liquid contact portion) 31 and collides with the wall portion 24. Scatters at a relatively wide angle to the side. As a result, the liquid 43 spreads in the longitudinal direction of the insertion portion 31 of the catheter 3 and uniformly wets at least the proximal end portion of the insertion portion 31. At this time, since the package 1 is bent at the easy bending portion 26, the liquid 43 is prevented from passing over the easy bending portion 26 to the proximal end side. Therefore, the base part (wetless part) 32 of the catheter 3 is almost not wet with the liquid 43, or even if it gets wet, the tip side is only partially wetted.
[0072]
Moreover, you may perform operation, such as raising / lowering the base end side and front end side of the insertion part 31 alternately as needed, keeping the package 1 in the state mentioned above. Thereby, the liquid 43 adhering to the surface of the insertion portion 31 reciprocates between the proximal end side and the distal end side along the surface of the insertion portion 31, and from the proximal end portion to the distal end portion of the insertion portion 31. Can be evenly wet evenly.
[0073]
Furthermore, the front-end | tip of the package 1 in a horizontal state is made to face a vertically downward direction as needed. That is, it is set as the attitude | position which the base end of the package 1 faces vertically upward, and a front-end | tip faces vertically downward. Thereby, the liquid 43 adhering to the surface of the insertion portion 31 flows down along the surface of the insertion portion 31 and can be evenly and evenly wetted to the tip of the insertion portion 31. In particular, the outer surface of the tip member 34 can be wetted.
[0074]
Then, the surplus liquid 43 is absorbed and held by the absorbent body 5 installed at the front end portion in the packaging material 2. Thereby, for example, even when the base end of the package 1 is directed vertically downward, the base portion 32 of the catheter 3 can be prevented from coming into contact with excess liquid and getting wet.
[0075]
As described above, when the surface of the insertion portion (liquid contact portion) 31 gets wet with the liquid 43, the surface of the insertion portion 31 exhibits lubricity and frictional resistance is reduced.
[0076]
After opening the opening 41 of the container 4, if necessary, an operation is performed to discharge all the liquid 43 in the container 4 by pressing (squeezing) the outer side of the packaging material 2 with a finger or the like. Also good.
[0077]
The inside of the packaging material 2 and the inside of the container 4 have been sterilized in advance, and the operation of expressing lubricity on the surface of the insertion portion 31 of the catheter 3 by contact with the liquid 43 is a sealed packaging material. The catheter 3 can maintain sterility because it is performed in the second storage space 20 without contact with outside air. Furthermore, the base portion (wetless part) 32 of the catheter 3 is kept in a dry state.
[0078]
As described above, when the surface of the insertion portion (required liquid portion) 31 of the catheter 3 is wetted by the liquid 43 and develops lubricity, the packaging material opening portion 22 of the packaging material 2 is peeled (broken) and opened. To do.
[0079]
Then, the base 32 of the catheter 3 is held by hand, and the catheter 3 is taken out from the packaging material 2.
