Description

EXAMPLE 6 ' 193 / RAZ

Hydrophilic urinary catheter with water-containing bag

The present invention relates to a wetting device for wetting a hydrophilic urinary catheter comprising a wetting fluid receiving container suitable for receiving a hydrophilic urinary catheter as well as a fluid reservoir for wetting a hydrophilic urinary catheter, having an opening open from a closed position to an open position under a predetermined condition for application, allowing the wetting fluid to flow out of the wetting fluid reservoir to the wetting fluid receiving area, thereby wetting the hydrophilic urinary catheter. The invention further relates to a type of liquid container that can be used for this device.

Periodic so-called self-catheterization is widely used in patients who suffer from stricts or traumas in the urinary system, for example, and in paralyzed patients, to be able to live close to normal home. Urinary catheters available for periodic self-catheterization generally require a lubricant to be applied to the outer surface of the catheter to facilitate insertion into the urethra. For example, hydrophilic urinary catheters have a hydrophilic outer surface coating that is wetted for lubrication with a fluid such as water or saline for a period of time before being inserted into the urethra of the patient.

Various methods have been proposed for lubrication of urinary catheters, which are given below.

A prior art USP 5209726 discloses a self-lubricating urinary catheter and a self-catheterization process. The catheter has an annular lubricating fluid container that surrounds an inner tube with perforations. When the catheter is inserted into the urethra of the patient, the lubricant is forced from the reservoir into the inner tube and exited therefrom through the outlet in the catheter. Lubrication of the outer surface of the catheter therefore occurs only upon insertion into the urethra of the patient, at least causing some initial discomfort to the patient when inserting the catheter.

Previous USP 3967728 discloses a catheter package consisting of a urethral catheter and a breakable pouch containing a lubricant. One edge of the pouch is placed inside the package, near the tip of the catheter, and the sealing seal at this edge is configured to burst when the pouch is compressed, thereby lubricating the tip of the catheter. Since only the tip of the catheter is lubricated, the patient should also bear the discomfort when inserting the catheter into the urethra.

The former UK 2284764 discloses an assembly comprising a catheter and a urine collection bag comprising a catheter with a rounded tip, with a tip opening and a widening portion towards the back of the stem, the catheter being located in the urine collection bag, the front end can be shaped and provided with an opening large enough to allow the tip and stem of the catheter to pass through, but small enough to form a mechanical seal against the urine leakage with the widening portion of the catheter. Once the catheter has passed through the opening, it is ready for delivery to the patient's urethra. Urine is transported backwards through the catheter from the patient's bladder to the urine collection bag. It has also been described that a separate, foldable container containing a lubricant may also be present in the urine collection bag for lubrication of the catheter. However, no details are given regarding the design of the container or the position of the container relative to the catheter.

In the prior art, WO86 / 06284, the Applicant discloses a wetting and storage device for a hydrophilic urinary catheter. Here, a wetting pocket is used near one end so that it can be filled with a wetting fluid, and a hydrophilic urinary catheter is introduced into this pocket for wetting it. However, there is no liquid container in the device for delivering the wetting fluid to the pocket immediately before the catheter is used. Therefore, the patient should fill the wetting fluid separately in the pocket. This is inconvenient because the sterile filling of the wetting fluid is not always provided to the patient and there is a great potential for the wetting fluid to spill out.

The disadvantage of the lubricating devices proposed to date for the urinary catheters discussed above is that they do not or only provide less lubrication of the hydrophilic urinary catheters. For example, it is

USP 3967728 and UK 2284764 discloses lubricating devices for non-hydrophilic catheters in which the lubricant is a gel which does not correspond to lubrication of hydrophilic catheters. The prior art lubricating devices therefore do not provide a combined application for the administration of a hydrophilic urinary catheter wetting fluid, even less for the administration of a hydrophilic urinary catheter wetting fluid, which, when dispensed, moisturizes the hydrophilic catheter insertion length, or at least substantially its entire length, prior to introducing the catheter into the patient's urethra.

Patients using a hydrophilic urinary catheter need improved catheter wetting. The present invention therefore proposes to solve this problem.

According to a first aspect of the present invention, the wetting device of the present invention is for wetting a hydrophilic urinary catheter having a wetting vessel with a wetting fluid intake area receiving the hydrophilic urinary catheter, and a reservoir receiving a hydrophilic urinary catheter wetting fluid having a closed position to be moved to an open position, * allowing, under a predetermined condition, the outflow of the wetting fluid from the wetting fluid reservoir, wherein the wetting fluid container is combined or combined with the wetting vessel in the operating position when at least the wetting fluid container outlet is located within the limits of the wetting container, and the wetting container is designed and the wetting fluid container is positioned relative to the wetting container in its operating position, that the wetting fluid reservoir output, when using a predetermined condition, in the position of its operation ··· · · J * · · ··· · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · and wetting fluid receiving area is sized and configured for the hydrophilic urinary catheter to allow the hydrophilic urinary catheter to be inserted, or at least wettable by the wetting fluid applied to the wetting fluid receiving area.

The term "integrated" means that the wetting fluid reservoir and the wetting container device are a single piece unit, i.e. the wetting fluid container is carried by the wetting container.

A trapped lubricant supply to the hydrophilic urinary catheter is therefore available to the patient and the problem of the possibility of wetting fluid leakage is reduced. Furthermore, the increased comfort of the catheter in the urethra is due to the inlet length of the catheter being lubricated prior to introduction.

In another aspect of the invention, the wetting device for wetting a hydrophilic urinary catheter according to the present invention has a wetting container with a wetting fluid receiving area receiving the hydrophilic urinary catheter, and the reservoir receiving the hydrophilic urinary catheter wetting fluid has a closed position to be moved to an open position which is forward allows, under specified conditions, the wetting fluid to flow out of the wetting fluid reservoir, wherein the wetting container is provided with an inlet, ·· · · · · · · · · · · · · · ·

A typical sterilizing agent used to sterilize the wetting device of the present invention is ethylene oxide. Otherwise, the liquid in the liquid container is normally sterile. For this reason, the wetting fluid reservoir is preferably made of a material that is completely, but at least substantially impermeable to, the ethylene oxide and the liquid in the container. Non-limiting examples of materials satisfying these conditions include liquid water or saline, aluminum foil, polyvinylidene chloride or metal-coated film such as metal-coated polyethylene terephthalate.

In a further embodiment of the invention, which will be described, the wetting fluid reservoir can be combined with the wetting container in the operating position, namely the friction fit path between the wetting fluid tank and the wetting tank inlet.

According to a third aspect of the present invention, there is provided a wetting fluid container for use in combination with a wetting device having an inlet and a liquid receiving area in fluid communication with the inlet where said liquid container has a front portion which can be inserted into the device inlet, and includes an outlet that extends forward when a specified condition is applied, it can be moved from a closed position - when the liquid is retained in the fluid reservoir - to an open position when the liquid is in the liquid state.

the predetermined condition can be applied to the outlet when the front portion of the liquid container is inserted into the inlet, allowing fluid in the liquid container to escape into the fluid receiving area of the device. The fluid reservoir therefore reduces the problem of spillage of its contents into the fluid intake area.

Fig. 7 corresponds to the wetting device shown in Fig. 2, but the bag containing the wetting fluid is open; you • ·

Figure 8 is a graph of Figure 3, but the moisture-containing bag is open.

Referring now to Figure 1, a wetting device 10 according to the present invention is provided which includes a urine collection bag of transparent flexible plastic. This bag 1 terminates at the front end in an elongated pocket 2, which has sufficient depth to accommodate at least the insertion length of the hydrophilic urinary tract. The urine collection bag 1 contains 12 urine collecting chambers at the back of the pocket 2, which is in fluid communication with the 2 pockets. Further, there is an inlet 14 for the urine collection bag 1 through which the hydrophilic urinary catheter 3 can be inserted into the bag.

As can be seen, the urinary catheter 3 has a rearwardly extending portion 16 and an elongated stem 18 extending forward from the portion 16 and ending at a rounded tip 4 at its front end. The urinary catheter 3 has a non-depicted inner world extending from the open end in the portion 16 to the drainage opening 5 at the tip 4.

The container in the form of a bag 6 is attached to the inner surface of the urine collection bag 1. The bag 6 contains sterile water, saline or other liquid suitable for wetting the hydrophilic urinary catheter 3 and can be pierced or otherwise opened, for example, by hand pressure, so that practically all the water or saline contained therein is discharged in the pocket 2 directly into the pocket. before using the catheter.

Typically, the urine collection bag 1 is combined with the combined 6 • · · · · · and, if pre-packaged with the catheter 3, sterilized using ethylene oxide. Since the bag 6 contains sterile water or saline, there is no need to sterilize the contents of the bag.

Accordingly, the material of the bag 6 is preferably impermeable to ethylene oxide and water. Non-limiting examples of materials meeting these requirements are poly (vinylidene chloride) (PVDC), aluminum foil laminates and metal-coated films, such as metal-coated poly (ethylene terephthalate). Of course, other sterilization methods can be used, such as irradiation, in which case the liquid in the bag 6 can be sterilized on site, simultaneously with the other components of the wetting device 10.

The volume of the bag 6 is large enough to release an amount of water or saline in the pocket 2 capable of wetting the insert length of the urinary catheter 3 before use. The insertion length of the elongated stem 18 is at least the length of the insertion of a hydrophilic material, such as PVP, and inserted into the urethra of the patient. It is typically 80 to 140 mm for female patients and 200 to 350 mm for male patients.

The retention time of the catheter 3 in the pocket 2 may vary over a wide range, but typically at least 30 seconds.

The insertion of the bag 6 into the urine collection bag 1 is not critical until the bag 6 releases its contents in the pocket 2. However, it is recommended that the bag 6 be as close to the open end of the pocket as possible. In this embodiment, the bag 6 is permanently secured in the urine collection bag 1, for example by gluing to the bag 1. However, it can be seen that the bag 6 is in fact freely movable in the bag. The basic thing is that the bag 6 is within the boundaries of the bag 1 so that the two components form an integrated unit.

When used, the urinary catheter 3 is introduced into the urine collection bag 1 through the inlet 14 and the elongated stem 18 is guided into the pocket 2 as shown. The inlet 14 is then sealed, for example, by connecting a knot from the material of the inlet 14, or by connecting the input 14 with a clip. The bag 6 is then opened, for example, by applying pressure through the material of the urine collection bag 1 to release the wetting fluid into the pocket 2 and allowing the urinary catheter 3 to be soaked in the wetting fluid for a predetermined time to wet its hydrophilic outer surface.

Alternatively, the urine collection bag 1 may be provided with a closed end at the inlet site with a pre-packed catheter 3 in the bag. However, an inlet 14 is preferred when the sterilizing agent is ethylene oxide as it provides a flow path for the ethylene oxide to enter and exit the bag.

After the catheter 3 has been moistened for a predetermined period of time, the bag 1 is turned downward with the upper side and the front part of the pocket 2 is peeled off. The elongate stem 18 of the catheter 3 is passed through the opening at the front end of the pocket 2 and inserted into the urethra of the patient until the rearwardly extending portion 16 is mechanically sealed with the opening. Therefore, it is not necessary to directly grip the catheter 3 to introduce it into the urethra, which is advantageous because the outer surface of the catheter 3 • · · · ···· · ·· · ··· ·· · ····· · · · Ik · · · ··· ·· ··· ·· becomes slippery during the wetting process and is therefore difficult to grasp, and since the possibility of catheter 3 contamination at this stage is eliminated.

The urine in the bladder of the patient is transported backwards through the interior of the catheter 3 into the urine collection chamber 12. The catheter 3 is moved backward within the lumps of the bag 1 and the opening of the pocket 2 is closed, for example, by knotting the pocket material 2, or by clamping the pocket 2 through a clip. An aperture can then be made in the urine collection chamber 12 so that the collected urine can be poured out, after which the bag 1 is again available.

Referring to Figures 2 and 3, there is shown an alternative wetting device 110 according to the invention. This wetting device 110 includes a urine collection bag 101 of transparent flexible plastic material corresponding to the urine collection bag 1 of the wetting device 10, as described with reference to Figure 1. That is, the urine collection bag 101 has a downwardly extending elongated pocket 102 at its front end, above which the elongated pocket 102 has a fluid-associated urine collecting chamber 112, and has an inlet 114 for the bag 101 further disposed.

Also, as with the wetting device 10 described in connection with FIG. 1, there is a hydrophilic urinary catheter 103 with a widening back portion 116, an elongated stem 118 extending forward from the rear portion 116 and having an open end (not shown) inward 116 is formed at the rear end of the catheter 103 at the rear end of the rear portion

It extends up to 105 drain holes; the catheter 103 can be inserted into the urine collection bag 101 through the inlet 114, so that the insert length of at least the catheter 103 is preferably inserted into the pocket 102.

As can be seen in more detail in FIG. 3, a bag of wetting fluid 106 is inserted into the inlet 114 in the operating position when it is held in place by the friction fit. The bag 106 has a front portion 120 extending into the inlet 114 in the operating position of the bag 106, and a rear portion 122 extending rearwardly from the inlet 114 in the operating position.

The bag 106 is preferably made of aluminum foil, in particular when ethylene oxide is used to sterilize device 110, and

106 bags contain sterile water or saline. When ethylene oxide is used as the sterilizing agent for the device 110, the fit of the bag 106 to the inlet 114 is not so sealing as to prevent the ethylene oxide from entering and leaving the bag 101, thereby sterilizing the bag 101 and the catheter 103. internal and external surfaces. The wetting fluid is held in the bag 106 by sealing the circumferential seal of this bag, as shown in the figure.

Referring to Figures 4 and 5, it is seen that the front portion 120 of the bag 106 forms an edge 124. This front edge 124 has a tear line 126 at the back. On the front edge 124 of the bag 106, a first tab 128 is formed on one side of the tear line 126. On the other side of the tear line 126, there is an elongated second tab 130, in the extended position shown, wherein said second tab 130 extends from the front edge 124.

• ·· ·· · ·· · · · «« ··· · ···· · · · · · ···· · · · · · · ·

As shown in FIG. 6, the elongated second tab 130 is movable about the forward edge 124 from its extended position shown in FIGS. 4 and 5 to a retracted position in which the second tab 130 extends rearwardly from the first edge 124. If the second tab 130 is in this retracted position, the bag 106 may be inserted into the inlet 114 for the operating position shown in FIGS.

Referring now to Figures 2 and 3, the dimensions of the second tab 130 are such that when the bag 106 is in the operating position, the tension portion 132 of the second tab 130 extends rearwardly from the inlet 114 of the urine collection bag 101, and the bag 122 is rearward 122 a part of its part.

Figures 7 and 8 illustrate the operation of the bag 106 when its contents are allowed in the pocket 102 to moisten the hydrophilic outer coating of the catheter 103. The user of the device grabs the first tab 128 through the transparent flexible plastic of the urine collection bag 101, and then pushes backwardly the pull tab portion 132 of the second tab 130 extending from the inlet 114 to induce tearing along the tear line 126 and the wetting fluid therethrough. allows the pocket 102 to wet the catheter 103. Preferably, the bag 106 comprises sufficient wetting fluid to fill the pocket 102 to a level that will cause the catheter 103 to be inserted.

After allowing the wetting fluid to enter into the pocket 102, the catheter 103 may be used as described above for the wetting device 10 shown in Figure 1.

If necessary, the bag 101 may be sealed when

bag 106 and catheter 103 are prepackaged in this bag 101. In this case, the bag 101 is formed so that the bag 106 can be opened as described above, through the bag material.

The wetting device 110, as previously described in FIG. Figures 1 to 4 are advantageous since it is environmentally friendly in the sense that if the bag 106 is made of aluminum foil, it can be placed separately from the bag 101 to facilitate recycling of the aluminum foil and the bag 106 is more resistant to cyclic pressure. , which is typically to be applied to the wetting device when packaged and subjected to a sterilization process, which is due to the fact that the bag 106 may not be opened directly by the pressure exerted on the bag material 101, in which case a substantially thinned bag edge is required because it is not possible to apply high pressure through the bag 101 without the bag 101 being damaged.

Exemplified above in connection with the drawings. In embodiments, the wetting fluid supply for wetting the hydrophilic urinary catheter is in the form of a separate bag which is combined with the wetting agent container. It will be appreciated by those skilled in the art that the wetting fluid supply may also be a chamber combined with the wetting container material, without departing from the inventive idea.
