Description

FIXING WINGS ADJUSTA-BLES BACKGROUND OF THE INVENTION Field of the Invention The invention relates to intracutaneous catheters and very specifically to devices of a f-i nzarn-Len. or to fix the percutaneous catheters in a desired position in the body of a patient " Description of Related Art Percutaneous catheters are commonly used in medical applications to supply fluids from a patient's body. It is very common in the treatment of patients to use intravenous catheters to introduce certain fluids directly into the patients bloodstream. It is also common to use the catheter to divert the obstructed passage between the organs. For example, when the passage between a kidney and the bladder is blocked, accepted treatment can be provided by kidney catheterization to drain the urine. Generally, a catheter consists of a tube or soft cannula having an opening or lumen, which extends through the null. Placing a catheter usually involves inserting an introducer tube wrapped around a needle, the introducer sheath having an outer diameter slightly larger than the needle, the lens in the desired position, and then removing the needle. The catheter is then inserted into the patient through the introducer. In case of a ca ete ?? Intravenous fluid, the fluid flowed directly through the catheter to the vein in which the catheter is inserted. In the case of a urinary drainage catheter, urine is drained directly from the kidney to a dispensary. Since catheters have different uses, catheters also have different lengths. For intravenous catheters, for example, there are several diverse lengths of catheters including short intravenous catheters that are placed perothermally, for example, on the hand, midline catheters of which are inserted from about 15.24 to 20.82 crn into a vein, For example, from the hand to the upper part of the arm where the vein is larger and the blood supply and blood flow is better, and central venous catheters of significant length that can be placed peripherally, ie, in the arm, and introduced, for example, to the superior vena cava. Regardless of length, it is desired to fix the catheter so that it maintains its position in the body. The placement of the catheter in the patient's body is important, particularly, the determination of the concentration and toxicity of the fluid added to the body. To ensure that the catheter maintains its position, the catheter should be secured to the outer body of a patient and ideally secured as closely as possible to the site or the catheter inlet junction to provide less opportunity for the catheter to be reattached. The common securing devices include wings for fastening with tape or with a lock, fixedly attached to the catheter cannula. The clamping wings with fixed position catheter locks works well if the full length of the catheter cannula is placed on the patient so that the wings are fixed at the joint. A problem arises, however, when the decision is made to shorten the placement of the catheter in the patient so that excess material from the catheter separates the clamping wings with t abas from the site to the insertion junction. If the wings are secured to the patient in a position that is too far away from the insertion, the position change or the piston-like movement of the catheter can occur. One way to avoid this is to cut the catheter tube to the proper length before inserting the catheter into the body. Since most catheters include a cap at their distal end, the only convenient end for trimming * is the inverse end. However, the catheter cannulas are generally constructed with a tapered tip at the introductory end to make the nose easier., that is, less traumatic, the insertion to the patient. If the tapered tip is removed, for example by cutting the catheter section, such considerations of the phantom are ignored. In addition, if the cut-off estimate proves to be incorrect, the doctor or nurse still has material in excess of the catheter cannula with which it should be treated. Another way of dealing with the excess material of the cannula extending from the junction, whether the catheter has been shortened or not, is to roll excess material from the catheter cannula around the fixation wings before the catheters are fixed. wings to the patient. This method allows the fixation device to be attached to the joint, but creates a stupid and voluminous device. Adjustable securing devices have been introduced that allow the device to be placed at the catheter junction once the catheter is placed. However, these diameters are either voluminous or difficult to effectively install at the site of attachment. An adjustable securing device is a two-piece device in which a first flexible part with a groove along its lower portion fits over the cannula adjacent to the joint and a second rigid part is press fit onto the first part. to compress the first piece to the cannula so that the catheter device can not move. Then, the entire device is sutured or taped to the skin. A problem with that type of device is that it is a two-piece device that must be dimensioned and fitted over the catheter cannula at the junction. The placement of the fixation device must be done artificially so that the patient is not bothered or the different parts are lost. Ademan, the second rigid piece makes the device bulky. Another type of adjustable fastening device is to compress a two-piece pressure-adjustable fastening device with an opening. This device uses at least one cylindrical opening that fits around the catheter and within a two-piece clamping device, mounted on a catheter cannula. When the clamping device is joined with force, the opening is compressed to produce frictional pressure to the catheter. This fixing device involves at least three pieces that can easily be placed incorrectly and it is difficult to manipulate and install the fastening device in the joint. What is needed is an adjustable locking device that is easy to install in a patient's unit and that is not bulky and difficult to handle.

DETAILED DESCRIPTION OF THE INVENTION The invention relates to an adjustable securing device for retaining a catheter-in a desired position within a patient. The invention is described below with reference to the following drawings. In the following description, numerous specific details are set forth such as materials, configurations and specific types of catheter. It will be obvious, however, to one skilled in the art that these specific details do not need to be used to practice the invention. In other cases, well-known materials or methods have not been described in detail to avoid unnecessarily obscuring the invention. Figures 1-8 illustrate a fashion of the invention securing device. Figure 1 illustrates the device. of the Invention of the Invention to Attach an Intravenous Catheter The Laity Mode shown in Figures 1-0, however, could be used with any type of catheter, including, but not limited to, catheters in avenues, ncurological catheters and urinary drainage catheters The invention relates to a securement device for holding a catheter in a desired position within a patient. In the example of the illustrated ravenous catheter or FIG. catheter 100 in the arm 150 of the patient to a vein in the same »Once the cannula 100 of the catheter is inserted with the desired length inside the patient, the fianzamiento device of the invention is placed directly next to the umon to say, the insertion site). The securing device of the invention includes a fixation member 110. The rotating member 110 has a tibular body portion with an opening extending through the tubular body. The aperture of the fixation member 110 has an imensloned diameter for retaining the catheter can LOO by locking the catheter cannula 100 such that the IOL fixation member is not movable around * the catheter cannula 110. This is best illustrated in the perspective view of the catheter. Figure 3 which illustrates the fixation member 110 locked by friction to the LOO catheter cannula. The diameter of the opening of the fixation member 110 may also become slightly smaller than the catheter cannula 100 even if a compressive force is applied to the cannula 100, in addition to the frictional force. L0 fixation member is appropriately placed in a desired position, the portions provided with wings of the fixation member 110 can become saturated or adhere with the patient's skin » Figures 1 and 2 illustrate a securing device with a fixation member 110 located in a position adjacent to the catheter cap 120. To position the fixation member 110, the securing device of the invention includes a member dilator 140. The dilator means 140 can move freely around the catheter cannula 100. In other words, the dilator member 140 has an aperture with a larger diameter than the catheter cannula 100. The dilator member 140 is adapted to be connected with the IOL fixation member through a tibular body portion of fixation member The F i gui 4 illustrates a perspective view of a securing device of the invention around a catheter cannula 100 »The Figure 4 shows a fixation member 110 with an opening that has been dilated by a dilator member 140 so that the fixation member 110 does not frictionally lock with the cannula. of Catheter 100. Instead, the entire splice of the securing device, including the portion of the dilator member 140 and the member portion 110, collectively defines an opening of sufficient diameter to move the securing diameter around the catheter cannula 100. The dilator member 14U has a notch or slot 14 that is extends over its length to allow the dilator member 140 to be divided into two pieces to facilitate its removal from the catheter once the fixation member 110 is in place. Figure 5 illustrates a top view in cross section of the securing device. The invention is shown along lines IA-A of FIG. 4. FIG. 5 shows a portion of miernbi or dilator 140 that includes a portion of a tubular body that has an opening extending through the body. the body portion and diameter of the opening is larger than the outside diameter of the catheter cannula 100. FIG. - illustrates a side perspective view of the dilator member 140 of the invention. The dilator member 140 includes a substantially tubular body portion with an aperture extending along the portion of the body. The body portion is made of a durable material or plastics such as pol luret not, polyethylene, TEFLON® (produced by * The »DuPont of Nemours and Company, Utimington, Delaware), polypropylene, and polyvinyl chloride" The body portion of the embodiment illustrated in Figure 6, includes a portion tapered 145 for facilitating insertion and splicing with fastening member 110 »Dilator member 140 further includes a reduced wall thickness section with a notched section 147 (vgr., notched with a razor blade) ) on opposite sides of the dilated member! * 140. The reduced portions of thicker allow the limb member to be divided into two pieces to remove the dilator member 140 from the catheter once the fixation member 110 is in place . Figure 7 illustrates a cross-sectional view of the adjustable securing device of the invention taken along the line BB of Figure 5 »In Figure 7, the securing device includes a fixing member 110 with a large aperture by the dilator member 140 to widen the opening of the securing device such that the securing device can move freely around the catheter cannula 100 and can be adjusted in any desired position. Once the casting device, including the Latderating means 140 and the fastening means 110, is positioned in the desired position around the catheter and in relation to the patient's body, the position of the dilating means 140 Was it removed and l? The position of the tubular body of the fixation means 110 adopts a diameter that is frictionally locked with the catheter cannula 100. The opening of the tubular body position of the fixation means 110 is directed to lock with friction with the cannula. of catheter 100 so that the fixation member 110 is not movable around the LOO cannula. In this way, the catheter cannulas of various sizes will have securing devices, including fixation means with body portions of various diameters to lock onto the catheters by friction grip force. The invention also contemplates that the The opening in the tubular body portion can be sized slightly smaller than the outside diameter of 1 A catheter cannula 100. In this way, the fixation means 110 becomes compressive locking as well as friction! with the cannula 100. An important property of the fixation member 110 is that it is extensible and that it will return to its memorized diameter, appropriately directed, once the dilator member 140 is removed. Suitable elastomeric materials to build the body portion tubular * of the fixation member that is dilatable but returns, in its undilated state, to be locked in a functional or nonfunctional manner and compressively with the catheter include, but not limited to, polyurethane, polyethylene, chloride, polyvinyl chloride , "MOUSE * (produced by Shell Oil Cornpany, Houston, Texas), isoprene, SANTOPRENE" (produced by Monsanto Company, S "Lo? Is, Mi souri), and HYTREL-R i" produced by DuPont de Nemours, Wi lnington, Delaware). Figures 8 and 9 illustrate the removal of the dilator member 140 from the fixation member 110 once the fixation member 110 is placed in the desired position on the catheter 100. Figure 8 demonstrates that the fixation member 110 or firmly in place with the lance and? o? other means, including sulphures, tape, etc., and the dilator member 140 is advanced far away from the IOL fixation member. Once the dilator member 140 is away. of the fixing member 110, the fixing member 110 is frictionally engaged or rubbed! and compressively with the LOO null »Also, while pulling on dilated limb * 140 away from the IOL fixation member, the dilating member is divided and moved away from the catheter» As indicated above, the coins in the dilator They can easily be divided into carving or spitting the opposite side walls or constructing the portion of the dilator member 140 with opposite sides of reduced wall thickness., the division occurring along the portions 147 with reduced wall thickness, and then separating the walls by hand pulling. Figures 8 and 9 describe an embodiment in which the dilator member 140 is removed from the catheter once the fixation member 110 is properly positioned. The invention also contemplates that the same dilator can remain on the catheter and be used for the reinforcement of the catheter. catheter or twisting resistance, or the like »Figures 10 and 11 illustrate different embodiments for the portion of the fixing member of the securing means of the invention» Figure 10 illustrates fixing means 200 including a portion of tubular body 210 that is bent. The curvature of the tubular body portion 210 of the fixation means 200 provides additional grip support to firmly hold the catheter cannula and also guide the catheter to a different direction from the direction in which it enters the catheter to the fixation member 110. The invention contemplates that a dilated member is configured in a manner to dilate, if necessary, the entire bent body portion 210 of the fastening member 200. Sirily, Figure 11 illustrates a mode of the fastening device with a member. of fixation 250 q and includes a portion of tubular body 260 that is completely bent ,. This allows an intravenous catheter, for example, to penetrate a patient at an angle of 180 ° with respect to the direction of the intravenous inflow duct, Also, the invention contemplates that, if necessary, a portion of the dilated limb * The entire bent body portion 260 of the fastening member 250 will be dilated. Figure 12 illustrates another embodiment of the fastening member portion of the invention. FIG. 12 depicts a do-fixation member 300 with a p <.In this embodiment, in order to dilate the fixation member 300, a portion of the dilator member must dilate each fixation 310. FIGS. and 14 illustrate other embodiments of the "fixation member" of the invention. Figures 13 and 14 present portions of the fastening member in which the fastening member is a tubular section or sections. The fixation member 320 of Figure 13 includes an arcuate or arcuate shaped body 330 which is locked with a catheter cannula. The opening in the arch portion 330 was frictionally rubbed! Fig. 14 illustrates fastening member 340 which includes a multitude of, in this case, 3, arcuate configuration portions 350 each of which is extensible and which lock fp. ccionalmente or fricciona! and compressively with the catheter cannula, Figure 15 illustrates a second solenoid of the dilator member portion of the securing device of the invention. In Figure 15, the dilator member 360 has a cleft collar 370 to facilitate the division of the dilated member! - 360. In Figure 15, the opposite wings of the collar portion 370 are pulled apart while the dilated member! 360 is separated from the member of? fixation.

The invention contemplates that the fixation member and optionally the dilated member! - are prearranged on the catheter body. The preloading modality is parculularly useful in cases where the opening or the openings in the fixation member portion of the catheter body. They are dimensioned slightly smaller than the catheter cannula *. The preloading mode also eliminates the possible misplacement of the components of the securing device and facilitates the simple installation of the securing device. Of course, the invention also contemplates an augmentation device which is not pre-loaded, but which is installed on the catheter once the catheter is placed in a patient. Furthermore, since the dilator member is removed once the fixation member is in place, the securing device of the invention is not bulky or difficult to handle. As stated above, the invention's affixation system could be used to fix any catheter. Figures 16-20 illustrate the securing device for use with a catheter over the needle. A catheter on the needle generally consists of a needle coupled to an extended stylet and a catheter cannula that extends over the needle and along the stylet. In a catheter over the needle, the needle and catheter tube are placed simultaneously, allowing the use of a smaller needle size, eg, 3-4 smaller measurements, than a catheter of the type through the introducer in which the catheter must enter through the opening created by the needle. In the design of a catheter over the needle, the outside diameter of the catheter * is larger than the opening made by the needle, thus allowing a catheter of similar diameter to be inserted with a smaller needle. A problem associated with catheters over the needle is that it can be difficult to insert both the needle and the catheter cannula at the same time. Since the catheter moves freely over the needle and the stylet, when the needle is inserted, the catheter can buckle or oppose the entrance. One way to overcome this problem is through the use of rotating wing clamps that hug or squeeze the catheter and the needle when the wings are folded together. Figures 16 and 17 illustrate an embodiment of the invention in which the fixing means 410 includes wings of formal > which, when compressed or bent, embrace or tighten the catheter and the needle or the stylet »Figure 16 illustrates the fixation means 410 with the wings in a downward or unfolded position» Figure 17 illustrates the medium of fixation 410 with the wings in bent position with engagement on the catheter-cannula 400 and the needle 440 coupled to the stylet 450. The securing device of this mode works in a manner similar to that described above with reference to Figures 1-15 including a portion of fixing means 410 and a dilator member 420 to dilate the body portion of the fixing member 4LO. This fashion L idad adds the additional feature that the wings are formal: -s in such a way that the fixation member 410 can also embrace, applying additional compressive force, catheter / acu cannula while the cannula and the cannula are placed. needle in a patient. The window 430 illustrates that the cannula and the needle are compressed by the fixation device when the wings are folded 410 to impart additional compressive force. In the unfolded state, an undilated fixing member 410 is fixedly locked with the cannula 400 as described above. Figure 18-20 illustrates a further aspect of the invention, particularly useful with catheters on the needle. The dilator member 520 is forcefully inserted into the fixation member 510 and dilates the tubular body portion of the fixation means. 510 as described above with reference to Figures 4-8 and the accompanying text. The limb member extends further beyond the fixation member 510 and the skin / body of the patient as shown in Figure 19., the dilator member 520 acts as an introducer allowing a smoother transition to place the catheter cannula, for example, the catheter on the needle, clearing the conduit and removing any slag from the skin. Figure 20 illustrates that once the catheter is properly positioned, the dilator member 520 can be removed from the skin / body and the fixation member 510 and, optionally, removed from the catheter-abatement by division. In the foregoing detailed description, the invention is described with reference to the specific exemplary embodiments thereof. It will be clear, however, that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. as set forth in the claims. The speci fi cation and the drawings, according to the foregoing, should be considered in an illustrative sense as restrictive,
