METHOD OF USING A CATHETER WITH A DEDICATED FLUSHING PORT

Abstract

A method of using a catheter with an integral a dedicated flushing port system that allows the practitioner to irrigate an inserted catheter to remove blood dots and other substances from the patient without removing the drainage tube, thus greatly reducing the risk of infection. A holder keeps the flushing port clean and while not in use. A drainage bag with a large spout is provided to allow easy empting of the drainage bag. In one embodiment, the flushing port is integrated as part of the catheter. In another embodiment, the flushing port is part of the drainage tubing and in another embodiment, the flushing port is provided as an attachment piece that fits between the catheter and the drainage tubing. The drainage bag has a handle that allows the user to tip the bag to empty.

DETAILED DESCRIPTION OF THE INVENTION

[0020] In the following detailed description of the invention, reference is made to the drawings in which reference numerals refer to like elements, and which are intended to show by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and that structural changes may be made without departing from the scope and spirit of the invention.

[0021] FIG. 1 shows a prior art catheter system in a typical setup with a continuous bladder irrigation bag (CBI) 125 attached using an irrigation tubing 155 which is attached to an irrigation port 120 disposed on a catheter 110. A drip chamber 127 and roller clamp 128 is typically used to control the flow of the irrigant. A drainage tubing 150 is attached to a drainage port 130 on catheter 110. Drainage tubing 150 is attached to catheter 110 and a drainage bag 135 is used to collect the urine when properly inserted into the urinary track of a patient (not shown). During use, the catheter must be flushed to remove blood clots and other substances that can build up. In order to flush the system, drainage tubing 150 must be removed and carefully placed to keep it clean and sterile. An irrigation syringe 180 is used to flush the system with a sterile solution and a tray 185 is placed under drainage port 130 to catch the flushing fluids as they flush from the system. Great care must be used to keep from introducing any bacteria or infectious agents into the system during this procedure. Once flushed, drainage tubing 150 is reconnected until flushing is needed and the procedure is repeated. In general, flushing a prior art catheter is one of the most frequent sources of contamination and infection in the patient.

[0022] Referring to FIGS. 2-4, 7, 9-10 and 13-14, a catheter with dedicated flushing port system 100 is shown using 3-way catheter 110 has an end which is inserted in a patient (not shown) and held in place with an inflatable balloon portion 115 as is known in the art. Inflatable balloon portion 115 is inflated and deflated using a balloon fill port 160. In use, continuous bladder irrigation bag 125 is connected to irrigation port 120 to supply the irrigant using irrigation tubing 155 along with drip chamber 127 and roller clamp 128 as described above. A catheter drainage tube with dedicated flushing port 170 is connected to drainage port 130 on catheter 110. A dedicated flushing port 140 is provided to allow the user to flush catheter 110 without the necessity of disconnecting and then reconnecting catheter drainage tube with dedicated flushing port 170. A drainage bag 190 is connected using catheter drainage tubing with dedicated flushing port 170.

[0023] Drainage bag 190 has a sealable drainage spout 192 that is sealed using a hook and loop fastener 198. Sealable drainage port 192 is large enough to easily allow blood clots and other collected substances to be removed by opening sealable drainage spout 192 and tipping drainage bag 190 using a handle 195. Once drained, sealable drainage spout 192 is resealed. Of course other resealable means may be used to seal drainage bag 190 as long as sealable drainage spout 192 is resealable. A flushing port holder 145 allows dedicated flushing port 140 to be sanitarily stored while not in use. A clamp 165 is used to clamp off dedicated flushing port 140 when not in use.

[0024] When flushing is required, dedicated flushing port 140 is removed from holder 145 and irrigation syringe 180 is filled with irrigant solution such as a saline solution and then inserted in dedicated flushing port 140 where the irrigant is injected and then clamp 165 is used to clamp off dedicated flushing port 140. Of course other clamping means may be used to control the flow fluids as is known in the art. The flushing fluid irrigates the urinary track of the patient and then flows out through drainage port 130 and is directed down through catheter drainage tube with dedicated flushing port 170 and into drainage bag 135 without the need to open the system up, thus reducing the likelihood of external contamination and infection. The system may be flushed as needed by repeating the procedure. When flushing is complete, dedicated flushing port 140 is placed in holder 145 until needed.

[0025] Referring now to FIGS. 5 and 6, a catheter with integral dedicated flushing port 175 is shown having an elongated drainage port portion 133 with a dedicated flushing port 142 and a holder 147 to secure dedicated flushing port 142 when not in use. Again clamp 165 is used to control fluid flow. An irrigation port 122 and balloon fill port 162 are provided to be used as described above. FIG. 6 illustrates the non-use storage position with dedicated flushing port 142 retained in holder 147.

[0026] Now referring to FIG. 8, a flushing port attachment 112 is attached to catheter 110 using drainage port 130 and then drainage tubing 150 is attached to a drainage port 134 located on flushing port attachment 112. A dedicated flushing port 144 is provided to allow the user to flush the system without detaching drainage tubing 150 as described above. As discussed above, flushing port 144 is removed from a holder 148 which allows the user to flush the system without having to detach the drainage tube.

[0027] Referring to FIG. 11, a two-way catheter 102 is shown having a drainage port 131 and a balloon fill port 161. Catheter drainage tube with dedicated flushing port 170 is inserted in drainage port 131. As discussed above, flushing port 140 is removed from holder 145 and allows the user to flush the system without having to detach the drainage tube.

[0028] Now referring to FIG. 12, a one-way catheter 103 is shown having a drainage port 136. Flushing port attachment 112 is attached to catheter 103 using drainage port 134 and then drainage tubing 150 is attached to a drainage port 134 located on flushing port attachment 112. Dedicated flushing port 144 is provided to allow the user to flush the system without detaching drainage tubing 150 as described above.

[0029] Signs and Symptoms of a Blocked Catheter [0030] No urine flow from the catheter. [0031] Suprapubic distention and lower abdominal pain becoming more pronounced as the bladder fills. [0032] Urine leaking around the catheter (bypassing). [0033] Vaso-vagal symptoms may develop i.e, sweating, tachycardia and hypotension if the blockage is unrelieved.
