Description

  Millions of people are suffering from intestinal autonomy. Failure to adjust the intestines can cause people to be hindered in behavior, unsanitary and socially isolated. There are a wide range of treatments for the condition, ranging from traditional treatments to radical treatments such as surgery. However, many patients do not get good results with traditional treatments, and for many reasons, few are willing to undergo surgery.

  The prior art is a device used to eliminate the damage suffered from bowel malfunction by controlling the condition to achieve a normal Lyle style. One such device is disclosed in US Pat. No. 4,831,422 (Fischer et al.). This device is a probe having a double lumen and an inflatable cuff. When the reflected IR light is transmitted and managed and a certain amount of reflected IR light is measured, an alarm signal is issued. The IR light is reflected in response to feces.

  Most intestinal control probes have electronics to detect the presence of stool and provide an alarm to avoid intestinal malformation. There is a need in the prior art for an expensive, single-use catheter that can be used to prevent bowel imbalance.

  The object of the present invention is to provide an inexpensive bowel catheter.

  Another object of the present invention is to provide a single-use catheter having the controllability of a one-way valve in the cuff around the catheter.

  Another object of the present invention is to provide a catheter that can be broken and removed to ensure only a single application.

  Another object of the present invention is to provide a catheter having a hydrophobic filter tip.

  Such objects, etc. of the present invention will become apparent to those skilled in the art upon reading the present disclosure.

  The single use catheter of the present invention has a lumen with a hydrophobic filter tip at one end. The lumen separates into two parallel conduits. The first conduit has an end at the one-way valve. A dropper is attached to the one-way valve. Air, saline or sterilized water can be introduced through the one-way valve to inflate the cuff around the lumen. The second parallel conduit has a charcoal filter at the end to eliminate intestinal gas. The one-way valve prevents the cuff from being deflated, so that the fluid exits the cuff and the cuff is deflated and the lumen is not cut.

  The present invention contemplates a novel catheter that overcomes the aforementioned problems and the like.

According to the present invention, the invention is as follows.
(1) a lumen having a first end and a second end; an inflatable cuff or fold around the lumen; the lumen having first and second conduits; A conduit is in fluid communication with the inflatable fold, the second conduit is in fluid communication with the first end of the lumen, and has an inlet at the end of the first conduit, at the inlet Provides a single-use catheter characterized by having a one-way valve.
(2) In addition, a syringe is attached to the inlet.
(3) Furthermore, a hydrophobic filter tip is provided at the first end of the lumen.
(4) Further, the second conduit has a charcoal filter.

(5) And a lumen having a first end and a second end; an inflatable cuff that surrounds the lumen, that is, a folded portion; and a first end of the lumen having a hydrophobic tip A single-use catheter is provided.
(6) It further has a charcoal filter in the lumen.
(7) a first conduit having a first end and a second end; a second conduit having a first end and a second end and parallel to the first conduit; An inflatable cuff surrounding the second conduit; the first conduit is in fluid communication with the inflatable flap and has a one-way valve at the second end of the first conduit A single-use catheter is provided.
(8) It has an inlet at the second end of the first conduit, and a syringe is attached to the inlet.

  Referring to FIG. 1, a single use catheter is formed by a lumen 20 having a parallel first conduit 22 and a second conduit 24. The lumen has a terminal end at the distal end of the hydrophobic filter tip 28. Apart from the filter tip 28, a cuff or fold 26 is provided surrounding the lumen 20. The cuff 26 is firmly connected to the lumen. The 1st conduit | pipe 22 is couple | bonded so that it may distribute | circulate smoothly with a cuff part. A conduit 22 extends from the cuff and terminates in a one-way valve 32.

  A dropper 52 having a tube 54 is coupled to the one-way valve 32. The dropper is preferably a valve or plunger type. The dropper is filled with 20-25 ml of physiological saline or sterilized water. After the tube is coupled to the one-way valve, the dropper is used to inflate the cuff as described below. The second conduit 24 extends from the hydrophobic tip 28 at one end to the filter 44 at the other end. The filter 44 is made of a charcoal filter sandwiched between two hydrophobic filters. The filter cap is used to close the second conduit 24.

  To use the catheter, the user grasps the lumen under the balloon. The lumen is inserted into the anus to about 3 inches or a depth recommended by the physician. Once a dropper is used to inject sterile water or saline through the first conduit 22, the cuff 26 is inflated. After inflating, remove from the one-way valve as it is no longer needed. Once inflated, the cuff is placed against the sphincter.

  The catheter is particularly useful for patients who are able to maintain normal discipline of bowel movement. At an approximate time according to the discipline felt by the user, the catheter can be moved to allow bowel movement. The one-way valve can discharge liquid from the cuff part in order to deflate the cuff part. In order to deflate the cuff, the user must cut the lumen so that the liquid in the cuff exits the first conduit 22. When deflated, the catheter can be removed.

  The tip of the lumen is preferably made of silicon and includes a hydrophobic filter. The hydrophobic filter provides a barrier to the liquid but can allow gas to pass through the second conduit 24. The second conduit 24 is provided with a charcoal filter 44, which can eliminate the odor of the gas that has passed through the catheter.

  The invention has been described with reference to the preferred embodiments. Variations and variations are possible for others as long as the detailed description is read and understood. It is intended that all such modifications and variations be included within the scope of the present invention, so long as they are within the scope of the claims and are equivalent thereto.

  It provides new ideas and devices to reduce various disorders resulting from intestinal malfunction.

It is a side view of the catheter of this invention.
