Claims.
My invention relates to improvements in kidney catheters. The object is to provide a new two- Way catheter that will make it possible to put a medical solution directly into the kidney without having it diluted with urine already in the oath eter. This invention consists of the construction and combination arrangements described herein and claimed. My invention is illustrated in the accompanying drawing forming a part of this application.
Fig. 1 is a longitudinal sectional view of the two-way catheter showing how the top of the catheter nearest the tip is separated into a chamber separated from the balance of the catheter by means of a wall or partition made into the catheter. It also shows how the hollow tube goes through this wall and empties the medical solution into the separate chamber.
Fig. 2 shows how the catheter can be assembled or taken apart.
The numeral l indicates a small aperture in the catheter C for draining the kidney of urine and any solution that may be injected into it.
The tip or head 2 of the catheter is made of soft rubber or any suitable material, and is pointed so it can be more easily inserted.
A round ball 3 is fastened on the end of the tube T by any suitable means, preferably by solder, its purpose being to prevent the tube from injuring the material of the catheter.
The tube T is cut as at 4 at approximately a forty-five degree angle at the ball end, so that the ball 3' can be fastened on the end and will still leave plenty of room for the solution to flow out of the tube.
A small aperture 5 is formed in the catheter 0 adjacent its outer end to allow the medical solution to flow out of the separate outer chamber in the catheter above the shoulder l and into the kidney.
A round flange 6 is secured around the hollow tube T, its purpose being to prevent the wire or tube from slipping down in or retracting from the catheter, same pressing against the walls of the outer chamber in the catheter.
An annular shoulder l is formed in the wall of the catheter to form the separate inner and outer chamber in the catheter, and providing a small hole just big enough to push the hollow tube '1 therethrough. This shoulder l compels the solution that comes through the tube to flow out into the kidney through hole 5.
Another aperture 8 is formed in the catheter opposite the inner chamber for draining the kidney.
A small hole 9 is formed in the catheter where the hollow tube T comes out, the catheter being thicker at this point to prevent it from leaking around the tube.
A thin tongue in is provided adjacent hole 9 having a hole in it that hooks on a hook member 15 of the tube T to hold the catheter in a stretched position while it is being directed up into the kidney.
The urine and solution is drained from the kidney out of the end ll of the catheter.
A hypodermic needle I3 is connected to the tube T which preferably screws into the needle I3 as illustrated in Fig. 2. The medical solution is injected through the needle at the end l4 through the hollow tube T into the separate outer chamber of the catheter, by means of a syringe or other suitable means (not shown).
I claim:
1. A two-way kidney catheter comprising a tube of flexible resilient material having a closed pointed end and. having an internal annular shoulder in its bore adjacent said end; said tube having outlets in its side wall above and below said shoulder; a rigid tube extending through the flexible tube and making a fluid-tight fit Within said shoulder; an enlarged head on the tip of the rigid tube engaging the closed end of the flexible tube, said rigid tube having an outlet adjacent said head; means on the flexible and rigid tubes for maintaining the flexible tube stretched between the head and said means; and means for introducing a liquid into said rigid tube.
2. In a catheter as set forth in claim 1, said rigid tube passing out through an opening in the wall of the flexible tube at a bend thereof; and said maintaining means comprising a perforated tab on the wall of the flexible tube adjacent the opening receiving a lug on the rigid tube.
3. In a catheter as set forth in claim 1, said rigid tube being cut on a bevel adjacent the head; and said head comprising a ball secured to the tip of the bevel.
4. In a catheter as set forth in claim 1, an external flange on said rigid tube above the shoulder seating on said shoulder and contacting the side walls of the said flexible tube.
5. In a catheter as set forth in claim 1, the outer end of the rigid tube being threaded for attachment to said liquid introducing means.
6. A two-way kidney catheter comprising a tube of flexible resilient material having a closed pointed end and having an internal annular shoulder in its bore adjacent said end; said tube having outlets in its side wall above and below said shoulder; a rigid tube extending through the said flexible tube and making a fluid-tight fit within said shoulder; an enlarged head on the tip of the rigid tube engaging the end of the flexible tube; said rigidtube having an outlet adjacent said head; a hook on said rigid tube engaging an eye on the flexible tube when elongated to maintain the latter stretched between the headland hook-i and means for introducing a liquid into said rigid tube.
7. In a catheter as set forth in claim 6, said rigid tube passing out through an opening in the wall of the flexible tube at a bend thereof; and a perforated tab on the outer wall of the flexible tube adjacent the opening receiving the said hook.
8. In acatheter as set forth in claim 6, said rigid tube being out on a bevel adjacent the head; and said head comprising a ball secured to the tip of the bevel.
9. In a catheter as set forth in claim 6, an external flange on said rigid tube above the shoulder seating on said shoulder and contacting the side walls'of the said flexible tube. V
10; In a catheter as set forth in claim 6, the outer end of the rigid tube being threaded for attachment to said liquid introducing means.
