Dialysis connector and cap having an integral disinfectant

Abstract

Apparatuses and methods for providing sterile connection during, for example, dialysis therapy. The present invention provides a connector and a cap therefore that easily and readily attaches to a dialysate container and a catheter inserted into a patient's peritoneal cavity. The connector and the cap enable the dialysate to readily transport between the container and the peritoneal cavity while minimizing the potential of contamination therein due to, for example, handling during use. The connector includes a shell that encloses a cap. The cap houses a slit septum and also includes a sealed disinfectant within an interior receptacle. When the catheter or catheter set attaches to the cap, the seal breaks and the disinfectant spreads over the threads between the catheter set and the cap.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates generally to medical treatments. More specifically, the present invention relates to medical connectors for use in medical treatments, such as Peritoneal Dialysis (“PD”). [0002] Due to disease, insult or other causes, a person's renal system can fail. In renal failure of any cause, there are several physiological derangements. The balance of water, minerals and the excretion of daily metabolic load is no longer possible in renal failure. During renal failure, toxic end products of nitrogen metabolism (urea, creatinine, uric acid, and others) can accumulate in blood and tissues. [0003] Kidney failure and reduced kidney function have been treated with dialysis. Dialysis removes waste, toxins and excess water from the body that would otherwise have been removed by normal functioning kidneys. Dialysis treatment for replacement of kidney functions is critical to many people because the treatment is life saving. One who has ...

Benefits of technology

[0046] It is therefore an advantage of the present invention to provide a dialysis connector that eliminates the need for the use and therefore handling of an additional cap to seal a catheter subsequent to use.

[0047] Moreover, an advantage of the present invention is to provide a dialysis connector that reduces the likelihood of peritonitis.

[0048] Another advantage of the present invention is to provide a dialysis cap that remains attached to a catheter set after use.

[0049] Still another advantage of the present invention is to provide a connector and a cap therefore having a septum that automatically reseals upon removal of the cap from a shell that couples to the dialysate container.

[0050] A further advantage of the present invention is to provide a dialysis connector employing a sealed disinfectant in conjunction with a releasable and resealable cap, which effectively minimizes the spread of microbial contamination to a catheter transfer set, and thus to the patient, during dialysis therapy.

[0051] Yet another advantage of the present invention is to provide a cap for use in PD, including CAPD and APD that contains a disinfectant and that cannot spill the disinfectant when a tip protector is removed.

Problems solved by technology

Due to disease, insult or other causes, a person's renal system can fail.

The balance of water, minerals and the excretion of daily metabolic load is no longer possible in renal failure.

During renal failure, toxic end products of nitrogen metabolism (urea, creatinine, uric acid, and others) can accumulate in blood and tissues.

A frequent problem that occurs with PD is peritoneal infection or peritonitis which can readily occur given the repeated disconnecting and reattaching of the dialysate containers.

Peritonitis can be painful and can temporarily diminish the hydraulic permeability of the peritoneal membrane, rendering the renal treatment less successful.

These methods however are messy, time consuming, effort consuming, inconsistent and may be subject to overkill in order to achieve consistently effective results.

However, the spread of contamination can still occur due to, for example, a cut in the glove or other like condition.
