Catheter securement device and related methods

Abstract

A catheter securement device includes a body having a generally curved channel configured to receive a central venous catheter and reposition it in a different direction than the direction of the catheter as it exits the skin of the patient. The securement device includes a cover that slidably connects to the securement device body to prevent the catheter from being pulled out of the curved channel.

What is claimed is: 
     
         1 . A catheter clamp for use in securing a central venous catheter in a vein, comprising:
 a catheter clamp body defining a curved channel extending between a first end and a second end thereof, the curved channel having an opening and a diameter configured to accommodate a tubing of a central venous catheter having a size in a range from 2 French to 8 French, wherein the catheter clamp body has a surface that contacts the skin of a patient and is shaped to orient a free end of the tubing away from a direction of catheter insertion and to support a bent profile of the tubing with an angle in a range between 90° to 210° in a same plane as the surface that contacts the skin of the patient, thereby reducing the risk of kinking the tubing;   an adhesive or one or more eyelets, or both, coupled to the catheter clamp body for affixing the catheter clamp to the skin of the patient; and   a cover that slidably connects to the catheter clamp body and covers the opening to the channel, thereby securing the catheter in the channel.   
     
     
         2 . The catheter clamp of  claim 1 , wherein the cover and the base slide together in a direction transverse to the direction of the opening for inserting the catheter in the channel. 
     
     
         3 . The catheter clamp of  claim 2 , wherein the body includes extensions that form undercuts and the cover includes flanges that slidably engage the extensions. 
     
     
         4 . The catheter clamp of  claim 1 , wherein the curved channel has a radius of about 1.5 to about 5 cm. 
     
     
         5 . The catheter clamp of  claim 1 , wherein the channel is configured to hold the catheter within the channel, the catheter having a size in a range from 5 French to 7 French. 
     
     
         6 . The catheter clamp of  claim 1 , wherein the curved channel is configured to accommodate a catheter within the channel, the catheter having a size in a range from 7 French to 9 French. 
     
     
         7 . The catheter clamp of  claim 1 , wherein the catheter clamp body is pliable and the cover is rigid. 
     
     
         8 . The catheter clamp of  claim 1 , further comprising an antimicrobial material. 
     
     
         9 . The catheter clamp of  claim 1 , further comprising at least one eyelet coupled to the catheter clamp body and/or the cover for affixing the catheter clamp to the skin. 
     
     
         10 . A kit, comprising:
 the central venous catheter as in  claim 1 ;   one or more components for inserting the central venous catheter into a vein of a patient; and   the catheter clamp of  claim 1 .   
     
     
         11 . The kit of  claim 10 , wherein the curved body defines a channel with a radius in a range from 1.5 to 5 cm. 
     
     
         12 . The kit of  claim 10 , wherein the central venous catheter is a multi lumen catheter. 
     
     
         13 . The kit of  claim 10 , wherein the one or more components for inserting the catheter includes one or more of a procedure tray, an anesthetic, a sterilizer for the patient's skin, a needle, a guide wire, a dilator, or a scalpel. 
     
     
         14 . The kit of  claim 10 , further comprising a suture needle and a length of suture. 
     
     
         15 . A method for securing a catheter to a patient's skin, the method comprising:
 positioning the central venous catheter as in  claim 1  in the superior vena cava of a patient;   positioning a free end of the central venous catheter in the catheter clamp of  claim 1 ; and   securing the catheter clamp to the patient's skin.   
     
     
         16 . The method of  claim 15 , wherein the catheter clamp is secured to the patient's skin with at least one suture or staple passing through at least one eyelet of the clamp and into the patient's skin. 
     
     
         17 . The method of  claim 15 , wherein the catheter and the catheter clamp are secured at the a jugular position. 
     
     
         18 . The method of  claim 15 , wherein the size of the catheter is in a range from 5 French to 7 French and wherein the curve of the curved body of the clamp prevents kinking of the catheter in the channel.
