Abstract
An intravenous (IV) therapy system to facilitate the insertion of a catheter or another suitable IV device into a patient may include a band made of flexible material to be secured around a limb of a patient. The IV therapy system may include a window formed through the band to provide access to the patient's body. The IV therapy system may include a tourniquet formed within the band to selectively apply a pressure against the patient's body. The IV therapy system may include a blood vessel indicator to indicate where the catheter or other suitable IV device is to be inserted.
Claims18
A band to facilitate the insertion of a catheter into a patient, comprising:
- a sleeve made of flexible material, wherein the sleeve has a cylindrical shape and is configured to be secured around a limb of a patient;
- wherein an elongated window is formed in and through the flexible material of the sleeve to provide access to the limb of the patient through the sleeve, wherein the elongated window comprises a distal end and a proximal end, wherein a length of the elongated window between the distal end and the proximal end is greater than a width of the elongated window to follow a path of a blood vessel in the limb of the patient, wherein the flexible material in and through which the elongated window is formed is configured to apply pressure around the path of the blood vessel to cause the blood vessel to be more pronounced within the elongated window;
- a tourniquet formed within a portion of the flexible material of the sleeve to selectively apply a pressure against the limb of the patient, wherein the tourniquet comprises a bladder, wherein the bladder comprises an elongated strip having a width and a length longer than the width, wherein the portion of the flexible material of the sleeve in which the tourniquet is formed extends generally parallel to a longitudinal axis of the sleeve and generally parallel to the elongated window, wherein the bladder is configured to be sequentially inflated and deflated along the length of the bladder to thereby correspondingly and sequentially increase and decrease a pressure applied by the portion of the flexible material of the sleeve to the limb of the patient;
- and
- a blood vessel indicator to indicate where the catheter is to be inserted, wherein the blood vessel indicator comprises a near-infrared (near-IR) camera disposed within the elongated window to detect the blood vessel within the elongated window, wherein the near-infrared camera is disposed closer to a distal end of the elongated window than a proximal end of the elongated window to facilitate placement of the catheter proximal to the near-infrared camera.

A method of manufacturing a band for use in inserting a catheter into a patient, the method comprising:
- forming a sleeve of flexible material, wherein the sleeve has a cylindrical shape and is configured to be secured around a limb of a patient;
- forming an elongated window in and through the flexible material of the sleeve to provide access to the limb of the patient through the sleeve, wherein the elongated window comprises a distal end and a proximal end, wherein a length of the elongated window between the distal end and the proximal end is greater than a width of the elongated window to follow a path of a blood vessel in the limb of the patient, wherein the flexible material in and through which the elongated window is formed is configured to apply pressure around the path of the blood vessel to cause the blood vessel to be more pronounced within the elongated window;
- forming a tourniquet within a portion of the flexible material of the sleeve to selectively apply a pressure against the limb of the patient, wherein the tourniquet comprises a bladder, wherein the bladder comprises an elongated strip having a width and a length longer than the width, wherein the portion of the flexible material of the sleeve in which the tourniquet is formed extends generally parallel to a longitudinal axis of the sleeve and generally parallel to the elongated window, wherein the bladder is configured to be sequentially inflated and deflated along the length of the bladder to thereby correspondingly and sequentially increase and decrease a pressure applied by the portion of the flexible material of the sleeve to the limb of the patient;
- and
- integrating a blood vessel indicator into the flexible material of the sleeve to indicate where the catheter is to be inserted;
- and
- communicatively coupling the tourniquet to a processor to direct the application of pressure against the patient's body, wherein the bladder is configured to be sequentially inflated and deflated along the length of the bladder when the processor detects an activation signal generated in response to input from a clinician.

- wherein an elongated window is formed in and through the flexible material of the sleeve to provide access to the limb of the patient through the sleeve, wherein the elongated window comprises a distal end and a proximal end, wherein a length of the elongated window between the distal end and the proximal end is greater than a width of the elongated window to follow a path of a blood vessel in the limb of the patient, wherein the flexible material in and through which the elongated window is formed is configured to apply pressure around the path of the blood vessel to cause the blood vessel to be more pronounced within the elongated window;
- a tourniquet formed within a portion of the flexible material of the sleeve to selectively apply a pressure against the limb of the patient, wherein the tourniquet comprises a bladder, wherein the bladder comprises an elongated strip having a width and a length longer than the width, wherein the portion of the flexible material of the sleeve in which the tourniquet is formed extends generally parallel to a longitudinal axis of the sleeve and generally parallel to the elongated window, wherein the bladder is configured to be sequentially inflated and deflated along the length of the bladder to thereby correspondingly and sequentially increase and decrease a pressure applied by the portion of the flexible material of the sleeve to the limb of the patient;
- a processor integrated into the flexible material of the sleeve, the processor being configured to control the tourniquet;
- a blood vessel indicator to indicate where the catheter is to be inserted, wherein the blood vessel indicator comprises a near-infrared (near-IR) camera disposed within the elongated window to detect the blood vessel within the elongated window, wherein the near-infrared camera is disposed closer to a distal end of the elongated window than a proximal end of the elongated window to facilitate placement of the catheter proximal to the near-infrared camera;
- and
- an IV device insertion indicator integrated into the flexible material of the sleeve to indicate the insertion of the catheter into the blood vessel.
