Catheter anchor system and method thereof
A method and system of and for securing a lumen or catheter, after placement in a patient, to prevent unwanted removal or dislodgement of the lumen or catheter caused by patient movement and/or further medical interventions such as cardiopulmonary chest compressions, electrical defibrillation, surgical procedures, and the like. The method and system comprising simple and sterile materials that preclude the use of excessive suturing and ineffective ad-hoc methods with tape and gauze. The catheter is secured by a rubber on plastic frictional force and will resist external forces while preventing the tube structure from bending and subsequent occlusion. The device can be comfortably attached to the patient in all of the anatomical locations typically targeted for large catheter installment. The method of securement is rapid and requires only a single personnel to handle the device and the catheter tube simultaneously.
1. An apparatus for securing a medical device to a patient during a medical procedure, the apparatus comprising:
a base having a top portion, a bottom portion, and an aperture located on the bottom portion, and wherein the base is configured to be affixed to a patient via the bottom portion; and
a medical device securing assembly configured to be secured within the aperture in the base,
the medical device securing assembly comprising a substantially cubic enclosure, a pair of closable doors, and a retention pad secured to an underside of each of the pair of closable doors, and wherein
the medical device securing assembly is further configured to attach the medical device to the base to hold the medical device in place during the medical procedure,
wherein approximately ⅓ of the bottom portion of the base includes micro-suction adhesive material with a seating hole for the medical device, and
wherein the bottom portion of the base is configured to be secured to the patient via an adhesive pad, the adhesive pad occupying approximately ⅔ of a surface area of the bottom portion of the base.
2. The apparatus of claim 1 , wherein the adhesive pad comprises via adhesive, micro-suction, glue and combinations thereof.
3. The apparatus of claim 1 , wherein the medical device is selected from a group consisting of a needle decompression catheter for chest decompression, a central venous catheter, Turkel catheter, Tenckhoff catheter, Hemodialysis catheter, Hickman line, Groshong line, Quinton catheter, Huber needle, percutaneous endoscopic gastronomy feeding tube, peripherally inserted central catheter, intrauterine pressure catheter, pulmonary artery catheter, Swan-Ganz catheter, and suprapubic catheter.
4. The apparatus of claim 1 , wherein the medical device intended for insertion into the patient is pre-attached to the apparatus.
5. The apparatus of claim 1 , further comprising at least one clip ring and at least one adhesive strip attached to the base adjacent to the medical device securing assembly and extending away from the medical device securing assembly, the at least one clip able to support varying lengths of the medical device.
6. The apparatus of claim 5 , wherein the at least one clip ring is slidable on the at least one adhesive strip.
7. The apparatus of claim 1 , wherein the base is a rigid body or a flexible base.
8. The apparatus of claim 1 wherein the medical device securing assembly further comprises:
a plurality of nubs protruding from an inner surface of a base of the medical device securing assembly, each of the plurality of nubs imparting a force on the retention pad when the pair of closable doors are closed, causing the retention pads to frictionally engage the medical device.
9. The apparatus according to claim 1 , wherein the medical device securing assembly further comprises:
a pair of locking tabs located on each of the pair of closable doors; and
a pair of locking tab receptacles for each of the pair of locking tabs, the locking tab receptacles located on sides of the enclosure, each of the locking tab receptacles configured to accept a respective locking tab such that the closable doors are substantially locked in place.
10. The apparatus according to claim 1 wherein the medical device securing assembly further comprises:
a retention pad retaining ridge located on an inner surface of each of the pair of closable doors, the retention pad retaining ridges configured to hold the retention pads substantially in place.
11. The apparatus according to claim 10 , wherein
the retention pads are held in place on the inner surface of the pair of closable doors by one of glue and ultra-sonic welding.
12. The apparatus according to claim 1 wherein the medical device securing assembly further comprises:
an aperture located through a base of the enclosure such that the medical device can substantially readily pass through the medical device securing assembly.
13. The apparatus according to claim 1 , wherein the medical device securing assembly further comprises:
a pair of hinge receptacles located on two opposing walls of the enclosure; and
a pair of hinge protrusions located on opposing sides of the pair of closable doors, wherein
the hinge protrusions are configured to fit within respective hinge receptacles, wherein the pair of closable doors are detachable.
14. The apparatus of claim 1 , wherein the enclosure and retention pads are made from rubber, plastic, silicone, and combinations thereof.
15. The apparatus of claim 1 , wherein the apparatus is three dimensionally printed and thereby customized to conform to the patient.
16. A method for securing a medical device to a patient during a medical procedure, the method comprising the following steps:
providing an apparatus according to claim 1 ;
securing the base to a skin surface of a patient;
inserting the medical device into the patient through the aperture in the base and the medical device securing assembly; and
closing the pair of closable doors such that the medical device is attached to the base.
17. The method of claim 16 , wherein the adhesive pad comprises adhesive, micro-suction, glue and combinations thereof.
