FIG. 1 shows anophthalmic infusion support 100 according to one example of the invention. Theophthalmic infusion support 100 includes abase unit 102 having abottom surface 104 and atop surface 106. In one example thebase unit 102 is substantially flat in one dimension (for example in the plane of the page ofFIG. 1 ). In such an example thebase unit 102 may be cut from a sheet of material, such as a closed or open cell polymer foam sheet. In one example, a resilient material such as foamed polymer sheet provides a desirable level of compliance that may allow a user to conform theophthalmic infusion support 100 to a patient for improved fixation as discussed below. In other examples, thebase unit 102 may be molded from a compliant polymer, or rigid polymer. Other materials such as metals are also possible, but may add unwanted cost to theophthalmic infusion support 100. - In the example of
FIG. 1 , an adhesive 120 is coupled to thebottom surface 104. The adhesive serves as a fixation device, and may be used to attach to a patient. In one example the adhesive such as a pressure sensitive adhesive is used. In the example ofFIG. 1 , a peel offbacking 122 is shown that may be removed to expose theadhesive 120 for attaching to a patient. - In one example, the
adhesive 120 is used to attach directly to a patient, such as adhering to the patient's skin in a region adjacent to an eye, as will be discussed in more detail below. In one example, a fixation device, such as the adhesive 120 is used to attach indirectly to a patient, such as attaching to a surgical drape that is place on the patient. Both direct fixation, and indirect fixation methods are encompassed in the present disclosure. Any number of suitable adhesives may be used as a fixation device, as discussed above. Other fixation devices include, but are not limited to, mechanical fixation, such as spring clips, pins, etc. Mechanical fixation device examples will primarily be used for indirect fixation to an intermediate element, such as a surgical drape. - The
ophthalmic infusion support 100 ofFIG. 1 further shows an infusiontube holding device 110 coupled to thetop surface 106 of thebase unit 102. In the example ofFIG. 1 , the infusiontube holding device 110 includes an adhesive 110. Theadhesive 110 may be the same or similar adhesive to theadhesive 120. In one example, afirst adhesive 110 is chosen to securely hold an infusion tube, while a second,different adhesive 120 is chosen to adhere to the patient, either directly or indirectly. - In one example an adhesive such as a pressure sensitive adhesive is used for the infusion
tube holding device 110. Similar to theadhesive 120, in the example ofFIG. 1 , a peel offbacking 112 is shown that may be removed to expose theadhesive 110 for attaching to an infusion tube. - Although an adhesive is shown as the infusion
tube holding device 110, the invention is not so limited. Other infusion tube holding devices may include mechanical holding devices, such as clips, clamps, fasteners, zip ties, etc. may be used as an infusiontube holding device 110. -
FIG. 2 shows anophthalmic infusion support 200 according to an example of the invention. Theophthalmic infusion support 200 includes abase unit 202 having abottom surface 204 and atop surface 206. Similar to theophthalmic infusion support 100, in one example thebase unit 102 is substantially flat in one dimension (for example in the plane of the page ofFIG. 1 ). As described above, materials for thebase unit 202 may include, but are not limited to, polymers, foamed polymers, metals, composites, etc. - Similar to the example of
FIG. 1 , an adhesive 220 is coupled to thebottom surface 204. The adhesive serves as a fixation device, and may be used to attach to a patient, directly or indirectly as discussed above. In one example the adhesive such as a pressure sensitive adhesive is used. In the example ofFIG. 2 , a peel offbacking 222 is shown that may be removed to expose theadhesive 220 for attaching to a patient. In the example ofFIG. 2 , thebottom surface 204 is anatomically curved to better conform and adhere to a patient, either directly or indirectly. - Similar to the example of
FIG. 1 , in one example an infusiontube holding device 210 is coupled to thetop surface 206 of thebase unit 202. In the example ofFIG. 2 , the infusion tube holding device 201 includes anadhesive 210. In one example an adhesive such as a pressure sensitive adhesive is used for the infusiontube holding device 210. Similar to the adhesive 220, a peel offbacking 212 is shown that may be removed to expose the adhesive 210 for attaching to an infusion tube. -
FIG. 3 shows an example of anophthalmic infusion support 300, similar to infusion supports 100 and 200 discussed above. Theophthalmic infusion support 300 is shown attached to a patient adjacent to the patient's eye. Aninfusion tube 310 is shown coupled to theophthalmic infusion support 300. Theinfusion tube 310 includes asupply end 312, and anoutlet end 314. Aloop 316 of theinfusion tube 310 is shown adjacent to the patient's eye. The loop projects upward from the patient as a result of being coupled to theophthalmic infusion support 300. - The
loop 316, and the upward projection provide comfort to the patient by allowing the infusion tube to move slightly without any excessive forces to the patient's eye. Example infusion support devices, such as infusion supports 100, 200, 300 and other examples as described in the present disclosure, help resist the weight of the tubing that may tend to pull a tip of the infusion line into unwanted orientations. Theloop 316, and the upward projection provide an infusion supply that is directed toward a desired portion of the eye, with unobstructed flow, and is much less likely to kink, twist, or otherwise become obstructed during a procedure. -
FIG. 4A further illustrates how examples of ophthalmic infusion supports provide a secure loop with an upward projection. In the example ofFIG. 4 , theinfusion tube 310 is attached to theophthalmic infusion support 300 along a top surface. In one example, theinfusion tube 310 is attached using an adhesive as described inFIGS. 1 and 2 . Other examples of attachment without adhesives are described in additional examples below, includingFIG. 4B . Theinfusion tube 310 ofFIG. 4 , includes aloop 316 that projects upward from the patient as depicted bysurface 304. Theloop 316 projects upward at anangle 320 from thesurface 304. In one example, the upward projection of theloop 316 provides a downward projection of thesupply end 314 of theinfusion tube 310. Such a configuration provides a reliable, substantially fixed angle of supply to an eye of the patient without unwanted misdirection of infusion flow, obstruction of infusion flow, kinking, twisting, etc. of theinfusion tube 310. - In the example of
FIG. 4A , the upward projection of theloop 316 is a direct result of aligning theinfusion tube 310 along an angled top surface of theophthalmic infusion support 300, however, the invention is not so limited. Other configurations may use other types of infusion tube holding devices to provide an upward projection of a loop. Selected other examples are discussed in more detail below. -

In one example, theophthalmic infusion support 1100 is wholly or partially formed from a resilient material, such as a polymer material, or flexible metal. In one resilient material example, atop portion 1106 may be tilted slightly to one side or the other in order to facilitate insertion of an infusion tube into the first or second infusiontube holding device tube holding devices - Although in one example, the entire
ophthalmic infusion support 1100 is formed from a resilient material, although the invention is not so limited. In one example, only a portion, such as a connectingregion 1108 is formed from a resilient material. In other examples, theophthalmic infusion support 1100 is formed from a rigid material, and a resilient nature of the infusion tube is used to hold the tube within either one of the first or second infusiontube holding devices - In all examples shown, the infusion tube holding devices provide an important feature of permitting a user to adjust an amount of infusion tube that extends beyond an end of an ophthalmic infusion support toward the patient. This allows a user to adjust a correct length of infusion tube to provide an optimal length of tubing to form a loop that projects upward from the patient. As discussed above, in one example, the upward projection of a loop provides a downward projection of a supply end of the infusion tube. Such a configuration provides a reliable, substantially fixed angle of supply to an eye of the patient without unwanted misdirection of infusion flow, obstruction of infusion flow, kinking, twisting, etc. of the infusion tube.
