3 Claims. (Cl. '1283'50) This invention relates to means for retaining surgical devices such as a drainage tube, catheter, or the like in position on the body of a patient.
It is often necessary .to leave such devices as nephrostomy or other type drainage tubes or catheters in place particularly when a splinting catheter or a drainage catheter having a Pezzar or Malecot head is used. Many arrangements have been improvised in an attempt to anchor such devices. Adhesive straps and bandage have been used and at times the catheter has even been sutured to the skin of the patent. Nevertheless, a patent may, on moving, displace the catheter so that it becomes completely removed from the wound. This has necessitated a second operation with reopening of the wound to replace the catheter.
It is, therefore, a principal object of this invention to provide a retention disk which may be readily removably aflixed to the body of a patent and which serves to removably anchor in the desired location on the body of a patient surgical devices such as drainage tubes or catheters or the like.
Further objects as well as advantages of the present invention will be apparent from the following description of a preferred embodiment thereof and the accompanying drawing in which Figure 1 is a rear elevational view of a retention disk constructed in accordance with the present invention;
Figure 2 is a cross-sectional view through the line 2-2 of Figure '1;
Figure 3 is a fragmentary view similar to Figure 2 showing the device inflated;
Figure 4 is a cross-sectional view through the line 4-4 of Figure 2;
Figure 5 is a cross-sectional view through the line 5-5 of Figure 3; and
Figure 6 is an elevational view partially diagrammatic showing the retention disk affixed to the body of a patient and anchoring a catheter in place.
Referring now to the drawing in detail, retention disk 10 comprises a generally flat, soft, pliable disk portion 11, which may be annular as shown, having an aperture 12 which communicates with the bore 13 of a tube 14 joined with disk portion 11 and projecting from the rearward surface thereof. Tube 14 branches adjacent to its rearward end to form an inflating tube 15 the rearward end portion of which may have a somewhat increased diameter to facilitate insertion of a plug 16. A resilient sleeve 17 having a substantially thinner wall thickness than the wall of tube 14 is sealed in an airtight manner adjacent to its ends to the inner wall of tube 14. The intermediate portion of sleeve 17 which is free and not secured directly to tube 14 forms an annular sack therewith which communicates through passageway 18 with the bore 19 of inflating tube 15.
Plug 16, which closes the end of tube 15, is formed of resilient material such as rubber which closes on itself after having been pierced by and following withdrawal of an inflating instrument. The inflatable sack formed by sleeve 17 is conveniently inflated with a suitable fluid, such as water or air, by forcing a needle aflixed to a syringe through plug 16. As shown in Figures 3 and 5,.sack 17a inflates to form two annularly spaced protuberances which engage and retain a member extending in the bore of tube 14.
Retention disk 10 is conveniently formed of rubber latex, suitable thicknesses in the shapes desired being' built up as is well known in the art. Because of the manner in which rubber latex members may be readily united so as to be virtually integral one with the other, the finished product, for all practical purposes presents a continuous, integral surface which is readily maintained sterile.
Referring now to Figure 6, the forward end of the surgical device which is to be retained to disk 10, such as catheter 21, is passed through the bore of tube 14 and introduced into the body cavity. The forwardly presented surface of disk portion 11 is coated with a suitable adhesive and the retention disk is moved along the tube of catheter 21 until it is snug against the skin of the patient. The disk readily conforms to the contours of the patients body. The inflating fluid is then introduced into sack 17a which distends to engage but not close the catheter tube. The adhesive may be any suitable surgical skin adhesive but preferably is one which does not have any deleterious effect upon either the skin of the patient or upon the material of which the disk is made. It should be readily removable without leaving any obectionable residue.
The terms and expressions which have been employed are used as terms of description and not of limitation, and there is no intention in the use of such terms and expres sions of excluding any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
What is claimed is:
l. A surgical retaining device, comprising a disk adapted to conform to and to be anchored to a portion of the body of a patient, a tube joined with and extending from one surface of said disk, said tube having a bore oommunicating through an opening formed in said disk with the opposite side thereof, a resilient member secured to a portion of the inner surface of said tube and having a free portion intermediate the ends thereof forming a chamber with said tube, and means for inflating said chamber to distend said free portion of said resilient member into the bore of said tube and thereby anchor a surgical device such as a catheter extending through said tube bore.
2. A surgical retaining device, comprising a disk having an aperture formed therethrough, a first tube joined with and extending from one surface of said disk with its bore in registration with said aperture, said disk being adapted to conform to and to be adhesively removably anchored to the body of a patient with said aperture and bore in registration with an opening into the patients body, a distendable member which is more readily distendable than said first tube, said distendable member extending within said first tube and having its edge portions sealed to said first tube so as to form an airtight enclosure therewith, and an inflating tube having a bore communicating through the wall of said first tube with the interior of said enclosure, whereby a surgical device such as a catheter or the like extending through the bore of said tube into the body opening of the patient is anchored in place when said enclosure is inflated and thereby distended to engage said device.
3. A surgical retaining device, comprising a disk hav- 3 ing an aperture formed therethrough, a first tube joined with and extending from one surface of said disk with its bore in registration with said aperture, said disk being adapted to conform to and to be adlumively removably anchored to the body of a patient with said aperture and bore in registration with an opening into the patients body, a second tube formed of resilient material which is more readily 'distendable than said first tube, said second tube extending within said first tube and having its end portions sealed to said first tube so as to form an airtight enclosure therewith, and an inflating tube having a bore communicating through the wall of said first tube with the interior of said enclosure, whereby a surgical device such as a catheter or the like extending through the bore of said tube into the body opening of the patient is anchored in place when said enclosure is inflated and thereby distended to engage said device.
