Definitions
- a second elastic sleeve surrounds the first elastomeric sleeve, the second sleeve having an unstretched inner diameter which is less than the outer diameter of the elastomeric sleeve.
- the latex sleeve when a needle penetrates the latex sleeve and the blood tubing, and is thereafter withdrawn after injecting a medicament or taking a sample, the latex sleeve is intended to provide a seal against fluid leaks which occur through the needle puncture in the blood tubing.
- the prior art resealable injection site has also been observed to leak by the passage of fluid between the vinyl blood tubing and the latex sleeve, until fluid appears at the end of the latex sleeve as a continuous slow leak.
- the stretching in the latex sleeve is increased, which results in less capability to seal needle punctures.
- the sealing capability of a fluid conduit of biologically compatable tubing surrounded by an elastomeric sleeve injection site is improved by a second elastic sleeve surrounding the first elastomeric sleeve, in which the second elastic sleeve has an unstretched inner diameter which is less than the outer diameter of the first elastomeric sleeve.
- the second elastic sleeve prefferably be longer than the first elastomeric sleeve, and to overlie the ends of the elastomeric sleeve.
- the unstretched inner diameter of the second elastic sleeve should be less than the outer diameter of the biologi cally compatible tubing, to seal the ends of the first elastomeric sleeve against fluid leakage between the elastomeric sleeve and the tubing.
- the wall thickness of the second sleeve is also desirable for the wall thickness of the second sleeve to be less than one-half of the wall thickness of the elastomeric sleeve, and for-the inner diameter of the second sleeve to be less than the inner diameter of the elastomeric sleeve, so that the degree of stretching of the second sleeve is greater than that of the first elastomeric sleeve, and it tightly seals about the ends of the first sleeve.
- the' outer diameter of the first elastomeric sleeve as mounted on the tubing is at least about twice the inner diameter of the second elastic sleeve for high compression of the first elastomeric sleeve, although lesser degrees of compression can be used by providing a second sleeve of larger inner diameter.
- the first elastomeric sleeve is preferably made of natural latex or any other elastomeric material having excellent needle puncture resealing characteristics.
- the second elastic sleeve is also conveniently made of natural latex, although any elastic material having generally equivalent tensile strength can be used. However, it is generallydesi rable for the second sleeve to also have excellent I needle puncture resealing characteristics equivalent to natural latex.
- the second elastic'sleeve can be made of a material which shrinks upon drying of solvent in the material or upon heating,
- FIG. 2 is a longitudinal sectional view taken along line 2-2 of FIG. 1, and enlarged in size.
- FIG. 3 is a transverse sectional view taken along line 3-3 of FIG. 1 and enlarged in size.
- tubing 10 is shown as a conduit for blood in a medical device such as a conventional arterial or veinous set for an artificial kidney. Such sets are commercially available at the present time from Travenol Laboratories, Inc. of Morton Grove, Ill. Tubing 10 might also be part of a blood line in a blood oxygenation system. Tubing 10 can be made of any needle-puncturable, biologically compatible material, for example, plastic materials including vinyl plastisol or polyurethane, and silicone rubber.
- the improved injection site 12 of this invention comprises an elastomeric sleeve 14 surrounding a portion of tubing 10.
- the unstretched inner diameter of elastomeric sleeve 14 is smaller than the outer diameter of tubing 10 to provide a compressive seal at the interface 22 between sleeve 14 and tubing 10.
- Second elastic sleeve 16 overlies the first elastomeric sleeve 14, and is longer than elastomeric sleeve 14, so that overlying portions 18, 20 cover the ends of sleeve 14 and provide sealing against any fluid leakage that takes place along the interface 22 between tubing 10 and elastomeric sleeve 14 after puncture by a needle 24, shown in phantom in FIG. 2.
- Sleeve 16 has less than half the wall thickness of sleeve 14, to permit it to closely conform about the ends of sleeve 14 for improved sealing.
- Second sleeve 16 is proportioned to compress elastomeric sleeve 14, which compression .provides improved sealing of needle puncture holes through sleeve 14 after the puncturing needle 24 has been withdrawn.
- the inner diameter of second sleeve l6' is less than the unstretched outer diameter of sleeve 14, so that sleeve 14 is substantially compressed.
- tubing l in one suitable'form, tubing l has an inner diameter of about 0.18 to 0.2 inch and a wall thickness of about 0.06 to 0.07 inch, to give a total outer diameter of about 0.3 to 0.34 inch.
- elastomeric sleeve 14 can have an unstretched inner diameter of about 0.2 to 0.3 inch and a wall thickness'of about 0.09 to 0.1 inch.
- the inner diameter is 0.312 inch and the wallthickness 0.094 inch, to give a total outer diameter of 0.5 inch.
- the outer diameter of tubing is 0.34 inch.
- second elastic sleeve 16 may have an inner diameter of about 0.25 inch and a wall thickness of about 0.03. inch. It can thus be seen in the above specific embodiment that the outer diameter of elastomeric sleeve 14 is about twice the inner diameter of second sleeve .16 in the above specific embodiment. Accordingly, sleeve 14 is placed under quite substantial compression by second sleeve 16, which results in an improvement in the sealing characteristics of sleeve 14. Similarly, since the unstretched inner diameter of second sleeve 16 is less than the outer diameter of tubing 10, an additional pressure seal is applied to tubing 10 by end portions 18, 20, resulting in additional sealing about the ends of elastomeric sleeve 14.
- tubing 10 has an inner diameter of 0.187 inch and a wall thickness of 0.063 inch, while elastomeric sleeve 14 has an inner diameter of 0.25 inch and a wall thickness of 0.094 inch.
- the remaining dimensions are similar to the previous embodiment.
- Elastomeric sleeve 14 is generally about 2 to 6 inches long, while second sleeve '16 is about 1 to 3 inches longer than sleeve 14, to provide suitable sealing about the ends of sleeve 14.
- Sleeves 14 and 16 can be placed upon tubing 10 simply by expanding them with a suitable expansion fork made of a plurality of rods, and lever means for spreading the rods apart, to stretch the sleeves while threading them onto tubing 10 to the desired position. Then the expansion fork is allowed to collapse, and is withdrawn from the inside of each sleeve. Likewise, sleeves l4, 16 can be threaded upon a suitably sized rigid collet, and threaded on the tubing 10, the collet being then withdrawn.
- a conduit for blood' and the like which comprises needle puncturable, biologically compatible tubing, a portion of said tubing being surrounded by an elastomeric sleeve injection site, the improvement comprising a second, elastic sleeve surrounding said elastomeric sleeve, said second sleeve having an unstretched inner diameter which is less than the outer diameter of said puncturable tubing, to compress said elastomeric sleeve, whereby the sealing of said elastomeric sleeve after puncture by a needle is improved, and in which said second, elastic sleeve is longer than said elastomeric sleeve and overlies the ends of said elastomeric sleeve, to seal the ends of said elastomeric sleeve against fluid leakage between the. elastomeric sleeve and the tubing.
- the blood conduit of claim 2 in which said tubing has an inner diameter of about 0.18 to 0.2 inch and a wall thickness of about 0.06 to 0.07 inch; said elastomeric sleeve has an unstretched inner diameter of about 0.2 to 0.3 inch and a wall thickness of about 0.09 to 0.1 inch, and said second, elastic sleeve has an unstretched inner diameter of about 0.25 inch and a wall thickness of about 0.03 inch.
