Description Injection Site With Tamper Indicator TECXNICAL FIELD
The present invention concerns an injection site 5 which carries a device for indicating that an injection has occurred or that the injection site has been tampered with.
BACKGROUND ART
Injection sites are commonly used in hospitals where a parenteral fluid is being fed to a patient intravenously and it is also desired to combine another medicament with the parenteral fluid. In such circumstances, the paren-teral fluid is fed via flexible conduit to one inlet of a connecting device, commonly called an injection site. Flex-ible conduit extends from the outlet of the injection siteto an appropriate device for administering the liquid to the patient. The injection site typically has a second inlet, having a pierceable diaphragm connected thereto.
The supplementary medicament is injected into the second inlet by a hypodermic syringe and it becomes combined with the parenteral liquid for administration to the patient.
A type of injection site which comprises the above-de-scribed characteristics is disclosed in Herbert Mittleman U.S. Patent No. 4,000,7~0, issued January 4, 1977, and en-titled "Injection Site".
The pierceable diaphragm is formed of a self-seal-able material, such as Latex or silicone rubber, and it is often impossible to determine whether an injection has been made into the diaphragm by merely viewing it. In addition, since prior art injection sites generally uti-lize pierceable diaphragms which are exposed to ambient 115~1~5 surroundings, it is possible for the pierceable diaphragm to have come in contact with various fluid contaminants without anyone knowing whether such has occurred. Further, if the injection site is not stored properly, a layer of dust may collect upon the pierceable diaphragm.
DISCLOSURE OF THE INVENTION
It is an object of the present invention to provide means for determining whether injection into the pierce-able diaphragm has occurred or whether tampering has oc-curred.
Another object of the present invention is to pro-vide tamper indicating means for an injection site, which also serves to prevent the pierceable diaphragm of the injection site from being contaminated with dust or cer-tain gross contaminants.
Another object of the present invention is to pro-vide an injection site including tamper indicating means that is simple in construction and efficient to manufac-ture.
A still further object of the present invention is to provide tamper indicating means for an injection site, which renders the pierceable diaphragm inaccessible until a portion of the tamper indicating means is removed.
Other objects and advantages of the present inven-tion will become apparent as the description proceeds.
In accordance with the present invention, a tamper indicating device is provided for connection to an injec-tion site having a main body portion, a first inlet, a second inlet including a pierceable, self-sealing member, 30 an outlet, and with the first inlet, second inlet and out-let being in fluid communication with the main body por-tion. The tamper indicating device comprises a cap cover-11 5 ~
ing the second inlet and rendering the pierceable, self-sealing member inaccessible. The cap comprises a first portion for connection to the second inlet and a second portion separated from the first portion by a frangible 5 section. A handle extends from the second portion and is operable when actuated to break the second portion away from the first portion at the frangible section. In this manner, the pierceable, self-sealing member becomes access-ible while the first portion remains connected to the sec-10 ond inlet.
In the illustrative embodiment, the first portioncomprises a ring member substantially encircling the sec-ond inlet. The second portion comprises a cup-shaped mem-ber and the frangible section comprises an annular thin section coupling the first portion to the second portion.
The tamper indicating means has a color that is different from the color of the second inlet so that when the second portion is broken away from the first portion, the color of the first portion which remains connected to the second inlet will contrast with the color of the second inlet, to show that the injection site had a tamper indicating device that has been partially removed.
A more detailed explanation of the invention is pro-vided in the following description and claims, and is il-lustrated in the accompanying drawings.

DETAILED DESCRIPTION OF
THE IL~USTRATIVE EM~ODIMENT
Referring to Figures 1 and 6 in particular, the in-jection site 10 illustrated therein comprises a first inlet 12 for connection to a tube leading to a parenteral source of liquid, a second inlet 14 (Figure 6) having a pierceable self-sealing diaphragm located therein as is well-known in the art, an outlet 18 for coupling to tubing which is con-nected to a patient, a main body portion 20 with which in-lets 12 and 14 and outlet 18 communicate, and a ridge 22connecting inlets 12 and 14 ~o aid in preventing tubing from becoming caught between these inlets. Such an injec-- tion site is illustrated in a pending Canadian patent appIication in the name of Herbert Mittleman, Serial No.
322,945, filed March 7, 1979. Referring to Figure 6, it can be seen that the top plane of pierceable diaphragm 16 is generally coplanar with the top of second inlet 14.
Inlet 14 is substantially encircled and covered by tamper indicating device 24. Tamper indicating device 24 is formed in a one-piece integral molded construction, and comprises a fir~t portion 26, which is cylindrical with its internal wall being solvent bonded to the external wall of second inlet 14, a second portion 28 which is generally cup-shaped and is separated from first portion 26 by a fran-gible section 30, and a handle 32 which is a generally flatmember extending perpendicular to the axis of cup-shaped second portion 28 (and thus perpendicular to the axis of second inlet 14).
Frangible section 30 comprises an annular thin sec-tion, as most clearly illustrated in Figure 3, with fran-gible section 30 being in general alignment with the top of second inlet 14. For rigidity purposes, i.e., in order to prevent handle 32 from breaking away from second portion 28, a gusset 34 bridging the underside of handle 32 and a ~`
~15~1i5 side of second portion 28 is provided.
One side of tamper indicating device 24 defines arectangular slot 36 (Figure 4) which extends from the bottom 38 of first portion 26 to a level just above the frangible section 30. This slot 36 is of a width to accommodate ridge 22, whereby the first portion 26 will encircle sec-ond inlet 14 except for ridge 22. Slot 36 is such that its top wall 40 is above the plane of the top of inlet 14, thereby providing a small opening so that inlet 14 can be ethylene trioxide sterili~ed notwithstanding the presence of tamper indicating device 24 thereon.
With reference to Figure 1, it can be seen that when tamper indicating device 24 is on second inlet 14, pierce-able diaphragm 16 is inaccessible. In order for pierce-able diaphragm 16 to become accessible, handle 32 is liftedupwardly to break the frangible section 30 so that second portion 28 can be removed from first portion 26. When second portion 28 is removed, the first portion 26 will remain attached to second inlet 14 as illustrated in Fig-ure 6.
The tamper indicating device 24 is formed of a plas-tic having a different color than the color of second in-let 14, so that once handle 32 and second portion 28 are removed, an operator can readily see that a portion of the tamper indicating device 24 has been removed. As an example, although no limitation is intended, the tamper indicating device 24 may be a bright color, such as red, while second inlet 14 may be white.
Although an illustrative embodiment of the inven-tion has been shown and described, it is to be understoodthat various modifications and substitutions may be made by those skilled in the art without departing from the novel spirit and scope of the present invention.

Referring to Figures 1 and 6 in particular, the in-jection site 10 illustrated therein comprises a first inlet 12 for connection to a tube leading to a parenteral source of liquid, a second inlet 14 (Figure 6) having a pierceable self-sealing diaphragm located therein as is well-known in the art, an outlet 18 for coupling to tubing which is con-nected to a patient, a main body portion 20 with which in-lets 12 and 14 and outlet 18 communicate, and a ridge 22connecting inlets 12 and 14 ~o aid in preventing tubing from becoming caught between these inlets. Such an injec-- tion site is illustrated in a pending Canadian patent appIication in the name of Herbert Mittleman, Serial No.
322,945, filed March 7, 1979. Referring to Figure 6, it can be seen that the top plane of pierceable diaphragm 16 is generally coplanar with the top of second inlet 14.
Inlet 14 is substantially encircled and covered by tamper indicating device 24. Tamper indicating device 24 is formed in a one-piece integral molded construction, and comprises a fir~t portion 26, which is cylindrical with its internal wall being solvent bonded to the external wall of second inlet 14, a second portion 28 which is generally cup-shaped and is separated from first portion 26 by a fran-gible section 30, and a handle 32 which is a generally flatmember extending perpendicular to the axis of cup-shaped second portion 28 (and thus perpendicular to the axis of second inlet 14).
Frangible section 30 comprises an annular thin sec-tion, as most clearly illustrated in Figure 3, with fran-gible section 30 being in general alignment with the top of second inlet 14. For rigidity purposes, i.e., in order to prevent handle 32 from breaking away from second portion 28, a gusset 34 bridging the underside of handle 32 and a ~`
