Combination lock for blood identification system
First Claim
1. A combination lock assembly comprising:
- (a) a base member;
(b) locating means frangibly attached to the base member;
(c) a plurality of locking rings mounted on the base member, each locking ring defining notch means, and engagement means to engage the locating means so as to non-rotatably mount the locking rings on the base member such that the notch means are aligned;
(d) an indicia ring associated with each locking ring;
(e) a clasp member adapted to be attached to the base member so as to retain the base member, the locking rings and the indicia rings in assembled relationship; and
(f) attachment means to attach the clasp member to the base member in first and second positions such that, in the first position the indicia rings may be rotated with respect to their associated locking ring so as to align a desired indicia with the notch means to thereby set the combination and, in the second position, the locating means are detached from the base member thereby permitting the locking rings to rotate with respect to the base member.

Abstract
A system is disclosed for positive identification between a patient and a blood unit to be administered to the patient incorporating a combination lock which positively prevents access to the blood unit unless its code matches that of the patient. An alphabetic code is assigned to the patient and is set into the combination lock at the time the blood unit is removed from the blood bank. Setting of the code is achieved by the technician without necessity of external tools or mechanical skill. The combination lock has several alphabetic coded indicia dials which may be set at any orientation with respect to several locking rings. Once the combination is set, a manual clamping force exerted on the structure serves to lock the indicia rings to the associated locking ring to set the code.

8. A coded receptacle locking system comprising:
-
(a) a receptacle formed of flexible material having an opening defined by opposite walls; (b) a holder element adapted to extend through the opposite walls; and
,(c) a combination lock element adapted to engage the holder element so as to grip the opposite walls therebetween wherein the combination lock element comprises; (i) a base member; (ii) locating means frangibly attached to the base member; (iii) a plurality of locking rings mounted on the base member, each locking ring defining notch means and engagement means to engage the locating means so as to non-rotatably mount the locking rings on the base member such that the notch means are aligned; (iv) an indicia ring associated with each locking ring; (v) a clasp member adapted to be attached to the base member so as to retain the base member, the locking rings and the indicia rings in assembled relationship; and (vi) attachment means to attach the clasp member to the base member in first and second positions such that, in the first position the indicia rings may be rotated with respect to their associated locking ring so as to align a desired indicia with the notch means to thereby set the combination and, in the second position the locating means are detached from the base member thereby permitting the locking rings to rotate with respect to the base member. - View Dependent Claims (9, 10, 11, 12, 13)

14. A patient blood identification and locking system comprising:
-
(a) coded indicia means attached to the patient; (b) an opaque receptacle formed of flexible material having an opening defined by opposite walls, the receptacle adapted to hold a blood unit bag; (c) a holder element adapted to extend through the opposite walls of the container; (d) a combination lock element having indicia thereon and adapted to engage the holder element so as to grip the opposite walls of the receptacle therebetween and thereby prevent removal of the blood unit bag wherein the combination lock element comprises; (i) a base member; (ii) locating means frangible attached to the base member; (iii) a plurality of locking rings mounted on the base member, each locking ring defining notch means and engagement means to engage the locating means so as to non-rotatably mount the locking rings on the base member such that the notch means are aligned; (iv) an indicia ring associated with each locking ring; (v) a clasp member adapted to be attached to the base member so as to retain the base member, the locking rings and the indicia rings in assembled relationship; and
,(vi) attachment means to attach the clasp member to the base member in first and second positions such that, in the first position the indicia rings may be rotated with respect to their associated locking ring so as to align a desired indicia with the notch means to thereby set the combination and, in the second position the locating means are detached from the base member thereby permitting the locking rings to rotate with respect to the base member; and
,(e) means to encode the patient'"'"'s coded indicia into the combination lock element such that it will release the holder element only when its indicia matches that of the patient. - View Dependent Claims (15, 16, 17, 18, 19)
