Abstract
Abstract Medical apparatus and method for preventing infectious organisms from entering the body of a patient through or along a catheter. The apparatus includes a tubular receptacle through which body fluids flow from the catheter to a collecting reservoir, the receptacle adapted in various ways to facilitate introduction of antiseptic compositions from either liquid or solid form into the body fluids to preclude survival therein of infectious organisms. Also disclosed is apparatus for maintaning an antiseptic barrier on the outside of the catheter where it enters the patient''s body.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
129 words
An apparatus for preventing infectious organisms from entering the body of a medical patient through or along a catheter for removing body fluids, comprising: a. a catheter having an inner end portion for insertion into a patient''s body and an outer end portion for conducting body fluids to a collection reservoir, and b. a means for preventing the migration of infectious organisms through and around said catheter from a body fluid flow collection means to a fluid flow discharge source in said body comprising a receptacle having an antiseptic discharge contacting and mixing means in the path of flow of said fluids whereby because of said mixture of antiseptic and body fluids infectious organisms in said body fluids are prevented from migrating through the catheter and into the patient.
Claim 2
Independent Claim
129 words
An apparatus for preventing infectious organisms from entering the body of a medical patient through or along a catheter for removing body fluids, comprising: a. a catheter having an inner end portion for insertion into a patient''s body and an outer end portion for conducting body fluids to a collection reservoir, and b. a means for preventing the migration of infectious organisms through and around said catheter from a body fluid flow collection means to a fluid flow discharge source in said body comprising a receptacle having an antiseptic discharge contacting and mixing means in the path of flow of said fluids whereby because of said mixture of antiseptic and body fluids infectious organisms in said body fluids are prevented from migrating through the catheter and into the patient.
Claim 3
Dependent Claim
32 words
An apparatus according to claim 1 wherein the receptacle includes an inlet for admission of body fluids and an outlet for maintaining a liquid seal between said receptacle and the collection reservoir.
Claim 4
Dependent Claim
18 words
An apparatus according to claim 2 wherein the receptacle includes a perforate screen between said inlet and outlet.
Claim 5
Dependent Claim
54 words
An apparatus according to claim 2 wherein said outlet comprises an inverted cone-shaped wall with a central opening at the bottom end of said receptacle, said wall thereby functioning as a funnel to collect and conduct the mixture of body fluids and antiseptic to the central opening for subsequent passage therethrough in droplet form.
Claim 6
Dependent Claim
28 words
An apparatus according to claim 2 wherein the inlet includes valve means for preventing flow of liquid from said receptacle into the catheter towards its inner end portion.

Claim 11
Dependent Claim
50 words
An apparatus according to claim 1 including an antiseptic ointment retainer through which the catheter''s inner end portion extends, said retainer including means for retaining an antiseptic ointment in place between the catheter and the adjacent surface of a patient''s body when the catheter is properly installed in functional position.
Claim 12
Dependent Claim
20 words
An apparatus according to claim 10 wherein the ointment retainer includes a flexible sheath portion for use with male patients.
Claim 13
Dependent Claim
20 words

Claim 14
Independent Claim
50 words
A method for preventing infectious organisms from entering a medical patient''s body by the way of a catheter connected to a collection reservoir, comprising mixing an antiseptic with discharged body fluids flowing through the catheter to form an antiseptic liquid barrier between the catheter and the body fluid collection reservoir.
Claim 15
Independent Claim
50 words
A method for preventing infectious organisms from entering a medical patient''s body by the way of a catheter connected to a collection reservoir, comprising mixing an antiseptic with discharged body fluids flowing through the catheter to form an antiseptic liquid barrier between the catheter and the body fluid collection reservoir.
Claim 16
Dependent Claim
13 words
A method according to claim 13 wherein the antiseptic is in liquid form.
Claim 17
Dependent Claim
15 words
A method according to claim 13 wherein the antiseptic is in water soluble, solid form.
