US 5,327,897 A · Multifunction collecting device for body fluids

Abstract

Methods and devices for collecting at least two separate samples of a body fluid (e.g., blood) simultaneously. The device is introduced into a body of a living being whose blood is to be analyzed at a preexisting accessible cavity of the body which at least temporarily contains blood of the living being. The device has an interior having first and second hollow retaining compartments capable of receiving and holding the blood which is present in the cavity when the entire device is introduced into and remains wholly within the cavity. After the device is removed from the body cavity, blood is removed from the first and second hollow retaining compartments, such that the blood can be simultaneously separately collected and prepared for subsequent separate and different analyses. The first and second hollow retaining compartments are adapted to collect blood having similar characteristics. In a preferred embodiment, the first and second retaining compartments each contain an absorbent medium such as a sponge. In a further preferred embodiment, the first and second retaining compartments further include an additive selected from the group consisting of a fixative, a preservative, nutrients, red cell stabilizers, an antibacterial, a germicide, an agglutinin, a surfactant, a detergent, an antibiotic, an additive to prevent hemolysis, and monoclonal antibodies, the additive within the first hollow retaining compartment being different from the additive within the second retaining compartment.

A device made of a biocompatible material for collecting a body fluid in a body cavity, comprising means for inserting said device into said body cavity, said means comprising,

an exterior portion,
an interior portion said device further comprising, said interior portion comprising,
a single passage connecting said interior portion to said exterior portion of said device, the body fluid flowing through said passage into said interior portion from said exterior portion,
a first hollow retaining compartment for collecting a sample of body fluid when the device is situated in a body cavity, and
a second hollow retaining compartment for collecting a second sample of body fluid when the device is situated in the body cavity, said second hollow retaining compartment being structured and arranged to collect body fluid having similar characteristics as that collected in said first hollow retaining compartment, said single passage connecting said first and second hollow retaining compartments to said exterior portion of said device, and
retaining means situated in each of said first and second retaining compartments, at least a portion of the body fluid passed through said passage and into said interior portion and thereafter collected in said first and second retaining compartments being retained on said retaining means, the body fluid being simultaneously passed from said interior portion and separately collected in both of said first and second retaining compartments and prepared for subsequent separate and different analyses of the collected body fluid from each of said first and second retaining compartments.

In a method for collecting and analyzing the blood of a living being, the steps of providing a device having an interior having first and second hollow retaining compartments each having retaining means therein capable of receiving and holding blood which is present in the cavity when the entire device is introduced into and remains wholly within the cavity, said interior having a single passage structured and arranged to pass blood from the cavity through said passage and simultaneously to both of said first and second hollow retaining compartment,

introducing into a body of a living being whose blood is to be analyzed, at a preexisting accessible cavity of the body which at least temporarily contains blood of the living being, said device being introduced in the cavity at a time which will assure presence of the device in the cavity when blood is present therein,
removing the device from the body cavity after the device has remained therein for a period of time sufficient to receive and hold blood of the living being, so that blood is removed with the device, said second hollow retaining compartment being adapted to collect blood having similar characteristics as that collected in said first hollow retaining compartment,
providing said retaining means within said first and second hollow retaining compartments prior to introduction of the device into the body cavity with an additive selected from the group consisting of a fixative, a preservative, nutrients, red cell stabilizers, an antibacterial, a germicide, an agglutinin, a surfactant, a detergent, an antibiotic, an additive to prevent hemolysis, and monoclonal antibodies, the additive within said first hollow retaining compartments being different than the additive within said second hollow retaining compartment, subjecting at least part of the blood contained within said first hollow retaining compartment to a first analysis, and
subjecting at least part of the blood contained within said second hollow retaining compartment to a second analysis different than said first analysis.
