Urine sample collection apparatus

Abstract

An apparatus and method for automatically collecting urine samples from a patient are described. The apparatus includes a toilet bowel with a reservoir and a urine collection receptacle that is a flexible heat sealable plastic bag in an enclosure mounted exterior to the reservoir. The receptacle can be rotated into the toilet reservoir to collect urine and removed therefrom by rotating it back into the enclosure. The opening to the bag is then heat sealed to produce a urine sample packet. The receptacle may be automatically divided into a plurality of urine sample packets by heat sealing the bag at several locations along its length and then cutting the bag at the appropriate heat sealed locations. Each packet is then printed with patient indicia. The sample packets then pass through an opening in the enclosure for removal and subsequent analysis. An electrical activation interface is provided to control the process.

SUMMARY OF THE INVENTION

This invention is directed to a urine sample collection system that is integral with a toilet system. The system is fully automated to produce one or plurality, e.g., from 1-3, of sealed urine sample packets for further processing and analysis in the laboratory.

The apparatus includes a toilet bowel with a reservoir and a urine collection receptacle that is a flexible heat sealable plastic bag. The bag is in an enclosure mounted exterior to the reservoir. The receptacle can be activated to automatically rotate into the toilet reservoir to collect urine and then removed therefrom by rotating it back into the enclosure. The opening to the bag is then heat sealed to produce a urine sample packet. The receptacle may be automatically divided into a plurality of urine sample packets by heat sealing the bag at several locations along its length and then cutting the bag at the appropriate heat sealed locations. Each packet is then printed with patient indicia. The sample packets then pass through an opening in the enclosure for removal and subsequent analysis. An electrical activation interface is provided to control the process.

DESCRIPTION OF THE INVENTION

FIG. 1 and FIG. 2

Referring to FIGS. 1 and 2, the collection system may be used as the regular, well known toilet system, e.g., toilet bowl. When used in this manner, no urine samples are collected.

As shown in FIGS. 2-14, the collection system is structured and functions to collect one or a plurality of urine sample packets. The collection system goes through several steps to collect from a patient sitting on the bowl at least one, and preferably a plurality of sealed urine sample packets that are labeled with patient information.

FIG. 3 is perspective of the urine collection system of this invention referencing the parts of the invention, the parts being color coded in the Figures:

Toilet seat: This is the seat the patient sits on for conventional use of the urine collection system as a toilet and for the collection of urine.

Regular toilet reservoir: This is a bowel for collecting waste materials when used in the conventional manner. Although not shown, this may be hooked up to the toilet system in the room in which the collection system is situated.

Dispenser for urine collection: This is initially positioned in front of the toilet seat as depicted in FIGS. 3 and 4.

Urine collection receptacle: This is a receptacle for receiving the Disposable urine collector and any overflow of urine.

Disposable urine collector: This is a disposable container, preferable a flexible heat sealable, plastic bag that directly receives the urine.

Door for dispensed urine collector: This is a door in the side of the collector system that permits selective access to the interior and removal of the specimen urine sample packets from the collector system.

Ramp for dispensing the urine collector: After the disposable urine collector is sealed into urine sample packets and a printed label adhered thereto, it exits through this ramp to the door.

Trash for discarded disposable urine collection: A receptacle for the disposable packaging material from the disposable urine collector.

Labeling printer: positioned and integrated into the collection system to print critical patient data on the specimen urine packets.

Seal & Cut arms: These are the means for cutting and sealing the disposable urine collector packaging into sample sized sealed specimen urine sample packets for shipment to the laboratory.

FIG. 4 depicts the interior structure of the urine collection system. In this position, the urine collection receptacle (A) is outside the toilet reservoir (B). The edge of the urine collection receptacle (C) creates a water tight seal with the toilet reservoir so that the toilet can be flushed without water leaking out.

FIG. 5 depicts an electronic interface that is integrated into the collection system. The electronic interface activates the collection system and the steps that are part of the process for collecting and “packaging” the urine sample. The electronic interface may be wall mounted near the collection system or on a wall outside the area, e.g., hard wired, where the collection system is located. The collection system may also be activated through an internet and/or Wi-Fi interface, e.g., an “App” for an I-phone or I-Pad or through a desk top computer program.

As shown in FIGS. 4 and 6, the system has a first area 50, a second area 52, and a rotating shaft 60 adapted to move the urine collection receptacle (A) between the first area 50 and the second area 52.

FIG. 6 depicts the urine collection system just prior to collecting urine. The urine collector receptacle is rotated into the toilet's reservoir (D). The disposable urine collector is positioned directly under the toilet seat (E) to collect the patient's urine.

Referring to FIGS. 7 and FIGS. 7a-7c:

FIG. 7a depicts the urine collector receptacle moved into position in the toilet reservoir and the disposable urine collector positioned directly under the toilet seat. The urine falls into the disposable urine collector.

FIG. 7b depicts the disposable urine collector having built in drain spouts (F) to drain any excess urine into the water in the toilet reservoir.

FIG. 7c depicts the disposable urine collector after the excess urine flows out and there remains a predetermined amount of urine therein.

Referring to FIGS. 8 and FIGS. 8a and 8b:

FIG. 8a depicts the urine collector receptacle rotated back to its initial position (as in FIG. 8) with the predetermined amount of urine in the disposable urine collector.

FIG. 8b depicts a means for sealing and cutting the disposable urine collector into one or more urine sample packets. As depicted, sealing & cutting arms (G) close onto the disposable urine collector. The dispenser ramp moves under the disposable urine collector (H)

FIGS. 9 and 9 a, 9b and 9c through the electronic interface, as depicted in this example, the technician has the option of choosing through the interface, one, two or three urine sample packets to be sealed and cut from the disposable urine collector. The urine sample packets are then dropped onto the dispenser ramp and subsequently passed through the door, see FIG. 10. This invention envisions that any number of urine sample packets can be made, although a maximum of three are depicted in this embodiment.

FIGS. 10 and FIGS. 10a-c depict the labeling and dispensing of the urine sample packets:

FIG. 10a depicts the urine sample packet falling onto the dispenser ramp juxtaposed over the label printer.

FIG. 10b depicts the urine sample packet sliding down the ramp and over a printed label having an adhesive backing that adheres to the packet.

FIG. 10c depicts the final (hermetically) sealed urine sample packet having the printed label on the packet with the relevant patient information ready to be sent to the laboratory for testing.

FIG. 11-14 depicts resetting the urine collection system to enable another test process to take place.

FIG. 11 depicts the dispenser ramp moved out of position. The holding mechanisms of the disposable urine collector (I) releases and drops the remainder of the disposable urine collector into the trash receptacle (J).

FIG. 12 depicts the disposable urine collector loader moves down and installs the next sterile disposable urine collector.

FIG. 13 depicts the holding mechanisms (I) of the disposable urine collector engaged to hold it in place. The loader moves back up.

FIG. 14 depicts the urine collection system repositioned for the next patient.

While the invention has been described in connection with what is presently considered to be practical and preferred embodiments thereof, it should be understood that it is not to be limited or restricted to the disclosed embodiments, but rather is intended to cover various modifications, substitutions and combinations within the spirit and scope of the described invention.
