Packaging that facilitates sample collection
An article of manufacture composed of tray-like packaging unit characterized by a first section designed to hold a sample analysis slide and a second section designed to hold a sample collection device. Molded into the tray-like packaging unit are a thermoformed well designed to accept a patient's liquid sample from a pipette or syringe, a splash wall formed between the first section and the second section designed to contain the patient's liquid sample in the thermoformed well, and an overflow reservoir designed to hold excess patient sample placed in the thermoformed well. Also molded into the sidewalls of tray-like packaging unit are projections designed to allow the sample analysis slide and the sample collection device to be snapped into the packaging unit resulting in a secure configuration for transport.
1. A packaging unit, which comprises:
a first section including a removable sample analysis slide;
a second section including a removable sample collection device, wherein the removable sample analysis slide includes a location into which the removable sample collection device can be inserted;
a thermoformed well formed in a bottom of the second section adjacent to a splash wall, wherein said splash wall is located between the first section and the second section; and
an overflow reservoir located in the bottom of the second section and in fluidic communication with the thermoformed well.
2. The packaging unit as recited in claim 1 , further comprising:
at least one snap-in projection formed in a side wall of the first section designed to hold the removable sample analysis slide securely in place, and
at least one snap-in projection formed in a side wall of the second section designed to hold the removable sample collection device securely in place.
3. The packaging unit as recited in claim 2 , in which the packaging unit is constructed from a plastic selected from one or more of the following:
acrylonitrile-butadiene-styrene, high-density polyethylene, high impact polystyrene, glycolized polyethylene terephthalate, polycarbonates, polypropylene, and acrylic sheets.
4. The packaging unit as recited in claim 1 , further comprising a perforation for separating the first and second sections.
5. A method of using a packaging unit as recited in claim 1 , to prepare a collected sample for analysis which comprises:
removing the removable sample analysis slide from the packaging unit;
obtaining a sample in a pipette or syringe;
transferring at least a portion of the sample in a pipette or syringe to the thermoformed well of the packaging unit, thereby obtaining a transferred sample;
obtaining a collected sample by allowing adequate time for at least part of the transferred sample to be acquired by capillary action into the removable sample collection device;
removing the removable sample collection device containing the collected sample from the packaging unit; and
sliding the removable sample collection device containing the collected sample into the removable sample analysis slide, thereby forming a combined unit suitable for further analysis.
6. The method as claimed in claim 5 , wherein the step of removing the removable sample analysis slide from the packaging unit is performed any time before the step of sliding the removable sample collection device containing the collected sample into the removable sample analysis slide thereby forming a combined unit suitable for further analysis.
7. The method as claimed in claim 5 , wherein about ½ milliliter of sample is transferred from the pipette or syringe into the thermoformed well.
8. The method as claimed in claim 5 , further comprising a perforation for separating the first and section and wherein the first and second sections are separated at the perforation before the step of transferring at least a portion of the sample in a pipette or syringe to the thermoformed well.
9. The method as claimed in claim 8 , wherein the step of removing the removable sample analysis slide from the packaging unit is performed any time before the step of sliding the removable sample collection device containing the collected sample into the removable sample analysis slide, thereby forming a combined unit suitable for further analysis.
10. The method as claimed in claim 8 , wherein the sample is a finger stick of blood.
11. A method of using a packaging unit as recited in claim 1 , to prepare a collected sample for analysis which comprises:
removing the removable sample analysis slide from the packaging unit;
removing the removable sample collection device from the packaging unit;
gaining access to a sample;
placing the removable sample collection device in fluidic communication with the sample;
obtaining a collected sample by allowing adequate time for at least part of the sample to be acquired by capillary action into the removable sample collection device; and
sliding the removable sample collection device containing the collected sample into the removable sample analysis slide, thereby forming a combined unit suitable for further analysis.
