Description

“An apparatus for the collection of samples for liquid based cytology tests” Introduction The invention relates to an apparatus for the collection of samples for liquid based 5 cytology tests and distribution thereof.

Background In one approach, cytology testing involves collecting a sample and transferring the sample to a slide at the sample collection site. The prepared slide is then sent to a laboratory for testing. Slides are relatively compact, inert and easy to pack and transport. In another approach liquid based cytology sample testing is used in place of slide based sample testing, ln liquid based cytology sample testing a collected sample is transferred immediately into a vial containing a preservative liquid and the vial containing the sample is sealed. The preservative liquid is often a methanol buffered liquid and there are standards and regulations relating to the carriage and transport of such flammable liquids. The main issues relate to the volumes of flammable liquids that can be transported via public carriage systems, to the types of containers required for the liquid, the methods of transport, and the temperature at which they are stored and transported. There are also issues relating to the transport of medical samples. In addition, it is often necessary that medical samples arrive at a laboratory for testing within certain time limits. As a result of the above the cost for carriage of the test materials and the samples is often prohibitive and the provision of testing services is often limited to large centralised sites.

Referring to Fig. 9 the main steps of the system of the invention are described.

The sample collection and shipping apparatus 1 is assembled at a distribution centre for 25 supply to a sample collection site. If, in general the sample collection sites handles only a few samples per day then a small sized sample collection and shipping apparatus 1 packed with small sized return shipment cartons 9 may be most appropriate. The sample collection site selects and orders a sample collection and shipping apparatus as required.

IE 07 0 9 25 -8The steps involved in the distribution of the sample collection apparatus, shipment of samples, collection and recycling of the components are as follows: I. Sample collection apparatus 1 is distributed to a sample collection site.

II. Cytology samples are collected at a sample collection site. A cytology sample collection device from the apparatus 1 is used to collect a sample which is transferred to a corresponding vial 3 containing cytology preservative liquid. A corresponding request form 7 is completed and the vial label 8 completed.

In the embodiment shown, the vials 3 are supplied with the labels 8 in place. However, it will be appreciated that the labels may be provided separately or integrally with the request form. If the label is provided separately then the completed label is attached to the vial.

HI. The items to be transported to a laboratory for processing namely, the vial containing the sample and the corresponding request form are packaged into a shipment carton 9 for shipment to one or more laboratories for processing. The sample containing vials are supported in the insert and the requisition or request form is placed in the carton which is then sealed.

IV. The carton is then transported to a laboratory by any suitable means.

V. At the laboratory, sample containing vials are removed from the carton for processing. The shipping components i.e. the cartons 9 and associated support means 13 and 14 are retained for collection.

VI. The used shipping components are collected from the laboratories and returned to a distribution centre. The cartons 9 and associated support means 13, 14 are recycled.

IE 0 70 9 25 -9The recycling process involves the steps of inspecting the components and replacing any damaged foam or cartons. Stickers 2] are applied to the carton 9 to cover previous carriage marks. Additional blank stickers may be used to cover any further marks on the carton.

VII. Sample collection apparatus 1 is assembled for distribution to a test site.

A distribution centre handles the supply to sample collection sites of the sample 10 collection apparatus. The sample collection sites and processing laboratories are independent entities and the samples are typically shipped between them by independent means. The apparatus 1 conforms to the requirements for shipping medical fluids, and so do samples shipped using the shipping components supplied with the sample collection and distribution apparatus.

The invention overcomes the problems of the prior art by providing means for the secure distribution of sample collection and shipping apparatus and shipment of collected liquid cytology samples from sample collection sites for processing. The system is flexible and takes account of the reality that different test sites handle different numbers of liquid cytology samples and therefore have different requirements.

The apparatus of the invention and the system for the distribution of the apparatus and shipment of collected samples answers the requirements of different sized GP (General Practitioner) surgeries where the number of liquid cytology samples collected may vary from day to day and where the overall number of samples collected may be limited.

The apparatus is also designed to cater for multiple laboratories. Each sample collection and shipping apparatus includes multiple shipping components and samples may be shipped from a sample collection site to multiple laboratories. The apparatus and the IE 0 70 9 25 -10components are acceptable for use across a wide range of sample collection sites and laboratories. The system provides excellent flexibility.

The medical user or GP is provided with all of the components required for collecting a liquid cytology sample and returning the sample in the apparatus. The components required for taking samples are sterilised and are retained in sterilised packaging until required for use. The kit is supplied complete with shipping components which conform with requirements and regulations for the shipment of medical samples and are appropriate for use by third party delivery firms. A sample collection site need not be concerned with the task of independently procuring packaging for shipping the liquid cytology samples.

Depending on requirements of the test site, it is possible to select tbe components to be included in a sample collection and shipping apparatus, with flexibility. For example, if only a limited number of liquid cytology samples are typically taken at a particular site then that site may be supplied with an apparatus having a greater number of small sized shipment cartons.

The composite apparatus of the invention has the additional advantages that it is easy to store and that all required elements are stored together as supplied in sterilised packaging. The apparatus is self contained and all the components required for taking samples and sending them to the laboratory are conveniently at hand for the medical user or GP.

The shipment cartons are sufficiently robust to enable recycling. Also the use of robust cartons better serves the requirements for secure support and handling of the liquid cytology sample containing vials.

The recycling process makes distribution highly economical. The system provides for ease in repackaging and facilitates multi-party distribution.
