Summary for Patent: 9,192,361
Title:Fecal microbiome transplant material preparation method and apparatus
Abstract: This invention relates to a fecal microbiome transplant material preparation method and apparatus for the preparation of fecal material for a fecal transplant. A healthy patient\'s stool is collected and deposited in a first container which has its open end attached to a second container to form a fecal processing device. Blender blades are positioned in the second container and a filter is mounted therein. Liquid is injected into the second container through a syringe port having a valve therein to block the escape of liquid from the connected containers. Intake and exhaust ports allow air to enter and escape from the connected containers while blocking the escape of liquid. The liquid and fecal matter in the connected containers is blended and the blended liquid is strained through the filter in the second container and removed through the syringe port for use in a fecal transplant.

Application Number:13/776,844
Patent Claims:1. A method for the preparation of fecal material for a fecal transplant comprising the steps of: obtaining a fecal processing apparatus having a fecal collection container having an open end and a fecal processing container having an open end, said fecal processing container having a filter therein and having a syringe port in the side thereof for the injection of and removal of materials, said syringe port having a check valve therein to prevent the escape of liquids therethrough from said fecal processing container; depositing fecal matter from a patient into said fecal collection container; attaching the open end of said fecal collection container having fecal matter therein to the open end of the fecal processing container; injecting a dilutant liquid through the syringe port into said connected fecal processing container and fecal collection container; blending said injected liquid and collected fecal matter in said connected fecal collection container and fecal processing container and separating solid materials from passing through said fecal processing container filter; draining said blended liquid material through said fecal processing container filter into said fecal processing container; and removing material from said fecal processing container through said syringe port for use in a fecal transplant; whereby fecal material is collected and processed for use in a fecal transplant.

2. The method for the preparation of fecal material for a fecal transplant in accordance with claim 1 in which the step of obtaining a fecal processing apparatus includes a fecal processing container having blending blades therein.

3. The method for the preparation of fecal material for a fecal transplant in accordance with claim 2 in which the step of injecting a fluid into said processing apparatus includes injecting sterile water.

4. The method for the preparation of fecal material for a fecal transplant in accordance with claim 3 in which blending includes shaking the attached fecal collection container and fecal processing container to blend the materials therein passing through said blending blades.

5. The method for the preparation of fecal material for a fecal transplant in accordance with claim 4 in which the step of draining includes resting the fecal processing container below the attached fecal collection container to allow drainage into the fecal processing container through said filter.

6. The method for the preparation of fecal material for a fecal transplant in accordance with claim 5 in which the step of obtaining a fecal processing apparatus includes obtaining a fecal processing container having an air exhaust port having a filter and a check valve therein through the side thereof to allow air to escape therefrom when injecting liquids into said fecal processing apparatus.

7. The method for the preparation of fecal material for a fecal transplant in accordance with claim 6 in which the step of obtaining a fecal processing apparatus includes obtaining a fecal processing container having an air intake port having a check valve therein through the side thereof to allow air to be drawn into said container when removing liquids therefrom.

8. The method for the preparation of fecal material for a fecal transplant in accordance with claim 7 in which the step of obtaining a fecal processing apparatus includes obtaining a fecal processing container syringe port having an a tapered tube attached thereto, said tapered tube extending into the fecal processing container.

9. The method for the preparation of fecal material for a fecal transplant in accordance with claim 8 in which the step of obtaining a fecal processing apparatus includes obtaining a fecal processing container having a threaded surface around the open end thereof matching a threaded surface around the open end of the fecal collection container thereby allowing the containers to be threadedly connected together.

10. The method for the preparation of fecal material for a fecal transplant in accordance with claim 9 in which attaching the fecal processing container and the fecal collection container includes attaching a seal therebetween for forming an air and liquid tight seal therebetween.

11. The method for the preparation of fecal material for a fecal transplant in accordance with claim 1 including the step of injecting an inert gas into said fecal processing container.

12. The method for the preparation of fecal material for a fecal transplant in accordance with claim 11 in which said inert gas is nitrogen.

13. An apparatus for the preparation of fecal material for a fecal transplant comprising: a first container for the collection of fecal matter from a donor, said container having an open end; and a second container for processing the fecal matter collected in said first container, said second container having an open end, said first and second containers being removably attached together with their open ends abutting to form a generally airtight seal; said second container having blending blades and a filter therein and having a syringe port having a valve therein to allow the injection and the removal of a liquid therethrough with a syringe while preventing material from escaping therethrough when a syringe is not connected thereto, said second container having a gas outlet port in the side thereof having a valve therein to allow gas to escape from said connected first and second attached containers when material is being added to said second container, said second container having an air inlet port having a valve therein to allow air into said attached first and second containers when material is being removed therefrom through said syringe port while blocking fluid from escaping therethrough; whereby fecal matter collected in said first container attached to said second container can be processed for use in a fecal transplant.

14. The apparatus for the preparation of fecal material for a fecal transplant in accordance with claim 13 in which said first and second containers each has a threaded rim around the open ends thereof for attaching said containers together.

15. The apparatus for the preparation of fecal material for a fecal transplant in accordance with claim 14 in which a seal is mounted between said attached first and second containers.

16. The apparatus for the preparation of fecal material for a fecal transplant in accordance with claim 15 in which a tapered tube is attached to said syringe port for directing injected material into the bottom of said second container and for removing material from the bottom of said second container.

17. The apparatus for the preparation of fecal material for a fecal transplant in accordance with claim 16 in which the filter in said second container is a screen filter.
