Abstract
Abstract A plant injection device is disclosed which comprises a narrow injection needle having a smooth outer surface, a variable high pressure system having a one-way output valve in the body of the device, and a fluid reservoir. The needle portion of the device may be inserted into the plant either by applying force to the body of the device or by drilling hole sized relative to the width of the needle in the plant and inserting the needle therein. The device allows a fluid to be injected into the tree within minutes at the optimum fluid pressure for the particular plant, thereby providing a single visit plant injection method. The high pressure acts upon the interior of the plant body to force the sides of the hole to contract about the outer surface of the needle thereby forming a pressure seal which prevents fluid from escaping around the needle.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
102 words
A novel method of injecting plant material comprising: injecting a needle into the plant material, placing pressurized fluid through said needle into said plant, the fluid under pressure initially being in an amount sufficient to create a force to seal the surrounding plant material and the outer wall of the needle together to seal the fluid under pressure placed into the plant material from escaping out of the plant material adjacent the outer wall of the needle, subsequently providing additional fluid under pressure to place additional fluid into the plant material, stopping additional fluid input through the needle into the plant material.
Claim 2
Dependent Claim
102 words
A novel method of injecting plant material comprising: injecting a needle into the plant material, placing pressurized fluid through said needle into said plant, the fluid under pressure initially being in an amount sufficient to create a force to seal the surrounding plant material and the outer wall of the needle together to seal the fluid under pressure placed into the plant material from escaping out of the plant material adjacent the outer wall of the needle, subsequently providing additional fluid under pressure to place additional fluid into the plant material, stopping additional fluid input through the needle into the plant material.
Claim 3
Dependent Claim
41 words
A novel method of injecting plant material as set forth in claim 1 wherein: said plant material is a living plant, said additional pressure automatically increases the force to seal the surrounding plant material and the outer wall of the needle.
Claim 4
Dependent Claim
41 words
A novel method of injecting plant material as set forth in claim 2 including: removal of the needle from the plant material after a reduction in the force to seal the surrounding plant material and the outer wall of the needle.
Claim 5
Dependent Claim
32 words
A novel method of injecting plant material as set forth in claim 3 wherein: said method provides the placing of a quantity of fluid into the plant material within a few minutes.
Claim 6
Dependent Claim
32 words
A novel method of injecting plant material as set forth in claim 1 wherein: said method provides the placing of a quantity of fluid into the plant material within a few minutes.
Claim 7
Dependent Claim
24 words
A novel method of injecting plant material as set forth in claim 5 wherein: said initial pressure being over 100 pounds per square inch.
Claim 8
Dependent Claim
24 words
A novel method of injecting plant material as set forth in claim 5 wherein: said initial pressure being over 150 pounds per square inch.
Claim 9
Dependent Claim
44 words
A novel method of injecting plant material as in claim 5 wherein: the subsequently provided additional fluid under pressure is provided at the optimum fluid pressure acceptance level of a particular type of plant to provide a fast injection of a quantity of fluid.
Claim 10
Dependent Claim
35 words
A novel method of injecting plant material as set forth in claim 1 wherein: the subsequently provided pressure is in the thousands of pounds per square inch to provide a single plant material contact method.
Claim 11
Dependent Claim
34 words
A novel method of injecting plant material as set forth in claim 1 wherein: the method is for palm trees, and the pressures of the fluids are from approximately 100-150 PSI to 2000-5000 PSI.
Claim 12
Dependent Claim
24 words
A novel method of injecting plant material as set forth in claim 3 wherein: the quantity of fluid is approximately 60 cc of liquid.
Claim 13
Dependent Claim
46 words
A novel method of injecting plant material as set forth in claim 1 wherein: the subsequently provided additional fluid under pressure is provided at the optimum fluid pressure acceptance level of a particular type of plant to provide a fast injection of a quantity of fluid.
Claim 14
Dependent Claim
27 words
A novel method of injecting plant material as set forth in claim 12 wherein: the needle includes a generally smooth outer surface that provides a sealing surface.
Claim 15
Dependent Claim
173 words
A plant fluid injection device including, a plant injection needle portion with a wall and a hollow interior portion, a body portion connected to said needle portion, a pumping portion connected to said body portion and said needle portion, said needle, body and pumping portions connected to one another and said pumping portion being at one end of said body, said needle being at the opposite end of said body portion, said body portion having a conduit therein with a fluid entrance, fluid exit and a pumping conduit portion, the improvement comprising: said body having a one way valve therein whereby inward movement of said pumping portion opens said valve to permit passage of fluid into said needle through the hollow interior portion and outwardly therefrom into a plant and provides a means to build up pressure at the distal end of the needle, said wall constructed to withstand an internal pressure in the thousands of pounds per square inch, said pumping portion providing thousands of pounds per square inch of fluid pressure.
Claim 16
Dependent Claim
173 words
A plant fluid injection device including, a plant injection needle portion with a wall and a hollow interior portion, a body portion connected to said needle portion, a pumping portion connected to said body portion and said needle portion, said needle, body and pumping portions connected to one another and said pumping portion being at one end of said body, said needle being at the opposite end of said body portion, said body portion having a conduit therein with a fluid entrance, fluid exit and a pumping conduit portion, the improvement comprising: said body having a one way valve therein whereby inward movement of said pumping portion opens said valve to permit passage of fluid into said needle through the hollow interior portion and outwardly therefrom into a plant and provides a means to build up pressure at the distal end of the needle, said wall constructed to withstand an internal pressure in the thousands of pounds per square inch, said pumping portion providing thousands of pounds per square inch of fluid pressure.
Claim 17
Dependent Claim
21 words
A plant fluid injection device as set forth in claim 6 including: said needle portion including a smooth outer sealing surface.
