Embodiment 2

[0036] An injection needle in this embodiment includes an integrally connected injection end 1, a connecting end 2, and a pressing end 3, and the pressing end, the connecting end, and the injection end are sequentially connected; the pressing end is provided with a valve , only when the valve core 42 of the valve is pressed toward the injection end, the pressing end is in fluid communication with the external environment; when in use, the pressing end of the injection needle is sealed and matched to the front end of the matching syringe, and the matching installation During the process, the thimble on the matching syringe presses the valve core of the valve so that the syringe and the pressing end are in a state of communication, and the syringe can be operated for injection, and the injected liquid enters the pressing end, the connecting end and the injection end sequentially from the syringe.

[0037]The front end of the injection end is formed with a sharp part 12 that can b...

Abstract

The invention belongs to the technical field of injection, and discloses an injection needle, which includes an integrally connected injection end, a connecting end and a pressing end, and the pressing end, the connecting end and the injection end are connected in sequence; There is a valve, and only when the valve core of the valve is pressed toward the direction of the injection end, the pressing end is in fluid communication with the external environment; the front end of the injection end is formed with a sharp part that can be inserted into a tree, and the injection end The front end is also provided with at least one injection hole, and the injection hole is located at the rear side of the sharp part. The invention also discloses an injection method using the above-mentioned injection needle for injection. The injection needle of the invention is directly inserted into the tree for injection operation, which can minimize the wound of the tree and make it difficult for mold, bacteria and insects to enter.

Description

technical field [0001] The invention belongs to the technical field of injection, and in particular relates to an injection needle and an injection method thereof. Background technique [0002] At present, the degree of forest insect pests continues to increase, and forest insect control has become a hot spot in current research. Most of the existing technologies use simple instillation methods for trees and hanging needle drip methods to instill pesticides to prevent insect pests. Spraying pesticides to prevent insect pests is harmful to the environment. It is highly polluted and affected by wind and rain, so it is not recommended to use it. [0003] Simple instillation method for trees: use a puncher to punch a hole with a diameter of about 5 mm in the trunk and a depth of about 10 mm into the wood, insert the injection needle into the hole obliquely from top to bottom to the xylem, and connect the pesticide bottle to the xylem. On the injection needle, a free-falling inf...
