Embodiment 2

[0035] 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.

[0036]The front end of the injection end is molded with a sharp part 12 that can b...

Abstract

The invention belongs to the technical field of injection, and discloses an injection needle. The needle comprises an injection end, a connection end and a pressing end which are integrally connected,and the pressing end, the connecting end and the injection end are sequentially communicated; an inflating valve is arranged in a pressurizing end, only when a valve core of the inflating valve is pressed toward an injection end, the pressurizing end is communicated with outer environment fluid, a sharp portion inserting into a tree is formed on the front end of the injection end, the front end of the injection end is also provided with at least one injection hole, and the injection hole is located at the rear side of the sharp portion. The invention also discloses an injection method for injecting by using the above-mentioned injection needle. By directly inserting the injection needle into a tree for injection operation, the wound of the tree can be minimized, and the mold, bacteria andinsects do not easily 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...
