Description

[0001] The present invention relates to a wood injection needle and a wood injector kit,

The present invention relates to an intravenous needle and an intervening syringe kit, and more particularly to an intermittent syringe kit in which an injection needle for administering an agent to the body of a plant and the related parts are additionally included.

Interjection is a useful method for administering therapeutic agents and prophylactic agents to plants, especially trees, or to hydrate transplanted trees.

However, since the conventional in-situ scanning method requires a space for mounting the injector, it is necessary to perform a drilling operation with a drill. The drilling operation to remove some parts is invasive and requires a lot of labor.

In addition, conventional screening methods using an interlabial injector have been limited to the winter between December and February due to the secretion of the pine juice. In addition, the conventional injector and the subsequent interjection method have been applied to the topographic characteristics , The influence of the thickened brush after the spring, and the complexity of the equipment.

EP0761399 discloses a configuration relating to valves and injection guns which enable leakage prevention and re-injection to be carried out, which emphasizes that continuous injection and repeated injection of the drug are required.

U.S. Patent No. 5,478,394 discloses an injector with an unidirectional valve that rests on a dispenser.

Korean Patent No. 10-1111056 discloses a pressure type water injector using power, and Korean Patent No. 10-1052492 discloses a pressure type water injection container. Injection devices of the pressure-based dosing method are generally complicated in the structure of the device, and there are problems in that the weight is increased to a considerable extent due to a large number of incidental parts. Although several syringes have been known to apply injection pressure to the inside or the outside of a container by applying elastic spring kind thereto, there is a problem that the pierced syringe is closed because the syringe is not a direct type.

Known injectors require a number of puncture spaces as pre-conditions for the execution of the inter-scan method. Perforating work to remove some parts is invasive and requires more labor.

Korean Patent No. 10-1288930 discloses a type of intravenous syringe. Although the use of a trocar is an attempt to exclude the removal of the woody part using a drill, there is a limit to the lack of coping with the closure of the trocar.
