Abstract
The utility model discloses a metal needle head for use in trunk transfusion. The metal needle head comprises a needle seat, a needle body and a needle point, wherein the needle body is fixed on the front end part of the needle seat; the needle point is positioned at the top end of the needle body; the needle seat comprises an interface end for being connected with a transfusion set and a needle body base; a bump is formed at the joint of the interface end and the needle body base; the side wall of the needle body is provided with an elliptical liquid outlet; the liquid outlet is positioned at one end close to the needle point. In the metal needle head, the liquid outlet is reasonable in design and is formed on the side wall of the needle body, so that the needle point can be inserted into a trunk easily, the liquid outlet is prevented from being blocked by wood chips during use, and successful input of nutrient solutions or liquid medicaments is ensured.
Description
Technical field
The utility model relates to a kind of metal infusion niidl processed of using to trees trunk injection plant nutrition liquid or medicament.
Background technology
Large tree transfusion is a kind of Novel garden treatment technology, and reason, as human transfusion, is all in order to supplement the nutrients, and to maintain normal metabolism, drug effect is direct, and environmental pollution is less.Nutrient solution contains the required nutrition of arboreal growth, can activate the cytoactive of large tree, and large tree growth activity material is provided, and as various trace elements such as multiple beneficial biological flora, organic peptide, boron, zinc, magnesium, iron, molybdenums, and is conducive to keep the skin wet to large tree.Liquid is directly inputted to trunk center by conduit, and trees are easy to absorb, and strengthen the restoring force of tree vigo(u)r.Meanwhile, in nutrient solution, contain sterilization component, can be large tree diseases prevention.Give trunk injection nutrient solution or medicament, become the important means of trees conserve, execute and be more conducive to fast repairing and supplement nutrition minute with traditional foliage-spray or plant roots, and can greatly reduce maintenance cost.
At present, mostly disposable infusion is used for to trunk transfusion method with syringe needle, this medical needle diameter is thinner, and the wood chip of xylem easily stops up syringe needle, has affected the effect of transfusion.
Utility model content
Technical problem to be solved in the utility model be to provide in a kind of simple in structure, use procedure be difficult for stopping up, the liquid syringe needle processed of the metal for trunk transfusion method of easy to leak not.
For solving the problems of the technologies described above, a kind of metal for trunk transfusion method of the utility model syringe needle processed, comprise needle stand, be fixed on the needle body of described needle stand leading section, and the needle point that is positioned at described needle body top, described needle stand comprises for connecting interface end and the needle body pedestal of transfusion device, the joint of described interface end and needle body pedestal forms projection, and described needle body sidewall is provided with oval-shaped liquid outlet, and described liquid outlet is positioned at the one end near needle point.
For further avoiding liquid outlet to be stopped up by wood chip, above-mentioned liquid outlet arranges along needle body length direction.
Preferably, above-mentioned liquid outlet is more than two.
Compared with prior art, the beneficial effects of the utility model are:
Liquid outlet of the present utility model is reasonable in design, and liquid outlet is arranged on the sidewall of needle body, is not only beneficial to needle point and inserts trunk, has also avoided liquid outlet in use procedure to be stopped up by wood chip, has guaranteed the smooth input of nutrient solution or liquid.Meanwhile, the utility model is metal material, long service life, and plug and play, simple to operation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of metal syringe needle processed for trunk transfusion method of the utility model.
Embodiment
As shown in Figure 1, a kind of metal for trunk transfusion method syringe needle processed, comprise needle stand 1, be fixed on the needle body 2 of described needle stand 1 leading section, and the needle point 4 that is positioned at described needle body 2 tops, described needle stand 1 comprises for connecting interface end 11 and the needle body pedestal 13 of transfusion device, the joint of described interface end 11 and needle body pedestal 13 forms projection 12, and described needle body 2 sidewalls are provided with oval-shaped liquid outlet 3, and described liquid outlet 3 is positioned at the one end near needle point 4.Described liquid outlet 3 is the groove arranging along needle body 2 length directions.Described liquid outlet 3 is more than two.
When infusing to trees, first the needle point of syringe needle 4 is hammered into trunk relevant position, make the major part of needle body 2 all enter tree body, the liquid outlet 3 that is located at needle body 2 sidewalls has entered the xylem of tree body, again interface end 11 and conventional infusion apparatus connector are matched, can start transfusion, nutrient solution or liquid are flowed out and enter xylem from liquid outlet 3 by syringe needle.While adopting the utility model to infuse to trees, avoid liquid outlet in use procedure to be stopped up by wood chip, guaranteed the smooth input of nutrient solution or liquid.
