Needle length regulating device for bleeding needle tube

Abstract

The invention relates to a device for adjusting the length of a bleeding needle tube. A lower cover having an opening is thread-engaged at the lower side of the tube body. The length adjusting device is arranged inside the needle body, consisting of a blood feeding material inserted to the lower side of an impact material and a needle length adjusting area thread-engaged with the blood feeding material. A reinforcing bone is arranged above the blood feeding material. An exciting heave is arranged above the reinforcing bone while a helix part is arranged below the reinforcing bone. A blood feeding needle is arranged below the helix part. A fixing body of the needle is thread-engaged with the needle length adjusting area so that the operator can observe through eyes at the same time adjust the length of the needle simply and conveniently according to the selective operation of the needle adjusting area. Besides, the length of the needle can be adjust by arranging the fixing body of the needle on a blood feeding tube which has no function of adjusting the length of the needle so as to expand the application scope of the invention. The invention implements the strong and weak excitations on skins selectively by arranging exciting heaves with different models at the upper end and the lower end of the fixing body of the needle, thereby doubly increasing the excitation effect.

Description

technical field [0001] The invention relates to a bleeding needle tube, through which first aid measures can be taken, and secondly, it has the curative effect of recovery and fatigue prevention by stimulating the skin. More specifically, it relates to a needle length adjusting device for a bleeding needle tube. The needle fixing body is connected by the helical connection of the hemorrhage material with stimulating effect and the needle length adjustment area, so that the operation of adjusting the needle length can be performed while observing with the naked eye. Moreover, the needle fixing body can be installed on the ordinary bleeding needle tube without the needle length adjustment function, so as to implement weak and strong stimulation to the skin. Background technique [0002] Like conventional bleeding needles, the inventors have successfully submitted applications for "No. 2000-2481" and "No. 2000-15243" utility models. It is the feature of the invention that the...

Problems solved by technology

But, because the size of above-mentioned needle protection area is extremely small, not only easily lost, and the operation of reinserting bleeding needle in needle protection area after finishing the bleeding operation is cumbersome and very unhygienic.

[0011] Third, the stimulating protrusions are non-selective in stimulating the skin, and can only stimulate the skin through one intensity, thus reducing its stimulating effect
