Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Example 1
Referring to fig. 1, a disposable endoscopic injection needle is shown, wherein a dosage control device 4 is mounted on a needle body 1.
The injection needle body 1 comprises a front handle assembly 5 and a rear handle assembly 6, wherein the front handle assembly 5 comprises an outer tube 7, an infusion inner tube 8 is arranged in the outer tube 7, and a needle head 2 is arranged on the infusion inner tube 8; the rear handle assembly 6 comprises a handle 9, an inner tube 10 is arranged in the handle 9, a rubber plug 15 is arranged in the inner tube 10, and the rubber plug 15 is connected with a core bar 11; the handle 9 is clamped with the outer tube 7, and the inner tube 10 is communicated with the inner infusion tube 8.
The dosage control device 4 comprises a sleeve 12 arranged on the handle 9, 10 fixed rubber bumps 13 are uniformly distributed in the sleeve 12, a movable rubber bump 14 is arranged on the core bar 11, the sum of the lengths of the fixed rubber bumps 13 and the movable rubber bumps is slightly larger than the diameter of the sleeve 12, when the rubber plug 15 is pushed to the end, the movable rubber bumps on the core bar are at the initial position and are pulled outwards by the core bar along with the rubber plug, so that the injection needle sucks injection, and when the movable rubber bumps on the core bar are contacted with the fixed rubber bumps on the sleeve once, the injection needle absorbs 0.5 ml more injection, so that the injection is conveniently controlled, and doctors can visually control the state of an illness of a patient and control dosage.
Install guide head 3 on syringe needle 2, guide head 3 is hollow stainless steel structure, and the anterior segment is the hemisphere, and the middle part is cyclic annular, and the end is ring shape.
The disposable endoscope injection needle has the characteristics of simple structure, convenience in dosage control and convenience in operation.
