Description

Double-control injector

Technical Field

The utility model relates to the technical field of syringes, especially, relate to a two accuse syringes.

Background

Syringes are a common medical device, and as early as the 15 th century, kathler, italian, proposed the principle of syringes, primarily for injecting liquid medicine or drawing fluids, and syringes that can also be used for medical devices, containers, scientific instruments such as those in chromatography, injecting gas through a rubber septum into a blood vessel would cause air embolism, and removing air from the syringe to avoid embolism consisted of inverting the syringe, tapping gently, and then squeezing out a little liquid before injection into the bloodstream.

The existing syringe cannot be easily used at a plurality of points:

(1) precise control of needle penetration depth

(2) Precise control of the amount of liquid medicine to be injected

Therefore, it is desirable to design a dual control syringe to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a double-control injector.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a double-control injector comprises a needle tube, wherein a solenoid is arranged at one end of the outer portion of the needle tube, a needle head is inserted into the top end of the needle tube, a push-pull rod is inserted into the needle tube, a positioning nut is connected to the outer portion of the push-pull rod in a threaded mode, and scales are arranged on the outer wall of one side of the positioning nut.

Further, solenoid and needle tubing are detachable construction, the screw thread is opened to one side inner wall of solenoid, the needle tubing passes through threaded connection with the solenoid.

Furthermore, one end of the push-pull rod is sleeved with a piston, and the piston is positioned inside the needle tube.

Furthermore, the needle tube also comprises an ear plate which is positioned at one end far away from the needle head.

Furthermore, one end of the push-pull rod is provided with a push-pull handle, and the push-pull handle is positioned at one end of the push-pull rod, which is far away from the piston.

The utility model has the advantages that:

1. the depth of the needle can be effectively controlled through the arranged solenoid, so that the depth of the needle can be accurately controlled; avoid the influence on the treatment effect caused by different penetration depths of the needles.

2. By the aid of the positioning nut and the scales, precise injection of the medicament can be achieved, and the injection amount of the medicament can be effectively controlled; especially, the micro-multi-point injection can avoid the influence on the treatment effect caused by inaccurate control of the injection dosage.
