Description

[0001] Syringe handling assist device [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary device used with a syringe, and more particularly to an auxiliary device for manipulating a syringe with improved structure so that a syringe can be smoothly operated even with one hand.

As the use of ultrasound devices in the medical field increases, many procedures are performed after confirming the anatomical structure directly with ultrasound.

Typically, when injecting a drug using a syringe on a muscle or joint, or when obtaining a tissue using a syringe when a suspected cyst or cancer is suspected, the patient is directly sono-guided using the opposite hand, Inject or take tissue.

Ultimately, according to this procedure, since the syringe must be manipulated with the other hand while holding the ultrasonic wave with one hand, a smooth tissue collection can not be expected.

In order to overcome such disadvantages, the prior art disclosed in Korean Patent Registration No. 10-1328443 has been proposed as a prior art. However, this prior art merely provides a stable support for the auxiliary device of the syringe by merely fitting the syringe to the auxiliary device It has a disadvantage in that it has a complicated structure due to an unnecessary structure such as not being able to be implemented and an adsorption means other than a syringe being provided, resulting in poor efficiency of use.

The prior art disclosed in U.S. Patent Application Publication No. US 2015/0174326 A1 also provides a solid support for the syringe auxiliary device but requires a separate connection mechanism for connecting the pusher of the syringe to the delivery screw As a result, the efficiency of coupling and disconnection of the syringe to the auxiliary device is reduced.

Here, the finger support portion A means a portion protruding in the form of a flange so that a finger is hooked on the rear end (the needle is connected to the tip end) of the outer cylinder of the syringe.

The fixing member 10 is fixed to the fixing member 10 of the syringe so that the outer cylinder of the syringe is seated on the seating groove 12a and the finger support portion A of the syringe is fixed to the fitting groove 12b. Thereby enabling relative position fixation of the relative position.

7 and 8, the shifting member 20 is installed to be movable relative to the fixing member 10, and as shown in FIG. 4, the thumb member of the syringe B are fitted and fixed. Here, the thumb pressing portion (B) means a portion provided at the rear end of the plunger moving relative to the outer barrel and capable of pressing the plunger.

The power transmission means is for moving the movable member 20 relative to the fixed member 10 based on an electrical signal and includes a motor 32 and a plurality of gears 34 and 36 .

The auxiliary device for operating the syringe according to an embodiment of the present invention having such a configuration enables the syringe to be automatically operated by driving the motor 32 so that the syringe can be handled with one hand, The fixing groove 12a formed in the fixing member 10 and the fitting groove 12b formed in the fixing member 10 and the fixing groove 24a formed in the moving member 20 and the fixing groove 24b formed in the fixing member 10, As the design using the structure of the syringe itself is made, it is possible to increase the competitiveness of the product by reducing the manufacturing cost by simplifying the structure.

The auxiliary device for operating the syringe according to the present embodiment is configured such that the finger holding portion A and the thumb pressing portion B of the syringe are fixed to the fixing member 10 in a state in which the syringe is placed on the fixing member 10, The coupling between the fitting groove 12b of the moving member 20 and the fixing groove 24a of the moving member 20 can be engaged with each other, Let's do it.

3 and 5, the fixing member 10 employed in the present embodiment includes a main body portion 12 in which the seating groove 12a is formed, a main body portion 12 in which the main body portion 12 is formed, And a pair of guide rail portions 14 formed on both sides of the main body portion 12 and formed integrally with the main body portion 12.
