RU159072U1 - UNIVERSAL SYRINGE - Google Patents

Abstract

A universal syringe, which is a syringe for one hand, having an additional stop on the side of the rod, rigidly attached to the body of the syringe with two racks, characterized in that each of the racks of the additional stop near the base has transverse cuts.

Description

UNIVERSAL SYRINGE

The claimed technical solution can be used in the field of medicine.

Known designs [1] medical syringes (Fig. 1), which contain a hollow body-cylinder (1) with flat palm rests (4) and a piston (2), moved inside the body by means of a rod (3) with a stop (5) .

The disadvantage of these devices is that the syringe is filled with two hands: one syringe is held by the body, and the other extends the piston rod.

Also known is the design [2] of a syringe for one hand (Fig. 2), which has an additional stop (14) on the side of the rod, rigidly attached to the body of the syringe with two racks (13), which allows both emptying and filling the syringe with liquid forces only the flexor muscles of the fingers of one hand.

The disadvantage of this device is that the additional emphasis can create some inconvenience when working with a syringe with two hands.

The task to which the claimed technical solution is directed is to provide the ability to quickly remove additional emphasis when such a need arises.

The problem is solved due to the fact that the design of the syringe for one arm, which has an additional stop (14) fixed relative to the body on the side of the rod (9), has the following difference: each of the posts (13) of the additional stop near the base has two transverse cuts ( 15) located in one plane (Fig. 3).

The technical result of using the utility model is the ability to quickly remove additional emphasis by breaking off the incisions and, thus, turning the syringe for one hand into a regular medical syringe.

The technical nature and principle of the utility model is illustrated by drawings, which depict:

The ability to implement the claimed utility model is shown by the following examples:

An additional stop (14) is connected to the body of the syringe by two rigid struts (13) so that between it and the stop of the rod (11), extended to the maximum volume, there will be a gap sufficient to accommodate the thumb or index finger (Fig. 2, 3) . Moreover, the thickness of the uprights in the plane of the additional stop is such that it does not create significant interference with the grip of the stem stop with two fingers of one hand. Each of the uprights (13) of the additional stop (14) near the base has two transverse cuts (15) located in the same plane. The jumpers between the notches are thin enough to easily break off the additional stop along with the posts if they create any interference with the manipulation of the syringe. At the same time, the strength of the struts operating on compression along the axis remains sufficient for fluid collection using an additional stop.

The claimed utility model is used as follows:

For fluid collection, the syringe (Fig. 3) is gripped by two fingers on the rod stop (11), and the third finger is placed on the outside of the additional stop (14). After that, the tip (12) or the needle worn on it is immersed in the liquid, which is drawn into the syringe due to the counter force of three fingers. The syringe is also emptied by the counter-force of three fingers, two of which cover the housing near the stops of the housing (10), and the third presses on the rod stop (11). If the use of an additional stop (14) is not necessary, it is removed by bending the uprights (13) until the jumpers break between the notches (15).
