Description

Field of Invention

The present invention relates to a hygienic connecting device for a needle and a mechanized hammer drill for micropigmentation and tattooing.

BACKGROUND OF THE INVENTION

Currently, for operations such as micropigmentation and tattooing, needles with one or more tips are used, which can be replaced with a mechanized hammer drill, which includes a pencil-shaped body for better grip, with an internal electric motor and a transmission element to which there is access from the outside, to which the needle is attached and which provides micro-movement of the sleeve in the axial direction, which causes the introduction of pigment under the skin when it is prok lyvanii.

The transmission element to which the needle is attached consists of a rod that passes through the housing through an opening intended for this purpose, and into which the needle is inserted or screwed into via its own hollow end.

These configurations have two main drawbacks, because, on the one hand, the simple insertion connection, which is most widely used, often leads to undesired needle detachment, and, on the other hand, both insertion and threaded configurations can easily cause the reverse flow of pigment and other fluids, sometimes emitted by the body, of fluids due to punctures made by a needle, in the direction of the internal space of the perforator body through the hole through which the transmission passes th element, which is a problem from the viewpoint of hygiene and can even cause damage.

This is a major drawback of modern connecting devices, because although disposable needles are currently available, this does not prevent the interior of the housing from being contaminated by the passage of fluids, and pollution is still less possible with reused needles which must be sterilized in an autoclave, the use of which may be called into question by patients.

From US patent document 20020094229 of July 18, 2002, a device for a needle and a mechanized hammer drill is known, comprising a threaded rod configured to shuttle a sleeve protruding from a mechanized hammer drill body to which the needle base is attached.

Achievable technical result of the claimed invention consists in reducing the reverse flow of body fluids.

Description of the invention

The connecting device in accordance with the invention serves to attach the micropigmentation needle and / or tattoo to a mechanized hammer drill, which ensures that the sleeve moves under optimal sanitary conditions, since it prevents the penetration of pigments or body fluids that are released when pigments are applied into the inner space of the hammer drill case and pollution of its internal space or damage to its internal mechanisms.

In accordance with the invention, the connecting device consists of a threaded rod that protrudes from the body of the mechanized hammer drill through an opening designed for this purpose, and the base of the needle, which is attached to the specified rod so that it cannot be disconnected by unscrewing.

The rod is mechanically connected to the electric motor, which provides the shuttle axial movement of the rod, and protrudes from the housing through an opening that is located in its extension part and / or sleeve protruding from the housing having a cylindrical shape, the rod extending centrally through the end of the housing.

On the other hand, the base of the needle consists of a body, ideally made of plastic and having a disc-shaped shape, the edges of which extend in the axial direction of the needle on both sides, forming a nest on one side, while on the same side of the body from its end surface passes the central protruding part in which the non-detachable needle body is fixed, while on the opposite side of the body its elongated edge forms a mating overlapping hollow cylindrical part (skirt) around the extension part and / and and the sleeve body puncher, impaled on a lengthening portion and / or the sleeve body puncher. In the central part of one of the end surfaces, the disk-shaped body has a threaded hole for connection with the thread of the shaft of a mechanized hammer drill. The base of the needle has a protrusion on the outer peripheral surface for gripping the base with your fingers.

Thus, the threaded connection avoids accidental detachment of the rod from the base of the needle, while the socket interacts with the overlap provided by the fact that the hollow cylindrical part of the base of the needle covers the protruding extension of the body of the mechanized hammer drill, holds fluids and / or prevents their entry into the zone where the hole of the extension part of the punch body is located, through which the shaft passes, which prevents contamination of the internal space to rotary hammer drill.

Brief Description of the Drawings

Figure 1 - cross section of the cavity of the connecting device according to the invention,

figure 2 is a cross section of the base of the needle provided in the connecting device according to the invention,

figure 3 - threaded rod of the connecting device according to the invention.

Description of a variant of the practical implementation of the invention

The connecting device 1 in accordance with the invention consists of a threaded rod 2 emerging from a cylindrical sleeve 3, protruding from the body 4 of a mechanized hammer, which provides movement of the needle through a centered hole 5 at the end of the sleeve, and from the base 6 of the needle.

The rod 2 is screwed into the base 6 of the needle, which consists of a plastic case 7, essentially disk-shaped, which forms a protective element that prevents the direct penetration of fluids into the hole 5 of the sleeve 3.

On one of the end surfaces of the housing 7 there is a centrally located threaded hole 8, intended for connection with the rod 2, while the edges of the housing are elongated to form a hollow cylindrical part (skirt) 9, designed to fit on the sleeve 3 to ensure pairing with it.

On the opposite end surface, the housing 7 has a protrusion 9a located centrally and protruding from the housing 7, while the needle housing is fixed in the said protrusion without the possibility of disconnecting, while the edges 10 of the housing are elongated to form a socket that prevents diffusion of fluids in the direction of the end zone of the connection to the rod in cooperation with the hollow cylindrical part 9.

The outer peripheral part of the base 6 of the needle has a protrusion 11 extending axially to grip the base with your fingers and screw the base of the needle onto the shaft and / or unscrew the base of the needle from the shaft.

Despite the fact that the essence of the invention, as well as the variant of its practical implementation are described sufficiently, it should be noted that the details presented in the attached drawings can be changed without changing the basic principle.
