ITGE940145A1 - DEVICE FOR INSERTING AND/OR REMOVING THE NEEDLE - THE NEEDLE PROTECTION FROM THE SYRINGE, WITHOUT EVER HAVING MANUAL CONTACT WITH - Google Patents

Abstract

The device consists of two parts: a fixed A and a movable B, which has the possibility of sliding downwards if pressed, and of returning to the rest position, under the action of spring 7, if released; by inserting the syringe in the horizontal hole 3 and pressing the movable part B downwards, through the shaped profile 5, the protection from the needle is separated, which remains in the syringe ready for use. Inserting the syringe in the horizontal hole 2 and operating as in previously, the protected needle is separated from the syringe, so that they can be thrown separate, after use, in the appropriate containers.This occurs without ever touching the needle or its protection, but always and only the syringe and the device. - - ---- --- - - ----- ------ - ------ - -

Description

Description accompanying a patent application for an Industrial Utility Model, entitled "Manual or semi-automatic device for inserting or removing the needle in the syringe and / or its protection, without ever having physical contact with it, nor with its protection "

TEXT OF THE DESCRIPTION

The system consists of two parts:

a) cylindrical body A, made of sterilizable material with a shape as shown in FIG. 1 having two different diameters (approximately 60 mm. The smaller and 70 mm the larger), and crossed in the smaller diameter part, by two overlapping holes (2, ^), made horizontally, of the same diameter as the needle protection (FIG. 2)

b) hollow cylindrical body B (also made of sterilizable material) in the shape of an inverted cup with a rectangular slot (5) located in the lower part and made as per drawing (FIG. 3)

This body B is positioned upside down on the body A described above, after having internally interposed a vertical contrast spring (7) (FIG. 6), in the seat (f). The body B can therefore slide vertically (upwards and downwards) but cannot rotate, due to a vertical guide (6), made between the two bodies (FIG. 3). This guide (6) is easily removable, to also allow the sterilization of the individual parts of the device, which can be sterilized, not disassembled, in an autoclave.

The action of the user on the device is only to insert the syringe into the horizontal hole (2 or 3) and to press downwards, or to release the upper body B when you want the spring (7) to return it to the rest position.

In FIG. 4 illustrates the various phases of how to make the syringe ready for use:

- insert the syringe with protected needle in the lower horizontal hole 3 (phase a)

- body B is pressed downwards (phase b 1

- yes extract the syringe keeping the body B pressed (phase c) (the protection remained in the device)

- body B is released: the spring (7) brings it back to rest position (phase d)

To replace the protection, if necessary, simply insert the needle into hole 3, hold the device still, press the syringe lightly into the protection, and extract the syringe with the protected needle.

In FIG. 5 shows how to separate the needle together with its protection from the syringe:

- the syringe with protected needle is inserted into the upper horizontal hole 2 (phase a)

- the body B is pressed downwards until it stops (phase b j

- the syringe is removed: needle and protection are in the device (phase c)

- body B is released: the spring (7) brings it back to rest position (phase d)

To reinsert the needle into the syringe, simply insert the syringe into hole 2 and press lightly, holding the device still

To throw the needle (together with its protection) it is sufficient to tilt the device, by about 45 degrees, with respect to its vertical axis, with the holes (2 and 3) facing the collection box. In the case of the model with suction cup and expulsion spring, the last phase described takes place automatically

Claims (2)

CLAIMS 1) Device (fig. 6) which provides for the relative movement of two shaped bodies A and B (fig. T, 3) by virtue of the sole action of force acting vertically (supplied manually or by pneumatic automatism), which allows the manipulation of both the needle and protection, without ever having contact with the needle or with the protection, to the benefit of the operator's safety from accidental punctures, with the guarantee that the sterile needle does not come into contact with anything, before its use. 2) Device as per claim 1, characterized by an internal spring (7), which returns the device to the rest position, in the absence of drives 3) Device as per claim 1, which has horizontal holes (2, 3) for selecting "PROTECTION EXTRACTION" (3) and "PROTECTED NEEDLE EXTRACTION" (2) located in superimposed position for immediate and precise identification of the operation that will be carried out. (fig. 1, 2) 4) Device as per claim 1, with the holes positioned as per claim 3, which allow to use the device in a fixed front position, with respect to the operator, possibly being possible to fix it to the work surface by means of a suction cup (position them in the lower hollow part (4) of body A), or to a rigid structure, equipped with a pneumatic actuator. 5) Device as per claim 1, having a threaded hole (8) in the upper part of the body B, which allows the application of a mushroom-shaped element (9) to facilitate the action of downward pressure or insertion of the end part of the rod of a pneumatically operated cylinder (10) to realize the automated movement of the device. 6) in the device, as per claim 1, in the case of use of the suction cup, it is also foreseen the possibility of mounting a spring system, which realizes the automatic ejection of the protected needle
