Description

Universal support for hypodermic needles.

The present invention relates to a support, intended for holding all types of hypodermic needles, when as with three-way valves, these being necessary in the most varied surgical processes, and that has the peculiarity of attaching to the needle used by means of a simple pressure adaptation process, which will allow it way the incorporation of said valves when they are required, and which, subsequently, is fixed to the skin by adhesive along its perimeter, which provides maximum stability and guarantees the comfort and tranquility of the user. Given the ease with which devices for administration of medications and similar substances may remain out of place or area of application, and due to this, to a large extent, to sudden, voluntary and involuntary movements, on the part of the interested party or of those who attend it, or also due to transfers of the affected person, or even, to mere manipulation or improper application thereof, not to mention the effects counterproductive in the treatments and care of patients That this may entail. In addition, various can be produced lesions produced on the skin given the sharp nature of the most of the needles used, the use was evident of some mechanism that solved these setbacks, something that Achieve with this simple support. He neutralizes the discomforts and setbacks that cannot be avoided with employment and use of the aforementioned conventional needles and valves.

It is obvious that the purpose of the government public institutions related to this issue, it should consist of having up to date medical equipment essential for public health institutions to attend population health problems, so, in addition to update and ensure that the instruments and medical equipment of the dependencies and entities that provide health services, are properly in the best possible conditions, it becomes clear which at the same time incorporate the instruments and medical equipment that represent greater specificity and security, and that modify those who advance in knowledge and technological development have shown as widely surpassed, to be considered completely insufficient.

With the invention proposed here it has been achieved in fact, create an accessible and extremely simple device that solve the inconveniences of all other mechanisms similar already existing, providing greater security and comfort by middle of its novel but simple features. What allows, in addition to obtaining maximum performance and savings through of cost reduction, the greatest use of spaces and available structures, the efficiency in the administration of time spent on treatments and also the ease and practicality when carrying out the transfer and / or the handling of patients when necessary to apply them permanently a fixed needle that is not removed for a period considerable.

The patent object of this invention has its field of application in the medicine industry, the pharmaceutical, including chemistry and related sectors, specifically in relation to hospitals, outpatients, laboratories, health centers, transfusion centers and the like.

The state of the art presented in the news of several fastening systems, gadgets, supports, pistolitas and other type of mechanisms that are attached to instruments for the realization of certain procedures in the matter that we occupies, but none has managed to solve the inconvenience of instability of hypodermic needles and any valves

For example, items are known in the market as varied as passive safety devices, blood collection systems with rotating extraction, the physiological sample collection devices and procedures using the same, the extraction devices by pressure of body fluids from an incision, the fluid collecting devices, pressure rings matches for lancet devices and extraction systems blood, double safety spike needle sets for blood sampling, sample collection devices body fluid and cartridges containing the means of analysis used in such devices, fluid sampling biological and analyte measurement, lancet needles polygonal cross section or simple patches for micro hollow needles Also known are blood analyzers and puncture devices for use in blood tests, Retractable medical mechanism devices operated by caps, the Interstitial fluid extraction in patients for trials diagnostics, integrated lancets and fluid detectors body, safety devices and needle methods medical use, the traditional systems for the extraction of blood, those of test strip containers, the capacetes of adjustable limb for lancet devices, the vacuum-assisted lancet devices, in addition to improvements relating to skin punches, evacuation devices for blood collection tubes, the devices for skin incision in painless obtaining of small amounts of blood, those of blood collection that have a cannula, or the devices and methods to collect blood from an umbilical cord, or well, those for obtaining blood samples with a lancet holder anti-torsion, and devices for making liquid samples from a piece of flexible tube, between others. Despite being so numerous and varied teams available, the problem cited remains unresolved.

They are currently known in the state of the technique needles classified as painless, and multiple holes, medication injectors or regulating pistols e injectors, as well as certain types of needle protectors and of mechanisms that allow them to be disposed of more safely after of its use.

Over the years and with the advance of the science have been presented inventions aimed at improving all these systems and to regulate and magnify these processes, so the Document ES 2 192 707 presents a retractable needle holder and syringe, whose main feature is to present a needle with automatic retraction, desirable function when consider, above all, that after use, the syringes They can be dangerous for several reasons. There is a risk of injury with the needle itself, and there is a risk of disease transmission serious, such as Acquired Immune Deficiency Syndrome or AIDS. By this reason, the need to avoid the reuse of Syringes is widely recognized, goal achieved with this type of needles that does not remain inserted in the patient and that They must be immediately discarded.

Document ES 2 015 813 proposes another type of support designed particularly for injections or extractions, constituted by a support comprising a hollow body, preferably tubular, provided at one end of a fixed bottom or removable, from which a needle link element protrudes. He said link element is provided with breakage beginnings that They facilitate their separation from the bottom. In this way it is therefore possible,  After use, the immediate and easy separation of the needle linked to it in the support; it is true that the needles and used brackets, once divided in this way, can be collected in appropriate containers, but this does not change or not brings nothing to solve the problem caused by fixed needles  that remain connected to the user.

There are numerous additional cases such as those of Following documents, US Pat. No. 5,122,118 shows a syringe with an automatic retraction needle that includes a barrel that has an end of the needle, and an end of a plunger, a hole, and a plunger at the end of the plunger, this device involves the use of a jelly that would dissolve or would lose resistance in contact with the injection. It takes a relatively large amount of gelatin to form a capsule channel to accommodate the needle, and this and the characteristics of the material make it difficult to guarantee that it would work.

In addition the patents US A 5 049 133 and US A 5 188 614 show variants of complicated devices that are not considered totally effective and still not contributing absolute in the case of permanent needles.

However, until now, no one was known system, as simple as it may seem, that will end the discomfort and harm caused to patients who must follow a treatment with valves for a long time. The application of a practical system was not known either private areas or within the framework of public services. For the therefore, the known procedure, with which by means of a needle intravenously, the patient's vein is punctured and fixed This needle by adhesive to the patient's skin is revealed clearly insufficient given its ineffective support on the skin and for the various injuries that it could cause including the Own needle breakage.

Taking all these into consideration particularities, and analyzed the conjugate arguments, with the implementation of the universal support object of this patent, is given place to an end result in which aspects are contributed significant differentiators versus prior art current, and where a series of advances in the operations already known with their corresponding advantages. In particular:

-

With the Proposed procedure corrects the insufficiency of clamping, since that although the prick is practiced as in the method already known, the needle does not remain immobile only thanks to the applied adhesive.

-

Be prevents displacement and exit of the needle thanks to the compact of the block formed by the support and the needle with the valve, if This must be applied.

-

Be deflects the impact of eventual blows from the patient's skin towards the support itself without this impacting on efficiency and device permanence.

-

Be minimizes the appearance of bruises and other skin lesions given the abruptness and instability of the needle that pierces the skin of the patient and who previously depended on the utmost care to the time to manipulate and avoid aggressions by movement, the gravity, the inertia of the bodies, etc.

Thus, the invention is constituted from the following elements:

A piece of rectangular type, of material flexible, lightweight, hygienic and hypoallergenic or antiallergic, of smooth surface in its central part, and rough in its perimeter, presenting at one of its ends a longitudinal cut that covers a third of the support, its thickness being the same as that of a standard needle Towards the center of the support, united in solidarity with it and in the longitudinal direction are the clamping means for both the needle and valves three ways, the first one presenting a size and a shape appropriate to fit in it the area of union between the needle and the syringe. In turn, the clamping means for the three valves pathways are behind the needle clamp and are presented in the form of channels parallel to each other.

The support is fixed to the patient's skin by medium of an adhesive material. Then the needle is inserted into the fastening means present in the upper part of the support and in the cut, creating a compact block.
