DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device to facilitate the use of injection syringes for intramuscular and subcutaneous injections, especially in human- and veterinary medicine.
By such injections it is necessary to stretch the skin in the area of the injection, to make an almost painless perforation by the needle possible by driving the injection needle quickly through the skin, and to effect a distracting pressure or -pain, and especially to overcome at self-injection a psychological fear threshold for the sting of the injection needle.
It is known that the amount of pain of an injection depends to a great extent on the dexterity of the physician, the nurse, or in the case on self-injection of the dexterity of the respective person. This problem of the last case comes up especially with persons afflicted with diabetes, who require two or more insulin injections per day.
Up to this time no particularly simple devices for injection syringes have become known which facilitate considerably the injecting of medicines.
Therefore, an object of the invention is to provide a device which facilitates the above-mentioned procedures, and makes them safe for untrained people. Furthermore, this device should be easy to handle, and economical to manufacture, and combinable with conventional syringes without difficulty.
The above-mentioned objective is achieved according to the invention with a device of the type described in the beginning by providing that an essentially tubular sleeve, whose inner diameter is larger than the outer diameter of an associated injection syringe, has in its interior at least one clamping or holding element, which releases, when a certain pressure is reached, the forward motion of the syringe body with the needle which is disposed in the sleeve, whereby the length of the sleeve and the position of the clamping element in it are so dimensioned that the needle remains completely in the sleeve before the pressure is applied, and that after the application of the pressure the desired depth of injection outside of the sleeve can be reached.
In other words, the clamping element in the interior of the sleeve releases the body of the syringe with the injection needle when a certain pressure is exceeded which is applied onto it from the outside (top). Thereby, according to the invention the length of the sleeve and the distance of the clamping element from the lower sleeve edge are so dimensioned that the injection needle lies completely in the sleeve, and after the release of the injection syringe by the clamping element and by its forward motion the injection needle emerges from the sleeve.
The advantages which can be achieved by the invention are especially the following points: self-injections and in situations where only one hand can be used, and rapid application of the injection needle. needle is not visible, which reduces the fear of the needle, and thereby makes it easier for the physician to prescribe the self-injection, on the point where the needle enters and expands or otherwise affect this spot, conventional protection tube for the injection needle, and thereby reduce the manufacturing cost.
In the following the invention will be further explained with the aid of a sample embodiment, from which further advantages and features of the invention can be learned. There are shown:
FIG. 1: a perspective view of an embodiment according to the invention;
FIG. 2: a section through the embodiment shown in FIG. 1;
FIG. 3: an embodiment of the invention which is a slight variation compared to FIG. 1;
FIGS. 4a to 4e: shows schematically the phases during the injection procedure, whereby the injection syringe is shown in its positions inside of the device during the various phases of the injection procedure;
FIG. 5: a device integrated with the injection syringe according to the invention;
FIG. 6: another embodiment of the device according to the invention; and
FIG. 7: a perspective view of a further developed form of the invention provided with a slanted edge of the sleeve.
FIG. 1 shows a perspective view
