ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a vein scope and injection system and for safely and efficiently locating veins to thereby provide precise venous access.
2. Description of the Prior Art
The use of medical devices of known designs and configurations is known in the prior art. More specifically, medical devices of known designs and configurations previously devised and utilized for the purpose of increasing the safety and efficiency are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, United States Patent Number 4,613,328 to Boyd discloses a biomedical injector apparatus. U.S. Pat. No. 5,137,518 to Mersch discloses an instantaneous vein entry indicator for intravenous needle. Lastly, U.S. Pat. No. 5,030,207 to Mersch et al discloses an instantaneous vein entry indicator for intravenous needle.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a vein scope and injection system that allows for the safe and efficient locating of veins to thereby provide precise venous access.
In this respect, the vein scope and injection system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of safely and efficiently locating veins to thereby provide precise venous access.
Therefore, it can be appreciated that there exists a continuing need for a new and improved vein scope and injection system which can be used for safely and efficiently locating veins to thereby provide precise venous access. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in medical devices of known designs and configurations now present in the prior art, the present invention provides an improved vein scope and injection system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved vein scope and injection system which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a monitor assembly, a support assembly and a needle handling assembly. The monitor assembly includes an image viewing surface formed as a screen in an upper plane. The monitor assembly also includes an image receiving surface formed as a camera in a lower plane parallel with and beneath the upper plane. The monitor assembly also includes electronic components capable of producing an enlarged image upon the viewing screen of an area beneath the camera. The viewing screen is in a rectangular configuration with an upper edge and a lower edge and two parallel sided edges there between. The monitor assembly is formed with a first thickness. A support assembly is next provided. The support assembly includes a bracket portion and an arm receiving portion. The bracket portion is in a rectangular configuration with an upper edge and a lower edge and two parallel side edges there between to thereby form an upper surface and a lower surface. The bracket portion has a central opening located centrally with respect to the screen. The bracket and opening forms an enclosure for the receipt and secure containment of the monitor assembly within the opening. The bracket portion further has a plurality of axles coupled horizontally adjacent to the image receiving surface. The axles have a first end and a second end with the first end being coupled to the bracket portion and the second end being coupled to a roller. These rollers have a central aperture to receive the axle. The support assembly has a second thickness which is greater than the first thickness to thereby form a chamber between the edges of the bracket portion and beneath the camera. The arm receiving portion is of a generally U-shaped trough having an interior surface, a pair vertical side walls and a generally semicircular base region, thereby defining a region to receive an arm. The vertical side walls each have an angularly oriented track wherein a recess is nearly covered by an upper lip and lower lip. Together the roller and axle combination fit within the horizontal track of the arm receiver to allow the placement of the arm of a patient in a plane generally parallel with the plane of the camera. The band has exterior edges. Next provided is a needle handling assembly. The needle handling assembly includes spaced parallel guide rails coupled to the bracket portion adjacent to the lower face and extending away from the bracket portion. The needle handling assembly also includes a slide member with laterally spaced apertures for being slidably received on the rails and with a central aperture. Lastly, a syringe is removably positioned within the central aperture of the slide member. The syringe has a needle extending into the chamber so that the tip of the needle is located within the chamber to allow the movement of the syringe and needle and slide member along the rails for advancement of the needle toward and into a vein during the enlarged viewing of the needle and an appropriate vein of a patient. In this manner precise viewing and venous access is facilitated during operation and use.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved vein scope and injection system which has all of the advantages of the prior art medical devices of known designs and configurations and none of the disadvantages.
It is another object of the present invention to provide a new and improved vein scope and injection system which may be easily and efficiently manufactured and marketed.
It is further object of the present invention to provide a new and improved vein scope and injection system which is of durable and reliable constructions.
An even further object of the present invention is to provide a new and improved vein scope and injection system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such vein scope and injection system economically available to the buying public.
Even still another object of the present invention is to provide a vein scope and injection system for safely and efficiently loca
