Abstract

The vein holder has an upright wall forming a central opening. The central opening is large enough to allow easy access by a needle. A bottom flange extends outwardly from the wall and rests against the patient's skin. It is the bottom surface of the flange 14 which holds the skin tight to prevent movement of the vein relative to the skin. In addition, pressure applied by the vein holder closes the vein at an end away from the syringe opening.

Description

VEIN HOLDER

BACKGROUND OF THE INVENTION

[0001] Medical procedures often require the use of a needle and syringe for the injection of medicine into a patient or the collection of a blood sample. Often these procedures require the needle to directly access a vein or artery. The ease in doing so depends on the skill and experience of the health provider, the accessability of the patient's veins and whether the patient is prone to move during the procedure.

[0002] Devices have been developed to help the health care provider in accurately placing a needle and syringe. One such device is disclosed in U.S. 5,911,707 (Wolvek et al . ) , disclosing a needle guide having a body with fingers extending therefrom to create openings at either end. Support members 30, 32 facilitate insertion of a needle. Also, U.S. 4,314,568 (Loving) discloses a vascular stabilizer having a flat body with a central slot 18. [0003] In patients where access to veins is difficult, health providers sometimes resort to using a tourniquet in order to make the veins more pronounced and easier to access. In older patients this may cause veins to rupture due to high back pressure caused by the tourniquet. Another problem with older patients is a tendency of the veins to move, making the accurate placement of a needle more difficult.

[0004] It is an object of the invention to provide a vein holder allowing for the easy access of a vein by a needle. [0005] It is another object of the invention to provide a vein holder stretching the skin to stabilize the position of the vein relative to the skin.

[0006] It is yet another object of the invention to provide a vein holder which does not utilize a tourniquet. It is still another object of the invention to provide a vein holder which may be held in place by one hand.

[0007] These an other objects of the invention will become apparent to one of ordinary skill in the art after reading the disclosure of the invention. SUMMARY OF THE INVENTION

[0008] The vein holder has an upright wall forming a central opening. The central opening is large enough to allow easy access by a needle. A bottom flange extends outwardly from the wall and rests against the patient's skin. It is the bottom surface of the flange 14 which holds the skin tight to prevent movement of the vein relative to the skin. In addition, pressure applied by the vein holder closes the vein at an end away from the syringe opening.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 is a perspective view of the vein holder;

[0010] Figure 2 is a top view of the vein holder; and

[0011] Figure 3 is a cross-sectional view along 3-3 of Figure 2.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Figure 1 shows the vein holder 10 having the upstanding wall 12 forming a central opening. The upstanding wall may be any shape as long as a central opening is formed. In Figure 1 the upstanding wall has an arcuate shape allowing for the more comfortable grip by a health provider with one hand. [0013] A bottom flange 14 extends outwardly from the wall 12. The bottom flange will be discussed in further detail below. The end 16 of the upstanding wall have a gradually decreasing height so that the top edge of the wall 12 transitions into the side edge of the bottom flange 14.

[0014] Figure 2 depicts a top view of the vein holder. In this view, the C-shape of the vein holder is clearly depicted. The central opening formed by the wall 12 and the space between the end 16 provides the health care provider ample room to both locate a vein and access the vein with a needle and syringe. [0015] Figure 3 shows a cross-sectional view along line 3-3 of Figure 2. In this view, the bottom surface of the flange 14 is seen. The bottom surface of the flange contacts the skin and serves to both hold the skin within the central opening tight and apply pressure to close the vein to the access. Ideally, the vein will be closed by a portion of the bottom flange which is opposite the space between the end 16 giving the health care provider the best possible view and room in order to access the vein.

[0016] The vein holder can be held by one hand, freeing the health care provider' s other hand to manipulate the needle and syringe. The vein holder simultaneously the skin tight to prevent movement of the vein relative to the skin and applies pressure to close the vein to make the vein easier to access. [0017] While the invention has been described with reference to preferred embodiment, a variation to modifications would be apparent to one of ordinary skill in the art. The invention encompasses such variations and modifications.

Claims

What is claimed is :

1. A vein holder comprising an upwardly extending wall having a top surface, a bottom surface, a first end and a second end, said upwardly extending wall forming a central opening, and a space between the first end and the second end allowing access to the central opening.

2. The vein holder for claim 1, wherein said upwardly extending wall is arcuate.

3. The vein holder of claim 1, wherein said upwardly extending wall is C-shaped.

4. The vein holder of claim 1, wherein the bottom surface of the upwardly extending wall is formed by an outwardly extending flange.

5. The vein holder of claim 1, wherein the ends .of the upwardly extending wall have a gradually decreasing height.

6. A vein holder comprising an upwardly extending wall, an outwardly extending bottom flange, the wall forming a central opening and having a pair of ends spaced from one another to create an access opening to said central opening.
