APPARATUS FOR FACILITATING THE INSERTION OF A HYPODERMIC SYRINGE NEEDLE Filed April 23, 1964 I N VENTOR.
WILFRED W, WEESE1 BY $44M, $17M, AT'IORNEYS United States Patent 3,324,854 APPARATUS FOR FACILITATING THE INSER- TION OF A HYPODERMIC SYRINGE NEEDLE Wilfred W. Weese, Finishing, N.Y., assignor to Harry Swartz, New York, N.Y. Filed Apr. 23, 1964, Ser. No. 362,059 11 Claims. (Cl. 128-215) This invention relates to an apparatus for facilitating the insertion of a hypodermic syringe needle. In particular it relates to such a device which is designed to improve the ease with which material may be injected into or withdrawn from the vein of a human being.
Where it is desired to withdraw blood from the vein of a human being or inject medicinal substances into a vein, it is conventional to employ a hypodermic syringe. However, in utilizing such instruments, considerable difficulty is often encountered in causing a syringe needle point to properly penetrate a persons flesh so as to enter the interior of a vein.
The problems involved'in properly injecting a hypodermic needle point into a vein are widely known. While a variety of devices have been previously developed to facilitate the proper insertion of a hypodermic syringe needle into a vein, such devices have in general been characterized by substantial structural or operational defects.
One device heretofore sought to be employed comprises a spatula-like instrument which must be employed separately but in conjunction with a hypodermic syringe. A person utilizing this device must manipulate it in one hand while attempting to manipulate a hypodermic syringe with the other hand. In addition to being awkward and cumbersome and raising serious problems of coordination, the technique entailed in the use of this device seriously limits the freedom of operation of its user.
Other vein stabilizer structures have been devised. One such device is characterized by a framework supporting a movable vein-depressing member as well as a movable hypodermic syringe. This device, in addition to requiring the concurrent manipulation of two separate components, is characterized by such structural complexity and awkwardness as to seriously impede its practical utility. Another device known in the art is characterized by a separate vein stabilizer or holder which may be strapped to a persons arm. Here again, however, this device also requires manipulation by an attendant apart from and in addition to the manipulation of a hypodermic syringe.
Problems commonly involved in attempting to stabilize a vein to facilitate the insertion of a hypodermic needle entail the maintaining of control over the degree -to which flesh is depressed in the vicinity of a vein so as to avoid bruising and the continuous and accurate defining of a target area into which a syringe needle is to be advanced. Additional points of concern have related to the ease with which a vein stabilizer may be manipulated along a vein so as to select a desirable site for needle penetration and the reliability with which a selected vein area may remain continuously stabilized While a syringe needle is advanced and inserted.
It is a principal object of the present invention to provide an improved vein stabilizer structure which enhances the ease with which a hypodermic syringe needle may be inserted and which substantially obviates the difliculties of previously known vein stabilizer structures.
It is a palticular object of the invention to provide a structurally simple, inexpensive, and light weight vein stabilizer which may be conveniently and readily attached directly to a conventional hypodermic syringe.
It is a further object of the invention to provide such an improved vein stabilizer which may be utilized solely by manipulating a syringe with one hand.
An additional object of the invention is to provide such an improved vein stabilizer by means of which relatively accurate control over the degree of flesh depression may be automatically maintained.
It is also an object of the invention to provide such an improved structure which continuously indicates and defines the area into which a hypodermic syringe needle point is to be inserted, which area generally faces the needle point and the syringe manipulator.
It is likewise an object of the invention to provide such an improved apparatus which may be readily repositioned or slid along a vein while maintaining a continuous vein stabilizing action.
The preferred apparatus presented through this invention for accomplishing the foregoing objectives is characterized by a unique combination of frame means, connecting means adapted to secure the frame means to a hypodermic syringe, and stabilizing means.
The stabilizing means ofthis apparatus includes spaced leg portions which are adapted to extend generally longitudinally of a hypodermic syringe When the frame means is connected thereto. This leg means, at least in part, is slidably received by the frame means. The leg portions, at least prior to the insertion of a needle carried by the syringe, are adapted to extend beyond the point of the needle. A connecting portion extends between the leg portions of the stabilizing means. This connecting portion, at least prior to the insertion of the needle, is adapted to be disposed generally outward of the point of the needle.
In the preferred and most advantageous form of the invention, the stabilizing means is characterized by a unitary, resilient and generally U-shaped member. In this preferred embodiment, each leg portion of the stabilizing means, when the frame means is connected to a syringe, is deflected generally away from the axis of the needle of the syringe and then is deflected generally back toward the axis of the needle to define substantially straight, flesh-depressing portionspThe connecting portion of the stabilizing means, in the preferred embodiment, extends from these flesh-engaging portions generally toward the axis of the syringe needle and is of generally concave configuration in the direction facing these flesh-engaging portions.
In describing the invention, reference will be made to the preferred embodiment illustrated in the application drawings.
In the drawings:
FIGURE 1 is a perspective view illustrating a conventional hypodermic syringe to which a preferred form of the stabilizer means of this invention has been attached;
FIGURE 2 is a sectional view of the FIGURE 1 as- 55 sembly as viewed alongthe section line 2 -2;
FIGURE 3 is a fragmentary, elevationalview showing the FIGURE 1 apparatus about to be engaged with a person so as to stabilize a vein;
FIGURE 4 illustrates, in a fragmentary fashion, the FIGURE 1 assembly with the vein stabilizer in flesh engagement so as to stabilize a vein;
FIGURE 5 is a fragmentary view of the FIGURE 1 assembly illustrating the manner in which a hypodermic syringe needle is inserted into a vein while the vein remains stabilized;
FIGURE 6 is an enlarged, fragmentary, plan view of the FIGURE 1 assembly as viewed along the direction 66 of FIGURE 4; and
FIGURE 7 is an enlarged sectional view of a stabilized vein into which a hypodermic syringe needle has been inserted as viewed along section line 7-7 of FIGURE 5.
In FIGURE 1 there is illustrated an assemblycomprising a conventional hypodermic syringe 1 to which is attached a preferred form of the vein stabilizer means 2 of the present invention.
Hypodermic syringe 1, in a conventional manner, includes a barrel or cylinder portion 3, a plunger or piston component 4, and a hollow needle 5.
The principal components of the stabilizer means 2 comprise a frame 6, connecting clips 7 and 8, and generally U-shaped, vein-stabilizing member 9.
In the embodiment of the stabilizer means 2 shown in the application drawings, the frame 6 and connecting clips 7 and 8 may be fabricated as unitary components from a piece of resilient sheet metal. The clips 7 and 8 may each be defined by portions of this sheet material which are bent out of the general plane of the frame 6 to define opposing, resilient, syringe barrel-embracing means. Thus, clip 8, as shown in FIGURE 2, is defined by resilient portions 8a and 8b which cooperate to define a generally C-shaped clip 8.
With clips 7 and 8 both comprising generally C-shaped, resilient attaching means, the assembly 2 may be quickly attached to or detached from the barrel portion 3 of a hypodermic syringe 1. It will be understood, of course, that the resilience of the clips 7 and 8 should be such as to effectively secure the assembly 2 against movement in relation to the syringe barrel 3 while injections or fluid withdrawals are being made.
The generally U-shaped stabilizer member 9 is fabricated of spring-like or resilient material such as stainless steel.
Spring-like, stabilizer member 9 includes leg portions 90 and 9b which are in spaced, parallel relationship and extend generally longitudinally of the syringe 1 when assembled with the frame 6 and syringe 1 as shown in FIG- URE 1. A generally accurate connecting portion 90 extends between the outermost ends of the leg portions 9b and 9a as shown in FIGURE 1.
As shown, stabilizer member 9 comprises a unitary, flattened, wire-like member. The cross section of each leg portion 9a and 9b, as shown in FIGURE 2, is generally rectangular and elongate in a direction transverse of a median plane P common to the stabilizer 9, frame 6, and hypodermic syringe -1.
Leg portions 9a and 9b .are slidably received by the frame 6. As shown in FIGURE 3, this slidable mounting of the leg portions 9a and 9b may be accomplished by bent-over, frame edge portions 6a and 6b which define leg-portion-receiving openings 60 and 6d respectively.
As shown, frame edge portions 6a and 6b may be discontinuous in nature, i.e. interrupted where the components of the clip members 7 and 8 are bent away from the base 6. Where clip members 7 and 8 are fabricated as separate components attached to the base 6, the bentover frame edge portions 6a and 6b would preferably be continuous in nature.
Leg portions 9a and 9b, at bending points 10 and 11, respectively, are deflected away from the needle axis X and at bending points 12 and 13, respectively, are rebent toward the needle axis X so as to define substantially straight, flesh-engaging and vein-stabilizing leg portion sections 9d and 9e. These flesh-engaging, leg portion sections 9d and 9e are thus displaced from the projected continuation of the leg portion sections 91 and 9g which extend respectively between bending points 10 and 11 and the free ends of the leg portions.
As shown in FIGURES l, 3, and 6, the connecting portion 9c is of generally U-shaped or concave configuration in a direction generally facing the flesh-engaging leg portion sections 9d and 9e. Connecting portion 9 is bent relative to leg portion sections 9d and 92 so as to extend from these portions generally toward the needle axis X.
With the components of the assembly disposed as shown in FIGURES l and 3, i.e. positioned for the initiation of an injection or blood-withdrawing operation, the leg portions 911 and 9b, which are generally symmetrically disposed on opposite sides of median plane P, extended beyond the needle point 5a. In this prior-to-injection arrangement, the connecting portion 9c, of course, is disposed generally outward of i.e. beyond, the needle point 5a.
Having described the overall structure of the asembly shown in FIGURE 1, the mode of operation of this device will now be considered. In so doing, the several advantages attributable to the invention will become more readily apparent.
FIGURE 3 illustrates the hypodermic syringe and stabilizer assembly positioned above a vein 14 into which medicinal substances are to be injected or from which blood is to be drawn. It will be understood, of course, that the syringe 1 will 'be supported and manipulated in a conventional, one-handed fashion.
FIGURE 4 illustrates the assembly after the fleshengaging portions 12 have been pressed against fleshy portions 15 and 16 on opposite sides of the vein 14 as shown in FIGURE 6.
The straight and generally elongate character of the parallel, flesh-engaging sections 9d and 9e serves to isolate an elongate vein portion 14a as shown in FIGURE 4.
Flesh-depressing sections 9d and 92 may function as runners or skids to facilitate the sliding of the stabilizer 9 along the vein 14 until a desired injection site is located. When the site is thus located, the syringe assembly may be pressed downwardly so as to cause the outer end of the stabilizer 9 to be simultaneously pressed into the fleshy portions 15 and 16 and cause the relative convergence of the needle axis X and the flesh-engaging, stabilizer portions 9d and 9e. Owing to the resilient character of the stabilizer leg portions 9a and 9b, the deflection of the outer end of the stabilizer toward the needle axis will tend to exert a more or less controlled flesh-depressing force, limited by the resilience of these leg portions.
'With the flesh-engaging sections 9d and 9e depressed into the fleshy portions 15 and 16 as shown in FIGURE 4, the vein portion 14a will be immobilized between these leg portion sections. Additionally, as shown in FIGURE 7, the generally arcuate or concave connecting portion have been depressed sufficiently so as to engage the outer end of the stabilized vein portion 14a and constrict the vein flow at point 14b. This constriction of flow through the vein will tend to enlarge the stabilized vein portion 14a, assuming that the flow of blood through the vein is in a direction shown in FIGURE 3, i.e. from bending points 12 and 13 toward connecting portion 9c.
With the apparatus positioned as shown in FIGURE 4, the connecting portion 9c of the stabilizer defines an area 17 facing generally toward the needle point 5a and the person manipulating the syringe 1. This area 17 comprises a target zone toward which the needle point 5a is to be advanced.
With the flesh-engaging portions 12 and 13 depressed as shown in FIGURE 4, these portions, in cooperation with the upwardly bent and abutment-defining, connecting portion 90, will be sufliciently depressed into the flesh portions 15 and 16 as to resist movement of the stabilizer 9 induced by movement of the syringe 1 toward the target zone 17. With the stabilizer 9 being thus resistive to longitudinal movement, the advancing of the syringe 1 toward the target Zone 17 will cause the leg portion sections 9f and 9g to slide into the frame openings 60 and 6d respectively. As Will be appreciated, the resiliently biased, frictional engagement between the slightly curved and springy, leg p rtion sections 9 and 9g and the inner walls of the frame openings 60 and 6d will result in controlled, telescoping movement of the leg portions 9a and 9b into the leg-receiving openings 6c and 6d of the frame 6.
As will be appreciated, this sliding or telescoping action of the leg portions 9a and 9]) enables the target area 17 to remain effectively and continuously defined by the connecting portion 90 of the stabilizer 9 while the needle point 5a is being advanced into the vein 14.
It should be noted that lateral deflection forces, created by the advancing of the needle 5, would tend to deflect the needle point 5a from the target zone 17. Such deflection tendencies are effectively offset by the lateral rigidity of the leg portions 9a and 9b, resulting from their elongate or rectangular, transverse, cross-sectional configuration.
In describing the overall invention, reference has been made to a particularly efficacious preferred embodiment. However, those skilled in the art and familiar with this featured form of the device may well recognize modified or alternative structures which, in effect, would be equivalent to the device shown. Such modifications or alterations, or substitutions, additions or deletions involving various structural features of the invention as shOWn are deemed to be encompassed by the appended claims.
