Definitions
- This invention relates to the safe disposal of hypodermic needles by a guard device which protects the needle tip from exposure after use. More particularly, it relates to a mechanism for a tip protector which is storable on the needle and which automatically locks over the end of the needle when slid into position at the needle tip by the user. It relates specifically to a needle guard mounted on and positively engaged with an intravenous catheter and which disengages from the catheter automatically when the needle guard locks over the end of the catheter insertion needle.
- intravenous catheters these devices are merely exemplary.
- This invention relates to all forms of needle-supported cannulas, such as those used as catheters.
- the needle guard must lock to the needle shaft, covering the needle tip, before the needle guard can be released from its positive engagement with the catheter hub.
- the needle tip cannot be exposed under any circumstances, following attachment of the needle guard and needle to the catheter hub.
- a needle guard is provided that may be installed at the base o the constant diameter insertion needle of an intravenous catheter assembly and which remains positively attached at the base of the catheter until the guard is deployed at the needle tip.
- the needle guard mechanism is of the canted locking plate type described in the cited prior applications, comprising:
- a body having an axial needle passageway extending the length of the body, and also having other laterally-
- a spring mounted in one of the above component cavities, and arranged to hold the sensing end of the lever in contact with the side of the insertion needle shaft.
- This shell will be described herein as comprising an inner shell and a partially surrounding outer shell, with the outer shell being generally the more distal of the two.
- the catheter assembly includes a flexible catheter cannula or sheath, attached to a base containing a tapered internal bore, which is used for the attachment of other devices after the catheter has been inserted into the patient.
- this internal bore has an annular groove formed in its wall near the larger, proximal, or entry end of the bore.
- the outer shell of this invention includes an axial extension from its distal end of generally cylindrical form, which extends into the tapered bore o the catheter hub, reaching past the annular groove formed therein.
- This axial extension referred to hereinafter as the retaining plug, has a central axial internal bore to accommodate the insertion needle, and is divided into a plurality of cylindrical sectors by longitudinal radial slots formed therein, with the slots extending into the larger proximal portion of the outer shell.
- These slots divide the cross-section of the outer shell so as to impart radial flexibility to the cylindrical sectors of the retaining plug, which can flex in cantilever from their attachment to the unslotted proximal portion of the outer shell.
- Each sector of the retaining plug carries on its outer cylindrical surface a barb.
- the longitudinal section of each barb may typically resemble a so-called buttress thread, . or more familiarly, one half of the arrowhead, with the arrow pointing distally along the needle axis.
- the dimensions of the retaining plug and the barbs are such as to allow free axial passage of the barbs within the proximal portion of the internal bore of the catheter hub, when the retaining plug alone is inserted therein.
- Each barb on the retaining plug is located so as to fit into the annular groove in the catheter hub when the retaining plug is expanded radially by the axial insertion of a suitable cylindrical expansion member into the central cylindrical bore of the retaining plug. With the retaining plug thus expanded, it is retained axially within the catheter hub by the engagement of the barbs with the annular groove in the hub.
- the above expansion member referred to hereinafter as a spigot, consists of a substantially cylindrical axial extension of the distal end of the body of the needle guard mechanism.
- the needle guard Prior to use of the catheter assembly, the needle guard is held in the unlocked state by the presence of the needle shaft within the needle guard body, with the needle holding the sensing plate of the lever against the urging of the spring in a position radially removed from the needle axis. This is described more fully in the cited prior applications.
- a radial extension of the sensing plate engages the distal end face of the inner shell, holding the lever and the body axially at the distal end of the cylindrical internal cavity of the shell.
- Figure 1 is a longitudinal sectional view of a needle guard employing a canted-plate locking lever, a described in the cited prior applications, and installed on an intravenous catheter assembly. The assembly is shown in its pre-use or unlocked state.
- Figure 2 is a detail view of the outer shell of the needle guard, shown in longitudinal section.
- Figure 3 is an exterior top view of Figure 2.
- Figure 4 is an exterior distal end view of Figure 2.
- Figure 5 is an exterior proximal end view of Figure 2.
- Figure 6 is a longitudinal sectional view of the needle guard of Figure 1, shown in its after-use or locked state, with the needle guard locked over the needle tip and almost completely withdrawn from the catheter hub.
- Figure 7 is a partial longitudinal sectional view of the junction between the needle guard and the catheter hub immediately following locking of the guard but before removal of the guard from the catheter hub. 5.
- Figure 1 is shown a typical intravenous catheter assembly, comprising flexible cannula 601 mounted in catheter hub 602, and insertion needle 603 mounted in needle base 604. The needle is shown fully inserted in the assembly in its pre-use state, with the needle tip 605 extending slightly beyond the cannula tip 606 in the usual way.
- the needle guard assembly comprises body 607, lever 608, spring 609, inner shell 610, and outer shell 611. The latter two shell portions are typically held together by snap connection 631.
- lever 608 is restrained from moving to the right relative to the shell by the upper end of plate 615 coming in contact with the face 617 of inner shell 610.
- retaining plug 621 extends from the closed left end of the outer shell, and is divided into three or more sections by slots 622, which extend into the larger portion of the outer shell to point 623.
- the shell is molded of a suitable compliant plastic material.
- spigot 619 holds retaining plug 621 in an expanded state, so that barbs 627 engage annular groove 628 in the wall of catheter hub 602. This holds retaining plug 621 axially in the tapered bore 629 of catheter hub 602.
- Spigot 619 may be formed with a slight taper, with the diameter diminishing in the distal direction. This will allow the inwardly-collapsing effort of the several compliant sections of retaining plug 621 to assist the effort of withdrawing the spigot from retaining plug 621.
- the paper may be made sufficiently steep that the spigot can be ejected entirely by this inwardly-collapsing action, without requiring any further withdrawal effort by the user. 5.14
- retaining plug 621 must be held centered in the internal bore 629 of the catheter hub 602, so that barbs 627 do not catch on the edge of groove 628 during withdrawal.
- this alignment is obtained by the engagement of a short cylindrical overhang 632 on the distal end of outer shell 611 with a mating cylindrical shoulder 633 on the proximal end of catheter hub 602, when spigot 619 has withdrawn from the internal bore 620 of retention plug 621, and the outer shell has collapsed inwardly. This radial alignment is maintained until the barbs 627 have been axially withdrawn out of alignment with groove 628, and therefore can no longer accidentally engage the groove, as shown in Figure 6.
