Definitions

  • This invention relates generally to intravenous (I-V) catheter placement devices that reduce the likelihood of accidental needlestick injuries.
  • I-V catheter introducer needles One of the particular problems has been associated with the use and disposal of I-V catheter introducer needles by health care workers.
  • I-V catheter introducer needles There have been various devices developed for the destruction of the introducer needles or cannula used with I-V catheters. Additional devices have been developed for the capping or hooding of I-V catheter introducer needles, all of which attempt to minimize the likelihood of needlestick injuries to health care workers and others after the needles have been used.
  • an I-V catheter injection device having a hollow body or barrel, with a nose attached to one end of the body and closed at the opposite end.
  • the nose is disposed to the interior of said hollow body through a passageway, integral to the nose.
  • One end of a hollow needle which is embedded in a hollow and transparent needle hub, is controlled in the passageway within the nose by a shaft appendage of the needle hub, and is in contact with energy storage means such as a spring, placed into the passageway ahead of the needle hub shaft.
  • energy storage means such as a spring
  • the other end of the needle passes through the spring and the passageway, and protrudes through boot (which may be elastic or rigid) that is attached to the nose of the catheter injection system.
  • boot which may be elastic or rigid
  • the needle hub has two symmetrical winged beams, which are cantilevered from the back of the needle hub in the direction of the needle hub shaft and project at an angle away from the needle hub shaft and needle hub.
  • the geometry of the distal end of each winged beam is defined with angled catches for fixing the needle hub, with the spring in contact with it, into retainer slots in the sidewall of the nose.
  • On the adjacent side of each catch is a release contact point for operationally releasing the needle hub from retainer slots during retraction of the needle and needle hub into the body of the device during use of the device.
  • the needle hub In an assembled state, the needle hub is held by one of the catches on the winged beams in position in the nose against the spring and ready for use.
  • the opposite catch floats in its nose slot, which is slightly longer than the first nose slot, until actuation of the retraction cycle.
  • I-V catheter placement device Use of the I-V catheter placement device is accomplished by holding the device at the finger grips in one hand with the orientation message "USE THIS SIDE UP," inscribed on the body of the device, visible to the clinician and with the needle pointing away from the clinician.
  • the injection site of the patient is held with the other hand, such that the second hand is behind the needle at all times and is thus shielded from possible accidental needlestick.
  • the introducer needle, with the catheter is then injected part way into the patient's vein at the desired location, such that just the tip of the needle and catheter have been inserted.
  • the clinician receives visual verification of proper veinal placement of the needle and catheter by observing the appearance of blood "flash-back" in the inner cavity of the needle hub (which is magnified) .
  • the two release tabs on the sides of the body are again simultaneously depressed and released. This action releases the remaining needle hub catch from its slot in the nose, and the needle hub with the needle attached thereto, is projected by stored energy in the spring (or other energy storage means) into and retained within the body of the device. Visible verification of such needle retraction is provided to the clinician by him or her observing that the needle hub is positioned at a second fixed reference line at the back of the body of the device labeled as "2.” In addition, audible indication of such retraction is provided by a "clicking" sound which is audible when the release tabs are depressed. As the needle tip passes the boot at the nose of the device, the hole in the boot through which the needle has passed closes, and blood flow from the catheter into the body of the device is restricted .
  • External blood flow from the device is further restricted by the sealing action between the boot and the internal wall of the catheter head.
  • the clinician applies digital pressure at the entry point of the catheter into the patient's body to block blood flow from the catheter, removes the body of the device (which acts as a plug in the catheter head) , and inserts the I-V line into the catheter head. Digital pressure is then removed, completing the process.
  • An alternative embodiment of this invention provides for sequential depression of the individual release tabs to actuate needle retraction.
  • An alternative embodiment of this invention provides a second method of automatically plugging the nose of the device for flow restriction and added needle security.

  • This invention provides an I-V catheter placement device operable with one hand and having a two-stage needle retraction mechanism using one set of release tabs.
  • the first stage of retraction effectively blunts the needle tip and allows insertion of the full length of the catheter without risk to the patient, while the second stage of retraction fully retracts the needle hub, with its contaminated introducer needle attached, harmlessly into the body of the catheter placement device where it is captured and encapsulated, thus protecting the clinician from an accidental needlestick injury.
  • Once encapsulated inside the body of the catheter placement device there is no risk of accidentally pricking or poking human tissue, thus minimizing the likelihood of transfer of blood borne pathogens which may be carried by fluids contained on the surface of or within such needle.
  • Figures 1 and 2 illustrate the catheter placement device 1 of this invention with the needle 13 and catheter 43 in its normal pre-injection position.
  • Figure 2 shows the final position of the needle 13 after operation of the retraction cycle so that the needle hub 41 (with needle 13 attached) is held in hollow catheter body 17 and rendered harmless after the placement of the catheter 43 has taken place.
  • the I-V catheter placement device 1 has relatively few components .
  • I-V catheter placement device 1 has a hollow barrel or body 17 with a nose 3 attached to one end. Barrel 17 is closed at the opposite end. A passageway 9 through nose 3 communicates with the interior of the hollow barrel 17. A proximal end of hollow needle 13 is fixed in a through hole 14 of needle hub shaft 39, which is in communication with a magnified blood "flash-back" verification cavity 53 in needle hub 41. Membrane 31 is positioned in the verification cavity 53 remote from needle 13 to allow airflow through membrane 31 but to prevent flow of blood into hollow barrel 17 as the catheter is inserted into a patient's vein.
  • Needle hub 41 is controlled in the passageway 9 within the nose 3 by needle hub shaft 39, and is in contact with spring 15, which is compressed into the passageway 9 ahead of needle hub shaft 39.
  • the distal end of the needle 13 passes through spring 15, passageway 9, and nose boot 25 and protrudes from the nose end of the catheter injection system 1.
  • Catheter 43 is fixed to nose 3 at catheter head 45 by light friction between catheter head 45 and nose boot 25 which provides a liquid tight seal between the catheter head 45 and nose boot 25 and also makes them easily separable during use .
  • Needle hub shaft 39 into which is fixed the proximal end of needle 13 in a through hole 14 running the length of shaft 39, is an appendage of needle hub 41.
  • Needle hub 41 has winged beams 33R and 33L which are cantilevered from the back of the needle hub 41 in the direction of the needle hub shaft 39 and project at an angle away from needle hub shaft 39.
  • the geometry of the distal end of winged beams 33R and 33L is defined with an angled catch 35R for coupling the needle hub 41, with spring 15 in contact therewith, into retainer slot 7R in the side wall of nose 3.
  • catch 35R On the adjacent side of catch 35R is a release contact point 37R for operationally releasing needle hub 41 from retainer slot 7R through the application of force during retraction of the needle 13 into the body 17 during use.

  • needle hub 41 is held by angled catch 35R on winged beam 33R in its position in passageway 9.

  • the tip or point 59 of needle 13, with the catheter 43 is just placed into the patient at the desired location. Verification of correct location of the catheter 43 is obtained by clinician observation of blood flash-back into magnified transparent verification cavity 53 in needle hub 41.
  • release tabs 29R and 29L are simultaneously depressed two times a) effectively to blunt the needle tip, and b) to retract needle 13 into the body of catheter 17.
  • actuation of the catheter placement device 1 retraction cycle occurs when release tabs 29R and 29L, just in front of finger grips 27 of the catheter placement device 1, are simultaneously depressed.
  • force is applied by contact pads 19R and 19L on the interior surfaces of release tabs 29R and 29L to release contact points 37R and 37L on the winged beams 33R and 33L of the needle hub 41.

Abstract

L'invention concerne un dispositif (1) de positionnement de cathéter intraveineux. Ce dispositif comprend un corps creux (17) avec une pointe (3) sur une extrémité. Un embout d'aiguille (41) vient s'insérer dans la pointe (3) et renferme une aiguille (13) encastrée dans ce dernier. Un cathéter (43) peut coulisser librement le long de l'aiguille (13) et recouvre sensiblement la tige (39) de l'aiguille (13). Des éléments à ailettes (33R, 33L) sur l'embout (41) comprennent des cliquets (35R, 35L) et des pattes de dégagement (29R, 29L) qui coopèrent avec des encoches (7R, 7L) ménagées dans la pointe (3) pour retenir l'embout (41) dans cette dernière. Une cavité transparente grossissante (53) dans l'embout (41) permet de voir le sang dans la cavité (53) pour vérifier que le cathéter intraveineux (43) est bien inséré correctement. Un dispositif de stockage d'énergie (15) en contact avec l'embout (41) dans le corps creux retient ce dernier, de manière libérable, afin d'éviter qu'il ne se projette trop tôt dans le corps creux (17). Lors de l'insertion du cathéter (43), l'aiguille (13) dans le patient, appuie sur les pattes de dégagement (29R, 29L), et déclenche l'embout (41). Ainsi, l'aiguille (13) est enfoncée dans le cathéter (43), ce qui projette l'embout (43) et l'aiguille (13) dans le corps creux (17).
