Abstract

An insertion device for inserting a catheter into a patient is disclosed. The insertion device combines needle insertion, guidewire advancement, catheter insertion, and needle shielding into a single device. In one embodiment, an insertion device includes a housing and a hollow needle extending distally from the housing. At least a portion of the catheter is pre-disposed on the needle such that the catheter is disposed generally outside of the housing. The insertion device also includes a guidewire, and a advancement assembly configured to selectively push a distal end of the guidewire out of the distal opening of the needle in preparation for distally advancing the catheter. The advancement assembly is further configured to distally advance the catheter prior to covering the needle after use. The insertion device is configured to be grasped and used by a single hand of a user during advancement of the guidewire and catheter.

Claims (11)

1. A needle assembly comprising: a needle defining a needle lumen; A recess defined in a sidewall of the needle to enable blood to pass through the needle lumen when the open distal tip of the needle is disposed in a blood vessel of a patient that carries blood, and A flash indicator configured to indicate the presence of blood within the needle lumen when the open distal tip of the needle is disposed in a blood vessel of a patient, the flash indicator comprising an absorbent material disposed about the needle such that the absorbent material is disposed over and covers the notch, the absorbent material being configured to absorb blood passing from the needle lumen through the notch such that the absorbed blood is viewable by a user of the needle assembly.
2. The needle assembly of claim 1, wherein the absorbent material is configured such that blood continuously moves along the absorbent material while the open distal tip of the needle is disposed in the blood-conveying vessel of the patient.
3. The needle assembly of claim 1, wherein the absorbent material is generally cylindrical and comprises at least one of a natural material and a synthetic material.
4. The needle assembly of claim 1, wherein the absorbent material extends proximally from the notch along an outer surface of the needle.
5. The needle assembly of claim 1, wherein the absorbent material comprises cotton and the absorbent material is covered by a cover.
6. The needle assembly of claim 5, wherein the cover comprises a polymeric material.
7. The needle assembly of claim 1, wherein the absorbent material is configured to expand in at least one of a radial direction and a longitudinal direction upon absorbing a fluid.
8. The needle assembly of claim 1, wherein a marker is disposed adjacent to the absorbent material and is configured to meter an amount of blood absorbed by the absorbent material.
9. A needle assembly, comprising: A needle defining a needle lumen, the needle being at least partially disposed in the housing; A recess defined in a sidewall of the needle to enable blood to pass through the needle lumen when the open distal tip of the needle is disposed in a blood vessel of a patient that carries blood, and A flashing indicator configured to indicate the presence of fluid in the needle lumen when the open distal tip of the needle is disposed in a blood vessel of a patient that conveys blood, the flashing indicator comprising an absorbent material disposed about the needle and configured to absorb fluid passing from the needle lumen through the notch such that the absorbed fluid is observable by a user of the needle assembly, the absorbent material comprising: A first portion disposed proximate to the recess such that the first portion of the absorbent material is disposed over and covers the recess; A second portion attached to the inner surface of the housing, and A tether portion interconnecting the first portion and the second portion of the absorbent material.
10. The needle assembly of claim 9, wherein the needle is retractable into the housing, the tether portion being configured to break when the needle is retracted such that the second portion of the absorbent material remains on the inner surface of the housing.
11. The needle assembly of claim 9, wherein a portion of the housing proximate the second portion of the absorbent material is translucent to enable the user to see the fluid absorbed by the second portion of the absorbent material.

Description

Catheter placement device including an extendable needle safety member Case division information The present application is a divisional application of patent application number 202110775673.4, 13 filed 2016 and entitled "catheter placement device including an extendable needle safety member", and a divisional application of patent application number 201680037398.3, entitled "catheter placement device including an extendable needle safety member", filed 2016 and 13. Cross-reference to related patent applications This patent application claims the benefit of U.S. provisional patent application 62/162,548 entitled "CATHETER PLACEMENT DEVICE Including an End-Mounted Advancement Component," filed 5/15/2015, the entire contents of which are incorporated herein by reference. Disclosure of Invention Briefly, embodiments of the present invention relate to an insertion device for inserting a catheter or other tubular medical device into a patient. The insertion device combines needle insertion, guidewire advancement, catheter insertion, and needle shielding into a single device. In one embodiment, an insertion device includes a housing and a hollow needle extending distally from the housing.
