Corner needle removal aid for implanted central venous catheter

Abstract

The insertion device for removing the apical needle of the implantable central venous catheter provided in this invention includes an isolation element for maintaining a safe spatial distance between the non-dominant hand and the apical needle, and a pressing part for positioning the infusion plug. The pressing part defines a channel for accommodating the needle hub of the apical needle, and at least two spaced-apart pressing points located on both sides of the channel, with these pressing points corresponding to the same side of the isolation element. This allows the operator to create a safe distance through the isolation element, while the channel is embedded on both sides of the needle hub. The non-dominant hand applies force through the isolation element and presses against the patient's skin surface through the pressing points, indirectly pressing and positioning the infusion plug located under the skin, thereby allowing the operator to smoothly remove the apical needle with their dominant hand.

Claims

1. An accessory for removing the apex of an implantable central venous catheter, comprising: an isolation article; a pressing portion defining a channel, wherein at least two spaced-apart pressing points are located on both sides of the channel and the pressing points correspond to the same side of the isolation article.

2. The horn removal aid for the implantable central venous catheter as described in claim 1, wherein, The isolation item contains a plate-shaped body.

3. The horn removal aid for the implantable central venous catheter as described in claim 2, wherein, The pressing part has a notch that extends from one end edge of the body to the inside of the body to a predetermined depth, and the space of the notch defines the channel.

4. The horn removal aid for the implantable central venous catheter as described in claim 3, wherein, These pressure points are located on one of the side plates of the body.

5. The pin removal aid for the implantable central venous catheter as described in claim 2, wherein, The body is translucent.

6. The pin removal aid for the implantable central venous catheter as described in claim 5, wherein, The isolation item further includes a first length dimension marking section located on the main body.

7. The horn removal aid for the implantable central venous catheter as described in claim 6, wherein, The isolation item further includes an extension ruler of a predetermined length, which is pivotally mounted on the main body at one end of its long axis, and a second length dimension marking is provided on the extension ruler.

8. The pin removal aid for the implantable central venous catheter as described in claim 1, wherein, The isolation item has a U-shaped portion and an extension portion that extends outward from the closed side of the U-shaped portion for a predetermined length.

9. The horn removal aid for the implantable central venous catheter as described in claim 8, wherein, The passage is defined by the U-shaped space of the U-shaped section.

10. The pin removal aid for the implantable central venous catheter as described in claim 8, wherein, These pressure points are located on one side of the U-shaped section.
