Description

PICC fixing device

Technical Field

The utility model relates to a medical treatment auxiliary instrument especially relates to a PICC fixing device.

Background

The PICC (namely the peripheral central catheter) is a catheter which is inserted through a peripheral vein and is placed into the central vein at an inner opening end, can effectively protect the upper limb vein, improves the life safety of a patient, and is used for the intravenous infusion treatment (especially the long-term injection treatment of irritant medicines) of patients in medium-long term and long term.

The traditional catheter fixing application is to fix by using a tension-free transparent dressing, has poor fixing effect and is particularly easy to remove. The currently clinically common catheter fixing device fixes the connecting part of the catheter and the extension tube thereof by using the Simian button, the Simian button is formed by arranging two containing cavities on the upper surface of the adhesive tape to fix the connecting part, the operation is complex, and the working efficiency is low; because the connecting part is obviously higher than the surface of the skin, the connecting part is fixed by strong pressure, so that the puncture part is easily red and swollen or extravasated blood is easily caused; the Sile buckle can only fix the vertical section of the far skin end of the catheter but can not directly fix the near skin end of the catheter, so that once the catheter is pulled, the near skin end of the catheter can move to cause partial separation, the external part of the catheter is longer and longer, and simultaneously, the PICC treatment cycle of a plurality of patients is as long as more than one year, so that the catheter needs to be punctured for many times during treatment, the pain is increased, the health psychology of the patients is influenced, and the nursing workload of medical workers is increased; in addition, the length of the exposed part of the catheter is different due to individual differences of patients, and if the length of the catheter outside the body is too long, the catheter is not beneficial to regulation and fixation. Therefore, how to design a catheter fixing device with good fixing effect, difficult tube detachment and suitability for different exposed lengths is an important problem to be solved urgently by those skilled in the art.

The sections of the leading-out part and the guide pipe fixing groove are both arc-shaped structures matched with the guide pipe.

The outer edge of the leading-out part and the catheter fixing groove are respectively provided with a plurality of upper pressing sheets for fixing the PICC.

The bottom surface of the upper pressing sheet is provided with an arc-shaped groove matched with the guide pipe.

The thickness of the fixed part is 1.0 mm-2.5 mm, and the depth of the conduit fixed groove and the depth of the leading-out part are 0.5 mm-2.0 mm.

The utility model has the advantages of simple structure, ingenious, simplified operating procedure, fixed effectual, effectively avoid taking off the pipe, be applicable to the fixed different pipe that exposes length. Specifically, the skin-proximal end of the catheter can smoothly pass through the fixing part through the tube inlet opening during fixing, and the fixing part can be quickly adhered to the arm of a patient; the guide pipe is spirally fixed in the guide pipe fixing groove, so that the exposed section of the guide pipe is regular and fixed, the fixing effect is good, the guide pipe can be effectively prevented from being pulled, the probability of pipe falling is further reduced, and the safety is high; the guide tube fixing groove is communicated with a plurality of leading-out parts, is suitable for fixing guide tubes with different exposed lengths, and has wide application range.

Detailed Description

As shown in fig. 1-3, the PICC fixing device of the present invention includes a fixing portion 2 (the fixing portion 2 is made of flexible material) for fixing a catheter 1 and having a ring structure, wherein the bottom surface of the fixing portion 2 is provided with an adhesive layer 3 for adhering the fixing portion to the arm (the adhesive layer 3 is adhered with a smooth film when leaving the factory);

the fixing part 2 is provided with a tube inlet opening 4 in a linear structure, and the skin-proximal end of the catheter 1 passes through the tube inlet opening 4 during fixing, so that the puncture point is positioned in the middle of the fixing part 2; the upper surface of the fixing part 2 is provided with a spiral-structured catheter fixing groove 5 for fixing the catheter 1 and a plurality of leading-out parts 6 communicated with the catheter fixing groove 5, the leading-out parts 6 extend outwards from the catheter fixing groove 5 to the outer edge of the fixing part 2, and the leading-out parts 6 can lead the far-skin end of the catheter 1 out of the fixing part 2; the sections of the conduit fixing groove 5 and the leading-out part 6 are both arc structures matched with the conduit 1, the radius of the conduit fixing groove 5 and the radius of the leading-out part 6 are consistent with the radius of the conduit 1, and the depth of the conduit fixing groove 5 and the depth of the leading-out part 6 are greater than the radius of the conduit 1;
