Problems solved by technology

[0013] This step requires a quick action by the operator, which is usually incomplete or imperfect due to the frequent pressing of the tubular body, causing some blood to flow out and creating a risk of infection transmission due to operator contact, contamination of the surrounding environment, and the patient's possible panic and anxiety at the sight of his own blood
[0014] In addition, the large pressure required on the blood vessel, or mistakenly on the tubular body of the catheter, may cause pain to the patient by squeezing the area of ​​the body that has been pierced to introduce the catheter into the blood vessel, and may suffer from inherent pain. effects of disease

Embodiment Construction

[0042] With reference to the accompanying drawings, reference numeral 1 generally designates an anti-reflux catheter of the invention, hereinafter referred to simply as catheter 1 , comprising a central body 2 having a generally tubular frusto-conical shape and defining a chamber 3 therein, which The chamber is used to pass fluid medication to be infused into the blood vessels of the patient.

[0043] Two wings 4 extend bilaterally from the central body 2 and provide two surfaces for the catheter 1 to be placed and attached to the patient's epidermis near the point of injection.

[0044] A tubular flexible cannula 5 extends from the distal end 2A of the body 2 and combines with the body 2 to form the catheter 1 .

[0045] The end 2B of the body 2 facing away from the cannula 5 is formed with an opening whose outer profile has a standard connection profile designed to couple to a matching profile of a cooperating drug delivery tube (not shown).

[0046] A sleeve 7 made of elas...

Abstract

The anti-reflux catheter comprises: a central support body (2) having an inner longitudinal passage chamber (3); a cannula (5) extending out of one end (2A) of the central body (2) and connected to the inner chamber (3); a transverse opening (8) which extends through the central body (2) and communicates with the inner chamber (3); an outwardly extending mouthpiece (9) of the transverse opening (8); a flexible sleeve (7) longitudinally accommodated in the inner chamber (3) at the transverse opening (8) and having an outer surface facing such transverse opening (8); said mouthpiece (9) having pressure means (10, 1 1 ) associated therewith, which act upon said sleeve (7) and are movable between an idle position or an operating pressed position, and vice versa.

Description

technical field [0001] The present invention relates to an anti-reflux catheter which is integrally designed to be introduced into a blood vessel of a patient using a coaxially received puncture needle and capable of preventing outward blood reflux when the puncture needle is removed from the catheter. Background technique [0002] Flexible catheters are known that are designed to be introduced into a patient's blood vessel using a needle that is simultaneously inserted prior to injection to impart this relatively temporary axial rigidity, thereby allowing it to penetrate the blood vessel without bending. Introduced axially into the lumen of the catheter. [0003] Typically, a catheter suitable for introduction into a blood vessel comprises a flexible tubular body with a support element at one end designed proximally (ie facing the operator during use), known as and hereinafter referred to as "the bushing", the support element has an internal axial access cavity seamlessly ...
