Description

Title of the invention: Care set technical field

[0001] The invention relates to a care set equipped with a peripheral venous catheter, particularly for wound care, and a method of preparing such a care set prior to wound care. Previous art

[0002] A catheter is a known medical device comprising a thin tube intended to be inserted into a lumen of a body cavity or blood vessel. It is used, for example, for drainage or infusion of fluid.

[0003] So-called "peripheral venous catheters" are frequently used in various medical procedures. They are generally inserted percutaneously into a superficial vein, for example, in a limb. Because of this primary use, a peripheral venous catheter is typically supplied and packaged with a needle that passes through the tube. The practitioner inserts the catheter by inserting the needle coupled to the catheter and subsequently withdrawing the needle.

[0004] In this document, the term "peripheral venous catheter" is to be understood as referring not only to the tube intended to be inserted into the superficial vein but also to any catheter-specific elements attached to it, such as, for example, a reflux chamber from which the tube extends and, more optionally, fixation wings extending on either side of the reflux chamber.

[0005] A peripheral venous catheter can also be used with a syringe and saline solution to clean a wound, for example prior to packing. In this case, the practitioner uses a wound care kit, for example a packing kit, consisting of a sterile sealed package containing various wound care tools such as a syringe, scissors, forceps and / or a stylus.

[0006] However, these procedures require a large number of manipulations because the practitioner must handle the catheter coupled with a needle and the aforementioned treatment kit. In this context, each such manipulation increases both the risk of medical error and undesirable contamination for the patient. Description of the invention

[0007] An object of the invention is to provide means facilitating the care of wounds and limiting the related medical risks.

[0008] To this end, the present invention proposes a wound care kit having a peripheral venous catheter and without a needle. The wound care kit facilitates wound care and allows This limits the associated medical risks, as it eliminates the need to handle both the catheter and the needle simultaneously, particularly to disconnect them. The practitioner can then directly grasp the catheter without further manipulation and use it with a syringe and saline solution. The absence of a needle also reduces the waste of the raw material used in its construction and significantly lowers the costs of the procedure.

[0009] The wound care kit according to the invention preferably consists of a sterile, sealed package containing one or more wound care tools, including said catheter, and more preferably, a syringe. Thus, the essential wound care tools are provided in a single package, further reducing handling by the practitioner.

[0010] According to one embodiment, the catheter is fitted and / or fixed onto one end of the syringe's dispensing port. This reduces the number of manipulations required by the practitioner. A fitting is easily implemented in a production line without the need for additional raw materials.

[0011] The connection or attachment is preferably made at the level of the catheter's reflux chamber, such that the delivery tip enters the reflux chamber. As the reflux chamber is generally conical in shape, the delivery tip stops there by fitting into it, thus providing an essentially leak-proof connection between the functional interior of the syringe and the interior of the catheter tube.

[0012] A fastening, for example by means of a suitable fastening and / or sealing material such as an adhesive, has the advantage of securing the syringe to the catheter more firmly and reliably. It is also suitable in cases where a push-fit connection would not be possible due to the geometry of the reflux chamber and the syringe's delivery tip.

[0013] Preferably, the catheter and syringe are cast as a single unit. In particular, they are made of a material, typically a plastic. In this way, the resulting medical device can be used directly for wound care without any prior handling. Advantageously, it is robust due to its one-piece construction and the absence of any gap between the catheter and the syringe, making it completely leak-proof. This medical device can be easily produced by plastic molding or any other known and suitable technique.

[0014] In one embodiment of the invention, the wound care tools comprise at least one of the following: scissors, forceps, compresses, a sterile drape, a gauze pad, and a stylus. All the wound care tools useful for wound treatment are made available in a single set with minimal handling by the practitioner.

[0015] In one embodiment, the sterile, closed packaging containing the medical tools is compartmentalized and includes a first compartment that is oversized compared to The catheter is arranged in a compartment that matches its dimensions, preferably one that accommodates all the catheter's dimensions. This makes it easy for the practitioner to grasp the catheter regardless of their hand's orientation relative to the packaging and / or the compartment, thus reducing the need for any attempts to grasp the catheter and the time required for such manipulations. Preferably, at least one of the care tools is arranged in the first compartment with the catheter.

[0016] This refers, for example, to the syringe, particularly in the case where the syringe and the catheter are fixed and / or fitted together, but also in any other case, so as to have these two essential wound care tools in a single compartment of a single package.

[0017] The care kit proposed herein can alternatively be described within the scope of the invention as consisting of a sterile, sealed package containing one or more care tools, including a peripheral venous catheter, the other possible care tool(s) being selected from among a syringe, scissors, forceps, gauze pads, a sterile drape, a wick, and a stylet. The relevant embodiments and advantages described above mutatis mutandis.

[0018] It is noted in this document that the use of "comprendre" (understand), its variants and conjugations, does not preclude the presence of elements other than those mentioned. The use, in this document, of the indefinite article "un" (a), "une" (an), or the definite article "le" (the), "la" (the), or "l'" (the), to introduce an element does not preclude the presence of a plurality of these elements.

[0019] The present invention also proposes a method for preparing a wound care kit according to the invention prior to treating a wound. The wound care kit of the method consists of a sterile, sealed package containing one or more wound care tools, including: - a peripheral venous catheter comprising a tube extending from a reflux chamber, and - a syringe including a dispensing tip.

[0020] The method comprises the following steps: i. open the packaging; ii. take the catheter and the syringe; iii. Insert the delivery end into the reflux chamber if this has not already been done or if the catheter is not attached to the delivery end of the syringe; iv. withdraw a quantity of treatment fluid into the syringe from a free end of the catheter tube.

[0021] This method falls squarely within the scope of the invention in that it facilitates wound care while limiting the associated medical risks. The manipulations proposed via this care set are minimized and simplified as described above. This effect is accentuated when the syringe and catheter are fixed and / or cast as a single unit, with step (ii) being performed by grasping the catheter.

[0022] The order of steps (iii) and (iv) and the optional nature of step (iii) are highly advantageous in this respect. Indeed, since the withdrawal of the treatment fluid is made possible directly via the free end of the tube of the treatment tool formed by attaching the catheter to the syringe, it is not necessary to provide for this withdrawal using the dispensing end of the syringe as known in the prior art before attaching it. This reduces the handling required by the practitioner and makes it appropriate to provide the catheter already attached to the syringe in the sterile, sealed package.

[0023] In the context of this method, the term "wound care fluid" is to be interpreted as any fluid useful for wound care. This may be a treatment fluid or a wound cleansing fluid. The wound care fluid consists of physiological saline, i.e., a mixture of H2O and NaCl defining an isotonic solution of 0.9% NaCl, according to a preferred embodiment. The embodiments and advantages of the wound care kit are applicable mutatis mutandis to the present method. Brief description of the figures
