Description

Technical area

[0001] The invention relates to a treatment set provided with a peripheral venous catheter, in particular for wound care. State of the art

[0002] A catheter is a well-known medical device consisting of a thin tube designed to be inserted into the lumen of a body cavity or blood vessel. It is used, for example, for drainage or infusion of fluids.

[0003] So-called peripheral venous catheters are frequently used in various treatments. They are usually inserted percutaneously into a superficial vein, e.g., in a limb. Due to this preferred use, a peripheral venous catheter is typically supplied and packaged with a needle that runs through the tube. The practitioner places the catheter by inserting the needle, which is coupled to the catheter, and then withdrawing the needle.

[0004] In this document, the term "peripheral venous catheter" should be understood to refer not only to the tube to be inserted into the superficial vein, but also to possible catheter-specific elements attached to it, such as a reflux chamber from which the tube extends and, more optionally, fixation wings extending on both sides of the reflux chamber.

[0005] A peripheral venous catheter can also be used in conjunction with a syringe and saline solution to clean a wound, e.g., prior to wound drainage. In this case, the practitioner uses a treatment set, e.g., a drainage set, which consists of a sterile, sealed package containing various treatment tools such as a syringe, scissors, forceps, and / or a probe.

[0006] However, these treatments require a multitude of manipulations, as the practitioner must handle the catheter, which is connected to a needle, and the aforementioned treatment set. In this context, each of these manipulations increases the risk of both medical error and unwanted patient contamination. Description of the invention

[0007] One object of the invention is to provide means that can facilitate wound care and limit the associated medical risks.

[0008] To this end, the present invention proposes a treatment set with a needle-free peripheral venous catheter. This treatment set facilitates wound care and reduces the associated medical risks, as it eliminates the need to handle both the catheter and the needle, particularly to decouple them. The practitioner can directly grasp the catheter without further manipulation and use it with a syringe and saline solution. The absence of a needle also reduces waste of the raw material from which the needle is made and significantly limits the costs of the practitioner's medical intervention.

[0009] The treatment kit according to the invention preferably consists of a sterile, closed package enclosing one or more treatment tools, including the aforementioned catheter and, more preferably, a syringe. In this way, the treatment tools essential for wound care are provided in a single package, further reducing handling for the practitioner.

[0010] In one embodiment, the catheter is plugged onto and / or attached to a delivery end of the syringe. This further simplifies handling for the practitioner. Plugging it onto the syringe is easy to implement in a production line without requiring additional raw materials.

[0011] The attachment or fastening preferably occurs at the return flow chamber of the catheter, so that the delivery end penetrates into the return flow chamber. Since the return flow chamber is usually conical, the delivery end terminates there by attaching it, creating a substantially tight connection between the functional interior of the syringe and the interior of the catheter tube.

[0012] Attachment, e.g., with a suitable fastening and / or sealing material such as an adhesive, has the advantage of providing a more secure and reliable connection between the syringe and the catheter. It is also suitable in cases where interlocking is not possible due to the geometry of the return chamber and the syringe's discharge end.

[0013] Preferably, the catheter and syringe are molded in one piece. In particular, they are made of a single material, typically a plastic. This allows the resulting treatment tool to be used directly for wound care without prior handling. The advantage is that, due to its one-piece design, it is stable and has no gaps between the catheter and syringe, thus ensuring a completely leak-proof seal. This treatment tool can be easily manufactured by plastic molding or other known and suitable techniques.

[0014] In one embodiment of the invention, the treatment tools comprise at least scissors, tweezers, compresses, a sterile drape, a wick, and a probe. All treatment tools useful for wound care are made available to the practitioner in a single treatment kit with minimal manual intervention.

[0015] In one embodiment, the sterile, closed package enclosing the treatment tools is subdivided and comprises a first compartment that is oversized with respect to the dimensions of the catheter, preferably with respect to all dimensions of the catheter, with the catheter being arranged in this compartment. This makes it easy for the practitioner to grasp the catheter regardless of the orientation of their hand relative to the package and / or the compartment, which has the advantage of reducing possible grasping attempts and manipulation by the practitioner, as well as the time required for this. Preferably, at least one of the treatment tools is arranged together with the catheter in the first compartment.

[0016] This includes, for example, the syringe, especially in cases where the syringe and the catheter are attached to each other and / or inserted into each other, but also in any other case, so that these two tools important for wound care are available in a single compartment of a single package.

[0017] The treatment set proposed here can alternatively be described within the scope of the invention as a sterile, closed package enclosing one or more treatment tools, including a peripheral venous catheter, with the other possible treatment tools being selected from a syringe, scissors, forceps, compresses, a sterile cloth, a wick, and a probe. The relevant embodiments and the advantages described above apply mutatis mutandis.

[0018] Please note that in this document, the use of "encompass," its variants, and conjugations does not exclude the presence of elements other than those mentioned. The use of the indefinite article "ein," "eine," or the definite article "der," "die," or "das" to introduce an element in this document does not exclude the presence of multiple such elements.

[0019] The following describes a method for preparing a treatment kit according to the invention prior to wound care. The treatment kit of the method consists of a sterile, sealed package enclosing one or more treatment tools, including: - a peripheral venous catheter with a tube extending from a return chamber, and - a syringe with a dispensing end.

[0020] The method includes the following steps: (i) open the packaging; (ii) take the catheter and 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 the treatment fluid into the syringe from a free end of the catheter tube.

[0021] This method fully meets the objective of the invention, as it facilitates wound care while simultaneously limiting the associated medical risks. The manipulations enabled by this treatment set are minimized and simplified, as described above. This effect is further enhanced when the syringe and catheter are attached and / or molded in one piece, with step (ii) occurring in a single grasping action.

[0022] The sequence of steps (iii) and (iv) and the optionality of step (iii) are quite advantageous in this regard. Because the withdrawal of the treatment fluid is enabled directly via the aforementioned free end of the tubing of the treatment tool, which is formed by attaching the catheter to the syringe, it is not necessary to provide for this withdrawal via the dispensing end of the syringe, as is known from the prior art, before this attachment takes place. This reduces handling for the practitioner and makes it important to provide the catheter already attached to the syringe in the sterile, sealed package.

[0023] For the purposes of this method, the term "treatment fluid" is understood to mean any fluid useful for wound care. This can be a treatment fluid or a fluid for cleansing the wound. The treatment fluid consists of physiological saline, i.e., a mixture of H2O and NaCl, which defines an isotonic solution with 0.9% NaCl, according to a preferred embodiment. The embodiments and advantages of the treatment set can be applied mutatis mutandis to the present method. Short description of the drawings
