[0035] The following description, in conjunction with the accompanying drawings, details a puncture needle fixation device provided in this application through specific embodiments and application scenarios.

[0036] like Figure 1 and Figure 3 As shown, a puncture needle fixation device according to some embodiments of this application includes: a fixation film 10, a connector 20, and a first infusion tube 30; the connector 20 is inserted through the fixation film 10 and connected to the fixation film 10 along a first direction X, the connector 20 has a first end 21 and a second end 22 disposed opposite to each other along the first direction X, the first end 21 is connected to the first infusion tube 30, the second end 22 is adapted to be detachably connected to the puncture needle, and the connector 20 is provided with a fluid guiding channel 221, through which the first infusion tube 30 can communicate with the puncture needle.

[0037] In the embodiments of this application, a connector 20 is provided in the fixing film 10, so that the first end 21 of the connector 20 is connected to the first infusion tube 30, and the second end 22 is detachably connected to the puncture needle. The connector 20 is provided with a fluid guiding channel 221. When the connector 20 is connected to the puncture needle, the fluid guiding channel 221 communicates with the injection channel in the puncture needle, so that the medicine in the first infusion tube 30 can flow into the puncture needle through the fluid guiding channel 221. At the same time, the connector 20 is connected to the puncture needle, and the fixing film 10 is connected to the connector 20. The fixing film 10 can be attached to the patient's skin surface, which can play a role in fixing the puncture needle. In this way, when the patient's body position changes or the first infusion tube 30 is pulled, it can not only reduce the risk of puncture needle displacement, but also improve the stability of the connection between the puncture needle and the first infusion tube 30, thereby effectively avoiding problems such as poor infusion or infusion leakage.

[0038] In some embodiments, the connector 20 and the first infusion tube 30 are integrally formed.

[0039] In the application embodiment, by setting the connector 20 and the first infusion tube 30 as an integral molded part, not only can leakage of the medicine at the connection gap between the first infusion tube 30 and the connector 20 be avoided, but the operation process of medical staff can also be simplified and clinical efficiency can be improved.

[0040] Optionally, such as Figure 3 As shown, the second end 22 is provided with a first connecting part 222 and a second connecting part 223. The second connecting part 223 is arranged around at least a portion of the outer periphery of the first connecting part 222. The fluid guiding channel 221 passes through the first connecting part 222. The first connecting part 222 is adapted to be inserted into the puncture needle so that the fluid guiding channel 221 communicates with the puncture needle. The second connecting part 223 is adapted to be detachably connected to the puncture needle.

[0041] In this embodiment of the application, by separating the first connecting part 222 for guiding fluid to the puncture needle from the second connecting part 223 for detachably connecting to the puncture needle, leakage of the drug solution at the connection position between the puncture needle and the connector 20 can be avoided, thereby ensuring the smoothness of the infusion process.

[0042] Optionally, such as Figure 3 As shown, the second connecting part 223 is arranged in a ring shape, and the inner circumferential surface of the second connecting part 223 is provided with an internal thread. The second connecting part 223 can be threadedly connected to the puncture needle through the internal thread.

[0043] In this embodiment, by making the second connecting part 223 annularly disposed on the outer periphery of the first connecting part 222, and by providing an internal thread on the inner circumferential surface of the second connecting part 223, the second connecting part 223 can be connected to the external thread provided on the puncture needle through the internal thread. This not only makes the connection between the connector 20 and the puncture needle more stable and firm, but also makes this threaded connection method convenient to operate. Medical staff can quickly complete the connection and fixation between the puncture needle fixation device and the puncture needle, improving clinical operation efficiency.

[0044] Optionally, the second connecting portion 223 includes a plurality of protrusions spaced apart around the outer periphery of the first connecting portion 222, the protrusions being adapted to be inserted into the puncture needle.

[0045] In this embodiment, multiple protrusions are provided at intervals around the outer periphery of the first connecting part 222, and multiple grooves are provided at the corresponding positions of the end of the puncture needle used for connection. One protrusion is inserted into one groove. In this way, the connection between the protrusion and the puncture needle can be fixedly connected to the connector 20 and the puncture needle. This connection method is simple, convenient and easy to operate.

[0046] Optionally, such as Figure 2 As shown, the fixed film 10 has a dressing layer 40 on the side facing the second end 22, and the dressing layer 40 is disposed around at least part of the outer periphery of the connector 20.

[0047] In this embodiment of the application, by providing a dressing layer 40 on the side of the fixed film 10 facing the second end 22 and by making the dressing layer 40 surround the outer periphery of the connector 20, the dressing layer 40 can be used to fix the connection position between the connector 20 and the puncture needle, thereby improving the fixation effect of the puncture needle.

[0048] It should be noted that the dressing layer 40 can be a glucose chlorhexidine dressing layer 40. Glucose chlorhexidine has antibacterial properties. Using glucose chlorhexidine as the dressing layer 40 can reduce the risk of infection at the puncture site and protect the patient's health.

[0049] Optionally, the surface of the fixed film 10 facing the second end 22 is the first surface, the height of the part of the connector 20 exposed on the first surface along the first direction X is H1, and the thickness of the dressing layer 40 along the first direction X is H2, satisfying: H2≥H1.

[0050] In this embodiment of the application, by making the thickness H2 of the dressing layer 40 along the first direction X greater than or equal to the height H1 of the portion of the connector 20 exposed on the first surface along the first direction X, the dressing layer 40 can be better used to fix the connection position between the connector 20 and the puncture needle, thereby further improving the fixation effect of the puncture needle and reducing the risk of displacement of the puncture needle.

[0051] Optionally, such as Figure 2 As shown, the puncture needle fixation device also includes a second infusion tube 50, which is connected to the first end 21, and the second infusion tube 50 can communicate with the puncture needle through the fluid guiding channel 221.

[0052] In this embodiment of the application, by connecting the second infusion tube 50 to the first end 21 and connecting the second infusion tube 50 to the puncture needle through the infusion channel 221, two or more medications can be simultaneously infused through the first infusion tube 30 and the second infusion tube 50 to achieve multi-pathway infusion; it also facilitates infusion operation for medical staff and improves clinical operation efficiency.

[0053] In some embodiments, the connector 20 and the second infusion tube 50 are integrally formed.

[0054] In the application embodiment, by setting the connector 20 and the second infusion tube 50 as an integral molded part, not only can leakage of the drug solution at the connection gap between the second infusion tube 50 and the connector 20 be avoided, but the operation process of medical staff can also be simplified and clinical efficiency can be improved.

[0055] In other embodiments, the connector 20, the first infusion tube 30, and the second infusion tube 50 are integrally formed.

[0056] In the application embodiment, by setting the connector 20, the first infusion tube 30 and the second infusion tube 50 as an integrally molded part, not only can leakage of the medicine be avoided at the connection gap between the first infusion tube 30 and the connector 20 and the connection gap between the second infusion tube 50 and the connector 20, but also the operation process of medical staff can be simplified and clinical efficiency can be improved.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, a sealing element 60 is detachably provided at the end of the first infusion tube 30 away from the connector 20. The sealing element 60 is used to seal the first infusion tube 30.

[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, a sealing element 60 is detachably provided at the end of the second infusion tube 50 away from the connector 20. The sealing element 60 is used to seal the second infusion tube 50.

[0059] In this embodiment, one end of the first infusion tube 30 and the second infusion tube 50 is an outlet, which is connected to the first end 21 of the connector 20. The other end of the first infusion tube 30 and the second infusion tube 50 is an inlet. The inlet is detachably provided with a sealing member 60. This allows the sealing member 60 to block the inlets of the first infusion tube 30 and the second infusion tube 50 when the infusion is paused or the infusion bag is replaced, preventing air, microorganisms or foreign objects from entering the first infusion tube 30 or the second infusion tube 50, thereby reducing the risk of infection for the patient.

[0060] Specifically, the detachable connection between the first infusion tube 30, the second infusion tube 50, and the sealing member 60 can be a threaded connection. That is, an external thread is provided on the outer circumferential surface of the end of the first infusion tube 30 away from the connector 20, while an internal thread is provided in the sealing member 60. This threaded connection between the external and internal threads achieves the threaded connection between the first infusion tube 30, the second infusion tube 50, and the sealing member 60. Alternatively, the sealing member 60 can be sleeved on the outer circumferential surface of the first infusion tube 30 and the second infusion tube 50, achieving a detachable connection between them through friction. Of course, the detachable connection method between the first infusion tube 30, the second infusion tube 50, and the sealing member 60 can be flexibly selected according to actual needs, and this embodiment does not limit it.

[0061] It should be noted that the sealing component 60 can be a heparin cap, which is pre-filled with heparin saline. Utilizing the anticoagulant properties of heparin, it can prevent blood from clotting in the first infusion tube 30 or the second infusion tube 50, ensuring the unobstructed infusion pathway in the first infusion tube 30 and the second infusion tube 50, and facilitating subsequent infusion or drug administration.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the puncture needle fixation device also includes an adjusting member 70, which is connected to the first infusion tube 30 and is used to adjust the flow rate of the liquid in the first infusion tube 30.

[0063] In some embodiments, such as Figure 1 and Figure 2 As shown, the regulating component 70 is connected to the second infusion tube 50 and is used to regulate the flow rate of the liquid in the second infusion tube 50.

[0064] In the embodiments of this application, by providing an adjusting member 70 on the first infusion tube 30 or the second infusion tube 50, not only can the flow rate of the liquid in the first infusion tube 30 and the second infusion tube 50 be adjusted, but the infusion process can also be quickly and temporarily interrupted to perform other clinical operations.

[0065] Specifically, the adjusting component 70 can be either a roller-type stop clamp or a screw-type stop clamp. The roller-type stop clamp adjusts the flow rate during infusion by squeezing the infusion tube with rollers, making operation intuitive and convenient. The screw-type stop clamp gradually compresses the infusion tube by rotating an adjusting screw, allowing for more precise control of the infusion flow rate. Of course, the specific type of adjusting component 70 can be flexibly selected according to actual needs, and this embodiment does not limit its application.

[0066] Optionally, the fixing film 10 has an adhesive layer on the side facing the second end 22, and the adhesive layer surrounds at least a portion of the outer periphery of the connector 20.

[0067] In this embodiment of the application, by providing an adhesive layer on the side of the fixing film 10 facing the second end 22 and by surrounding a portion of the outer periphery of the connector 20 with the adhesive layer, the fixing film 10 can be adhered to the patient's skin surface using the adhesive layer, thereby fixing the puncture needle and preventing problems such as displacement of the puncture needle under the action of external force.

[0068] In other embodiments, a sticker is also provided on the side of the adhesive layer facing the second end 22. The sticker protects the adhesive layer from external impurities that could contaminate it or affect its adhesiveness. It is understood that the sticker can be an easily peelable paper-like film, such as silicone paper or release paper. Before pasting, simply peel off the paper-like film to expose the adhesive layer and then paste it directly.

[0069] Optionally, the fixed film 10 is a flexible transparent film layer.

[0070] In this embodiment of the application, by setting the fixation film 10 as a flexible transparent film layer, the flexible transparent film layer can not only improve the adhesion between the fixation film 10 and the patient's skin, but also allow medical staff to directly observe the skin condition around the puncture point and the position of the puncture needle without removing the fixation film 10. This makes it easier for medical staff to detect abnormalities such as infection or displacement at the puncture site in a timely manner, thus ensuring the safety of the patient.

[0071] Specifically, the flexible transparent film layer can be made of polyurethane, polyethylene, etc. Polyurethane has excellent tensile strength and resilience, allowing the fixation film 10 to adhere more closely to the patient's skin and reducing the risk of the edges of the fixation film 10 lifting or wrinkling due to patient movement. Polyethylene is less expensive, saving costs. Of course, the specific type of flexible transparent film layer can be flexibly selected according to practical needs, and this embodiment does not impose any limitations on it.

[0072] In some embodiments, such as Figure 1As shown, the fixation film 10 can be set as an I-shaped structure, with the narrower part in the middle of the I-shape covering the puncture area, and the wider parts on both sides forming an adhesion area with the patient's skin. This can ensure the firm adhesion between the fixation film 10 and the patient's skin, while also reducing the ineffective adhesion area and improving the patient's comfort.

[0073] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0074] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
