Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for preventing needle stick injury when removing a non-invasive needle of an implanted port. Background Art
[0002] An implanted venous port is a completely implanted vascular access system, which can provide a long-term venous vascular access for patients. During infusion, the butterfly non-invasive needle needs to be replaced regularly. When removing the non-invasive needle of the implanted port, it is necessary to first remove the non-invasive needle. During this process, due to the large resistance of the port base, when the medical staff pulls out the needle vertically, due to inertia, the right hand is prone to rebound back, resulting in needle stick injury.
[0003] For the existing non-invasive needles of implanted ports with rebound protection, the protective cover automatically rebounds when removed to prevent needle stick injury. However, the existing non-invasive needles with rebound devices are relatively expensive and have not been popularized clinically. Currently, ordinary non-invasive needles are still widely used clinically. Content of the Utility Model
[0004] The purpose of the utility model is to provide an auxiliary device for preventing needle stick injury when removing a non-invasive needle of an implanted port in order to solve at least one of the above technical problems.
[0005] In a first aspect, an embodiment of the utility model provides an auxiliary device for preventing needle stick injury when removing a non-invasive needle of an implanted port, including: a pressing plate and a protective plate, wherein the pressing plate and the protective plate are connected by a connecting plate on one side; wherein, the pressing plate and the protective plate are arranged in parallel, and the pressing plate is arranged below the protective plate; the pressing plate is used for pressing the port base by applying pressure with a finger after the finger extends between the pressing plate and the protective plate; the protective plate is used for protecting the pressing finger from being stabbed by the rebounding needle tip of the non-invasive needle when removing the non-invasive needle inserted into the port base.
[0006] Further, the shapes of the pressing plate and the protective plate are both fan-shaped.
[0007] Further, the area of the pressing plate is smaller than the area of the protective plate.
[0008] Further, the connecting plate is an arc-shaped structure.
[0009] Further, the materials of the pressing plate, the protective plate and the connecting plate include plastic plates.
[0010] The utility model provides an auxiliary device for preventing needle stick injury when removing a non-invasive needle of an infusion port. Compared with the existing non-invasive needle with a rebound protective sleeve, the structure is simpler, the cost is lower, and it is easier to popularize in clinics. At the same time, it can avoid the situation that the pressing finger is stabbed by the rebounding needle tip of the non-invasive needle. Brief Description of the Drawings

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0016] Figure 1 It is a three-dimensional view of an auxiliary device for preventing needle stick injury when removing a non-invasive needle of an infusion port provided by an embodiment of the present utility model. As Figure 1 shown, the device includes: a pressing plate 1 and a protective plate 2, and the pressing plate 1 and the protective plate 2 are connected by a connecting plate 3 on one side; wherein, the pressing plate 1 and the protective plate 2 are arranged in parallel, and the pressing plate 1 is arranged below the protective plate 2.
[0017] Specifically, the pressing plate 1 is used to press the base of the infusion port by applying pressure with a finger after the finger extends between the pressing plate 1 and the protective plate 2;
[0018] The protective plate 2 is used to protect the pressing finger from being stabbed by the rebounding needle tip of the non-invasive needle when removing the non-invasive needle inserted into the base of the infusion port.
[0019] Preferably, as Figure 1As shown, the pressing plate 1 and the protection plate 2 are both fan-shaped.
[0020] Preferably, as Figure 1 shown, the connecting plate 3 is an arc-shaped structure.
[0021] Figure 2 is a top view of an auxiliary device for preventing needle stick injury when removing a non-invasive needle of an infusion port according to an embodiment of the present invention. Preferably, as Figure 2 shown, the area of the pressing plate 1 is smaller than the area of the protection plate 2.
