Description

Technical Field

[0001] The present invention relates to the technical field of infusion port needles, and in particular to an ultra-thin infusion port needle. Background Art

[0002] The infusion port needle, also known as the non-destructive needle, is an infusion kit used in conjunction with the infusion port. The main feature of the infusion port needle is that its needle tip is designed as a bevel with a return point, which can avoid the "coring effect", that is, the cut silicone will not block the catheter. This design can also reduce damage to the infusion port puncture membrane and extend the service life of the puncture seat.

[0003] At present, when operating the infusion port needle, medical staff need to pinch the butterfly wings with their fingers and insert the needle body of the infusion port needle into the infusion port. After completion, a fixed film is used to fix the infusion port needle on the patient's skin to prevent the infusion port needle from moving during the infusion process.

[0004] In the prior art, after the infusion port needle is fixed, since components such as the butterfly wings are also located in the fixing film, the fixing film is propped up, so that there is a large distance between a part of the fixing film and the patient's skin, which in turn affects the fixing effect of the fixing film and is prone to puncture infection.

[0005] To this end, we have developed a new ultra-thin infusion port needle. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides an ultra-thin infusion port needle, which solves the problem that the existing fixing film is propped up, resulting in a large distance between a part of the fixing film and the patient's skin, thereby affecting the fixing effect of the fixing film and easily causing puncture infection.

[0008] (II) Technical solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: an ultra-thin infusion port needle, comprising an ultra-thin substrate, a raised slot is fixedly installed on the top of the ultra-thin substrate, an anti-dropping plug is inserted in the raised slot, and a wing plate auxiliary operating member is fixedly connected to one side of the top of the anti-dropping plug;

[0010] The ultra-thin substrate and the raised slot are jointly fixedly embedded with a bent port needle, an infusion tube is jointly fixedly installed between the port needle, the ultra-thin substrate and the raised slot, and an anti-dropping plug sleeve is arranged on the infusion tube;

[0011] An auxiliary soft pad is fixedly installed on the bottom of the ultra-thin substrate.

[0012] Preferably, the raised slot includes a strip-shaped protrusion, and the strip-shaped protrusion is arranged on the top of the ultra-thin substrate. Both sides of the outer surface of the strip-shaped protrusion are fixedly connected to the ultra-thin substrate with an L-shaped plate. The gap formed by the cooperation of the two L-shaped plates, the ultra-thin substrate and the strip-shaped protrusion is the slot body.

[0013] Through the above technical solution, the setting of the L-shaped plate has a travel limit function to ensure the position of the anti-dropping plug-in after insertion.

[0014] Preferably, the strip-shaped protrusions, the ultra-thin base plate and the L-shaped plate are an integrated structure.

[0015] Through the above technical solution, the three components here are integrally formed by injection molding, which ensures the overall strength while improving the processing efficiency.

[0016] Preferably, the anti-dropping plug-in includes two plug-in plates, and the plug-in plates are plugged into adjacent slot bodies, an auxiliary hanging ear is fixedly connected between the two plug-in plates, and a through hole is opened at the center of the auxiliary hanging ear.

[0017] Through the above technical solution, the auxiliary ear is connected to the infusion tube through the through hole, which can prevent the plug-in plate from being completely detached from the infusion port needle after being detached from the slot body, thereby avoiding the need to find additional storage space to place the anti-detachment plug-in and the wing plate auxiliary operating parts.

[0018] Preferably, the wing plate auxiliary operating member includes a connecting seat, and the connecting seat is fixedly installed on one side of the top of the two plug plates, the top of the connecting seat is symmetrically fixedly connected to two supporting seats, the tops of the two supporting seats are fixedly connected with butterfly wings, and the two butterfly wings are provided with anti-slip grooves on the opposite sides.

[0019] Through the above technical solution, the setting of the butterfly wing can facilitate the picking up of the whole during the puncture operation, and the anti-slip pattern can increase the friction of the outer surface of the butterfly wing to avoid slipping during use.

[0020] Preferably, the port needle includes a puncture part, and the auxiliary cushion is sleeved on the outer surface of the puncture part, and the ultra-thin substrate is fixedly sleeved on the top of the outer surface of the puncture part, and the top of the puncture part is fixedly penetrated by a curved part, and the curved part is fixedly embedded in the inner side of the ultra-thin substrate and the strip-shaped protrusion.

[0021] Through the above technical solution, the setting of the curved portion can allow the port needle to be integrated into the ultra-thin substrate and the strip-shaped protrusion, thereby reducing the thickness during fixation and improving the fixing effect of the fixed film.

[0022] Preferably, the infusion tube includes a fixed conical tube, and the fixed conical tube is fixedly embedded in the inner side of the ultra-thin substrate and the strip-shaped protrusion, and fixedly penetrates the bending portion. The end of the fixed conical tube away from the bending portion is fixedly connected to a hose, and the hose is partially fixedly connected to the ultra-thin substrate and the strip-shaped protrusion, and completely penetrates the through hole.

[0023] Through the above technical solution, the arrangement of the tapered tube and the curved portion can achieve the connection between the hose and the puncture portion, which is beneficial for the infusion operation.

[0024] Preferably, the auxiliary soft cushion is made of soft silicone material.

[0025] Through the above technical solution, the auxiliary cushion is made of soft silicone, and one of the main characteristics of soft silicone is its strong softness. While increasing the fit between the auxiliary cushion and the patient's skin, it also increases the overall comfort during use.

[0026] (III) Beneficial effects

[0027] The present invention provides an ultra-thin infusion port needle. It has the following beneficial effects:

[0028] 1. The ultra-thin infusion port needle integrates the local structures of the port needle and the infusion tube into the ultra-thin substrate and the raised slot by designing an ultra-thin substrate, a raised slot, an anti-dropping plug-in, a wing plate auxiliary operating part, a port needle and an infusion tube, and then the wing plate auxiliary operating part and the ultra-thin substrate are designed to be split. After the puncture operation is completed, the wing plate auxiliary operating part is separated from the ultra-thin substrate, and then fixed with a fixed film to avoid the fixed film being propped up high, thereby ensuring the fixed film effect and preventing puncture infection.

[0029] 2. The ultra-thin infusion port needle can prevent the wing plate auxiliary operating part from being completely separated from the infusion port needle through the designed anti-detachment plug-in, which is convenient for subsequent use and does not require additional storage.

[0030] 3. The ultra-thin infusion port needle has a simple auxiliary cushion design, which makes the ultra-thin base plate fit the skin better and improves the fixation effect. At the same time, its softness increases the comfort during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-3 As shown, an embodiment of the present invention provides an ultra-thin infusion port needle, including an ultra-thin substrate 1, a raised slot 3 is fixedly installed on the top of the ultra-thin substrate 1, an anti-dropping plug-in 4 is inserted in the raised slot 3, and a wing plate auxiliary operating part 2 is fixedly connected to one side of the top of the anti-dropping plug-in 4. Through the anti-dropping plug-in 4 and the raised slot 3, the wing plate auxiliary operating part 2 and the ultra-thin substrate 1 are designed to be split.

[0040] The ultra-thin substrate 1 and the raised slot 3 are jointly fixedly embedded with a curved port needle 6, and an infusion tube 5 is jointly fixedly installed between the port needle 6, the ultra-thin substrate 1 and the raised slot 3, and the anti-detachment plug-in 4 is sleeved on the infusion tube 5, so that the port needle 6 and the infusion tube 5 are integrated in the ultra-thin substrate 1 and the raised slot 3, thereby reducing the thickness after fixation and preventing the fixed film from being propped up high.

[0041] An auxiliary soft pad 7 is fixedly installed at the bottom of the ultra-thin substrate 1. The auxiliary soft pad 7 is made of soft silicone material. The setting of the auxiliary soft pad 7 can prevent the ultra-thin substrate 1 from making direct hard contact with the patient's skin when the entire substrate is used, and has a certain protective effect on the patient's skin.

[0042] Figure 4 and Figure 5As shown, the raised slot 3 includes a strip protrusion 303, and the strip protrusion 303 is arranged on the top of the ultra-thin substrate 1, and both sides of the outer surface of the strip protrusion 303 are fixedly connected with the ultra-thin substrate 1 with an L-shaped plate 302, and the gap formed by the two L-shaped plates 302, the ultra-thin substrate 1 and the strip protrusion 303 is the slot body 301, and the strip protrusion 303, the ultra-thin substrate 1 and the L-shaped plate 302 are an integrated structure. The setting of the L-shaped plate 302 can realize the formation of the slot body 301, which is beneficial to the connection between the anti-drop plug-in 4 and the raised slot 3.
