Technical Field

[0001] This utility model relates to the field of butterfly needle fixation, specifically to a butterfly needle fixation device for infusion ports. Background Technology

[0002] A butterfly-shaped infusion needle is a non-invasive needle specifically designed for infusion ports, typically named for its butterfly shape. This needle is primarily used for inserting a fully implantable intravenous access port (TIVAP) to facilitate long-term or intermittent medical treatments and drug infusions. It offers advantages such as easy installation, convenient maintenance, and minimal pain, and is widely used in hospital clinical practice. The butterfly needle consists of four parts: the needle body, the needle hub, the needle wings, and the push rod. The needle wings are the main structural component, and infusion is achieved by rotating the push rod.

[0003] A search revealed a Chinese patent with patent number CN215690593U, which discloses a novel dressing for fixing a butterfly needle for an infusion port. The butterfly needle fixing layer has a circular hole in the middle for fixing the injection seat inside the protruding skin, which can avoid the operation of padding with sterile cotton. The butterfly needle fixing layer also has a groove located below the circular hole to match the catheter. The dressing layer has a protrusion in the middle, and the interior of the protrusion forms a receiving chamber for accommodating the protruding skin at the implanted infusion port.

[0004] The existing technology has the following problems: the circular hole is aligned with the raised part of the skin, which cannot absorb blood and exudate in time; the groove is located below the circular hole but is not connected, which makes the butterfly needle unstable and has a poor effect in preventing the butterfly needle from shifting; the protrusion in the middle of the dressing layer cannot adapt well to the complex structure of the upper part of the butterfly needle, resulting in poor dressing flatness. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0037] In practice, the inventors discovered that the existing circular holes are aligned with the raised parts of the skin, which cannot absorb blood and fluid in time; the grooves are located below the circular holes but are not connected, which makes the butterfly needle unstable and has a poor effect in preventing the butterfly needle from shifting; the protrusions in the middle of the dressing layer cannot adapt well to the complex structure of the upper part of the butterfly needle, resulting in poor dressing flatness.

[0038] Based on the above findings, this application proposes an infusion port butterfly needle fixation device that can absorb blood and fluid leakage in a timely manner, provides good butterfly needle fixation, and ensures excellent dressing flatness. Example

[0039] See Figures 1-7 This application discloses an infusion port butterfly needle fixation device, including an adsorption fixation layer 1 and an adhesive layer 2, wherein the adsorption fixation layer 1 is disposed above the adhesive layer 2 and the butterfly needle infusion set is sandwiched in the middle.

[0040] The lower surface of the adsorption and fixing layer 1 is coated with pressure-sensitive adhesive (not shown in the figure), and release paper 106 is covered on the pressure-sensitive adhesive. A butterfly needle fixing groove is provided in the middle of the adsorption and fixing layer 1. The butterfly needle fixing groove includes a needle body fixing groove 102, a guide tube fixing groove 103, and a butterfly wing hole 101. The guide tube fixing groove 103 is connected and located directly below the needle body fixing groove 102. The two are on the same axis to ensure that the butterfly needle can be stably placed in the adsorption and fixing layer 1. The butterfly wing hole 101 is symmetrically arranged about the needle body fixing groove 102 to ensure a good butterfly needle fixing effect. The needle body fixing groove 102 has a needle hole 104 at the top. The needle hole 104 passes through the absorbent fixing layer 1 and is tangential to the needle body fixing groove 102. A receiving cavity 105 is opened below the absorbent fixing layer 1. The receiving cavity 105 is connected to the needle body fixing groove 102 through the needle hole 104. A thin absorbent fixing layer 1 is left at the intersection of the receiving cavity 105 and the needle body fixing groove 102. The thin absorbent fixing layer 1 is set on the protruding part of the patient's skin, which can absorb blood and exudate in time.

[0041] When in use, the butterfly needle and infusion tubing of the butterfly needle infusion set are placed in the corresponding positions of the butterfly needle fixing slot. That is, the butterfly needle tip is inserted into the infusion port after passing through the needle tip hole 104, the butterfly needle wings are placed in the butterfly wing holes 101, the butterfly needle body is placed in the needle body fixing slot 102, and the infusion tubing is placed in the tubing fixing slot 103.

[0042] The adsorption and fixation layer 1 is made of a soft, skin-friendly, breathable, and water-absorbing material with a thickness of 2-3cm, preferably a medical sponge or hydrocolloid, which can absorb the sweat of the skin and prevent the butterfly needle fixation layer 1 from detaching from the skin due to being soaked in sweat.

[0043] The cavity 105 is not coated with pressure-sensitive adhesive and has a size of 2.5~3cm, which matches the size of the injection seat in the infusion port.

[0044] The second dressing layer is made of large 3M dressing, measuring 15cm × 10cm. The main components of 3M dressing include non-woven absorbent pad, polyethylene perforated isolation layer, non-woven backing, adhesive, and release paper, ensuring the sterility of the dressing and a good user experience. In addition, 3M dressing also includes water-based adhesive, covering film (polyurethane), adhesive (acrylate), and other components to meet the needs of different wound types. Large 3M dressing is an existing product and will not be described in detail here.

[0045] Specifically, the dressing layer 2 has a butterfly needle through-hole 201 in the middle, allowing the upper part of the butterfly needle to pass through it. In use, the butterfly wing is fitted into the wing hole 101 and fixed by the dressing layer 2. The upper part of the butterfly needle passes through the through-hole, which adapts well to the complex structure of the upper part of the butterfly needle, making the dressing layer 2 flatter. Below the butterfly needle through-hole 201 is a catheter through-hole 202. The infusion catheter of the butterfly needle infusion set passes through the catheter through-hole 202, and there is a certain distance between the catheter through-hole 202 and the butterfly needle through-hole 201. This part can fix the infusion catheter, further enhancing the fixation effect of the butterfly needle. After the infusion catheter passes through the catheter through-hole 202, it is connected to the infusion switch 4, and finally the infusion catheter is fixed in the fixing clip 5.

[0046] The fixing clip 5 is attached to one side above the dressing layer 2 and is used to fix the infusion tubing of the butterfly needle infusion set.

[0047] One usage process of this embodiment is as follows:

[0048] Remove the release paper 106 from the absorbent fixation layer 1. Align the receiving cavity 105 with the convex part of the skin and attach the absorbent fixation layer to the skin, leaving no gap between the absorbent fixation layer 1 and the skin. Place the butterfly needle and infusion tubing of the butterfly needle infusion set into the corresponding positions of the butterfly needle fixing slot and press gently to ensure that the butterfly needle is properly installed in the absorbent fixation layer 1. Then, remove the release paper from the dressing layer 2 and pass the butterfly needle infusion tubing and infusion switch 4 through the tubing through hole 202. That is, the butterfly needle is on the adhesive side of the dressing layer 2, and the infusion tubing and infusion switch 4 are on the other side of the dressing layer 2. Then, let the upper part of the butterfly needle pass through the butterfly needle through hole 201 of the dressing layer 2 and stick the dressing layer 2 to the absorbent fixation layer 1 and the patient's skin. Gently press and smooth the dressing layer 2 so that the adhesive on the lower surface of the dressing layer 2 adheres to the upper part of the absorbent fixation layer 1 and the skin, forming a sealed environment.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
