Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of medical device technology, and more specifically, to an infusion port needle. Background Technology

[0002] Currently used intravenous access ports (IAPorts) exhibit several significant drawbacks in clinical practice. When the doctor inserts the port and releases their hand, the flaps, being made of flexible material, gradually retract. This forces the doctor to continuously hold the flaps in place after insertion, affecting subsequent steps such as applying adhesive tape for fixation. Furthermore, when removing the port, the doctor must re-pinch the flaps, making the process inconvenient. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide an infusion port needle, which solves the technical problem of inconvenience in the use of infusion port needles in related technologies.

[0004] According to one aspect, at least one embodiment of this disclosure provides an infusion port needle, comprising: a kit, one end of which is used to communicate with a tubing and the other end of which is used to communicate with a needle, the kit having at least two first support portions located on both sides of the kit;

[0005] The butterfly wing has two wings, which are respectively arranged on both sides of the kit and are flexible, bending towards one side of the kit under external force. The butterfly wing has a stop portion.

[0006] The first support is located on the moving path of the abutment during the bending of the butterfly wing. After the two butterfly wings bend and approach each other, the abutment engages with the upper part of the first support.

[0007] For example, in an infusion port needle provided in at least one embodiment of this disclosure, the first support portion has two sets, each set having at least one first support portion, and the two sets of first support portions are respectively located on both sides of the kit.

[0008] For example, in an infusion port needle provided in at least one embodiment of this disclosure, each group has two first support portions, and the two first support portions have an accommodating space and an opening that are interconnected.

[0009] The width of the accommodating space is greater than the width of the abutment, and is used to accommodate the abutment;

[0010] The width of the opening is smaller than the width of the abutment. After the butterfly wing bends, the abutment passes through the opening, and its two ends are respectively engaged with the upper parts of the two first support parts in a set.

[0011] For example, in an infusion port needle provided in at least one embodiment of this disclosure, the end of the first support portion near the port has an arc-shaped structure;

[0012] The portion of the abutment that abuts against the first support portion has a frustum structure.

[0013] For example, in an infusion port needle provided in at least one embodiment of this disclosure, the kit further has at least two second support portions, which are flexible and located below the first support portion for contact with the skin.

[0014] For example, in an infusion port needle provided in at least one embodiment of this disclosure, there are four second support portions, and the four second support portions are located below the four first support portions in a one-to-one correspondence.

[0015] For example, in an infusion port needle provided in at least one embodiment of this disclosure, the kit further has a slot located above the second support portion to provide deformation space for the second support portion.

[0016] For example, in an infusion port needle provided in at least one embodiment of this disclosure, there is a gap between two adjacent second support portions.

[0017] For example, in an infusion port needle provided in at least one embodiment of this disclosure, the bottom of the second support portion has an arc-shaped structure.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the first support portion supports the entire butterfly wing through its abutment, maintaining the stability of the butterfly wing's shape and facilitating the subsequent application of adhesive tape to secure the infusion port needle. Medical staff can more easily apply the tape to the appropriate position without worrying about the butterfly wing's position affecting the tape's adhesion, thus improving the efficiency and quality of tape application and further enhancing the fixation effect of the infusion port needle. During subsequent needle removal, due to the butterfly wing design, medical staff can simply squeeze the butterfly wing to complete the removal operation, improving convenience.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

Therefore, they should not be construed as limitations on this disclosure.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-3 As shown, an infusion port needle according to an embodiment of the present disclosure includes: a kit 1, one end of which is used to communicate with a tubing 2 and the other end is used to connect with a needle 3. The kit 1 has at least two first support portions 101, which are respectively located on both sides of the kit 1; two butterfly wings 4, which are respectively disposed on both sides of the kit 1 and are flexible, bending towards one side of the kit 1 under external force. The butterfly wings 4 have abutment portions 401; the first support portions 101 are located on the movement path of the abutment portions 401 during the bending of the butterfly wings 4. After the two butterfly wings 4 bend and approach each other, the abutment portions 401 engage with the upper part of the first support portions 101.

[0032] For example, one end of the kit 1 is connected to the liquid tube 2 and the other end is connected to the needle 3, so that the liquid in the liquid tube 2 can be smoothly guided to the needle 3 and then injected into the infusion port in the patient's body.

[0033] The butterfly wing 4 is flexible and is generally made of flexible medical-grade plastic material, such as polycarbonate and polypropylene. Some are made of silicone rubber. It can bend to one side of the kit 1 under the action of external force. The abutment 401, which is integrated with the butterfly wing 4, is also flexible. In actual use, the two butterfly wings 4 are pinched together with both hands to hold the port needle firmly and then the needle 3 is inserted into the infusion port. During the bending process of the butterfly wing 4, the abutment 401 first abuts against the lower part of the first support 101. With slight force from the doctor, the butterfly wing 4 bends further, causing the abutment 401 to bend under the resistance of the first support 101. The abutment 401 passes through the first support 101 on one side and is positioned above it. After the doctor inserts the needle 3 into the port seat of the infusion port, the butterfly wing 4 is released. At this point, the abutments 401 of the two butterfly wings 4 respectively engage with the upper parts of the first support 101 located on both sides of the kit 1. The first support 101 supports the entire butterfly wing 4 through the abutments 401, maintaining the stability of the butterfly wing 4's shape and facilitating subsequent application of adhesive tape to fix the infusion port needle. Medical staff can more easily apply the adhesive tape in the appropriate position without worrying about the positional changes of the butterfly wing 4 affecting the tape's adhesion, thus improving the efficiency and quality of tape application and further enhancing the fixation effect of the infusion port needle. During subsequent needle removal, thanks to the design of the butterfly wing 4, medical staff can simply squeeze the butterfly wing 4 to complete the needle removal operation, which improves convenience.

[0034] In some examples, the first support 101 has two sets, each set having at least one first support 101, and the two sets of first support 101 are located on both sides of the kit 1.

[0035] For example, the first support 101 adopts a design with two sets of symmetrically distributed on both sides of the kit 1, which makes the force on the whole device more uniform and improves the stability and durability of the device.

[0036] In some examples, each group has two first support portions 101, and the two first support portions 101 have an interconnected receiving space 102 and an opening 103; the width of the receiving space 102 is greater than the width of the abutment 401, and is used to receive the abutment 401; the width of the opening 103 is less than the width of the abutment 401, and after the butterfly wing 4 bends, the abutment 401 passes through the opening 103, and its two ends are respectively engaged with the upper part of the two first support portions 101 of the group.

[0037] For example, in its initial state, the abutment 401 is located within the receiving space 102. The receiving space 102 provides initial positional limitation for the abutment 401. During infusion, the butterfly wing 4 bends, and the abutment 401 moves from the receiving space 102 toward the opening 103. After further deformation, it passes through the opening 103 and enters the upper part of the opening 103, where it engages with the upper part of the two first support parts 101. The receiving space 102 and the opening 103 provide a channel for the movement of the abutment 401 and, through the limiting effect of the opening 103, achieve accurate engagement between the abutment 401 and the first support parts 101, making the fit of the entire structure more tight and reasonable.

[0038] In some examples, the end of the first support portion 101 near the opening 103 is arc-shaped; the portion of the abutment portion 401 that abuts against the first support portion 101 is frustoconical.

[0039] For example, such as Figure 3 As shown, when the butterfly wing 4 bends under external force, and the abutment 401 approaches the first support 101 and prepares to pass through the opening 103, the arc-shaped end of the first support 101 near the opening 103 acts as a guide. The arc-shaped design allows the abutment 401 to move more smoothly along the arc-shaped surface when it contacts the first support 101, avoiding jamming or deviation of the abutment 401 during movement and ensuring the smoothness of the bending process of the butterfly wing 4.

[0040] The frustum structure of the abutment 401 has a certain inclination angle, which provides further guidance when it mates with the arc-shaped end of the first support 101. When the abutment 401 approaches the first support 101, the inclined surface of the frustum can better fit with the arc-shaped end, guiding the abutment 401 to accurately pass through the through 103 and reach the position where it engages with the upper part of the first support 101, thus improving the accuracy and efficiency of the engagement.

[0041] In some examples, kit 1 also has at least two second support portions 104, which are flexible and located below the first support portion 101 for contact with the skin.

[0042] For example, such as Figure 2 and Figure 3 As shown, the second support 104 is flexible, allowing it to naturally conform to the undulations and curvature of the skin surface and adapt to the shape of the human skin, providing additional support points for the entire infusion port needle. The first support 101 is mainly used to support the butterfly wing 4, while the second support 104, through contact with the skin, distributes part of the weight of the device onto the skin, reducing the pressure on the contact point between the needle 3 and the skin, and also helps to stabilize the position of the entire device, preventing unnecessary shaking or displacement during infusion.

[0043] In some examples, there are four second support portions 104, with each of the four second support portions 104 located below one of the four first support portions 101.

[0044] For example, such as Figure 2 and Figure 3 As shown, the four second support portions 104 form a multi-point support stable structure, providing support to the infusion port needle from multiple directions. This structure can better resist external forces from various directions, such as shaking caused by slight patient movement or the impact force from fluid flow during infusion, ensuring the infusion port needle maintains a stable position throughout the infusion process, greatly reducing the risk of needle displacement and leakage, and improving the safety and reliability of infusion. The one-to-one correspondence between the second support portions 104 and the first support portion 101 makes their synergistic effect more efficient. The first support portion 101 stabilizes the butterfly wing 4, while the second support portions 104 provide a stable foundation for the first support portion 101 from below, further enhancing the stability of the entire device.

[0045] The four secondary support sections 104 evenly distribute the weight and pressure of the device onto the skin surface, preventing excessive pressure on any particular area. Compared to designs with a single or few support points, multi-point support allows for a more even pressure distribution, reducing pain and discomfort caused by localized pressure on the skin.

[0046] In some examples, kit 1 also has a slot 105 located above the second support 104 to provide space for deformation of the second support 104.

[0047] For example, such as Figure 2 and Figure 3 As shown, because the groove 105 provides deformation space, the second support 104 can more fully conform to various irregular contours of human skin. The surface of human skin is not completely flat, but has varying degrees of undulation and curvature. The groove 105 allows the second support 104 to deform according to actual conditions, making the contact between the second support 104 and the skin tighter and more stable. This effectively reduces the shaking and displacement of the infusion port needle during use, ensuring that the needle 3 can be accurately held in the infusion position, improving the safety and reliability of infusion.

[0048] In some examples, there is a gap between two adjacent second support portions 104.

[0049] For example, the presence of the gaps allows each second support portion 104 to be relatively independent when subjected to external force and undergoing deformation. When a second support portion 104 deforms upon contact with a protrusion or depression in the skin, the deformation will not be directly transmitted to or affect adjacent second support portions 104 due to the isolation provided by the gaps. Each second support portion 104 can independently perform deformation actions such as bending up and down according to the actual skin conditions at its location, thereby more precisely conforming to the skin surface.

[0050] In some examples, the bottom of the second support 104 has an arc-shaped structure.

[0051] For example, the curved structure at the bottom of the second support portion 104 can better match the curvature of the skin. When the second support portion 104 comes into contact with the skin, the curved bottom can adaptively adjust according to the natural shape of the skin to achieve a tighter and more comprehensive fit, making the contact between the two more uniform.

[0052] In some examples, it also includes: a heparin cap 5, which is disposed at one end of the liquid tube 2.

[0053] For example, the main function of the heparin cap 5 is to seal one end of the infusion tubing 2. When the infusion process is paused or ended, the heparin cap 5 prevents external contaminants such as air and bacteria from entering the interior of the tubing 2, maintaining a relatively sterile environment inside the tubing 2. It is tightly connected to the end of the tubing 2, forming a sealed space that prevents the intrusion of external substances. After the infusion is completed, a sealing solution such as heparinized saline is usually used to prevent blood from flowing back into the tubing 2 and causing blockage. At this time, medical staff can use a syringe to inject the sealing solution into the tubing 2 through the heparin cap 5. The heparin cap 5 has a special structure inside (such as a rubber diaphragm). When the syringe needle punctures the tubing, the diaphragm will temporarily open, allowing the sealing solution to enter; when the needle is withdrawn, the diaphragm will automatically spring back to restore the seal, ensuring the sealing of the tubing 2.

[0054] It should be noted that titanium alloy is a preferred material for the perineal needle to ensure that patients can safely undergo MRI examinations while the perineal needle is in place.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
