Abstract
Description
Technical Field
[0001] This application relates to the field of medical protective consumables technology, and in particular to a port-of-care needle removal protection device. Background Technology
[0002] A port-a-catheter is a completely implanted, closed intravenous infusion device, primarily composed of an injection port and a venous catheter system. It provides reliable venous access for patients requiring long-term and repeated intravenous treatments. For patients needing frequent infusions, a port-a-catheter eliminates the pain of daily or frequent peripheral venous punctures. For example, a cancer patient undergoing several months of chemotherapy might have to search for a vein in their hand or arm for each infusion without a port-a-catheter, whereas with a port, the puncture is only required at the injection port.
[0003] The external infusion tubing is connected to the infusion port injection seat via a butterfly needle. However, the butterfly needle of current infusion ports is prone to rebounding when withdrawn due to the reaction force. The rebounding butterfly needle can easily prick medical staff, leading to medical infections.
[0004] Therefore, the aforementioned technical defects urgently need to be addressed. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a port-of-care needle removal protection device, which aims to prevent the infusion needle from rebounding and injuring the palm of medical staff when it is pulled out, thereby improving the work safety of medical staff.
[0006] The technical solution adopted by this application to solve the technical problem is as follows: A port-of-care needle removal protection device, comprising:
[0007] A fixing sleeve is used to fix the infusion port base. A first clearance notch is provided on the side wall of the fixing sleeve. The first clearance notch passes through both ends of the fixing sleeve and is used to avoid the infusion needle.
[0008] And a protective cover, which is set at the upper end of the fixed sleeve, and is used to protect the palm of the hand pressing the infusion port base;
[0009] The fixing sleeve and the protective cover are integrally molded.
[0010] In one possible implementation, the fixing sleeve is an elastic fixing sleeve.
[0011] In one possible implementation, an anti-slip layer is provided on the inner wall of the fixed sleeve.
[0012] In one possible implementation, an abutment step is provided at the end of the fixed sleeve facing away from the protective cover, the abutment step being used to abut against the patient's skin surface.
[0013] In one possible implementation, the abutting step and the fixed sleeve are integrally formed, and the abutting step is an elastic step.
[0014] In one possible implementation, the first clearance gap extends to the abutment step, and a second clearance gap is provided on the abutment step, with the first clearance gap and the second clearance gap connecting.
[0015] In one possible implementation, one end of the protective cover is positioned around the circumference of the fixed sleeve.
[0016] In one possible implementation, the protective cover is a curved fan-shaped structure that bends around the axis of the fixed sleeve.
[0017] In one possible implementation, the diameter of the upper port of the fixed sleeve is smaller than the diameter of the lower port of the fixed sleeve.
[0018] Compared with existing technologies, this application provides a protective device for removing IV catheters. In use, medical personnel hold the outer side of the retaining sleeve and place it over the IV catheter. The protective cover then covers the palm. A first clearance notch allows the IV needle to pass through the through-hole of the retaining sleeve. The IV needle is then removed with the other hand. This design prevents the IV needle from rebounding and injuring the medical personnel's hand during removal, thus improving operational safety. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection 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 application based on the specific circumstances.
[0027] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0028] This utility model provides, for example Figure 1 , Figure 2The diagram illustrates a protective device for removing a port-of-care infusion needle, designed to protect the hands of medical personnel and prevent needle sticking and infection during port-of-care removal. The main structure includes a fixing sleeve 1 and a protective cover 2. The fixing sleeve 1 secures the port-of-care base. A through-hole is formed in the fixing sleeve 1. In some embodiments, the through-hole is larger than the port-of-care size so that the fixing sleeve 1 can fit over the port. A first clearance notch 11 is formed on the side wall of the fixing sleeve 1, extending through both ends of the fixing sleeve 1 to allow the infusion needle to pass through. During needle removal, the medical personnel grasp the outer side of the fixing sleeve 1 and move it to the position of the port-of-care. At this time, the infusion tube from the port enters the through-hole of the fixing sleeve 1 through the first clearance notch 11. The fixing sleeve 1 is smoothly placed on the infusion port; the protective cover 2 is set at the upper end of the fixing sleeve 1, and the protective cover 2 is used to protect the palm of the hand pressing the infusion port base; at this time, the palm of the medical staff is isolated from the butterfly needle by the protective cover 2.
[0029] The fixing sleeve 1 and the protective cover 2 are integrally formed. This integral structure makes the structural connection between the fixing sleeve 1 and the protective cover 2 more robust, and also makes production more convenient, faster, and cheaper. Therefore, the protective device in this solution can be used only once, thus further improving the safety of patient infusions.
[0030] It should be noted that current infusion port butterfly needles are prone to rebounding when withdrawn due to the reaction force, which can easily injure medical staff and lead to medical infections. In this invention, the medical staff holds the outer side of the fixing sleeve 1 and places it over the infusion port. At this time, the protective cover 2 covers the palm. The first clearance notch 11 avoids the infusion needle, allowing it to enter the through-hole of the fixing sleeve 1. Once the fixing sleeve 1 is in place, the medical staff can control the gripping force to deform the fixing sleeve 1, causing deformation of its inner side, thus securing the infusion port. Then, the infusion needle is withdrawn with the other hand. When the butterfly needle rebounds due to the reaction force, it is stopped by the protective cover 2. This prevents the rebounding needle from injuring the medical staff's palm and improves their operational safety.
[0031] Furthermore, the fixation sleeve 1 is an elastic fixation sleeve. The fixation sleeve 1 is made of an elastic material structure. Medical staff can control the clamping force of their fingers to deform the fixation sleeve 1, causing the inner side of the fixation sleeve 1 to deform, thereby securing the infusion port.
[0032] Furthermore, such as Figure 2 , Figure 3As shown, an anti-slip layer 12 is provided on the inner wall of the fixing sleeve 1. When the fixing sleeve 1 deforms to clamp the main infusion port, the anti-slip layer 12 can increase the friction between the inner wall of the fixing sleeve 1 and the skin above the infusion port. This allows the fixing sleeve to effectively fix the fixing sleeve 1.
[0033] Furthermore, such as Figure 2 , Figure 3 As shown, the end of the fixing sleeve 1 facing away from the protective cover 2 is provided with an abutment step 3, which is used to abut against the patient's skin surface. After the fixing sleeve 1 is in place, the abutment step 3 abuts against the patient's skin around the infusion port, thereby increasing the contact area between the fixing sleeve 1 and the patient's skin and avoiding pressure marks on the patient's skin during the needle removal process.
[0034] Furthermore, such as Figure 2 , Figure 3 As shown, the abutment step 3 and the fixing sleeve 1 are integrally formed, and the abutment step 3 is an elastic step. The elastic step can further buffer the stress between the step and the patient's skin, further avoiding pressure marks on the patient's skin.
[0035] Furthermore, such as Figure 2 , Figure 3 As shown, the first clearance notch 11 extends to the abutment step 3, and the abutment step 3 has a second clearance notch 31, which connects to the first clearance notch 11. It can be understood that the infusion tube on the infusion port enters the through hole of the fixing sleeve 1 through the first clearance notch 11 and the second clearance notch 31. This allows the fixing sleeve 1 to be smoothly positioned and secure the infusion port.
[0036] Furthermore, one end of the protective cover 2 is arranged around the circumference of the fixed sleeve 1.
[0037] Furthermore, such as Figure 2 , Figure 3 As shown, the protective cover 2 is a curved fan-shaped structure that bends around the axis of the fixed sleeve 1. By surrounding the butterfly needle on the infusion port with the curved fan-shaped structure, the effective protection range of the protective cover 2 is improved.
[0038] Furthermore, the diameter of the upper port of the fixing sleeve is smaller than the diameter of the lower port of the fixing sleeve. Also, the diameter of the upper port of the fixing sleeve is smaller than the size of the infusion port. This is to prevent medical personnel from accidentally pulling out the infusion port during needle removal.
[0039] In summary, this application provides a protective device for removing IV port needles. When using this device, medical personnel hold the outer side of the fixing sleeve 1 and place it over the IV port. At this time, the protective cover 2 covers the palm. The first clearance notch 11 avoids the IV needle, allowing it to enter the through hole of the fixing sleeve 1. Then, the other hand is used to remove the IV needle. This prevents the IV needle from rebounding and injuring the medical personnel's palm when it is removed, thus improving the safety of medical personnel during operation.
[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
