Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an indwelling needle anti-lifting dressing. Background Technology
[0002] In clinical settings, indwelling needles are widely used in the treatment of various diseases because they reduce the pain of repeated punctures and facilitate long-term intravenous infusion. With the development of medical monitoring technology, the combined use of indwelling needles and sensors is becoming increasingly common. By connecting sensors to the indwelling needle, important physiological parameters such as blood pressure and blood oxygen can be monitored in real time, providing crucial data support for clinical diagnosis and treatment. However, the existing connection structure between the indwelling needle and the sensor has significant problems. The connection part between the indwelling needle and the sensor is large in volume and has irregular protrusions on the surface. In actual use, these protrusions create large gaps between the indwelling needle and the patient's skin, making it difficult for traditional dressings to adhere tightly. Conventional dressings mostly use a flat adhesive tape design, and their fixation principle mainly relies on the adhesion between the pressure-sensitive adhesive and the skin surface. However, for the protrusions at the connection part between the indwelling needle and the sensor, flat dressings cannot provide effective wrapping and restraint. When the patient performs hand movements, such as bending or grasping, the protrusions are easily subjected to external forces.
[0003] Under external force, indwelling needles may move or tilt. Once the indwelling needle moves, it may not only lead to inaccurate monitoring data and affect medical judgment; if the indwelling needle tilts severely, it may also cause the edge of the dressing to gradually separate from the skin, resulting in the failure of the dressing to stay in place. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing an anti-lifting dressing for indwelling needles. It effectively solves the problem of difficulty in fixing the dressing at the connection point between the indwelling needle and the sensor due to the special structure, preventing the indwelling needle from lifting and shifting, and improving the safety and stability of indwelling needle use.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An indwelling needle anti-lifting dressing includes a dressing body, the dressing body being provided with a fastener for positioning the indwelling needle, and the dressing body also being provided with a fixing piece and a reinforcing piece for further fixing the indwelling needle positioned on the fastener.
[0006] Preferably, the main body of the dressing is provided with symmetrical reinforcing wings on both sides. The reinforcing wings themselves have a certain degree of elasticity and flexibility, which can adapt to the movement of the limbs, disperse the external forces generated in various directions, and improve the adhesion effect of the dressing.
[0007] Preferably, the fastener includes a fixing plate, and the fixing plate is provided with an arc-shaped clamping plate for holding the indwelling needle. The fixing plate is fixed to the dressing body, and the arc-shaped clamping plate can closely fit the surface contour of the indwelling needle. When the indwelling needle is placed in the arc-shaped clamping plate, it can be accurately clamped and constrained.
[0008] Preferably, there are two fixing pieces, which are respectively located on the front and rear sides of the dressing body. One end of the fixing piece is fixedly connected to the dressing body. When the fixing piece is attached to the front and rear ends of the indwelling needle, it uses its own adhesive layer to tightly adhere to the surface of the indwelling needle and the dressing body, forming a strong constraint structure, which can effectively prevent the two ends of the indwelling needle from lifting up.
[0009] Preferably, the reinforcing plate is located in the middle of the dressing body, and one end of the reinforcing plate is fixedly connected to the dressing body. Placing the reinforcing plate in the middle of the dressing body is a further strengthening measure for fixing the indwelling needle. During the fixing process of the indwelling needle, although the fastener positions it in the circumferential direction and the fixing plate constrains the front and rear ends, the middle of the indwelling needle may still be unstable due to external force, such as lifting. The reinforcing plate is specifically designed to address this problem. When the reinforcing plate is attached to the middle of the indwelling needle, it works together with the fastener and the fixing plate to form a comprehensive and multi-layered fixing system.
[0010] Preferably, the dressing body, the fixing piece, and the reinforcing piece are all provided with an adhesive layer, and the adhesive layer is provided with a dustproof paper to prevent dust contamination. The adhesive layer has good adhesion, which can firmly stick the various parts of the dressing to the skin surface and the indwelling needle. The dustproof paper can protect the adhesive layer before use. During the storage and transportation of the dressing, the dustproof paper can effectively prevent dust, impurities and other pollutants from coming into contact with the adhesive layer.
[0011] Compared with the prior art, the present invention has the following beneficial effects: The indwelling needle anti-lifting dressing provided by this utility model improves the stability of the dressing by symmetrically reinforcing wings on both sides of the dressing body to disperse external forces. The fasteners can hold the indwelling needle in place and limit its movement. Two fixing plates constrain the front and rear ends, and the reinforcing plates strengthen the middle fixation, forming an all-round fixation system that can effectively prevent the indwelling needle from lifting and shifting.

Example
[0019] Please see Figure 1-4 An indwelling needle anti-lifting dressing includes a dressing body 1, a fastener 3 for positioning the indwelling needle on the dressing body 1, and a fixing piece 4 and a reinforcing piece 5 for further fixing the indwelling needle positioned on the fastener 3 on the dressing body 1.
[0020] The main body of the dressing 1 is provided with symmetrical reinforcing wings 2 on both sides. The reinforcing wings 2 have a certain degree of elasticity and flexibility, which can adapt to the movement of the limbs, disperse the external forces generated in various directions, and improve the adhesion effect of the dressing.
[0021] The fastener 3 includes a fixing plate 31, on which an arc-shaped clamping plate 32 is provided to hold the indwelling needle. The fixing plate 31 is fixed on the dressing body 1. The arc-shaped clamping plate 32 can closely fit the surface contour of the indwelling needle. When the indwelling needle is placed in the arc-shaped clamping plate 32, it can be accurately clamped and constrained.
[0022] Two fixing pieces 4 are provided, and the two fixing pieces 4 are respectively located on the front and rear sides of the dressing body 1. One end of the fixing piece 4 is fixedly connected to the dressing body 1. When the fixing piece 4 is attached to the front and rear ends of the indwelling needle, it uses its own adhesive layer 6 to tightly adhere to the surface of the indwelling needle and the dressing body 1, forming a strong constraint structure, which can effectively prevent the two ends of the indwelling needle from lifting up.
[0023] The reinforcing plate 5 is located in the middle of the dressing body 1. One end of the reinforcing plate 5 is fixedly connected to the dressing body 1. Setting the reinforcing plate 5 in the middle of the dressing body 1 is a further strengthening measure for fixing the indwelling needle. During the fixing process of the indwelling needle, although the fastener 3 positions it in the circumferential direction and the fixing plate 4 constrains the front and rear ends, the middle part of the indwelling needle may still be unstable due to external force, such as lifting. The reinforcing plate 5 is specifically designed to address this problem. When the reinforcing plate 5 is attached to the middle of the indwelling needle, it works together with the fastener 3 and the fixing plate 4 to form a comprehensive and multi-layered fixing system.
[0024] The main body 1, the fixing plate 4, and the reinforcing plate 5 are all provided with an adhesive layer 6. The adhesive layer 6 is covered with a dustproof paper 7 to prevent dust contamination. The adhesive layer 6 has good adhesion, which can firmly stick the various parts of the dressing to the skin surface and the indwelling needle. The dustproof paper 7 can protect the adhesive layer 6 before use. During the storage and transportation of the dressing, the dustproof paper 7 can effectively prevent dust, impurities and other pollutants from coming into contact with the adhesive layer 6.
[0025] In the manufacturing process of this utility model, the dressing body 1 is made of soft, breathable medical material, cut and shaped according to the design dimensions to form the basic shape of the dressing body 1. Reinforcing wings 2 are symmetrically glued or integrally formed on both sides of the dressing body 1 to ensure a firm connection between the reinforcing wings 2 and the dressing body 1, while also possessing a certain degree of elasticity and flexibility to accommodate limb movement. A fixing plate 31 is fixed to a predetermined position on the dressing body 1. Then, an arc-shaped clamping plate 32, adapted to the shape of the indwelling needle, is installed on the fixing plate 31 through welding... Adhesion or other suitable fixing methods ensure that the arc-shaped clamping plate 32 is firmly connected to the fixing plate 31 and can reliably hold the indwelling needle. On the front and rear sides of the dressing body 1, one end of the fixing piece 4 is fixedly connected to the dressing body 1. Adhesion or hot pressing can be used to ensure that the fixing piece 4 can be flexibly flipped and attached to the front and rear ends of the indwelling needle. In the middle position of the dressing body 1, one end of the reinforcing piece 5 is fixedly connected to the dressing body 1. Similarly, a suitable fixing method can be used to ensure that the reinforcing piece 5 can effectively fix the middle of the indwelling needle. When using this indwelling needle anti-lifting dressing, medical staff first remove the dustproof paper 7 from the dressing body 1, then expose the adhesive layer on the dressing body 1. Align the adhesive layer on the dressing body 1 with the back of the patient's hand, and attach the dressing body 1 to the back of the patient's hand. Align the indwelling needle with the fastener 3. The curved clamp 32 can hold the indwelling needle in place, preventing it from shifting. Then, remove the dustproof paper 7 from the two fixing plates 31 and the reinforcing plate 5. Flip the reinforcing plate 5 and attach it to the front and rear ends of the indwelling needle. Use the adhesive layer 6 to firmly attach the fixing plate 4 to the surface of the indwelling needle and the dressing body 1 to fix the front and rear ends of the indwelling needle. Flip the reinforcing plate 5 and attach it to the middle of the indwelling needle to further fix the indwelling needle. This ensures that the indwelling needle is in a stable position within the dressing and will not lift or shift.
[0026] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
