Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and more specifically, to a device for fixing an indwelling needle on a raised platform. Background Technology
[0002] In modern medicine, indwelling catheters are a common medical device widely used in clinical procedures such as intravenous infusion, blood transfusion, and blood sample collection. Their core advantage lies in reducing patient discomfort from repeated punctures, while also lessening the workload of medical staff and improving nursing efficiency. An indwelling catheter typically consists of a stainless steel puncture needle, a flexible catheter, and a plastic needle hub. During use, the flexible catheter is inserted into the patient's vein through the puncture needle, and then the puncture needle is withdrawn, leaving only the flexible catheter for subsequent procedures. To ensure the stability of the indwelling catheter during patient position changes or daily activities, and to prevent catheter displacement or dislodgement, the elevated platform method is commonly used clinically for fixation. This involves using a transparent dressing to tightly adhere the indwelling catheter to the skin, forming a support platform of a certain height to enhance the stability of the fixation.
[0003] However, in practical applications, the stability of the elevated platform fixation method is often affected by various factors, such as the patient's skin characteristics, dressing material, and application technique, resulting in inconsistent fixation effects. Unstable fixation not only increases the risk of indwelling needle displacement and dislodgement but may also cause complications such as local skin irritation and infection, seriously affecting the patient's treatment experience and safety.
[0004] Therefore, we have made improvements to this by proposing a device for fixing an indwelling needle on a raised platform. Utility Model Content

[0013] The arc-shaped strips are fixedly connected to the arc surface of the rotating drum, and the two arc-shaped strips form an arc-shaped channel for the infusion tube to pass through.
[0014] Straight rollers are arranged in the inner wall of the rotating drum along the long side of the drum;
[0015] The tape is wound around a straight roller, with a notch at its free end passing through an arc-shaped channel to the rotating drum;
[0016] A cutting blade is positioned at the notch;
[0017] When the infusion tube is placed on the arc-shaped strip through the arc-shaped channel, the tape is stacked on the infusion tube, and the arc-shaped plate is pressed, causing the tape to be cut by the cutter and forming a raised platform above the arm.
[0018] Preferably, the adhesive surface of the tape faces in the same direction as the arcuate strip to the arcuate channel.
[0019] Preferably, when the axes of the two rotating drums are on the same horizontal plane, there is a gap between their respective arc strips, and the two arc strips are on two different horizontal planes.

[0023] In the scheme of this application:
[0024] To address the issue that the stability of the existing elevated platform fixation method is often affected by various factors, such as patient skin characteristics, dressing material, and application techniques, resulting in inconsistent fixation effects, this application proposes a fixation platform device.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0031] As described in the background section, the stability of the erection platform fixation method is often affected by a variety of factors, such as the patient's skin characteristics, dressing material, and application technique, resulting in inconsistent fixation effects.
[0032] To solve this technical problem, this utility model provides an indwelling needle elevation platform fixation device, which is used to help novice nurses stabilize the platform in an elevated position, while also forming a position for clamping the indwelling needle, preventing excessive dressings from being placed on the patient's skin surface and causing bacterial growth.
[0033] For an example, please refer to... Figure 1 , Figure 2 and Figure 3 A device for fixing an indwelling needle on a raised platform includes a main rod 1;
[0034] Arc plate 2 is slidably connected to the arc surface of the main rod 1, and the adjacent arc plates 2 form an arc for the arm to pass through;
[0035] A coil spring 21 is disposed at the end of the arc-shaped plate 2 away from the rotation side;
[0036] The rotating drum 3 is rotatably connected between two arc-shaped plates 2 with the same arc shape, and its rotation is controlled by the coil spring 21;
[0037] Notch 31 begins on the arc surface of rotating cylinder 3 and connects the inner and outer sides of rotating cylinder 3;
[0038] Arc-shaped strip 32 is fixedly connected to the arc surface of the rotating drum 3, and an arc-shaped channel for the infusion tube to pass through is formed between the two arc-shaped strips 32.
[0039] Straight roller 33 is disposed in the inner wall of rotating drum 3 along the long side of rotating drum 3;
[0040] The tape 4 is wound around the straight roller 33, and its free end passes through the arc-shaped channel of the notch 31 to the rotating drum 3;
[0041] Cutting blade 5 is positioned at notch 31;
[0042] When the infusion tube is set on the arc-shaped strip 32 through the arc-shaped channel, the tape 4 is stacked on the infusion tube, the arc-shaped plate 2 is pressed, and the tape 4 is cut by the cutter 5 and forms a raised platform above the arm.
[0043] In actual use, medical staff need to set the linear direction of the infusion tube in the same direction as the long side of the rotating drum 3. Then, when the infusion tube passes through the notch 31, it contacts the end of the tape 4 and is squeezed by the two tapes 4, so that the ends of the tapes 4 are stacked on the infusion tube, so that the two tapes 4 form a complete line on the infusion tube.
[0044] At this point, the rotating cylinder 3 needs to be placed close to the side of the arm and made to fit the skin surface of the arm. At this time, the arc-shaped strip 32 lifts up the infusion tube and makes the infusion tube and the side of the arm form a raised platform with a certain distance. It should be added that: the raised platform is formed by the adhesive surface of the tape 4 after it wraps around the infusion tube and then sticks to each other and continues to stick to the human body surface, so that the infusion tube is a certain distance from the human body surface. At the same time, since the tape 4 completely wraps the infusion tube, the stability of the infusion tube is greatly improved.
[0045] Then, when the tape 4 is placed until the notch 31 is flush with the horizontal plane, the cutter 5 cuts the tape 4. At this time, the rotating drum 3 is rotated again under the action of the coil spring 21, and the rotating drum 3 gradually moves in the direction of detachment from the arm. At this time, the rotating drum 3 smooths out the tape 4 that has been attached to the skin surface. If it is necessary to insert an indwelling needle, the main rod 1 is pressed to make the arc plate 2 adhere to the skin again without being removed, so that the handle 6 follows the movement of the arc plate 2. This following movement is caused by the arc plate 2 and the handle 6 being fixed to the same bearing, so that the handle 6 acts as a clamp to fix the indwelling needle and prevents too many indwelling needles from being placed on the skin surface, which may lead to bacterial infection.
[0046] The adhesive surface of tape 4 faces the same direction as the arc-shaped strip 32 to the arc-shaped channel.
[0047] When the axes of the two rotating drums 3 are on the same horizontal plane, there is a gap between their respective arc-shaped strips 32, and the two arc-shaped strips 32 are on two different horizontal planes.
[0048] The winding direction of the coil springs 21 of different rotating drums 3 is reversed, which makes it convenient for the tape 4 to be released from the rotating drum 3.
[0049] A handle 6 is fixedly connected to the curved plate 2 and moves with the curved plate 2. The handle 6 is a "U" shaped rod.
[0050] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
