Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and more specifically, to a fixation device for extracorporeal membrane oxygenation (ECMO) tubing. Background Technology

[0002] Extracorporeal membrane oxygenation (ECMO) technology provides crucial extracorporeal circulatory support for critically ill patients with severe acute respiratory failure, playing a vital role as a life-saving measure, especially in the treatment of acute respiratory distress syndrome (ARDS). In my country, the most widely used ECMO cannulation mode currently involves right femoral vein drainage and right jugular vein blood return. This mode requires the ECMO tubing to remain stable within the patient for an extended period (usually 1-2 weeks or longer) to ensure it does not dislodge or shift during patient movement, turning, or agitation, thus guaranteeing the continuity and safety of treatment.

[0003] However, current clinical practice primarily relies on skin sutures combined with extensive use of tape and adhesive films to secure the ECMO tubing to the patient's head, neck, and legs. This method is not only cumbersome, but the adhesive strength of the tape gradually weakens over time, leading to decreased fixation effectiveness. Furthermore, because the tubing needs to be repositioned as treatment progresses and the patient's condition changes, or adjusted for skin care and ventilation requirements, healthcare professionals must frequently remove and reapply the tape. This process is not only time-consuming and labor-intensive but can also damage the patient's skin and the tubing, increasing the risk of infection.

[0004] Therefore, there is an urgent need for a comfortable and convenient fixation device for extracorporeal membrane oxygenation (ECMO) tubing. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, such as cumbersome operation and a significant decrease in fixation effect after long-term use, this utility model provides a fixation device for extracorporeal membrane oxygenation (ECMO) tubing.

[0006] The technical solution of this utility model is as follows: This utility model provides a fixing device for extracorporeal membrane oxygenation (ECMO) tubing, including a fixing belt, a first fixing block, a first connecting block, a second connecting block, a second fixing block, and a spiral spring. The fixing belt is provided with the first fixing block, the first connecting blocks are installed on both sides of the first fixing block, the spiral spring is sleeved on the first connecting block, the second connecting block is sleeved on the spiral spring, and the second fixing block is connected to the second connecting block.

[0007] Preferably, it also includes a first hook and loop fastener and a second hook and loop fastener, with the first hook and loop fastener provided on one end of the fastener and the second hook and loop fastener provided on the reverse side of the other end, and the first hook and loop fastener and the second hook and loop fastener are movably attached.

[0008] Preferably, it also includes a first rubber pad, and the first rubber pad is attached to both the first fixing block and the second fixing block.

[0009] Preferably, it further includes a third connecting block, on which the second connecting block is connected.

[0010] Preferably, it also includes a second rubber pad, which is attached to the fixing strap.

[0011] Preferably, the fixing strap, the first Velcro, the second Velcro, and the second rubber pad are provided with a large number of ventilation holes.

[0012] The beneficial effects of this utility model are: This invention utilizes a spiral spring to automatically rewind, causing the second fixing block to clamp the pipeline. This allows it to adapt to and fix ECMO pipelines of different diameters and sizes, achieving the effect of quickly fixing the pipeline. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1: A fixation device for extracorporeal membrane oxygenation (ECMO) tubing, such as... Figure 1 , Figure 2 and Figure 3As shown, it includes a fixing band 1, a first fixing block 4, a first connecting block 5, a second connecting block 6, a second fixing block 7, a coiled spring 8, and a third connecting block 91. The first fixing block 4 is installed in the middle of the fixing band 1. A large number of ventilation holes 11 are evenly spaced on the fixing band 1, which allows the skin under the fixing band 1 to exchange with the outside air better, reducing dampness and stuffiness, thereby improving the patient's comfort. The first connecting blocks 5 are installed on both sides of the first fixing block 4. The coiled spring 8 is fitted at the front end of the first connecting block 5. The second connecting block 6 is installed at the front end of the first connecting block 5. The second connecting block 6 is connected to and wraps around the coiled spring 8. The second fixing block 7 is connected to the second connecting block 6. The third connecting block 91 is connected to the bottom of the second connecting block 6. By pressing the third connecting block 91, the second fixing block 7 can be easily pulled open. The second fixing block 7 is an arc-shaped clamping block. Under the action of the coiled spring 8, the second fixing block 7 can clamp and fix the tube in the middle.

[0020] When it is necessary to fix the pipeline, pull the second fixing blocks 7 on both sides outward, so that the second connecting block 6 rotates and drives the spiral spring 8 to unfold. Then, place the pipeline on the first fixing block 4, release the second fixing blocks 7 on both sides, and the second fixing blocks 7 will reset under the drive of the spiral spring 8's winding force, thereby clamping the pipeline and ensuring that the pipeline can be firmly fixed in the device, avoiding potential risks caused by pipeline movement or detachment, and can adapt to ECMO pipelines of different diameters and sizes.

[0021] Example 2: Based on Example 1, such as Figure 4 As shown, it also includes a first Velcro 2 and a second Velcro 3. The first Velcro 2 is attached to the upper left side of the fixing strap 1, and the second Velcro 3 is attached to the lower right side. The first Velcro 2 and the second Velcro 3 are movably attached and each has a large number of ventilation holes 11, so that users can easily adjust their tightness as needed. It is suitable for users of different body types and needs, ensuring that the fixing strap 1 can fit the body tightly without being too tight and causing discomfort. The ventilation holes 11 help keep the skin dry, which helps prevent the growth of bacteria and fungi and reduces the possibility of skin infection.

[0022] like Figure 2 and Figure 4As shown, it also includes a first rubber pad 9 and a second rubber pad 10. A first rubber pad 9 is attached to the first fixing block 4 and the inner side of the two second fixing blocks 7. The rubber material has the characteristics of being soft and wear-resistant, which can protect the contact surface from scratches, wear or damage, and prevent damage to the pipeline. The bottom of the fixing band 1 is attached to the second rubber pad 10, and the second rubber pad 10 has a large number of ventilation holes 11, which allows the skin in contact with the second rubber pad 10 to exchange with the outside air better, keeping the skin dry. The soft material of the rubber pad can reduce the friction between the skin and the fixing band 1, reducing the risk of skin damage.

[0023] When it is necessary to fix the tubing to a certain part of the patient's body, a suitable fixation position should be selected on the patient's body according to the specific situation of the patient and the location requirements of the tubing. The fixation strap 1 should be wrapped around the selected position. After the fixation strap 1 is wrapped around the body, the two ends should be tightened to make the fixation strap 1 firmly fixed in the selected position. Then, the first Velcro 2 and the second Velcro 3 should be attached together. After attaching the Velcro, check the tightness of the fixation strap 1. If the fixation strap 1 is too loose, it may cause instability of the tubing; if it is too tight, it may cause discomfort to the patient. Therefore, appropriate adjustments need to be made according to the actual situation and needs of the patient.

[0024] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
