Description

Technical Field

[0001] This utility model relates to the field of pipeline fixing technology, and in particular to an ECMO pipeline fixing and decompression device. Background Technology

[0002] ECMO (Extracorporeal Membrane Oxygenation) is a treatment technology used for patients with severe cardiopulmonary failure. It provides continuous respiratory and circulatory support through extracorporeal circulation to sustain the patient's life. ECMO mainly consists of intravascular cannulas, connecting tubing, a power pump (artificial heart), an oxygenator (artificial lung), oxygen supply tubing, and a monitoring system.

[0003] According to the search, Chinese patent number CN222585172U discloses an ECMO tubing fixing and decompression device, including: a support cover and a cover plate, wherein an upper pipe groove and a lower pipe groove are respectively opened between the support cover and the cover plate, and the upper pipe groove and the lower pipe groove are arranged opposite to each other to form a circular hole.

[0004] The aforementioned publicly available documents describe how the ECMO tubing can be fixed by placing it in a circular hole and using a support cover and a cover plate. However, in actual operation, there is a problem. When fixing the ECMO tubing, it is necessary to first place the ECMO tubing in the lower pipe groove on the support cover, and then put the cover plate on so that the upper part of the ECMO tubing is placed in the upper pipe groove. Before putting the cover plate on, only half of the ECMO tubing is in the lower pipe groove. At this time, the ECMO tubing is not effectively restrained, so the ECMO tubing may deviate from the lower pipe groove. As a result, after putting the cover plate on, the ECMO tubing cannot be completely placed in the circular hole and fixed, unless the ECMO tubing is pressed down by hand beforehand to prevent it from moving before putting the cover plate on. This method is very inconvenient to use.

[0005] To address the aforementioned issues, this application proposes a fixed pressure relief device for ECMO tubing. Utility Model Content

[0006] This invention provides an ECMO pipeline fixing and pressure reduction device to solve the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, this utility model provides an ECMO tubing fixing and decompression device, including a base, a cover plate connected to the top of the base, multiple tube grooves opened on the top of the base, multiple spring plates fixedly connected to the inner side wall of the tube grooves, an arc-shaped rubber pad embedded in the bottom wall of the tube grooves, multiple rubber pressure strips fixedly connected to the bottom of the cover plate, the rubber pressure strips being located inside the tube grooves and directly above the arc-shaped rubber pads, and straps fixedly connected to both sides of the base.

[0008] Preferably, the arc-shaped rubber pad is located below the spring sheet, and the rubber pressure strip is located between two adjacent spring sheets.

[0009] Preferably, the bottom of the rubber strip is machined into an arc-shaped groove.

[0010] Preferably, the base has two slots on both sides, and the cover plate has two buckles fixedly connected to both sides. The buckles are located inside the slots, and the base and the cover plate are fixedly connected by the buckles and slots.

[0011] Preferably, a soft pad is fixedly connected to the bottom of the base.

[0012] Compared with related technologies, the ECMO tubing fixing and decompression device provided by this utility model has the following beneficial effects:

[0013] By creating a groove in the base and installing spring plates on the inner wall of the groove, the ECMO tubing embedded in the groove can be pre-positioned, preventing the ECMO tubing from detaching from the groove before the cover is closed. It also eliminates the need for manual positioning. After closing the cover, the rubber strip under the cover will press against the ECMO tubing to fix it in the groove. The operation is simple and very convenient. Attached Figure Description

[0019] Implementation examples, by Figure 1-4The present invention includes a base 1, a cover plate 2 connected above the base 1, multiple tube grooves 5 opened on the top of the base 1, multiple spring plates 6 fixedly connected to the inner side wall of the tube grooves 5, an arc-shaped rubber pad 7 embedded in the bottom wall of the tube grooves 5, multiple rubber pressure strips 8 fixedly connected to the bottom of the cover plate 2, the rubber pressure strips 8 being located inside the tube grooves 5 and directly above the arc-shaped rubber pads 7, and straps 3 fixedly connected to both sides of the base 1, both straps 3 being made of elastic fabric and being fixed to each other by Velcro, so as to bind and fix the base 1 to the patient's limb and flexibly adapt to the size of the patient's limb.

[0020] The arc-shaped rubber pad 7 is located below the spring sheet 6, and the rubber strip 8 is located between two adjacent spring sheets 6. The bottom of the rubber strip 8 is machined into an arc-shaped groove. The arc-shaped rubber pad 7 is located below the spring sheet 6 to avoid interference between the two. The inner surface of the arc-shaped rubber pad 7 fits perfectly against the lower surface of the ECMO tubing, and the arc-shaped groove at the bottom of the rubber strip 8 fits perfectly against the upper surface of the ECMO tubing. This allows the ECMO tubing to be sandwiched between the arc-shaped rubber pad 7 and the rubber strip 8 inside the tubing groove 5. The high friction characteristics of the two enhance the fixation effect of the ECMO tubing. Furthermore, due to the shape and material characteristics of the arc-shaped rubber pad 7 and the rubber strip 8, the ECMO tubing is fixed without being squeezed or deformed.

[0021] The base 1 has two slots 10 on both sides, and the cover plate 2 has two buckles 9 fixedly connected to both sides. The buckles 9 are located inside the slots 10, and the base 1 and the cover plate 2 are fixed together by the buckles 9 and the slots 10. The base 1 and the cover plate 2 can be quickly and easily fixed together by the buckles 9 and the slots 10. The buckles 9 have anti-slip texture on the outside to facilitate the installation and removal of the cover plate 2.

[0022] A soft pad 4 is fixedly connected to the bottom of the base 1. The soft pad 4 can be made of breathable sponge and is located between the base 1 and the patient's limb skin. This can prevent the base 1 from pressing on the patient's limb and causing pressure sores, improve comfort, and has a certain degree of breathability.

[0023] Working principle:

[0024] When fixing the ECMO tubing, the ECMO tubing can be embedded inside the tubing groove 5. During the embedding of the ECMO tubing, the spring plate 6 will deform due to the compression of the ECMO tubing. After the ECMO tubing is fully inserted into the tubing groove 5, the spring plate 6 will return to its original shape as it is no longer compressed. At this time, the spring plate 6 is located diagonally above the ECMO tubing and limits its position, so that the ECMO tubing will not easily detach from the tubing groove 5. Then, the cover plate 2 is placed on the base 1 and fixed by the cooperation of the buckle 9 and the slot 10. When the cover plate 2 is fixedly placed on the base 1, the rubber strip 8 at the bottom of the cover plate 2 will press against the outer surface of the ECMO tubing. At this time, the ECMO tubing is fixed inside the tubing groove 5. At the same time, the arc-shaped rubber pad 7 and the rubber strip 8 have a large friction with the contact surface of the ECMO tubing outer wall, further preventing the ECMO tubing from being pulled. Then, the base 1 can be tied to the patient's limb with the strap 3.
