Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a fixation device for ECMO tubing. Background Technology

[0002] Extracorporeal membrane oxygenation (ECMO) is an advanced life support technology primarily used to provide temporary circulatory and respiratory support for patients with severe cardiopulmonary failure. Clinically, ECMO is widely used to treat acute respiratory distress syndrome, cardiac arrest, myocardial infarction, pneumonia, pulmonary embolism, and myocarditis, providing temporary replacement support for the patient's cardiopulmonary system and buying time for the treatment of the primary disease and the recovery of cardiopulmonary function. Figure 4 The system drains the patient's venous blood to the outside through the drainage tube 01, oxygenates it and removes carbon dioxide through the membrane lung, and then pumps the oxygenated blood back into the patient's body through the supply tube 02, thereby replacing the patient's cardiopulmonary function.

[0003] In clinical practice, when patients undergo extracorporeal membrane oxygenation (ECMO), medical staff typically use a bandage to secure the drainage tube 01 to the patient's head to prevent displacement or dislodgement during blood flow. However, this method has a problem: when the patient changes position or moves their head, the bandage may not be securely fastened, easily leading to displacement or dislodgement of the drainage tube 01, which can interrupt oxygenation and endanger the patient's life. Furthermore, the connection between the drainage tube 01 and the bandage is prone to bending, increasing resistance to blood flow and potentially causing catheter blockage in severe cases, endangering the patient's life.

[0004] Therefore, designing a fixation device for ECMO tubing that can ensure the drainage tube remains in place when the patient's position changes or the head moves is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects in the prior art, which cause the drainage tube to easily shift or fall off during blood flow due to the loose fixation of the strap, and thus provide a fixation device for ECMO tubing that can ensure that the drainage tube remains in the original position when the patient's body position changes or the head moves.

[0006] Therefore, this utility model provides a fixation device for ECMO tubing, comprising: a main body having a receiving cavity with a bottom opening, suitable for adjusting the size to fit on the head of patients with different head circumferences; a first fixation structure fixedly disposed at the bottom of the main body, capable of adjusting the tightness to fix the main body to the patient's head; a fixation member fixedly disposed on one side outer wall of the main body, extending through both ends along the axis and having an opening on one side; an anti-folding sleeve, hollow with openings at both ends, the bottom end fixedly disposed at the top of the fixation member, and having a side opening opposite to the side opening of the fixation member; and a drainage tube adapted to be inserted into the fixation member and the anti-folding sleeve from the side opening and the side opening, and being limited and fixed.

[0007] As a preferred embodiment, the anti-folding sleeve has several annular openings evenly spaced around its circumference, with one end of each annular opening connected to the side opening and the other end closed.

[0008] As a preferred embodiment, the opening directions of two adjacent annular openings are arranged in opposite directions.

[0009] As a preferred embodiment, the anti-bend sleeve extends downward from the end away from the fixing member, with its outer diameter gradually increasing, while the inner diameter of the anti-bend sleeve is the same at the top and bottom.

[0010] As a preferred embodiment, it also includes an anti-slip part, which is integrally formed at the side opening at the top of the anti-folding sleeve and extends outward by a certain distance.

[0011] As a preferred embodiment, the first fixing structure includes: a first fixing strap, one end of which is fixedly disposed at the bottom of the main body, and the other end of which is a free end; a second fixing strap, which is disposed opposite to the first fixing strap on the bottom of the other side of the main body, and the other end of which is a free end; the first fixing strap and the second fixing strap can be adhesively connected together.

[0012] As a preferred embodiment, the outer side of the first fixing strap is provided with a loop fastener; the inner side of the second fixing strap is provided with a hook fastener, the loop fastener being able to adhere to the hook fastener, thereby adjusting the tightness to fix the main body to the patient's head.

[0013] As a preferred embodiment, the main body includes a hood and a brim integrally formed at the bottom of the hood.

[0014] As a preferred embodiment, the hood has several heat dissipation holes that connect to the receiving cavity.

[0015] The technical solution provided by this utility model has the following advantages:

[0016] This utility model discloses a fixation device for ECMO tubing, comprising a main body, a first fixation structure, a fixation member, and an anti-folding sleeve. The main body has a receiving cavity with a bottom opening, suitable for adjusting the size to fit patients with different head circumferences. The first fixation structure is fixedly disposed at the bottom of the main body and can adjust the tightness to fix the main body to the patient's head. The fixation member is fixedly disposed on one side of the outer wall of the main body, extending through both ends along the axis and having an opening on one side. The anti-folding sleeve is hollow and has openings at both ends, with its bottom end fixedly disposed at the top of the fixation member, and has a side opening opposite to the side opening of the fixation member. A drainage tube is suitable for being inserted into the fixation member and the anti-folding sleeve from the side opening and the side opening, and is limited and fixed.

[0017] For patients undergoing extracorporeal membrane oxygenation (ECMO), doctors will make punctures in the patient's neck and groin, then establish an internal jugular vein-femoral vein catheter using cannulation techniques, and connect it sequentially to the extracorporeal circulation tubing. A centrifugal pump will then be activated to drive blood flow. Once the system is in a stable operating state, the ECMO tubing needs to be securely fixed. To fix the tubing, the drainage tube is first placed naturally along the body surface from the patient's neck towards the head. Next, the main component is placed on the patient's head. Then, depending on the patient's condition, the first fixation structure is adjusted to a suitable tightness and fixed. Finally, the drainage tube is inserted into the fixation component and anti-bend sleeve through the opening and side opening to achieve limited fixation of the drainage tube. This utility model provides a fixation device for ECMO tubing that can securely fix the drainage tube to the patient's head, preventing displacement or dislodgement. Furthermore, the anti-bend sleeve also has an anti-bending function, effectively preventing the drainage tube from bending and ensuring the smooth progress of treatment. Attached Figure Description

[0027] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0028] This embodiment provides a fixing device for ECMO tubing, such as... Figure 1-3 As shown, it includes: a main body 5, a first fixing structure 3, a fixing member 41, and an anti-folding sleeve 42; wherein the main body 5 has a receiving cavity 11 with a bottom opening, suitable for adjusting the size to be worn on the head of patients with different head circumferences; the first fixing structure 3 is fixedly disposed at the bottom of the main body 5, and can adjust the tightness to fix the main body 5 to the patient's head; the fixing member 41 is fixedly disposed on one side of the outer wall of the main body 5, extending through both ends along the axis and having an opening on one side; the anti-folding sleeve 42 is hollow and has openings at both ends, with its bottom end fixedly disposed at the top of the fixing member 41, and a side opening 421 is provided opposite to the side opening of the fixing member 41; a drainage tube is adapted to be inserted into the fixing member 41 and the anti-folding sleeve 42 from the side opening and the side opening 421, and is limited and fixed.

[0029] For patients undergoing extracorporeal membrane oxygenation (ECMO), doctors will make punctures in the patient's neck and groin, then establish an internal jugular vein-femoral vein catheter using cannulation techniques, and connect it sequentially to the extracorporeal circulation tubing. A centrifugal pump will then be activated to drive blood flow. Once the system is in a stable operating state, the ECMO tubing needs to be securely fixed. To fix the tubing, the drainage tube 01 is first placed naturally along the body surface from the patient's neck towards the head. Next, the main body 5 is placed on the patient's head. Then, according to the patient's condition, the first fixing structure 3 is adjusted to a suitable tightness and fixed. Afterwards, the drainage tube 01 is inserted into the fixing member 41 and the anti-bend sleeve 42 through the opening and side opening 421, thus achieving the limiting and fixing of the drainage tube 01. This embodiment of the ECMO tubing fixing device can securely fix the drainage tube 01 to the patient's head, preventing displacement or dislodgement. In addition, the anti-bend sleeve 42 also has an anti-bending function, effectively preventing the drainage tube 01 from bending and ensuring the smooth progress of treatment.

[0030] The anti-bend sleeve 42 has several annular openings 422 evenly distributed around its circumference. One end of each annular opening 422 is connected to the side opening 421, and the other end is closed. The evenly distributed annular openings 422 enable the anti-bend sleeve 42 to deform. When the drainage tube is inserted, the anti-bend sleeve 42 can conform to the deformation of the drainage tube, thereby preventing the drainage tube 01 from bending and ensuring smooth blood flow.

[0031] The opening directions of two adjacent annular openings 422 are opposite.

[0032] The anti-bend sleeve 42 extends downwards from the end furthest from the fixing member 41, with its outer diameter gradually increasing. The inner diameter of the anti-bend sleeve 42 is the same at both ends. The anti-bend sleeve 42 has a larger wall thickness at the end fixed to the fixing member 41, resulting in higher structural strength and ensuring connection stability. The anti-bend sleeve 42 has a smaller wall thickness at the end furthest from the fixing member 41, resulting in higher flexibility and allowing it to adapt to the bending of the drainage tube 01 to a certain extent, thereby preventing bending at the connection.

[0033] It also includes an anti-detachment part 43, which is integrally formed at the side opening 421 at the top of the anti-folding sleeve 42 and extends outward by a certain distance. In use, the anti-detachment part 43 should be pried open first, and then the drainage tube should be pressed into the anti-folding sleeve 42. The anti-detachment part 43 prevents the drainage tube from slipping out of the anti-folding sleeve 42, improving stability.

[0034] The first fixing structure 3 includes: a first fixing strap 31 and a second fixing strap 32; wherein one end of the first fixing strap 31 is fixedly disposed at the bottom of the main body 5, and the other end is a free end; the second fixing strap 32 is disposed opposite to the first fixing strap 31 at the bottom of the other side of the main body 5, and the other end is a free end; the first fixing strap 31 and the second fixing strap 32 can be bonded together.

[0035] The first fixing strap 31 has a loop fastener 311 on its outer side; the second fixing strap 32 has a hook fastener 321 on its inner side. The loop fastener 311 can be bonded to the hook fastener 321, thereby adjusting the tightness to fix the main body 5 to the patient's head. In use, one hand presses the first fixing strap 31 against the patient's chin with the loop fastener 311 facing outward, while the other hand presses the second fixing strap 32 against the first fixing strap 31, so that the loop fastener 311 and the hook fastener 321 are attached and fixed. The tightness can then be adjusted to a suitable degree according to the patient's head circumference.

[0036] The main body 5 includes a hood 1 and a brim 2 integrally formed at the bottom of the hood 1.

[0037] The hood 1 has several heat dissipation holes 10 that connect to the receiving cavity 11. The heat dissipation holes 10 can effectively relieve the stuffiness of the patient's head and improve the patient's comfort.

[0038] The method of using the fixing device for ECMO tubing in this embodiment is as follows:

[0039] First, put the hood 1 on the patient's head and ensure that the brim 2 is fixed to the patient's forehead. Then, press the first fixing strap 31 on the patient's chin with one hand and make the hook and loop fastener 311 face outward. Press the second fixing strap 32 on the first fixing strap 31 with the other hand so that the hook and loop fastener 311 and the hook and loop fastener 321 fit together and are fixed. Then, adjust the tightness according to the patient's head circumference. Then, open the anti-slip part 43 and insert the drainage tube 01 into the fixing part 41 and the anti-folding sleeve 42 from the opening and the side opening 421 to achieve the limiting and fixing of the drainage tube.

[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 can make other variations or modifications 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 innovative technical solution.
