Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a magnetic drape for extracorporeal membrane oxygenation (ECMO) catheter placement. Background Technology

[0002] Extracorporeal membrane oxygenation (ECMO) is a respiratory and circulatory support technology. Its principle involves draining the patient's venous blood through a centrifugal pump to an artificial lung (oxygenator), where it is oxygenated into arterial blood before being returned to the body to replace the heart and lungs. As one of the extracorporeal life support technologies, its application in intensive care units (ICUs) and emergency departments is increasing year by year. The ECMO drape primarily ensures maximum sterility during surgery, preventing catheter-related bloodstream infections.

[0003] Currently, standard surgical drapes are suitable for operating room beds but have a small coverage area, making them unsuitable for monitoring beds, let alone covering infusion equipment such as infusion pumps around the monitoring bed. Furthermore, once a closed-loop circulation system is established after surgery, the drape cannot be completely removed by threading it through the system. After catheter placement, timely confirmation of the catheter's position requires ultrasound examination under aseptic conditions, which standard surgical drapes cannot provide. If central venous puncture on one side fails and puncture on the other side is necessary, the drape must be moved, violating aseptic principles. In addition, sterile drapes are not stably fixed to the puncture site, allowing for free movement. This means the disinfected skin at the puncture site is not properly protected and is susceptible to contamination due to movement of the drape caused by patient repositioning. Moreover, clinicians commonly fail to disinfect the skin area adequately during procedures and often forget to disinfect the area afterward. Utility Model Content

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0028] The magnetic drape 100 for extracorporeal membrane oxygenation (ECMO) tube placement according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the magnetic drape 100 for extracorporeal membrane oxygenation (ECMO) tube placement according to an embodiment of the present invention includes: a first protective layer 10 and a second protective layer 20.

[0030] Specifically, the first protective layer 10 has an adhesive layer 11 along its first side of thickness, and a first magnetic element 12 along its second side of thickness. The second protective layer 20 is the main body of the drape. The area of ​​the second protective layer 20 is larger than that of the first protective layer 10. The second protective layer 20 has a second magnetic element 21, and there is a magnetic attraction between the second magnetic element 21 and the first magnetic element 12.

[0031] In other words, the magnetic suction drape 100 for extracorporeal membrane oxygenation (ECMO) catheter placement according to this embodiment of the present invention mainly consists of a first protective layer 10 and a second protective layer 20. The first protective layer 10 has an adhesive layer on its first side and a first magnetic suction element 12 on its second side. In use, the first protective layer 10 can be first attached to the skin via the adhesive layer, and then the second protective layer 20 can be placed over it. Because the second protective layer 20 has a larger area, it can cover the entire first protective layer 10 and extend beyond its edge, thus providing protection for a wider area. Furthermore, the larger area of ​​the second protective layer 20 makes it suitable for use with monitoring beds and allows for better coverage of infusion equipment such as infusion pumps around the monitoring bed.

[0032] It should be noted that, since there is a magnetic attraction between the first magnetic member 12 and the second magnetic member 21, when the second protective layer 20 is placed on the second side of the first protective layer 10, the first magnetic member 12 and the second magnetic member 21 are attracted together, thereby fixing the relative position between the first protective layer 10 and the second protective layer 20.

[0033] According to one embodiment of the present invention, the first protective layer 10 is a medical non-woven fabric, which can be modified from existing medical non-woven fabrics to reduce costs.

[0034] In some specific embodiments of this utility model, the second protective layer 20 is provided with a first through hole 13 extending along its own thickness direction. A third magnetic chuck 22 is provided on the outer edge of the first through hole 13. The magnetic chuck drape 100 for extracorporeal membrane oxygenation (ECMO) tube placement also includes a first baffle 23, on which a fourth magnetic chuck is provided. The first baffle 23 is transparent or semi-transparent and detachably covers the first through hole 13. The third magnetic chuck 22 and the fourth magnetic chuck have magnetic attraction. That is, in addition to the second magnetic chuck 21, the second protective layer 20 also has a first through hole 13, and the third magnetic chuck 22 is provided on the outer periphery of the first through hole 13. To prevent mutual interference, the second magnetic chuck 21 and the third magnetic chuck 22 can be staggered. Furthermore, the first baffle 23 can seal the first through hole 13. The first baffle 23 can be connected to the third magnetic component 22 via its own fourth magnetic component, thereby enabling the installation between the first baffle 23 and the second protective layer 20. In other words, the first through hole 13 and the first baffle 23 cooperate to form a transparent observation window, allowing observation of the patient's artificial airway and other conditions. Moreover, in this embodiment, the observation window allows for timely confirmation of the tube's position after insertion, while ensuring sterile conditions.

[0035] According to one embodiment of the present invention, the second protective layer 20 has a long side and a wide side, and the first through hole 13 is located near one of the wide sides of the second protective layer 20. For example, the second protective layer 20 is a long strip, with its long side extending in the front-back direction and its wide side extending in the left-right direction. The first through hole 13 is located near the edge of the wide side at the front end of the second protective layer 20. In this embodiment, by placing the first through hole 13 near the wide side of the second protective layer 20, the characteristic that the height of the human body is usually greater than its width is utilized. This not only saves materials, but also makes it easier to observe through the first through hole 13, taking advantage of the characteristics of the human body.

[0036] In some specific embodiments of this utility model, the second protective layer 20 is provided with a second through hole extending along its own thickness direction. A fifth magnetic suction member 24 is provided on the outer edge of the second through hole. The magnetic suction drape 100 for extracorporeal membrane oxygenation (ECMO) catheter placement further includes a second baffle 25, on which a sixth magnetic suction member 26 is provided. The second baffle 25 detachably covers the second through hole. When the second baffle 25 is open, the second through hole serves as an ultrasound window. The fifth magnetic suction member 24 and the sixth magnetic suction member 26 have a magnetic attraction. For example, the second protective layer 20 is provided with a second through hole, and the second baffle 25 can close or open the second through hole. When the second through hole is closed, the fifth magnetic suction member 24 and the sixth magnetic suction member 26 cooperate with each other. When the second baffle 25 is opened, it is only necessary to overcome the attraction between the fifth magnetic suction member 24 and the sixth magnetic suction member 26 and move the second baffle 25 to realize the function of the second through hole as an ultrasound window. In other words, the ultrasonic window has a magnetic adhesion effect, which can be separated during catheter placement to open the window for ultrasonic positioning.

[0037] According to one embodiment of the present invention, the second through hole is located at the center of the second protective layer 20, which facilitates the simultaneous fulfillment of the two needs of the human body: ultrasound positioning and surrounding protection.

[0038] In some specific embodiments of this utility model, an opening 27 is provided along one edge of the second protective layer 20, extending towards the location of the first protective layer 10. In this embodiment, by providing an opening 27 at the edge of the second protective layer 20, it is not only beneficial to achieve a three-dimensional characteristic for the second protective layer 20, but also to enable the drape to be completely removed through the tube after a closed-loop circulation has been established at the end of the surgery. Furthermore, by providing an opening 27, if central venous puncture on one side is unsuccessful and puncture on the other side is required, there is no need to move the drape.

[0039] Optionally, when there are multiple positions of the first magnetic attractor 12, there can also be multiple positions of the opening 27, and the multiple first magnetic attractors 12 can correspond one-to-one with the multiple openings 27. For example, the second protective layer 20 is an elongated piece, and two spaced-apart second magnetic attractors 21 are provided in each of the width directions of the second protective layer 20, and an opening 27 is provided at the corresponding position of the width.

[0040] According to one embodiment of this utility model, a seventh magnetic attractor and an eighth magnetic attractor are provided on the second protective layer 20. The seventh magnetic attractor is located at one edge of the opening 27, and the eighth magnetic attractor is located at the other edge of the opening 27. The seventh magnetic attractor and the eighth magnetic attractor have a magnetic attraction. In this embodiment, the opening 27 can be opened or closed, and the connection method and position of the two edges of the opening 27 can be controlled by the seventh magnetic attractor and the eighth magnetic attractor.

[0041] According to one embodiment of this utility model, the first magnetic suction member 12 is a rectangular frame or a circular frame, which not only helps to reduce cost and weight, but also makes it easier to avoid locations such as wounds.

[0042] In some specific embodiments of this utility model, the second magnetic member 21 has the same shape as the first magnetic member 12, which helps to reduce costs and weight.

[0043] According to one embodiment of the present invention, the number of the first protective layer 10 and the second magnetic attractor 21 are multiple and correspond one-to-one, which is beneficial to improving the positioning effect of the first protective layer 10 and the second protective layer 20.

[0044] The magnetic drape 100 for extracorporeal membrane oxygenation (ECMO) tube placement according to the present invention will be described in detail below with reference to specific embodiments.

[0045] First, the operator applies the adhesive (adhesive layer 11) of the sterile medical non-woven fabric (first protective layer 10) to the patient's intended puncture site, using this as the disinfection area to prevent problems such as insufficient disinfection area or incomplete disinfection; a sterile magnetic frame (first magnetic component 12) is attached to it.

[0046] Subsequently, after the operator has disinfected the sterile magnetic frame on the sterile medical nonwoven fabric, the sterile medical nonwoven drape (second protective layer 20) can be aseptically laid on the patient to establish a sterile area; wherein, the sterile medical magnetic frame (second magnetic component 21) on the sterile medical nonwoven drape is aligned with the sterile magnetic frame (first magnetic component 12) attached to the patient's skin; the two are magnetically attracted to create an adhesive force, thereby thoroughly protecting the disinfected skin from contamination by gaps or patient movement.

[0047] In summary, the magnetic drape 100 for extracorporeal membrane oxygenation (ECMO) catheter placement according to the present invention combines a first protective layer 10 and a second protective layer 20. The second protective layer 20 is not easily moved, which can effectively improve the aseptic protection effect.

[0048] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
