ECMO (extracorporeal membrane oxygenation) pipe displacement alarm

[0022] In the following, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known processing steps have not been described in detail.

[0023] like figure 1 , figure 2 As shown, the ECMO pipeline displacement alarm includes applicator 1, mounting base 2, moving mechanism 3, monitoring mechanism 4, alarm mechanism 5, sliding pin 6, first spring 7, fastening mechanism 8, and protective film 9. The above-mentioned applicator 1 is pasted with a Velcro sticker with a mounting seat 2. The front and rear ends of the mounting seat 2 are integrally equipped with a moving mechanism 3, and one end of the moving mechanism 3 is fixed with a monitoring mechanism 4. The outer wall of the mechanism 3 is fixed with an alarm mechanism 5, the top of the moving mechanism 3 slides through a slide pin 6, and the outside of the slide pin 6 is provided with a first spring 7, and one end of the first spring 7 is connected to the slide pin 6 is fixedly connected, the other end of the sliding pin 6 is fixedly connected to the moving mechanism 3, the bottom of the sliding pin 6 is fixed with a fastening mechanism 8, and the glue on the bottom of the applicator 1 and the fastening mechanism 8 is protected film 9, the moving mechanism 3 is composed of a mounting groove 10, a slide plate 11, and a second spring 12, and the front and rear ends of the mounting base 2 are integrally provided with mounting grooves 10, and the internal sliding of the mounting groove 10 is provided with Sliding plate 11, the left and right sides of the installation groove 10 are provided with second springs 12, one end of the second spring 12 is fixedly connected to the installation groove 10, and the other end of the second spring 12 is fixedly connected to the sliding plate 11, The monitoring mechanism 4 is composed of a metal sensor 13 and an iron sheet 14. The metal sensor 13 is fixed at the rear end of the slide plate 11, and the iron sheet 14 is fixed at the middle side of the installation groove 10 at the rear end. The iron sheet 14 is in one-to-one correspondence with the metal sensor 13. The alarm mechanism 5 is composed of an alarm 15 and a lithium battery 16. The middle side of the rear end of the slide 11 is fixed with an alarm 15. The back end of the slide plate 11 is closely equipped with a lithium battery 16. The fastening mechanism 8 is composed of a connecting plate 17 and a strong adhesive tape 18. The bottom of the sliding pin 6 is fixed with a connecting plate 17. The connecting plate 17 The bottom Velcro paste is provided with a strong adhesive tape 18 .

[0024] When using the ECMO pipeline displacement alarm, the medical staff first tear off the protective film 9 at the application site 1, and then paste the application 1 with the protective film 9 removed on the intact skin around the patient's treatment site. The staff then places the ECMO pipeline in the mounting seat 2, and then inserts the ECMO pipeline into the patient's treatment site until the depth of the ECMO pipeline inserted into the patient's body meets the needs of the medical staff, and then the medical staff puts the strong adhesive tape 18 The protective film 9 is torn off, and then the sliding pin 6 is pressed by hand, so that the sliding pin 6 drives the connecting plate 17 and the strong tape 18 to move along the direction of the ECMO pipeline. The connection is stable and synchronous, the first spring 7 is deformed, and when the strong tape 18 squeezes the ECMO pipeline to meet the needs of the medical staff, the medical staff releases the sliding pin 6, and the elastic force of the first spring 7 makes the sliding pin 6 The pin 6 drives the connecting plate 17 to reset, that is, to prevent the ECMO pipeline from being crushed, and the medical staff turns on the metal sensor 13 again. When the road is pulled by external force, at this time, the ECMO pipeline drives the strong adhesive tape 18 to link the connecting plate 17 and the sliding pin 6 together with the sliding plate 11 to move along the direction of the installation groove. Synchronously, the second spring 12 deforms. At this time, the metal sensor 13 and the The iron sheet 14 is in a state of misalignment, that is, the metal sensor 13 does not detect the iron sheet 14, and the alarm 15 sends out an alarm sound, which reminds the medical staff that the current ECMO pipeline has been displaced, and the medical staff can immediately check the ECMO pipeline. When the pulling force is eliminated, through the rebound force of the second spring 12, the sliding plate 11 drives the sliding pin 6 to link the connecting plate 17 together with the strong tape 18 and the ECMO pipeline to reset. At the same time, the metal sensor 13 monitors To iron sheet 14, alarm 15 stops working.

[0025] like Figure 4 As shown, the lithium battery 16 in this application is used to provide energy supply to the device, and the lithium battery 16 is connected with the alarm 15 and the metal sensor 13 by wires.
