Description

Technical Field

[0001] The utility model relates to the technical field of structural design of medical devices for extracorporeal membrane oxygenation pipeline fixation, and in particular to an ECMO pipeline fixation decompression device. Background Art

[0002] Artificial membrane lung, also known as ECMO (extracorporeal membrane oxygenation), is an artificial heart-lung machine, mainly used for patients with severe heart and lung failure. It provides patients with continuous extracorporeal oxygenation and circulatory support, reduces the patient's cardiopulmonary burden, and buys medical staff more time for treatment.

[0003] ECMO pipeline fixed decompression device is mostly used in clinical practice or during ECMO patient transfer. The ECMO pipeline fixed decompression method is: fix the puncture site with percutaneous sutures, cover with sterile dressings, and use Ulysse (elastic adhesive bandage) to apply pressure in a cross method, stick it to the thigh, keep the pipeline straight, close to the operated limb, and stick it to the non-joint part of the operated limb with Ulysse in turn. When ECMO mechanical circulatory assistance is used clinically, intravascular cannulation and connecting tubes are required for fixation.

[0004] At present, hospitals usually need to cut medical tape multiple times to fix ECMO tubes, and then use medical tape to fix the ECMO tubes to the patient's skin, which may cause skin allergies or sweat to separate from the medical tape, and the ECMO tubes may be easily squeezed and deformed.

[0005] It can be seen that the prior art does not have a medical device specifically used to fix ECMO tubes. The ECMO tubes are not adequately protected, and the ECMO tubes are easily squeezed and deformed, causing serious injuries to patients and even affecting their life safety. Utility Model Content

[0006] In view of this, the main purpose of the utility model is to provide an ECMO pipeline fixing and decompression device which can improve the fixing strength of the ECMO pipeline, guide the extension direction of the ECMO pipeline, ensure the conduction between the ECMO system and the patient, and improve the treatment effect.

[0042] The ECMO pipeline fixing pressure reducing device of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0047] like Figure 1-Figure 3 As shown, the ECMO pipeline fixed decompression device is characterized in that it includes: a support cover 1 connected to the patient's leg support and a cover plate 2 covering the upper side of the support cover 1 and leaving a space for the ECMO pipeline 20 to pass through. In order to meet the decompression effect on the ECMO pipeline 20, avoid the external objects from squeezing and deforming the ECMO pipeline, and affect the flow of blood inside the ECMO pipeline 20, an upper pipeline groove 3 and a lower pipeline groove 4 are respectively opened between the support cover 1 and the cover plate 2, and the upper pipeline groove 3 and the lower pipeline groove 4 are relatively arranged to form a circular hole 5. The diameter of the circular hole 5 is the same as the outer diameter of the ECMO pipeline 20, which can meet the smooth passage of the ECMO pipeline 20, and support the ECMO pipeline 20 through the area to avoid squeezing of the ECMO pipeline 20 by external objects. Thereby ensuring that the ECMO pipeline 20 conducts the patient and the ECMO system 10.

[0048] In order to ensure that the ECMO pipeline 20 is bent when it extends out of the circular hole 5, a guide tube 6 is fixedly connected to the end of the lower pipeline groove 4. The guide tube 6 supports the ECMO pipeline 20 and guides it to the elongation direction to prevent the ECMO pipeline 20 from bending.

[0049] In order to facilitate the fixed connection of the support cover 1 to the patient's leg, the support cover 1 is prevented from shaking, which affects the end of the ECMO tube 20 extending into the patient's body from being pulled out, which not only affects the use effect of the ECMO tube 20, but also easily causes secondary damage to the patient. The two sides of the support cover 1 are respectively fixedly connected with the binding belt 7. The binding belt 7 is wound around the patient's leg and fixed to the patient's leg by Velcro, so as to ensure that the decompression device fixes the ECMO tube 20.

[0050] In order to ensure the ventilation effect of the contact position between the support cover 1 and the patient and improve the protection of the patient's legs, the bottom of the support cover 1 is fixedly connected to the bottom cover 8, and a ventilation groove 81 is provided at the bottom of the bottom cover 8. The bottom cover 8 is preferably made of cotton and polyester blended to improve skin affinity.

[0051] In order to improve the fixing effect on the ECMO pipeline 20, a certain pressing force is required on the ECMO pipeline 20. However, if the hardness of the support cover 1 is relatively large, it is easy to cause excessive pressure and deformation of the ECMO pipeline 20. Therefore, the preferred support cover 1 includes: a support shell 11 and a support seat 12. The support seat 12 is fixedly connected to the inner part of the upper cavity of the support shell 11, and the lower pipeline groove 4 is opened on the upper surface of the support seat 12. By selecting different materials for the support seat 12, the support seat 12 can be deformed during the compression and fixing process of the ECMO pipeline 20, and the ECMO pipeline 20 will not be squeezed and deformed, thereby ensuring the fluidity of the ECMO pipeline 20. In order to ensure the fixing strength of the support seat 12 and avoid interference with the support shell 11, the cross-section of the support shell 11 is a U-shaped groove body, and the upper ends of the support walls 13 on both sides of the support shell 11 are flush with the upper surface of the support seat 12.

[0052] Similarly, the same principle as the support cover 1 can not only fix the ECMO pipeline 20, but also avoid squeezing and deforming the ECMO pipeline 20. The cover plate 2 includes: a cover shell 21 and a clamping plate 22. The cavity on the lower side of the cover shell 21 is fixedly connected to the clamping plate 22. The clamping plate 22 opens the upper pipeline groove 3. The cross section of the cover shell 21 is an inverted U-shaped groove. The lower ends of the fixing plates 23 on both sides of the cover shell 21 are flush with the lower bottom surface of the clamping plate 22. The interference of the cover shell 21 is also avoided, and the ECMO pipeline 20 can be fixed by the clamping plate 22.

[0053] In order to ensure the support between the cover shell 21 and the support shell 11, the support seat 12 and the pressing plate 22 are prevented from being squeezed by the outside world, which affects the safety of the ECMO tube 20. The fixing plates 23 on both sides of the cover shell 21 and the upper ends of the supporting walls 13 on both sides of the support shell 11 are aligned and supported. Through the support of the fixing plates 23 and the support arms 13, the ECMO tube 20 can be surrounded in a sealed space to avoid squeezing of the ECMO tube 20.

[0054] In order to connect the support walls 13 , two symmetrical support walls 13 are fixedly connected via a connecting plate 14 .

[0055] Of course, in order to further avoid squeezing the ECMO tube 20, the support seat 12 and the pressing plate 22 are both made of compressible elastic materials, preferably sponge materials.

[0056] In order to ensure the compactness of the entire structure and avoid separation of the cover shell 21 and the support shell 11, the cover shell 21 and the support shell 11 are hinged on opposite sides. In order to improve the tightness of the connection between the cover shell 21 and the support shell 11, a latch hole 24 is provided on the edge of the other side of the cover shell 21, and a latch groove 15 is provided on the upper surface of the edge of the other side of the support shell 11. A latch 9 is provided through the latch hole 24, and the latch 9 is inserted into the latch groove 15 for connection.

[0057] In order to improve the connection strength of the binding belt 7 and provide a buffering effect on the patient's legs during the binding process, the upper end of the binding belt 7 is fixedly connected to the lower bottom edge of the support shell 11. The bottom cover 8 is constrained to the binding belt 7 to act on the thigh surface.

[0058] In order to improve the guiding effect of the guide tube 6, especially when bending, the ECMO pipeline 20 can be bent and guided, and it is in a bent state for a long time to ensure the circulation effect of the ECMO pipeline 20 in a complete state. The tube wall of the guide tube 6 is a bendable plastic material, and a plastic aluminum alloy wire is embedded in the length direction of the tube wall of the guide tube 6. The plastic aluminum alloy wire is used to improve the fixed forming after bending, and the bendable plastic material is used for buffering to ensure the bending and guiding of the ECMO pipeline 20.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
