Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to an EIT electrode band fixing device. Background Technology
[0002] Electrical impedance tomography (EIT), an emerging medical imaging technology, is based on the differences in resistance / conductivity of different tissues under physiological and pathological conditions. Through electrodes on electrode strips, it performs safe current / voltage excitation and response measurements to reconstruct an image of the body's electrical impedance distribution. This allows for real-time monitoring of changes in lung ventilation, which is of great significance for guiding ventilator parameter settings and evaluating pulmonary function rehabilitation. The EIT electrode strip is a crucial component of the EIT system, containing multiple electrodes. The position of the electrode strip significantly affects the quality and accuracy of EIT imaging. However, EIT electrode strips often suffer from problems such as insecure fixation (patient turning, coughing, etc., can cause electrode strip movement or poor contact between the electrode strip and the patient) and inaccurate positioning during repeated measurements (measurements at different time points cannot effectively ensure the same location), leading to low EIT imaging quality and accuracy. Therefore, there is an urgent need to research an electrode strip fixation device that can reliably fix and accurately position the EIT electrode strip. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide an EIT electrode strip fixing device to solve the technical problems of existing electrode strips being unreliable and unable to be accurately positioned.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an EIT electrode strip fixing device, comprising:
[0005] The fixing sleeve is hollow inside, and one end of the fixing sleeve has an opening for installing the electrode strip inside the fixing sleeve;
[0006] A pair of shoulder straps, one end of each pair of shoulder straps being respectively disposed on the fixing sleeve, and the other end of each pair of shoulder straps being provided with a first fixing piece that adheres to human skin;
[0007] Multiple fixing straps are respectively disposed on both sides of the fixing sleeve to restrict the movement of the fixing sleeve;
[0008] Each pair of shoulder straps is provided with a scale, and each pair of shoulder straps is provided with a plurality of fixing holes spaced apart along its length. The fixing sleeve is provided with a fixing boss that mates with the fixing holes.
[0009] Furthermore, the number of fixing straps is four, with two fixing straps spaced apart on one side of the fixing sleeve and the remaining two fixing straps spaced apart on the other side of the fixing sleeve.
[0010] Furthermore, each of the aforementioned fixing straps is arranged in a triangular shape.
[0011] Furthermore, each of the aforementioned fixing straps is provided with a second fixing piece that adheres to human skin.
[0012] Furthermore, each of the fixing straps is glued or sewn onto the fixing sleeve.
[0013] Furthermore, the fixing sleeve is also provided with a connecting strap, one end of which is connected to a pair of shoulder straps via a connector, and the other end of which is fixed to the fixing sleeve via a fastener.
[0014] Furthermore, the fixed sleeve is provided with an adjusting element for adjusting its tension.
[0015] Furthermore, the fixing sleeve is also provided with a locking buckle.
[0016] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model uses a fixing sleeve with an opening at one end to allow the electrode strip to be installed inside the fixing sleeve; by providing a pair of shoulder straps, they can form an integral structure with the fixing sleeve. When the fixing sleeve containing the electrode strip is fixed to the patient's chest, the first fixing piece attached to the pair of shoulder straps forms a fixing point, thereby fixing the fixing sleeve; by providing multiple fixing straps, each fixed on both sides of the fixing sleeve, multiple fixing points can be formed through the multiple fixing straps, further limiting the movement of the fixing sleeve. This design ensures good fixation of the electrode strap, preventing movement of the electrode strap due to patient turning over or coughing, and ensuring good contact between the electrode strap and the patient. This avoids measurement errors caused by poor contact. By providing scales on each shoulder strap and multiple fixing holes, which can be connected to fixing bosses at different positions, the EIT electrode strap has excellent marking function. This facilitates consistent positioning during repeated measurements, improving the repeatability and reliability of measurement results and enabling precise positioning during measurement.
[0017] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0032] like Figures 1 to 3As shown, this embodiment proposes an EIT electrode strap fixing device, including a fixing sleeve 1, a pair of shoulder straps 2, and multiple fixing straps 3. The fixing sleeve 1 is hollow inside, and one end of the fixing sleeve 1 has an opening through which the electrode strap can be installed inside the fixing sleeve 1. One end of each pair of shoulder straps 2 is respectively disposed on the fixing sleeve 1, and the other end of each pair of shoulder straps 2 is provided with a first fixing piece 4 that is adhered to human skin. In addition, multiple fixing straps 3 are respectively disposed on both sides of the fixing sleeve 1. Furthermore, each pair of shoulder straps 2 is provided with a scale 21, and each pair of shoulder straps 2 is provided with multiple fixing holes 22 spaced apart along its length. The fixing sleeve 1 is provided with fixing bosses 11 that mate with the fixing holes 22. In this way, by setting a fixing sleeve 1 with an opening at one end, the electrode strap can be installed inside the fixing sleeve 1. By setting a pair of shoulder straps 2, they can form an integral structure with the fixing sleeve 1. When the fixing sleeve 1 with the electrode strap is fixed to the patient's chest, the first fixing piece 4 is attached to the pair of shoulder straps 2 to form a fixing point, thereby fixing the fixing sleeve 1. By setting multiple fixing straps 2, each fixing strap 2 is set on both sides of the fixing sleeve 1, multiple fixing points can be formed through multiple fixing straps 3, further limiting the movement of the fixing sleeve 1, so that the fixing sleeve 1 with the electrode strap has good fixation and prevents the patient from turning over or coughing. To prevent the electrode band from shifting due to coughing or other conditions, this device ensures good contact between the electrode band and the patient, thus avoiding measurement errors caused by poor contact. By providing scales 21 on each shoulder strap 2 and multiple fixing holes 22 on the shoulder strap 2, and allowing the fixing holes 22 at different positions to connect with fixing bosses 11, the device can accommodate repeated measurements for patients of different body sizes. This gives the EIT electrode band a good marking function, facilitating consistent positioning during repeated measurements, improving the repeatability and reliability of measurement results, and achieving precise positioning during measurement.
[0033] In this application, the first fixing piece 4 can be a fixing electrode with adhesive properties, or a Velcro, etc. Of course, it can also be other sheet-like structures with adhesive properties, and is not limited to one type here.
[0034] Preferably, there are four fixing straps 3, with two fixing straps 3 spaced apart on one side of the fixing sleeve 1, and the remaining two fixing straps 3 spaced apart on the other side of the fixing sleeve 1. In this way, by setting four fixing straps 3, four fixing points can be formed on each side of the fixing sleeve 1, greatly improving the stability of the fixing sleeve 1 and effectively preventing the electrode strip in the fixing sleeve 1 from shaking during measurement. Of course, in this embodiment, depending on the actual situation and specific needs, the number of fixing straps 3 can also be set to three, five, six, or other multiple numbers; this is not a unique limitation.
[0035] Preferably, the four fixing straps 3 are staggered on both sides of the fixing sleeve 1, thus forming four fixing points at different positions, which enhances the stability of the fixing sleeve 1.
[0036] Preferably, the fixing strap 3 is triangular in shape. By setting it in a triangular shape, it is easier to tighten the fixing strap 3 to enhance its tension, thereby effectively improving the stability of the fixing sleeve 1. Of course, in this embodiment, the fixing strap 3 can also be set in a rhombus shape, an ellipse shape, etc., and is not limited to this specific shape.
[0037] Furthermore, each fixing strap 3 is provided with a second fixing piece 31 that is adhered to human skin. In this way, by providing the second fixing piece 31, a fixing point can be formed by adhering to human skin.
[0038] Preferably, each fixation strap 3 is adhered to the fixation sleeve 1. This adhesive connection allows for easy adjustment of the position of each fixation strap 3 on the fixation sleeve 1 according to actual needs, accommodating different patient body types and enhancing its applicability. Of course, in this application, each fixation strap 3 can also be fixed to the fixation sleeve 1 by sewing, thus forming an integral structure with the fixation strap 3 and enhancing the bonding strength between the two.
[0039] Further, please refer to Figure 2 As shown, the fixing sleeve 1 also has a connecting strap 5. One end of the connecting strap 5 is connected to a pair of shoulder straps via a connector 6, and the other end of the connecting strap 5 is fixed to the fixing sleeve 1 via a fixing member 7. By setting the connecting strap 5, it can conform to the human spine when worn, making it more comfortable to wear.
[0040] Further, please refer to Figure 1 As shown, the fixing sleeve 1 is equipped with an adjusting member 8. By setting the adjusting member 8, the tension of the fixing sleeve 1 can be adjusted in real time according to actual needs to meet the needs of patients of different body types. Preferably, in this application, the adjusting member 8 can be an adjusting buckle similar to a backpack strap, which is inexpensive and easy to operate.
[0041] Further, please refer to Figure 1 and Figure 2 As shown, the fixing sleeve 1 is also provided with a buckle 9. By setting the buckle 9, it is easy to put on the fixing sleeve 1. That is, the fixing sleeve 1 can be opened and closed by means of the buckle 9, which is simple and convenient.
[0042] Preferably, the opening on the fixing sleeve 1 is located at the position of the locking buckle 9. In this way, the electrode strip can be inserted into the fixing sleeve 1 through the opening, and then the fixing strip 3 can be fastened by the locking buckle 9.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
