Description

Technical Field

[0001] This utility model belongs to the field of electrical impedance tomography technology, specifically relating to an information storage device for an electrode strip in electrical impedance tomography. Background Technology

[0002] Electrical impedance tomography (EIT) involves injecting a weak, safe current and measuring the surface voltage using electrodes placed on the human body surface. This creates a tomographic image of the body's electrical impedance characteristics, allowing imaging of changes in the target resistivity distribution to reflect related physiological and pathological information. The electrodes are positioned on the baseband of an electrode strip for contact with the subject's skin, and the baseband is worn on the subject.

[0003] Currently, when using electrical impedance tomography (EIT) technology, different test objects require matching electrode strips of corresponding specifications. Incompatibility between the two will prevent the host from imaging correctly. Furthermore, the electrode strips must be compatible with the corresponding host (model); otherwise, the imaging quality will be affected. However, existing electrode strip specifications vary widely, and mismatched specifications or incompatibility between the electrode strip and the host can easily lead to abnormal images. Utility Model Content

[0004] In view of the above-mentioned defects or improvement needs of the existing technology, this utility model provides an information storage device for electrode strips in electrical impedance tomography. Its purpose is to transmit the data stored therein to the host for electrode strip specification matching identification and electrode strip-host matching identification, thereby avoiding the acquisition of abnormal images.

[0005] To achieve the above objectives, this utility model provides an information storage device for an electrode strip in electrical impedance tomography, the information storage device comprising a housing and a communication component;

[0006] The outer shell is a conductive structure, and one end of the outer shell is used to be mounted on the base strip of the electrode strip;

[0007] The communication component includes conductive posts, a circuit board, a chip, and a probe. The conductive posts are inserted into the other end of the housing and are insulated from the housing. The conductive posts and the housing are used to connect to the host via cables. The circuit board is located inside the housing and is spaced apart from the housing. The conductive posts, the chip, and the probes are all connected to the circuit board, and the conductive posts and probes are located on opposite sides of the circuit board. The chip stores the specification data corresponding to the electrode strip and the host model data matching the electrode strip. One end of the probe contacts the housing.

[0008] Optionally, the information storage device further includes a first insulating tube, which is sleeved outside the conductive post and inserted into the outer casing.

[0009] Optionally, the information storage device further includes a second insulating tube, which is coaxially connected to the first insulating tube. The second insulating tube is located inside the housing, and the circuit board is located inside the second insulating tube.

[0010] Optionally, both the inner peripheral wall of the outer casing and the outer peripheral wall of the conductive post are provided with an insulating varnish layer, and the two insulating varnish layers are bonded together.

[0011] Optionally, the housing includes an upper shell and a base, the upper shell and the base being detachably connected, the base being used to mount on the base of the electrode strip, the conductive post and the circuit board being located inside the upper shell, and one end of the probe contacting the base.

[0012] Optionally, one end of the upper shell is sleeved on one end of the base, and one end of the upper shell is threadedly engaged with one end of the base.

[0013] Optionally, the outer peripheral wall of the upper shell has an annular groove.

[0014] Optionally, the other end of the base is connected to a first connecting plate arranged coaxially, the outer diameter of the first connecting plate being larger than the outer diameter of the base, and the first connecting plate being used to insert into the electrode strip.

[0015] Optionally, one end of the upper shell is connected to a second connecting ring arranged coaxially, the outer diameter of the second connecting ring being larger than the outer diameter of the upper shell, and the second connecting ring being arranged parallel to and spaced apart from the first connecting disc.

[0016] Optionally, both the outer shell and the conductive post are made of metal or carbon.

[0017] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0018] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0019] The information storage device for an electrode strip in electrical impedance tomography provided in this embodiment of the present invention, since one end of the outer shell is used to be installed on the base strip of the electrode strip, the entire device can be reliably fixed on the electrode strip through the outer shell.

[0020] Furthermore, the conductive post is inserted at the other end of the housing. The conductive post, chip, and probe are all connected to the circuit board, with one end of the probe contacting the housing. This creates a positive and a negative conductive path to the chip, which are independent of each other (i.e., insulated from each other). For the positive conductive path, current can flow through the conductive post and circuit board to the chip (positive terminal); for the negative conductive path, current can flow through the housing, probe, and circuit board to the chip (negative terminal). Since the conductive post and housing are used to connect to the host via cables, a closed loop is formed between the chip and the host through the connection of the two cables. The chip can then transmit its stored specification data for the electrode strip and the host model data that matches the electrode strip to the host. The host can then perform matching analysis based on the received data and its internal preset data (including the required electrode strip specifications and the host's own model data), thereby ultimately achieving matching identification of the electrode strip specifications and the matching identification of the electrode strip with the host, avoiding the acquisition of abnormal images (i.e., when both match, the acquired image is a normal image and can be retained; otherwise, it is an abnormal image and should be discarded).

[0021] In other words, the information storage device for electrode strips in electrical impedance tomography provided by this utility model embodiment can transmit the data stored therein to the host for matching identification of electrode strip specifications and matching identification between the electrode strip and the host, thereby avoiding the acquisition of abnormal images.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0033] Example:

[0034] Figure 1 This is a schematic diagram of the structure of an information storage device for an electrode strip in electrical impedance tomography (EIT) provided in an embodiment of this utility model. Figure 2 This is a cross-sectional view of an information storage device for an electrode strip in electrical impedance tomography provided in an embodiment of this utility model. Figure 3 This is an exploded view of an information storage device for an electrode strip in electrical impedance tomography provided by an embodiment of this utility model, combined with... Figures 1-3 As shown, the information storage device includes a housing 1 and a communication component 2.

[0035] The outer casing 1 is a conductive structure, and one end of the outer casing 1 is used to be mounted on the baseband of the electrode strip.

[0036] The communication component 2 includes a conductive post 21, a circuit board 22, a chip 23, and a probe 24. The conductive post 21 is inserted into the other end of the housing 1 and is insulated from the housing 1 (i.e., connected through an insulating structure). The conductive post 21 and the housing 1 are used to connect to the host via cables. The circuit board 22 is located inside the housing 1 and is spaced apart from the housing 1. The conductive post 21, the chip 23, and the probe 24 are all connected to the circuit board 22, and the conductive post 21 and the probe 24 are located on both sides of the circuit board 22. The chip 23 stores the specification data corresponding to the electrode strip and the host model data that matches the electrode strip. One end of the probe 24 is in contact with the housing 1.

[0037] In the present invention, an information storage device for an electrode strip in electrical impedance tomography is provided. Since one end of the outer shell 1 is used to install on the base strip of the electrode strip, the entire device can be reliably fixed on the electrode strip through the outer shell 1.

[0038] Furthermore, the conductive post 21 is inserted into the other end of the housing 1. The conductive post 21, chip 23, and probe 24 are all connected to the circuit board 22. One end of the probe 24 is in contact with the housing 1. At this time, a positive conductive path and a negative conductive path to the chip 23 can be formed, and the two conductive paths are independent of each other (i.e., insulated from each other). For the positive conductive path, the current can be conducted to the chip 23 (positive terminal) through the conductive post 21 and the circuit board 22; for the negative conductive path, the current can pass through the housing 1, probe 24, and circuit board 22 to the chip 23 (negative terminal). Since the conductive post 21 and the outer casing 1 are respectively connected to the host via cables, a closed loop can be formed between the chip 23 and the host through the connection of the two cables. At this time, the chip 23 can transmit the specification data corresponding to the electrode strip and the host model data that matches the electrode strip stored in its own storage to the host. The corresponding host can perform matching analysis with its internal preset data (including the required electrode strip specifications and the host's own model data) based on these received data, thereby ultimately realizing the matching identification of the electrode strip specifications and the matching identification of the electrode strip and the host, avoiding the acquisition of abnormal images (that is, when both match, the acquired image is a normal image and can be retained; otherwise, it is an abnormal image and should be discarded).

[0039] In other words, the information storage device for electrode strips in electrical impedance tomography provided by this utility model embodiment can transmit the data stored therein to the host for matching identification of electrode strip specifications and matching identification between the electrode strip and the host, thereby avoiding the acquisition of abnormal images.

[0040] It should be noted that different electrode strips have different usage counts (image quality degrades when the usage count is reached). For example, there are single-use and multi-use types. Single-use types must be discarded after one use, while multi-use types must also be discarded after reaching their limited usage count. In this embodiment, when the chip 23 is in use (at which time both the chip 23 and the electrodes on the electrode strip are connected to the host), the chip 23 can also automatically record the usage count and usage duration of the corresponding electrode strip, thereby enabling the information storage device to record transportation parameters throughout its entire lifecycle, thus further expanding the applicability of this device.

[0041] See also Figures 1-3 In one embodiment of this utility model, the information storage device further includes a first insulating tube 3, which is sleeved on the outside of the conductive post 21 and inserted into the outer shell 1. The first insulating tube 3 not only provides insulation between the outer shell 1 and the conductive post 21, preventing conduction between them, but also supports the arrangement of the conductive post 21 within the outer shell 1.

[0042] For example, the top surface of the conductive post 21 is flush with the top surface of the housing 1.

[0043] Furthermore, the information storage device also includes a second insulating tube 4, which is coaxially connected to the first insulating tube 3. The second insulating tube 4 is located inside the outer casing 1, and the circuit board 22 is located inside the second insulating tube 4. The second insulating tube 4 further insulates the circuit board 22 from the outer casing 1, preventing electrical conduction between the circuit board 22 and the outer casing 1.

[0044] For example, the first insulating tube 3 and the second insulating tube 4 are connected by an insulating ring and are integrally formed, with the outer diameter of the second insulating tube 4 being larger than the outer diameter of the first insulating tube 3. In addition, the second insulating tube 4 is provided with a notch to allow the probe 24 to be avoided.

[0045] In another implementation of this utility model, both the inner peripheral wall of the outer shell 1 and the outer peripheral wall of the conductive post 21 are provided with an insulating varnish layer. The two insulating varnish layers are bonded together, so that the insulating varnish can also achieve the insulating connection between the outer shell 1 and the conductive post 21.

[0046] It should be noted that in other embodiments of this utility model, the connection and insulation between the outer shell 1 and the conductive post 21 can also be achieved by other insulating components, such as an insulating rod. This utility model does not limit this.

[0047] In this embodiment, the outer shell 1 includes an upper shell 11 and a base 12, which are detachably connected. The base 12 is used to be mounted on the base of the electrode strip. The conductive post 21 and the circuit board 22 are both located inside the upper shell 11, and one end of the probe 24 is in contact with the base 12.

[0048] In the above embodiment, the base 12 is small in size, making it easy to install and fix it on the baseband of the electrode strip in advance. After the base 12 is installed in place, the entire device can be installed by installing the upper shell 11 (the communication component 2 is pre-installed inside the upper shell 11).

[0049] Furthermore, one end of the upper shell 11 is sleeved on one end of the base 12, and one end of the upper shell 11 is threadedly engaged with one end of the base 12. The connection strength between the upper shell 11 and the base 12 can be guaranteed through the threaded connection between the two.

[0050] It should be noted that the upper shell 11 and the base 12 can also be connected by means of glue, welding or screws, and this utility model does not limit this connection.

[0051] In addition, the outer peripheral wall of the upper shell 11 has an annular groove 111, which makes it easier for the operator to hold the upper shell 11 and screw it.

[0052] In one embodiment of this utility model, a first connecting plate 121, coaxially arranged, is connected to the other end of the base 12. The outer diameter of the first connecting plate 121 is larger than the outer diameter of the base 12. The first connecting plate 121 is used for insertion onto the electrode strip. The first connecting plate 121 can be pre-embedded or clamped onto the base strip 100 of the electrode strip to increase the connection strength between the outer shell 1 and the electrode strip (see...). Figure 4 ).

[0053] For example, the base strip 100 of the electrode strip can be formed by injection molding or by bonding a multi-layer fabric structure.

[0054] In addition, a second connecting ring 112 is coaxially arranged at one end of the upper shell 11. The outer diameter of the second connecting ring 112 is larger than the outer diameter of the upper shell 11, and the second connecting ring 112 is arranged parallel to and spaced apart from the first connecting plate 121. At this time, the first connecting plate 121 and the second connecting ring 112 can cooperate to clamp the base strip 100 of the electrode strip, further increasing the connection strength between the outer shell 1 and the electrode strip.

[0055] In this embodiment, both the outer shell 1 and the conductive post 21 are made of metal or carbon. The metal material can be copper, aluminum, or an alloy, while the carbon material can be graphite or carbon fiber.

[0056] Alternatively, probe 24 can also adopt a spring-loaded structure, which can satisfy the requirement of elastic conduction.

[0057] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
