Description

Title of the invention: Clothing for carrying an electronic device Technical field

[0001] The present invention relates to a device for carrying an electronic device, in particular a heart rate recorder. The invention is also applicable to any electronic device sensitive to vibrations or movements of the human body, in particular of the thorax, when the carrying garment is worn. Prior art

[0002] Portable heart rate recorders are used in various cases to monitor the electrical activity of the heart over an extended period of time. Below are some common use cases: - Diagnosis of cardiac arrhythmias: Portable cardiac recorders, such as Holters, are used to detect and record cardiac arrhythmias that may not be present when performing a standard electrocardiogram (ECG). - Assessment of intermittent cardiac symptoms: When patients experience cardiac symptoms such as palpitations, dizziness, or fainting intermittently, a portable cardiac recorder can be used to record any abnormalities in heart rhythm that occur concurrently with the symptoms. - Post-stroke or post-infarction monitoring: patients who have had a stroke or myocardial infarction can be equipped with portable heart rate recorders to monitor rhythmic cardiac activity (diagnostic and prognostic interest). - Assessment of treatment response: Portable heart rate recorders are sometimes used to assess the effectiveness of treatment by recording cardiac activity before, during, and after the administration of medications or interventions. - Searching for the causes of unexplained fainting: Fainting, or loss of consciousness, can have various causes, including heart problems. Portable cardiac recorders help record cardiac activity during these episodes to identify the underlying cause. - Monitoring blood pressure and ECG: Some portable cardiac recorders integrate blood pressure measurement in addition to ECG recording, providing a more comprehensive view of the cardio- vascular state. - Evaluating heart-related sleep disorders: Some portable cardiac recorders can be used to monitor cardiac activity during sleep, contributing to the evaluation of heart-related sleep disorders.

[0003] In summary, portable cardiac recorders are valuable tools for diagnosing, monitoring and managing various cardiac problems, particularly those that occur intermittently or in response to specific stimuli.

[0004] Interpreting an electrocardiogram (ECG) can sometimes be complex due to several factors. Here are some reasons why an ECG can be difficult to interpret: - Normal variability: There is great variability in normal cardiac physiology. ECGs can show subtle variations from person to person, which can make it difficult to distinguish normal patterns from abnormalities. - Individual anatomical elements: the position of the heart in the chest, the size of the heart chambers and other individual anatomical factors can influence the appearance of the ECG (existence of proven cardiac pathology). - Electrical abnormalities: Non-cardiac electrical abnormalities, such as electromagnetic interference, can interfere with ECG readings. - External factors: Artifacts may be introduced by patient movement, muscle tremors, poor electrode connection, or other external factors.

[0005] Holter-type portable recorders are devices used to monitor the electrical activity of the heart over an extended period of time, at least 24 hours, with the duration extending up to 72 hours for continuous recordings and 21 days for event recorders. These compact devices are worn by patients during their normal daily activities, thus allowing an ECG to be recorded over an extended period.

[0006] A portable heart rate recorder comprises a recording box connected to conductive cables, the ends of which are each provided with an adhesive electrode placed on the patient's chest. These electrodes are generally fixed at specific locations to obtain precise electrical information from the heart. The common positions for placing the electrodes are as follows: one electrode located in the high pre-sternal region, one electrode located in the xiphoid region, one electrode located in the left lateral and submammary region when the configuration is three electrodes; two other additional electrodes can be arranged in the upper presternal region and another in the right latero-thoracic region when the configuration is five electrodes. We therefore understand that several wires circulate on all or part of the anterior face of the thorax.

[0007] The recording box of a Holter monitor is generally held on the patient to ensure stability during the recording period. The method of attachment may vary depending on the specific model of the recorder, but here are some commonly used methods: - Belt clip or pocket clip: Many Holter monitors are designed with a belt clip on the back, allowing the patient to attach the monitor to their waistband or clothing. Some models may also have a pocket clip for insertion into a special pocket. - Neck hanging: Some Holters are equipped with a strap or cord that allows the patient to wear the unit around their neck, like a pendant. This can be particularly convenient when attaching it to a belt is not possible or comfortable. - Cuff or shoulder strap: Some Holter recorder models may come with an adjustable cuff or shoulder strap. The unit is then attached to the patient's arm or shoulder. - Adhesive attachment: In some cases, the recording box can be attached directly to the skin using a special adhesive patch. This can be useful when other attachment methods are not practical or comfortable. - Chest harness: Some Holters use a chest harness, similar to a cardiac monitor harness, to hold the box in place on the patient's chest. - Combination of methods: Some models may offer multiple fixation options, allowing the patient to choose the method that best suits their preferences and comfort.

[0008] It is important that the recording box is properly secured to ensure the quality of the tracings. A secure fixation helps to minimize unwanted movements of the box, thus reducing artifacts and ensuring reliable and usable ECG data during subsequent analysis. Patients are generally informed on how to wear the recording box and on the need to report any problems related to fixation during the recording period. It is therefore understood that the maintenance of the device, corresponding to an external factor of artifact on the ECG, must be controlled as well as possible and as far as possible must be made independent of the attention paid by the patient to the instructions for use.

[0009] All current portable devices lead to the formation of artifacts in quantity important on an ECG that the cardiologist must interpret as such in order to be able to interpret the real cardiac signals. This can therefore significantly increase the time spent reading the tracings to provide a reliable medical opinion.

[0010] [Fig.l] illustrates a tracing in figure IA of a healthy carrier, figure 1B illustrates the supraventricular extrasystole and figure 1C illustrates the ventricular extrasystole. It is easily observed that there are numerous artifacts designated in XX.

[0011] The invention aims to address the problem of maintaining the recording box in a simple and effective manner while increasing the comfort of the wearer. Summary

[0012] To this end, the present document proposes a garment for carrying electronic equipment, in particular a heart rate recorder, comprising a ventral wall and a dorsal wall and a neckline connecting the dorsal and ventral walls, the ventral wall carrying a support wall connected to the neckline and carrying a housing wall forming with the support wall a housing for receiving said electronic equipment, said support wall and the housing wall being made of a non-elastic material and being surrounded by a part of the ventral wall which is elastically deformable.

[0013] Thus shaped, the support wall and the housing wall deform less than the rest of the ventral wall so that when the garment is worn, the support wall more or less retains its shape. The garment will be sized so that the ventral and dorsal walls ensure an anatomical and comfortable elastic tightening of the garment on the wearer. In this way, the garment remains in position on the wearer which allows the housing for receiving the electronic equipment to remain in a fixed position on the wearer's torso, that is to say in the middle and lower presternal region.

[0014] Said support wall and the housing wall are surrounded only partly by a part of the ventral wall since the support wall is connected to the neckline.

[0015] According to the invention, the support wall is connected on a first peripheral part to the neckline and the rest of the periphery thereof is connected to the ventral wall and surrounded by it.

[0016] In a variant, the support wall and the ventral wall may be made in two separate parts assembled to each other by any means such as a seam for example. Similarly, the housing wall may be formed separately from the support wall and / or the ventral wall and assembled by any means such as a seam for example.

[0017] In one embodiment, the ventral wall and the dorsal wall are made in a first material. The support wall may be made of a second material and the housing wall is made of a third material. The first material may be made of a non-woven material, such as, for example, jersey cotton (obtained by knitting, for example), the second material and the third material may be identical, for example, a woven or non-woven textile, provided that they are non-stretchable. The dorsal wall and the ventral wall may be entirely made of an elastically deformable material. The deformability of the dorsal wall and the ventral wall may be identical in the height and width directions.

[0018] The back wall and the ventral wall can be made of a mixture of 95% cotton and 5% elastane.

[0019] In one embodiment, the housing wall and the support wall are made by weaving warp and weft threads.

[0020] The support wall may comprise an upper edge directly connected, i.e. fixed, to the neckline. In this configuration, the neckline, the upper edge of the support wall and the ventral wall may be assembled, for example by sewing, to each other.

[0021] The term "textile" here refers to a woven or non-woven material. A non-woven textile can be defined by the ISO 9092 standard: non-wovens are randomly or directionally oriented fibers transformed into a web or format, consolidated and bonded by friction, and / or cohesion and / or adhesion. The present disclosure therefore relates to all textile materials, i.e. capable of forming a carrying garment.

[0022] The support wall and the housing wall can be secured directly to the ventral wall and independently of each other. They can also be secured to each other and the support wall is secured alone to the ventral wall so that the housing wall is not secured directly to the ventral wall.

[0023] The support wall may comprise an upper edge connected directly to the neckline over at least 20% of the periphery of the neckline, preferably between 20 and 50%, more particularly between 20 and 40%. The periphery of the neckline is measured on the internal periphery.

[0024] This connection makes it possible to connect the neckline and the support wall over a sufficiently large portion to properly distribute the stresses linked to the mass of the recorder. This connection will be made continuously over the entire upper edge of the support wall. This connection can be made by any means such as for example by sewing.

[0025] The support wall can be connected over its entire periphery to the ventral wall.

[0026] The surface area of ​​the support wall is greater than the surface area of ​​the housing wall so as to define a peripheral band surrounding the housing wall.

[0027] The garment being thus shaped, a strip of the support part surrounds the wall housing and allows the housing wall to be held rigidly, i.e. without deformation.

[0028] The peripheral strip may have a width of at least 5 mm, preferably at least 10 mm, preferably less than 30 mm. These values ​​ensure good retention of the housing wall on the support wall. The peripheral edge of the support wall must be sufficiently far from the armholes in order to maintain sufficient elastic deformation in the part of the ventral wall arranged laterally between the support wall and the armholes.

[0029] The peripheral strip of the support wall may comprise a lower opening opening into the interior of the garment.

[0030] The lower opening of the support wall can communicate with the exterior of the garment or with the interior of the housing.

[0031] The housing wall may comprise an opening, preferably formed in a lower peripheral edge, opening to the exterior of the garment.

[0032] In combination with the lower opening of the support part, the opening of the housing wall thus allows connecting wires of a heart rate recorder to be passed through and retrieved by hand before inserting them into the lower opening of the support part.

[0033] When the support wall covers the ventral wall, it is understood that the lower opening then passes through the ventral wall and the support wall.

[0034] The housing wall may comprise an upper free edge delimiting a passage for mounting the electronic device in the housing, this free edge comprising an elastic member shaped so as to ensure that the ends of said upper edge are brought together and to keep the heart rate recorder stationary in its housing.

[0035] The ventral wall, the support wall and the housing wall may be separate textile pieces, woven or non-woven, stacked successively so that the support wall is arranged between the ventral wall and the housing wall.

[0036] The portion of the support wall which faces the housing wall can be free to move relative to the ventral wall.

[0037] The support wall is thus free from attachment to the ventral wall in a central part of the support wall, which allows movement between the support wall and the ventral wall, which limits parasitic movements of the electronic device due to the movement of the wearer. When the device is a heart rate recorder, this makes it possible to reduce parasitic noise on the electrocardiogram.

[0038] The support wall may comprise at least one upper opening, preferably two openings spaced apart in a horizontal direction.

[0039] Said at least one upper opening can open into the interior of the housing.

[0040] The support wall may extend vertically at least to a horizontal line arranged below the armholes. The horizontal line may be arranged between 0.5 and 2.5 cm below the armhole.

[0041] The housing wall is preferably arranged above the lower ends of the armholes.

[0042] The housing wall will be sized so that the recorder does not descend below the xyphoid appendage. Thus, positioning the housing wall allows the recorder to be kept above the abdomen and prevents the abdominal movements of the latter from impacting the quality of the recording.

[0043] The present document also relates to an assembly comprising a heart rate recorder arranged inside the housing. The positions for placing the electrodes are as follows: one electrode located in the upper pre-sternal region, one electrode located in the xyphoid region, one being an electrode located in the left lateral and sub-mammary region when the configuration is with three electrodes; two other additional electrodes can be arranged in the upper pre-sternal region and another in the right latero-thoracic region when the configuration is with five electrodes.

[0044] The support wall may have any shape. In particular, the support wall may comprise four peripheral edges connected to each other, a first substantially rectilinear edge being connected at its respective ends to a respective second edge and third edge which are parallel to each other, the second and third edges being connected to a fourth upwardly concave rounded edge connected to the neckline.

[0045] The housing wall may have the shape of a quadrilateral. Brief description of the drawings

Description of the embodiments

[0053] Reference is made to [Fig. 2] which represents a garment 10 for carrying electronic equipment, in particular a heart rate recorder, comprising a ventral wall 12 and a dorsal wall (not visible) and a neckline 14 connecting the dorsal and ventral walls 12, the ventral wall 12 carrying a support wall 16 connected to the neckline 14 and carrying a housing wall 18 forming with the support wall 16 a housing for receiving said electronic equipment, said support wall 16 and the housing wall 18 being made of a non-elastic material and being surrounded by a part of the ventral wall 12 which is elastically deformable. In other words, the support wall is connected on a first peripheral part to the neckline and the rest of the periphery of the support wall is connected to the ventral wall and surrounded by it.

[0054] In the figures, the recorder 17 is connected to a first end of a wire 19, the opposite end of which carries an electrode 21 applied to the patient's chest.

[0055] In one embodiment of the invention, the dorsal wall, the ventral wall 12, the support wall 16 and the housing wall 18 are formed by weaving, for example from a cotton fiber, which makes it possible to achieve the desired differences in elasticity. Other fibers could be used.

[0056] The ventral wall 12, the support wall 16 and the housing wall 18 can be produced by a successive stacking of three separate pieces of fabric so that the support wall 16 is arranged between the ventral wall 12 and the housing wall 18.

[0057] As can be seen in the figures, the ventral wall 12 is made from a first piece of fabric as is the dorsal wall and has a first elasticity which is obtained by a first given weave. The neckline 14 has a second elasticity which can be identical to that of the ventral wall 12 and the dorsal wall. In practice, the deformation of the neckline 14 is limited by the sewing thread making the connection of a strip of fabric forming the neckline 14 with the ventral wall 12 and the dorsal wall.

[0058] The support wall 16 may be in the form of a non-elastic fabric plate, i.e. one which does not deform elastically in a visible or noticeable manner by hand. The support wall is deformable since it is flexible but cannot elastically elongate by stretching when a force is exerted in both directions of extension thereof, i.e. in the vertical and horizontal directions. rhizotal, parallel to the support wall. Similarly, the carrying garment comprises a housing wall 18 applied to the support wall 16. This housing wall 18 can be made of the same material as the support wall 16 and is also non-elastic.

[0059] The support wall 16 comprises four sides, a substantially horizontal lower edge 18b, two substantially vertical lateral edges 16b parallel to each other and substantially perpendicular to the lower edge. The two lateral edges 16b are connected to a concave upper edge 18c which is directly connected to the neckline. Preferably, the connection of the support wall 16, in particular the concave upper edge 18c, to the neckline 14 is made over at least 20% of the periphery of the neckline, preferably between 20 and 50%, more particularly between 20 and 40%.

[0060] The housing wall 18 comprises an upper free edge 18a delimiting a passage for mounting the electronic device in the housing, this free edge 18a comprising an elastic member shaped so as to ensure that the ends of said upper edge are brought together. It is observed that the housing wall 18 may have a substantially rectangular shape.

[0061] In the embodiment shown in the figures, the support wall 16 is fixed over its entire periphery, by a first seam, to the ventral wall 12. The housing wall 18 is fixed to the support wall to the ventral wall 12 by a second peripheral seam surrounded by the first peripheral seam.

[0062] It is observed that a peripheral strip 20 surrounds the housing wall 18 and is formed by a portion of the support wall 16 and is delimited by the lateral edges 16b and the facing edges of the housing wall 16 and by the lower edge 16a and the lower edge 18b of the facing housing wall 18. The surface area of ​​the support wall 16 is thus greater than the surface area of ​​the housing wall 18. The peripheral strip 20 may have a width of at least 1 cm.

[0063] As illustrated, the peripheral strip 20 of the support wall 18 includes an interior opening 22 opening into the interior of the garment. The lower edge 18b of the housing wall 18 also includes a lower opening 24 opening into the exterior of the housing and into the exterior of the garment so that a connection wire of a heart rate recorder mounted inside the housing can pass through the lower opening 24 of the lower edge 18b of the housing wall 18 and into the opening 22 of the peripheral strip 20 of the support wall 16. Thus, the wire circulates only slightly on the body of a wearer (the white electrode cable intended to be connected in the upper presternal region) which limits the parasitic noise recorded by the device and the contacts of the white electrode cable with the skin of the wearer.

[0064] In an alternative embodiment shown in [Fig.5], at least one upper opening 26, preferably two openings 25, 26 spaced along a direction ho rhizotal, are formed in the support wall 16 and the ventral wall 12. These openings 26 allow the white electrode cable to pass through the upper presternal region. It is observed that the wire 19 passing through the opening 26 and connected to an electrode 21 comprises a first part 19a housed inside the housing and a second part 19b circulating between the ventral wall and the body of a wearer.

[0065] [Fig.6] illustrates the gain obtained with the invention, in [Fig.6] is represented the ECG of the same wearer as in figure 1A. We observe in figure 1B showing the atrial extrasystole and figure 1C showing the ventricular extrasystole that there are almost no more false detections. In practice, the invention makes it possible to reduce the number of artifacts by a factor of 100, allowing a cardiologist to save significant time.

[0066] It is observed that the support wall extends vertically at least up to a horizontal line arranged below the armholes. This line can be arranged between 0.5 and 2.5 cm below the armhole.

[0067] In this document, the terms vertical and horizontal are to be considered when the carrying garment is worn by a wearer in a standing position.
