As shown in connection with figures 6 to 14,
the far surface of the bracket main body 21 is provided with an LA detection electrode 211 and an RA detection electrode 212 corresponding to the left arm and the right arm of the user to be detected respectively, and the near surface is provided with a V3 detection electrode 213 and an RL detection electrode 214; the detecting electrode bracket 2 further comprises an upper bracket arm 22 connected to the upper edge of the bracket main body 21, and a V1 detecting electrode 221 and a V2 detecting electrode 222 are arranged on the proximal surface thereof; a lower support arm 23 connected to the lower edge of the support main 21, and provided with an LL detection electrode 231 on the proximal surface thereof; a side support arm 24, the side support arm 24 is connected to the left side edge of the support main body 21 to correspond to the chest side where the heart of the user to be detected is located, the proximal surface of the side support arm 24 is provided with a V4 detection electrode 241, a V5 detection electrode 242 and a V6 detection electrode 243, and the upper support arm 22, the lower support arm 23 and the side support arm 24 can all turn around the connection positions with the support main body 21 towards the proximal surface of the support main body 21 by a target angle.
The upper edge, the lower edge and the left edge are determined by the orientation of the electrocardiograph of the present application relative to the user to be detected in the use state, and the target angle is limited by the maximum angle at which the lower support arm 23, the lower support arm 23 and the side support arm 24 can be turned near the proximal surface of the support main body 21, so that the storage of each support arm is more compact, in a specific embodiment, the target angle at which the upper support arm 22 and the lower support arm 23 can be turned should be not less than 90 ° and the target angle at which the side support arm 24 can be turned should be not less than 120 °. The above-mentioned ten detection electrodes, namely LA detection electrode 211, RA detection electrode 212, V3 detection electrode 213, RL detection electrode 214, V1 detection electrode 221, V2 detection electrode 222, LL detection electrode 231, V4 detection electrode 241, V5 detection electrode 242 and V6 detection electrode 243, are named as the relevant detection electrodes (columns or sheets) of the conventional twelve-lead electrocardiograph detector, and the arrangement positions of the detection electrodes are according to the ergonomic design, so as to meet the requirements of the known twelve-lead wilson positioning system, and the application is not particularly limited thereto.
In the technical scheme, ten detection electrodes are reasonably arranged on the bracket main body 21, the upper bracket arm 22, the lower bracket arm 23 and the side bracket arm 24 according to the electrocardiograph detection positions, and corresponding electrode wires are arranged inside the bracket, so that the structure is compact, and the winding problem caused by long cables in the prior art is avoided; each support arm can be connected to the corresponding edge of the support main body 21 in a turnover manner, when a user to be detected detects the electrocardio, each support arm can be unfolded and positioned easily, the operation of a professional is not needed, the user to be detected can position and complete the electrocardio detection only according to the reference positioning standard on the support main body 21, the operation detection is easy to implement, the progress of advancing the electrocardiograph into the home is facilitated, and the electrocardiograph can be detected by the patient at home; when the electrocardiograph is not required to be detected, the support arms are turned and folded towards one side close to the body surface of the support main body 21, so that the support arms are quickly stored, and the electrocardiograph in a storage state is compact in structure; it should be noted that, the detection surface of each detection electrode on each support arm in the folded and flipped state will face the proximal surface of the support main body 21, and the detection electrodes are hidden inward as a whole, which can protect the detection electrodes and effectively reduce the damage probability caused by abrasion or drop of each detection electrode.
The proximal surface refers to a side wall surface of the electrocardiograph, which is close to the user to be detected in the use state, and the distal surface refers to a side wall surface of the user to be detected in the use state, wherein the proximal surface and the distal surface are opposite to each other.
The upper support arm 22, the lower support arm 23 and the side support arm 24 can be connected with the support body 21 in a reversible manner by conventional torque shaft structures (not shown and not labeled in the drawings), and each torque shaft structure can apply force to each corresponding support arm to enable each support arm to have a tendency of turning towards the turning storage state when the electrocardiograph is in the electrocardiograph detection state.
To ensure the position of each detection electrode, the length of the side support arm 24 is designed to be longer, while the lengths of the upper support arm 22 and the lower support arm 23 are designed to be relatively shorter.
In some embodiments of the present application, in some embodiments,
the side support arm 24 has a detection position (corresponding to an electrocardiographic detection state) and a storage position (corresponding to an electrocardiographic inversion storage state), when the side support arm 24 is at the detection position, the V4 detection electrode 241, the V5 detection electrode 242, and the V6 detection electrode 243 are each at a preset electrocardiographic detection position, and when the side support arm 24 is at the storage position, the lock key 25 locks the side support arm 24 so that the proximal surface of the side support arm 24 is opposite to the proximal surface of the support main body 21.
Because the three detection electrodes are arranged on the side support arm 24, and the length of the detection electrodes is relatively large, the self mass of the detection electrodes is relatively large, the torsion rotating shaft structure between the detection electrodes and the support main body 21 is weakened when the detection electrodes are used for a long time, the side support arm 24 cannot be reliably and stably positioned at the storage position, the loose state reduces the use satisfaction of a user, and more importantly, the corresponding detection electrodes are extremely easy to collide with an external object randomly due to the unreliability of the storage position, so that the detection electrodes are damaged.
As shown in connection with figures 11 to 14,
the V4 detection electrode 241, the V5 detection electrode 242, and the V6 detection electrode 243 are disposed at intervals along the length direction of the arm body of the side support arm 24 from a side close to the support main 21 toward a side far away from the support main 21, the lock key 25 further has a second locking position and a second unlocking position, the V6 detection electrode 243 has a ring groove 2431, the lock key 25 has a second protrusion 251, when the side support arm 24 is in the storage position, the second protrusion 251 is at least partially inserted into the ring groove 2431 to be in the second locking position, and when the lock key 25 is in the second unlocking position, the second protrusion 251 is disengaged from the ring groove 2431.
In this technical scheme, through the concave-convex matching structure of the second protrusion 251 on the locking key 25 and the annular groove 2431 on the V6 detection electrode 243, the locking of the opposite side support arm 24 is realized, the structure is simple, and the locking operation is convenient, so that the locking key 25 in the application can simultaneously realize the locking purposes of the opposite side support arm 24 and the host part 11, the structural design of the electrocardiograph is simplified, and the integral structure of the detection electrode support can be further compact.
In some embodiments of the present application, in some embodiments,
an elastic member 254 is provided between the lock key 25 and the holder main body 21, and the elastic member 254 is capable of applying an elastic force to the lock key 25 so that the lock key 25 can slide near the V6 detection electrode 243 in the storage position and the host member 11 in the mounting position;
when the electrocardiograph is needed to be used for electrocardiograph detection, a user applies force to the locking key 25 to overcome the elastic force applied by the elastic piece 254, so that the locking key 25 is driven to slide away from the V6 detection electrode 243 and the host component 11, at the moment, the second protrusion 251 is separated from the annular groove 2431 and/or the first protrusion 252 is separated from the groove, so that the locking of the opposite side support arm 24 and/or the host component 11 is released, the electrocardiograph can be in an electrocardiograph detection state, when the host component 11 or the side support arm 24 is needed to be locked, the user only needs to press the host component 11 or the side support arm 24, and when the position of the groove or the annular groove 2431 corresponds to the position of the first protrusion 252 or the second protrusion 251, the locking key 25 slides close to the host component 11 or the side support arm 24 under the elastic force of the elastic piece 254, and then the clamping locking of the components is realized, and the operation is very simple and convenient. In a preferred embodiment, the locking key 25 has a force-applying protrusion 253 protruding from the proximal surface of the holder main body 21, and when the user needs to unlock the opposite holder arm 24 and the main body member 11, the user can simply and conveniently apply force to the force-applying protrusion 253 in a direction away from the former members. The elastic member 254 may be a coil spring.
In some embodiments of the present application, in some embodiments,
the depth of the second protrusion 251 and the groove 2431 is smaller than the depth of the first protrusion 252 and the groove, so, by designing the depth of the second protrusion 251 and the groove 2431 to be smaller than the depth of the first protrusion 252 and the groove, the host component 11 can not be unlocked while the side support arm 24 is unlocked, specifically, the locking key 25 is far away from the sliding and has two distances, the unlocking side support arm 24 can be realized by sliding in a short distance, the electrocardiograph detection can be performed, the host component 11 can be unlocked by sliding in a long distance, the host can be replaced at this time, and it is required to say that the locking key 25 can apply a larger force due to the compression elastic force of the elastic piece 254 when sliding in a long distance, so that the host component 11 can be effectively prevented from being unlocked by mistake when the electrocardiograph detection is performed by the unlocking side support arm 24, and the host component 11 is prevented from being accidentally falling down and damaged. As a preferred embodiment, the proximal edge of the side support arm 24 has a third protrusion (not shown) that engages the V1 detection electrode 221, the V2 detection electrode 222, and the LL detection electrode 231 to prevent the upper support arm 22 and the lower support arm 23 from tipping away from the support body 21 when the side support arm 24, the upper support arm 22, and the lower support arm 23 are in the storage position.
In this technical scheme, when the electrocardiograph is in the upset state of accomodating, the side support arm 24 realizes the interlocking spacing to upper support arm 22 and lower support arm 23 through the third arch, can prevent that upper support arm 22 and lower support arm 23 from keeping away from support main part 21 upset under the folding state of accomodating, each detection electrode on upper support arm 22 and the lower support arm 23. As such, it can be appreciated that when stowing each of the support arms, the upper support arm 22 and the lower support arm 23 should first be flipped in place and then the side support arm 24 flipped so that the side support arm 24 is objectively blocked from the everting path of the upper support arm 22 and the lower support arm 23.
