DETAILED DESCRIPTION

[0025] The technical solutions of the present application will be described clearly and completely in the embodiments combined with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative effort shall fall within the scope of the present application.

[0026] Please refer to Figure 1 and Figure 2The embodiment of the present application provides a lead mattress for collecting electrocardiogram signals, which comprises a lead mattress body 1, a plurality of lead wires 4 and a signal processor. Figure 3 The lead mattress body 1 comprises a base layer 8, an outer side of the base layer 8 is provided with a shielding layer 9, and an outer side of the shielding layer 9 is provided with an insulating layer 7; a part of each lead wire 4 is wrapped in the base layer 8, and another part is led out of the lead mattress body 1 to be connected to an electrode assembly 3; and the signal processor is arranged on the lead mattress body 1 and connected to the lead wires 4.

[0027] The lead mattress for collecting electrocardiogram signals is especially suitable for a fixed scene such as an examination room. Figure 3 Since the lead wires 4 are partially wrapped in the base layer 8, the wrapped lead wires 4 are fixed on the lead mattress and cannot be moved, and the lead mattress is laid on a hospital bed, so that the lead wires 4 do not need to be additionally stored, and the curling / bending / pulling of the lead wires 4 is naturally reduced.

[0028] In some embodiments, referring to Figure 1 The plurality of lead wires 4 comprises a first lead wire 41, a second lead wire 42, a third lead wire 43, a fourth lead wire 44 and a fifth lead wire 45. In actual application, the first lead wire can be referred to as an R lead wire, the second lead wire can be referred to as an L lead wire, the third lead wire can be referred to as an N lead wire, the fourth lead wire can be referred to as an F lead wire, and the above four can be collectively referred to as four limb lead wires, and the fifth lead wire can be referred to as a chest lead wire.

[0029] Here, the electrode assembly 3 comprises a right upper electrode clamp 31, a left upper electrode clamp 32, a right lower electrode clamp 33, a left lower electrode clamp 34 and a chest lead suction ball electrode assembly 35; the first exposed part of the first lead wire 41 exposed outside the lead mattress body 1 is connected to the right upper electrode clamp 31, the second exposed part of the second lead wire 42 exposed outside the lead mattress body 1 is connected to the left upper electrode clamp 32, the third exposed part of the third lead wire 43 exposed outside the lead mattress body 1 is connected to the right lower electrode clamp 33, the fourth exposed part of the fourth lead wire 44 exposed outside the lead mattress body 1 is connected to the left lower electrode clamp 34, and the fifth exposed part of the fifth lead wire 45 exposed outside the lead mattress body 1 is connected to the chest lead suction ball electrode assembly 35.

[0030] Exemplarily, the lengths of the first exposed part and the second exposed part are greater than or equal to the lengths of the third exposed part and the fourth exposed part.

[0031] For example, the length of the first exposed part and the second exposed part ranges from 25cm to 35cm; the length of the third exposed part and the fourth exposed part ranges from 15cm to 25cm.

[0032] In this way, the length of each lead wire 4 leading-out part (i.e. the first exposed part, the second exposed part, the third exposed part and the fourth exposed part) is short, which helps to avoid entanglement, and the length of the leading-out of each lead wire 4 is also considered in the case of self-installation of the electrode by the patient, i.e. the length of the lead wire 4 in the hand region is longer than that in the foot region, so that the user can self-install.

[0033] Here, a lying area can be provided on the upper surface of the lead bed body 1, which can be used for the patient to lie down for examination, and a generally human-shaped marking line can be provided along the edge at the lying area, and of course the marking line is not necessary. The lying area and other areas of the upper surface of the lead bed body 1 can be a connected whole plane, and of course the lying area can also be concave compared to other areas of the upper surface of the lead bed body 1, etc.

[0034] At a position close to the right hand of the lying area on the lead bed body 1, a part (i.e. the first exposed part) of the first lead wire 41 is thus led out of the lead bed body 1, and the remaining part of the first lead wire 41 is wrapped in the lead bed body 1, so that the remaining part of the first lead wire 41 is fixed and cannot move, and is also not easy to bend and entangle.

[0035] Similarly, at a position close to the left hand of the lying area on the lead bed body 1, a part (i.e. the second exposed part) of the second lead wire 42 is thus led out of the lead bed body 1, and the remaining part of the second lead wire 42 is wrapped in the lead bed body 1; at a position close to the right foot of the lying area on the lead bed body 1, a part (i.e. the third exposed part) of the third lead wire 43 is thus led out of the lead bed body 1, and the remaining part of the third lead wire 43 is wrapped in the lead bed body 1; at a position close to the right foot of the lying area on the lead bed body 1, a part (i.e. the fourth exposed part) of the fourth lead wire 44 is thus led out of the lead bed body 1, and the remaining part of the fourth lead wire 44 is wrapped in the lead bed body 1.

[0036] In some embodiments, referring to Figure 3 The utility model also includes pressure sensor 10, pressure sensor 10 with signal processor signal is connected;Pressure sensor 10 sets up between the base layer 8 or the base layer 8 with shielding layer 9. Figure 3In some embodiments, the pressure sensor 10 is arranged between the base layer 8 and the shielding layer 9, specifically, a portion of the pressure sensor 10 is arranged in the base layer 8 and another portion of the pressure sensor 10 is arranged in the shielding layer 9.

[0037] With the arrangement of the pressure sensor 10, in actual use, the ECG signal acquisition can be automatically started after the pressure signal of the patient lying down is detected by the pressure sensor 10, and the signal processor enters a sleep state when no pressure signal is detected. Thus, the pressure sensor 10 can automatically start / stop measurement, ensure that data acquisition and transmission are only performed when the patient lies down, maximize the power saving, and improve the endurance time of the lead bed pad for acquiring ECG signals provided by the embodiments.

[0038] In some embodiments, the signal processor comprises a wireless transmission circuit for wireless signal transmission with the ECG machine.

[0039] Here, the signal processor transmits signals with the ECG machine in a wireless manner, which not only simplifies the wiring harness, but also avoids interference signals from the ECG machine mixing into the signal processor circuit, especially reducing the mixing of interference signals into the sensitive signal amplification circuit of the signal processor. At the same time, after the wireless mode is adopted, the alternating current power connected to the ECG machine is not directly connected to the signal processor of the lead bed pad in a wired form, and the safety risk that may be caused by the alternating current power supply can also be avoided.

[0040] In some embodiments, please continue to refer to Figure 3 The lead bed pad body 1 comprises, from inside to outside, the base layer 8, the shielding layer 9, and the insulation layer 7. Specifically, the upper and lower sides of the base layer 8 are respectively provided with the shielding layer 9, and the outer side of the shielding layer 9 away from the base layer 8 is provided with the insulation layer 7. Exemplarily, it can form a layered structure arranged in sequence from top to bottom as one insulation layer 7, one shielding layer 9, one base layer 8, one shielding layer 9, and one insulation layer 7.

[0041] Among them, each layer of material should be made of soft and bend-resistant material as much as possible. For example, the base layer 8 and the insulation layer 7 are made of rubber, and exemplarily, natural rubber or other soft materials with insulation and antibacterial properties similar to TPE material (thermoplastic elastomer) can be used. The shielding layer 9 can be made of graphene TPE composite material or nano-metal material.

[0042] In use, a portion of each lead wire 4 is wrapped in the base layer 8, and the base layer 8 can provide sufficient mechanical support performance to avoid the patient's body weight concentrated on the lead wire 4. The insulation layer 7 can be made of insulating and antibacterial material to avoid yellowing or blackening or causing stains after long use.

[0043] In some embodiments, the shielding layer 9 can also be connected to the ground terminal of the circuit of the signal processor to realize the grounding function.

[0044] In some embodiments, referring to Figure 5 , the chest lead suction ball electrode assembly 35 includes six chest lead suction balls 351, and the six chest lead suction balls 351 are sequentially and spacedly arranged on a flexible connecting member 352. Meanwhile, the fifth lead wire 45 includes six branches respectively connected to the six chest lead suction balls 351.

[0045] Exemplarily, the flexible connecting member 352 is made of resin material, and the six chest lead suction balls 351 are sequentially mounted on the flexible connecting member 352.

[0046] Thus, in use, referring to Figure 6 , the chest lead suction balls 351 only need to be sequentially and individually mounted on the patient from one end, and the electrodes of the chest lead suction balls 351 do not need to be identified one by one.

[0047] In some embodiments, referring to Figure 1 and Figure 2 , the one end of the lead bed pad body 1 is provided with a protective shell 2, and the signal processor is arranged at the protective shell 2. Thus, the protective shell 2 and the signal processor jointly constitute an electrocardiosignal acquisition box, and the protective shell 2 can protect the signal processor. The signal processor can be further provided with signal acquisition, amplification circuit, analog-digital conversion, wireless transmission and other circuit modules, and it can be understood that these circuit modules are all known structures. In addition, referring to Figure 1 , in some examples, an electrocardiosignal transmission line socket 6 can also be arranged, and referring to Figure 4 , the signal processor can perform data transmission with the electrocardiograph in wired and wireless modes.

[0048] The lead bed pad for acquiring electrocardiosignal provided by the embodiments of the present application discards the traditional long lead wire design, embeds the lead wire 4 into the whole lead bed pad, and only draws a small section of the lead wire 4 and the electrode assembly 3 with sufficient length at the end of the limbs and near the left chest. Meanwhile, the signal processor is also integrated and arranged at one end of the lead bed pad. The shielding layer 9 is added in the middle of the lead bed pad to improve the anti-interference ability of the signal. Further, the pressure sensor 10 can also be added in the middle of the lead bed pad, so that the signal processor controls the electrode assembly 3 to work only when the patient lies down, and the endurance of the signal processor is maximized.
