[0036] With reference to Figure 1 and Figure 2 The present application provides a wearable defibrillation device. The device comprises a clothes for a patient to wear, an electrocardio electrode, a host, a defibrillation electrode system 100; at least two said electrocardio electrodes are sewn on the clothes, the clothes are sewn with at least two accommodating bags, the defibrillation electrode system 100 is inserted into the accommodating bag; the electrocardio electrode and the defibrillation electrode system 100 are respectively electrically connected with the host.
[0037] The present application is a wearable defibrillation electrode system 100, which is used for patients who are going to have a heart surgery or are in the recovery period of a heart surgery. The system can collect the ECG signals of the patient in real time through the ECG electrodes, and can identify and analyze the collected ECG signals to determine whether the patient has a disease. If the patient has a disease, the system can output a current with a certain energy through the heart to perform a defibrillation treatment, so as to eliminate the disease or alleviate the symptoms and win time for the patient. Thus, the patient does not need to be hospitalized, and can be treated in time when the disease occurs. Therefore, the medical expenses of the patient can be reduced, and the life quality of the patient can be improved.
[0038] With reference to Figure 1 and Figure 2 , and Figures 4 to 7 , the wearable defibrillation electrode system 100 of the present application comprises a gel container assembly 3, a conductive sheet 2 and a control assembly 5; the conductive gel is sealed in the gel container assembly 3; the conductive sheet 2, the gel container assembly 3 and the control assembly 5 are stacked from bottom to top.
[0039] Specifically, the lower surface of the gel container assembly 3 is a plane, the lower surface of the gel container assembly 3 is connected with the upper surface of the conductive sheet 2 in a fit manner; the lower surface of the control assembly 5 is connected with the upper surface of the gel container assembly 3.
[0040] With reference to Figures 4 to 6 , the conductive sheet 2 is provided with a plurality of gel injection holes 21 penetrating the upper surface and the lower surface thereof, and the gel injection holes are connected with the system. When the system works, the control assembly 5 can drive the conductive gel in the gel container assembly 3 to pass through the gel injection holes 21, and each gel injection hole 21 releases the conductive gel, so that the conductive gel is coated at the contact position between the conductive sheet 2 and the skin of the patient. When the patient has a disease, the wearable defibrillation electrode system 100 outputs a current with a certain energy through the heart to perform a defibrillation treatment, which does not damage the skin of the patient and can improve the defibrillation treatment effect.
[0041] The conductive sheet 2 is made of metal and is relatively thin, and the edge thereof is relatively sharp. After the conductive sheet 2, the gel container assembly 3 and the control assembly 5 are stacked from bottom to top, a ring-shaped pressure layer sheet 1 is attached to the edge of the lower surface of the conductive sheet 2. The edge of the conductive sheet 2 is not protruded from the outer edge of the ring-shaped pressure layer sheet 1, and is not protruded from the edge of the gel container assembly 3 and / or the control assembly 5. Thus, the edge of the conductive sheet 2 is hidden or wrapped, and does not expose, so that the conductive sheet 2 does not cut the skin when the wearable defibrillation electrode system is taken out or placed.
[0042] With reference to Figures 1 to 7One embodiment of the present application discloses that the outer dimensions of the conductive sheet 2, the ring-shaped pressure sheet 1, the gel container assembly 3, and the control assembly 5 are all the same. When the conductive sheet 2, the ring-shaped pressure sheet 1, the gel container assembly 3, and the control assembly 5 are stacked together, the edges of the conductive sheet 2, the outer edges of the ring-shaped pressure sheet 1, the edges of the gel container assembly 3, and the edges of the control assembly 5 are all aligned with the edges of the conductive sheet 2. The edges of the conductive sheet 2 are thus hidden and not exposed, so the conductive sheet 2 will not cut the skin when the defibrillation electrode system is taken out or put in.
[0043] Reference is made to Figures 1 to 7 Another embodiment of the present application discloses that the outer dimensions of the ring-shaped pressure sheet 1, the gel container assembly 3, and the control assembly 5 are all slightly larger than the outer dimensions of the conductive sheet 2. When the conductive sheet 2, the ring-shaped pressure sheet 1, the gel container assembly 3, and the control assembly 5 are stacked together, the edges of the conductive sheet 2 are in a wrapped state and not exposed, so the conductive sheet 2 will not cut the skin when the defibrillation electrode system is taken out or put in.
[0044] Reference is made to Figures 1 to 7 Another embodiment of the present application discloses that the outer dimensions of one of the gel container assembly 3 and the control assembly 5 are equal to the outer dimensions of the ring-shaped pressure sheet 1; when stacked together; the outer edges of the ring-shaped pressure sheet 1 are aligned with its edges. Meanwhile, the outer dimensions of the conductive sheet 2 are equal to the outer dimensions of the ring-shaped pressure sheet 1; when the conductive sheet 2, the ring-shaped pressure sheet 1, the gel container assembly 3, and the control assembly 5 are stacked together, the conductive sheet 2 is not exposed, so the conductive sheet 2 will not cut the skin when the defibrillation electrode system is taken out or put in.
[0045] The outer dimensions of one of the gel container assembly 3 and the control assembly 5 are equal to the outer dimensions of the ring-shaped pressure sheet 1; when stacked together; the outer edges of the ring-shaped pressure sheet 1 are aligned with its edges; meanwhile, the outer dimensions of the conductive sheet 2 are slightly smaller than the outer dimensions of the ring-shaped pressure sheet 1; so the conductive sheet 2 is not exposed.
[0046] The edges of the conductive sheet 2 are provided with a plurality of connecting holes 22. Preferably, the plurality of connecting holes 22 are uniformly distributed along the edges of the conductive sheet 2. When the edges of the conductive sheet 2 are connected with the ring-shaped pressure sheet 1, the connecting holes 22 are distributed in their connecting areas, see Figure 4 .
[0047] Preferably, the ring-shaped pressure layer 1 and the sealing layer 31 are both made of low-density polyethylene. The connecting hole 22 facilitates the edges of the conductive sheet 2 and the ring-shaped pressure layer 1 to be connected together by laser welding.
[0048] In addition, for the convenience of connecting the cable, with reference to Figure 4 and Figure 5 , a part of the side surface of the conductive sheet 2 extends to form a connecting piece 23, the connecting piece 23 has a connecting end and a free end, the connecting end is smoothly connected with the conductive sheet 2; the free end is provided with a through hole 24; the control assembly 5 and the gel container assembly 3 are respectively provided with an assembly hole 4. When assembled, the free end of the connecting piece 23 is suspended above the defibrillation electrode system 100 after passing through the corresponding assembly holes 4 of the gel container assembly 3 and the control assembly 5, the through hole 24 is detachably connected with a cable, preferably, the through hole 24 is detachably connected with one end of the cable by a screw. The other end of the cable is connected with the host computer, so that the conductive sheet 2 is electrically connected with the host computer, and the conductive sheet 2 is reliably connected with the host computer. Preferably, the connecting piece 23 is suspended above a corner position of the defibrillation electrode system 100.
[0049] With reference to Figure 7 , the gel container assembly 3 of the present application comprises a base layer and a sealing layer 31; the base layer is provided with a plurality of gel chambers on the side facing the sealing layer 31; when the sealing layer 31 and the base layer are assembled together, the gel chambers are sealed.
[0050] With reference to Figure 7 , the sealing layer 31 is provided with a plurality of through holes 32; the through holes 32 correspond one-to-one to the gel chambers. Preferably, the plurality of through holes 32 are arranged in a rectangular array, specifically, at least two columns and at least five rows; most preferably, the plurality of through holes 32 are arranged in two columns and five rows.
[0051] The glue injection hole 21 corresponds one-to-one to the through hole 32 and the gel chamber; and the orthogonal projection of the through hole 32 on the conductive sheet 2 intersects with the glue injection hole 21; in other words, the orthogonal projection of the through hole 32 on the conductive sheet 2 covers part of the glue injection hole 21; when the system is not working, the through holes 32 are all in a sealed state.
[0052] With reference to Figure 2 , the control assembly 5 of the present application comprises a shell 51 and a gas source 52; the lower surface of the shell 51 is connected with the upper surface of the gel container assembly 3, and each of the gel chambers is surrounded by the shell 51 to form a power sealed cavity; all the power sealed cavities are communicated with the gas source 52 through a gas path 53.
[0053] When the system works, i.e. when the defibrillation treatment is carried out; the gas source 52 inputs gas into the sealed cavity; the pressure in the sealed cavity increases rapidly, thereby exerting pressure on the gel chamber, forcing the conductive gel in the gel chamber to move to the conductive sheet 2, and the seal of the through hole 32 is broken, finally the conductive gel is released through the through hole 32 and the gel injection hole 21, so that the conductive gel is coated on the position where the conductive sheet 2 contacts the skin of the patient.
[0054] Compared with the prior art, the defibrillation electrode system 100 and the wearable defibrillation device of the present application, since the control assembly 5, the gel container assembly 3 and the conductive sheet 2 are processed and attached together, and the edge of the lower surface of the conductive sheet 2 is attached with the annular pressure layer sheet 1, and the edge of the conductive sheet 2 does not protrude beyond the outer edge of the annular pressure layer sheet 1, and does not protrude beyond the edge of the gel container assembly 3 and / or the control assembly 5; the conductive sheet 2 itself is very thin, which can make the edge of the conductive sheet 2 not leak out, thereby effectively solving the problem of hand being cut during the process of taking and placing the defibrillation electrode system 100.
[0055] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
