Description

Technical Field

[0002] In wearable defibrillator devices, due to the wearing requirements, defibrillator electrodes cannot be attached to the skin for a long time using gel electrodes. However, when defibrillation is needed, the intermediate surface between the defibrillator electrode and the skin must be coated with defibrillator conductive gel to establish a temporary gel electrode to prevent the defibrillator high voltage from generating sparks and burning the skin near the skin, and to avoid energy loss near the skin contact so that there is enough energy for effective defibrillation. In this case, a conductive gel spraying system is needed, which can reliably store the conductive gel when defibrillation treatment is not needed, and can quickly spray the conductive gel onto the skin when treatment is needed.

[0003] In the prior art, the structure of the conductive gel spraying system is relatively complex. It requires a special process such as gunpowder or other chemical reactions to generate a pressure gas source, which then drives the conductive gel to be sprayed out. It has high requirements for materials and equipment, and the cost of R&D investment and verification testing is high, resulting in high product costs and complex installation processes.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a conductive gel release mechanism, including a receiving chamber, an elastic capsule 5, a pre-pressing component and a puncturing component. The elastic capsule 5 is arranged in the receiving chamber, and a conductive gel 4 is arranged inside the elastic capsule 5. Since the elastic capsule 5 has the characteristic of expansion under force, when the conductive gel 4 is loaded, the elastic capsule 5 is expanded, and under the action of the conductive gel 4, the elastic capsule 5 is kept in the expanded state. A glue outlet 11 is arranged in the receiving chamber to facilitate the flow of the conductive gel 4 in the elastic capsule 5.

[0037] The preload component is used to provide a preload force, under the action of which the accommodating cavity can shrink, and the holding force applied by the elastic bladder 5 in the expanded state to the accommodating cavity is balanced with the preload force applied by the preload component to the accommodating cavity, thereby matching the size of the accommodating cavity with the size of the loaded elastic bladder 5.

[0038] The puncturing component is used to puncture the elastic capsule 5 so that the conductive gel 4 in the elastic capsule 5 loses the wrapping effect of the elastic capsule 5 and diffuses into the accommodating cavity, while breaking the pressure balance in the accommodating cavity, causing the accommodating cavity to lose the holding force of the elastic capsule 5, and then the pre-pressing component drives the accommodating cavity to start shrinking, and the conductive gel 4 in the accommodating cavity is discharged from the gel outlet 11, thereby completing the release of the conductive gel 4.

[0039] It should be noted that the elastic capsule 5 is made of a material with uniform thickness and strength. After the elastic capsule 5 is filled with the conductive gel 4 that fits the accommodating cavity, there is pressure inside the elastic capsule 5. The elastic capsule 5 can withstand the internal pressure. At the same time, the elastic capsule 5 is also subjected to the pressure of the preload component (i.e., preload force). The material of the elastic capsule 5 needs to be able to maintain long-term stress. For example, the stress of the elastic capsule 5 can remain unchanged within 8 years. Under the premise of ensuring strength and pressure resistance, the elastic deformation of the elastic capsule 5 is very large. For example, when the elastic capsule 5 is changed from a state where the internal conductive gel 4 is not filled to a state where the conductive gel 4 is filled, the volume of the elastic capsule 5 increases by 50 times, so that after the elastic capsule 5 is punctured, the conductive gel 4 can quickly diffuse into the entire accommodating cavity, so as to flow out from the glue outlet 11.

[0040] With such arrangement, by puncturing the elastic capsule 5 in the accommodating cavity, the conductive gel 4 in the elastic capsule 5 can flow out from the gel outlet 11 under the action of the pre-pressing component, without the involvement of an air pressure source, with a simple structure and low cost.

[0041] In this solution, the conductive gel release mechanism includes a defibrillator plate 1 and a shell. The defibrillator plate 1 is used to contact human skin. The shell is set as a hollow structure with a chamber inside. The shell is set on one side of the defibrillator plate 1 and is fixed to the defibrillator plate 1. Among them, the pre-stressing component is set inside the shell, and the above-mentioned accommodating chamber is formed between the pre-stressing component and the defibrillator plate 1, that is, the accommodating chamber is located inside the shell and is arranged close to the defibrillator plate 1. Through the deformation or displacement of the pre-stressing component relative to the shell, the volume of the accommodating chamber changes, and then the pre-stressing component compresses the accommodating chamber to form a pre-tightening force. The glue outlet 11 of the accommodating chamber is set on the defibrillator plate 1, and a glue outlet channel is opened on the shell, and the internal chamber of the shell is connected to the glue outlet 11 through the glue outlet channel. In this way, by setting the shell, the pre-stressing component and the accommodating chamber can be protected, and the stability of the storage and release of the conductive gel 4 can be improved.

[0042] The outer shell is provided with a glue loading port 12, which is provided on a side of the outer shell close to the defibrillator plate 1. The glue loading port 12 is the glue outlet channel mentioned above. By designing the size of the glue loading port 12, the elastic capsule 5 in the expanded state can be loaded through the glue loading port 12. Moreover, the glue outlet 11 on the defibrillator plate 1 can limit the passage of the elastic capsule 5. During use, when the outer shell and the defibrillator plate 1 are separated, the elastic capsule 5 can be loaded and unloaded through the glue loading port 12 to achieve the replacement of the elastic capsule 5. When the outer shell and the defibrillator plate 1 are assembled together, the elastic capsule 5 in the expanded state can be limited to keep the elastic capsule 5 in the accommodating cavity. In this way, the installation process is simple and reliable, which is conducive to the replacement of the elastic capsule 5 and further realizes multiple reuse.

[0043] Specifically, the defibrillator paddle 1 and the housing may be detachably connected by snapping or gluing, which is not specifically limited here.

[0044] The glue outlet 11 is configured as a microporous structure, and the glue outlet 11 includes a plurality of small holes, which penetrate the defibrillator plate 1 and are distributed in an array to form a glue outlet area on the defibrillator plate 1 for the conductive gel 4 to pass through, which is conducive to improving the uniformity of glue outlet. Moreover, since the size of the small hole is smaller than the size of the elastic capsule 5, the glue outlet 11 can limit the passage of the elastic capsule 5 to limit the elastic capsule 5 in the accommodating cavity. The "microporous structure" mentioned here does not limit the size of the hole, and the size of the hole only needs to prevent the elastic capsule from passing through.

[0045] It should be noted that the positions of the glue outlet 11 and the glue filling port 12 are aligned, the size of the glue outlet 11 is smaller than the size of the glue filling port 12, the glue outlet 11 corresponds to the middle area of ​​the glue filling port 12, and the glue filling port 12 corresponds to the middle area of ​​the accommodating cavity, so as to facilitate the discharge of the conductive gel 4.

[0046] In this solution, the pre-stressing component is set as an elastic diaphragm 10, and the edge position of the elastic diaphragm 10 is sealed and connected to the inner wall of the shell. The elastic diaphragm 10 can divide the interior of the shell into two chambers, one of which is close to the defibrillator plate 1 and forms a receiving chamber. Since the elastic diaphragm 10 has high elasticity, when the elastic capsule 5 is loaded into the receiving chamber, the elastic diaphragm 10 is squeezed to deform in the direction away from the defibrillator plate 1. At this time, the elastic diaphragm 10 has elastic potential energy in the direction close to the defibrillator plate 1, and the elastic potential energy is applied to the elastic capsule 5 located in the receiving chamber, that is, the pre-tightening force applied to the receiving chamber by the pre-stressing component is formed. In this way, the pre-stressing component adopts the form of an elastic diaphragm 10, which can save the internal space of the shell, improve the reliability of the structure, and facilitate the sealing of the receiving chamber.

[0047] Of course, in other solutions, the preload component can also be configured in other forms, for example, it can be configured as a piston and a spring in the housing, and the above-mentioned preload force can be formed by the spring driving the piston.

[0048] The housing includes a base 2 and a cover 9. The base 2 is attached to one side of the defibrillator plate 1, and the cover 9 is buckled on the side of the base 2 away from the defibrillator plate 1. The edge of the elastic diaphragm 10 is pressed between the base 2 and the cover 9. In this way, the elastic diaphragm 10 is sealed and connected by the connection between the cover 9 and the base 2, which has good sealing and connection reliability. In combination, the glue filling port 12 is set on the base 2, and the cover 9 surrounds the outer periphery of the glue outlet 11.

[0049] Among them, the seat body 2 is provided with an annular protrusion 13, which is located on the side of the seat body 2 away from the defibrillator plate 1, and the inner wall of the cover body 9 abuts against the outer wall of the annular protrusion 13 to clamp the edge of the elastic diaphragm 10 between the cover body 9 and the annular protrusion 13, further improving the connection reliability and sealing. In addition, the provision of the annular protrusion 13 can form a gap between the middle part of the elastic diaphragm 10 and the main part of the seat body 2, and the gap is the inner area of ​​the annular protrusion 13, and the distance of the gap is the protrusion height of the annular protrusion 13, which is conducive to the elastic bag 5 being loaded into the accommodating cavity.

[0050] Specifically, the edge of the elastic diaphragm 10 is set as a thickened portion 14. When the edge position of the elastic diaphragm 10 is clamped between the cover body 9 and the seat body 2, the thickened portion 14 is outside the cavity formed by the cover body 9 and the seat body 2, and the middle area of ​​the elastic diaphragm 10 is inside the cavity formed by the cover body 9 and the seat body 2. In this way, the design of the thickened portion 14 can prevent the elastic diaphragm 10 from slipping.

[0051] In the present embodiment, the puncturing assembly is arranged on the outside of the accommodating cavity, that is, on the outside of the cavity surrounded by the cover body 9 and the base body 2. The puncturing assembly includes a driving member 7 and a puncturing member 8. The driving member 7 is used to output a driving action. The puncturing member 8 is transmission-connected to the driving member 7 so that when the driving member 7 outputs a driving action, it can drive the puncturing member 8 to extend into the accommodating cavity and puncture the elastic bag 5 located in the accommodating cavity.

[0052] Specifically, the driving member 7 is configured as a linear motor having a driving shaft, the piercing member 8 is configured as a pointed structure and connected to the driving shaft, the linear motor outputs a linear motion and drives the piercing member 8 to move linearly, so that the piercing member 8 extends into the accommodating cavity along a straight line. Of course, the driving member 7 can also be configured with other structures, such as a rotary motor and a lead screw nut structure.

[0053] In combination with the above-mentioned scheme of the elastic membrane 10, a first hole portion is provided on the cover body 9, a second hole portion is provided on the elastic membrane 10, and a third hole portion is provided on the annular protrusion 13. The first hole portion, the second hole portion and the third hole portion are aligned to form a passage hole 3 for the piercing member 8 to pass through. The path of the piercing member 8 driven by the driving member 7 to move, the extension direction of the piercing member 8 and the axial direction of the passage hole 3 are on the same straight line, so that the housing, the elastic membrane 10 and the annular protrusion 13 form a avoidance for the piercing member 8, which is conducive to piercing the elastic bag 5. Moreover, the passage hole 3 passes through the annular protrusion 13, and when the elastic membrane 10 recovers its deformation, it will not collide with the piercing member 8, so that the piercing member 8 will not cause damage to the elastic membrane 10, which is conducive to repeated use.

[0054] In order to prevent the conductive gel 4 in the accommodating cavity from leaking from the passage hole 3, the piercing member 8 includes a pointed portion and a plate-shaped portion. The plate-shaped portion is perpendicular to the axial direction of the passage hole 3, the pointed portion is arranged on the plate-shaped portion, and the plate-shaped portion is arranged on the driving shaft of the driving member 7. Under the driving action of the driving member 7, the pointed portion penetrates the passage hole 3, and when piercing the elastic bag 5 in the accommodating cavity, the plate-shaped portion abuts against the end face of the passage hole 3 to form a blockage for the passage hole 3.

[0055] The base 2 is provided with a box 6, and the driving member 7 and the piercing member 8 are both provided in the box 6. The box 6 can protect the driving member 7 and the piercing member 8, thereby improving the stability of the piercing function. Specifically, the inner wall of the cover 9 abuts against the outer wall of the annular protrusion 13, and a part of the outer wall of the cover 9 abuts against a part of the outer wall of the box 6, so that the cover 9 abuts between the annular protrusion 13 and the box 6, and a fourth hole portion is provided on the box 6, which is aligned with the first hole portion and constitutes a part of the passage hole 3, so that the piercing member 8 can penetrate the box 6 and enter the accommodating cavity.

[0056] In other embodiments, the puncture assembly is disposed inside the accommodating cavity, specifically inside the annular protrusion 13, or between the elastic capsule 5 and the elastic diaphragm 10. The puncture assembly includes a main body and a puncture member 8, which can be hidden in the main body and can be controllably protruded from the main body. By adjusting the installation position of the puncture assembly, the puncture member 8 can be protruded toward the elastic capsule 5 to puncture the elastic capsule 5. In this way, the puncture assembly is built into the accommodating cavity, which can save the space occupied by the puncture assembly.

[0057] The conductive gel release mechanism is described in detail below in conjunction with the above embodiments.

[0058] like Figure 1 As shown, the conductive gel release mechanism leads out two wires for driving the glue spraying, which can control the linear motor (driving element 6). When the linear motor is energized, its output shaft can be driven to extend outward, and the motor output shaft is connected to the sharp needle (piercing element 8), thereby pushing the sharp needle to move. The outer shell is a hard protective shell. After the defibrillator device is worn on the body, the outer shell bears pressure and external force to protect its internal structure from being squeezed. The outer shell includes a cover body 9 and a seat body 2, and an elastic diaphragm 10 is arranged between the two. The outer circumference of the elastic diaphragm 10 is clamped between the cover body 9 and the seat body 2. The outer shell also includes a box body 6 arranged on the seat body 2, in which a linear motor and a sharp needle are installed, and a fourth hole portion is arranged on the box body 6 for the sharp needle to pass through. The elastic capsule 5 forms a sealed cavity, in which the conductive gel 4 is filled. The elastic diaphragm 10 and the elastic capsule 5 are both materials with high elastic tensile strength and high elastic pressure. Figure 1 The configuration structures shown are all in a state of high stretch and high elastic force. The defibrillator paddle 1 is the end of the electrode that releases energy to the skin. The defibrillator paddle 1 is bonded to the shell by double-sided adhesive. The defibrillator paddle 1 is provided with a glue outlet 11, which is directly opposite to the glue loading port 12 on the seat 2. The elastic capsule 5 and the conductive gel 4 inside it are pressed against the glue outlet 11. The passage hole 3 is a hole through which the sharp needle extends. The passage hole 3 is reserved. The box body 6, the cover body 9, the elastic diaphragm 10 and the annular protrusion 13 are all reserved with holes for forming the passage hole 3 to form the passage hole 3.

[0059] like Figure 2As shown, when the patient needs defibrillation and needs to spray glue, the motor output line is energized to control the linear motor output axial movement, thereby pushing the sharp needle to move toward the accommodating cavity, and the sharp needle passes through the aisle hole 3, thereby puncturing the elastic capsule 5 (the material properties of the elastic capsule 5 are more easily punctured when it is stretched at a high stretch amount and stretched at a high elastic force). After the elastic capsule 5 is punctured, the conductive gel 4 inside it is squeezed and released, and at the same time, the elastic diaphragm 10 squeezes the elastic capsule 5, so that the conductive gel 4 penetrates the defibrillator plate 1 from the glue outlet 11 and is released to the skin surface. Among them, after the elastic capsule 5 releases the conductive gel 4, due to its large elastic deformation, it will shrink to a very small volume, and the volume after shrinkage will be smaller than the distance between the elastic diaphragm 10 and the seat body 2 to avoid blockage.

[0060] like Figure 3 As shown, during the installation process of the release structure of the conductive gel 4, the linear motor and the sharp needle are first installed into the box body 6, and then the elastic membrane 10 is clamped between the cover body 9 and the base body 2, and the elastic membrane 10 is in a relaxed and flat state. The elastic capsule 5 is filled with the conductive gel 4, and it is ensured that the elastic capsule 5 is in an open state of being stretched and stretched by the internal conductive gel 4 with high tensile strength and high elasticity after being filled, and the elastic capsule 5 filled with the conductive gel 4 is inserted into the accommodating cavity formed between the elastic membrane 10 and the base body 2 through the glue loading port 12 on the base body 2, so that the elastic membrane 10 will also be stretched and in a state of being stretched by high tensile strength and being stretched by high elasticity. Finally, the defibrillator plate 1 is attached to the base body 2, and the elastic capsule 5 and the elastic membrane 10 are blocked in the cavity formed by the cover body 9 and the base body 2 through the defibrillator plate 1. The glue outlet 11 can be opened into a small hole, or multiple small holes, so that the elastic capsule 5 will not be squeezed out from the glue outlet.

[0061] The embodiment of the present application provides a wearable defibrillator device, including the conductive gel release mechanism in the above embodiment, and also including a defibrillator host, defibrillator electrodes (defibrillator pads 1) and induction electrodes, wherein the defibrillator electrodes and induction electrodes are arranged on a vest and in contact with the skin of a human body, and the conductive gel release mechanism, the defibrillator electrodes and the induction electrodes are connected to the defibrillator host through cables. In the detection stage, the defibrillator host contacts the patient's chest through the induction electrodes and the defibrillator electrodes, detects the electrical activity of the heart, analyzes the electrocardiogram waveform, and determines whether there is a serious arrhythmia. If ventricular fibrillation or ventricular flutter, etc., which require defibrillation, enters the defibrillation stage. During the defibrillation stage, the defibrillator host sends a signal to the conductive gel release mechanism to control the drive member to drive the puncture member to move until the puncture member punctures the elastic capsule. The conductive gel in the elastic capsule loses the wrapping effect of the elastic capsule and diffuses into the accommodating cavity, while breaking the pressure balance in the accommodating cavity, causing the accommodating cavity to lose the holding force of the elastic capsule. Then the pre-pressure component drives the accommodating cavity to begin to contract, and the conductive gel in the accommodating cavity is discharged from the gel outlet to between the defibrillator electrode and the human skin. The defibrillator host sends defibrillation energy to the defibrillator electrode, and the defibrillator electrode transmits current to the heart to reset the heart's electrical activity and restore the heart to normal rhythm.

[0062] With such arrangement, by puncturing the elastic capsule 5 in the accommodating cavity, the conductive gel 4 in the elastic capsule 5 can flow out from the gel outlet 11 under the action of the pre-pressing component, without the involvement of an air pressure source, with a simple structure and low cost.

[0063] Among them, Figure 4 As shown, there are multiple conductive gel release mechanisms, that is, a defibrillator paddle 1 is correspondingly provided with multiple shells (i.e., a base body, a cover body and a box body), and then the conductive gel 4 is released through multiple glue outlets 11 to improve the uniformity of the conductive gel 4 applied between the defibrillator paddle 1 and the human skin.
