Description

Technical Field

[0001] The present invention relates to the technical field of cardiac pacing, and particularly to a wearable cardiac pacing device. Background Art

[0002] For some patients suffering from severe heart diseases, myocardial lesions or other irreversible heart diseases, they may need to rely on a pacemaker for a long time to maintain a normal heart rhythm. At this time, a wearable cardiac pacemaker can be used as a long-term adjuvant treatment means to help patients stabilize their conditions and extend their survival time.

[0003] When a wearable cardiac pacing device is worn, the electrode patch is attached to the position of the heart on the chest cavity. When an abnormal heart rhythm is detected, the pacemaker will automatically deliver electrical pulses according to preset parameters, stimulating specific parts of the heart, so that the heart contracts and relaxes according to the normal heart rhythm, thereby correcting the abnormal heart rhythm.

[0004] The electrode patches of existing wearable cardiac pacing devices are fixed to the chest cavity by means of tape. However, the tape is often adhered for a long time, which easily causes itching and red rashes on the skin, making the patient feel uncomfortable. If the patient scratches subconsciously, it may cause the electrode patch to shift, so that the pulse of the electrode patch cannot be accurately applied to the designated position of the heart, which will affect the normal use of the pacing device.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Next, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included. Embodiment

[0032] Referring to Figures 1-8 , which is the first embodiment of the present invention. This embodiment provides a wearable cardiac pacing device, including a wearable vest 1. The wearable vest 1 is provided with a front covering 11. The wearable vest 1 is connected with a control module 12. The front covering 11 is provided with electrode patches 14, and the electrode patches 14 are electrically connected to the control module 12. The fitting surface of the front covering 11 is provided with multiple groups of pressing bladders 2. The interior of the front covering 11 is provided with a chamber 21, and a through hole 22 is provided between the pressing bladder 2 and the chamber 21. A breathing valve 23 is installed on the outer wall of the front covering 11. The breathing valve 23 and the chamber 21 have a communication channel. A hose 25 is provided on the inner wall of the chamber 21. One end of the hose 25 extends out of the outside of the front covering 11. One end of the hose 25 is installed with a hollow column 26. The end of the hollow column 26 is fixedly connected to the electrode patch 14. An air outlet hole 27 is provided on the outer wall of the hollow column 26. A fixing patch 4 is provided around the electrode patch 14. The wearable vest 1 is strapped tightly on the patient, and multiple groups of pressing bladders 2 are distributed at the easily fluctuating parts of the human body, namely the abdomen and one side of the shoulder. The normal breathing fluctuations of the abdomen squeeze some of the pressing bladders 2, and when walking, the starting of the shoulder will press another part of the pressing bladders 2. When the pressing bladder 2 is squeezed, the gas in the bladder enters the interior of the chamber 21 through the through hole 22. The gas in the chamber 21 then enters the interior of the hollow column 26 through the hose 25, and finally the gas diffuses from the periphery of the electrode patch 14 to the outside of the fixing patch 4, improving the air permeability at the fixing patch 4.

[0033] Specifically, the electrode patch 14 is connected to the front covering 11 through a wire, and both the wire and the hose 25 have telescopic redundancy, so that the wire and the hose 25 will not be pulled when the electrode patch 14 is attached.

[0034] Furthermore, a ring 231 is provided on the inner wall of the breathing valve 23. A baffle 232 is installed on the outer wall of the ring 231, and the convex edge area of the baffle 232 is adhered on the side of the ring 231 close to the chamber 21. When the pressing bladder 2 is restored, the interior of the chamber 21 is in negative pressure, so that the baffle 232 naturally inclines due to the negative pressure to open the opening of the ring 231, enabling the outside gas to supplement and enter the interior of the chamber 21 through the breathing valve 23.

[0035] Furthermore, a fixing ring 3 is installed on the outer wall of the hollow column 26, and an embedding groove 31 is opened on the side of the fixing ring 3 facing the electrode sheet 14. The inner wall of the embedding groove 31 is connected with two groups of protruding arc strips 32 through a sliding member, and a pressure-bearing inclined block 33 is installed on the outer arc surface of the protruding arc strip 32. The outer ring of the fixing ring 3 is provided with a slidingly connected rotating contact block 34, and the inner arc surface of the rotating contact block 34 is provided with a contact pressure convex block 35, and the contact pressure convex block 35 is located on one side of the pressure-bearing inclined block 33. Two groups of sealing sheets 36 with different ring diameters are provided on both sides of the notch of the embedding groove 31, and the plastic ring 42 of the fixing patch 4 is inserted into the fixing patch 4. The fixing ring 3 is embedded in the groove 31. At this time, the groove 43 is located on one side of the protruding arc strip 32. At this time, the rotating contact block 34 is moved manually. The rotating contact block 34 rotates to drive the contact and pressure protrusion 35 to rotate. The rotational movement of the contact and pressure protrusion 35 passes through the pressure-bearing inclined block 33, so that the pressure-bearing inclined block 33 is touched downward by the passing contact and pressure protrusion 35, and then the protruding arc strip 32 is embedded in the groove 43, so that the plastic ring 42 is locked on the fixing ring 3. At this time, the sealing sheet 36 of the fixing ring 3 contacts the surface of the fixing patch 4, so that the connection between the fixing ring 3 and the plastic ring 42 is sealed.

[0036] Furthermore, the two groups of protruding arc strips 32 are arranged through an axial mirror image, and the rotating contact block 34 is artificially rotated to slide the contact and pressure protrusion 35 along the pressure-bearing inclined block 33, so that the protruding arc strip 32 protrudes in the embedded groove 31, and the inclined surface of the pressure-bearing inclined block 33 is set according to the rotation direction of the rotating contact block 34, so that the rotating contact block 34 can contact and press the protruding arc strip 32 when rotating, and the terminal end of the inclined surface is an arc surface with a constant diameter at one end, so that the rotating and moving contact and pressure protrusion 35 can remain stable on the arc surface, thereby preventing the protruding arc strip 32 from recovering and moving back.

[0037] Furthermore, the adhesive surface of the fixing patch 4 is provided with a breathable and flow-guiding pattern 41 , and the central area of the fixing patch 4 is a hollow ring, so that the fixing patch 4 can penetrate to the other side of the electrode sheet 14 .

[0038] Furthermore, a plastic ring 42 is provided on the non-adhesive surface of the fixed patch 4, and a groove 43 is provided on the outer ring of the plastic ring 42. The size of the plastic ring 42 matches the size of the embedding groove 31, so that the plastic ring 42 can be inserted into the embedding groove 31, and the protruding arc strip 32 in the embedding groove 31 can match the groove 43 of the plastic ring 42 after movement.

[0039] Furthermore, a filling block 5 is connected to the inside of the hollow column 26 , and the filling block 5 is connected to one side of the hose 25 , so that when the gas in the hose 25 enters the hollow column 26 , the gas first passes through the filling block 5 .

[0040] Furthermore, an injection channel 51 is installed on the outer wall of the filling block 5, one end of the injection channel 51 extends out of the outer wall of the hollow column 26, and an air outlet hole 52 is provided at the end of the filling block 5. The air outlet hole 52 connects the internal cavity of the filling block 5 with the internal cavity of the hollow column 26, and the gas first enters the filling block 5, and the filling block 5 can be filled with ointments such as mint cream that can relieve skin pressure through the injection channel 51. The flowing gas can drive the mint gas to flow out from the air outlet hole 52 and finally be slowly exhaled from the air outlet 27 of the hollow column 26. The mint component can bring a cooling feeling to the skin, thereby relieving itching to a certain extent.

[0041] Operation process: When wearing, put the new fixed patch 4 on one side of the electrode sheet 14, insert the plastic ring 42 of the fixed patch 4 into the embedding groove 31 of the fixed ring 3, and the groove 43 is located on the side of the protruding arc strip 32. Then move the rotating contact block 34 manually, and the rotating contact block 34 drives the contact and pressure protrusion 35 to rotate. The rotation of the contact and pressure protrusion 35 passes through the pressure inclined block 33, so that the pressure inclined block 33 is touched downward by the contact and pressure protrusion 35 passing by, so that the protruding arc strip 32 is embedded in the groove The inside of 43 makes the plastic ring 42 locked on the fixing ring 3. At this time, the sealing sheet 36 of the fixing ring 3 contacts the surface of the fixing patch 4, so that the connection between the fixing ring 3 and the plastic ring 42 is sealed. At this time, the protective layer of the adhesive surface of the fixing patch 4 can be torn off, and the fixed position can be accurately found for pasting. At this time, the wearing vest 1 is tied tightly on the patient, and the multiple groups of pressing capsules 2 are distributed on the parts of the human body that are prone to fluctuations, that is, the abdomen and one side of the shoulder. The normal breathing fluctuation of the abdomen squeezes part of the pressing capsule 2, and when walking, The starting of the shoulder will touch the other part of the pressing capsule 2. When the pressing capsule 2 is squeezed, the gas in the capsule enters the chamber 21 through the through hole 22. The gas in the chamber 21 enters the hollow cavity through the hose 25. The gas first enters the filling block 5, and the filling block 5 can be filled with ointment such as mint cream that can relieve skin pressure through the injection channel 51. The flowing gas can drive the mint gas to flow out from the outlet hole 52, and finally slowly spit out from the exhalation hole 27 of the hollow column 26. The exhaled gas is exhaled from the four sides of the electrode sheet 14 and gradually diffuses to the four sides for ventilation. The breathable guide pattern 41 of the fixed patch 4 achieves better ventilation, effectively alleviating the pressure on the skin caused by the adhesive fixing part, and improving the wearing comfort of the electrode sheet 14. When the pressing capsule 2 is not pressed, the pressing capsule 2 relies on the elasticity of its own rubber material to recover, and the breathing valve 23 replenishes the outside gas into the interior of the chamber 21, so that the exhaled gas around the electrode sheet 14 can be reciprocated.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
