Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an anti-accidental activation switch for wearable defibrillators and a defibrillator. Background Technology

[0002] Wearable defibrillators (WCDs) are devices that can be worn on a patient's body with the defibrillator unit and electrodes. They do not require external assistance and can automatically monitor the patient's electrocardiogram signals in real time. If a life-threatening heart rhythm signal is detected, the device will automatically deliver an electric shock to defibrillate the heart and restore its normal function.

[0003] Currently, in order to reduce the occurrence of false shocks, WCDs usually warn patients before defibrillation and are equipped with a patient response switch. The patient can operate the switch to cancel the shock before the WCD delivers a false shock, thereby reducing the occurrence of false shocks.

[0004] While existing patient response switches for wired defibrillators (WCDs) allow patients to easily cancel shocks, several issues arise during use. First, these switches are push-button switches located on the surface of the WCD casing. Since the WCD is worn continuously, a patient collapsing during cardiac arrest could accidentally activate the switch, canceling defibrillation and rendering the WCD ineffective. Second, the front-mounted switches require the patient to locate them before operating them after a false shock warning. This cumbersome design, especially from a top-down view, complicates the process and increases the risk of false shocks. Utility Model Content

[0005] To address the aforementioned deficiencies, the technical problem to be solved by this utility model is to provide an anti-accidental activation switch for wearable defibrillators and a defibrillator. This anti-accidental activation switch can prevent patients from accidentally activating the defibrillator switch when they fall to the ground, thus avoiding erroneous cancellation of defibrillation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] In a first aspect, a switch for preventing accidental activation in a wearable defibrillator is provided, comprising:

[0008] A housing support is disposed within a mounting port on the main body shell of the wearable defibrillator, and the housing support is provided with a first mounting groove;

[0009] A sliding switch is disposed in a first mounting slot. The sliding switch has a sliding lever and is configured to slide to a preset position via the lever to cancel the defibrillator's defibrillation.

[0010] A transmission bracket, which is movably connected within a first mounting slot;

[0011] A cover body, which is fixedly connected to the housing support, closes the mounting opening, and has mounting holes;

[0012] A paddle is slidably mounted in a mounting hole and connected to the lever via the transmission bracket.

[0013] By adopting the above scheme, during use, the lever moves the transmission bracket, which in turn moves the lever to a preset position to remove the defibrillator's electric shock. Since the sliding switch can only remove the defibrillator's electric shock when the lever is slid to the preset position, even if a patient experiences cardiac arrest and collapses, squeezing the lever and sliding switch, the sliding switch will not move to the preset position to remove the defibrillator's electric shock. This ensures the defibrillator can deliver the shock normally and effectively avoids accidental cancellation of the defibrillator due to accidental activation of the deactivation switch.

[0014] Preferably, the mounting port is located on the top of the main unit casing. Because the mounting port is on the top of the main unit casing, the user can easily see the switch by looking down, making it easier for the user to observe and use.

[0015] Preferably, the paddle has a protrusion on the side away from the transmission bracket, and the free end of the protrusion extends outside the mounting hole. The protrusion extending outside the mounting hole makes it convenient for the user to operate the paddle.

[0016] Preferably, an elastic element is provided between the transmission bracket and the first mounting slot. This elastic element is configured to reset the transmission bracket and the lever after the defibrillator is deactivated by sliding the lever to a preset position. Because the first elastic element can reset the transmission bracket and the lever after the defibrillator is deactivated by sliding the lever to the preset position, it prevents the user from forgetting to reset the lever. Furthermore, if the lever is accidentally moved to the preset position, the elastic element can reset the lever, further reducing the probability of accidents.

[0017] Preferably, the elastic element is a spring. A first boss is provided on one side of the transmission bracket, and a second mounting groove corresponding to the first boss is provided in the first mounting groove. One end of the spring is sleeved on the first boss, and the other end abuts against the second mounting groove. Because the first boss and the second mounting groove of the transmission bracket constrain both ends of the spring, the stability of the spring is further improved, thereby further enhancing the stability of the spring.

[0018] Preferably, the transmission bracket has a first protrusion and a second protrusion on both sides, the first protrusion having a first receiving groove and the second protrusion having a second receiving groove, the lever having a second boss, the second boss being inserted into the first receiving groove, and the lever being inserted into the second receiving groove. The engagement of the second boss with the first receiving groove and the lever with the second receiving groove facilitates easier assembly between the transmission bracket, the lever, and the slide switch.

[0019] Preferably, a switch cover is provided between the paddle and the transmission bracket. The switch cover is fixedly connected to the housing bracket and covers the openings of the first and second mounting slots. The switch cover has a first clearance hole for the first protrusion to move. The switch cover can confine the transmission bracket within the first mounting slot, preventing it from detaching. Furthermore, the switch cover can cover the top openings of the first and second mounting slots, separating the transmission bracket and the sliding switch within the first mounting slot from the external space, thus enhancing the protection of the sliding switch.

[0020] Preferably, the switch cover is provided with a guide groove, and the paddle is provided with a guide portion that matches the guide groove, the guide portion being slidably connected within the guide groove. The paddle's sliding stability is improved by the cooperation between the guide portion and the guide groove on the switch cover, and support is provided for the paddle. When the paddle is externally pressed, it remains stable, further enhancing its stability.

[0021] Preferably, a gasket is provided on the lower side of the switch cover, and the gasket has a second clearance hole corresponding to the first clearance hole. A pad is provided between the gasket and the transmission bracket, and the pad has a through hole. The first protrusion passes through the through hole, and the pad and the gasket are in slidable contact. The sliding contact between the gasket and the pad improves the sealing performance at the first clearance hole, enhances the waterproof effect, and thus improves the isolation effect on the transmission bracket and the sliding switch inside the first mounting groove.

[0022] Secondly, this utility model also provides a defibrillator, including the aforementioned anti-accidental activation switch for wearable defibrillators.

[0023] In summary, the anti-accidental activation switch and defibrillator for wearable defibrillators provided by this utility model have at least the following beneficial effects:

[0024] 1. Since the slide switch can only remove the defibrillator's electric shock by moving the lever to the preset position, it can prevent the user of the wearable defibrillator from accidentally touching the switch when falling to the ground, thus removing the defibrillator's electric shock.

[0025] 2. Improved the convenience for users to find the switch, further reducing the difficulty for users to find the switch.

[0026] 3. The sliding contact between the gasket and the pad improves the sealing performance at the first clearance hole, enhances the waterproofing effect, and improves the reliability of the switch. Attached image description:

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-8 The present invention will be further described in detail below with reference to specific embodiments.

[0038] Please see Figure 1-7 This embodiment provides an anti-accidental activation switch for a wearable defibrillator, comprising: a housing bracket 1, a sliding switch 2, a transmission bracket 4, a cover 5, and a lever 7. The housing bracket 1 is disposed within a mounting opening on the main housing 29 of the wearable defibrillator, and the housing bracket 1 is detachably connected to the mounting opening, which is located on the top of the main housing 29. The housing bracket 1 has a first mounting groove 8, and the sliding switch 2 is disposed within the first mounting groove 8. The sliding switch 2 is connected to the housing bracket 1 via a fastening bolt 9. The sliding switch 2 is a prior art device, and it has a lever 3 capable of horizontal sliding. The lever 3 is specifically located on the upper side of the sliding switch 2, and the sliding switch 2 is configured to slide to a preset position via the lever 3 to remove the defibrillator's electric shock. The transmission bracket 4 is movably connected within the first mounting groove 8, and the cover 5 is fixedly connected to the upper side of the housing bracket 1, closing the mounting opening on the main housing 29. The cover 5 has a mounting hole 6, which is a strip-shaped hole. The paddle 7 is slidably installed in the mounting hole 6 and is connected to the lever 3 via a transmission bracket 4. The paddle 7 has outwardly extending flanges 10 on all four sides, located on the underside of the cover 5. During the sliding process of the paddle 7 within the mounting hole 6, the flanges 10 are confined to the inside of the cover 5, preventing the paddle 7 from detaching from the mounting hole 6.

[0039] An elastic element 11 is provided between the transmission bracket 4 and the first mounting groove 8. The elastic element 11 is configured to drive the transmission bracket 4 and the lever 3 to reset after the defibrillator is removed by sliding to a preset position via the lever 3.

[0040] The paddle 7 has a protrusion 12 on the side away from the transmission bracket 4, that is, the upper side of the paddle 7 has a protrusion 12, and the free end of the protrusion 12 extends out of the mounting hole 6. The protrusion 12 allows the user to easily move the paddle 7 to a preset position, making it convenient for the user to operate.

[0041] The upper center of the cover 5 is recessed downward to form a recess 13, and the mounting hole 6 is located within the recess 13. The recess 13 reduces the height of the protrusion 12 of the paddle 7 protruding from the top edge of the cover 5, thereby reducing the risk of accidental operation of the paddle 7. Furthermore, the height of the protrusion 12 protruding from the surface of the recess 13 is sufficient for the user to operate.

[0042] The elastic element 11 is a spring. A first boss 14 is provided on the left side of the transmission bracket 4, and a second mounting groove 15 corresponding to the first boss 14 is provided in the first mounting groove 8. The second mounting groove 15 is specifically located on the left side of the first mounting groove 8, and the right and upper sides of the second mounting groove 15 are open. The right end of the spring is sleeved on the first boss 14 and abuts against the transmission bracket 4; the left end of the spring is located in the second mounting groove 15 and abuts against the second mounting groove 15.

[0043] The transmission bracket 4 has a first protrusion 17 and a second protrusion 18 on its upper and lower sides, respectively. The first protrusion 17 is specifically located on the upper side of the transmission bracket 4, and the second protrusion 18 is specifically located on the lower side of the transmission bracket 4. The first protrusion 17 has a first receiving groove 19, and the second protrusion 18 has a second receiving groove 20. The lever 7 has a second boss 16, which is specifically located on the lower side of the lever 7. The second boss 16 is inserted into the first receiving groove 19, and the lever 3 is inserted into the second receiving groove 20.

[0044] A switch cover 21 is provided between the paddle 7 and the transmission bracket 4. The switch cover 21 is fixedly connected to the housing bracket 1. The switch cover 21 covers the openings at the top of the first mounting groove 8 and the second mounting groove 15. The openings of the first mounting groove 8 and the second mounting groove 15 are both located on the upper side. The switch cover 21 is provided with a first clearance hole 26 for the first protrusion 17 to move.

[0045] Please see Figure 5 and Figure 6 The switch cover 21 is provided with guide grooves 22, specifically two guide grooves 22 arranged in parallel. The lever 7 is provided with guide portions 23 that match the guide grooves 22, specifically located at the front and rear ends of the flange 10 and protruding downwards. The two guide portions 23 are arranged one-to-one with the two guide grooves 22, and are slidably connected within their respective guide grooves 22.

[0046] A gasket 24 is provided on the lower side of the switch cover 21, and a second clearance hole 27 corresponding to the first clearance hole 26 is provided on the gasket 24. A pad 25 is provided between the gasket 24 and the transmission bracket 4, and a through hole 28 is opened on the pad 25. The first protrusion 17 passes through the through hole 28, and the pad 25 and the gasket 24 can slide in contact. The gasket 24 can be elastic or non-elastic, with a smooth surface and high flatness; the pad 25 is elastic. The pad 25 and the gasket 24 abut against each other. When the pad 25 and the gasket 24 slide relative to each other, the elasticity of the pad 25 can maintain a tight contact between the pad 25 and the gasket 24, achieving a waterproof effect.

[0047] By adopting the above scheme, in the initial state, the lever 3 of the sliding switch 2 is in the initial position. During use, the lever 7 drives the transmission bracket 4 to move, and the transmission bracket 4 drives the lever 3 to slide to the preset position to remove the defibrillator's electric shock. When the user releases the lever, the lever 3 of the sliding switch 2 returns to the initial position under the elastic force of the elastic element 11. Since the sliding switch 2 can only remove the defibrillator's electric shock by sliding the lever 3 to the preset position, even if the patient experiences cardiac arrest and falls to the ground, the pressure on the lever 7 and the sliding switch 2 will not cause the lever 3 of the sliding switch 2 to move to the preset position to remove the defibrillator's electric shock. This ensures that the defibrillator can deliver the electric shock normally and effectively avoids the situation where accidental activation of the defibrillator leads to incorrect cancellation of the electric shock.

[0048] Please see Figure 7 and Figure 8 Based on the same inventive concept, this utility model also provides a defibrillator, including the aforementioned anti-accidental activation switch for a wearable defibrillator. The defibrillator specifically includes: a main unit, a main unit housing 29, ECG electrodes, and defibrillation electrodes. The anti-accidental activation switch is located on the top of the main unit housing 29. The ECG electrodes and defibrillation electrodes are both mounted on a vest 30 and are electrically connected to the main unit. The main unit is detachably installed in a carrying case 31 and can be worn by the user, moving with the body. The control unit in the main unit can control the acquisition and recognition of ECG information. After identifying specific abnormal ECG information through the ECG electrodes, defibrillation shock energy can be output to the body through the defibrillation electrodes.
