Description

[0002] Diaphragm pacing improves ventilation by causing diaphragm contraction through functional electrical stimulation of the phrenic nerve. It is divided into two types: implantable diaphragm pacemakers and external diaphragm pacemakers. The former is traumatic and can lead to many iatrogenic complications, which are difficult for patients to accept. It is also expensive and not suitable for rehabilitation treatment. Therefore, external diaphragm pacemakers are often used as a convenient medical device in clinical practice to treat patients.

[0003] An external diaphragmatic pacemaker is a medical device that electrically stimulates the phrenic nerve and enhances the diaphragm's contraction ability. Diaphragm contraction is stimulated by attaching electrodes to the patient's body surface. How to fix the electrodes has become a common problem in clinical use. Currently, fixing devices using adhesives, suction cups, negative pressure adsorption, etc. can initially fix the electrodes. However, for different stimulation positions of different patients, such as the costal arch surface, the existing fixing devices cannot effectively fit the patient's skin surface, and the risk of the electrodes falling off is relatively high.

[0004] Therefore, those skilled in the art need a pacemaker device that can fully fit the patient's skin and has good working performance to overcome the above problems. Summary of the Invention

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0043] refer to Figures 1-6 According to an embodiment of the present invention, an external diaphragm pacemaker device includes a controller, a connecting wire, an electrode 1, a fixing device 2 and an adjustment component 3. The fixing device 2 is provided with a wiring hole, and the connecting wire is connected between the controller and the wiring hole. The electrode 1 is snapped into the fixing device 2 and electrically connected to the connecting wire. When in use, the electrode 1 is first installed in the fixing device 2, and the fixing device 2 is attached to the patient's diaphragm, and the controller and the fixing device 2 are kept connected through the connecting wire. Medical staff can adjust the intensity and frequency of the electrode 1 stimulating the patient's diaphragm contraction by operating the controller, thereby achieving the effect of improving the patient's breathing.

[0044] The adjusting component 3 is provided on the fixing device 2 and is suitable for adjusting the curvature of the fixing device 2 according to the curvature of the electrode sheet 1. The fixing device 2 can be connected to the patient's skin using an installation method that is easy to separate. For example, an adhesive surface can be provided on the fixing device 2 to be attached to the patient's skin by bonding, or a plurality of suction cups can be provided on the fixing device 2 to be fixed to the patient's skin by adsorption. The electrode sheet 1 can be made of a metal material with good conductive properties. When the electrode sheet 1 is used to stimulate different parts of the body of patients with different body shapes, in order to ensure that the electrode sheet 1 is in full contact with the patient's skin, the electrode sheet 1 can be bent in advance so that the extension direction of the electrode sheet 1 is consistent with the curvature of the local skin surface of the patient. This allows the electrode sheet 1 to fit better on the patient's skin surface, thereby improving the treatment effect. As for the fixing device 2, medical staff can adjust the curvature of the fixing device 2 according to the curvature of the bent electrode sheet 1, so that the curvature of the fixing device 2 matches the curvature of the electrode sheet 1, and then the curvature of the fixing device 2 matches the patient's skin surface. When installing the electrode sheet 1 into the fixing device 2, it can not only ensure that the electrode sheet 1 is installed smoothly, but also ensure that the fixing device 2 has a stable clamping effect on the electrode sheet 1. At the same time, the fixing device 2 can be more firmly connected to the patient's skin surface, thereby avoiding poor contact between the electrode sheet 1 and the patient or even the fixing device 2 falling off the patient's body, thereby improving the treatment effect.

The medical staff can control the electrode sheet 1 to stimulate the patient's diaphragm contraction by operating the controller. When used on different body parts of patients with different body shapes, the medical staff can choose electrode sheets 1 with different curvatures and adjust the curvature of the fixing device 2 through the adjustment component 3, so that the fixing device 2 can be stably connected to the patient's skin surface, avoiding poor contact between the electrode sheet 1 and the patient or even falling off of the fixing device 2 from the patient's body, thereby improving the treatment effect.

The back plate assembly 21 is composed of a plurality of back plate members 211 and a rotation axis group 212. The back plate members 211 can rotate around a portion of the structure of the adjacent rotation axis group 212 so that the adjacent back plate members 211 can adjust the relative position. When the plurality of back plate members 211 rotate simultaneously, the overall shape of the back plate assembly 21 can be approximated to an arc shape, thereby matching the bent electrode sheet 1 and the patient's skin surface. The two most distant adjacent back plate members 211 are provided with a flange plate assembly 22. The flange plate assembly 22 The rotating shaft group 212 can be clamped from the side to fix the rotating shaft group 212.

The mounting plate 23 can protect the rotating shaft group 212 and improve the overall structural strength of the fixing device 2. The connecting plate 24 is connected between the ends of the two sets of flange plate assemblies 22 adjacent to the controller. The connecting plate 24 is provided with a wiring hole. The connecting plate 24 can protect the rotating shaft group 212 and improve the overall structural strength of the fixing device 2. Electronic components for connecting the rotating shaft group 212 and the wiring hole can be arranged on the side wall of the connecting plate 24 adjacent to the rotating shaft group 212.

A back plate member 211 is provided between the main shaft 2121 and the driven shaft 2122, and a back plate member 211 is provided between adjacent driven shafts 2122. The back plate members 211 at both ends of the main shaft 2121 can maintain a symmetrical position when rotating around the driven shaft 2122, so as to facilitate matching the curvature of the patient's local skin. The two ends of the main shaft 2121 are respectively fixed to the mounting plate 23 and the connecting plate 24, which can prevent the mounting plate 23 and the connecting plate 24 from being disengaged from the back plate assembly 21, thereby improving the overall structural strength of the fixing device 2.

[0048] refer to Figure 2-Figure 6According to some embodiments of the present invention, the adjustment assembly 3 includes multiple connecting members 31 and guide shafts 32, and connecting rings 311 are formed at both ends of the connecting member 31. The side of the connecting member 31 is connected to the back plate member 211 and the driven shaft 2122 or main shaft 2121 adjacent to the back plate member 211 is passed through the connecting ring 311, so that the back plate member 211 can be stably hinged with the adjacent driven shaft 2122 or driving shaft, and the lower end of the guide shaft 32 is formed with a guide ring 321 and the main shaft 2121 is passed through the guide ring 321, so that the guide shaft 32 can be stably hinged to the main shaft 2121. Multiple connecting members 31 can connect multiple back plate members 211, multiple driven shafts 2122 and main shaft 2121 into a whole to prevent the back plate member 211, the driven shaft 2122 and the main shaft 2121 from being out of coordination, thereby improving the structural reliability of the fixing device 2.

The adjusting wheel 331 is provided with a mounting groove 3311 that is snap-fitted with the adjusting sleeve 34. The adjusting sleeve 34 has the function of protecting the adjusting wheel 331. Through the cooperation of the gear part and the tooth part 322, the adjusting plate 33 can move up and down along the extension direction of the guide shaft 32. In this process, the adjusting rib 332 pulls the adjusting protrusion 312, thereby driving the connected back panel part 211 to rotate, thereby realizing the adjustment of the overall shape of the back panel assembly 21. When the adjusting wheel 331 moves upward, the two ends of the back panel assembly 21 tend to flip up, and when the adjusting wheel 331 moves downward, the two ends of the back panel assembly 21 tend to flip down.

[0050] refer to Figure 7-11When the adjusting wheel 331 is lowered relative to the guide shaft 32, the retracting component 3312 controls the adjustment rib 332 to extend; when the adjusting wheel 331 is raised relative to the guide shaft 32, the retracting component 3312 controls the adjustment rib 332 to shorten; and when the adjusting wheel 331 is lowered relative to the guide shaft 32, the retracting component 3312 controls the adjustment rib 332 to shorten. By allowing the adjustment shaft 3316 to move in the adjustment groove 3231, the adjustment plate 33 can be smoothly moved in the vertical direction, thereby facilitating adjustment of the overall shape of the back panel assembly 21. At the same time, by fine-tuning the length of the adjustment rib 332 through the retracting component 3312, the overall coordination and stability of the back panel assembly 21 can be further improved.

[0051] refer to Figure 7-11According to some embodiments of the present invention, the retractable assembly 3312 includes a retractable member 33121, a retractable shaft 33122, a retractable plate 33123, a contact member 33124, a transmission shaft 33125, and a transmission gear set 33126. The adjusting wheel 331 is hollow and defines a retractable space 3313. A first retractable hole 3314 is formed on the side wall of the adjusting wheel 331, through which the adjusting rib 332 is penetrated. There are multiple contact members 33124 and they are arranged in the retractable space 3313. The contact members 33124 correspond to and abut against the adjusting rib 332 one by one. The inner wall of the retractable space 3313 is formed with multiple holes suitable for The adjustment wheel 331 has a second expansion hole 3315 formed at its upper end to accommodate the contact member 33124. The expansion member 33121 is positioned within the expansion space 3313, with the contact member 33124 abutting against the expansion member 33121 and the contact member 33124. The expansion shaft 33122 passes through the second expansion hole 3315 and is fixedly connected to the expansion member 33121. The end of the adjustment shaft 3316, facing away from the expansion space 3313, is connected to a vertically extending transmission shaft 33125. The transmission shaft 33125 is hingedly connected to the expansion shaft 33122 via a transmission gear set 33126. When the medical staff lowers the adjustment wheel 331 relative to the guide shaft 32, the ends of the backplate assembly 21 tend to flip downward. At this time, the adjustment shaft 3316 moves downward in the adjustment slot 3231, thereby driving the conduction shaft 33125 to move downward, and driving the retraction shaft 33122 to move downward through the conduction gear set 33126, and then driving the retraction member 33121 to squeeze the retraction plate 33123 and the contact member 33124, thereby pushing part of the structure of the adjustment rib 332 out of the retraction space 3313, thereby improving the coordination of the overall structure when the back panel assembly 21 fine-tunes its shape; when the medical staff controls the adjustment wheel 331 to rise relative to the guide shaft 32, the two ends of the back panel assembly 21 tend to flip upward. At this time, the adjustment shaft 3316 moves upward in the adjustment slot 3231, thereby driving the transmission shaft 33125 to move upward, and driving the expansion and contraction shaft 33122 to move upward through the transmission gear set 33126, thereby driving the expansion and contraction member 33121 to reduce the squeezing strength of the expansion and contraction plate 33123 and the contact member 33124, thereby retracting part of the structure of the adjustment rib 332 into the expansion and contraction space 3313, thereby improving the coordination of the overall structure when the back panel assembly 21 fine-tunes its shape.

The root radius of the second transmission gear is greater than that of the transmission speed change gear. When the adjustment wheel 331 descends relative to the guide shaft 32, the retraction shaft 33122 can move downward relative to the adjustment wheel 331, allowing the retraction member 33121 to move downward relative to the adjustment wheel 331. When the adjustment wheel 331 ascends relative to the guide shaft 32, the retraction shaft 33122 can move upward relative to the adjustment wheel 331, allowing the retraction member 33121 to move upward relative to the adjustment wheel 331, thereby further improving the coordination of the overall structure.

The side plate 221 is away from the bottom wall of the back plate member 211 and is provided with an array-arranged adsorption portion 2211. The side plate 221 can position the electrode sheet 1 from the side. At the same time, the elastic limiting member 222 can press the electrode sheet 1 more stably. The limiting flange can prevent the electrode sheet 1 from sinking too deep and affecting the treatment effect. The adsorption portion 2211 can be a plurality of suction cups arranged in an array.
