Description

Technical Field

[0001] The utility model relates to a monitoring device, in particular to a portable electrocardiogram monitoring device for clinical use. Background Art

[0002] Electrocardiogram (ECG) monitoring is an important method for detecting and evaluating cardiac electrical activity. It can help doctors diagnose heart disease, evaluate cardiac function, and monitor patients' health. The ECG records the temporal changes in the heart's electrical signals and reveals the heart's excitation and repolarization processes. By observing the shape and intervals of the ECG waveform, doctors can determine the heart's health and whether there are any abnormalities.

[0003] Existing clinical portable ECG monitoring devices include small wireless types. Such ECG monitoring devices mainly place the entire ECG monitoring device directly on the patient's skin through ECG electrodes. Although such ECG monitoring devices have the advantages of portability, flexibility, convenience and long-term monitoring, they mainly rely on the ECG electrodes to contact the patient's skin for monitoring, and the ECG electrodes often need to be replaced. Existing small wireless ECG monitoring devices often have a cumbersome process of replacing ECG electrodes, and since the small wireless ECG monitoring devices and ECG electrodes in the prior art are mostly separately connected (that is, the ECG electrodes and the small wireless ECG monitoring device are only connected by a snap, and there are no other restrictions between the two), there is a risk that the ECG monitoring device body will fall off the ECG electrodes due to long-term friction with clothing during use. Utility Model Content

[0004] In view of this, the present invention provides a portable clinical electrocardiogram monitoring device, which is easy to install and not easy to fall off.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A portable electrocardiogram monitoring device for clinical use comprises a shell, a monitoring body arranged in the middle of the shell, two groups of adjustment components arranged in the shell and symmetrically arranged on the left and right sides of the monitoring body, and a shell cover rotatably arranged at the bottom of the shell; the adjustment component comprises a mounting groove opened at the bottom of the shell, an electrocardiogram electrode is correspondingly arranged in the mounting groove, a card slot is integrally formed upward at the center position of the top of the mounting groove, an electrode snap is clamped in the card slot, an annular groove is opened on the shell corresponding to the top of the mounting groove, an adjustment ring body is slidably arranged in the annular groove, a rack is fixedly provided on the upper rear side of the inner ring wall of the adjustment ring body, a micro gear is meshed with the front side of the rack, the micro gear is fixedly connected to one end of a micro stepped shaft, and the end of the other end of the micro stepped shaft extends horizontally to the outside of the shell and is fixedly connected to a knob.

[0008] Preferably, a second limiting assembly is provided on the rear inner wall of the shell corresponding to the rack, and the second limiting assembly includes a sliding limiting rod located on the rear side of the rack and horizontally integrally formed backward, and the rear end of the sliding limiting rod is slidably provided in the limiting strip located on the rear inner wall of the shell, and a limiting groove is provided in the limiting strip corresponding to the sliding limiting rod.

[0009] Preferably, a contact groove is formed on the shell cover corresponding to the installation groove, and the diameter of the contact groove is not greater than the diameter of the installation groove.

[0010] Preferably, a groove is provided at the bottom of the shell cover, and an auxiliary block is provided in the groove.

[0011] Preferably, the middle portion of the sliding limiting rod extends downward to the top end of the adjusting ring body and is fixedly connected to the adjusting ring body.

[0012] Preferably, the shell cover is made of fluororubber material.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model includes a shell, a monitoring body arranged in the middle of the shell, two groups of adjustment components arranged in the shell and symmetrically arranged on the left and right sides of the monitoring body, and a shell cover rotatably arranged at the bottom of the shell. The monitoring body includes conventional known structures in the prior art such as wireless lead wires, preamplifiers, filters, analog-to-digital converters (ADCs), microprocessors / controllers, wireless communication modules, power management modules, and storage devices. The monitoring body does not serve as a protection point in this embodiment, so it will not be described in detail. This arrangement allows the ECG electrodes to be replaced by opening the shell cover, and after the replacement is completed, the shell cover is replaced. Then, the installed ECG electrodes are slightly squeezed by the adjustment components so that the bottom of the ECG electrode is slightly lower than the bottom end surface of the shell cover (relative to when the shell cover is placed downward). The entire small wireless ECG monitoring device is convenient for rapid bonding and fixing to the patient's skin surface, and then the patient's cardiac electrical activity is monitored through the monitoring body. Generally speaking, compared with previous clinical portable small wireless ECG monitoring devices, this clinical portable ECG monitoring device can quickly replace the ECG electrode sheet and can fine-tune the position of the bottom of the ECG electrode sheet. Through fine-tuning of the ECG electrode sheet and the restriction of the shell cover on the edge of the ECG electrode sheet, the contact between the device and the patient's skin surface is more secure during the entire use process. Compared with the previous small wireless ECG monitoring device and the ECG electrode sheet's separate connection method, this setting greatly reduces the possibility of the small wireless ECG monitoring device slipping off the ECG electrode sheet during use, making it more secure and practical.The adjustment component includes a mounting groove provided at the bottom of the shell, an ECG electrode sheet is provided in the mounting groove correspondingly, a card slot is integrally formed upward at the center position of the top of the mounting groove, an electrode sheet snap is clamped in the card slot, an annular groove is provided on the shell corresponding to the top of the mounting groove, an adjustment ring body is slidably provided in the annular groove, a rack is fixedly provided on the upper rear side of the inner ring wall of the adjustment ring body, a micro gear is meshed with the front side of the rack, the micro gear is fixedly connected to one end of the micro stepped shaft, the end of the other end of the micro stepped shaft extends horizontally to the outside of the shell and is fixedly connected to a knob, wherein the micro stepped shaft is rotationally connected to the shell, and a supporting rotation fixing part is also provided in the middle of the micro stepped shaft, the upper part of the supporting rotation fixing part is rod-shaped, and the lower part is connected to the outer periphery of the micro stepped shaft The adapted cylinder, the micro-stepped shaft, is rotatably arranged within the cylinder at the bottom of the supporting rotating fixture. The top end of the supporting rotating fixture is fixedly connected to the top inner wall of the housing. The supporting and fixing assembly helps prevent the micro-stepped shaft from tilting and affecting the adjustment effect of the adjustment assembly. The knob is similar to the knob on a watch in the prior art. This arrangement drives the micro-stepped shaft and the micro-gear on it to rotate by hand. Then, due to the meshing connection between the micro-gear and the rack, the rack moves up and down, which in turn drives the adjustment ring body to move up and down synchronously, thereby facilitating the installation and fine-tuning of the ECG electrode pads. The entire process is simple in principle and easy to operate, allowing for rapid replacement of ECG electrode pads and fine-tuning of the bottom position of the ECG electrode pads.

[0015] 2. The top and bottom of the rack of the utility model are symmetrically provided with two groups of first limit assemblies, and the first limit assembly includes two fixing parts fixedly provided on the left and right side walls of the rack, the two fixing parts are fixedly connected to one end of a limit column respectively, and the other ends of the two limit columns are slidably connected to the limit tooth block together, and the fixing parts are connected to the limit tooth block by a spring, and the spring is correspondingly sleeved on the periphery of the limit column. This arrangement can limit the rack during its up and down sliding process, specifically: when the rack rises (falls) to the highest point (lowest point) as the micro gear rotates (reverses), the teeth at the bottom (top) end of the rack are separated from the teeth of the micro gear. At this time, the structure meshing with the micro gear is the limit tooth block located at the bottom (top) of the rack. At this time, as the micro gear rotates, The limiting tooth block is pushed to slide upward (downward) around the limiting column and the spring is compressed. When the teeth on the micro gear that are engaged with the limiting tooth block are separated from the teeth on the limiting tooth block, the spring is reset. At the same time, the limiting tooth block slides downward (upward) so that the teeth on it are re-engaged with the teeth on the micro gear. As the micro gear rotates, the limiting tooth block is pushed upward (downward) around the limiting column and the spring is compressed again. As the micro gear rotates, this process will be repeated, but the position height of the rack does not change. Therefore, during the above-mentioned multiple cycles, the adjusting ring body is always at the highest point (lowest point) of its sliding stroke and remains stationary at this position. Therefore, the adjusting ring body can be quickly limited. The whole process has a simple principle and easy operation, which is convenient for height adjustment and limiting of the adjusting ring body.

[0016] 3. A second limit assembly is provided on the rear inner wall of the shell of the utility model corresponding to the rack. The second limit assembly includes a sliding limit rod located on the rear side of the rack and horizontally integrally formed backward. The rear end of the sliding limit rod is slidably arranged in the limit strip located on the rear inner wall of the shell. A limiting groove is provided in the limit strip corresponding to the sliding limit rod. This arrangement enables the sliding limit rod to slide up and down in the limiting groove as the rack moves up and down, and can form a double limit together with the first limit assembly, making the entire adjustment process of the adjustment ring body smoother.

[0017] 4. A contact groove is provided on the shell cover of the utility model corresponding to the mounting groove, and the diameter of the contact groove is not larger than the diameter of the mounting groove. This arrangement enables the adjusting ring body to slightly squeeze the ECG electrode sheet so that the squeezed portion of the ECG electrode sheet protrudes slightly toward the outside of the shell cover. At the same time, since the diameter of the contact groove is not larger than the diameter of the mounting groove, the edge of the ECG electrode sheet is placed inside the shell, thereby making the small wireless ECG monitoring device more firmly in contact with the patient's skin surface during the entire use process. Compared with previous wireless ECG monitoring devices, this arrangement greatly reduces the possibility of the small wireless ECG monitoring device slipping off the ECG electrode sheet during use, making it more practical.

[0018] 5. A groove is provided at the bottom of the shell cover of the present invention, and an auxiliary block is provided in the groove. This arrangement facilitates the patient to open and close the shell cover, thereby enabling rapid replacement of the ECG electrodes.

[0019] 6. The middle part of the sliding limit rod of the utility model extends downward to the top of the adjusting ring body and is fixedly connected to the adjusting ring body. This arrangement makes it difficult for the sliding limit rod to tilt during the process of rising (falling) with the rack and the adjusting ring body, thereby avoiding it from deviating from the limiting slide groove, making the entire adjustment process more stable.

[0020] 7. The shell cover of this utility model is made of fluororubber material, which has excellent properties such as high temperature resistance, chemical corrosion resistance, and aging resistance, which increases the service life of this device to a certain extent.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, it includes a shell 1, a monitoring body 2 arranged in the middle of the shell 1, two groups of adjustment components 3 arranged in the shell 1 and symmetrically arranged on the left and right sides of the monitoring body 2, and a shell cover 4 rotatably arranged at the bottom of the shell 1. The monitoring body 2 includes conventional known structures in the prior art such as wireless lead wires, preamplifiers, filters, analog-to-digital converters (ADCs), microprocessors / controllers, wireless communication modules, power management modules, storage devices, etc. The monitoring body 2 is not used as a protection point in this embodiment, so it will not be described in detail. This setting can replace the ECG electrode sheet 6 by opening the shell cover 4, and after the replacement is completed, the shell cover 4 is covered, and then the installed ECG electrode sheet 6 is slightly squeezed by the adjustment component 3, so that the bottom of the ECG electrode sheet 6 is slightly lower than the shell cover 4 (relative to when the shell cover 4 is placed downwards) The bottom end surface of the shell 4 facilitates the rapid bonding and fixing of the entire small wireless ECG monitoring device to the patient's skin surface, and then monitors the patient's cardiac electrical activity through the monitoring body 2. Generally speaking, compared with previous clinical portable ECG monitoring devices, this clinical portable ECG monitoring device can quickly replace the ECG electrode sheet 6 and can fine-tune the position of the bottom of the ECG electrode sheet 6. The fine-tuning of the ECG electrode sheet 6 and the restriction of the shell cover 4 on the edge of the ECG electrode sheet 6 make the contact between the device and the patient's skin surface more secure during the entire use process. Compared with the previous small wireless ECG monitoring device and the ECG electrode sheet 6 separated connection method, this setting greatly reduces the possibility of the small wireless ECG monitoring device slipping off the ECG electrode sheet 6 during use, making it more secure and practical.The adjustment component 3 includes a mounting groove 5 provided at the bottom of the shell 1, in which an ECG electrode 6 is correspondingly provided, a card slot 7 is integrally formed upward at the center position of the top of the mounting groove 5, and an electrode snap 8 is clamped in the card slot 7, and an annular groove 9 is provided on the shell 1 corresponding to the top of the mounting groove 5, and an adjustment ring body 10 is slidably provided in the annular groove 9, and a rack 11 is fixedly provided on the upper rear side of the inner ring wall of the adjustment ring body 10, and a micro gear 12 is meshed with the front side of the rack 11, and the micro gear 12 is fixedly connected to one end of a micro stepped shaft 13, and the end of the other end of the micro stepped shaft 13 extends horizontally to the outside of the shell 1 and is fixedly connected to a knob 14, wherein the micro stepped shaft 13 is rotatably connected to the shell 1, and a supporting rotation fixing part 27 is also provided in the middle part of the micro stepped shaft 13, and the upper part of the supporting rotation fixing part 27 is rod-shaped and the lower part is connected to the micro step The outer periphery of the ladder shaft 13 is adapted to the cylinder, and the micro-stepped shaft 13 is rotatably arranged in the cylinder at the bottom of the supporting rotating fixture 27. The top end of the supporting rotating fixture 27 is fixedly connected to the top inner wall of the housing 1. The supporting and fixing assembly helps to prevent the micro-stepped shaft 13 from tilting and affecting the adjustment effect of the adjustment assembly 3. The knob 14 is similar to the knob 14 on the watch in the prior art. This arrangement drives the micro-stepped shaft 13 and the micro-gear 12 thereon to rotate by hand-held knob 14. Then, due to the meshing connection between the micro-gear 12 and the rack 11, the rack 11 moves up and down, thereby driving the adjustment ring body 10 to move up and down synchronously, thereby facilitating the installation and fine-tuning of the ECG electrode sheet 6. The entire process is simple in principle and easy to operate, and can quickly achieve the replacement of the ECG electrode sheet 6, and can also fine-tune the position of the bottom of the ECG electrode sheet 6.

[0032] like Figure 1 、 Figure 5 and Figure 6As shown, the top and bottom of the rack 11 are symmetrically provided with two groups of first limit components 15. The first limit component 15 includes two fixing members 16 fixedly provided on the left and right side walls of the rack 11. The two fixing members 16 are respectively fixedly connected to one end of a limit column 17. The other ends of the two limit columns 17 are slidably connected to the limit tooth block 18. The fixing members 16 and the limit tooth block 18 are connected by a spring 19. The spring 19 is correspondingly sleeved on the periphery of the limit column 17. This setting can limit the rack 11 during its up and down sliding process. Specifically, when the rack 11 rises (falls) to the highest point (lowest point) with the forward (reverse) rotation of the micro gear 12, the teeth at the bottom (top) end of the rack 11 are separated from the teeth of the micro gear 12. At this time, the structure meshing with the micro gear 12 is the limit tooth block 18 located at the bottom (top) of the rack 11. At this time, as the micro gear 12 The rotation pushes the limit tooth block 18 to slide upward (downward) around the limit column 17 and compresses the spring 19. When the teeth on the micro gear 12 that are engaged with the limit tooth block 18 are separated from the teeth on the limit tooth block 18, the spring 19 resets, and at the same time, the limit tooth block 18 slides downward (upward) so that the teeth on it re-engage with the teeth on the micro gear 12. As the micro gear 12 rotates, the limit tooth block 18 is again pushed to slide upward (downward) around the limit column 17 and compress the spring 19. As the micro gear 12 rotates, this process will be repeated, but the position height of the rack 11 does not change. Therefore, during the above-mentioned multiple cycles, the adjusting ring body 10 is always at the highest point (lowest point) of its sliding stroke and remains stationary at this position. Therefore, the adjusting ring body 10 can be quickly limited. The whole process is simple in principle and easy to operate, and it is convenient to adjust the height and limit the adjusting ring body 10.

[0033] like Figure 2 、 Figure 5 and Figure 6 As shown, a second limiting assembly 20 is provided on the rear inner wall of the shell 1 corresponding to the rack 11. The second limiting assembly 20 includes a sliding limiting rod 21 located on the rear side of the rack 11 and horizontally integrally formed backward. The rear end of the sliding limiting rod 21 is slidably arranged in a limiting strip 22 located on the rear inner wall of the shell 1. A limiting groove 23 is provided in the limiting strip 22 corresponding to the sliding limiting rod 21. This arrangement enables the sliding limiting rod 21 to slide up and down in the limiting groove 23 as the rack 11 moves up and down, and can form a double limit together with the first limiting assembly 15, so that the entire adjustment process of the adjustment ring body 10 is smoother.

[0034] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, a contact groove 24 is provided on the shell cover 4 corresponding to the mounting groove 5, and the diameter of the contact groove 24 is not larger than the diameter of the mounting groove 5. This arrangement enables the adjustment ring body 10 to slightly squeeze the ECG electrode sheet 6 so that the squeezed portion of the ECG electrode sheet 6 slightly protrudes toward the outside of the shell cover 4. At the same time, since the diameter of the contact groove 24 is not larger than the diameter of the mounting groove 5, the edge of the ECG electrode sheet 6 is placed inside the shell 1, so that the small wireless ECG monitoring device has a stronger contact with the patient's skin surface during the entire use process. Compared with previous wireless ECG monitoring devices, this arrangement greatly reduces the possibility of the small wireless ECG monitoring device slipping off the ECG electrode sheet 6 during use, and is more practical.

[0035] like Figure 3 and Figure 4 As shown, a groove 25 is provided at the bottom of the shell cover 4 , and an auxiliary block 26 is provided in the groove 25 . This arrangement facilitates the patient to open and close the shell cover 4 , thereby enabling rapid replacement of the ECG electrode sheet 6 .

[0036] like Figure 5 As shown, the middle part of the sliding limit rod 21 extends downward to the top of the adjusting ring body 10 and is fixedly connected to the adjusting ring body 10. This arrangement makes it difficult for the sliding limit rod 21 to tilt during the process of rising (falling) with the rack 11 and the adjusting ring body 10, thereby avoiding it from deviating from the limiting slide groove 23, making the entire adjustment process more stable.

[0037] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the shell cover 4 is made of fluororubber material, which has excellent properties such as high temperature resistance, chemical corrosion resistance, and aging resistance, which increases the service life of the device to a certain extent.

[0038] The specific operating principle is:

[0039] When using this ECG monitoring device, you first need to pull the auxiliary block with your fingers to rotate the shell cover open, snap the electrode snaps of the ECG electrode into the card slot, then tear off the transparent release film on the ECG electrode, and manually close the shell cover again; by reversing the hand-held knob, the micro-step shaft and the micro-gear on it are driven to reverse synchronously, and then due to the meshing connection between the micro-gear and the rack, the rack moves downward and drives the adjustment ring body to move downward synchronously, thereby facilitating the installation and fine-tuning of the ECG electrode. When the rack drops to the lowest point as the micro-gear reverses, the top teeth of the rack are separated from the teeth of the micro-gear. At this time, the structure meshed with the micro-gear is the limiting tooth block located at the top of the rack. At this time, as the micro-gear rotates, the limiting tooth block is pushed to slide downward around the limiting column and compress the spring. When the teeth on the micro-gear that are meshed with the limiting tooth block are separated from the teeth on the limiting tooth block, the spring resets and the limiting tooth block slides upward at the same time. The teeth on it are re-engaged with the teeth on the micro-gear, and as the micro-gear rotates, the limiting tooth block is pushed down again on the periphery of the limiting column and compresses the spring. As the micro-gear rotates, this process will be repeated, but the position height of the rack does not change. Therefore, during the above-mentioned multiple cycles, the adjustment ring body is always at the lowest point of its sliding stroke and remains stationary at this position, so the adjustment ring body can be quickly limited. At this time, the bottom of the ECG electrode sheet after being squeezed by the adjustment ring body is slightly lower than the bottom end surface of the shell cover (relative to when the shell cover is placed downward), which facilitates the rapid bonding and fixing of the entire ECG monitoring device to the patient's skin surface, and then the patient's cardiac electrical activity is monitored through the monitoring body. At the same time, during the process of adjusting the limit of the adjustment ring body, the sliding limit rod can slide downward in the limiting slide groove as the rack moves downward, and can form a double limit together with the first limiting component, making the entire adjustment process of the adjustment ring body smoother;When the ECG electrode needs to be replaced, the handheld knob is turned forward to drive the micro-step shaft and the micro-gear on it to rotate forward, and then the rack moves upward due to the meshing connection between the micro-gear and the rack, thereby driving the adjustment ring to move upward synchronously. When the rack rises to the highest point with the forward rotation of the micro-gear, the teeth at the bottom of the rack are separated from the teeth of the micro-gear. At this time, the structure meshed with the micro-gear is the limiting tooth block located at the bottom of the rack. At this time, as the micro-gear rotates, the limiting tooth block is pushed to slide upward around the limiting column and compress the spring. The moment the teeth on the micro-gear that mesh with the limit tooth block separate from the teeth on the limit tooth block, the spring resets, and the limit tooth block slides downward, causing its teeth to re-engage with those on the micro-gear. As the micro-gear rotates, the limit tooth block is again pushed upward around the limit column and compresses the spring. This process repeats as the micro-gear rotates, but the position and height of the rack do not change. Therefore, during these multiple cycles, the adjustment ring body always remains at the highest point of its sliding travel and remains stationary in this position. At this time, the housing cover can be opened to replace the ECG electrodes.
