Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram (ECG) recorder technology, specifically to a patch-type ECG recorder. Background Technology

[0002] A search revealed Chinese patent number CN202121877403.6, which discloses a wearable dynamic electrocardiogram (ECG) recorder, including a housing and electrode patches. The housing has an internal partition dividing it into an upper cavity and a lower cavity. The upper cavity houses a data processing mechanism, while the lower cavity houses a fixing mechanism. The fixing mechanism includes a fixing rod, a sliding rod, and a connecting rod. The connecting rod has a pressure block, the fixing rod has a spring, the lower cavity has a connecting tube, and the electrode patches have snap fasteners with locking holes. The sliding rod has a locking block, and the connecting tube has a slot. The locking block engages with the locking hole on the snap fastener, ensuring a more stable connection between the electrode patches and the housing, preventing disengagement, avoiding damage or loss of the ECG recorder, and facilitating the removal and replacement of the electrode patches.

[0003] However, the above solution still has its flaws. The fixing mechanism includes two fixing rods, two sliding rods, two connecting rods, two pressure blocks, four springs, two connecting tubes, and four locking blocks. In other words, the fixing mechanism has a lot of components, which leads to higher production costs and increases the overall cost of the ECG recorder, resulting in a poor user experience.

[0011] One end of the spring and one end of the guide rod are both fixed inside the housing. The other end of the spring is fixed to the outer wall of the U-shaped plate. The guide rod slides through the U-shaped plate and is slidably inserted into the L-shaped rod. The L-shaped rod also passes through the partition and the housing. The end of the U-shaped plate is inserted into the lock hole.

[0012] In one embodiment of this application, the L-shaped rod has a slot, and the guide rod is slidably inserted into the slot.

[0029] Please see Figures 1-8 This application provides a technical solution: a patch-type electrocardiogram recorder, including a housing 110, a partition 120, a signal converter 130, a processor 140, a signal transmitter 150, a battery 160, electrode patches 170, elastic conductive terminals 190, and a locking mechanism 180. The partition 120 is fixed inside the housing 110, and the signal converter 130, the processor 140, the signal transmitter 150, and the battery 160 are all disposed on the partition 120.

[0030] The bottom of the signal converter 130 is provided with an elastic conductive terminal 190, which extends into the connecting tube 186. The electrode patch 170 is provided on the housing 110. The electrode patch 170 and the elastic conductive terminal 190 are electrically connected together. The electrode patch 170 includes a patch 171, a snap fastener 172 and a conductive sheet 174. The snap fastener 172 is provided on the upper surface of the patch 171. A locking hole 173 is provided on the snap fastener 172. The conductive sheet 174 is installed on the snap fastener 172. The snap fastener 172 penetrates the housing 110. A first through hole 191 is provided on the housing 110. The snap fastener 172 penetrates the first through hole 191.

[0031] The locking mechanism 180 is installed inside the housing 110. The locking mechanism 180 secures the buckle 172 inside the connecting tube 186 and causes the conductive sheet 174 to abut against the elastic conductive terminal 190. The locking mechanism 180 includes an L-shaped rod 181, a spring 183, a guide rod 184, a U-shaped plate 185, and a connecting tube 186. The connecting tube 186 is fixed to the lower surface of the partition 120. The U-shaped plate 185 slides through the connecting tube 186. One end of the L-shaped rod 181 is fixed to the outer wall of the U-shaped plate 185. One end of the spring 183 and one end of the guide rod 184 are both fixed inside the housing 110. The other end is fixed to the outer wall of the U-shaped plate 185. The guide rod 184 slides through the U-shaped plate 185 and is slidably inserted into the L-shaped rod 181. The L-shaped rod 181 also passes through the partition 120 and the housing 110. The end of the U-shaped plate 185 is inserted into the lock hole 173. The L-shaped rod 181 has a slot 182. The guide rod 184 slides into the slot 182. The partition 120 has a second through hole 192. The housing 110 has a third through hole 193. The second through hole 192 and the third through hole 193 are correspondingly arranged. The L-shaped rod 181 passes through the second through hole 192 and the third through hole 193.

[0032] The working principle and process of this utility model are as follows: In use, simultaneously push the two L-shaped rods 181 to move them away from each other. Under the action of the guide rod 184 and the spring 183, the end of the U-shaped plate 185 is completely misaligned with the elastic conductive terminal 190. Then, insert the buckle 172 into the connecting tube 186 through the first through hole 191, so that the conductive piece 174 abuts against the elastic conductive terminal 190. Then release the two L-shaped rods 181. Under the action of the spring 183, the two L-shaped rods 181 move closer to each other. When the L-shaped rods 181 do not reach the expected position, rotate the patch 171 to allow the end of the U-shaped plate 185 to enter the lock. The buckle 172 is fixed inside the connecting tube 186 within the hole 173, thus enabling the installation of the patch 171. When the patch 171 needs to be removed, the two L-shaped rods 181 are operated according to the above steps to move the end of the U-shaped plate 185 away from the locking hole 173, thereby removing the patch 171. The locking mechanism 180 in this patch-type ECG recorder includes two L-shaped rods 181, two springs 183, two guide rods 184, two U-shaped plates 185, and two connecting tubes 186, which enables the installation of the buckle 172. This reduces the production cost of the locking mechanism 180, thereby reducing the overall cost of the ECG recorder and providing users with a better user experience.

[0033] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
