DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the present application provides a set of electrocardiogram signal acquisition, for example, including: acquisition cable 20, a plurality of acquisition heads 30, a plurality of patch acquisition assemblies 40, a plurality of suction ball acquisition assemblies 50; it is worth mentioning that a plurality of patch acquisition assemblies 40 can have the same structure, for example, the structure of each patch acquisition assembly 40 is shown in Figure 2 ; and a plurality of suction ball acquisition assemblies 50 can have the same structure, for example, the structure of each suction ball acquisition assembly 50 is shown in Figure 4 and Figure 5 .

[0026] Specifically, the acquisition cable 20, for example, includes the electrocardiograph connection end 210 and a plurality of acquisition head connection ends 220, and the acquisition cable 20 is, for example, a lead wire. The plurality of acquisition heads 30 are connected to the plurality of acquisition head connection ends 220 of the acquisition cable 20 respectively, each patch acquisition assembly 40 includes an electrode patch 420 and an acquisition clamp 410 detachably connected with the electrode patch 420, and each suction ball acquisition assembly 50 includes a suction ball 510, a suction disc 530 and a conductive assembly 520 detachably connected between the suction ball 510 and the suction disc 530.

[0027] Furthermore, the electrocardiogram signal acquisition set of the embodiment can selectively be in a first use state and a second use state. When in the first use state, the plurality of acquisition heads 30 are in one-to-one electrical connection with the respective acquisition clamps 410 in the plurality of patch acquisition assemblies 40. When in the second use state, the plurality of acquisition heads 30 are in one-to-one electrical connection with the respective conductive assemblies 520 in the plurality of suction ball acquisition assemblies 50.

[0028] As described above, when acquiring electrocardiogram information, the acquisition assembly may not be well attached to the patient's skin, resulting in difficulties in electrocardiogram acquisition and causing large interference in the acquired information. Therefore, the embodiment of the utility model provides two use states, when one of the acquisition assemblies is not well attached to the patient's skin, the other acquisition assembly can be used for electrocardiogram acquisition to ensure accurate recording of electrocardiogram signals. When the electrocardiogram signal acquisition set is in use, the electrocardiogram machine connection end 210 of the acquisition cable 20 is connected to the electrocardiogram machine 10, the acquisition head connection end 220 of the acquisition cable 20 is connected to the acquisition head 30, and the acquisition head 30 is connected to the patch acquisition assembly 40 or the suction ball acquisition assembly 50, so as to switch the first use state and the second use state of the electrocardiogram signal acquisition set. The medical staff can select the appropriate acquisition assembly according to the needs to ensure accurate acquisition of electrocardiogram signals; the electrocardiogram machine 10 can also simultaneously acquire the electrical activity signals of the heart from multiple parts to obtain comprehensive electrocardiogram function information.

[0029] When the electrocardiogram signal acquisition set is in the first use state, the acquisition head 30 is connected to the patch acquisition assembly 40, the acquisition head 30 receives the electrocardiogram signals of the patient through the patch acquisition assembly 40, and transmits them to the electrocardiogram machine 10 for further processing and analysis. The patch acquisition assembly 40 includes an electrode patch 420 and an acquisition clamp 410. The electrode patch 420 is in contact with the patient's skin, for example, through conductive gel to improve comfort and conductivity. The acquisition clamp 410 is connected to the electrode patch 420, and the electrocardiogram signals detected by the electrode patch 420 are transmitted to the electrocardiogram machine 10 through the acquisition cable 20. The electrode patch 420 is, for example, a disposable patch, which helps to reduce the risk of cross infection and simplify the cleaning and disinfection process of the equipment.

[0030] When the ECG signal acquisition kit is in its second usage state, the acquisition head 30 is connected to the suction bulb acquisition assembly 50. The acquisition head 30 receives the patient's ECG signal through the conduction of the suction bulb acquisition assembly 50 and transmits it to the ECG machine 10 for further processing and analysis. The suction bulb acquisition assembly 50 includes a suction bulb 510, a suction cup 530, and a conductive assembly 520. The conductive assembly 520 is, for example, a structure with open top and bottom. The suction bulb 510 is connected to the suction cup 530 through the conductive assembly 520. The suction cup 530 is, for example, made of a flexible material such as silicone, which can deform to fit tightly against the patient's skin and reduce air gaps. The conductive assembly 520 is connected to the acquisition head 30 to transmit the acquired ECG information. In use, by pressing the suction bulb 510 to expel air, the suction cup 530 is placed on the patient's skin, allowing the suction cup 530 to adhere tightly to the patient's skin. The conductive component 520 can have good contact with the patient's skin. The connection between the conductive component 520 and the acquisition head 30 ensures continuous transmission of electrocardiogram signals, which helps to improve the accuracy and reliability of electrocardiogram detection.

[0031] In some embodiments, such as Figure 2 As shown, the acquisition clip 410 includes, for example, a first clip 411 and a second clip 412 pivotally connected to the first clip 411 to provide flexible and stable clamping. The first clip 411 has a first clamping end 4111, and the second clip 412 has a second clamping end 4121 and a plug-in end 4122. The first clamping end 4111 and the second clamping end 4121 are movable relative to each other to clamp the electrode patch 420. The plug-in end 4122 is used for plugging into the corresponding acquisition head 30 so that the acquisition clip 410 and the corresponding acquisition head 30 form an electrical connection. The first clamp 411 has a first pressure handle end opposite to the first clamping end 4111, and the second clamp 412 has a second pressure handle end opposite to the second clamping end 4121. Medical personnel press the first pressure handle end and the second pressure handle end to bring them closer together, while the first clamping end 4111 and the second clamping end 4121 move away from each other. After placing the acquisition clamp 410 on the electrode patch 420, the first pressure handle end and the second pressure handle end are released, so that the electrode patch 420 is clamped and fixed by the first clamping end 4111 and the second clamping end 4121. The acquisition head 30 is then plugged into the plug end 4122 to form an electrical connection. The electrocardiogram signal is transmitted from the electrode patch 420 to the acquisition head 30 through the acquisition clamp 410, and then the acquisition head 30 transmits the signal to the electrocardiograph 10 through the acquisition cable 20 for further processing and analysis.

[0032] In some embodiments, such as Figure 2 As shown, the plug-in end 4122 is, for example, a hollow conical cylindrical structure. The acquisition head 30 is inserted into the plug-in end 4122 and connected to the plug-in end 4122, thereby strengthening the stability of the connection between the acquisition head 30 and the acquisition clip 410.

[0033] In some embodiments, as shown in Figure 2 The opposite surfaces of the first clamping end 4111 and the second clamping end 4121 have a sawtooth structure, which increases the friction and improves the stability when the clamping connection with the electrode patch 420 is made, preventing the disconnection of the electrode patch 420 and the electrode patch 420 during electrocardiogram monitoring due to patient activity or other external factors.

[0034] In some embodiments, as shown in Figure 3 The electrode patch 420, for example, includes a patch 421, a conductive female buckle 422, a conductive male buckle 423, an electrode head 424, and a conductive gel 425. The conductive male buckle 423 is buckled through the patch 421 and the conductive female buckle 422. The electrode head 424 is located on the side of the conductive female buckle 422 away from the patch 421, and the electrode head 424 is used for clamping and fixing the clamping clamp 410. The conductive gel 425 is arranged on the side of the conductive male buckle 423 away from the patch 421. The conductive male buckle 423, for example, includes a first fixing part and a fixing shaft arranged on the first fixing part and integrally formed with the fixing shaft. The conductive female buckle 422, for example, includes a second fixing part and a socket arranged on the second fixing part and matched with the fixing shaft. The fixing shaft of the conductive male buckle 423 is inserted into the socket after passing through the patch 421, thereby fixing the patch 421 between the conductive female buckle 422 and the conductive male buckle 423. In use, the electrode patch 420 with the conductive gel 425 can be attached to the skin of the patient, and the clamping clamp 410 is clamped and connected to the electrode head 424 on the electrode patch 420. Through the cooperation of the conductive gel 425, the conductive male buckle 423, the conductive female buckle 422, and the electrode head 424, the electrocardiogram signal of the patient can be collected.

[0035] In some embodiments, as shown in Figure 4 and Figure 5 The conductive assembly 520, for example, includes a conductive pipe 521, a conductive plate 522, a conductive sheet 523, and an elastic connecting piece 524. The conductive pipe 521 is detachably connected between the suction ball 510 and the suction disc 530. The outer wall of the conductive pipe 521 is provided with a plug-in ring 5211 for connecting the collection head 30. The plug-in ring 5211, for example, is an annular groove and at least one is provided. The conductive plate 522 is located inside the conductive pipe 521 and is electrically connected with the conductive pipe 521. The conductive sheet 523 is located inside the suction disc 530 and is connected with the conductive plate 522 through the elastic connecting piece 524. The elastic connecting piece 524, for example, includes a spring. The conductive assembly 520, for example, further includes a guide rod, one end of which is connected with the conductive sheet 523, and the other end of which passes through the conductive plate 522 and is connected with a limiting block. The elastic connecting piece 524 is sleeved on the guide rod, so that when the elastic connecting piece 524 is compressed or rebounds in the direction of the guide rod, the conductive sheet 523 is driven to move in the direction of the guide rod. The conductive plate 522, for example, is provided with a through hole for connecting the inner cavity of the suction ball 510 with the inner cavity of the suction disc 530.

[0036] Specifically, in use, the medical staff first connects the collection head 30 with the plug-in ring 5211 of the conductive assembly 520, then squeezes the suction ball 510 to discharge the air in the suction ball 510, and adsorbs the suction disc 530 on the patient's skin. Since the suction disc 530 will be deformed in the process of adsorption, the height of the suction disc 530 will be lowered, the conductive sheet 523 will be attached to the patient's skin, the conductive sheet 523 will move to compress the elastic connecting piece 524, at this time, the elastic connecting piece 524 will give the conductive sheet 523 a force opposite to the compression direction, to ensure that the conductive sheet 523 is tightly attached to the patient's skin, and to realize effective transmission of the electrocardiogram signal.

[0037] In some embodiments, as shown in Figure 4 and Figure 5 , the suction ball 510, for example, includes an outer shell 511 and an inner container 512, a containing space is formed between the outer shell 511 and the inner container 512, an end of the suction ball 510 close to the suction disc 530 is provided with a through hole 513 in communication with the containing space, a first channel 5212 is arranged in the side wall of the conductive tube 521, a second channel 531 is arranged in the side wall of the suction disc 530, and the second channel 531 is in communication with the through hole 513 through the first channel 5212. Furthermore, the top of the suction ball 510 is provided with an opening, the opening is in communication with the containing space, and a cover plate is detachably connected at the opening, to facilitate pouring alcohol from the opening of the suction ball 510, store the alcohol in the containing space, cover the cover plate after pouring the alcohol, to ensure that the alcohol does not leak from the opening, to avoid waste of alcohol, and to avoid the need to disinfect the skin with alcohol before adsorbing the suction ball collection assembly 50 on the patient's skin. When the suction ball 510 is squeezed, the alcohol in the suction ball 510 flows out through the through hole 513, the first channel 5212 and the second channel 531, and disinfects the patient's skin, to simplify the disinfection process and improve work efficiency.

[0038] In some embodiments, a one-way valve (not shown in the figure) is arranged inside the through hole 513, to ensure that the alcohol will only flow out when the suction ball 510 is squeezed, and the alcohol will be stored in the containing space when not squeezed, and to ensure that the alcohol will not continue to enter the suction disc 530 when the suction ball 510 is released.

[0039] In some embodiments, as shown in Figure 6As shown, the ECG signal acquisition set further comprises a distribution box 60, the distribution box 60 is movable along the acquisition cable 20, the inside of the distribution box 60 is divided into a plurality of independent accommodating cavities 620 by a partition plate 610, the two ends of each accommodating cavity 620 are respectively formed with an inlet port 630 and an outlet port 640, the inlet port 630 and the outlet port 640 are used for the acquisition head connecting end 220 to pass through in sequence, so that the plurality of acquisition head connecting ends 220 of the acquisition cable 20 are in a mutually independent state in the distribution box 60, effectively preventing the occurrence of winding and kinking in the use process, without spending time to untangle the acquisition cable 20, and the work efficiency of medical staff is improved.
