Common examination items include electrocardiogram, echocardiogram, blood test, cardiac magnetic resonance imaging, and cardiovascular angiography.

[0003] When performing an electrocardiogram (ECG) examination, the patient's chest must first be disinfected with alcohol, and then the medical staff will use cotton balls or cotton swabs to apply conductive fluid. After completing the ECG monitoring, the conductive fluid on the skin and electrodes should be cleaned in time to keep the skin clean and dry.

Detailed implementation manners

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Embodiment 1

[0036] As Figure 1 shown, an auxiliary inspection device for cardiovascular diseases includes a handle 1. The lower end of the handle 1 is fixedly connected with a conductive liquid supply structure 2. The left end and the right end of the conductive liquid supply structure 2 are symmetrically and fixedly connected with driving structures 3. The symmetrically arranged ends of the two driving structures 3 away from each other are provided with a disinfection and cleaning structure 5. An auxiliary drug delivery structure 4 is arranged inside the conductive liquid supply structure 2. A disinfection structure 6 is movably connected to the outer surfaces of the driving structure 3 and the disinfection and cleaning structure 5.

[0037] During the operation of this embodiment, first take out the present invention from the disinfection structure 6 through the handle 1 and place it on the patient's chest. Push the disinfection and cleaning structure 5 forward and push it forward. Disinfect the patient's chest through the disinfection and cleaning structure 5. At the same time, use the cooperation of the driving structure 3 and the conductive liquid supply structure 2 to make the conductive liquid fall on the patient's chest, and level the conductive liquid falling on the patient's chest through the action of the auxiliary drug delivery structure 4, so as to ensure the uniformity of the conductive liquid and improve the accuracy of electrocardiogram monitoring;

[0038] After the detection is completed, pushing backward can use the auxiliary drug delivery structure 4 to scrape off the conductive liquid on the patient's skin and perform secondary cleaning and disinfection on the patient's chest through the disinfection and cleaning structure 5, reducing the residue of the conductive liquid on the patient's skin and keeping the skin of the patient's chest clean.

[0039] Specifically, to drive the operation of the conductive liquid supply structure 2 following the smearing action, refer to Figure 2 and Figure 3 , the driving structure 3 includes a fixing frame 31 fixedly connected to the conductive liquid supply structure 2. A first transmission shaft 32 is rotatably connected to the upper part of the inner surface of the fixing frame 31, and the first transmission shaft 32 penetrates through the adjacent end of the conductive liquid supply structure 2 and extends into the inner cavity of the conductive liquid supply structure 2. A second transmission shaft 34 is rotatably connected to the lower part of the inner cavity of the fixing frame 31. The second transmission shaft 34 penetrates through the inner surface and extends to the outer surface of the fixing frame 31 on the side adjacent to the conductive liquid supply structure 2 and is fixedly connected to a friction wheel 35. A transmission belt 33 is wound around the outer surfaces of the first transmission shaft 32 and the second transmission shaft 34.

[0040] When the present invention is pushed to slide on the patient's chest through the handle 1, the friction between the friction wheel 35 and the patient's skin will drive the second transmission shaft 34 to rotate, and the second transmission shaft 34 will drive the first transmission shaft 32 to rotate synchronously through the action of the transmission belt 33.

[0041] Embodiment 2

[0042] Based on Embodiment 1, this embodiment uses the cooperation of the driving structure 3 with the one-way transmission assembly 25 and the crankshaft 26 to drive the crankshaft 26 to rotate when pushing forward, and thereby drive several piston columns 23 on the crankshaft 26 to move up and down. Through the piston action of the piston columns 23 and the medicine delivery cavity 242, the conductive liquid in the medicine storage cavity 241 is extracted into the medicine delivery cavity 242 through the one-way valve assembly 243 and sent out through the rubber flap 244 to fall on the patient's skin, so as to realize automatic coating of the conductive liquid, reduce the manual operation of medical staff, reduce the contact between doctors and patients, and reduce the risk of cross-infection.

[0043] Specifically, to drive the movement of the piston columns 23 following the action of the driving structure 3, refer to Figure 3 , the conductive liquid supply structure 2 includes a fixing shell 21 fixedly connected to the lower end of the handle 1. The top wall of the inner cavity of the fixing shell 21 is symmetrically and fixedly connected with brackets 22 on the left and right. A crankshaft 26 is rotatably connected to the inner surfaces of the two brackets 22 together. Several piston columns 23 are rotatably connected to the outer surface of the crankshaft 26 in an alternating manner. One-way transmission assemblies 25 are arranged at the left and right ends of the crankshaft 26 and the inner cavities of the adjacent brackets 22. The ends of the two one-way transmission assemblies 25 away from each other are fixedly connected to the first transmission shaft 32 on the same side. A medicine storage and delivery assembly 24 is arranged between the bottom wall of the inner cavity of the fixing shell 21 and the outer surfaces of several piston columns 23. The rear part of the inner surface of the fixing shell 21 is rotatably connected to the auxiliary drug delivery structure 4.

[0044] During the rotation of the first drive shaft 32, it will drive the crankshaft 26 to rotate through the one-way drive assembly 25, and drive the piston rod 23 to slide up and down in the medicine storage and delivery assembly 24 through the cooperation of the crankshaft 26 and the piston rod 23; in addition, as Figure 1 and Figure 3 shown, the fixed housing 21 is provided with a liquid replenishing pipe communicating with the outside, and the fixed housing 21 can be replenished with conductive liquid through the liquid replenishing pipe.

[0045] Furthermore, to ensure that the piston rod 23 follows the movement of the driving structure 3 during forward pushing and the crankshaft 26 does not follow the movement of the driving structure 3 during backward pushing, refer to Figure 3 and Figure 4 The one-way drive assembly 25 includes a driving shaft 252 fixedly connected to the first drive shaft 32 on the same side. One end of the driving shaft 252 away from the first drive shaft 32 on the same side is rotatably connected to a driven shaft 251 rotatably connected to the inner surface of the bracket 22. The inner surface of the driven shaft 251 is rotatably connected to a driving wheel 253 fixedly connected to the driving shaft 252. Tooth segments 254 lapping with the driving wheel 253 are symmetrically rotatably connected to the upper and lower inner surfaces of the driven shaft 251. The outer arc surfaces of the two tooth segments 254 and the inner surface of the driven shaft 251 are fixedly connected with a reset reed together. One end of the driven shaft 251 away from the first drive shaft 32 on the same side is fixedly connected to the crankshaft 26.

[0046] When the first drive shaft 32 rotates, it will synchronously drive the driving shaft 252 fixedly connected to the first drive shaft 32 to rotate, and drive the driving wheel 253 to rotate through the action of the driving shaft 252. When pushing forward, the driving wheel 253 meshes with the tooth segments 254 and drives the driven shaft 251 to rotate through the driving wheel 253. The driven shaft 251 and the crankshaft 26 are fixedly connected together. When the driven shaft 251 rotates, it will synchronously drive the crankshaft 26 to rotate;

[0047] When pushing backward, the driving wheel 253 will push the tooth segments 254 outwards during rotation and will not drive the tooth segments 254 to rotate, thus realizing one-way power transmission.

[0048] Furthermore, to realize the movement following the driving structure 3 and cooperate with the piston rod 23 to send the conductive liquid to the patient's skin surface, refer to Figure 5 and Figure 6, the medicine storage and delivery assembly 24 includes a medicine storage cavity 241 fixed to the bottom wall of the inner cavity of the fixed housing 21. A number of limiting grooves 246 that are linearly distributed and slidably connected to the outer surface of the piston rod 23 are provided at the upper end of the medicine storage cavity 241. At the lower part of the inner surface of the medicine storage cavity 241, medicine outlets 247 corresponding to the piston rod 23 are linearly distributed. Rubber flap plates 244 are rotatably connected to the front and rear symmetry of the inner surface of the medicine outlet 247. At one side where the lower ends of the two rubber flap plates 244 are away from each other, reset reed pieces fixedly connected to the inner surface of the adjacent medicine outlet 247 are provided. At the upper part of the inner surface of the medicine outlet 247, a number of limiting blocks 245 that are fixedly connected and fit with the upper ends of the rubber flap plates 244 are rectangularly distributed. At the upper end of the medicine outlet 247, a delivery cavity 242 that is slidably connected to the piston head of the piston rod 23 is fixedly connected. At the lower part of the rear outer surface of the delivery cavity 242, a one-way valve assembly 243 is provided.

[0049] When the piston rod 23 slides upward in the delivery cavity 242 under the action of the crankshaft 26, the rubber flap plate 244 rotates upward under the action of the reed piece and is limited by the limiting block 245. The medicine outlet 247 is closed by the rubber flap plates 244 on both sides. At this time, when the piston rod 23 rises, a negative pressure will be formed in the delivery cavity 242, and the conductive liquid in the medicine storage cavity 241 will be pressed into the delivery cavity 242 through the one-way valve assembly 243. When the piston rod 23 descends in the delivery cavity 242, the one-way valve assembly 243 resets, the rubber flap plate 244 compresses the reed piece under the action of pressure and rotates downward, and the conductive liquid falls on the patient's skin through the medicine outlet 247, realizing automatic medicine supply.

[0050] Further, to achieve quantitative medicine intake, refer to Figure 6 and Figure 7 , the one-way valve assembly 243 includes a fixed pipe 2431 fixedly connected to the outer surface of the delivery cavity 242. The inner cavity of the fixed pipe 2431 is communicated with the inner cavity of the delivery cavity 242. A limiting plate 2434 is fixedly connected to the inner surface of the fixed pipe 2431. A first limiting rod 2432 is slidably connected to the inner surface of the limiting plate 2434. The front end of the vertical part of the first limiting rod 2432 extends into the inner cavity of the delivery cavity 242 and is fixedly connected with a blocking pad 2436 that fits with the inner surface of the delivery cavity 242. The front end of the horizontal part of the first limiting rod 2432 and the rear end of the limiting plate 2434 are jointly fixedly connected with a second compression spring 2433. A number of medicine inlet holes 2435 are annularly distributed on the front outer surface of the fixed pipe 2431.

[0051] When the piston rod 23 rises, due to the action of the rubber flap plate 244 and the limiting block 245, the medicine outlet 247 is closed, and a negative pressure is formed in the delivery cavity 242. At this time, the liquid medicine in the medicine storage cavity 241 will enter the delivery cavity 242 by pushing open the blocking pad 2436 through the medicine inlet holes 2435 and the fixed pipe 2431. Since the undulating stroke of the piston rod 23 is certain, the medicine intake is also a fixed value;

[0052] After the pressures in the medicine storage cavity 241 and the medicine delivery cavity 242 tend to balance, the medicine inlet pressure can no longer support the barrier pad 2436. Under the action of the first limiting rod 2432 and the second compression spring 2433, the barrier pad 2436 resets to isolate the fixed tube 2431 from the inner cavity of the medicine delivery cavity 242.

[0053] Embodiment III

[0054] On the basis of Embodiment II, in this embodiment, the conductive liquid that falls on the patient's skin surface through the medicine outlet 247 is leveled by using the limitation of the first limiting post 42 and the second limiting post 43 on the scraping plate 41 and the function of the scraping plate 41, so that the conductive liquid on the patient's skin surface is evenly distributed, avoiding the influence of uneven conductive liquid thickness on the signal conduction efficiency during detection and reducing the influence of the conductive liquid uniformity on the detection accuracy; at the same time, the conductive liquid on the patient's skin surface is scraped off by the function of the scraping plate 41 after the detection is completed, keeping the patient's skin dry and clean.

[0055] Specifically, to achieve the leveling and scraping of the conductive liquid, refer to Figure 8 , the auxiliary medicine delivery structure 4 includes a scraping plate 41 rotatably connected to the lower part of the inner surface of the fixed shell 21. The scraping plate 41 is located behind the medicine outlet 247. The left and right symmetrical parts of the inner surface of the fixed shell 21 in front of the scraping plate 41 are fixedly connected with the second limiting posts 43 that are in close contact with the front end of the scraping plate 41, and the left and right symmetrical parts of the inner surface of the fixed shell 21 behind the scraping plate 41 are fixedly connected with the first limiting posts 42.

[0056] When applying the conductive liquid, the conductive liquid falling from the medicine outlet 247 drops onto the patient's skin. At this time, the scraping plate 41 moves forward with the fixed shell 21 and contacts the conductive liquid. Under the action of the resistance, the scraping plate 41 rotates backward and contacts the first limiting post 42. Under the limitation of the first limiting post 42, the scraping plate 41 will move forward at a certain distance from the patient's skin and push the conductive liquid falling from the medicine outlet 247 forward with a certain thickness, so that the conductive liquid is evenly applied to the patient's skin surface;

[0057] When scraping off the conductive liquid, at this time, the crankshaft 26 no longer rotates. During the process of the scraping plate 41 moving backward with the fixed shell 21, it will be in close contact with the patient's skin surface under the action of the second limiting post 43, scrape the conductive liquid on the patient's skin surface onto the scraping plate 41, and fall into the disinfection structure 6 when the scraping plate 41 enters the disinfection structure 6.

[0058] Furthermore, to avoid damaging the patient's skin and ensure that the scraping plate 41 fits the patient's skin during scraping, refer to Figure 8 , the scraping plate 41 is a latex plate, the lower part of the front end of the scraping plate 41 is arc-shaped, and the lower part of the rear end is flat.

[0059] The front part of the squeegee 41 can evenly distribute the conductive liquid on the patient's skin surface. When moving in the reverse direction, the flat part of the squeegee 41 can scrape off the conductive liquid on the patient's skin surface. Using a latex plate can avoid scratching the patient while fitting with the patient's surface, reducing the patient's resistance.

[0060] Embodiment 4

[0061] Based on Embodiment 3, in this embodiment, the cleaning roller 52 is used to disinfect and clean the patient's skin. At the same time, the cooperation of the slider 55 and the first compression spring 56 makes the disinfection and cleaning structure 5 located below the driving structure 3 when not in use, which is convenient for storage. And through the function of the wedge-shaped channel 62, the waste conductive liquid on the squeegee 41 is guided to fall into the waste box 63 for storage. At the same time, the disinfection box 61 and the cleaning box 64 can clean the driving structure 3 and the disinfection and cleaning structure 5, and supplement the disinfectant on the surface of the cleaning roller 52 during the cleaning process, reducing the manual operation of medical staff and improving the detection efficiency.

[0062] Specifically, to achieve the disinfection and cleaning of the patient's skin surface, refer to Figure 9 and Figure 10 , the disinfection and cleaning structure 5 includes a fixed shaft 53 fixedly connected to the driving structure 3 on the same side. A second limiting rod 54 is fixedly connected to the inner surface of the fixed shaft 53. A slider 55 is slidably connected to the outer surface of the second limiting rod 54. One end of the slider 55 and the inner surface of the fixed shaft 53 close to each other are fixedly connected with a first compression spring 56. A connecting rod 51 is fixedly connected to the outer arc surface of the slider 55. The connecting rods 51 on both sides are fixedly connected with a cleaning roller 52 at the ends far from the driving structure 3.

[0063] Specifically, to achieve the cleaning and disinfection of the driving structure 3 and the disinfection and cleaning structure 5, refer to Figure 11 , the disinfection structure 6 includes a disinfection box 61. The lower end of the disinfection box 61 is fixedly connected with a cleaning box 64. The rear end of the cleaning box 64 and the rear end of the disinfection box 61 are fixedly connected with a waste box 63. A wedge-shaped channel 62 communicating with the lower part of the inner cavity of the disinfection box 61 is opened in the front part of the inner cavity of the waste box 63.

[0064] It should be noted that disinfection devices are provided inside the above-mentioned disinfection box 61 and cleaning box 64, which can disinfect and sterilize the surface of the driving structure 3 and the cleaning roller 52 through ultraviolet rays and high temperatures. The disinfection principle and the structure used are common knowledge, and the specific structure is not described in detail in the present invention.
