Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an ultrasound contrast injection device. Background Art

[0002] In recent years, it has been found that unexplained headaches, TIA, syncope on exertion, transient aphasia, sleep apnea, supine dyspnea, and orthostatic hypoxia syndrome may be related to potential abnormal channels between the left and right atria, ventricles, or systemic and pulmonary circulations, most commonly patent foramen ovale (PFO). Currently, PFO is mainly diagnosed through three methods: transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and TCD transcranial Doppler bubble test. Among them, TCD transcranial Doppler bubble test is widely used in clinical practice due to its advantages of being non-invasive, safe, and reliable.

[0003] When conducting a TCD transcranial Doppler bubble test on a human body, the subject will perform a Valsalva maneuver, which requires the subject to hold his breath and inflate his belly for a few seconds, and then immediately relax when prompted to do so. This maneuver is dangerous for patients with high blood pressure, and severe cases may experience headaches and fainting during the maneuver. However, currently, it is impossible to obtain the patient's blood pressure status in a timely manner while conducting a TCD transcranial Doppler bubble test, which makes the bubble test risky.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0037] See also Figure 1 and Figure 3An embodiment of the utility model provides an ultrasound contrast injection device 100, including a frame 10, a foaming component 20 and a blood pressure measurement component 30, wherein the foaming component 20 and the blood pressure measurement component 30 are both installed in the frame 10; the foaming component 20 is used to prepare and inject contrast agent, and the blood pressure measurement component 30 is used to measure blood pressure.

[0038] When in use, the blood pressure measurement component 30 performs blood pressure measurement while the foaming component 20 is working, monitors the blood pressure of the person to be measured in real time, or monitors and measures the blood pressure of the person to be measured at fixed intervals.

[0039] By adopting the above technical solution, on the one hand, by setting the foaming component 20 and the blood pressure measuring component 30, the foaming component 20 is used to make and inject contrast agent, and the blood pressure measuring component 30 is used to measure blood pressure, so that the ultrasound contrast injection device 100 can perform both foaming test and blood pressure monitoring. On the other hand, since the foaming component 20 and the blood pressure measuring component 30 are both arranged on the frame 10, the integration of the foaming component 20 and the blood pressure measuring component 30 is improved, and it is also conducive to improving the space utilization rate of the frame 10, so that the ultrasound contrast injection device integrating the two functions will not be too large, and it is convenient to be placed in the examination room with limited space for use, which greatly saves the space in the examination room.

[0040] See also Figures 4 to 6 The foaming assembly 20 includes a foaming mechanism 21, a driving mechanism 22 and a transmission mechanism 23. The transmission mechanism 23 is connected between the driving mechanism 22 and the foaming mechanism 21. The driving mechanism 22 is used to drive the foaming mechanism 21 to make and inject contrast agent.

[0042] It should be noted that the limitations of directional words such as top, bottom, up, and down in the present application are for ease of understanding. The description made when the ultrasound contrast injection device 100 is in use is only used to reflect the relative position relationship between the structures. When the ultrasound contrast injection device 100 is in other postures, the directional words in the present application should be understood after switching to the use state.

[0043] See also Figure 1 , Figure 3 and Figure 7 The measuring unit 31 includes an air pump 311, an electromagnetic valve 312, a pressure sensor 313 and a first circuit board 314, and the air pump 311, the electromagnetic valve 312 and the pressure sensor 313 are all arranged on the first circuit board 314 and are electrically connected to the first circuit board 314; the first air duct 32 includes an air main pipe 321, a first branch pipe 322 and a second branch pipe 323, and the first branch pipe 322 and the second branch pipe 323 are both interconnected with the air main pipe 321; the first branch pipe 322 and the second branch pipe 323 are both connected to the same end of the air main pipe 321, and the other end of the air main pipe 321 is used to connect with the blood pressure measurement cuff 50; the end of the first branch pipe 322 away from the air main pipe 321 is used to connect with the air pump 311 and the electromagnetic valve 312, and the end of the second branch pipe 323 away from the air main pipe 321 is used to connect with the pressure sensor 313. The air pump 311 , the solenoid valve 312 and the pressure sensor 313 are all mounted on the first circuit board 314 .

[0044] When performing blood pressure testing, the solenoid valve 312 is closed and the air pump 311 is opened. The air pump 311 can deliver gas to the blood pressure measurement cuff 50 through the first branch pipe 322 and the gas main pipe 321, and the second branch pipe 323 connects the gas main pipe 321 and the pressure sensor 313, so that the pressure sensor 313 can detect the cuff pressure and realize blood pressure testing; when the blood pressure test is completed, the solenoid valve 312 is opened, the air pump 311 is closed, and the solenoid valve 312 can release the gas in the blood pressure measurement cuff 50 through the first branch pipe 322 and the gas main pipe 321.

[0045] In this embodiment, two solenoid valves 312 and two pressure sensors 313 are provided. Thus, when one of the solenoid valves 312 or one of the pressure sensors 313 fails, the other solenoid valve 312 and the other pressure sensor 313 can still work normally, thereby ensuring that the measuring unit 31 can work normally; in addition, by providing two solenoid valves 312, the gas in the blood pressure measuring cuff 50 can be released faster after the blood pressure test is completed.

[0046] See also Figure 1 , Figure 4 and Figure 5The frame 10 includes a bottom plate 11 and a support frame 12. The support frame 12 is arranged on the bottom plate 11 and encloses with the bottom plate 11 to form a receiving space 13. The foaming mechanism 21, the driving mechanism 22 and the transmission mechanism 23 are all installed on the bottom plate 11, and the driving mechanism 22 and / or the transmission mechanism 23 are accommodated in the receiving space 13. The measuring unit 31 is arranged above the support frame 12. In this arrangement, on the one hand, by arranging the measuring unit 31 above the support frame 12 and accommodating the driving mechanism 22 and / or the transmission mechanism 23 in the receiving space 13 enclosed by the support frame 12 and the bottom plate 11, the measuring unit 31, the support frame 12 and the driving mechanism 22 and / or the transmission mechanism 23 are arranged in the frame with the smallest occupied area, which greatly reduces the volume of the ultrasound contrast injection device 100. On the other hand, the support frame 12 supports the measuring unit 31, which is conducive to improving the installation stability of the measuring unit 31.

[0047] In the embodiment of the present utility model, please refer to Figures 1 to 3 The frame 10 also includes a shell 14, which is connected to the circumference of the base plate 11 and encloses the base plate 11 to form a receiving cavity (not shown in the figure), and the foaming component 20 and the blood pressure measurement component 30 are both received in the receiving cavity; one end of the first air duct 32 away from the measuring unit 31 extends to the side of the foaming mechanism 21 and is connected to the shell 14.

[0048] One end of the first air duct 32 is connected to the measuring unit 31, and the other end of the first air duct 32 is connected to the part of the housing 14 near the foaming mechanism 21. In this way, the blood pressure measurement cuff 50 can be connected to the measuring unit 31 by being connected to the first air duct 32 located at the part of the housing 14 near the foaming mechanism 21. The foaming mechanism 21 uses physiological saline when performing a foaming test. The physiological saline bottle 200 for storing physiological saline is usually arranged near the foaming mechanism 21, which can reduce the length of the pipeline used for extracting physiological saline. At the same time, the other end of the first air duct 32 is connected to the part of the housing 14 near the foaming mechanism 21, so that the other end of the first air duct 32 is arranged near the physiological saline bottle 200. In this way, the operator can install or unload the physiological saline bottle 200 at the same operating position, and connect or disconnect the blood pressure measurement cuff 50 and the first air duct 32, which is convenient for the operator's operation.

[0049] See also Figures 2 to 4The shell 14 includes a main body 141 and a transparent part 142; the main body 141 is connected to the circumference of the bottom plate 11, and the first air duct 32 is connected to the main body 141; the transparent part 142 is movably connected to the main body 141, and is arranged corresponding to the foaming mechanism 21. Through the transparent part 142, the operator can observe the situation in the foaming mechanism 21, such as checking the state of the liquid in the foaming mechanism 21, so that the operator can understand whether the current state of contrast agent production or injection is normal, thereby determining whether it is necessary to continue or stop the production or injection of contrast agent.

[0050] The ultrasound contrast injection device 100 further includes a flip assembly 40, which is connected to the transparent portion 142 and is used to drive the transparent portion 142 to rotate relative to the main portion 141 to open or close a portion of the receiving cavity. When the operator needs to manually operate the foaming mechanism 21, the flip assembly 40 can drive the transparent portion 142 to rotate relative to the main portion 141 to open a portion of the receiving cavity to facilitate the operator to operate; when the operator does not need to operate the foaming mechanism 21, the flip assembly 40 can drive the transparent portion 142 to rotate relative to the main portion 141 to close a portion of the receiving cavity.

[0051] It should be noted that the above-mentioned opening or closing of part of the receiving cavity refers to opening or closing the receiving cavity portion corresponding to the transparent portion 142, while opening or closing the entire receiving cavity refers to opening or closing the receiving cavity portion corresponding to the outer shell 14, that is, the receiving cavity portion corresponding to the main body 141 and the transparent portion 142.

[0052] In the embodiment of the utility model, the flip assembly 40 is arranged above the transmission mechanism 23, and the blood pressure measurement assembly 30 is arranged above the drive mechanism 22. It can be understood that the flip assembly 40 can also be arranged above the drive mechanism 22, and the blood pressure measurement assembly 30 can also be arranged above the transmission mechanism 23.

[0053] In the embodiment of the utility model, the support frame 12 is fixed to the base plate 11 by four M3-6 screws and is located above the driving mechanism 22, so that the free space at this position is reasonably utilized. When installing the measuring unit 31, four M3 copper studs are screwed on the support frame 12, and four through holes are provided on the first circuit board 314. The four M3 copper studs of the support frame 12 are aligned, and four M3-5 screws are screwed downward from the top of the measuring unit 31 to fix the M3-5 screws to achieve the installation of the measuring unit 31. The entire structure adds a dynamic blood pressure monitoring function without increasing the size of the ultrasound contrast injection device 100.

[0054] See also Figure 1 and Figure 3, the ultrasound contrast injection device 100 also includes a blood pressure measurement cuff 50 and a second airway tube 60, one end of the second airway tube 60 is connected to the blood pressure measurement cuff 50, and the other end is connected to the first airway tube 32, so as to connect the blood pressure measurement cuff 50 and the first airway tube 32. In this way, the person to be tested can also have his blood pressure measured at a location far away from the host of the ultrasound contrast injection device 100. Of course, in a specific application, as an alternative implementation scheme, the ultrasound contrast injection device 100 is not provided with the second airway tube 60, and the blood pressure measurement cuff 50 is directly connected to the first airway tube 32. Among them, the host of the ultrasound contrast injection device 100 refers to the sum of the components of the ultrasound contrast injection device 100 except the blood pressure measurement cuff 50 and the second airway tube 60.

[0055] In the embodiment of the utility model, the second airway tube 60 is detachably connected to the first airway tube 32. In this way, the second airway tube 60 can be separated from the first airway tube 32. By disassembling the second airway tube 60, the blood pressure measurement cuff 50 can be disassembled, which is conducive to the replacement or cleaning of the blood pressure measurement cuff 50; in addition, the second airway tube 60 and the blood pressure measurement cuff 50 can also be disassembled during transportation to facilitate the transportation of the device. It can be understood that the second airway tube 60 and the first airway tube 32 can also be fixedly connected.

[0056] See also Figure 1 , Figure 3 and Figure 8 The ultrasound contrast injection device 100 also includes a first airway joint 71 and a second airway joint 72; the first airway joint 71 is connected to the end of the first airway tube 32 away from the measuring unit 31, and is installed on the frame 10, so that the end of the first airway tube 32 away from the measuring unit 31 can be installed on the frame 10; the second airway joint 72 is connected to the end of the second airway tube 60 away from the blood pressure measurement cuff 50, and the first airway joint 71 and the second airway joint 72 are detachably connected to each other. By setting the first airway joint 71 and the second airway joint 72, the first airway tube 32 and the second airway tube 60 are connected and detachably connected. Among them, the first airway joint 71 can be set as a male joint, and the second airway joint 72 can be set as a female joint.

[0057] See also Figure 1 , Figure 3 , Figure 4 and Figure 7The ultrasound contrast injection device 100 further includes a second circuit board 80, and the foaming component 20 and the blood pressure measuring component 30 are both electrically connected to the second circuit board 80. The foaming component 20 and the blood pressure measuring component 30 can be controlled to work by the control chip on the second circuit board 80. In the embodiment of the utility model, the first circuit board 314 is electrically connected to the second circuit board 80, and the first circuit board 314 can also feed back the cuff pressure to the control chip on the second circuit board 80.

[0058] See also Figure 1 and Figure 4 The ultrasound contrast injection device 100 also includes a display screen 90, which is electrically connected to the second circuit board 80. The display screen 90 can be used to display the cuff pressure for the convenience of the operator to view.

[0059] When the foaming component 20 starts working, the blood pressure measuring component 30 works synchronously. The subject wears the blood pressure measuring cuff 50 to measure the blood pressure. The blood pressure measuring component 30 measures the blood pressure every few minutes, and the measurement results are displayed on the display screen 90. Medical staff can monitor the changes in the subject's blood pressure at any time. Of course, the foaming component 20 and the blood pressure measuring component 30 can also work asynchronously. For example, when the foaming component 20 stops working, if the doctor needs to measure the subject's blood pressure again, the blood pressure measurement function can be turned on separately to measure the blood pressure.

[0060] The ultrasound contrast injection device 100 provided in the embodiment of the utility model, on the one hand, by providing a foaming component 20 for making and injecting contrast agent, and providing a blood pressure measuring component 30 for measuring blood pressure, the ultrasound contrast injection device 100 can perform both a foaming test and blood pressure monitoring. On the other hand, since both the foaming component 20 and the blood pressure measuring component 30 are provided in the frame, the integration of the foaming component 20 and the blood pressure measuring component 30 is improved, and the space utilization rate of the frame 10 is also improved, so that the volume of the ultrasound contrast injection device integrating the two functions is not too large.

[0061] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
