TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a device for automatically performing a bubble test. BACKGROUND

[0002] Cardiac contrast acoustic is divided into left atrial bubble test and right atrial bubble test. Among them, the indications of right atrial bubble test include: 1) patent foramen ovale (PFO) screening; 2) diagnosis of congenital vascular malformations such as persistent left superior vena cava, pulmonary arteriovenous fistula, etc.; 3) evaluation of right heart lumen diameter, endocardial boundary profile, ventricular wall thickness, presence of space-occupying lesions and valve regurgitation, etc.; 4) finding the cause for hypoxemia patients. Therefore, the right atrial bubble test can be used for auxiliary screening and detection of many diseases. The indications of left atrial bubble test include: 1) coronary heart disease; 2) heart failure; 3) intracardiac mass; 4) auxiliary judgment of hypertrophic cardiomyopathy and other cardiac structural abnormalities. Therefore, the left atrial bubble test can also be used for auxiliary screening and detection of many diseases.

[0003] For the left atrial bubble test, physiological saline is mixed with powdered contrast agent to obtain left atrial microbubble contrast agent, which is then injected into the human body for subsequent tests. For the left atrial bubble test, medical personnel manually inject physiological saline into a container containing the contrast agent to dissolve the contrast agent in the physiological saline to obtain a mixed solution. Then, the mixed solution is repeatedly extracted and injected by a syringe to prepare the microbubble contrast agent contained in the container. When injecting, the microbubble contrast agent is extracted from the container by the syringe and then injected into the patient's body from the patient's vein.

Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0060] Reference will now be made to Figures 1-3As shown, the present application provides a device 100 for automatically performing a foaming test, the device 100 comprising a pipeline 120, a second valve 140, a third valve 150, a first syringe 160 and a second syringe 170.

[0061] The pipeline 120 has a first end 121 and a second end 122 oppositely arranged, the first end 121 is used for connecting to the first container 101, and the second end 122 is used for connecting to an external indwelling needle.

[0062] Further, the first container 101 is used for containing a contrast mixture, the contrast mixture is prepared by mixing physiological saline and powdered contrast agent. The contrast mixture is used for left atrial contrast detection after foaming to form a foaming liquid.

[0063] The powdered contrast agent is contained in the first container 101, and the medical staff can push physiological saline into the first container 101 through the syringe to dissolve the contrast agent in the physiological saline to form the contrast mixture.

[0064] Preferably, the medical staff can repeatedly draw and inject the contrast mixture through the syringe to fully dissolve the contrast agent in the physiological saline and obtain a uniformly mixed contrast mixture; or the medical staff can also shake the first container 101 to fully dissolve the contrast agent in the physiological saline and obtain a uniformly mixed contrast mixture.

[0065] The first syringe 160 and the second syringe 170 are respectively used for performing the push and draw actions.

[0066] The second valve 140 is arranged on the pipeline 120, and the second valve 140 has at least three interfaces, two of which are used for connecting the pipeline 120, and at least one of the other interfaces is used for connecting to the first syringe 160.

[0067] The third valve 150 is arranged on the pipeline 120, and the third valve 150 has at least three interfaces, two of which are used for connecting the pipeline 120, and at least one of the other interfaces is used for connecting to the second syringe 170.

[0068] Further, the second valve 140 and the third valve 150 are sequentially arranged in the direction from the first end 121 to the second end 122. That is to say, the second valve 140 is connected to the pipeline 120 between the first end 121 and the third valve 150, and the third valve 150 is connected to the pipeline 120 between the second valve 140 and the second end 122.

[0069] Further, the device 100 has a left atrial contrast working mode, in which the device 100 has a switchable plurality of pipeline 120 states, so that the device 100 can automatically complete the preparation of the left atrial foaming liquid.

[0070] Furthermore, please refer to Figures 1-3 As shown, in the first embodiment, when the device 100 is switched to the first pipeline 120 state, the second valve 140 is configured to connect the liquid path between the first container 101 and the first syringe 160, and the second valve 140 also closes the pipeline 120 between the first syringe 160 and the third valve 150, so as to control the first syringe 160 to draw the contrast mixture from the first container 101.

[0071] After the first syringe 160 completes the extraction of the contrast mixture, the device 100 will switch to the second pipeline 120 state. At this time, the second valve 140 and the third valve 150 are set to connect the liquid path between the first syringe 160 and the second syringe 170, and the second valve 140 closes the pipeline 120 between the first syringe 160 and the first container 101, and the third valve 150 closes the pipeline 120 between the second syringe 170 and the second end 122.

[0072] Then, the first syringe 160 and the second syringe 170 work together to repeatedly inject the contrast mixture between the first syringe 160 and the second syringe 170 until bubble fluid is formed. In this way, the resistance of the contrast mixture reciprocating between the first syringe 160 and the second syringe 170 is reduced by the cooperation of the first syringe 160 and the second syringe 170, the efficiency of injecting the contrast mixture is improved, and the time for the contrast mixture to form bubble fluid is shortened. This allows the contrast mixture to quickly form bubble fluid in the second tubing 120 state, completing the automatic preparation of left atrial contrast bubble fluid, thereby improving the preparation efficiency and consistency of bubble fluid.

[0073] Furthermore, compared to using only one syringe to inject and extract the contrast mixture, this embodiment uses the first syringe 160 and the second syringe 170 to work together to repeatedly inject the contrast mixture, which can effectively reduce the resistance of the contrast mixture when it reciprocates between the first syringe 160 and the second syringe 170, thereby further improving the efficiency of bubble solution preparation.

[0074] Furthermore, after the foaming solution is prepared, it will be injected into the patient's body through an indwelling needle via a vein, and a left atrial foaming test will be performed.

[0075] Preferably, in the state of the second tubing 120, the first syringe 160 and the second syringe 170 cooperate to inject back and forth at least 20 times, so that the contrast mixture can form a foaming solution with good consistency.

[0076] Further, the foaming liquid can be injected into the patient through the indwelling needle from the patient's vein by the first syringe 160, or can be injected into the patient through the indwelling needle from the patient's vein by the second syringe 170.

[0077] Preferably, the foaming liquid is injected into the patient through the indwelling needle from the patient's vein by the second syringe 170, so as to shorten the travel distance of the foaming liquid before entering the patient's body.

[0078] Further, please refer to Figures 2-4 As shown in the second embodiment, before the device 100 is switched to the first state of the pipeline 120, the device 100 is first switched to the third state of the pipeline 120. At this time, the second valve 140 is set to connect the liquid path between the second container 110 and the first syringe 160, and the second valve 140 is also set to close the pipeline 120 between the first syringe 160 and the third valve 150, so as to control the first syringe 160 to extract the physiological saline from the second container 110.

[0079] After the first syringe 160 completes the extraction of the physiological saline, the device 100 is switched to the fourth state of the pipeline 120. At this time, the second valve 140 is set to connect the liquid path between the first container 101 and the first syringe 160, and the second valve 140 is also set to close the pipeline 120 between the first syringe 160 and the third valve 150, so as to control the first syringe 160 to inject the extracted physiological saline into the first container 101, so that the contrast agent collected in the first container 101 is mixed with the physiological saline to obtain a contrast mixed liquid.

[0080] In the embodiment, the switching of the second end 122 from being in communication with the second container 110 in the third state of the pipeline 120 to being in communication with the first container 101 in the fourth state of the pipeline 120 can be manually operated by medical personnel. Compared with the first embodiment described above, the embodiment does not require medical personnel to pre-mix the contrast agent with the physiological saline, further reducing the workload of medical personnel, and effectively improving the precision control of the amount of physiological saline taken under automatic operation.

[0081] Further, please refer to Figures 5-6 As shown in the third embodiment, the pipeline 120 includes a first sub-pipeline 123 and a second sub-pipeline 124. The first sub-pipeline 123 has opposite first and second ends 121 and 122, and the second sub-pipeline 124 has opposite third and fourth ends 125 and 126. The fourth end 126 is used to be connected to the second container 110, and the second container 110 is used to collect physiological saline.

[0082] The device 100 further comprises a first valve 130 having at least three interfaces, two of which are used to communicate the first sub-pipe 123 and are located between the first end 121 and the second valve 140, and at least one other interface is used to communicate to the third end 125.

[0083] Further, in the left atrial angiography working mode, the device 100 has switchable multiple pipe 120 states.

[0084] When the device 100 is switched to the third pipe 120 state, the first valve 130 and the second valve 140 are respectively arranged to communicate the liquid path between the second container 110 and the first syringe 160, and the first valve 130 is simultaneously closed to the pipe 120 between the first valve 130 and the first container 101, and the second valve 140 is simultaneously closed to the pipe 120 between the first syringe 160 and the third valve 150, so as to control the first syringe 160 to draw physiological saline from the second container 110.

[0085] After the first syringe 160 completes the drawing of physiological saline, the device 100 is switched to the fourth pipe 120 state, at this time, the first valve 130 and the second valve 140 are respectively arranged to communicate the liquid path between the first container 101 and the first syringe 160, and the first valve 130 is simultaneously closed to the second sub-pipe 124, and the second valve 140 is simultaneously closed to the pipe 120 between the first syringe 160 and the third valve 150, so as to control the first syringe 160 to inject the drawn physiological saline into the first container 101, so that the contrast agent and the physiological saline mixed in the first container 101 obtain a contrast mixed liquid.

[0086] Further, the device 100 is switched to the first pipe 120 state, at this time, the first valve 130 and the second valve 140 are respectively arranged to communicate the liquid path between the first container 101 and the first syringe 160, and the first valve 130 is simultaneously closed to the second sub-pipe 124, and the second valve 140 is simultaneously closed to the pipe 120 between the first syringe 160 and the third valve 150, so as to control the first syringe 160 to draw the contrast mixed liquid from the first container 101.

[0087] After the first syringe 160 completes the drawing of the contrast mixed liquid, the device 100 is switched to the second pipe 120 state, at this time, the second valve 140 and the third valve 150 are arranged to communicate the liquid path between the first syringe 160 and the second syringe 170, and the second valve 140 is closed to the pipe 120 between the first syringe 160 and the first valve 130, and the third valve 150 is closed to the pipe 120 between the second syringe 170 and the second end 122.

[0088] Then, the first syringe 160 and the second syringe 170 are cooperated to reciprocally push the contrast mixture liquid between the first syringe 160 and the second syringe 170 until the bubble liquid is formed.

[0089] Further, the third valve 150 is controlled to connect the second syringe 170 and the pipeline 120 before the indwelling needle, and the third valve 150 is simultaneously closed to shut the pipeline 120 between the second valve 140 and the third valve 150, and then the bubble liquid in the second syringe 170 is pushed to enter the patient intravenously through the indwelling needle.

[0090] In the embodiment, the first valve 130, the first sub-pipeline 123 and the second sub-pipeline 124 are arranged to connect the first container 101 and the second container 110 to the pipeline 120 respectively. Thus, the pipeline 120 between the first syringe 160 and the first container 101 is connected and the second sub-pipeline 124 is closed, and the pipeline 120 between the first syringe 160 and the second container 110 is connected and the pipeline 120 between the first valve 130 and the first container 101 is closed by controlling the first valve 130. Thus, the pipeline 120 between the first container 101 and the second container 110 is switched without the participation of the medical staff, and the left atrium bubble liquid is automatically prepared by the device 100.

[0091] Further, referring to FIG. 1, the device 100 further comprises a hanger 280. The first container 101 and the second container 110 are arranged on the hanger 280.

[0092] In one embodiment, the hanger 280 is shaken to drive the first container 101 to shake synchronously under the action of an external force, so that the contrast agent contained in the first container 101 is fully dissolved into the physiological saline to obtain the mixed contrast mixture liquid.

[0093] In another embodiment, the first container 101 is shaken to make the contrast agent fully dissolved into the physiological saline to obtain the mixed contrast mixture liquid under the action of an external force.

[0094] Further, the hanger 280 comprises a support arm 281, a first hanging arm 282 and a second hanging arm 283. The first hanging arm 282 is elastically swingably connected to the support arm 281, the first container 101 is arranged on the first hanging arm 282, and the first hanging arm 282 drives the first container 101 to shake synchronously relative to the support arm 281 under the action of an external force, so that the contrast agent contained in the first container 101 is fully dissolved into the physiological saline to obtain the mixed contrast mixture liquid. The second container 110 is arranged on the second hanging arm 283.

[0095] ​Alternatively, the first container 101 is driven to swing synchronously relative to the support arm 281 under the action of an external force (e.g. a medical staff member using a hand to push), so that the contrast agent contained in the first container 101 is fully dissolved into the physiological saline and a mixed contrast solution is obtained.

[0096] Further, the first hanging arm 282 is a resilient arm, so that the first hanging arm 282 can be elastically swung under the action of an external force and drive the first container 101 to swing synchronously; alternatively, an elastic member is arranged between the first hanging arm 282 and the support arm 281, and the elastic member can be a spring, a spring piece or other structural member that can be elastically deformed under an external force.

[0097] Preferably, the first hanging arm 282 clamps the first container 101, so that the first container 101 is inverted on the hanger 280.

[0098] Further, the device 100 can further include a driving mechanism for driving the hanger 280 or the first container 101 to swing so that the contrast agent is fully dissolved into the physiological saline to form a mixed contrast solution.

[0099] Specifically, the driving mechanism can drive the first container 101 to swing relative to the hanger 280, or drive the hanger 280 to swing and drive the first container 101 to swing synchronously, or drive the first hanging arm 282 to swing relative to the support arm 281 and drive the first container 101 to swing synchronously.

[0100] Further, in other embodiments, the first syringe 160 can also be reciprocated to extract the bolus of the mixed contrast solution from the first container 101, so that the contrast agent is fully dissolved into the physiological saline to obtain a mixed contrast solution.

[0101] Further, please refer to Figures 8-9 As shown, the device 100 further includes a first valve 130 driving member, a second valve 140 driving member and a third valve 150 driving member. The first valve 130 driving member, the second valve 140 driving member and the third valve 150 driving member are all motors, the first valve 130 driving member is connected with the first valve 130 and used to switch the working state of the first valve 130, the second valve 140 driving member is connected with the second valve 140 and used to switch the working state of the second valve 140, and the third valve 150 driving member is connected with the third valve 150 and used to switch the working state of the third valve 150. The first valve 130 driving member, the second valve 140 driving member and the third valve 150 driving member are all electrically connected with a control system, and the control system is used to control the working mode of the first valve 130 driving member, the second valve 140 driving member and the third valve 150 driving member.

[0102] Further, the device 100 also has a right atrial contrast working mode. That is, the device 100 has both the left atrial contrast mode and the right atrial contrast mode which are switchable.

[0103] In the right atrial contrast working mode, the device 100 can switch different working modes of the pipeline 120. When the device 100 is switched to the first pipeline mode, the first valve 130 and the second valve 140 connect the liquid path between the second container 110 and the first syringe 160.

[0104] When the device 100 is switched to the second pipeline mode, the first valve 130, the second valve 140 and the third valve 150 connect the liquid path between the second container 110 and the second syringe 170.

[0105] When the device 100 is switched to the third pipeline mode, the first valve 130, the second valve 140 and the third valve 150 connect the liquid path between the external environment and the second syringe 170.

[0106] When the device 100 is switched to the fourth pipeline mode, the third valve 150 connects the liquid path between the second syringe 170 and the indwelling needle.

[0107] When the device 100 is switched to the fifth pipeline mode, the second valve 140 and the third valve 150 connect the liquid path between the first syringe 160 and the indwelling needle.

[0108] When the device 100 is switched to the sixth pipeline mode, the second valve 140 and the third valve 150 connect the liquid path between the first syringe 160 and the second syringe 170.

[0109] It should be noted that, for example, when the device 100 is switched to the first pipeline mode, the first valve 130 and the second valve 140 connect the liquid path between the second container 110 and the first syringe 160, at this time, the second valve 140 closes the interface connected with the indwelling needle.

[0110] For example, when the device 100 is switched to the second pipeline mode, the first valve 130, the second valve 140 and the third valve 150 connect the liquid path between the second container 110 and the second syringe 170, at this time, the third valve 150 closes the interface connected with the indwelling needle.

[0111] For another example, when the device 100 is switched to the fifth pipeline mode, the second valve 140 and the third valve 150 connect the liquid path between the first syringe 160 and the indwelling needle, at this time, the second valve 140 closes the interface connected with the second container 110. That is, when one of the pipelines 120 is connected, the interfaces of the valves connected with the remaining pipelines 120 are closed.

[0112] The first end 121 of the pipeline 120 in the device 100 of the present application is in communication with the second container 110 containing normal saline. Since the entire device 100 is automated, the device 100 can automatically draw normal saline during the bubble test.

[0113] In addition, the second container 110, the first valve 130, the first syringe 160 and the second syringe 170 are arranged in sequence along the pipeline 120 from the first end 121 to the second end 122. The second syringe 170 is used to inject the obtained bubble liquid (microbubble embolus contrast medium) into the human body. On the basis that the device 100 can automatically draw normal saline, after the second syringe 170 draws blood, the first syringe 160 can push the drawn normal saline into the human body to clean the pipeline and prevent blood from coagulating and blocking the pipeline.

[0114] In addition, after the bubble liquid in the second syringe 170 is injected into the human body, the second syringe 170 and the first syringe 160 inject normal saline into the human body in sequence, which can push the microbubble contrast medium into the human body as much as possible and also clean the pipeline. If the same patient needs to undergo multiple bubble tests, it does not affect the next bubble test.

[0115] In one embodiment, referring to Figures 8-12 As shown in the figure, the pipeline 120 is arranged along a straight line. In the present application, the pipeline 120 is arranged along a straight line, and the first syringe 160 and the second syringe 170 are arranged side by side, which can minimize the size of the device 100 and facilitate use.

[0116] In addition, the device 100 in the present application includes a first syringe driving member 180 and a second syringe driving member 190. The first syringe driving member 180 includes a connected first syringe driving member body and a first syringe driving member output end 181, and the first syringe driving member output end 181 is connected with the piston of the first syringe 160. The first syringe driving member body can drive the first syringe driving member output end 181 to move to drive the piston of the first syringe 160 to move.

[0117] The second syringe driving member 190 includes a connected second syringe 170 body and a second syringe driving member output end 191, and the second syringe driving member output end 191 is connected with the piston of the second syringe 170. The second syringe driving member body can drive the second syringe driving member output end 191 to move to drive the piston of the second syringe 170 to move.

[0118] Specifically, the first syringe driving member 180 and the second syringe driving member 190 are both screw modules. A position sensor is correspondingly arranged at the first syringe driving member output end 181 and the second syringe driving member output end 191, for sensing the movement position of the first syringe driving member output end 181 and the second syringe driving member output end 191, preventing over-movement and safety problems.

[0119] In an embodiment, the device 100 further comprises an air filter 200. The air filter 200 is in communication with one of the first valves 130, for purifying the air entering from the outside, ensuring that the foaming test is more safely carried out.

[0120] Referring to Figure 8 As shown, the device 100 further comprises a first ultrasonic bubble sensor 210. The first ultrasonic bubble sensor 210 is correspondingly arranged on the pipeline 120 between the second container 110 and the first valve 130, for monitoring whether there is a bubble when the physiological saline passes, to confirm whether the pipeline 120 is leaking.

[0121] Specifically, when the first syringe 160 and the second syringe 170 draw physiological saline, under normal circumstances, physiological saline is drawn, and when an abnormal situation occurs, such as poor sealing of the joint, leakage occurs, at this time, part of the air may be drawn, when the air passes through the pipeline corresponding to the first ultrasonic bubble sensor 210, the first ultrasonic bubble sensor 210 outputs a high level, and when the pipeline is filled with physiological saline, a low level is output, and the control system judges whether the passing is a bubble through the high and low level signals, when there is a bubble, the system will alarm and stop the next operation, thereby ensuring that the foaming injection device 100 can draw physiological saline.

[0122] Referring to Figure 8 As shown, the device 100 further comprises a second ultrasonic bubble sensor 220. The second ultrasonic bubble sensor 220 is correspondingly arranged on the pipeline 120 between the second syringe 170 and the indwelling needle, for monitoring whether there is air or a large bubble passing during the foaming liquid injection process or the physiological saline injection process, to ensure the safety of injection.

[0123] Specifically, when the foaming liquid is injected into the human body, the foaming liquid will flow through the position of the pipeline 120 corresponding to the second ultrasonic bubble sensor 220, at this time, if there is air or a large bubble passing, the second ultrasonic bubble sensor 220 will sense and output a low level signal to the control system, and the control system will alarm and take corresponding measures to ensure that the foaming liquid injected into the vein of the human body is safe and reliable. In the present application, the first ultrasonic bubble sensor 210 and the second ultrasonic bubble sensor 220 can also be replaced by visual, blood oxygen and other types of sensors.

[0124] Referring toFigure 9 As shown, the device 100 further comprises a blood oxygen detection sensor 230, which is arranged at a position between the second syringe 170 and the indwelling needle on the pipeline 120, for monitoring whether the blood passes through within a specified time when the blood is drawn, to ensure that the blood drawing process is safely carried out, and to prevent the second syringe 170 from forming negative pressure in the second syringe 170 due to the failure to draw blood, thereby causing harm to the equipment and the human body. In the present application, the blood oxygen detection sensor 230 can also be replaced by other types of sensors such as infrared sensors, visual sensors, etc.

[0125] As shown in Figure 9 The device 100 can further comprise a miniature camera 240. The miniature camera 240 is arranged corresponding to the second syringe 170, and the miniature camera 240 is used to take images of the foamed liquid to confirm the blood content and the number and size of microbubbles in the foamed liquid.

[0126] Specifically, the miniature camera 240 sends the pictures taken to the control system. On the one hand, the control system determines whether the second syringe 170 draws sufficient blood by the color and liquid level of the foamed liquid in the second syringe 170. If no blood is drawn, the liquid in the second syringe 170 is a mixture of physiological saline and air, and the color is slightly colorless, i.e., the miniature camera 240 is used to secondarily confirm whether the second syringe 170 draws blood. When the blood cannot be drawn or the amount of blood is insufficient, the number of microbubble emboli in the foamed liquid will be very small, and it is easy to break and produce large bubbles, which is not conducive to detection.

[0127] On the other hand, the control system calculates the number and size of microbubble emboli in the second syringe 170 shown in the picture (it should be noted that a large number of large pictures need to be given to the control system in the early stage for training, and the control system continuously learns, and finally the number and size of microbubbles can be fed back according to the pictures sent by the miniature camera 240), so as to make reference to the final inspection result. If the number of microbubble emboli is too small, the final inspection result can be inaccurate, and if the microbubble emboli is too large, the final inspection result can also be inaccurate.

[0128] As shown in Figure 11 The device 100 further comprises a thrust sensor. The thrust sensor at least comprises a first thrust sensor 250 and a second thrust sensor 260. The first thrust sensor 250 is arranged corresponding to the output end 181 of the first syringe driving member, and the first thrust sensor 250 is used to sense the injection thrust size of the output end 181 of the first syringe driving member when the foamed liquid is mixed or the physiological saline is injected into the human body by the first syringe 160, so as to ensure the safety of injection.

[0129] The second thrust sensor 260 is arranged corresponding to the second syringe driving member output end 191, and is used for sensing the injection thrust of the second syringe driving member output end 191 when the foaming liquid is mixed or the second syringe 170 injects the physiological saline into the human body, so as to ensure the safety of injection.

[0130] Specifically, during injection, the indwelling needle may be in contact with the blood vessel wall of the patient, causing the indwelling needle port to be blocked or the needle to run out, and at this time, the injection will cause the injection thrust to sharply rise, and if the injection continues, the blood vessel wall of the patient may be damaged or the elbow vein may be bulged, so when the thrust sensor detects that the injection thrust exceeds a certain range and continuously rises, the system alarms and stops injection to avoid hurting the patient. Subsequently, the position of the indwelling needle needs to be manually adjusted.

[0131] Referring to Figures 9-10 As shown in the drawings, the device 100 of the present application further comprises a dust cover device 270. The dust cover device 270 comprises a dust cover and a dust cover driving member, and the dust cover driving member is connected with the dust cover and is used for driving the dust cover to cover the parts where the air filter 200, the first syringe 160, the second syringe 170, the first valve 130, the second valve 140 and the third valve 150 are arranged.

[0132] Further, the device 100 has a boss, the lower end of the boss is provided with a motor of the valve, and the upper part of the boss is provided with the first syringe 160, the second syringe 170, the air filter 200, the first valve 130, the second valve 140, the third valve 150 and part of the pipeline 120, so as to save space, facilitate the installation and operation of the dust cover, and be beneficial to the miniaturization of the device 100.

[0133] In the device 100 of the present application, a plurality of monitoring devices 100 are arranged to maximize the safe performance of the foaming test, so that the doctor does not need to pay attention to the operation of the equipment at all times, and the doctor can use it with peace of mind, and the operation burden of the doctor is also reduced. The device 100 is highly automated and runs safely and efficiently.

[0134] Further, in the right atrial contrast mode, the working principle of the device 100 is as follows:

[0135] Preparation step: first, the foaming test device 100 switches to the first pipeline mode, the first syringe 160 extracts physiological saline from the second container 110; then the foaming test device 100 switches to the second pipeline mode, the second syringe 170 extracts physiological saline from the second container 110; the foaming test device 100 switches to the fourth pipeline mode, the second syringe 170 discharges physiological saline from the indwelling needle; finally, the foaming test device 100 switches to the fifth pipeline mode, the first syringe 160 discharges physiological saline from the indwelling needle; wherein, when the first syringe 160 and the second syringe 170 discharge physiological saline from the indwelling needle, the first syringe 160 and the second syringe 170 should be pushed to the bottom to exhaust the air in the first syringe 160 and the second syringe 170.

[0136] In the preparation step, when the first syringe 160 and the second syringe 170 extract physiological saline, the first ultrasonic bubble sensor 210 monitors whether there are bubbles when the physiological saline passes, if there are bubbles, an alarm is given, and the pipeline 120 is checked for leaks.

[0137] Mixed solution extraction step: first, the foaming test device 100 switches to the first pipeline mode, the first syringe 160 extracts physiological saline from the second container 110; second, the foaming test device 100 switches to the second pipeline mode, the second syringe 170 extracts physiological saline from the second container 110; third, the foaming test device 100 switches to the third pipeline mode, the second syringe 170 extracts air from the outside; fourth, the foaming test device 100 switches to the fourth pipeline mode, the second syringe 170 extracts blood from the human body through the indwelling needle to obtain the mixed solution, in this step, the blood oxygen detection sensor 230 monitors whether there is blood passing within a specified time, if not, an alarm is given; fifth, the foaming test device 100 switches to the fifth pipeline mode, the first syringe 160 injects physiological saline into the human body, in this step, the second ultrasonic bubble sensor 220 monitors whether there are large bubbles or air when the foaming liquid passes, if so, the system alarms, and the equipment is adjusted later to ensure the safety of the foaming liquid injected into the human body vein; at the same time, the first thrust sensor 250 senses the thrust of the output end 181 of the first syringe driving member, if the thrust continues to rise within a certain range, an alarm is given, and the indwelling needle is adjusted manually later. In addition, in the first and second steps, when the first syringe 160 and the second syringe 170 extract physiological saline, the first ultrasonic bubble sensor 210 monitors whether there are bubbles when the physiological saline passes, if there are bubbles, an alarm is given, and the pipeline 120 is checked for leaks.

[0138] Foaming liquid preparation step: the foaming test device 100 switches to the sixth pipeline mode, the first syringe 160 and the second syringe 170 reciprocally inject the mixed liquid, the sum of the injection times of the first syringe 160 and the second syringe 170 is an even number (the purpose is to make the foaming liquid be injected into the human body through the second syringe 170), and is at least 20 times or more, to obtain the foaming liquid.

[0139] In this step, the micro camera 240 photographs the image of the foaming liquid in the second syringe 170 and sends the image to the control system to confirm whether the blood content in the foaming liquid meets the standard and the number and size of the microbubble embolus, to provide a reference for whether the subsequent foaming test result is accurate.

[0140] First foaming liquid injection step: after obtaining the foaming liquid, the foaming test device 100 switches to the fourth pipeline mode, and the second syringe 170 injects the foaming liquid into the human body. When the foaming liquid is injected into the human body, the second push force sensor 260 senses the size of the injection push force of the second syringe 170 (more specifically, the size of the push force of the output end 191 of the second syringe driving member), if the injection push force continues to rise, the system alarms and stops injection, and after adjusting the position of the indwelling needle, the test continues. And the second ultrasonic wave sensor monitors whether there are large bubbles when the foaming liquid passes. If there are, the control system alarms, and the device 100 is checked before the test is performed again to ensure that the foaming liquid injected into the vein of the human body is safe and reliable.

[0141] First tube sealing step: after the first foaming liquid injection step, the foaming test device 100 first switches to the second pipeline mode, and the second syringe 170 extracts physiological saline from the second container 110; then the foaming test device 100 switches to the first pipeline mode, and the first syringe 160 extracts physiological saline from the second container 110; the foaming test device 100 switches to the fourth pipeline mode, and the second syringe 170 injects physiological saline into the human body; finally, the foaming test device 100 switches to the fifth pipeline mode, and the first syringe 160 injects physiological saline into the human body, thus completing the control group foaming test.

[0142] In this step, when the first syringe 160 and the second syringe 170 extract physiological saline, the first ultrasonic wave bubble sensor 210 monitors whether there are bubbles when the physiological saline flows through, and alarms if there are, and then the pipeline 120 is checked and repaired; at the same time, when the first syringe 160 and the second syringe 170 inject physiological saline into the human body, the first push force sensor 250 senses the push force of the output end 181 of the first syringe driving member, and the second push force sensor 260 senses the push force of the output end 191 of the second syringe driving member, if the push force sensed by one of the push force sensors exceeds a certain range and still continues to rise, the system alarms.

[0143] Second foaming liquid injection step: repeat the operation of the foregoing mixed liquid extraction step and foaming liquid preparation step, after the foaming liquid is obtained, the patient performs blowing or Eustachian tube inflation test action, when the blowing or Eustachian tube inflation test action meets the standard, the foaming test device 100 is switched to the fourth pipeline mode, and the second syringe 170 injects the foaming liquid into the human body.

[0144] Second tube sealing step: repeat the operation of the first tube sealing step, and thus the foaming test of the test group is completed.

[0145] Before the first tube sealing step and the second tube sealing step, the pipeline 120 between the second syringe 170 and the indwelling needle remains the foaming liquid that is not injected into the human body, and the foaming liquid remaining in the pipeline can be pushed into the human body as much as possible through the tube sealing step, so that the sufficient injection of the foaming liquid is ensured as much as possible, and the pipeline is cleaned.

[0146] The device 100 of the present application does not need to manually extract physiological saline, air and blood, and does not need to manually inject foaming, only needs medical staff to install the injection consumables on the device 100, and the subsequent test device 100 can automatically complete the extraction, foaming, injection and emptying operations, saves the labor cost, and truly realizes that one person can complete the foaming test. Figure 12 The device 100 can also cooperate with the blowing device 300, and the real-time air pressure value is detected by the pressure sensor in the blowing device 300, so as to replace the Valsalva action, which is simple to operate and high in precision.
