Description

Technical Field

[0001] This invention relates to the field of cardiovascular equipment technology, specifically to an ultrasonic flow detection device for cardiovascular applications. Background Technology

[0002] An ultrasonic flow meter is an instrument that measures flow rate by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). Based on the principle of signal detection, ultrasonic flow meters can be classified into propagation velocity difference method (direct time difference method, time difference method, phase difference method and frequency difference method), beam offset method, Doppler method, cross-correlation method, spatial filtering method and noise method, etc.

[0003] Ultrasonic flow detection devices can also be called ultrasonic flow meters or ultrasonic flow meters. Before operation, an appropriate amount of ultrasonic conductive agent (gel) should be applied to the area to be tested. The ultrasonic conductive agent (gel) can reduce air barriers between the skin and the probe and help conduct ultrasonic signals. During operation, the ultrasonic probe needs to be gently placed in contact with the patient's skin. However, prolonged use of ultrasound may cause the ultrasound to produce a thermal effect on the skin tissue, resulting in changes in the local skin tissue temperature. Changes in skin tissue temperature can lead to inaccurate measurement results.

[0004] Therefore, we propose an ultrasonic flow detection device for cardiovascular applications to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasonic flow detection device for cardiovascular applications, in order to solve the problem mentioned in the background art that prolonged use of ultrasound may cause a thermal effect on skin tissue, resulting in changes in local skin tissue temperature, which in turn leads to inaccurate measurement results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic flow detection device for cardiovascular systems, comprising an ultrasonic blood flow detection mechanism, wherein a probe mechanism is installed at one end of the ultrasonic blood flow detection mechanism;

[0007] The probe mechanism includes a handheld lever and a probe body disposed at the lower end of the handheld lever. A vertical groove is formed on the outer periphery of the handheld lever, and an annular groove is also formed on the outer periphery of the lower end of the handheld lever. The vertical groove and the annular groove are connected.

[0008] The probe mechanism is provided with a gripping mechanism on its outer side. The gripping mechanism includes an outer sleeve and an arc-shaped cover fixedly installed at the lower end of the outer sleeve. A slider is fixedly installed on the inner wall of the outer sleeve. A rotating block is rotatably installed on the outer periphery of the slider. The rotating block is slidably installed in the vertical groove and the annular groove. A temperature sensor is embedded in the lower end of the outer sleeve.

[0009] The gripping mechanism is equipped with a temperature control mechanism, which includes a heating coil fixedly installed on the inner wall of the arc-shaped cover.

[0010] Preferably, the ultrasonic blood flow detection mechanism includes a terminal body, which is provided with a display screen, a control panel and a sound channel hole.

[0011] Preferably, the probe mechanism further includes a connecting wire, the two ends of which are connected to the handheld rod and the terminal body, respectively. The handheld rod has a threaded groove on its outer periphery, and a limiting plate is fixedly installed on the outer periphery of the handheld rod. The limiting plate is located at the upper end of the threaded groove.

[0012] Preferably, the gripping mechanism further includes a first discharge port opened at the lower end of the arc-shaped cover, a first elastic element fixedly installed at the upper end of the outer sleeve, a threaded sleeve fixedly installed at the upper end of the first elastic element, and the threaded sleeve being threadedly connected to the threaded groove body.

[0013] Preferably, the outer periphery of the gripping mechanism is provided with a first storage mechanism. The first storage mechanism includes a first storage cylinder mounted on the arc-shaped cover. The first storage cylinder has an annular structure. The upper end of the first storage cylinder is connected to a feed pipe, and the lower end of the first storage cylinder is provided with a discharge pipe, which is connected to the first discharge port.

[0014] Preferably, the heating coil is installed in the inner cavity of the outer sleeve, and the heating coil is also disposed at the lower end of the first storage cylinder. A heat-conducting plate is disposed on the outer periphery of the heating coil. The heat-conducting plate has an arc-shaped structure and fits into the inner cavity of the outer sleeve. Multiple heat-conducting plates are disposed, and adjacent heat-conducting plates are respectively disposed on both sides of the discharge pipe.

[0015] Preferably, one end of the heat-conducting plate is provided with a first arc-shaped portion, which is suspended on the heating coil, and the other end of the heat-conducting plate away from the first arc-shaped portion is provided with a second arc-shaped portion, the lower end of which is attached to the bottom wall of the arc-shaped cover.

[0016] Preferably, the gripping mechanism is provided with a second storage mechanism, which includes a second storage cylinder disposed inside the second arc-shaped portion. The second storage cylinder has a second discharge port at both its upper and lower ends. The second discharge port at the upper end of the second storage cylinder is connected to the discharge pipe, and the second discharge port at the upper end of the second storage cylinder is connected to the first discharge port.

[0017] Preferably, the lower end of the second material storage mechanism is provided with a limiting mechanism. The limiting mechanism includes a baffle disposed inside the second material storage cylinder. A connecting rod is fixedly installed at the lower end of the baffle. A ball bearing is rotatably installed at the lower end of the connecting rod. The ball bearing is rotatably installed inside the first discharge port. The lowest point of the ball bearing is lower than the lowest point of the arc-shaped cover.

[0018] Preferably, a second elastic element is installed between the baffle and the top wall of the second storage cylinder, and a sealing plate is fixedly installed at the lower end of the baffle, with the sealing plate covering the second discharge port.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The temperature of the heating coil in the ultrasound blood flow detection device can be adjusted. The heating coil can heat the patient's skin, reducing the discomfort caused by the cold ultrasound transducer. At the same time, during the detection process, the local temperature rise can also be displayed by the temperature sensor. At this time, the heating coil can be turned off, the probe body can be slid to other positions on the skin, and the detection can be repeated after the local area cools down. Multiple detections increase the accuracy of the detection results and improve patient comfort. This solves the problem mentioned in the background technology that prolonged use of ultrasound may cause the ultrasound to generate a thermal effect on the skin tissue, resulting in changes in local skin tissue temperature, which in turn leads to inaccurate measurement results.

[0021] 2. The ultrasonic conductive agent to be used is introduced into the first storage cylinder through the feed tube. The ultrasonic conductive agent flows out from the discharge tube and the first discharge port and flows directly onto the human skin. As the probe body and the arc-shaped cover slide left and right, the ultrasonic conductive agent is coated on the skin. There is no need for medical staff to apply it in advance, which is convenient to use.

[0022] 3. The heating coil, in conjunction with the heat-conducting plate, allows temperature to be quickly transferred to the ultrasonic conductive agent, ensuring that the ultrasonic conductive agent is not too cold after discharge. The temperature sensor constantly monitors the temperature, and shuts off the heating coil if it overheats. Similarly, when the local skin temperature is higher than the upper part of the heat-conducting plate, the heat-conducting plate, the first arc-shaped part, and the second arc-shaped part can also promptly dissipate the heat from the skin, further increasing the constant temperature at the detection site and improving the accuracy of the detection results.

[0023] 4. The second storage cylinder can also be used for material storage. The ultrasonic conductive agent in the first storage cylinder flows out sequentially from the discharge pipe, the second discharge port, and the first discharge port. The second storage cylinder is set at the lower end of the heat-conducting plate to further perform constant temperature treatment on the ultrasonic conductive agent.

[0024] 5. When the ball rolls on the skin, it moves upward under force, which drives the connecting rod, baffle and sealing plate to move upward, thereby opening the second discharge port and allowing the ultrasonic conductive agent to be discharged. When the arc-shaped cover slides on the skin, it is slid by the ball, which increases the flexibility of the arc-shaped cover. After the ultrasonic conductive agent is discharged, the rolling of the ball further increases the uniformity of the coating.

[0025] 6. After the arc-shaped cover is raised, under the action of the second elastic element, the ball bearings, connecting rod, baffle and sealing plate are reset, resealing the second discharge port, which is convenient for repeated use. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-4 and Figure 7 The present invention provides a technical solution: an ultrasonic flow detection device for cardiovascular system, comprising an ultrasonic blood flow detection mechanism 1, wherein a probe mechanism 2 is installed at one end of the ultrasonic blood flow detection mechanism 1.

[0037] The probe mechanism 2 includes a handheld lever 21 and a probe body 22 located at the lower end of the handheld lever 21. The probe body 22 is aligned with the blood vessels of the human body, and the relevant data can be displayed on the ultrasound blood flow detection mechanism 1.

[0038] A gripping mechanism 3 is provided on the outside of the probe mechanism 2. The gripping mechanism 3 includes an outer sleeve 31 and an arc-shaped cover 32 fixedly installed at the lower end of the outer sleeve 31. When medical staff operate the probe body 22, they hold the outer sleeve 31. The arc-shaped cover 32 at the lower end has a hollow structure inside. When it comes into contact with human skin, the area is large, which can smooth out the ultrasonic transducer and make it evenly applied to the human skin without the need for medical staff to smooth it manually. The arc-shaped cover 32 is located at the lower end of the medical staff's hand, which ensures that the ultrasonic transducer will not slip onto the medical staff's hand and also ensures that the medical staff's hand will not come into contact with human skin, thus reducing the spread of bacteria.

[0039] A vertical groove 24 is provided on the outer periphery of the handheld lever 21, and an annular groove 25 is also provided on the outer periphery of the lower end of the handheld lever 21. The vertical groove 24 and the annular groove 25 are connected.

[0040] A slider 36 is fixedly installed on the inner wall of the outer sleeve 31, and a rotating block 37 is rotatably installed on the outer periphery of the slider 36. The rotating block 37 is slidably installed in the vertical groove 24 and the annular groove 25.

[0041] The outer sleeve 31 and the arc-shaped cover 32 are an integral structure. They slide on the outer periphery of the handheld rod 21 via the slider 36 and the rotating block 37, and will not fall off. The height of the outer sleeve 31 can be adjusted according to the actual use. Medical staff can fix the position of the outer sleeve 31 and the handheld rod 21 by squeezing the outer sleeve 31. When the rotating block 37 of the outer sleeve 31 rotates in the annular groove 25, the arc-shaped cover 32 is slightly higher than the probe body 22. The arc-shaped cover 32 slides on the skin, and the probe body 22 presses against the skin, adapting to the fit of elastic skin and ensuring the authenticity of the test data.

[0042] A temperature sensor 38 is embedded in the lower end of the outer sleeve 31. The temperature sensor 38 is a DS18B20 and is electrically connected to the ultrasonic blood flow detection mechanism 1. It can detect the temperature of the probe body 22 and the skin contact point in real time, and the data results are displayed on the ultrasonic blood flow detection mechanism 1.

[0043] The gripping mechanism 3 is internally equipped with a temperature control mechanism 5, which includes a heating coil 51 fixedly installed on the inner wall of the arc-shaped cover 32. The heating coil 51 is electrically connected to the ultrasonic blood flow detection mechanism 1. The temperature of the heating coil 51 can be adjusted on the ultrasonic blood flow detection mechanism 1. The heating coil 51 can heat the patient's skin, reducing the discomfort caused by the cold ultrasonic transducer. At the same time, during the detection process, the local temperature rise can also be displayed by the temperature sensor 38. At this time, the heating coil 51 is turned off, and the probe body 22 is slid to other positions on the human skin. After the local area cools down, the detection is repeated. Repeated detection increases the accuracy of the detection results and improves the patient's comfort. This solves the problem mentioned in the background art that prolonged use of ultrasound may cause the ultrasound to produce a thermal effect on the skin tissue, resulting in changes in the local skin tissue temperature, which in turn leads to inaccurate measurement results.

[0044] Example 2: Please refer to Figures 1-4 The ultrasound blood flow detection mechanism 1 includes a terminal body 11, which is equipped with a display screen 12, a control panel 13 and a sound channel hole 14.

[0045] The probe mechanism 2 also includes a connecting line 23, the two ends of which are connected to the handheld rod 21 and the terminal body 11 respectively. The outer periphery of the handheld rod 21 is provided with a threaded groove 26, and a limiting plate 27 is fixedly installed on the outer periphery of the handheld rod 21. The limiting plate 27 is located at the upper end of the threaded groove 26.

[0046] The gripping mechanism 3 also includes a first discharge port 33 located at the lower end of the arc-shaped cover 32. A first elastic element 34 is fixedly installed at the upper end of the outer sleeve 31. A threaded sleeve 35 is fixedly installed at the upper end of the first elastic element 34. The threaded sleeve 35 is threadedly connected to the threaded groove 26.

[0047] The engagement between the threaded sleeve 35, the threaded groove 26, and the limiting plate 27 facilitates the adjustment of the height of the outer sleeve 31 and the threaded sleeve 35. This allows for adjustment of the initial height between the threaded sleeve 35 and the outer sleeve 31. When the threaded sleeve 35 rotates to abut the limiting plate 27, the resistance to downward sliding of the outer sleeve 31 and the arc-shaped cover 32 increases, preventing the rotating block 37 from sliding in the annular groove 25. This ensures that the sliding of the probe body 22 is visible and suitable for the usage habits of different medical personnel, making it widely applicable.

[0048] Example 3: Please refer to Figures 4-7 The outer periphery of the gripping mechanism 3 is provided with a first storage mechanism 4. The first storage mechanism 4 includes a first storage cylinder 41 installed on the arc-shaped cover 32. The first storage cylinder 41 has an annular structure. The upper end of the first storage cylinder 41 is connected to the feed pipe 42, and the lower end of the first storage cylinder 41 is provided with a discharge pipe 43. The discharge pipe 43 is connected to the first discharge port 33.

[0049] The ultrasonic conductive agent to be used is introduced into the first storage cylinder 41 through the feed pipe 42. The ultrasonic conductive agent flows out from the discharge pipe 43 and the first discharge port 33 and flows directly onto the human skin. As the probe body 22 and the arc-shaped cover 32 slide left and right, the ultrasonic conductive agent is coated on the skin. There is no need for medical staff to apply it in advance, which is convenient to use.

[0050] The heating coil 51 is installed in the inner cavity of the outer sleeve 31. The heating coil 51 is also located at the lower end of the first storage cylinder 41. A heat-conducting plate 52 is provided on the outer periphery of the heating coil 51. The heat-conducting plate 52 has an arc-shaped structure and fits into the inner cavity of the outer sleeve 31. Multiple heat-conducting plates 52 are provided. Adjacent heat-conducting plates 52 are respectively located on both sides of the discharge pipe 43. The contact area between the heat-conducting plate 52 and the first storage cylinder 41 is relatively large.

[0051] After the heating coil 51 is turned on, its temperature is adjustable. With the help of the heat-conducting plate 52, the temperature can be quickly transferred to the ultrasonic conductive agent, so that the ultrasonic conductive agent after discharge will not be too cold. The temperature sensor 38 monitors the temperature at all times, and turns off the heating coil 51 once it overheats.

[0052] One end of the heat-conducting plate 52 is provided with a first arc-shaped part 53, which is suspended on the heating coil 51. The end of the heat-conducting plate 52 away from the first arc-shaped part 53 is provided with a second arc-shaped part 54, and the lower end of the second arc-shaped part 54 is attached to the bottom wall of the arc-shaped cover 32.

[0053] By setting the first arc-shaped part 53 and the second arc-shaped part 54, not only is the contact area with the first storage cylinder 41 increased, but the downward-bent part can directly fit the skin, so that the part of the arc-shaped cover 32 felt by the skin is also at a suitable temperature, and the heat conduction effect is good.

[0054] Similarly, when the local skin temperature is higher than the upper part of the heat-conducting plate 52, the heat-conducting plate 52, the first arc-shaped part 53 and the second arc-shaped part 54 can also conduct heat from the skin in a timely manner, further increasing the constant temperature at the detection site and increasing the accuracy of the detection results.

[0055] Example 4: Please refer to Figures 4-6 The gripping mechanism 3 is equipped with a second storage mechanism 6. The second storage mechanism 6 includes a second storage cylinder 61, which is located inside the second arc-shaped part 54. The upper and lower ends of the second storage cylinder 61 are provided with second discharge ports 62. The second discharge port 62 located at the upper end of the second storage cylinder 61 is connected to the discharge pipe 43, and the second discharge port 62 located at the lower end of the second storage cylinder 61 is connected to the first discharge port 33.

[0056] The ultrasonic conductive agent in the first storage cylinder 41 flows out sequentially from the discharge pipe 43, the second discharge port 62, and the first discharge port 33. The second storage cylinder 61 is located at the lower end of the heat-conducting plate 52 to further perform constant temperature treatment on the ultrasonic conductive agent.

[0057] Example 5: Please refer to Figure 4 , Figure 6 and Figure 8 The lower end of the second storage mechanism 6 is provided with a limiting mechanism 7. The limiting mechanism 7 includes a baffle 71 disposed inside the second storage cylinder 61. A connecting rod 72 is fixedly installed at the lower end of the baffle 71. A ball bearing 73 is rotatably installed at the lower end of the connecting rod 72. The ball bearing 73 is rotatably installed inside the first discharge port 33. The lowest point of the ball bearing 73 is lower than the lowest point of the arc-shaped cover 32.

[0058] A second elastic element 74 is installed between the baffle 71 and the top wall of the second storage cylinder 61, and a sealing plate 75 is fixedly installed at the lower end of the baffle 71.

[0059] In the initial state, the sealing plate 75 covers the second discharge port 62, sealing the second discharge port 62. The ultrasonic conductive agent inside the first storage cylinder 41 and the second storage cylinder 61 will not flow out from the first discharge port 33, and the ultrasonic conductive agent can be stored in the first storage cylinder 41 and the second storage cylinder 61 for a long time.

[0060] When the ball bearing 73 rolls on human skin, it moves upward under force, causing the connecting rod 72, baffle 71, and sealing plate 75 to move upward, thereby opening the second discharge port 62 and allowing the ultrasonic conductive agent to be discharged. When the arc-shaped cover 32 slides on the skin, it is slid by the ball bearing 73, which increases the flexibility of the arc-shaped cover 32. After the ultrasonic conductive agent is discharged, the rolling of the ball bearing 73 further increases the uniformity of the coating.

[0061] After the arc-shaped cover 32 is lifted, under the action of the second elastic element 74, the ball 73, connecting rod 72, baffle 71 and sealing plate 75 are reset, resealing the second discharge port 62, which is convenient for repeated use.

[0062] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
