Finger-worn ultrasound imaging providing and vascular guide device and method

[0001] The present disclosure relates to an ultrasound image providing and blood vessel guiding device and a method thereof. More specifically, the present disclosure relates to a finger-worn ultrasound image providing and blood vessel guiding device and a method thereof.

[0002] While portable ultrasound devices and near-infrared mapping technology are currently used for locating blood vessels, they may have limitations in practically guiding needle insertion due to their bulk or the fact that they are limited to confirming only the approximate location of the vessels.

[0003] In particular, vein visualization devices using near-infrared methods project only the surface location of blood vessels, making it difficult to track the actual process of the needle entering the tissue in real time and prone to aiming errors. Additionally, some portable ultrasound devices require holding the probe with one hand and manipulating the needle with the other, which complicates the procedure and disperses the user's gaze, potentially reducing accuracy.

[0004] Although automated blood collection devices using robots have been attempted, the cumbersome installation and maintenance of the devices make immediate use difficult in emergency situations or wards, and their poor accessibility to the human body may impose limitations in clinical settings.

[0005] To address these problems, there is an increasing need for technology that allows for simultaneous vascular tactile sensation using the operator's fingers and ultrasound image guidance.

[0006] The purpose of the embodiments disclosed in this disclosure is to provide a device and method that enable an operator to perform a blood vessel puncture accurately and safely while palpating the blood vessel in real time and checking the ultrasound image through a finger-worn ultrasound guide device.

[0007] In addition, the embodiments disclosed in this disclosure aim to provide a device and method that can increase the accuracy of vascular puncture by utilizing a stereo vision sensor and a needle guide laser to track the 3D position and insertion angle of the needle, thereby adding visual guidance to the operator.

[0008] In addition, the embodiments disclosed in this disclosure aim to provide a device and method that are conveniently worn on a finger to accurately and rapidly support the vascular puncture process for patients for whom vein identification is difficult, such as the elderly, children, anticancer patients, and obese patients.

[0009] In addition, the embodiments disclosed in this disclosure aim to provide a device and method that can reduce injection failures and increase work efficiency in clinical settings by synthesizing three-dimensional position tracking of a medical procedure instrument with ultrasound images to guide in real time whether it enters a blood vessel and the insertion angle.

[0010] The problems that this disclosure aims to solve are not limited to those mentioned above, and other unmentioned problems will be clearly understood by a person skilled in the art from the description below.

[0011] An apparatus according to the present disclosure for achieving the aforementioned technical objectives may include: a finger holder on which a user’s finger is worn; an ultrasound probe installed on the finger holder and acquiring an ultrasound image of a blood vessel; a display module installed on the finger holder and displaying the ultrasound image; a memory storing at least one process related to the operation of acquiring and displaying the ultrasound image; and a processor that performs an operation according to the process.

[0012] In addition, the finger fixation device may have any one of a shape that surrounds the finger, a ring shape, and a band type shape.

[0013] Additionally, the display module may extend from the finger holder in a direction different from the longitudinal direction of the finger.

[0014] In addition, the ultrasound probe may be installed on the outer surface of the finger holder to enable measurement of the blood vessel.

[0015] Additionally, it may further include a sensor module for acquiring the three-dimensional position and insertion angle of a medical procedure instrument inserted into the target skin toward the blood vessel.

[0016] In addition, the processor can generate a guide message that guides the insertion of the medical procedure instrument based on the three-dimensional position and the insertion angle, and display the guide message through the display module.

[0017] In addition, it may further include an output module that outputs the above guide message as voice.

[0018] In addition, the processor can generate a three-dimensional image of the medical procedure device based on the three-dimensional position and the insertion angle, and synthesize the ultrasound image and the three-dimensional image to display an image of the medical procedure device entering the blood vessel through the display module.

[0019] In addition, it may further include a laser module that outputs a laser to guide the insertion position of the medical procedure device.

[0020] Additionally, a method performed by a device according to the present disclosure for achieving the technical problem described above, comprising: a finger holder on which a user’s finger is worn; an ultrasonic probe installed on the finger holder; a display module installed on the finger holder; a memory in which at least one process related to the operation of acquiring and displaying an ultrasonic image is stored; and a processor that performs an operation according to said process, may include the steps of: the processor acquiring an ultrasonic image of a blood vessel through the ultrasonic probe; the processor displaying the ultrasonic image through the display module; the processor acquiring a three-dimensional position and an insertion angle of a medical procedure instrument inserted into target skin toward the blood vessel through a sensor module; the processor generating a guide message that guides the insertion of the medical procedure instrument based on the three-dimensional position and the insertion angle; and the processor displaying the guide message through the display module.

[0021] In addition to this, a computer-readable recording medium for recording a computer program for implementing the present disclosure may be further provided.

[0022] According to the present disclosure, even for patients whose blood vessels are not easily visible, such as the elderly, children, and anticancer patients, blood vessel puncture can be performed while viewing real-time images through a finger-worn ultrasound probe and a display, thereby providing the effect of increasing the success rate of injection and significantly reducing patient discomfort caused by insertion failure.

[0023] According to the present disclosure, by integrating an ultrasound probe into the operator's finger, there is no need to hold the equipment with the other hand, which simplifies the movement path during the procedure and allows for the simultaneous use of tactile sensation and images with one hand, thereby providing the effect of shortening the procedure time and improving work efficiency.

[0024] According to the present disclosure, by selectively combining a stereo vision sensor and a needle guide laser, the position and angle of needle insertion can be visually guided, thereby accurately identifying the moment the needle enters the blood vessel and providing the effect of reducing bleeding or the number of retry attempts.

[0025] According to the present disclosure, since it is implemented as a small finger-worn structure, it can be immediately utilized in various environments such as hospital wards, emergency rooms, ambulances, and field sites, thereby providing excellent portability and mobility, and enabling even medical personnel with low proficiency in procedures to use it stably.

[0047] FIG. 1 is a block diagram briefly structured to represent an apparatus according to an example of the present invention, FIG. 2 is an example diagram briefly structured to represent an apparatus according to an example of the present invention, and FIG. 3 is a usage state diagram briefly structured to represent an apparatus according to an example of the present invention.

[0048] Referring to FIGS. 1 to 3, a finger-wearable vascular guide device (10) according to the present disclosure may be configured to allow a user to safely and accurately insert a medical procedure instrument (e.g., a needle (2) or a catheter) during vascular puncture by wearing it on one finger, and may include a finger holder (100), an ultrasound probe (200), a display module (300), a processor (400), a memory (500), a sensor module (600), an output module (700), a laser module (800), and a power module (900).

[0049] In one embodiment, the finger restraint (100) may be worn on the finger of a user (e.g., a medical professional). For example, the finger restraint (100) may have a shape that surrounds the user's finger (6), a ring shape, and a band-type shape.

[0050] For example, the finger holder (100) can be implemented in various shapes so that the user's (e.g., medical staff) finger can be inserted and safely maintained during the procedure. For example, the finger holder (100) can be designed as a cylindrical structure that completely surrounds the user's finger (6), a ring shape, or a band type with adjustable length. Depending on these structural differences, the holder (100) can simultaneously ensure convenience and stability to suit each procedure environment.

[0051] In one embodiment, a cushioning pad or an elastic body may be placed inside the finger holder (100) to minimize discomfort even when a medical professional performs a procedure for a long time. The cushioning pad adheres to the ergonomic curved surface and naturally deforms with the movement of the finger (6), and can assist in preventing the device from shaking even if the medical professional changes their posture or applies pressure to the finger during the procedure. The elastic body can inflate or contract the holder (100) like an air cushion to adjust it to the thickness of the finger, thereby increasing convenience when attaching or detaching the device and reducing the possibility of the device coming off during the procedure.

[0052] In one embodiment, the outer surface of the finger holder (100) can be designed so that no unnecessary friction or slippage occurs when a medical professional gently moves the finger (6) over the skin to locate blood vessels. For example, by using a silicone-based material or a synthetic resin coating, problems of adhesion and friction caused by sebum, sweat, etc., can be resolved, and an ultrasound probe (200) or sensor module (600) located near the operator's finger can be stably supported. In particular, in a band-type form, Velcro or a clip may be attached so that the user can simply adjust the length after wrapping it around the finger (6), and a double locking structure may be adopted to prevent the fixation from coming undone.

[0053] In one embodiment, a sensor for detecting the wearing status is additionally embedded inside the finger fixation device (100) as needed, so that the processor (400) can automatically determine whether the operator has fully worn the device on the finger (6). Through this, if the wearing status is incomplete or shaking is detected, a warning message or voice guidance can be provided through the display module (300) or output module (700), and the medical staff can readjust the finger or re-check the fixation status to improve the accuracy of the procedure.

[0054] In one embodiment, an ultrasound probe (200) is installed on the finger holder (100) and can acquire an ultrasound image (3) of the blood vessel (1). For example, the ultrasound probe (200) may be installed on the outer surface of the finger holder (100) so as to be able to measure the blood vessel (1).

[0055] For example, an ultrasound probe (200) is mounted on the outer surface of a finger holder (100) so that the operator can accurately scan the blood vessel (1) area with ultrasound the moment the operator places the finger on the patient's skin. At this time, the processor (400) can digitally process the reflected signal acquired by the probe (200) in real time to immediately provide an internal image (3) containing the blood vessel structure to the display module (300). Through this configuration, the operator can effectively identify the location, depth, thickness, etc. of the blood vessel (1) and finely adjust the needle insertion angle or depth during the procedure.

[0056] In one embodiment, the shape of the probe (200) may be miniaturized and designed to be smoothly joined to the outer surface of the finger holder (100). For example, the probe (200) may be implemented in the form of a ring or a thin panel and manufactured to adhere closely to the curved surface of the finger holder (100), thereby minimizing shaking of the device when moving over the skin or during the needle insertion process. Additionally, the probe (200) and the finger holder (100) may be configured with a detachable structure, allowing only the probe to be quickly replaced or sterilized, and various probe specifications (frequency band, beam pattern, etc.) may be adopted to suit the procedure environment.

[0057] In one embodiment, the ultrasound probe (200) is positioned near the fingertip, allowing the operator to directly trace the path of the blood vessel (1) and simultaneously obtain an internal image (3) simply by moving the finger (6). This provides the ability to perform both sensory localization and image-based localization with a single finger, thereby eliminating the inconvenience of having to hold a separate ultrasound device to manipulate the needle. In particular, as the internal tissue changes as the needle approaches the blood vessel, the procedure can be verified step-by-step through the ultrasound image (3), which increases the accuracy of the procedure and reduces the number of re-insertions required during the procedure, thereby alleviating patient pain.

[0058] In one embodiment, a gel may be applied to the surface of the probe (200) or a gel pad may be attached to increase the contact force between the skin and the ultrasound element. This allows the operator to obtain a clear ultrasound image (3) while moving their finger smoothly over the patient's skin, and reduces reflection loss, thereby allowing the structure of the blood vessel (1) to be visualized more clearly. If necessary, the probe (200) may be synchronized with a sensor module (600) or a laser module (800) to provide comprehensive guidance to the operator by combining two-dimensional cross-sectional information of the ultrasound image with three-dimensional tracking information or optical guidelines.

[0059] In one embodiment, a display module (300) is installed on the finger holder (100) and can display the ultrasound image (3). For example, the ultrasound image (3) may include a blood vessel (1) and an injection needle (2).

[0060] For example, the display module (300) is coupled to the finger holder (100) to provide the operator with an ultrasound image (3) transmitted in real time from the ultrasound probe (200). The display module (300) is implemented with a relatively small size and appropriate resolution, which helps to immediately check the condition of the blood vessel (1) or injection needle (2) while moving the finger (6) slightly. In particular, by extending in a direction different from the length of the finger (6), the operator can view the image (3) without significantly changing their gaze while keeping the finger on the skin, thus simplifying the movement path in confined spaces or emergency situations.

[0061] In one embodiment, the display module (300) can provide an image of the inside of the blood vessel (1) and the path of the needle (2) within the device itself, without the need to carry a separate external device. To this end, the processor (400) can convert the reflected signal acquired by the ultrasound probe (200) into image data, apply a necessary image processing algorithm (e.g., filtering, edge detection, 2D→3D synthesis), and transmit it to the display module (300). Through this screen, the operator can clearly identify the relative positions of the blood vessel and the injection needle, and more intuitively adjust the insertion angle or depth.

[0062] In one embodiment, the display module (300) can display (output) various information processed by the device. For example, in addition to the ultrasound image (3), guide messages or warning messages can be displayed through a UI (User Interface) or GUI (Graphic User Interface) to provide auxiliary information regarding the progress of needle insertion, depth, puncture angle, etc. Medical personnel can use the interface of the display (300) to immediately change setting values ​​(e.g., laser brightness, 3D tracking mode, etc.) or quickly recognize problems occurring during the procedure. To this end, the screen may be configured to receive user input by equipping it with a simple touch sensor or a physical button.

[0063] In one embodiment, the viewing angle or operability may vary depending on where the display module (300) is positioned on the finger holder (100). For example, if placed at the center of the upper surface of the finger (6), the screen is most visible, but the thickness must be minimized; if placed on the side, the viewing angle becomes somewhat narrower, but there is less interference with other parts, which can increase design flexibility. This placement method can be applied in various ways depending on the patient type, the type of procedure, the proficiency of the medical staff, etc. If necessary, if the display module (300) is designed to have a hinge or a rotation axis to adjust the angle, user convenience can be further enhanced.

[0064] Meanwhile, the display module (300) is not only capable of displaying simple images, but can also be linked with an application or operating environment (e.g., an OS-based interface) running on the device to simultaneously display procedure records or patient information during the vascular puncture process. For example, when the procedure record button is pressed, it may be possible to implement a function to capture the current ultrasound image (3) screen or to input a patient ID and transmit it to a linked hospital server. At this time, if a communication module such as Wi-Fi or Bluetooth is additionally installed to enable remote data transmission and reception, rapid collaborative treatment can be performed in emergency situations.

[0065] In one embodiment, the sensor module (600) can obtain the three-dimensional position and insertion angle of a medical procedure instrument (injection needle (2)) inserted into the target skin toward the blood vessel (1).

[0066] For example, the sensor module (600) can provide additional spatial information that is difficult to ascertain from ultrasound images (3) alone by precisely tracking the three-dimensional position and insertion angle of a medical instrument (injection needle (2)) inserted into the target skin toward a blood vessel (1).

[0067] In one embodiment, the sensor module (600) can measure the movement of the needle tip in real time by using a stereo vision sensor to calculate the coordinates of the needle (2) along the X, Y, and Z axes, or by applying other optical marker recognition techniques. These measurement results can be transmitted to a processor (400) and processed into three-dimensional information combined with an ultrasound image (3), and the operator can intuitively check which path the needle (2) approaches the blood vessel (1) through a three-dimensional guide or graphic display line overlaid on the display module (300). In particular, even if medical personnel perform tactile-based blood vessel exploration using their fingers (6), the insertion angle or depth of the needle (2) can be adjusted more precisely when the three-dimensional data derived from the stereo vision sensor is presented together. This can be effective in reducing the number of injection failures and preventing patient pain or increased procedure time caused by needle re-insertion.

[0068] In one embodiment, the sensor module (600) may additionally detect shaking or vibration levels of the needle (2) to help the processor (400) determine stability during the procedure. For example, if the sensor module (600) analyzes the measured angular velocity or acceleration and determines that the needle vibration is excessive, the processor (400) may display a warning or provide voice guidance through the display module (300) or output module (700). This warning function may also be utilized as a precautionary measure to prevent damage to the blood vessel (1) or tissue bleeding.

[0069] For example, the sensor module (600) may include at least one of LiDAR (Light Detection and Ranging), proximity sensor, illumination sensor, touch sensor, acceleration sensor, magnetic sensor, gravity sensor (G-sensor), gyroscope sensor, motion sensor, RGB sensor, infrared sensor (IR sensor: infrared sensor), fingerprint sensor (finger scan sensor), ultrasonic sensor, optical sensor (e.g., camera), microphone, environmental sensor (e.g., including at least one of a barometer, hygrometer, thermometer, radiation detection sensor, heat detection sensor, gas detection sensor), and chemical sensor (e.g., healthcare sensor, biometric sensor, etc.). Meanwhile, the device may combine and utilize information sensed from at least two of these sensors.

[0070] In one embodiment, the laser module (800) can output a laser (4) that guides the insertion position of the medical procedure instrument (injection needle (2)).

[0071] For example, the laser module (800) is an optical indicator device for guiding the insertion position of a medical procedure instrument (injection needle (2)), and can project a laser (4) onto the patient's skin so that the operator can accurately insert the needle (2) into the target blood vessel area. The laser module (800) is linked with a processor (400) within the device and can be controlled to accurately indicate the actual insertion point based on the position information of the blood vessel (1) and three-dimensional coordinates measured by the ultrasound probe (200) or the sensor module (600). The operator can use this laser (4) as a visual reference line to grasp the angle and position for puncturing the needle (2) at a glance, thereby minimizing the aiming error that occurs during blood vessel puncture.

[0072] In one embodiment, the laser module (800) can be implemented in various ways depending on the usage environment. For example, a spot laser can be displayed on the skin surface, or the entire insertion path can be drawn with a line laser, and the beam intensity or focal length can be adjusted in various ways so that it can be clearly seen even under bright lighting. The processor (400) can assist the operator by receiving the insertion depth or angle of the needle (2) from the sensor module (600) at any time, dynamically adjusting the projection position of the laser (4), or displaying the corresponding correction information on the display module (300). Through this, real-time guidance can be provided by making the laser guide line move slightly on the patient's skin or changing the color or blinking pattern.

[0073] In one embodiment, by utilizing a laser (4), the problem of medical personnel having to aim at blood vessels (1) using only visual estimation or near-infrared mapping can be significantly resolved. In particular, even when blood vessels under the patient's skin are complexly branched or are difficult to see due to the elderly or chemotherapy, the needle (2) can be correctly punctured by relying on the laser guide line, thus contributing to reducing the number of re-insertions due to failure and the procedure time. Additionally, since the laser module (800) has a small body and can be placed on the side of the finger holder (100) or near the display module (300), an optical guidance function can be secured without significantly increasing the overall volume of the device.

[0074] In one embodiment, to set the projection angle or distance of the laser (4), the laser module (800) can rotate the beam using a micro gear or a rotation axis inside the module, or automatically correct the beam focus through an electronic control method. If the operator wants to use it by adjusting the position moment by moment from the skin surface until the insertion of the needle (2) is completed, the processor (400) can be linked with the sensor module (600) to update the projection point of the laser beam in real time. In this way, the laser module (800) can combine the laser guide line visible to the operator's eye, the ultrasound image (3), and the three-dimensional needle coordinate data from the sensor module (600) to enable more comprehensive and accurate guidance for vascular puncture.

[0075] In one embodiment, the output module (700) can perform the role of transmitting a guide message generated by the processor (400) in the form of voice or a warning sound.

[0076] For example, the output module (700) can perform the role of delivering a guide message generated by the processor (400) in the form of voice or warning sound. This output module (700) can not only provide simple sound output but also transmit information such as the needle insertion angle or blood vessel location in various voice notifications, so that the operator can receive auditory guidance in addition to visual information. In particular, in emergency scenes or narrow operating spaces where visual monitoring is not sufficiently performed while holding a syringe (7) in one hand and wearing a device on the other finger (6), voice warnings or guidance messages can provide intuitive guidelines.

[0077] In one embodiment, the output module (700) may be configured to include a receiver, a speaker, a buzzer, etc., so that the operator can immediately hear key information necessary for vascular puncture. For example, by playing voice messages such as "Insert the needle deeper" or "Deviated from the central axis of the blood vessel," the operator can accurately adjust the needle insertion even in situations where it is difficult to focus their gaze. Additionally, by adjusting the voice volume or the type of warning sound to suit the environment, the operator can maintain concentration without being disturbed by ambient noise or the sound of the device's operation.

[0078] In one embodiment, the output module (700) may be linked with the processor (400) to dynamically generate voice messages based on data detected by the sensor module (600) or the laser module (800). For example, as the needle (2) approaches the blood vessel (1), it may provide specific notifications such as "distance remaining to the blood vessel is 2mm," or if the error exceeds a certain standard, it may immediately sound a warning sound to minimize the risk of blood vessel damage. Since the auditory guidance works complementarily with the visual information, the operator wearing the device (10) can receive stable voice feedback along with real-time video verification with just one finger, thereby significantly reducing the failure of blood vessel puncture.

[0079] In one embodiment, the output module (700) may additionally have the function of playing multimedia messages. For example, the processor (400) may summarize and announce AI algorithm results or patient status information stored inside the device in voice, thereby enabling medical staff to quickly make a decision regarding the procedure. In addition, in emergency situations, words such as "emergency" or "danger" may be repeatedly played in a strong tone, or a specific alert sound pattern may be sounded to induce the operator to respond immediately.

[0080] In one embodiment, the power module (900) can supply power to the finger-worn vascular guide device (10). For example, the power module (900) may include a battery or an external power interface to supply stable power to the finger-worn vascular guide device (10). It may be implemented in various forms, such as using a rechargeable lithium-ion battery to enhance portability or connecting via a wired connection to a power source within a hospital, and can be operated selectively depending on the procedure situation.

[0081] In one embodiment, the memory (500) may store at least one process related to the operation of acquiring and displaying the ultrasound image (3). For example, the memory (500) may provide a storage area for storing a program (process) for acquiring, displaying, and processing sensor data of the ultrasound image (3).

[0082] For example, the memory (500) can store data supporting various functions of the device and programs for the operation of the processor, and can store input / output data (e.g., music files, still images, videos, etc.), and can store a number of application programs (or applications) running on the device, data for the operation of the device, and instructions. At least some of these application programs can be downloaded from an external server via wireless communication.

[0083] Such memory (500) may include at least one type of storage medium among flash memory type, hard disk type, SSD type (Solid State Disk type), SSD type (Silicon Disk Drive type), multimedia card micro type, card type memory (e.g., SD or XD memory, etc.), RAM (random access memory; RAM), SRAM (static random access memory), ROM (read-only memory; ROM), EEPROM (electrically erasable programmable read-only memory), PROM (programmable read-only memory), magnetic memory, magnetic disk, and optical disk. Additionally, the memory (500) may be a database that is separated from the device but connected via wired or wireless connection.

[0084] In one embodiment, the processor (400) can perform an operation according to at least one process related to the operation of acquiring and displaying the ultrasound image (3).

[0085] For example, the processor (400) can perform the role of a core control unit that controls the overall operation of the device (10), and can control the process of processing the ultrasound image (3) and transmitting the image to the display module (300), and can also integrally manage the three-dimensional information provided by the sensor module (600) or the operating status of the laser module (800). The processor (400) can analyze data regarding the insertion position and angle of the medical procedure instrument (injection needle (2)), and if necessary, can visually output a guide message through the display module (300) or provide voice guidance through the output module (700).

[0086] For example, the processor (400) may be implemented with a memory that stores data for an algorithm or a program that reproduces the algorithm for controlling the operation of components within the device, and at least one processor (not shown) that performs the aforementioned operation using the data stored in the memory. In this case, the memory and the processor may each be implemented as separate chips. Alternatively, the memory and the processor may be implemented as a single chip.

[0087] At least one component may be added or removed in response to the performance of the components illustrated in FIG. 1. Additionally, it will be readily understood by those skilled in the art that the relative positions of the components may be changed in response to the performance or structure of the system.

[0088] Meanwhile, all or at least some of the components shown in Fig. 1 refer to software and / or hardware components such as Field Programmable Gate Arrays (FPGAs) and Application Specific Integrated Circuits (ASICs).

[0089] The device (10) of the present invention configured as described above can be worn on the user's finger (6) as shown in FIG. 3 and can guide the process of inserting a needle (2) into a blood vessel (1) while in contact with the arm (5) of the subject being measured. The user can detect the location where the blood vessel (1) is present by gently sliding the finger (6) over the skin of the arm (5), and can view the ultrasound image (30) obtained from the ultrasound probe (200) in real time through the display module (300). At this time, since the relative positions of the blood vessel (1) and the needle (2) are continuously displayed on the image (30), the user can easily identify the exact puncture site.

[0090] In the example shown in FIG. 3, it can be seen that the syringe (7) has already penetrated the skin of the arm (5) together with the device (10). The user can visually check the cross-section of the blood vessel (1) through the device (10) and determine whether the needle (2) is properly positioned inside the blood vessel. In this process, a sensor module (600) or a laser module (800) may be additionally used. The sensor module (600) can track the three-dimensional position or insertion angle of the needle (2) and provide guide information determined by the processor in the form of an overlay on the display module (300), and the laser module (800) can help the operator to more intuitively align the puncture position by optically marking the insertion site.

[0091] According to the present embodiment, the user can comfortably wear the device (10) on the finger (6) and move the finger to a target area on the arm (5) to view the ultrasound image (30) acquired by the ultrasound probe (200). When the blood vessel (1) appears clearly on the screen, the needle (2) can be inserted gradually deeper to accurately enter the blood vessel, and any errors or trial-and-error that may occur at this time can be effectively reduced through the real-time image (30) and guide information displayed on the display module (300). In particular, as shown in FIG. 3, since the device (10) mounted on the finger (6) is small and light even when the syringe (7) is connected, the arm (5) can be stably supported while the blood vessel puncture can be easily performed with only one hand.

[0092] With this example of use, the user can quickly visualize the blood vessel (1) even in elderly patients or cancer patients for whom it was previously difficult to locate blood vessels, and accurately puncture by inserting the needle (2) at an appropriate angle. Furthermore, through the structure shown in FIG. 3, the device (10) is easy to carry, and the syringe (7) can be operated stably while checking the real-time ultrasound image (30) even in places where the procedure environment is limited (e.g., ambulance, field medical facility, etc.), so the success rate of the procedure can be improved and the burden on the patient can be reduced.

[0093] FIG. 4 is a flowchart illustrating a blood vessel guide method according to an example of the present invention. The operations of FIG. 4 can be performed by the device (10) described in FIG. 1.

[0094] Referring to FIG. 4, in one embodiment, the processor (400) can detect the user's wearing in operation 21. For example, the processor (400) can detect whether the user's finger is worn on the finger holder (100). At this time, the processor (400) can determine whether the user's finger (6) is properly attached through a contact sensor or pressure sensor provided on the finger holder (100), and can check whether an environment has been secured for the device (10) to operate normally during a future procedure. If the wearing state is unstable or the wearing is not recognized, the processor (400) can display an appropriate re-wearing guidance message on the display module (300) or provide a voice warning through the output module (700).

[0095] In one embodiment, in operation 22, the processor (400) can acquire an ultrasound image (3) of a blood vessel (1) through the ultrasound probe (200). For example, the processor (400) can acquire an ultrasound image (3) of a blood vessel (1) by driving the ultrasound probe (200). At this time, the ultrasound probe (200) is fixed to the end or side of the finger holder (100), and when the user moves the finger (6) over the skin of the subject to be measured, ultrasound can be irradiated to the corresponding area and the reflected signal can be received. The processor (400) can convert this reflected signal into a digital signal and analyze the blood vessel (1) or surrounding tissue structure by applying an internally mounted image processing algorithm (e.g., filtering, boundary detection, automatic gain control, etc.).

[0096] For example, the processor (400) may also automatically save specific frames in which the blood vessel (1) is observed, or predict and recommend the blood vessel path through an AI algorithm. At this time, if the wall thickness and flow characteristics of the blood vessel (1) are measured together, more advanced guidance may be provided, such as suggesting a safe point when inserting a needle (not shown) or predicting the probability of puncture failure. For example, if the lumen of the blood vessel is narrowed in an elderly patient or a patient undergoing anticancer treatment, the processor (400) may be programmed to display a message on the screen such as "Blood vessel diameter narrowed, caution required."

[0097] In one embodiment, in operation 23, the processor (400) can display the ultrasound image (3) through the display module (300). For example, the processor (400) can display the ultrasound image (3) in real time on the display module (300). At this time, the display module (300) immediately updates the image (3) transmitted from the ultrasound probe (200) in accordance with the movement of the finger (6), thereby allowing the operator to continuously check the internal topography of the blood vessel or potential insertion path. The operator can observe how the cross-section of the ultrasound image (3) changes each time the finger (6) is moved slightly over the target skin, and can determine an appropriate puncture point by estimating the tissue surrounding the blood vessel (1) or the needle insertion location in advance.

[0098] In one embodiment, the display module (300) is extended in a direction different from the length of the finger, so that the user can intuitively check the condition of the blood vessel (1) without having to turn their head or significantly divert their gaze. To this end, the display module (300) can be placed on the finger holder (100) to have an appropriate angle or height, and if necessary, it can be designed with a structure that allows the screen to be rotated or folded to flexibly respond to the procedure environment. Through this screen, the operator can visually estimate the needle insertion depth or angle and reduce the error with the central axis of the blood vessel from the initial stage.

[0099] In one embodiment, in operation 24, the processor (400) can output a laser (4) that guides the insertion position of the medical procedure instrument (injection needle (2)) through the laser module (800).

[0100] For example, the processor (400) can drive the laser module (800) in operation 24 to project a laser (4) onto the skin surface to optically mark the area where the needle (2) is to be punctured. At this time, the laser module (800) may be configured to mark the puncture location in the form of a spot or a line, and the processor (400) may correct the projection point of the laser (4) in real time by referring to the location of the blood vessel (1) or three-dimensional coordinate information obtained from the ultrasound probe (200) or the sensor module (600). By inserting the needle (2) along the laser (4) mark, the operator can accurately approach the target blood vessel (1) and significantly reduce the risk of failure in blood vessel puncture.

[0101] In one embodiment, the laser module (800) is miniaturized so that it can operate effectively even in an environment where the size of the device is limited, and can be mounted around the finger holder (100) or the display module (300). The processor (400) adjusts the brightness, beam angle, focal length, etc. of the laser (4) according to user settings or automatic calculation results, and depending on the situation, can display the entire insertion path of the needle (2) as a line or display the target point only as a point. This allows the puncture angle error to be reduced by ensuring that the location of the blood vessel (1) confirmed in the ultrasound image (3) and the laser (4) indicator point coincide with each other when the operator slowly inserts the needle (2).

[0102] In one embodiment, the laser module (800) can appropriately control the light source output so that the optical guide line projected onto the skin surface is clearly visible according to the treatment environment. For example, the laser intensity can be automatically increased under bright lighting, and visibility can be improved by using a complementary color laser when the patient's skin is dark. In addition, the laser (4) is equipped with a function that makes the dot blink or change color as it approaches the target point, allowing the operator to perceive the moment of puncture more intuitively.

[0103] In one embodiment, in operation 25, the processor (400) can obtain the three-dimensional position and insertion angle of a medical procedure instrument (injection needle (2)) inserted into the target skin toward the blood vessel (1) through the sensor module (600).

[0104] For example, the processor (400) obtains the three-dimensional position and insertion angle of the needle (2) through the sensor module (600) in operation 25, thereby allowing the operator to determine the specific path the needle travels toward the blood vessel (1) without relying on a simple two-dimensional ultrasound cross-section. The sensor module (600) can calculate the position of the tip of the needle (2) in X, Y, and Z coordinates by applying a stereo vision sensor, other optical marker tracking device, or near-field wireless positioning technology, and simultaneously estimate angle information such as tilt or rotation angle. The processor (400) receives this data periodically and can calculate the depth at which the needle (2) penetrates the skin, the relative distance from the blood vessel (1), the puncture angle, etc., in real time.

[0105] To this end, the sensor module (600) can estimate three-dimensional coordinates by analyzing a display pattern or reflection marker located near the needle (2) or by collecting an optical signal reflected from the surface of the needle. For example, if a stereo vision structure equipped with two or more cameras is used, the speed at which the tip of the needle moves at a certain point can be extracted with relatively high precision. The processor (400) can combine this spatial coordinate information with an ultrasound image (3) to construct an advanced guidance screen that simultaneously displays the path of the needle (2) and a cross-section of the blood vessel (1) on the display module (300).

[0106] In particular, when the blood vessels are located deep, such as in elderly or obese patients, it may be difficult to determine whether the needle (2) is approaching the blood vessel (1) perpendicularly or at what angle it is entering using only simple 2D ultrasound images. However, the 3D position and angle information provided by the sensor module (600) can reduce needle insertion errors and prevent the situation where the needle touches the blood vessel wall crookedly and damages the blood vessel. Based on this data, the processor (400) can display a numerical notification such as "needle insertion angle tilted 10° to the right" or generate a warning sound to induce the operator to immediately correct the angle.

[0107] Additionally, the sensor module (600) can automatically detect when the puncture is completed while tracking the movement of the needle (2). For example, when the needle approaches a specific reference point (e.g., near the central axis) of the blood vessel (1), the processor (400) can be controlled to display a guidance message such as "blood vessel access complete" or to send a voice guidance to the output module (700). This allows the operator to safely complete the puncture without having to rely entirely on visual or tactile senses.

[0108] In one embodiment, in operation 26, the processor (400) may generate a guide message guiding the insertion of the medical procedure instrument (injection needle (2)) based on the three-dimensional position and the insertion angle. For example, the processor (400) may generate a guide message guiding the insertion of the needle (2) by utilizing the three-dimensional position and the insertion angle. For example, the processor (400) may generate specific phrases such as "lower the needle angle a little more" or "insert a little deeper," or express information to assist the operator's operation through graphic guide lines.

[0109] In addition, alternatively, the processor (400) can generate a three-dimensional image of the medical procedure instrument (injection needle (2)) based on the three-dimensional position and the insertion angle, and can generate a guide image of the medical procedure instrument (injection needle (2)) entering the blood vessel (1) by synthesizing the ultrasound image (3) and the three-dimensional image. For example, the processor (400) can support the operator in performing the puncture operation more intuitively by synthesizing the three-dimensional position and the ultrasound image (3) to visualize the process of the needle (2) entering the blood vessel (1) as a three-dimensional guide image.

[0110] In one embodiment, in operation 27, the processor (400) can display the guide message or guide image through the display module (300).

[0111] For example, the processor (400) visually displays a guide message or a guide image on the display module (300) in operation 27 to help the operator perform the blood vessel puncture procedure more accurately. This goes beyond simple text guidance or static screens, and by adding a graphic overlay to the ultrasound image (3) or visualizing a 3D rendered model of the blood vessel (1) and needle (2), the operator can intuitively understand the internal condition of the blood vessel and the needle insertion path. For example, the processor (400) can receive the 3D coordinates of the needle transmitted from the sensor module (600) or projection information from the laser module (800) and overlay the movement of the blood vessel (1) and the needle on the display (300) screen.

[0112] In one embodiment, a text message such as “needle angle X°, Ymm remaining to center of blood vessel” may be displayed on the screen of the display module (300), or the progress of needle insertion may be displayed as a bar graph. If necessary, the trajectory of the needle may be displayed in a line form along with a cross-section of the blood vessel (1), allowing the operator to intuitively know how far to adjust the position on the skin. Additionally, by using a three-dimensional rendered model, the blood vessel puncture path can be predicted more precisely even in cases where the blood vessel (1) is complexly located, such as in elderly patients or obese patients.

[0113] In one embodiment, the processor (400) can transmit the same message as voice through the output module (700). For example, in situations where it is difficult to look away while viewing the ultrasound image (3), or in noisy and chaotic environments such as an emergency scene, voice guidance can provide immediate and clear warnings or instructions to the operator. At this time, the output module (700) can play guidance voice such as "needle insertion angle 5 degrees excessive" or "2mm remaining to blood vessel" to allow the operator to quickly correct the insertion action even if their gaze is directed elsewhere.

[0114] In particular, the guide video and voice message are linked so that when the needle insertion approaches a dangerous level, the screen changes color and simultaneously sounds a warning sound, or conversely, when it is within a safe range, a reassuring message is displayed, allowing the practitioner to proceed with the procedure with peace of mind. The processor (400) can utilize this complex notification function to reduce the workload of medical staff and reduce re-insertion or blood vessel damage caused by trial and error.

[0115] In one embodiment, in operation 28, the processor (400) may output a message indicating the completion of the blood vessel guide operation through the display module (300) or the output module (700). For example, the processor (400) may output a message indicating the completion of the blood vessel guide operation through the display module (300) or the output module (700). This may occur when the processor (400) recognizes that the needle (2) has stably reached the target blood vessel (1) or confirms through user input that the procedure has been successfully completed. Through this completion message, the operator realizes that the procedure has been properly finished and can proceed with subsequent procedures, such as blood collection or drug injection, using the syringe (7).

[0116] FIG. 5 is an exemplary diagram illustrating a simplified structure of an apparatus according to another example of the present invention. Descriptions of configurations identical to those disclosed in FIG. 1 to 3 are omitted.

[0117] Referring to FIG. 5, a device (10') according to another example of the present invention may include a finger holder (100) made in the form of a belt, a miniaturized display module (300), and a power cable (8).

[0118] Specifically, the device (10') adopts a belt-type structure that can be adjusted in length to fit the finger (6), so that the operator can easily fix it regardless of the thickness of the finger and securely adhere it so that the device does not shake or detach during the procedure.

[0119] The finger fixation device (100) can be made of a flexible material so that discomfort can be minimized even when the medical staff wear the device for a long time. In particular, thanks to its design in the form of a belt, the operator can quickly attach and detach the device, and the task of attaching or replacing a disposable cover for sterilization can also be easily performed. Unlike the fixation device presented in other examples of the present invention, the belt structure of such a finger fixation device (100) provides stable support without wrapping the entire finger, so it may have the advantage of being able to move freely over the patient's body and explore blood vessels.

[0120] The miniaturized display module (300) can be positioned to allow sufficient reading of ultrasound images or guide information while reducing the overall volume of the device (10'). The display module (300) allows medical personnel to monitor the vascular puncture process in real time without significantly shifting their field of view during the procedure, thereby greatly improving portability and immediacy compared to the conventional method of using bulky ultrasound devices. Since the operator does not need to hold a separate device with the other hand, they can accurately view the ultrasound image with one hand and perform the vascular puncture by holding a needle or catheter in the other hand.

[0121] The power cable (8) can be configured to be equipped with a small battery or connected via a wire to an internal hospital power supply. In particular, this device (10') can be combined with a portable battery pack so that the operator can use it quickly in emergency situations or military field medical environments, or it can have the flexibility to maintain operation for a long time via a wired connection in a hospital environment where power is supplied stably. When the power supply is stable, output limitations are reduced when driving additional modules such as ultrasound probes or stereo vision sensors, making it possible to achieve higher resolution images or display colorful guide interfaces.

[0122] The device (10') configured in this way can be stably mounted even when the ultrasound probe (200) or sensor module (600) placed inside the finger holder (100) is miniaturized, and can sufficiently perform the core function for blood vessel puncture. As shown in FIG. 5, the operator can place the device on a finger (6) convenient for the procedure, such as the thumb or index finger, and connect the power cable (8) to the hospital system, and then refer to the image displayed on the display module (300) to accurately check the location of the blood vessel or the angle of needle insertion. This method drastically simplifies the procedure environment that previously relied on external monitors or large ultrasound devices, and can be easily applied even when performing procedures on various parts of the body.

[0123] FIG. 6 is an exemplary diagram showing a simplified structure of a device according to another example of the present invention. FIG. 7 is a diagram showing a simplified structure of a device according to another example of the present invention. Descriptions of configurations identical to those disclosed in FIG. 1 to 3 are omitted.

[0124] Referring to FIGS. 6 and FIGS. 7, a device (10) according to another example of the present invention may include a cylindrical finger holder (100) into which a finger is inserted and a healthcare display module (300).

[0125] Specifically, a device (10) according to another example of the present invention can be implemented by integrating a cylindrical finger holder (100) into which a finger (6) is inserted and a display module (300) that combines healthcare functions. In this case, the cylindrical finger holder (100) is a structure having a constant inner diameter, unlike a belt or band, and can be designed to be naturally fixed simply by inserting the user's finger (6). This cylindrical structure minimizes external protrusions when worn, forming a smooth shape with the practitioner's finger, and allows the practitioner's movement to be more free.

[0126] According to the usage state shown in FIG. 7, the device (10) can intuitively assist in the process of inserting a needle (2) into a blood vessel (1) simultaneously with the procedure operation using a finger (6). For example, a display module (300) is installed on the upper part of the finger holder (100) so that it can display the internal condition of the blood vessel or the position information of the needle (2) along with healthcare information while the user performs blood vessel puncture. According to a specific embodiment, the display module (300) adopts the form of a conventional smartwatch-based healthcare display to additionally provide medical-related data such as pulse and blood oxygen concentration, thereby supporting the monitoring of the operator's vital signs.

[0127] The ultrasound probe (200) mounted on the device (10) can be separately embedded internally, or an ultrasound element can be placed on the side or end of the finger holder (100) to scan the blood vessel (1) in real time at the moment the user contacts the target skin with their finger (6). Through this, medical personnel can make more detailed judgments by considering not only the ultrasound image displayed on the healthcare display module (300) but also data associated with pulse or blood pressure. If necessary, it may also be possible to increase the accuracy of blood vessel puncture by combining a stereo vision sensor or a laser module.

[0128] The inner wall of the cylindrical finger holder (100) can be finished with a flexible material such as silicone to comfortably wrap around the finger (6), and an anti-slip treatment or cushioning pad may be added to prevent the device from coming off during the procedure. The user can attach the device to the finger (6) as shown in FIG. 7 and operate the syringe (7) while checking the relative positions of the blood vessel (1) and the needle (2) through the screen of the display module (300). The operator can perform a blood vessel puncture with one hand without any other support device, and if necessary, can also check the patient's condition immediately through a healthcare measurement function.

[0129] Such a device (10) can be quickly applied in both hospitals and emergency situations, and can improve portability and convenience compared to methods using existing ultrasound equipment or separate large sensors. Since the operator only needs to insert their finger into the cylindrical fixation device (100), the setup time for using the device is reduced, and clinical work efficiency can be maximized. In addition, the healthcare display module (300) can output additional information linked to the patient's condition in addition to the vascular image, so real-time monitoring and procedure judgment can be performed at a glance.

[0130] Meanwhile, although not shown in the drawing, the processor (400) can reset and optimize parameters including the type of ultrasound, frequency, depth, and resolution of the ultrasound probe.

[0131] For example, the processor (400) can image various parts of the body, not merely scanning vascular structures, by resetting and optimizing various parameters including the type of ultrasound probe, frequency, depth, and resolution. For instance, the processor (400) can flexibly adjust the operation of the ultrasound probe, such as increasing the frequency to clearly view superficial tissues or changing the resolution mode to explore deep areas, depending on the purpose of the examination or patient characteristics. This optimization is also linked with the sensor module (600) or the display module (300), allowing the operator to easily obtain ultrasound images of various anatomical structures simply by moving their finger.

[0132] Additionally, the processor (400) images and accesses anatomical structures within the body to enable biopsy, drainage, or injection using a needle or inventional device for diagnostic or therapeutic clinical procedures, and said anatomical structures may include cysts, fluid collections, lesions, and tumors.

[0133] For example, the processor (400) can support biopsy, drainage, injection, etc., using a needle or interventional device to perform diagnostic or therapeutic clinical procedures. This can help to accurately target anatomical structures such as cysts, fluid collections, lesions, and tumors located outside of blood vessels, based on a real-time image map provided by an ultrasound probe. The user can perform medical actions such as safely inserting a needle, collecting a sample, or draining fluid by changing the device settings or referring to a guide image overlaid on the display, according to optimal parameter values ​​(e.g., frequency band, scan angle, depth setting) calculated by the processor (400).

[0134] FIG. 8 is a flowchart illustrating a medical procedure method using a device according to an example of the present invention. The operations of FIG. 8 can be performed by the device (10) described in FIG. 1.

[0135] To understand the overall operation of the present invention, a medical procedure method using the device (10) is described as follows.

[0136] Referring to FIG. 8, in one embodiment, in operation 31, the user can inspect the device (10) and turn on the power. For example, the user can check the battery charge status or whether the power cable is connected, and check whether the processor boots correctly, thereby preventing unexpected power shortage or device malfunction during the procedure. If necessary, the user can check the initial screen of the device (10) through the display module (300) and check in advance whether the sensor module or laser module is operating.

[0137] In one embodiment, in operation 32, the user can wear the device (10) on their finger. For example, whether the finger holder (100) is in the form of a band, belt, or cylinder, the operator can adjust it so that the device (10) is securely fixed without shaking by fitting it comfortably onto their finger (6). During this process, the length or inner diameter of the finger holder (100) is adjusted to fit the thickness of the finger, and if there is a wear sensor, the processor can recognize that the attachment is complete and complete the initial setup.

[0138] In one embodiment, in operation 33, the user can prepare the subject of measurement. For example, the user can prepare the patient, who is the subject of measurement, in a state suitable for the procedure. This may include guiding the patient to assume a comfortable position, disinfecting the site to be explored for blood vessels, or using a tourniquet if necessary. At this time, by checking patient information, medical history, and scheduled procedure details in advance, the blood vessel puncture can be performed safely.

[0139] In one embodiment, in operation 34, the user can use the device (10) to locate the blood vessel. For example, the user can move the finger (6) over the subject's skin and view the ultrasound image transmitted through the ultrasound probe (200) in real time on the display module (300). By doing so, the location, thickness, and surrounding tissue condition of the blood vessel (1) can be quickly identified, thereby allowing the puncture point to be determined.

[0140] In one embodiment, in operation 35, the user can set up a laser and 3D tracking using the device (10). For example, the user can set up a laser module and a 3D tracking function (sensor module) within the device (10). When the laser module (800) is activated, a light spot or beam can be projected onto the surface of the skin to visually indicate the needle insertion location, and when the sensor module (600) is turned on, the needle (injection needle) is tracked in 3D coordinates so that the processor (400) can calculate the treatment angle or depth more precisely. At this stage, the user can adjust the desired tracking mode or laser brightness, and check the guide lines displayed on the display module (300) to create an optimal treatment environment.

[0141] In one embodiment, in operation 36, the user can insert a needle and monitor an ultrasound image using the device (10). For example, the user can actually insert the needle and monitor the ultrasound image through the device (10). During this process, as the needle (injection needle) slowly enters the blood vessel, the cross-section of the needle may appear as a bright line in the ultrasound image, and when combined with three-dimensional tracking data, the display module (300) can visually and numerically confirm how close the needle is to the central axis of the blood vessel (1) and whether the insertion angle is appropriate. The operator can refer to this information to immediately fine-tune the direction of needle insertion, and the laser pointer can also display the needle's path on the skin to reduce injection failure.

[0142] In one embodiment, in operation 37, the user can perform blood collection or drug administration from a blood vessel. For example, the user can perform necessary medical actions, such as blood collection or drug administration from a blood vessel. Once it is confirmed by ultrasound imaging or 3D tracking data that the needle has properly settled within the blood vessel, the operator can collect blood or inject drugs or nutrient solution through a prepared syringe (or catheter). At this time, the processor (400) may detect the movement of the needle in real time and provide an alarm regarding whether the needle has moved out of the blood vessel. The operator can minimize bleeding by simply supporting or pressing the blood vessel area with a finger wearing the device (10).

[0143] In one embodiment, in operation 38, the user can complete the blood collection or drug administration operation. For example, the user can complete the blood collection or drug administration operation. The needle can be slowly withdrawn, and post-treatment such as hemostasis or disinfection can be performed. The fixation device can be removed from the finger (6) wearing the device (10) to disinfect or to maintain it for reuse. If necessary, a procedure completion message or summary information can be displayed on the display module (300), and a voice notification of the end of the operation can be provided through the output module (700). This allows the user to efficiently complete the blood vessel puncture process and charge or clean the device (10) in preparation for the next procedure.

[0144] Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium that stores instructions executable by a computer. The instructions may be stored in the form of program code and, when executed by a processor, may generate a program module to perform the operation of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

[0145] Computer-readable recording media include all types of recording media that store instructions that can be decoded by a computer. Examples include ROM (Read Only Memory), RAM (Random Access Memory), magnetic tape, magnetic disk, flash memory, optical data storage devices, etc.

[0146] As described above, the disclosed embodiments have been explained with reference to the attached drawings. Those skilled in the art will understand that the present disclosure may be practiced in forms different from the disclosed embodiments without changing the technical spirit or essential features of the present disclosure. The disclosed embodiments are illustrative and should not be interpreted restrictively.
