Description

[Technical Field]

[0001] TECHNICAL FIELD This disclosure relates to computer-aided identification, and in particular to the use of computer-aided identification in medical procedures. [Background technology]

[0002] In the past, failure to properly identify a patient could result in, among other things, transfusion errors, medication errors, wrong-person treatment, testing errors, and / or wrong medical procedure site errors. Patient misidentification can be a root cause of medical procedure errors. Areas where patient misidentification can occur include, among other things, surgical interventions, blood transfusions, drug administration, and / or phlebotomy. Patient misidentification can occur due to name structure (e.g., similar names), inaccurate birth dates, clothing that conceals identity, an unconscious patient, errors when registering a patient through a computerized system, missing identification wristbands, identification wristbands that identify a different (e.g., wrong) patient, etc. Furthermore, failure to properly identify a patient's eye can also result in, among other things, transfusion errors, medication errors, wrong-person treatment, testing errors, and / or wrong medical procedure site errors. Summary of the Invention [Means for solving the problem]

[0003] The present disclosure provides a system capable of receiving a first patient's identification. In one example, the system may receive the first patient's identification from a medical professional. In another example, the system may receive the first patient's identification by scanning the patient's wristband. The system may further obtain first eye identification information including a first plurality of iris structures associated with a first eye of the first patient based on at least the first patient's identification. The system may further identify a second plurality of iris structures for the current patient's eye. The system may further determine whether the second plurality of iris structures matches the first plurality of iris structures. If the second plurality of iris structures matches the first plurality of iris structures, the system may further provide an indication that the first eye has been correctly identified. If the second plurality of iris structures does not match the first plurality of iris structures, the system may further provide an indication that the first eye has not been correctly identified.

[0004] The first eye identification information may further include at least one distance measurement associated with the first eye. For example, the at least one distance measurement associated with the first eye may include at least one of a distance measurement from the cornea of ​​the first eye to a lens of the first eye, a distance measurement from the lens of the first eye to the retina of the first eye, a corneal thickness of the first eye, and a lens thickness of the first eye. The system may further identify at least one distance measurement of the current patient's eye. For example, the at least one distance measurement associated with the current patient's eye may include at least one of a distance measurement from the cornea of ​​the current patient's eye to a lens of the current patient's eye, a distance measurement from the lens of the current patient's eye to the retina of the current patient's eye, a corneal thickness of the current patient's eye, and a lens thickness of the current patient's eye. The system may further identify whether the at least one distance measurement of the current patient's eye matches the at least one distance measurement associated with the first eye. If the second plurality of iris structures matches the first plurality of iris structures and the at least one distance measurement of the current patient's eye matches the at least one distance measurement associated with the first eye, the system may be configured to provide an indication that the first eye has been correctly identified. If the at least one distance measurement of the current patient's eye does not match the at least one distance measurement associated with the first eye, the system may be configured to provide an indication that the first eye has not been correctly identified.

[0005] The system may further obtain medical procedure information based on at least the first patient identification and one of a second plurality of iris structures of the current patient's eye. The system may further provide the medical procedure information via at least one of the display and the microscope-integrated display.

[0006] A first iris structure of the first plurality of iris structures can be separated from a second iris structure of the first plurality of iris structures by a first angle relative to the center of the pupil of the first eye. A first iris structure of the second plurality of iris structures can be separated from a second iris structure of the second plurality of iris structures by a second angle relative to the center of the pupil of the current patient's eye. For example, to determine whether the second plurality of iris structures matches the first plurality of iris structures, the system may further determine whether the second angle matches the first angle.

[0007] A first iris structure of the first plurality of iris structures may be a first distance from the center of the pupil of the first eye. A first iris structure of the second plurality of iris structures may be a second distance from the center of the pupil of the current patient's eye. For example, to determine whether the second plurality of iris structures matches the first plurality of iris structures, the system may further determine whether the second distance matches the first distance.

[0008] The current patient may be a first patient. The eye of the current patient may be a second eye of the first patient that is different from the first eye. In one example, the first eye may be the patient's right eye and the second eye may be the patient's left eye. In another example, the first eye may be the patient's left eye and the second eye may be the patient's right eye.

[0009] The present disclosure further includes a non-transitory computer-readable memory device having instructions having instructions, which when executed by a processor of the system, cause the system to perform the steps described above.

[0014] In the following description, details are set forth as examples to facilitate discussion of the disclosed subject matter. However, it should be apparent to those skilled in the art that the disclosed embodiments are examples and do not encompass all possible embodiments.

[0015] As used herein, a reference number refers to a class or type of entity, and any letter following such a reference number refers to a particular instance of a particular entity of that class or type. Thus, for example, a virtual entity referenced by "12A" may refer to a particular instance of a particular class / type, and the reference number "12" may refer generally to a set of instances belonging to that particular class / type or to any one instance of that class / type.

[0016] The medical systems may be utilized to identify a patient. In one example, a first medical system may be utilized a first time in identifying a patient prior to a medical procedure. In another example, a second medical system may be utilized a second time in identifying a patient prior to a medical procedure. The second time may be at a later time than the first time. In one example, the first medical system may be utilized in a doctor's office. In another example, the second medical system may be utilized in a surgical facility.

[0017] The first medical system may associate two or more identifying attributes associated with the patient. For example, the two or more identifying attributes associated with the patient may include two or more of the patient's name, the patient's address, the patient's telephone number, the patient's government-issued identification number or string, the patient's date of birth, the patient's first medical facility identification, and the patient's first eye identification, among others. The patient's first eye identification may be utilized via an eye recognition process, method, and / or system to identify the patient and / or the patient's eye.

[0018] The second medical system may associate two or more identification attributes with the patient. For example, the two or more identification attributes associated with the patient may include two or more of the patient's name, the patient's address, the patient's telephone number, the patient's government-issued identification number or string, the patient's date of birth, the patient's first medical facility identification, the patient's second first medical facility identification, the patient's first eye identification, and the patient's second eye identification, among others. The second medical system may utilize an eye recognition process, method, and / or system to obtain the patient's second eye identification and determine whether the patient's first eye identification and the patient's second eye identification match. If the patient's first eye identification and the patient's second eye identification match, the second medical system may proceed with a medical procedure associated with the patient. For example, the medical procedure associated with the patient may include a surgical procedure associated with the patient.

[0019] If the patient's first eye identification and the patient's second eye identification match, a medical procedure may be acquired based at least on the identification associated with the patient. The identification associated with the patient may include the patient's first eye identification and / or the patient's second eye identification. For example, the medical system may acquire medical procedure information from a database. The medical system may acquire medical procedure information from the database based at least on the identification associated with the patient. In one example, the database may identify multiple medical procedure information by patient identification. In another example, the database may identify multiple medical procedure information by iris structure of each eye. Each patient's eye identification may include information associated with the iris structure of each of the one or more eyes. Each patient's eye identification may include information associated with one or more measurements of each of the one or more eyes. The medical procedure may be acquired automatically. For example, the automatic acquisition of the medical procedure may include automatic loading of the medical procedure. The medical procedure may include a pre-planned treatment. For example, the pre-planned treatment may be automatically loaded for the matching patient and / or the patient's matching eyes. Automatically loading a medical procedure may allow a physician (e.g., a surgeon) to initiate and / or begin the medical procedure. The medical procedure may be displayed via the microscope-integrated display and / or the medical system display. In one example, this may shorten the time for the medical procedure compared to not automatically loading the medical procedure. In another example, this may reduce one or more errors that may occur when performing one or more medical procedures. If a medical procedure is automatically loaded for a physician based at least on an identification associated with a patient, a medical procedure may not be performed on the wrong patient.

[0020] If the patient's first eye identification and the patient's second eye identification do not match, the medical procedure associated with the patient may not proceed. In one example, an error or warning may be generated that may notify medical personnel that the patient has not been correctly identified. In another example, an error or warning may be generated that may notify medical personnel that the patient's eye has not been correctly identified.

[0021] One or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes may be utilized to identify a patient's eye. For example, eye recognition may be based on identifying a patient by analyzing a pattern based at least on one or more structures of the patient's eye and / or one or more shapes of one or more portions of the patient's eye. In one example, eye recognition may identify eye features by extracting landmarks and / or features from an image of the patient's eye. In a second example, eye recognition may identify eye features by identifying one or more structures of the iris of the patient's eye. In a third example, eye recognition may identify eye features by identifying one or more patterns of the retina of the patient's eye. In another example, eye recognition may identify eye features by determining one or more depth measurements of the patient's eye. The depth measurements of the patient's eye may include distance measurements from the cornea of ​​the patient's eye to the lens of the patient's eye. The depth measurements of the patient's eye may include distance measurements from the lens of the patient's eye to the retina of the patient's eye. The one or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes may identify data associated with the patient's eye. The data associated with the patient's eye may include a template. For example, the template may include data that can be utilized to distinguish the eye of a first patient from the eye of a second patient different from the first patient, such that the template can be distinguished from a photograph.

[0022] The one or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes may utilize three-dimensional technology, particularly utilizing one or more projectors and / or one or more sensors, to determine information regarding the shape of the patient's eye. For example, the information regarding the shape of the patient's eye may be utilized to determine one or more features of the surface of the patient's eye. The one or more features of the surface of the patient's eye may include, among other things, the contour of the eye. An advantage of utilizing three-dimensional eye recognition technology may be that the three-dimensional eye recognition technology may not be affected by changes in lighting. The one or more eye recognition systems, one or more eye recognition methods, and / or one or more eye recognition processes may utilize multiple image sensors. For example, the multiple image sensors may include multiple cameras. The three-dimensional eye recognition technology may utilize multiple image sensors.

[0023] The eye recognition system may include one or more image capture devices. For example, the one or more image capture devices may include one or more cameras. The eye recognition system may include one or more light projectors. In one example, the light projectors may project infrared light. In another example, the light projectors may include lasers. The eye recognition system may identify a location on the patient's eye. For example, the location on the patient's eye may be utilized in identifying a template of the patient's eye. The template of the patient's eye may be associated with a topography of the patient's eye. The template of the patient's eye may be utilized in eye recognition. In one example, the template of the patient's eye may be compared to another template in confirming or denying the identity of the patient. In another example, the template of the patient's eye may be compared to another template in confirming or denying the identity of the patient's eye.

[0024] A medical procedure associated with a patient may include a portion of the patient (e.g., a site of a medical procedure). For example, a portion of the patient may resemble another portion of the patient. For example, a patient's right eye may resemble a patient's left eye. For example, a patient's right eye may appear similar to a patient's left eye. A medical procedure associated with a patient may be for that portion of the patient and not for other portions of the patient. For example, a medical procedure associated with a patient may be for the patient's right eye and not for the patient's left eye. The second medical system may utilize a computer vision process, method, and / or system to identify the portion of the patient from other portions of the patient. The computer vision process, method, and / or system may utilize an eye recognition process, method, and / or system to identify the portion of the patient from other portions of the patient. For example, the second medical system may identify a surgical tool instrument as being in an area not associated with the portion of the patient. The second medical system may issue a warning or error if the second medical system identifies a surgical tool instrument as being in an area not associated with the portion of the patient. In one example, if the medical procedure is for a patient's right eye (e.g., the site of the medical procedure), the second medical system may issue a warning or error if the second medical system determines that the surgical tool instrument is in a region not associated with the patient's right eye. In another, if the medical procedure is for a patient's right eye (e.g., the site of the medical procedure), the second medical system may issue a warning or error if the second medical system determines that the surgical tool instrument is in a region associated with the patient's left eye.

[0025] Referring now to FIG. 1A , an example of a medical system is shown. As shown, a medical system 110 may be utilized with a patient 120. As shown, the medical system 110 may include a computer system 112. The computer system 112 may be communicatively coupled to displays 116A and 116B. As an example, the computer system 112 may be integrated with the display 116. The computer system 112 may be communicatively coupled to a biometric device 114. In one example, the biometric device 114 may include one or more cameras. In another example, the biometric device 114 may include a three-dimensional scanner. The biometric device 114 may be utilized in biometric measurements of an eye 122 of a patient 120. As shown, the display 116A may display an image 130A associated with the eye 122 of the patient 120. As shown, the display 116B may display an image 130B associated with the eye 122 of the patient 120.

[0026] The computer system 112 may determine eye-identification information. For example, the eye-identification information may include biometric information associated with the eye 122 of the patient 120. The biometric information associated with the eye 122 may include, among others, one or more of: a blood vessel pattern of the sclera of the eye 122; an iris structure of the eye 122; a location of the iris structure of the eye 122; a distance measurement from the cornea of ​​the eye 122 to the lens of the eye 122; a distance measurement from the lens of the eye 122 to the retina of the eye 122; a corneal topography of the eye 122; a retinal pattern of the eye 122; a corneal thickness of the eye 122; a lens thickness of the eye 122; and a wavefront measurement.

[0027] As shown, display 116B may display a pattern of blood vessels 132 in the sclera of eye 122. As shown, display 116B may display iris structures 134A-134C of eye 122. As shown, display 116B may display display areas 136A-136D. In one example, display area 136 may display a distance measurement from the cornea of ​​eye 122 to the lens of eye 122, a distance measurement from the lens of eye 122 to the retina of eye 122, the location of structures in iris 134, corneal topography information, or wavefront measurement information, among other biometric information associated with eye 122. In another example, display area 136 may display any information associated with patient 120.

[0028] A person 150 may operate the medical system 110. For example, the person 150 may be a medical professional. The person 150 may enter identifying information associated with the patient 120 into the computer system 112. The identifying information associated with the patient 120 may include, among other things, one or more of the patient's 120 name, the patient's 120 address, the patient's 120 telephone number, the patient's 120 government-issued identification number, the patient's 120 government-issued identification string, and the patient's 120 date of birth. In one example, the computer system 112 may associate the identifying information associated with the patient 120 with the eye recognition information. In another example, the computer system 112 may associate the identifying information associated with the patient 120 with a template.

[0029] Person 150 may verify one or more portions of the identification information associated with patient 120 before computer system 112 associates the identification information associated with patient 120 with the eye recognition information. For example, one or more portions of the identification information associated with patient 120 may be stored via a storage device accessible by computer system 112 before medical system 110 is utilized with patient 120. Person 150 may set data associated with a portion of patient 120. For example, person 150 may set data associated with the right eye of patient 120.

[0030] Person 150 may provide medical procedure information associated with patient 120 to computer system 112. The medical procedure information may be associated with a medical procedure. The medical procedure information may be associated with identification information associated with patient 120. Computer system 112 may store the medical procedure information. For example, computer system 112 may store the medical procedure information for later use. The medical procedure information may be associated with a surgery. For example, the medical procedure information may be obtained before a surgery. The medical procedure information may be used during the medical procedure. For example, the medical procedure may include a surgery.
