Background technology
Present various medical supersonic diagnostic device such as B ultrasonic etc. have been widely used in the clinical diagnosis of each hospital, can observe the anatomical structure of patient's interior tissue and organ except traditional black and white is super, color ultrasound can improve the clinical application range of ultrasonic diagnostic equipment to endovascular blood flow imaging greatly by using Doppler effect.
But in present clinical practice, the maximum performance of efficient of ultrasonic diagnostic equipment that had individual problems affect, that is exactly patient's an identity identification problem.
In traditional ultrasonic diagnostic equipment, when patient checked, the doctor needed at first to press " New Patient " key (key of perhaps similar newly-built patient's inspection record function) on the lower keyboard, then input patient's information in ejecting the dialog box of coming.Fig. 2 has provided the sketch map of the keyboard of a secondary traditional ultrasonic diagnostic equipment, marked " New Patient " this button 1 among the figure, the name of the button of different manufacturers is different, also has other extra button on the keyboard that has, but their function is similar, all is that patient information is managed.Fig. 3 has provided the sketch map of input patient information dialog box, comprise patient ID number, check ID number, patient name, sex, date of birth, check data etc., and the inspection item once accepted in the past of patient.The interface that different equipment vendors provide is different.The basic function of this dialog box is to allow the doctor import patient's information, the interface of the manufacturer that has also allows to import certain conditions and carries out searching of patient, combination condition such as the name by patient, sex, date of birth etc. is searched, improved the robustness and the reliability of patient status's identification like this, very high because the identical patient of these querying conditions in fact belongs to same patient's probability.But because information is manual input, it is very big that patient information is filled out wrong probability, relatively more crucial querying conditions such as picture patient's name, date of birth, as long as there is a place to input by mistake, will cause identical patient's inspection data to be classified as different patients so, become very difficult thereby make passing data have access to medical history inquiry by system.So also reduce the quantity of information that offers the doctor, may reduce the accuracy of diagnosis.In addition,, a patient checks, so because different operator's input habit makes that patient data's merging is particularly difficult if having done on different machines repeatedly.
For some high-grade ultrasonic diagnostic equipments, also support to attempt to alleviate this problem by network service.By the Worklist Query in the DICOM agreement (international standard of medical imaging network transmission), ultrasonic diagnostic equipment can with a Worklist server communication, and the Worklist server is by HL7 agreement (Healthcare Level 7, the international standard of common therapy information network transmission) can communicate by letter with hospital information system (HIS), from HIS, obtain patient's information.This method makes the operation doctor of ultrasonic diagnostic equipment not need to import patient information, thereby makes that be dispersed in each patient information typing above equipment originally concentrates on typing above the HIS of registry, thereby has significantly reduced the probability of typing mistake.At present a lot of large hospitals are integrated IC-card in oneself HIS system, and patient information directly follows IC-card to associate, and has so further reduced the probability of patient status's identification error.But still there are some problems at present, can take others' IC-card to go to register such as patient, left behind IC-card when perhaps going sick, done a new IC-card again, so all can cause the former inspection data of patient and work as inferior inspection data and can not combine, so this method still not the most reliable.
In addition, the mode of this entry information on the conventional ultrasound diagnostic device, for the doctor without any restriction, the doctor can press " New Patient " key at any time and add a new inspection record, record before perhaps revising so just makes insurance fraud realize than being easier on technological means; When going out malpractice, the doctor also can revise protocol at an easy rate in addition; The private data that a bit is exactly patient in addition might be revealed away by the doctor.The medical insurance system of external a lot of countries stipulates that all the doctor will just can ask for expense to insurance company with inspection record at present, and the laws and regulations of our national this respect are also perfect gradually.Present China's doctor-patient relationship anxiety, malpractice also is on the increase, the patient privacy data are revealed also often sees report, therefore must be above technological means prevents the generation of these situations.
To sum up, provide a kind of robust, stable, reliable means to come identification patient's identity, thereby patient's passing inspection record can correctly be stored, patient's inspection record is safer, for patient provides better service, is very significant.

The specific embodiment
Describe each related detailed problem in the technical solution of the present invention in detail below in conjunction with drawings and Examples.Be to be noted that described embodiment only is intended to be convenient to the understanding of the present invention, and it is not played any qualification effect.
Fig. 1 is the block diagram of system that has the ultrasonic diagnostic equipment of Fingerprint Identification Unit, and wherein except Fingerprint Identification Unit, other part is the standard configuration of traditional ultrasonic diagnostic equipment, only does brief description here.Transducer (also being probe) is hyperacoustic device that transmits and receives, and is generally made by piezoelectric, can convert electrical energy into acoustic energy, also can change conversely; Radiating circuit sends the signal of telecommunication to transducer under the coordination of controller, be converted to ultrasonic emitting by transducer and go out; Receiving circuit is responsible for receiving transducer and is passed the echo signal (being converted to the signal of telecommunication by transducer) come, and amplify, processing such as digital to analog conversion; Wave beam is synthetic to carry out dynamic focusing and dynamic aperture processing to the echo signal on the different directions, and it is synthesized together; The signal that signal processing and image form wave beam after synthetic carries out processing such as noise suppressed, envelope detection, logarithmic compression, digital scan conversion, forms the image that is easy to show at last; Display can be common CRT monitor or liquid crystal display etc., is responsible for image is shown and the demonstration of some user interfaces; Controller is responsible for all other parts are controlled and coordinated, it can be a circuit, also can be an embedded device or a microcomputer, the controller of present most of digital ultrasound diagnostic device all be embedded device or the microcomputer that has operating system; Keyboard is the user input of controller, and it is mutual to come with controller for a kind of means easily of user, and trace ball is all arranged on the keyboard of present most ultrasonic diagnostic equipment, is used for realizing the function with the mouse equivalence, and is user-friendly.Fingerprint Identification Unit can use very sophisticated in the market product, be connected on the controller by multiple interfaces, these interfaces can be prior USB interface, pci interface, IEEE1394 interface, parallel port, serial ports, wired network interface, radio network interface etc., also can be following other interface that occurs, be used for controller and Fingerprint Identification Unit and carry out transfer of data.Although clearly do not indicate among the figure, the Fingerprint Identification Unit of mentioning here also can directly be embedded on the keyboard, and is mutual by the Interface and Controler of keyboard again.Had after the Fingerprint Identification Unit, the program in the corresponding controller must be made corresponding modification, and the back can provide specific description in conjunction with Fig. 2 and Fig. 3.
Among the present invention Fingerprint Identification Unit is integrated in traditional ultrasonic diagnostic equipment, because fingerprint has uniqueness, and be patient's self biological characteristic, at any time carry, not replaceable, therefore be very suitable for the patient status is carried out identification, and correctly inquire about patient's passing inspection data and medical history taking, just can provide finger print information when having only patient on the scene in addition, therefore the doctor also can only be the information that could visit patient when patient is checked, like this with regard to problems such as the preservation that solved insurance fraud, malpractice protocol effectively, patient privacies.The present technology of Fingerprint Identification Unit is very ripe, and volume can be done very for a short time, therefore can be embedded on the keyboard of ultrasonic diagnostic equipment.Also can be directly connected on the controller in addition, utilize on the controller present interfaces or corresponding interface is set on controller to get final product by various interface.In keyboard, still kept traditional " New Patient " key (button of newly-built patient's inspection record), the patient who is very difficult to recognize by those special people with disabilitys that do not have fingerprint or fingerprint is reserved.
Add after the Fingerprint Identification Unit on traditional ultrasonic diagnostic equipment, the program in the controller must be made corresponding modification.As shown in Figure 2, the step of collection patient ultrasonoscopy is as follows:
51: gather patient's fingerprint by Fingerprint Identification Unit;
52: with all fingerprint comparisons among the fingerprint that collects and the data base;
53: controller judges whether to find the fingerprint of coupling, if find then execution in step 54, otherwise execution in step 57;
54: load the pairing patient information of coupling fingerprint automatically;
55: the passing ultrasonic examination image that loads this patient;
56: load this patient's records such as passing medical history, execution in step 511 then;
57: the dialog box that ejects newly-built patient's inspection record;
58: the doctor is manual input patient information in described dialog box;
59: deposit the fingerprint that collects in data base;
510: the patient information foundation of described fingerprint that collects and input is related, and execution in step 511 then;
511: collection patient's ultrasonoscopy is also diagnosed;
512: ultrasonoscopy and finger print information are preserved in the lump and finished.
In step 51, need with traditional ultrasonic diagnostic equipment that the input patient information is different earlier, a finger print information that only needs here to gather patient gets final product, and patient only need be under doctor's prompting, and is the finger of oneself inswept getting final product on fingerprint capturer, very convenient.In step 52, the finger print information that controller obtains gathering, and with the data base in all finger print information comparisons of patient in the past of storing, the kit that fingerprint comparison can adopt fingerprint capturer to provide.In step 53, the fingerprint that controller judges whether to find in the data base and the new fingerprint of gathering is complementary if find, then changes step 54 over to, otherwise changes step 57 over to.Therefore in step 54, controller can conclude that current patient had inspection record in the past, loads this patient's information such as name, sex, ID automatically.Wherein id information is particularly important, in the DICOM international standard, and the identity that patient's id information should this patient of unique identification, all inspections (Study) of patient all must be correctly be associated with patient's ID.Therefore in step 54, current patient's ID directly obtains from the data base, and assignment once more.In step 55, controller is the passing ultrasonic examination image of inquiry and loading current patient from the data base automatically, comprises still image, dynamic multiple image, measurement result etc.In step 56, controller is records such as the passing medical history of inquiry and loading current patient, audit report from the data base automatically.In step 57, because the finger print information that in the data base, does not find the fingerprint with current patient to be complementary, therefore controller can conclude that current patient did not have inspection record in the past, ejects traditional " New Patient " dialog box on display, allows the doctor import patient's information.In step 58, the doctor uses keyboard to import information such as patient's name, age, date of birth by hand, patient's ID generates a unique number automatically by system, in this step, even input error has appearred in the doctor, do not influence patient status's identification, because system is when the inquiry patient information yet, be not adopt these conditions to inquire about, but directly come matching inquiry with finger print information.In step 59, controller will deposit the patient's that newly gathers finger print information in data base, in order to can correctly mating fingerprint when this patient checks again next time.In step 510, controller is related with foundation between the patient information of the finger print information gathered and doctor's input, so that can use finger print information to inquire about corresponding patient information.In step 511, the doctor uses the function of conventional ultrasound diagnostic device, gathers patient's ultrasonoscopy, measures, and provides diagnosis report etc.In step 512, controller is embedded into patient's finger print information in the ultrasonoscopy of each collection, if the ultrasonoscopy of gathering uses the DICOM form of standard to preserve, finger print information can be used as a privately owned label and is embedded in the DICOM file so, other does not support the DICOM software of embedded finger print information can normally open this file and normal the demonstration yet, only neglects embedded finger print information.At last, patient's current inspection finishes.
In medical diagnosis, swap data is frequent thing between the different ultrasonic diagnostic equipments, so ultrasonic diagnostic equipment should be able to export to the patient data in the system of being stored on the exterior storage medium, also should be able to import the data that miscellaneous equipment is derived from exterior storage medium.In addition, if ultrasonic diagnostic equipment is supported the DICOM international standard, can be transferred on the other equipment of following dicom standard being stored in patient data in the system by network service, also can import to the patient data on the miscellaneous equipment in the system of oneself by network service.Below in order to narrate conveniently, derivation that will be by the network transmission and the derivation by exterior storage medium are referred to as derivation, and importing that will be by the network transmission and the importing by exterior storage medium are referred to as importing.In traditional ultrasonic diagnostic equipment, when importing data, whether this patient that can only rely on conditions such as patient name, sex, date of birth to make up to judge importing is identical patient with existing patient in the system, is not very reliable therefore.Adopted after the Fingerprint Identification Unit, this problem can be well solved.
As shown in Figure 3, the present invention is as follows from the step that other ultrasonic diagnostic equipment that has Fingerprint Identification Unit imports the patient data:
61: from the file that imports, read finger print information;
62: with all fingerprint comparisons among the finger print information that reads and the data base;
63: judge whether to find the fingerprint of coupling, if find then execution in step 64, otherwise execution in step 67;
64: from the file that imports, read the patient information corresponding with the fingerprint of described coupling;
65: the patient information and the pairing patient information of coupling fingerprint that read are merged;
66: the view data that imports is deposited in the data base and is associated end then with the coupling fingerprint;
67: deposit the finger print information that imports in data base;
68: from the file that imports, read patient information and view data;
69: deposit patient information, the view data that reads in data base and related, finish then with the finger print information that imports.
Described importing can import from exterior storage medium (as USB flash disk, portable hard drive, CD, DVD, MO magnetic optical disc, tape etc.), also can import by network service (using standard DICOM agreement or self-defining proprietary protocol).
In step 61, the querying condition such as name, sex that depends on patient with traditional ultrasonic diagnostic equipment is different, because the finger print information with patient has been embedded in the ultrasonoscopy of each collection, so the controller finger print information that only needs read patient from the file that imports gets final product here.In step 62, all of storing among finger print information that controller usefulness is newly read in and the data base are patient's finger print information comparison in the past, the kit that fingerprint comparison can adopt fingerprint capturer to provide.In step 63, the fingerprint that the fingerprint that controller judges whether to find in the data base and newly reads in is complementary if find, then changes step 64 over to, otherwise changes step 67 over to.In step 64, controller can conclude that the patient of current importing had had inspection record in native system, therefore need be merged into the existing patient record of system to the patient data who imports.In this step, from the file that imports, read earlier patient's information such as ID, name, sex, date of birth.In step 65, that patient's who is complementary with importing patient finger print information in the controller acquisition system information is carried out the merging of patient information then.If the ID of the patient information item that mates in the patient information item that imports and the system is different, then system generates a new ID automatically, and makes the ID of these two patient informations be equal to this newly-generated ID.If, make the field of certain patient information in one, not have because the doctor imports the error of patient information, in other one, have, then fill that does not have automatically.If the field of certain patient information (such as patient's name) is different in two, show that then wherein a Xiang doctor imports wrong, can eject dialog box this time allows the doctor revise this mistake, a conduct also can directly getting wherein is correct, the attention of reresenting the doctor after all merging is finished.In step 66, controller reads information such as ultrasound image data from import file, deposits among the data base of system, and is associated with corresponding finger print information, uses for later inquiry.In step 67, because the finger print information that in the data base of system, does not find the fingerprint with current importing patient to be complementary, therefore the controller patient that can conclude current importing does not have inspection record before in native system, and the finger print information that directly will import patient deposits among the data base of system.In step 68, controller reads data such as information such as patient's ID, name and ultrasonoscopy from the file that imports, if patient ID is identical with existing patient ID in the system, system generates a new patient ID automatically.In step 69, the patient information that controller obtains previous step suddenly, view data etc. deposit the data base of system in, and related with the finger print information foundation of step 67, use in order to later inquiry.At last, importing data procedures finishes.
The above; only be the specific embodiment among the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with the people of this technology in the disclosed technical scope of the present invention; can understand conversion or the replacement expected; all should be encompassed in of the present invention comprising within the scope, therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
Scheme provided by the invention is except being applied to the ultrasonic diagnostic equipment, making an amendment slightly also can be applied to the intelligent medical equipment of any patient status's of needs identifications such as CT, nuclear magnetic resonance, NMR.
