Technical Field
The invention relates to the technical field of medical treatment, in particular to a nursing PDA based on facial recognition and fingerprint recognition and a using method thereof.
Background
The identity recognition of the patient runs through the whole medical care activity, the correct recognition of the identity of the patient plays a crucial role in guaranteeing the medical care safety of the patient, and the importance of medical workers at home and abroad is never ignored. The Chinese physician association has been the first of the safety targets of patients, and domestic hospitals all have a patient identification system and various procedures and measures for effectively identifying the identity.
The wrist strap is used as an identification mark for accurate and reliable patient identity and is widely applied to various domestic hospitals. PDA has become increasingly popular in large hospitals as a result of the development of electronic information technology. At present, a plurality of PDA for nursing in the market support one-dimensional code and two-dimensional code scanning, so that the PDA can generate information correlation with a wrist strap and is used for patient identification. However, the situation that the patient has poor compliance when carrying the wrist strap, the wrist strap is lost, the wrist strap is worn, the information of the wrist strap is wrong, the outpatient does not have the wrist strap, and the like is considered, and how to improve the identity recognition effectiveness and the safety of the patient needs to be solved urgently.
With the progress of the face recognition technology and the fingerprint recognition technology, the method has been widely applied to multiple fields of mobile communication, payment and the like as a means with high safety performance and high recognition efficiency. The prior patent application No. 201720159694.2, filed as 2017.02.21, entitled "medical PDA device", relates to a medical PDA, which comprises a PDA body and a PDA shell, and mainly expands the functionality of the prior PDA. It should be mentioned that, the PDA body in this patent includes fingerprint sampler, gathers user's fingerprint, and central controller passes through fingerprint identification user's identity, and only after confirming user's identity, the touch operation panel just can unblock and supply the user to use, prevents that other irrelevant personnel from browsing, deleting or modifying the data, prevents the leakage of relevant privacy information such as patient's case history. The above patent enriches the functions of the PDA, but does not address the patient identification deficiencies.
Disclosure of Invention
Aiming at the problems of the existing patient identification defects and the existing technology defects, a nursing PDA based on the combination of facial identification and fingerprint identification is provided.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

Compared with the prior art, the invention has the beneficial effects that:
the invention provides a nursing PDA based on facial recognition and fingerprint recognition and a using method thereof, wherein the facial recognition is carried out through an image acquisition module so as to realize the acquisition and rechecking of facial information of a patient; the wrist strap can be used as an alternative under the conditions that the patient has poor compliance when carrying the wrist strap, the wrist strap is lost, the wrist strap is worn, the information of the wrist strap is wrong, and the outpatient has no wrist strap; or the alternative scheme after the technology is mature, the accuracy of the identification of the patient is ensured, and the treatment safety of the patient is guaranteed.
Furthermore, the PDA body is provided with a touch screen display module, a capacitive touch screen is adopted, and the PDA body can be operated by hand touch and an electronic pen to process medical orders, enter nursing file information and the like; and may invoke keyboard input functionality.
The beneficial effect of adopting the further scheme is as follows: the display module can carry out information output and data writing, and the keyboard is called to facilitate data input of a user.
Furthermore, the image acquisition module carries out image preprocessing, laser scanning head, image sensing and the like through the camera, so as to realize facial recognition and scanning of the two-dimensional code and the bar code.
The beneficial effect of adopting the further scheme is as follows: the two-dimensional code or the bar code compatible with the existing wrist strap identity recognition is used for scanning and obtaining the identity information, so that the identity of a patient is checked, an identity recognition mode is expanded, the facial features of the patient are effectively collected at first, and a data module is prestored. And in the subsequent treatment and nursing process, corresponding functional operation is carried out, the identity of the patient is identified by starting facial identification, then the facial identification of the patient is carried out and verification is carried out, and if the facial features are consistent with the pre-stored features, the identity of the patient passes the identification, and corresponding treatment and nursing operation is carried out.
Furthermore, fingerprint identification module utilizes push type fingerprint sensor, can feel the little change that blood flows in the finger blood vessel, carries out the collection and the discernment of fingerprint.
The beneficial effect of adopting the further scheme is as follows: through identity authority setting, on one hand, the touch display module can be unlocked for the user to use by confirming the identity of the user (mainly a nurse), so that other irrelevant personnel are prevented from browsing, deleting or modifying data, and the leakage of relevant privacy information such as medical records of patients is prevented; and on the other hand, the identity of the patient is checked, the fingerprint characteristics of the patient are effectively collected firstly, and a data module is prestored. And in the subsequent treatment and nursing process, corresponding functional operation is carried out to start the fingerprint identification identity, then the fingerprint identification of the patient is carried out and verification is carried out, if the verification fingerprint is consistent with the pre-stored fingerprint, the identification of the patient is passed, and corresponding treatment and nursing operation is carried out. In addition, whether the finger is a living body can be judged according to the blood flow micro-change, so that the fingerprint unlocking can be prevented by using a model with the fingerprint.
Further, the communication module comprises a network port, a wifi module and a bluetooth module.
The beneficial effect of adopting the further scheme is as follows: the invention realizes the interactive functions of internet access, communication and the like, so that the collected information can be transmitted, and under the condition that the storage function of a single PDA is limited, new data for treating and nursing patients are downloaded by the data updating function in different time periods, and the old data are emptied.
