the alarm prompt component is connected with the main control circuit board and is used for carrying out alarm prompt under the control of the monitoring program;
the battery is used for supplying power to the monitoring device.
The working principle of example 1 is explained in detail below:
in clinical treatment, nursing operations of nursing personnel can involve multiple aspects, such as oxygen supply through a single nasal catheter, intravenous infusion with a venous retention needle, blood transfusion, and the like, and the operation flow of the blood transfusion is exemplified in the embodiment.
After the nursing staff is on duty, before nursing operation, wear wearable nursing operation flow monitoring device earlier. In order not to affect the operation of the nursing staff, preferably, the monitoring device is worn at the position of the arm upper arm of the nursing staff, a fastening piece is arranged on the shell of the monitoring device, the shape and the material of the fastening piece are not limited, and the fastening piece can be a cloth binding belt or a buckle ring with an opening. When the device is worn, the bottom of the monitoring device is attached to the position of biceps brachii or triceps brachii, and the monitoring device is fixed well through a cloth bandage or a retaining ring, so that the monitoring device cannot generate large displacement in the operation process of nursing staff. The caregiver needs to pay attention to the fact that the monitoring device is held with the end mounted with the camera facing his wrist, rather than his shoulder.
After the monitoring device is worn, a nursing staff turns on a switch of the monitoring device, the monitoring device starts to be electrified to work, and a main control circuit board in the monitoring device starts to load a system and operate a monitoring program. The system is a WINCE embedded system, and a monitoring program is developed by combining various hardware of the monitoring device. After the monitoring device starts working, the monitoring program controls the image acquisition module to start image acquisition and performs image identification on the acquired image. In the present embodiment, the image capturing module is exemplified by a camera. The principle of the monitoring program for image recognition is that the collected image is subjected to characteristic quantity extraction, and then is compared with a standard image sample stored in the monitoring program to obtain an image recognition result.
In order to ensure that the camera can shoot the operation of the hands of the nursing staff all the time and monitor whether the operation of the nursing staff meets the standard flow, the camera on the monitoring device is arranged on a base, and the base is rotatable, so the camera can also rotate along with the rotation of the base. Preferably, the magnitude of the rotation is not less than 135 degrees. The monitoring program is provided with a target following function, and a following object of the target following function is arranged as the wrist of the person. When the monitoring device starts to work by electrifying, the monitoring program can identify the initial image shot by the camera at the moment, and if the wrist of a person is identified in the middle of the image, the monitoring program controls the angle of the camera to keep still; if the wrist of the person is not in the center of the recognized image, the monitoring program can control the camera to rotate, the camera can shoot in real time in the rotating process, the monitoring program can process the shot image in real time to recognize the image until the wrist of the person is in the center of the recognized image, and the monitoring program controls the camera to stop rotating. In order to achieve both the following speed and the following accuracy in the present embodiment, it is preferable that the angular speed of the camera rotation be 1 to 3 °/second when the target following is performed. Meanwhile, in the whole working process of the monitoring device, the target following function is always started, if the monitoring device generates smaller displacement due to the action of nursing staff, the center of an image shot by the camera is not aligned with the wrist of a person, the monitoring program can correct the angle of the camera in time, and the camera is controlled to rotate. Therefore, the camera can shoot the operation of the nursing staff no matter where the hands of the nursing staff are positioned during operation.
When the nursing staff carries out the blood transfusion to the patient, look over the paper medical advice that the doctor prescribed an order and printed at first, then print out clear complete detection bar code according to the medical advice requirement. The action of nursing staff can be shot to the camera, through image recognition, judges whether nursing staff has the doctor's advice of looking over. Meanwhile, the camera can also shoot the operation of printing the detection bar code by the nursing staff. If the monitoring program does not recognize that the nursing staff has the action of checking the medical advice or does not recognize that the nursing staff has the action of printing the detection bar code, the monitoring device can remind the nursing staff of misoperation. Specifically, the monitoring program carries out alarm prompting by controlling the alarm prompting component, and the alarm prompting mode can be that the vibration motor vibrates to drive the monitoring device to vibrate; or the monitoring program sends out warning sound by controlling the loudspeaker.
Then, the nursing staff can check the application form information and the bar code information and paste the checked bar code information on the test tube. The nursing staff holds the test tube to the patient bedside to execute blood sampling medical advice, checks the information on the wrist strap of the patient and the information on the detection bar code, and confirms that the identity of the patient is correct. Before blood sampling, the nursing staff should wear the gloves. The nursing staff collects the blood of the patient into the test tube by using the needle as a blood sample, and then turns the test tube upside down and mixes the blood sample three times. After the collection is completed, the nursing staff checks the information on the bar code of the test tube filled with the blood sample and the information on the wrist strap of the patient again, and then checks whether the information on the blood transfusion application form is consistent with the two information. Finally, a nursing staff logs in a hospital management system to confirm the blood sampling information and informs a security center to send for inspection through the system; for emergency blood samples, the transfusion department is notified by telephone and a special person is scheduled for the examination.
When the nursing staff carries out the operation process, the camera continuously shoots the operation of the nursing staff, and the shot video image is subjected to image recognition and comparison through a monitoring program. In the monitoring program, video images of standard operation processes are stored, and a plurality of standard operation single-frame images of key operations are extracted from the video images. The monitoring program processes the shot video image and divides the video image into a plurality of actual operation single-frame images. And comparing the actual operation single-frame images with the standard operation single-frame images to judge whether the actual operation meets the requirements of the standard operation. Specifically, the monitoring program divides the video image captured by the camera into 24 single-frame images according to the video of 1 second, and then sequentially performs image recognition and image comparison on the 24 single-frame images according to the time sequence. In image recognition and image comparison, in order to improve efficiency, different feature quantities are selected according to different steps in an operation flow, and only the feature quantities are recognized, rather than the whole single-frame image.
For example, when the monitoring program determines whether the caregiver checks the paper medical advice that the doctor has issued and printed, the feature quantity of the image recognition is selected as the time when the wrist rotation angle and the wrist rotation angle are kept unchanged when the paper medical advice is held by the hand of the caregiver and the hand. The image recognition function of the monitoring program can recognize that paper medical orders are taken from hands of nursing staff from a certain frame of image in multiple frames of actual operation images, the wrist of the nursing staff starts to rotate by a certain angle in multiple next single-frame images in sequence to enable the paper medical orders to face the face of the nursing staff, and the number of the single-frame images with the wrist rotation angle basically unchanged is 24 or more. If the image recognition function of the monitoring program recognizes a plurality of single-frame images containing the content and the number, the nursing staff is indicated to take the paper medical advice, and the paper medical advice is directed to the face of the nursing staff for more than 1 second, which indicates that the nursing staff views the medical advice and completes the standard process operation of viewing the paper medical advice which is prescribed and printed by the doctor.
For another example: when the monitoring program judges whether the nursing staff attaches the bar code information to the test tube or not, and when the nursing staff identifies whether the bar code information is attached to the test tube or not, the characteristic quantity of the image identification is selected as the test tube, the bar code and the hand of the nursing staff. In the image recognition function of the monitoring program, a test tube is taken from one hand of a nursing staff from a certain frame of image in a plurality of actual operation images, a bar code is taken from the other hand of the nursing staff in sequence in the next single-frame images, the hand of the nursing staff holding the bar code moves to the position of the test tube, and the bar code is pasted on the test tube by the hand of the nursing staff. If the image recognition function of the monitoring program recognizes a plurality of single-frame images containing the content, the nursing staff is indicated to finish the standard process operation of attaching the bar code information to the test tube.
When the nursing staff finishes collecting the blood sample of the patient, the operation of blood taking and blood transfusion is carried out next.
The blood sampling operation is as follows: the nursing staff prints the blood taking list according to the medical advice and confirms that the consent is signed; nursing personnel monitors and records the vital signs of a patient, and the vital signs are mainly body temperature, pulse, blood pressure and the like; the nursing staff informs the patient to prepare for transfusion, and the nursing staff establishes a venous channel; the blood taking personnel takes blood by taking a blood list and carrying a blood taking box; the blood taking personnel checks the blood taking list, the blood application list, the blood generation list and the blood bag label information and requires consistency; blood sampling personnel check the blood type, dosage, appearance quality, expiration date and blood matching result; the blood taking person signs the blood taking list; the two parties of taking and sending blood go out the sound together to check the relevant information, including the name, ID, blood type, age, department, blood bag number, dosage, validity period, blood matching result, etc. of the patient, and the blood sending is finished after the confirmation is correct; after the blood is taken, the blood-taking personnel need to return to the department immediately and perform infusion on the patient within 30 minutes.
The operation of the blood transfusion is as follows: the blood taker and the nursing staff check the medical advice list, the blood information and the blood appearance quality together; the nursing staff confirms the time for monitoring the vital signs of the patient, and if the time exceeds 15 minutes, the monitoring needs to be carried out again and the monitoring table is filled in time; a nursing staff establishes a blood transfusion channel and uses the antiallergic medicine according to the advice; two nursing personnel stand beside the patient bed to know whether the patient has a blood transfusion history and special transfusion requirements and execute blood transfusion medical advice; the two nursing staff make a sound together to check the information of the application form, the blood production form, the wrist strap and the blood bag and carry out double signature; the nursing staff need to gently turn upside down and shake the blood evenly before transfusion, and strictly perform aseptic operation, and blood transfusion is started within 30 minutes after blood sampling; within 15 minutes from the start of transfusion, the caregiver observed at bedside, infused slowly, and again measured and recorded vital signs at 15 minutes; the nursing staff carries out propaganda and education on the adverse reactions of blood transfusion to the patient and confirms that the blood transfusion cautions are issued to the patient; monitoring and recording the vital signs of the patient at the 60 th minute after the transfusion is finished; the nursing staff stores the blood transfusion related records into the medical record completely and timely; the transfused blood bag is marked with department, date, name of recipient, and is delivered to the department of transfusion within 24 hours and well registered.
In the whole process of blood taking and blood transfusion of a nursing staff, the monitoring device shoots the actual operation of the nursing staff in the whole process, and judges whether the actual operation of the nursing staff conforms to standard operation or not through the image recognition and image comparison functions of the monitoring program, wherein the actual operation of the nursing staff comprises the flow sequence of operation and the action effect of operation.
In this embodiment, ABS plastics can be selected for use to monitoring devices's shell, and ARM industrial control board can be selected for use to the master control circuit board, and HJ-VB2MP01 can be selected for use to the camera, and the optional electrodynamic type loudspeaker of loudspeaker, vibration motor can select for use N20PA, and the polymer lithium cell of 20000mAh capacity can be selected for use to the battery. The monitoring device is preferably in the shape of a long strip box with the size of about 200 multiplied by 100 multiplied by 50mm, so that the monitoring device can be worn conveniently.
Example 2
During the blood sampling, blood sampling and blood transfusion processes, some steps of the standard operation flow require a nurse, a blood sampling person, a blood sending person or a patient to carry out conversation, for example, during the blood sampling process, the blood sampling and blood sending parties need to go out the same voice to check related information, including the name, ID, blood type, age, department, blood bag number, dosage, validity period, blood matching result and the like of the patient; during the transfusion process, nursing personnel can teach patients about adverse reactions of transfusion, and the like.
In order to solve the above technical problem, a voice acquisition module is installed on the monitoring device and is connected with the main control circuit board for voice acquisition in further optimization based on the embodiment 1. And the monitoring program performs voice recognition on the collected voice, and judges whether the operation of the nursing staff meets the standard operation flow regulation or not according to the recognition result. In the present embodiment, the voice acquisition module is exemplified using a microphone.
Specifically, the monitoring program has a voice recognition function, and the microphone has sound receiving sensitivity within a certain range, so that conversation between a monitoring device wearer and a person can be collected. In this embodiment, the monitoring device wearer includes a caregiver and a phlebotomist. The microphone can collect the talking of the nursing staff to the patient and the conversation with the patient; the dialog between the phlebotomist and the phlebotomist can also be collected. The monitoring program sequences the operation actions and voices to be judged according to the time axis flow direction of the standard operation flow, and a section of voice conversation is preset to follow one operation action. For example, the monitoring program judges that the blood drawing person performs the actual operation action of signing on the blood drawing sheet through image recognition and image comparison; the following process should be to take and give a sound to check information together with the blood, at this time, the monitoring program controls the microphone to be started, and performs voice collection and voice recognition. The voice recognition does not need to speak all dialogues to carry out recognition and judgment, and only needs to recognize whether preset keywords appear in the dialogues and whether voices of two different people exist. Such as: when the two parties of blood taking and sending go out the voice to check the information together, the keywords of the voice recognition can be selected from name, ID, blood type, age, department and the like; whether two different persons speak is identified, waveforms of front and back two sections of voice in a conversation can be compared through a voiceprint identification technology, and the fact that the waveforms are inconsistent indicates that the two different persons speak is indicated.
When the monitoring program monitors that the nursing staff does not operate according to the preset standard flow, and a certain step which should speak is not speaking, the monitoring device can give an alarm prompt to remind the nursing staff of careless operation.
Example 3
In the nursing operation, operation steps which need to be completed by two nursing personnel together may occur, for example, two persons are needed to check the bar code of the blood sample and the wrist strap information of the patient, and two persons are needed to sign and confirm; two persons are required to check the wrist strap and detect the bar code information together, confirm that the identity of the patient is correct, and the like. During this process, the two caregivers, a and b, each wear a monitoring device; at this time, the actual operation of the nursing staff A and B is judged according to the standard operation flow preset in the monitoring program, and the misjudgment may occur. The reason for misjudgment is that when the operation of a certain step is performed by the nursing staff A, the monitoring device of the nursing staff B cannot acquire the operation action of the nursing staff A because the camera is aligned with the wrist of the nursing staff B, and if the step is not preset to be performed by the nursing staff A, the monitoring device of the nursing staff B misjudges and alarms.
In order to solve the technical problems, the method is further optimized on the basis of the embodiment 1 and the embodiment 2, a judgment process is preset in a monitoring program, after the operation sequence of two nursing personnel in cooperation is determined, the operations, including actions and conversations, of the two nursing personnel are monitored respectively, if the operation of any one person does not accord with the standard process, a monitoring device worn by the nursing personnel with out-of-standard operation gives an alarm, and a monitoring device worn by the other nursing personnel does not give an alarm.
Specifically, when a nursing staff A and a nursing staff B cooperate together to complete a certain step, the first monitoring device worn by the nursing staff A monitors the operation of the first monitoring device, the second monitoring device worn by the nursing staff B monitors the operation of the second monitoring device, and the first monitoring device and the second monitoring device can identify the voices of the nursing staff A and the second monitoring device in the operation process. The monitoring program determines the sequence of operations of the two caregivers in cooperation according to the first operation of the two caregivers. For example, the whole step is composed of operation one, operation two, and operation three, and in the actual operation, whether the operation is performed by the first or the second is pending. If the first operation is performed by the nail, the nail monitoring device monitors that the first operation is completed by the nursing staff nail, and the nail monitoring device does not give an alarm; the monitoring device B can judge that two nursing staff finish the step together according to a preset flow, and the monitoring device B cannot give an alarm at the moment; however, the second monitoring device can judge whether the actual operation of the second nursing staff member meets the regulations of the standard process according to the subsequently monitored images and voices. Therefore, according to the judgment flow preset in the nursing operation monitoring program, the operation sequence of two nursing staff in the matching process can be determined, the operation of the two nursing staff including actions and conversation can be monitored, if the operation of any one person is not in accordance with the standard flow, the monitoring device worn by the nursing staff with out-of-standard operation can give an alarm, and the occurrence of false judgment and false alarm can be avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
