Description

  The present invention uses blood vessel image information obtained by a medical staff so that a blood vessel hidden behind the skin is difficult to see when a needle is inserted by a procedure such as injection, infusion, blood transfusion, and blood sampling. The present invention relates to an apparatus for confirming the patient himself and the treatment part on the spot when performing the treatment.

  Conventionally, in the medical field, injecting needles, infusions, blood transfusions, and blood collection needles into a patient's blood vessels are performed by winding a tourniquet around an arm or the like to expand the blood vessels so that the blood vessels can be seen with the naked eye. Is normal. However, blood vessels are difficult to see in many patients such as infants, elderly people, and those with a lot of subcutaneous fat, and medical workers rely on the feeling of touching with their fingers to insert and remove the needle tip several times and conduct a search. Many things can be seen. Since there are nerves around the blood vessels, it is desirable to insert the needle once without damaging them.

Many proposals have been made for devices that perform blood vessel search from this point of view and assist needle insertion.
Patent Documents 1 to 3 are proposals for visualizing these blood vessels.
Looking around, the identity of the patient remains the same as before as the patient is asked for his name and date of birth, but using a paper bracelet with his name on his arm.
I think these are quite effective, but there are still inconveniences that should be assisted in that they are not effective until just before the treatment, they cannot cope with impersonation, and there is no evidence of confirmation.

The stored blood vessel image data is collated and compared by the operative portion blood vessel image collating means, and a collation result as to whether or not they match is output, and the result can be saved. Hereinafter, description will be made using examples.

FIG. 1 is a diagram showing an embodiment of a patient treatment part confirmation apparatus using treatment part blood vessel image information according to the present invention.
In 1-A, the patient operation unit confirmation apparatus 100 is used by a medical worker 101 such as a doctor or nurse (in the example of this figure, the head is mounted on the head, but the head mounted form is used). Do not stick). A medical worker 101 has a surgical instrument 102 such as a syringe, a dropper, a blood collection device, and a blood transfusion device, and inserts the needle of the surgical instrument 102 into a surgical unit 103 such as a patient's arm. In that case, the patient treatment part confirmation apparatus 100 has the structure demonstrated below and can be operated.

In 1-B, the illumination light source 105 is at least an infrared light source, particularly a near-infrared light source (wavelength 760 to 2000 nm), and is irradiated toward the surgical operation section 103 of the patient. As the light source, a visible light source can be used in combination. In this case, the same image as that with the naked eye can be acquired. Illumination light from the illumination light source 105 is reflected by the treatment unit 103, and the reflected light is received by the image acquisition unit 106 to obtain a treatment unit image. When the illumination light is infrared light, the infrared light is absorbed by blood flowing in the blood vessel, so that the reflected light has a light intensity lower in the blood vessel portion than in the surrounding portions. Therefore, the image acquired by the image acquisition unit 106 for reflected light is a reflection of a blood vessel image. The image acquirer 106 can obtain a blood vessel image by removing visible light noise by using an infrared light camera or a camera equipped with an infrared light transmission filter in front of the camera. In the case where the visible light camera and the camera are used together, it is also possible to switch and use an infrared transmission (visible light blocking) or infrared blocking (visible light transmission) filter.

The treatment part image acquired by the image acquisition unit 106 is sent to the image processing unit 107. The image processor 107 includes an image calculation unit 108 and an image memory 109. In the image calculation unit 108, if there is a visible light image, the obtained treatment unit image is combined with an infrared light image, So-called image processing such as intensity (brightness) adjustment processing, contrast enhancement processing, contour enhancement processing, and coloring is performed so that the image size and orientation for display on the display device 110 can be adjusted and the blood vessel portion of the image can be easily seen. It is also possible. A medical worker performs a procedure such as inserting a needle while viewing the blood vessel image displayed on the display 110.

Immediately before this treatment, essential and important means and functions of the image calculation unit 108 are in the treatment unit blood vessel image collating unit 111, and perform blood vessel image collation.
Prior to performing the treatment, the medical staff uses the patient identification information input means 104 to input patient identification information.
For this purpose, when there is no input patient identification information, it is preferable to perform display or audio output prompting the input of patient identification information every time the image acquisition unit 106 acquires a surgical part image.
A caution mark may be displayed on the display screen.
Various forms can be taken to input patient identification information. For example, a patient's name, date of birth, registration card symbol and other registration symbols associated with the individual patient are entered, but the card presented by the patient and the verification tag worn by the patient are entered from the keyboard. The patient recognition code affixed to the patient's arm is input as an image from the image acquisition unit 106 and input by a reader (bar code reader, QR code reader, IC card reader, etc.) from Many forms such as input in the form of identification information can be taken. The patient identification information is stored in the patient identification information memory 116 via the controller 112. In the case of saving, it is performed in association with the treatment part image acquired by the image acquisition unit 106 or the treatment part image obtained as a result of processing by the image processing unit 107.

When the patient identification information is input, the controller 112 is instructed by the patient identification information from the stored blood vessel images stored in advance in the image memory 114 of the patient information file 113 (previously or stored during the previous operation). The selected image data is selected as specific image data and sent to the image calculation unit 108 of the image processor 107. In the image calculation unit 108, the surgical part blood vessel image collating unit 111 therein collates the specific image data with the surgical part blood vessel image data currently acquired by the image acquisition unit 106 and determines whether or not they match. The result is output at the collation result output unit 115 through the controller 112. The collation result output unit 115 can be expressed in sound or visually expressed as an image or a character on the display unit 110.

In the image data collation of the surgical unit blood vessel image collating means 111, the entire acquired image data may be collated, but since it is necessary to collate the blood vessel image data, the blood vessel contour and branch, the arrangement of the continuous blood vessel line, Data of feature points such as the interval and the center line of the blood vessel line is taken up in consideration of the matching probability, and the matching can be performed at the minimum. In order to grasp these feature points, it is effective to cause the image calculation unit 108 to perform so-called image processing.
The collation result can be used as post-operative evidence (traceability) by saving it in the patient information file 113.

  In the above, the controller 112 includes the patient identification information input unit 104, the illumination light source 105, the image acquisition unit 106, the image processing unit 107, the display unit 110, the patient identification information memory 116, and the patient information file in addition to the functions described above. It controls operations such as data transmission / reception to / from 113, and usually has a computer and a processing program. Other than that, a power source and the like are not shown, but naturally they are included as devices.

FIG. 2 is a diagram showing an image at the time of using the patient operation part confirmation apparatus using the operation part blood vessel image information according to the present invention.
The medical staff uses the patient treatment unit confirmation device 100 to perform treatment. The image of the surgical unit acquired from the image acquisition unit 106 or the surgical unit blood vessel image data 201 processed by the image processor 107 is stored in the stored blood vessel image data 202 from the patient information file 113 by the surgical unit blood vessel image collating unit 111. The comparison result is output. In this example, since both blood vessel image data are different, a voice or display of “The blood vessel pattern is different. Please check.” Is displayed. As a result, the medical staff stops the treatment and confirms it. It is also effective to notify the prohibition of the operation according to the collation result, and to prevent the blood vessel image from being displayed until it is confirmed and canceled.
Of course, since both blood vessel image data are usually the same, an output such as “No problem was found in the matching result” is usually output.

FIG. 3 is a view showing one embodiment of a flow diagram showing the operation of the patient treatment unit confirmation apparatus using the treatment unit blood vessel image information according to the present invention.
The medical worker uses the patient treatment unit confirmation apparatus 100 to perform a treatment unit blood vessel image acquisition 301. The image data is saved as it is, or temporarily after being processed by the image processor 107, as the operation part blood vessel image data 201 in the image memory 109 (the operation part blood vessel image data storage 302 in the image memory).
The controller 112 checks in the patient identification information memory 116 whether the patient identification information is input. If there is no input information of the patient identification information, the patient identification information input prompt 304 is output as an audio output or an output of the display 110. Do. When the patient identification information input 305 is performed, the information is stored in the patient identification information memory 116 via the controller 112. Next, in the stored blood vessel image data acquisition / mounting 306 from the patient information file, the stored blood vessel image data 202 of the patient is extracted from the patient information file and mounted on the surgical unit blood vessel collating means 111. Similarly, in the surgical section blood vessel image data acquisition / mounting 303 from the image memory, the surgical section blood vessel image data 201 corresponding to the patient identification information is loaded from the image memory 109 to the surgical section blood vessel collating means 111 and the surgical section blood vessel collation 307 is performed. It is. The collation result output 308 is performed as audio output or visual output on the display 110. Thereafter, a collation result storage 309 is made as evidence after the operation and used for history management. The collation result storage 309 is finally performed on the patient information file 113. It should be noted that the use of the same memory for the patient identification information memory 116 and the image memory 109 does not interfere with the idea of the present application.

Of course, a plurality of stored blood vessel information can be stored for one patient. In this case, the stored blood vessel information is sequentially read out and collated, or when the patient identification information is input, By adding a code, it is possible to read and collate only the stored blood vessel information of the corresponding part.

  As described above, the patient operation part confirmation device using the operation part blood vessel image information according to the present invention not only confirms the patient's operation part blood vessel by displaying and hits the operation such as injection, but also before the observation blood vessel image data Can be compared with the stored blood vessel image data of the patient stored in advance, and the identity can be confirmed through the treatment section on the spot, and the result can be notified and stored. Since the treatment can be performed without mistaking the patient, the industrial utility is extremely high.
