Description

  The present invention relates to an inspection system used in a medical facility, and more particularly to a medical inspection system for efficiently performing radiography performed in a radiology department.

  Hospital facilities with many inpatients and outpatients have hospital information systems (HIS) and radiology systems (RIS). The hospital information system manages comprehensive information such as patient personal information, records of each department's consultation department, hospitalization department, medical record information, issuance of medication prescriptions, issuance of examination orders to the examination department, and accounting processing. is doing. Among them, for example, a radiography order to a radiological examination department is performed by inputting to a hospital information system as desired examination contents for each patient from a doctor in charge of a medical department or an inpatient ward.

  On the other hand, in the radiology department, the radiography order issued from the hospital information system is received by the radiology system, and the order information is expanded to the radiography part for each patient, the imaging direction, the patient's body position, etc. indicate. Therefore, a radiology engineer performs specific radiation imaging, for example, X-ray imaging, while confirming the order information displayed on the execution result registration screen. Hereinafter, radiation imaging will be described as X-ray imaging.

For example, for a patient A, an examination order entered into the hospital information system is
(1) Upper abdomen standing (2) Upper abdomen prone (3) Lower abdomen standing (4) Lower abdomen prone (5) Lumbar standing (6) Lumbar supine It will be expanded to the implementation result registration screen in the department system.

  Since the doctor who orders the radiograph describes the radiograph order in the order that the person normally reads the X-ray photograph (or inputs to the terminal), the order may be different from the ease of radiology imaging. . That is, in radiology, when X-ray imaging is performed according to the order of order information displayed on the execution result registration screen, first, the upper abdomen of patient A is imaged in a standing position, and then patient A is placed in a supine position and The patient is forced to change his / her posture every time the image is taken, and the patient A is returned to the standing position and the lower abdomen is imaged, which increases the burden on the patient.

  Therefore, the examination information developed by the radiology system is divided into groups based on the postures that the technicians shoot in a standing position and those that are taken in a supine position in advance, and consideration is given to minimizing patient position changes. I was trying to shoot while. However, if there are still a large number of orders developed, it will not be possible to know what has been taken and what has not been taken, resulting in the inconvenience of being unable to concentrate on the original work of the technician, taking a longer examination time. It was supposed to increase the burden on engineers.

As a solution to this problem, when multiple X-rays are ordered from a doctor, the radiology department changes the imaging sequence so that it can be performed efficiently without burdening the patient. An inspection system that can output the results in an arbitrary order has been proposed (for example, see Patent Document 1).
JP 2000-166908 A

  However, what is described in Patent Document 1 is that when a plurality of X-ray imaging is ordered for a single patient, only the patient is efficiently imaged based on a predetermined conversion table on the radiology side. The imaging order is rearranged so that the work can be performed, and no consideration has been given to the case where X-ray imaging for a plurality of patients is ordered. In addition, no consideration was given to the patient's body condition, that is, whether the patient can walk alone, is in a wheelchair, or is in a stretcher.

  In the present invention, when X-ray imaging is ordered, the present invention considers the physical condition of the patient (that is, the subject) or the number of patients while considering the physical condition of the patient. The object of the present invention is to provide a medical examination system that can reduce the burden and efficiently perform X-ray imaging.

  In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that a reception means for receiving a radiographic order for a plurality of subjects, an input means for inputting information on the physical condition of the subjects, A medical order characterized by comprising imaging order rearranging means for rearranging the imaging order between the subjects according to the physical condition of the subject for a plurality of subjects accepted by the accepting means. Inspection system.

  Further, the invention according to claim 2 is the medical examination system according to claim 1, wherein the radiographic imaging orders of the plurality of subjects received by the receiving means are related to the imaging site and imaging position of each subject. The imaging apparatus further comprises imaging order setting means for setting the imaging order for the ordered radiation imaging based on the key using any one of the imaging directions as a key.

  Further, the invention according to claim 3 is a receiving unit that accepts radiography orders for a plurality of subjects, and radiographing orders of a plurality of subjects that are received by the receiving unit. An imaging order setting means for setting an imaging order based on the radiographic imaging ordered based on any one of the region, imaging posture, and imaging direction as a key, and the imaging order is set by the imaging order setting. For the plurality of subjects, any one of imaging part, imaging position, and imaging direction of the last radiography of the subject who performs imaging before and the first radiography of the subject who performs imaging after that The medical examination system is characterized by comprising imaging order rearranging means for rearranging the imaging order of the subsequent subject so as to be the same.

  As shown in the section of the means for solving the above problems, according to the invention of each claim described in the claims of the present invention, the following effects can be obtained.

  According to the first aspect of the present invention, since the imaging sequence among the subjects is rearranged according to the physical condition of each subject, the medical examination system that is particularly friendly to the subject requiring assistance. In addition, when performing radiography for a large number of subjects, radiography can be performed efficiently.

  According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the imaging sequence of each subject is imaged collectively according to the imaging region, imaging posture, imaging direction, etc. Therefore, it is possible to reduce the burden on the subject by reducing the change of the body position, and to shorten the time required for imaging.

  According to the third aspect of the present invention, it is possible to efficiently perform an examination on the imaging parts, imaging positions, directions, and the like of a plurality of subjects who are in an imaging order without imposing the most burden on the subject. In addition, since the imaging order for each subject is rearranged and the imaging order between the subjects is reset, the patient's body is not forced to change his position many times. Can reduce the burden on In addition, the number of times of changing the position of the bed can be reduced, the burden on the engineer can be reduced, and the inspection efficiency can be improved.

  Hereinafter, an embodiment of a medical examination system according to the present invention will be described in detail with reference to FIGS.

  FIG. 1 shows a system configuration of an embodiment of a medical examination system according to the present invention. What is indicated by reference numeral 1 in the figure is a HIS server of a hospital information system, and many hospital terminals arranged in a medical facility, such as a reception terminal 2, an outpatient terminal 3, a ward terminal 4, a pharmacy terminal 5 The information input from each terminal is collected here. The HIS server 1 is also connected to the RIS server 10 of the radiology system, and an inspection order for the radiology department is issued from the HIS server 1 to the RIS server 10. Then, the contents of the examination order received by the RIS server 10 can be confirmed at the terminals 11, 12... 14 for each radiology client.

  For example, when an examination order for three patients (patient A, patient B, and patient C) has been issued from the HIS server 1, when the terminal 11 of the X-ray imaging room is activated, an order list is displayed as shown in FIG. As shown in FIG. 2, for these three patients, an examination ID, a patient ID, a patient name, and a gender, a photographing menu showing examination contents and information on the patient's physical state as supplementary information are displayed. Therefore, when the examination contents for each patient are developed and displayed on the execution result registration screen, for example, as shown in FIG. 3, an imaging menu for each patient and information on the patient's physical condition are displayed.

  The information on the patient's physical condition as incidental information may be included in the patient information in the examination order issued to the radiology department, or may be input in advance, or the radiology department that received the examination order. You may make it input with.

  After confirming the examination order for each patient, the engineer determines whether the examination should be performed simply for each patient in the order of the order, or whether the examination order for each patient should be reset. If it is determined that the inspections are simply performed in the order, the X-ray imaging is performed according to the order in which the orders are received and the imaging menu. However, if X-ray imaging is performed simply in accordance with the order received and the imaging menu, it is inappropriate for reasons such as the patient's movement being increased and the burden on the patient increased, or problems such as reduced examination efficiency occurred. If it is determined that it is, an instruction is issued to the RIS server 10 via the terminal 11 so that the order of X-ray imaging including rearrangement of examination order between patients is rearranged. Note that it may be automatically determined by software from the stage of determining whether to examine each patient simply in the order of the order or to reset the order of examination between patients.

  Now, one means for rearranging the order of examination contents including the exchange of examination order between patients is as follows.

  That is, first extract the patient's physical state from the incidental information, need assistance, consider symptoms, etc. according to the state set in advance in the medical facility and the priority table according to its degree, Change the order of patient imaging. Next, with respect to the imaging menu ordered by each patient, the imaging order in which the imaging order is set in advance as a standard based on this key is also used with respect to the imaging site and imaging position and direction at the medical facility. Based on the order conversion table, the order of X-ray imaging for each patient is rearranged.

  Here, it is further checked whether or not the X-ray imaging order of the patients before and after is appropriate for the patients whose imaging order is changed according to the priority table. That is, in relation to the last X-ray imaging in the previous patient and the first X-ray imaging in the next patient, X-ray imaging is performed again on the subsequent patient so as to enable more efficient X-ray imaging. Rearrange the order.

  Next, the flow of inspection after receiving such an inspection order will be described in more detail with reference to the flowchart shown in FIG.

  In FIG. 4, step 1 represents that an order list is displayed when the terminal 11 is activated, and an example of the order list is as shown in FIG. Step 2 represents a step of expanding and displaying the examination contents for each patient on the execution result registration screen. For example, as shown in FIG. 3, the imaging menu and the patient's body in which the examination contents for each patient are developed in order. Information about the status is displayed.

  Next, as step 3, it is determined whether such a test order of three patients should be simply performed for each patient in the order of the order, or whether the test order for each patient should be reset. . If re-setting is unnecessary (NO), that is, if the examination is simply performed in the order, the process proceeds to step 10, and X-ray imaging is performed for patients A, B, and C according to the order received and the imaging menu. .

  On the other hand, when it is determined in step 3 that the inspection order should be reset (YES), the process proceeds to step 4, and the terminal 11 refers to the priority order table set in advance in the RIS server 10 and follows it accordingly. Execute the rearrangement of examination order between patients. FIG. 5 shows this state, and FIG. 5A shows exactly the same contents as FIG. 3 in which the examination contents for each patient are expanded and displayed on the execution result registration screen, and FIG. Shows the result of performing the rearranged examination sequence between patients. That is, the priority table is set so that X-rays are preferentially taken for patients who need assistance or need attention to symptoms, so three patients A, B, C Because patient B's physical condition is the use of a stretcher, patient B is X-rayed first, and both patients A and C can walk alone and do not need special prioritization. The inspection order is rearranged as shooting is performed.

  Next, the process proceeds to step 5, and regarding the imaging menu ordered for each patient, the imaging order is set in advance as a standard in advance based on this key using any one of the imaging site, imaging position and direction at the medical facility as keys. The X-ray imaging order for each patient is rearranged based on the imaging order conversion table. This imaging order conversion table is stored in the RIS server 10. The result is, for example, as shown in FIG. In FIG. 6, FIG. 6 (a) shows exactly the same contents as FIG. 5 (b) showing the result of performing the rearrangement of examination order between patients, and FIG. 6 (b) shows the results for each patient. The result of rearranging the order of X-ray imaging is shown. That is, in the imaging order conversion table, if the imaging position is given priority among the imaging parts and the imaging positions, and the standing position is given priority among the imaging positions, the rearrangement is performed for patient B because only the supine position is acquired. For patient A, X-ray imaging is performed so that imaging of the upper abdomen, lower abdomen, and lower back is prioritized for patient A, and then the upper abdomen, lower abdomen, and lower back are acquired in the prone position. The order is rearranged. Further, for the patient C, the lower abdominal area imaging in the standing position is prioritized, and the X-ray imaging order is rearranged so that the lower abdominal area and the waist region are subsequently captured in the prone position.

  When the rearrangement of the X-ray imaging order for each patient is completed, the process proceeds to Step 6 to determine whether or not the X-ray imaging order of the patients before and after the patient is appropriate according to the priority table, that is, the previous patient. It is checked whether or not more efficient X-ray imaging is possible in the relationship between the last X-ray imaging and the first X-ray imaging of the next patient. Here, in consideration of, for example, the operation status of the X-ray imaging apparatus or the bed apparatus used for the examination, whether or not the last imaging position in the previous patient and the first imaging position of the patient who undergoes the examination after that are the same Shall be checked.

  As a result, if the last imaging position of the previous patient and the first imaging position of the patient to be examined after that are the same (YES), proceed to step 7 and create the result in step 5 as a new order list. If (NO), the X-ray imaging order is rearranged again so that the process proceeds to step 8 so that the first imaging posture is the same as the last imaging posture of the previous patient. However, at this time, the priority of the photographing position is changed to the second order.

  As can be seen from FIG. 6 (b), as a result of rearranging the order of X-ray imaging for each patient in step 5, the last X-ray imaging of patient B performing the examination first is to take the lumbar spine in the supine position. In the first X-ray imaging of the patient A who performs the second examination, the upper abdomen is imaged in a standing position. For this reason, in step 8, rearrangement is changed so that the patient A is in the supine position as the photographing position.

  The result is, for example, as shown in FIG. In FIG. 7, FIG. 7 (a) shows exactly the same contents as FIG. 6 (b) showing the result of rearranging the order of X-ray imaging for each patient, and FIG. The result of having changed the order of X-ray imaging so that the first X-ray imaging of this may be in a supine position is shown. At this time, not only the body position may be changed but also the imaging region may be adjusted. Therefore, in this embodiment, in FIG. 7 (b), since the end of the patient B is X-ray imaging of the lumbar spine, the first X-ray imaging of the patient A is the X-ray imaging of the lumbar spine. Then, the upper abdomen is taken in the prone position and the lower abdomen is taken in the prone position. Furthermore, as for what is image | photographed by standing position, it rearranges in order of a lower abdominal part standing position, an upper abdominal part standing position, and a waist standing position so that the imaging | photography site | part with the front may become the same.

  Subsequently, in step 9, it is checked whether all patients have been rearranged so that the last photographing position in the previous patient is the same as the first photographing position in the patient to be examined thereafter. For example, the process returns to step 8 and the order of X-ray imaging is rearranged in the same manner for the second and third patients. In the present embodiment, when comparing the positions of the last imaging in the second patient A and the first imaging in the third patient C, both are standing, and only the lower abdomen is captured in the standing position. The imaging sequence of patient C is not changed again. If all the patients have been completed, the process proceeds to Step 7, and a new order list as a result is created. The new order list is as shown in FIG.

  Therefore, after an order list indicating a new examination order is created in step 7, the engineer sequentially executes X-ray imaging of patients B, A, and C according to the new order list in step 10. Then, it is checked whether or not all the inspections ordered in Step 11 have been performed. If there is any inspection, the process returns to Step 10 to continue the inspection, and when it is confirmed that all the inspections have been completed. A series of operations is completed.

  As described above in detail, according to the present invention, the least burden is placed on the patient with respect to the number of patients for whom an examination order has been placed, the physical condition of each patient, the examination site and the imaging position and direction of each patient, and the like. In order to perform examinations efficiently, the order of imaging between patients has been changed and the order of imaging for each patient can also be reset, so the patient must be forced to change their position many times. The burden on the patient's body can be reduced. In addition, the number of times of changing the position of the bed can be reduced, the burden on the engineer can be reduced, and the inspection efficiency can be improved.

  In addition, this invention is not limited to the above-mentioned one Example, In the range which does not deviate from a summary, it can implement in a various aspect. For example, based on a predetermined correspondence table or program, a series of operations for resetting the order of inspection is made into a mode, and rearrangement of the photographing order is automatically performed by operation, or manually performed. be able to. That is, in the initial setting, the automatic rearrangement mode is turned on, and if you want to change the shooting order arbitrarily for some reason, or if you want to change the position because you want to take a picture for each part, The automatic rearrangement mode may be turned off to allow manual rearrangement of the photographing order.

  For example, for the patient A, when it is inevitably desired to continuously photograph only the lower abdomen, it is possible to rearrange the images manually by turning off the automatic rearrangement mode so that the photographing order becomes the order shown in FIG. That is, FIG. 8A is the same as the result of resetting the imaging order for the patient A shown in FIG. 6B, but in contrast, “(2) Standing on the lower abdomen” Is lowered to “(3) Lumbar Standing Position”, and “(5) Lower Abdominal Spine Position” is lifted above “(4) Upper Abdominal Spine Position”, as shown in FIG. , "(3) Lower abdomen standing" and "(4) Lower abdomen prone" can be taken continuously. As described above, after the photographing order is reset in the automatic rearrangement mode, the automatic rearrangement mode may be turned off so that the rearrangement of the photographing order can be manually performed.
