Hereinafter, a first embodiment of a method for measuring the amount of bleeding based on the amount of gauze and saline injected according to the present invention will be described in detail with reference to the accompanying drawings.

The first embodiment of the method for measuring the amount of bleeding based on the amount of gauze and saline injection is described with reference to the accompanying drawings, in which the weight is initially set by the controller after the drainage container is seated on the upper part of the main body (S10) , based on the number of gauze in the control unit, based on the gauze blood measurement step (S20) of measuring the patient's bleeding amount absorbed by the gauze during surgery, and the amount of saline injected in the control unit, the total bleeding amount of the patient after surgery It is configured to include a bleeding amount measurement step (S30) of measuring the.

First, in the initialization setting step (S10), after the drainage container 350 is seated on the upper portion of the base unit 110, the weight is initially set by the first control unit 600. More specifically, first, the blood loss meter 10 is to be placed in a position that can be seen best in the operator's field of vision in the operating room. The operator executes a dedicated application installed on the smart device 800 to connect with the first wireless communication unit 700 . In this case, the first wireless communication unit 700 allows the first control unit 600 and the smart device 800 to be linked in real time. Of course, the operator may connect the smart device 800 to the measurement unit 400 by wire. Before the operation starts, the operator places the drainage container 350 on the upper part of the base part 110 and then sets the weight to be initialized.

Next, in the gauze blood measurement step ( S20 ), based on the number of gauze in the first control unit 600 , the amount of bleeding of the patient absorbed by the gauze during surgery may be measured. More specifically, the gauze blood measurement step (S20) includes an article input step (S21), a weight measurement step (S22), a gauze blood calculation step (S23), and a gauze blood output step (S24).

In the product input step ( S21 ), information is inputted through the input unit 900 while the gauze and the gauze holder 200 used during surgery are mounted. More specifically, the operator before surgery inputs the number of the gauze and the gauze holder 200 to be used in the dedicated application. This is to ensure that the number of gauze that the medical staff intends to use is clearly displayed, so that the medical staff does not mistake the number of gauze that has been opened during the operation. At this time, the gauze can be classified according to the size, such as Small (small), Midium (medium), Large (large). For example, FIG. 14 is an example of a dedicated application installed in the smart device 800, and before the operation starts, the operator inputs the number of the gauze and the gauze holder 200 to be used during surgery in the TOTAL COUNT item. . In addition, the operator can input the weight of the gauze and the gauze holder 200 in the application.

Thereafter, the operator proceeds with the operation, fixing the gauze with the patient's blood on the gauze holder 200 during the operation, and the gauze holder 200 is hung on the gauze holder hook 320 . At this time, the operator uses the application's USED COUNT item whenever the gauze holder 200 is hung on the gauze holder hook 320 or the gauze is hung on the gauze holder 200 hung on the gauze holder hook 320. The number of the gauze and the gauze holder 200 used in the input is additionally entered. For example, when the operator does not mount the gauze holder 200 and does not input the number of the gauze holder 200 and the gauze used for the application, the blood weight output is maintained as it is.

In the weighing step (S22), the weight sensor 500 measures the total weight of the gauze, the gauze holder 200, the gauze holder hook 320, the drainage container 350, and the contents accommodated in the drainage container. measure More specifically, the weight sensor 500 includes the gauze, the gauze holder 200, the gauze holder hook 320, the drainage container 350, and the contents accommodated in the drainage container 350 with the patient's blood on it. The weight is sensed and transmitted to the first control unit 600 .

In the gauze blood calculation step ( S23 ), the amount of blood absorbed by the gauze is calculated from the total weight measured by the weight sensor 500 by the first control unit 600 . More specifically, the number of the gauze and the gauze holder 200 input in the application and the weight of the gauze and the gauze holder 200 are transmitted to the first control unit 600 . The first control unit 600 includes the gauze, the gauze holder 200, the gauze holder hook 320, the drainage container 350, and the drainage container on which the patient's blood detected by the weight sensor 500 is stained. Calculate the patient's bleeding amount absorbed by the gauze by subtracting the weight of the gauze, the gauze holder 200, the gauze holder hook 320, and the drainage container 350 from the weight of the contents accommodated in 350 . Of course, in the calculation process, the gauze and the gauze holder 200 are calculated with their own weight proportional to the number.

In the gauze blood output step (S24), the amount of blood absorbed by the gauze calculated by the first control unit 600 is displayed on the output unit. More specifically, the first control unit 600 transmits the calculated amount of bleeding of the patient absorbed by the gauze to the first wireless communication unit 700 and displays it on the output unit 1000 of the smart device 800 . let it be

Next, in the bleeding amount measurement step ( S30 ), the total bleeding amount of the patient is measured after the operation is finished, based on the input amount of saline in the first control unit 600 . More specifically, the bleeding amount measurement step (S30) includes a saline injection step (S31), a bleeding amount calculation step (S32), and a bleeding amount output step (S33).

In the saline input step (S31), while the used saline solution is discharged to the drainage container 350, the input amount of the saline solution is inputted through the input unit 900. More specifically, in order to measure the total amount of blood loss of a patient during surgery, it is preferable to measure not only the patient's blood absorbed by the gauze, but also the saline solution used during surgery and mixed with the patient's blood. In general, the drainage mixed with the patient's blood is contained in a drainage container provided separately. The operator pours the drainage contained in the drainage tube into the drainage container 350 after the operation is finished. At the same time, the operator can input the amount of saline in the application.

In the bleeding amount calculation step S32 , the patient's bleeding amount is calculated from the total weight measured by the weight sensor 500 by the first control unit 600 . More specifically, the input amount of the saline solution input in the application is transmitted to the first control unit (600). The first control unit 600 includes the gauze, the gauze holder 200, the gauze holder hook 320, the drainage container 350, and the drainage container on which the patient's blood detected by the weight sensor 500 is stained. The total bleeding amount of the patient by subtracting the weight of the gauze, the gauze holder 200, the gauze holder hook 320, the drainage container 350, and the amount of saline from the weight of the contents accommodated in 350 Calculate.

A method of calculating a patient's bleeding amount through saline is an example, assuming that the initial dose of the saline solution is 500ml, of which 200ml is used for the patient during surgery, the patient's blood is mixed with the drainage container by the operator It is poured into (350), and the remaining unused 300ml is also poured into the drainage container (350). At this time, since the drainage is mixed with the patient's blood, a volume greater than 200 ml is accommodated in the drainage container 350 . Therefore, if it is assumed that the total volume accommodated in the drainage container 350 is 550 ml, if 500 ml of the initial saline solution is subtracted, the patient's bleeding amount contained in the saline solution can be derived as 50 ml.

In the bleeding amount output step (S33), the patient's bleeding amount calculated by the first control unit 600 is displayed on the output unit. More specifically, the first control unit 600 transmits the calculated patient's bleeding amount to the first wireless communication unit 700 and displays it on the output unit 1000 of the smart device 800 . In addition, the patient's bleeding amount information calculated by the first control unit 600 may be automatically stored after surgery. Accordingly, the operator may extract the patient's bleeding amount information through the main body connection unit 162 .

In addition, as an example, the blood loss meter 10 may also calculate the total amount of bleeding of the patient in the second control unit 610 . For example, the first control unit 600 may transmit the total weight detected by the weight sensor 500 to the first wireless communication unit 700 . The first wireless communication unit 700 may transmit the weight to the second wireless communication unit 710 . Accordingly, the second control unit 610 may calculate the total bleeding amount of the patient in the same manner as the first control unit 600 .

Also, the second control unit 610 may calculate the total amount of bleeding of the patient and transmit a signal to the output unit 1000 . Accordingly, the output unit 1000 may display the total amount of bleeding of the patient calculated by the second control unit 610 . In addition, the patient's total bleeding amount information calculated by the second controller 610 may be automatically transmitted to the first controller after surgery. Accordingly, the operator may extract the patient's bleeding amount information through the main body connection unit 162 .

Also, as an example, the bleeding amount meter 10 may input the amount of blood discharged from the drainage container 350 through the input unit 900 and display it on the output unit 1000 . More specifically, the blood contained in the drainage container 350 may be purified and administered back to the patient's body. For example, a patient's blood and a mixture of the patient's blood are accommodated in the drainage container 350 , and the operator discharges or moves 500ml of the patient's blood to another location in order to administer it to the patient's body. In this case, the operator may input 500ml into the input unit 900 , and the inputted patient's blood may be displayed through the output unit 1000 . In this case, the time information is displayed on the output unit 1000 for reference, so that the operator does not mistake the patient's blood administration time.

Hereinafter, a second embodiment of the method for measuring the amount of bleeding based on the amount of gauze and saline according to the present invention will be described in detail with reference to the accompanying drawings.

The second embodiment of the method for measuring the amount of bleeding based on the amount of gauze and saline injection is described with reference to the accompanying drawings, in which the weight is initially set by the controller after the drainage container is seated on the upper part of the main body (S10) and a total bleeding amount measurement step (S40) of measuring the patient's total bleeding amount in real time during surgery based on the number of gauze and the amount of saline in the control unit.

First, since the initialization setting step S10 is the same as that of the first embodiment, the description of the first embodiment is used.

Next, in the total bleeding amount measurement step ( S40 ), based on the number of gauze and the input amount of saline in the first control unit 600 , the total bleeding amount of the patient can be measured in real time during surgery. More specifically, the total bleeding amount measurement step (S40) includes a product input step (S41), a weight measurement step (S42), a saline information input step (S43), a blood weight calculation step (S44), and a blood weight output step (S45) includes

Since the product input step (S41) and the weight measurement step (S42) are the same as those of the first embodiment, the description of the first embodiment is used.

In the saline information input step (S43), when saline is used to calculate the patient's bleeding amount, the saline solution input amount is input through the input unit 900 . More specifically, in the case of calculating the patient's bleeding amount through the saline solution used during surgery, the operator connects the inhaler to which the saline solution is sucked and the pipe 351 . Accordingly, the saline is introduced into the drainage container 350 through the pipe 351 . Of course, when saline is not used, only the amount of bleeding of the patient absorbed by the gauze is calculated as in the first embodiment. When the operation continues and the saline solution is all sucked into the drainage container 350 , the operator inputs an input amount of the saline solution to the input unit 900 . If the saline solution is not all sucked into the drainage container 350, the process returns to the weighing step (S42) again, and the weight is continuously measured.

In addition, in the blood weight calculation step ( S44 ), the total amount of blood loss of the patient is calculated from the total weight measured by the weight sensor 500 by the first control unit 600 . More specifically, the number of gauze and the gauze holder 200 input in the application, the weight of the gauze and the gauze holder 200, and the input amount of saline are transmitted to the first control unit 600 . The first control unit 600 includes the gauze, the gauze holder 200, the gauze holder hook 320, the drainage container 350, and the drainage container on which the patient's blood detected by the weight sensor 500 is stained. The gauze, the gauze holder 200, the gauze holder hanger 320, the self weight of the drainage container 350, and the amount of saline absorbed by the gauze are subtracted from the weight of the contents accommodated in 350. Calculate the amount of bleeding and the amount of bleeding in the patient that was mixed with drainage. Of course, in the calculation process, the gauze and the gauze holder 200 are calculated with their own weight proportional to the number.

In addition, in the blood weight output step ( S45 ), the patient's bleeding amount absorbed by the gauze calculated by the first control unit 600 and the patient's bleeding amount mixed with the drainage are displayed on the output unit. More specifically, the first control unit 600 transmits the calculated total bleeding amount of the patient to the first wireless communication unit 700 and displays it on the output unit 1000 of the smart device 800 .

With the above-described method, the blood loss meter 10 may calculate the total amount of bleeding of the patient in real time during surgery.

Hereinafter, a method for measuring the amount of bleeding based on the input amount of gauze and saline and a third embodiment of a measuring instrument using the same will be described.
