Description

Measuring instrument of blood loss using gauze}

The present invention relates to a hemorrhage meter using gauze, and more particularly, to a blood loss meter using gauze so that the blood volume of a patient can be calculated by measuring the weight of blood on the gauze used during surgery.

Although many tools are used in the process of preparing a patient for surgery, of them, blood or body fluids that are essential in the surgical process must be removed frequently, so surgical gauze is an essential tool.

Although surgical gauze must be removed from the patient's body, it is often left in the patient's body due to the operator's mistake. If the gauze is left in the patient's body as described above, an abnormality may occur in the patient's health, and eventually the patient may need to undergo reoperation.

In addition, the gauze used during surgery is counted one by one by the operator in the operating room, and there is a possibility of losing the gauze in the process. There is a problem in that it is not possible to accurately determine the amount of bleeding during the process.

Patent Document 1 relates to a gauze counter bag, and more particularly, a gauze count bag capable of measuring the amount of blood lost during surgery while counting gauze for surgery used for absorption of blood and other body fluids generated during surgery is about

The gauze holder bag according to the above invention has the advantage of being able to easily calculate the gauze used in the surgical procedure, but has the disadvantage that it has to be calculated one by one like the conventional problems.

In addition, the operator allows the user to input the weight of the gauze holder 200, the gauze and other articles in the application.

Next, the operator proceeds with the operation, and fixes 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 holder 200 and the gauze 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. The number of the gauze holder 200 and the gauze and their own weight input in the application are transmitted to the first control unit 600 . The first control unit 600 is the gauze, gauze holder ( 200) and a method of subtracting the weight of the gauze holder holder 300 to derive the patient's bleeding amount absorbed by the gauze. The first control unit 600 transmits the calculated value back to the smart device 800 so that the patient's bleeding amount can be displayed. Accordingly, the bleeding amount meter 10 can calculate the amount of bleeding from the gauze soaked with the patient's blood through the same process as described above.

In addition, the bleeding amount meter 10 may calculate the amount of bleeding from the gauze stained with the patient's blood even in the second control unit 610 . For example, the first control unit 600 transmits the weight of the gauze, the gauze holder 200 and the gauze holder holder 300 detected by the weight sensor 500 to the first wireless communication unit 700 . can The first wireless communication unit 700 may transmit the weight to the second wireless communication unit 710 . Accordingly, the second control unit 610 transmits the weight of the blood-stained gauze, the gauze holder 200 and the gauze holder holder 300 detected by the weight sensor 500 from the input unit 900 . By subtracting the weight of the received gauze, the gauze holder 200, and the gauze holder holder 300, the amount of bleeding of the patient absorbed by the gauze can be calculated. That is, the smart device 800 receives the weight information of the blood-stained gauze, the gauze holder 200 and the gauze holder holder 300 from the measurement unit 400 in real time, and can calculate the patient's bleeding amount. there will be The second control unit 610 may calculate the patient's bleeding amount and transmit a signal to the output unit 1000, which will be described later. The output unit 1000 may display the patient's bleeding amount calculated by the second control unit 610 . Also, the patient's 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 .
