Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" This invention is applicable to
The present invention relates to a bleeding m measuring device that can easily and quickly measure i (corresponding to bleeding m) and the number of gauze used.

``Prior art'' Conventionally, the number of pieces of gauze used in surgery has been confirmed by placing one piece of gauze into each compartment of a shallow container divided into 18 small compartments, and then counting the number of pieces of gauze. The used gauze was hung one by one on a large number of hooks, and the numbers were counted.

In addition, to measure the amount of blood attached to the used gauze, measure the weight of the used gauze whose number has been confirmed as described above on a stand, and then use the measured weight to measure the amount of unused gauze that has been measured in advance. This was done by subtracting the weight (corresponding to the number of sheets used).

"Problems to be solved by the invention" In the conventional method of measuring the number of gauze sheets and the amount of bleeding,
First, there is the problem that measurement takes time and increases the burden on nurses who take measurements, making it difficult for nurses to concentrate on their primary nursing duties. In addition, because measurement takes time, water evaporates during that time, and the full scale of the measuring instrument is 1 kg, and the minimum scale is 2 g. The problem is that the measurement error is too large and the measurement results are unreliable.

This invention was made in view of the above circumstances, and its purpose is to measure the number of used gauze sheets and the amount of blood (bleeding m) attached to these gauze sheets by simply inserting each used gauze sheet one by one. An object of the present invention is to provide a blood loss measurement device that can measure blood loss easily, quickly, and accurately.

"Means for Solving the Problems" The blood loss measuring device according to the present invention includes: a gauze input section formed in a funnel shape and having a passing object sensor at the bottom thereof; and a gauze input section provided below the gauze input section. a weighing section; a first setting section for storing and displaying the number of gauze sheets before use; a second setting section for storing and displaying weight data of unused gauze l; a used number measuring unit that stores and displays accumulated data; and a first unit that calculates and displays the remaining number of unused gauze by subtracting the number measured in the used number measuring unit from the initial set number of the first setting unit. a calculation section, and a section that calculates and displays the total output group from the weight of gauze before use stored in the second setting section, the number of sheets measured by the number of sheets used measuring section, and the weight measured by the weighing section. This device has two calculation units.

"Function" According to the above configuration, the number of pieces of gauze prepared before the start of surgery and the weight of one piece of gauze are set in the first setting section and the second setting section, respectively.
All you have to do is input the gauze into the setting section of the device, and then as the surgery progresses, you can input the used gauze one by one into the gauze input section of the device, and you can check the exact gauze used over time in real time. The number of sheets, the number of remaining unused gauze sheets, and bleeding M are automatically measured and displayed.

It will be done. Therefore, by using this blood loss measurement device, the burden on nurses who perform blood measurement is significantly reduced, allowing them to concentrate on their primary nursing duties.

Hereinafter, this invention will be explained in more detail with reference to Examples.

Embodiment FIGS. 1, 2, and 3 are for explaining an embodiment of the present invention, and the reference numeral 1 in FIG. I indicates the main body of the apparatus. A funnel-shaped gauze input portion 2 is provided at the upper part of the device main body I. Passage object sensors 3.3 are attached to both sides of the lower part of the gauze input section 2. Further, a scale (weighing section) 4 is installed in the lower part of the device main body 1 below the gauze input section 2. Further, on the front part of the main body of the device, there is a first setting section 5 that inputs the number of sheets of gauze before use using a setting button 5a, stores it, and displays it on the display section 5b, and a first setting section 5 that displays the number of sheets of gauze before use. A second setting section 6 is provided for inputting weight data using a setting button 6a, storing it, and displaying it on a display section 6b.

As shown in FIG. 2, the optical signal from the passing object sensor 3.3 counts by 1 when it is blocked, and sends the counted number to the total count accumulating section 7 and the arbitrary accumulating section 8, respectively. The counts in the total count accumulating section 7 and the arbitrary accumulating section 8 are stored in the first storage section 9 and the second storage section 10, respectively. The count number of the first storage section 9 is displayed on the first display section 11, and the count number of the second storage section IO is displayed on the second display section 13 via the atmosphere reset section 12. It has become. The zero reset section 12 can arbitrarily erase the counts in the arbitrary count accumulator 8 and the second storage section IO to make them zero counts.

On the other hand, the α section (third storage section) written by the first setting section 5
Record of 5c↑・3 pieces lost (number of pieces of gauze prepared on the surgical surface)
is manually input to the subtraction unit 14, the total count number (the number of used gauze sheets) stored in the first storage unit 9 is read into the subtraction unit 14, the subtraction is executed, and the balance calculated thereby is read. The number of remaining sheets of gauze to be used is displayed on the third display section 15.

In the above configuration, the total count accumulation section 7, the arbitrary accumulation section 8, the first storage section 9, the second storage section 10, the first display section 11, the zero reset section 12, and the second display section 13 are , constitutes a usage number measuring section 16, and the subtraction section 14 and the third display section 15 constitute a first calculation section 17.

Further, the integrated data of the weight of gauze used by the scale 4 is manually inputted to the total sales amount calculation section 18.

On the other hand, this total sales amount calculating section 18 stores the recorded weight (weight of one unused gauze) in the storage section (fourth recording section) 6c of the second setting section 6 and the weight of one unused gauze sheet in the first storage section 9. The integrated value (total weight of the gauze used) is read with the measurement data (number of sheets of gauze used), and in this total bleeding flea calculation unit 18, the blood m (m) attached to the gauze used is read. The total exposed surface Pf1) is calculated. The total blood loss book calculated in this way is the total blood loss storage unit (fifth storage unit) 1
9 is stored.

When this total blood loss report is displayed on the fifth display section 20, it is sent to the subtraction section 21. When the data that has passed through the subtraction section 21 is canceled by the reset section 22, the data (bleeding amount) at the time of the reset is recorded in the sixth storage section 23, and then supplied from the fifth storage section 19. This data is subtracted from the integrated blood volume data that has been calculated, so that it is possible to know the bleeding m after the reset. The amount of bleeding b′ calculated in this way or the bleeding amount M after resetting is stored in the seventh storage unit 24,
It is supplied to the calculation unit 25. This calculating section 25 includes the second
The data (used gauze and number of pieces after reset) in the storage unit 1O is read, and the bleeding m per used piece of gauze is calculated from these data and displayed on the sixth display unit 26. Here, regarding the blood loss measurement, the stored data read in the measurement of the number of gauze sheets is the total output amount calculation unit 18.
Data in the first storage unit 9 (number of sheets of gauze used)
and the data (the number of used gauze sheets after reset) in the second storage unit 10 in the calculation unit 25.

In addition, in the said structure, the total volume calculation part 18, the total blood loss storage part (fifth storage part) 19, the 5th display part 20,
Subtraction section 21, reset section 22, sixth storage section 23, seventh
The storage unit 24, the calculation unit 25 and the sixth display unit 26 are
It constitutes the second calculation section 27.

Therefore, the number of used gauze sheets and the remaining number of unused gauze sheets can be known by the total bleeding measurement device having the above configuration as follows. First, when a signal from the sensor 3.3 is detected, it is counted by the total count accumulating unit 7 and the arbitrary count accumulating unit 8, and the counted numbers are respectively stored in the first memory unit 9 and the second memory unit 1G. . The total number of used gauze is displayed as is on the first display section 11. The count of gauze in the counting unit 8 is cleared to zero if it is reset, and if it is not reset, it is accumulated as it is and the number of gauze pieces is displayed on the second display unit 13. The number of gauze pieces prepared and set in advance is entered into the third storage section 5c, immediately displayed on the display section 5b, and subtracted from the count number in the first storage section 9 read in the subtraction section 14. The number of processed and unused gauze remaining is displayed on the third display section 15.

On the other hand, the amount of bleeding is known as follows. The weight of one piece of unused gauze is put into the storage section 6c in advance, used gauze is put in, and when the weight is applied to the scale 4, a signal is detected. The detected signal is subtracted by the total sales amount calculating section 18, and the calculated total amount of blood is stored in the fifth storage section 19 and displayed on the fifth display section 20. At the same time, the bleeding amount of reset nη is subtracted from the total cumulative blood loss part 2
The subtraction process is performed in the summer, and the division process is performed between the number of pieces of gauze used before reset, which is read in the calculation unit 25 via the seventh storage unit 24, and the number of pieces of gauze before reset is calculated.
The amount of bleeding per sheet is calculated and displayed on the sixth display section 26. Note that when the reset is performed, the data (bleeding amount) of the subtraction unit 21 at the time of the reset is stored as new data in the sixth storage unit 23, and the calculated value in the subtraction unit 21 is set to zero and stored in the seventh storage unit 23. section 24, and enters the sixth display section 2.
Set the display of 6 to zero.

In the above embodiment, the number-of-sheets-in-use measuring section 16 is divided into a total count accumulating section 7, an optional accumulating section 8, a first storage section 9, a second storage section 10, a first display section 11. Zero reset section 12
and a second display section (3), but since the minimum practical requirement is the number of sheets of gauze to be used, the optional integration section 8, second storage section IO, and zero reset section 12 are omitted. There may be cases where you do so. Similarly, the second arithmetic unit 27 is connected to the total blood loss set calculation unit 18 and the total blood loss storage unit (fifth
(storage unit) 19, a fifth display unit 20, a subtraction unit 21, a reset unit 22, a sixth storage unit 23, a seventh storage unit 24, a calculation unit 25, and a sixth display $26, Since the minimum requirement for practical use is the cumulative total hemorrhage control, the steps from the subtraction section 21 to the sixth display section 26 may be omitted.

"Effects of the Invention" As explained above, according to the blood loss measuring device according to the present invention, the number of gauze sheets and the weight of one gauze sheet are set at the first setting section and the second setting section, respectively, at the start of surgery iη. All you have to do is input it into the settings section of the device, and then as the surgery progresses, you can feed the gauze used one by one into the device's gauze input section, and over time RealTie 11 will provide accurate information. The number of used gauze sheets, the number of unused gauze sheets remaining, and the amount of bleeding are automatically measured and displayed. Therefore, by using this blood loss ■1 measurement device, the burden on nurses who perform blood measurement can be greatly reduced.
