いる。FIG. 2 is a block diagram showing the outline of the use management device for the surgical gauze 1. In the figure, 4 is a detection coil,
Reference numerals 5 and 6 denote an oscillating unit and a drive unit that excite the detection coil 4, a detection unit 7 that detects a change in electromotive voltage of the detection coil 4, and a wave-shaping unit 8 thereof. The detection coil 4 is shown in FIG.
As also shown, the used surgical gauze 1 is horizontally arranged so that it can pass through the ring. When the surgical gauze 1 passes through the detection coil 4, the induced electromotive force of the detection coil 4 changes due to the approach and separation of the magnetic body 2.
The signal is converted into a pulse signal by the wave shaping section 8 and the number of pulses is counted by the counter section 9. Here, the detection coil 4 is shown in FIG.
As shown in FIG. 5, a plurality of electromagnetic coils are arranged vertically with a little space between them, and each detection coil 4, the oscillation unit 5, the drive 6, the detection unit 7, the wave shaping unit 8 and the like. Then, these are connected to the erroneous counting prevention circuit 10, and the erroneous counting prevention circuit 10 discriminates whether the count signals obtained from the respective electromagnetic sensors are coincident with each other or not. The number of pieces is displayed on the display unit 11, and if they do not match, an error is displayed. In addition,
Reference numeral 12 denotes an inclined baffle plate provided inside the detection coil 4 so that when the used surgical gauze 1 is put into the baffle plate 12, it hits the baffle plate 12 so that the gauze plate 12 falls while swinging slightly. Even if a plurality of surgical gauze 1 is in a lump shape, the plurality of detection coils 4 fall by changing the postures by this, so that the magnetic bodies 2 in the lump are surely pulsed by the number corresponding to the number. It is detected as a signal.

出す操作部である。Reference numeral 13 is a weight scale provided below the detection coil 4 for measuring the weight of the used surgical gauze 1 inserted in the detection coil 4. The data measured by the weight scale 13 is input to the calculation unit 14, and the calculation unit 14 calculates the total weight of the surgical gauze 1 after use measured by the weight scale 13 from the total weight of the surgical gauze 1 before use. By subtracting the weight, the amount of blood adhering to the surgical gauze 1 is calculated, and the value is displayed on the liquid crystal type display unit 15 for displaying the amount of bleeding. Reference numeral 16 is an operation unit for issuing a command such as reset to the calculation unit 14.

うになる。The surgical gauze 17 shown in FIG. 4 is obtained by weaving a rubber thread 19 made by mixing a certain amount (33 mm 3 ) of fine powder of ferrite into the magnetic material 18 together with other cotton threads 3. The number of sheets of the gauze 17 for use can be easily detected by detecting the magnetic substance 18 by the detection coil 4.

もできる。In the above-mentioned embodiment, an example in which a ferromagnetic ferrite is used for the magnetic body 2 is possible, but other metal materials can be used as long as the number can be detected by an electromagnetic sensor. Further, by pre-magnetizing the metal material, it becomes possible to cause electromagnetic induction in the coil with higher sensitivity. As shown in the embodiment, the operating coil gauze 1 or 17 does not necessarily have to pass through the detecting coil 4, and the detecting coil 4 may be stationary in the detecting coil 4. It is also possible to make it possible to accurately detect the number by changing the points.
