In an embodiment of the present utility model, the opening on the cover plate is done the area of tapered, suitable for reading area greater than end opening, and the area of end opening is less than or equal to interior bucket cross-sectional area, enter interior bucket thereby be convenient to gauze.
In another embodiment of the present utility model, make a cone boss that stretches out downwards at the middle part of cover plate, boss puts in downwards in the interior bucket, its top ends near the photoelectric detection system mounting hole top, the said opening that supplies the input gauze to use is opened in the boss middle part, opening is taper, and last open area is greater than following open area.Be beneficial to gauze and enter interior bucket.Because being taper and its top, boss is positioned near the photoelectric detection system placed hole top, so, can prevent that the watery blood on the gauze is coated with the interference that the photoelectricity hole also can prevent external light source, avoid miscount.
In another embodiment of the present utility model, this counting machine also further comprises a light shield, and this light shield is suitable for injecting in the central opening of lid, and it is an inversed conical drum, its upper end of body has the flanging that is fit to ride on the cover plate, and the lower end extends near the photoelectric detection system mounting hole top.The setting of light shield not only had been beneficial to gauze and has entered interior bucket, but also can prevent that watery blood on the gauze is coated with and annotate the photoelectricity hole, also can prevent the interference of external light source.
The used photoelectric detection system of the utility model is infraluminescence triode and phototriode preferably, infraluminescence triode and phototriode use in pairs, be in 180 ° of angles, the logarithm of use is decided on the size of interior bucket, is not more than gauze with the space between the light path and is advisable.Use severally to infraluminescence triode and phototriode, then at circuit part several photoelectric switching circuits are just arranged, have interlocked relationship between these photoelectric switching circuits, as long as one the road detect signal, other several roads are just inoperative, in order to avoid repeat count.
Medical operation gauze counting machine of the present utility model also can be provided with power supply reset switch and counting locking switch on control panel.
The xsect of casing, cover plate and interior bucket can be square, also can be circular, and the shape of cover plate upper shed is preferably consistent with interior bucket.
Medical operation gauze counting machine of the present utility model is simple in structure, and good looking appearance is easy to use, safety.Circuitry part reliable working performance, counting accurately is adapted at promoting the use of in the medical operating.
Explain the utility model in detail below in conjunction with drawings and Examples.
Fig. 1 is the skeleton view of medical operation gauze counting machine of the present utility model;
Fig. 2 is the longitudinal diagram of counting machine shown in Figure 1;
Fig. 3 and Fig. 4 are two kinds of forms of implementation in addition of medical operation gauze counting machine of the present utility model;
Fig. 5 is the circuit diagram of medical operation gauze counting machine of the present utility model.
As depicted in figs. 1 and 2, six photoelectric detection systems, wiring board (not shown), control panel 6 and display 7 that medical operation gauze counting machine of the present utility model has a casing 1, cover plate 2, interior bucket 3, is made up of infraluminescence triode 4 and phototriode 5, the middle part of cover plate 2 has a tapered opening, in order to throw in gauze, the last open area of this opening is greater than following open area, and end opening equals the xsect of interior bucket.
Be distributed with 12 apertures on the top bucket wall of interior bucket 3, in order to infraluminescence triode 4 and phototriode 5 to be installed, infraluminescence triode 4 and phototriode 5 use in pairs, and every pair becomes 180 ° of angles, and the size of its mounting hole is suitable, so that contraposition.
Wiring board and control panel 6 are installed on the casing 1, and charactron display 7, power supply reset switch 8 and counting locking switch 9 are housed on control panel 6.
Circuit part comprises power circuit, has six photoelectric switching circuits of interlocked relationship, pulse shaping amplification circuit and counting display circuit (see figure 5).In six photoelectric switching circuits, as long as one the road detect signal, other five the tunnel just no longer works, in order to avoid repeat count.This counting machine adopts delay circuit, detect can postpone 450 milliseconds behind the signal after counting again.This counting machine also is provided with power supply reset switch 8, presses this switch, and display 7 recovers zero-bit.This machine also is provided with counting locking switch 9, presses this switch, then no matter bucket 3 what thing will not be counted in knocking down.
The circuit of circuit part is made printed-wiring board (PWB), and main components and parts are selected integrated circuit block for use.
Fig. 3 is another embodiment of the present utility model, and in this embodiment, except the gauze porch structure of cover plate 2 changed slightly, other structure and circuit part were identical with previous embodiment's.In this embodiment, there is a cone boss at the middle part of cover plate 2, and this boss puts in downwards in the interior bucket 3.The boss top ends near the mounting hole top of infraluminescence triode 4 and phototriode 5, opens in the boss middle part for the opening that the input gauze is used, and this opening is a back taper, and is promptly suitable for reading greater than end opening, and purpose is to be convenient to gauze to enter interior bucket.Because the boss top is positioned near infraluminescence triode 4 and phototriode 5 tops, and boss is back taper, so, both can prevent that the watery blood on the gauze was coated with the photoelectricity hole, can block of the interference of meal circle light source again to phototriode 5, avoid miscount.
Fig. 4 is the 3rd embodiment of the present utility model, and in this embodiment, except the central opening place at cover plate 2 injects the light shield 10, other structure and circuit part are identical with first embodiment's.This light shield 10 is the back taper cylindrical shell, i.e. the area of its upper shed is greater than the under shed area, and its upper end has the flanging 11 that is fit to ride on the cover plate 2, and the lower end puts in the interior bucket 3, and ends near infraluminescence triode 4 and phototriode 5 tops.The setting of light shield, purpose also are in order to prevent that the watery blood on the gauze is coated with the photoelectricity hole, and block the interference of external light source to phototriode 5, prevent miscount.
Medical operation gauze counting machine operating position of the present utility model is described below:
In the time need throwing away with the gauze of crossing, bucket 3 in the opening from the cover plate 2 is thrown into one by one with gauze is thrown away the action of gauze and must be finished in half second, causes repeat count in the bucket in order to avoid drop of blood is fallen into.When bucket 3 was by infraluminescence triode 4 and phototriode 5 in gauze enters, gauze moment sheltered from light path, opto-electronic conversion, and circuit is connected, and makes it become an electric impulse signal.There is the circuit storage in this pulse signal by counter lock after amplifying through shaping, and then decoding shows, and can obtain a numeral like this.Every shading once, circuit is connected once, counting shows once, the continuous like this gauze of checking treats that operation finishes, and shows how many numbers on the register, in the bucket how many piece gauzes is arranged promptly, equates with gauze number before the art, is gauze with complete.If number does not wait, then should in patient's abdomen He on the aseptic platform, look for, show that as if residue gauze number and counter on the aseptic platform number sum equals the preceding gauze number of art, can close abdomen this moment.
