Abstract

The utility model provides a device for differential leukocyte count. A monolithic computer, a light touch keyboard and an LED digital code tube are matched with a specific program to carry out work, and six kinds of cell keystrokes: a sublobe keystroke, a rod-shaped keystroke, a lymph keystroke, a monocaryon keystroke, an acidophil keystroke, a basophil keystroke, etc., and two function keys; an 'other' and an 'M' are arranged on the light touch keyboard. The LED digital code tube has six sets, and every set has two bits which are respectively corresponding to more than six kinds of cell keys and the function key 'other' is a logic switch. After the utility model is pressed, six kinds of cell keys can be renamed, and six sets of corresponding LED digital code tubes display the count situation of renamed cell keys. 'M' is enabled to press the sublobe key and the lymph key once to realize the logic switch of count plus 1 or count plus 5.

Description

Electronic type sorting counter for leucocyte

The utility model relates to a kind of improved differential white blood cell counter, particularly can realize 12 kinds of cytological classification countings and device shown under the situation of six kinds of cell buttons and six groups of (two every group) LED charactrons.

Existing simple and easy geared machine formula Arneth's count device is by nine kinds of cell buttons, gearing, and nine groups of display parts are formed.After pressing a certain cell key, corresponding display part adds 1.Nine kinds of cell buttons of existing electronic type Arneth's count device operated by rotary motion, one group of charactron show, press a certain cell key after, charactron shows each cell accumulative total.The Arneth's count device that sell in market is exactly above two kinds of forms.Mechanical type Arneth's count device exists the stroke of button big, and hot-tempered sound is big, Heavy Weight, and mechanical wear is very fragile, and the kind of cytological classification is few, defective such as can only count one by one.Electronic type Arneth's count device exists the kind of cytological classification few, can only count one by one, particularly show because of one group of charactron only is set, so when reading classification results defective such as inconvenience.

Task of the present utility model is that a kind of improved differential white blood cell counter will be provided, it is in light weight, there is not hot-tempered sound, key stroke is short, can be to each 5 countings of common cell, and can on six kinds of cell keys, carry out differential count easily, and on six groups of charactrons, directly read the classification results of 12 kinds of cells 12 kinds of cells.

Task of the present utility model is finished in the following manner:

Have in plastics inner-box device one-chip computer inside 2KEPROM 8749 for the motherboard of CPU with touch keyboard, be equipped with specific program work.Six groups (two every group) seven sections LED charactrons are arranged, corresponding the i.e. six kinds of cell keys such as ' leaflet ', ' shaft-like ', ' lymph ', ' monokaryon ', ' having a liking for acid ', ' having a liking for alkali ' of six kinds of cell keys being provided with on the keyboard that touch on motherboard.Touch keyboard and be provided with ' other ' key, this key is a logic switch, resets during start.Pressing after it can be to six kinds of cell keys from rebaptism, and six groups of corresponding LED charactrons show from the counting situation of the cell key of rebaptism.Be provided with " M " key touching on the keyboard, ' M ' key resets when being logic switch, start, whenever presses once the value that ' leaflet ' key or ' lymph ' key show its corresponding LED charactron and adds 1.After pressing ' M ' key, whenever press once ' leaflet ' or ' lymph ' key and make the value of its corresponding LED charactron demonstration add 5.

Below in conjunction with accompanying drawing utility model is described in further detail.

Fig. 1 is that each key name and position and LED charactron position are by the front view of arranging for concrete the comprising of the utility model.

Fig. 2 is the complete section left view of main diagrammatic sketch.

Fig. 3 is the electrical schematic diagram of utility model.

With reference to Fig. 1, on plastic housing (1), have six groups of transparency windows, be marked with six kinds of cell titles such as ' leaflet ', ' shaft-like ', ' lymph ', ' monokaryon ', ' having a liking for acid ', ' having a liking for alkali ' respectively as shown in the figure.Be provided with ' total clear ', ' other ', ' M ' touching on the keyboard (4) respectively as shown in the figure and wait six kinds of cell buttons such as three function buttons and ' leaflet ', ' shaft-like ', ' lymph ', ' monokaryon ', ' having a liking for acid ', ' having a liking for alkali '.

With reference to Fig. 2 and Fig. 1, motherboard (2) and touch keyboard (4) and be installed in the plastic housing (1) has six groups of LED charactrons (3) on the motherboard (2), and these six groups of LED charactrons (two every group) align with six groups of transparency windows on the plastic housing (1).

With reference to Fig. 3, in the inner 2KEPROM of single-chip microcomputer 8749CPU specific program is arranged, program listing is attached, and eight I/O mouths of BUS mouth and 7,4LS,244 40 Ω * the 8 and 12 common cathode LED charactron that linked links, and drives as section.It is the position driving of 12 LED charactrons that low four I/O mouths and 7407 of eight I/O mouths of P2 and P1 mouth link.(P14, P15, P16, the P17) of P1 mouth is for reading the train value mouth that touches keyboard.

Single-chip microcomputer 8749CPU internal RAM is allocated as follows: the number of times of pressing of 0-5 key is stored in the 20H-25H unit.Wherein the 0-5 key touches ' leaflet ', ' shaft-like ', ' lymph ', ' monokaryon ', ' having a liking for acid ' in the keyboard (4) six kinds of cell buttons such as ' have a liking for alkali ' respectively in the corresponding diagram 1.6,7 key correspondences ' other ', ' M ' two keys.Can be for realizing that ' other ' key becomes from six kinds of cell keys of rebaptism, and, write down the situation of pressing of ' other ' key here with a unit among the RAM (usefulness is the 26H unit) with the logic switch that its value record gets off.After resetting, the 26H unit is complete 0.After pressing once this key, make 26H that the unit adds 1,26H unit lowest order is 1.After pressing this key again, this unit adds 1 again, and the 26H unit is minimum to be 0.When 26H unit lowest order was 0, execution can be stored in subroutine in the 20H-25H unit to the number of times of pressing of 0-7 key.When 26 unit lowest orders are 1 when cell key (named one group new), execution can be pressed number of times to the 0-7 key and is stored in subroutine in the 28H-2DH unit.When 26H unit lowest order is 0, after the binary-coded decimal conversion, send display buffer 2EH-39H from the peek of 20H-25H unit.When 26H unit lowest order is 1, after the binary-coded decimal conversion, send 2EH-39H unit, display buffer from the peek of 28H-2DH unit.After realizing that ' M ' key is become whenever and press that ' M ' key once, press once ' leaflet ' key or ' lymph ' bond energy again and make 20H unit or 22H unit add the logic switch of 5 computing.The situation of pressing with record ' M ' key in a unit (usefulness is the 27H unit here) among the RAM.The 27H unit is complete 0 after resetting, make this unit add 1 after pressing once, making 27H unit lowest order is 1, still make this unit add 1 after pressing twice, making 27H unit lowest order is 0, when 27H unit lowest order is 0, then carry out the 0-7 key is whenever pressed once can both add 1 subroutine, when 27H unit lowest order is 1, then carry out making 0,2 keys ' leaflet ', ' lymph ' key whenever press 1 energy to add 5 subroutine at its corresponding unit in its corresponding stored unit.
