Description

The breast abdomen is alternately pushed device for resuscitating heart and pulmones
This utility model relates to a kind of breast abdomen that rescues when being used for hospital clinical to heart beating, respiratory arrest and alternately pushes device for resuscitating heart and pulmones.
Although the device for resuscitating heart and pulmones that at present domestic and international its structure, performance, effect have nothing in common with each other arises at the historic moment, push, breathe to regard to the device for resuscitating heart and pulmones of one with regard to collection, be the breast cardio-pulmonary resuscitation technology of pressing, and be the energy mostly with high pressure oxygen, have one or two gas bomb, after being full of gas, once only can use continuously about half an hour, can not satisfy the needs of long-time recovery.
The purpose of this utility model is for a kind of raising cerebral blood flow and myocardial blood flow are provided, prevent that stomach flatulence problem appears in patient in common recovery process, can avoid flatulence, improve the breast abdomen of patient's survival rate and alternately push resuscitation technique, mode hockets promptly " to press breast-pressure abdomen-pressure breast ", and after per five times (or four times) push, give lung inflation once.
This utility model is by the rescue platform, controller (1) and pneumatic source (17) are formed, it is characterized in that giving first aid to platform by pushing slide bar, electromagnetic valve, the breast abdomen of forming by pressuring gasbag replaces pressing mechanism, respiration mechanism that breathing mask and mjector are formed and supporting plate three parts are formed, pneumatic source (17) is by casing, compressor (25), filter (26), Pressure gauge (27), Flow-rate adjustment gas (33), bin (34), oil mist separator (35) and condenser (36) are formed, wherein each parts is connected by pipeline, at the port of export of this pipeline by tee T (28) respectively with the electromagnetic valve (13) of rescue platform mesothorax pressing mechanism with press pressuring gasbag (14), the electromagnetic valve of abdomen pressing mechanism (11) and press pressuring gasbag (12), the electromagnetic valve of respiration mechanism (29), mjector (15) and breathing mask (16) are connected, be connected with external oxygen cylinder (32) by tee T (30) and electromagnetic valve (31) between electromagnetic valve in respiration mechanism (29) and the mjector (15), controller (1) is made up of box body and control circuit, control circuit is by power supply (37), square-wave generator (38), frequency divider (39), d type flip flop (40), monostable flipflop group (41)-(44), press abdomen signal generator (45) and drive circuit (46)-(48) to form, the output one of square-wave generator (38) is the electromagnetic valve (13) of directly giving first aid to the breast pressing mechanism on the platform through overvoltage breast drive circuit (48) control, its output also is connected with d type flip flop (40) via frequency divider (39), the output one tunnel of monostable flipflop group (42) is connected on respiration drive circuit (46), control electromagnetic valve (29) is open-minded, the output of square-wave generator (38) and monostable flipflop (42) also is input to presses abdomen signal generator (45), and makes electromagnetic valve (11) open-minded by drive circuit (47).
Now in conjunction with the accompanying drawings this utility model being done one describes in detail.
This breast of Fig. 1 abdomen is alternately pushed the whole structural scheme of mechanism of device for resuscitating heart and pulmones.
This breast of Fig. 2 abdomen is alternately pushed the gas circuit sketch map of device for resuscitating heart and pulmones.
This breast of Fig. 3 abdomen is alternately pushed the control circuit functional-block diagram of device for resuscitating heart and pulmones.
This breast of Fig. 4 abdomen is alternately pushed the control circuit sketch map of device for resuscitating heart and pulmones.
Overall structure of the present utility model is shown in (Fig. 1).Its structure is rescue platform, controller and pneumatic source three parts.By transverse arm bar (7), straight-arm bar (3), electromagnetic valve (13), form the breast pressing mechanism by pressuring gasbag (14); Transverse arm bar (9), straight-arm bar (5), electromagnetic valve (11), press pressuring gasbag (12) and form the abdomen pressing mechanism; Breathing mask (16) and mjector (15) are formed respiration mechanism and supporting plate (2) etc. and are constituted the rescue platform.Wherein transverse arm bar (9) and straight-arm bar (5) are fixed by lock sleeve (6) and (10), and transverse arm bar (7) and straight-arm bar (3) are fixed by lock sleeve (4) and (8).
This utility model adopts civil power (220V 50HZ) power supply.At first the breast abdomen is pushed power supply (24) and (23), source of the gas (21) and (22) and breathing connector (18) connection of connection.Then input plug (20) pulled out, dock, again the trachea of external source of the gas (19) is docked, screws with the output QI KOU of pneumatic source (17) with the accessory power outlet of controller (1).At last controller (1) and pneumatic source (17) external power supply are connected civil power, get final product work.
Gas circuit of the present utility model external power supply when pneumatic source (17) shown in (Fig. 2) is connected civil power, compressor (25) is started working, air at first passes through filter (26) from air inlet, enter compressor (25), again by condenser (36), through oil mist separator (35), enter bin (34), as required, with flow regulator (33) regulate, Pressure gauge (27) shows, press pressuring gasbag (14) and electromagnetic valve (11) by electromagnetic valve (13) control breast and control abdomen and press pressuring gasbag (12) and work.Another part gas is through tee T (28), by electromagnetic valve (29), mjector (15) and respirator (16) control breathing.When needs mixing oxygen, external oxygen cylinder (32) is by electromagnetic valve (31), through tee T (30) back one-tenth mixing oxygen.
Control circuit of the present utility model is as (Fig. 3) with (Fig. 4).Power supply is general transformation, rectification, filtering, mu balanced circuit, output+5V and+24V.The circuit of other parts is shown in (Fig. 4): square-wave generator mainly is made up of 555 circuit, and its output one is directly through overvoltage breast drive circuit (48) control electromagnetic valve (13); Its output also links to each other with d type flip flop (40) via frequency divider (39), after square-wave generator produces the 4th and pulse, d type flip flop (40) utilizes trailing edge control square-wave generator (38) failure of oscillation of waveform, the output of frequency divider this moment (39) also makes monostable flipflop group loop open-minded simultaneously, trigger group (41) produces a pulse earlier, and then monostable flipflop group (42) produces a pulse, it is exported one the tunnel and is connected on respiration drive circuit (46), control electromagnetic valve (29) is open-minded, owing to square-wave generator (38) failure of oscillation this moment, electromagnetic valve (13) is closed, so have only breathing mask work, in monostable flipflop group (42) back, and then monostable flipflop group (43) and (44) produce pulse in succession, and the pulse that monostable flipflop group (44) produces makes square-wave generator (38) starting of oscillation by NAND gate and d type flip flop.The breath signal of pulse that square-wave generator (38) produces and monostable flipflop group (42) output also is input to presses abdomen signal generator (45), produce one during shortly not according to breast also no breathing and press the abdomen signal, and make by drive circuit (47) that to press abdomen electromagnetic valve (11) open-minded.Three tunnel co-ordinations, when promptly breathing both not according to breast also not according to abdomen, breathe and alternately to press abdomen four times later by breast, so go round and begin again.Generally speaking, external massage of heart and artificial respiration can use separately, do not influence its result of use.In addition, the energy adopts city (220v5OHz) low in energy consumption, need only one and plug in, but just continuous operation so that push continuous and effective, is satisfied the needs of long-time recovery.
This utility model adopts mechanical respiration and external breast abdomen alternately to push resuscitation technique, guarantees to reach medical index with science data.Use flexibly, convenient, alleviate medical personnel's labor intensity, be widely used in each hospital clinical first aid, the rescue of heart beating, respiratory arrest is played an important role.
