Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of external chest compression device.
Background technology
Cardiopulmonary arrest and loss of consciousness are clinical common dangerous situations, and the general mode by closed cardiac massage carries out cardio-pulmonary resuscitation clinically.Closed cardiac massage in the past adopts free-hand operation usually, and pressing dynamics and pressing interval control by rule of thumb, and operating effect varies with each individual, and rescue effect is not good.At present, also the automation for closed cardiac massage is had to occur, this kind of device adopts fixing band to be fixed on front side of patient usually, to the applying pressure of pressing place intermittent, but often by design limit, it is difficult to firm being fixed, easily rock in pressing process, and the impulsive force produced during its pressing is comparatively violent, is difficult to reach best pressing effect, and easily pressing too fiercely causes patient's fracture of rib, increase the life danger of patient further.
Utility model content
For overcoming above-mentioned technical problem, it is simple that this utility model provides a kind of structure, and use safety, convenience, press effective external chest compression device.
For realizing above-mentioned technical purpose, this utility model is by the following technical solutions: a kind of external chest compression device, comprise an inverted cylinder, piston and piston rod is provided with in cylinder, be provided with a post chamber in piston rod, this post intracavity is provided with a plunger, is provided with spring between its upper end and top, post chamber, the lower end of plunger is connected with push rod, and the below of push rod is provided with pressing plate; The lower end of described piston rod is provided with the threaded cap limiting plunger downstream position, and this threaded cap is provided with the centre bore passed for push rod; The turnover air pipe at described cylinder two ends is connected with air pump through a reversal valve, and air pump provides Pneumatic pressure power for cylinder, and reversal valve control cylinder stretches stroke; Described pressing plate is installed on pressure transducer; Above-mentioned air pump, reversal valve and pressure transducer control duty by controller; The medium position of the inner arc side of a segmental support is fixed in described cylinder upper end, and the two ends of this segmental support are connected with the two ends of a fixing band respectively, and this fixing band is provided with length-adjustment buckle.
This utility model has following beneficial effect: in use, fixing band is utilized segmental support to be fixed on the front side of patient, pressing plate is made to be positioned at pressing position on front side of patient's breastbone, during unlatching work, air pump provides operating air pressure through reversal valve to cylinder, under the control of reversal valve, piston rod drives pressing plate to move up and down by retreating, and then plays the object of pressing.Because this device works under control of the controller, the interval of pressing is accurate and adjustable; Due to pressing plate being installed on pressure transducer, actual press pressure can be fed back to controller by it, and then unlikely pressing force is spent large and damages patient; Owing to being provided with the buffer gear of spring and plunger formation between piston rod and pressing plate, make pressing compare mitigation, simulate action during artificial pressing, there is good rescue effect; Because cylinder and appurtenances thereof provide support by segmental support, and segmental support two ends span is large, and be fixed on after on patient body through fixing band, comparatively firm, the cylinder that can be in work provides stable support, can not shake and affect pressing effect.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is cylinder and below link structural representation thereof.
In figure, 1, fixing band, 2, pressure transducer, 3, segmental support, 4, pressing plate, 5, spring, 6, reversal valve, 7, controller, 8, air pump, 9, piston, 10, plunger, 11, piston rod, 12, cylinder, 13, push rod, 14, threaded cap, 15, length-adjustment buckle, 16, post chamber.
Detailed description of the invention
Shown in Fig. 1,2, a kind of external chest compression device disclosed in this utility model, it comprises an inverted cylinder 12, is provided with piston 9 and piston rod 11 in cylinder 12, and the top of so-called inversion and piston rod 11 is down; Be provided with a post chamber 16 in piston rod 11, be provided with a plunger 10 in this post chamber 16, be provided with spring 5 between plunger 10 upper end and top, post chamber 16, the lower end of plunger 10 is connected with push rod 13, and the below of push rod 13 is provided with pressing plate 4; The lower end of described piston rod 11 is provided with the threaded cap 14 limiting plunger 10 downstream position, and this threaded cap 14 is provided with the centre bore passed for push rod 13; The turnover air pipe at described cylinder 12 two ends is connected with air pump 8 through a reversal valve 6, and air pump 8 provides Pneumatic pressure power, the flexible stroke of reversal valve 6 control cylinder 12 for cylinder 12; Described pressing plate 4 is installed on pressure transducer 2; Above-mentioned air pump 8, reversal valve 6 and pressure transducer 2 control duty by controller 7; The medium position of the inner arc side of a segmental support 3 is fixed in described cylinder 12 upper end, and the two ends of this segmental support 3 are connected with the two ends of a fixing band 1 respectively, and this fixing band 1 is provided with length-adjustment buckle 15.
In use, utilize fixing band 1 that segmental support 3 is fixed on the front side of patient, pressing plate 4 is made to be positioned at pressing position on front side of patient's breastbone, during unlatching work, under control of the controller 7, air pump 8 provides operating air pressure, under the control of reversal valve 6 to cylinder 12 through reversal valve 6, piston rod 11 drives pressing plate 4 to move up and down by retreating, and then plays the object of pressing.Wherein, compression frequency, pressing dynamics are all preset by controller 7.
Because this device works under controller 7 controls, the interval of pressing is accurate and adjustable; Due to pressing plate 4 being installed on pressure transducer 2, actual press pressure can be fed back to controller 7 by it, and then unlikely pressing force is spent large and damages patient, and more than press pressure is too little again, does not have the pressing effect of expection; Owing to being provided with the buffer gear that spring 5 and plunger 10 are formed between piston rod 11 and pressing plate 4, make pressing compare mitigation, simulate action during artificial pressing, there is good rescue effect; Because cylinder 12 and appurtenances thereof provide support by segmental support 3, and segmental support 3 two ends span is large, be fixed on after on patient body through fixing band 1, comparatively firm, the cylinder 12 that can be in work provides stable support, can not shake and affect pressing effect.
