Abstract
The utility model discloses an instrument for promoting a severed finger live used in a severed finger reunion operation, comprising a main frame tank, an electromagnetic valve, an air pump, a finger stall bladder and a control circuit, wherein, the air pump and the finger stall bladder are communicated together through a pipeline. The indirect pressing force produced in the finger stall bladder can intermittently press the end of the severed finger to prompt the flow of the venous blood of the severed finger so as to form a new microcirculation and to improve the survival rate of the severed finger. The utility model has the advantages of simple structure, flexible use, convenient operation, and conspicuous curative effect.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly relates to the short instrument of living of a kind of replantation of amputated finger.
At present, for the case of replantation of amputated finger, in clinical practice, often because of blood vessel is stitched with mistake in operation, particularly arteries connects, and vein blood vessel does not connect fully, cause severed finger end microcirculation not smooth thus, lose blood supply, thereby cause the necrosis of severed finger end.According to relevant reported in literature, can adopt a kind of biological method to solve the not smooth problem of severed finger end microcirculation, promptly utilize a kind of biology Hirudo one by one, it is put in the severed finger end, Hirudo is about to its " mouth " and lunges the severed finger end and suck, impel blood to flow to the severed finger end, improve the microcirculatory purpose of severed finger end to reach, but this method can only make arteries circulation, and often can the generation effect to the vein blood vessel that refluxes, thereby this kind method is to the vein blood vessel impassable patient that circulates, the possibility that still can't get rid of its necrosis, and this kind animal is very rare again, if misoperation also can cause infection, thereby has brought the obstacle that is difficult to overcome for this The Application of Technology.
The purpose of this utility model be to provide a kind of by intermittence pressing method impel the short instrument of living of replantation of amputated finger of arteriovenous blood flow.
The purpose of this utility model is achieved in that the short instrument of living of this replantation of amputated finger comprises mainframe box, electromagnetic valve, air pump, fingerstall air bag and control circuit, air pump and control circuit wiring board are placed in the mainframe box, air pump and fingerstall air bag link by pipeline, are respectively equipped with inflation electromagnetic valve and exhaust solenoid valve on the inlet and outlet passage of fingerstall air bag; Its control circuit is by adjustable square-wave generator, electromagnetic relay J
1And direct current regulation circuit constitutes.
This utility model impels flowing of the interior arteriovenous blood of severed finger owing to utilize the local extruding force that produces intermittently to push the severed finger end in the fingerstall air bag, thereby can make it form new microcirculation, effectively raises the survival rate of severed finger.Adopt modern electronic technology can accurately adjust and control extruding force and intermittent time, guaranteed effect of the present utility model.Have simple in structure, applying flexible, advantage such as easy to use, evident in efficacy.
Concrete structure of the present utility model and operating position are provided by following embodiment and accompanying drawing thereof,
Fig. 1 is the overall structure sketch map of the short instrument alive of replantation of amputated finger;
Fig. 2 is the control circuit schematic diagram of the short instrument alive of replantation of amputated finger.
Describe concrete structure of the present utility model and embodiment thereof in detail below in conjunction with accompanying drawing;
The short instrument of living of this replantation of amputated finger comprises mainframe box (1), electromagnetic valve (3) (4), air pump (6), fingerstall air bag (9) and control circuit, air pump (6) and control circuit wiring board (8) are placed in the mainframe box (1), air pump (6) links by pipeline (13) with fingerstall air bag (9), is respectively equipped with inflation electromagnetic valve (4) and exhaust solenoid valve (3) on the inlet and outlet passage of fingerstall air bag (9); Its control circuit is by adjustable square-wave generator, electromagnetic relay J
1And direct current regulation circuit constitutes.
During use, fingerstall air bag (9) is enclosed within on the severed finger and with fixation clamp (10) with its secure fixation, by plug (5) and power connection, open the switch (2) on mainframe box (1) panel, air pump (6) is started working and is produced the air pressure of 20KP, simultaneously the adjustable square-wave generator that is made of " 555 " time base circuit IC2 produces the square wave of per minute 30～40 times, trigger relay J
1Make synchronous intermitten, often opening on it, normally closed two contacts are engaged by turns or disconnect.As normally opened contact J
1-1During connection, inflation electromagnetic valve P
1(4) open exhaust solenoid valve P
2(3) close, gas begins to be inflated to fingerstall air bag (9) by air pump Q (6); Work as relay J
1During release, normally opened contact J
1-1Disconnect and normally-closed contact J
1-2Engage, inflate electromagnetic valve P this moment
1(4) close exhaust solenoid valve P
2(3) open, make the gas in the fingerstall air bag (9) pass through exhaust solenoid valve P
2(3) enter atmosphere, the inflation that goes round and begins again thus, aerofluxus make the severed finger end constantly obtain intermittently extruding by fingerstall air bag (9), thereby drive flowing of blood, impel it to rebulid new blood circulation.Steadily constant for the gas that enters in the fingerstall air bag (9) is remained, can between air pump (6) and inflation electromagnetic valve (4), a constant voltage gas tank (7) be set.Can conveniently set the inflation frequency and the aeration quantity of fingerstall air bag (9) by adjusting knob (12) in the use, its result can show easily by the air gauge (11) that is located on mainframe box (1) panel.
Claims (2)
1, the short instrument of living of a kind of replantation of amputated finger comprises mainframe box (1), electromagnetic valve (3) (4), air pump (6) and control circuit, it is characterized in that: go up at air pump (6) and also be connected with fingerstall air bag (9) by pipeline (13); Air pump (6) and control circuit wiring board (8) are placed in the mainframe box (1), on the inlet and outlet passage of fingerstall air bag (9), be respectively equipped with inflation electromagnetic valve (4) and exhaust solenoid valve (3).
2, the short instrument of living of a kind of replantation of amputated finger according to claim 1 is characterized in that; At described air pump (6) is Electromagnetic air pump, also is serially connected with constant voltage gas tank (7) by pipeline between air pump (6) and the inflation electromagnetic valve (4).
