Abstract
The utility model relates to a vacuum aspiration mechanism on haemorrhoids ligation device, its characterized in that: it includes admission valve trigger, fixed pipe and cylinder, the piston bottom of cylinder links to each other with the admission valve trigger through the active pull rod the gas outlet punishment of cylinder do not is provided with admit air check valve and air outlet one -way valve, the check valve that admits air is linked together through pipeline and fixed pipe admit air and be provided with the bleed valve on the pipeline between check valve and the fixed pipe the baroceptor is installed to the bleed valve position, the baroceptor passes through the wire and links to each other with the PCB board be provided with the digital display screen who is used for showing atmospheric pressure on the PCB board. The utility model discloses a vacuum aspiration structure of mechanism is reasonable, and is simple, cooperates baroceptor and digital display screen can survey with controlling the air pressure the state in real time simultaneously, avoids causing the sticky feeling to the patient.
Description
Technical field
This utility model relates to a kind of haemorrhoids ligation apparatus, the vacuum suction mechanism being specifically related on a kind of haemorrhoids ligation apparatus.Belong to technical field of medical instruments.
Background technology
Hemorrhoid ligation is the common method for the treatment of hemorrhoid, and general hemorrhoid are had good curative effect.But the hemorrhoid Loop ligature implemented clinically at present is typically under local anesthesia or other anesthesia, operator hand operation complete, the most time-consuming, laborious, appear difficulty, and easily cause bleeding and pain.In order to alleviate patient suffering and operating difficulty, people have thought that multiple method improves, and as negative-pressure sucking overlaps hypodesmus, it is made up of negative pressure suction nozzle, negative pressure generator and connecting tube etc..By negative pressure generator by blood stasis negative suction suction nozzle, simultaneously plastic loop ligation at blood stasis root, block blood fortune, make blood stasis because of ischemic necrosis, come off.Due to currently used negative-pressure sucking set hypodesmus, its negative pressure generator is circumscribed, and when i.e. implementing operation, negative pressure suction nozzle, negative pressure generator need two people's operations, and therefore, vacuum magnitude is difficult to control to, and adds operating difficulty.
Utility model content
Technical problem to be solved in the utility model is to provide the vacuum suction mechanism on a kind of haemorrhoids ligation apparatus for above-mentioned prior art, can observe the looping and binding device pressure when adsorbing hemorrhoid, it is to avoid patient causes pain or uncomfortable.
The technical scheme in the invention for solving the above technical problem is: the vacuum suction mechanism on a kind of haemorrhoids ligation apparatus, it includes intake valve trigger, fixing pipe and cylinder, the piston base of described cylinder is connected with intake valve trigger by active pull rod, breather check valve and outgassing nonreturn valve it is respectively arranged with at the gas outlet of described cylinder, described breather check valve is connected with fixing pipe by pipeline, and the pipeline between described breather check valve and fixing pipe is provided with vent valve.
Preferably, being provided with baroceptor in described vent valve position, described baroceptor is connected with pcb board by wire, is provided with the digital display screen for showing air pressure on described pcb board.
Compared with prior art, the utility model has the advantage of:
Vacuum suction mechanism of the present utility model rational in infrastructure, simply, coordinates baroceptor and the digital display screen can be with real-time monitored with control atmospheric pressure state, it is to avoid patient is caused sticky feeling simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
Intake valve trigger 1, fixing pipe 2, cylinder 3, active pull rod 4, breather check valve 5, outgassing nonreturn valve 6, vent valve 7, baroceptor 8, pcb board 9, digital display screen 10.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
See Fig. 1, this utility model relates to the vacuum suction mechanism on a kind of haemorrhoids ligation apparatus, including intake valve trigger 1, fixing pipe 2 and cylinder 3, the piston base of described cylinder 3 is connected with intake valve trigger 1 by active pull rod 4, breather check valve 5 and outgassing nonreturn valve 6 it is respectively arranged with at the gas outlet of described cylinder 3, described breather check valve 5 is connected with fixing pipe 2 by pipeline, pull intake valve trigger 5, active pull rod 4 is driven to pull down piston, gas is entered cylinder 3 from fixing pipe 2 by breather check valve 5, thus in fixing pipe 2, produce negative pressure, it is provided with vent valve 7 on pipeline between described breather check valve 5 and fixing pipe 2, by starting vent valve 7 so that the negative pressure in fixing pipe 2 discharges；
In order to realize the detection of pressure, in described vent valve 7 position, baroceptor 8 is installed, described baroceptor 8 is connected with pcb board 9 by wire, described pcb board 9 is provided with the digital display screen 10 for showing air pressure, Stress control can be realized by observation digital display screen, prevent from patient is caused unnecessary impact.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
