Abstract
The invention relates to a negative pressure suction mechanism on a haemorrhoids loop ligature device. The negative pressure suction mechanism is characterized by comprising an air inlet valve trigger, a fixed pipe and an air cylinder, the bottom of a piston of the air cylinder is connected with the air inlet valve trigger through a movable pull rod, an air inlet one-way valve and an air outlet one-way valve are arranged on an air outlet of the air cylinder, the air inlet one-way valve is communicated with the fixed pipe through a pipeline, an air vent valve is arranged on a pipeline between the air inlet one-way valve and the fixed pipe, a baroceptor is installed on the air outlet valve and is connected with a PCB through a wire, and a digital display screen used for displaying air pressure is arranged on the PCB. The negative pressure suction mechanism is reasonable and simple in structure, the baroceptor and the digital display screen are used in cooperation, the air pressure state can be observed and controlled in real time, and it is avoided that a patient feels uncomfortable.
Description
Technical field
The present invention relates to a kind of haemorrhoids ligation apparatus, be specifically related to the vacuum suction mechanism 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 usually, under local anesthesia or other anesthesia, is completed by operator hand operation, not only time-consuming, require great effort, 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 namely 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.
Summary of the invention
The technical problem to be solved 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.
This invention address that the technical scheme that the problems referred to above adopt 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, it is respectively arranged with breather check valve and outgassing nonreturn valve at the gas outlet place 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, it is an advantage of the current invention that:
The vacuum suction mechanism of the present invention rational in infrastructure, simply, coordinates baroceptor and the digital display screen can real-time monitored and control atmospheric pressure state, it is to avoid patient is caused sticky feeling simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
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, the present invention is described in further detail.
Referring to Fig. 1, the present invention 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 place 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 producing negative pressure in fixing pipe 2, pipeline between described breather check valve 5 and fixing pipe 2 is provided with vent valve 7, 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, it is prevented that patient is caused unnecessary impact by observing digital display screen.
In addition to the implementation, present invention additionally comprises the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, all should fall within the protection domain of the claims in the present invention.
