Abstract
The utility model discloses an ordinary and military application dual-purpose pedal negative pressure aspirator, which comprises a negative pressure generator, a driving part, a pressure buffer air bag, a liquid storage bottle and a suction pipe. Main bodies of the negative pressure generator are a piston and a pneumatic cylinder. An end cover, an air inlet check valve and an exhaust check valve are arranged on the pneumatic cylinder. The pressure buffer air bag is a soft bag body with the bag wall thickness which becomes thinner from an inlet portion and an outlet portion toward the middle, can has a buffer effect on changes of pressure intensity of negative pressure in a certain range and enables suction force to be proper and even. The manual-operated aspirator is compact in structure and reasonable in design.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and it is dual-purpose to relate in particular to a kind of flat war, suction suitably, foot-operated vacuum extractor uniformly.
Background technology
Suction pump is as a kind of medical apparatus and instruments, often be used in the middle of the rescue and treatment of hurting sb.'s feelings patient, it can help the wounded that the dirty thing in the respiratory tract is attracted out, make respiratory smooth, also can attract the blood of surgical patient wound and various secretions out, and then clear up wound and expose surgical field of view to the open air, common in the prior art have electric suction apparatus and a pneumatic suction pump, electric suction apparatus attracts effective, but its volume is big, be not easy to carry, be unsuitable in outdoor application, and when the power supply supply goes wrong, can't operate as normal, though it is big that pneumatic suction pump commonly used has solved the electric suction apparatus volume, rely on the drawback of power supply supply, but its suction size is non-adjustable, uses certain limitation, therefore needs a kind of advantage of existing pneumatic suction pump small body type, the suction pump that can be controlled the suction of its generation is used as the higher medical apparatus and instruments of a kind of cost performance and uses for medical personnel again.
The utility model content
In view of this, the purpose of this utility model provides the dual-purpose foot-operated vacuum extractor of a kind of flat war, can effectively help user to attract the dirty thing in the respiratory tract or the blood and the secretions of wound, and suction suitably, evenly, and is simple to operate, easy to carry.
The dual-purpose foot-operated vacuum extractor of flat war of the present utility model, comprise negative pressure maker, driver part and suction catheter, described negative pressure maker comprises cylindric pneumatic cylinder, be arranged at the foraminous end cap in center of pneumatic cylinder mouth and be arranged at breather check valve and outgassing nonreturn valve on the pneumatic cylinder bottom outer wall diametric(al); Described driver part comprises piston, connecting rod, back-moving spring and pedal, wherein piston is arranged at pneumatic cylinder inside, the fixedly connected pedal in the upper end of connecting rod, and the lower end is passed the hole at end cap center and is fixedly connected on piston, back-moving spring is sheathed on the connecting rod, is against between end cap and the pedal; Described suction catheter is connected on the breather check valve, is positioned at the suction catheter medium position and also is provided with liquid containing bottle.
Further, one section suction catheter between breather check valve and the liquid containing bottle is provided with buffering pressure air-pocket;
Further, described buffering pressure air-pocket is a wall thickness by the import and export place to the centre soft utricule of attenuation gradually;
