Abstract
The utility model relates to a negative pressure suction device which belongs to the field of medical devices. The technical scheme is as follows: the negative pressure suction device comprises a negative pressure sucker and a collection bottle, as well as a hose of the sucker and a flushing hose, wherein the hose of the sucker is communicated with the collection bottle, the flushing hose is communicated with a water storage device, and the water storage device is provided with a pressurization device; and the other end of the hose of the sucker and the other end of the flushing hose are connected with one end of the hose of a suction head through a transfer switch, the hose of the suction head is a two-layer sleeve, an inner pipe of the two-layer sleeve can be conducted with the hose of the sucker through the transfer switch, an outer pipe of the two-layer sleeve can be conducted with the flushing hose through the transfer switch, an end socket of the inner pipe is open, and the end socket of the outer pipe is the suction head. The negative pressure suction device has simple structural design, and the suction head can be conveniently flushed even in an operation without delaying the operation process.
Description
Technical field
The assistive device of using when this utility model relates to a kind of the operation relates in particular to a kind of negative pressure suction device that can prevent to attract the head obstruction.
Background technology
At present the attraction head of the negative pressure suction device that uses of surgery stops up easily, influences in the operation process attraction to hemorrhage, dirt and chip, thereby has reduced operation efficient.The cleaning that attracts head is not had special-purpose instrument yet,, therefore, had a strong impact on the efficient of operation so cleaning is also cumbersome.
Summary of the invention
This utility model is at the existing in prior technology shortcoming, and provides a kind of structural design simple, even also can not delay the technical scheme of the negative pressure suction device of operation process easily to attracting head to wash in operation.
This utility model is realized by following technical measures: a kind of negative pressure suction device, it comprises vacuum extractor, receiving flask, it also comprises suction pump flexible pipe and flushing flexible pipe, described suction pump flexible pipe is communicated with receiving flask, the flushing flexible pipe is communicated with accumulator, and described accumulator is provided with pressue device; The other end of described suction pump flexible pipe and flushing flexible pipe is connected with an end that attracts the flaccidity of the neck pipe by change-over switch, described attraction flaccidity of the neck pipe is a bilayer sleeve, the interior pipe of bilayer sleeve by change-over switch can with the conducting of suction pump flexible pipe, the outer tube of bilayer sleeve by change-over switch can with flushing flexible pipe conducting, the termination of pipe is open in described, and the termination of described outer tube is for attracting head.
Concrete characteristics of the present utility model also have, and suction pump flexible pipe and flushing flexible pipe adopt double lumen tube, and the lower end bifurcated of double lumen tube is communicated with receiving flask, accumulator respectively.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because having adopted attraction flaccidity of the neck pipe is the structural design of bilayer sleeve, can switch interior pipe and the conducting of suction pump flexible pipe or outer tube and the conducting of flushing flexible pipe easily by change-over switch, its structural design is simple, easy to operate, also can wash conducting apace even attract head to stop up in the operation, can not delay the process of operation.
