SUMMERY OF THE UTILITY MODEL
An apparatus for one-time rapid examination and cleaning of a sputum suction tube comprises a bag body containing physiological saline; a piercing structure for piercing the capsule; the sputum suction device is characterized in that the puncturing structure is arranged inside the bag body, and a bag nest into which a sputum suction pipe extends is arranged on the bag body; the direction of the puncture structure is opposite to the direction of the sac pit. Through will inhale the phlegm pipe and set up to the bag nest in, the puncture structure is pressed to back borrow the pushing down force of inhaling phlegm pipe itself or nursing staff's hand, makes puncture structure pierce through the bag nest, and the liquid in the utricule then can be through inhaling the phlegm pipe entering and inhaling the phlegm pipeline under the negative pressure effect, reachs and detects the purpose of inhaling the unobstructed nature of phlegm pipeline or slope and inhaling the phlegm pipeline. Because the capsule body is in a closed state before use, the normal saline in the capsule body can not be exposed in the air for a long time, the possibility of pollution is reduced, the normal saline in the capsule body is specific, and the problem of waste and liquid dumping can not occur when one capsule body is used every time.
Further, pierce through the structure setting inside the utricule, set up and just to the pocket setting in the utricule side, during the use, press through medical personnel and realize stabbing the utricule in pocket department, reach the purpose with the interior liquid suction of utricule through the negative pressure suction.
Further, the sac nest is arranged at the eccentric position of the sac body, the piercing structure is arranged on the side face of the cancer sac body, and the distance between the side face of the sac nest with the smaller distance and the side face of the sac body is less than 3 mm; the puncture structure is arranged on the side surface of the capsule body, and the distance between the tip of the puncture structure and the nearest side surface of the capsule nest is less than 2 mm; greater than 1 mm; the arrangement can ensure the safety of the sac body and ensure that medical staff can puncture the side surface of the sac pit with slight force.
Or, pierce through the structure setting inside the utricule, set up in the utricule bottom and just to the bag nest setting, during the use, will inhale the phlegm pipe through medical personnel and stretch into in the bag nest and press bag nest bottom, reach and pierce through the structure and stab the purpose of breaking the bag nest, further reach the purpose with the interior liquid suction of utricule through the negative pressure suction.
Further, the pocket is arranged in the middle of the pocket body, and the distance between the bottom surface of the pocket and the bottom surface of the pocket body is less than 5 mm; the puncture structure is arranged at the bottom of the capsule body, and the distance from the tip of the puncture structure to the bottom of the capsule nest is less than 3 mm; greater than 1 mm; the arrangement can ensure the safety of the bag body and ensure that the piercing structure can pierce the bottom of the bag pit easily.
Further, the bag nest is cylindrical bag nest, and the diameter is not more than inhales the diameter of phlegm pipe, and this kind of setting can be guaranteed to inhale the in close contact with of phlegm pipe with the bag nest, and when detecting the connectivity, the utricule has used up and need borrow medical personnel and take off the utricule from inhaling the phlegm pipe with the utricule, when carrying out the washing operation after, need not take off the utricule, together with inhale the phlegm pipe abandon the garbage bin in the lump can.
Furthermore, the puncturing structure is a plastic needle with higher hardness and is integrally connected with the capsule body, so that effective puncturing can be guaranteed, and the physiological saline cannot be polluted.
Further, the whole bottom surface of utricule is circular plane, and a hard board is pasted to circular plane bottom, sets up double faced adhesive tape under the hard board and pastes or little sucking disc, can paste or little sucking disc through double faced adhesive tape during the use is fixed the utricule to the operation panel, mainly to using when detecting the connectivity, can examine the back directly will inhale the phlegm pipe take off can, can not have the utricule along with inhaling the problem that the phlegm pipe removed.
Furthermore, the whole lateral surface of utricule is cylindrical, and this kind of structure is conveniently set up.
Furthermore, a cover film is arranged on the sac pit, and the cover film is taken down when in use, so that the operation complexity is increased, but the antifouling property of the physiological saline can be further improved.
Furthermore, a placing box for containing the bag body is arranged, a plurality of small cavities for containing the bag body are arranged on the placing box, a covering cover is arranged above each small cavity at intervals, and each covering cover is provided with an extending hole for extending the sputum suction tube and corresponding to the position of the bag pit; the bag body in the small cavity with the covering cover is mainly used for detecting the connectivity; the bag body in the small cavity without the cover is used for cleaning the sputum suction pipeline.
Further, the cover is a cover which can be opened and locked, and any cover body which can be opened and locked in the prior art can be used.
Furthermore, each placing box is provided with 6-10 small cavities, the arrangement can meet most of sputum suction requirements, and the sputum suction box can be left for next reuse when the sputum suction box is not used up and cannot be polluted.
The whole transparent plastic material that is of box is placed to further, makes things convenient for the observation to the intracavity condition, prevents to insert in the utricule that uses up.
Further, place box bottom portion and set up the small suction cup that will place the box and fix to the operation panel, this kind of setting can conveniently place the used repeatedly of box, still can not leave the vestige.
Furthermore, the material of the bag body is soft elastic material, and the thickness of the material at the bag body and the bag nest is different, so that the structure with the effective bag nest is formed.
Furthermore, the bag body is 5-10ml in volume, and the volume setting can meet the inspection of connectivity during most sputum suction and the cleaning of the sputum suction pipeline after sputum suction.
Further, set up the utricule of inspection connectivity and wash the utricule of inhaling the phlegm pipeline, both volumes are different, and this kind of setting is mainly to the demand of liquid when satisfying two operations, prevents the wasting of resources that the capacity too big caused.
Compare with prior art's direct suction bent dish normal saline's mode, the utility model discloses a technical scheme of utricule can effectually save normal saline's preparation time, and is safer in the operation process.
Detailed Description
The cover can be an openable cover body commonly used in the prior art, a specific structure is not shown in the attached drawings, and the understanding of the scheme by the technical personnel in the field is not affected.
