The utility model discloses a negative pressure filter, which comprises a male joint and a female joint, wherein the male joint and the female joint are axially provided with through stepped holes, one end of the male joint is in threaded sealing connection with one end of the female joint, the other end of the male joint is provided with a pipe joint, and the step of the inner hole of the female joint is provided with a filter screen; the utility model discloses simple structure is reliable, and the filter effect is good, and the leakproofness is good, and convenient the dismantlement is washd, can guarantee that different patients inhale the phlegm safely at any time as required.
Description
Technical field
The utility model relates to a kind of medicine equipment, especially relates to a kind of negative pressure filtration device.
Background technology
At present; mainly be that many negative-pressure pipelines directly are connected on the total negative pressure device clinically when carrying out vacuum suction to patient; can carry out vacuum suction to a plurality of patients simultaneously; the hidden installation of negative-pressure pipeline; pipe interior arranges screen pack; foul in the disease population stops up in the position of negative-pressure pipeline inner filtration net easily; in case stop up; the pipeline that must take hidden installation apart cleans; waste time and energy, if screen pack is not installed, then cause the plugging fault of negative pressure device easily in the middle of pipeline; negative pressure device is in case stop up; must shut down and clean and maintenance, make all negative pressure terminals all can not use, extremely inconvenient; this moment, just possibility was accidents caused if there is patient to be badly in need of using vacuum suction, perhaps influenced the normal wash of negative pressure device.
The utility model content
The utility model aims to provide a kind of negative pressure filtration device, can filter respectively each negative pressure pipe, can not influence the normal use of other vacuum suction pipe when the filter of certain root vacuum suction pipe is cleaned, and sucks and can in time clear up, and is easy to use.
The technical solution of the utility model is a kind of negative pressure filtration device, comprise male joint and female joint two parts, both axially all have penetrating shoulder hole, and both thread seals connect, male joint and the female joint other end are interface tube, and the step place is provided with filter screen in the female joint.
Preferably, described male joint is that taper thread is connected with female joint.
Preferably, described male joint and female joint are cylindrical thread, and internal threaded end is provided with sealing ring in the female joint.
Preferably, described sealing ring is rubber seal.
Preferably, described female joint small aperture is 3mm-6mm, and macropore diameter is 9mm-17mm, and the male joint small aperture is 3mm-6mm, and macropore diameter is 6mm-14mm.
Further, all there is hex nut shape structure described male joint, female joint body outside.
The utility model is simple and reliable for structure, and is easy to use, can in time clean after the use, do not influence the normal use of other negative pressure terminal during cleaning, can guarantee each patient's use needs at any time, low cost of manufacture, good filtration effect, good airproof performance.

Fig. 4 is the utility model structure side view;
Among the figure: 1-interface tube, 2-filter screen, 3-sealing ring, 4-female joint, 5-internal thread, 6-external screw thread, 7-male joint.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figures 1 to 4, the utility model discloses a kind of negative pressure filtration device, comprise male joint 7 and female joint 4 two parts, both axially all have penetrating shoulder hole, and both thread seals connect, and male joint 7 and female joint 4 other ends are interface tube 1, and the step place is provided with filter screen 2 in the female joint 4.
Preferably, male joint 7 is connected for taper thread with female joint 4.
Preferably, male joint 7 and female joint 4 are cylindrical thread, and internal thread 5 ends are provided with sealing ring 3 in the female joint 4.
Preferably, sealing ring 3 is rubber seal.
Preferably, female joint 4 small apertures are 3mm-6mm, and macropore diameter is 9mm-17mm, and male joint 7 small apertures are 3mm-6mm, and macropore diameter is 6mm-14mm.
Further, all there is hex nut shape structure male joint 7, female joint 4 body outsides, conveniently tighten and dismantle by instrument.
During operation, the external screw thread 6 of male joint 7 one ends and the internal thread 5 in the female joint 4 are linked together, suction pipe one end is connected on the interface tube 1 of female joint 4, the other end is connected on the negative pressure terminal interface, another root suction pipe one end is connected on the interface tube 1 of male joint 7, and the other end stretches into and carries out vacuum suction in patient's cavum laryngis; When the bulky grain foul in the sucking-off patient cavum laryngis, filter screen 2 in the female joint 4 can block foul, foul is stayed in female joint 4 and male joint 7 endoporus, when this patient does not need vacuum suction, female joint 4 and male joint 7 disassembled and clean foul, thereby can not have influence on the work of sputum aspirator or negative pressure equipment.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
