Abstract
The utility model discloses a kind of filters, including shell, filter paper is provided in shell, one end of shell is provided with opening, and the two sides of shell are respectively arranged with extension item, extension item is located at case inside and is provided with slot, it is plugged with bar shaped bar in slot, fixing groove is provided in bar shaped groove sidewall, the fixed strip being plugged in fixing groove is provided on bar shaped bar, the side of bar shaped bar inwardly is provided with strip groove, and the side of filter paper is stuck in strip groove.The utility model has the following advantages that and effect: extending item by setting, the both ends of filter paper are fixed, so that reducing colloid on traditional approach is easy the problem of overflowing and occupying excessive filter area, increase filter efficiency.
Description
Technical field
The utility model relates to technical field of medical equipment, in particular to a kind of filter.
Background technique
In current clinical medicine, effective means of the ventilator as an energy artificial substituting expiratory positive airway pressure function is general
All over for anesthesia respiration management, Breathing Suppotion treatment and the emergency resuscitation during respiratory failure, major operation caused by a variety of causes
In, highly important position is occupied in Modern Medical Field.Ventilator is that one kind can play prevention and treatment respiratory failure,
Complication is reduced, the vital Medical Devices of patients ' lives are saved and extend.
Filter used for respirators in the prior art, usual shell are plastic part, and the filter paper surrounding in plastic part is logical
The generation of colloid and plastic part is crossed to be fixedly connected so that using when filter paper will not be subjected to displacement.But in which, due to colloid
It is often overflowed to intermediate direction, so that the filter area of filter paper becomes smaller, the working efficiency of the ventilator is caused to reduce.
Utility model content
The purpose of the utility model is to provide a kind of filters that the effciency of respiratory is high.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of filter, including
Shell is provided with filter paper in shell, and one end of shell is provided with opening, and the two sides of shell are respectively arranged with extension item, extends
Item is located at case inside and is provided with slot, and bar shaped bar is plugged in slot, is provided with fixing groove in bar shaped groove sidewall, on bar shaped bar
It is provided with the fixed strip being plugged in fixing groove, the side of bar shaped bar inwardly is provided with strip groove, and the side of filter paper is stuck in item
In shape slot.
By using above-mentioned technical proposal, filter paper is stuck in bar shaped, by the movement of bar shaped bar be driven from be open into
Enter in shell, and guarantee the stabilization of bar shaped bar by the mutual cooperation of fixing groove and fixed strip, realizes and filter paper is fixed on shell
Intracorporal purpose, increases filter area, ensure that filter efficiency.
It is further arranged to: being provided with several jacks on bar shaped bar, inserted link is provided in jack, one end of inserted link contradicts
On filter paper, the other end is contradicted on the side wall of slot.
By using above-mentioned technical proposal, inserted link can be contradicted on filter paper, and filter paper is fixed, and be prevented
Filter paper is easily separated from the problem of bar shaped bar when shell interior air-flow passes through.
Be further arranged to: the section of the inserted link be it is rectangular, one end of inserted link towards the side wall of slot is provided with inclination
Slope, inclination slope aspect increase far from housing direction.
By using above-mentioned technical proposal, the setting of inclined slope enable to inserted link when bar shaped bar is admitted to slot more
Convenient, rectangular inserted link can guarantee that the direction of inclined slope will not deflect.
Be further arranged to: the inserted link is provided with pressure reducing disc towards filter paper one end.
By using above-mentioned technical proposal, inserted link can be reduced and contradict the pressure applied on filter paper, increase filtering
The durability of paper.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the utility model filter；
Fig. 2 is the enlarged drawing in Fig. 1 at A.
In figure: 1, shell；2, filter paper；3, it is open；4, extend item；5, slot；6, bar shaped bar；7, fixing groove；8, fixed
Item；9, strip groove；10, jack；11, inserted link；12, inclined slope；13, pressure reducing disc.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of filter, is used primarily in the filtering to gas in ventilator, including shell 1, and one end of shell 1 is provided with out
Mouth 3, opening 3 make shell 1 keep sealing by installing end cap.The two sides of opposed open 3, which are provided with, on shell 1 extends item 4,
Extend item 4 and the side inside shell 1 is provided with slot 5, the top side wall of slot 5 is provided with the fixing groove 7 of a bar shaped, slot
It is plugged with a bar shaped bar 6 in 5, the side of fixing groove 7 is provided with fixed strip 8, fixed strip 8 and 7 phase of fixing groove on bar shaped bar 6
Mutually adaptation, so that 6 grafting of bar shaped bar is into being able to maintain fixation after slot 5.
The side of bar shaped bar 6 towards shell 1 is provided with a strip groove 9, is provided with filter paper 2, filter paper between strip groove 9
2 middle position has wavy fold.The upper surface of bar shaped bar 6 is provided with 6 rectangular jacks of perforation strip groove 9
10, a root cutting bar 11 is plugged in each jack 10.
One end that inserted link 11 is located in strip groove 9 is provided with circular pressure reducing disc 13, and pressure reducing disc 13 is contradicted in filter paper 2
On.
The other end on inserted link 11 with respect to pressure reducing disc 13 is provided with inclined slope 12, and inclined slope 12 is inclined to far from 1 direction of shell
It is arranged obliquely, when so that bar shaped bar 6 being penetrated slot 5, inclined slope 12 can contradict upper with respect to slot 5 on extending item 4
On square inner wall, and inserted link 11 is automatically compressed filter paper 2.Pressure reducing disc 13 can reduce what inserted link 11 applied filter paper 2
Pressure increases the durability of filter paper 2 so that the both ends of filter paper 2 are not susceptible to breakage.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
