Exempt from button the mask
The application is that application No. is the divisional applications of 201610227567.1 applications for a patent for invention.
Technical field
The present invention relates to a kind of medical instrument, especially a kind of medical respiratory masks, and in particular to one kind is without laborious button
Pressure exempts from button the mask.
Background technology
It is well known that breathing mask must be used in surgery anesthesia and rescue.Medical mask currently on the market is most
Number is the air-filled cushion product made of PVC material.It is using wearing process, and medical staff is needed to go out larger strength
Mask can be buckled to air-tight state, larger extruding can be generated to the snout of patient in this way;It simultaneously will also be in conjunction with four-tailed bandage
Fixation also increases several step operation sequences, and use is extremely inconvenient.
To overcome drawbacks described above, occur some modified medical masks in the market, such as application No. is
201220562610.7 Chinese utility model patent discloses a kind of convenient breathing mask of pressing, it includes cover body (1),
The upper end of cover body (1) is equipped with tubulose snorkel (2), and the lower end of cover body (1) is equipped with the airbag structure (3) being in contact with human body, cover
Body (1) is equipped with to press the force application structure (4) so that mask and human body oral-nasal perimeter tight sealing contact.This kind of structure
Although medical mask can mitigate the work load of medical staff significantly, have the advantages that pressing is convenient, laborsaving, and human body
The part of contact is airbag structure, and contact of the air bag with human body is " point-to-point ", and oxygen is easily leaked from mask and patient contact surface
Go out, poor sealing, button, which is worn, to be still more troublesome.
Invention content
In view of the above-mentioned deficiencies, technical problem to be solved by the invention is to provide a kind of simple in structure, good airproof performance,
Button wears convenience, button the mask is exempted from labour-saving.
To solve the above problems, the invention is realized by the following technical scheme:
Exempt from button the mask, including cover body, the snorkel for accessing oxygen is equipped in the upper end of cover body, further includes hood pad and for solid
Determine the fastener of mask, one end of the fastener be movably hinged on the side wall outside snorkel, its other end is as the effect buckled
End, the hood pad are made of soft material and are fixed on the interior lateral margin of cover body lower end, when wearing, the face of hood pad and wearer
Portion's skin is seamless applying.
In said program, the hood pad may include upper ring and the lower ring that is connected as one with upper ring, upper ring and cover body
Lower end connects, and the diameter of upper ring is less than the diameter of lower ring.
In said program, it is further preferred that the hood pad is specifically as follows the silicagel pad made of silica gel material.
In said program, for the ease of fastener for installing, while can also up and down adjustment fastener mounting height, in snorkel
It is above movable to be arranged with a cutting ferrule.
In said program, the fastener includes brace and cross bar, and one end of the brace is articulated on cutting ferrule, its is another
End is connected as one with cross bar, and the cross bar is fastener horizontally disposed and that oblique L-shaped structure is constituted with brace.
In said program, part is broken equipped with one in the end of the cross bar, in order to which when needing to remove mask, energy is quickly
Ground peels off fastener.
In said program, further specifically, cross bar is in 45 °~90 ° angles with the oblique L-shaped structure that brace is constituted.
Beneficial effects of the present invention are:
1, mask can be snapped in the face of patient well by the present invention by the fastener being mainly made of brace and cross bar, and
In the process of wearing without special exhaust and firmly standard operations such as pressing, as long as and mask to be directed to the snout of patient
After light pressure, then the cross bar of fastener is buckled in the lower jaw part of patient, that is, completed, it is simple to operate, effortlessly, and reduce because
Breathing mask is worn to the extruding dynamics of patient's snout, improves patient comfort;
2, the present invention replaces traditional airbag structure, air bag using the hood pad structure for being made of up-narrow and down-wide collar shape silica gel
Structure and the contact of patient facial region's skin are point contact, and hood pad made of the silica gel used is cyclic annular, with patient contact
It is contacted for face;The stickup to skin and retractility along with silica gel effectively enhance air-tightness and the fitting of mask in this way
Degree, to prevent oxygen from leaking out.

Specific implementation mode
With reference to specific embodiments and the drawings, explanation that the present invention will be further explained, but not limiting this hair
It is bright.
As shown in Figure 1, exempt from button the mask, including cover body 2, it is equipped with the snorkel 1 for accessing oxygen in the upper end of cover body 2,
Movable sleeve is equipped with a cutting ferrule 5 on snorkel 1, and the cutting ferrule 5 can be specifically the intermeshing locking plate of two panels, can also be tool
The cutting ferrule 5 of flexible lantern ring either other structures.Further include hood pad 3 and the fastener for fixing mask, the fastener
One end be movably hinged on the side wall outside snorkel 1, its other end as buckle effect end.The hood pad 3 is by soft material
Be made and be fixed on the interior lateral margin of 2 lower end of cover body, when being worn on patient facial region, hood pad 3 and skin of face it is seamless applying.
Specifically, the fastener include brace 4-1 and cross bar 4-2, the brace 4-1 one end be articulated on cutting ferrule 5,
Its other end is connected as one with cross bar 4-2, and the cross bar 4-2 is horizontally disposed and constitutes oblique L-shaped structure with brace 4-1
Fastener.Part 6 is broken equipped with one in the end of cross bar 4-2, in the present embodiment, the part 6 of breaking is the nose bar reversely installed, and is anti-
Only the discomfort really up to the mark that may cause wearer, the nose bar are preferably made of soft rubber or plastics.It is horizontal to keep fastening close
The oblique L-shaped structure that bar 4-2 and brace 4-1 is constituted is in 45 °~90 ° angles, i.e. the angles α in Fig. 1 are between 45 °~90 ° angles
As shown in Fig. 2, the hood pad 3 includes upper ring 3-1 and the lower ring 3-2 being connected as one with upper ring 3-1, upper ring 3-1 and cover
The lower end of body 2 connects, and the diameter of upper ring 3-1 is less than the diameter of lower ring 3-2.The hood pad 3 is the silicon made of silica gel material
Rubber cushion.It is not difficult to find out from figure, upper ring 3-1 and lower ring 3-2 constitutes an annulus, and the facial contact with wearer is one
Complete anchor ring, contact area is big, can more improve the comfort level of wearer.
The mask of the present invention when in use, can be first according to the patient's bodily form for wearing mask, up and down adjustment cutting ferrule 5;It is over again
Mask is directed to the snout of patient, then light pressure, then the cross bar 4-2 of fastener is buckled in the lower jaw part of patient, that is, completed.This
The mask of structure can be kept fixed and reinforce air-tight state for a long time.
It these are only and illustrate embodiments of the present invention, be not intended to restrict the invention, for those skilled in the art
For, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
