Description

A kind of medical respiratory masks

Technical field

This utility model relates to technical field of medical instruments, particularly a kind of medical respiratory masks.

Background technology

At present, medical respiratory masks has been widely used in clinical medicine, especially in assisting patients breathing, obtains more wide application.But along with the use in clinical, medical respiratory masks has also engendered inadaptability.Medical respiratory masks needs laminating patient facial region skin to use usually, and therefore profile and the patient facial region of medical respiratory masks need fit tight, otherwise will cause leaking gas, and do not reach expection therapeutic effect; In addition, owing to being fitted in patient facial region for a long time, also often there will be the dermonecrotic situation of contact surface of patient facial region.

Therefore how to improve the profile of medical respiratory masks, strengthen sealing, reduce necrosis rate and become one of current problem demanding prompt solution.

Therefore existingly have much room for improvement and develop.

Utility model content

The technical problems to be solved in the utility model is to provide the sealing strengthening breathing mask and user face, and reduces the medical respiratory masks of contact surface cutaneous necrosis rate.

Technical solution of the present utility model is: a kind of medical respiratory masks, comprise there is front surface and rear surface and can cover user face framework, be provided with airway and exhaustor over the front surface, this rear surface offers containing cavity, and this airway and exhaustor are all communicated with this containing cavity; The pad that a circle is made up of elastic material is provided with in containing cavity edge; Airway periphery is arranged with and has four head bracelets for the first ring set of horizontal fixed visors with have at least one headband and buckle the second ring set for longitudinal fixed visors, the first ring set and the second ring set all can horizontally rotate around airway; Described pad is the pad that memory foam is made, and described pad one side is fitted with described containing cavity rim seal, and the face of another side and user is fitted, and four head bracelets of described first ring set are uniformly distributed along described first ring set circumferencial direction.

Framework can cover user face, and the airway that framework front surface is arranged and exhaustor can be convenient to suck user oxygen intake, give off carbon dioxide; The nose mouth of user is placed in containing cavity, and containing cavity edge arranges the pad of a ring elastic material composition, effectively can strengthen the sealing of framework rear surface and user face, because pad is that elastic material is made therefore effectively can reduce contact surface cutaneous necrosis rate; Airway periphery is arranged with first ring set with four head bracelets and there is the second ring set that at least one headband buckles; Four head bracelets of the first ring set can make breathing mask laterally fixing; Second ring set can make breathing mask longitudinally fixing; And the first/the second ring set is and is set on airway periphery, can rotate around airway, the convenient breathing mask of adjustment is in real time in the position of user face.Pad selects memory foam to make, and has very high plasticity, and the patient for facial deformity is applicable equally, especially face is had to patient's better tightness of stomach tube.

The side undulate that described pad contacts with user forehead.Prevent oxygen in airway from pad edge leakage further, increase sealing.

Also comprise and buckle with described headband the frenulum be equipped with.

Described exhaustor is sealed by cork.Need then cork to be opened when using, prevent dust impurity from entering exhaustor in not used time with cork sealing.

The beneficial effects of the utility model:

Strengthen the sealing of breathing mask and user face, and reduce contact surface cutaneous necrosis rate, adjust breathing mask in real time in the position of user face, be especially suitable for the patient that facial deformity and face have stomach tube.

Detailed description of the invention

Embodiment:

Consult Fig. 1 Fig. 2, a kind of medical respiratory masks, comprise there is front surface 11 and rear surface 12 and can cover user face framework 1, framework 1 is made up of Merlon, polyester, polyamide, polyether-ether-ketone or ABS; This front surface 11 is provided with airway 111 and exhaustor 112, and airway 11 and breathing mask can pivot joints or affixed, and airway 111 has connector 1110 and is connected with external air source; Exhaustor 112 is sealed by cork, prevents impurity dust from entering, opens cork when needing.This rear surface 12 offers containing cavity 121, and this containing cavity 121 is that nose room and mouth room are combined into the cavity with human face nose and mouth 3D shape; This airway 111 and exhaustor 112 are all communicated with this containing cavity 121, and realize the eupnea process of user, source of the gas enters user from airway 111, and the carbon dioxide that user is discharged is discharged from exhaustor; The pad 2 that a circle is made up of elastic material is provided with in containing cavity 121 edge; The material of pad 2 preferably has the memory foam compared with high plasticity; Pad 2 one side is fitted with containing cavity 121 rim seal, and the face of another side and user is fitted; Further, the side undulate that pad 2 contacts with user forehead, makes pad 2 and user forehead fit more tight.Increase the face seal of breathing mask and user, prevent gas leakage.

Airway 111 periphery is arranged with first ring set 3 with four head bracelets 10 and there is the second ring set 4 that at least one headband buckles 10.First ring set 3 and the second ring set 4 all can horizontally rotate around airway 111.Certain breathing mask of the present utility model also comprises buckles 10 frenulums be equipped with (not shown) with headband, frenulum material is for having elastic rubber, arrange multiple aperture along frenulum length direction, four head bracelets 10 of the first ring set 3 are uniformly distributed along the first ring set 3 circumferencial direction; The size that headband buckles 10 is less than the hole diameter of frenulum, the convenient tightness regulating breathing mask and user.Four head bracelets 10 of the first ring set 3 are connected rear laterally fixing breathing mask with frenulum, the second ring set 4 is connected longitudinally fixing breathing mask with frenulum.First ring set 3 and the second ring set 4 are set on airway and then can rotate around airway 111, can adjust the position of breathing mask and user face in real time, prevent gas leakage further.

Above-listed detailed description is illustrating for this utility model possible embodiments, and this embodiment is also not used to limit the scope of the claims of the present utility model, does not allly depart from the equivalence that this utility model does and implements or change, and all should be contained in the scope of the claims of this case.
