A kind of general multifunctional respiratorTechnical field
The present invention relates to a kind of general multifunctional respirator, belongs to oral cavity diagnosis, medical aid, Aero-Space, chemical defenceEquipment, diving, fire-fighting, labour protection, health care and daily living article field.
Background technology
At present, the nose cup of existing various uses, mouth mask, oxygen mask even breathing mask, space suit, isolation clothes etc setIn meter structure and form, have excessively simple and lose application performance, some designs are loaded down with trivial details to cause that manufacturing operation is more, costHeight, in application, also generally existing patency is inadequate, and aeration resistance is big, makes us having sense of feeling oppressed, and entrained gas are substantially, sealingProperty, wearing comfort and fastness are poor, are not easy to that disinfecting, design function and purposes are single, flexibly and easily can not be applied toVarious occasions, some designs show in actual applications unreasonable, such as in rescue or hospital surgical to patient with oxygen maskAir inlet and exhalation vents or connection conduit positions inconvenient, the also operation and nursing to surgical procedure is made troubles.
Content of the invention
The purpose of the present invention is a kind of general multifunctional respirator of design, ergonomically, is set using integrationCount and take into account the comfortableness and rationality in application that wears, while atm number smooth breathing is guaranteed, with setting for many gas channelsMeter form, may be selected multichannel gas circuit conversion combination, and is provided with one-way membrane valve, prevent and reduce expiratory air mixed with suction gasGas phenomenon, has seal and non-deformability in structure, also effectively inspiration gas and expiratory air can be hedged off from the outer world, preventExpiratory air is entered in air spreads, and prevents breath transmission, and is not limited solely to single application scenario, can not only be easily and flexiblyIt is used as nose cup, mouth mask, oxygen mask, or even breathing mask, isolation clothes etc. can be connected, rescues so as to reach adaptation oral cavity diagnosis, medical treatmentThe purpose of design of shield, Aero-Space, military chemical defence, diving, fire-fighting, labour protection, health care and daily life field.
Concrete technical scheme of the present invention is；Design breathing cover body is the integration knot for meeting ergonomicsStructure, overall spatially triangle, enclosed hood on nose or on muzzle, fitted with the facial corresponding site of people by periphery；BreathingCover body is designed with the left and right breather pipe being interconnected of top breather pipe and bottom on the whole, and in the respirator body face left and rightOn breather pipe, appropriate location opens up side opening respectively, to increase many gas circuit approach and expand air flux；The left and right of breathing cover body leads toTracheae carries out that sealing is bonding or sealing is patched respectively with the outside left and right adapter for accessing, and outside left and right adapter can be with side openingCecum adapter so as to side opening is corresponding with the side opening opened up on left and right breather pipe in respirator body, it is also possible to according to differenceGas circuit application combining form, use the through type generally without side opening instead and take over；Breather pipe connection in left and right in respirator bodyCentral part is provided with the frame slot type of one-way membrane valve and is fitted together to mouth；One-way membrane valve is the film valve of unidirectional outside exhalation, by valve film and valve filmSupport is constituted, and the frame slot type that valve membrane support is with face central part in respirator body is opened up is fitted together to the corresponding framework of mouth, and bandThere are the valve film support column of the longitudinal direction of consubstantiality, the top of valve film to fix the top edge being pasted onto outside valve membrane support, valve film is usualIt is that elastic fit is closed in film valve support under state, valve film can only be opened towards the direction for outwards breathing out, the one-way membrane valveIt is close that the frame slot type opened up by the central part of the left and right breather pipe connection in face in the embedded respirator body of valve membrane support is fitted together to mouthClose and bond together；Bottom outlet opening grid is opened up in the corresponding breathing cover body bottom of one-way membrane valve, is that list is passed through in expiratory airTo the outlet of the outside exhalation of film valve, when being combined from different gas circuit applications, can not open up at this outlet opening grid orBlocked, suction gas and expiratory air is made all through pipeline liquid injecting device, prevent expiratory air to be diffused into unhygienic in air or causeInfect, also dependent on application scenario, small hole is opened up herein as acoustic aperture or dew drip hole；Breathing cover body lower limb is designed withSealing edge, to strengthen the seal of application comfortableness and laminating；In respirator body, the central part of wall has and breathing cover body oneVertical structure reinforcement, to strengthen overall construction intensity and non-deformability, also increase the firmness and closed during applicationProperty；The sealing strip of design inner peripheral wall is the flexible sealing strip for having proper width and suitable thickness for being pasted onto inner rim, with closeThe laminating degree and comfort level of the facial contact of envelope respirator periphery and increase and people, and, respirator periphery can be with protectionThe peripheral accessory of glasses, protective face mask, isolation clothes and protective garment etc does integrated seamless connection；The external arm both sides of respiratorAppropriate location is provided with wearing rope link during application, is worn with facilitating, and further enhances overall fastness and seal；In additionAlso devise and matched from different gas circuit application combinations for blocking the standby pipe close of each mouth of pipe, pipe cap and filter cap,Filter cap therein has filtration square and embedded screen pack and screen pack trim ring, can be held in outside left and right connection pipe opening, a left sideOn the right ventilation mouth of pipe or the top ventilation mouth of pipe, filter in order to the air to sucking.
The invention has the beneficial effects as follows meet the Three-dimensional triangle shape of the integral structure of ergonomics, compact conformation,Multi-functional, highly versatile need to only do the scaling of a little sizes, can just cover on nose or on muzzle, and periphery is fitted with face, closedGood, the resistance to deformation of property, wearing mode is various and Energy and comfort；The design of wherein one-way membrane valve, prevents and reduces expiratory air and suctionEnter the entrained gas of gas；Rationally, air flux is big for the design science of many gas circuits, breathes smooth；Agent structure globality is strong, can be onceShaping, production technology are easier, low cost, can be required according to different application scenarios, select multiple gas circuit combinations, can also be externalThe Medical Devices such as lung ventilator；If making suction gas and expiratory air all through breather adapter system, can effectively be hedged off from the outer world, preventGet into the air diffusion, prevents breath transmission, also can be used as the daily health caring application of air filtration and haze；Can be convenient, flexibleGround is used as nose cup, mouth mask, oxygen mask, or even can connect breathing mask, isolation clothes etc., can be widely applied to oral cavity diagnosis, medical treatmentRescue, Aero-Space, military chemical defence, diving, fire-fighting, labour protection, health care and daily life field.
