Description
Technical field
This utility model relates to for the air flue that gas is flowed to the user and/or carries the patient interface of gas from user's air flue.
Background technology
Under many circumstances, need or wish respiratory air flow non-invasively is delivered to patient's air flue, namely conduit need not be inserted patient's air flue or in operating mode endotracheal tube is inserted in its esophagus.For example, be known that adopting known is that the technology of noinvasive ventilation (non-invasive ventilation) is ventilated for the patient.It is also known that, carry persistence Positive Airway Pressure (CPAP) that the breath cycle with the patient changes or variable airway pressure with the imbalance for the treatment of medical science, for example sleep apnea syndrome, the especially obstructive sleep disease (OSA) of suffocating.
Noinvasive ventilation and pressure supporting treatment relate at patient's face places the patient interface device that comprises mask part.Mask part can be the full facepiece mask of nose cup, the nose pillow/nose pad with the nasal obstruction in the patient's nasal openings of being contained in that covers patient's nose, the nose/mask that covers nose and oral area or covering patient's face without limits.The patient interface device is between ventilator or pressure support device and patient's air flue, thereby respiratory air flow flows to patient's air flue from pressure/stream generation apparatus.
Such device usually by have on one or more head that is assemblied in the patient/headstock (headgear) of on every side band remains on patient's the face.
Fig. 1 demonstrates for the canonical system that respiratory therapy is provided to the patient.This system will be called as " patient interface system " in description and claims.
This system 2 comprises Pressure generator 4, the conveyance conduit 16 that connects with elbow adapter 18 and patient interface device 10.Pressure generator 4 is configured for producing respiratory air flow and can unrestrictedly comprises ventilator, constant voltage supportive device (for example persistence positive airway pressure devices or CPAP device), variable pressure device and automatic titration pressure supportive device.
The problem of the face shield of the type is, can rein in out straight line for realizing near the patient canthus against the required headstock force vector of the firm and stable sealing of patient's face, and this can uncomfortable and dispersion patient attention.
For fear of this situation occurring, be well known that to comprise that forehead support is to be dispersed in required power on the bigger zone.Like this, the additional pad support balance on forehead be applied to power around nose or the snout by face shield.
In order to make face shield all to realize comfortable cooperation at various users, forehead support needs and can partly regulate with respect to nose/mask.In a kind of known design, this is by the end at the arm that is pivotally connected to main nose/mask part forehead support to be set to realize.This makes forehead support to pivot towards forehead and away from forehead ground, so that different users is realized different relative localizations.
Another kind of known design has the forehead support that is mounted to linear movement between advanced position and extended position.Adopt the rotation adjusting knob to come to regulate by hickey the linear position of forehead support.
Describe this known design in US2010/0000542 in detail, the document is merged in thus by reference.
The problem of this design is that hickey can produce noise at conditioning period and when finishing adjusting.The accuracy of mesh between thread spindle can produce the noise of click clatter, and gives the ratchet type joint that knob presets the position and can produce thump noise.Since close with wearer's face (and so ear), so these noises can troublesome.In addition, under the situation that may use the face shield that is used for the treatment of sleep-apnea, these noises are especially undesirable.
The utility model content
The purpose of this utility model is in order to overcome at least one shortcoming of above-mentioned prior art.
According to this utility model, a kind of patient interface system is provided, it is characterized in that comprise: the patient interface device is used for being communicated with patient's nose or snout; And forehead support, described forehead support connects with described patient interface device and has a support pad; Wherein, described forehead support comprises governor motion, described governor motion comprises the knob with threaded drive shaft and the screw thread driven shaft that connects and connect with described support pad with the driving shaft of described knob, and the rotation of described knob makes described driven shaft linear movement and also make described support pad linear movement thus; Described forehead support also comprises denoising device (sound damping means), is used for alleviating the sound that produces when having relative motion between described driving shaft and described driven shaft.
Driving shaft can comprise center core and screw thread on every side (being screw rod), and driven shaft then comprises outside cylinder oblique crank Z and female thread (being screwed hole).
In first system, denoising device comprises the elastic coating that is positioned on screw thread (outside) driving shaft.In second system, denoising device is included in the elastic coating on screw thread (inside) driven shaft.In both cases, this has reduced the noise of when these axles relative to each other rotate (at conditioning period), and it also helps when finishing adjusting two axles to be remained on fixing relative position place (having avoided occurring click thus).Elastic coating can be rubber coating.
In the 3rd system, denoising device comprises at least one added thread that is positioned on the threaded drive shaft and at least one the corresponding added thread that is positioned on the screw thread driven shaft, thereby driving shaft passes through at least two parallel thread connection with driven shaft.This provides stronger maintenance between these, relative motion occurs and limit clearance at conditioning period after regulating preventing, has reduced the noise that click is rattled away thus.
In the Quaternary system system, denoising device comprises for the elastic component with respect to driven shaft linear bias driving shaft.This has reduced the noise that click is rattled away again by keeping fixing more relative position.
Elastic component can be to press the end of center core and be installed in spring in the outside cylinder oblique crank Z.Like this, spring is installed in thread spindle device inside.Alternatively, elastic component can be spring or the rubber components around the base portion of the handle of knob.
Knob can comprise the stop position that is limited by the interaction between tab and recess, wherein has a plurality of tabs and/or a plurality of recess to limit a plurality of stop positions of knob, and wherein tab is coated with elastomeric material.
This coating makes in the adjusting click that presets between the knob position lighter.Recess alternatively (perhaps same) is coated with elastomeric material.
According to patient interface system of the present utility model make patient interface adjusting and/or use quieter, thereby the uncomfortable property that the patient is caused is lighter.
