Abstract
The trachea cannula of the present invention, is related to the technical field more particularly to trachea cannula of medical equipment.In order to solve the problems, such as that existing trachea cannula easily causes to damage to the tracheae of patient in use, trachea cannula provided by the invention, including：Cuff, which is characterized in that it is recessed stupefied axially to open up one or more at the middle part of the cuff.Advantageous effect：The trachea cannula of the present invention is contacted by effectively preventing " cuff " side wall to the side wall setting " axial notch " of " cuff " with the wholecircle circumferential surface of tracheae, especially to the tracheae of different parts, its " cuff " is after to inner surface of trachea tentatively support, " tracheae " shape can be also effectively matched to improve the property on probation of product by the local deformation of groove.It can especially be accommodated on tracheal wall remaining " tamper " by groove, " tamper " " cuff " will not be expressed between inner surface of trachea during support, to cause to damage to tracheal wall due to squeezing.
Description
Technical field
This hair is invented and the technical field more particularly to trachea cannula of medical equipment.
Background technology
During the Emergency Assistance of urgent patient, in order to avoid tamper causes embolism to be given birth to crisis patient's trachea
Life, to often carry out " airway open " to patient by trachea cannula.Existing trachea cannula is intubated to patient
Afterwards, it needs to be supported tracheal wall by " cuff ", consequently facilitating the smooth opening of air flue.But in the gas replenishment process of cuff
In, if inflation is improper, it can cause damages to the inside of tracheae, to be impacted for subsequent treatment and correct diagnosis.Thus
It is found that since existing " cuff " needs full side to be contacted with the inner wall of tracheae, if excessively being inflated to " cuff ",
Local damage can be caused to inner surface of trachea, to influence subsequent diagnosis and treatment.
Invention content
In order to solve the problems, such as that existing trachea cannula easily causes damage, the present invention to the tracheae of patient in use
The trachea cannula of offer, including：Cuff, which is characterized in that it is recessed stupefied axially to open up one or more at the middle part of the cuff.
In a preferred embodiment, the recessed stupefied depth is 1~1.2mm.
In a preferred embodiment, it is arc to be located at recessed stupefied bottom at the cuff maximum gauge.
In a preferred embodiment, the recessed stupefied circumferencial direction along the cuff is distributed.
In a preferred embodiment, the recessed stupefied quantity is 2,4 or 6.
In a preferred embodiment, further include；Air charging system, aeration control device and baroceptor；It is described
Baroceptor is set in the loading line of the air charging system, is given and is adopted to the current pressure values in the loading line
Collection, induction pressure output end are connect with the input terminal of the aeration control device, the output end of the aeration control device and institute
State the ventilating control end connection of air charging system；When the current pressure values received be more than it is local prestore setting value when, then to
The output end, which is sent, stops inflation information, and the air charging system stops inflation according to the stopping inflation information received.
In a preferred embodiment, further include：Instruction device；The output end of the aeration control device with it is described
Instruction device connects；After sending stopping inflation information, then the instruction device is driven to send out instruction information.
In a preferred embodiment, the instruction device includes：Buzzer or indicator light.
As shown in the above, the beneficial effects of the present invention are trachea cannula of the invention passes through the side to " cuff "
Wall setting " axial notch " effectively prevents " cuff " side wall and is contacted with the wholecircle circumferential surface of tracheae, especially to the gas of different parts
Pipe, " cuff " can also carry out " tracheae " shape by the local deformation of groove after to inner surface of trachea tentatively support
It is effectively matched.To improve the property on probation of product.It can especially be accommodated by groove on tracheal wall remaining " tamper ",
" tamper " will not be expressed to " cuff " between inner surface of trachea during support, to be caused to tracheal wall due to squeezing
Damage.
