Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 and 2, described one can suction sputum laryngeal mask, including connecting the respiration channel 1 for ventilating with breathing pipeline and patient's glottis mouth, for aspirating the attraction channel 2 of sputum or the gastric juice that backflows and the relief passage 3 for attraction channel 2 negative pressure pressure is adjusted.Described respiration channel 1 includes the laryngeal mask cover body 11 of airtight connection successively, breather 12 and respirator interface 13.Described laryngeal mask cover body 11 is arranged to the relief pipe 21 to gastral cavity decompression foremost, and the head end suction port 22 of described attraction channel 2 is layer adjacent to relief pipe 21 exit, exports with relief pipe 21 and does not connect.The tail end of described attraction channel 2 attracts interface 23 to be arranged at outside oral cavity.The head end of described attraction channel 2 or attraction channel 2 is contained in the relief chamber 31 of relief passage 3.The relief chamber 31 of described relief passage 3 is arranging some vents 32 away from the offside cavity wall bottom laryngeal mask wall cover body 11.
Respiration channel 1 is the apokoinou construction of current laryngeal mask, and laryngeal mask is put outside patient's glottis by laryngeal mask cover body 11 cover of respiration channel 1, is connected with anesthetic machine or respirator by breather 12 and respirator interface 13, provides Breathing Suppotion for patient.No longer respiration channel 1 is done further specific descriptions herein.
This utility model arranges relief pipe 21 at the described most head end of laryngeal mask cover body 11, inserts tube head end position in use with the stomach tube of LMA laryngeal mask identical, be all insert patient's esophageal aperture portion.The difference is that, the stomach tube of LMA is inserted Guan Weiyi closed conduit and is opened on patient's extrabuccal respiration channel 1 top, inserts pipe by stomach tube and can only insert stomach tube or insert sputum aspirator tube to gastral cavity decompression, and there is no other use for it.And relief pipe 21 length is shorter in this utility model, it is only 5mm-20mm, namely forms the outlet of relief pipe 21.In use, patient's esophageal aperture portion largely or entirely inserted by described relief pipe 21.When stomach cavity pressure is higher, liquid or gas can be discharged by relief pipe 21 through esophagus.
The head end suction port 22 of attraction channel 2 is layer adjacent to relief pipe 21 exit, and tail end attraction interface 23 is arranged at respiration channel 2 and is positioned at extrabuccal breather 12 position.The liquid of gastral cavity eliminating or gas are after esophagus and relief pipe 21 are discharged, and the head end suction port 22 that can pass through attraction channel 2 enter attraction channel 2 inner chamber, attract interface 23 to excrete eventually through tail end.Certainly, operation during concrete discharge is: attracts interface 23 to insert attraction channel 2 inner chamber by tail end sputum aspirator tube and stretches out head end suction port 22, discharged through sputum aspirator tube by liquid under the effect of suction pump negative pressure.
Attraction channel 2 is contained in the relief chamber 31 of relief passage 3, and the back side wall that relief passage 3 is fully contacted away from respiration channel 1 and palate mucosa in oral cavity arranges some vents 32.During use, described can suction sputum laryngeal mask patient oral cavity, the head end suction port 22 of described attraction channel 2 is positioned at the lowest point of relief chamber 31, relief chamber 31 is vertical, in oral cavity, the sputum of glandular secretion can enter relief chamber 31 through some vents 32 of relief passage 3 under gravity, and it is collected at the lowest point of relief chamber 31, the i.e. position of the head end suction port 22 of attraction channel 2.When needing to clear up, directly attract interface 23 to connect adapter for suction unit at the tail end of attraction channel 2, or attract interface 23 to insert sputum aspirator tube cleaning by the tail end of attraction channel 2.
Now, the meaning that arranges of described relief passage 3 is in that to make the dorsal part of laryngeal mask cover body 11 and the mucosa of oral cavity palate to form certain gap, make to obtain in the oral cavity in liquid can through gap, the inner chamber of some vents 32 and relief passage 3 accumulate to the head end suction port 22 of attraction channel 2.When the tail end of attraction channel 2 attracts interface 23 to connect negative-pressure suction pipeline, negative pressure is conducted to head end suction port 22 through attraction channel 2, is transmitted to each vent 32 through the relief chamber 31 of relief passage 3 further.Under suction function, in oral cavity, sputum everywhere enters relief chamber 31 through each vent 32, accelerates to be transmitted to head end suction port 22, and then is attracted interface 23 to discharge through attraction channel 2 by tail end.
But the meaning that relief passage 3 is arranged is not limited to be easy to sputum and gathers cleaning, prior effect is to regulate attraction channel 2 head end suction port 22 intensity of negative pressure pressure when clearing up sputum, it is to avoid negative pressure pressure is excessive to cause damage to tender and lovely oral cavity palate mucosa.
Its regulate the negative pressure intensity of pressure principle be: when intraoral sputum or the gastric juice that backflows is more still do not have cleaned time, liquid is detained in the relief chamber 31 of relief passage 3, in relief passage 3 bottom chamber, in relief pipe 21 or head end suction port 22 place of attraction channel 2, when attraction channel 2 directly being attracted or attract cleaning liquid by sputum aspirator tube, liquid secretion thing is discharged under suction function.Meanwhile, the sputum that part is detained in relief chamber 31 is cleaned, and it is unobstructed that the relief chamber 31 of relief passage 3 becomes, and the gas outside laryngeal mask enters in relief chamber 31 through each vent 32, and then enters in attraction channel 2 through head end suction port 22.Now, although the head end suction port 22 of attraction channel 2 there is no sputum, but owing to the relief chamber 31 of relief passage 3 is unblocked, large quantity of air enters attraction channel 2 through the relief chamber 31 of relief passage 3, the negative pressure of the head end suction port 22 of attraction channel 2 reduces, will not being tightly adsorbed in the mucosa of oral cavity palate, described can cause damage without to the mucosa of oral cavity palate by suction sputum laryngeal mask even if extracting under the situation that attraction channel 2 tail end attracts interface 23 to connect negative-pressure suction pipeline.
As mentioned above, reach by attraction channel 2 head end is encompassed the relief passage 3 being provided with some vents 32: when very moment intracavity is by more secretions, the vent 32 of relief passage 3 makes relief chamber 31 blocked because secretions flows into, the negative pressure of attraction channel 2 can not be flowed into by air and reduce, the negative pressure of attraction channel 2 can reach the maximum of vacuum suction path, under this negative pressure, liquid secretion thing is discharged through attraction channel 2 rapidly；When secretions part is discharged, owing to the secretions in the part reduced pressure hole 32 of relief passage 3 is eliminated, relief chamber 31 stopping state is made to take a turn for the better to some extent, air enters relief passage 3 with suitable speed through part reduced pressure hole 32, the negative pressure of attraction channel 2 reduces to some extent, but still can the secretions of residual in relief passage 3 be cleared up；After secretions drains, the secretions of all vents 32 is all eliminated, the relief chamber 31 of relief passage 3 is unblocked, large quantity of air enters attraction channel 2 through the relief chamber 31 of relief passage 3, the negative pressure of the head end suction port 22 of attraction channel 2 is reduced to the lowest limit, forms a suck and does not attract or the purpose of more weak attraction oral mucosa.Be finally reached oral secretion more time attraction channel 2 attract oral secretion, when oral secretion is cleaned out, attraction channel 2 only suck does not attract the purpose of oral mucosa.
As shown in Figure 1, Figure 2, shown in Fig. 4, Fig. 5, Fig. 6 and Fig. 7, described attraction channel 2 and relief passage 3 are arranged at respiration channel 1 laryngeal mask cover body 11 bottom side.Described can suction sputum laryngeal mask for Breathing Suppotion time, the opening of laryngeal mask cover body 11 shrouds at glottis mouth, and sputum effectively to be cleared up by described attraction channel 2, and its head end suction port 22 need to be arranged on intraoral lowest point, i.e. position foremost bottom laryngeal mask cover body 11.Putting before this, will make attraction channel 2 arrangement optimization, attract unobstructed, namely optimum position is arranged on the respiration channel 1 bottom side away from laryngeal mask cover body 11 opening.And relief passage 3 preferably encompasses attraction channel 2 and arranges, the respiration channel 1 dorsal part away from laryngeal mask cover body 11 opening should be arranged side by side in attraction channel 2.
As shown in Fig. 4, Fig. 5, Fig. 6 and Fig. 7, relief passage 3 transverse section is that class is oblate, and described attraction channel 2 is connected with the sidewall of relief passage 3.In Fig. 4 and Fig. 5, described attraction channel 2 is connected with the front and rear wall median line of relief passage 3, relief chamber 31 transverse section of described relief passage 3 is attracted passage 2 and is divided into two symmetrical class crescent relief chambers 31, and described attraction channel 2 is fixed in relief passage 3 by safe.Simultaneously, relief passage 3 is played a supporting role by described attraction channel 2, the relief chamber 31 making relief passage 3 is divided into two symmetrical class crescent, deformation it is not easy under the pressure effect of oral mucosa, decrease the movement of the laryngeal mask cover body 11 caused therefrom, reduce further laryngeal mask cover body 11 and leak gas when mechanical ventilation Probability.
In Fig. 6 and Fig. 7, attraction channel 2 closes on the sidewall median line of laryngeal mask cover body 11 side and is connected with relief passage 3, and relief chamber 31 transverse section of described relief passage 3 is attracted passage 2 and is reduced to a meniscate relief chamber 31 of symmetrical class.In this embodiment, when relief passage 3 receives bigger pressure, the back side wall that relief passage 3 dissociates with attraction channel 2 is likely to deformation, abuts on the tube wall of attraction channel 2.But the advantage of this embodiment is that on relief passage 3 lateral wall, area for arranging vent 32 increases, it is possible to more comprehensively to oral cavity liquid secretion thing cleaning everywhere.
Attraction channel 2 can also encompass in the relief chamber 31 being arranged on relief passage 3, is not connected to the inner side cavity wall of relief passage 3.Its specifically used effect and above two scheme there is no dramatically different, simply a kind of viable solution.
Additionally, it is noted that: attraction channel 2 is necessarily placed in the relief chamber 31 of relief passage 3 except head end suction port 22, the suction pipeline of attraction channel 2 and tail end attract interface 23 can be arranged on outside relief passage 3, and being even arranged on also is feasible in respiration channel 1.Simply from best ventilatory effect and optimal appearance, attraction channel 2 is preferably provided in the relief chamber 31 of relief passage 3.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the transverse section of the suction cavity of described attraction channel 2 and the inner chamber of relief pipe 21 includes similar round, the suction cavity of described attraction channel 2 is round and smooth with the central axis of the inner chamber of relief pipe 21 to be connected, when suction cavity along attraction channel 2 inserts stomach tube, stomach tube can enter the inner chamber of relief pipe 21 smoothly.
The inner chamber of attraction channel 2 and relief pipe 21 arranges similar round, it is simple to sputum aspirator tube insert in tube chamber to be collected in attraction channel 2 and relief pipe 21 backflow gastric juice or saliva is cleared up.Certainly, the inner chamber of attraction channel 2 and relief pipe 21 can also be arranged to other shapes, but its tract size need to be enough to hold sputum aspirator tube inserts.
Be connected round and smooth with the central axis of the inner chamber of relief pipe 21 of the suction cavity of attraction channel 2 inserts the inner chamber of suction cavity and the relief pipe 21 drawing passage 2 when being easy to sputum aspirator tube cleaning sputum, also allow for stomach tube and insert the enforcement gastral cavity decompression of Stomach in Patients intracavity.If the central axis of attraction channel 2 and the inner chamber of relief pipe 21 is not on a slur, when stomach tube or sputum aspirator tube are inserted, inevitable it is obstructed between the head end of passage 2 and relief pipe 21 tail end drawing, result of use is caused ill effect.
When being embodied as, the suction cavity of described attraction channel 2 and the inner chamber of relief pipe 21 may be arranged as the tract connected as one, but arrange STH at the joining place of described relief pipe 21 and attraction channel 2 and form the head end suction port 22 of described attraction channel 2.This is the embodiment of a kind of optimization, the suction cavity of attraction channel 2 and the inner chamber of relief pipe 21 is made to form one tract in some sense, technique is more succinct, now, attraction channel 2 must arrange STH at attraction channel 2 and relief pipe 21 joining place from different being in that somewhat like but important with the gastral cavity relief pipe of LMA on the associating pipeline configuration of relief pipe 21.The STH herein arranged functionally is equivalent to the head end suction port 22 of attraction channel 2.During cleaning liquid secretions, intraoral liquid enters in the relief chamber 31 of relief passage 3 through vent 32, and then arranges STH entrance attraction channel 2 via attraction channel 2 and relief pipe 21 joining place, is finally discharged under suction function.
Some vents 32 area of relief chamber 31 is all higher than the suction cavity area of section of attraction channel 2.Sufficiently large vent 32 area is arranged, and makes relief chamber 31 can guarantee that the effect of easing stress to attraction channel 2, it is to avoid vent 32 is adsorbed in oral mucosa and damages when extracting laryngeal mask.
