Detailed description of the invention
Laryngeal mask wide variety in prior art, but these laryngeal masks generally fail to reserve as tracheoscopic passage, make patient after inserting laryngeal mask, are difficult to the foreign body removed by tracheascope in trachea.The size of laryngeal mask should adapt to patient throat size, but what have that any can be clear and definite is exactly that, except the air bag ring of trunnion front end, the volume shared by trunnion rear end is less, is more beneficial to operation.And most important function sets up breathing path for patient in trunnion, the space fixed therefore is needed to leave passage for.During passage design be consider fully meet the condition of patient respiratory under the full-size that designs, traditional spiracle size is fixing, for closed circular hole, but the space in fact in spiracle is also underutilized, because in most of the cases do not need so large passage to breathe, this also just provides sufficient condition for the utilization of spiracle.
Mentality of designing of the present utility model is, when needs utilize tracheascope, takies the space of part spiracle, makes the path of travel providing tracheascope when not affecting eupnea, to make full use of space, reduces the volume of whole laryngeal mask.
A kind of can the laryngeal mask of air supply pipe spectroscopy, comprise set casing 10, set casing 10 front end is provided with the joint face 12 of concave shape, the passage 6 leading to joint face 12 is provided with in set casing 10, edge is provided with air bag ring 3 to joint face 12, be provided with the handle hole 8 with the equidirectional extension of passage 6 in described set casing 10, intercepted by elastic barrier film 9 between passage 6 and handle hole 8.
The basic structure of laryngeal mask comprises air bag ring 3, joint face 12 and set casing 10, is wherein provided with the passage 6 leading to joint face 12 in set casing 10.Joint face 12 is concave shape, can be similar to and be interpreted as funnel structure, and air bag ring 3 can be thought circumferentially to arrange at joint face 12.In fact, in order to adapt with the physiological structure of human body throat, the monnolithic case of air bag ring 3 is the slightly narrow ellipticity in one end, as shown in Figure 2.Air bag ring 3 is mainly played a supporting role, soft structures, connects inflation inlet 1, inflate after inserting throat by gas tube 2, and air bag ring 3 is heaved.
The passage 6 arranged in set casing 10 leads to front end from the end of set casing 10 always and passes joint face 12.That closed structure is different from passage 6 in traditional laryngeal mask, in this utility model, passage 6 is non-closed, and the handle hole 8 with the equidirectional extension of passage 6 is provided with in the adjacent side of passage 6, the aperture of handle hole 8 is little compared with passage 6, and is intercepted by the barrier film 9 that one deck is soft between two holes.Soft barrier film 9 is airtight, has good elasticity, makes as adopted elastomeric material.Handle hole 8 is the passages provided of advancing for tracheascope, and tracheascope extend into after in handle hole 8, struts barrier film 9, pushes up barrier film 9 in passage 6, is equivalent to tracheascope and occupies space in a part of passage 6, as shown in Figure 3, Figure 4.But general tracheascope diameter is little far beyond passage 6, and handle hole 8 is already for which providing a part of space, although therefore tracheascope occupies the space of a part of passage 6, but remaining space still can maintain patient's eupnea in passage 6, laryngeal mask is so just made to take full advantage of the space of passage 6 when needed.
The lateral cross section of passage 6 is C shape, and the lateral cross section of handle hole 8 is one section of circular arc.
As shown in Figure 2, the lateral cross section of passage 6 is c-shaped, and lateral cross section refers to the face perpendicular to through hole axial line.If passage 6 to be regarded as a pipe, be so equivalent to be vertically arranged with strip shape gob on pipe, with described barrier film 9 on strip shape gob.The lateral cross section of handle hole 8 is one section of circular arc, and the opening of this section of circular arc is towards passage 6 direction, and the two junction arranges barrier film 9.Barrier film 9 shrinks in its natural state in handle hole 8, and now passage 6 can keep a relatively complete passage, and its lateral cross section can be similar to regards a circle as, can provide space fully for breathing; And after implantation tracheascope, barrier film 9 is pushed in passage 6 by tracheascope, temporarily takies a part of space of passage 6, finishes using after extracting tracheascope, returns to original position at elastic effect lower diaphragm plate 9.
For the ease of operation, the end of set casing 10 is provided with fixing head 4, fixing head 4 is provided with one section with the trachea socket 5 of passage 6 company of passing through.
Fixing head 4 can be stuck in outside patient's mouth after laryngeal mask, is also convenient to fetch simultaneously.Trachea socket 5 is connected with passage 6, and trachea socket 5 directly connects breathing apparatus.
Fixing head 4 is provided with the through hole running through fixing head 4, one end of through hole is connected with handle hole 8, and the through hole other end is connected with an elastic secondary socket 7.
Fixing head 4 arranges a through hole, and through hole two ends are handle hole 8 and secondary socket 7 respectively.Secondary socket 7 is to pass through tracheascope.Secondary socket 7 comprises bullet circle, and bullet circle is connected with through hole by one section of resilient sleeve.
Compared to through hole, diameter is smaller in its natural state for the bullet circle of secondary socket 7, and that is bullet circle can be expanded, and for the tracheascope that diameter is larger, can support larger by bullet circle, but the size of through hole is fixing.Can determine suitable hole size through test of many times before use, the tracheascope that diameter is greater than through hole must not insert laryngeal mask by force, breathes in order to avoid take too many passage 6 spacial influence.Through hole also serves the effect of safety filtering, and after the tracheascope similar with through-hole diameter is inserted, the space of the passage 6 stayed should be the limit taken, use before by comparison through-hole diameter to judge that can tracheascope use.
When not needing to use tracheascope, in order to avoid handle hole 8 leaks gas, can utilize a plug body on secondary socket 7, pulling up again during use.
Stationary pipes is housing parts, and answer smooth and have certain degree of hardness, its lateral cross section can be set to ellipse.For the ease of operation and adaptation human physiological structure, the bending in arcuation in the middle part of set casing 10, as shown in Figure 1.
When using tracheascope, optimum method is the guiding tube 11 utilizing an internal diameter larger than tracheascope external diameter, first extend in handle hole 8, and stretch out for the previous period from handle hole 8 always, the use be now equivalent to for tracheascope establishes passage, then uses tracheascope more easily by this passage capable of being.After Path Setup, should wait for a period of time, after observation passage 6 part is occupied, whether the breathing of patient is normal, as abnormal, should change the smaller guiding tube of external diameter 11.Guiding tube 11 can adopt plastic tube, requires that it is bent, to adapt to the overall radian of set casing 10, its inner hollow, is used for passing through tracheascope.
