The mask has simple structure, reasonable design and convenient use, and through adjusting the sizes of the leakproof air bags (7), the mask coincides with the appearance of the cheek of a patient. The mask can be used for reducing air leaks and guaranteeing oxygen supply and is convenient for emergency resuscitation and anesthesia induction and safe, convenient and reliable to use.
Description
Technical field
The invention belongs to the medical apparatus technical field, relate to a kind of anaesthetic mask, relate to a kind of leakproof anaesthetic mask specifically.
Background technology
At present, clinically patient is implemented the anaesthetic mask that general anesthesia induction, emergency resuscitation are used, comprise mask body, the air inlet of mask body upper end, the mask body lower end is provided with ring-type sealed mask air bag, and mask air bag is established a unidirectional mask air bag valve.Because old people's loss of tooth, person's facial area atrophy of seriously not becoming thin causes having sunken cheeks and with the influence of stomach tube patient stomach tube; In induction of anesthesia, emergency resuscitation process, the mask air bag of existing face shield can not be adjacent to identically with patient's facial area fully, causes the induction of anesthesia pressurization oxygen supply phenomenon that leaks air; The oxygen supply poor effect; Even cause hypoxemia, but malpractice takes place in gerontal patient's threat to life especially.Can not effectively guarantee oxygen supply during emergency resuscitation, incur loss through delay rescue opportunity, the operator attempts to reduce gas leakage through firmly pushing means such as face shield, the underbed filling of patient's bicker both sides, still is difficult to prove effective.
Summary of the invention
The present invention seeks to overcome the defective that above-mentioned prior art exists, for patient provides a kind of safe ready, guarantees oxygen supply, the adjustable anaesthetic mask of the formula of stopping to leak gas, cut the garment according to the figure.
Technical scheme of the present invention realizes in the following manner:
Leakproof anaesthetic mask comprises mask body, and the upper end of mask body is an air inlet, and the lower end is the airtight mask air bag of ring-type, and mask air bag one end is installed an one-way cock.It is characterized in that: said mask air bag is respectively equipped with the leakproof air bag near the both sides of lower jaw end, and said leakproof air bag connects an anti-gas-leak ductus bursae, the traveling in mask air bag of said anti-gas-leak ductus bursae, converge after, connect a unidirectional leakproof air bag valve.
This leakproof anaesthetic mask is simple in structure, reasonable in design, behind the employing said structure, because the leakproof air bag is the high elastic rubber material; According to the patient ' characteristic, through the adjustment gas injection what, adjust the size of leakproof air bag easily before using; Fill patient's buccal portion depression; Mask air bag and patient ' are fitted like a glove, can effectively stop gas leakage, can guarantee when induction of anesthesia, emergency resuscitation oxygen supply, safe and reliable, improved anesthesia safety and recovery success rate.

In the accompanying drawing: 1-mask body, 2-air inlet, 3-mask air bag, 4-anti-gas-leak ductus bursae, 5-leakproof air bag valve, 6-mask air bag valve, 7-leakproof air bag, 8-lower mask jaw end, 9-mask air bag lower edge.
The specific embodiment
For further disclosing technical scheme of the present invention, elaborate through embodiment below in conjunction with Figure of description.
Shown in accompanying drawing, this leakproof anaesthetic mask comprises mask body (1), and the upper end of mask body (1) is air inlet (2), and the lower end is the airtight mask air bag of ring-type (3), and said mask air bag (3) one ends are installed a unidirectional mask air bag valve (6).Be respectively equipped with leakproof air bag (7) in mask air bag (3) near the both sides of lower mask jaw end (8); Each leakproof air bag (7) connects an anti-gas-leak ductus bursae (4); Said anti-gas-leak ductus bursae (4) traveling in mask air bag (3), converge after, connect a unidirectional leakproof air bag valve (5).
Leakproof air bag (7) profile that the present invention adopts be oval basically, and this shape remedies old age, the serious deficiency that patient's face caves in of becoming thin just.According to the above persons' human dissection and facial characteristics, the recess of its face is positioned at by two bickers, also is the present anaesthetic mask part of least coincideing; The position that leakproof air bag (7) is laid is particularly crucial, and the disease population angular projection generally is seated in mask air bag (3) on lower mask jaw end (8) 1/3 horizontal lines, therefore; Be placed in leakproof air bag (7) on the mask air bag (3) of the nearly lower jaw end of anaesthetic mask (8) both sides, the minor axis of oval leakproof air bag (7) is seated in mask air bag (3) on lower jaw end (8) 1/3 place's horizontal lines, and major axis is in the inboard of mask air bag lower edge (9); Like this; Leakproof air bag (7) inflation back is to mask air bag (3) in, expand down, and vertical dimension is pressed close to patient ', through the interior pressure of adjustment leakproof air bag (7); Thereby adjust its size, reach the purpose that fits like a glove with patient '.The elastomeric material that it is high resiliency, softness that the present invention adopts the material of leakproof air bag (7), have good contractility; Can fully fill the patient ' depression; Prevent gas leakage, described leakproof air bag (7) is a capsule property structure, borrows anti-gas-leak ductus bursae (4) to link to each other with unidirectional leakproof air bag valve (5); Leakproof air bag (7) is not fitting like a glove with mask air bag (3) wall under the inflated condition, uses with general anaesthetic mask.Anti-gas-leak ductus bursae (4) traveling in mask air bag (3) of leakproof air bag of the present invention (7), converge after, connect an one-way cock (5), avoid in disorder like this, do not influence operation, simultaneously anti-gas-leak ductus bursae (4) is played a protective role.Size is at 20～40 * 30～60mm under oval leakproof air bag of the present invention (7) non-inflated state, if too small, the face of serious depression still can't all be clogged; Do not have good leak preventing effect, if excessive, leakproof air bag (7) is undue inwardly to expand; Cover schistostoma, the influence ventilation.
When use is of the present invention, earlier mask air bag (3) is inflated to suitable pressure, the face shield routine is withheld in the disease population nose; And applying light fixes, and face shield upper/lower terminal and patient's facial area are coincide, and band stomach tube patient places a side leakproof air bag (7) middle part with stomach tube; The assistant fits fully with patient's bicker two sides portion until leakproof air bag (7), or stomach tube is held fully through leakproof air bag valve (5) slowly gas injection in leakproof air bag (7); Like this, whole face shield just fits like a glove with patient ', has effectively stopped gas leakage; Guaranteed patient's oxygen supply; Make things convenient for induction of anesthesia, emergency resuscitation, improved anesthesia safety and recovery success rate, reduced the generation of anesthetic accident, complication.
