Abstract
The invention relates to the technical field of anesthesia equipment, in particular to an oral local anesthesia device. The oral local anesthesia device structurally comprises a tooth-socket-shaped body, teeth and gingivae below the teeth can be wrapped with the body, the two ends of the body are provided with gas and liquid inlets, the middle of the body is provided with a gas and liquid outlet, one gas and liquid inlet is connected with an anesthesia mechanism through a pipeline, and the gas and liquid outlet is connected with a vacuum pump through a pipeline. Mixed gas of oxygen and anesthetics or liquid ejected by the anesthesia mechanism enters the body through the corresponding gas and liquid inlet, surface local anesthesia is conducted on the gingivae in the body, the mixed gas or liquid is sucked out of the gas and liquid outlet through the vacuum pump, and therefore a loop is formed. According to the oral local anesthesia device, oral surface anesthesia can be limited to the teeth and the gingivae, diffusion of the anesthetics is controlled effectively, the anesthesia effect is better, and the situation that human bodies absorb the anesthetics can also be avoided.
Description
Technical field
The present invention relates to anesthesia equipment technical field, particularly a kind of oral cavity partial anesthesia outfit.
Background technology
It is generally acknowledged, anesthesia is the reversibility function inhibitio of a kind of nervus centralis and (or) the peripheral nervous system produced by medicine or additive method, and the feature of this suppression mainly feels the forfeiture of the particularly pain sensation.
For clinical anesthesia, mainly comprise general anesthesia and local anesthesia.
Local anesthesia utilizes local anesthetic as procaine, lignocaine etc., is injected at corresponding site and spinal nerves, plexus nervorum or nerve trunk and the thinner peripheral termination of nerve are blocked, a certain position of health is temporarily lost sensibility.The feature of local anesthesia is exactly " locally " that anesthesia is confined to health, and the consciousness of patient is clear-headed.Conventional method comprises intravertebral anesthesia (retardance), nerve block, field block, local infiltration anesthesia and topical anesthesia etc.
Topical anesthesia is by local anesthetic strong for permeability spraying or is coated on the surface such as mucosa, conjunctiva to produce anesthetic action.
For superficial anesthesia of mouth be by anesthetis coating or spray in field of operation surface, anaesthetic is absorbed, local nerve tip benumb, analgesis, thus the effect reaching anesthesia.Be applicable to Abscess incision drain under oral mucosa, pull out loosening deciduous teeth, and the mucomembranous surface anesthesia before endotracheal intubation.Conventional medicine is the tetracaine of 1% ~ 2%, and its anaesthetic effect is stronger; But because it is toxic, expansible blood vessel and strengthen the speed of drug absorption again, therefore dosage will be noted in use, or in tetracaine, add a small amount of epinephrine.
Current superficial anesthesia of mouth, the apparatus of its method and use, generally utilize the anesthesia spray gun with shower nozzle, directly the part of anesthesia is being needed to carry out spraying or smearing, its operation is higher to the requirement of medical personnel, and for anaesthetic, is easy to after injection is smeared, enter inside of human body by the esophagus of people, thus cause unnecessary untoward reaction.
Summary of the invention
In order to solve the problem of prior art, the invention provides a kind of oral cavity partial anesthesia outfit, superficial anesthesia of mouth can be confined to tooth and gingiva place by it, and effectively controls narcotic diffusion, not only anaesthetic effect is better, and human body can be avoided to take in the problem of anaesthetic.
The technical solution adopted in the present invention is as follows:
A kind of oral cavity partial anesthesia outfit, comprise the body of a facing type, described body can wrap the gingiva below tooth and tooth, on body, two ends are provided with gas-liquid import, middle part is provided with gas liquid outlet, described gas-liquid import connects anesthesia mechanism by pipeline, and described gas liquid outlet connects vacuum pump by pipeline; The oxygen of anesthesia mechanism ejection, narcotic mist or liquid enter in body through gas-liquid import, carry out surperficial local anesthesia to intrinsic gingiva, and by gas liquid outlet by vacuum pump sucking-off, thus form a loop.
The beneficial effect that technical scheme provided by the invention is brought is:
By the body design of facing type, gum portion to be anaesthetized is made to be rolled into an independently space by body, by gas-liquid import, narcotic injection is carried out to this space, thus enable it need the carrying out of the part highly effective and safe of anaesthetizing to anaesthetize, by gas liquid outlet, anesthetis and other gas liquids such as oxygen or water are extracted out at any time, make it can not rest in oral cavity, avoid many deficiencies of ejection-type anesthesia method under prior art, and the anesthesia of separate space formula also makes, and anaesthetic effect is better to be concentrated.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment one:
As shown in Figure 1, a kind of oral cavity partial anesthesia outfit, comprise the body 1 of a facing type, described body 1 can wrap the gingiva below tooth and tooth, on body 1, two ends are provided with gas-liquid import 2, middle part is provided with gas liquid outlet 3, and described gas-liquid import 2 connects anesthesia mechanism 5 by pipeline 4, and described gas liquid outlet 3 connects vacuum pump 7 by pipeline 6; Oxygen, narcotic mist or liquid that anesthesia mechanism 5 sprays enter in body 1 through gas-liquid import 2, carry out surperficial local anesthesia to the gingiva in body 1, and by gas liquid outlet 3 by vacuum pump 7 sucking-off, thus form a loop.
As shown in accompanying drawing 2,3, the body 1 of the present embodiment is made up of tooth portion 11, gingiva portion 12, described tooth portion 11 connects gingiva portion 12 downward or upward, described tooth portion 11 and gingiva portion 12 can wrap up the below tooth of people and gingiva or top tooth and gingiva completely, and described tooth portion 11 with the inwall of the join domain in gingiva portion 12 are provided with gas-liquid gathering sill 13.
Gingiva portion 12 is protruding laterally, and form the space 14 that can hold gas-liquid, described space 14 top edge arranges described gas-liquid gathering sill 13.
In the present embodiment, space 14 in gingiva portion 12, can facilitate oxygen, narcotic mist or liquid can at gingiva place deposition polymerization, thus the anaesthetic effect strengthened gingiva top layer, gas-liquid gathering sill above it 13 is responsible for making oxygen, narcotic mist or liquid have one to flow to passage, make it can under the pressure effect of vacuum pump, moved to gas liquid outlet 3 by gas-liquid import 2, and then sucking-off, thus form a loop, and can not stop for a long time in oral cavity and ooze out outside body 1.
Body 1 only need be engaged on the upper jaw or lower jaw by patient, by anesthesia, oxygen, narcotic mist or liquid inject in mechanism, such as need to anaesthetize lower-left jaw, the body 1 of applicable lower jaw is engaged by patient, the pipeline connecting anesthesia mechanism 5 is plugged in the gas-liquid import 2 in left side, the pipeline connecting vacuum pump 7 is connected on the gas liquid outlet 3 at middle part, the anesthesia tooth gingiva of lower-left jaw being needed to position can be realized.
