Problems solved by technology

[0007] The current surface anesthesia of the oral cavity, its method and the equipment used generally use an anesthesia spray gun with a nozzle to spray or smear directly on the part that needs anesthesia. It is easy to enter the human body through the human esophagus after spraying, thus causing unnecessary adverse reactions

Embodiment 1

[0020] as attached figure 1 As shown, a local anesthesia device for the oral cavity includes a mouthpiece-shaped body 1, the body 1 can wrap the teeth and the gums below or above the teeth, the two ends of the body 1 are provided with gas-liquid inlets 2, and the middle part is provided with The gas-liquid outlet 3, the gas-liquid inlet 2 is connected to the anesthesia mechanism 5 through the pipeline 4, and the gas-liquid outlet 3 is connected to the vacuum pump 7 through the pipeline 6; the mixed gas or liquid of oxygen and anesthetic agent ejected by the anesthesia mechanism 5 Enter the body 1 through the gas-liquid inlet 2, perform local anesthesia on the gums in the body 1, and suck it out through the gas-liquid outlet 3 by the vacuum pump 7, thereby forming a circuit.

[0021] as attached figure 2 , 3 As shown, the body 1 of this embodiment is composed of a tooth part 11 and a gum part 12. The tooth part 11 is connected to the gum part 12 downward or upward, and the t...

Embodiment 2

[0026] Embodiment 1 is a single-layer body design, which is suitable for anesthesia of only mandibular teeth or maxillary teeth.

[0027] This embodiment provides a double-layer body. The body 1 is composed of a lower jaw part 111 and an upper jaw part 112. The lower jaw part 111 and the upper jaw part 112 are connected by a connecting part 113. The lower jaw part 111 or the upper jaw part 112 It is composed of tooth part 11 and gum part 12 respectively, and the tooth part 11 is connected to the gum part 12 downward or upward, and the tooth part 11 and the gum part 12 can completely wrap the lower teeth and gums or the upper teeth and gums of a person. A gas-liquid guide groove 13 is provided on the inner wall of the connection area between the tooth portion 11 and the gum portion 12 .

[0028] The double-layer body structure provided in this embodiment is suitable for the situation where the upper and lower gums need anesthesia. The patient only needs to bite the body 1 betwe...

Embodiment 3

[0030] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that in order to achieve a better sealing effect, a flexible sealing pad 8 can be provided on the edge of the body 1, and the flexible sealing pad 8 can be closely adsorbed to the gums, thereby The teeth part 11, the gum part 12 and the wrapped teeth and gums form a relatively sealed environment, thereby increasing the effect of anesthesia and reducing the impact of leakage of the anesthetic.

Abstract

The invention relates to the technical field of anesthesia equipment, in particular to an oral local anesthesia device. Its structure includes a mouthpiece-shaped body, which can wrap the teeth and the gums below or above the teeth. There are gas-liquid inlets at both ends of the body, and a gas-liquid outlet in the middle. The gas-liquid inlet passes through the tube The gas-liquid outlet is connected to the vacuum pump through the pipeline; the mixed gas or liquid of oxygen and anesthetic agent sprayed out by the anesthesia mechanism enters the body through the gas-liquid inlet, and the gingiva in the body is locally anesthetized, and the gas The liquid outlet is sucked out by the vacuum pump, thus forming a loop. The oral local anesthesia device of the present invention can limit oral surface anesthesia to teeth and gums, and effectively control the diffusion of anesthetics, which not only has better anesthesia effect, but also can avoid the problem of human body taking anesthetics.

Description

technical field [0001] The invention relates to the technical field of anesthesia equipment, in particular to an oral local anesthesia device. Background technique [0002] It is generally believed that anesthesia is a kind of reversible functional inhibition of the central nervous system and (or) peripheral nervous system produced by drugs or other methods. The main feature of this inhibition is the loss of sensation, especially pain sensation. [0003] For clinical anesthesia, it mainly includes general anesthesia and local anesthesia. [0004] Local anesthesia is the use of local anesthetics such as procaine, lidocaine, etc., injected into the corresponding parts to block the spinal nerves, nerve plexus or nerve trunks and thinner peripheral nerve endings, so that a certain part of the body temporarily loses feeling . The characteristic of local anesthesia is that the anesthesia is limited to the "local" of the body, and the patient's consciousness is awake. Commonly u...
