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, an oral local anesthesia device includes a brace-shaped body 1, the body 1 can wrap teeth and the gums under the teeth, the body 1 is provided with gas-liquid inlets 2 at both ends, and the middle is provided with gas-liquid inlets 2 Outlet 3, the gas-liquid inlet 2 is connected to the anesthesia facility 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 sprayed by the anesthesia facility 5 is through the gas The liquid inlet 2 enters the body 1 to perform surface local anesthesia on the gums in the body 1, and is sucked out by the vacuum pump 7 from the gas-liquid outlet 3, thereby forming a loop.

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

Embodiment 2

[0026] The first embodiment is a single-layer body design, which is suitable for anesthesia with only lower teeth or upper teeth.

[0027] This embodiment provides a double-layered body. The body 1 is composed of a lower jaw portion 111 and an upper jaw portion 112. The lower jaw portion 111 and the upper jaw portion 112 are connected by a connecting portion 113. The lower jaw portion 111 or the upper jaw portion 112 They are respectively composed of a tooth portion 11 and a gum portion 12, the tooth portion 11 is connected downward or upward to the gum portion 12, and the tooth portion 11 and the gum portion 12 can completely wrap the lower teeth and gums of a person or the upper teeth and gums 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 that both upper and lower gums need anesthesia. The patie...

Embodiment 3

[0030] The difference between this embodiment and the first and second embodiments is that, in order to achieve a better sealing effect, a flexible gasket 8 can be provided on the edge of the body 1, and the flexible gasket 8 can be tightly absorbed with the gums, thereby The tooth part 11, the gum part 12 and the wrapped tooth and gum form a relatively sealed environment, thereby increasing the effect of anesthesia and reducing the influence of the leakage of anesthetic.

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 [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 reversible functional inhibition of the central nervous system and (or) peripheral nervous system produced by drugs or other methods. This inhibition is mainly characterized by loss of sensation, especially pain. [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 part to block the spinal nerve, nerve plexus or nerve trunk and finer peripheral nerve endings, and temporarily lose sensation in a certain part of the body . The characteristic of local anesthesia is that the anesthesia is limited to the "parts" of the body, and the patient's consciousness is clear. Commonly used methods include intraspinal ...
