Abstract

This is a anesthesia spray gun with double interfaces, including handle, varied diameter pipe and spray pipe. The handle forked tail, the handle and the varied diameter pipe are integrated. The spray pipe and the varied diameter pipe are connected. 4cm to 5 cm of the spray pipe at the front end is made into an arc. The bending angle is 18 degrees-22 degrees. Four side wall spray holes are in the front end of the spray pipe. Scale is marked on the spray pipe. A built-in steel needle tube and double interfaces neilsbed tube are in the internal cavity formed by the handle forked tail, handle and the various diameter pipe. The double interfaces neilsbed tube and the built-in steel needle tube are connected. The built-in steel needle tube goes through the various diameter pipe and inserts into the spray pipe. The utility model can reach the throat, the glottis and the parts below glottis. Anesthesia of pharynx posterior wall, epiglottis, glottis and trachea can be operated by several times according to the need with the scale. The effective area of anesthesia is increased and the synchronous oxygen supply is executed. The utility model can be used in stomatology and otolaryngolory.

Description

Double nip rifle formula anesthesia aerosol apparatus

Technical field: this utility model relates to a kind of anesthesia aerosol apparatus, particularly a kind of double nip anesthesia aerosol apparatus.

Background technology: the anesthesia aerosol apparatus is one of Anesthesia Department's intubate apparatus commonly used, and especially utilization rate reaches absolutely in conscious intubation.The anesthesia aerosol apparatus of present clinical use can be divided into three kinds of the attached thin plastic pipes of kettle formula aerosol apparatus, rifle formula aerosol apparatus and syringe.Though kettle formula aerosol apparatus is reliable for effect to the topical anesthesia of oral cavity, pharynx, nasal cavity, the topical anesthesia difficulty reaches under larynx, glottis and the glottis, often needs to cooperate thyrocricoid puncture before tracheal intubation, and can not effectively calculate the local anaesthetics consumption; Spray though rifle formula aerosol apparatus can go deep into glottis, its front end has only a jet, and the topical anesthesia effective area is limited; The attached thin plastic pipe of syringe is because the plastic tube material is softer, and through glottis injection difficulty, difficulty reaches quantitatively, locatees the purpose of carrying out topical anesthesia, can not implement standardized operation.Above-mentioned three kinds of anesthesia aerosol apparatus as the need oxygen supply, also need adopt other approach in implementing the anesthesia procedure process.Raising along with medical level, medical personnel more and more need a kind of, can get at and reach larynx, glottis and infraglottic position, can intuitively arrive the position of required anesthesia again with locating, can also increase the effective area of anesthesia simultaneously and implement the anesthesia aerosol apparatus of synchronous oxygen supply.

Summary of the invention: in order to address the above problem, this utility model provides a kind of can getting to reach larynx, glottis and infraglottic position, can intuitively arrive the position of required anesthesia again, the while can also increase the effective area of anesthesia and implement the anesthesia aerosol apparatus of synchronous oxygen supply with locating.

In order to finish above-mentioned purpose, the technical solution adopted in the utility model is: a kind of double nip

Rifle formula anesthesia aerosol apparatus, comprise handle, reducer pipe, injection spray pipe, handle dovetail, handle and reducer pipe are connected as a single entity, injection spray pipe is connected with reducer pipe, 4cm to 5cm makes camber from the injection spray pipe front end, angle of bend is 18 °～22 °, the injection spray pipe front end has four sidewall spray holes, scale marker is carved with on the injection spray pipe surface, in the inner chamber that forms by handle dovetail, handle and reducer pipe built-in draw point pipe and double nip needle stand pipe are arranged, double nip needle stand pipe is connected with built-in draw point pipe, and built-in draw point pipe passes reducer pipe and inserts in the injection spray pipe.Wherein preferred angle of bend is 20 °.

The beneficial effects of the utility model are: the Front-end Design at injection spray pipe has four sidewall spray holes, when implementing anesthesia, the main spray holes synergism of four sidewall spray holes and injection spray pipe front end helps the diffusion of local anaesthesia medicine, thereby increases the effective area of topical anesthesia.

People's front tooth to the length of epiglottis is about 11～13cm, front tooth to the length of glottis is about 13～15cm, front tooth segment length to the trachea is about 20～24cm, scale marker is carved with on surface at injection spray pipe, help the position that clear and definite operational depth of operator and topical anesthesia are reached, utilize injection spray pipe of the present utility model to carry out oral cavity and pharynx mucosa table fiber crops, and anaesthetize to swallowing rear wall, epiglottis, glottis and trachea in conjunction with the progressive gradation of scale marker as required, in use can calculate the total amount of employed local anaesthesia medicine.

When making injection spray pipe, make arc at the front end of injection spray pipe, to reduce the sense of discomfort of patient in the anesthesia procedure process.

The bore conformance with standard syringe interface of two interfaces of double nip needle stand pipe, a termination topical anesthesia syringe wherein, another termination oxygen in the topical anesthesia process, gives oxygen uptake in conjunction with patient, with the supply of oxygen in effective solution topical anesthesia process.

During use, according to the position that will anaesthetize and the degree of depth, determine scale marker, injection spray pipe is inserted in the disease population, an interface of double nip needle stand pipe connects anesthetic syringe and injects anaesthetic, and anaesthetic is through double nip needle stand pipe, built-in draw point pipe, injection spray pipe, and the main spray holes by four sidewall spray holes and injection spray pipe front end sprays into the position that patient need anaesthetize, another interface of double nip needle stand pipe inserts oxygen, gives oxygen supply according to patient.

After double nip anesthesia aerosol apparatus is finished using, can adopt multiple disinfection way to carry out disinfection, as glutaraldehyde soaking disinfection, oxirane or formaldehyde sterilization.Reduce waste like this, reduced cost.This utility model also can be used for the department of stomatology, department of otorhinolaryngology.

Description of drawings

Fig. 1 is an overall schematic of the present utility model.

Fig. 2 is that internal anatomy is amplified in the part of A.

The specific embodiment:

Handle dovetail 1, handle 2 and reducer pipe 3 are connected as a single entity,

injection spray pipe

4 and 3 gluing connections of reducer pipe, do camber from the front end 4cm to 5cm of injection spray pipe 4, angle of bend a is 20 °, injection spray pipe 4 front ends have four sidewall spray holes 7, scale marker 8 is carved with on injection spray pipe 4 surfaces, in the inner chamber that forms by handle dovetail 1, handle 2 and reducer pipe 3 built-in draw point pipe 6 and double nip needle stand pipe 5 are arranged, double nip needle stand pipe 5 and built-in 6 gluing connections of draw point pipe, built-in draw point pipe 6 pass reducer pipe 3 and insert in the injection spray pipe 4.

Injection spray pipe 4 length overalls are 20cm, and every 1cm carves a scale marker 8, the bore conformance with standard syringe interface of two interfaces of double nip needle stand pipe 6.When implementing anesthesia, an interface connects syringe and injects the topical anesthesia medicine, and another interface inserts oxygen, guarantees the supply of oxygen in the operating process.Injection spray pipe 4 adopt be difficult for tortuous deformation, tube wall is thin and internal diameter is big relatively, can make arc and the plastic tube of hardness is arranged.
