Description
Technical field
This utility model relates to medical instruments field, relates to a kind of throat anesthesia outfit specifically.
Background technology
When carrying out treating under fiberoptic bronchoscopy and mirror, the anesthesia of ideal, safety is the guarantee of successful operation.A kind of simple, reliable throat anesthetic needle design is provided in patent CN202236691U.But in use, the needle tubing partial-length of this throat anesthetic needle is larger, and when syringe shifts the end onto, a large amount of liquor residue is in needle tubing, causes medicinal liquid use amount inaccurate, also causes waste.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned defect, provides a kind of throat anesthesia outfit of noresidue medicinal liquid.
For solving the problem, the technical scheme that this utility model adopts is:
A kind of throat anesthesia outfit, comprise syringe, described syringe comprises syringe, described syringe bottom surface is provided with the first opening and the second opening, described first opening is connected with the first check valve, and described second opening is connected with conduit, is provided with the second check valve between described second opening and conduit.
Improve as one: described second check valve comprises shell described in shell and is provided with two openings, one of them opening is provided with mesh plate, non-return pipe, described non-return pipe is flexible waterproof pipe, and the opening that described shell is provided with mesh plate is connected with the second opening, another opening and tubes connection.
Improve as one: described non-return pipe area of section from the side near mesh plate reduces gradually.
Improve as one: described non-return pipe is polyethylene film pipe.
Owing to have employed technique scheme, medicinal liquid all can be sent to patient part by this utility model, noresidue, and dose uses accurately, ensures anaesthetic effect, cuts the waste.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
Embodiment:
As shown in Figure 1, 2, a kind of throat anesthesia outfit, comprise syringe, described syringe comprises syringe 1, piston 10 and needle handle 11, described syringe 1 bottom surface is provided with the first opening 2 and the second opening 3, described first opening 2 is connected with the first check valve 4, and described second opening 3 is connected with conduit 6, is provided with the second check valve 5 between described second opening 3 and conduit 6.
Described second check valve 5 comprises shell 8 described in shell 8 and is provided with two openings, one of them opening is provided with mesh plate 7, non-return pipe 9, described non-return pipe 9 is polyethylene film pipe or other flexible waterproof pipes, the opening that described shell 8 is provided with mesh plate 7 is connected with the second opening 3, and another opening is connected with conduit 6.
Described non-return pipe 9 area of section from the side near mesh plate 7 reduces gradually.
This utility model in use, first conduit 6 is goed deep into patient's throat, promote needle handle 11 medicinal liquid is sent into, then to pull back needle handle 11, non-return pipe 9 shrinks under pressure and is adjacent to mesh plate 7, stops the backflow of conduit 6 inner liquid medicine, simultaneously owing to sucking the air after air or purification in the effect syringe 1 of the first check valve 4, promote needle handle 11 again, non-return pipe 9 conduit 6 inner liquid medicine that is open is sent to affected part.
Syringe 1 can suck medicinal liquid by the first check valve 4 and the first opening 2, also can close the first check valve 4 and suck medicinal liquid from the second opening 3.
Described second check valve 5 removably connects with conduit 6, and described second check valve 5 removably connects with syringe 1.
