Abstract
The utility model relates to a negative-pressure absorber for foreign matters in an ear, a nose and a throat, which can effectively solve the problem of absorbing various foreign matters in the ear, the nose and the throat. The technical scheme for solving the problem is as follows: the negative-pressure absorber comprises a barrel body, a piston, a check valve and a gas pipe, wherein the piston is arranged in the barrel body; the piston comprises a piston handle and a sealing head which is arranged on the front part of the piston handle, wherein the check valve is arranged inside the upper part of the barrel body; and an absorbing pipe is arranged on a pipe hole of the barrel body on the upper part of the check valve. The negative-pressure absorber has a simple structure, an easy operation, convenience and safety in use, a low cost, a good using effect, a broad application aspect, and can be effectively used for absorbing the various foreign matters in the ear, the nose and the throat.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly a kind of otorhinolaryngology foreign body negative pressure extractor.
Background technology
At present, the doctor is to the taking-up of otorhinolaryngology foreign body, is mostly to adopt tweezers, pliers gripping or hooks up with hook.Because these pipelines are not straight, and carefully narrow, have often taken the tremendous effort and also be difficult to take out.Especially to smooth spherical and and tube wall between gapless foreign body, above-mentioned apparatus can't take out at all.Therefore, need a kind of simple, convenient, the equipment that can effectively draw all kinds foreign body in the otorhinolaryngology.
Summary of the invention
To above-mentioned, for overcoming the prior art defective, the purpose of this utility model just provides a kind of otorhinolaryngology foreign body negative pressure extractor, can effectively solve the problem of drawing all kinds foreign body in the otorhinolaryngology.
The technical scheme that this utility model solves is; Include cylindrical shell, piston, check valve and trachea, piston is contained in the cylindrical shell, piston by piston handle be contained in the forward seal head of piston handle and constitute; Cylindrical shell is equipped with check valve in the top, on the mouth of pipe of check valve top cylindrical shell suction pipe is housed.
This utility model is simple in structure, and is easy to operate, safety easy to use, and cost is low, and result of use is good, and wide application can be effective to draw all kinds foreign body in the otorhinolaryngology.
Description of drawings
Fig. 1 is the structural profile front view of this utility model.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to this utility model.
By shown in Figure 1; This utility model includes cylindrical shell, piston, check valve and trachea, and piston is contained in the cylindrical shell, piston by piston handle 2 be contained in the forward seal head 3 of piston handle and constitute; Cylindrical shell is equipped with check valve 6 in 1 top, on the mouth of pipe of check valve top cylindrical shell suction pipe 5 is housed.
In order to guarantee result of use or easy to maintenance, described seal head and piston handle are fixed on seal head by screw 4 leading section of piston handle; Described suction pipe is the elasticity flexible rubber hose, and sealing is contained on the mouth of pipe of cylindrical shell; Described cylindrical shell is circular, or adopts the cylindrical shell of the syringe of injection; Described check valve can adopt gum elastic to process; Described seal head diameter and cylinder internal diameter match and answer, and constitute hermetically-sealed construction, in case of necessity, can also on piston head, be coated with lubricating oil, make things convenient for piston in cylindrical shell, to slide up and down.
The operating position of this utility model is that the length of adjustment elastic hose during use makes elastic hose one end closely paste mutually with foreign body, spurs piston handle then; Constantly bleed, when the valve at air inlet pipe place can not be opened, the air in the elastic hose was just thin in negative pressure state; At this moment foreign body and elastic hose are adjacent to closely mutually, and the length-adjustable elastic hose of tractive, foreign body are just taken out simultaneously; Foreign body separates length-adjustable elastic hose after taking out with gas tube orifice, negative pressure disappears, and foreign body just separates with elastic hose; Simple to operate, easily and fast, efficiently solve the problem of all kinds of foreign bodies of safe sucking-off from otorhinolaryngology.
