Abstract
The utility model relates to a during the tracheal surgery for right angle air injection needle to patient's oxygen suppliment, it comprises air injection needle bar, connection suspension needle bar and needle handle, air injection needle bar with be connected suspension needle bar mutually perpendicular and communicate with each other, the afterbody at the suspension needle bar is connected to the needle handle. The defect that oxygen input in the prior art often forms vortex and is not easy to enter the respiratory tract of a patient is overcome, and medical accidents of asphyxia, sudden cardiac arrest, death and the like of the patient due to oxygen deficiency are reduced.
Description
This utility model relate to a kind of with medium fail in or input people intravital device, be a kind of when operation on trachea specifically, be used for to the right angle of patient's oxygen supply ventilation nozzle needle.
When performing the operation in the trachea, generally all need to patient's oxygen supply, existing method for supplying oxygen is to offer an oxygen supply hole at the bronchoscope sidewall that operation is used, and this oxygen supply hole joins by a connecting line and respirator, thereby reaches the purpose of oxygen supply.But the shortcoming of this method for supplying oxygen is: from sidewall oxygen supply hole deviation to entering bronchoscopic air-flow, know after tested that it does not have or seldom enters respiratory tract, also flow out from bronchoscopic outlet in the other direction but form eddy current, sometimes even can make and occur negative pressure appearance in the bronchoscope, this is for very easily taking place because of malpracticees such as anoxia is suffocated, cardiac arrest, death because of foreign body in trachea hinders patient, the especially infant of ventilation.
The purpose of this utility model is to provide a kind of breather, and the air-flow that flows in the bronchoscope by this device vortex phenomenon can not occur, can flow into the patient respiratory road smoothly, can fully satisfy the oxygen supply requirement of patient in the operation on trachea process.
Technical solution of the present utility model is: a kind of right angle ventilation nozzle needle, hang shank and needle handle is formed by jet shank, connection, and described jet shank is with to be connected the suspension shank mutual vertical and communicate, and described needle handle is connected the afterbody of suspension shank.
Jet shank in this utility model hangs shank and should adopt rustless steel shank or other metal shank with being connected, and so not only can guarantee its intensity, but also can make it have certain weight, unlikely pulse pneumatic by the time jumping phenomena appears.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a user mode sketch map of the present utility model;
Referring to Fig. 1, this right angle ventilation nozzle needle hangs shank 2 by the jet shank 1 of rustless steel, connection and needle handle 3 is formed, jet shank 1 be connected that to hang shank 2 vertical mutually and communicate, its place, right angle is an arc transition, needle handle 3 be connected the afterbody that hangs shank 2 and connect, its effect is to be convenient to connect the oxygen supply conduit.
Referring to Fig. 2, during use jet shank 1 is inserted bronchoscope 6, will connect suspension shank 2 and hang over the bronchoscopic mouth of pipe, and the oxygen supply conduit 4 of needle handle 3 same connections breathings 5 will be joined, can reach purpose like this to patient's oxygen supply.
Because the airflow direction that adopts this utility model to feed parallels with the gas channel of tracheascope, thereby can not produce eddy current, can enter respiratory tract smoothly.Show by clinical practice and zooperal monitoring, under the identical situation of ventilator parameter, the ventilation of right angle ventilation nozzle needle and make oxygen concentration that the patient sucks apparently higher than prior art, can satisfy the oxygen supply requirement of operation process in the trachea, significantly reduce malpracticees such as suffocating of occurring because of oxygen supply is not enough, cardiac arrest and death.
Claims (2)
1, a kind of right angle ventilation nozzle needle is characterized in that: hang shank and needle handle is formed by jet shank, connection, described jet shank is with to be connected the suspension shank mutual vertical and communicate, and described needle handle is connected the afterbody of suspension shank.
2, ventilation nozzle needle in right angle according to claim 1, it is characterized in that: it is the rustless steel shank that shank is hung in described jet shank, connection.
