Description
This utility model relates to branchofiberoscope, particularly a kind of bronchoscope valve that integrates oxygen supply, attracts.
At present, no matter existing branchofiberoscope is the product of optical instrument factory, Shanghai or the Olympus of Japan, and its biopsy duct all has only the attraction function, oxygen supply simultaneously except that carrying out operation such as biopsy.It is for the critical patient that indication is arranged or the patient of hypoxemia is arranged itself, because when fiberoptic bronchoscopy, patient's blood oxygen pressure, general decline 1.333-2.666KPa, and can not carry out bronchoscopy and treatment, thus delay treatment, until patient death.
The purpose of this utility model provides a kind of bronchoscope valve that integrates oxygen supply, attracts, and makes it both keep original attraction function, can pass through branchofiberoscope biopsy hole again, directly oxygen is sent in the bronchus.
The purpose of this utility model is to be achieved through the following technical solutions: it is the improvement that attracts the attraction button on the hole to carry out to bronchoscope, its mainly comprise column type valve casing, attract valve, valve gap etc., attract valve to be connected with valve casing by screw thread, and communicate with cavity in the valve casing, the interface section of valve casing connects with bronchoscope, be socketed with two sealing rings on the interface section, valve gap is connected by an end of screw thread and valve casing.Cavity in the valve casing is 3 degree taperings, its end diameter is greater than the interface section intracavity diameter, have the one handle groove along the valve casing surrounding, handle groove communicates with valve shell cavity, the two ends of handle groove and valve shell cavity axis constitute 120 degree angles, one oxygen supply valve is set on valve casing parallel with air-breathing valve on the valve casing, the oxygen supply valve is connected with valve casing also by screw thread and valve shell cavity communicates, the oxygen supply valve is 120 degree angles with attracting valve, on the valve casing between oxygen supply valve axis direction and the valve casing handle groove, have a steam vent, cavity in steam vent and the valve casing communicates, one rotating valve body is installed in valve casing, and its shape and valve shell cavity adapt, and 3 degree taperings are arranged, valve body is an end sealing hollow structure, and an end that does not seal communicates with the cavity of the blank area of valve casing.One pore is arranged on the valve body, and pore communicates with its inner chamber, valve body rotate the different angles pore can be respectively with valve casing on two valves communicate straight-through.
In the handle groove on valve casing one handle is arranged, handle is connected with valve body by screw thread.On the valve body surface of both sides, handle silk hole, be 60 degree, 120 degree respectively have a groove.
Between valve gap and valve body, there is a spring to be used to hold out against valve body.
Described bronchoscope valve is the improvement that existing branchofiberoscope is attracted button, it had both kept original attraction function, simultaneously can utilize valve switch directly oxygen to be sent in trachea, the bronchus again, make patient's blood oxygen pressure in fiber bronchus checking process not reduce and can raise to some extent by the attraction button of branchofiberoscope.In clinical trial, rescued the 62 examples patient that suffocates, all obtained good efficacy, also can check and treat conventional incompatible patient is arranged, thereby enlarged bronchoscopic range of application.
This utility model is simple in structure, easy to use, and the diameter and the shape of the interface section that it can be connected with branchofiberoscope by the conversion valve can apply to different types of branchofiberoscope, and removable cleaning and soaking disinfection, guard against cross infection.
Below in conjunction with embodiment this utility model is further described:
Fig. 1 is this utility model structural representation.
Fig. 2 is the front section view of Fig. 1.
As shown in the figure, it mainly comprises columniform valve casing 1, attracts valve 3, valve gap 6.Attract valve 3 to be connected with valve casing 1 by screw thread, and communicate with the interior cavity of valve casing 1, the interface section 9 of valve casing 1 connects with bronchoscope, is socketed with two sealing rings 10 on the interface section 9, and valve gap 6 is connected by an end of screw thread and valve casing 1.The cavity of valve casing 1 is 3 degree taperings, its end diameter is greater than the intracavity diameter of valve casing interface section 9, around valve casing 1, have one handle groove 11, this groove communicates with valve casing 1 inner chamber, the two ends of handle groove 11 and valve shell cavity 1 axis constitute 120 degree angles, on the valve casing 1 parallel, an oxygen supply valve 8 is set with air-breathing valve 3, oxygen supply valve 8 be connected with valve casing 1 by screw thread and and valve casing 1 inner chamber communicate, oxygen supply valve 8 with attract valve 3 to be 120 to spend angles.Between the axis direction of oxygen supply valve 8 and valve casing handle groove, have a steam vent 7, cavity in steam vent 7 and the valve casing 1 communicates, one rotating valve body 2 is installed in valve casing 1, its shape and valve casing 1 inner chamber adapt, and have 3 to spend taperings, valve body 2 is an end sealing hollow structure, and its end that does not seal communicates with the cavity of the interface section 9 of valve casing 1.One pore is arranged on the valve body 2, and pore communicates with its inner chamber, valve body rotate the different angles pore can be respectively with valve casing 1 on two valves communicate straight-through.
One handle 4 is arranged in the handle groove on valve casing 1, and handle 4 is connected with valve body 2 by screw thread.Because of oxygen cylinder frequent switch in use, thereby on valve body 2 surfaces of both sides, 4 holes of handle, be 60 degree, 120 degree respectively have a groove, so that under the situation of not oxygen uptake, oxygen enters this two groove by the oxygen supply valve, further emits by the steam vent on the valve casing 17.Between valve gap 6 and valve body 2, there is a spring 5 to be used to hold out against valve body 2.
During use former bronchoscopic attraction button is taken off, the valve connection is upward got final product.When use attracting function, handle 4 is gone to an end of handle groove, the pore on the valve body 2 is communicated with attraction valve 3 on the valve casing, the liquid in the bronchoscope is drawn from attraction valve 3.Gas in the valve of oxygen supply simultaneously 8 is flowed out by steam vent 7 by the groove on the valve body surface.When using the oxygen supply state, handle 4 is pushed into the other end of handle groove, pore on the valve body 2 and oxygen supply gas valve 8 communicate, and this moment, gas entered the cavity of valve body 2 by oxygen supply valve 8, thereby further flowed into bronchus by the cavity of valve casing 1 interface section 9.When using former bronchoscopic injection function, handle is gone to the centre position, this moment, two valves did not all communicate with the cavity of valve body, medicine can inject through former medicine-pouring hole, and the gas in the oxygen hose further flows out by steam vent 7 by the groove that oxygen supply valve 8 enters on the valve body, prevents the hypertonia in the oxygen hose.
