Abstract
The utility model relates to an trachea and bronchus dual-type catheter, which comprises a ventilation pipe, a ventilation hole, a cylindrical sleeve bag, a spherical sleeve bag, a switch sleeve, a switch handle and a connector. The ventilation pipe is provided with a standard connector, and is also provided with a hole of Murphy close to the patient end and a Y-shaped tube close to the machine end; the top end of the Y-shaped tube is provided with a limit plug; the switch handle comprises a wire and is provided with two fixed cursors; the cylindrical sleeve bag comprises a cylindrical bag, a cylindrical bag inflation pipe, a cylindrical bag indication bag and a cylindrical bag one-way valve; and the spherical sleeve bag comprises a spherical bag, a spherical bag inflation pipe, a spherical bag indication bag and a spherical bag one-way valve. The utility model has the advantages of not only realizing the one-lung ventilation, but also achieving the ventilation of the bronchus. The doctor does not need to worry about the positioning of the catheter; the ventilation state required for an operation can be realized through inflating different sleeve bags and opening and closing different ventilation holes; and the utility model not only facilitates the operation of the doctor, but also reduces the risk factor of the patient and the damage to the patient due to the repeated intubation.
Description
Technical field
This utility model relates to a kind ofly medical can satisfy trachea and the bronchus dual-purpose conduit that tracheal intubation also can bronchial cannula realizes one-lung ventilation.
Background technology
When using the double lumen endobronchial tube intubate, be not easy successfully clinically, cause repeatedly intubate to increase patient trauma, also cause a lot of puzzlements for the doctor because of the location.It is easy, easy to operate just to be sought after a kind of location so clinically, can realize the endotracheal tube of one-lung ventilation again.
The utility model content
This utility model not only can be realized one-lung ventilation, also can work as common endotracheal tube and use, and the doctor does not worry the orientation problem of conduit, as long as insert bronchus, fills up different cover capsules and adjusts and switch sleeve pipe and can realize the aeration status of performing the operation and needing.So not only make things convenient for doctor's operation, also reduced patient's danger coefficient and the damage that brings to patient of intubate repeatedly.
The technical scheme in the invention for solving the technical problem is:
A kind of trachea and bronchus dual-purpose conduit, it comprises: breather, passage, cylindrical sleeve capsule, spherical cover capsule, switching sleeve pipe, switching handle, joint.On its Center Vent tube modular connection is arranged, breather has black Fei Shi hole near patient end, near machine end Y tube is arranged, and switches handle and passes the restricted plug in Y tube top thus; Switching handle is an one metal wire, and two fixedly verniers are arranged on it, is used for control and switches telescopic range of activity, thereby realize opening or closing of passage; The cylindrical sleeve capsule comprises cylindricality capsule, cylindricality capsule gas tube, cylindricality capsule indication capsule and cylindricality capsule check valve, and spherical cover capsule comprises spherical capsule, spherical capsule gas tube, spherical capsule indication capsule and spherical capsule check valve; When filling up the cylindricality capsule, open passage, this trachea and bronchus dual-purpose conduit can be used as common endotracheal tube and use, and gas can be from being positioned at the passage turnover at trachea position, and two lungs all can be ventilated; When close passage, when the cylindrical sleeve capsule is not inflated, gas passes in and out in bronchus, gas is opened back intrapleural negative pressure disappearance because of the thoracic cavity in the operation side lung, the elastance of lung retraction, gas flows out external through the gap of body and inner surface of trachea in lung in the lung, therefore operation side lung subsides, and makes things convenient for the operation in doctor's art, thereby has also realized one-lung ventilation.
Described passage has several, is positioned on the breather tube wall, and the diameter summation of its all passages is greater than breather patient end diameter.
Described switching sleeve pipe is positioned at and is provided with passage position inwall, and the switching that is attached thereto handle passes from the Y-piece top.
Following 1/3rd places of described endotracheal tube between two inflatable cuff are tiny gradually, to adapt to the bronchus size.
Can be divided into different size according to the diameter of its breather and this trachea of length and bronchus dual-purpose conduit.
Description of drawings
Fig. 1 is a side view of the present utility model;
The specific embodiment
As shown in Figure 1, a kind of trachea and bronchus dual-purpose conduit, it comprises: breather 1, passage 2, cylindrical sleeve capsule 3, spherical cover capsule 4, switching sleeve pipe 5, switching handle 6, joint 7.On its Center Vent tube 1 modular connection 7 is arranged, breather 1 has black Fei Shi hole 1-1 near patient end, near machine end Y tube 1-2 is arranged, and switches handle 6 and passes Y tube 1-2 top restricted plug 1-3 thus; Switching handle 6 is one metal wires, and two fixedly vernier 6-1 are arranged on it, is used to control the range of activity of switching sleeve pipe 5, thereby realizes opening or closing of passage 2; Cylindrical sleeve capsule 3 comprises cylindricality capsule 3-1, cylindricality capsule gas tube 3-2, cylindricality capsule indication capsule 3-3 and cylindricality capsule check valve 3-4, and spherical cover capsule 4 comprises spherical capsule 4-1, spherical capsule gas tube 4-2, spherical capsule indication capsule 4-3 and spherical capsule check valve 4-4;
Inserting the right side bronchus with trachea and bronchus dual-purpose conduit is example.When trachea and bronchus dual-purpose conduit insertion right side bronchus, spherical cover capsule 4-1 is positioned at the right side bronchus, and cylindrical sleeve capsule 3-1 is positioned at left bronchus opening top.
When filling up cylindricality capsule 3-1, spherical cover capsule 4-1, opening passage 2, this trachea and bronchus dual-purpose conduit can be realized two pulmonary ventilation;
Pass in and out in right bronchus when closing passage 2 gases, realize single (right side) pulmonary ventilation.
If left side open chest surgery, close passage 2, cylindrical sleeve capsule 3-1 does not inflate, gas is opened back intrapleural negative pressure disappearance because of the thoracic cavity in the left pulmonary, the elastance of lung retraction, gas flows out external through the gap of body and tracheal bronchus inwall in lung in the lung, therefore left pulmonary subsides, and makes things convenient for the operation in doctor's art, thereby has also realized one-lung ventilation.
Described passage 2 has several, is positioned on breather 1 tube wall, and the diameter summation of its all passages 2 is greater than breather 1 patient end diameter.
Described switching sleeve pipe is positioned at and is provided with passage position inwall, and the switching that is attached thereto handle passes from the Y-piece top.
Can be divided into different size according to the diameter of its breather 1 and this trachea of length and bronchus dual-purpose conduit.
Following 1/3rd places of described endotracheal tube between two inflatable cuff are tiny gradually, to adapt to the bronchus size.
Trachea described in the utility model and bronchus dual-purpose conduit are inserted in patient's the bronchus by the doctor in use, fill up corresponding cover capsule, adjust to switch sleeve pipe, connect respirator or anesthetic machine and get final product.
Trachea described in the utility model and bronchus dual-purpose conduit, not only can realize one-lung ventilation, and can work as common endotracheal tube and use, also can be used for the bronchus ventilation, the doctor does not worry the orientation problem of conduit, as long as fill up the aeration status that different cover capsules can be realized performing the operation to be needed.So not only make things convenient for doctor's operation, also reduced patient's danger coefficient and the damage that brings to patient of intubate repeatedly.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
