Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of breathing circuit t-joint, is mainly applicable in ultrasonic Aspiration-needle biopsy art (E-BUS).
Background technology
Ultrasonic Aspiration-needle biopsy art (E-BUS) is current effective detection methods for mediastinum space occupying lesion, for the pathological staging of indulging biopsy, the especially pulmonary carcinoma of diaphragm occupy-place, plays an important role.Along with the raising of sickness rate and the diagnosis of pulmonary carcinoma and mediastinum tumor, such technology has obtained significant progress and has been popularized gradually, and increasing needs of patients carries out E-BUS inspection.
E-BUS checks and normally under intravenous anesthesia, carries out, and after completing tracheal intubation, checks that doctor puts into trachea intracavity by the external passage of tracheal intubation by tracheascope and checks.In operating process, owing to there is no special-purpose external equipment, external equipment need to be carried out to the artificial passage that is applicable to use to reach of processing, in this process, can make tracheal intubation gas leakage affect patient's ventilation, the consequence causing will be the shut-down operation that is interrupted of needs and carry out manual ventilation and reached the oxygenate demand that meets Anesthetic Patients, increase undoubtedly the risk of inspection and the time of operation, be also unfavorable for patient's post-operative recovery simultaneously.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of breathing circuit t-joint, is mainly applicable in ultrasonic Aspiration-needle biopsy art (E-BUS).
The purpose of this utility model is achieved through the following technical solutions:
A kind of breathing circuit t-joint of the present utility model, comprise body, the first pipe joint, the second pipe joint and three way cock, described the first pipe joint is plugged on the first end of described body, described three way cock comprises first interface, the second interface and the 3rd interface, described the second pipe joint is plugged to one by the second end of described first interface and described body, on described the second interface, be provided with attachment cap, it is characterized in that, described attachment cap inner side is provided with one-way valve.
On described the second interface, be also provided with ring for fixing, described attachment cap is connected on described the second interface by described ring for fixing.
Described breathing circuit t-joint, also comprises the 3rd pipe joint, on described the 3rd interface, is plugged with the 3rd pipe joint.
Described body is bellows body.
Described one-way valve and described attachment cap all have interstitial hole, and the diameter of the interstitial hole of one-way valve is less than the diameter of the interstitial hole of described attachment cap, and the diameter of the interstitial hole of one-way valve is greater than the diameter of the conventional ultrasonic endoscope using.

A kind of breathing circuit t-joint of the present utility model can operate smoothly in the situation that not affecting ventilation, and the turnover of tracheascope does not affect patient's ventilation, also can directly carry out manual ventilation where necessary; Operation and patient's oxygenate are not interfere with each other, under the prerequisite that guarantees patient safety, meet the demand checking, improve the positive rate of inspection, for patient's diagnosis and treatment provides support.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of a kind of breathing circuit t-joint of the present utility model;
Fig. 2 is attachment cap in the breathing circuit t-joint in Fig. 1 and the plan structure enlarged diagram of one-way valve.
The specific embodiment
For making this utility model easier to understand, below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for this utility model is described.
Fig. 1 is the structural representation of a preferred embodiment of a kind of breathing circuit t-joint of the present utility model;
A kind of breathing circuit t-joint of the present utility model, comprise body 1, the first pipe joint 21, the second pipe joint 22 and three way cock 3, described the first pipe joint 21 is plugged on the first end 11 of described body 1, described three way cock 3 comprises first interface 31, the second interface 32 and the 3rd interface 33, described the second pipe joint 22 is plugged to one by the second end 12 of described first interface 31 and described body 1, on described the second interface 32, be provided with attachment cap 34, described attachment cap 34 inside arrange one-way valve 35.On described the second interface 32, be also provided with ring for fixing 36, described attachment cap 34 is connected on described the second interface 32 by described ring for fixing 36.The breathing circuit t-joint of the present embodiment also comprises the 3rd pipe joint 23, on described the 3rd interface 33, is plugged with the 3rd pipe joint 23.Described body 1 is bellows body.
Fig. 2 is attachment cap 34 in the breathing circuit t-joint in Fig. 1 and the plan structure enlarged diagram of one-way valve 35.As seen from Figure 2, one-way valve 35 is in the inner side of described attachment cap 34, and described one-way valve 35 all has interstitial hole with attachment cap 34, and the diameter of the interstitial hole 351 of one-way valve 35 is less than the diameter of the interstitial hole 341 of attachment cap 34.The diameter of the interstitial hole 351 of one-way valve 35 is slightly larger than the conventional ultrasonic endoscope using, one-way valve 35 is closed state when not using, one-way valve 35 is prepared by having certain elastoplast, thereby, make mirror ratio be easier to put in by interstitial hole 351, and can guarantee to put into the gas of respirator after mirror and from this hole, do not flow out.
