Description

Three-cavity double-balloon bronchial catheter

Technical Field

The utility model relates to a three-cavity double-balloon bronchial catheter, which belongs to the field of bronchial medical instruments.

Background

The hemorrhage caused in the bronchoscope examination and treatment process is the most main complication of bronchoscope diagnosis and treatment operation, the airway blockage and asphyxiation caused by the large hemorrhage are the most main reasons for death of patients, the key factors for successfully treating and treating the patients are to keep healthy side airways smooth and stop bleeding quickly, the curative effect is usually poor for the more acute and larger hemorrhage only by methods of locally pouring hemostatic drugs, infusing the hemostatic drugs into veins and the like, and therefore, the bleeding bronchus is often required to be plugged and stopped by inserting an airway balloon through a bronchoscope working duct. The existing problem is that the mucosa is necrotized due to overlong filling time of the saccule, the possibility of displacement and separation can occur when pressure is intermittently released, if the saccule is displaced and separated, the hemostasis effect is greatly reduced, even the treatment fails, in addition, the existing catheter is only a single saccule, and the main airway at the healthy side cannot be plugged at the same time, so that the blood of a patient flows to the healthy side.

In view of the problems existing in the prior art, the utility model discloses combine many years' design and experience of use in relevant field, assisted by too strong professional knowledge, designed and manufactured three chamber double-balloon bronchial tubes, overcome above-mentioned defect.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model provides a pair of three chamber double-balloon bronchial tubes, patient suffer from the healthy side of side blood flow direction when can effectively prevent the heavy bleeding, are particularly useful for the requirement that different positions suffer from the side.

In order to realize the purpose, the utility model discloses a technical scheme as follows: a three-cavity double-balloon bronchial catheter comprises an insertion tube and a sleeve sleeved on the insertion tube, wherein the insertion tube is provided with three sections of tubes, the first section of tube can extend into an affected part, a first balloon is arranged on the first section of tube, the second section of tube can extend into a main bronchus, the third section of tube is arranged outside, the diameters of the first section of tube, the second section of tube and the third section of tube are gradually reduced, and a section of external thread is arranged on the third section of tube;

the sleeve is sleeved on the second section of pipe and the third section of pipe, the sleeve is in threaded connection with the third section of pipe, a second balloon is arranged at the end part of the sleeve, and the diameter of the sleeve when the second balloon contracts is equal to that of the first section of pipe;

the medicine injection cavity is arranged in the insertion tube and penetrates through the insertion tube, a first inflation connecting pipe communicated with the first balloon is arranged in the insertion tube, and a second inflation connecting pipe communicated with the second balloon is arranged in the sleeve.

Preferably, a transition surface is arranged between the first section of pipe and the second section of pipe.

As a preferable technical scheme, the end part of the sleeve is provided with a matching surface matched with the transition surface.

As a preferable technical scheme, a sealing ring is arranged between the end part of the sleeve and the second section of pipe, and the sealing ring is fixedly arranged on the inner wall of the sleeve.

The utility model discloses an useful part is:

1. the utility model discloses an utilize the sleeve pipe to remove on the intubate, and then realized the adjustment of second sacculus position, thereby guaranteed that different patients suffer from the demand that the side is different apart from main tributary trachea position (set up the second sacculus at the main tributary trachea not only prevented that the heavy bleeding from getting into healthy side, because the main tributary trachea can bear great sacculus power of expanding equally, thereby guarantee that sufficient sacculus stops the power, and the sleeve pipe box establishes on second section pipe, and sleeve pipe diameter when the sacculus shrink equals first section pipe diameter, guaranteed that the intubate when alternating, the tractive can not appear with the bronchus wall in the sleeve pipe.

2. The utility model discloses the intubate is when alternating, and the shrink of second sacculus, and makes sleeve pipe fitting surface and transition face contact for sleeve pipe and first section pipe coincidence have avoided sleeve pipe and bronchus wall to produce the tractive.

3. The utility model discloses sheathed tube removal utilizes and realizes with third section pipe threaded connection, and then has realized the adjustment of second sacculus position, and the adjustment position is accurate moreover, easy operation.

Detailed Description

The present invention is further described below to facilitate understanding by those skilled in the art.

As shown in fig. 1 and fig. 2, a three-cavity double-balloon bronchial catheter comprises an insertion tube and a sleeve 4 sleeved on the insertion tube, wherein the insertion tube is designed into a three-section tube, a first section of tube 1 can extend into an affected part, a first balloon 5 is arranged on the first section of tube 1 so as to plug a bleeding bronchus to stop bleeding, a second section of tube 2 can extend into a main bronchus, and a third section of tube 3 is arranged outside, the diameters of the first section of tube 1, the second section of tube 2 and the third section of tube 3 are gradually reduced, and a section of external thread 10 is arranged on the third section of tube 3;
