Description

Wall-attached bronchial occluder combined with tracheal tube

technical field

The utility model belongs to the technical field of medical mechanical equipment design, in particular to a wall-attached bronchial occluder combined with a tracheal catheter.

Background technique

An occluder is a commonly used medical device for closing one side of the lung for ventilation when patients undergoing thoracic surgery are undergoing one-lung ventilation. Currently, bronchial occluders are often used in combination with single-lumen endotracheal tubes. The basic structure of the bronchial occluder in the prior art includes an inflatable structure, a sleeve and a balloon. In actual operation, the bronchial occluder is inserted into the ventilation lumen of the tracheal tube, and then used in the fiberoptic bronchoscope. The balloon of the bronchial occluder is inserted into the bronchus of the target side under the guidance, and the balloon is inflated, so that the balloon of the bronchial occluder blocks the bronchus of the target side and collapses the lung of the target side, which helps to expand the surgical field of vision. , so that the surgeon can observe the diseased organ more clearly, which is beneficial to the operation of the operation. However, for infants or young children, the inner diameter of the ventilation lumen of the tracheal tube is too small to place a bronchial occluder in the tracheal tube, and it is not conducive to special operations such as sputum suction. An external endotracheal bronchial occluder can be an effective option at this time.

However, there are still many problems with the use of external bronchial occluders. For example, the current way of placing bronchial occluders outside the trachea requires the use of adhesive tape to fix the position of the external tracheal occluder. If the occluder needs to be temporarily replaced or adjusted There are many inconveniences in the location. If the external bronchial occluder fixed with tape is not firmly fixed, it is easy to shift, especially during the surgical positioning process, the bronchial occluder that is not firmly fixed is more likely to shift. This will not only lead to changes in a series of respiratory parameters such as changes in ventilation, increased airway pressure, and increased end-tidal carbon dioxide, but also the blood oxygen saturation will drop immediately. risk factors.

In some related technologies, based on the aforementioned problems, there is also a way of disposing the related bronchial occluder on the outside of the tracheal tube, so that it no longer occupies the inner space of the ventilation lumen, but this way of being on the outside of the tracheal tube has some diseases. There is a hidden danger of tracheal injury, and this method also has many shortcomings in the positioning of the bronchial occluder.

Detailed ways

Referring to FIG. 1 , according to an embodiment of the present invention, a wall-attached bronchial occluder combined with a tracheal tube is provided, including a tracheal tube 1 , the tracheal tube 1 has a main ventilation lumen 11 , and the trachea The tube wall of the catheter 1 is constructed with a channel extending along its length direction, and a bronchial blocking component is inserted into the channel. The blocking member can slide along the length of the endotracheal tube 1 in the channel under the control of the operator, for example, by pushing and pulling the bronchial blocking member inside and outside the operator, so as to adjust the position of the bronchial blocking member . In this technical solution, the occluder main body 21 of the bronchial occluder is located in the channel constructed in the tube wall, which maintains the smoothness of the outer peripheral side of the tracheal tube 1, and effectively prevents the bronchial occluder from possibly damaging the trachea of the patient. And the channel wall of the channel can effectively limit the occluder main body 21, so that the occluder main body 21 only has the possibility of sliding along its length extending direction, which is more convenient to fix the bronchial occluder; Compared with the arrangement in which the bronchial blocking member passes through the main ventilation lumen 11 in the technology, the bronchial blocking member is slidably connected to the tube wall of the tracheal tube 1 and no longer occupies the internal space of the main ventilation lumen 11, which is especially suitable for the main ventilation lumen 11. When the inner diameter of the ventilation lumen 11 is small, the endotracheal placement can be completed with a single tracheal intubation, and then all operations can be completed by simply sliding the bronchial blocking components back and forth. In the single-lung ventilation of infants and young children, it has The obvious advantage is that it can make full use of lumen ventilation, which is convenient for endotracheal operations such as sputum suction, and the occluder is firmly fixed, which can fully ensure the safety of patients. Operate sputum suction to ensure the safety of patients.

In some embodiments, the bronchial occlusion component further includes an occluder indicating balloon 23, the occluder body 21 has an internal segment that can be placed inside the patient's body and an extracorporeal segment that can be placed outside the patient's body. The occlusion balloon 22 is located on the inner body segment, and the occluder indicating balloon 23 is located on the outer segment, so that the occlusion balloon 22 can be predicted by observing the occlusion device indicating the fullness of the balloon 23. , as a basis for whether the operator's inflation is sufficient.

It should be noted that the channel in the tube wall of the endotracheal tube 1 should be a continuous channel, and the basic principle is that the push-pull operation of the occluder body 21 is not hindered. When the tracheal tube 1 is folded, a certain space should be provided between the channel and the main body 21 of the occluder so as not to damage the structure of the occluder.

The occluder balloon 22 is made of a flexible and fully resilient material, so that it can be retracted into the channel of the tube wall after being deflated. Since the occluder balloon 22 can be retracted into the channel after being deflated (deflated), damage to the patient's trachea during tracheal intubation can be avoided.

In some embodiments, the occluder head end 26 includes the occluder head end 26 on the side of the occlusion balloon 22 close to the patient's body, and the overall length of the occluder head end 26 may be approximately 5-10 cm. A corresponding 5-10 cm section to be able to accommodate this part. The head end 26 of the occluder (including the occlusion balloon 22 ) is flexible to ensure that it can be angled and maintained so as to facilitate entry into the branch bronchus.

In some embodiments, the occluder indicating balloon 23 communicates with the occluding balloon 22 through the occluder inflation conduit 24, and an occluder is provided at the air inlet of the occluder indicating balloon 23 One-way valve 25 to prevent air bag from leaking.

In some embodiments, the tracheal tube 1 has an internal end that can be placed inside the patient and an external end that can be placed outside the patient. The external end is provided with a tracheal tube connector 12 on which A fixing structure 13 is constructed, and the part of the external section of the occluder body 21 outside the passage can be fixed integrally with the tracheal tube connector 12 through the fixing structure 13 . In this technical solution, the bronchial blocking member whose position has been adjusted can be positioned by the fixing structure 13, so as to prevent the bronchial blocking member from sliding up and down and causing potential safety hazards after blocking.

As a specific implementation manner, the fixing structure 13 has a slot, and the occluder body 21 can be embedded in the slot to realize the blocking of the slot by the slot by its own deformation. The clamping of the main body 21 of the device is simple, reliable, and easy to operate.

In some embodiments, a tracheal cuff 14 is provided on the tube wall of the tracheal tube 1 , and the tracheal cuff 14 can be inflated and deflated in a controllable manner. The design of the tracheal cuff 14 can ensure that the trachea The catheter 1 can be stably and reliably placed in the trachea of the patient after the intubation is in place.

In some embodiments, the wall-attached bronchial occluder combined with the tracheal tube further comprises a tracheal tube indicator balloon 15 , and the tracheal tube indicator balloon 15 communicates with the tracheal cuff 14 through a tracheal inflation tube 16 , a tracheal tube one-way valve 17 is provided at the air inlet of the tracheal tube indicating balloon 15 .
