Abstract
The double-cavity bronchial cannula capable of realizing single-lung ventilation comprises a cannula body, wherein the cannula is provided with a four-way connecting pipe, and valves are arranged on two branch pipes of the four-way connecting pipe. The utility model is used for solve current two-chamber trachea cannula and block the inconvenient and easy problem that leaks gas of operation.
Description
Technical Field
The utility model relates to the field of medical equipment, more specifically relates to a two-chamber trachea cannula that can realize single lung ventilates.
Background
The double lumen pipe on the existing market takes root in the operation according to the needs, the external connecting pipe of the operation side is closed by the operation forceps, the lung respiration of the operation side is blocked, whether the effect of closing the ventilation is achieved or not needs to be repeatedly confirmed in the use process, the operation is not only inconvenient, the weight of the connecting pipe can be increased by adding the operation forceps on the external connecting pipe, if the operation forceps are not clamped tightly, the life safety of a patient can be endangered, and the risk in the process of the anesthesia operation is increased.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a two-chamber trachea cannula that can realize single lung to ventilate for solve current two-chamber trachea cannula and block the inconvenient problem that leaks gas easily of operation.
In order to solve the above problem, the to-be-solved technical scheme of the utility model is:
the double-cavity bronchial cannula capable of realizing single-lung ventilation comprises a cannula body, wherein the cannula is provided with a four-way connecting pipe, and valves are arranged on two branch pipes of the four-way connecting pipe.
Two valves on the two branch pipes are arranged in a staggered manner.
The two valves are arranged in a circular shape.
The valve is provided with a current limit part, the limit part comprises an end cover connected to one end of a valve core of the valve, one end of the valve body is arranged in the end cover, at least one arc-shaped groove is formed in the end cover, a limit block is arranged in the arc-shaped groove, and the limit block is fixedly connected with the valve body.
And the end covers at the two ends of the arc-shaped groove are respectively provided with a marking line for indicating the opening and closing direction of the valve core.
The technical effects of the utility model are that: this novel in design is reasonable, installs a breather valve on the four-way connection pipe. The doctor can control the effect of single lung ventilation through rotatory ventilation valve, and the valve shape is circular, and the setting of this shape can reduce because of the operation risk that the artificial collision caused the valve to remove and bring in the operation. The setting of spacing groove and stopper can make the doctor screw up the valve to the assigned position fast and accurately to realize the unipneumon of arbitrary one side fast and ventilate, convenient operation, and the security is high. The structure is reliable and stable, and the hidden danger of air leakage caused by the fact that the valve is not screwed into place can be eliminated.
Drawings
The invention will be further explained with reference to the drawings:
FIG. 1 is a schematic view of the front view structure of the present invention,
FIG. 2 is a schematic side view of the present invention,
figure 3 is a schematic perspective view of the valve of the present invention,
fig. 4 is a schematic sectional view of the valve according to the present invention.
In the figure: the valve comprises an insertion pipe 1, a valve 2, a valve body 21, an end cover 22, an arc-shaped groove 23, a limiting block 24, a marking line 25, a valve core 26, a four-way connecting pipe 3 and a branch pipe 31.
Detailed Description
As shown in fig. 1 to 4, the double-lumen bronchial cannula capable of achieving single lung ventilation includes a cannula 1 body, the cannula 1 has a four-way connection tube 3, and valves 2 are mounted on two branch tubes 31 of the four-way connection tube 3.
The doctor can be through the effect that the single lung of rotatory vent valve 2 control ventilates, convenient operation, and the security is high. Furthermore, a doctor can directly screw the valve to the maximum distance position where the limiting block can slide on the limiting groove in a further-in-place mode, so that the effect that the single lung ventilates without air leakage in an operation is quickly and accurately achieved, the risk of air leakage caused by the fact that the valve is not screwed down due to human factors is reduced, the structure is reliable and stable, and the hidden danger of air leakage can be eliminated.
The two valves 2 on the two branch pipes 31 are arranged in a staggered mode. The structure can ensure that the opening and the closing of the two valves 2 are not interfered with each other, thereby being convenient for doctors to operate.
The two valves 2 are provided in the shape of a circle. Compared with a handle type valve, the round valve 2 can reduce the probability of misoperation.
The valve 2 is provided with a conventional limiting part, the limiting part comprises an end cover 22 connected to one end of a valve core 26 of the valve 2, one end of a valve body 21 is arranged in the end cover 22, at least one arc-shaped groove 23 is formed in the end cover 22, a limiting block 24 is arranged in the arc-shaped groove 23, the limiting block 24 is fixedly connected with the valve body 21, and the limiting block 24 can slide in the limiting groove 23 according to a fixed track of the groove.
When a doctor conducts unilung ventilation, the valve 2 needs to be twisted to a specific position, and a slight deviation can prevent the tracheal cannula 1 on the side from completely blocking the gas transmitted by a respirator. Therefore, the valve cover is provided with the arc-shaped groove 23 and the limiting block 24, when a doctor twists the limiting block 24 of the valve 2 to abut against one end of the arc-shaped groove 23, the doctor can obviously feel the blocking feeling and knows that the valve is twisted to the position, so that the valve is more convenient to operate.
And a marking line 25 for indicating the opening and closing direction of the valve core 26 is respectively arranged on the end covers 22 at the two ends of the arc-shaped groove 23. This configuration facilitates the doctor to observe the open and close position of the valve 2.
