Description

Expandable cannula

Technical Field

The utility model relates to a medical intubate technical field especially relates to an expandable intubate.

Background

The intubation tube is a product commonly used in the medical field, and when the intubation tube is used, an operator inserts the catheter into a human body through the body surface and the inner cavity of the human body so as to input and suck out gas or liquid.

At present, the common trachea cannula is the trachea cannula that is produced by high elastic force PVC and medical stainless steel wire inside lining, and the trachea cannula of this type has the problem that can't adjust the external diameter, leads to the art when performing the operation wild.

Disclosure of Invention

The embodiment of the utility model provides an expandable cannula can effectively expand operation position, provides better art field, and the overall operation is comparatively simple and convenient.

To achieve the above objects, embodiments of the present invention provide an expandable cannula, including a tube, a first balloon and a second balloon;

the pipe body comprises a handheld end and an inlet end;

the first air bag is arranged at the inlet end, the second air bag is arranged at the handheld end, an air pipe for communicating the first air bag with the second air bag is arranged on the pipe body, and the second air bag is connected with an inflatable air bag.

Compared with the prior art, the utility model discloses an expansible intubate carries out the technical scheme that expands to the blood vessel through first gasbag inflation, has solved prior art trachea cannula and has had unable regulation external diameter, and the art is wild when leading to performing the operation is unclear problem, has obtained and can effectively expand the operation position, provides better art wild, and the overall operation is comparatively simple and convenient beneficial effect.

As an improvement of the scheme, the second air bag is sleeved with an indication layer imitating the elasticity of the inner wall of the tissue.

As an improvement of the scheme, the indicating layer is sleeved outside the second air bag in an interference fit manner.

As an improvement of the scheme, an inflation connecting port is arranged on the inflation air bag.

As an improvement of the scheme, the air pipe is attached to the outer side of the pipe body.

The method has the following specific beneficial effects:

1. the information that the operator fed back is more accurate, and when carrying out the operation, the operator can know the elasticity of patient treatment position blood vessel in advance, according to the information that reachs, utilizes 3D printing or other techniques imitation to produce the instruction layer that the elasticity is similar. When the operation is carried out, the expansion environment of the first air bag is almost the same as that of the second air bag at the treatment part, so that the information fed back to an operator is more accurate;

2. the dismouting of instruction layer is comparatively convenient, and outside the instruction layer was interference fit cover and locates the second gasbag, can be convenient for the operator installation dismantlement.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It is to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The terms "comprises" and "comprising" indicate the presence of the described features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The term "and/or" refers to and includes any and all possible combinations of one or more of the associated listed items.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of a specific structure of an embodiment of the present invention, and fig. 2 is an internal structure diagram of an embodiment of the present invention.

An expandable cannula includes a tubular body 1, a first balloon 2 and a second balloon 3. The body includes a hand-held end 4 and an inlet end 5.

The first air bag 2 is fixedly arranged at the body end 5, the second air bag 3 is fixedly arranged at the handheld end 4, an air pipe 6 for communicating the first air bag 2 with the second air bag 3 is fixedly arranged on the pipe wall of the pipe body 1, and the second air bag 3 is connected with an inflatable air bag 7. The air tube 6 is attached to the outside of the tube body 1.

When carrying out the operation, the operator inserts the human body and leads to the operation position back with the intubate, if the art field is not clear enough, the gasbag 7 is aerifyd in the accessible pressing, aerifys to first gasbag 2, and first gasbag 2 will expand gradually when aerifing, treats the art field clear back, can stop to aerify, continues to perform the operation. The operation of the expansion of first gasbag 2 is comparatively simple and convenient, and the operator only need control the handheld end 4 of body 1 and press inflatable air bag 7, can adjust the art field.

In this embodiment, an inflation connection port is provided in the inflatable airbag 7, and an inflation device can be connected to the inflation connection port when it is not convenient to press the inflatable airbag 7 if the hand is insufficient during the operation.

When adjusting the art field, will oppress blood vessel or tracheal inner wall because of the inflation of first gasbag 2, blood vessel or tracheal inner wall have certain elasticity, can not harm it in appropriate within range, in order to let the synchronous inflation condition of knowing first gasbag 2 of operator, the event sets up the communicating second gasbag 3 with first gasbag 2 atmospheric pressure at handheld end 4 of body, so when pressing inflatable air bag 7, first gasbag 2 will expand with second gasbag 3 in step, the operator can be according to the inflation degree of second gasbag 3, the compelled degree of blood vessel or tracheal inner wall to the operation position is judged, the operation of intubate uses the transparency greatly, for the inside message of operator's synchronous feedback treatment position, bring superior practicality for this product.

More preferably, the second air bag 3 is sleeved with an indication layer 8 simulating the elasticity of the inner wall of the tissue. The elasticity of the indication layer 8 is similar to that of the blood vessel of the treatment part, and when the operation is performed, an operator can know the elasticity of the blood vessel of the treatment part of the patient in advance, and the indication layer with the similar elasticity is imitated by 3D printing or other technologies according to the obtained information.

In cooperation with the upper indication layer 8, the expansion environment of the first air bag 2 is almost the same as that of the second air bag 3 at the treatment part during the operation, so that the information fed back to the operator is more accurate.

More preferably, the indication layer 8 is sleeved outside the second airbag 3 in an interference fit manner, and through the arrangement, the indication layer 8 can be conveniently mounted and dismounted by an operator.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
