Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The components of the present invention are all common standard components or components known to those skilled in the art, and the structure and principle thereof can be known to those skilled in the art through technical manuals or through routine experimentation.
Referring to fig. 1 to 3, the present invention provides a technical solution: a guide strip for passing through a blood vessel trachea gap comprises a guide section 1, wherein the guide section 1 is a flexible and transparent strip-shaped structure with the length of 30-40cm, the guide section can be made of natural rubber, silicon rubber or polyvinyl chloride (PVC) to ensure that the guide section can rapidly pass through the blood vessel or trachea gap during working, one end of the guide section 1 is communicated with a first bending section 2, the other end of the guide section 1 is communicated with a second bending section 3, the first bending section 2 and the second bending section 3 are made of polyvinylidene fluoride and have good shaping performance and hardness, the first bending section 2 and the second bending section 3 are transparent, one ends of the first bending section 2 and the second bending section 3, which are far away from the guide section 1, are provided with ultrathin tapered oblique ports 4, the ultrathin tapered oblique ports 4 are made of ultrathin materials, and the inner diameters of the ultrathin tapered oblique ports are 0.5-1.0 cm from small to large, the outer walls of the guide section 1, the first bending section 2, the second bending section 3 and the ultrathin tapered bevel opening 4 are coated with hydrophilic coatings 5, the hydrophilic coatings 5 adopt hydrophilic polymers such as polyethylene glycol, polyvinylpyrrolidone vinyl acetate and the like, the hydrophilic polymers and degradation products of the hydrophilic polymers in a human body are nontoxic, the hydrophilic polymers are coated on the tube wall, a transparent film is formed after drying, and the hydrophilic polymers rapidly expand to form hydrogel after meeting water or blood, so that the high-lubrication effect can be achieved, and the ultrathin tapered bevel opening guide tube is safe to use, sanitary and convenient to operate.
In a preferred embodiment, a plurality of through holes 6 are arranged on the guide section 1 at equal intervals.
Specifically, through-hole 6's setting can be convenient for medical personnel to see through guide section 1 and run through its back condition, and then take corresponding measure fast.
In a preferred embodiment, the outer end of the ultrathin tapered bevel 4 is arranged obliquely.
Particularly, the cutting closer can be conveniently cut into the medical nursing staff through the inclined arrangement, and then the working efficiency of the medical nursing staff is improved.
