The utility model provides a low damage endotracheal tube core, simple structure, low in manufacturing cost is honest and clean, can alleviate the air flue damage when leading endotracheal tube to put into smoothly.
Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to low damage trachea catheter core.
Background
The use of endotracheal tubes for endotracheal intubation is a necessary means for establishing artificial airways for surgical procedures and for emergency/critical care patients. Because the prior tracheal catheter for performing the endotracheal intubation is made of soft plastics and does not have good plasticity, a metal wire catheter core which has plasticity and is sealed and wrapped by medical plastics is required to be inserted into a lumen of the tracheal catheter to provide good plasticity for the tracheal catheter when in use.
The current tracheal catheter cores mainly comprise the following components: 1. the tube body of the tube core is made of naked hard copper wires or iron wires, and if the tube body exceeds the front end of the tracheal catheter, the tube body can cause the damage of the air passage when the tracheal catheter is inserted. 2. The conduit core is formed by wrapping a layer of plastic by a hard copper wire or iron wire, when the conduit core is placed into the tracheal catheter, the front end of the conduit core needs to be bent into a fishhook shape, so that the conduit core is not easy to deform and is easy to cause air passage scratch. 3. The visual trachea catheter core has a complex structure, comprises a camera, a display screen, a camera connecting wire and the like, is very high in cost and is not suitable for market popularization.
SUMMERY OF THE UTILITY MODEL
In order to compensate the defects existing in the prior art, the utility model provides a low-damage tracheal catheter core, which has simple structure and low manufacturing cost and can lighten the damage of the airway when the tracheal catheter is smoothly guided to be put into.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a low-damage trachea catheter core comprises a catheter core main body made of an aluminum alloy material, wherein a coaxial guide wire with the length of 1.5-2.5cm extends out of one end of the catheter core main body, the diameter of the guide wire is smaller than that of the catheter core main body, and a silica gel layer wraps the guide wire.
Further, the tube core main part and the guide wire are arranged in a hollow mode, silica gel is filled in the tube core main part and the guide wire, an indicator lamp is arranged at the end portion of the guide wire, a power supply unit is arranged at the end portion of the tube core main part, and a lead connected with the indicator lamp and the power supply unit is arranged in the tube core main part.
Further, the power supply unit comprises a micro battery arranged in the tube core main body and a switch arranged on the outer wall of the tube core main body.
Compared with the prior art, the utility model discloses following beneficial technological effect has:
(1) the low-damage tracheal catheter core of the utility model adopts the aluminum alloy as the main body, ensures the integral hardness of the catheter core and can be freely inserted into the tracheal catheter; the silk layer has been wrapped up to the seal wire that extends, and the entering trachea that can the low damage is intraductal, for putting into smoothly of endotracheal tube and play the guide effect, the success rate of guarantee intubate.
(2) The utility model discloses a low damage trachea catheter core is equipped with the pilot lamp, can look directly at through the light guide and judge whether the catheter core is in the trachea, ensures the success rate of intubate.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be embodied in many other forms without departing from the spirit or essential characteristics thereof, and it should be understood that the invention is not limited to the specific embodiments disclosed below.
Example 1
As shown in FIG. 1, a low-damage trachea catheter core comprises a solid core body 1 made of aluminum alloy, wherein a coaxial guide wire 2 with the length of 1.5-2.5cm extends out of one end of the core body 1, and the length of the guide wire 2 is preferably 2 cm. The diameter of the guide wire 2 is smaller than that of the tube core main body 1, and the guide wire 2 is wrapped by a silica gel layer 3. To the patient of intubate difficulty, in using earlier 2 one ends of seal wire of pipe core put into the trachea, can alleviate the air flue damage, rethread pipe core main part 1 guide is put into the trachea with endotracheal tube, can ensure the success rate of intubate.
Example 2
As shown in fig. 2, the low-damage trachea catheter core comprises a hollow aluminum alloy catheter core body 1, wherein a coaxial guide wire 2 with the length of 1.5-2.5cm extends out of one end of the catheter core body 1, and the guide wire 2 is arranged in a hollow mode and preferably has the length of 2 cm. The diameter of the guide wire 2 is smaller than that of the tube core main body 1, and the guide wire 2 is wrapped by a silica gel layer 3. The tube core main body 1 and the guide wire 2 are filled with silica gel 4. The end of the guide wire 2 is provided with an indicator lamp 5, the end of the tube core main body 1 is provided with a power supply unit, and the power supply unit comprises a micro battery 6 arranged in the tube core main body 1 and a switch 7 arranged on the outer wall of the tube core main body 1. The tube core main body 1 is internally provided with a lead 8 for connecting the indicator light 5 and the micro battery 6. When the trachea cannula is used, the indicator lamp 5 can be lightened by turning on the switch 7, and whether the catheter core is in the trachea can be judged directly through light guidance, so that the success rate of the intubation is improved.
Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements and the like can be made in the technical solutions of the foregoing embodiments or in some technical features of the foregoing embodiments, but all modifications, equivalents, improvements and the like within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
