Description

Two-way administration tracheal catheter for anesthesia

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a tracheal tube is dosed with two routes to anesthesia.

Background

The medicine is administered in the trachea by a doctor in an anesthesia department, the respiration needs to be suspended, the medicine is administered in the trachea catheter, the medicine is easy to adhere to the inner wall of the trachea catheter, and particularly when the medicine with less capacity is administered, the medicine is difficult to enter the trachea to play the medicine role in time and rapidly, and the medicine administration is not accurate.

There are currently two types of endotracheal tubes for administration: one is on the market, it only has a route to administer, it is located the below of gas cell to go out the medicine mouth, gas cell and trachea wall attachment department and gas cell top trachea are difficult for contacting the medicine, another kind has two routes to add the medicine mouth, but it is unreasonable to go out the medicine mouth design, constitute by two gas cells, it is located between inside and outside two sacculums to go out the medicine mouth, the interior sacculus is aerifyd big enough, just can produce sufficient resistance, separate upper and lower medicine, sacculus pressure can cause the medicine to the trachea greatly, and it is the state of spilling over to go out the medicine, can not reach the effect of atomizing spraying.

CN207085041U, Chinese patent "A two-channel administration tracheal catheter for anesthesia", discloses that one end of the tracheal catheter is provided with an anesthesia machine breathing loop interface, the other end is provided with an inflatable balloon, the inflatable balloon is connected with one end of an inflatable balloon tube, the upper end and the lower end of the inflatable balloon are respectively provided with a first administration small balloon and a second administration small balloon, the first administration small balloon and the second administration small balloon are internally provided with an inner tracheal wall channel opening and are respectively connected with a first administration channel and a second administration channel through the inner tracheal wall channel opening, and the other end of the tracheal catheter is uniformly provided with a plurality of small side holes. By adopting two independent administration paths, an anesthesiologist can adopt upper and lower separate administration or upper and lower simultaneous administration, and the administration mode is flexible, but has the following defects:

when dosing simultaneously from top to bottom, need two infusion pumps of doctor's both hands handheld simultaneously to administer, because when pushing the infusion pump, need one hand to hold the infusion pump, one hand promotes the piston rod and injects, obviously one-hand operation is inconvenient, and two infusion pumps of the unable simultaneous of bimanualness are dosed again.

Therefore, how to solve the above problems becomes a focus of research by those skilled in the art.
