Abstract
The utility model belongs to a medical instrument, in particular to a humidifying tracheal sleeve which is used when a critical patient needs a tracheotomy. The humidifying tracheal tube is composed of an intubatton (1), a gasbag (2), a humidifying catheter (10), an aerating catheter (7), a fixed yoke (13) and a fixing strap (12), wherein, a humidifying membrane (4) is arranged on the inner wall of the internal intubatton end (3) of the cannula (1), the humidifying membrane (4) is connected with the humidifying catheter (10), the gasbag (2) takes a spheroid shape after being aerated, the distance between the front end of the gasbag (2) and the internal cannula end (3) is 0.3 cm to 0.5 cm, and the humidifying membrane (4) is made of medical hollow fiber. The humidifying tracheal tube adopts the hollow fiber humidifying membrance, the gasbag (2) takes the spheroid shape after being aerated, and the distance between the front end and the internal intubatton end (3) is 0.3 cm to 0.5 cm, thereby ensuring the inhaled gas to be continuously and uniformly humidified, avoiding the possibility of pulmonary edema, not causing the asphyxia of the patient, and being safe and reliable during use.
Description
Technical field
This utility model belongs to medical apparatus and instruments, a kind of humidifier pipe-in-pipe of using during particularly a kind of crisis needs of patients tracheotomy.
Background technology
At present, clinically, neurosurgery especially, many critical patients need tracheotomy to insert tracheal casing pipe to improve ventilation or connect the respirator assisted respiartion, be the humidifying air, need constantly splash into normal saline.There are following shortcoming in this kind tracheal casing pipe and humidification method: 1, humidification is inhomogeneous.Mainly contain at present and continue drop-method and drop-method dual mode at interval, these two kinds of methods all cause easily and splash into liquid and form current, can not get humidifying and suck gas, and cause in addition that the patient chokes and cough, cause the possibility of pulmonary edema.2, the oversize too pine of the air bag of tracheal casing pipe, attachment area is too short, and the inflation back is cylindrical, and front end surpasses the sleeve pipe internal orifice, easily wraps the tracheal casing pipe internal orifice, causes the patient to suffocate.
Summary of the invention
The purpose of this utility model is design a kind of humidifier pipe-in-pipe a kind of simple in structure, easy to use, safe and reliable.
The purpose of this utility model is achieved in that it is to be provided with humidification membrane at the inwall place of the intubate internal orifice end of the intubate of the tracheal casing pipe that includes intubate, air bag, humidification conduit, inflating catheter, fixed mount and fixing band, humidification membrane and humidification conduit join, behind the airbag aeration at intubate internal orifice place is elliposoidal, and the air bag front end is 0.3～0.5cm apart from intubate internal orifice port.Humidification membrane adopts medical hollow cellulose to make.
This utility model is owing to adopted humidification membrane and be fiber hollow humidification membrane, it is the hollow cellulose film, claim the cellulose hollow fiber film again, be a kind of medical high polymer film that is specifically designed to gas humidification, it is even to have a humidification, is difficult for forming the characteristics of water droplet, its permeability increases along with the increase of gas-liquid interface pressure differential, can reach more than 90% through the gas relative humidity behind the humidification, guarantee that suction gas obtains continuing uniform humidifying, avoid the possibility of pulmonary edema.And because air bag is improved, make the elliposoidal air bag, make the air bag body slightly be shorter than its attached air bag, front end is apart from intubate internal orifice port 0.3-0.5cm, and like this, the inflation rear gasbag is elliposoidal, front end can not exceed the intubate internal orifice, can not cause that the patient suffocates, and is safe and reliable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing: 1-intubate, 2-air bag, 3-intubate internal orifice, 4-humidification membrane, 5-check valve, 6-ballonet, 7-inflating catheter, 8-intubate collar extension, 9-respirator joint, 10-humidification conduit, 11-water filling interface, 12-fixing band, 13-fixed mount.
The specific embodiment
That the utility model is described in further detail is as follows below in conjunction with accompanying drawing:
It is that the inwall place of intubate internal orifice 3 ends of the intubate 1 of the tracheal casing pipe that is made of intubate 1, air bag 2, humidification conduit 10, inflating catheter 7, fixed mount 13 and fixing band 12 is provided with humidification membrane 4 for this utility model, humidification membrane 4 joins with humidification conduit 10, air bag 2 inflation backs apart from intubate internal orifice 3 places are elliposoidal, and air bag 2 front ends are 0.3～0.5cm apart from intubate internal orifice 3 ports.Humidification membrane 4 adopts medical hollow cellulose to make.
This utility model is used convenient: the conventional method tracheotomy, insert tracheal casing pipe, fixing, then normal saline is connected to water filling interface 11 places by transfusion device, continue to splash into and get final product, the permeability of humidification membrane 4 increases along with the increase of gas-liquid interface pressure differential, thereby is scalable gas-liquid interface pressure by the height of regulating infusion bottle, thus the air humidity that obtains suiting.
Claims (3)
1, a kind of humidifier pipe-in-pipe it be to constitute by intubate (1), air bag (2), humidification conduit (10), inflating catheter (7), fixed mount (13) and fixing band (12), it is characterized in that: the inwall place of intubate internal orifice (3) end of intubate (1) is provided with humidification membrane (4), and humidification membrane (4) joins with humidification conduit (10).
2, a kind of humidifier pipe-in-pipe according to claim 1 it is characterized in that described air bag (2) inflation back is elliposoidal, and air bag (2) front end is 0.3～0.5cm apart from intubate internal orifice (3) port.
3, a kind of humidifier pipe-in-pipe according to claim 1 and 2 is characterized in that described humidification membrane (4) adopts medical hollow cellulose to make.
