Abstract
The utility model relates to a double air bag tracheal catheter. The two air bags are arranged at the front end of the tracheal catheter and wrap the tracheal catheter, and the air bags are connected with a connecting tube and an air bag observing bag. The utility model is characterized in that the two air bags are connected together trough each connecting tube and air bag observing bag respectively.
Description
Technical field
The utility model is a kind of medical treatment device, is mainly used in anaesthetizing the mechanical ventilation with the urgent patient, can reduce cuff to the damage of tracheal mucosa.
Background technology
By the tracheal catheter important means that to carry out mechanical ventilation be in the operation and patients after surgery is supported, some urgent patient even need Long Term Mechanical Ventilation; Used tracheal catheter is single cover ductus bursae at present, and cuff is inflated for a long time and can be continued the compressing tracheal mucosa, causes the major injury of tracheal mucosa, even downright bad perforation.For the patient that Long Term Mechanical Ventilation is supported, adopt and be interrupted cuff venting (as every a few hours venting 5 minutes) the efficient recovery district's tracheal mucosa blood perfusion that suffers oppression can not be arranged, and this method may cause that patient mistake takes place inhale; Can not allow the cuff venting for going the patient of mechanical ventilation.
Summary of the invention:
The damage that the lasting compressing of tracheal mucosa is caused in order to overcome present used single cuff tracheal catheter, the utility model provides a kind of double cuff tracheal catheter, and this device can reduce behind the sleeve bag gas-filling damage to tracheal mucosa.
The technical scheme that its technical problem that solves the utility model adopts is: settle two cuffs in the tracheal catheter distal outer, can inflate through separately tube connector and cuff observation capsule respectively.This double cuff tracheal catheter is that 1.2-2cm does not wait according to catheter diameter with the cuff Design of length, all is positioned at the tracheal catheter far-end, and two cuff middle wares are apart from 0.5cm.
The beneficial effects of the utility model are: double cuff can alternately be inflated, thus the infringement of having avoided behind the single sleeve bag gas-filling the lasting compressing to tracheal mucosa to cause; Prevent the mistake suction that the cuff venting causes.
Description of drawings
Fig. 1 is a front elevation, and Fig. 2 is a side view.
Among the figure, 1, the first cover capsule; 2, the second cover capsules; 3, the second cover capsule connection tubes; 4, the second cover capsules are observed capsule; 5, the first cover capsule connection tubes; 6, the first cover capsules are observed capsule; 7, endotracheal tube.
The specific embodiment
Consult Fig. 1, the first cover capsule (1) and the second cover capsule (2) all are positioned at endotracheal tube (7) front end outside and hold endotracheal tube, and the first cover capsule (1) is observed capsule (6) through the first cover capsule connection tube (5) with the first cover capsule and is connected; The second cover capsule (2) is observed capsule (4) through the second cover capsule connection tube (3) with the second cover capsule and is connected.After inflating and keep certain hour, first cuff (1) exits, immediately with second sleeve bag gas-filling, be beneficial to the tracheal mucosa restoration of blood flow that the first set bag pressure is compeled, after second cuff (2) is inflated and kept certain hour, first sleeve bag gas-filling is also exitted second cuff at once, so iterative cycles.
Claims (1)
1 one kinds of double cuff tracheal catheters, two cuffs all are positioned at the tracheal catheter front end and hold tracheal catheter, and cuff and tube connector and cuff are observed capsule and linked to each other, it is characterized in that: two cuffs are connected with cuff observation capsule separately through tube connector separately respectively.
