Abstract

The utility model discloses a multifunctional tracheal catheter. The air supply tube is arranged in the air supply tube, the front end of the air supply tube is provided with a respirator connector, the inner wall of the air supply tube is additionally provided with a thin catheter, the thin catheter is connected with an infusion catheter, and the infusion catheter is provided with a connector. The utility model discloses an increase a thin pipe on the inner wall for the trachea to can carry out the intratracheal continuous fluid infusion of trachea, intratracheal atomizing and low concentration to the patient through this thin pipe and give oxygen, make sick and dangerous patient obtain timely effectual treatment, have convenient, swift, safe advantage.

Description

Multifunctional trachea catheter

This utility model relates to a kind of endotracheal tube, belongs to medical apparatus and instruments.

At present the domestic and international endotracheal tube of producing as shown in Figure 1, is used for connecing respirator or oxygen to trachea by forming for trachea and gas tube, and gas tube is used for inflatable cuff inflated and prevents to leak gas from person's windpipe.There is following shortcoming in this endotracheal tube in rescuing the critical patient process: 1, when supspending ventilation during administration in the trachea, from give trachea, put in poison, because a part of medicine (or is having under the situation of breathing adhering on the tube wall, a part medicine with expiration along moving on the endotracheal tube inwall), so just under the dosage condition of limited, the actual dose that arrives tracheal mucosa is difficult to estimation, and the accurate dosage of medication is difficult to guarantee that influence is to patient's rescue quality; 2, under the situation of endotracheal tube connection respirator, just can't continue administration in the trachea, and have the patient under the situation of autonomous respiration, when continuing oxygen supply, Oxygen tube need be inserted in the trachea, Oxygen tube is difficult for fixing on the one hand, and Oxygen tube can take the area in the conduit on the other hand.

The purpose of this utility model is exactly the shortcoming that overcomes prior art, and a kind of multifunctional trachea catheter is provided.

The purpose of this utility model is achieved in that multifunctional trachea catheter is by forming for trachea, gas tube, inflatable cuff, gas tube is in giving trachea, the respiratory organ joint is housed for the front end of trachea, giving fine duct of increase on the inwall of trachea, be embedded with transfusion catheter on the fine duct, transfusion catheter is provided with the transfusion catheter joint.

This utility model is by giving fine duct of increase on the inwall of trachea; thereby can carry out continuing in the trachea atomizing and low concentration oxygen supply in fluid infusion, the trachea to the patient by this root fine duct; the quantity, the concentration that guarantee administration in the trachea reach pre-metering; the patient that is critically ill is treated timely and effectively, have convenient, fast, safe advantage.

Below in conjunction with accompanying drawing this utility model is described further:

Fig. 1: existing endotracheal tube structural representation;

Fig. 2: this utility model structural representation;

Fig. 3: I portion enlarged drawing; Fig. 4: A-A cutaway view; Fig. 5: II portion enlarged drawing;

Among the figure: 1-respiratory organ joint, 2-give trachea, 3-gas tube, 4-gas-charging connection, 5-inflatable cuff, 6-fine duct, 7-transfusion catheter, 8-transfusion catheter joint;

As shown in Figure 2, multifunctional trachea catheter is by forming for trachea 2, gas tube 3, gas tube 3 is in giving trachea 2, at the front end of giving trachea 2 respiratory organ joint 1 is housed, be provided with inflatable cuff 5 in the bottom of giving trachea 2, have the hole facing on the position of inflatable cuff 5 on the gas tube 3, as shown in Figure 5, be used for inflation inflatable cuff 5.For the ease of being carried out, the patient continues atomizing and low concentration oxygen supply in fluid infusion, the trachea in the trachea, the fine duct 6 of making a diameter 1.5mm in the tube wall of trachea 2 of giving at existing endotracheal tube, the transfusion catheter 7 (promptly not being with the syringe needle tube for transfusion) of internal diameter 1mm is embedded in it, shown in Fig. 3,4, it is corresponding with the embedding position of gas tube 3 to embed the position, thus interior blank pipe of sealing tube wall and being communicated with to trachea 2 collar extensions.Joint 8 is equipped with in the outer end of transfusion catheter 7, and it links to each other with the three way cock who has switch, with switch opens, otherwise closes during use, with anti-gas-leak.When needs carry out in the trachea continuing in fluid infusion, the trachea atomizing and low concentration oxygen supply to the patient, as long as connect transfusion catheter 7, open switch and can operate, have advantage easily and efficiently, help patient's relief.

Claims

1, a kind of multifunctional trachea catheter is by forming for trachea (2), gas tube (3), inflatable cuff (5), gas tube (3) is in giving trachea (2), respiratory organ joint (1) is housed for the front end of trachea (2), it is characterized in that: giving an increase fine duct (6) on the inwall of trachea (2), be embedded with transfusion catheter (7) on the fine duct (6), transfusion catheter (7) is provided with transfusion catheter joint (8).
