Furthermore, scales are arranged on the administration catheter and the tracheal catheter, and the positions of the scales on the administration catheter correspond to the positions of the scales on the tracheal catheter.

Furthermore, one end of the administration catheter is also provided with a luer connector; the luer connector is matched with an injection port of the injector.

Preferably, the pipe diameter of the administration catheter is not more than 2.25mm, and the length of the administration catheter is 21-29 cm.

Preferably, the material of the administration catheter is PVC, PP or PUR.

Preferably, the material of the plug is polyethylene or silica gel.

Preferably, the connecting pipeline is made of PVC.

The utility model provides a device of dosing in endotracheal tube has set up connecting tube between breathing machine pipeline and endotracheal tube to set up the opening on connecting tube's lateral wall, the end cap that is equipped with one-way duckbill valve in the opening adoption is sealed. When the medicine is administered in the tracheal catheter for the infant patient, one end of the administration catheter is inserted into the connecting pipeline through the one-way duckbill valve in the plug, and then is inserted into the tracheal catheter to enter the body of the infant patient; the liquid medicine is injected into the administration catheter through one end of the administration catheter positioned outside the connecting pipeline, so that the administration operation is realized. Owing to set up end cap and one-way duckbill valve, consequently, even the catheter of dosing also can keep respiratory tube's airtight state after passing one-way duckbill valve, whole process of dosing can go on under airtight environment promptly, can not influence the normal ventilation of infant. And the whole drug administration process is convenient to operate, and the drug administration difficulty can be reduced. In addition, set up the corresponding scale in position on pipe and the endotracheal tube of dosing, can guarantee to dose the accurate of pipe and insert, and then guarantee that the accuracy of medicine instils into. After the medicine is used, the administration catheter is pulled out, at the moment, the pipeline can still be kept in a closed state due to the effect of the plug one-way valve, the connector is taken down after the illness state of the infant is stable, and the influence of the fact that the breathing pipeline is disconnected when the condition of the infant is not good on ventilation of the infant is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.

Fig. 1 and fig. 2 are schematic structural diagrams of an embodiment of the present invention, including: a connecting pipeline 1 and an administration catheter 2; one end of the connecting pipeline 1 is matched with one end of a breathing machine pipeline, and the other end of the connecting pipeline 1 is matched with one end of a tracheal catheter; when in use, the connecting pipeline is connected between the breathing machine pipeline and the tracheal catheter. Neither the ventilator circuit nor the endotracheal tube is shown in the drawings of the specification. An opening 3 is arranged on the side wall of the connecting pipeline 1; further comprising: a plug 4 adapted to the opening 3, as shown in fig. 3; the plug 4 is made of a soft material; a one-way duckbill valve is arranged in the plug 4; the administration line 2 may be inserted inside the connection tube 1 through the one-way duckbill valve. Due to the arrangement of the plug and the one-way duckbill valve inside the plug, the administration catheter can still keep the closed state of the breathing pipeline after passing through the side wall of the connecting pipeline through the one-way duckbill valve. The one-way duckbill valve of the present embodiment is not different from the prior one-way duckbill valve structure, which is not shown in the drawings of the specification. In order not to affect the ventilation of the sick children, the pipe diameter of the administration catheter 2 is not more than one half of the pipe diameter of the tracheal catheter; in order to realize more accurate dripping of the liquid medicine, the length of the administration catheter 2 is not less than that of the tracheal catheter.

In order to ensure the accurate insertion of the administration catheter and further ensure the further accurate dripping of the medicine, in this embodiment, the administration catheter 2 and the endotracheal tube are both provided with scales, and the positions of the scales on the administration catheter 2 correspond to the positions of the scales on the endotracheal tube. During the use, connect the connecting tube back between breathing machine pipeline and endotracheal tube, the one-way duckbilled valve that will administer the pipe is inserted through end cap 4 in one end of pipe to judge the depth of insertion of pipe of dosing through the scale on pipe of dosing and the endotracheal tube, can make the pipe of dosing unanimous with endotracheal tube's depth of insertion, make it just in time be located the internal carina process top of infant, so, when carrying out the liquid medicine dropping, the liquid medicine homodisperse gets into lung tissue to both sides main tributary trachea, realizes the accuracy and doses.

In order to facilitate the injection of the liquid medicine, in the present embodiment, a luer 21 is further disposed at one end of the administration catheter 2, as shown in fig. 5; the luer 21 is adapted to the injection port of the syringe 5. When injecting the drug solution, the injection port of the syringe is connected to the luer of the administration catheter, and the drug solution is injected into the administration catheter, as shown in fig. 6.

Because the inner diameter of the common tracheal catheter for the neonate is 2.5-4.5 mm, and the length is 21-29 cm, in the embodiment, the pipe diameter of the administration catheter 2 is not more than 2.25mm, and the length of the administration catheter 2 is 21-29 cm.

In this embodiment, the material of the administration tube 2 is PVC (Polyvinyl chloride), PP (Polypropylene), or PUR (polyurethane).

In this embodiment, the plug 4 is made of polyethylene or silica gel.

In this embodiment, the connecting pipe 1 is made of PVC.

Of course, the present invention may have other embodiments, and those skilled in the art may make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the appended claims.
