Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1, a endotracheal administration catheter for a newborn comprises a lower pipeline 110, an upper pipeline 120, an administration tube 130, a connecting part 210 and an air bag 230, wherein the lower pipeline 110, the upper pipeline 120 and the administration tube 130 are respectively communicated through the connecting part 210, an included angle α is formed between the upper pipeline 120 and the administration tube 130, and the included angle α is an acute angle in the embodiment, so that a medicament flows into the lower pipeline 110 from the administration tube 130 by gravity when administered;

the air bag 230 has one end communicated with the upper pipeline 120 and the other end communicated with the air inlet pipe 140, and when the air bag is used, air flow flowing to the lower pipeline 110 can be provided for the upper pipeline 120 by squeezing the air bag 230, so that positive pressure air supply is realized, and medicine suck-back during medicine administration is prevented. The design can realize the purpose of rapid intratracheal administration without stopping the positive pressure ventilation of the trachea (the upper pipeline 120 supplies air to the lower pipeline 110), save the rescue time and increase the rescue effect.

Preferably, an administration port 220 is installed at the end of the administration tube 130, and the administration port 220 is used for being inserted and communicated with the head of the injector, so that the injector can conveniently inject the medicine into the administration tube 130.

Referring to fig. 2, the upper pipeline 120, the air inlet pipe 140 and the administration pipe 130 are respectively connected in series with a check valve 300, and the flow direction of the check valve installed on the air inlet pipe 140 is toward the air bag; the check valve attached to upper tube 120 flows in the direction toward connection unit 210, and the check valve attached to administration tube 130 flows in the direction toward connection unit 210. The design enables the air bag to unidirectionally supply air to the lower pipeline, prevents the medicine in the administration pipe from being blown out when the air bag supplies air, and also prevents the medicine from being sucked into the upper pipeline when the air bag inhales air.

Referring to fig. 3, the check valve 300 includes a valve housing 310, a hollow valve cavity 311 is formed inside the valve housing 310, the valve cavity 311 is respectively communicated with an inlet pipe 321 and an outlet pipe 322, and the inlet pipe 321 and the outlet pipe 322 are fixed on the valve housing 310;

a flow guide arc plate 330 is fixed in the valve cavity 311, a plurality of through holes 331 are formed in the flow guide protection plate 330, and the through holes 331 are used for communicating the valve cavity 311 on two sides of the flow guide arc plate 330; the flow guide arc plate 330 is also fixed with the fixing part 341 of the valve plate 340, and the fixing mode can be ultrasonic welding;

valve block 340 adopts soft material to make, for example silica gel, and valve block 340 tip is provided with round sealing ring 342, and sealing ring 342 pastes tight seal with the valve pocket 311 inner wall. After the fluid enters the inlet pipe 321, the fluid can pass through the through hole 331 and then push the valve sheet 340 away to enter the outlet pipe 322, which is a conducting direction. When the outlet pipe 322 reversely enters the fluid, the fluid cannot pass through the valve plate due to the blocking effect of the sealing ring, so that the stopping effect is achieved.

Referring to fig. 4, in actual operation, in order to avoid medicine choking caused by large dosage of medicine, the applicant fixes an orifice plate 400 between the connecting part and the one-way valve of the administration tube, and the orifice plate 400 is provided with a plurality of small holes with diameters not exceeding 0.3 mm, so that the medicine can relatively slowly enter the lower pipeline for administration.

However, the applicant has studied that the administration effect is the best by the atomization method, and therefore, the applicant communicated a portion of the administration tube between the orifice plate 400 and the check valve 300 with one end of the air guide branch tube 150, and the other end of the air guide branch tube 150 with a portion of the upper tube 120 between the check valve and the connection portion thereof, and connected a check valve 300 in series to the air guide branch tube 150 in order to prevent the diversion of the drug, and the flow direction of the check valve 300 was from the upper tube 120 to the administration tube.

After the liquid medicine is filled into the administration tube, the liquid medicine can be partially gathered at the orifice plate due to the blocking effect of the orifice plate, at the moment, the air pressure in the administration tube is increased due to the fact that the upper pipeline 120 supplies air through the air guide branch tube 150, the liquid medicine is mixed through the air pressure, and the liquid medicine is pushed to penetrate through the small hole, so that the atomization effect is obtained. The mode has higher administration speed and high drug absorption speed, thereby increasing the rescue effect and winning precious rescue time.

The details of the present invention are well known to those skilled in the art.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
