Description

Modified oxygen nasal tube

The "modified oxygen nasal tube" of the present invention relates to a technical field related to nasal tubes for supplying oxygen in a patient under anesthesia while detecting carbon dioxide concentration.

In order to increase the oxygen content of the patient during inhalation, the hospital will insert a gas supply nasal tube below the nostril of the patient. The front end of the gas supply nasal tube is connected to an oxygen supply device, and the gas supply nasal tube is located below the nostril. There are two extended openings that dissipate oxygen for inhalation by the patient. In order to grasp the breathing state of the patient, a carbon dioxide detecting tube is additionally connected to the nostril of the patient to detect whether the respiratory state of the patient is still normal by detecting the concentration of carbon dioxide emitted by the patient. In the foregoing conventional structure, since the air supply nasal canal is located under the nostril and the two extended openings are used for the escape of oxygen, the amount of oxygen is not easily concentrated, and most of the oxygen is dispersed in the air without being completely completed by the patient. Inhalation, the effect is extremely unsatisfactory; and the external carbon dioxide detection tube is also slightly troublesome and inconvenient.

After consulting the Taiwan Patent Database, although there is a pre-report related to the gas supply structure of the air supply nasal tube, No. M430282, it provides a gas supply structure for the nasal cannula, including an air inlet tube, two communicating the air inlet tube and facing the patient two a gas supply pipe of the nasal cavity, the gas supply pipe is connected at both ends of the gas inlet pipe to connect the gas source, and The two air supply ducts are inserted into the nasal cavity of the patient, wherein the end of the air supply tube is inserted into the end of the nasal cavity with a plurality of small-aperture vent holes, and the vent hole has a pore size of about one tenth of a known vent hole diameter. Or smaller, and densely attached to the air supply tube into the insertion end of the nasal cavity, to minimize the pressure of the single point of the nasal endocardium to withstand the air pressure, and into a small hole out of the air, the local wind pressure is reduced The smallest, so the damage to the endometrium of the nasal cavity can be minimized to protect the patient. However, this structure still does not deviate from the conventional shortcomings, so there is still a need for improvement.

In view of this, the creators have made a special case to research and create a cost case. The project can be used to improve the shortcomings of the existing oxygen nasal tube structure, and the oxygen nasal tube function can be improved and ideal, which meets the actual needs.

In order to improve the aforementioned deficiency, the main purpose of the creation of "modified oxygen nasal tube" is to provide an oxygen nasal tube which has the advantage of concentrated supply of oxygen, whereby the patient can actually inhale sufficient oxygen to ensure Signs of life.

The second objective of the creation of the "modified oxygen nasal tube" is to provide an oxygen nasal tube which is compounded with a carbon dioxide delivery tube, whereby a single structure can be used to simultaneously detect carbon dioxide concentration before supplying oxygen. To meet actual needs.

In order to achieve the above objects, the specific method of the present invention is: the oxygen nasal tube comprises an oxygen delivery tube and a carbon dioxide delivery tube, and the oxygen delivery tube is integrally connected with the carbon dioxide delivery tube part structure, and the oxygen nose One end of the tube is placed in the throat of the patient, allowing oxygen to be The nasal cavity directly enters the respiratory organs.

Preferably, the oxygen delivery tube includes two first tubes, each of the first tubes includes a first port, and the other opposite end of each of the first ports is connected to a joint, the joint is a trigeminal a connector, the remaining end of the trifurcation is connected to a second tube, and the end of the second tube is a second port.

Preferably, each of the first ports of the oxygen delivery tube is connected to an oxygen supply device.

Preferably, the carbon dioxide delivery tube has a partial structure integrally connected with the second tube body, and includes a third port and a fourth port.

Preferably, the third port is connected to a carbon dioxide detecting device.

I would like to elaborate on the structure of the "modified oxygen nasal tube" and the effect it can produce, together with the drawings, and the preferred embodiment of the case is described in detail below.

First, please refer to the first and second figures. In the present case, the "modified oxygen nasal tube" includes an oxygen delivery tube 1 and a carbon dioxide delivery tube 2.

Preferably, the oxygen delivery tube 1 includes two first tubes 11, each of the first tubes 11 includes a first port 111, and the other opposite end of each of the first ports 111 is connected to a joint 12. The joint 12 is a three-pronged joint. The remaining end of the joint 12 is connected to a second tubular body 13 . The second tubular body 13 has a second port 131 at the end. The first ports 111 of the oxygen delivery tubes 1 are connected to an oxygen supply device 3.

Preferably, the carbon dioxide delivery tube 2 is partially integrated with the second tube body 13. The carbon dioxide delivery tube 2 includes a third port 21 and a fourth port 22. The third port 21 is connected to a carbon dioxide detecting device 4 via a connecting pipe 23.

In practice, the oxygen delivery tube 1 is integrally connected with a part of the structure of the carbon dioxide delivery tube 2, and the second port 131 and the fourth port 22 of the oxygen nasal tube are placed in the throat portion 51 of the patient 5, so that Oxygen can enter the respiratory organs directly from the nasal cavity. The advantage is that the concentration of oxygen is not easily lost, and the concentration of carbon dioxide can be detected at the same time, which fully meets the clinical requirements.

In summary, the technical content of the "modified oxygen nasal tube" in this case is in full compliance with the requirements for the acquisition of new patents. The case was indeed exploited in the industry and was not seen in the publication or publicly used before the application, and is not a technology known to the public. Furthermore, this case effectively solves the long-standing problems in the prior art and achieves the long-term needs of relevant users and consumers. It is proved that the new model cannot be easily completed. The case is rich in "industry useability", "novelty" and "progressiveness" as stipulated in the Patent Law. The patents are submitted in accordance with the law, and the bureau is required to investigate in detail and approve the patent as soon as possible to protect the wisdom of the applicant. Property rights, encourage innovation.
