Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

Referring to one embodiment shown in fig. 1-4 and another embodiment shown in fig. 5-8, and referring to fig. 9, the ventilation joint provided by the invention comprises a pipeline joint 1, a heating element 5 and a temperature measuring element 6, wherein the pipeline joint 1 comprises a gas transmission channel 4 with a gas inlet end 2 and a gas outlet end 3, and the gas outlet end 3 is used for connecting a gas transmission pipeline 7; the heating element 5 is arranged on the pipeline joint 1 and used for heating the gas conveyed in the gas conveying channel 4, and the heating power of the heating element 5 can be adjusted; the temperature measuring member 6 is provided on the pipe joint 1 for measuring the temperature of the heated gas formed in the gas delivery passage 4 by heating by the heating member 5.

In the technical proposal, because the gas outlet end 3 is used for connecting the gas transmission pipeline 7 and the heating power of the heating element 5 can be adjusted, and the temperature measuring member 6 is provided on the pipe joint 1 for measuring the temperature of the heated gas formed in the gas delivery passage 4 by the heating member 5, so that, in practical use, the gas outlet end 3 of the ventilation joint is connected with the gas transmission pipeline 7, gas such as respiratory gas transmitted in the gas transmission channel 4 can be heated by the heating element 5, the temperature of the heated gas is monitored by the temperature measuring element 6, by adjusting the heating power of the heating element 6, the breathing gas can be brought to the desired use temperature, thereby solving the problem that the air circuit in the prior art has poor capability of heating the breathing gas and controlling the temperature thereof through the humidifier, so that the heating power of the breathing gas can be adjusted as required to achieve a timely and accurate control of the breathing gas. In addition, when the humidifier stops working, the heating element can heat the breathing gas conveyed in the gas conveying channel to a required use temperature according to the requirement.

In addition, in practical installation and use, the gas inlet end 2 and the electric connecting terminal 18 of the heating element 5 can be simultaneously connected to a machine such as a breathing machine, for example, the gas inlet end 2 and the electric connecting terminal 18 of the heating element 5 are arranged close to each other, for example, the gas inlet end 2 and the electric connecting terminal 18 of the heating element 5 are arranged at the same end of the pipeline head 1.

In this air joint, the temperature measuring member 6 may be provided at any position of the pipe joint 1 as long as it can measure the temperature of the gas heated by the heating member 5 in the pipe joint 1. For example, in one embodiment, the temperature measuring member 6 may be disposed in the middle of the pipe joint 1 in the axial extending direction of the pipe joint 1. Alternatively, in another embodiment, referring to fig. 2 and 6, the temperature measuring member 6 is disposed downstream of the heating member 5, for example, may be disposed at the gas outlet end 3, and the temperature of the heated gas may be accurately detected regardless of the length of the pipe joint 1, so that the heating power of the heating member 5 may be more precisely adjusted.

Of course, when the gas transmission pipeline 7 is short, the heating power of the heating element 5 can be adjusted according to the outlet temperature T1 of the heated gas detected by the temperature measuring element 6 at the gas outlet end 3. Alternatively, referring to fig. 9, since the gas outlet end 3 is connected with the gas transmission pipeline 7 in actual use, the gas transmission pipeline 7 can transmit the breathing gas to the breathing mask for the patient to breathe. At this time, the air pipe 7 may have a desired length, for example, a long length, according to the actual use requirement, and the processing power of the heating member 5 may be accurately adjusted according to the ambient temperature, and therefore, the heating power of the heating member 5 may be adjusted by: the heated gas measured by the temperature measuring element 6 has an outlet temperature T1, the use environment of the gas transmission pipeline 7 has an ambient temperature T2, the gas output from the gas transmission tail end 8 of the gas transmission pipeline 7 is set to have an use temperature T3, and the gas output from the gas transmission tail end 8 of the gas transmission pipeline 7 is preset to be a preset temperature T4, wherein the use temperature T3 is obtained through the outlet temperature T1 and the ambient temperature T2, and the heating power of the heating element 5 is adjusted by comparing the use temperature T3 with the preset temperature T4. In this way, breathing gas at an appropriate temperature can be provided to the patient regardless of the length of the gas line 7 and the ambient temperature of the environment of use.

The obtaining of the usage temperature T3 through the outlet air temperature T1 and the ambient temperature T2 may be achieved in various ways, for example, in one way, the usage temperature T3 may be obtained according to the length and the inner diameter of the air transmission pipeline 7, for example, the air transmission pipeline 7 may be a standard pipeline (1.8 m long and 19mm inner diameter), and the formula T3-1/3T 1+ 2/3T 2 may be adopted. Of course, when the length and the inner diameter of the gas transmission pipeline 7 change, the coefficients (e.g., 1/3, 2/3) multiplied by T1 and T2 may also change accordingly.

Therefore, the use temperature T3 is obtained through the outlet air temperature T1 and the ambient temperature T2, the heating power of the heating gas in the pipeline connector is adjusted through the heating element by comparing the use temperature T3 with the preset temperature T4, and the temperature of the gas which is not heated (common) and has no heating function and is transmitted to the gas transmission pipeline can be controlled through the ventilation connector.

In addition, when the usage temperature T3 is obtained from the outlet temperature T1 and the ambient temperature T2, the length of the air delivery pipeline 7, the air delivery speed of the breathing air in the air delivery pipeline 7, and the like can be considered, so as to determine the usage temperature T3, for example, when the ambient temperature T2 is low, the temperature of the breathing air with the outlet temperature T1 is reduced when the breathing air is delivered in the air delivery pipeline 7, and at this time, the usage temperature T3 can be obtained according to the length of the air delivery pipeline 7, the air delivery speed of the breathing air in the air delivery pipeline 7, and the like. When the service temperature T3 is less than the preset temperature T4, the heating power of the heating member 5 is increased, and when the service temperature T3 is greater than the preset temperature T4, the heating power of the heating member 5 is decreased.

In this way, since the electrical connection terminal 18 of the heating jacket 13 protrudes from the third opening 17 and the heat insulating base 11 is located in the first opening 14 and the second opening 16, the sleeving among the pipe joint 1, the heating jacket 13 and the heat insulating base 15 can be more stable and reliable through the electrical connection terminal 18 and the heat insulating base 11.

In addition, the heating element can be a heating rod, the heating rod can have various shapes, for example, the heating rod can be a cylindrical rod, or the heating rod can be a spiral rod, for example, the spiral rod extends spirally in the gas transmission channel 4, so that the occupied space of the gas transmission channel 4 can be reduced, the heating area can be increased, the heating efficiency is high, and the gas can be heated efficiently in a short distance.
