Thus, this embodiment can be combined with the rebound mechanism 11321 used in the first or second embodiment, or the resisting rod 11331,when the guiding valve 113 is extended toward between the first and second openings 1111, 11 l2froni the third opening 1113, it is able to restore the guiding valve 113 by the magnetic attraction mechanism.

[0036] <Auxiliary Chamber>

[0037] First Preferred Embodiment

[0038] Referring to FIG. 4A, the auxiliary chamber 12 is a cylindrical hollow tubing and is open at both ends with a flow guiding valve fitting opening 121 at one end and a external medication fitting opening 123 at the other end.

[0039] The first preferred embodiment of the auxiliary chamber 12 is collocated with the first preferred embodiment of the aforementioned T-shaped adapter 111. A chamber partition 122 is extended from the flow guiding valve fitting opening 121 into the interior of the tubing, separating the interior of the auxiliary chamber 12 at least partially into two chambers, and the chamber partition 122 can be only partially extended inside the auxiliary chamber 12 or all extended inside the auxiliary chamber 12, the bottom of the auxiliary chamber 12 is used to accommodate any aerosol type of agent, such as Respimat, and preferably the bottom of the auxiliary chamber 12 is of sufficient length and shape to accommodate the agent, such as an oval.

[0040] Further, the side of the auxiliary chamber 12 can also be provided with an extra opening suitable for the Metered-dose inhaler (MDI) connector.

[0041] Second Preferred Embodiment

[0042] Referring to FIG. 4B, the second preferred embodiment of the auxiliary chamber 12 is collocated with the second preferred embodiment of the aforementioned T-shaped adapter 111, and further, a notch 1221 is provided at the top of the chamber partition 122 to engage with the end bifurcation of the resisting rod 11331.

[0043] <Ventilator Adapter>

[0044] Referring to FIG. 5A and FIG. 5B, for the aforementioned first preferred embodiment example, the connection of ventilator adapter 10 of the present invention and the regular ventilator circuit 20 is mainly through the ventilator circuit 20 connecting with the first opening 1111 and the second opening 1112 of the T-shaped adapter 111. of the T-shaped flow guiding adapter 11 separately, and preferably the first opening 1111 and/or the second opening 1112 have any kind of structure that can fit the ventilator circuit 20 tightly, the present invention is not limited to it herein, only if the structure that enables the ventilator circuit 20 to fit with the first opening 1111 and the second opening 1112 with the airtight purpose is applicable to the present invention. When the T-shaped flow guiding adapter 11 of the present invention has not yet connected with the auxiliary chamber 12, the blocking piece 113 of the guiding valve 113 in the third timing 1113 maintains at the third opening 1113 junction and makes the first opening 1111 and second opening 1112 only maintain a single unobstructed channel, which is only for the air delivery under the general circumstance when the ventilator circuit 20 does not need to administer medicine.

[0045] With further reference to FIG. 5B, when the medication is to be administered, after the resisting part 1133 of the guiding valve 113 in the third opening 1113 pushed against the chamber partition 122 of the flow guiding valve opening 121 in the auxiliary chamber 12, the guiding valve 113 will be pushed against toward the space between the first opening 1111 and the second opening 1112 of the T-shaped adapter 111, and stop at the junction when the resisting part 1133 is pushed against the junction of the tapered neck 11131 and the auxiliary chamber receiving part 11132, which makes the top of the auxiliary chamber 12 is accommodated within the auxiliary chamber receiving part 11132 of the third opening 1113, and makes the rebound mechanism 11321, such as a spring, compressed at the same time. At the moment, the spacer 11322 of the guiding valve 113 and the chamber partition 122 of the auxiliary chamber 12 are engaged and form the same plane, so that the original straight channel of the ventilator circuit 20 forms a U-shaped channel toward the third opening 1113 for the airflow 30 passing through. It is worth noting that when the guiding valve 113 of the present invention is pushed against the space between the first opening. 1111 and the second opening 1112 of the T-shaped adapter 111, it may occupy 1/2, 2/3 or all of the space, and basically, it could achieve the claimed effect of the present invention as long as the original straight channel of the ventilator circuit 20 is formed into the U-shaped channel toward the third opening 1113. At the same time, the external medication fitting opening 123 at the bottom of the auxiliary chamber 12 can be combined with the tank of a external medication 40, the external medication 40 can preferably be Respimat, when the external medication 40 is triggered to spray in the direction of the third opening 1113, the airflow 30 will carry the external medication 40 continuously toward in the direction of the patient to achieve the effect of medication administration.

[0046] The present invention successfully enables the airflow 30 of the original T-shaped adapter 111 to completely reach the position of the spray agent 40 through the airflow channel design formed by the combination and connection of the guiding valve 113, the spacer 11322, and the chamber partition 122, and is completely or almost completely carried the external medication to the patient for inhalation to achieve a better effect of medication administration.

[0047] When the medication administration is completed, it only needs to disassemble the external medication 40 tank together with the auxiliary chamber 12 from the guiding valve 113, and the rebound mechanism 11321 will return the blocking piece 1131 of the guiding valve 113 to its original position and close the third opening 1113 on a communicable state outwardly, and return the ventilator circuit 20 to its original normal use state.

[0048] The basic mechanism of the aforementioned second preferred embodiment is the same, except that the bifurcation at the end of resisting part 1133 of the guiding valve 113 in the third opening 1113 is engaged with the notch 122.1 on the chamber partition 122 of the flow guiding valve fitting opening 121 of the auxiliary chamber 12., so that the guiding valve 113 can be pushed against toward the space between the first opening 1111 and the second opening 1112. of the T-shaped adapter111, and the rebound mechanism 11321 is compressed to make the guiding valve 113 extends into the channel between the first and second openings 1111 and 1112 and to form the same airflow channel design as described above.
