A one-way drug inhalation drug delivery device is characterized in that it includes a drug inhalation pipeline, a drug delivery pipeline, a tee and a syringe, and the three joints of the tee are respectively connected to the drug outlet of the drug inhalation pipeline, The drug inlet of the drug delivery pipeline is connected with the injection port of the syringe, and a one-way valve is installed on the drug suction pipeline and the drug delivery pipeline. The one-way valve includes a cylindrical shell, the upper part of the shell is screwed with an upper shell, the lower part of the shell is screwed with a lower shell, and a valve chamber is formed between the upper shell and the lower shell; The lower shell is provided with a drug outlet channel leading to the valve cavity. The inner mouth of the drug outlet channel is equipped with a thimble base, and the center of the thimble base is provided with a thimble integrated with it. The medicine hole; the top of the thimble is fixed with an elastic membrane, and the upper surface of the membrane is attached to the end surface of the inner mouth of the medicine inlet channel.

The above-mentioned one-way drug inhalation and administration device is characterized in that: a connector is fixedly connected to the joint part corresponding to the syringe on the tee, and the injection end of the syringe is inserted into the connector.

The one-way drug inhalation and drug delivery device is characterized in that: a drug inhalation one-way valve corresponding to the drug inhalation flow direction is installed on the drug inhalation pipeline, and a drug inhalation one-way valve corresponding to the drug delivery flow direction is installed on the drug delivery pipeline. The dosing one-way valve.

The one-way drug inhalation drug delivery device is characterized in that a drug inhalation needle is installed at the drug inhalation port of the drug inhalation pipeline.

The one-way drug inhalation and administration device is characterized in that: the administration pipeline is a catheter, and the outer end of the catheter is connected with a catheter joint.

The one-way drug delivery device is characterized in that: the three-way is a Y-shaped three-way.

The diaphragm is an elastic diaphragm, and its edge can be deformed and then bent.

The working principle of the one-way valve is:

After the liquid medicine enters from the upper shell, the pressure of the liquid medicine makes the periphery of the diaphragm turn down and forms a gap with the end face of the inner mouth of the medicine inlet channel. The medicine outlet channel flows out. When the liquid medicine enters from the lower shell, the liquid medicine enters the valve cavity and then under the pressure of the liquid medicine, the diaphragm and the end face of the inner mouth of the medicine inlet channel are more tightly fitted, preventing the liquid medicine from continuing to flow down. A one-way goal has been achieved.

(3) Beneficial effects

When the utility model absorbs medicine, the one-way valve for absorbing medicine is opened, and the one-way valve for administering medicine is closed, thereby realizing the process of absorbing medicine smoothly. When administering medicine, the one-way valve for medicine administration is opened, and the one-way valve for inhaling medicine is closed, so that the medicine administration can be realized smoothly. During the entire use process, there is no need to pull out the syringe, which effectively reduces pollution, saves time, and is easy to operate.
