Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an inhalation drug delivery device for a bronchoscope. Background Technology

[0002] Intratracheal administration is a method of drug delivery that directly introduces medication into the trachea and lungs. In certain specific clinical situations, such as respiratory arrest or severe airway obstruction, when conventional routes of administration such as oral or intravenous administration are not feasible, intratracheal administration allows the drug to rapidly reach the site of action and exert its efficacy. Compared to traditional methods of drug delivery, bronchoscopic administration can directly target the lesion, provide precise treatment, and achieve rapid onset of action, significantly improving treatment efficiency.

[0003] Currently, the main method for administering medication via bronchoscopy involves installing a three-way connector between the trachea and the ventilator tubing. During use, the inhaler bottle is connected to the three-way connector, and with the assistance of the ventilator, the inhaled medication is directly sprayed into the lungs through the bronchoscopy to achieve the desired medication delivery. However, this method has some drawbacks. Respiratory departments use various inhalers, and doctors typically administer two or three inhalers in combination. However, the three-way connector can only connect one bottle at a time, requiring the bottle to be changed when other inhalers are needed, making the process cumbersome. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bronchoscopic inhalation delivery device that allows doctors to conveniently use two or three inhalants simultaneously.

[0005] The present invention adopts the following technical solution: An inhaler delivery device for bronchoscopy, connected between a trachea and a ventilator tubing, includes a connecting tube, mounting components, inhaler bottles, and press-to-delivery components. The connecting tube includes a medication chamber formed therein, a first connector at one end connected to the trachea, and a second connector at the other end connected to the ventilator tubing. Multiple mounting components are spaced apart along the length of the connecting tube on its outer side, each including a mounting sleeve extending upwards perpendicularly to the outer side of the connecting tube, a mounting cavity formed within the mounting sleeve for mounting the inhaler bottle, and a dispensing head at the front end of the mounting sleeve communicating with the medication chamber. Multiple inhaler bottles are installed in multiple mounting cavities, with the dispensing head inserted into their front ends. Multiple press-to-delivery components are located on the upper ends of multiple mounting sleeves and can be used to press downwards relative to the inhaler bottles.

[0006] Furthermore, the mounting sleeve includes a mounting base extending upward vertically from the outside of the connecting pipe, a sleeve mounted on the outside of the mounting base, and a connecting member disposed between the mounting base and the sleeve, wherein the mounting cavity is formed between the mounting base and the sleeve.

[0007] Furthermore, the injection head includes an insertion portion extending upward from the bottom surface inside the mounting base to form an insertion section for inserting the front end of the inhalation spray bottle, and an injection channel formed within the insertion portion to connect the inhalation spray bottle and the liquid chamber.

[0008] Furthermore, the press-to-dose delivery assembly includes a fixed base disposed at the upper end of the sleeve, a pressing block disposed downwardly in the fixed base, and an elastic connecting part disposed on the fixed base and connected to the pressing block. The lower end of the pressing block extends into the mounting cavity opposite to the inhalation spray bottle. When it moves downward, it can squeeze the inhalation spray bottle, and the elastic connecting part deforms.

[0009] Furthermore, the mounting assembly also includes a plurality of rubber pads disposed inside the sleeve that can contact the surface of the inhalation spray bottle, the plurality of rubber pads being spaced apart along the length of the sleeve.

[0010] Furthermore, the connector includes an external threaded section disposed on the upper outer periphery of the mounting base, an extension extending downward from the lower end of the sleeve for embedding into the upper part of the mounting base, and an internal threaded section disposed on the inner wall of the extension for engaging with the external threaded section.

[0011] Furthermore, it also includes a drug mixing assembly disposed at the end of the connecting tube to mix the inhalant in the drug chamber. The drug mixing assembly includes a connecting tube that can be embedded in the connecting tube on one side and connected to the second connecting head on the other side, a central block disposed on the side of the connecting tube near the drug chamber and opposite to the drug chamber, and a plurality of inclined blades disposed at circumferential intervals on the outer periphery of the central block and connected to the inner wall of the connecting tube. One end of the inclined blade is inclinedly connected to the central block and the other end extends to connect to the inner wall of the connecting tube.

[0012] Furthermore, it also includes a counting component, of which multiple counting components are provided, each corresponding to one of the multiple mounting components. The counting component is detachably mounted on the connecting pipe and includes a counter body and an elastic band mounted on the counter body that can be connected to the outer periphery of the connecting pipe.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, by defining the specific structure of the inhaler delivery device, allows the connecting tube to be connected to multiple inhaler spray bottles through the cooperation of multiple mounting components disposed on the outside of the connecting tube, multiple inhaler spray bottles installed in multiple mounting cavities, and multiple press-to-dispense components disposed on the upper end of multiple mounting sleeves. Different inhaler spray bottles can be squeezed separately to add one or more inhalers into the liquid chamber, realizing the combined use of two or three inhalers, which is convenient for doctors to use and improves the practicality of the inhaler delivery device; wherein, through multiple press-to-dispense components, the number of sprays and dosage of multiple inhaler spray bottles can be controlled separately, which is convenient for medical staff to mix and administer multiple inhalers according to the patient's condition; By placing multiple rubber pads inside the sleeve that can contact the surface of the inhalation spray bottle, the friction between the inhalation spray bottle and the mounting cavity is increased, which can prevent the inhalation spray bottle from falling to the bottom of the mounting cavity under the action of gravity, thereby preventing the inhalation spray bottle from leaking. With the drug mixing component set at the end of the connecting tube, the ventilator supplies oxygen into the connecting tube through the breathing tubing during use. The oxygen enters the connecting tube, multiple inclined blades and the drug chamber in sequence through the second connector. When the oxygen passes through the multiple inclined blades, it forms a rotating flow, which can fully mix the various inhalants in the drug chamber, while avoiding excessive drug residue in the drug chamber. By setting up multiple counting components, the number of times multiple inhaler spray bottles are pressed can be recorded separately, making it easier for medical staff to perform the next operation.
