Description

Technical Field

[0001] The utility model relates to the technical field of drug preparation inhalation, in particular to a drug preparation auxiliary inhalation device. Background Art

[0002] In the modern medical field, inhalation therapy has become an important means of treating many respiratory diseases, especially chronic diseases such as asthma and chronic obstructive pulmonary disease (COPD). Inhalation powder aerosols, as a common drug dosage form, deliver micronized drugs directly to the patient's lungs through a special inhalation device. This method allows the drug to quickly and effectively enter the systemic circulation, thereby achieving a therapeutic effect.

[0003] However, the effective use of inhaled powders depends on the distribution and deposition of drug particles in the respiratory tract. An ideal inhalation flow rate is crucial to ensure that drug particles penetrate deep into the lungs. Too low a flow rate may cause drug particles to deposit in the upper respiratory tract and fail to reach the lower respiratory tract and deep lungs, thus affecting the therapeutic effect. Especially for patients with COPD, their lung function is impaired and their inspiratory flow rate is significantly reduced, which makes it difficult for them to effectively deliver drugs to the treatment site through active inhalation. In view of this, there is an urgent need to propose an auxiliary inhalation device to help patients inhale drugs. Utility Model Content

[0004] The purpose of the utility model is to provide a drug preparation auxiliary inhalation device to solve the problems raised in the above background technology.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a drug preparation auxiliary inhalation device, such as Figure 1-Figure 3 As shown, it includes an air intake pipe 1, one end of which is equipped with a mixing chamber 4 and the other end is connected to an air pump 5. The air intake pipe 1 is the air flow channel of the device, responsible for introducing external air into the mixing chamber 4. An air intake valve 11 is installed on the air intake pipe 1 to control the on-off and flow rate of the air flow. The mixing chamber 4 is responsible for mixing the medicine with the airflow. The top of the mixing chamber 4 is connected to a dosing tube 2, which is a channel for the medicine to enter the mixing chamber 4. The top of the dosing tube 2 is connected to a medicine storage chamber 22, which can accommodate a certain amount of medicine. The dosing tube 2 is provided with a dosing valve 21 for controlling the amount and timing of the medicine. The side of the mixing chamber 4 away from the air inlet pipe 1 is connected to a spray tube 3, which is a channel for transporting the medicine from the mixing chamber 4 to the patient's respiratory tract. The outer end of the spray tube 3 is provided with a medicine outlet head 7, which contacts the patient's oral cavity. The medicine outlet head 7 is a spherical structure, and the outer wall of the medicine outlet head 7 is provided with a plurality of medicine outlet holes 71, so that the medicine can be evenly and widely distributed in the patient's respiratory tract in the form of atomization, thereby improving the utilization rate of the medicine and the therapeutic effect.

[0021] In this embodiment, a medicine adding tank 221 is installed on one side of the top of the medicine storage bin 22 for adding medicine.

[0022] Specifically, a limit plate 12 is installed on the spray pipe 3 near the medicine dispensing head 7, and a blocking plate 6 is slidably installed on the spray pipe 3 between the limit plate 12 and the medicine dispensing head 7 to facilitate movement and adjustment of the blocking plate 6.

[0023] Furthermore, a through hole 61 for the spray pipe 3 to pass through is provided in the middle of the sealing plate 6, and a groove 62 is provided on the side of the sealing plate 6 close to the medicine outlet head 7. A spring 63 is installed in the groove 62. One end of the spring 63 is located outside the groove 62 and is installed with a gasket 64. The spring 63 drives the sealing plate 6 to seal on the patient's mouth to prevent leakage of medicine.

[0024] Furthermore, a drug inlet 41 is provided on the top of the mixing chamber 4 for drug feeding, and the drug inlet 41 is connected to the drug adding pipe 2. An air inlet 42 is provided on one side of the mixing chamber 4 for air intake, and the air inlet 42 is connected to the air inlet pipe 1. A drug outlet 43 is provided on the other side of the mixing chamber 4, and the drug outlet 43 is connected to the drug spraying pipe 3 to facilitate drug discharge.

[0025] Furthermore, a guide plate 44 is provided inside the mixing chamber 4, one end of the guide plate 44 is connected to the side of the air inlet 42 away from the drug inlet 41, and a support column 441 is connected between the other end of the guide plate 44 and the inner wall of the mixing chamber 4 away from the drug inlet 41, and the other end of the guide plate 44 is supported by the support column 441 close to the drug inlet 41, for guiding flow, so that the blown-in airflow drives the falling medicine to be blown toward the spray pipe 3.

[0026] Furthermore, a slag discharge port 45 is provided at the bottom of the mixing bin 4 , and a sealing plug is installed in the slag discharge port 45 , so that the residual reagent inside the mixing bin 4 can be discharged from the slag discharge port 45 after long-term use.

[0027] When the drug preparation auxiliary inhalation device of the utility model is used, the drug outlet 7 is placed in the patient's mouth, the air inlet valve 11 is opened first, and the air pump 5 introduces air into the air inlet pipe 1. At the same time, according to the treatment needs, the drug adding valve 21 is opened, and an appropriate amount of drug is released from the drug storage bin 22 into the drug adding pipe 2. The drug then flows into the mixing bin 4, where it is fully mixed with the air. The guide plate 44 arranged inside the mixing bin 4 helps to enhance the mixing effect of the airflow and the drug, ensuring that the drug particles can be evenly distributed in the airflow.

[0028] The mixed medicine is delivered to the medicine outlet head 7 together with the air flow through the medicine spraying tube 3. The medicine outlet holes 71 evenly distributed on the outer wall of the medicine outlet head 7 enable the medicine to be widely and evenly released into the patient's respiratory tract in the form of atomization. This atomization delivery method not only improves the utilization rate of the medicine, but also helps the medicine to reach the lungs more deeply, thereby enhancing the therapeutic effect.

[0029] The sealing plate 6 can fit tightly in the patient's mouth through the cooperation of the spring 63 and the groove 62, ensuring that the medicine will not leak during the inhalation process.

[0030] After long-term use, there may be medicine residue inside the mixing bin 4. For this reason, a slag discharge port 45 is provided at the bottom of the mixing bin 4, and the residual medicine can be discharged by opening the sealing plug, which is convenient for cleaning and maintenance of the device.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
