Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a drug delivery device for the respiratory tract. Background Art
[0002] Respiratory drug delivery refers to a method of delivering drugs directly to the lungs and other respiratory organs through the patient's mouth and nose. This method is widely used in the treatment of asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. Respiratory drug delivery devices currently on the market include aerosol inhalers, dry powder inhalers, nebulizers, etc. These devices are designed for easy self-use by patients, but in some clinical scenarios, especially in emergency or intensive care, doctors or medical staff need to give patients drugs directly.
[0003] In hospitals or emergency medical situations, doctors often face some difficulties when administering drugs to the respiratory tract. One of the main problems is that the patient may close his mouth or be unable to open his mouth normally when he is nervous, uncooperative or unconscious, which limits the doctor's field of vision and makes it difficult for the doctor to accurately and efficiently deliver the drug to the patient's respiratory tract. This situation not only increases the difficulty of the drug administration process, but may also affect the accuracy and effectiveness of drug administration.
[0004] After searching, the Chinese utility model patent with authorization announcement number CN219208658U proposes a deep respiratory tract drug delivery device, including a drug storage cartridge, one end of the drug storage cartridge is sleeved with a push rod, the end of the push rod away from the drug storage cartridge is fixedly connected to a push handle, the other end of the drug storage cartridge is connected to a drug delivery head, and the outer surface of the drug storage cartridge is provided with anti-slip grooves. The utility model has a compact and reasonable structure and is simple and convenient to operate. When it is used for drug delivery treatment for patients in the respiratory department, it can effectively improve the work efficiency of medical staff and ensure the precise control of the drug delivery amount. At the same time, the design of the tongue depressor can effectively prevent the patient's tongue from affecting the use of the drug delivery device during the drug delivery process, effectively ensuring the smoothness of the drug delivery process and the comfort of the patient experience, and greatly improving the treatment effect.
[0005] However, this patent has the following shortcomings: only by pressing down the tongue depressor to prevent tongue interference, the medical staff's drug delivery field cannot be guaranteed, and it is difficult for doctors to deliver the drug to the patient's respiratory tract accurately and efficiently.
[0006] Based on this, the utility model provides a drug delivery device for the respiratory tract, which ensures the medical staff's field of vision for drug delivery by opening the patient's mouth. Utility Model Content
