Description

Technical Field

[0001] This utility model relates to the field of nasal care equipment, specifically to a nasal filter device and a single-pump or dual-pump circulating nasal care device. Background Technology

[0002] Currently, the benefits of nasal drug delivery through the nasal mucosa are widely recognized in the medical field. However, due to limitations in nasal structure and the functionality of the drug delivery system, the absorption and distribution efficiency of nasal drugs is not high. To address the difficulty of widespread drug distribution in the nasal cavity, some medical institutions have adopted methods such as guiding patients to lie supine and breathe through their mouths, allowing the drugs to remain in the nasal cavity for an extended period. This is especially true for herbal drug delivery methods used by some traditional Chinese medicine institutions. However, patients often find this unbearable, frequently experiencing choking, severe coughing, or even respiratory arrest during the process.

[0003] To address the aforementioned contradictions and concerns, the applicant has developed a method for patients to retain medication while standing, along with a corresponding nasal care device. This device uses a pump to circulate the medication within the nasal cavity, achieving optimal distribution. Patients experience no significant discomfort while standing, and with minimal training, they can perform the procedure correctly. However, the medication circulation process carries a large amount of bacteria, secretions, detached mucosal tissue, and inhaled allergens present in the nasal cavity. Therefore, a filtration device is needed to filter the medication during circulation, ensuring that the medication does not become a source of pathogens during its long-term circulation within the nasal cavity, thus providing protection for patient treatment.

[0050] The filter housing 1 has a filter cavity 3 inside, and one end face of the filter housing 1 has an inlet hole 4 communicating with the filter cavity 3, and the other end face has an outlet hole 5 communicating with the filter cavity 3.

[0051] Preferably, the liquid inlet 4 and liquid outlet 5 can be located on opposite sides of the filter housing 1 to increase the residence time of the liquid in the filter chamber 3 and improve the filtration effect.

[0052] The flow equalization plate 2 and the filter material are disposed in the area between the liquid inlet 4 and the liquid outlet 5 of the filter housing 1. The flow equalization plate 2 is located in the area close to the liquid inlet 4 to distribute the incoming liquid evenly. The filter material is disposed in the area between the flow equalization plate 2 and the liquid outlet 5 to filter the liquid. In this way, a large number of bacteria, secretions, detached mucosal tissues, inhaled allergens, etc. present in the nasal cavity are filtered out during the drug circulation process.
