Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a nasal irrigation head assembly for a nasal irrigator. Background Technology
[0002] Nasal irrigators, used for nasal irrigation, require external force (such as gravity, manual pressing, or electric drive) to deliver the cleaning solution into the nostrils. The solution flows through the nasal vestibule (the part exposed outside the head), sinuses, and exits from one nostril, or through the nasal passage and out the other. The force of the cleaning solution helps expel accumulated waste from the nasal cavity, restoring its normal physiological environment. Therefore, nasal irrigators all contain a nasal plug. When using one, the nasal plug must be inserted into the user's nostril, ensuring it completely blocks the nostril.
[0003] Existing nasal irrigation devices, whether single-hole or double-hole, are designed to accommodate users of different ages, genders, and body types with vastly different nostril sizes. Current solutions involve designing the nasal plug in a cone shape to fit these differences. However, this fit is generally not effective. For people with larger nostrils, the nasal plug may penetrate too deeply into the nasal cavity, leaving some areas unwashed. There is also a risk that the nasal plug may fall out inside the nasal cavity. Furthermore, these devices are not suitable for all people. Summary of the Invention
[0004] The main purpose of this utility model is to provide a nasal irrigation head assembly for a nasal irrigator, which aims to solve the problem of adjustable spacing and angle between the two nasal plugs of the nasal irrigator, so that the nasal irrigator can better match the differences of the population, and has the advantages of being simple, reliable and low cost.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a nasal irrigation head assembly for a nasal irrigator, comprising a nasal plug head and a connector, wherein the connector consists of two symmetrically structured outer shells, a first shell and a second shell, connected by a locking mechanism; furthermore, a sliding groove is provided at the top of the connector; the inner cavity of the connector is also provided with a hollow cylindrical movable rod 1 and a movable rod 2; the upper end of the movable rod 1 passes through the sliding groove and is fitted into the nasal plug head 1; the upper end of the movable rod 2 passes through the sliding groove and is fitted into the nasal plug head 2.
[0006] Symmetrical cylindrical positioning pins 1 and 2 are provided on both sides of movable rod 1; symmetrical cylindrical positioning pins 3 and 4 are provided on both sides of movable rod 2; wherein, positioning pin 1 is embedded in positioning hole 1 of fixed base 1, positioning pin 2 is embedded in positioning hole 3 of fixed base 3; positioning pin 3 is embedded in positioning hole 2 of fixed base 2, and positioning pin 4 is embedded in positioning hole 4 of fixed base 4; the fit between positioning pin 1 and positioning hole 1, positioning pin 2 and positioning hole 3, positioning pin 3 and positioning hole 2, and positioning pin 4 and positioning hole 4 is a sliding fit.
[0007] The inner cavity of the outer shell 2 is provided with a fixing hole 1 for fitting the fixing seat 1 and a fixing hole 2 for fitting the fixing seat 2; correspondingly, the inner cavity of the outer shell 1 is also provided with fixing holes for fitting the fixing seat 3 and fixing seat 4 respectively; the fitting of the fixing seat 1, fixing seat 2, fixing seat 3, fixing seat 4 and the fixing holes are all fixed fits.
[0008] The fixing base one, fixing base two, fixing base three and fixing base four are all made of silicone rubber or rubber.
[0009] The lower end of movable rod one is connected to the liquid inlet pipe, and the lower end of movable rod two is connected to the return pipe. Beneficial effects
[0010] This utility model's nasal irrigation tip assembly does not connect the two nasal plugs directly to the inlet and outlet tubes. Instead, they are mounted on two movable rods. These rods can be adjusted by rotating their own positioning pins within positioning holes, allowing for fine-tuning of the distance between the two nasal plugs. This design is suitable for patients with varying nostril spacing.
[0011] The nasal irrigation device described in this utility model has a simple and reliable structure, low cost, and is worthy of promotion. Attached Figure Description
