Description

Technical Field

[0001] The invention belongs to the field of nasal irrigators, and in particular relates to an adjustable nasal irrigator. Background Art

[0002] Nasal irrigation is a scientific care for the normal physiological function of the nasal cavity. It can promote the crusting of secretions in the nasal cavity and discharge them from the nasal cavity. It can also discharge dust, dirt, bacteria, etc. from the nasal mucosa to reduce nasal and sinus mucosal infection and help the nasal cilia to return to normal. Therefore, it is beneficial to maintain the normal physiological function of the nasal cavity and relieve symptoms such as nasal congestion and runny nose. It has a good nursing effect on nasal diseases such as acute and chronic rhinitis, sinusitis, allergic rhinitis, nasal polyps, etc.

[0003] The patent application with announcement number CN221866576U discloses an adjustable nasal irrigator, and paragraph 0040 of its specification discloses: when a user who uses the irrigator for the first time needs to irrigate the nasal cavity, he can pour the well-proportioned irrigating liquid into the inside of the bottle body, screw on the bottle cap, then turn the bottle body upside down, and put the nasal plug into the nasal cavity. At this time, pinch the connecting rod so that the connecting rod drives the slider to move along the direction of the slide groove. The movement of the slider can squeeze the spring, so that there is resistance to the movement of the slider and the connecting rod, and then use the connecting rod to squeeze the bottle body so that the irrigating liquid sprays into the nasal cavity along the irrigating tube and the nasal plug to prevent the user from squeezing too much, and then it is convenient to prevent the water pressure from being too strong and causing water to enter the ear canal and cause damage. When the user can control the force of squeezing the bottle body by himself, he can unscrew the threaded rod and separate the connecting rod from the slider. At this time, the connecting rod can be removed, and then the mounting ring can be separated from the bottle body, which is convenient for users who have mastered the use of the irrigator.

[0004] However, in actual use, 1. the bottle body needs to be squeezed by a connecting rod. Since the connecting rod slides between the two mounting rings, it cannot rotate in the circumferential direction of the bottle body, and the outer wall of the bottle body cannot be pressed in any direction by the connecting rod, which will increase the problem of excessive squeezing force on the bottle body;

[0005] 2. The connecting rod needs to be separated from one side of the slider by unscrewing the threaded rod, and then the connecting rod can be removed, and then the mounting ring can be separated from the bottle body. Because there are multiple threaded rods, multiple threaded rods need to be removed from the upper side of the slider to remove the bottle body, and this process will reduce the efficiency of removing the bottle body.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] A nasal irrigator is a medical device used to clean the nasal cavity, also known as a nasal wash pot, a nasal snot pot, etc. Nasal irrigator: A tool used to clean the nasal cavity. By adjusting and controlling the switch of the one-way water outlet valve and the one-way air inlet valve by the size of the pressure applied to the elastic bottle by hand and the speed of relaxation, a special nasal wash is sent into the nostrils, flows through the part of the nasal vestibule exposed outside the head, the sinuses, and the nasal passages, bypasses the nasopharynx, or is discharged from one nostril, or is discharged from the mouth. Through the above paths, with the help of the impact force of the physiological saline water flow, the pathogenic bacteria and dirt that have accumulated in the nasal cavity are discharged, so that the nasal cavity can restore its normal physiological environment, restore the self-detoxification function of the nasal cavity, and achieve the purpose of protecting the nasal cavity. The nasal cavity is a narrow and long cavity with a narrow top and a wide bottom, starting from the anterior nostril in front and ending at the posterior nostril in the back, and communicating with the nasopharynx. It is divided into left and right cavities by the nasal septum, and each nasal cavity includes the nasal vestibule and the proper nasal cavity. The nasal cavity is divided into two cavities, left and right, by a longitudinal nasal septum. The nasal septum is often located to one side, so the size and shape of the left and right nasal cavities are often asymmetrical. The nasal cavity communicates with the outside world through the nostrils to the front and the bottom, and communicates with the nasopharynx to the back, which is called the posterior nasal aperture. Each nasal cavity is divided into two parts: the nasal vestibule and the proper nasal cavity. There are nasal hairs in the nasal cavity, which filter the inhaled air and reduce the inhalation of harmful substances such as dust. There are olfactory cells and secretory glands in the nasal mucosa, as well as a fairly rich number of capillaries. Therefore, the nasal cavity can warm and humidify the inhaled gas. The nasal cavity is composed of bones and cartilages and the mucosa and skin covering their surfaces. It is located between the base of the skull and the oral cavity, and is connected to the sinuses around it. The nasal septum divides the nasal cavity into left and right sides in the middle. Each nasal cavity is divided into the nasal vestibule and the proper nasal cavity by the nasal threshold. The front is connected to the anterior nostril through the nasal vestibule, and the back is connected to the nasopharyngeal cavity through the posterior nasal aperture. Each nasal cavity has a roof, a floor, an inner wall, and an outer wall. It is dome-shaped. The front section is inclined upward and is composed of the nasal bone and the nasal process of the frontal bone; the rear section is inclined downward, which is the anterior wall of the sphenoid sinus; the middle section is horizontal, which is the horizontal plate of the ethmoid bone that separates the anterior skull base. There are many holes (ethmoid holes) on the plate, so it is also called the cribriform plate. The olfactory filaments of the olfactory mucosa enter the skull through the cribriform holes. The olfactory mucosa of the olfactory area is distributed in the middle of the roof of the nasal cavity, downward to the upper part of the nasal septum and the upper part of the lateral wall of the nasal cavity. The cribriform plate is thin and fragile, and it is easy to be damaged by trauma such as anterior skull base fracture or nasal surgery at this site; anterior skull base meningioma can sometimes destroy the cribriform plate and enter the nasal cavity; olfactory neuroblastoma can destroy the cribriform plate through the nasal cavity and enter the skull. That is the nasal septum. It is composed of two parts, the bony and cartilaginous nasal septum. The upper front part is the vertical plate of the ethmoid bone, the lower back part is the vomer bone, and the lower front part is the nasal septum cartilage. The two sides of the nasal septum are covered with mucosa, which is thicker than the corresponding part of the middle turbinate. The mucosa contains a large number of glands and blood vessels. The nasal septum is often biased to one side. It is rich in blood vessels in the front and lower part and is shallow. Trauma or dry stimulation can easily cause bleeding. 90% of nosebleeds occur in this area, so it is called the bleeding area, Little area or Kiesselbach area. Therefore, during transsphenoidal surgery, the location of the septum mucosa incision should be as far as possible in the back of the nasal septum, that is, at the junction of the cartilage and bone of the nasal septum or behind it, to avoid cutting the Little area and causing more bleeding.It is composed of maxillary bone, lacrimal bone, turbinate, ethmoid labyrinth, vertical plate of palate and pterygoid process of sphenoid bone. There are three long bone pieces arranged in a ladder shape from bottom to top on the outer wall of nasal cavity, namely, the lower, middle and superior turbinate. Their sizes are reduced by 1 / 3 respectively, and their front ends are moved back by about 1 / 3 respectively. There is a gap between the lower part of each turbinate and the outer wall of nasal cavity, which are called the lower, middle and superior nasal meatus respectively. The nasal meatus between turbinate and nasal septum is the common nasal meatus. During pituitary surgery via unilateral nasal cavity-sphenoid sinus approach, the nasal retractor should be entered along the common nasal meatus. Superior turbinate and superior nasal meatus: The superior turbinate is the smallest of the three turbinates, located on the upper and posterior part of the outer wall of nasal cavity, and sometimes only a mucosal fold. The posterior ethmoid sinus opens into the superior nasal meatus. The sphenoethmoid recess is located at the posterior and superior part of the posterior end of the superior turbinate, where the sphenoid sinus opens. Olfactory mucosa is also distributed in the superior turbinate and superior nasal meatus. Sometimes there is a smaller uppermost turbinate behind and above the superior turbinate. The uppermost turbinate and the uppermost turbinate are located in a narrow area above and behind the outer wall of the nasal cavity. The middle turbinate and the middle nasal meatus: The middle turbinate is the landmark of the inner wall of the ethmoid sinus and can be divided into two parts, the front and the back. The front of the middle turbinate is attached to the bone of the anterior skull base at the junction of the ethmoid sinus roof and the horizontal plate of the ethmoid bone. The back of the middle turbinate extends backward, and the back end is attached downward to the outer wall of the nasal cavity at the ethmoid ridge of the vertical process of the palatine bone. The sphenopalatine foramen is located about 12 mm above and behind the upper boundary of the posterior nasal aperture, through which blood vessels and nerves of the same name pass. There are two ridges on the outer wall of the middle nasal meatus. The front and lower one is an arc-shaped ridge-like ridge, called the uncinate process; the back and upper one is the ethmoid bulla, which belongs to the ethmoid sinus structure. There is a semilunar fissure between the two, called the semilunar fissure. The funnel-shaped space that gradually expands from the semilunar fissure to the front and bottom and the outside is the ethmoid infundibulum. The inner boundary of the ethmoid infundibulum is the uncinate process, the outer boundary is the orbital cardboard, the frontal process of the maxilla is the frontal process, and the lacrimal bone is the outside. It communicates with the middle nasal meatus through the semilunar fissure inward, the front boundary is the blind end, and the frontal upper part is called the frontal recess. The frontal sinus opens to the frontal upper end of the ethmoid infundibulum through the nasofrontal canal or the frontal recess, followed by the opening of the anterior ethmoid sinus and finally the opening of the maxillary sinus. Flip up the middle turbinate, and you can easily observe the uncinate process from the gross anatomical specimen in the sagittal plane. The uncinate process is almost sagittal, almost parallel to the ethmoid bulla, with a free posterior edge. The uncinate process is attached to the ethmoid ridge of the maxilla in the front and superior part, just below the attachment of the front end of the middle turbinate and the nasal hillock to the lateral wall of the nasal cavity; immediately below it, the uncinate process is fused with the posterior part of the lacrimal bone, with no bone connection in the front and inferior part, and connected to the ethmoid process of the inferior turbinate in the posterior and inferior part. The bone at this attachment is thicker, and the uncinate process often bifurcates or widens here, and then fuses with the solid inferior turbinate bone; the posterior and superior boundary of the uncinate process separates a small bony protrusion attached to the vertical plate of the palate. The ethmoid bulla is the largest and most constant air cell of the anterior ethmoid. It is located in the middle nasal meatus, just behind the uncinate process. The ethmoid bulla is based on the orbital cardboard and protrudes inward into the middle nasal meatus. The ethmoid bulla looks like a bubble, and is a hollow, thin-walled, round bony protrusion. The anterior wall of the ethmoid bulla can extend upward to the anterior skull base, forming the posterior boundary of the frontal recess; the ethmoid bulla can fuse with the middle turbinate plate posteriorly. The inferior turbinate and inferior nasal meatus: The inferior turbinate is a separate bone piece attached to the lower part of the lateral wall of the nasal cavity and is the largest of the nasal conchae.The head of the inferior turbinate is relatively large, and the back is a huge body, which finally converges to form a thin or thick tail, the size of which depends on the degree of mucosal hyperplasia and hypertrophy. The funnel-shaped nasolacrimal duct opening can be seen below the anterior and middle third of the inferior turbinate, and the Eustachian tube pharyngeal opening is 1 to 1.5 cm from the posterior end of the inferior turbinate. Medical devices, home medical devices and personal home care products. Manual air bag nasal irrigator: Combining the combined technology of water pressure and pulsation, the warm salt water flow can effectively reach all parts of the nasal cavity and sinuses. Air-water nasal irrigator: It uses the principle of nanotechnology combined with aerodynamics and fluid dynamics to vaporize physiological saline into 20μm water particles. In addition to being used for nasal and sinus irrigation, it is also more effective for postoperative care such as nasopharyngeal carcinoma.
