Description

Technical Field

[0001] The invention relates to a nasal washer and belongs to the technical field of medical equipment. Background Art

[0002] In the prior art, a nasal washer is a tool for cleaning the nasal cavity. It usually uses a certain pressure (or suction, or gravity, or mechanical pressure) to send physiological saline into the nostrils, which flows through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages, bypassing the nasopharynx, or is discharged from one nostril, or from the mouth. Through the above paths, with the help of the bactericidal effect of the physiological saline itself and the impact force of the water flow, the pathogens and pollutants 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. Nasal washers can be divided into simple bottle type, handheld air bag type and electric nasal washer water column type.

[0003] However, most of the existing nasal washers are operated in a manner of entering the nasal cavity and being discharged from the mouth, which easily causes the saline solution after cleaning to flow into the esophagus and trachea, causing great harm to the human body.

[0004] In order to prevent the above problems from occurring in patients, it is necessary to design a nasal washer that can overcome the above-mentioned defects. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific drawings and embodiments. Example

[0027] like Figure 1~Figure 4As shown, embodiment 1 discloses a nasal washer, including a water supply device, a water pumping device and a water blocking device; the water supply device includes a water supply device 2 and a water supply hose 1, the outlet end of the water supply device 2 is connected to the rear end of the water supply hose 1, the front end of the water supply hose 1 is used to insert into the nasal cavity from one nostril, and the water supply device 2 is used to deliver clean water into the nasal cavity through the water supply hose 1; the water pumping device includes a water pump 3 and a water pumping hose 6, the inlet end of the water pump 3 is connected to the rear end of the water pumping hose 6, and the front end of the water pumping hose 6 is used to Insert it into the nasal cavity from the other nostril, and the water pump 3 is used to extract the sewage inside the nasal cavity through the water pump hose 6; the water blocking device includes a water plug 4, a water blocking hose 5 and a water blocking ball 7, the outlet end of the water plug 4 is connected to the rear end of the water blocking hose 5, and the front end of the water blocking hose 5 is connected to the water blocking ball 7. Fluid medium is sealed in the water plug 4, the water blocking hose 5 and the water blocking ball 7. By operating the water plug 4, the fluid medium can be driven into the water blocking ball 7, so that the water blocking ball 7 expands to cut off the connection between the nasal cavity and the oral cavity.

[0028] When used specifically, the fluid medium inside the water blocking ball 7 is first evacuated with the water blocking device 4, and then the water pumping hose 6 and the water blocking hose 5 are sent into the nasal cavity through one nostril, so that the water blocking ball 7 reaches the connection part between the nasal cavity and the oral cavity; then the water blocking device 4 is operated to make the water blocking ball 7 filled with the fluid medium expand and block the passage between the nasal cavity and the oral cavity. Then the water supply hose 1 is inserted into the appropriate position in the other nostril, the water supply device 2 is started, and the water supply hose 1 is input with clean water [clean physiological saline] through one nostril, and the water pump 3 is started at the same time and the physiological saline after cleaning is extracted from the other nostril through the water pumping hose 6. The water blocking ball 7 can prevent the physiological saline from flowing from the nasal cavity into the oral cavity during the nasal irrigation process. When the nasal cavity is cleaned, the water supply device 2 and the water pump 3 are closed, and the fluid medium in the water blocking ball 7 is extracted by the water pump 3 to shrink the water blocking ball 7. Finally, the water supply hose 1, the water blocking hose 5, the water pumping hose 6 and the water blocking ball 7 are taken out to complete the nasal washing operation.

[0029] like Figure 1 , Figure 3 As shown, in this embodiment 1, a slot 6a for embedding the water blocking hose 5 is provided on the outer wall of the water suction hose 6 along the length direction, and the water blocking hose 5 can move axially in the slot 6a. In this way, the water blocking hose 5 can be firmly combined with the water suction hose 6 and can be axially moved and adjusted in the slot 6a, which is convenient for clinical operation.

[0030] In this embodiment 1, the water feeder 2 and the water pump 3 can both be conventional products in the prior art, such as the 3301 food-grade brushless DC water pump of Shenzhen Dinghao Electronics Co., Ltd. When the electric water pump is used as the water feeder 2, the outlet end of the electric water pump is connected to the water feed hose 1; when the electric water pump is used as the water pump 3, the inlet end of the electric water pump is connected to the water pumping hose 6.

[0031] like Figure 1 , Figure 2 As shown, in this embodiment 1, the water shutoff device 4 is a syringe, and the fluid medium is gas. In practical applications, the fluid medium may also be liquid.

[0032] like Figure 1 , Figure 2 , Figure 4 As shown, in this embodiment 1, the front end of the water supply hose 1 is provided with a first trumpet-shaped external expansion head 1a, and the front end of the water extraction hose 6 is provided with a second trumpet-shaped external expansion head 6b, and the edges of the first trumpet-shaped external expansion head 1a and the second trumpet-shaped external expansion head 6b are both rounded. In this arrangement, when delivering water, the physiological saline in the water supply hose 1 is sprayed out through the first trumpet-shaped external expansion head 1a, and after washing the nasal cavity, the water is extracted through the second trumpet-shaped external expansion head 6b on the water extraction hose 6. At this time, the first trumpet-shaped external expansion head 1a and the second trumpet-shaped external expansion head 6b can prevent the water supply hose 1 and the water extraction hose 6 from falling out of the nasal cavity.

[0033] like Figure 4 As shown, in this embodiment 1, the first trumpet-shaped external expansion head 1a is made of elastic material, and a plurality of through holes 1b are arranged in the first trumpet-shaped external expansion head 1a. The inner ends of the through holes 1b are connected to the inside of the water supply hose 1, and the outer ends of the through holes 1b are evenly distributed on the outer surface of the first trumpet-shaped external expansion head 1a. With such a configuration, the water supply hose 1 can spray physiological saline in a scattered manner through the through holes 1b on the first trumpet-shaped external expansion head 1a, so that the flushing range is larger; at the same time, when water in the through holes 1b is rapidly sprayed out, the first trumpet-shaped external expansion head 1a will be appropriately expanded, so that the water supply hose 1 is not easy to fall out of the nasal cavity when delivering water. Example

[0034] like Figure 5~Figure 6 As shown, embodiment 2 discloses a nasal wash device, which is mainly different from embodiment 1 in that: the water supply hose 1 and the water extraction hose 6 are provided with an air bag 8, and the air bag 8 is connected to an air filling tube 9 which is in communication with the inside thereof, and the other end of the air filling tube 9 is connected to an air filling connector 10. With such a configuration, when the water supply hose 1 and the water extraction hose 6 are inserted into the nostrils, the air bag 8 can be inflated through the air filling connector 10, so that there is no gap between the air bag 8 and the inner wall of the nasal cavity, thereby preventing physiological saline from flowing back out of the two nostrils. Preferably, a cotton pad layer 11 is provided on the air bag 8, so that after the air bag 8 is inflated, it is in contact with the inner wall of the nasal cavity through the cotton pad layer 11, which can increase the comfort of the nasal cavity.

[0035] like Figure 4 , Figure 5As shown, in this embodiment 2, the nasal washer further includes a connecting plate 12, and tube clamps are provided on both sides of the connecting plate 12. The water supply hose 1 is detachably connected to the tube clamp on one side of the connecting plate 12, and the water extraction hose 6 is detachably connected to the tube clamp on the other side of the connecting plate 12. The connecting plate 12 is used to fix the water supply hose 1 and the water extraction hose 6. In this way, the connecting plate 12 fixes the water supply hose 1 and the water extraction hose 6 together, thereby increasing the stability of the delivery and extraction of the physiological saline solution.

[0036] In addition, in this embodiment 2, the water supply hose 1, the water suction hose 6 and the water blocking hose 5 are all provided with scales. In this way, since the length of each person's nasal cavity is different, the scales on the water supply hose 1, the water blocking hose 5 and the water suction hose 6 can be used to understand the appropriate position of each person, which is convenient for the next operation.

[0037] The above description is only a preferred embodiment of the present invention, and the above specific embodiment is not intended to limit the present invention. Various deformations and modifications may occur within the scope of the technical concept of the present invention, and any modification, modification or equivalent replacement made by a person of ordinary skill in the art based on the above description shall fall within the scope of protection of the present invention.
