Description

Nasal Passage Irrigation Catheter Set

technical field

The present invention relates to a nasal washing device, in particular to a nasal passage irrigation catheter device that can be carried around, operated by itself and conveniently assembled and disassembled.

Background technique

In recent years, with the development of industry and climate change, air pollution has become more and more serious, which has a great impact on life. According to the Medscape website (http://emedicine.medscape.com/article/232791- overview#a0156), about 14.6% of people in the United States suffer from chronic sinusitis, and it is conservatively estimated that it will cause about 18 to 22 million visits per year and direct medical costs of 3.4 to 5 billion US dollars per year, although so much medical expenses have been spent , but the incidence is still increasing every year. Relevant literature also pointed out that air pollution, humidity and high concentration of pollen are related to the high prevalence rate of this disease, and this related factor seems to exist in China, so it is believed that there are many patients with chronic sinusitis.

Unfortunately, according to the public information on Medscape and the website of Mayo Clinic, a well-known medical center in the United States, there is currently no cure for chronic sinusitis. Its main symptoms are nasal congestion, mucus reflux, and cough. These symptoms will haunt the patient for a lifetime. For these symptoms, the two websites also pointed out that surgical treatment can only be applied to selected cases. Antibiotic treatment is only effective in the acute attack period, and it is effective in the chronic period. It is not good, so finally it is recommended that the patient adopt long-term home treatment of moistening the nasal cavity, at least twice a day. Therefore, from the patient's point of view, moisturizing the nasal cavity can be said to be the main treatment for chronic sinusitis.

Referring to Figure 1, the interior of the nasal cavity of the human body is from the broad nasal vestibule to the middle of the nasopharynx. The upper nasal passage A1 and the middle nasal passage B1 are separated by the upper turbinate A, middle turbinate B, and inferior turbinate C from the bottom of the nasal cavity. , and the lower nasal passage C1 consists of three left and right slightly curved slits. All the mucus secreted by the sinuses is discharged through several openings located in the upper nasal passage A1 and the middle nasal passage B1, so the viscous mucus secreted by chronic sinusitis is mainly accumulated in the upper nasal passage A1 and the middle nasal passage B1. It also causes obstruction of the nasal passages.

Among the treatment methods for moistening the nasal cavity, there are methods such as hot steam inhalation and neti pot irrigation. These methods of moistening the nasal cavity mainly use water to soften the sticky mucus or scab. Although the direction of solving the problem is correct, take the method of inhaling hot steam as an example. The hot steam only follows the direction of human breathing and cannot reach the mucus or scab. The scab is located in the narrow position deep in the nasal cavity, making hot steam inhalation less effective.

In addition, there have been about 40 improvement patents for the nasal spray in China and the United States in recent years. All of the patents focus on the change of the water supply mechanism, but none of them change the direction of the water sprayed from front to back.

Referring to FIG. 2 , it is Taiwan Utility Model No. M418689 Patent, which discloses a commonly used nasal irrigator at present. The nasal irrigator includes: a squeezing part 10 and a nozzle 20 . The extruding part 10 has an inner space 11, and the nozzle 20 has a spray outlet 21 and an extension pipe part 22 extending toward the inner space 11 of the extruding part 10. When the inner space 11 is filled with water and applied from outside to inside When the extrusion part 10 is contracted by pressure, the pressure will push the water in the inner space 11 into the extension pipe part 22 , and then be sprayed out from the outlet 21 .

According to the above description, it can be seen that what patients with sinusitis really need to clean is the viscous secretions in the upper nasal passage A1 and the middle nasal passage B1. Although the known nasal irrigator can be cleaned by applying force to the squeezing part 10 and the water in the internal space 11 is pushed into the extension pipe portion 22, and then sprayed out from the outlet 21 to achieve the function of washing the nasal vestibule, but it is also limited by the nozzle 20 because it is too hard and too large to In-depth, only a single water column from front to back can be sprayed in the nasal vestibule, so it can only be washed to the lower nasal passage C1 or the wider and more normal parts with less resistance. For the deeper upper nasal passage A1 and middle nasal passage B1 However, it cannot be flushed, so it cannot really relieve the discomfort of the patient. If the symptoms continue, one day the sinus outlet will be blocked and mucus will accumulate in the sinus, causing acute sinusitis or other complications, which will cost expensive medical expenses.

In addition, the water column may be too strong and easily damage the mucous membranes, and improper control of the water volume may also cause choking.

From this point of view, the vast number of patients with chronic sinusitis are in urgent need of a device that can go deep into the nasal passage for irrigation.

Contents of the invention

Therefore, the object of the present invention is to provide a simple and effective nasal passage irrigation catheter device for moisturizing the nasal cavity.

To achieve the above object, the present invention provides a nasal passage irrigation catheter device, which includes a catheter unit and an injection unit.

The conduit unit includes a conduit body and a plurality of openings formed on the conduit body. The conduit body has an open end and a closed end opposite to the open end.

Detailed ways

The features and technical contents of the relevant patent applications of the present invention will be clearly presented in the following detailed description of three preferred embodiments with reference to the accompanying drawings.

Before detailed description, it should be noted that in this embodiment, similar elements are denoted by the same numerals.

Referring to FIG. 3 , it is a first preferred embodiment of the nasal passage irrigation catheter device of the present invention. The nasal passage irrigation catheter device includes a catheter unit 3 , a connection unit 4 , and an injection unit 5 .

The conduit unit 3 includes a conduit body 31, and a plurality of openings 32 formed on the conduit body 31, the conduit body 31 has an open end 311 and a closed end 312 opposite to the open end 311, and the closed end 312 is in a slightly curved shape, so that the catheter body 31 is convenient to turn and enter the deep part of the nasal passage.

The catheter body 31 can be divided into a connecting section 313, an extending section 314, and a flushing section 315 from the open end 311 to the closed end 312. The length of the connecting section 313 is between 1 and 5 cm. The length of the protruding section 314 is 1-5 cm, the length of the flushing section 315 is 3-10 cm, and the closed end 312 is slightly curved. Wherein, the plurality of openings 32 on the catheter body 31 are opened on the flushing section 315, and the apertures of the openings 32 farther away from the closed end 312 are gradually larger than the apertures of the openings 32 closer to the closed end 312 . Here, it should be noted that in the present invention, the catheter body 31 is made of soft materials such as silicone or latex, so that it can go straight and easily advance in the curved nasal passage, and because the normal nasal passage is the smallest About 3 centimeters, so the pipe diameter of the catheter body 31 of the present invention is designed and manufactured on the principle of not exceeding 3 centimeters.

The connection unit 4 includes a connection part 41 and a combination part 42. One end of the connection part 41 is provided with a connection thin tube 411 which is sleeved with the open end 311, and the opposite end is connected with the combination part 42. together.

It is worth mentioning that since the diameter of the connecting thin tube 411 is smaller than the diameter of the catheter body 31 , it will inevitably cause resistance to the passage of liquid, so the shorter the length of the connecting thin tube 411, the smaller the resistance.

The injection unit 5 includes a syringe 51 detachably sleeved with the combination part 42 , and an extruding part 52 disposed in the syringe 51 . Here, it should be noted that the syringe 51 and the extruding member 52 are mainly used to pressurize the liquid contained therein so that it forms a water column to be sprayed out, because the syringe 51 and the extruding member 52 There can be many variations and should not be limited to the ones disclosed in this preferred embodiment.

Referring to Fig. 4 and 5, it is a partial cross-sectional view of a human nasal passage, and the nasal cavity has a nasal vestibule E, an upper turbinate F, a middle turbinate G, a lower turbinate H, an upper nasal passage F1, and a middle nasal passage G1 And the nasal passage H1. Since the nasal vestibule is about 4 cm long, and the upper nasal passage F1, the middle nasal passage G1, and the lower nasal passage H1 are each about 5 cm long, therefore, in the first preferred embodiment, the irrigation section of the catheter body 31 315 is designed with a length of 5 cm, and the plurality of openings 32 are spaced up and down every 0.5 cm to 1 cm and are opened around the peripheral surface of the catheter tube wall. The catheter body 31 has a total length of 17 centimeters and a length of 5 centimeters after deducting the flushing section 315 at the front end, and the extension section 314 located in the nasal vestibule E is 4 centimeters long. If necessary, it can also go deep into the nasopharynx to flush mucus.

In practice, the user first inserts the flushing section 315 of the catheter body 31 into the upper nasal passage F1 or the middle nasal passage G1, and fills the flushing liquid in the syringe 51, and then uses the extruding part 52 to Pushing the flushing liquid in the syringe 51, so that the flushing liquid is sprayed out through the opening 32 on the flushing section 315 of the conduit body 31, resulting in multi-angle multiple fine water columns that are nearly perpendicular to the conduit body 31, because It is nearly perpendicular to the catheter body 31, so the catheter body 31 generally does not move forward or backward at the moment of injecting the flushing liquid, and the flushing liquid can instantly fill the nasal passage to achieve a better cleaning effect.

Since the irrigation section 315 is located in the upper nasal passage F1 of the nasal cavity, the sprayed water can directly wash the mucus or scab accumulated in the upper nasal passage F1. Similarly, when the flushing section 315 is located in the middle nasal passage G1 or the lower nasal passage H1, the sprayed water can directly flush the mucus or scab accumulated in the middle nasal passage G1 and the lower nasal passage H1.

It is worth mentioning that since the catheter body 31 is made of silica gel or latex material, the diameter of the catheter is small and soft, and it is inserted into the nasal cavity by the user. During the process of the catheter body 31 extending into the nasal passage , because the user is self-conscious, so if he feels uncomfortable during use, he can stop using it immediately, so as not to cause damage to the internal tissue of the nasal cavity. Moreover, even if the catheter body 31 cannot fully extend into the upper nasal passage F1 The multi-direction multiple water columns perpendicular to the conduit sprayed by the opening 32 on the flushing section 315 can also flush most of the surrounding areas, and the water column can be as long as 30 cm, and there is a chance to pass through the slits to reach the deep , to reduce the obstruction caused by mucus or scab attachment. It is worth noting that although the water column can reach 30 cm, the average pressure is not high because there are multiple water columns sprayed out at the same time, and it will not damage the mucous membrane.

Referring to Fig. 6, it is the second preferred embodiment of the nasal passage flushing catheter device of the present invention, the second preferred embodiment is substantially the same as the first preferred embodiment, the same will not be repeated here, the difference is , the apertures of each opening 32 on the flushing section 315 are the same size, but the openings 32 farther away from the closed end 312 are more densely arranged, and the openings 32 closer to the closed end 312 are more sparsely arranged. Configuration.

Since the pressurized water column will first release the pressure to the place with less pressure, the water column will first gather at the closed end 312. When the water column is pressurized and reaches the bottom of the closed end 312, the pressure will start to release to the plurality of openings 32, and then automatically The plurality of openings 32 eject multi-angle and multiple small water columns, and since the openings 32 farther away from the closed end 312 are arranged more densely, and the openings 32 closer to the closed end 312 are arranged more sparsely, so it can be The amount of water sprayed by the entire flushing section 315 is more even, and the flushing range is larger and more efficient.

Referring to Fig. 7, it is the third preferred embodiment of the nasal passage flushing catheter device of the present invention, the third preferred embodiment is substantially the same as the first preferred embodiment, and the similarities will not be repeated here, the difference is that , the nasal passage irrigation catheter device further includes a portable set 6 .

In the third preferred embodiment, the portable set 6 includes a container 61 filled with water 611 for injection by the injection unit 5 , a salt bag 62 , a spoon 63 , and a bag 64 . The salt bag 62 contains a plurality of salt crystals 621 for dissolving in the water 611 in the container 61 . The bag 64 is used to accommodate the catheter unit 3 , the connection unit 4 , the injection unit 5 , the container 61 , the salt bag 62 , and the spoon 63 .

It is worth mentioning that the container 61 of the third preferred embodiment has a scale 612 on the surface, and the container 61 can hold 220cc of pure water at a time. The spoon 63 has a spoon portion 631 and a handle portion 632 connected to the spoon portion 631 , and the spoon portion 631 can contain 1 gram of salt crystals 621 each time. Here, it should be noted that the inner diameter of the spoon portion 631 is about 0.8 cm×0.8 cm×0.72 cm=0.4608 cubic centimeters, and 0.4608 cubic centimeters×2.165 (the specific gravity of table salt) is about 1 gram in weight.

If 110 cc of water is added with 1 gram of salt crystal 621, the physiological saline solution with a concentration closest to 0.9% of the human body can be prepared. In other words, as long as the amount of water in the container 61 is controlled and an appropriate amount of salt crystals 621 are used, the flushing solution to be injected by the injection unit 5 can be easily prepared anytime and anywhere, and there is no need to worry about long-distance travel or going out.

The present invention provides the user with the simple assembly method of the catheter unit 3, the connection unit 4, and the injection unit 5, and then supplemented by the user's container 61 in the carry-on bag 6, the spoon 63, and The flushing solution prepared by adding water 611 into the salt bag 62 is poured into the injection barrel 51 of the injection unit 5, and the user can easily push the extrusion part 52 installed in the injection barrel to flush the solution. The solution is introduced deep into the nasal cavity, and the whole process can be completed independently without the assistance of others. The user can stop the flushing action immediately if there is any discomfort, which is good in usability and convenience.

Furthermore, since the length of the flushing section 315 of the conduit body 31 is between 5 and 10 centimeters, and the flushing section 315 is provided with a plurality of openings 32, the diameter of the openings 32 farther away from the closed end 312 is gradually larger than The closer to the closed end 312 is the diameter of the opening 32, so that the flushing solution can flush the secretions in the upper nasal passage F1 and the middle nasal passage G1, and the plurality of openings 32 provided on the flushing section 315 The closer to the closed end, the smaller the aperture, so when the flushing solution is sprayed from the catheter body 31, the apertures of different sizes can distribute the pressure more evenly, so the discomfort inside the nasal cavity can be effectively eliminated during flushing. After flushing and using, it is only necessary to pull and separate the syringe 51 from the extruding part 52, and put them together with the catheter unit 3 and the connecting unit 4 into the portable set 6. There is no complicated or troublesome process during use. Difficult assembly and disassembly, it is really convenient.

To sum up, the nasal passage irrigation catheter device of the present invention overcomes the known shortcomings of not being able to flush the deep part of the nasal cavity that needs to be moistened with the catheter unit 3, and can really improve the symptoms of patients with chronic sinusitis. The catheter unit 3 is designed for easy assembly with the connection unit 4, the injection unit 5, and the portable set 6, and considers various usage situations for the user to reduce discomfort during use. It is convenient for the user to go out to carry and prepare the flushing solution, so the purpose of the present invention can be really achieved.

The above descriptions are only three preferred embodiments of the present invention, and can not limit the scope of the present invention, that is, any simple equivalent changes and modifications made according to the claims of the present invention and the contents of the description of the invention, Still belong to the scope that the patent of the present invention covers.
