Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a nasal cleaning and protection device for children. Background Art

[0002] The nasal cavity is an important channel for the human body to communicate with the outside world. It is responsible for filtering the air. Keeping the nasal cavity clean is essential for the normal functioning of other organs in the body, especially for patients with respiratory diseases. However, the nasal irrigators currently used are inconvenient to use and require manual hand-held operation. At the same time, the sink of the irrigator is less closed, which is inconvenient to clean and easy to breed bacteria. In addition, it is particularly important to clean the nasal cavity of children because the nasal cavity of children is more fragile and easily affected by harmful substances from the outside world.

[0003] In order to care for children's nasal cavity, the Chinese invention patent with patent number CN113181039B discloses an adjustable nasal irrigation device for pediatrics, which includes: a base frame, on which a clamping mechanism is provided; and a flushing mechanism, on which a flushing mechanism is placed. The invention can clamp the flushing mechanism through the clamping mechanism, and then adjust the position of the flushing mechanism by adjusting the position of the clamping mechanism. It has the advantages of high sealing and easy replacement, the ability to adjust the position of the nozzle, and the ability to support the user's head.

[0004] Although the above scheme improves the cleaning efficiency to a certain extent when cleaning the nasal cavity of children, in actual use, considering that the mucosa and tissue in the nasal cavity of children are relatively fragile compared with adults, especially when there is a wound, the above scheme mainly squeezes out the liquid through the squeezing ball by mechanical squeezing. Since squeezing is a sudden and concentrated action, the liquid may produce a high flow rate and pressure at the moment of discharge, and the pressure of liquid discharge cannot be accurately controlled. Therefore, when cleaning the nasal cavity of children, impact force and pressure may be generated, causing additional physical damage to the inside of the nasal cavity, expanding the wound or damaging the surrounding tissues, and affecting the flushing effect; in addition, the storage types of cleaning agents are relatively single, and the agents cannot be adjusted according to different cleaning needs. In addition, the corresponding liquid preparation and flushing cannot be carried out for the cleaning of the wounded nasal cavity, which makes the wounded nasal cavity easy to be infected with bacteria, viruses and other pathogens, increasing the risk of infection. Summary of the invention

[0034] Embodiment 1: Figures 1 to 4 As shown, the present application is a pediatric nasal cleaning and protection device, comprising a base frame 100, an adjustment mechanism 110, a clamping mechanism 120, a supporting mechanism 130, a fixing mechanism 140, a pressure sensor 150 and a flushing mechanism 200;

[0035] The flushing mechanism 200 includes a placement tube 210, a liquid outlet tube 211, a storage bag 220, an air bag 230, a mixing tube 240, and a nozzle 250;

[0036] The placement tube 210 is a cylindrical structure for placing a plurality of storage bags 220, and is made of transparent plastic, so as to facilitate observation of the medicines in the storage bags 220;

[0037] The storage bag 220 is a negative pressure bag structure, and is provided in multiple numbers and evenly arranged along the circumference of the placement tube 210, fixed inside the placement tube 210, and is used to pack different cleaning agents;

[0038] The liquid outlet pipes 211 are provided in plurality and correspond to the storage bags 220 one by one, and are respectively fixed to the top of the corresponding storage bag 220 and communicated with the inside thereof, for conveying the medicine;

[0039] The airbags 230 are provided in plurality, corresponding to the storage bags 220 one by one, and are respectively fixed to the outside of the corresponding storage bags 220, and are respectively connected to the external air pump through pipelines, so as to squeeze out the liquid from the storage bags 220 after being inflated;

[0040] The mixing tube 240 is fixed on the top of the placement tube 210 and its bottom is connected to multiple liquid outlet pipes 211, and is used to mix the medicines in the multiple storage bags 220 and transport them to the nozzle 250;

[0041] The spray head 250 is fixed above the mixing tube 240 and communicated with the interior thereof, and is used for spraying a cleaning agent to clean the nasal cavity.

[0042] The storage bag 220 is a fan-shaped structure and the two ends forming an angle are made of hard materials. The arc surface of the storage bag 220 is a flexible structure and is made of silicone material, which can be in close contact with the airbag 230 and realize the extrusion of the medicine.

[0043] The spray head 250 is made of plastic material, which has good corrosion resistance and wear resistance, and has a plurality of tiny water outlet holes 251 on its side wall to form a point-shaped water spraying mode. The multi-point flushing mode can cover the nasal cavity more comprehensively, thereby improving the efficiency and effect of flushing.

[0044] The outer side of the nozzle 250 is provided with a sponge cover 252 for preliminary cleaning of the nasal cavity and preventing foreign matter from clogging the water outlet 251 .

[0045] The adjusting mechanism 110 is used to adjust the position of the flushing mechanism 200, and includes components such as a slider and a pull rod, and realizes position adjustment by sliding and stretching so as to adapt to the usage requirements of different patients; the clamping mechanism 120 includes components such as a mounting block, a clamping block and a first elastic component, which are used to fix the flushing mechanism 200 to prevent it from moving during the flushing process; the supporting mechanism 130 includes components such as a first connecting rod, a fixing plate, a fourth elastic component and a support plate, which can be adaptively adjusted according to the patient's head shape, and is used to support the patient's head to improve the comfort and stability of flushing; all of them are prior art and will not be elaborated here.

[0046] During actual operation of the embodiment of the present application, the steps are as follows: first, different cleaning agents are respectively loaded into storage bags 220, and the storage bags 220 are placed in the placement tube 210; then, according to the height of the user, the position of the nozzle 250 is adjusted by the adjustment mechanism 110 and the clamping mechanism 120, and the user's head is fixed and supported by the support mechanism 130, so that the nozzle 250 can be inserted into the user's nasal cavity; finally, the corresponding airbag 230 is inflated by an external air pump. As the airbag 230 slowly expands, the corresponding storage bag 220 gradually squeezes out the agent inside under the expansion of the corresponding airbag 230, and mixes through the mixing tube 240, and then the mixed agent is sprayed out through the nozzle 250 to rinse the patient's nasal cavity. Since the nozzle 250 adopts a point-like water spray mode, it can cover the nasal cavity more comprehensively, thereby improving the efficiency and effect of the rinse.

[0047] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0048] The present application controls the change of the liquid discharge speed and the amount of liquid discharged from the storage bag 220 by slowly expanding the airbag 230, so that the flushing process is smoother and gentler, avoiding the sudden large flow impact in the traditional flushing method, and improving the comfort of the patient; multiple storage bags 220 can be respectively loaded with different cleaning agents, such as physiological saline, antibiotic solution, etc., and the precise control of the airbag 230 by the external air pump can achieve proportional mixing and flushing of different agents to meet the treatment needs of complex diseases. The packaging of different agents and the ability to achieve precise proportions can help to exert the best therapeutic effects of various agents and improve the overall effect of nasal flushing. At the same time, multiple cleanings with different agents can clean the nasal cavity more comprehensively, remove dirt and pathogens in the nasal cavity, and enable the flushing device to flexibly adjust the flushing scheme according to different patient needs and conditions, thereby improving the applicability and flexibility of the equipment. Doctors can choose appropriate agents and flushing methods according to the specific conditions of the patient to achieve the purpose of personalized treatment. By accurately controlling the extrusion speed and pressure of the liquid medicine, it can be ensured that the liquid medicine can evenly cover the nasal mucosa and improve the flushing effect. At the same time, it reduces the waste of liquid medicine and the discomfort of patients.

[0049] Embodiment 2: Considering that there may be a certain amount of air in the storage bag 220, in order to reduce the irritation and damage to the nasal cavity caused by the gas ejected from the nozzle 250 during the cleaning process of the nasal cavity, and to improve the uniformity of the discharge of the medicament, the present application proposes the following technical solutions for the above technical problems, specifically:

[0050] See also Figures 5 to 7 A plurality of annular elastic bands 260 are fixed inside each of the airbags 230 . The elastic bands 260 are evenly arranged in the vertical direction and are used to control the shape of the airbag 230 during the expansion process.

[0051] The elastic bands 260 have the same diameter in an initial state, and the elastic force of the vertically arranged elastic bands 260 decreases from bottom to top.

[0052] Each of the airbags 230 is provided with an air inlet hole 231 at the bottom, which is connected to an external air pump through a pipeline. The airbags 230 are made of rubber material and have good elasticity and sealing properties.

[0053] By arranging an air inlet hole 231 at the bottom of the airbag 230, the airbag 230 can gradually expand from bottom to top under the elastic action of the elastic band 260 located at the bottom during the inflation process, and squeeze the storage bag 220. The gradually expanded airbag 230 can squeeze the storage bag 220 evenly and orderly from bottom to top. This squeezing method enables the device to squeeze the medicine inside the storage bag 220 from bottom to top, which helps to form a continuous flow of liquid in the storage bag 220, thereby improving the discharge efficiency of the liquid. It can also empty the gas inside the storage bag 220 first, which helps to preliminarily discharge the gas in the storage bag 220 before the medicine is used, reduce the influence of gas on the extrusion of the medicine, and improve the accuracy and stability of the extrusion, so that the gradually expanded airbag 230 can squeeze the storage bag 220 more thoroughly, reduce the "dead corners" or "air pockets" formed by residual gas, thereby ensuring that the liquid can be discharged more completely and ensuring the uniform discharge of the storage bag 220.

[0054] The present application sets up multiple annular elastic bands 260 that are evenly arranged in the vertical direction to provide uniform support and restriction for the airbag 230, and the gradual expansion design of the annular elastic bands 260 enables the airbag 230 to evenly squeeze the storage bag 220 during the expansion process, so that the medicine inside it can flow out evenly, avoiding the sudden large flow shock or uneven liquid discharge problems that may occur in traditional methods, and also avoiding excessive local pressure on the storage bag 220, preventing the bag body from being damaged or liquid splashing, thereby ensuring the smooth progress of the discharge process.

[0055] Embodiment 3: In order to further adapt to the extrusion of liquid from the storage bag 220 with different drug storage amounts and improve the flexibility of the device, the present application proposes the following technical solutions for the above technical problems, specifically:

[0056] See also Figure 2 , Figure 8 and Fig. 9 The elastic band 260 is a bag structure made of polyurethane. The multiple elastic bands 260 arranged vertically are connected to the external liquid pump through the internal pipeline of the external airbag 230 to perform preliminary shaping on the airbag 230.

[0057] The elastic band 260 is filled with liquids such as clean water, saline and glycerin. By introducing different types of liquids and different amounts of liquids, the elasticity of the airbag 230 in the initial state can be controlled.

[0058] A pressure sensor 150 is fixed at the lower end of the nozzle 250 to detect the pressure of the nozzle 250 when discharging liquid and to cooperate with an external air pump and liquid pump to regulate the initial elasticity of the airbag 230 and the pressure when discharging the medicine.

[0059] In actual use, this embodiment takes the following three states as examples:

[0060] (1) After the water is introduced: the elastic modulus of the elastic band 260 changes to 11.0 N / m, and the elastic band 260 expands outward by 2.0 cm. Restricted by the placement tube 210, the elastic band 260 pulls the airbag 230 to move 2.0 cm toward the storage bag 220. Under the restriction of the elastic band 260 and after inflation (in the unexpanded state), the airbag 230 can initially "squeeze" the storage bag 220, and then further fill the airbag 230 with gas, causing the airbag 230 to expand from bottom to top, squeezing the gas inside the storage bag 220 upward.

[0061] (2) After the saline solution is introduced: the elastic modulus of the elastic band 260 after the change = 9.5 N / m, the elastic band 260 will expand outward by 3.5 cm, and restricted by the placement tube 210, the elastic band 260 will pull the airbag 230 to move 3.5 cm toward the storage bag 220. Under the restriction of the elastic band 260 and after inflation (in the unexpanded state), the airbag 230 can initially "squeeze" the storage bag 220, and then further fill the airbag 230 with gas, and the airbag 230 will expand from bottom to top, squeezing the gas inside the storage bag 220 upward.

[0062] (3) After the introduction of glycerol: the elastic modulus of the elastic band 260 after the change = 8.0 N / m, the rigidity of the elastic band 260 increases and its elasticity decreases, the elastic band 260 will expand outward by 5.0 cm, and restricted by the placement tube 210, the elastic band 260 will pull the airbag 230 to move 5.0 cm toward the storage bag 220. Under the restriction of the elastic band 260 and after inflation (in the unexpanded state), the airbag 230 can initially "squeeze" the storage bag 220, and then further fill the airbag 230 with gas, and the airbag 230 will expand from bottom to top, squeezing the gas inside the storage bag 220 upward.

[0063] By passing different types of liquids into the annular elastic band 260, the present application can control the initial elasticity of the elastic band 260 itself to a certain extent, that is, control the initial horizontal position (or initial elasticity) of the airbag 230 in the initial state (unexpanded state), that is, control the initial squeezing amount of the airbag 230 on the storage bag 220, which is suitable for the storage and discharge of different types and different amounts of medicines, and can also perform preliminary discharge of the gas inside the storage bag 220; the elastic modulus of the elastic band 260 can be adjusted in real time by controlling the amount of liquid passed in, so that the present device can adapt to different application scenarios and needs according to the amount of medicine inside the storage bag 220, so that the extrusion of different amounts or different properties of medicines is smoother; at the same time, by precisely controlling the elasticity of the elastic band 260, the flow path of the medicine from the storage bag 220 to the nozzle 250 can be optimized, and the resistance and fluctuation can be reduced, thereby improving the smoothness and consistency of the medicine extrusion.

[0064] By setting up a pressure sensor 150, the present application can monitor the extrusion pressure of the medicine in real time, and cooperate with the air pump and the liquid pump to realize the automatic proportioning and output of the medicine, thereby improving the convenience and accuracy of operation, reducing the errors of human operation, and enabling the device to automatically adjust the proportion and extrusion speed of the medicine according to the specific needs and medical advice of the patient, thereby improving the accuracy and efficiency of treatment.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
