Description

Technical Field

[0001] The utility model relates to the field of nasal oxygen tubes, and particularly relates to a combined nasal oxygen tube with a filter. Background Technique

[0002] A nasal oxygen tube is a medical product made of soft polyvinyl chloride and silicone rubber, consisting of a flared mouthpiece, nasal plugs, a headpiece, etc. According to different form structures, nasal oxygen tubes are divided into double-nose type, head-ring type (large, medium, small), earring type (large, medium, small), single-nose type, pediatric type, and infant type, which are composed of a flared mouthpiece, nasal plugs, a head ring, a three-way joint, an adjustment buckle, a nasal catheter, a connecting catheter, and a two-way joint. The connecting catheter and nasal catheter of the infant type can be connected or selected for use. The main function of the nasal oxygen tube is to connect with an oxygen supply system for human body oxygen inhalation. When in use, open the small package, connect the flared mouthpiece end of the nasal oxygen tube to the oxygen inhalation device, hang the head ring or earring on the head or ear, and insert the nasal plugs into the nostrils to inhale oxygen.

[0003] After retrieval, a nasal oxygen tube with the publication number CN206577216U specifically discloses a nasal oxygen tube, which includes an oxygen delivery tube, a sub-oxygen tube, and nasal plugs. One end of the oxygen delivery tube is connected to a flared joint, and the other end is connected to the sub-oxygen tube through a three-way joint. One end of the nasal plug is connected to the sub-oxygen tube, and the other end is provided with an oxygen outlet. The nasal plug is provided with a suction nose for adsorbing the inner wall of the nasal cavity. The suction nose includes a telescopic column connected to the nasal plug and a suction cup connected to the end of the telescopic column. In the nasal oxygen tube of the utility model, by designing a telescopic suction nose on the nasal plug, when inserting the tube, the suction nose and the nasal plug are inserted into the nasal cavity together, and the suction nose adsorbs the inner wall of the nasal cavity to solve the problem of oxygen supply interruption caused by the detachment of the nasal plug and improve the use safety of the nasal oxygen tube. At the same time, the suction nose adsorbs the side wall of the inner wall of the nasal cavity, rather than the septum layer between the two nasal cavities, which can solve the above technical problems without causing discomfort to the patient.

[0004] In the above patent, only through the oxygen delivery tube, sub-oxygen tube, nasal plugs, and suction nose, when inserting the tube, the suction nose and the nasal plug are inserted into the nasal cavity together, and the suction nose adsorbs the inner wall of the nasal cavity to solve the problem of oxygen supply interruption caused by the detachment of the nasal plug and improve the use safety of the nasal oxygen tube. However, during the use of this nasal oxygen tube, after the nasal oxygen tube is connected to the oxygen supply device, the oxygen transmitted from the oxygen supply device contains a certain amount of water vapor, and the water vapor contains some impurities. If oxygen is supplied for a long time, the nasal oxygen tube cannot fully provide pure oxygen for the patient, and the water vapor is likely to enter the patient's body. After long-term use, a large amount of water vapor adheres to the inside of the nasal oxygen tube, which is not convenient for the patient's daily use. It needs to be disassembled, cleaned, and replaced regularly, delaying the patient's oxygen inhalation time, and also increasing the use cost of this nasal oxygen tube.

[0005] Therefore, it is very necessary to invent a combined nasal oxygen tube with a filter to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a combined nasal oxygen tube with a filter, which avoids the problem that the oxygen containing a certain amount of water vapor passed through cannot fully provide pure oxygen supply for patients through the body, oxygen filter element, adsorption strip and shunt nasal suction tube, and also reduces the frequency of patients regularly disassembling, cleaning and replacing the nasal oxygen tube. Without delaying the patient's oxygen inhalation, the use cost of the nasal oxygen tube is reduced, so as to solve the problem that after the nasal oxygen tube is connected to the oxygen supply device in the prior art, the oxygen passed from the oxygen supply device contains a certain amount of water vapor, and the water vapor contains some impurities. If oxygen is supplied and inhaled for a long time, the nasal oxygen tube cannot fully provide pure oxygen for patients, and the water vapor is easy to enter the patient's body. After long-term use, a large amount of water vapor adheres to the inside of the nasal oxygen tube, which is not convenient for patients to use daily. It needs to be regularly disassembled, cleaned and replaced, delaying the oxygen inhalation time of patients, and also increasing the use cost of the nasal oxygen tube.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: A combined nasal oxygen tube with a filter, including a body, a fixing bolt penetrates through the outside of the body, one end of the fixing bolt is movably connected with an oxygen filter element, an adsorption strip is fixedly installed inside the body, a front-end sleeve is fixedly installed above the body, a shunt nasal suction tube is arranged inside the front-end sleeve, a hanging positioning sleeve is arranged outside the shunt nasal suction tube, a positioning card slot is opened on the inner surface of the hanging positioning sleeve, a positioning block is movably connected inside the positioning card slot, and an upper fixing sleeve is fixedly installed at one end of the positioning block.

[0008] Preferably, a total intake pipe is fixedly connected to the bottom of the body, and a fixing pipe sleeve is fixedly installed at one end of the total intake pipe.

[0009] Preferably, the oxygen filter element is threadedly connected to the body through the fixing bolt, and the adsorption strips are equidistantly distributed inside the body.

[0010] Preferably, the positioning block fixedly installed at the bottom of the upper fixing sleeve and the positioning card slot opened on the inner surface of the hanging positioning sleeve form a snap connection, and the positioning block and the positioning card slot are used in cooperation.

[0011] Preferably, a connecting pipe groove is arranged at one end of the shunt nasal suction tube, a threaded pipe is movably connected inside the connecting pipe groove, a nasal suction chamber is fixedly installed at one end of the threaded pipe, and a nasal suction catheter is fixedly installed outside the nasal suction chamber.

[0012] Preferably, the nasal suction chamber is movably connected to the shunt nasal suction tube through the threaded pipe, and the center line of the connecting pipe groove coincides with the center line of the threaded pipe.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model:

[0014] 1. Through the arrangement of the device body, the main air intake pipe, the fixing bolts, the oxygen filter element, the adsorption strips, the front end sleeve and the shunt nasal cannula, when the device is connected with the oxygen supply device to deliver oxygen to the patient, the oxygen entering the device body through the main air intake pipe first passes through the multiple groups of adsorption strips inside the device body to adsorb part of the water vapor contained in the oxygen, and then under the tandem filtration of the two groups of fixing bolts and the oxygen filter element, the oxygen is filtered, purified and isolated to filter out impurities in the oxygen and improve the purity of the oxygen, and the filtered oxygen is then provided to the patient through the shunt nasal cannula for oxygen inhalation. This coordinated use not only avoids the problem that the oxygen containing a certain amount of water vapor is transmitted and cannot fully provide the patient with pure oxygen supply, but also reduces the frequency of the patient's regular disassembly, cleaning and replacement of the nasal oxygen cannula, does not delay the patient's oxygen inhalation, and reduces the use cost of the nasal oxygen cannula, meeting the combined use of the filter and the nasal oxygen cannula;

[0015] 2. Through the arrangement of the shunt nasal suction tube, hanging positioning sleeve, positioning card slot, positioning block and upper fixing sleeve, due to the different head sizes of patients, directly hanging the shunt nasal suction tube behind the ear will not only easily cause the nasal suction tube to detach from the patient's nasal cavity, but also make it inconvenient for the patient to move normally when breathing oxygen. The shunt nasal suction tube can be first placed behind the ear and passed through the lower jaw to adjust the gap size according to the patient's head size, and then the hanging positioning sleeve and the upper fixing sleeve can be used to tighten and fix the shunt nasal suction tube at the current spacing through the positioning card slot and the positioning card block. In this way, not only is the nasal suction catheter not easy to detach from the patient's nasal cavity, but it is also convenient for the patient to carry out normal activities while wearing the nasal oxygen tube, without delaying the patient's daily activities.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0025] The present utility model provides a combined nasal oxygen tube with a filter as shown in Figures 1-5 which includes a body 1. A fixed bolt 4 penetrates through the outside of the body 1. One end of the fixed bolt 4 is movably connected to an oxygen filter element 5. An adsorption strip 6 is fixedly installed inside the body 1. A front-end sleeve 7 is fixedly installed above the body 1. A shunt nasal suction tube 8 is arranged inside the front-end sleeve 7. A hanging positioning sleeve 9 is arranged outside the shunt nasal suction tube 8. A positioning card slot 10 is formed on the inner surface of the hanging positioning sleeve 9. A positioning card block 11 is movably connected inside the positioning card slot 10. One end of the positioning card block 11 is fixedly installed with an upper fixed sleeve 12. The oxygen entering the body 1 through the total intake pipe 2 first passes through multiple groups of adsorption strips 6 inside the body 1 to adsorb part of the water vapor contained in the oxygen, and then is filtered, purified and isolated under the front and back filtration of two groups of fixed bolts 4 and the oxygen filter element 5 to filter out impurities in the oxygen and improve the purity of the oxygen.

[0026] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the bottom of the body 1 is fixedly connected to a total intake pipe 2. One end of the total intake pipe 2 is fixedly installed with a fixed pipe sleeve 3. The total intake pipe 2 and the fixed pipe sleeve 3 facilitate the connection of the nasal oxygen tube and an oxygen supply device to provide oxygen for patients. The oxygen filter element 5 is threadedly connected to the body 1 through the fixed bolt 4. The adsorption strips 6 are evenly distributed inside the body 1. Under the front and back filtration of two groups of fixed bolts 4 and the oxygen filter element 5, the oxygen is filtered, purified and isolated to filter out impurities in the oxygen and improve the purity of the oxygen. The positioning card block 11 fixedly installed at the bottom of the upper fixed sleeve 12 and the positioning card slot 10 formed on the inner surface of the hanging positioning sleeve 9 form a snap connection. The positioning card block 11 and the positioning card slot 10 are used in cooperation to tighten and fix the hanging positioning sleeve 9 and the upper fixed sleeve 12 to the shunt nasal suction tube 8 with different current spacing sizes.

[0027] As shown inFigure 1 , Figure 4 and Figure 5 As shown in ,

[0028] , one end of the shunt nasal suction tube 8 is provided with a connecting pipe groove 13. A threaded pipe 14 is movably connected inside the connecting pipe groove 13. One end of the threaded pipe 14 is fixedly installed with a nasal suction chamber 15. A nasal suction catheter 16 is fixedly installed outside the nasal suction chamber 15. The two groups of nasal suction catheters 16 are on the nasal suction chamber 15, which is convenient for extending into the patient's nasal cavity to provide dual-hole oxygen supply, ensuring the normal oxygen inhalation frequency of the patient. The nasal suction chamber 15 is movably connected to the shunt nasal suction tube 8 through the threaded pipe 14. The center line of the connecting pipe groove 13 coincides with the center line of the threaded pipe 14. The overall structure of the threaded pipe 14 is simple and the operation is easy. It is convenient for the patient to disassemble the nasal suction chamber 15 for disinfection and cleaning after long-term use, ensuring cleanliness and hygiene during oxygen inhalation.

[0028] The working principle of this utility model: First, according to the size of the patient's head, the shunt nasal suction tube 8 is passed around the ear and through the lower jaw to adjust the gap. Then, through the positioning card slot 10 and the positioning block 11, the hanging positioning sleeve 9 and the upper fixing sleeve 12 tighten and fix the shunt nasal suction tube 8 at the current spacing. In this way, the nasal suction catheter 16 is not easily detached from the patient's nasal cavity, and it is also convenient for the patient to move normally when wearing the nasal oxygen tube. Then, the total intake pipe 2, the fixing pipe sleeve 3 and the oxygen supply device are connected to provide oxygen for the patient. After the preparation work is completed, the external power supply can be turned on to turn on the oxygen supply device to provide oxygen for the patient. Then, the oxygen entering the body 1 through the total intake pipe 2 passes through multiple adsorption strips 6 inside the body 1 to adsorb part of the water vapor contained in the oxygen. Then, under the filtration of the two fixing bolts 4 and the oxygen filter element 5, the oxygen is filtered, purified and isolated, and the impurities in the oxygen are filtered out to improve the purity of the oxygen. Subsequently, the filtered oxygen is supplied to the patient for oxygen inhalation through the shunt nasal suction tube 8. In this way, the problem that the transferred oxygen containing a certain amount of water vapor cannot fully provide pure oxygen supply to the patient is avoided, and the oxygen inhalation work of the patient is completed, meeting the combined use of the filter and the nasal oxygen tube. Finally, after all patients complete the wearing and oxygen inhalation work of the nasal oxygen tube according to the above operations, turn off the external power supply, unplug the total intake pipe 2 and the fixing pipe sleeve 3 connected to the oxygen supply device, and disassemble the nasal suction chamber 15 through the threaded pipe 14 for disinfection and cleaning to ensure cleanliness and hygiene during oxygen inhalation. Just like this, the use process of the combined nasal oxygen tube with a filter is completed.
