Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a dual-purpose atomization / humidification inhaler. Background Art

[0002] With the development of clinical treatment technology, aerosol drug administration in non-injection drug administration has received increasing attention, and oxygen aerosol inhalation has emerged. Oxygen aerosol inhalation uses high-speed oxygen gas flow to form a mist suspension of the drug solution, which is then inhaled into the respiratory tract with breathing to achieve the purpose of treatment. The basic principle is to use high-speed oxygen flow to pass through the capillary orifice and generate negative pressure at the orifice, so that the drug solution is sucked out from the adjacent orifice. The sucked drug solution is impacted by the high-speed oxygen flow at the capillary orifice into fine droplets, which are sprayed out in the form of aerosol and enter the respiratory tract with the patient's breathing to achieve the therapeutic effect.

[0003] In addition, critically ill patients often need oxygen inhalation, and dry oxygen can irritate the respiratory mucosa, so oxygen needs to be humidified. Existing oxygen inhalers have dual functions of atomization and humidification, but during atomization and humidification operations, oxygen needs to enter the humidification bottle, and during atomization operations, the gas often carries a certain pressure, so the humidification bottle is prone to bursting, posing a threat to personal and property safety.

[0004] Application No. 201310050523.2 discloses a medical buoy-type oxygen inhaler with an integrated atomization / humidification conversion valve, which is mainly composed of an oxygen inhaler valve body, a humidification bottle and a humidification tube. A flow regulating valve and an atomization / humidification working mode conversion valve are directly arranged on the oxygen inhaler valve body. The atomization / humidification working mode conversion valve is arranged on the left side, right side or both sides in the vertical direction below the flow regulating valve; the atomization / humidification working mode conversion valve is composed of a valve sleeve, a movable valve core and a conversion valve handwheel. The conversion valve handwheel is fixedly connected to the movable valve core via a fastening screw. The grooved hole and the grooved through hole on the valve sleeve are fixedly connected to the oxygen inlet hole, oxygen outlet hole and the inner cavity of the oxygen inhaler valve body on the oxygen inhaler valve body. The movable valve core is movably connected to the valve sleeve, and a sealing ring is arranged on the movable valve core. By pressing, pulling, pushing, pulling or rotating the conversion valve hand wheel, the movable valve core is mechanically displaced in the valve sleeve, and the valve core sealing ring is used to separate the physical space of the valve sleeve cavity, so as to cleverly change the oxygen outflow path of the oxygen inhaler valve body from the oxygen inlet hole of the oxygen inhaler valve body. The above-mentioned medical buoy oxygen inhaler with integrated atomization / humidification conversion valve needs to use a valve sleeve to change the oxygen outflow path, uses many parts, and the installation and sealing operations are cumbersome, which brings inconvenience to use.

DETAILED DESCRIPTION

[0056] In order to make the technical means, creative features, objectives and effects of the invention easier to understand, the invention is further described below with reference to specific diagrams. However, the invention is not limited to the following implementation cases.

[0057] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by persons familiar with this technology. They are not used to limit the conditions under which the present invention can be implemented, and therefore have no substantive technical significance. Any structural modification, change in proportion or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical contents disclosed by the present invention.

[0058] At present, oxygen inhalers are widely used. On the one hand, oxygen inhalers are used to provide oxygen therapy to emergency patients and patients with hypoxia caused by various reasons; on the other hand, they are used to treat lung diseases such as cough and asthma. After the drug is atomized, it is administered through the lungs with good targeting, fast absorption and high bioavailability.

[0059] The commonly used oxygen inhaler at present is a buoy-type oxygen inhaler, which includes a buoy-type oxygen flow meter flow valve, an oxygen guide tube and a humidification cup. A conversion valve with a humidification / atomization mode conversion function is arranged between the flow valve and the humidification cup. Application No. 2011100610028 discloses an integrated atomization oxygen inhaler, such as Figure 1 As shown, the conversion valve 100 is provided with an oxygen chamber 110 at the upper part, and a humidified oxygen chamber 108 connected with the humidification cup is provided at the lower part. The valve body of the conversion valve 100, i.e., the fixed valve core 112, is provided with a movable valve core 115. The conversion through hole and / or groove provided on the movable valve core 115 is movably connected with the conversion through hole and / or groove provided on the fixed valve core 112. The fixed valve core 112 is provided with a through hole that can connect the humidified oxygen outlet and the humidified oxygen inlet, a through hole that can connect the oxygen inlet and the oxygen outlet, and a through hole that can connect the oxygen inlet and the atomized oxygen outlet, etc., and the movable valve core 115 is provided with a humidified oxygen connection hole 105, an oxygen connection hole 106, an atomized oxygen guide hole 101, etc. corresponding to them. The conversion switch 103 provided at one side or both sides of the movable valve core 115 can realize the connection or closing with the through hole on the fixed valve core 112, thereby achieving the purpose of humidification / atomization conversion.

[0060] In the above-mentioned buoy-type oxygen inhaler, due to the specific structure of the conversion valve 100, the flow valve and the conversion valve 100 need to be set independently, and the flow valve cannot be integrated on the valve body of the conversion valve 100, and the whole device is relatively complicated; in addition, the atomized oxygen outlet 111 and the humidified oxygen outlet 102 are respectively located on both sides of the oxygen inlet 109, and the atomized oxygen outlet 111 and the humidified oxygen outlet 102 are connected to the same oxygen output quick connector after passing through the oxygen chamber 110. Since the atomized oxygen outlet 111 and the humidified oxygen outlet 102 are far apart, it is difficult to set a channel connecting the atomized oxygen outlet 111 and the humidified oxygen outlet 102 on the conversion valve 100, which increases the production cost.

[0061] Application No. 2013100505232 discloses a medical float oxygen inhaler with integrated atomization / humidification conversion valve, such as Figure 2 As shown, the inhaler is mainly composed of an oxygen inhaler valve body 214, a humidification bottle, and a humidification tube. A flow regulating valve and an atomization / humidification working mode switching valve are directly arranged on the oxygen inhaler valve body 214. The atomization / humidification working mode switching valve is arranged on the left side, right side, or both sides in the vertical direction below the flow regulating valve.

[0062] The atomization / humidification working mode conversion valve is composed of a valve sleeve 202, a movable valve core 115, and a conversion valve hand wheel 209. The conversion valve hand wheel 209 is fixedly connected to the movable valve core 115 via a fastening screw 207. The slotted hole 201 and the slotted through hole 206 on the valve sleeve 202 are fixedly connected to the oxygen inlet hole 200, the oxygen outlet hole 213 and the inner cavity 205 of the oxygen inhaler valve body 214. The movable valve core 115 is movably connected to the valve sleeve 202, and a sealing ring 203 is provided on the movable valve core 115. By pressing, pulling, pushing, pulling or rotating the conversion valve hand wheel 209, the movable valve core 115 is mechanically displaced in the valve sleeve 202, and the oxygen outflow path of the oxygen inhaler valve body 214 from the oxygen inlet hole 200 of the oxygen inhaler valve body 214 is changed by dividing the physical space of the inner cavity of the valve sleeve 202.

[0063] The above oxygen inhaler integrates the flow regulating valve and the atomization / humidification working mode switching valve on the oxygen inhaler valve body 214, making the structure more compact. However, the switching of the atomization / humidification working mode requires the help of the valve sleeve 202. During the process of air intake and air discharge, the oxygen inlet hole 200 and the oxygen outlet hole 213 on the oxygen inhaler valve body 214 need to be movably connected with the groove hole 201, the groove through hole 206 and the movable valve core 115 on the valve sleeve 202. Since the valve sleeve 202 may have deviations during the production or installation process, it is more difficult to align the holes of the valve sleeve 202 and the oxygen inhaler valve body 214, which affects the air intake and air discharge effects.

[0064] In order to solve the above technical problems, the present application provides a dual-purpose atomization / humidification inhaler, in which an atomization / humidification mode conversion chamber is arranged in the valve body 214 of the oxygen inhaler, and an atomization / humidification mode conversion valve 307 is installed in the atomization / humidification mode conversion chamber. The atomization / humidification mode conversion chamber and the atomization / humidification mode conversion valve 307 are used in coordination to realize the conversion of the atomization and humidification functions, without the need to install a fixed valve body or valve sleeve separately, thereby solving the problem that the holes cannot be 100% aligned with each other during the above-mentioned air intake or air outlet process, thus affecting normal use.

[0065] Example 1

[0066] The present application provides a dual-purpose atomization / humidification inhaler, such as Figure 3 , 4 As shown, it includes an oxygen inhaler valve body 214, a flow regulating valve 302, a regulating valve stem 301, an air inlet connector 303, a graduated tube 304, a plastic cover 305, a nebulization / humidification mode switching valve 307, an oxygen guide tube 326 and a humidification cup 311.

[0067] A flow regulating valve 302 is provided on the valve body 214 of the oxygen inhaler, and a regulating valve stem 301 is provided at the front end of the flow regulating valve 302. The regulating valve stem 301 is located in the valve body 214 of the oxygen inhaler, and the conical top end of the regulating valve stem 301 is movably connected to an air intake joint 303. The air intake amount is controlled by the extension and contraction of the conical top end in the air intake joint 303.

[0068] A plastic cover 305, a graduated tube 304 and a floating ball 306 are arranged above the flow regulating valve 302. The air inlet joint 303 is connected to the graduated tube 304. The oxygen flowing into the air inlet joint 303 enters the graduated tube 304. The graduated tube 304 is provided with a floating ball 306 for displaying the oxygen flow rate. The oxygen in the graduated tube 304 overflows from the top and enters between the graduated tube 304 and the plastic cover 305 ( Figure 4 The direction of oxygen flow is shown in Figure ).

[0069] The oxygen inhaler valve body 214 is provided with an atomization / humidification mode conversion chamber, and the atomization / humidification mode conversion chamber is provided with an air inlet, an atomized oxygen outlet, a humidified oxygen inlet, and a humidified oxygen outlet. The atomization / humidification mode conversion chamber is also provided with an atomization / humidification mode conversion valve 307 adapted to the atomization / humidification mode conversion chamber. The conversion of the atomization and humidification modes is realized by changing the position of the atomization / humidification mode conversion valve 307 in the atomization / humidification mode conversion chamber. The atomization / humidification mode conversion valve 307 is usually located at the lower end of the flow regulating valve 302, and can be located on the left side, the right side, or both sides of the flow regulating valve 302, and can be flexibly arranged according to needs.

[0070] A humidification cup 311 is provided below the oxygen inhaler valve body 214, and the humidification cup 311 is screwed to the lower end of the oxygen inhaler valve body 214. An oxygen guide tube 326 is installed in the humidification cup 311, and one end of the oxygen guide tube 326 is connected to the oxygen outlet of the oxygen inhaler valve body 214, and the other end is located in the humidification cup 311. The humidification cup 311 is filled with pure water, so that oxygen passes through the atomization / humidification mode conversion valve 307 and the oxygen guide tube 326 and enters the humidification cup 311 for humidification treatment. A humidification core 310 is provided at the bottom end of the oxygen guide tube 326, which is used to evenly disperse oxygen, increase the contact area between oxygen and water, and increase the moisture content in oxygen.

[0071] The dual-purpose atomization / humidification inhaler provided in the present application has two modes: atomization and humidification. The switching between the two modes is achieved by the atomization / humidification mode switching valve 307. Fig.12 , 1415. The atomization / humidification mode conversion valve 307 includes a movable valve core 115 and a switching knob 312 located at one end of the movable valve core 115. The movable valve core 115 is arranged in the atomization / humidification mode conversion chamber and is movably connected to the atomization / humidification mode conversion chamber. A cavity 327 is arranged in the movable valve core 115, and a groove body 328 is arranged on the outer side in a circumferential direction. The groove body 328 is fixedly connected to the air inlet of the atomization / humidification mode conversion chamber. The groove body 328 is movably connected to the atomization oxygen outlet or the oxygen outlet of the oxygen inhaler valve body 214. The groove body 328 can be arranged in various ways. The groove body 328 is arranged in the following way in this embodiment: two first ring bodies 329 are sleeved in the middle area of ​​the outer side of the movable valve core 115, and the groove body 328 is formed between the two first ring bodies 329; in order to increase the sealing performance and prevent oxygen leakage, a sealing member 315 is arranged on the outer side of the first ring body 329, and the sealing member 315 can be a sealing ring.

[0072] The atomization / humidification mode conversion valve 307 also includes a limit cap 314, which is sleeved on the end of the movable valve core 115, and the limit cap 314 is fixedly connected to the atomization / humidification mode conversion chamber. The movable valve core 115 is fixedly connected to the switching knob 312 by screws. A plurality of convex strips 317 are circumferentially arranged on the outer side of the movable valve core 115, and a plurality of through grooves 318 adapted to the convex strips 317 are arranged in the limit cap 314. The number of convex strips 317 and the through grooves 318 is the same, and can be flexibly set according to the size of the specific size. In this embodiment, the convex strips 317 and the through grooves 318 are both set to 3. A limit ring 330 is sleeved on one end of the convex strip 317 away from the limit cap 314. The convex strip 317 and the limit ring 330 can be set as one piece, or they can be set separately, and the convex strip 317 and the limit ring 330 are fixedly connected. The limiting ring 330 may be in contact with the end of the protruding strip 317 , or may be disposed on the outside of the limiting ring 330 .

[0073] Here, "circumferential direction" refers to the outer peripheral direction or outer surface of the movable valve core 115. If the movable valve core 115 is a cylinder or a cylinder-like body, "circumferential direction" means "circumferential direction". The convex strip 317 is arranged near the end of the movable valve core 115. The convex strip 317 can extend to the end of the movable valve core 115, or a blank area can be formed between the convex strip 317 and the end of the movable valve core 115, which is the limiting area. At this time, because the outer diameter of the limiting area is equal to the inner diameter of the limiting cap 314, when the convex strip 317 and the through groove 318 are in a misaligned state, the limiting cap 314 is stuck in the limiting area, preventing the movable valve core 115 from further moving.

[0074] The movable valve core 115 is provided with a humidified oxygen inlet 107 and a humidified oxygen outlet 102, which are communicated with the cavity 327. The humidified oxygen inlet 107 and the humidified oxygen outlet 102 may be located on the same side of the tank body 328, or may be located on both sides of the tank body 328, that is, the humidified oxygen inlet 107 is arranged on one side of the tank body 328, and the humidified oxygen outlet 102 is arranged on the other side of the tank body 328.

[0075] The humidified oxygen inlet and humidified oxygen outlet provided in the atomization / humidification mode conversion chamber are connected to the humidified oxygen inlet 107 and the humidified oxygen outlet 102. An oxygen discharge channel is provided in the oxygen inhaler valve body 214, and the oxygen discharge channel is fixedly connected to the atomized oxygen outlet or the humidified oxygen outlet; the humidified oxygen inlet and the humidified oxygen outlet are movably connected to the humidified oxygen inlet, the humidified oxygen outlet, and the humidification cup.

[0076] Seals 315 are provided on both sides of the tank 328, the humidified oxygen inlet 107, and the humidified oxygen outlet 102 to seal the system formed by the atomization / humidification mode conversion chamber and the atomization / humidification mode conversion valve 307 to prevent oxygen leakage. In order to facilitate the installation of the seal 315, a second ring body is provided outside the first ring body 329, and the seal 315 is installed between the first ring body 329 and the second ring body.

[0077] The arrangement of the hollow cavity 327 and the groove body 328 in the movable valve core 115 enables the atomized oxygen outlet and the humidified oxygen outlet to be located on the same side of the air inlet, thereby avoiding an excessively large distance between the atomized oxygen outlet and the humidified oxygen outlet, thereby reducing the difficulty of designing the oxygen discharge channel.

[0078] like Fig.14 The end of the oxygen discharge channel away from the movable valve core 115 is provided with an outlet connector 313, which is connected to an external oxygen pipeline. The end of the outlet connector 313 connected to the oxygen discharge channel is the air inlet end, and the end of the outlet connector 313 connected to the external oxygen pipeline is the air outlet end. The outlet connector 313 here is a quick connector, which can be a standardized quick-insert quick connector and / or a Luer connector, and can be flexibly selected according to the quick connectors provided on the market.

[0079] like Figure 5-9 Corresponding to the oxygen flow direction in the atomization mode, the oxygen flowing out from between the calibrated tube 304 and the plastic outer cover 305 enters the atomization / humidification mode conversion chamber. Since the groove body 328 and the oxygen guide tube 326 are misaligned and not connected, the oxygen can only flow in the groove body 328 and cannot enter the humidification cup 311. At this time, the groove body 328 is connected to the atomization oxygen outlet and flows out from the outlet joint 313 for atomization.

[0080] like Figure 10-13 Corresponding to the oxygen flow direction in the humidification mode, the oxygen flowing out of the plastic cover 305 enters the atomization / humidification mode conversion chamber. Since the tank body 328 is connected to the oxygen guide tube 326, after the oxygen enters the tank body 328, it enters the humidification cup 311 through the oxygen guide tube 326, and the oxygen is humidified. Thereafter, the oxygen enters the humidified oxygen inlet 107 of the movable valve core 115, flows in the cavity 327, overflows from the humidified oxygen outlet 102, enters the humidified oxygen outlet and the oxygen discharge channel, and flows out from the outlet connector 313 for oxygen inhalation.

[0081] When installing the atomization / humidification mode conversion valve 307, first, the movable valve core 115 needs to be placed in the atomization / humidification mode conversion chamber, the limiting cap 314 needs to be inserted into the outer side of the movable valve core 115, and the limiting cap 314 needs to be tightened so that the limiting cap 314 is fixedly connected to the atomization / humidification mode conversion chamber; the switching knob 312 is installed on the outer side of the limiting cap 314, and the switching knob 312 is fixedly connected to the movable valve core 115 by the screw 316, thereby completing the installation of the atomization / humidification mode conversion valve 307. By rotating the switching knob 312, the convex strip 317 of the movable valve core 115 and the through groove 318 of the limiting cap 314 are in a facing position, and the switching knob 312 is pulled outward until the end of the limiting cap 314 is at the position of the limiting ring 330, the movable valve core 115 cannot move outward further, and the inhaler is in the atomization mode at this time; when the mode needs to be switched, the switching knob 312 is pushed inward to make the convex strip 317 leave the through groove 318, and the switching knob 312 is rotated. At this time, the convex strip 317 and the through groove 318 are in a misaligned state, and the limiting groove 314 clamps the outer side of the convex strip 317, and the inhaler is in the humidification mode.

[0082] For the convenience of use, a spring 308 is arranged inside the movable valve core 115, and the spring 308 is arranged on the side of the movable valve core 115 away from the limiting cap 314. When changing from the humidification mode to the atomization mode, the switching knob 312 is rotated so that the convex strip 317 of the movable valve core 115 is located in the through groove 318 of the limiting cap 314, and the switching knob 312 is released. The movable valve core 115 moves to the outside of the atomization / humidification mode conversion chamber under the action of the spring 308, and continues to be pulled outward until the movable valve core 115 can no longer move, the movable valve core 115 stops, and the limiting ring 330 is stuck in the position of the limiting cap 314, and it is in the humidification mode at this time.

[0083] The dual-purpose atomization / humidification inhaler of the present application uses the atomization / humidification mode conversion chamber in conjunction with the atomization / humidification mode conversion valve 307, and does not require an additional valve sleeve. On the one hand, it avoids possible deviations of the valve sleeve during production and installation that may affect the air intake and exhaust effects; on the other hand, since the use of the valve sleeve is reduced, the risk of gas leakage from the valve sleeve and the valve body is reduced, and the air tightness is better.

[0084] Example 2

[0085] Different from Example 1, Fig.16 As shown, the atomization / humidification mode conversion valve 307 includes a movable valve core 115, a cavity 327 is arranged inside the movable valve core 115, a groove body 328 is arranged around the outer side in a circumferential direction, and switching knobs 312 are arranged at both ends of the movable valve core 115, and the outer diameter of the switching knob 312 is larger than the inner diameter of the atomization / humidification mode conversion cavity.

[0086] The atomization / humidification mode switching valve 307 in this embodiment does not include a limiting cap, and the moving position of the movable valve core 115 is limited by the switching knobs 312 arranged at both ends.

[0087] In the atomization mode, the switch knob 312 on one side is pushed until it cannot be moved further, and it is in the atomization mode at this time. The oxygen passes through the groove body 328 and is directly discharged through the atomization oxygen outlet and the oxygen discharge channel. The switch knob 312 on the other side is pushed in the opposite direction until it cannot be moved. At this time, it is in the humidification mode. The oxygen passes through the groove body 328 and enters the humidification cup 311. After humidification treatment, it enters the cavity 327 of the movable valve core 115, and is discharged from the humidified oxygen outlet 102, enters the humidified oxygen outlet, and the oxygen discharge channel for oxygen inhalation.

[0088] Example 3

[0089] Different from Example 1, Fig.17 , 18 As shown, the outlet end of the outlet connector 313 is stepped or pagoda-shaped, and its outer diameter gradually increases from the outside to the inside, which is used to better fix the connector of the external device. When in use, the connector of the external device (or the external oxygen pipeline) is inserted into the outside of the outlet connector 313, and because the outlet end is stepped or pagoda-shaped, it is not easy to loosen.

[0090] The stepped or pagoda-shaped air outlet connector 113 can only be used with elastic tubes or hoses, and is not applicable to hard round tubes available on the market. In order to expand the application scenarios, a plurality of sealing rings 319 are arranged in an array on the inner side of the air outlet end of the air outlet connector 313. The number of sealing rings 319 is determined according to the size of the air outlet end distance, and is usually set to 2-4. The sealing ring 319 is elastic, and the connector of the external device is inserted into the inner side of the air outlet end. The sealing ring 319 has a limiting effect on the connector of the external device; at this time, the connector of the external device can use a hard round tube, and the elastic sealing ring 319 is used to limit the hard round tube to prevent the hard round tube from falling off during use; in addition, because the sealing ring 319 is made of elastic material, it is more convenient to pull out when used in conjunction with a hard round tube.

[0091] In order to avoid the potential safety hazard caused by excessive gas pressure, a pressure relief hole 320 is provided in the middle of the gas outlet joint 313, and a pressure relief hose 321 is provided outside the pressure relief hole 320. When the pressure is low, the pressure relief hose 321 is closely attached to the outside of the gas outlet joint 313; when the pressure is too high, the pressure relief hose 321 bulges under the action of the gas pressure, and the gas is discharged, thereby achieving a pressure relief effect.

[0092] Example 4

[0093] Different from Example 3, Fig.19 , 20 As shown, the outlet end of the outlet connector 313 is cylindrical, and a plurality of sealing rings 319 are arranged in an array inside the outlet end. The outlet connector 313 in this embodiment has only one method of use, which is to insert it into the inside of the outlet end.

[0094] Example 5

[0095] Different from Example 4, Fig.21 As shown, a sealing ring 324 is provided inside the outlet end of the outlet connector 313. Compared with the sealing ring 319, the sealing ring 324 has a larger contact area with the connector of the external device and a better limiting effect on the connector of the external device.

[0096] In order to prevent the sealing ring 324 from slipping out from the outlet end of the air outlet connector 313, a retaining ring 322 is provided on one side of the sealing ring 324 of the air outlet connector 313. The retaining ring 322 is connected to the air outlet connector 313 by threads, and the retaining ring 322 is provided with an extending end 323 for clamping the outer side of the sealing ring 324.

[0097] Example 6

[0098] Different from Example 5, Fig. 22 , 23 As shown, the retaining ring 322 is provided with a clamping column 325 on the outer side of the protruding end 323. A clamping member 11 used in conjunction with the clamping column 325 is provided on the outer side of the connector of the external device. The connector of the external device is inserted into the outlet connector 313, and the connector of the external device is rotated so that the clamping member 11 is located in the clamping column 325. At this time, the connector of the external device is not easy to slip out of the outlet connector 313. After use, the connector of the external device is rotated, and the clamping member 11 moves out of the clamping column 325, so that the connector of the external device is easy to pull out.

It should be understood that ordinary technicians in the field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection determined by the claims.
