Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multi-purpose nebulizer for tracheotomy patients. Background Art

[0002] In the intensive care unit, critically ill patients often need to undergo endotracheal intubation or tracheotomy to relieve dyspnea caused by various reasons. Tracheotomy is a common operation. During the treatment process, in order to dilute sputum, relieve airway spasm or treat pulmonary infections and other treatment purposes, aerosol inhalation treatment is often required.

[0003] The existing method of aerosol inhalation for patients by nebulizers is to perform aerosol inhalation through a ventilator nebulizer with a nebulization function module or an oxygen nebulizer mask. The ventilator nebulizer is connected to the ventilator pipeline by a rigid plastic pipe, and its length is short and the angle cannot be adjusted. When the patient changes position, the nebulizer body cannot maintain a vertical state, and the liquid medicine is easy to spill out, wasting the liquid medicine or causing discomfort to the patient. The oxygen nebulizer mask nebulizes at the air inlet of the tracheotomy cannula. It is difficult for the periphery of the mask to fit tightly with the skin at the tracheotomy site. The nebulized liquid medicine escapes from the mask, resulting in a poor nebulization effect. At the same time, it is easy to form water droplets around the tracheotomy cannula, causing the skin to be wet and leading to wound infection. In addition, in the actual use process of the existing ventilator nebulizer and oxygen nebulizer mask, in order to conveniently align the nebulization outlet with the suction port of the tracheotomy cannula, medical staff often need to tilt the angle of the nebulization cup. During the tilting process, it is difficult for the liquid medicine to be attracted by the negative pressure formed by the high-speed flowing air flow to the nozzle to form a medicine mist, resulting in the problem of insufficient nebulized liquid medicine finally entering the patient's body.

[0004] At the same time, in the actual application process, due to the need for tracheotomy patients to use different auxiliary instruments at different treatment stages. For example, when performing invasive ventilator assistance, the tracheotomy cannula generally needs to be connected to the ventilator pipeline through a universal joint; when performing standby breathing exercise, the tracheotomy cannula is generally connected to a high-flow oxygen therapy instrument through a nasal cannula (a nasal cannula adapted to the tracheotomy cannula); when the patient's condition is stable or during the transition before tracheotomy tube occlusion, the tracheotomy can be connected to the ventilator pipeline or the central oxygen supply through a nasal cannula (a nasal cannula adapted to the tracheotomy cannula). However, these instruments use different pipeline connections, and there are certain differences in the specifications of these pipelines. The existing nebulizer cannot simultaneously meet the nebulization needs of patients in the above scenarios.

[0005] Therefore, there is an urgent need for a multi-purpose nebulizer for tracheotomy patients to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a multi-purpose nebulizer for tracheotomy patients, which can meet the needs of tracheotomy patients for aerosol inhalation treatment using different instruments and connecting pipelines of different specifications during the treatment process, and the liquid medicine is not easy to spill out, and the atomization effect of the liquid medicine is good.

The top of the cup cover is hermetically connected to the third port. The bottom end of the cup cover covers the cup body and is hermetically connected to the cup body. A nozzle extending upward from the bottom of the inner cavity of the cup body is arranged at the bottom of the inner cavity of the cup body. Along the direction from the bottom end of the inner cavity of the cup body to the top end of the inner cavity of the cup body, the cross-sectional dimension of the inner cavity of the nozzle gradually decreases. The top end of the mist outlet pipe is fixed in the cup cover and is communicated with the third port. The mist outlet pipe, the nozzle and the nozzle cap are all coaxially arranged. The nozzle cap is sleeved on the nozzle. The bottom end of the nozzle cap extends to the lower part of the nozzle and is spaced from the bottom end of the nozzle. The top end of the nozzle cap extends to the bottom end of the inner cavity of the mist outlet pipe, and the outer wall of the nozzle cap abuts against the inner wall of the mist outlet pipe. A flow passage communicating the bottom end of the inner cavity of the cup body with the bottom end of the inner cavity of the mist outlet pipe is arranged between the nozzle cap and the nozzle.

[0012] As an improvement of the above technical solution, the nozzle cap is made of an elastic material.

The top end of the first pipe section is fixedly connected to the cup lid, the top end of the second pipe section is fixedly connected to the bottom end of the first pipe section, and the bottom end of the second pipe section abuts against the top end of the nozzle cap. Along the direction from the bottom end of the inner cavity of the cup to the top end of the inner cavity of the cup, the cross-sectional dimension of the inner cavity of the second pipe section gradually increases, and the pipe diameter of the end of the second pipe section close to the first pipe section is the same as that of the first pipe section.

[0014] As an improvement of the above technical solution, the outer side of the nozzle is convexly provided with support ribs extending along the height direction of the nozzle, and a plurality of support ribs are arranged at intervals along the circumferential direction of the nozzle, and the support ribs support the nozzle cap.

Moreover, the third port of the T-shaped connecting pipe is connected to the first connecting pipe through a second connecting pipe, and the nebulizing cup is connected to the third port. Due to the telescopic and bending characteristics of the corrugated pipe, when the multi-purpose nebulizer for tracheostomized patients is in use, medical staff can adjust the angle of the nebulizing cup according to needs to keep the nebulizing cup as vertical as possible, avoiding the spilling of the liquid medicine in the nebulizing cup and the problem that the liquid medicine in the nebulizing cup is difficult to be attracted to the nozzle by the negative pressure formed by the high-speed flowing air flow to form a medicine mist due to the inclination of the nebulizing cup.

[0030] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0031] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above the top of", and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0033] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0034] As Figure 1-2As shown in the figure, a multi-functional nebulizer for tracheotomy patients according to an embodiment of the present utility model includes a T-shaped connecting pipe 1, a nebulizing cup 2, and an oxygen connecting pipe 3. The T-shaped connecting pipe 1 includes a first port 11, a second port 12, a first connecting pipe 13, a third port 14, and a second connecting pipe 15. The first port 11, the first connecting pipe 13, and the second port 12 are coaxially arranged, and the first port 11 is communicated with the second port 12 through the first connecting pipe 13. The first port 11 includes a first outer ring interface 111 and a first inner ring interface 112 arranged coaxially. The outer wall of the first inner ring interface 112 is spaced from the inner wall of the first outer ring interface 111. The second port 12 includes a second outer ring interface 121 and a second inner ring interface 122 arranged coaxially. The outer wall of the second inner ring interface 122 is spaced from the inner wall of the second outer ring interface 121. The third port 14 is communicated to the first connecting pipe 13 through the second connecting pipe 15, and the second connecting pipe 15 is a corrugated pipe. The top end of the nebulizing cup 2 is hermetically connected to the third port 14. The first end of the oxygen connecting pipe 3 is connected to the bottom of the nebulizing cup 2, and the second end is used to connect to an oxygen source, which can be a central oxygen supply or a nebulizing port of a ventilator.

[0035] For the multi-functional nebulizer for tracheotomy patients provided in this embodiment, the first port 11 and the second port 12 of the T-shaped connecting pipe 1 are connected through the first connecting pipe 13. The first port 11 of the T-shaped connecting pipe 1 includes a first outer ring interface 111 and a first inner ring interface 112 arranged coaxially, and the second port 12 of the T-shaped connecting pipe 1 includes a second outer ring interface 121 and a second inner ring interface 122 arranged coaxially. This enables both the first port 11 and the second port 12 of the T-shaped connecting pipe 1 to be connected to two different pipelines. As a result, the T-shaped connecting pipe 1 can either connect the incision cannula of the patient at the first port 11 and connect the oxygen therapy device at the second port 12, avoiding the problem that the atomized liquid medicine escapes from the mask when using an oxygen atomizing mask directly covering the tracheal orifice of the patient, or can be directly connected to the ventilator pipeline through the first port 11 and the second port 12, making the multi-functional nebulizer for tracheotomy patients adaptable to different usage scenarios and having a wide range of uses. Moreover, the third port 14 of the T-shaped connecting pipe 1 is connected to the first connecting pipe 13 through the second connecting pipe 15, and the nebulizing cup 2 is connected to the third port 14. Due to the telescopic and bending characteristics of the corrugated pipe, when using the multi-functional nebulizer for tracheotomy patients, medical staff can adjust the angle of the nebulizing cup 2 according to needs, making the nebulizing cup 2 as vertical as possible, avoiding the problem that the liquid medicine in the nebulizing cup 2 is difficult to be sucked to the nozzle 23 by the negative pressure formed by the high-speed flowing air flow to form a medicine mist when the nebulizing cup 2 is tilted.

[0036] Meanwhile, the multi-functional nebulizer for tracheotomy patients provided in this embodiment can also meet the nebulizing requirements of other artificial tracheal intubation patients (such as nasal intubation patients).

[0037] Optionally, as Figure 1-3As shown in the figure, the atomizing cup 2 includes a cup lid 21, a cup body 22, a nozzle 23, a mist outlet pipe 24, and a nozzle cap 25. The top end of the cup lid 21 is sealingly connected to the third port 14. The bottom end of the cup lid 21 covers the cup body 22 and is sealingly connected to the cup body 22. A nozzle 23 extending upward from the bottom of the inner cavity of the cup body 22 is provided at the bottom of the inner cavity of the cup body 22. In the direction from the bottom end to the top end of the inner cavity of the cup body 22, the cross-sectional dimension of the inner cavity of the nozzle 23 gradually decreases. The top end of the mist outlet pipe 24 is fixedly provided in the cup lid 21 and is communicated with the third port 14. The mist outlet pipe 24, the nozzle 23, and the nozzle cap 25 are all coaxially arranged. The nozzle cap 25 is sleeved on the nozzle 23. The bottom end of the nozzle cap 25 extends to the lower part of the nozzle 23 and is spaced from the bottom end of the nozzle 23. The top end of the nozzle cap 25 extends to the bottom end of the inner cavity of the mist outlet pipe 24, and the outer wall of the nozzle cap 25 abuts against the inner wall of the mist outlet pipe 24. A flow passage 10 communicating the bottom end of the inner cavity of the cup body 22 with the bottom end of the inner cavity of the mist outlet pipe 24 is provided between the nozzle cap 25 and the nozzle 23.

[0038] Further, the nozzle cap 25 is made of an elastic material, so that there is a good sealing effect at the abutting portion between the nozzle cap 25 and the mist outlet pipe 24, thereby ensuring the siphon effect at the outlet of the nozzle 23.

[0039] Further, as Figure 2 and Figure 3 shown in the figure, support ribs 231 extending in the height direction of the nozzle 23 are convexly provided on the outer side of the nozzle 23. A plurality of support ribs 231 are arranged at intervals along the circumferential direction of the nozzle 23. The support ribs 231 support the nozzle cap 25. Due to the supporting effect of the support ribs 231 on the nozzle cap 25, a gap can be formed between the inner wall of the nozzle cap 25 and the outer wall of the nozzle 23, so that a flow passage 10 is formed by enclosing the inner wall of the nozzle cap 25, the outer wall of the nozzle 23, and two adjacent support ribs 231. A plurality of support ribs 231 are arranged at intervals along the circumferential direction of the nozzle 23, which can stably support the nozzle cap 25 and form a plurality of flow passages 10 between the nozzle cap 25 and the nozzle 23.

[0040] Optionally, as Figure 1-3 shown in the figure, the mist outlet pipe 24 includes a first pipe section 241 and a second pipe section 242. The top end of the first pipe section 241 is fixedly connected to the cup lid 21. The top end of the second pipe section 242 is fixedly connected to the bottom end of the first pipe section 241. The bottom end of the second pipe section 242 abuts against the top end of the nozzle cap 25. In the direction from the bottom end to the top end of the inner cavity of the cup body 22, the cross-sectional dimension of the inner cavity of the second pipe section 242 gradually increases. The pipe diameter of the end of the second pipe section 242 close to the first pipe section 241 is the same as that of the first pipe section 241. Here, the same pipe diameter means that both the inner diameter and the outer diameter are the same. By making the cross-sectional dimension of the inner cavity of the second pipe section 242 gradually increase, the liquid medicine and oxygen can be further mixed to form a uniform medicine mist.

[0041] Optionally, the cup body 22 and the cup lid 21 are detachably connected. When it is necessary to add liquid medicine into the cup body 22, the cup lid 21 can be removed from the cup body 22, and the liquid medicine can be directly poured into the cup body 22.

[0042] Furthermore, as Figure 1 and Figure 2 shown, a medicine adding port 212 is provided on the cup lid 21, and a one-way communication structure 213 is provided in the medicine adding port 212. During the use of the multi-purpose nebulizer for tracheotomy patients, when it is inconvenient to remove the cup lid 21 from the cup body 22, the liquid medicine can be directly added into the cup body 22 through the one-way communication structure 213 from the medicine adding port 212. While the one-way communication structure 213 realizes adding the liquid medicine into the cup body 22 through the medicine adding port 212, it prevents the liquid medicine from flowing out through the medicine adding port 212 when the nebulizer cup 2 tilts. The one-way communication structure 213 can be a one-way valve or a duckbill valve. It is a common technology in the field to use a one-way valve or a duckbill valve that can be opened unidirectionally to achieve one-way communication, and its specific structure will not be elaborated here. Preferably, in this embodiment, the one-way communication structure 213 is a duckbill valve. The duckbill valve in this embodiment is a small duckbill valve, which is processed from an elastic material and relies on the elasticity of the elastic material itself to close the opening, and its opening pressure is very small. When the multi-purpose nebulizer for tracheotomy patients is in use, as the liquid medicine in the nebulizer cup 2 is atomized and ejected, the pressure in the nebulizer cup 2 will decrease to a certain extent. At this time, the duckbill valve opens, and the outside air enters the nebulizer cup 2 through the medicine adding port 212 and the duckbill valve, preventing the pressure in the nebulizer cup 2 from being too low and affecting the siphon atomization of the liquid medicine.

[0043] Optionally, as Figure 1-3 shown, a first interface pipe 221 is provided at the bottom end of the cup body 22, and the first interface pipe 221 is detachably connected to the first end of the oxygen connection pipe 3. By providing the first interface pipe 221, it is convenient to connect the cup body 22 and the oxygen connection pipe 3. Specifically, the cup lid 21 covers the outside of the cup body 22 and is threadedly connected to the cup body 22.

[0044] Optionally, as Figure 1 shown, the oxygen connection pipe 3 includes a first connector 31, a hose 32, and a second connector 33. The first connector 31 and the second connector 33 are respectively fixedly provided at both ends of the hose 32, and the first connector 31 is detachably connected to the first interface pipe 221. The second connector 33 is used to connect to the oxygen meter interface at the central oxygen supply.

[0045] Optionally, as Figure 1 and Figure 2 shown, a second interface pipe 211 is provided at the top end of the cup lid 21, and the second connection pipe 15 is detachably connected to the third port 14. By providing the second interface pipe 211, it is convenient to connect the cup lid 21 and the T-shaped connection pipe 1. Specifically, the top end of the second interface pipe 211 is located inside the third port 14 and is threadedly connected to the third port 14.

[0046] Usage method of the multi-purpose nebulizer for tracheotomy patients provided in this embodiment:

[0047] Unscrew the cup cover 21 from the cup body 22, add the prepared liquid medicine to the 2 / 3 capacity of the cup body 22, and then screw on the cup cover 21 (or directly add the prepared liquid medicine into the cup body 22 through the medicine adding port 212); Connect one end of the oxygen connecting pipe 3 to the oxygen supply place, and the other end to the bottom of the atomizing cup 2. During use, pay attention to keeping the atomizing cup 2 in a vertical state. Turn on the oxygen supply switch, and the compressed oxygen flows at a high speed through the oxygen pipe. When the oxygen flows out of the oxygen pipe and through the air outlet holes of the nozzle 23, since the nozzle 23 is conical, when the oxygen sprays out from the nozzle 23 with a gradually decreasing cross-sectional area, a negative pressure is generated at the air outlet holes of the nozzle 23, and the liquid medicine flows from the bottom of the nozzle 23 along the flow passage 10 to the top of the nozzle 23. The liquid medicine is impacted by the high-speed flowing oxygen to generate a medicine mist. At the same time, the medicine mist enters the first pipe section 241 of the mist outlet pipe 24 along with the oxygen and is mixed into a more uniform medicine mist in the first pipe section 241. The medicine mist enters the patient's respiratory tract along the second pipe section 242 of the mist outlet pipe 24 and the T-shaped connecting pipe 1. Since the corrugated pipe can be bent to any angle, the tracheotomy cannula can be connected to the T-shaped connecting pipe 1 without tilting the atomizing cup 2, preventing the atomizing cup 2 from tilting and affecting the flow of the liquid medicine along the flow passage 10 to the air outlet holes of the nozzle 23 to generate a medicine mist, ensuring the conversion rate of the liquid medicine into a medicine mist, and thus ensuring the atomizing effect.

[0048] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
