Description

Technical Field

[0001] The present invention relates to the technical field of critical pediatric respiratory tract treatment, and specifically refers to an atomization assistor for critical pediatric respiratory tract treatment. Background Art

[0002] In the medical field, the effective treatment of pediatric respiratory diseases is crucial. As an important treatment means for respiratory diseases, atomization treatment can convert liquid medicine into tiny particles, which can directly reach the lesion through breathing, improving the treatment effect. However, when critically ill children use existing atomizers, there are drawbacks:

[0003] When using an atomizer to treat respiratory diseases in critically ill children, due to the weak resistance and sensitive respiratory tract of children, the atomized medicine is likely to stimulate their respiratory tract, causing nausea and vomiting, resulting in the accumulation of vomit in the mouth. It is necessary to repeatedly remove the mask and spit out the dirt.

[0004] During the process of frequently removing the mask, not only will the atomized medicine be dispersed into the air, causing waste of medicine, but also the frequent interruption of treatment will seriously affect the treatment effect, and even may increase the risk of cross-infection due to improper operation.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above defects and provide an atomization assistor for critical pediatric respiratory tract treatment.

[0007] To solve the above technical problem, the technical solution provided by the present invention is: an atomization assistor for critical pediatric respiratory tract treatment, including: an atomizer body, the atomizer body is connected with a liquid medicine cup through a connecting pipe, and further includes:

[0008] An atomizer mask communicated with the connecting pipe, and a fixing pipe is obliquely connected to the atomizer mask;

[0009] A dirt collection device, the dirt collection device is composed of a guiding part arranged in the fixing pipe, a suction nozzle bag for collecting dirt, and a telescopic connecting part connecting the guiding part and the suction nozzle bag;

[0010] The guiding part includes a diversion pipe connected to the suction nozzle bag and a blowing nozzle detachably connected to the end of the diversion pipe. The patient discharges dirt into the suction nozzle bag through the blowing nozzle and the diversion pipe;

[0011] The telescopic connecting part includes a connecting ring, and both the diversion pipe and the suction nozzle bag are threadedly connected to the inner wall of the connecting ring;

[0012] The dirt collection device further includes a check mechanism disposed in the diversion pipe. The check mechanism includes a fixing ring fixedly connected to the inner wall of the diversion pipe. A ferromagnetic baffle is hinged on the inner wall of the fixing ring for isolating the backflow of dirt.

[0013] A further preferred solution of the present invention is that the diversion pipe is inserted into the fixing pipe, and an annular limiting plate for limiting the diversion pipe is fixedly connected to the diversion pipe.

[0014] A further preferred solution of the present invention is that the check mechanism further includes a rubber ring fixedly connected to the inner wall of the fixing ring. The baffle and the rubber ring are in contact with each other, and the baffle can only rotate unidirectionally away from the rubber ring through the rubber ring.

[0015] A further preferred solution of the present invention is that a groove corresponding to the position of the baffle is formed on the bottom wall of the fixing pipe, and a magnet block is fixedly connected in the groove. The magnet block generates a magnetic adsorption force on the baffle.

[0016] A further preferred solution of the present invention is that the telescopic connection part further includes an annular connection plate sleeved on the diversion pipe. A positioning ring is fixedly connected to the annular connection plate. The positioning ring is threadedly connected to the fixing pipe, and the positioning ring and the connection ring are connected by a return spring.

[0017] A further preferred solution of the present invention is that a large and a small corrugated pipe are also connected between the connection ring and the annular connection plate. The two corrugated pipes are coaxially arranged, and the return spring is located between the two corrugated pipes.

[0018] A further preferred solution of the present invention is that at least two elastic fixing bands are fixedly connected to the rear part of the atomizer mask.

[0019] Compared with the prior art, the present invention has the following advantages including but not limited to:

[0020] The present invention is provided with a dirt collection device. The patient can quickly discharge dirt through the inclined diversion pipe without removing the mask, reducing the interruption of treatment for child patients. At the same time, since the atomizer mask does not need to be removed, the situation of drug waste caused by the drug being emitted into the air is also reduced.

[0021] A telescopic connection part is also integrated in the dirt collection device, so that the position of the suction nozzle can be adjusted to make it fit more closely to the patient's mouth and nose, reducing the leakage of secretions. A check mechanism is provided to prevent the backflow of secretions and odors. The structure is simple and reliable, ensuring the treatment effect.

[0022] In addition, due to the synergistic effect of the telescopic connection part and the check mechanism, when a displacement operation is performed, the magnet block controls the baffle to open and close automatically without additional operation, improving the convenience of use.

[0038] Here, the exemplary embodiments will be described in detail, and the examples are shown in the attached Figure 1 to the attachedFigure 7 Among them. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] As described above, in the prior art, there is a frequent removal of the face mask, which not only causes the atomized drug to be dispersed into the air, resulting in drug waste, but also the frequent interruption of treatment will seriously affect the treatment effect, and even may increase the risk of cross-infection due to improper operation.

[0040] In view of this, the present invention provides an atomization assistance device, which is applied to the field of intensive pediatric respiratory tract treatment and solves the above problems. The present invention solves it in the following way:

[0041] First Embodiment:

[0042] Please refer to the attached Figure 1 As shown, this embodiment discloses an atomization assistor for intensive pediatric respiratory tract treatment. In this embodiment, it includes an atomizer body, a connecting tube 1 and a liquid medicine cup 2. Among them, the model of the atomizer body is OMRON NE-C28 / NE-C801. The connecting tube 1 is fixedly connected to the output port of the atomizer body, and the liquid medicine cup 2 is arranged on the connecting tube 1. It also includes an atomizer face mask 3. One end of the connecting tube 1 away from the atomizer body penetrates and is connected to the upper part of the front end of the atomizer face mask 3. In this way, when the atomizer body is started, the atomized liquid medicine will pass through the connecting tube 1 and the liquid medicine cup 2 and finally be transmitted into the atomizer face mask 3 for the patient's treatment.

[0043] View Figures 2 to 6 As shown, a fixing tube 4 penetrates and is connected to the lower part of the front end of the atomizer face mask 3. The fixing tube 4 gradually slopes downward from back to front on the atomizer face mask 3.

[0044] Then, a dirt collection device is arranged on the atomizer face mask 3. While the patient does not need to remove the atomizer face mask 3, the patient can spit out dirt outward. The dirt collection device is composed of a guiding part 5 communicated with the inside of the atomizer face mask 3, a suction nozzle bag 6 for collecting dirt and a telescopic connecting part 7. It should be noted that the suction nozzle bag 6 is a disposable and replaceable design, reducing the risk of cross-infection.

[0045] Among them, the function of the guiding part 5 is to guide the dirt discharged by the patient from inside the atomizer mask 3 to the outside. It includes a diversion tube 501 inserted into the fixed tube 4. It should be understood that the diversion tube 501 slides inside the fixed tube 4 by means of clearance fit. One end of the diversion tube 501 located inside the atomizer mask 3 is inserted with a nozzle 502. The front end of the diversion tube 501 is connected to the inlet of the suction nozzle bag 6. At this time, the nozzle 502, the diversion tube 501 and the suction nozzle bag 6 will form a complete dirt flow channel. Then, when in use, the nozzle 502 is abutted against the patient's mouth, and the patient spits the dirt into the diversion tube 501 through the nozzle 502. Since the diversion tube 501 is inserted into the fixed tube 4 and the fixed tube 4 is inclined downward, the dirt in the diversion tube 501 will accelerate and flow into the suction nozzle bag 6 under the influence of gravity.

[0046] At the same time, a circular limiting plate 503 is fixedly connected to the rear part of the outer wall of the diversion tube 501. The front part of the circular limiting plate 503 abuts against the rear end of the fixed tube 4. Under the influence of the circular limiting plate 503, the diversion tube 501 is limited within a limited range.

[0047] The function of the telescopic connection part 7 is to stably connect the suction nozzle bag 6 and the diversion tube 501 and adjust the position of the diversion tube 501 inside the fixed tube 4. It includes a connecting ring 701. The front part of the outer wall of the diversion tube 501 and the inlet part of the suction nozzle bag 6 are both threadedly connected to the inner wall of the connecting ring 701. Through the connecting ring 701, the diversion tube 501 and the suction nozzle bag 6 are always kept coaxial, and the inlet of the suction nozzle bag 6 is kept in contact with the diversion tube 501. Then, the dirt flowing out of the diversion tube 501 will directly flow into the suction nozzle bag 6 without leakage.

[0048] Next, a return spring 704 is fixedly connected to the rear end of the connecting ring 701. The rear end of the return spring 704 is fixedly connected to a circular connecting plate 702. It should be added that both the return spring 704 and the circular connecting plate 702 are sleeved on the periphery of the diversion tube 501. Then, a positioning ring 703 is fixedly connected to the rear end of the circular connecting plate 702. The positioning ring 703 is threadedly connected to the outer wall of the fixed tube 4. At this time, when the connecting ring 701 moves towards the circular connecting plate 702, the return spring 704 will be compressed, and at the same time, the connecting ring 701 can drive the diversion tube 501 to move together, so that the device can be adapted to more patients, make the nozzle 502 fit the patient's mouth, and reduce the situation of dirt leaking in the atomizer mask 3.

[0049] As the connecting ring 701 moves towards the annular connecting plate 702, it may pinch the patient's hand, especially the delicate fingers of children. To reduce the occurrence of this situation, two bellows 705 are provided between the connecting ring 701 and the annular connecting plate 702. The two bellows 705 are made of medical silicone. One of the two bellows 705 has a larger diameter and the other has a smaller diameter, and they are coaxially arranged. The front and rear ends of the bellows 705 are fixedly connected to the connecting ring 701 and the annular connecting plate 702 respectively. At this time, a closed accommodating cavity is formed among the two bellows 705, the connecting ring 701 and the annular connecting plate 702. The return spring 704 is arranged in the accommodating cavity. In this way, while reducing the occurrence of pinching hands, it can also reduce the leakage of atomized drugs.

[0050] In addition, compared with adult patients, child patients are more likely to move around due to curiosity or anxiety and fear. To reduce the occurrence of the situation where dirt flows back due to random movement, at the same time, when dirt accumulates in the suction nozzle bag 6, it will generate an odor. To reduce the situation where gas returns to the atomizer mask 3 and causes cross-infection, a check mechanism 8 is provided on the inner wall of the flow guide pipe 501 near the blowing nozzle 502.

[0051] Please pay special attention to Figure 7 As shown in the figure, the check mechanism 8 includes a fixed ring 801, a baffle 802 and a rubber ring 803. The fixed ring 801 is fixedly connected to the inner wall of the flow guide pipe 501. The baffle 802 is hinged to the middle of the top wall of the fixed ring 801. The hinge shaft of the baffle 802 is made of stainless steel and its surface is polished. The rubber ring 803 is fixedly connected to the rear part of the inner wall of the fixed ring 801. It should be noted that the baffle 802 and the rubber ring 803 are in contact, so that the baffle 802 can only rotate unidirectionally towards the side away from the rubber ring 803. At the same time, the inner diameter of the rubber ring 803 is smaller than the size of the baffle 802. Therefore, when the rubber ring 803 and the baffle 802 are in contact, the baffle 802 will be sealed with the rubber ring 803, thereby reducing the odor or the backflow of dirt into the atomizer mask 3. In addition, a layer of PTEE coating is applied to the surface of the baffle 802 to reduce the adhesion of dirt to the surface of the baffle 802.

[0052] Finally, at least two elastic fixing bands 9 are fixedly connected to the edge of the rear part of the atomizer mask 3, and the two elastic fixing bands 9 are detachably connected by buckles.

[0053] In summary, during use, cover the patient's face with the nebulizer mask 3, and fix the nebulizer mask 3 on the patient's head through the elastic fixing band 9. The atomized medicine generated by the operation of the nebulizer body is transmitted into the nebulizer mask 3 for the patient's treatment. When the patient produces saliva or sputum due to drug irritation, the patient / medical staff presses the connecting ring 701 to move it towards the side close to the annular connecting plate 702. The connecting ring 701 drives the diversion tube 501 and the mouthpiece 502 to move towards the patient's mouth. When the mouthpiece 502 touches the patient's mouth, the patient / medical staff stops pressing the connecting ring 701. Then the patient spits out the dirt through the leakage holes of the mouthpiece 502. The dirt passes through the rubber ring 803 and the diversion tube 501 in sequence, and finally flows into the suction nozzle bag 6.

[0054] Second Embodiment:

[0055] To further elaborate on the structure and operating principle of the above check valve mechanism 8 to solve the problem that the baffle 802 cannot be fixed and will rotate spontaneously due to the influence of gravity, the present invention provides another preferred embodiment.

[0056] Please refer specifically to the attached drawings of the specification Figure 7 In another preferred embodiment of the present invention, when the connecting ring 701 is in a static state, that is, when the annular limiting plate 503 abuts against the fixed tube 4, a groove 804 is provided on the fixed tube 4. A magnet block 805 is fixedly connected to the inner wall of the groove 804. The magnet block 805 made of sintered neodymium iron boron has the characteristics of anti-liquid corrosion and no pollution. It should be noted that the positions of the magnet block 805 and the groove 804 are close to the fixing ring 801. At the same time, it should also be noted that the bottom of the baffle 802 is made of iron material. Therefore, when the annular limiting plate 503 abuts against the fixed tube 4, the magnet block 805 can generate a magnetic adsorption force on the baffle 802, so that the baffle 802 can stably fit with the rubber ring 803 and will not rotate spontaneously due to the movement of the patient.

[0057] Combined with Embodiment 1 and Embodiment 2, when the patient / medical staff presses the connecting ring 701 and the guide tube 501 displaces towards the patient's mouth, the guide tube 501 will drive the baffle 802 to move together. And since the baffle 802 is magnetically attracted by the magnet block 805, the baffle 802 will always point to the magnet block 805 and thus rotate, allowing the dirt to smoothly pass through the rubber ring 803 and flow into the suction nozzle bag 6. When the sewage discharge is completed, the patient / medical staff releases the connecting ring 701. Under the influence of the return spring 704, the connecting ring 701 gradually returns to its original position. At the same time, the guide tube 501 will also drive the baffle 802 to slowly return to its original position. Since the position of the magnet block 805 remains unchanged, during the movement of the baffle 802 and under the magnetic influence of the magnet block 805, it will always point to the magnet block 805. Then the baffle 802 will rotate back to its original position, making the baffle 802 and the rubber ring 803 continue to fit.

[0058] Embodiment 3:

[0059] As described in Embodiment 1 and Embodiment 2, the guide tube 501 and the mouthpiece 502 on the guiding part 5 are detachably connected. At the same time, the guide tube 501 and the connecting ring 701 are threadedly connected, and the positioning ring 703 and the fixed tube 4 are threadedly connected. Thus, when the pediatric patient completes the atomization treatment, the telescopic connecting part 7 and the guide tube 501 can be quickly disassembled and thoroughly cleaned and disinfected accordingly. Then this device can be reused after disinfection.

[0060] Among them, for the used telescopic connecting part 7, first use a medical multi-channel cleaning machine to inject purified water at 80°C. Pulse parameters: the high-pressure period uses 0.5 MPa for 15 seconds, the low-pressure period uses 0.1 MPa for 5 seconds, and cycle 5 times to perform reverse pulse flushing on the telescopic connecting part 7. Then put the telescopic connecting part 7 into a high-frequency ultrasonic cleaning instrument, inject a cleaning solution with a multi-enzyme cleaning agent at 40°C, turn on the ultrasonic wave at 40 KHz, and focus on cleaning the folded parts of the corrugated pipe 705 for 20 minutes. Finally, put it into an ozone pretreatment cabinet at a temperature of 40°C and a humidity of 70% for disinfection treatment.

[0061] For the used mouthpiece 502, use a multi-enzyme cleaning solution to rinse the lumen of the mouthpiece 502, then put it into a 40 kHz medical ultrasonic cleaning machine for 8 minutes of ultrasonic cleaning, and finally put it into a pre-vacuum sterilizer for high-temperature sterilization.

[0062] For the guide tube 501 with the check mechanism 8, put a pre-heated multi-enzyme cleaning solution at 40°C into the guide tube 501, then rinse it with water at 45°C, then put it into a 40 kHz medical ultrasonic cleaning machine for ultrasonic cleaning, and after cleaning and disinfection, perform drying treatment on it.

[0063] So far, the advantages of the atomization assistor for treating severe pediatric respiratory tract provided by the present invention are as follows:

[0064] The present invention provides a dirt collection device on the atomizer mask 3, which can discharge the dirt spit out by children outside the atomizer mask 3 and collect it correspondingly without removing the atomizer mask 3.

[0065] Meanwhile, a telescopic connection part 7 is also arranged in the dirt collection device. During use, it can make the mouthpiece 502 fit more closely to the patient's mouth, reducing the leakage of dirt. In addition, a check mechanism 8 for preventing the backflow of dirt is arranged in the diversion tube 501. The structure is simple and can effectively prevent the backflow of dirt and odor, thus affecting the subsequent treatment situation.

[0066] In addition, the telescopic connection part 7 and the check mechanism 8 are used in cooperation. When the connection ring 701 on the telescopic connection part 7 pushes the diversion tube 501 to displace, the baffle 802 will be automatically opened and closed under the influence of the magnet block 805, without the need for additional operations, which is more convenient and fast.

[0067] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.

[0068] In addition, the electrical components appearing in this article are all electrically connected to the external main controller and 220V mains. And the main controller can be a conventional known device such as a computer for control. The detailed descriptions of known functions and known components are omitted in the specific implementation manners of the present disclosure. To ensure the compatibility of the device, the operation means adopted are consistent with the parameters of market instruments.
