Description

Technical Field

[0001] The present invention relates to the technical field of surgical sputum suction devices, in particular to a surgical sputum suction device for neonates. Background Art

[0002] When newborns have symptoms such as breathing difficulties, wheezing, and throat gurgling, suctioning is required, or newborns at risk of respiratory diseases need preventive suctioning, so a neonatal suction device is needed. Suction devices can be electric or manual. They generate negative pressure to suck out sputum and secretions in the respiratory tract. They are mainly used to remove sputum, mucus and other secretions in the respiratory tract. For patients who need to eliminate respiratory secretions.

[0003] When suctioning a newborn, the newborn is easily moved due to stimulation, requiring multiple medical staff to control the newborn. The depth of the suction tube inserted into the newborn's mouth needs to be precisely controlled to avoid ineffective sputum removal due to being too shallow, or damage to the newborn due to being too deep. In addition, the oral intubation operation should be slow to avoid irritating the throat. Rapid insertion may cause a strong throat reflex, leading to coughing, nausea, vomiting and other discomfort reactions, increasing the patient's pain. However, due to the newborn's movement when stimulated, medical staff cannot maintain a slow and uniform speed to insert the suction tube into the newborn's mouth, resulting in irritation to the newborn's mucosa, further increasing the difficulty of the suction operation. In addition, the use of existing devices requires a lot of manpower. Therefore, the present application provides a newborn surgical suction device to meet the needs. Summary of the Invention

[0015] Optionally, the slide groove is a T-shaped groove, the sliding block is a T-shaped block, a mounting opening is provided at one end of the slide groove, and a second guide portion is provided at the top of the mounting opening.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up the nasal protection component and the limiting buffer mechanism, not only can the limiting plate and the nipple head be used to simulate the pacifier, reducing the resistance reaction of the newborn when receiving suction, thereby reducing the possibility of the newborn moving around and crying during the suction process, but also during the suction operation, the nasal protection component is used to protect the nose of the newborn. Because the immune system of the newborn is not fully developed, they are susceptible to infection. Therefore, this part is designed to prevent bacteria or other pathogens from entering the newborn's throat from the nose when the vacuum chamber is opened for suction operation. The nasal protection component can also protect the newborn's mucosa. Because the nasal mucosa of the newborn is very delicate and easily stimulated and damaged by the external environment, this part can serve as a barrier to protect the nasal mucosa from direct stimulation and damage by the suction tube. In addition, the limiting buffer mechanism can also guide, buffer and limit the insertion operation of the suction tube. The use of the limiting plate and the nipple head can further reduce the stimulation of the suction tube end to the newborn. The coordination between the structures can well use the suction tube body to be inserted to an appropriate depth, thereby ensuring effective suction of sputum. In addition, the above structure is relatively simple, and is relatively convenient and quick to use and operate, and the practicability of the device is good.

[0018] By arranging a disinfectant wipe and a limit frame in the nose protection component, the shapes of the limit frame and the disinfectant wipe are adapted to the shape of the side of the newborn's nose close to the nose tip, the limit frame is made of rubber material, the outer wall edge of the limit frame is arc-shaped, and the shape of the first weakened part on the limit frame is adapted to the shape of the newborn's nostril. By attaching the disinfectant wipe to the newborn's nose and making the thinner first weakened part located at the newborn's nostril, when the limit piece is brought close to the newborn's mouth, the limit frame is also brought close to the newborn's nose. When the pacifier head is inserted into the newborn's mouth, the limit frame is pressed on the disinfectant wipe at the same time. The coordinated use of the structures makes the suction operation more effective, and the coordinated use of the structures effectively makes the use effect of the nose protection component better, and the structure is simple and easy to use.

[0019] By providing a front-end pressing piece, a rear-end pressing piece and a first connecting piece in the nose protection component, not only can the front-end pressing piece be used to press the side of the disinfectant wipe close to the limiting piece, and the rear-end pressing piece can be used to press the side of the limiting frame away from the limiting piece, but the first connecting piece can also be used to enhance the stability of the limiting frame and further press the top of the disinfectant wipe. When the front-end pressing piece, the rear-end pressing piece and the first connecting piece are used in conjunction, the limiting frame can more stably limit the disinfectant wipe to the nose of the newborn, and there is no need for medical staff to manually limit the disinfectant wipe to the desired position. The coordinated use of the structures effectively makes the use of the nose protection component better, and the structure is simple and easy to use.

[0020] By providing a guide plate and a guide auxiliary plate in the limiting buffer mechanism, not only can the guide plate and the guide auxiliary plate be formed into an integrated structure, the connection between the guide plate and the guide auxiliary plate is tighter and the stability is better, and the guide plate is made of plastic material, and lightweight grooves are equidistantly provided on the guide auxiliary plate. The cost of the plastic material is low, and the plastic material itself has good deformation ability. With the use of the lightweight groove, the guide auxiliary plate is easily deformed when it is subjected to the extrusion force formed by the suction tube body passing through the guide auxiliary plate, thereby causing the suction tube body to slowly pass through the guide auxiliary plate, that is, the guide auxiliary plate can be used to limit and buffer the insertion action of the suction tube body, and a second weakening portion is provided on the side of the guide plate close to the top outer wall of the limiting plate, and a third weakening portion is provided on the side of the guide plate close to the inner wall of the first channel, thereby making the guide plate and the guide auxiliary plate have better deformation ability. The coordinated use of the structures effectively makes the use effect of the nose protection component better, and the structure is simple and easy to use.

[0021] By arranging a physiological saline bag and absorbent cotton in the limiting buffer mechanism, the limiting part squeezes the physiological saline bag when deformed, causing the sealed opening at the bottom of the squeezed physiological saline bag to tear and unfold, and the physiological saline in the physiological saline bag leaks out and is absorbed by the absorbent cotton. At this time, when the suction tube body passes through the absorbent cotton, the absorbent cotton rubs against the outer wall of the suction tube body, which can quickly lubricate and disinfect the suction tube body, thereby making the suction tube body less irritating to the mucous membrane of the newborn, thereby reducing discomfort during intubation and suctioning. The inner diameter of the second channel and the absorbent cotton is equal to the outer diameter of the suction tube body, which can better guide and limit the suction tube body, and the coordinated use of the structures effectively makes the use effect of the limiting buffer mechanism better, and the structure is simple and easy to use.

[0022] By providing a reinforcement ring in the limit buffer mechanism, not only can the reinforcement ring be made of silicone material, the hardness of the reinforcement ring is greater than the hardness of the nipple, but the reinforcement ring is used to strengthen the stability of the internal channel of the nipple, preventing the channel from closing when the newborn sucks the nipple, thereby making it difficult for the suction tube body to move in the second channel. The coordinated use of the structures effectively makes the use of the limit buffer mechanism better, and the structure is simple and easy to use.

[0023] To sum up, this device can not only use the nose protection component and the limit buffer mechanism and the various components therein to soothe the newborn during the suction operation, but also the coordination between the structures can protect the newborn's nose, and can quickly lubricate and disinfect the suction tube body, so that the suction tube body will cause less stimulation to the newborn's mucous membrane, thereby reducing the discomfort during intubation and suctioning. In addition, the structure of this device is simple, and it is quick and easy to use. The production cost of the device is low, and the practicality is good, which is convenient for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a surgical suction device for neonates, comprising a suction device body 1, a storage box body 2 being installed on one side of the suction device body 1, a suction tube body 3 being installed on the side of the storage box body 2 away from the suction device body 1, a suction tube end 4 being provided at the bottom end of the suction tube body 3, a limiting plate 5 being installed on the top of the suction tube end 4, and a nipple head 6 being installed at the bottom of the limiting plate 5; a nose protection component, the nose protection component being used to protect the nose of the newborn during suctioning, and the nose protection component being connected to the limiting plate 5; a limiting buffer mechanism, the limiting buffer mechanism being used to limit, guide and buffer the suction tube body 3 during the process of inserting the suction tube body 3 into the mouth of the newborn, and the limiting buffer mechanism being connected to the limiting plate 5.

[0046] The suction device body 1 is a device body that uses negative pressure to suction sputum. This embodiment shows a manually operated suction device body 1, but the suction device body 1 is not limited to the form shown in this embodiment. It can also be electric. The working principle of the suction device body 1 is an existing mature technology, so it will not be described in detail here. By inserting the suction tube body 3 into the mouth of the newborn, and then operating the suction device body 1, the suction tube body 3 is used to suck out the sputum in the newborn's throat, and the sucked sputum is collected in the storage box body 2. During the process, the suction tube end 4 is in the newborn's throat, the nipple head 6 is in the newborn's mouth, and the limiting piece 5 is on the periphery of the newborn's mouth. The limiting piece 5 and the nipple are used. The head 6 simulates a pacifier, thereby reducing the resistance reaction of the newborn when receiving suction, and further reducing the possibility of the newborn moving around and crying during the suction process. In addition, during the suction operation, the nose protection component is used to protect the nose of the newborn. Because the immune system of the newborn is not fully developed, they are susceptible to infection. Therefore, this part is designed to prevent bacteria or other pathogens from entering the newborn's throat through the nose when the vacuum chamber is opened for suction operation. The nose protection component can also protect the newborn's mucosa. Because the nasal mucosa of the newborn is very delicate and easily stimulated and damaged by the outside world, this part can serve as a barrier to protect the nasal mucosa from direct stimulation and damage by the suction tube.

[0047] In addition, the limiting buffer mechanism can also guide, buffer and limit the insertion operation of the suction tube. The use of the limiting plate 5 and the nipple head 6 can further reduce the stimulation of the suction tube end 4 to the newborn. The coordination between the structures can well use the suction tube body 3 to be inserted to the appropriate depth, thereby ensuring effective suction of sputum. In addition, the above structure is relatively simple, and it is relatively convenient and quick to use and operate. The practicality of this device is good, the production cost is relatively low, and it is easy to promote and use. The specific structural composition and working principle of the above-mentioned nose protection component and limiting buffer mechanism are described in detail below.

[0048] Among them, the limiting piece 5 and the nipple head 6 are integrated, which makes the connection between the limiting piece 5 and the nipple head 6 tighter. The limiting piece 5 and the nipple head 6 are both made of latex material, which is soft, skin-friendly, non-toxic and harmless. It is generally used in the production and manufacturing of pacifiers. The outer wall edge of the nipple head 6 of the limiting piece 5 is arc-shaped, and the arc shape has no obvious edges and corners, which enhances the protectiveness of the limiting piece 5 and the nipple head 6 and reduces the stimulation of the limiting piece 5 and the nipple head 6 to the mouth of the newborn. The shape of the limiting piece 5 is adapted to the shape of the mouth of the newborn. Through the adapted shape design, the limiting piece 5 plays a good limiting and protective role on the mouth of the newborn, and the structure is simple. The coordinated use of the structures further makes the use effect of the device better.

[0049] like Figures 3 to 7As shown, the nose protection assembly includes a limiting frame 9 installed on the limiting piece 5, a front end pressing piece 10 is provided on the side of the limiting frame 9 close to the limiting piece 5, and the end of the front end pressing piece 10 close to the side of the limiting piece 5 is fixedly connected to the limiting piece 5, and a rear end pressing piece 11 is provided on the side of the limiting frame 9 away from the limiting piece 5, a first connecting piece 13 is provided on the top of the limiting frame 9, and a guide pressing piece 12 is provided on the bottom of the rear end pressing piece 11. A disinfectant wipe 7 is installed on the bottom of the limiting frame 9, and a first weakened portion 8 is provided on the side of the disinfectant wipe 7 close to the limiting piece 5, and the rear end pressing piece 11 is close to the guide pressing piece 1 2 is provided with a fourth weakened portion 29 on one side, the front end pressing piece 10, the rear end pressing piece 11, the guide pressing piece 12 and the first connecting piece 13 are an integrated structure together to form a limit frame 9, the shape of the limit frame 9 and the disinfection wet wipe 7 is adapted to the shape of the side of the newborn's nose close to the nose tip, the limit frame 9 is made of rubber material, the outer wall edge of the limit frame 9 is arc-shaped, the shape of the first weakened portion 8 is adapted to the shape of the newborn's nostril, by attaching the disinfection wet wipe 7 to the newborn's nose, and making the thinner first weakened portion 8 located at the newborn's nostril, when the limit piece 5 is close to the newborn When the nipple 6 is placed in the newborn's mouth, the limiting frame 9 is placed together to approach the newborn's nose. When the nipple 6 is inserted into the newborn's mouth, the limiting frame 9 is pressed on the disinfecting wet wipes 7 at the same time. When the rear end pressing piece 11 on the limiting frame 9 is close to the newborn's nose, the guide pressing piece 12 at the end of the rear end pressing piece 11 is used to guide the rear end pressing piece 11 when it is close to the newborn's nose to prevent the end of the rear end pressing piece 11 from scraping the newborn and causing discomfort. The front end pressing piece 10 is used to press the side of the disinfecting wet wipes 7 close to the limiting piece 5, and the rear end pressing piece 11 is used to press the side of the limiting frame 9 away from the limiting piece 5. At the same time, The first connecting piece 13 strengthens the stability of the limiting frame 9 and further presses the top of the disinfecting wet wipe 7. When the front-end pressing piece 10, the rear-end pressing piece 11 and the first connecting piece 13 are used in conjunction with each other, the limiting frame 9 can more stably limit the disinfecting wet wipe 7 to the nose of the newborn. There is no need for medical staff to manually limit the disinfecting wet wipe 7 to the required position. The coordinated use of the structures enables the limiting piece 5 and the nipple head 6 to soothe the newborn during the suction operation, and the disinfecting wet wipe 7 and the limiting frame 9 to protect the newborn's nose. In addition, the structure is simple and it is convenient and quick to use.

[0050] like Figures 8 to 12As shown, the limiting buffer mechanism includes a guide piece 17 installed on the limiting piece 5, and sliders 18 are fixedly connected to both sides of the bottom of the guide piece 17. A second connecting piece 19 is fixedly connected to the top of the guide piece 17, and a guide auxiliary piece 20 is fixedly connected to the bottom of the guide piece 17. A slide groove 16 that matches the shape of the slider 18 is opened on the top of the limiting piece 5, a first channel 14 is opened at the center of the limiting piece 5, and a second channel 15 is opened at the center of the nipple head 6. The diameter of the second channel 15 is smaller than the diameter of the first channel 14. A physiological saline bag 25 is set on the guide auxiliary piece 20, and a sealing port 26 is set at the bottom of the physiological saline bag 25. Figure 12 As shown, the sealing opening 26 is serrated, and an absorbent cotton 27 is installed at the bottom of the guide piece 17. By aligning the slider 18 with the opening of the slide groove 16 and inserting it, the slider 18 is rotated to install the slider 18 in the slide groove 16, and the guide piece 17 can be quickly installed on the limit piece 5 for use, and pinching the second connecting piece 19 by hand when installing and removing the guide piece 17 can be more convenient to operate. Before installing the guide piece 17, the absorbent cotton 27 is placed at the bottom of the first channel 14. Since the diameter of the second channel 15 is smaller than the diameter of the first channel 14, the bottom of the absorbent cotton 27 is limited by the top of the second channel 15 during installation and will not fall off from the first channel 14. Then, and by utilizing the setting of the guide auxiliary piece 20, the physiological saline bag 25 is put on it in advance before installing the guide piece 17, so that the physiological saline bag 25 can be installed in the second channel 15 together when the guide piece 17 is installed. The coordinated use between the structures can make the limiting buffer mechanism quickly installed on the limiting piece 5 for use, and disassembly is also relatively convenient.

[0051] Among them, a first guide portion 21 is provided on the top of the guide piece 17, and the guidance of the first guide portion 21 makes it easier and faster to insert the suction tube end 4 at the bottom of the suction tube body 3 into the first channel 14, and then the guide piece 17 is used to guide and limit the suction tube body 3. A limiting portion 22 is provided on the top of the guide auxiliary piece 20, and the setting of the limiting portion 22 is used to form an extrusion effect on the suction tube body 3, so that the suction tube body 3 can be slowly inserted into the mouth of the newborn. The guide piece 17 and the guide auxiliary piece 20 are integrally formed, so that the connection between the guide piece 17 and the guide auxiliary piece 20 is tighter and more stable. The guide piece 17 is made of plastic material, and lightweight grooves 31 are equidistantly provided on the guide auxiliary piece 20. The cost of the plastic material is low, and the plastic material itself has good shape. The guide auxiliary piece 20 is easy to deform when it is subjected to the extrusion force generated by the suction tube body 3 passing through the guide auxiliary piece 20, so that the suction tube body 3 can slowly pass through the guide auxiliary piece 20, that is, the guide auxiliary piece 20 can be used to limit and buffer the insertion action of the suction tube body 3. A second weakened portion 23 is provided on the side of the guide piece 17 close to the top outer wall of the limiting piece 5, and a third weakened portion 24 is provided on the side of the guide piece 17 close to the inner wall of the first channel 14. The arrangement of the second weakened portion 23 and the third weakened portion 24 further increases the deformability of the guide piece 17 and the guide auxiliary piece 20, so that the guide piece 17 and the guide auxiliary piece 20 are first bent and deformed from the second weakened portion 23 and the third weakened portion 24 under the action of external force.

[0052] like Figure 9 As shown, the saline bag 25 is installed in the first channel 14. In the initial state, the saline bag 25 is not squeezed, and the guide auxiliary sheet 20 is in an arc-shaped structure that bulges away from the saline bag 25. The saline bag 25 is sleeved on the bottom of the guide auxiliary sheet 20, and the outer wall of the side away from the guide auxiliary sheet 20 is in close contact with the inner wall of the first channel 14. When the upper limit portion 22 of the guide auxiliary sheet 20 is deformed, as shown in FIG. Figure 12The volume of the cavity formed between the guide auxiliary sheet 20 and the first channel 14 becomes smaller, so that the inner wall of the first channel 14 and the outer wall of the guide auxiliary sheet 20 squeeze the physiological saline bag 25, so that under the action of the squeezing force, the bottom side of the physiological saline bag 25 mounted on the bottom of the guide auxiliary sheet 20 is torn open. Due to the serrated sealing opening 26 pre-provided at the bottom of the physiological saline bag 25, the physiological saline bag 25 is more easily torn and unfolded when subjected to the squeezing force, and then under the influence of gravity, the physiological saline in the physiological saline bag 25 leaks out and flows toward the absorbent cotton 27 at its bottom, and is thereby absorbed by the absorbent cotton 27 made of a material with good water absorption. Since the absorbent cotton 27 has good water absorption and water collection capabilities, the physiological saline flowing out of the physiological saline bag 25 will not flow to other places. At this time, when the suction tube body 3 passes through the absorbent cotton 27, the absorbent cotton 27 rubs against the outer wall of the suction tube body 3, which can quickly lubricate and disinfect the suction tube body 3, thereby making the suction tube body 3 less irritating to the mucous membrane of the newborn, thereby reducing the discomfort during intubation and suctioning.

[0053] The inner diameter of the second channel 15 and the absorbent cotton 27 is equal to the outer diameter of the suction tube body 3, which can better guide and limit the suction tube body 3. A reinforcement ring 28 is installed in the second channel 15. The reinforcement ring 28 is made of silicone material. The hardness of the reinforcement ring 28 is greater than the hardness of the pacifier 6. The reinforcement ring 28 is used to strengthen the stability of the internal channel of the pacifier 6 to prevent the channel from closing when the newborn sucks on the pacifier 6, thereby making it difficult for the suction tube body 3 to move in the second channel 15. The chute 16 is a T-shaped groove, and the slider 18 is a T-shaped block. A mounting opening is provided at one end of the chute 16, and a second guide portion 30 is provided at the top of the mounting opening. By utilizing the shape design of the chute 16 and the slider 18, the slider 18 can be quickly and stably installed in the chute 16 for use, and the second guide portion 30 provided at the top of the mounting opening on one side of the chute 16 is used to guide the installation of the slider 18, further facilitating the installation operation of the slider 18. The coordinated use of the structures further makes the use effect of the limiting buffer mechanism better, and the structure is simple and practical.

[0054] The working principle of the technical solution provided by the present invention is as follows:

[0055] During use, first attach the disinfectant wipes 7 to the nose of the newborn, and make the thinner first weakened part 8 be located at the nostrils of the newborn, then install the absorbent cotton 27 to the bottom of the first channel 14, and the diameter of the second channel 15 is smaller than the diameter of the first channel 14, so that the bottom of the absorbent cotton 27 is limited by the top of the second channel 15 during installation and will not fall off from the first channel 14, then put the physiological saline bag 25 on the bottom of the guide auxiliary piece 20, then align the slider 18 with the opening of the slide groove 16, then insert the slider 18 into the slide groove 16 and rotate the slider 18 to install the slider 18 in the slide groove 16, and when the slider 18 is inserted into the slide groove 16, the second guide part 30 is used to guide the slider 18 to be installed in the slide groove 16 faster, and the guide auxiliary piece 20 and the physiological saline bag 25 are placed in the first channel 14, then the pacifier head 6 is inserted into the mouth of the newborn, and the limiting piece 5 is close to the mouth of the newborn.

[0056] At the same time, when the limiting piece 5 is brought close to the mouth of the newborn, the limiting frame 9 is also brought close to the nose of the newborn. When the nipple 6 is inserted into the mouth of the newborn, the limiting frame 9 is pressed on the disinfectant wipes 7 at the same time. When the rear end pressing piece 11 on the limiting frame 9 is close to the nose of the newborn, the guide pressing piece 12 at the end of the rear end pressing piece 11 is used to guide the rear end pressing piece 11 when it is close to the nose of the newborn to prevent the end of the rear end pressing piece 11 from scraping the newborn and causing discomfort. The front end pressing piece 10 is used to press the side of the disinfectant wipes 7 close to the limiting piece 5, and the rear end pressing piece 11 is used to press the limiting frame 9 The side away from the limiting piece 5 is pressed, and the first connecting piece 13 is used to enhance the stability of the limiting frame 9, and the top of the disinfecting wipe 7 is further pressed. When the front end pressing piece 10, the rear end pressing piece 11 and the first connecting piece 13 are used in conjunction with each other, the limiting frame 9 can more stably limit the disinfecting wipe 7 to the nose of the newborn. There is no need for medical staff to manually limit the disinfecting wipe 7 to the required position. The coordinated use of the structures enables the limiting piece 5 and the nipple 6 to soothe the newborn during the suction operation, and the disinfecting wipe 7 and the limiting frame 9 to protect the nose of the newborn.

[0057] Then, the suction tube end 4 at the bottom of the suction tube body 3 is inserted into the guide piece 17 from the top of the guide piece 17 along the guidance of the first guide part 21, and continues to be inserted downward into the guide auxiliary piece 20. Since the outer diameter of the suction tube end 4 is larger than the diameter of the upper limit portion 22 of the guide auxiliary piece 20, the suction tube body 3 squeezes the guide auxiliary piece 20 when passing through the guide auxiliary piece 20, and then the upper limit portion 22 of the guide auxiliary piece 20 squeezes the saline bag 25 when it is deformed, and then the sealing port 26 at the bottom of the squeezed saline bag 25 is torn and expanded, and the saline in the saline bag 25 leaks out and is absorbed by the absorbent cotton 27.

[0058] like Figure 9The saline bag 25 is installed in the first passage 14. In the initial state, the saline bag 25 is not squeezed. The guide auxiliary sheet 20 is in an arc-shaped structure that bulges away from the saline bag 25. The saline bag 25 is placed on the bottom of the guide auxiliary sheet 20, and the outer wall of the side away from the guide auxiliary sheet 20 is in close contact with the inner wall of the first passage 14. When the upper limit portion 22 of the guide auxiliary sheet 20 is deformed, as shown in FIG. Figure 12 The volume of the cavity formed between the guide auxiliary sheet 20 and the first channel 14 is reduced, so that the inner wall of the first channel 14 and the outer wall of the guide auxiliary sheet 20 squeeze the physiological saline bag 25. As a result, the physiological saline bag 25 on the bottom of the guide auxiliary sheet 20 is torn open due to the squeezing force. Due to the serrated sealing opening 26 pre-set at the bottom of the physiological saline bag 25, the physiological saline bag 25 is more likely to tear and unfold when subjected to the squeezing force. Then, under the influence of gravity, the physiological saline in the physiological saline bag 25 leaks out and flows toward the absorbent cotton 27 at the bottom thereof. , and thus absorbed by the absorbent cotton 27 made of a good water-absorbing material. Since the absorbent cotton 27 has good water absorption and water collection capabilities, the normal saline flowing out of the normal saline bag 25 will not flow to other places. At this time, the suction tube body 3 continues to be slowly inserted into the throat of the newborn. When the suction tube end 4 passes through the absorbent cotton 27, the absorbent cotton 27 rubs against the outer wall of the suction tube end 4, that is, the suction tube end 4 at the bottom of the suction tube body 3 can be quickly lubricated and disinfected, so that the suction tube body 3 will have less irritation to the mucous membrane of the newborn, thereby reducing the discomfort during intubation and suctioning.

[0059] In addition, the arrangement of the second weakened portion 23 and the third weakened portion 24 further increases the deformability of the guide piece 17 and the guide auxiliary piece 20, so that the guide piece 17 and the guide auxiliary piece 20 first bend and deform from the second weakened portion 23 and the third weakened portion 24 under the action of external force, so that the limiting portion 22 has a better squeezing effect on the saline bag 25 when deformed, so that the sealing port 26 at the bottom of the saline bag 25 can be torn and unfolded faster.

[0060] The guide piece 17 and the guide auxiliary piece 20 are integrally formed, so that the connection between the guide piece 17 and the guide auxiliary piece 20 is tighter and more stable. The guide piece 17 is made of plastic material, and a lightweight groove 31 is equidistantly provided on the guide auxiliary piece 20. The cost of the plastic material is low, and the plastic material itself has good deformation ability. With the use of the lightweight groove 31, the guide auxiliary piece 20 is easily deformed when it is subjected to the extrusion force formed by the suction tube body 3 passing through the guide auxiliary piece 20, so that the suction tube body 3 slowly passes through the guide auxiliary piece 20. The piece 20 can be used to limit and buffer the insertion action of the suction tube body 3. After the suction tube body 3 is inserted into the mouth of the newborn, the suction device body 1 is operated to use the suction tube body 3 to suck out the sputum in the newborn's throat, and the sucked sputum is collected in the storage box body 2. After the suction is completed, the suction tube body 3 is slowly pulled out, and then the nipple head 6 is taken out from the newborn's mouth, and the limiting frame 9 is removed from the newborn's nose, and finally the disinfectant wipes 7 are removed. The coordinated use between the structures further makes the use of the device better.
