Description

Technical Field

[0001] The invention relates to the field of sputum aspirators, and more particularly to a safe sputum aspirator for emergency internal medicine. Background Art

[0002] Aspirator is a medical device mainly used to remove secretions or foreign objects from the patient's respiratory tract to keep the respiratory tract unobstructed. The aspirator inserts a suction tube into the oral cavity, nasal cavity, artificial airway, etc., and uses the negative pressure principle to suck out the secretions from the respiratory tract, thereby keeping the respiratory tract unobstructed. Aspirator is mainly used to improve the situation of excessive sputum or inability to cough up sputum caused by diseases such as lung infection, chronic obstructive pulmonary disease, and bronchial asthma; using aspirator can reduce sputum accumulation, relieve breathing difficulties, and help prevent complications such as aspiration pneumonia, atelectasis, and suffocation.

[0003] When suctioning sputum, the upper respiratory tract is usually suctioned first, that is, the sputum in the mouth is sucked first, and then the sputum in the nasal cavity is sucked clean; this is because the lower respiratory tract is relatively sterile, while the upper respiratory tract is bacteria-free; if the upper respiratory tract is suctioned first, the suction tube may carry bacteria, and then the lower respiratory tract is suctioned, it is possible to bring the bacteria in the upper respiratory tract to the lower respiratory tract, causing respiratory tract infection; therefore, the order of suctioning sputum is first upper and then lower to avoid cross infection;

[0004] The upper respiratory tract is the gateway for air and food to enter the body, so it is more likely to be exposed to pollutants such as dust, bacteria, and viruses in the air. When a patient is sick, the upper respiratory tract is prone to residual solid particles and a large number of bacteria due to coughing and rumination. The use of sputum suction usually involves cleaning the upper respiratory tract first, and then extending the tube into the lower respiratory tract. This will cause the suction tube to carry bacteria in the upper respiratory tract to the lower respiratory tract, which may not only cause lower respiratory tract infection or even lung infection, but may also cause solid particles to be pushed into the lower respiratory tract, causing blockage of the lower respiratory tract and suffocation of the patient. Even if the particles are small and will not block the trachea, they will cause the patient to cough violently and thus cause certain obstacles to sputum suction.

[0005] In view of this, in view of the above-mentioned deficiencies, the present invention improves and optimizes the sputum suction device in the prior art and develops a safe sputum suction device for emergency internal medicine. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This scheme can prevent sputum from adhering to the second suction tube by setting the first suction tube and the second suction tube, thereby preventing bacteria in the upper respiratory tract from infecting the lower respiratory tract. The first suction tube does not directly enter the lower respiratory tract, and the first suction tube and the second suction tube are separated. The first suction tube has a larger diameter and can absorb solid particles, preventing solid particles from being pushed into the lower respiratory tract and causing suffocation or severe coughing of the patient, thereby increasing protection for the patient, reducing the risk of infection, and reducing the accident rate.

[0021] 2. This solution sets up a protective component. During normal operation, the pressure of the spring can be adjusted by rotating the protective shell, so as to change the size of the protection threshold according to the suction force of the host. When the internal pressure of the pipeline increases, it can open automatically to prevent the patient from suffocating and improve the safety of the device. It is highly applicable whether facing conscious or unconscious patients.

[0022] 3. This scheme sets up an auxiliary device. When encountering an epileptic patient, it can prevent the epileptic patient from biting the tube, and on the other hand, it can prevent the epileptic patient from biting the tongue. The patient's mouth is supported to facilitate continuous suction operation, increase the practicality of the device, and when used with a tongue depressor, the tongue can be blocked on the lower jaw when the tube is inserted, thereby improving the tube insertion efficiency and preventing the patient's tongue from twisting, causing the tube wall to be squeezed and thus reducing the suction effect.

[0023] 4. In this scheme, by setting the first auxiliary ring, the first suction tube stays inside the patient's upper respiratory tract, which can not only support the upper respiratory tract to prevent foreign objects from blocking the upper respiratory tract, but also there is no need to remove the first suction tube after a suction operation. Frequent suction operations can be achieved by repeatedly pushing the second suction tube, thereby reducing the probability of the intubation tube touching sensitive positions such as the patient's epiglottis, reducing the patient's pain, and eliminating the need for repeated intubation and extubation. While reducing the tediousness of the work, it can also increase the patency of the respiratory tract and prevent foreign objects from blocking it, making suction work for critically ill patients easier.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 9 A safe sputum suction device for emergency internal medicine comprises a main unit 1, which is used to generate negative pressure to suck sputum. A sputum storage tank 2 is detachably installed on one side of the main unit 1. The output end of the sputum storage tank 2 is connected to the suction end of the main unit 1 through a first main pipe 3. A filter 4 for filtering sputum is installed on the first main pipe 3. The input end of the sputum storage tank 2 is detachably connected to a second main pipe 5. A distributor 6 is detachably installed on the end of the second main pipe 5 away from the sputum storage tank 2. A first sputum suction tube 7 is detachably installed on the end of the distributor 6 away from the second main pipe 5. A second sputum suction tube 8 is installed on one side of the distributor 6. An auxiliary device 9 is detachably installed on the outside of the distributor 6.

[0037] In actual use, the host 1 has a motor capable of generating negative pressure inside, and the host 1 also has a knob for adjusting suction and a pressure display gauge. When suctioning the patient, first take a clean sputum storage tank 2 and install it on the side of the host 1, then insert one end of the first main pipe 3 into the output end of the sputum storage tank 2, insert the other end of the first main pipe 3 into the suction end of the host 1, and then insert one end of the second main pipe 5 into the input end of the sputum storage tank 2, then take a clean manifold 6 and insert it into the other end of the second main pipe 5, wait for the manifold 6 to be installed, and then The first suction tube 7 is also connected to the distributor 6, and then the main unit 1 is opened, and the second suction tube 8 is pulled to the end position. At this time, the first suction tube 7 is used to absorb physiological saline to observe whether the device is tightly connected to prevent leakage of the device. After waiting for the inspection to be completed, the patient's mouth is opened. If there is a foreign body in the mouth, it needs to be cleaned, and then the first suction tube 7 is slowly inserted into the patient's mouth, and then the first suction tube 7 is continuously inserted into the pharynx and larynx. The pharynx and larynx belong to the upper respiratory tract, which is the gateway for air and food to enter the body. Therefore, they are more likely to be exposed to pollutants such as dust, bacteria, viruses in the air, and when the patient is sick, the upper respiratory tract is prone to residual solid particles and a large number of bacteria due to coughing and rumination. The use of sputum suction usually involves cleaning the upper respiratory tract first, and then extending the tube into the lower respiratory tract. This will cause the suction tube to carry the bacteria in the upper respiratory tract to the lower respiratory tract, which may not only cause lower respiratory tract infection or even lung infection, but may also cause solid particles to be pushed into the lower respiratory tract, causing blockage of the lower respiratory tract and suffocation of the patient. Even if the particles are small and will not block the trachea, they will cause the patient to cough violently and thus cause a certain obstacle to sputum suction.

[0038] Therefore, the device is provided with a second sputum suction tube 8. When the upper respiratory tract is cleaned, the second sputum suction tube 8 is located at the end position. At this time, the second sputum suction tube 8 is in a closed state, and sputum and debris will enter the interior of the sputum storage tank 2 through the first sputum suction tube 7, the manifold 6, and the second main pipe 5. At this time, the second sputum suction tube 8 does not contact the sputum, so it will not be contaminated. When the upper respiratory tract is cleaned, the manifold 6 is fixed, and then the second sputum suction tube 8 is pushed, and the second sputum suction tube 8 is continuously pushed into the patient's lower respiratory tract. When the second sputum suction tube 8 enters the patient's lower respiratory tract, the second sputum suction tube 8 is in a connected state with the manifold 6. At this time, sputum will pass through the second suction tube 7, and the sputum will enter the lower respiratory tract through the second suction tube 7. The sputum tube 8 enters the interior of the distributor 6 and is sucked into the interior of the sputum storage tank 2 through the second main pipe 5, thereby separating the pipes passing through the upper respiratory tract and the lower respiratory tract. Because the second sputum suction tube 8 fits with the inner wall of the first sputum suction tube 7 when pushed, it can prevent sputum from adhering to the second sputum suction tube 8, thereby preventing bacteria in the upper respiratory tract from infecting the lower respiratory tract. The first sputum suction tube 7 does not directly enter the lower respiratory tract, and the first sputum suction tube 7 has a larger diameter and can absorb solid particles, preventing solid particles from being pushed into the lower respiratory tract to cause suffocation or severe coughing of the patient, thereby increasing protection for the patient, reducing the risk of infection, and reducing the accident rate.

[0039] The manifold distributor 6 includes a first shell 61, a connector 62 is fixedly installed at one end of the first shell 61, a second shell 63 is integrally formed at one end of the first shell 61 away from the connector 62, a branch shell 64 is integrally formed on one side of the first shell 61, the branch shell 64 is connected to the interior of the first shell 61, the connector 62 is inserted at the end of the second main pipe 5, and the first suction tube 7 is inserted inside the second shell 63.

[0040] The inner diameters of the first shell 61 and the second shell 63 are different. The inner diameter of the second shell 63 is larger than the inner diameter of the first shell 61. The inner diameter of the branch shell 64 is the same as the inner diameter of the first shell 61. The connector 62 is provided with a plurality of grooves for increasing the connection strength, thereby increasing the connection sealing and connection strength between the connector 62 and the second main pipe 5.

[0041] The second sputum suction tube 8 includes a branch hose 81, one end of which is fixedly installed with a probe 82, the probe 82 is a ring-shaped structure, the end of the branch hose 81 away from the probe 82 is integrally formed with a connecting tube 811, the connecting tube 811 is provided with a leakage groove 813, the end of the connecting tube 811 away from the branch hose 81 is fixedly installed with a clamping ring 814, the external sliding sleeve of the connecting tube 811 is provided with a closed shell 83, the leakage groove 813 and the clamping ring 814 are both located inside the closed shell 83, a plurality of L-shaped blocks 85 distributed in a ring are fixedly installed on one side of the closed shell 83, and a plurality of clamping grooves 65 corresponding to the L-shaped blocks 85 are provided at the end of the branch shell 64 away from the first shell 61.

[0042] When suctioning the patient's upper respiratory tract, the probe 82 is located inside the branch shell 64. At this time, the second suction tube 8 is in a sealed state, so the sputum will be sucked into the inside of the branch tube 6 by the first suction tube 7, and then sucked into the inside of the sputum storage tank 2 by the second main tube 5, and will not pass through the probe 82. When suctioning the patient's lower respiratory tract, the second suction tube 8 is pushed. At this time, the probe 82 enters the inside of the first shell 61, and the second suction tube 8 is continuously pushed so that the branch tube 81 enters the inside of the first shell 61. At this time, the probe 82 extends from the position of the second shell 63, and the second suction tube 8 is continuously pushed so that the probe 82 enters the lower respiratory tract of the patient. At this time, the connecting tube 811 enters the interior of the first shell 61, and then the connecting tube 811 is connected to the interior of the first shell 61 through the leakage groove 813. At this time, the sputum will enter the interior of the branch hose 81 through the probe 82, and then enter the distributor 6 from the leakage groove 813, and then be sucked into the interior of the sputum storage tank 2 by the second main pipe 5. When waiting for the second sputum suction tube 8 to enter the lower bronchus, the L-shaped block 85 is inserted into the interior of the card groove 65, and then the closed shell 83 is rotated to fix the closed shell 83 on the branch shell 64. At this time, the sputum suction operation can be performed on various positions of the lower respiratory tract by pulling back and forth. The clamp ring 814 is used to limit and maintain the sealing of the closed shell 83.

[0043] An end branch pipe 812 is fixedly installed on the end of the connecting pipe 811 away from the branch hose 81, and a threaded pipe 815 is fixedly installed on the end of the end branch pipe 812 away from the connecting pipe 811. A protective component 84 for preventing the patient from suffocating is installed on the threaded pipe 815. The protective component 84 includes a protective shell 841. A through hole 843 is opened on one side of the protective shell 841. The side of the through hole 843 away from the through hole 843 is sleeved on the outside of the threaded pipe 815 through a threaded fitting. A spring 842 is provided inside the protective shell 841. The spring 842 is rotatably installed on the threaded pipe 815. A sealing plate 844 for blocking the through hole 843 is fixedly installed on the end of the spring 842 away from the threaded pipe 815.

[0044] During the suction process, the patient is not always in a conscious state, especially when facing some emergency situations. The patient's condition is usually not very good and the patient may be in a coma. When the patient is conscious, if the patient has difficulty breathing due to solid particles blocking the pipe, the patient will have a greater resistance. However, when the patient is in a coma, it is impossible to determine whether the patient is suffocating, and the patient may suffocate easily due to improper operation.

[0045] Therefore, the device is provided with a protective component 84. When the inside of the pipeline is blocked by foreign matter, the pressure inside the pipeline will generate a large negative pressure under the suction of the host 1 and the suction of the patient's lungs. The negative pressure will be transmitted to the inside of the protective shell 841, and then the through hole 843 will be pushed by the external atmospheric pressure to open the through hole 843, and the patient can breathe through the protective component 84. During normal operation, the sealing plate 844 blocks the through hole 843 and does not affect the normal operation of the host 1. The pressure of the spring 842 can also be adjusted by rotating the protective shell 841, so as to change the size of the protection threshold according to the suction size of the host 1, thereby preventing the patient from suffocating and improving the safety of the device. It has high applicability whether facing conscious or comatose patients.

[0046] The auxiliary device 9 includes an upper tooth plate 91, a symmetrical lower tooth plate 92 is provided below the upper tooth plate 91, support rods 93 are fixedly installed at both ends of one side of the upper tooth plate 91 and the lower tooth plate 92, two symmetrical connecting members 94 are provided on the side between the upper tooth plate 91 and the lower tooth plate 92 close to the support rod 93, the support rod 93 is rotatably mounted on the corresponding connecting member 94, a tongue depressor 921 is fixedly installed on the side of the lower tooth plate 92 close to the support rod 93, and lifting plates 911 are rotatably installed on both sides of the upper tooth plate 91 and the lower tooth plate 92, and the two lifting plates 911 on the same side are hinged to each other. Screw rods 97 are provided on both sides between the upper tooth plate 91 and the lower tooth plate 92, and a rotating joint 912 is rotatably installed on the side of a lifting plate 911 on the same side. Screw rods 97 are provided on both sides between the upper tooth plate 91 and the lower tooth plate 92. The screw rods 97 are clamped in the middle of the rotating joint 912 through thread holes. End plates 941 are fixedly installed on the sides away from each other of the two connecting parts 94, one end of the screw rod 97 is rotatably installed on the end plate 941, and a rotating sleeve 971 is fixedly installed on the end of the screw rod 97 away from the end plate 941. The rotating sleeve 971 can be but is not limited to the hexagonal sleeve commonly used on the market.

[0047] When epilepsy occurs, it is often accompanied by convulsions, foaming at the mouth, and rumination. When these phenomena occur, vomitus and foam may block the respiratory tract, causing the patient to suffocate. Conventional means cannot be used to suction sputum in patients with epilepsy because they may bite the tube, vomit continuously, etc. Suctioning sputum is not only about sucking out sputum, but also a general term for clearing the patient's respiratory tract.

[0048] Therefore, the present device is provided with an auxiliary device 9. When encountering an epileptic patient, the auxiliary device 9 can be inserted into the patient's oral cavity, and then the rotating sleeve 971 is rotated. The rotating sleeve 971 drives the screw rod 97 to rotate, and then the rotating joint 912 is driven to move along the screw rod 97. At this time, the upper tooth plate 91 and the lower tooth plate 92 will be displaced away from each other under the drive of the lifting plate 911, and then the patient's mouth will be stretched open. Then the divider 6, the first suction tube 7, and the second suction tube 8 are inserted into the patient's respiratory tract between the upper tooth plate 91 and the lower tooth plate 92. On the one hand, it can prevent the epileptic patient from biting the tube, and on the other hand, it can also prevent the epileptic patient from biting the tongue. The patient's mouth is supported to facilitate continuous suction operation, thereby increasing the practicality of the device. In addition, when used with the tongue depressor 921, the tongue can be fixed on the lower jaw when the tube is inserted, thereby improving the efficiency of tube insertion.

[0049] A fixing sleeve 931 is fixedly installed on the outer surface of the four support rods 93, a first auxiliary ring 95 is provided in the middle position of the four support rods 93, a first rotating member 932 is rotatably installed on the side of the fixing sleeve 931 close to the first auxiliary ring 95, two second rotating members 934 corresponding to the first rotating member 932 are rotatably installed on both sides of the first auxiliary ring 95, a connecting rod 933 is rotatably connected between the multiple second rotating members 934 and the first rotating member 932, and a second auxiliary ring 96 is fixedly installed between the two connecting members 94.

[0050] During the suction operation, because the tube needs to be inserted into the upper and lower respiratory tracts, it is easy to touch the patient's epiglottis and tongue root and other sensitive parts during the process. When these sensitive parts are touched, the patient may vomit or have a severe resistance reaction. When facing some emergency patients who have lost the ability to cough up phlegm, medical staff need to frequently perform suction operations on them. Repeated suctioning, intubation, and extubation will increase the patient's pain and lead to suffocation, vomiting, and increased rejection reactions.

[0051] When the upper tooth plate 91 and the lower tooth plate 92 are away from each other, because the two connecting rods 933 on the same side are in a V shape, when the support rod 93 is driven to separate, the connecting rod 933 will drive the first rotating member 932 to rotate. At this time, the first auxiliary ring 95 is driven to move toward the direction of the upper tooth plate 91. When the upper tooth plate 91 and the lower tooth plate 92 are stretched to the maximum position, the screw rod 97 is rotated in the opposite direction to make the upper tooth plate 91 and the lower tooth plate 92 fit each other. At this time, the first auxiliary ring 95 passes the equilibrium position, and then when the upper tooth plate 91 and the lower tooth plate 92 are close to each other, the first auxiliary ring 95 will continue to move between the upper tooth plate 91 and the lower tooth plate 92. At this time, the second shell 63 is placed on the first auxiliary ring 95, and the outer part of the support rod 93 It has a limit block, and then controls the upper tooth plate 91 and the lower tooth plate 92 to continue to approach until the upper tooth plate 91 and the lower tooth plate 92 bite the first auxiliary ring 95. At this time, the second shell 63 is clamped by the upper tooth plate 91 inside the first auxiliary ring 95, and then the first suction tube 7 stays inside the patient's upper respiratory tract, which can not only support the upper respiratory tract to prevent foreign objects from blocking the upper respiratory tract, but also there is no need to remove the first suction tube 7 after a suction operation. Frequent suction operations can be achieved by repeatedly pushing the second suction tube 8, reducing the probability of the intubation tube touching sensitive positions such as the patient's epiglottis, reducing the patient's pain, and eliminating the need for repeated intubation and extubation. While reducing the tediousness of the work, it can also increase the patency of the respiratory tract and prevent foreign objects from blocking it, making critically ill patients more comfortable.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
