Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, and in particular to an integrated suction and nebulization device for intensive care unit nursing. Background Technology

[0002] The Intensive Care Unit (ICU) is a dedicated area providing comprehensive treatment and care for critically ill patients. Suctioning and nebulization are common nursing interventions. Suctioning clears secretions from the airways, maintaining airway patency; nebulization transforms medications into fine droplets that act directly on the respiratory tract, improving lung function. In recent years, ICU nursing equipment has gradually evolved towards integration and intelligence, leading to the development of integrated suctioning and nebulization devices. These devices combine suctioning and nebulization functions, improving treatment efficiency and patient comfort. Equipped with an intelligent operating system, these devices automatically adjust treatment parameters based on the patient's specific condition, ensuring maximum therapeutic effect. Their advantages lie not only in efficient nebulization and simplified operation but also in reducing patient discomfort and improving the overall level of ICU care. With the increasing demand for refined nursing care from ICU patients, this equipment is expected to be further enhanced in the future through intelligent and automated technologies, enabling real-time monitoring of patient conditions and automatic adjustment of treatment parameters to achieve more precise and personalized care, driving ICU nursing towards greater efficiency, convenience, and intelligence.

[0003] A search revealed an existing patent (publication number: CN110368566A) disclosing an integrated device for sputum suction, oxygen delivery, and nebulization, belonging to the field of medical supplies. This device includes a mask, an oropharyngeal airway, a closed-loop suction tube, a fixing strap assembly, and an interface plug. The mask is connected to the oropharyngeal airway via the fixing strap assembly. The closed-loop suction tube is fixedly connected to the oropharyngeal airway. The interface plug is installed on the nebulizer interface located at the lower part of the mask. This invention integrates the oropharyngeal airway, the closed-loop suction tube, the mask for oxygen delivery, and the nebulizer into one unit. This avoids repeated procedures when treating comatose or critically ill patients, facilitating treatment and effectively preventing infection of medical personnel during the process.

[0004] However, in actual use of the above-mentioned method, the suction catheter needs to be pushed back and forth in the patient's trachea to ensure thorough suctioning. Although this can ensure thorough suctioning, this practice may have some adverse effects. Frequent pushing may cause mechanical damage to the patient's airway, especially for patients with fragile airways, which may lead to bleeding or infection. At the same time, the patient may feel severe discomfort, especially when awake, increasing anxiety and difficulty breathing. In addition, this operation may also bring the risk of cross-infection, especially if the equipment is not sterilized or the operation is improper. Nursing staff need a high level of skill to ensure the safety of the operation, otherwise it may lead to poor suctioning effect or airway obstruction. Most importantly, this manual operation increases the workload of nursing staff and may prolong the suctioning time, thereby affecting the efficiency and timeliness of treatment.

[0005] Therefore, the present invention provides an integrated suction and nebulization device for intensive care unit nursing. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example: Reference Figure 1-12 A nebulizer-assisted suction device for intensive care unit care, comprising a mask 1, and further comprising: The sealing ring 2 is fixed on the inner wall of the middle section of the mask 1. The mask 1 supports and fixes the sealing ring 2, and the sealing ring 2 seals the internal structure of the mask 1 and the sealing ring 2. A connecting component is located inside the sealing ring 2. The sealing ring 2 limits the connection component, and the connection component can be detached from the sealing ring 2. The engaging component is located inside the sealing ring 2. Its limiting end is rotatably connected to the slot 22 opened on the inner wall of the sealing ring 2, and the limiting end engages with the engaging end of the connecting component. The slot 22 limits the limiting end in the engaging component, and the limiting end engages and fixes the connecting component. The outer tube 4 is fixed inside the sealing ring 2 and passes through the outer tube 4. A second sliding groove 41 is opened on the outer side of the top of the outer tube 4. At the same time, a uniformly distributed through hole is opened on the outer side of one end of the outer tube 4 inside the patient's body. By opening the through hole on the outer side of one end of the outer tube 4, sputum can enter the interior of the outer tube 4 through the through hole. An air supply pipe 49 is fixed inside the outer pipe 4. The outer pipe 4 supports and fixes the air supply pipe 49 and passes through the outer pipe 4. At the same time, there is a gap between the air supply pipe 49 and the outer pipe 4. The suction assembly is located in the interlayer gap between the outer tube 4 and the air supply tube 49. Its suction end can slide in the interlayer gap. The air supply tube 49 supports the suction assembly, and the outer tube 4 separates the suction assembly from the trachea to prevent the suction assembly from causing mechanical damage to the trachea during suctioning. The gas delivery assembly has an air inlet end that passes through an outer tube 4 and is connected to an air delivery tube 49. The nebulized drugs and oxygen are gradually delivered to the air delivery tube 49 through gas delivery and are directly delivered into the trachea to reduce the patient's respiratory pressure. The pipeline connection assembly is connected to the suction assembly and the gas delivery assembly delivery ends at both ends by a first three-way valve 47 and a second three-way valve 411, respectively. The first three-way valve 47 and the second three-way valve 411 are connected through the pipeline connection assembly. A sealing component is located on the outside of the sealing ring 2. The suction component and the gas delivery component pass through the sealing component and are connected to the external suction device and the external nebulizer respectively. The sealing component seals the structure on the outside of the sealing ring 2 to prevent the external environment from directly contacting the internal structure. The exhaust pipe 21 is fixed on the outer wall of the sealing ring 2 located outside the mask 1 and is connected to the inside of the sealing ring 2. The sealing ring 2 supports and fixes the exhaust pipe 21. After the suction assembly, gas delivery assembly and auxiliary components are removed, the patient's exhaled exhaust gas can be discharged through the exhaust pipe 21. The oxygen tube 6 is detachably connected to the bottom of the L-shaped tube 5, and the other end is connected to an external oxygen source. After the suction assembly, gas delivery assembly and auxiliary components are removed, oxygen can be delivered into the mask 1 through the oxygen tube 6 and the L-shaped tube 5.

[0022] The connecting assembly includes a slider 31 that is slidably connected to a groove on the inner wall of the sealing ring 2. A connecting cover 3 is fixedly connected to the inner wall of the slider 31. The connecting cover 3 is slidably connected to the sealing ring 2. The groove on the inner side of the sealing ring 2 cooperates with the sealing ring 2 to lock and limit the connection cover 3 and the slider 31. The connecting cover 3 is fixedly connected to the outer wall of the outer tube 4 to fix the outer tube 4.

[0023] The locking assembly includes a limiting ring 23 rotatably connected to the inner side of the locking groove 22. The locking groove 22 limits the limiting ring 23, allowing it to rotate within the groove 22. A rotating ring 24 is fixedly connected to the outer wall of the limiting ring 23, supporting and fixing the rotating ring 24. A uniformly distributed handle 26 is fixedly connected to the outer wall of the rotating ring 24, supporting and fixing the handle 26. Simultaneously, rotating the handle 26 can drive the rotating ring 24 and the limiting ring 23 to rotate. The inner walls of the limiting ring 23 and the rotating ring 24 have first grooves 25 that are the same as the cross-section of the slider 31 and have the same position and number. The slider 31 can slide out from the groove inside the sealing ring 2 through the first grooves 25.

[0024] The first slide groove 25 has the same shape as the groove on the inner wall of the sealing ring 2, and the first slide groove 25 can be connected to the groove on the inner side of the sealing ring 2 by rotation. By setting the shape of the first slide groove 25 and the groove on the inner wall of the sealing ring 2 to be consistent, the slider 31 can slide freely in the first slide groove 25 and the groove on the inner wall of the sealing ring 2. By rotating the limiting ring 23 and the rotating ring 24, the first slide groove 25 is driven to rotate synchronously, so that the first slide groove 25 and the slider 31 are misaligned. Thus, the limiting ring 23 locks the slider 31 in the groove on the inner wall of the sealing ring 2, and it cannot move, thereby fixing the connecting cover 3.

[0025] The suction assembly includes a suction tube 42 slidably connected to the inner side of an outer tube 4, a second flexible tube 48 detachably connected to the end of a first three-way valve 47 away from the first flexible tube 46, which limits the suction tube 42 via the outer tube 4, and is supported and fixed by the first three-way valve 47. The end of the second flexible tube 48 away from the first three-way valve 47 is connected to an external suction device. The second flexible tube 48 connects the first three-way valve 47 and the external suction device. The suction tube 42 has evenly distributed suction ports 43 at the end inside the patient's body. The suction ports 43 are connected to through holes on the outer side of the outer tube 4 at the end inside the patient's body. Sputum in the trachea can enter the suction tube 42 through the through holes and suction ports 43 on the outer tube 4. A push-pull rod 44 is detachably connected to the outer wall of one end. The push-pull rod 44 is supported and fixed by the suction tube 42. When disassembling the suction assembly, the push-pull rod 44 must first be removed from the suction tube 42 before other components can be disassembled. The push-pull rod 44 passes through the outer tube 4 and is slidably connected to the outer tube 4. The outer tube 4 limits the push-pull rod 44. A connector 45 is fixedly connected to the top of the suction tube 42 on the side away from the suction port 43. A first flexible tube 46 is fixedly connected to the other end of the connector 45. The suction tube 42 and the first flexible tube 46 are connected through the connector 45. The end of the first flexible tube 46 away from the connector 45 is detachably connected to a first three-way valve 47. The first flexible tube 46 and the second flexible tube 48 are connected through the first three-way valve 47.

[0026] The gas delivery assembly includes a third hose 410 fixedly connected to one end of the outer side of the air delivery pipe 49, a fourth hose 412 fixed to the third hose 410 via the air delivery pipe 49 and detachably connected to the end of the second three-way valve 411 away from the third hose 410, the fourth hose 412 fixed via the second three-way valve 411, and the third hose 410 and the fourth hose 412 connected via the second three-way valve 411. The end of the fourth hose 412 away from the second three-way valve 411 is connected to an external nebulizer, and the end of the third hose 410 away from the air delivery pipe 49 is connected to the end of the second three-way valve 411. The fourth hose 412 is connected to the external nebulizer, thereby allowing the nebulized medicine along with oxygen to be delivered into the third hose 410.

[0027] The pipeline connection assembly includes a connecting pipe 413, with both ends of the connecting pipe 413 being detachably connected to the external interfaces on the same side of the first three-way valve 47 and the second three-way valve 411, respectively. The first three-way valve 47 and the second three-way valve 411 are connected through the connecting pipe 413.

[0028] The sealing assembly includes an L-shaped tube 5 fixed to one end of the outer side of the sealing ring 2. The sealing ring 2 supports and fixes the L-shaped tube 5. A first sealing cap 51 is threadedly connected to the top of the L-shaped tube 5 on the side away from the mask 1. The first sealing cap 51 is slidably connected to the first hose 46. The first sealing cap 51 seals the first hose 46 and the L-shaped tube 5 through the L-shaped tube 5. A fixing plate 52 is fixedly connected to the outer wall of the middle section of the L-shaped tube 5 on the side away from the mask 1. A second sealing cap 53 is threadedly connected to the inner side of the fixing plate 52. The second sealing cap 53 is slidably connected to the third hose 410. The second sealing cap 53 seals the third hose 410 and the L-shaped tube 5 through the second sealing cap 53.

[0029] A one-way valve is installed at the bottom of the inner side of the L-shaped tube 5. By installing a one-way valve at the bottom of the L-shaped tube 5, when oxygen is delivered into the L-shaped tube 5 through the oxygen tube 6 after the suction assembly, gas delivery assembly and auxiliary components are removed, the patient's exhaled waste gas is prevented from entering the oxygen tube 6 and contaminating the external oxygen source.

[0030] The lengths of the suction assembly and the air delivery tube 49 can be determined based on the length of the outer tube 4 inserted into the patient's body. Before using the suction assembly and the air delivery assembly, the length of the outer tube 4 needs to be determined first, and then the lengths of the suction assembly and the air delivery assembly are determined based on the length of the outer tube 4.

[0031] Specifically, when using this integrated suction and nebulization device for intensive care unit nursing: First, determine the length of the outer tube 4, then select a suction tube 42 of the corresponding length, then pass the outer tube 4 through the connecting cap 3, and fix the connecting cap 3 and the outer tube 4 together. Then, the corresponding first hose 46 is passed through the L-shaped tube 5, the first sealing cap 51 and connected to one end of the first three-way valve 47 respectively. Then, the second hose 48 and the connecting tube 413 are connected to the other two ports of the first three-way valve 47 respectively. Then, the first sealing cap 51 is connected inside the L-shaped tube 5 to complete the sealing between the first hose 46 and the L-shaped tube 5. The third hose 410 is passed through the L-shaped tube 5, the fixing plate 52 and the second sealing cover 53, and connected to one end of the second three-way valve 411. Then the other end of the connecting tube 413 and the fourth hose 412 are connected to the other two ports of the second three-way valve 411. After installation, adjust the first three-way valve 47 and the second three-way valve 411 to the corresponding positions so that the first hose 46 is connected to the second hose 48 and the third hose 410 is connected to the fourth hose 412. Then, align the slider 31 on the outside of the connecting cover 3 with the groove opened in the first slide groove 25 and the inner wall of the sealing ring 2, and insert the connecting cover 3 and the slider 31 into the sealing ring 2. Then, rotate the handle 26, which will drive the rotating ring 24 and the limiting ring 23 to rotate, thereby misaligning the first slide groove 25 and the slider 31 to complete the fixing of the connecting cover 3. When using the device, first insert the outer tube 4 into the patient's trachea and fix the mask 1 on the patient's face; The medication is atomized by an external nebulizer and oxygen is extracted and delivered into the fourth hose 412. During the process, the atomized medication moves synchronously. Then, the atomized medication and oxygen are delivered into the patient's trachea through the second three-way valve 411, the third hose 410 and the air delivery tube 49, and delivered to the lungs, thereby treating the lungs and trachea. The external suction device uses a second hose 48, a first three-way valve 47, a first hose 46, a connector 45, a suction tube 42, a suction port 43, and a through hole on the outside of the outer tube 4 to suction sputum from the trachea and simultaneously draw in and expel waste gas from the lungs. During the process, the suction tube 42 can be moved inside the outer tube 4 by pushing and pulling the push-pull rod 44. The suction port 43 is connected to the through holes at different positions, thereby suctioning sputum from different positions inside the trachea. In case of an emergency, if the air delivery tube 49 or the suction tube 42 is blocked, the first hose 46 and the third hose 410 can be connected by turning the first three-way valve 47 and the second three-way valve 411, thereby enabling the suction function through the fourth hose 412, or enabling the delivery of nebulized medicine through the second hose 48.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
