Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically a sputum drainage and care device for lung infections. Background Technology

[0002] In the treatment of lung infections, timely and effective expectoration is crucial for patient recovery. Currently, commonly used sputum expectoration devices in clinical practice typically include a suction nozzle, a suction tube inserted into the patient's mouth and throat, a negative pressure mechanism to generate negative pressure, and a container for collecting sputum (such as a collection box).

[0003] However, existing sputum suction devices typically have a collection box attached to the suction nozzle, requiring cleaning of both the nozzle and the collection box after use. But sputum has strong absorbency, and the small internal space of the suction nozzle makes it difficult to completely remove residual sputum using conventional cleaning methods. This easily leads to bacterial growth, increasing the risk of cross-infection and seriously threatening patients' health.

[0004] Therefore, this application provides a sputum drainage nursing device for lung infections to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this application is to provide a sputum suction nursing device for lung infections, in order to solve the problems of sputum easily contaminating the suction mouthpiece in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution: a sputum suction nursing device for lung infection, comprising a suction nozzle, a negative pressure mechanism disposed at one end of the suction nozzle, a suction tube disposed at the other end of the suction nozzle for insertion into the patient's mouth and throat, and a collection bag for collecting sputum.

[0007] To prevent sputum from entering the suction mouthpiece: a collection bag is attached to the straw, and a three-way connector is fixedly inserted into the collection bag, communicating with the straw. The end of the three-way connector away from the straw is connected to the suction mouthpiece. The collection bag is a disposable storage bag. When the negative pressure mechanism is activated, negative pressure is generated inside the suction mouthpiece. When the straw is inserted into the patient's throat, sputum is drawn into the straw under this negative pressure. Because the collection bag is directly connected to the straw via the three-way connector, sputum flows along the straw into the three-way connector and then into the collection bag. Throughout this process, sputum does not come into contact with the internal space of the suction mouthpiece, effectively protecting it.

[0008] Preferably, the straw and the three-way connector are integrally molded. This integral design enhances the strength and sealing of the connection between the straw and the three-way connector. The strength ensures that the two will not separate during sputum suction due to suction or improper operation, guaranteeing the smooth progress of the sputum suction process. The sealing prevents sputum leakage from the connection during suction, avoiding pollution to the surrounding environment and further improving the reliability and hygiene of the sputum suction device.

[0009] Preferably, to facilitate the replacement of full collection bags during use: a nut is fixedly fitted onto the tee tube, and the nut is threaded onto the end of the collection bag. This threaded connection greatly facilitates medical personnel in replacing full collection bags during patient sputum expectoration.

[0010] Preferably, the negative pressure mechanism includes a cylinder communicating with the suction nozzle, a piston disposed within the cylinder, and a pull rod inserted into the end of the cylinder away from the suction nozzle and fixedly connected to the piston. Medical personnel or nurses can flexibly control the pulling speed and force of the pull rod according to actual conditions, thereby precisely adjusting the negative pressure inside the suction nozzle to meet the sputum expectoration needs of different patients. Compared to some complex electric negative pressure devices, it is lower in cost and can be used normally in places with inconvenient power supply, exhibiting better applicability and versatility.

[0011] Preferably, to prevent slippage between the hand and the lever, a handle is fixedly connected to the end of the lever furthest from the piston. The handle increases the contact area and friction between the medical staff's hand and the lever, effectively preventing slippage during lever pulling. This allows medical staff to operate the lever more stably and precisely, ensuring the negative pressure mechanism can continuously and stably generate the required negative pressure, providing a reliable guarantee for the successful completion of sputum suction, and improving the safety and accuracy of the operation.

[0012] Preferably, to prevent gas from being expelled from the cylinder into the patient's body when the piston moves towards the end closer to the suction nozzle, a first one-way valve is fixedly installed on the cylinder to allow gas from the suction nozzle to enter the cylinder. The first one-way valve effectively prevents gas from being mistakenly expelled from the cylinder into the patient's body when the piston moves towards the end closer to the suction nozzle. This function ensures the patient's safety during sputum clearance, avoiding problems such as choking, discomfort, or even respiratory damage that may be caused by abnormal airflow impacting the patient's airway, thus improving the safety and reliability of sputum clearance nursing procedures.

[0013] Preferably, to facilitate the discharge of gas from inside the cylinder, a second one-way valve is fixedly installed on the cylinder, communicating with the inside of the cylinder to discharge the gas. This second one-way valve facilitates the discharge of gas from inside the cylinder, ensuring the negative pressure mechanism can operate continuously and stably. During the continuous reciprocating motion of the piston, if the gas inside the cylinder cannot be discharged in time, it will lead to an internal pressure imbalance, affecting the generation and maintenance of negative pressure. The presence of the second one-way valve ensures smooth gas discharge, enabling the negative pressure mechanism to operate efficiently and stably, improving the overall performance and working efficiency of the sputum suction device.

[0014] This application significantly reduces the risk of sputum contamination of the suction nozzle by integrating the storage bag into the straw, making it a disposable item just like the straw. On one hand, this avoids bacterial growth due to incomplete cleaning, ensuring patient health and safety and reducing the possibility of cross-infection. On the other hand, it avoids discomfort for those cleaning sputum-contaminated suction nozzles, improving the operational experience for medical staff or nurses. Furthermore, the use of disposable components raises the overall hygiene standards of the care process, enhancing the patient's user experience. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] This embodiment provides a sputum expectoration nursing device for lung infections, such as... Figure 1-2 As shown, the nursing device includes a suction nozzle 1, a negative pressure mechanism 2 disposed at one end of the suction nozzle 1, a suction tube 3 disposed at the other end of the suction nozzle 1 for insertion into the patient's mouth and throat, and a collection bag 4 for collecting sputum.

[0021] To prevent sputum from entering the mouthpiece 1, a collection bag 4 is attached to the suction tube 3. A three-way tube 31, which is fixedly connected to the suction tube 3, is inserted into the collection bag 4. The end of the three-way tube 31 away from the suction tube 3 is inserted into the mouthpiece 1. The collection bag 4 is a disposable storage bag. This design greatly reduces the risk of the mouthpiece 1 being contaminated by sputum. On the one hand, it avoids bacterial growth due to incomplete cleaning, ensuring the health and safety of patients and reducing the possibility of cross-infection. On the other hand, it avoids discomfort for the person cleaning the mouthpiece 1 contaminated with sputum, improving the operational experience of medical staff or nurses. At the same time, the use of disposable parts also improves the hygiene standards of the overall nursing process and enhances the patient's user experience. After the negative pressure mechanism 2 is activated, negative pressure is generated inside the mouthpiece 1. When the suction tube 3 is inserted into the patient's throat, sputum is drawn into the suction tube 3 under the action of negative pressure. Since the collection bag 4 is directly connected to the suction tube 3 through the three-way tube 31, the sputum enters the three-way tube 31 along the suction tube 3 and then flows into the collection bag 4. During the whole process, the sputum will not come into contact with the internal space of the suction nozzle 1, thus achieving effective protection of the suction nozzle 1.

[0022] The straw 3 and the three-way tube 31 are integrally molded. This integral design enhances the strength and sealing of the connection between the straw 3 and the three-way tube 31. The strength ensures that the two will not separate due to suction or improper operation during sputum suction, guaranteeing smooth sputum suction. The sealing prevents sputum leakage from the connection during suction, avoiding environmental pollution and further improving the reliability and hygiene of the sputum suction device. The integral molding eliminates the gaps that may occur with traditional connection methods between the straw 3 and the three-way tube 31. During negative pressure suction, the internal pressure acts on the entire continuous tubing structure. Because there are no weak connection points, it can stably withstand the pressure, maintain good suction effect, and ensure that sputum flows smoothly from the straw 3 through the three-way tube 31 into the collection bag 4.

[0023] To facilitate replacement of the full collection bag 4 during use, a nut 311 is fixedly fitted onto the T-connector 31, with the nut 311 threaded onto the end of the collection bag 4. This threaded connection greatly facilitates the replacement of the full collection bag 4 by medical staff during patient expectoration. When the collection bag 4 is about to be full of sputum, the medical staff simply rotate the nut 311. Because the nut 311 is threaded onto the end of the collection bag 4, the two gradually separate during rotation, allowing the full collection bag 4 to be removed. Then, align the end of the new collection bag 4 with the T-connector 31, and rotate the nut 311 in the opposite direction to ensure a tight connection, completing the replacement process.

[0024] The negative pressure mechanism 2 includes a cylinder 21 connected to the suction nozzle 1, a piston 22 disposed within the cylinder 21, and a pull rod 23 inserted into the end of the cylinder 21 away from the suction nozzle 1 and fixedly connected to the piston 22. Medical personnel or nurses can flexibly control the pulling speed and force of the pull rod 23 according to actual conditions, thereby precisely adjusting the negative pressure inside the suction nozzle 1 to meet the sputum expectoration needs of different patients. Compared to some complex electric negative pressure devices, it is less expensive and can be used normally in places with inconvenient power supply, offering better applicability and versatility. When medical personnel pull the pull rod 23, the pull rod 23 drives the piston 22 to move away from the suction nozzle 1 within the cylinder 21. According to the relationship between gas volume and pressure, the movement of the piston 22 increases the space within the cylinder 21, causing the gas volume to expand and the pressure to decrease, thus creating negative pressure inside the suction nozzle 1. This negative pressure is transmitted to the suction tube 3 through a pipe connected to the suction nozzle 1, drawing sputum from the patient's throat into the suction tube 3 and draining it into the collection bag 4.

[0025] To prevent slippage between the hand and lever 23, a handle 231 is fixedly connected to the end of lever 23 furthest from piston 22. Handle 231 increases the contact area and friction between the medical staff's hand and lever 23, effectively preventing slippage during lever 23 operation. This allows medical staff to operate lever 23 more stably and precisely, ensuring that the negative pressure mechanism 2 can continuously and stably generate the required negative pressure, providing a reliable guarantee for successful sputum suction and improving the safety and accuracy of the operation. When pulling lever 23, the medical staff grips handle 231, which increases friction between the handle and the skin. Simultaneously, the larger contact area disperses the force applied by the hand, allowing for a more secure grip on handle 231, thus stably pulling lever 23 and moving piston 22 within cylinder 21, achieving stable control of the negative pressure inside suction nozzle 1.

[0026] To prevent gas from being expelled from the cylinder 21 into the patient's body when the piston 22 moves towards the suction nozzle 1, a first one-way valve 211 is fixedly installed on the cylinder 21 to allow gas from the suction nozzle 1 to flow into the cylinder 21. The first one-way valve 211 effectively prevents gas from being mistakenly expelled into the patient's body when the piston 22 moves towards the suction nozzle 1. This function ensures the patient's safety during sputum expectoration, avoiding problems such as choking, discomfort, or even respiratory damage that may be caused by abnormal airflow impacting the patient's airway, thus improving the safety and reliability of sputum expectoration nursing procedures. When the piston 22 moves towards the suction nozzle 1, the gas pressure inside the cylinder 21 increases. The design of the first one-way valve 211 ensures that, under the influence of the pressure difference, gas only flows into the cylinder 21 from the direction of the suction nozzle 1, preventing gas in the cylinder 21 from flowing back towards the suction nozzle 1 and entering the patient's body. Only when the piston 22 moves away from the nozzle 1 and the pressure inside the cylinder 21 decreases to form a negative pressure, will the first one-way valve 211 open, allowing the gas inside the nozzle 1 to flow into the cylinder 21 and maintain the normal working cycle of the negative pressure mechanism 2.

[0027] To facilitate the discharge of gas from inside cylinder 21, a second one-way valve 212 is fixedly installed on cylinder 21, communicating with the inside of cylinder 21 to discharge the gas. The second one-way valve 212 facilitates the discharge of gas from inside cylinder 21, ensuring the continuous and stable operation of the negative pressure mechanism 2. During the continuous reciprocating motion of piston 22, if the gas inside cylinder 21 cannot be discharged in time, it will lead to internal pressure imbalance, affecting the generation and maintenance of negative pressure. The presence of the second one-way valve 212 ensures smooth gas discharge, enabling the negative pressure mechanism 2 to operate efficiently and stably, improving the overall performance and working efficiency of the sputum suction device. When piston 22 moves closer to suction nozzle 1, the gas inside cylinder 21 is compressed, and the pressure increases. At this time, the second one-way valve 212 opens under the action of the pressure difference, and the gas inside cylinder 21 is discharged into the external environment through the second one-way valve 212. When piston 22 moves in the reverse direction to create negative pressure, the second one-way valve 212 closes to prevent outside air from flowing back into cylinder 21, ensuring that effective negative pressure can be formed and maintained in cylinder 21, and ensuring that the negative pressure mechanism 2 can continuously provide stable suction for sputum removal.
