Abstract
Description
Technical Field
[0001] This application relates to the technical field of suction devices, and in particular to a multifunctional composite sputum scraping structure for a suction tube connector. Background Technology
[0002] Suction catheters are primarily used to remove sputum or large amounts of secretions from the trachea, effectively cleaning the airway and preventing symptoms such as respiratory limitation or even respiratory failure. They are commonly used for routine suctioning and tracheotomy of wounded or sick personnel, and are suitable for military combat medical care as well as for timely suctioning of airway mucus or vomit in hospitals or homes.
[0003] However, the existing suction catheter connectors lack a multi-functional composite sputum scraping structure. When the suction catheter is returned to the protective sleeve after suctioning, a large amount of sputum is easily left at the connection between the connector and the multi-port tube. This makes it difficult to clean the sputum, leading to cross-infection, and may even cause blockage at the connection between the connector and the multi-port tube, posing a certain threat to the patient's life. Therefore, there is a real need to improve the existing connectors used for suction catheters. Utility Model Content
[0004] To address the aforementioned deficiencies, this application provides a multifunctional composite sputum scraping structure for a suction tube connector.
[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions:
[0006] A multifunctional composite sputum scraping structure for a suction tube connector includes a suction tube connector, the suction tube connector includes a cleaning chamber, and suction tube connectors and catheter connectors located at both ends of the cleaning chamber, which are used to connect a multi-port tube and a negative pressure assembly, respectively. The negative pressure assembly includes a catheter and a negative pressure control end.
[0007] A barrier ring is provided at the connection between the cleaning chamber and the catheter connection end. A barrier valve is provided at the connection between the cleaning chamber and the suction connection end. A scraping part is provided on the inner wall surface of the barrier valve. The scraping part includes several protrusions. The catheter passes through the suction connection seat from the catheter connection end and passes through the suction connection end into the multi-port tube.
[0008] The blocking ring and the sputum scraping part are both used to scrape off the sputum adhering to the outer wall of the catheter and retain it in the cleaning chamber.
[0009] The protrusion is designed to increase in size towards the center of the barrier valve.
[0010] By adopting the above technical solution, the suction connection seat includes a cleaning chamber, and suction connection ends and catheter connection ends disposed at both ends of the cleaning chamber. The suction connection end is used to connect a multi-port tube, which is used to connect to the patient end and equipment such as a ventilator. The catheter connection end is used to connect a catheter and a negative pressure assembly. The negative pressure assembly includes a catheter and a negative pressure control end, used to suction sputum from the patient's trachea through negative pressure. A barrier ring is provided at the connection between the cleaning chamber and the catheter connection end, and a barrier valve is provided at the connection between the cleaning chamber and the suction connection end. A scraping part is fixedly provided on the inner wall surface of the barrier valve. The scraping part includes several protrusions, and the protrusions are arranged to increase in size towards the center of the barrier valve. The catheter enters the cleaning chamber from the catheter connection end and then enters the multi-port tube through the suction connection end to the patient end for suction. When the catheter is returned to its original position after suction, the scraping parts on the barrier ring and the barrier valve are used to scrape the sputum adhering to the outer wall of the catheter into the cleaning chamber. This design facilitates sputum removal. Furthermore, the protrusions on the inner wall of the barrier valve gradually increase in size towards the center of the valve, ensuring that all or most of the protrusions tightly abut against the outer wall of the catheter when it passes through. This not only enhances the scraping effect on the catheter surface but also improves the sealing performance of the barrier valve and adapts to catheters of various diameters. By incorporating a barrier valve, this application improves the airtightness and sealing of the cleaning chamber. The barrier rings at both ends of the cleaning chamber and the scraping part on the surface of the barrier valve scrape away and retain the sputum adhering to the outer wall of the catheter within the cleaning chamber, thus facilitating sputum removal. Simultaneously, the protrusions on the inner wall of the barrier valve gradually increase in size towards the center of the valve, ensuring that all or most of the protrusions tightly abut against the outer wall of the catheter when it passes through. This not only enhances the scraping effect on the catheter surface and reduces patient safety risks but also improves the sealing performance of the barrier valve and adapts to catheters of various diameters.
[0011] Optionally, the barrier ring is fixedly disposed at the connection between the cleaning chamber and the conduit connection end, and the barrier ring is fixedly disposed on the inner wall of the cleaning chamber;

Thus, during the return process of the catheter, the through hole wall of the blocking ring blocks the sputum adhering to the outer wall of the catheter in the cleaning chamber, thereby making it easier to clean the sputum.
[0014] Optionally, the barrier valve includes an mounting ring and several valve plates. The mounting ring is installed at the connection between the cleaning chamber and the suction connection end, and the mounting ring is sleeved on the outer wall of the cleaning chamber.

Several valve plates are integrally formed on the surface of the installation ring, and the several valve plates cover and seal the port of the cleaning chamber. The setting of the barrier valve improves the airtightness and sealing of the connection between the cleaning chamber and the suction connection end.
[0017] Optionally, three or more valve plates may be provided.
[0018] By adopting the above technical solution, three or more valve plates are set, so that the valve plates can be opened smoothly when the conduit passes through, making it easy to open and close for conduction, and automatically close after the conduit returns to its original position, thereby maintaining the airtightness and sealing of the connection seat.

[0023] Optionally, a cleaning connector may be detachably connected to the end of the tube away from the cleaning chamber, and a capping assembly may be detachably connected to the end of the cleaning connector away from the tube.
[0024] By adopting the above technical solution, a cleaning connector is detachably connected to the end of the tube away from the cleaning chamber, and a capping assembly is detachably connected to the end of the cleaning connector away from the tube.

[0039] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-3 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.
[0040] This application discloses a multifunctional composite sputum scraping structure for a suction tube connector, such as... Figures 1-3 As shown, the device includes a suction connection seat 1, which includes a cleaning chamber 2, and suction connection ends 3 and catheter connection ends 4 located at both ends of the cleaning chamber 2. The suction connection ends 3 are used to connect to a multi-port tube 8, which is used to connect to the patient end and equipment such as a ventilator. The catheter connection ends 4 are used to connect to a catheter and a negative pressure assembly, which includes a catheter 5 and a negative pressure control end (not shown in the figure), used to suction sputum from the patient's trachea through negative pressure.
[0041] In this embodiment, specifically, the suction connector 1 has an integrally formed sidewall with a tube 8 communicating with the inner cavity of the cleaning chamber 2, used to introduce medication to clean the sputum in the cleaning chamber 2. A cleaning connector 9 is detachably connected to the end of the tube 8 away from the cleaning chamber 2, and a sealing assembly 10 is detachably connected to the end of the cleaning connector 9 away from the tube 8. The sealing assembly 10 controls the opening and closing of the cleaning connector 9, thereby facilitating the introduction of medication. The sealing assembly 10 includes a cleaning tube 1010, a fixing connector 1020, and a sealing cap. The cover 1030 and the cleaning tube 1010 are inserted into the cleaning connector 9 and connected to the through tube 8. The fixed connector 1020 is fixedly sleeved on the end of the cleaning tube 1010 away from the through tube 8. The cover 1030 is fixedly set on the end of the fixed connector 1020 away from the cleaning tube 1010. By opening the cover 1030 and introducing medicine into the fixed connector 1020, the medicine enters the cleaning chamber 2 through the cleaning tube 1010 and the through tube 8, thereby cleaning the sputum retained in the cleaning chamber 2.
[0042] In this embodiment, the sealable cover 1030 is integrally formed with a lifting part 1031. The surface of the lifting part 1031 is provided with a plurality of anti-slip textures 1032 to improve the friction of the lifting part 1031 and make it easier for the user to open the sealable cover 1030 through the lifting part 1031.
[0043] In this embodiment, specifically, a blocking ring is provided at the connection between the cleaning chamber 2 and the catheter connection end 4, and a blocking valve 7 is provided at the connection between the cleaning chamber 2 and the suction connection end 3. A scraping part 721 is fixedly provided on the inner wall surface of the blocking valve 7. The scraping part 721 includes several protrusions 7211, which are arranged to increase in size towards the center of the blocking valve 7. The catheter 5 passes through the catheter connection end 4 into the cleaning chamber 2 and through the suction connection end 3 into the multi-port tube 8. During the process, the blocking ring and the blocking valve 7... The scraping section 721 on the tube 5 is used to scrape the sputum adhering to the outer wall of the tube 5 into the cleaning chamber 2, so that the sputum is easy to clean. At the same time, the protrusions 7211 provided on the inner wall of the barrier valve 7 gradually increase in size towards the center of the barrier valve 7, so as to ensure that all or most of the protrusions 7211 can tightly abut against the outer wall of the tube 5 when the tube 5 passes through. This not only enhances the effect of scraping the sputum on the surface of the tube 5, but also enhances the sealing of the barrier valve 7, and is adaptable to various tubes 5 with different diameters.
[0044] A blocking ring is fixedly installed at the connection between the cleaning chamber 2 and the catheter connection end 4, and is also fixedly installed on the inner wall of the cleaning chamber 2. A through hole 610 is formed on the surface of the blocking ring, and the inner diameter of the through hole 610 is adapted to the interface diameter of the catheter 5. This allows the through hole 610 of the blocking ring to block sputum adhering to the outer wall of the catheter 5 within the cleaning chamber 2 during the return process of the catheter 5, thus facilitating sputum cleaning. The blocking valve 7 includes an mounting ring 710 and several valve plates 720. The mounting ring 710 is installed at the connection between the cleaning chamber 2 and the suction connection end 3, and is sleeved on the outer wall of the cleaning chamber 2. The several valve plates 720 are integrally formed and installed on the mounting ring 710. The surface of the ring 710 and several valve plates 720 cover and seal the port of the cleaning chamber 2. The setting of the barrier valve 7 improves the airtightness and sealing of the cleaning chamber 2 and the suction connection end 3. The valve plates 720 are set in three or more depending on the situation. In this embodiment, eight are shown in the figure, so that the valve plates 720 can be opened smoothly when the tube 5 passes through, making it easy to open and close for conduction, and automatically close after the tube 5 returns, thereby maintaining the airtightness and sealing of the connection seat. The inner wall of the valve plates 720 is provided with a scraping part 721. By providing a scraping part 721 on the inner wall of the valve plate 720, the outer wall of the tube 5 can be scraped from multiple directions when the tube 5 returns.
[0045] The implementation principle of the multifunctional composite sputum scraping structure of the suction tube connector in this application embodiment is as follows:
[0046] The catheter is inserted into the cleaning chamber from the catheter connection end and then through the suction connection end into the multi-port tube to suction sputum from the patient. After suctioning, when the catheter is returned to its original position, the sputum scraping ring and the scraping part on the barrier valve are used to scrape away the sputum adhering to the outer wall of the catheter into the cleaning chamber. After the catheter is returned to its original position, the valve plate on the barrier valve resets to close the interior of the cleaning chamber. At this time, by opening the sealable cap and introducing medication into the fixed connector, the medication enters the cleaning chamber through the cleaning tube and the through-tube, thereby cleaning the sputum remaining in the cleaning chamber. This application improves the cleaning efficiency by incorporating a barrier valve. The airtight and sealed design of the washing chamber, along with the blocking rings at both ends and the scraping section on the surface of the blocking valve, removes sputum adhering to the outer wall of the catheter and retains it within the washing chamber, making it easier to clean. Meanwhile, the protrusions on the inner wall of the blocking valve gradually increase in size towards the center of the valve to ensure that all or most of the protrusions can tightly abut against the outer wall of the catheter when it passes through. This not only enhances the effect of scraping sputum from the catheter surface and reduces patient safety risks, but also enhances the sealing performance of the blocking valve and adapts to catheters of various sizes and diameters.
[0047] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
