Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a ventilator condensate collection device. Background Technology

[0002] In modern medicine, ventilators, as vital life support equipment, are widely used in various medical institutions to provide essential oxygen supply and respiratory support for patients requiring respiratory assistance. However, a common problem during ventilator use is the generation and accumulation of condensate.

[0003] When a ventilator is working, it typically humidifies and warms the inhaled air using a heated humidifier to simulate the normal breathing environment. However, as the humidified air passes through the ventilator's tubing and condensate line, the water vapor in the air condenses into liquid water due to the drop in ambient temperature, accumulating in the tubing. If this condensate is not drained promptly, it can not only affect the normal operation of the ventilator but also become a breeding ground for bacteria, posing a potential threat to the patient's health. To address this issue, existing ventilators are usually equipped with condensate collection devices. For example, Chinese Patent Publication No. CN118811315A discloses a one-way medical condensate collection bucket, which relates to the field of collection bucket technology. It includes a bucket body, a fixed cover fixed at one end of the top of the bucket body, an opening and closing cover movably connected to the fixed cover at the top of the bucket body, a partition fixed inside the bucket body, a fixed cylinder fixed at the middle position inside the partition, a drain cylinder elastically connected inside the fixed cylinder, a first spring fixed between the fixed cylinder and the drain cylinder, and a drain hole opened inside the drain cylinder. A lifting rod elastically connected inside the bucket body, and a lifting frame fixed at one end of the lifting rod in contact with the bottom of the opening and closing cover.

[0004] Currently, there are some other improved condensate collection devices, but they are often too complex and inconvenient to clean and maintain. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a ventilator condensate collection device, which solves the technical problems that the existing ventilator condensate collection devices are too complicated and inconvenient to clean and maintain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ventilator condensate collection device, which is connected to the condensate pipe of the ventilator.

[0007] Includes a one-way valve connected to the condensate pipe and a collection cylinder connected to the one-way valve;

[0008] The upper end of the collecting cylinder is provided with an inlet for connecting a one-way valve, and the lower end of the collecting cylinder is provided with an outlet for discharging liquid.

[0009] The collecting cylinder is provided with a spherical cover covering the liquid inlet, and a spherical liquid outlet is opened at the lower end of the spherical cover.

[0010] The lower end of the collecting cylinder is provided with a stabilizing part, a connecting rod is inserted through the middle of the stabilizing part, a handle is provided on the end of the connecting rod outside the stabilizing part, the connecting rod is inserted into the collecting cylinder and the spherical liquid inlet and extends into the spherical cover body, and a sealed sphere is provided at one end of the connecting rod located in the spherical cover body.

[0011] Pulling the handle moves the connecting rod up and down, thus sealing or opening the sealed sphere and the liquid outlet on the sphere.

[0012] Furthermore, a liquid level sensor is installed outside the collection cylinder for sensing the liquid level.

[0013] Furthermore, a buzzer is installed outside the collection tube for reminders and alarms.

[0014] Furthermore, the one-way valve includes a valve body, with an inlet valve port at the upper end and an outlet valve port at the lower end. A liquid channel is formed between the inlet and outlet valve ports. A contraction port is formed on the liquid channel near the inlet valve port, and an expansion port is formed at the lower end of the contraction port. A guide port is formed at the lower end of the expansion port. A sliding sleeve is provided on the liquid channel, and a liquid passage is provided on the side of the sliding sleeve at the expansion port. A clamping spring is provided on the inner side of the sliding sleeve. A pressure ring is threadedly connected to the lower end of the device and located at the lower end of the tightening spring. The pressure ring has a polygonal opening in the middle, which is connected to the inlet of the liquid cylinder. The pressure ring, through the pressure tightening spring, tightens the sliding sleeve at the contraction port, thereby achieving a seal. When liquid enters through the inlet valve, the pressure on the sliding sleeve opens the contraction port, allowing the liquid to flow. When liquid enters through the outlet, the pressure on the sliding sleeve tightens the sliding sleeve at the contraction port, thereby closing the liquid channel.

[0015] Furthermore, a locking boss is provided at the upper end of the liquid inlet of the collecting cylinder, and the liquid outlet of the valve body is threadedly connected to the locking boss.

[0016] Furthermore, the valve body is provided with a valve sealing ring that seals with the locking boss.

[0017] Furthermore, the connecting rod and the sealed sphere are connected by a spring.

[0018] Furthermore, a screw section is provided on the part of the connecting rod near the handle, and a threaded section is provided on the stabilizing part. The connecting rod achieves a threaded connection by cooperating with the threaded section on the stabilizing part through the screw section.

[0019] Furthermore, an arc-shaped protrusion is provided on the bottom inner side of the collection cylinder to direct the liquid flow, and a rod sealing ring is provided inside the arc-shaped protrusion to seal with the connecting rod.

[0020] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0021] 1. This design, through the connection structure of the one-way valve and the collection cylinder, ensures that condensate can only flow into the collection cylinder in one direction, effectively preventing backflow and splashing. Simultaneously, by pulling the handle to control the sealing or opening of the sealed sphere and the liquid inlet on the spherical surface, the drainage operation is simplified, improving the practicality and operability of the device. The design of the spherical cover also allows condensate to flow smoothly into the collection cylinder. Furthermore, the sealed sphere can also seal with the liquid inlet, thus preventing condensate from entering. The stabilizing part can be made of rubber, which can both seal with the connecting rod and dampen the connecting rod, allowing the connecting rod to stop at any position. The collection cylinder can be made of transparent material for easy observation.

[0022] 2. The liquid level sensor enables the device to monitor the liquid level in the collection tank in real time, providing medical staff with accurate liquid level information. This facilitates timely assessment and handling of condensate accumulation issues, improving the device's safety. The buzzer, working in conjunction with the liquid level sensor, sounds an alarm when the liquid level reaches a preset value, reminding medical staff to drain the liquid promptly. This effectively prevents condensate overflow or excessive accumulation, further enhancing the device's safety and reliability. Additionally, a controller connecting the liquid level sensor and buzzer can be installed for power supply and control. The controller can be positioned anywhere on the outer wall of the collection tank.

[0023] 3. The one-way valve enables unidirectional liquid flow. The cooperation of the sliding sleeve, tightening spring, and pressure ring allows the one-way valve to automatically open when liquid flows in and tightly close when liquid attempts to flow out, effectively preventing the backflow of condensate. This design improves the sealing performance and reliability of the device, ensuring effective collection of condensate. The threaded connection between the locking boss and the valve body outlet makes the connection between the one-way valve and the collection cylinder more secure and reliable, effectively preventing loosening and leakage at the connection point. It also simplifies installation and disassembly. The valve sealing ring further improves the sealing performance between the one-way valve and the collection cylinder, effectively preventing condensate leakage.

[0024] 4. The spring mechanism allows the sealed sphere to move more flexibly under the influence of the connecting rod, improving the sealing and opening effect between the sealed sphere and the liquid outlet on the spherical surface. Furthermore, the elastic tension further enhances the sealing effect. The spring mechanism also acts as a shock absorber, reducing the shaking of the collection cylinder and effectively achieving stability.

[0025] 5. The screw section and threaded section can be used to achieve a seal between the sealed ball and the liquid inlet or liquid inlet cylinder by rotation, making the operation more stable and convenient.

[0026] 6. The arc-shaped protrusion allows liquid to flow to the periphery, thus facilitating the discharge of condensate from the outlet. The rod-body sealing ring also ensures a more effective seal. Attached Figure Description

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0034] refer to Figures 1 to 3 This embodiment provides a ventilator condensate collection device, which is connected to the condensate pipe 1 of the ventilator.

[0035] Includes a one-way valve 3 connected to the condensate pipe 1 and a collection cylinder 2 connected to the one-way valve 3;

[0036] The upper end of the collecting cylinder 2 is provided with an inlet 21 connected to a one-way valve 3, and the lower end of the collecting cylinder 2 is provided with an outlet 22, on which a drain valve 6 is provided.

[0037] The collection cylinder 2 is provided with a spherical cover 27 covering the liquid inlet 21, and a spherical liquid outlet 271 is provided on the lower end of the spherical cover 27.

[0038] The lower end of the collecting cylinder 2 is provided with a stabilizing part 23. A connecting rod 24 is passed through the middle of the stabilizing part 23. A handle 25 is provided on the end of the connecting rod 24 located outside the stabilizing part 23. The connecting rod 24 passes through the collecting cylinder 2 and the spherical liquid outlet 271 and extends into the spherical cover 27. A sealed sphere 26 is provided at one end of the connecting rod 24 located in the spherical cover 27.

[0039] When the handle 25 is pulled, the connecting rod 24 moves up and down, thereby sealing or opening the sealed ball 26 and the spherical liquid outlet 271.

[0040] A liquid level sensor 4 is installed on the outside of the collection cylinder 2 for sensing the liquid level. A buzzer 5 is installed on the outside of the collection cylinder 2 for alerting and alarming. The liquid level sensor 4 and the buzzer 5 are both conventional components. The liquid level sensor 4 and the buzzer 5 can be used in combination, or a controller can be set up for power supply and control. The controller can be set on the outer wall of the collection cylinder 2. These are all conventional technologies.

[0041] The one-way valve 3 includes a valve body 31. An inlet valve port 311 is located at the upper end of the valve body 31, and an outlet valve port 312 is located at the lower end of the valve body 31. A liquid channel is formed between the inlet valve port 311 and the outlet valve port 312. A contraction port 313 is formed on the liquid channel near the inlet valve port 311. An expansion port 314 is located at the lower end of the contraction port 313, and a guide port 315 is located at the lower end of the expansion port 314. A sliding sleeve 32 is provided on the liquid channel. A liquid passage port 321 is located on the side of the sliding sleeve 32 at the expansion port 314. A tensioning spring 33 is provided on the inner side of the sliding sleeve 32. A pressing screw ring 34 is threadedly connected to the lower end of the body channel and located at the lower end of the pressing spring 33. The pressing screw ring 34 has a polygonal opening 341 in the middle, which is connected to the liquid inlet 21. The pressing screw ring 34 presses against the pressing spring 33, thereby pressing the sliding sleeve 32 against the contraction port 313 to achieve a seal. When liquid enters from the liquid inlet 311, the pressing of the sliding sleeve 32 opens the connection between the sliding sleeve 32 and the contraction port 313, thus allowing the liquid to flow. When liquid enters from the liquid outlet, the pressing of the sliding sleeve 32 presses it against the contraction port 313, thus closing the liquid channel. A locking boss 211 is provided at the upper end of the liquid inlet 21 of the collecting cylinder 2, and the liquid outlet of the valve body 31 is threadedly connected to the locking boss 211. The valve body 31 is provided with a valve sealing ring 316 that seals with the locking boss 211.

[0042] The one-way valve 3 enables unidirectional liquid flow. The cooperation of the sliding sleeve 32, the clamping spring 33, and the pressure ring 34 allows the one-way valve 3 to automatically open when liquid flows in and tightly close when liquid attempts to flow out, effectively preventing the backflow of condensate. This design improves the sealing performance and reliability of the device, ensuring effective collection of condensate. The threaded connection between the locking boss 211 and the outlet of the valve body 31 makes the connection between the one-way valve 3 and the collection cylinder 2 more secure and reliable, effectively preventing loosening and leakage at the connection point. It also simplifies installation and disassembly. The valve sealing ring 316 further improves the sealing performance between the one-way valve 3 and the collection cylinder 2, effectively preventing condensate leakage.

[0043] The aforementioned collecting cylinder 2 is preferably a transparent plastic cylinder, and the aforementioned stabilizing part 23 is preferably a flexible material with high friction, such as rubber. The aforementioned connecting rod 24 and sealing ball 26 are not strictly limited in terms of material; they can be made of rigid plastic or metal.

[0044] The working method of this solution is as follows:

[0045] Connect the inlet valve 311 of the one-way valve 3 to the condensate tube 1 of the ventilator, ensuring a tight, leak-free connection. Connect the outlet valve 312 of the one-way valve 3 to the inlet 21 of the collection tube 2 via the locking boss 211 and the valve sealing ring 316, and tighten until sealed. Ensure the drain valve 6 is closed to prevent condensate from flowing out before operation. When it is necessary to drain the condensate from the condensate tube 1, pull the handle 25 to open the sealed ball 26, the spherical liquid outlet 271, and the inlet 21, allowing condensate to enter the collection tube 2 from the condensate tube 1. Turn on the level sensor 4 and the buzzer 5. The level sensor 4 monitors the liquid level in the collection tube 2 in real time. When the liquid level reaches the preset value, the buzzer 5 sounds an alarm to remind medical staff to drain the fluid in time.

[0046] When drainage is required, open the drain valve 6 and drain using the pipe connected to the drain valve 6. During drainage, pull the handle 25 to seal the sealed ball 26 and the inlet 21, thereby temporarily preventing condensate from entering. After operation, return to the initial state.

[0047] See again Figure 4 This second embodiment provides a ventilator condensate collection device based on the same inventive concept, which differs from the first embodiment in that:

[0048] The connecting rod 24 and the sealed sphere 26 are connected by a spring 242. The spring 242 allows the sealed sphere 26 to move more flexibly under the influence of the connecting rod 24, improving the sealing and opening effect between the sealed sphere 26 and the spherical liquid outlet 271. Furthermore, the elastic tension further enhances the sealing effect. The spring 242 also acts as a shock absorber, reducing the shaking of the collecting cylinder 2 and effectively achieving stability.

[0049] The connecting rod 24 is provided with a screw section 241 near the handle 25, and the stabilizing part 23 is provided with a threaded section 231. The connecting rod 24 is threadedly connected to the stabilizing part 23 by the engagement of the screw section 241 and the threaded section 231. The screw section 241 and the threaded section 231 allow for the sealing of the sealed sphere 26 with the spherical liquid port 271 or the liquid inlet 21 by rotation, making the operation more stable and convenient.

[0050] The bottom inner side of the collecting cylinder 2 is provided with an arc-shaped protrusion 28 for guiding the liquid flow. A rod sealing ring 281, which seals with the connecting rod 24, is provided inside the arc-shaped protrusion 28. The arc-shaped protrusion 28 allows the liquid to flow peripherally, thus facilitating the discharge of condensate from the outlet cylinder 22. The rod sealing ring 281 also provides a more effective seal.

[0051] The stabilizing part 23 and the arc-shaped protrusion 28 can also be integrally molded and made of a flexible material, such as rubber, thus penetrating the bottom of the collecting cylinder 2 and being fixedly connected to or detachably and sealed to the collecting cylinder 2. The fixed connection can be achieved through heat fusion. For a sealed connection, a threaded connection can be used; since it is made of rubber, an interference fit can be used to form a good seal. Of course, other rigid materials, such as plastic, can also be used; in this case, heat fusion is the better choice for fixation.

[0052] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
