Description

Technical Field

[0001] The present invention relates to the technical field of ventilator accessories, and in particular to a condensed water collecting device for a ventilator. Background Art

[0002] Ventilators are very common medical devices. When a patient is seriously ill and unable to breathe on their own, they are used to assist or force the patient to breathe. During operation, condensation forms in the ventilator's tubing. This accumulation of condensation can affect the stability of gas flow and pressure within the tubing and can also easily breed bacteria. Therefore, a condensation collection device is required to collect the condensation in the ventilator tubing.

[0003] Current condensate collection devices are manually installed on the ventilator tubing and must be positioned at the lowest point of the tubing to allow condensed water to flow automatically into the device under the influence of gravity. This condensate collection requires frequent manual emptying, which is quite cumbersome. Summary of the Invention

DETAILED DESCRIPTION

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0017] This embodiment provides a ventilator condensate collection device, referring to Figure 1 As shown, it includes a bracket 100, a diversion and collection mechanism 200, a rotating dumping assembly 300, and a water storage container 400. The diversion and collection mechanism 200 includes a cylinder 210 mounted on the bracket 100. The top of the cylinder 210 is provided with a water inlet interface 211 connected to the pipeline of the ventilator. The interior of the cylinder 210 is provided with a diversion cover 212 located below the water inlet interface 211. The bottom of the cylinder 210 is provided with a drainage channel 213.

[0018] The rotary tipping assembly 300 includes a drive motor 310, a rotating shaft 320, and at least two collection containers 330. The drive motor 310 is fixed to the barrel 210. One end of the rotating shaft 320 is drivingly connected to the output of the drive motor 310, and the other end extends into the barrel 210. Each collection container 330 is spaced circumferentially along the rotating shaft 320 and positioned within the barrel 210. Driven by the rotating shaft 320, each collection container 330 periodically alternates between a water receiving position and a water discharge position. When in the water receiving position, the collection container 330 opens upward and forms a sealed contact with the lower end of the deflector 212. When in the water discharge position, the collection container 330 opens downward and aligns with the drainage channel 213. The water storage container 400 is detachably mounted on the bracket 100, with the top opening of each water storage container 400 facing the drainage channel 213.

[0019] Based on the above-described overall structure, when the ventilator condensate collection device of this embodiment is in use, condensate in the ventilator pipeline flows into the barrel 210 through the water inlet port 211 at the top of the barrel 210, and then flows into the collection container 330 located in the water receiving station through the flow guide 212. After the collection containers 330 located in the water receiving station have collected a certain amount of condensate or for a certain period of time, the drive motor 310 can drive the rotating shaft to rotate, driving each collection container 330 to rotate, so that the positions of the collection containers 330 in the water receiving station and the drainage station are swapped, thereby completing the collection and dumping of the condensate.

[0020] In this embodiment, by providing the aforementioned multiple rotatable collection containers 330, compared to exposing the ventilator's tubing directly to the air, allowing condensed water to flow into the water storage container 400, this embodiment's solution reduces the risk of cross-infection among patients by maintaining a seal between the collection containers 330 at the water receiving station and the shroud 212. Furthermore, compared to the existing practice of attaching a cup to the tubing to collect condensed water, this embodiment eliminates the need for manual emptying of the cup, making it more convenient to use. In other words, the water storage container 400 of this embodiment significantly reduces the frequency of water refilling.

[0021] The bracket 100 is used to be placed on the ground, and its specific structure can be set as needed, which will not be described in detail here.

[0022] In this embodiment, reference Figure 3 As shown, a plurality of first pull rings 214 are provided on the top of the cylinder 210, and a plurality of second pull rings 110 are correspondingly provided on the bracket 100. One end of each connecting rope is connected to each first pull ring 214, and the other end is connected to the corresponding second pull ring 110. The number of the first pull rings 214 and the second pull rings 110 is, for example, four or other numbers.

[0023] That is, in this embodiment, the cylinder 210 is connected to the bracket 100 through multiple connecting ropes, so that when the eccentric block 323 described below rotates, the cylinder 210 can have a certain swing relative to the bracket 100, thereby causing the pipeline connected to the cylinder 210 to swing slightly, so as to facilitate the condensed water in the pipeline to flow into the cylinder 210.

[0024] refer to Figure 4 As shown, in this embodiment, a one-way bearing 321 is fixedly mounted on the rotating shaft 320. A fixing ring 322 is fixedly mounted on the one-way bearing 321. Each collection container 330 is fixedly connected to the fixing ring 322. An eccentric mass 323 is also fixedly mounted on the rotating shaft 320. In this embodiment, the one-way bearing 321 ensures that when the drive motor 310 rotates the rotating shaft 320 in one direction, it simultaneously rotates the eccentric mass 323 and the fixing ring 322. The rotation of the fixing ring 322 also rotates the collection containers 330. However, when the rotating shaft 320 rotates in the other direction, only the eccentric mass 323 rotates, without rotating the collection containers 330.

[0025] Based on the above structure, in this embodiment, when the collecting container 330 needs to be rotated, the driving motor 310 can drive the rotating shaft 320 to rotate in the corresponding direction; and when the collecting container 330 does not need to be rotated, the driving motor 310 can drive the rotating shaft 320 to rotate in the opposite direction to drive the eccentric block 323 to rotate, thereby causing the cylinder 210 to shake, so as to accelerate the flow of condensed water in the pipeline into the collecting container 330.

[0026] In this embodiment, friction pads are provided on each sidewall of the groove. When each collection container 330 rotates to the water receiving position, the two opposite sides of the collection container 330 contact the friction pads on the two sidewalls of the groove. In other words, in this embodiment, when the collection container 330 rotates to the water receiving position, the friction pads on the two sidewalls of the groove exert a friction force on the collection container 330.

[0027] By providing the two friction pads, after the rotating shaft 320 rotates the collection container 330 to the water collection station, the frictional force exerted by the friction pads on the collection container 330 can maintain the collection container 330 in its current position when the rotating shaft 320 rotates in the opposite direction to drive the eccentric weight 323, preventing the collection container 330 from moving unexpectedly. When the collection container 330 needs to rotate, the torque exerted by the rotating shaft 320 on the collection container 330 can overcome the frictional force exerted by the friction pads, allowing the collection container 330 to rotate as intended. It should be noted that the friction pads are not shown in the drawings of this embodiment to avoid comprehending the details.

[0028] refer to Figure 4As shown, in this embodiment, the deflector 212 in the cylinder 210 includes a conical section and a circular section connected in series, and the circular section is located below the conical section; and along the direction from top to bottom, the diameter of the conical section gradually decreases, and an arc-shaped groove is constructed on the bottom end surface of the circular section. When the collection container 330 is at the water receiving station, the collection container 330 is inserted into the groove.

[0029] By configuring the deflector 212 to include a conical section and a circular section, it is convenient for water to flow into the deflector 212 through the water inlet interface 211 and fall into the collection container 330 , and by configuring an arc-shaped groove, it is convenient for the collection container 330 to rotate to dock with the deflector 212 .

[0030] In this embodiment, a liquid level sensor is installed within the water storage container 400. An alarm indicator light, electrically connected to the liquid level sensor, is embedded in the sidewall of the bracket 100. When the liquid level within the water storage container 400 reaches a preset height, an audible and visual alarm is triggered. This serves to alert personnel to replace the liquid within the water storage container 400. It should be noted that the liquid level sensor and audible and visual alarm can be existing products. Furthermore, the liquid level detection by the liquid level sensor and the audible and visual alarm triggering of an alarm when the liquid level sensor reaches a preset height can be described in detail in the prior art and will not be further described here.

[0031] In this embodiment, reference Figure 5 As shown, ventilation holes are provided on the side wall of the barrel 210, and a drying mechanism 500 is fixed to the side wall of the barrel 210. The drying mechanism 500 includes a housing 510 fixed to the outside of the barrel 210. A heating wire 520 and a fan 530 are provided in the housing 510. The heating wire 520 is used to heat air, and the fan 530 is used to blow the heated air into the barrel 210 through the ventilation holes. By providing the above-mentioned drying mechanism 500 and blowing hot air into the barrel 210, the inside of the barrel 210 can be kept dry, and the growth of bacteria in the barrel 210 can be prevented, thereby reducing the risk of cross infection.

[0032] In this embodiment, the water storage container 400 is slidably disposed on the frame and can be pulled out from the frame to facilitate pouring out the water collected in the water storage container 400 .

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
