Description

Technical Field

[0001] This utility model mainly relates to the technical field of medical devices, specifically a ventilator condensate collection device that can be suctioned by negative pressure. Background Technology

[0002] In intensive care unit (ICU) clinical practice, ventilators are crucial medical devices that prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. Ventilators are currently widely used in hospital emergency care and treatment. For patients requiring long-term ventilator use, humidification and heating are necessary to humidify the airway. However, this humidification process also generates significant condensation in the ventilator tubing. Backflow of this condensate is a major cause of ventilator-associated pneumonia (VAP). Furthermore, if this condensate is not collected and emptied promptly, it can narrow the tubing's inner diameter, increasing airway resistance and potentially causing suffocation.

[0003] Traditional ventilator condensate collection containers require manual emptying after being filled with condensate. This manual emptying necessitates frequent disconnection of the ventilator tubing, affecting treatment continuity, resulting in low collection efficiency, increased risk of tubing contamination due to excessive exposure, and the potential for condensate stagnation leading to bacterial growth. Therefore, a new ventilator condensate collection and emptying device is needed to address these technical problems. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model mainly provides a ventilator condensate collection device that can be suctioned under negative pressure to solve the technical problems mentioned in the background.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A ventilator condensate collection device with negative pressure suction includes a three-way tubing, a collection bottle, and a negative pressure suction device. The collection bottle has rotating disks at its upper and lower ends, and a partition plate connects the upper and lower rotating disks. The partition plate divides the space between the upper and lower rotating disks into two parts, and semi-circular limiting plates are connected to the upper and lower ends of both sides of the partition plate. Each of the semicircular limiting plates is provided with a number of evenly distributed drainage holes, and each of the rotating disks is provided with a number of evenly distributed docking holes on one half of its surface, and the upper and lower rotating disks have different sides of the docking holes. The partition plate is equipped with a drive assembly that drives the rotating disk to rotate.

[0006] Preferably, the three-way tubing has two ends configured as an air inlet port and an air outlet port, wherein the air inlet port is equipped with a one-way valve, and the three-way tubing is connected to the ventilator's breathing tubing through the air inlet port and the air outlet port.

[0007] Preferably, a negative pressure tube is connected between the negative pressure aspirator and the lower end of the collection bottle.

[0008] Preferably, a plurality of evenly distributed drainage holes correspond to a plurality of evenly distributed docking holes.

[0009] Preferably, the drive assembly includes fixed sleeves disposed on both sides of the partition plate, piston plates sliding inside the fixed sleeves, racks connecting the two piston plates, a gear ring meshing on one side of the racks, a rotating shaft rotatably disposed at the center inside the partition plate, the gear ring being sleeved on the rotating shaft, and the upper and lower ends of the rotating shaft being connected to upper and lower rotating disks respectively.

[0010] Preferably, the partition plate has a cavity inside to accommodate the gear ring, and the rack passes through the partition plate and its internal cavity.

[0011] Preferably, a vertical rod is connected between the upper and lower semicircular limiting plates, a float block is slidably installed on the vertical rod, and a hemispherical block is connected to the side of the piston plate away from the rack.

[0012] Preferably, the outer surface of the collection bottle is provided with a scale.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) When the three-way pipe discharges condensate into the collection bottle, the condensate falls into one half of the space of the collection bottle. As the condensate in this half increases, the top block of the float plate will also move upward until the top block of the float plate contacts the hemisphere block and pushes the hemisphere block into the fixed sleeve, thereby causing the rack to move. The movement of the rack will drive the rotating disk to rotate, thereby causing the rotating disk to rotate half a turn, so that the half space originally used for storing and transporting condensate will begin to discharge condensate. The condensate in the other side plate space has been drained and is used to collect condensate again. In summary: the collection bottle can be automatically collected, eliminating the need for manual emptying and repeated sterilization, reducing workload, saving time, and improving efficiency; furthermore, since the condensate bottle does not need to be disconnected for emptying, the ventilator tubing remains in a closed state, eliminating the need for repeated reconnection, reducing discomfort caused by ventilator tubing disconnection, and alleviating patient suffering; it also provides an additional layer of safety for critically ill patients and those who cannot be weaned off the ventilator.

[0014] (2) A one-way valve is used, which allows liquid to enter but not exit, effectively preventing patients from choking; a negative pressure aspirator is used, with a negative pressure tube connected between the negative pressure aspirator and the lower end of the collection bottle. By using a negative pressure aspirator, the condensate is thoroughly removed, avoiding condensate residue. It also requires manual pouring, which is convenient for use.

[0018] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intermediate element present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intermediate element present. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Example 1: Please refer carefully to the attached diagram. Figure 1 A ventilator condensate collection device with negative pressure suction includes a three-way tubing 10, a collection bottle 20, and a negative pressure suction device 30. The three-way tubing 10 has an inlet port and an outlet port at both ends. A one-way valve 101 is installed on the inlet port. The three-way tubing 10 connects to the ventilator's breathing circuit through the inlet and outlet ports. The one-way valve 101 ensures that liquid only enters and does not exit, effectively preventing the patient from coughing. A negative pressure tube 301 connects the negative pressure suction device 30 to the lower end of the collection bottle 20. By using the negative pressure suction device 30, condensate is thoroughly removed, avoiding condensate residue. It also requires manual emptying for ease of use.

[0022] Example 2: Please refer carefully to the attached diagram. Figures 1-4 Inside the collection bottle 20, rotating disks 201 are respectively rotatably arranged at the upper and lower ends. A partition plate 202 is connected between the two rotating disks 201, dividing the space between the two rotating disks 201 into two parts. Semicircular limiting plates 203 are respectively connected to the upper and lower ends of the two sides of the partition plate 202. Each semicircular limiting plate 203 is provided with several evenly distributed drainage holes 211. Each rotating disk 201 is provided with several evenly distributed docking holes 212 on one half of its surface, and the upper and lower rotating disks 201 have different sides of the docking holes 212. The several evenly distributed drainage holes 211 correspond to the several evenly distributed docking holes 212.

[0023] The mating hole 212 on the upper rotating disk 201 is aligned with the drainage hole 211 on one of the semicircular limiting plates 203, covering the drainage hole 211 on the other semicircular limiting plate 203. The mating hole 212 on the lower rotating disk 201 covers the drainage hole 211 on one of the semicircular limiting plates 203, and is aligned with the drainage hole 211 on the other semicircular limiting plate 203. That is, the spaces on both sides of the partition plate 202 are used to store the condensate drained into the collection bottle 20 by the three-way pipe 10, and to drain the condensate stored in the collection bottle 20 downwards.

[0024] Example 3: Please refer carefully to the attached diagram. Figures 1-5The partition plate 202 contains a drive assembly for rotating the rotating disk 201. The drive assembly includes fixed sleeves 207 on both sides of the partition plate 202, with piston plates 208 sliding inside each fixed sleeve 207. A rack 209 connects between each pair of piston plates 208, and a gear ring 210 meshes with one side of the rack 209. A rotating shaft 206 is rotatably mounted at the center of the partition plate 202, with the gear ring 210 fitted onto the rotating shaft 206. The upper and lower ends of the rotating shaft 206 are connected to the upper and lower rotating disks 201, respectively. The partition plate 202 contains a cavity to accommodate the gear ring 210, and the rack 209 passes through the partition plate 202 and its internal cavity. A vertical rod 204 connects between the upper and lower semi-circular limiting plates 203, with a floating plate top block 205 slidably mounted on the vertical rod 204. A hemispherical block 213 is connected to the side of the piston plate 208 away from the rack 209.

[0025] When the three-way pipe 10 discharges condensate into the collection bottle 20, the condensate falls into one half of the collection bottle 20. As the amount of condensate on that half increases, the float plate top block 205 will also move upward until the float plate top block 205 contacts the hemispherical block 213 and pushes the hemispherical block 213 into the fixed sleeve 207, thereby causing the rack 209 to move. The movement of the rack 209 will drive the rotating disk 201 to rotate, thus causing the rotating disk 201 to rotate half a revolution.

[0026] Example 4: Please refer carefully to the attached diagram. Figure 1 The outer surface of the collection bottle 20 is provided with a scale 214. Using the scale 214, the amount of condensate inside the collection bottle 20 can be accurately measured in real time, which is convenient for recording.

[0027] Working principle: When medical staff use it, they connect the three-way tube 10 to the ventilator's breathing circuit. At this time, the docking hole 212 on the upper rotating plate 201 is aligned with the drainage hole 211 on one of the semicircular limiting plates 203, covering the drainage hole 211 on the other semicircular limiting plate 203. The docking hole 212 on the lower rotating plate 201 covers the drainage hole 211 on one of the semicircular limiting plates 203, and is aligned with the drainage hole 211 on the other semicircular limiting plate 203. That is, the spaces on both sides of the partition plate 202 are used to store the condensate drained into the collection bottle 20 by the three-way tube 10 and to drain the condensate stored in the collection bottle 20 downwards. When the three-way pipe 10 discharges condensate into the collection bottle 20, the condensate falls into one half of the space in the collection bottle 20. As the amount of condensate in this half increases, the float plate top block 205 will also move upward until the float plate top block 205 contacts the hemispherical block 213 and pushes the hemispherical block 213 into the fixed sleeve 207, thereby causing the rack 209 to move. The movement of the rack 209 will drive the rotating disk 201 to rotate, thereby causing the rotating disk 201 to rotate half a revolution, so that the half space originally used for storing and transporting condensate will begin to discharge condensate. The condensate in the other side plate space has been drained and is used to collect condensate again.

[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
