Description

Technical Field

[0001] This utility model relates to a ventilator condensate collection device, belonging to the field of medical device technology. Background Technology

[0002] In cold winter weather, the temperature difference between the gas inside the ventilator tubing and the outside air causes some of the heated gas to condense and form water. Since the air exhaled by patients with lung infections caused by pathogens often contains a large number of bacteria and viruses, this can lead to the proliferation of pathogens in the condensate, affecting the patient's recovery. Therefore, medical staff need to install a condensate collection cup on the ventilator tubing and empty it when it is two-thirds full before reinstalling it. However, this method of condensate collection has the following drawbacks: First, the condensate cup has a limited capacity; if not emptied promptly, the condensate can backflow into the ventilator tubing, increasing the incidence of ventilator-associated pneumonia. Second, the open condensate emptying process can easily generate aerosols, increasing the risk of hospital-acquired infections. Furthermore, the high frequency of condensate emptying increases the workload of medical staff and the amount of disposable gloves used.

[0003] To address this, Chinese patent document CN216824423U discloses a closed-loop collection device for ventilator condensate, comprising a condensate collection cup, manual valves, a storage bag, and a flexible tube. Both ends of the flexible tube are connected to one end of two manual valves, and the other ends of the two manual valves are connected to the drain port of the condensate collection cup and the inlet port of the storage bag, respectively. By using manual valves and a flexible tube to connect the condensate collection cup and the storage bag, the flow path of the condensate can be cut off by the manual valves before the storage bag can be replaced. This eliminates the problem of pathogen transmission caused by open pouring methods and allows for direct sample retention using the storage bag, making the operation convenient.

[0004] However, during the collection of condensate, the gas in the ventilator tubing can flow back into the ventilator tubing because the ventilator tubing is connected to the inside of the reservoir bag through the secondary tube, main tube, seat tube, guide tube, cup body and hose. This further contributes to the still high incidence of ventilator-associated pneumonia. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a ventilator condensate collection device.

[0006] This utility model is achieved through the following technical solution:

[0007] A ventilator condensate collection device includes a condensate cup and a collection bag. The condensate cup includes a cup body and a liquid-to-gas barrier assembly. The bottom of the cup body is provided with a liquid outlet pipe, and a valve A is installed on the liquid outlet pipe. One end of the liquid-to-gas barrier assembly is connected to one end of the liquid outlet pipe and is located inside the cup body. The collection bag includes a bag body and a liquid inlet pipe located at the top of the bag body. One end of the liquid inlet pipe is connected to the end of the liquid outlet pipe away from the cup body.

[0008] The liquid-to-gas barrier assembly is a pipe, and the pipe is S-shaped.

[0009] The inlet of the pipe is located below the outlet, and the inlet of the pipe is arranged close to the bottom plate of the cup body and is inclined upward relative to the bottom plate of the cup body.

[0010] The water collection cup also includes a cup lid and a ventilator three-way tube. The cup lid is detachably connected to the cup body, and the ventilator three-way tube is located on the cup lid and passes through the cup lid.

[0011] The inlet pipe and outlet pipe are threaded together.

[0012] Valve B is installed on the inlet pipe.

[0013] The top of the bag is equipped with a hanging loop.

[0014] The top of the bag is provided with a disinfectant injection port, and the bag is provided with a plug or sealing cap at the disinfectant injection port.

[0015] The shape and size of the bottom of the bag gradually decrease from top to bottom.

[0016] The bottom of the bag is provided with a drain pipe, and a valve C is installed on the drain pipe.

[0017] The beneficial effects of this invention are as follows: the liquid-blocking gas-blocking component located inside the cup and installed at one end of the liquid outlet tube can block gas and only allow condensate to flow, thereby preventing gas in the water collection bag from flowing back into the water collection cup or even the ventilator tubing, further reducing the incidence of ventilator-associated pneumonia.

Detailed Implementation

[0021] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0022] like Figure 1 and Figure 2 As shown, the present invention discloses a ventilator condensate collection device, comprising a water collection cup 1 and a water collection bag 2. The water collection cup 1 includes a cup body 12 and a liquid-to-gas barrier assembly 15. The bottom of the cup body 12 is provided with a liquid outlet pipe 14, and a valve A13 is installed on the liquid outlet pipe 14. One end of the liquid-to-gas barrier assembly 15 is connected to one end of the liquid outlet pipe 14 and is located inside the cup body 12. The water collection bag 2 includes a bag body 24 and a liquid inlet pipe 20 provided at the top of the bag body 24. One end of the liquid inlet pipe 20 is connected to the end of the liquid outlet pipe 14 away from the cup body 12. In use, the inlet tube 20 at the top of the bag 24 is connected to the outlet tube 14 at the bottom of the cup 12. After opening valve A13, the condensate in the cup 12 can be diverted into the bag 24, thus expanding the volume of the collection cup 1 through the collection bag 2. First, this avoids the condensate in the collection cup 1 from flowing back into the ventilator tubing due to untimely emptying, reducing the incidence of ventilator-associated pneumonia. Second, the condensate passage can be cut off by valve A13 before emptying the condensate in the collection bag 2 or directly replacing the collection bag 2, eliminating the problem of germ transmission caused by open condensate emptying and reducing the risk of hospital-acquired infections. Third, it reduces the frequency of condensate emptying, which helps reduce the workload of medical staff and the amount of disposable gloves used.

[0023] The liquid-to-gas barrier 15, located inside the cup body 12 and installed at one end of the liquid outlet tube 14, can block gas and only allow condensate to flow, thereby preventing gas in the water collection bag 2 from flowing back into the water collection cup 1 or even the ventilator tubing, further reducing the incidence of ventilator-associated pneumonia.

[0024] The liquid-to-gas barrier assembly 15 is a pipe, and the pipe is S-shaped. In use, condensate forms a water trap inside the S-shaped pipe, that is, the condensate remaining in the S-shaped pipe will cover its entire cross-section to block gas and allow only condensate to flow.

[0025] The inlet of the pipe is located below the outlet, close to the bottom plate of the cup body 12, and inclined upward relative to the bottom plate of the cup body 12. The inlet of the pipe is close to the bottom plate of the cup body 12 to discharge as much condensate as possible from the cup body 12; the inlet of the pipe is inclined upward relative to the bottom plate of the cup body 12 to prevent phlegm or other substances at the bottom of the cup body 12 from clogging the pipe.

[0026] The water collection cup 1 also includes a cup lid 11 and a ventilator three-way tube 10. The cup lid 11 is threadedly connected to the cup body 12, and the ventilator three-way tube 10 is located on the cup lid 11 and passes through the cup lid 11.

[0027] The inlet pipe 20 is threadedly connected to the outlet pipe 14, facilitating the installation and removal of the water collection bag 2.

[0028] A valve B21 is installed on the inlet pipe 20. Before separating the water collection bag 2 from the water collection cup 1, the valve B21 should be closed to reduce the generation of aerosols.

[0029] The top of the bag 24 is provided with a hanging ring 22. This allows the bag 24 to be easily suspended and fixed to the hospital bed via the hanging ring 22.

[0030] The top of the bag 24 is provided with a disinfectant inlet 23, and a plug or sealing cap is provided on the bag 24 at the disinfectant inlet 23. Disinfectant such as 84 disinfectant can be injected into the bag 24 through the disinfectant inlet 23 to disinfect the condensate inside the bag 24, further reducing the risk of hospital-acquired infections. The disinfectant inlet 23 is sealed with a plug or sealing cap.

[0031] The shape and size of the bottom of the bag 24 gradually decrease from top to bottom.

[0032] The bottom of the bag body 24 is provided with a drain pipe 25, and a valve C26 is installed on the drain pipe 25. This allows the condensate inside the bag body 24 to be drained through the drain pipe 25 by opening the valve C26.

[0033] The working principle or usage process of the ventilator condensate collection device of this utility model is as follows:

[0034] Connect the ventilator three-way tube 10 on the cup lid 11 to the ventilator tubing, then thread the cup body 12 to the cup lid 11 and close valve A13. Close valves B21 and C26, and inject 84 disinfectant or similar solution into the bag body 24 through the disinfectant inlet 23 to disinfect the condensate flowing into the bag body 24, further reducing the risk of hospital-acquired infection. Then close the disinfectant inlet 23 with a plug or sealing cap, and securely thread the inlet tube 20 to the outlet tube 14. Finally, suspend and fix the bag body 24 to the hospital bed using the hanging ring 22.

[0035] After the ventilator is started, when the condensate in cup 12 submerges the inlet of the S-shaped tube, the condensate forms a backflow trap within the S-shaped tube. Then, valves A13 and B21 are opened. When the condensate level in cup 12 rises to a certain height, the condensate enters bag 24 through the S-shaped tube, outlet tube 14, and inlet tube 20. During the condensate collection process, the backflow trap formed within the S-shaped tube blocks gas flow, allowing only condensate to flow, thus preventing gas in the collection bag 2 from flowing back into the collection cup 1 or even the ventilator tubing, further reducing the incidence of ventilator-associated pneumonia.

[0036] When the amount of condensate in the water collection bag 2 exceeds 3 / 4 of its volume, close valves A13 and B21, open valve C26 to drain the condensate in the water collection bag 2, and then put it back in its original position, or replace the water collection bag 2 directly.
