[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a sputum collection device for ventilator tubing, such as... Figures 1-3 As shown, the device includes a collection tank 1, with a detachable top cover 11 on the top. Both sides of the top of the top cover 11 are connected to oxygen tubing 3 via tracheal inlets 111. A negative pressure inlet 13 is provided on the top of one side of the collection tank 1, and a drain outlet 12 is provided on the bottom of the other side of the collection tank 1. A detachable water collection cup 2 is connected to the bottom of the collection tank 1. One oxygen tubing 3 is connected to the patient's breathing port, and the other oxygen tubing 3 is used to connect to the ventilator tubing. A negative pressure device is connected to the negative pressure inlet 13 to inhale the sputum sprayed into the corresponding oxygen tubing 3 into the collection tank 1.

[0023] In use, the device includes a collection container 1 with a detachable top cover 11, a design that facilitates disassembly and cleaning. Two oxygen tubing lines 3 are connected to the top of the top cover 11 via tracheal inlets 111 on both sides, ensuring that sputum can smoothly enter the collection system from the patient's airway through the oxygen tubing. An external negative pressure device is connected via a negative pressure inlet 13 to provide power for sputum inhalation. A drain port 12 facilitates the periodic removal of collected sputum, keeping the device clean. A water collection cup 2 collects and stores moisture from the sputum, preventing spillage and environmental contamination. A sealing cap is fitted to the outside of the drain port 12.

[0024] Through the synergistic effect of the above structures, the device can effectively draw the sputum sprayed into the oxygen tubing 3 by the patient into the collection canister 1, avoiding contamination of the ventilator tubing by the sputum, keeping the tubing clean and unobstructed, while reducing the workload of medical staff, improving work efficiency and the patient's treatment experience.

[0025] In this embodiment, a negative pressure pipeline 14 is vertically arranged inside the collection tank 1. The top end of the negative pressure pipeline 14 is connected to the negative pressure interface 13, and the bottom end of the negative pressure pipeline 14 is provided with an air inlet 15. This structure ensures that the external negative pressure device can smoothly transmit negative pressure to the inside of the collection tank 1. Thus, sputum can be effectively drawn into the collection tank 1 under the action of negative pressure.

[0026] Specifically, the air inlet head 15 is a spherical structure with an internal cavity, and its outer surface is provided with several air inlet holes. This structure increases the air intake area and improves the efficiency of sputum aspiration. At the same time, the spherical structure design also makes the air inlet head 15 more stable inside the collection container 1, and less prone to clogging or displacement.

[0027] Furthermore, a protective plate 16 is provided inside the collection tank 1 and outside the air inlet head 15. One side of the protective plate 16 has an opening, and a removable filter screen 17 is installed at the opening. This structure can effectively prevent solid particles or impurities in sputum from entering the negative pressure pipeline, protecting the normal operation of the negative pressure equipment, and also facilitating the cleaning and replacement of the filter screen 17.

[0028] Furthermore, the outer wall of the water collection cup 2 is provided with graduation lines 21. This structure allows medical staff to visually observe the water volume in the water collection cup 2, thereby promptly determining whether drainage is necessary and avoiding environmental pollution caused by water overflow.

[0029] Furthermore, the top of the water collection cup 2 is provided with a threaded interface 22, and the bottom of the collection tank 1 is provided with an internal threaded opening, with the bottom of the collection tank 1 threadedly connected to the water collection cup 2. This structure makes the connection between the water collection cup 2 and the collection tank 1 more secure and less prone to falling off, while also facilitating the disassembly and cleaning of the water collection cup 2.

[0030] Furthermore, a baffle 23 is installed inside the threaded interface 22 at the top of the collection tank 1. This structure effectively prevents external debris or dust from entering the water collection cup 2, keeping the water collection cup 2 clean and hygienic.

[0031] Furthermore, the endotracheal inlet 111 is sealed with a cap when not connected to the oxygen line 3. This structure ensures that the collection tank 1 remains sealed when not in use, preventing the entry of external contaminants and protecting the endotracheal inlet from damage.

[0032] When using the sputum collection device for ventilator tubing of this utility model, the device first includes a collection tank 1, the top of which is detachably fitted with a top cover 11. Two oxygen tubing 3 are connected to both sides of the top of the top cover 11 through tracheal inlets 111. At this time, the tracheal inlets 111 (when not connected to oxygen tubing 3) are tightly closed with a sealing cap to maintain a sealed state and prevent external contaminants from entering.

[0033] When a patient is using a ventilator, one oxygen tubing 3 is connected to the patient's breathing port, and the other oxygen tubing 3 is connected to the ventilator tubing, which is connected to a negative pressure device via a negative pressure interface 13. After the negative pressure device is activated, negative pressure is transmitted through the negative pressure interface 13 to the negative pressure tubing 14, and then to the air inlet head 15. Because the air inlet head 15 is designed with several air inlets, sputum is effectively drawn into the collection container 1 under negative pressure. After the sputum enters the collection container 1, some moisture is collected and stored in the water collection cup 2 to prevent overflow and environmental pollution. Simultaneously, solid particles or impurities in the sputum are filtered out by the filter screen 17 on the protective plate 16, protecting the normal operation of the negative pressure device.

[0034] The collected sputum is periodically drained through the drain port 12 to keep the device clean. When it is necessary to clean or replace the filter screen 17, the top cover 11 can be removed for easy cleaning and maintenance of the inside of the collection tank 1. The water collection cup 2 can also be separated from the collection tank 1 through the threaded interface 22 for easy cleaning and drainage.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
