AI Technical Summary
The existing drainage bottles lack control valves, which allows outside air to easily enter the pleural cavity, causing pneumothorax and infection. At the same time, the long catheter connection restricts patient movement and makes medical and nursing operations inconvenient.
A closed thoracic drainage bottle was designed, equipped with a drainage tube and a negative pressure tube. The end of the drainage tube is equipped with two switching valves and a suction head. The negative pressure tube is connected to a portable pressure regulator. The air isolation and negative pressure suction are controlled by the switching valves.
It effectively prevents air from entering the pleural cavity, improves the safety of drainage fluid specimen collection, allows patients to move freely, and simplifies medical and nursing procedures.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of closed thoracic drainage bottles, specifically a closed thoracic drainage bottle. Background Technology
[0002] The existing drainage bottles lack control valves, making it easy for external air to enter the drainage tube during pleural drainage collection, which can then travel along the tube into the pleural cavity, potentially causing pneumothorax and infection, and compromising aseptic technique. Furthermore, using negative pressure ventilation requires connecting a long catheter to the negative pressure machine. This external catheter hinders patient mobility and is also inconvenient for medical staff. Utility Model Content
[0003] The purpose of this invention is to provide a closed thoracic drainage bottle to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] This utility model discloses a closed thoracic drainage bottle, which includes a drainage bottle, a drainage tube, and a negative pressure tube. The drainage tube has two switching valves A at its end, and a suction head is provided between the two switching valves A. The negative pressure tube has a switching valve B, and the end of the negative pressure tube is connected to a portable pressure regulator.
[0006] As an improvement, the drainage bottle is equipped with a detachable carrying strap.
[0007] The advantages of this invention compared to existing technologies are as follows: When draining pleural effusion, the drainage tube is inserted into the pleural cavity, the drainage bottle collects the drainage fluid, the portable pressure regulator is activated, and valve B is opened to maintain negative pressure in the drainage bottle, which facilitates suction and collection of the drainage fluid. When it is necessary to collect a sample of the drainage fluid, first close valve A near the drainage bottle, then close the other valve A, leaving a section of drainage fluid between the two valves A. Then, a catheter is connected to the aspiration head to extract a portion of the drainage fluid as a sample.
[0008] The switch valve A acts as an air barrier, preventing air from entering the pleural cavity along the catheter and drainage tube, thus ensuring high safety in the collection of drainage fluid samples. The negative pressure tube is directly connected to a portable pressure regulator, eliminating the need for a long catheter and preventing interference with the patient's ability to get out of bed. Attached Figure Description
[0009] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings listed below are only some structural schematic diagrams of this utility model, and not all of them.

[0013] 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.
[0014] In the description of the embodiments of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0015] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance. The use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be perfectly horizontal, but can be slightly tilted.
[0016] In the description of the embodiments of this utility model, the terms "multiple" or "several" refer to at least two.
[0017] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0018] This embodiment is combined with the appendix Figure 1 This paper provides a detailed description of a closed thoracic drainage bottle.
[0019] This embodiment provides a closed thoracic drainage bottle, including a drainage bottle 1. The drainage bottle 1 is provided with a drainage tube 2 and a negative pressure tube 3. The end of the drainage tube 2 is provided with two switching valves A4, and a suction head 6 is provided between the two switching valves A4. The negative pressure tube 3 is provided with a switching valve B5, and the end of the negative pressure tube 3 is connected to a portable pressure regulator 7.
[0020] The drainage bottle 1 is equipped with a detachable carrying strap 8.
[0021] In practice, when draining pleural effusion, drainage tube 2 is inserted into the pleural cavity, drainage bottle 1 collects the drainage fluid, portable pressure regulator 7 is activated, and valve B5 is opened to maintain negative pressure in drainage bottle 1, which facilitates suction and collection of the drainage fluid. When it is necessary to collect a sample of the drainage fluid, first close valve A4 near drainage bottle 1, then close the other valve A4, leaving a section of drainage fluid between the two valves A4. Then, connect the suction head 6 with a catheter to extract a portion of the drainage fluid as a sample. Valve A4 serves to isolate air, preventing air from entering the pleural cavity along the catheter and drainage tube 2.
[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention.
