Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a telescopic chest flushing tube. Background Art

[0002] Chest lavage is a common treatment method in clinical practice, mainly used to treat empyema, chest infection, bronchopleural fistula and other diseases. The main purpose is to flush the chest cavity, reduce bacterial growth in the chest cavity, culture pleural fluid, and observe the efficacy.

[0003] The inner tube of the existing chest lavage tube is fixed, and the lavage range is relatively limited. It can only lavage around the tube mouth, but not the distal end. The lavage effect is average, and the inner tube occupies the space of the chest lavage tube, which is not conducive to drainage and easily causes tube blockage. Secondly, after injecting drugs through the chest tube and before removing the tube, a clamping test is required, and the chest tube needs to be clamped. The current clamping method is the double clamping method, which will leave part of the drug in the tube cavity and cannot be fully retained in the body, resulting in drug waste and reduced treatment effect. After double clamping, the weight of the vascular clamp reduces the patient's comfort and easily causes the problem of tube removal.

[0004] In summary, the existing structure has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of the utility model is to provide a retractable chest flushing tube, in which one end of the flushing outlet of the inner tube can be extended or retracted into the interior of the outer tube, thereby increasing the range of chest flushing according to needs, and the inner tube can also expand inside the outer tube to meet the need of tube blocking.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] It should also be pointed out that the terms used in the present invention, such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top”, “bottom”, “vertical”, “horizontal”, etc., to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0021] See also Figure 1 to Figure 4 In one embodiment of the utility model, a retractable chest flushing tube 100 is provided, comprising an outer tube 10 and an inner tube 20; the outer tube 10 comprises a drainage inlet 11 and a drainage outlet 12 which are connected and arranged at both ends of the axial direction thereof, and an inner tube inlet 13 is opened on the tube wall; the inner tube 20 is a double-channel structure, comprising an inner channel 21 and an outer channel 22, and the outer channel 22 is arranged on the outer side of the inner channel 21; a flushing inlet 211 and a flushing outlet 212 are connected and arranged at both ends of the inner channel 21; a water bag 221 is arranged at one end of the outer channel 22 close to the flushing outlet 212, and a water injection inlet 222 connected to the water bag is arranged at the other end; one end of the inner tube 20 provided with the flushing outlet 212 is placed in the outer tube 10 through the inner tube inlet 13.

[0022] In this embodiment, the chest flushing tube 100 can not only flush the patient's chest cavity, but also draw out the effusion in the patient's chest cavity. Specifically, the outer tube 10 is used to draw out the liquid from the chest cavity, and the inner tube 20 is used to inject liquid such as medicine or flushing liquid to flush the patient's chest cavity. One end of the inner tube 20 provided with a flushing outlet 212 is inserted into the outer tube 10 through the inner tube inlet 13, and the inner tube 20 after insertion can slide inside the outer tube 10. When it is necessary to flush the patient's chest cavity, the end of the chest flushing tube 100 with the flushing outlet 212 is inserted into the patient's chest cavity, that is, one end of the flushing outlet 212 extends from the drainage inlet 11 of the outer tube 10 to reach the chest cavity, and liquids such as medicine or flushing liquid can be injected into the inner channel 21 of the inner tube 20 through the flushing inlet 211 by a syringe, and then injected into the patient's chest cavity through the flushing outlet 212. The flushing inlet 211 can be optionally set as a syringe connector, so that the liquid is injected into the inner channel 21 using a syringe, and the liquid in the inner channel 21 can also be prevented from flowing back out from the flushing inlet 211. When the tube needs to be closed after the drug is injected into the patient's chest cavity, the inner tube 20 is retracted into the inner part of the outer tube 10, and then the physiological saline or gas can be injected into the outer channel 22 through the water injection inlet 222 by a syringe to reach the water bag 221. Optionally, the water bag 221 is made of an elastic material, such as a silicone rubber material. After the water bag 221 is injected with water or inflated, it expands and fills the inner part of the outer tube 10 to prevent the drug in the chest cavity from flowing out. Optionally, the water injection inlet 222 is set as a syringe connector to facilitate the use of a syringe to inject liquid into the outer channel 22, and it can also prevent the liquid in the outer channel 22 from flowing back out from the water injection inlet 222. When it is necessary to drain the effusion in the patient's chest cavity, the water or gas in the water bag 221 is extracted, and then the inner tube 20 inside the outer tube 10 is moved to the inner tube inlet 13 to prevent the inner tube 20 from blocking the liquid in the patient's chest cavity from flowing out from the drainage inlet 11 to the drainage outlet 12.

[0023] See also Figure 3 As an optional embodiment, the outer tube 10 is provided with a first developing line 14 along its axial direction. The first developing line 14 can be displayed under X-rays, which is convenient for medical staff to operate the outer tube 10 in the chest cavity of the patient.

[0024] See also Figure 4 As an optional embodiment, the outer wall of the outer channel 22 is provided with a second developing line 23 along its axial direction. The second developing line 23 can be displayed under X-ray, which is convenient for medical staff to operate the inner tube 20 in the chest cavity of the patient.

[0025] See also Figure 2As an optional embodiment, the portion of the inner tube 20 exposed outside the outer tube 10 is covered with a sterile bag 30. One end of the sterile bag 30 is sealed to the outer wall of the outer tube 10, and the other end is sealed to the outer wall of the inner tube 20. The sterile bag 30 has enough margin so that the inner tube 20 can slide inside the outer tube 10.

[0026] See also Figure 1 to Figure 3 As an optional embodiment, an inner tube accommodating cavity 15 is extended outward from the position of the outer tube 10 corresponding to the inner tube inlet 13 , and the inner diameter of the inner tube accommodating cavity 15 is less than or equal to the inner diameter of the outer tube 10 .

[0027] In this embodiment, when the pleural effusion of the patient needs to be drained, the inner tube 20 inside the outer tube 10 is first placed in the inner tube accommodating cavity 15, and then the water bag 221 is filled with water to expand and fill the inner tube accommodating cavity 15, so as to prevent the liquid from overflowing from the inner tube inlet 13 during drainage.

[0028] As an optional embodiment, the outer tube 10 is made of silicone, rubber or silicone rubber material.

[0029] As an optional embodiment, the inner tube 20 is made of silicone, rubber or silicone rubber material.

[0030] In summary, a retractable chest flushing tube is provided in an embodiment of the utility model, and one end of the flushing outlet of the inner tube can extend or retract into the interior of the outer tube, thereby increasing the range of chest flushing according to needs, and the inner tube can also expand inside the outer tube to meet the needs of tube blocking.

[0031] Of course, the present invention may have many other embodiments.
