[0002] Chest lavage is a common treatment method in clinical practice, mainly for the treatment of empyema, chest infection, bronchopleural fistula and other diseases. The main purpose is to flush the chest cavity and reduce bacterial growth in the chest cavity. During the chest lavage process, a chest drainage and lavage suction device is required.

[0003] In the Chinese utility model patent with the announcement number CN219721488U, a simple flushing and suction device is disclosed. When adjusting the relative telescopic position of the outer tube and the inner tube, the outer tube can be moved along the inner tube in the axial position, and the telescopic tube is adaptively extended or shortened. The overall structure of the device is simple, the operation and adjustment are convenient, and the external connecting pipeline will not be twisted.

[0004] However, combined with the clinical experience of chest flushing care, the above scheme is found to still have some defects and shortcomings. First, the water outlet and the water inlet are located at the same place. During the flushing process, it is easy for the clean water just sprayed to be sucked away by the negative pressure. The flushing direction cannot be adjusted, and there is a problem of insufficient flushing. Moreover, based on the requirements of hygiene and safety, the current flushing and drainage tubes are all disposable items, but the above device does not have a disassembly function and is not convenient for multiple use. Therefore, it is urgent to improve the existing chest drainage flushing and suction device and provide a chest drainage flushing and suction device. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A chest drainage, flushing and suction device comprises a mounting tube, a flushing tube and a negative pressure suction tube, wherein the mounting tube has two symmetrical channels formed inside, wherein the flushing tube and the negative pressure suction tube are respectively installed in the two channels, wherein a sleeve is threadedly sleeved on the top outer side of the mounting tube, a connecting block is installed on the top inner side bearing of the sleeve, a traction assembly is fixedly connected to the interior of the connecting block, and a positioning assembly is sleeved on the top outer side of the traction assembly.

[0008] As a preferred embodiment, an arc portion is provided at the bottom of the hole, and the arc portions at the bottom of the two holes have opposite bending directions.

[0009] As a preferred embodiment, the top outer wall of the mounting tube and the bottom inner wall of the sleeve are provided with mutually matching threaded structures.

[0010] As a preferred embodiment, the traction assembly includes a traction tube, a clamping sleeve and a ring. The two traction tubes are symmetrically arranged about the center line of the connecting block. The two traction tubes both penetrate the interior of the connecting block and are fixedly connected to the connecting block. The top ends of the two traction tubes are bonded with a clamping sleeve, and the outer sides of the top ends of the two traction tubes are bonded with a ring.

[0011] As a preferred embodiment, the bottom end of the traction tube extends to the inner side of the channel, and the traction tube is slidably connected to the mounting tube. The clamping sleeve and the ring are both made of rubber, and the thickness of the clamping sleeve is set to decrease from bottom to top.

[0012] As a preferred embodiment, the positioning assembly includes a positioning cover, a through hole, an extrusion portion and an annular groove. Through holes are provided inside the left and right ends of the positioning cover, an extrusion portion is provided in the middle of the through hole, and an annular groove is provided on the inner wall of the bottom end of the through hole.

[0013] As a preferred implementation, the inner diameter of the extrusion portion is arranged to increase from top to bottom, and the annular groove and the collar are adapted to each other.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the solution of the utility model:

[0016] By manually rotating the sleeve, the sleeve can drive the connecting block, the traction assembly, the flushing tube and the negative pressure suction tube to move downward synchronously for adjustment. Under the action of the arc-shaped portion at the bottom of the channel, the extended flushing tube and the bottom of the negative pressure suction tube can be bent, and the bending directions of the two are opposite, which is not only convenient for adjusting the flushing direction, but also can increase the distance between the water outlet and the water inlet, avoid the fresh water just sprayed from being sucked out, ensure sufficient flushing, and facilitate flushing and suction at the same time;

[0017] After flushing is completed, the positioning cover can be pulled out forcefully from the outside of the top of the traction tube. After losing the squeezing of the squeezing part, the clamping sleeve can be restored by its own elastic force and disengaged from the flushing tube and the negative pressure suction tube, so that the flushing tube and the negative pressure suction tube can be pulled out and the installation tube can be disinfected. Compared with the comparative documents, the flushing tube and the negative pressure suction tube in this application can be disassembled and replaced separately, the device main body can be used multiple times, and the practicality is stronger.

[0027] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0028] like Figure 1-6 As shown, the utility model chest drainage flushing and suction device comprises a mounting tube 1, a flushing tube 8 and a negative pressure suction tube 9. The mounting tube 1 has two symmetrical channels 2 in its interior, in which the flushing tube 8 and the negative pressure suction tube 9 are respectively installed. A sleeve 4 is threadedly sleeved on the top outer side of the mounting tube 1, a connecting block 5 is installed on the top inner side bearing of the sleeve 4, a traction assembly 6 is fixedly connected to the interior of the connecting block 5, and a positioning assembly 7 is sleeved on the top outer side of the traction assembly 6.

[0029] On the basis of the above structure, an arc-shaped portion 3 is provided at the bottom of the hole 2, and the arc-shaped portions 3 at the bottom of the two holes 2 have opposite bending directions.

[0030] In this embodiment, the arc-shaped portion 3 at the bottom of the channel 2 is provided to facilitate guiding the downwardly moving flushing tube 8 and negative pressure suction tube 9 to bend, thereby realizing convenient adjustment of the flushing direction.

[0031] On the basis of the above structure, the top outer wall of the mounting tube 1 and the bottom inner wall of the sleeve 4 are provided with mutually matching threaded structures.

[0032] In this embodiment, due to the threaded connection between the mounting tube 1 and the sleeve 4, it is convenient to control the synchronous downward movement and adjustment of the connecting block 5, the traction assembly 6, the flushing tube 8 and the negative pressure suction tube 9 by rotating the sleeve 4.

[0033] On the basis of the above structure, the traction assembly 6 includes a traction tube 61, a clamping sleeve 62 and a ring 63. The two traction tubes 61 are symmetrically arranged about the center line of the connecting block 5. The two traction tubes 61 both penetrate the interior of the connecting block 5 and are fixedly connected to the connecting block 5. The top ends of the two traction tubes 61 are bonded with the clamping sleeve 62, and the outer sides of the top ends of the two traction tubes 61 are bonded with a ring 63.

[0034] In this embodiment, the clamping sleeve 62 is provided to facilitate clamping and positioning of the flushing tube 8 and the negative pressure suction tube 9 by the positioning assembly 7 .

[0035] Based on the above structure, the bottom end of the traction tube 61 extends to the inner side of the channel 2, and the traction tube 61 is slidably connected to the mounting tube 1. The clamping sleeve 62 and the ring 63 are both made of rubber, and the thickness of the clamping sleeve 62 is set to decrease from bottom to top.

[0036] In this embodiment, since the bottom end of the traction tube 61 extends into the channel 2, when the rotating sleeve 4 is controlled, the traction tube 61 as well as the flushing tube 8 and the negative pressure suction tube 9 can be controlled to move downward stably.

[0037] Based on the above structure, the positioning assembly 7 includes a positioning cover 71, a through hole 72, an extrusion portion 73 and an annular groove 74. Through holes 72 are provided inside the left and right ends of the positioning cover 71, an extrusion portion 73 is provided in the middle of the through hole 72, and an annular groove 74 is provided on the inner wall of the bottom end of the through hole 72.

[0038] In this embodiment, when the positioning cover 71 is put on the outer side of the top of the traction tube 61, the extrusion part 73 can be used to squeeze the clamping sleeve 62, so that the diameter of the port of the clamping sleeve 62 is compressed and reduced, which is convenient for clamping and positioning the flushing tube 8 and the negative pressure suction tube 9.

[0039] On the basis of the above structure, the inner diameter of the extrusion portion 73 is arranged to increase from top to bottom, and the annular groove 74 and the collar 63 are adapted to each other.

[0040] In this embodiment, the annular groove 74 and the collar 63 are provided to facilitate the stable installation of the positioning cover 71 on the outer side of the top of the traction tube 61 .

[0041] The working principle of the utility model is as follows:

[0042] When in use, first insert the flushing tube 8 and the negative pressure suction tube 9 into the inner walls of the two traction tubes 61 respectively and extend them into the channel 2, then the positioning cover 71 is installed on the outer side of the top of the traction tube 61 through the annular groove 74 on the inner wall of the bottom end and the rubber ring 63, at this time, the squeezing part 73 on the inner wall of the middle part of the positioning cover 71 can squeeze the rubber clamping sleeve 62, so that the clamping sleeve 62 is compressed and clamps and positions the flushing tube 8 and the negative pressure suction tube 9, then the bottom of the installation tube 1 can be extended into the patient's chest cavity, and water supply and cleaning and negative pressure suction are started at the same time, and the flushing speed is fast and the efficiency is high;

[0043] Before flushing, the sleeve 4 can be manually rotated according to actual needs, so that it drives the connecting block 5, the traction assembly 6, the flushing tube 8 and the negative pressure suction tube 9 to move downward synchronously for adjustment. Under the action of the arc-shaped portion 3 at the bottom of the channel 2, the bottoms of the extended flushing tube 8 and the negative pressure suction tube 9 can be bent, and the bending directions of the two are opposite, which is not only convenient for adjusting the flushing direction, but also can increase the distance between the water outlet and the water inlet, avoid the fresh water just sprayed from being sucked out, and ensure sufficient flushing;

[0044] After flushing is completed, the positioning cover 71 can be detached from the traction tube 61, so that the clamping sleeve 62 can be restored and the positioning of the flushing tube 8 and the negative pressure suction tube 9 can be released, so that the flushing tube 8 and the negative pressure suction tube 9 can be disassembled and replaced, and the installation tube 1 can be disinfected. The main body of the device can be used multiple times, saving costs and being more practical.
