[0002] For the treatment of laryngeal cancer, neck lymph node dissection for laryngeal cancer is one of the more effective surgical methods. At present, in order to prevent complications such as hematoma and exudate accumulation after surgery, drainage is required after laryngeal cancer neck lymph node dissection. The accumulated fluid and blood coagulation are discharged through the drainage ball device. The insertion end of the drainage tube is inserted into the surgical wound, and the drainage ball is squeezed to form negative pressure, thereby continuously drawing out gas or liquid from the wound to ensure the cleanliness of the wound and promote wound healing.

[0003] Since wound secretions, blood clots, etc. will continue to be produced to a certain extent, patients need to wear drainage balls for a long time for drainage. During the hospitalization and rehabilitation period, medical staff often need to observe the color of the accumulated fluid in the drainage ball and compare it with the colorimetric card in order to take corresponding follow-up treatment measures. Independent colorimetric cards are inconvenient to store and easy to lose. Although there are colorimetric cards printed or pasted on the surface of the drainage ball to facilitate medical staff's observation, the liquid in the drainage ball may accidentally flow out during the process of medical staff draining the fluid or re-squeezing the drainage ball to form negative pressure, causing contamination to the colorimetric card, resulting in poor comparison effect, and thus requiring continuous replacement of new drainage balls, which is more cumbersome.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, an embodiment of the utility model provides a negative pressure drainage device, including a drainage tube body 1 and a drainage ball body 2 installed at one end thereof, and also includes a bracket 3. The bracket 3 is in a "U" shape and can be hung on both sides of a hospital bed. A movable plate 33 for positioning the drainage ball body 2 is installed on the surface of the bracket 3. A clamping block 22 is fixedly connected to the surface of the drainage ball body 2. The clamping block 22 is in an "L" shape. A positioning block 332 adapted to the clamping block 22 is fixedly connected to the surface of the movable plate 33. The positioning block 332 is in a "U" shape. The clamping block 22 can be stuck in the "U"-shaped groove on the surface of the positioning block 332, so as to fix the entire drainage ball body 2. A colorimetric plate 341 is arranged on the surface of the movable plate 33. The colorimetric plate 341 is a plate with magnetization characteristics. A magnetic block 221 is fixedly connected to the surface of the clamping block 22, and can be connected to the colorimetric plate 341 through the magnetic block 221.

[0025] Specifically, the colorimetric plate 341 is magnetically connected to the surface of the block 22 to facilitate color comparison. However, when the drainage ball body 2 is being drained or the negative pressure is restored, the colorimetric plate 341 can be selected not to be connected to the surface of the block 22 to avoid contamination of the colorimetric plate 341.

[0026] like Figure 3 and Figure 4As shown, in the present embodiment, further, connecting blocks 342 are fixedly connected on both sides of the colorimetric plate 341, and an inclined groove 333 adapted to the connecting block 342 is provided on the surface of the positioning block 332, and the connecting block 342 can be limitedly slid in the inclined groove 333. When the block 22 is stuck on the surface of the positioning block 332, the connecting block 342 separates the colorimetric plate 341 from the block 22 under the restriction of the inclined groove 333. Therefore, each time the drainage ball body 2 together with the block 22 is placed on the surface of the positioning block 332, the colorimetric plate 341 will be separated from the block 22, so that it is convenient to choose whether to connect the colorimetric plate 341 when the drainage ball body 2 is taken out next time.

[0027] Among them, a color card 343 for comparing the color of secretions is arranged on the surface of the color comparison plate 341. The color card 343 can be set to a variety of colors, and the corresponding measures or symptoms can be filled in after the corresponding colors to improve the judgment efficiency of medical staff.

[0028] Furthermore, in this embodiment, a protective plate 34 for protecting the color comparison plate 341 and the color card 343 is fixedly connected to the surface of the movable plate 33. The protective plate 34 blocks and protects the color comparison plate 341 and the color card 343 on its surface to avoid contamination of the color card 343 due to unexpected situations.

[0029] Further, such as Figure 5 As shown, in this embodiment, a slide groove is provided on the surface of the bracket 3, and the movable plate 33 slides in the slide groove. A stopper 31 for limiting the movable plate 33 is rotatably connected to the top of the bracket 3.

[0030] The movable plate 33 is connected to the bracket 3 via a spring 32 , and two ends of the spring 32 are fixedly connected to the movable plate 33 and the bracket 3 respectively.

[0031] Specifically, when the patient needs to get out of bed to perform other activities, the block 31 is rotated to remove its obstruction to the movable plate 33. In this way, under the action of the rebound force of the spring 32, the movable plate 33 will be popped up, raising the height of the drainage ball body 2, making it convenient for the patient to access the drainage ball body 2 located on the surface of the movable plate 33. Similarly, when the patient returns to the bed, the drainage ball body 2 can be stuck into the surface of the positioning block 332, and the movable plate 33 can be pressed down to compress the spring 32. Finally, the block 31 is rotated to move the movable plate 33 downward without hindering the patient's activities on the bed surface.

[0032] A fluorescent plate 331 is provided on the surface of the movable plate 33. By providing the fluorescent plate 331, medical staff can turn off the lights at night and find the position of the movable plate 33 more conveniently without disturbing the patient's rest, and correspondingly find the position of the drainage ball body 2.

[0033] The surface of the drainage ball body 2 is provided with scale lines 21, which are used to mark the liquid level inside the drainage ball body 2. The scale lines 21 are divided into a middle section and a lower section. The spacing between adjacent scale lines in the middle section of the scale lines 21 is greater than the spacing between adjacent scale lines in the lower section, that is, the closer the number of scale lines 21 is to the bottom of the drainage ball body 2, the denser they are. This makes it easy to mark the liquid level even when the drainage ball body 2 contains only a small amount of liquid, which is suitable for situations such as less drainage fluid in the later stage.

[0034] In a further embodiment, a movable section 11 is installed at one end of the drainage tube body 1 away from the drainage ball body 2, and the movable section 11 is arc-shaped. An insertion section 12 is installed at one end of the movable section 11. Specifically, the insertion section 12 is used to be inserted into the patient's wound to perform drainage operations in the wound, and the movable section 11 is set to be arc-shaped, so as to reserve activity redundancy for the patient and avoid pulling or loosening of the drainage tube body 1 due to the patient's body activities.

[0035] Among them, at least one group of medical tapes 13 are arranged on the surface of the drainage tube body 1. The medical tapes 13 are fluorescent tapes. The medical tapes 13 can not only fix the drainage tube body 1, but also be set to fluorescent type, which is also convenient for medical staff to observe in time at night.

[0036] Working principle:

[0037] When in use, first hang the bracket 3 on either side of the bed, and fix the bracket 3 by gluing, screwing, etc., then clamp the block 22 on the surface of the drainage ball body 2 on the positioning block 332, and the drainage ball body 2 can be placed. When the medical staff needs to take the drainage ball body 2, they only need to remove the block 22 from the surface of the positioning block 332 to completely take out the drainage ball body 2. When taking out the drainage ball body 2, you can choose whether to take out the colorimetric plate 341. In the process of taking out the block 22 upward, the colorimetric plate 341 is simultaneously pressed toward the direction of the block 22 until the colorimetric plate 341 is adsorbed on the magnetic block 221. At this time, the color of the solution inside the drainage ball body 2 can be compared to make subsequent treatment measures. When the patient needs to take out the drainage ball body 2 when getting off the bed, he only needs to rotate the block 31. Under the rebound force of the spring 32, the movable plate 33 is popped up, raising the height of the drainage ball body 2, which is convenient for the patient to take.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
