Drainage bags for colorimetric analysis in hepatobiliary surgery Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a drainage bag used for colorimetric analysis in hepatobiliary surgery. Background Technology

[0002] Most patients with digestive system diseases such as hepatobiliary and pancreatic diseases have drainage tubes placed after surgery. The color of the drainage fluid varies depending on the drainage site, composition, and duration of indwelling. These color differences can be significant, requiring timely observation of the drainage tubes and changes in the drainage fluid's color. Achieving objective and consistent observation and recording by medical staff becomes a major challenge, and the care and observation of postoperative drainage tubes by patients and their families is even more difficult. Currently used drainage bags typically have colorimetric blocks printed directly on the transparent outer wall of the bag, facilitating quick comparison by medical staff. However, the large number of colors on the colorimetric blocks introduces significant errors during comparison, causing considerable inconvenience for users. Therefore, a drainage bag specifically designed for hepatobiliary surgery that allows for convenient color comparison is needed to address these issues. Summary of the Invention

[0022] 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.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to Figures 1-4.

[0024] Example 1, as shown in Figures 1-4, includes a bag 1 for storing drainage fluid. In order to make a direct judgment on the condition of the patient's drainage fluid, a hanging ring 2 is provided on the upper side of the bag 1. A fixing mechanism 3 is fixedly connected to the front and rear sides of the bag 1. A rotatable colorimetric mechanism 4 is provided on the front side of the bag 1. Multiple storage bags 5 are fixedly connected to the front side wall inside the bag 1. A contrast sleeve 6 is connected to the front side of each storage bag 5. The colorimetric mechanism 4 and the contrast sleeve 6 cooperate with each other to form a structure for judging the color of the drainage fluid.

[0025] In use, the bag body 1 can be suspended and fixed by the suspension ring 2 and the fixing mechanism 3. After connecting the upper side of the bag body 1 to the patient's drainage tube, normal drainage can be carried out. During the drainage process, medical staff can let the drainage fluid enter the corresponding storage bag 5 as needed. Then, the drainage fluid for that period of time will first enter the corresponding drainage bag. Afterwards, the color of the drainage fluid in the storage bag 5 can be carefully observed and compared by the comparison sleeve 6. Through the colorimetric mechanism 4, a preliminary judgment can be made on the different colors of drainage fluid, reducing the risk of missed diagnosis by medical staff.

[0026] Furthermore, as shown in Figures 1-4, in order to facilitate the differentiation of drainage fluids at different time periods, an inlet pipe 7 is connected to the upper side of the bag body 1, and an adjusting pipe 8 is connected to the lower side of the inlet pipe 7. An isolation plate 9 is fixedly connected inside the bag body 1. An inlet hole 10 corresponding to the colorimetric block 18 is opened on the isolation plate 9. A connecting pipe 11 is connected to the lower side of each inlet hole 10. The lower side of each connecting pipe 11 is connected to the corresponding storage bag 5. The adjusting pipe 8 and the corresponding inlet hole 10 cooperate with each other to form a structure in which the inlet pipe 7 is connected to the corresponding storage bag 5.

[0027] In use, the inlet tube 7 is connected to the patient's drainage tube. During the drainage process, the drainage fluid through the drainage tube will enter the corresponding inlet hole 10 through the regulating tube 8, and then enter the corresponding storage bag 5 through the corresponding connecting tube 11. When it is necessary to introduce the drainage fluid into other storage bags 5, medical staff can squeeze the bag body 1 to move the position of the regulating tube 8. By coordinating the regulating tube 8 with the corresponding inlet hole 10, the delivery position of the drainage fluid can be adjusted.

[0028] Furthermore, as shown in Figures 1-4, in order to increase the smoothness of drainage, a first magnetic ring 12 is fixedly connected to the outer side of the bottom of the regulating tube 8, and a second magnetic ring 13 is fixedly connected to the outer side of each liquid inlet hole 10 on the isolation plate 9. The first magnetic ring 12 and the corresponding second magnetic ring 13 cooperate with each other to form a structure in which the regulating tube 8 is connected to the corresponding connecting tube 11.

[0029] In use, the first magnetic ring 12 and the second magnetic ring 13 are both made of magnetic material and can attract each other under the action of magnetic force, thereby maintaining the connection between the regulating tube 8 and the corresponding liquid inlet hole 10, and making it less likely to loosen or fall off.

[0030] Furthermore, as shown in Figures 1-4, in order to preserve the color of the drainage fluid at different time periods, each storage bag 5 is provided with a cotton rope 14 on the front side, the lower end of each cotton rope 14 is placed inside the comparison sleeve 6, and the upper end of each cotton rope 14 is placed inside the corresponding storage bag 5.

[0031] When in use, when the storage bag 5 contains drainage fluid, the drainage fluid is introduced into the interior of the comparison sleeve 6 by the capillary action of the cotton rope 14. Since the liquid transport capacity of the capillary action is limited, the amount of liquid inside the comparison sleeve 6 is also less diluted. In other words, after a certain amount of drainage fluid is stored inside the comparison sleeve 6 by the capillary action of the cotton rope 14, it is less affected by subsequent drainage fluid, thus achieving the purpose of preserving drainage fluid for a specific time period.

[0032] Furthermore, as shown in Figures 1-4, in order to better store the drainage fluid, a connecting hole 15 is provided on the upper part of the rear side of each storage bag 5;

[0033] When in use, after a certain amount of drainage fluid is stored in the storage bag 5, the drainage fluid will overflow from the storage bag 5 through the connecting hole 15 and then be stored in the bag body 1, increasing the storage capacity of the drainage fluid.

[0034] Furthermore, as shown in Figures 1-4, in order to facilitate the comparison of the color of the drainage fluid, the colorimetric mechanism 4 includes a rotating disk 16 and a colorimetric disk 17. The front side of the colorimetric disk 17 is provided with multiple color blocks 18 for color comparison. The colorimetric disk 17 is detachably connected to the front side of the rotating disk 16. A mushroom head 19 is fixedly connected to the rear side of the rotating disk 16. The middle part of the mushroom head 19 is rotatably connected to the corresponding fixing mechanism 3.

[0035] When in use, the colorimetric disk 17 can be replaced with a colorimetric disk 17 of the corresponding model as needed. The colorimetric disk 17 and the rotating disk 16 are detachably connected by adhesive tape. During the colorimetric process, the rotating disk 16 is rotated to facilitate the colorimetric analysis of the drainage fluid.

[0036] Furthermore, as shown in Figures 1-4, in order to achieve better fixation and colorimetric effects, the fixing mechanism 3 is an X-shaped elastic band, and the bag body 1 and the comparison sleeve 6 are both made of transparent materials. The bag body 1 is made of medical plastic, which is transparent and can be deformed, while the comparison sleeve 6 can be made of glass.

[0037] It should be noted that bile drainage is normally golden yellow or dark green; when oxidized by gastric acid or infected by bacteria, it is grass green; when the gallbladder or bile duct is obstructed, it is white; a small amount of bleeding is light red; and a large amount of bleeding is bright red. The color comparison can be used to make a preliminary judgment of the condition.

[0038] When using this invention, the bag body 1 is first suspended and fixed by the suspension ring 2 and the fixing mechanism 3. After connecting the upper side of the bag body 1 to the patient's drainage tube, normal drainage can be performed. During the drainage process, medical staff can allow the drainage fluid to enter the corresponding storage bag 5 as needed. Then, the drainage fluid for that time period is first placed into the corresponding drainage bag. Afterward, the color of the drainage fluid in the storage bag 5 can be carefully observed and compared by the comparison sleeve 6. Through the colorimetric mechanism 4, a preliminary judgment can be made on the different colors of the drainage fluid, reducing the risk of missed diagnosis by medical staff.

[0039] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the purpose of intuitively judging the condition of the patient's drainage fluid, facilitates the differentiation of drainage fluid at different time periods, increases the smoothness of drainage, adds the function of preserving the color of drainage fluid at different time periods, enables better storage of drainage fluid, facilitates the comparison of drainage fluid colors, and achieves better fixation and colorimetric effects.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
