Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a gastrointestinal fluid decompression device for gastrointestinal surgery. Background Technology

[0002] Gastrointestinal decompression utilizes negative pressure suction to remove accumulated contents and gas from the gastrointestinal tract, thereby reducing intra-intestinal pressure. For patients with intestinal obstruction, gastrointestinal decompression can reduce intra-intestinal pressure and improve blood circulation in the intestinal wall; for those with gastrointestinal perforation, it can prevent further leakage of digestive juices into the abdominal cavity; for post-operative patients, it can promote the healing of gastrointestinal anastomoses; for preoperative patients, it can eliminate gastrointestinal distension, facilitating intra-abdominal surgical procedures, and postoperatively, it promotes the recovery of gastrointestinal motility.

[0003] When using existing gastrointestinal fluid decompression devices for gastrointestinal surgery, if the drainage bottle is full and not emptied in time, the gastrointestinal fluid can easily flow back to the central negative pressure, causing contamination and damage to the central negative pressure. In addition, existing gastrointestinal fluid decompression devices for gastrointestinal surgery have only one suction port, located at the end of the suction tube, which results in a small suction range and poor suction effect. Utility Model Content

[0004] The purpose of this invention is to provide a gastrointestinal fluid decompression device for gastrointestinal surgery to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A gastrointestinal fluid decompression device for gastrointestinal surgery includes a collection bottle. The top of the collection bottle is connected to a detachable sealing cap. A handle is provided on the upper surface of the sealing cap. A connector and an anti-backflow valve are respectively provided on both sides of the upper surface of the sealing cap. A negative pressure tube is connected to the connector. A suction tube is connected to the anti-backflow valve. A round head is provided at the end of the suction tube. Multiple suction holes arranged in a circumferential array are provided on the surface of the round head and the side wall of the end of the suction tube. A convex plate is provided in the middle of the bottom of the sealing cap. Side plates are provided on both sides of the bottom of the convex plate located on the negative pressure tube. A float that can move up and down is provided between the two side plates.

[0006] Preferably, the surface of the collection bottle is provided with an observation window, and the observation window is provided with scale lines.

[0007] Preferably, the upper surface of the collection bottle is provided with an annular sealing groove along its path direction, and the bottom of the sealing cap is provided with a sealing ring corresponding to the sealing groove at the periphery of the convex plate, and the size of the sealing ring matches the size of the sealing groove.

[0008] Preferably, the diameter of the convex plate matches the inner diameter of the bottle opening.

[0009] Preferably, the top sidewall of the collection bottle is provided with four fixing blocks arranged in a circumferential array. The upper surface of the fixing block is provided with an insertion port, and the sidewall of the fixing block is provided with a through hole communicating with the insertion port. The sidewall of the sealing cap is provided with four insertion blocks that correspond one-to-one with the insertion port. The size of the insertion block matches the size of the insertion port, and the sidewall of the insertion block is provided with threaded holes that correspond to the through holes. The threaded holes and the through holes are fixedly connected by screws.

[0010] Preferably, the outlet end of the negative pressure pipe extends below the convex plate and is located between the two side plates.

[0011] Preferably, each of the two side plates has a vertically distributed trapezoidal groove on one side, the bottom of the trapezoidal groove is a closed structure, both ends of the float are provided with trapezoidal blocks that slide vertically and vertically connected to the trapezoidal groove, and the middle part of the upper surface of the float is provided with a groove, the diameter of the groove being greater than or equal to the outer diameter of the negative pressure pipe outlet end.

[0012] The gastrointestinal fluid decompression device for gastrointestinal surgery of this invention has the following advantages:

[0013] 1. This utility model greatly increases the suction range of gastrointestinal fluid by setting multiple suction holes on the end side wall of the suction tube, thereby improving the suction effect of gastrointestinal fluid, making it more efficient and practical.

[0014] 2. This utility model, through the cooperation between the sealing ring and the sealing groove, seals the connection between the sealing cap and the collection bottle when the sealing cap is placed on the collection bottle, achieving a good sealing effect. Furthermore, through the cooperation between the insert block and the fixing block, the sealing cap is limited, resulting in a good fixing effect and effectively preventing the sealing cap from being accidentally opened, thus ensuring good safety.

[0015] 3. The trapezoidal block and the trapezoidal groove cooperate to facilitate the movement of the float between the two side plates, while also limiting the float's position. Initially, under the influence of its own weight, the float will be at the bottom between the two side plates. When gastrointestinal fluid is drawn into the collection bottle, the liquid level in the collection bottle will gradually rise. When the liquid level contacts the bottom of the float, the rising liquid level will cause the float to rise gradually. When the groove of the float contacts the outlet end of the negative pressure tube, it will seal the opening of the negative pressure tube. At this time, the negative pressure inside the collection bottle will disappear, and the suction will passively stop, preventing gastrointestinal fluid from entering the negative pressure tube, avoiding contamination and damage to the central negative pressure, and maintaining the cleanliness of the ward floor and the environment.

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a gastrointestinal fluid decompression device for gastrointestinal surgery.

[0029] like Figure 1-5As shown, this utility model discloses a gastrointestinal fluid decompression device for gastrointestinal surgery, comprising a collection bottle 1. The surface of the collection bottle 1 is provided with an observation window 3, which has graduated lines. The observation window 3 and the graduated lines facilitate observation of the amount of gastrointestinal fluid collected in the collection bottle 1. A detachable sealing cap 2 is connected to the top of the collection bottle 1. A handle 4 is provided on the upper surface of the sealing cap 2. An annular sealing groove 13 is provided on the upper surface of the collection bottle 1 along its path direction. A sealing ring 17, corresponding to the sealing groove 13, is provided at the bottom of the sealing cap 2, around the periphery of a protruding plate 18. The size of the sealing ring 17 matches the size of the sealing groove 13. Through the cooperation between the sealing ring 17 and the sealing groove 13, when the sealing cap 2 is placed on the collection bottle 1, the connection between the sealing cap 2 and the collection bottle 1 is sealed, providing a good sealing effect. The diameter of the protruding plate 18 matches the inner diameter of the bottle opening of the collection bottle 1, allowing the protruding plate 18 to be positioned inside the bottle opening of the collection bottle 1. The outlet end of the negative pressure tube 7 extends below the convex plate 18 and is located between the two side plates 11. The top side wall of the collection bottle 1 is provided with four fixing blocks 14 arranged in a circumferential array. The upper surface of each fixing block 14 is provided with an insertion port 15. The side wall of each fixing block 14 is provided with a through hole 16 communicating with the insertion port 15. The side wall of the sealing cap 2 is provided with four insertion blocks 19 corresponding to the insertion ports 15. The size of each insertion block 19 matches the size of the insertion port 15, and the side wall of each insertion block 19 is provided with… The threaded holes 20 are distributed corresponding to the through holes 16. The threaded holes 20 and the through holes 16 are fixedly connected by screws. When the sealing cap 2 is placed on the collection bottle 1, the four inserts 19 are aligned with the four inserts 15 and inserted into them. At this time, the sealing cap 2 will be limited. Then, the screws are screwed into the threaded holes 20 through the through holes 16 to lock and fix the sealing cap 2. This makes the sealing cap 2 well fixed and can effectively prevent the sealing cap 2 from being opened by mistake, thus ensuring good safety.

[0030] The upper surface of the sealing cap 2 is provided with a connector 5 and an anti-backflow valve 6 on both sides. A negative pressure tube 7 is connected to the connector 5, and a suction tube 8 is connected to the anti-backflow valve 6. The end of the suction tube 8 is provided with a round head 9. The surface of the round head 9 and the side wall of the end of the suction tube 8 are provided with multiple suction holes 10 arranged in a circumferential array. By providing multiple suction holes 10 on the side wall of the end of the suction tube 8, the suction range of gastrointestinal fluid is greatly increased, thereby improving the suction effect of gastrointestinal fluid, making it more efficient and practical. A convex plate 18 is provided in the middle of the bottom of the sealing cap 2. The bottom of the convex plate 18 is provided with side plates 11 on both sides of the negative pressure tube 7. A float 12 that can move up and down is provided between the two side plates 11. Each of the two side plates 11 has vertically distributed trapezoidal grooves 21 on one side. The bottom of the trapezoidal grooves 21 is a closed structure. Both ends of the float 12 are provided with trapezoidal blocks 22 that slide vertically and vertically with the trapezoidal grooves 21. A groove 23 is provided in the middle of the upper surface of the float 12. The diameter of the groove 23 is greater than or equal to the outer diameter of the outlet end of the negative pressure pipe 7. Through the cooperation between the trapezoidal blocks 22 and the trapezoidal grooves 21, the float 12 can move vertically between the two side plates 11, and at the same time, it plays a limiting role in the movement of the float 12. In the initial state, under the action of the float 12's own weight, the float... The float 12 is located at the bottom between the two side plates 11. When gastrointestinal fluid is drawn into the collection bottle 1, the liquid level in the collection bottle 1 will gradually rise. When the liquid level contacts the bottom of the float 12, the liquid level will gradually rise, causing the float 12 to gradually rise. When the groove 23 of the float 12 contacts the outlet end of the negative pressure tube 7, it will seal the opening of the negative pressure tube 7. At this time, the negative pressure inside the collection bottle 1 will disappear, and the suction work will be passively stopped to prevent gastrointestinal fluid from entering the negative pressure tube 7, avoid contamination and damage to the central negative pressure, and at the same time maintain the cleanliness of the ward floor and the tidiness of the environment.

[0031] The working principle of this gastrointestinal fluid decompression device for gastrointestinal surgery is as follows: When in use, the negative pressure tube 7 is connected to the central negative pressure device, and the end of the suction tube 8 is inserted into the gastric tube in the patient's stomach. The negative pressure device is activated to suction the gastrointestinal fluid, allowing the gastrointestinal fluid to enter the collection bottle 1 through the suction tube 8. When the gastrointestinal fluid is suctioned into the collection bottle 1, the liquid level in the collection bottle 1 will gradually rise. When the liquid level contacts the bottom of the float 12, the liquid level will gradually rise, causing the float 12 to gradually rise. When the groove 23 of the float 12 contacts the outlet end of the negative pressure tube 7, it will seal the opening of the negative pressure tube 7. At this time, the negative pressure inside the collection bottle 1 disappears, and the suction work will be passively stopped.

[0032] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
