Description

Technical Field

[0001] This utility model relates to the field of hepatobiliary drainage technology, and in particular to a drainage tube connector. Background Technology

[0002] Hepatobiliary drainage is a medical procedure that involves placing a drainage tube in the liver or biliary system to drain bile or other fluids (such as infectious exudate, blood, etc.) out of the body or to other parts of the body (such as the intestines) to treat diseases, relieve symptoms, and promote recovery. A drainage tube connector is a component used to connect the drainage tube to the drainage bag, designed to ensure the safe and smooth transfer of liquids or gases during the drainage process.

[0003] Staff often find that the current drainage tube and drainage bag are usually connected by a rubber tube and a plastic connector. However, in clinical practice, the drainage tube and drainage bag are often loosely fitted and separate. To prevent this, nurses usually use adhesive tape to wrap around the connection between the drainage tube and drainage bag after inserting the drainage bag into the drainage tube to prevent separation. However, when changing the drainage bag, the adhesive tape must be removed, which is cumbersome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drainage tube connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drainage tube connector, comprising a connector body, a drainage bag connector, a drainage tube body, and a connecting structure, the connecting structure mainly consisting of two connectors, which are respectively fixedly connected to the drainage bag connector and the drainage tube body. A second magnetic block is fixedly connected to both the drainage bag connector and the drainage tube body. A first magnetic block is fixedly connected to both ends of the connector body. The two surfaces of the first magnetic block and the corresponding second magnetic block that are in contact are opposite poles. Two locking rods are slidably inserted into the connector body, and locking grooves are formed on the connector heads.

[0006] The effect achieved by the above components is as follows: when the two connectors are inserted into the two ends of the connector body, the first and second magnetic blocks will attract each other under the action of magnetic force, which can quickly connect the drainage bag connector and the drainage tube body together. Then, the locking rod is slid to lock it into the locking groove, which can limit the connector and prevent the patient from accidentally pulling it off. This avoids the situation where nursing staff usually insert the drainage bag into the drainage tube and use adhesive tape to wrap the connection between the drainage tube and the drainage bag to prevent the drainage tube and the drainage bag from separating. However, when the drainage bag is replaced next time, the adhesive tape needs to be removed before replacement, which leads to a cumbersome operation.

[0007] Preferably, a sealing ring is fixedly connected to the connector head, and two sealing grooves are formed on the inner wall of the connector body.

[0008] The effect achieved by the above components is as follows: the sealing ring is made of rubber, and when the sealing ring is inserted into the corresponding sealing groove, the sealing performance of the connection can be improved and leakage can be prevented.

[0009] Preferably, the inner wall of the connector body is provided with three circular grooves, a telescopic column is fixedly connected in the circular grooves, a ball is fixedly connected to one end of the telescopic column, the connector head is provided with three limiting grooves, a first spring is sleeved on the telescopic column, one end of the first spring is fixedly connected to the ball, and the other end of the first spring is fixedly connected to the inner wall of the circular groove.

[0010] The effect achieved by the above components is as follows: when the connector is inserted into the connector body, the three limiting grooves will push the smooth surface of the ball, causing it to retract into the groove. At this time, the first spring is in a contracted state. Therefore, when the ball comes into contact with the limiting groove, the ball will be stuck into the limiting groove under the action of the spring rebound force, making the connection more stable.

[0011] Preferably, a second spring is sleeved on the locking rod, one end of the second spring is fixedly connected to the locking rod, and the other end of the second spring is fixedly connected to the connector body.

[0012] The effect achieved by the above components is that when the locking rod is inserted into the locking slot, the second spring is in a stretched state, so the rebound force of the second spring acts on the locking rod, making the limiting more stable.

[0013] Preferably, the connector body is provided with an anti-backflow structure, which mainly consists of a fixing block. The fixing block is fixedly connected to the connector body, and a sliding rod is slidably inserted on the fixing block. One end of the sliding rod is fixedly connected to a baffle, and a fixing ring is fixedly connected to the connector body.

[0014] The effect achieved by the above components is that when the liquid flows in the forward direction, the baffle moves away from the fixed ring, and when it flows in the reverse direction, the baffle covers the fixed ring, which can prevent backflow from causing harm to the patient.

[0015] Preferably, a conical block is fixedly connected to the baffle, and a rubber ring is fixedly connected to the conical block.

[0016] The effect achieved by the above components is that the conical block is inserted into the fixing ring, and the rubber ring can improve the sealing performance, thereby improving the backflow prevention effect.

[0017] Preferably, a third spring is sleeved on the slide rod, one end of the third spring is fixedly connected to the baffle, and the other end of the third spring is fixedly connected to the fixing block.

[0018] The effect achieved by the above components is as follows: when liquid flows from the direction of the drainage bag connector to the direction of the drainage tube body, it will push the baffle to insert the anti-backflow structure into the fixing ring. At this time, the third spring is in a stretched state. Therefore, when the anti-backflow pushing force disappears, the baffle will rebound and reset under the action of the rebound force of the third spring to prevent affecting the forward flow and make the operation more convenient.

[0019] Preferably, an indicator arrow is fixedly connected to the connector body.

[0020] The effect achieved by the above-mentioned components is that the indicator arrow points in the direction of liquid flow to remind workers and prevent the connector body from being installed backwards.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a connection structure, two connectors are inserted into the two ends of the connector body respectively. At this time, the first magnetic block and the second magnetic block are attracted together under the action of magnetic force, which can quickly connect the drainage bag connector and the drainage tube body together. Then, the sliding locking rod is used to lock it into the locking groove, which can limit the connector and prevent the patient from accidentally pulling it off. This avoids the situation where nursing staff usually insert the drainage bag into the drainage tube and use adhesive tape to wrap the connection between the drainage tube and the drainage bag to prevent the drainage tube and the drainage bag from separating. However, when the drainage bag is replaced next time, the adhesive tape needs to be removed before replacement, which leads to a cumbersome operation. Attached Figure Description

[0027] Example 1, as Figure 1 As shown, a drainage tube connector includes a connector body 1, a drainage bag connector 2 disposed on the connector body 1, and a drainage tube body 3 disposed on the connector body 1.

[0028] Reference Figure 2 and Figure 3The connector body 1 is provided with a connecting structure 4, which mainly consists of two connectors 41. The two connectors 41 are fixedly connected to the drainage bag connector 2 and the drainage tube body 3, respectively. A second magnetic block 43 is fixedly connected to both the drainage bag connector 2 and the drainage tube body 3. A first magnetic block 42 is fixedly connected to both ends of the connector body 1. The two surfaces of the first magnetic block 42 and the corresponding second magnetic block 43 that are in contact are opposite poles. Two locking rods 411 are slidably inserted into the connector body 1. The connectors 41 are provided with locking grooves 412. When the two connectors 41 are inserted into the two ends of the connector body 1, the first magnetic block 42 and the second magnetic block 43 are then... Under magnetic attraction, the drainage bag connector 2 and the drainage tube body 3 can be quickly connected together. Then, the sliding locking rod 411 is used to lock it into the locking groove 412, which limits the connection head 41 and prevents the patient from accidentally pulling it off. This avoids the cumbersome operation that nurses usually use after inserting the drainage bag into the drainage tube and wrapping adhesive tape around the connection between the drainage tube and the drainage bag to prevent separation. However, when changing the drainage bag, the adhesive tape must be removed before replacement. The connection head 41 is fixedly connected with a sealing ring 44, and the inner wall of the connector body 1 is provided with a sealing ring 44. Two sealing grooves 45 and a rubber sealing ring 44 are provided. Inserting the sealing ring 44 into the corresponding sealing groove 45 improves the sealing performance and prevents leakage. Three circular grooves 46 are formed on the inner wall of the connector body 1. A telescopic post 47 is fixedly connected to each groove 46, and a ball 48 is fixedly connected to one end of each telescopic post 47. Three limiting grooves 49 are formed on the connector head 41. A first spring 410 is fitted onto the telescopic post 47, with one end fixedly connected to the ball 48 and the other end fixedly connected to the inner wall of the circular groove 46. When the connector head 41 is inserted into the connector body 1, the three limiting grooves 49 push the ball 48. The smooth surface of the ball 48 causes it to retract into the circular groove 46. At this time, the first spring 410 is in a contracted state. Therefore, when the ball 48 contacts the limiting groove 49, the ball 48 is locked into the limiting groove 49 under the action of the rebound force of the first spring 410, making the connection more stable. The locking rod 411 is fitted with a second spring 413. One end of the second spring 413 is fixedly connected to the locking rod 411, and the other end of the second spring 413 is fixedly connected to the connector body 1. When the locking rod 411 is inserted into the locking groove 412, the second spring 413 is in a stretched state. Therefore, the rebound force of the second spring 413 acts on the locking rod 411, making the limiting more stable.

[0029] Reference Figure 1 and Figure 4The connector body 1 is equipped with an anti-backflow structure 5, which mainly consists of a fixing block 51. The fixing block 51 is fixedly connected to the connector body 1. A sliding rod 52 is slidably inserted into the fixing block 51. A baffle 53 is fixedly connected to one end of the sliding rod 52. A fixing ring 54 is fixedly connected to the connector body 1. When the liquid flows in the forward direction, the baffle 53 moves away from the fixing ring 54. When the liquid flows in the reverse direction, the baffle 53 covers the fixing ring 54, which can prevent backflow from causing harm to the patient. A conical block 55 is fixedly connected to the baffle 53. A rubber ring 56 is fixedly connected to the conical block 55. The conical block 55 is inserted into the fixing ring 54. The rubber ring 56 can improve the sealing performance, thereby improving the anti-backflow effect. A third spring 57 is fitted on the connector 2. One end of the third spring 57 is fixedly connected to the baffle 53, and the other end of the third spring 57 is fixedly connected to the fixing block 51. When liquid flows from the direction of the drainage bag connector 2 to the direction of the drainage tube body 3, it will push the baffle 53 to insert the anti-backflow structure 5 into the fixing ring 54. At this time, the third spring 57 is in a stretched state. Therefore, when the anti-backflow pushing force disappears, the baffle 53 will rebound and reset under the action of the rebound force of the third spring 57 to prevent affecting the forward flow and make the operation more convenient. An indicator arrow 58 is fixedly connected to the connector body 1. The direction of the indicator arrow 58 is the direction of liquid flow to remind the staff and prevent the connector body 1 from being installed backwards.

[0030] Working principle: When the two connectors 41 are inserted into the two ends of the connector body 1, the first magnet 42 and the second magnet 43 are attracted together by magnetic force, which can quickly connect the drainage bag connector 2 and the drainage tube body 3. Then, the locking rod 411 is slid to lock into the locking groove 412, which can limit the connector 41 and prevent the patient from accidentally pulling it off. This avoids the common practice of nursing staff using adhesive tape to wrap around the connection between the drainage tube and the drainage bag after inserting the drainage bag, which can prevent this. The drainage tube and drainage bag are separate, but the adhesive tape needs to be removed before the drainage bag can be replaced, which is cumbersome. The sealing ring 44 is made of rubber. Inserting the sealing ring 44 into the corresponding sealing groove 45 can improve the sealing of the connection and prevent leakage. When the connector 41 is inserted into the connector body 1, the three limiting grooves 49 will push the smooth surface of the ball 48, causing it to retract into the groove 46. At this time, the first spring 410 is in the contracted state. Therefore, when the ball 48 contacts the limiting groove 49, The ball 48 is engaged in the limiting groove 49 by the rebound force of the first spring 410, making the connection more stable. When the locking rod 411 is inserted into the locking groove 412, the second spring 413 is in a stretched state. Therefore, the rebound force of the second spring 413 acts on the locking rod 411, making the limiting more stable. When the liquid flows in the forward direction, the baffle 53 moves away from the fixing ring 54. When it flows in the reverse direction, the baffle 53 covers the fixing ring 54 to prevent backflow from causing harm to the patient. The conical block 55 is inserted into the fixing ring 54, and the rubber ring 56 can... Improving the sealing performance enhances the anti-backflow effect. When liquid flows from the direction of the drainage bag connector 2 to the direction of the drainage tube body 3, it pushes the baffle 53, causing the anti-backflow structure 5 to insert into the fixing ring 54. At this time, the third spring 57 is in a stretched state. Therefore, when the anti-backflow pushing force disappears, the baffle 53 will rebound and reset under the action of the rebound force of the third spring 57, preventing it from affecting the forward flow and making the operation more convenient. The direction of the indicator arrow 58 is the direction of liquid flow to remind the staff and prevent the connector body 1 from being installed backwards.
