Description

Technical Field

[0001] The present application relates to the field of medical instruments, and in particular to an adapter assembly for a liquid collector. Background Art

[0002] A catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is mainly used by people who need to stay in bed for a long time, have limited mobility, and cannot control urine. The urine is drained through the catheter and then transported to a urine bag through an infusion tube.

[0003] The liquid collector includes a urinal, an infusion tube and a urine bag. The urinal is usually designed to be wearable so that the patient can wear it on the body. The urine is discharged into the urinal and transported to the urine bag by the infusion tube.

[0004] Since the catheter is left in the human body, it is easy to cause urinary tract infection after a long retention time. Therefore, when the patient can control urine independently, the catheter needs to be removed and a fluid collector is used to replace the indwelling catheter.

[0005] The current combination of a catheter, an infusion tube and a urine bag, as well as a combination of a urinal, an infusion tube and a urine bag are all integrated, and need to be completely replaced when replaced, which easily increases the financial burden on patients. Utility Model Content

[0008] A transfer joint assembly for a liquid collector, comprising a first joint and a second joint, wherein the first joint and the second joint are both hollow structures for allowing liquid to flow;

[0009] The first connector is used to connect to drainage tube 1, one end of the second connector is detachably connected to the first connector, and the other end is used to connect to drainage tube 2 or the liquid receiving sleeve.

[0010] By adopting the above technical solution, when using drainage tube 2, the operator connects the two ends of the second connector to drainage tube 2 and the first connector respectively; when changing to a liquid collector, the operator connects the two ends of the second connector to the liquid collecting sleeve and the first connector respectively. In this way, drainage tube 1 and a liquid collecting bag are saved, which helps to reduce the economic burden on patients. Medical staff can switch between drainage tube 2 and the liquid collector according to the actual situation of the patient to meet different needs, which is convenient and flexible.

[0011] Optionally, the first joint is threadedly connected to the second joint.

[0012] By adopting the above technical solution, the threaded connection structure is simple and the connection and disassembly are fast.

[0013] Optionally, opposite ends of the first joint and the second joint are provided with an internal thread and an external thread respectively.

[0016] By adopting the above technical solution, the plug-in connection method is simple and convenient for quick installation when in use.

[0017] Optionally, the cannula is provided with a conical surface surrounding its axis, the conical surface extends toward one end of the cannula away from the second joint, and the outer diameter of the conical surface gradually decreases, and the outer diameter of the large diameter end of the conical surface is larger than the inner diameter of the drainage tube 2.

[0018] By adopting the above technical solution, the conical surface facilitates the insertion of the cannula into the second drainage tube and has a guiding effect; the second drainage tube is clamped by the conical surface, and there is no need to add other reinforcing connection structures, the connection is convenient, and the sealing is improved.

[0019] Optionally, the conical surface is provided with a plurality of stepped surfaces which are arranged axially along the insertion tube and whose diameters gradually decrease.

[0020] By adopting the above technical solution, the stepped surface increases the friction between the conical surface and the drainage tube 2, thereby achieving an anti-slip effect.

[0021] Optionally, the second connector is integrally formed with the liquid outlet end of the liquid receiving sleeve.

[0022] By adopting the above technical solution, the sealing performance of the connection between the second joint and the liquid receiving sleeve is enhanced.

[0023] Optionally, the first joint is provided with a plurality of reinforcing ribs arranged at intervals around its axis.

[0024] By adopting the above technical solution, the reinforcing edge increases the friction between the first joint and the hand, making it easier to rotate the first joint.

[0025] Optionally, the first joint includes a first pipe segment and a second pipe segment that are connected, and an outer diameter of the second pipe segment is smaller than an outer diameter of the first pipe segment.

[0026] By adopting the above technical solution, the first joint has a simple composition and is convenient for quick connection.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Through the first joint and the second joint, the drainage tube 1 and the liquid collecting bag can be switched between the drainage tube 2 and the liquid collecting sleeve, without the need to replace the drainage tube 2 and the liquid collecting bag as a whole, thus saving resource waste and reducing the economic burden on patients;

"First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention. Example 1

[0039] like Figure 1 The embodiment of the present application discloses an adapter assembly for a liquid collector, including a first connector 1 and a second connector 2. The first connector 1 and the second connector 2 are both hollow structures for allowing liquid to flow.

[0040] The first connector 1 is used to connect with the drainage tube 1 42 , one end of the second connector 2 is detachably connected with the first connector 1 , and the other end is used to connect with the drainage tube 2 3 or the liquid receiving sleeve 41 .

[0041] like Figure 2 and Figure 3 The first joint 1 is threadedly connected to the second joint 2. The inner circumference of the first joint 1 is provided with an internal thread, and the outer circumference of the second joint 2 is provided with an external thread matching the internal thread. The length of the internal thread is less than the length of the external thread.

[0042] In some embodiments, the first joint 1 can be configured as an external thread, and the second joint 2 can be configured as an internal thread. The first joint 1 is threadedly connected to the second joint 2, and the thread forms can be freely combined.

[0043] like Figure 2 The first joint 1 is provided with a plurality of reinforcing edges 13 arranged at intervals around its axis. The reinforcing edges 13 are used to increase the friction force when the medical staff twists the first joint 1, thereby enhancing the hand feel.

[0044] The first joint 1 includes a first pipe section 11 and a second pipe section 12 that are connected. The outer diameter of the second pipe section 12 is smaller than the outer diameter of the first pipe section 11. The internal thread is arranged in the first pipe section 11. The reinforcing rib 13 is arranged on the outer circumferential wall of the first pipe section 11. The second pipe section 12 is a straight pipe for being inserted into the drainage tube 1 42. The first pipe section 11, the second pipe section 12 and the reinforcing rib 13 are integrally formed. In order to ensure the sealing between the second pipe section 12 and the drainage tube 1 42, glue can be applied to the outer wall of the first joint 1 for bonding.

[0045] One end of the first pipe section 11 away from the second pipe section 12 is provided with a circle of radially extending first edge 14 to increase the overall strength of the first joint 1 .

[0046] like Figure 3 The second connector 2 is provided with an insert tube 21 extending from one end away from the first connector 1. The insert tube 21 is integrally formed with the second connector 2. The insert tube 21 is plugged into the drainage tube 2 3. Preferably, the insert tube 21 is plugged into the drainage tube 2 3. The insert tube 21 is provided with a conical surface 22 surrounding its axis. The conical surface 22 extends toward the end of the insert tube 21 away from the second connector 2, and the outer diameter of the conical surface 22 gradually decreases. The outer diameter of the large diameter end of the conical surface 22 is greater than the inner diameter of the drainage tube 2 3.

[0047] The conical surface 22 is provided with a plurality of stepped surfaces 23 which are arranged along the axial direction of the inserting tube 21 and whose diameters gradually decrease. The stepped surfaces 23 surround the inserting tube 21 and are cylindrical surfaces.

[0048] One end of the insert tube 21 close to the second joint 2 is provided with a second edge 24 extending radially.

[0049] like Figure 5 When connecting the drainage tube 23, the cannula 21 is inserted into the drainage tube 23. The drainage tube 23 has a certain elasticity. As the outer diameter of the conical surface 22 gradually increases, the drainage tube 23 and the conical surface 22 are tightly connected. When the drainage tube 23 is large, the drainage tube 23 can be pulled over the second extended edge 24, so that the drainage tube 23 wraps the second extended edge, thereby achieving the effect of strengthening the connection.

[0050] When using drainage tube 2 3 , the first joint 1 is threadedly connected with the second joint 2 and tightened, and the end of the first joint 1 away from the second joint 2 is plugged into the drainage tube 1 42 , and the insertion tube 21 is plugged into the drainage tube 2 3 . Example 2

[0051] like Figure 4 and Figure 6 , an adapter for a liquid collector and a drainage tube 2 3 , which is different from Example 1 in that the second connector 2 and the liquid outlet end of the liquid receiving sleeve 41 are integrally formed.

[0052] When the liquid collector is used, the first joint 1 is threadedly connected with the second joint 2 and tightened and fixed, and the end of the first joint 1 away from the second joint 2 is plugged into the drainage tube 1 42 .

[0053] When the drainage tube 2 3 is switched to the liquid collector, the first connector 1 is twisted to separate from the second connector 2 corresponding to the cannula 21 , and the first connector 1 is screwed onto the second connector 2 corresponding to the liquid outlet end of the liquid receiving sleeve 41 .

[0054] The principle of the embodiment of the present application: the drainage tube 1 42 and the liquid collecting bag 43 are of an integrated design, and the drainage tube 1 42 is connected and switched between the drainage tube 2 3 and the liquid collecting sleeve 41 through the first connector 1 and the second connector 2. Compared with the integrated drainage tube 2 3 and the liquid collector, the drainage tube 1 42 and the liquid collecting bag 43 resources are saved, so that the economic burden of the patient is reduced.

[0055] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
