DETAILED DESCRIPTION
[0024] 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.
[0025] See also Figure 1-6 The utility model provides a technical solution: a drainage bag with adjustable drainage tube length, comprising a drainage bag 1 for storing urine, a drainage tube 2 with one end connected thereto being provided at one end of the drainage bag 1, a buckle switch 4 for controlling whether the switch of the drainage tube 2 can drain urine into the drainage bag 1 being sleeved on the drainage tube 2, a clamping hole 42 being provided on the clamping switch 4, the drainage tube 2 passing through the clamping hole 42 so that the buckle switch 4 is sleeved on the drainage tube 2, and the clamping hole 42 is conical, when the drainage tube 2 is in an open state, the drainage tube 2 is located at the upper end of the conical clamping hole 42, when the drainage tube 2 needs to be closed, the drainage tube 2 is clamped into the lower end of the clamping hole 42 along the upper end of the clamping hole 42 to close the drainage tube 2, thereby preventing urine from being drained into the drainage bag 1.
[0026] The snap switch 4 is also provided with two elastic blocks 40 fixedly connected thereto. The elastic blocks 40 are mirror-imaged on the left and right sides of one end of the snap switch 4 to form a receiving slot 41 for winding and storing the drainage tube 2. The elastic blocks 40 are in a 7-shape. An embedding opening 43 for embedding the drainage tube 2 in the receiving slot 41 for storage is also provided between the elastic blocks 40. The embedding opening 43 is connected to the receiving slot 41. By providing the elastic blocks 40 mirror-imaged on the left and right sides of one end of the snap switch 4, a receiving slot 41 is formed between the two 7-shaped elastic blocks 40. When the patient does not need to urinate, if the drainage tube 2 is too long, it will affect some of the patient's behaviors. Since the elastic block 40 is made of elastic medium and has a certain elastic function, the drainage tube 2 can be rolled up and then the entire roll of the wound drainage tube 2 can be squeezed from the embedding opening 43 into the receiving slot 41 for storage. In this way, it can be avoided that the drainage tube 2 is too long when not urinating, thereby affecting some of the patient's daily behaviors.
[0027] A connector 20 is fixedly connected to the other end of the drainage tube 2. The connector 20 is used to be fixedly connected to the patient's urinary catheter. Only by fixing the connector 20 to the patient's urinary catheter can the patient drain urine through the urinary catheter to the drainage tube 2 and then into the drainage bag 1 when urinating. The diameter of the largest end face of the connector 20 is larger than the diameter of the largest end of the clamping hole 42, so that the buckle switch 4 can be prevented from falling off the drainage tube 2.
[0028] The other end of the drainage bag 1 is also provided with a drainage device 3 for discharging urine in the drainage bag 1. The drainage device 3 includes a connecting tube 30 connected to the drainage bag 1 at one end, a drainage tube 31 connected to the other end of the connecting tube 30, and a limiting cover 32 that is limited and matched with the drainage tube 31 and is used to control the switch of the drainage tube 31. The limiting cover 32 is in the shape of a hollow truncated cone. A limiting column 321 fixedly connected to the limiting cover 32 is provided at the end of the limiting cover 32 away from the drainage bag 1. When one end of the drainage tube 31 is inserted into the limiting cover 32 for locking and matching, the limiting column 32 1 will be embedded in the drain pipe 31 and cooperate with it to block the drain pipe 31, so as to ensure the sealing performance of the limiting column 321 on the drain pipe 31 and prevent the limiting cover 32 from falling suddenly and causing the limiting column 321 to slip out of the drain pipe 31, a clamping block 310 fixedly connected to it is provided on the outer wall of the drain pipe 31, a clamping groove 320 is provided on the inner wall of the limiting cover 32, and an embedding groove 322 is also provided on the inner wall of the limiting cover 32, and one end of the embedding groove 322 is vertically connected to the clamping groove 320. The other end of the embedding groove 322 extends to the entrance end of the limiting cover 32. When the drain pipe 31 needs to be embedded in the limiting cover 32 so that the limiting column 321 blocks the drain pipe 31, the positioning block 310 on the outer wall of the drain pipe 31 is aligned with the embedding groove 322, so that the positioning block 310 slides along the embedding groove 322 during the process of the drain pipe 31 being embedded in the limiting cover 32, until the positioning block 310 slides to the connection between the embedding groove 322 and the positioning groove 320, and the drain pipe 31 is rotated along the length direction of the positioning groove 320. 1 or rotate the limiting cover 32 in the opposite direction along the length of the locking groove 320, so that the locking block 310 and the locking groove 320 can be locked and matched. After the discharge pipe 31 is embedded in the limiting cover 32, the limiting column 321 in the limiting cover 32 is embedded in the drainage pipe 2 to limit and match it to seal it. At this time, the locking block 310 and the locking groove 320 are combined to prevent the limiting cover 32 from loosening, resulting in the limiting column 321 failing to completely block the discharge pipe 31, thereby preventing the urine in the drainage bag 1 from leaking out.
[0029] Because the limiting cover 32 is in the shape of a hollow truncated cone and the limiting column 321 is in the shape of a cylinder, the distance between the inner wall of the limiting cover 32 and the outer wall of the limiting column 321 will gradually decrease along the end away from the drainage bag 1. In this way, when the locking block 310 and the locking groove 320 are locked together, the tube wall of the drainage tube 31 is located between the limiting cover 32 and the limiting column 321. In this way, by making the distance between the inner wall of the limiting cover 32 and the outer wall of the limiting column 321 gradually decrease along the end away from the drainage bag 1, the stability of the locking between the locking block 310 and the locking groove 320 can be fully guaranteed, thereby further avoiding the limiting cover 32 from suddenly loosening, resulting in the drainage tube 31 failing to be completely blocked and causing urine leakage.
[0030] The outer wall of the drain pipe 31 is also provided with a locking convex ring 311 fixedly connected thereto, and the inner wall of the limiting cover 32 is also provided with a locking ring 323 fixedly connected thereto. In this way, when the drain pipe 31 is inserted into the limiting cover 32, abutment and sliding will occur between the locking convex ring 311 and the locking ring 323. By providing the locking convex ring 311 on the outer wall of the drain pipe 31, after the drain pipe 31 is inserted into the limiting cover 32, due to the setting of the locking convex ring 311, the drain pipe 31 can be tightly clamped between the inner wall of the limiting cover 32 and the outer wall of the limiting column 321. Moreover, due to the setting of the locking ring 323 on the inner wall of the limiting cover 32, the locking ring 323 will also limit the outer wall of the drain pipe 31 in a full circle, thereby achieving the stability of the limiting cooperation between the drain pipe 31 and the limiting cover 32.
[0031] The working principle of the utility model is as follows: by providing the elastic card block 40 with a left and right mirror image arrangement on the buckle switch 4, when the patient does not need to urinate, the drainage tube 2 can be rolled up and then the wound drainage tube 2 can be squeezed from the embedding opening 43 into the storage card slot 41 for storage, so that the drainage tube 2 can be prevented from being too long and affecting some of the patient's daily behaviors when not urinating;
[0032] When the drain pipe 31 needs to be embedded in the limiting cover 32 so that the limiting column 321 can block the drain pipe 31, the blocking block 310 on the outer wall of the drain pipe 31 is aligned with the embedding groove 322, so that the drain pipe 31 is embedded in the limiting cover 32. The blocking block 310 slides along the embedding groove 322 until the blocking block 310 slides to the connection between the embedding groove 322 and the blocking groove 320. At this time, the drain pipe 31 is rotated along the length direction of the blocking groove 320 or the limiting cover 32 is rotated in the opposite direction of the length of the blocking groove 320, so that the blocking block 310 and the blocking groove 320 can be engaged with each other. The limiting column 321 in the cover 32 is embedded in the drainage tube 2 and cooperates with it to seal it tightly. At this time, due to the locking cooperation between the locking block 310 and the locking groove 320, medical staff can clearly judge that the drainage tube 31 is in a blocked and closed state when using a drainage bag with an adjustable drainage tube length. This can avoid the limiting column 321 failing to completely block the drainage tube 31, or the limiting cover 32 suddenly loosens, resulting in the limiting column 321 failing to completely block the drainage tube 31, thereby causing urine in the drainage bag 1 to leak out and cause cleanliness problems, thereby improving the stability and security of the drainage bag with an adjustable drainage tube length.
