Description

Technical Field

[0001] This application relates to the field of ureteral catheters, and particularly to a single-J ureteral stent Background Art

[0002] For patients with abnormal kidney function and difficulty in normal urination, it is usually necessary to insert a ureteral catheter from the patient's bladder into the patient's ureter to facilitate the timely discharge of urine produced by the patient's metabolism into a urine bag to ensure the patient's health

[0003] In the existing related technologies, the ureteral catheter is generally selected as a single-J ureteral stent. The single-J ureteral stent includes a catheter and a connection joint. One end of the catheter is curled, and the connection joint is detachably installed at the other end of the catheter. When using the ureteral catheter, the curled end is arranged inside the patient's body, and a urine drainage hose connected to the urine bag is directly fixedly inserted inside the connection joint to facilitate the discharge of the patient's urine into the urine bag

[0004] In view of the above related technologies, the urine drainage hose is connected to the catheter through the connection joint, and the urine drainage hose is directly fixedly inserted into the connection joint, so that urine is likely to leak between the catheter and the urine drainage hose, which is not conducive to hygiene Summary of the Invention

[0005] In order to reduce the occurrence of urine leakage between the catheter and the urine drainage hose, so as to ensure hygiene, this application provides a single-J ureteral stent

[0006] A single-J ureteral stent provided by this application adopts the following technical solutions

[0007] A single-J ureteral stent includes a partition ring and a connection tube body. The partition ring is fixedly sleeved on the outer peripheral surface of the connection tube body. The connection tube body includes a first connection part and a second connection part. The partition ring is located between the first connection part and the second connection part. A first connection cavity is penetrated and opened inside the first connection part. The outer diameter dimension of the first connection cavity is larger than the inner diameter dimension of the connection joint. A second connection cavity is penetrated and opened inside the second connection part. The first connection cavity is communicated with the second connection cavity. The inner diameter dimension of the second connection cavity is smaller than the outer diameter dimension of the catheter, and both the first connection part and the second connection part have elasticity

[0008] By adopting the above technical solution, when using the ureteral catheter, first insert the first connecting portion into the connecting joint, and make the outer peripheral surface of the first connecting portion tightly fit against the inner wall of the connecting joint. Then insert the catheter into the second connecting cavity, and make the outer peripheral surface of the catheter tightly fit against the inner wall of the second connecting cavity. Finally, fixedly plug and fit the urine drainage hose to the first connecting portion, and make the inner wall and the outer peripheral surface of the urine drainage hose tightly fit against the outer peripheral surface of the first connecting portion and the inner wall of the connecting joint respectively, thereby making it difficult for urine to leak between the catheter and the urine drainage hose, thus ensuring hygiene.

[0009] Optionally, one end of the first connecting portion away from the separating ring is provided with a contraction setting.

[0010] By adopting the above technical solution, when fixedly plugging and fitting the urine drainage hose to the first connecting portion, the contraction-set end of the first connecting portion facilitates medical staff to quickly and accurately plug and fit the urine drainage hose to the first connecting portion, reducing the occurrence of the situation where the urine drainage hose abuts against the first connecting portion and bends.

[0011] Optionally, a slope is provided on one side of the separating ring close to the first connecting portion, and the slope is inclined in a direction away from the axis of the separating ring from the second connecting portion to the first connecting portion.

[0012] By adopting the above technical solution, when the urine bag needs to be replaced, medical staff separate the urine drainage tube from the ureteral single-J tube through the guiding action of the slope, which is beneficial to improving the speed of medical staff in replacing the urine bag.

[0013] Optionally, the second connecting portion is sequentially provided with a node-shaped contraction in a direction away from the separating ring.

[0014] By adopting the above technical solution, when the ureteral single-J tube needs to be replaced, the node-shaped contraction-set second connecting portion increases the friction between the fingers of medical staff and the outer peripheral surface of the second connecting portion, which is beneficial to medical staff in quickly replacing the ureteral single-J tube.

[0015] Optionally, the length dimension of the first connecting portion is smaller than the length dimension of the second connecting portion.

[0016] By adopting the above technical solution, the first connecting portion is sleeved on the outer peripheral surface of the catheter. The first connecting portion with a larger length dimension than the second connecting portion is beneficial to reducing the occurrence of the situation where one end of the catheter close to the first connecting portion bends or slips out of the first connecting cavity.

[0017] Optionally, the first connecting portion, the second connecting portion and the separating ring are integrally connected.

[0018] By adopting the above technical solution, the first connecting portion, the second connecting portion and the separating ring are integrally connected, which is beneficial to reducing the production difficulty of the single-J ureteral catheter with a relatively small volume, and thus is beneficial to improving the production quality of the single-J ureteral catheter.

[0019] Optionally, the materials of the first connecting portion, the second connecting portion and the separating ring are all selected as plastic or silicone.

[0020] By adopting the above technical solution, the first connecting portion, the second connecting portion and the separating ring made of plastic or silicone have less irritation to patients and lower weight. On the one hand, it is beneficial to ensure the comfort of patients, and on the other hand, it is beneficial to reduce the occurrence of the single-J ureteral catheter falling off under its own weight.

[0021] Optionally, the corners are chamfered.

[0022] By adopting the above technical solution, the chamfered corners are beneficial to reducing the occurrence of secondary injuries caused by the edges of the single-J ureteral catheter scratching patients with poor health.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When using the urinary catheter, first insert the first connecting portion into the connecting joint and make the outer peripheral surface of the first connecting portion tightly fit against the inner wall of the connecting joint. Then insert the catheter into the second connecting cavity and make the outer peripheral surface of the catheter tightly fit against the inner wall of the second connecting cavity. Finally, fixedly insert and fit the urine drainage hose to the first connecting portion and make the inner wall and the outer peripheral surface of the urine drainage hose tightly fit against the outer peripheral surface of the first connecting portion and the inner wall of the connecting joint respectively, so that it is difficult for urine to leak between the catheter and the urine drainage hose, thus ensuring hygiene.

[0025] 2. When the urine bag needs to be replaced, medical staff separate the urine drainage tube from the single-J ureteral catheter through the guiding action of the inclined surface, which is beneficial to improving the speed of medical staff replacing the urine bag.

[0026] 3. The first connecting portion is sleeved on the outer peripheral surface of the catheter. The first connecting portion with a larger length dimension than the second connecting portion is beneficial to reducing the occurrence of the end of the catheter near the first connecting portion being bent or slipping out of the first connecting cavity.

[0030] The following further elaborates on this application with reference to the Figure 1-2 accompanying drawings.

[0031] An embodiment of this application discloses a ureteral single-J stent. Referring to Figure 1 , the ureteral single-J stent includes a connecting pipe body 1 and a partition ring 2. The corners of the connecting pipe body 1 and the partition ring 2 are both chamfered.

[0032] Referring to Figure 1 , the connecting pipe body 1 is arranged in a circular tubular shape, the partition ring 2 is arranged in a circular ring shape, and the partition ring 2 is coaxially and fixedly sleeved on the outer peripheral surface of the connecting pipe body 1. A plurality of anti-slip grooves 201 are formed on the outer peripheral surface of the partition ring 2. The plurality of anti-slip grooves 201 are evenly distributed circumferentially around the axis of the partition ring 2, and the anti-slip grooves 201 extend along the axis of the partition ring 2, so as to increase the friction between the fingers of medical staff and the partition ring 2 when the ureteral single-J stent needs to be replaced, thereby facilitating the more smooth insertion of the connecting pipe body 1 into the urinary catheter or the more smooth insertion of the catheter into the connecting pipe body 1 by rotating the partition ring 2.

[0033] Referring to Figure 1 , the connecting pipe body 1 includes a first connecting portion 11 and a second connecting portion 12. The partition ring 2 is arranged between the first connecting portion 11 and the second connecting portion 12, and the length dimension of the first connecting portion 11 is greater than the length dimension of the second connecting portion 12. The first connecting portion 11, the second connecting portion 12, and the partition ring 2 are integrally connected, so as to reduce the production difficulty of the ureteral single-J stent with a relatively small volume, thereby facilitating ensuring the normal use of the ureteral single-J stent and reducing the discomfort of patients. The materials of the first connecting portion 11, the second connecting portion 12, and the partition ring 2 are all selected as plastic or silicone. In the embodiment of this application, the materials of the first connecting portion 11, the second connecting portion 12, and the partition ring 2 are all selected as silicone.

[0034] Referring to Figure 1 , an inclined surface 202 is arranged on one side of the partition ring 2 close to the first connecting portion 11. The inclined surface 202 is arranged in a circular ring shape coaxial with the partition ring 2, and the inclined surface 202 is inclined away from the axis of the partition ring 2 from the second connecting portion 12 to the first connecting portion 11, so as to facilitate the separation of the ureteral single-J stent by medical staff.

[0035] Referring to Figure 1 and Figure 2, a first connection cavity 101 is formed through the interior of the first connection portion 11, and the first connection cavity 101 is circular. The first connection cavity 101 is coaxially arranged with the connecting pipe body 1, and the outer diameter of the first connection cavity 101 is larger than the inner diameter of the connection joint; a second connection cavity 102 is formed through the interior of the second connection portion 12, and the second connection cavity 102 is circular. The second connection cavity 102 is coaxially arranged with the connecting pipe body 1, and the inner diameter of the second connection cavity 102 is smaller than the outer diameter of the catheter, and the first connection cavity 101 communicates with the second connection cavity 102.

[0036] Referring to Figure 1 , one end of the first connection portion 11 away from the separation ring 2 is constricted, that is, the inner diameter of the end of the first connection portion 11 away from the separation ring 2 is smaller than the inner diameter of the end of the first connection portion 11 close to the separation ring 2, so as to facilitate medical staff to insert the first connection portion 11 into the connection joint.

[0037] Referring to Figure 1 , the second connection portion 12 is sequentially constricted in a joint shape in the direction away from the separation ring 2, that is, the second connection portion 12 is divided into a plurality of pipe sections with different outer diameters along its own axis direction, and the outer diameter of the pipe section closer to the separation ring 2 is larger, so as to facilitate medical staff to remove the ureteral single J tube.

[0038] The implementation principle of a ureteral single J tube in an embodiment of the present application is as follows: when using a urinary catheter, first, rotate and insert the first connection portion 11 into the connection joint through the anti-slip groove 201, and make the outer peripheral surface of the first connection portion 11 tightly fit against the inner wall of the connection joint, and make the first connection portion 11 tightly fit against one side of the separation ring 2. Then insert the catheter into the second connection cavity 102, and make the outer peripheral surface of the catheter tightly fit against the inner wall of the second connection cavity 102, and make the second connection portion 12 tightly fit against the other side of the separation ring 2. Finally, fixedly plug and fit the urine drainage hose to the first connection portion 11, and make the inner wall and the outer peripheral surface of the urine drainage hose tightly fit against the outer peripheral surface of the first connection portion 11 and the inner wall of the connection joint respectively, so that it is difficult for urine to leak between the catheter and the urine drainage hose, thus ensuring hygiene.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
