Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a urinary catheter connector for postoperative nursing of bladder tumors. Background Art

[0002] After transurethral bladder tumor resection, a wound will be left in the bladder. In order to maintain the bladder at a low pressure and allow it to heal gradually after adequate rest, it is necessary to place a urinary catheter after surgery. However, for the wound site, medical staff usually need to apply medicine frequently. The ordinary double-lumen urinary catheter connector has only one drainage cavity in addition to the balloon cavity; and the three-lumen urinary catheter is prone to urine residue when filling the cavity due to its structural limitations, which may cause urine leakage during the operation.

[0003] There are some new catheter connectors that hope to solve this problem. For example, patent publication number CN210331363U discloses a catheter connector for postoperative care of bladder tumors. The device sets a one-way structure in the drug delivery tube, so that when filling the bladder with medicine, it is only necessary to extend the tube into the drug delivery tube, thereby reducing the operation steps and avoiding the possible leakage of residual urine. By setting a barrel and a hinged structure therein, the slider is pushed and the angle between the hinged structures is reduced, so that the catheter sleeved outside the main connector can be fixed by the squeezing effect, reducing the possibility of accidental detachment and ensuring the normal use of the device.

[0004] However, the device also has certain shortcomings. On the one hand, the device is provided with an anti-backflow diaphragm on the urinary catheter. Although the structure of the anti-backflow diaphragm is not described in detail in the specification, generally speaking, the one-way valve structure requires a certain pressure at the liquid inlet end, and the urinary catheter is difficult to allow urine to pass through the anti-backflow diaphragm in one direction only by gravity. In addition, the device only provides a drug delivery tube outside the urinary catheter, which cannot meet the complex needs of drug application, flushing, etc.

[0005] Therefore, there is a need for a catheter connector for postoperative care of bladder tumors. One end of the device is connected to the drainage cavity of a traditional catheter and is provided with a self-locking mechanism to ensure the stability of the connection between the device and the catheter. In addition, while retaining the basic function of urine drainage, the device is additionally provided with a medicine application port and a flushing port. In addition, during the flushing process, the urination port may not discharge sufficiently or in a timely manner. Therefore, the device is additionally provided with a drainage port, and the auxiliary urination port is used for drainage. Summary of the invention

[0006] In order to solve the above technical problems, the present invention designs a catheter connector for postoperative care of bladder tumors. The device is connected to an ordinary catheter connector through a connector, and the compression roller inside the locking clamp is used to fix the connector and the ordinary catheter connector; at the same time, the device is respectively provided with a urination port, a liquid discharge port, a flushing port, and a medicine application port at the end of the connector; the urination port of the device is connected to an ordinary urine collection bag; at the same time, a ball valve is provided outside the urination port and the liquid discharge port of the device to ensure that the device can close the ball valve when the drug application operation is performed or no liquid collection is required, and the drug or flushing liquid will not flow out from the urination port and the liquid discharge port. At the same time, when the ball valve is opened, the urine in the bladder can enter the urine collection bag through the urination port normally by gravity, without affecting the normal operation of the device; and a one-way valve is provided at the end of the flushing port and the medicine application port to ensure that the liquid will not flow out through the flushing port and the medicine application port to prevent contamination. At the same time, protective sleeves are provided at the upper and lower ends of the locking clamp of the device to protect the pipe connection and the pipe diversion to prevent damage.

[0007] In order to achieve the above technical effects, the present invention discloses a urinary catheter joint for postoperative nursing of bladder tumors, comprising: a shunt tube and a locking clip; the shunt tube is fixedly arranged inside the locking clip; Furthermore, the locking clamp includes: an inner ring, an outer ring, a spring, a compression roller, a rotating shaft, a first connecting rod, a first protective sleeve, a second connecting rod, a second protective sleeve, a fixed pressure rod, and a rotating pressure rod; the inner ring is rotatably arranged inside the outer ring, and the fixed pressure cover is fixedly arranged outside the outer ring; the rotating pressure rod is rotatably arranged outside the inner ring; the middle part of the rotating shaft is rotatably connected to the inner ring, one end of the rotating shaft is slidably connected to the outer ring, and the other end of the rotating shaft is rotatably connected to the compression roller; one end of the spring is fixedly connected to the rotating pressure rod, and the other end of the spring is fixedly connected to the inside of the outer ring; the first connecting rod is fixedly arranged at the top of the outer ring, and the first protective sleeve is fixedly arranged at the top of the first connecting rod; the second connecting rod is fixedly arranged at the bottom of the outer ring, and the second protective sleeve is fixedly arranged at the bottom of the second connecting rod; Further, the shunt pipe includes: a connector, a urination port, a liquid discharge port, a flushing port, a medicine application port, a first ball valve, a second ball valve, a first check valve, and a second check valve; the ends of the connector are respectively fixedly connected to the urination port, the liquid discharge port, the flushing port, and the medicine application port; Furthermore, the first one-way valve is fixedly connected to the urine outlet; the second one-way valve is fixedly connected to the liquid outlet; Furthermore, the first one-way valve is fixedly connected to the flushing port, and the liquid flows from the flushing port to the connecting head; the second one-way valve is fixedly connected to the medicine application port, and the liquid flows from the medicine application port to the connecting head; the ball valve includes: a valve body and a valve core; the valve core is rotatably arranged inside the valve body.

[0008] The beneficial effects of the present invention are: The present invention discloses a urinary catheter connector for postoperative nursing of bladder tumors. The device can simultaneously meet the multiple needs of urination, drainage, flushing and medication application through an integrated shunt tube, greatly improving the efficiency and convenience of postoperative nursing. This integrated design reduces the trouble of requiring multiple independent devices in traditional nursing and reduces the complexity of nursing work.

[0009] Secondly, the design of the locking clip and compression roller in the device ensures a stable connection with the ordinary catheter connector, reducing the risk of leakage or tube detachment due to unstable connection and improving the safety of nursing.

[0010] At the same time, by setting ball valves at the urination port and drainage port, the device can close these channels when needed to prevent accidental leakage of drugs or flushing solutions, and also allows the channels to be closed when liquid collection is not required, reducing the inconvenience during nursing. The one-way valve design at the end of the flushing port and the medication port prevents the backflow of liquid, ensures the correct flow of drugs and flushing solutions, and avoids external contamination.

[0011] Finally, the device’s protective sleeve design provides additional protection for pipe connections and diversions, preventing pipe damage due to external forces or accidental damage, and enhancing the durability and reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
