Description

Technical Field

[0001] The present application relates to the technical field of urinary catheterization bags, and in particular to a urinary catheterization bag for preventing backflow. Background Art

[0002] During clinical treatment, especially when patients need to discharge urine in operating rooms, emergency rooms or wards, a catheter bag is needed to assist patients in urinating and collect urine.

[0003] The existing patent (publication number: CN201668574U) discloses a disposable painless sterile catheter bag, which includes a urine storage bag body and a catheter connected to the urine storage bag body, characterized in that: a one-way guide check valve for pushing out the catheter is arranged at the upper end of the urine storage bag, the catheter is stored in the urine storage bag, and a limiting ring edge with an outer diameter greater than the inner diameter of the catheter insertion channel arranged at the bottom of the one-way guide check valve tube is arranged at the end of the catheter; the valve cavity of the one-way guide check valve is filled with pre-injected lubricating silica gel, and a sealing patch for closing the catheter push-out port is arranged at the catheter push-out port of the one-way guide check valve. The structural features of the utility model can make the operator no longer need to touch the sterile catheter to be entered into the urethra with his hands, thereby reducing the possibility of urinary tract infection. The lubricant pre-placed in the guide check valve cavity and the smooth outer surface of the catheter will greatly reduce the pain during insertion.

[0004] In order to better judge the effect of drug treatment during the use of a disposable catheter bag pointed out in the above patent, medical staff need to observe the patient's urine output each time. However, the connector of the above catheter bag is directly connected to the catheter when in use, so the inside of the catheter bag is in a semi-sealed state during use. During use, due to the small amount of air inside the catheter bag, it cannot be fully expanded when urine falls into the catheter bag, resulting in different volumes of the catheter bag, resulting in inaccurate urine scale, which may affect the medical staff's accurate assessment of the urine volume. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a urinary catheter bag that prevents backflow, has the advantages of more accurate readings, etc., and solves the problem that the connector of the urinary catheter bag is directly connected to the urinary catheter when in use. Therefore, the interior of the urinary catheter bag is in a semi-sealed state during use. During use, due to the small amount of air inside the urinary catheter bag, it cannot be fully expanded when urine falls into the urinary catheter bag, resulting in different volumes of the urinary catheter bag, resulting in inaccurate urine scale, which may affect the medical staff's accurate assessment of the urine volume.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a urinary catheter bag for preventing backflow, comprising a urinary catheter bag, a connecting piece is fixedly connected to the outside of the urinary catheter bag, scale lines are fixedly set on the surface of the urinary catheter bag, an air inlet pipe is fixedly connected to one side of the upper end of the urinary catheter bag, a fixing ring is fixedly connected to the upper end of the air inlet pipe, a rotating cover is rotatably connected to the upper end of the fixing ring, and two air inlet holes are opened at the lower end of the rotating cover.

[0007] A threaded block is connected to the internal thread of the rotating cover, a sealing ring is fixedly connected to the lower end of the threaded block, a sealing block is fixedly connected to the lower end of the sealing ring, two sliding grooves are provided inside the air intake pipe, a guide ring is slidably connected between the two sliding grooves, a connecting rod is fixedly connected to the upper end of the guide ring, and the upper end of the connecting rod is fixedly connected to the lower end of the sealing block.

[0008] According to the above scheme, an air inlet pipe is fixedly connected to the upper end of the urine catheter bag body, a fixed ring is fixedly connected to the upper end of the air inlet pipe, and a rotating cover is rotatably connected inside the fixed ring. When the patient finishes urinating and the medical staff records the urination, the rotating cover is rotated, which will drive the threaded block to move upward through the threaded connection, thereby driving the guide ring to move inside the sliding groove. The guide ring is used to limit the movement trajectory of the connecting rod when in use. At the same time, it will drive the sealing ring and the sealing block to move upward until the sealing ring moves to the upper end of the air inlet hole. At the same time, when the sealing block is no longer in contact with the air inlet pipe, air will enter the urine catheter bag body through the air inlet hole and the air inlet pipe, so that the air inside the urine catheter bag body is sufficient, and the air pressure on both sides of the urine catheter bag body 1 is kept balanced, so that the urine catheter bag body can be fully stretched under the action of gravity, and the reading is more accurate.

[0009] Furthermore, a liquid outlet pipe is fixedly connected to the lower end of the urine catheter bag body, and a sealing cover is threadedly connected to the lower end of the liquid outlet pipe.

[0010] According to the above solution, after urination is completed, the sealing cover is unscrewed to discharge the urine in the urine catheter bag body through the liquid outlet tube.

[0011] Furthermore, a connecting tube is fixedly connected to the upper end of the urine catheter bag, and a one-way valve is fixedly connected to the upper end of the connecting tube.

[0012] Through the above solution, the one-way valve can prevent urine in the catheter bag from flowing back and contaminating the catheter during use.

[0013] Furthermore, a connecting piece is fixedly connected to the upper end of the one-way valve.

[0014] Through the above solution, the connector is used to connect with the urinary catheter when in use.

[0015] Furthermore, three anti-skid rubber pads distributed in a linear array are fixedly connected to the surface of the urine catheter bag.

[0016] Through the above solution, the anti-skid rubber pad can increase the friction between the catheter bag and the legs during use, and can prevent the catheter bag from being displaced significantly during use.

[0017] Furthermore, second connecting blocks are fixedly connected to both sides of the upper end of the connecting piece, and second ties are fixedly connected to the surfaces of two second connecting blocks.

[0018] With the above solution, the two second ties are tied together during use to limit the position of the urine catheter bag.

[0019] Furthermore, first connecting blocks are fixedly connected to both sides of the lower end of the connecting piece, and first ties are fixedly connected to the surfaces of the two first connecting blocks.

[0020] According to the above scheme, when in use, the urine catheter bag is attached to the leg, and then the two first ties are tied together.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The urinary catheter bag for preventing backflow has an air inlet pipe fixedly connected to the upper end of the urinary catheter bag body, a fixed ring fixedly connected to the upper end of the air inlet pipe, and a rotating cover rotatably connected inside the fixed ring. When in use, when the patient finishes urinating and the medical staff records the urination, the rotating cover is rotated to drive the threaded block to move upward through the threaded connection, thereby driving the guide ring to move inside the sliding groove, and at the same time driving the sealing ring and the sealing block to move upward until the sealing ring moves to the upper end of the air inlet hole. At the same time, when the sealing block is no longer in contact with the air inlet pipe, air will enter the interior of the urinary catheter bag body through the air inlet hole and the air inlet pipe, so that the air inside the urinary catheter bag body is sufficient, and the air pressure on both sides of the urinary catheter bag body is kept balanced, so that the urinary catheter bag body can be fully stretched under the action of gravity, and the reading is more accurate.

During use, air will enter the air inlet pipe 12 from the two air inlet holes 20. The lower end of the urine catheter bag body 1 is fixedly connected to a liquid outlet pipe 22, and the lower end of the liquid outlet pipe 22 is threadedly connected to a sealing cover 23. After urination is completed, the sealing cover 23 is unscrewed to discharge the urine in the urine catheter bag body 1 through the liquid outlet pipe 22.

[0032] See also Figure 1 and Figure 2The outside of the urine catheter bag body 1 is fixedly connected with a connecting piece 2, and a scale line 3 is fixedly set on the surface of the urine catheter bag body 1. A connecting tube 4 is fixedly connected to the upper end of the urine catheter bag body 1, and a one-way valve 5 is fixedly connected to the upper end of the connecting tube 4.
