Description

Technical Field

[0001] The present application relates to the technical field of urinary catheters, and in particular to an air bag diaphragm push valve. Background Art

[0002] The balloon catheter is a commonly used clinical urine drainage device. The front of the tube is provided with a catheter hole connected to the lumen, and a balloon for preventing the front end of the catheter from escaping from the bladder. The rear of the tube is provided with an inflation port connected to the balloon, and the end is a urination port.

[0003] The existing patent (publication number: CN215135648U) discloses a urinary catheter, including a tube body and a balloon, wherein the tube body has a proximal end and a distal end, the tube body has a urination channel and an inflation channel, the proximal end is provided with a first suction port and a vent, the first suction port is connected to one end of the urination channel, the vent is connected to one end of the inflation channel, the distal end has a first joint and a second joint, the first joint is connected to the other end of the urination channel, and the second joint is connected to the other end of the inflation channel; the balloon is sleeved outside the tube body and adjacent to the proximal end, and the balloon is connected to the inflation channel through the vent, so as to inflate the balloon through the inflation channel; the tube body is also provided with a second suction port, the second suction port is located at a predetermined distance behind the balloon, and the second suction port is connected to the urination channel. The urinary catheter provided according to the embodiment of the utility model can discharge urine more fully and reduce urine residue.

[0004] However, when the urinary catheter pointed out in the above patent is in use, the first liquid suction port is always in a conducting state, and a little urine in the bladder will be discharged, which causes the bladder to be in an empty state for a long time. The bladder is in an empty state for a long time, which will cause the stress relaxation function of the bladder detrusor, internal and external sphincters to decline. In severe cases, it can cause the bladder's urine storage function and urination reflex to weaken, thereby causing a gradual decline in bladder function and ultimately leading to disuse atrophy of bladder function. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides an airbag diaphragm push valve, which has the advantages of delaying catheterization, etc., and solves the problem that the first suction port of the catheter is always in a conductive state when in use, and a little urine in the bladder will be discharged, which causes the bladder to be in an empty state for a long time. The bladder is in an empty state for a long time, which will cause the stress relaxation function of the bladder detrusor muscle, internal and external sphincters to decline. In severe cases, it can cause the bladder's urine storage function and urination reflex to weaken, thereby causing the bladder function to gradually decline, and finally leading to disuse atrophy of the bladder function.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an airbag diaphragm push valve, comprising a urinary catheter, a mounting plate fixedly connected inside the urinary catheter, two mounting grooves are provided at the lower end of the mounting plate, sliding columns are slidably connected inside the two mounting grooves, a lifting plate is fixedly connected to the lower ends of the two sliding columns, a lifting column is fixedly connected to the lifting plate, an outflow hole is provided in the middle of the mounting plate, a rubber plug is fixedly connected to the upper end of the lifting column through the outflow hole, and a lifting platform is fixedly connected to the upper end of the rubber plug;

[0007] The outer wall of the catheter is fixedly connected to an airbag, a connection hole is opened at a position of the side wall of the catheter corresponding to the airbag, a mounting block is fixedly connected to a position of the inner wall of the catheter corresponding to the connection hole, a sliding groove is opened inside the mounting plate, and a slider is slidably connected inside the sliding groove.

[0008] Through the above scheme, during use, the spring at the lower end of the mounting plate will exert a downward force on the lifting plate. Only when a certain amount of urine is stored in the bladder, the pressure inside the bladder will cause the airbag to sink downward, thereby driving the slider to move in the direction of the lifting plate, and then driving the lifting plate to rise, and then driving the rubber plug to rise until the lower surface of the rubber plug is no longer in contact with the mounting plate. At this time, urine can flow out of the outflow hole, which can prevent the bladder from being in an empty state for a long time during use. If the bladder is in an empty state for a long time, the stress relaxation function of the bladder detrusor, internal and external sphincters will decrease. In severe cases, the bladder's urine storage function and urination reflex will be weakened, which will lead to a gradual decline in bladder function and ultimately disuse atrophy of bladder function.

[0009] Furthermore, a spring is fixedly connected to the lower end of the mounting plate, and the lower end of the spring is fixedly connected to the upper end of the lifting plate.

[0010] Through the above solution, during use, the spring will apply a downward force to the lifting plate, thereby preventing urine from flowing out of the outflow hole.

[0011] Furthermore, a sealing gasket is slidably connected inside the sliding groove, and a surface of the sealing gasket is fixedly connected to one end of the sliding block.

[0012] Through the above solution, the possibility of liquid or gas leakage can be reduced by sliding the connection sealing gasket in the sliding groove.

[0013] Furthermore, one end of the sliding block extends out of the mounting block and abuts against the lower end of the lifting plate.

[0014] With the above solution, when in use, the movement of the slider toward the lifting plate will drive the lifting plate to rise.

[0015] Furthermore, a catheter head is fixedly connected to the upper end of the catheter.

[0016] Through the above solution, the catheter head can facilitate medical staff to insert the catheter, reducing the difficulty of operation and the pain of patients.

[0017] Furthermore, two urinary catheter holes are provided at the upper end of the urinary catheter.

[0018] Through the above scheme, the two catheter holes can increase the efficiency of urine discharge and reduce the patient's discomfort during urination.

[0019] Furthermore, the urinary catheter is made of medical rubber.

[0020] Through the above solution, the medical rubber material is soft and will not cause irritation to the urethral mucosa and surrounding tissues.

[0021] Furthermore, a closed space is formed between the airbag through the connecting hole and the sliding groove inside the mounting block.

[0022] Through the above solution, water or air can be injected into the enclosed space formed by the airbag, the connecting hole and the sliding groove inside the mounting block during use.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The airbag diaphragm push valve has a spring at the lower end of the mounting plate that applies a downward force to the lifting plate during use. Only when a certain amount of urine is stored in the bladder will the pressure inside the bladder cause the airbag to sag inward, thereby driving the slider to move in the direction of the lifting plate, and then driving the lifting plate to rise, and then driving the rubber plug to rise until the lower surface of the rubber plug is no longer in contact with the mounting plate. At this time, urine can flow out of the outflow hole, which can prevent the bladder from being in an empty state for a long time during use. If the bladder is in an empty state for a long time, the stress relaxation function of the bladder detrusor, internal and external sphincters will decrease. In severe cases, the bladder's urine storage function and urination reflex will be weakened, which will lead to a gradual decline in bladder function and ultimately disuse atrophy of bladder function.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1 , Figure 2 and Figure 4 In this embodiment, an airbag diaphragm push valve includes a urinary catheter 1. A urinary catheter head 2 is fixedly connected to the upper end of the urinary catheter 1. The urinary catheter head 2 can facilitate medical staff to insert the urinary catheter 1, reduce the difficulty of operation and the pain of the patient. Two urinary catheter holes 3 are provided on the upper end of the urinary catheter 1. The urinary catheter 1 is made of medical rubber. The two urinary catheter holes 3 can increase the efficiency of urine discharge and reduce the patient's discomfort when urinating.

[0033] At the same time, a mounting plate 5 is fixedly connected to the middle part of the inner wall of the urinary catheter 1, and two mounting grooves 6 are provided at the lower end of the mounting plate 5. Sliding columns 7 are slidably connected inside the two mounting grooves 6. A lifting plate 8 is fixedly connected to the lower ends of the two sliding columns 7. A lifting column 10 is fixedly connected inside the lifting plate 8. An outflow hole 13 is provided in the middle part of the mounting plate 5. The upper end of the lifting column 10 passes through the outflow hole 13 and is fixedly connected to a rubber plug 11. The upper end of the rubber plug 11 is fixedly connected to a lifting platform 12. A spring 9 is fixedly connected to the lower end of the mounting plate 5. The lower end of the spring 9 is fixedly connected to the upper end of the lifting plate 8. During use, the spring 9 will apply a downward force to the lifting plate 8, thereby preventing urine from flowing out of the outflow hole 13.

[0034] See also Figure 1 , Figure 2 and Figure 3The outer wall of the catheter 1 is fixedly connected with an airbag 4, a connecting hole 14 is opened at a position of the side wall of the catheter 1 corresponding to the airbag 4, a mounting block 15 is fixedly connected at a position of the inner wall of the catheter 1 corresponding to the connecting hole 14, a sliding groove 16 is opened inside the mounting plate 5, the airbag 4 forms a closed space between the sliding groove 16 inside the mounting block 15 through the connecting hole 14, a slider 18 is slidably connected inside the sliding groove 16, a sealing gasket 17 is slidably connected inside the sliding groove 16, the surface of the sealing gasket 17 is fixedly connected to one end of the slider 18, and the possibility of liquid or gas leakage can be reduced by slidingly connecting the sealing gasket 17 in the sliding groove 16. One end of the slider 18 extends out of the mounting block 15 and abuts against the lower end of the lifting plate 8. When in use, the movement of the slider 18 in the direction of the lifting plate 8 will drive the lifting plate 8 to rise.

[0035] In this embodiment, during use, the spring 9 at the lower end of the mounting plate 5 will apply a downward force to the lifting plate 8. Only when a certain amount of urine is stored in the bladder, the pressure inside the bladder will cause the airbag 4 to sink inward, thereby driving the slider 18 to move in the direction of the lifting plate 8, and then driving the lifting plate 8 to rise, and then driving the rubber plug 11 to rise, until the lower surface of the rubber plug 11 is no longer in contact with the mounting plate 5. At this time, urine can flow out from the outflow hole 13, which can prevent the bladder from being in an empty state for a long time during use. If the bladder is in an empty state for a long time, the stress relaxation function of the bladder detrusor, internal and external sphincters will decrease. In severe cases, the urine storage function and urination reflex of the bladder will be weakened, which will lead to a gradual decline in bladder function and eventually cause disuse atrophy of bladder function.

[0036] It should be noted that the mounting groove 6 and the sliding column 7 can play a guiding role in actual use.

[0037] The working principle of the above embodiment is:

[0038] When in use, first insert the urinary catheter 1 into the bladder through the patient's urethra, and then fill water or gas into the airbag 4. During use, the spring 9 at the lower end of the mounting plate 5 will apply a downward force to the lifting plate 8. Only when the urine in the bladder is stored to a certain amount, the pressure inside the bladder will cause the airbag 4 to sink inward, thereby driving the slider 18 to move in the direction of the lifting plate 8, and then driving the lifting plate 8 to rise, and then driving the rubber plug 11 to rise until the lower surface of the rubber plug 11 is no longer in contact with the mounting plate 5. At this time, urine can flow out from the outflow hole 13, which can prevent the bladder from being in an empty state for a long time during use. If the bladder is in an empty state for a long time, the stress relaxation function of the bladder detrusor, internal and external sphincters will decrease. In severe cases, the urine storage function and urination reflex of the bladder will be weakened, which will lead to a gradual decline in bladder function and eventually cause disuse atrophy of bladder function.
