[0002] Normal people have bladder sensation. When the urine in the bladder increases to a certain pressure, they will feel the urge to urinate and urinate. Clinically, patients with coma, spinal cord injury, sequelae of stroke or diabetic peripheral neuropathy have decreased bladder sensation and weak contraction, and need to have a long-term catheter to drain urine. There are also perioperative patients, critically ill patients, prostate hyperplasia and other clinical cases that require short-term catheterization.

[0003] The existing patent (publication number: CN211243405U) discloses a dynamic bladder pressure monitoring device, including a shell with an inner cavity in the middle; a connecting tube connected to the shell and communicated with the inner cavity of the shell, the distal end of the connecting tube is inserted into the excretion port of a cystostomy tube or a urinary catheter; a pressure sensing unit is arranged in the inner cavity of the shell for detecting and monitoring bladder pressure.

[0004] The above-mentioned comparative document points out that the device can realize fully automatic continuous bladder pressure measurement, so that medical personnel can timely grasp the patient's bladder pressure situation and perform urination management. By detecting dynamic bladder pressure and combining the patient's urination diary, dynamic urodynamic examination can be realized. However, the device has many restrictions and is not convenient for patients to get out of bed. Since the device is large in size and inconvenient to move, it needs to be inserted again if the device is disassembled, which is more troublesome. Therefore, an intracavitary pressure detection device is proposed to solve the above problems. Utility Model Content

Since the device is large in size and inconvenient to move, if the device is disassembled, it needs to be inserted again, which is quite troublesome.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an intracavity pressure detection device, comprising a tube body, two semicircular blocks are fixedly provided on the upper end of the inner wall of the tube body, a fixing plate is fixedly provided on the end of the inner wall of the tube body away from the semicircular blocks, a spring is fixedly provided on the upper end of the fixing plate, an extrusion plate is fixedly provided on the end of the spring away from the fixing plate, a pressure sensor is connected to the internal thread of one side of the extrusion plate, a blocking block is fixedly provided on the upper end of the pressure sensor, and a liquid inlet is opened on one side of the tube body.

At the same time, the pressure sensor can be used to achieve the effect of automatic urination. Under the characteristics of the spring, the blocking block blocks the gap between the two semicircular blocks. When the pressure in the cavity is too large, the pressure generates a thrust on the blocking block, causing the blocking block to squeeze the spring downward, thereby generating a gap between the blocking block and the semicircular block. Urine flows out of the tube body through the gap. With the help of the pressure in the cavity, the function of automatic urination is achieved, and the pressure in the cavity can be reduced. At the same time, the device is small in size and is easy to move when the patient gets out of bed without disassembly.

[0008] Furthermore, an annular plate is fixedly disposed inside one end of the tube body away from the liquid inlet, and a liquid outlet pipe is fixedly disposed inside the annular plate.

[0009] Through the above scheme, the annular plate and the liquid outlet pipe are provided so that the liquid outlet pipe can perform the liquid discharge work. When the hook is hung on the extension tube, the guide wire and the hook can be prevented from contacting urine, thereby avoiding contamination.

[0010] Furthermore, a first through hole and a second through hole are respectively formed at both ends of the extrusion plate and the fixing plate.

[0011] Through the above solution, the interior of the first through hole and the second through hole is used to arrange the liquid blocking tube.

[0012] Furthermore, liquid blocking tubes are fixedly disposed inside the two first through holes and the second through holes, guide wires are fixedly disposed inside the two liquid blocking tubes, and the two guide wires are fixedly connected to the blocking block.

[0014] Furthermore, a hook is fixedly provided on one end of the two guide wires away from the blocking block.

[0015] Through the above scheme, the guide wire is pulled to shrink the spring and move the guide wire outward so that the hook can be hung on the outer wall of the extension tube. During artificial drainage, medical staff do not need to keep pulling the guide wire by hand.

[0016] Furthermore, an extension pipe is fixedly provided on one side of the pipe body, and a water injection hard valve is fixedly provided inside one side of the extension pipe.

[0017] Through the above scheme, the extension pipe is a hook-fixed structure, and the water injection hard valve is a water injection structure.

[0018] Furthermore, the water injection hard valve is fixedly connected to an air bag via a water injection pipe, and the air bag is fixedly arranged on the outer wall of the tube body.

[0019] Through the above scheme, water is injected into the water injection hard valve and flows into the airbag through the water injection pipe, so that the airbag is filled with water and swells, and the tube body is fixed inside the urethra through the swollen airbag.

[0020] Furthermore, an upper limit post and a lower limit post are fixedly provided on one side corresponding to the extrusion plate and the fixed plate, respectively, and the upper limit post and the lower limit post are both provided inside the spring.

[0021] Through the above solution, the upper limit post and the lower limit post are both arranged inside the spring and can limit the position of the spring.

[0023] The intracavity pressure detection device can detect the pressure in the cavity. The intracavity pressure can be measured by setting a pressure sensor. By connecting it with an external structure, the pressure can be observed and the fluid can be discharged in time. At the same time, the pressure sensor can be used to achieve the effect of automatic urination. Under the characteristics of the spring, the blocking block blocks the gap between the two semicircular blocks. When the intracavity pressure is too high, the pressure generates a thrust on the blocking block, causing the blocking block to squeeze the spring downward, thereby generating a gap between the blocking block and the semicircular block. Urine flows out of the tube body through the gap, and the pressure in the cavity is used to achieve the function of automatic urination. At the same time, it can also reduce the pressure in the cavity. At the same time, the device is small in size and is easy to move when the patient gets out of bed. It does not need to be disassembled. Artificial drainage can also be performed through the set guide wire and hook. The guide wire is pulled to shrink the spring, and the guide wire moves outward. A gap is generated between the blocking block and the semicircular block, allowing urine to flow into the tube body. The hook is hung on the outer wall of the extension tube. During artificial drainage, medical staff do not need to pull the guide wire with their hands all the time. By setting the annular plate and the liquid outlet pipe, the liquid inside the tube body is discharged through the liquid outlet pipe. When the hook is hung on the extension tube, it can prevent the guide wire and the hook from contacting urine to avoid contamination. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, the intracavity pressure detection device can detect the pressure in the cavity. By setting up a pressure sensor 4, the intracavity pressure can be measured. By connecting it to an external structure, the pressure can be observed and the fluid can be discharged in time. At the same time, the pressure sensor 4 is relied on to achieve the effect of automatic urination. Under the characteristics of the spring 7, the blocking block 3 blocks the gap between the two semicircular blocks 2. When the intracavity pressure is too large, the pressure generates a thrust on the blocking block 3, causing the blocking block 3 to squeeze the spring 7 downward, thereby generating a gap between the blocking block 3 and the semicircular block 2. Urine flows out of the tube body 1 through the gap, and the pressure in the cavity is used to achieve automatic urination. The function of automatic urination can also be achieved by reducing the pressure in the cavity. The guide wire 13 and the hook 14 are provided, and artificial drainage can also be performed. The guide wire 13 is pulled to shrink the spring 7, and a gap is generated between the blocking block 3 and the semicircular block 2, so that urine flows into the tube body 1. The guide wire 13 moves outward and the hook 14 is hung on the outer wall of the extension tube 19. During artificial drainage, the medical staff does not need to pull the guide wire 13 by hand all the time. By providing the annular plate 15 and the liquid outlet pipe 16, the liquid inside the tube body 1 is discharged through the liquid outlet pipe 16. When the hook 14 is hung on the extension tube 19, the guide wire 13 and the hook 14 can be prevented from contacting the urine to avoid contamination.

[0034] It should be noted that the two semicircular blocks 2 and the fixed plate 8 are fixed inside the tube body 1, the blocking block 3 and the extrusion plate 5 are slidably arranged inside the tube body 1, the pressure sensor 4 is connected to the external structure to display the pressure value, and the length of the liquid outlet pipe 16 is greater than the length of the extension tube 19 to avoid contamination of the guide wire 13 and the hook 14 during discharge.

[0035] The working principle of the above embodiment is:

[0036] When the device is in use, the pressure sensor 4 is connected to the external device, and the tube body 1 is inserted into the cavity. The pressure sensor 4 measures the pressure and displays it on the external device. When the pressure is too high, manual urination is performed. By pulling the guide wire 13, the spring 7 is contracted, and a gap is generated between the blocking block 3 and the semicircular block 2, so that urine flows into the tube body 1. The guide wire 13 moves outward so that the hook 14 can be hung on the outer wall of the extension tube 19. The liquid in the tube body 1 is discharged through the liquid outlet pipe 16. During manual drainage, the medical staff does not need to pull the guide wire 13 by hand all the time. When there is no medical staff around and it is inconvenient for the patient to operate, the automatic urination function can be used when the pressure in the cavity is too high. The pressure generates a thrust on the blocking block 3, so that the blocking block 3 squeezes the spring 7 downward, and a gap is generated between the blocking block 3 and the semicircular block 2. Urine flows out of the tube body 1 through the gap, and the automatic urination function is realized with the help of the pressure in the cavity.
