[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] According to the detrusor pressure wireless pressure measuring system of the embodiment of the present invention, the detrusor pressure wireless pressure measuring system includes a bladder pressure measuring device, an abdominal pressure measuring device and a signal receiving device. The bladder pressure measuring device includes a pressure measuring body 1 and a recovery line 2. The pressure measuring body 1 includes a deformable shell, a first pressure sensor, a first pressure analysis device and a first signal transmitting device. The first pressure sensor, the second pressure analysis device and the first signal transmitting device are located in the deformable shell. The first pressure analysis device is electrically connected to the first pressure sensor, and the first signal transmitter is electrically connected to the first pressure analysis device for transmitting a signal. The recovery line 2 is connected to the deformable shell. The abdominal pressure measuring device includes a measuring body 3 and a pressure probe 4. The first end of the measuring body 3 is detachably connected to the pressure probe 4. A pull ring 10 is provided at the second end of the measuring body 3. A second pressure analysis device and a second signal transmitting device are provided in the measuring body 3. The pressure analysis device is electrically connected to the pressure probe 4. The second signal transmitter is electrically connected to the pressure analysis device for transmitting a signal. The signal receiving device includes a signal receiver and a storage. The signal receiver is used to receive data sent by the first signal transmitting device and the second signal transmitting device, and the storage is used to store data. The bladder pressure measuring device measures the pressure change in the bladder through the pressure measuring body 1. The recovery line 2 is connected to the pressure measuring body 1 to recover the pressure measuring body 1, so that the pressure measuring body 1 can be completely placed inside the bladder for measurement, avoiding the influence of the catheter on the contraction of the bladder outlet when measuring the pressure in the bladder. The abdominal pressure measuring device reflects the change of abdominal pressure by measuring the rectal pressure, and the detrusor pressure is the difference between the bladder pressure and the abdominal pressure. The signal receiving device receives the pressure information and can perform an overall analysis of the pressure information, which is convenient for the user to judge the detrusor pressure state.

[0019] The wireless detrusor pressure measurement system according to the embodiment of the present invention has the advantages of little impact on the patient and continuous monitoring of pressure changes.

[0020] In some embodiments, support rings 5 ​​are provided at both ends of the pressure measuring body 1, and the two support rings 5 ​​are connected by a plurality of elastic support rods 6, the support rings 5 ​​are connected to the pressure measuring body 1 through a connecting piece, the hook is connected to the connecting piece through a connecting line and hooked with the support ring 5, the release rod 8 is threadedly connected to the connecting piece, and the first end of the release rod 8 is pivotally connected to the pressure measuring body 1.

[0021] Specifically, the two support rings 5 ​​can cooperate with multiple elastic support rods 6 to support the side of the pressure measuring body 1 to form a hollow structure, so as to prevent the pressure measuring body 1 from blocking the bladder outlet. The hook is connected to the connector through a connecting line and hooked with the support ring 5 so that the elastic support rod 6 on the side of the pressure measuring body 1 is close to the pressure measuring body 1 and the whole is kept in a tightened state for easy delivery into the bladder. As the cystoscope delivers the pressure measuring body 1 into the bladder, the release rod 8 is rotated to make the connector rotate and push the elastic support rod 6 away from the pressure measuring body 1. The support rings 5 ​​are close to each other, and the connection line is relaxed, causing the hook to bend and relax the elastic support rod 6 to complete the expansion of the hollow structure. The recovery line 2 is placed outside the body through the urethra to facilitate the recovery of the pressure measuring body 1. Optionally, there are two or more hooks, and two connecting lines are connected to the hooks respectively, which can maintain the balance between the connector and the support ring and avoid the tilt of the support ring caused by unilateral hooking.

[0022] In some embodiments, the connecting member includes a connecting ring and a connecting rod 7, the connecting ring has an internal thread for threaded connection with the release rod 8, multiple connecting rods 7 are evenly distributed around the connecting ring, the first end of the connecting rod 7 is connected to the connecting ring, the second end of the connecting rod 7 is connected to the support ring 5, and the connecting line is connected to the connecting ring.

[0023] Specifically, a plurality of connecting rods 7 are distributed at equal angles in the circumferential direction of the connecting ring, the connecting ring and the support ring 5 are connected by the connecting rods 7, the diameter of the connecting ring is much smaller than the diameter of the support ring 5, and the connecting ring, the support ring 5 and the plurality of connecting rods 7 form a conical hollow structure. The conical hollow structure is symmetrically arranged at both ends of the pressure measuring body 1 to prevent the pressure measuring body 1 from blocking the bladder outlet. The connecting wire is connected to the connecting ring, and the length of the connecting wire is equal to or slightly smaller than the length of the connecting rod so that the connecting wire remains taut when the hook is hooked with the support ring 5, and the connecting wire relaxes as the connecting ring moves driven by the release rod 8.

[0024] In some embodiments, the distance between the two support rings 5 ​​changes with the deformation of the elastic support rod 6 .

[0025] Specifically, the elastic support rod 6 supports the two support rings 5. As the hook is hooked onto one of the support rings 5, the elastic support rod 6 bends and deforms to shorten the distance between the two support rings 5, thereby completing the lateral extension of the pressure measuring body 1.

[0026] In some embodiments, the deformable housing is an arc-shaped member, a first end of the arc-shaped member is connected to the recovery line 2, and a second end of the arc-shaped member is curled toward the first end of the arc-shaped member.

[0027] Specifically, when the deformable shell is an arc-shaped piece, the arc-shaped piece can be made of a memory deformation material, and the arc-shaped piece can automatically return to a curled state after being deformed under the action of an external force. The curled arc-shaped piece can reduce the space occupied in the bladder and can also prevent the arc-shaped piece from completely closing the bladder outlet. Under the external force of the recovery line 2, the arc-shaped piece can be deformed and separated from the bladder. (The effect of the bending of the pressure measuring device)

[0028] In some embodiments, the measuring body 3 has a spindle-shaped shell, the diameters of both ends of the spindle-shaped shell increase as the distance from the center of the spindle-shaped shell decreases, and the diameter change rate of one end of the spindle-shaped shell is greater than the diameter change rate of the other end of the spindle-shaped shell.

[0029] Specifically, the measuring body 3 is used to be placed in the rectum, and the spindle-shaped shell can prevent the measuring body 3 from falling out of the rectum. The two ends of the spindle-shaped shell have small diameters and a large middle diameter, and the rates of change of the diameters at the two ends from the end to the middle are different, with one end changing less in diameter and the other end changing more in diameter.

[0030] In some embodiments, the abdominal pressure measuring device further includes a protective pad 9, which is located at the second end of the measuring body 3 to prevent the measuring body 3 from completely entering the intestine.

[0031] Specifically, the protection pad 9 is used to play a role of limiting. The protection pad 9 can be made of silicone. The protection pad 9 can be a flat sheet with a diameter larger than the measurement body 3. The protection pad 9 has a certain elasticity.

[0032] In some embodiments, the pressure probe 4 is threadedly connected to the first end of the measuring body 3 , and the pressure probe 4 is a cylinder.

[0033] Specifically, the pressure probe 4 is in the shape of a cylinder, the detection section of the pressure probe 4 is a smooth ball head, the pressure probe 4 is electrically connected to the measuring body 3 through a connector, the pressure probe 4 is disposable, and the pressure probe is threadedly connected to the measuring body 3 for easy disassembly and replacement to ensure hygiene.
