[0027] It is understandable that, referring to Figure 1 and Figure 2 The bladder pressure measuring device of the utility model comprises a support frame 100, an infusion mechanism 200 and a pressure measuring mechanism 300; the infusion mechanism 200 comprises an infusion bottle 210, a flushing tube 220 and an air inlet pipe 230, the infusion bottle 210 is arranged on the support frame 100, the flushing tube 220 and the air inlet pipe 230 are both connected with the infusion bottle 210, the flushing tube 220 is used to transport the liquid in the infusion bottle 210, and the air inlet pipe 230 is used to balance the air pressure inside and outside the infusion bottle 210; the pressure measuring mechanism 300 comprises a pressure measuring tube 310 , a urinary catheter 320, a three-way joint 330 and a pressure gauge 340. The flushing tube 220, the pressure gauge 310 and the urinary catheter 320 are all connected to the three-way joint 330. The pressure gauge 310 is vertically arranged on the support frame 100. The pressure gauge 340 is arranged adjacent to the pressure gauge 310. The urinary catheter 320 is connected to a metal wire 321. The metal wire 321 is passed through the urinary catheter 320. A through hole 322 is opened on the side wall of the urinary catheter 320. A sealing block 323 is connected to the end of the metal wire 321. The sealing block 323 can block the through hole 322.

[0028] The infusion bottle 210 is arranged on the support frame 100, the flushing tube 220 and the air inlet tube 230 are both connected to the infusion bottle 210, the flushing tube 220, the pressure measuring tube 310 and the urinary tube 320 are respectively connected to the three-way joint 330, and the metal wire 321 is passed through the urinary tube 320. By bending the metal wire 321, the shape of the urinary tube 320 can adapt to the shape of the patient's urethra, and the rigidity of the urinary tube 320 can be increased, so that the insertion of the urinary tube 320 can be facilitated, the time for arranging the urinary tube 320 can be shortened, and the pain of the patient can be alleviated. The end of the metal wire 321 is connected with a sealing block 323, and the sealing block 323 can block the through hole 322 to prevent the urine in the patient's bladder from entering the through hole 322 when the urinary tube 320 is inserted, thereby improving the convenience of operation for medical staff. The liquid in the infusion bottle 210 is transported through the flushing tube 220, and the air inlet tube 230 balances the air pressure inside and outside the infusion bottle 210, so that the liquid in the infusion bottle 210 can be smoothly discharged through the flushing tube 220, and the urinary catheter 320 is connected through the three-way connector 330 to allow the liquid to be injected into the patient's bladder through the urinary catheter 320. After the bladder is filled, the excess liquid will flow back into the pressure measuring tube 310, and then the height of the liquid in the pressure measuring tube 310 is measured by the pressure measuring ruler 340, so that the bladder pressure can be easily measured, which is convenient for medical staff to use and improves the convenience of detection.

[0029] It should be noted that when arranging the urinary catheter 320, the metal wire 321 is first passed through the urinary catheter 320, and the sealing block 323 blocks the through hole 322, and then the metal wire 321 is bent so that the urinary catheter 320 can adapt to the shape of the patient's urethra, and then the urinary catheter 320 is inserted into the patient's urethra, and then the metal wire 321 is pulled out of the urinary catheter 320, and finally the urinary catheter 320 is connected to the three-way joint 330, so as to facilitate the arrangement of the urinary catheter 320.

[0030] It is understandable that, referring to Figure 2 The sealing block 323 is in the shape of a cylinder, and the connection between the side wall and the end surface of the sealing block 323 is an arc transition. By setting the sealing block 323 in the shape of a cylinder, the shape of the sealing block 323 can match the inner wall of the urinary tube 320, so that the position of the metal wire 321 in the urinary tube 320 can be stabilized, so that the sealing block 323 can seal the through hole 322 to prevent urine from entering through the through hole 322.

[0031] In addition, the connection between the side wall and the end face of the sealing block 323 is an arc transition, so that the outer wall of the sealing block 323 is smooth, so that the metal wire 321 can slide smoothly on the inner wall of the urinary tube 320, thereby improving the smoothness of the movement of the metal wire 321 in the urinary tube 320, facilitating the insertion or extraction of the metal wire 321 from the urinary tube 320, and improving the convenience of operation. In addition, the possibility of the sealing block 323 scratching the urinary tube 320 can be reduced, thereby improving reliability.

[0032] It should be noted that the end of the urinary catheter 320 is sealed, and the through hole 322 is provided on the side wall of the urinary catheter 320, so that when the metal wire 321 is passed through the urinary catheter 320, the sealing block 323 can abut against the end of the urinary catheter 320, which is convenient for medical staff to apply force to insert the urinary catheter 320 into the patient's urethra. In addition, by providing the through hole 322 on the side wall of the urinary catheter 320, when the liquid is discharged from the urinary catheter 320, it is prevented from directly impacting the patient, which can slow down the flow rate of the liquid and improve the patient's use experience.

[0034] It should be noted that the fastener 341 can be a bolt or a screw, as long as it can fix the pressure gauge 340 on the support frame 100, and is not limited here.

[0035] Specifically, refer to Figure 3 The shape of the pressure gauge 340 is an arc, so that the pressure gauge 340 matches the shape of the pressure measuring tube 310. By setting the shape of the pressure gauge 340 to be an arc, the pressure gauge 340 can be attached to the outer wall of the pressure measuring tube 310, so that it is convenient for medical staff to read the pressure gauge 340, reduce errors, and improve the accuracy of detection.

[0036] In addition, by matching the shape of the pressure gauge 340 with the pressure measuring tube 310, the positional shaking of the pressure gauge 340 on the pressure measuring tube 310 can be reduced, the positional stability of the pressure gauge 340 can be improved, the reading can be facilitated, and the accuracy of the detection can be improved.

[0037] It is understandable that, referring to Figure 1The pressure measuring tube 310 is connected with a fixing clamp 350, and the fixing clamp 350 is used to fix the pressure measuring tube 310 to the support frame 100. The fixing clamp 350 is fixedly connected to the support frame 100, and the fixing clamp 350 abuts against the pressure measuring tube 310, so that the fixing clamp 350 can press the pressure measuring tube 310 on the support frame 100, so that the pressure measuring tube 310 can be conveniently fixed on the support frame 100, which is convenient for arranging the position of the pressure measuring tube 310 and improving the convenience of using the bladder pressure measuring device.

[0038] It is understandable that, referring to Figure 1 and Figure 4 The support frame 100 includes a fixed rod 110 and a sliding rod 120. The sliding rod 120 is slidably connected to the fixed rod 110. The sliding rod 120 is connected to a hook 121, and the infusion bottle 210 is installed in the hook 121. The sliding rod 120 is slidably connected to the fixed rod 110 so that the sliding rod 120 can smoothly move along the axial direction of the fixed rod 110, thereby conveniently adjusting the height of the support frame 100. The hook 121 is connected to the sliding rod 120. By setting the hook 121, the infusion bottle 210 can be conveniently installed, which can adapt to different installation positions and improve the convenience of use.

[0039] Specifically, refer to Figure 1 and Figure 4 The fixed rod 110 is provided with a plurality of positioning holes 112 along the axial direction, and the sliding rod 120 is connected with a positioning column 122 along the radial direction. A spring 123 is connected between the positioning column 122 and the sliding rod 120, and the spring 123 is used to drive the positioning column 122 to move radially along the sliding rod 120, so that the positioning column 122 can be inserted into the positioning hole 112. The plurality of positioning holes 112 are arranged at intervals along the axial direction of the fixed rod 110, and the positioning column 122 is arranged radially along the sliding rod 120. The positioning column 122 is slidably connected to the sliding rod 120, and the two ends of the spring 123 respectively abut against the positioning column 122 and the sliding rod 120, and the positioning column 122 is driven by the spring 123 to move in a direction away from the sliding rod 120, so that the positioning column 122 can be easily inserted into the positioning hole 112, so that the position of the sliding rod 120 on the fixed rod 110 can be quickly positioned, and the position of the sliding rod 120 does not need to be locked by a tool, thereby improving the adjustment convenience of the sliding rod 120.

[0040] It is understandable that, referring to Figure 1 The lower end of the support frame 100 is connected with a plurality of rollers 130. The support frame 100 is supported by the plurality of rollers 130 to facilitate the movement of the support frame 100, and there is no need to manually carry the bladder pressure measuring device, thereby reducing labor intensity and improving the convenience and efficiency of detection.
