Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a bladder pressure measuring device. Background Technology

[0002] Measuring intravesical pressure is a method for diagnosing certain diseases. Since the bladder is an intra-abdominal structure, changes in pressure within the bladder can reflect changes in intra-abdominal pressure. Therefore, bladder pressure has a high correlation with indirectly measured intra-abdominal pressure and is considered the "gold standard" for indirect measurement of intra-abdominal pressure in clinical practice. Monitoring bladder pressure is of great significance for the treatment of critically ill patients.

[0003] According to Chinese patent publication document CN214761110U, a bladder pressure measuring device is proposed, including a pressure measuring tube body. The outer wall of the pressure measuring tube body is provided with a scale. The bottom of the pressure measuring tube body is provided with a first three-way switch. A urinary catheter is connected to the left side of the first three-way switch, and a urine bag connecting tube is provided to the right side of the first three-way switch.

[0004] Although this patent can achieve the function of bladder pressure measurement, in actual use, the two three-way switches of this patent mainly rely on the operating experience of medical staff for control, so it has strong limitations. Some people who are not familiar with this patent may not be able to perform bladder pressure measurement with this device. Summary of the Invention

[0005] In order to overcome the shortcomings of existing devices that mainly rely on the operating experience of medical staff for control and have strong limitations, this invention provides a bladder pressure measurement device.

[0008] As an improvement to the above solution, the switching mechanism includes a connecting rod, a rack, a sensor-assisted push rod, a gear, and a buoyancy rod. The sensor-assisted push rod is fixedly mounted on the mounting base and is electrically connected to the integrated controller.

[0009] As an improvement to the above solution, a control mechanism is also included. The control mechanism includes a push rod, a push block, a connecting ring, a push button switch, and an electric push rod. The push rod is rotatably connected to the switching valve, and the push block is rotatably connected to the pressure measuring tube. The push block is rotatably connected to the push rod, and the connecting ring is fixedly connected to the pressure measuring tube. A push button switch for controlling electronic valve one and electronic valve two is fixedly installed on the connecting ring. The push button switch is electrically connected to the integrated controller, and it will abut against the push button switch when the push block rotates. An electric push rod is fixedly connected to the connecting ring, and the electric push rod is electrically connected to the integrated controller. The telescopic rod of the electric push rod is fixedly connected to the cover.

[0010] As an improvement to the above solution, a fixing component is also included. The fixing component includes a mounting bracket, a motor, and an electric clamp. The mounting bracket is fixedly connected to the pressure measuring tube, and the motor for driving is fixedly mounted on the mounting bracket. An electric clamp for connecting the device to the bed is mounted on the output shaft of the motor.

[0011] As an improvement to the above solution, a vertical monitoring component is also included. The vertical monitoring component includes an iron block, an infrared transmitter, and an infrared receiver. The iron block for positioning is fixedly suspended on the mounting bracket. An infrared transmitter for emitting infrared rays is fixedly installed on the bottom surface of the iron block. An infrared receiver is fixedly installed on the mounting base. The infrared receiver is located directly below the infrared transmitter and is electrically connected to the integrated controller.

[0012] As an improvement to the above solution, it also includes an electronic three-way tube and a negative pressure collection bottle. The electronic three-way tube is fixedly connected to the pressure measuring tube, the electronic three-way tube is electrically connected to the integrated controller, the electronic three-way tube is fixedly connected to the negative pressure collection tank, and the negative pressure collection bottle is fixedly connected to the electronic three-way tube.

[0013] As an improvement to the above solution, a one-way valve is also included, with a one-way valve for controlling the gas flow direction fixedly installed on the connecting pipe.

[0014] As an improvement to the above solution, it also includes a piston tube, a piston rod, a gas guide tube, an expansion air bag, a connecting ring, a piston rod that is slidably connected inside the piston tube, a piston rod that is fixedly connected to the cover, a gas guide tube that is fixedly connected to the piston tube, an expansion air bag that is fixedly installed on the liquid guide tube, and the other end of the gas guide tube that is fixedly connected to the expansion air bag.

[0015] As an improvement to the above solution, an impact mechanism is also included. The impact mechanism includes a contact block, a counterweight ring, friction rollers, protrusions, a slide, a return spring, and an impact rod. The contact block is fixedly installed on the top rod. The pressure measuring tube is provided with a slidable counterweight ring that abuts against the contact block. The counterweight ring is provided with two friction rollers that can roll along the outer wall of the pressure measuring tube. The two friction rollers are provided with multiple protrusions along the circumference. The slide is symmetrically and slidably connected to the counterweight ring. The two slides are provided with return springs between the counterweight ring and the two slides. When the friction rollers rotate, the protrusions will abut against the slides on the same side in sequence. The two slides are fixedly installed with impact rods in the direction of the pressure measuring tube, and the impact rods abut against the pressure measuring tube.

[0016] The beneficial effects of this invention are: 1. This invention first removes air from the device through a negative pressure collection tank to prevent air in the pipeline from affecting the bladder pressure measurement results. Then, the flowing physiological saline drives the buoyancy rod in the negative pressure collection tank to move upward. During the upward movement of the buoyancy rod, the switch valve is closed by the cooperation of the rack and pinion, and the top block contacts the button switch to open the electronic valve and the cover, thereby starting the bladder pressure measurement for the patient. This realizes the automated pressure measurement work and increases the universality of this device.

[0017] 2. The present invention moves the piston rod upward along the piston tube when the cover moves upward, thereby injecting the air in the piston tube into the expansion bladder through the air guide tube. This causes the expansion bladder to expand synchronously when the pressure of the patient's bladder is measured, thus ensuring the stability of the connection between the drainage tube and the patient's bladder and preventing the drainage tube from detaching.

[0018] 3. In this invention, the friction rollers roll as the counterweight ring slides down the pressure measuring tube, thereby using the intermittent push of the protrusion to move the slide. Under the elasticity of the return spring, the slide drives the impact rod to strike the pressure measuring tube, thereby dispersing the air bubbles adhering to the inner wall of the pressure measuring tube and ensuring the accuracy of the pressure measurement.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0033] Example: A bladder pressure monitoring device, such as Figures 1-4 As shown, the device includes a pressure measuring tube 1, a scale 2, a mounting base 3, an integrated controller 301, a connecting tube 4, a switch valve 401, a negative pressure collection tank 5, a guide tube 6, an electronic valve 601, a cover 7, a connecting tube 8, an electronic valve 801, a saline tank 9, and a switching mechanism.

The mounting base 3 is bolted to the lower part of the pressure measuring tube 1, and the integrated controller 301 is bolted to the front of the mounting base 3. A connecting tube 4 is sealed to the lower right side of the pressure measuring tube 1, and a switch valve 401 is rotatably mounted on the connecting tube 4. The other end of the connecting tube 4 is sealed to the negative pressure collection tank 5, which collects the air and saline solution used for air removal during the initial state of the device. The negative pressure collection tank 5 is fixedly connected to the mounting base 3. The lower left side of the pressure measuring tube 1 is sealed with a guide tube 6. The guide tube 6 is made of a retractable flexible hose, which facilitates the connection of the guide tube 6 to the patient's bladder. The left end of the guide tube 6 is bolted with an electronic valve 601, which is electrically connected to the integrated controller 301. The top of the pressure measuring tube 1 is slidably connected with a cover 7. The upper right side of the pressure measuring tube 1 is sealed with a connecting tube 8. The connecting tube 8 is bolted with an electronic valve 801. The other end of the connecting tube 8 is sealed with a saline tank 9. When the electronic valve 801 is opened, the saline in the saline tank 9 will flow into the pressure measuring tube 1 through the connecting tube 8. The mounting base 3 is equipped with a switching mechanism for controlling the switching valve 401.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, the switching mechanism includes a connecting rod 1001, a rack 1002, a sensor-assisted push rod 1003, a gear 1004, and a buoyancy rod 1005. A sensor-assisted push rod 1003 is welded to the center of the top surface of the mounting base 3. The connecting rod 1001 is fixedly connected to the telescopic rod of the sensor-assisted push rod 1003. The right end of the connecting rod 1001 is bolted to the buoyancy rod 1005. The buoyancy rod 1005 is located inside the negative pressure collection tank 5, and the buoyancy rod 1004... 005 is slidably connected to the negative pressure collection tank 5. When the saline solution in the negative pressure collection tank 5 reaches a certain height, it will drive the buoyancy rod 1005 to move upward through buoyancy. The left end of the connecting rod 1001 is connected to the rack 1002 by bolts. The left side of the switch valve 401 is connected to the gear 1004 by bolts. The gear 1004 and the rack 1002 mesh with each other. When the rack 1002 moves upward, it will drive the switch valve 401 to rotate through the gear 1004.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a control mechanism, which includes a push rod 1101, a push block 1102, a connecting ring 1103, a push button switch 1104, and an electric push rod 1105. The push rod 1101 is rotatably connected to the switch valve 401, and the push block 1102 is rotatably connected to the upper right side of the pressure measuring tube 1. The push block 1102 is rotatably connected to the upper end of the push rod 1101. The upper part of the pressure measuring tube 1 is bolted to the connecting ring 1103, and the bottom right side of the connecting ring 1103 is bolted to the bottom surface. There is a push-button switch 1104, which is electrically connected to the integrated controller 301. When the top block 1102 rotates, it will abut against the push-button switch 1104. The top surface on the left side of the connecting ring 1103 is connected to an electric push rod 1105 by bolts. The electric push rod 1105 is electrically connected to the integrated controller 301. The telescopic rod of the electric push rod 1105 is connected to the cover 7 by bolts. The integrated controller 301 will use an electrical signal to cause the electric push rod 1105 to open the cover 7 upward.

[0036] like Figure 1 and Figure 7 As shown, it also includes a fixing component, which includes a mounting bracket 1201, a motor 1202, and an electric clamp 1203. The mounting bracket 1201 is bolted to the middle of the back of the pressure measuring tube 1. The motor 1202 is bolted to the back of the mounting bracket 1201. The motor 1202 is electrically connected to the integrated controller 301. The electric clamp 1203 is mounted on the output shaft of the motor 1202. The integrated controller 301 will start the motor 1202 through an electrical signal to drive the electric clamp 1203 to clamp and fix the bed.

[0037] like Figure 1 and Figure 7As shown, it also includes a vertical monitoring component, which includes an iron block 1301, an infrared transmitter 1302, and an infrared receiver 1303. The iron block 1301 is suspended from the bottom surface of the mounting bracket 1201 by bolts, and the infrared transmitter 1302 is mounted on the bottom surface of the iron block 1301 by bolts. Under the action of gravity, the iron block 1301 will keep the infrared transmitter 1302 perpendicular to the ground. The infrared receiver 1303 is mounted on the back of the mounting base 3 by bolts. The infrared receiver 1303 is located directly below the infrared transmitter 1302. The infrared receiver 1303 will monitor the installation status of the pressure measuring tube 1. The infrared receiver 1303 is electrically connected to the integrated controller 301.

[0038] like Figure 1 and Figure 8 As shown, it also includes an electronic three-way tube 1401 and a negative pressure collection bottle 1402. The bottom of the pressure measuring tube 1 is sealed to the electronic three-way tube 1401. The electronic three-way tube 1401 is electrically connected to the integrated controller 301. The right end of the electronic three-way tube 1401 is sealed to the bottom surface of the negative pressure collection tank 5. The bottom end of the electronic three-way tube 1401 is sealed to the negative pressure collection bottle 1402. The negative pressure collection bottle 1402 will collect the physiological saline in the patient's bladder, the pressure measuring tube 1, and the negative pressure collection tank 5.

[0039] like Figure 1 and Figure 3 As shown, it also includes a one-way valve 15. The one-way valve 15 is installed on the connecting pipe 4 by bolts. The one-way valve 15 will prevent the air in the negative pressure collection tank 5 from flowing back.

[0040] like Figure 1 and Figure 9 As shown, it also includes a piston tube 1601, a piston rod 1602, a venting tube 1603, and an expansion airbag 1604. The piston tube 1601 is fixedly installed on the left side of the connecting ring 1103. The piston rod 1602 is slidably connected to the inner bottom of the piston tube 1601. The upper end of the piston rod 1602 is fixedly connected to the bottom surface of the cover 7. The venting tube 1603 is fixedly connected to the upper part of the piston tube 1601. The expansion airbag 1604 is fixedly installed on the left end of the liquid guiding tube 6. The other end of the venting tube 1603 is fixedly connected to the expansion airbag 1604.

[0041] like Figure 1 , Figure 10 , Figure 11 and Figure 12As shown, it also includes an impact mechanism, which includes an abutment block 1701, a counterweight ring 1702, a friction roller 1703, a protrusion 1704, a slide 1705, a return spring 1706, and an impact rod 1707. The abutment block 1701 is fixedly installed on the upper part of the push rod 1101. The upper part of the pressure measuring tube 1 is provided with a counterweight ring 1702 that can slide up and down. The counterweight ring 1702 abuts against the abutment block 1701. The inner left and inner right parts of the counterweight ring 1702 are respectively provided with friction rollers that can roll along the outer side wall of the pressure measuring tube 1. Two friction rollers 1703 are symmetrically provided with three protrusions 1704 along the circumference on the left and right sides respectively. A slide 1705 is symmetrically connected to the counterweight ring 1702. A return spring 1706 is provided between the two slides 1705 and the counterweight ring 1702 respectively. When the friction rollers 1703 rotate, the protrusions 1704 will abut against the slides 1705 on the same side in turn. Impact rods 1707 are fixedly installed on the upper part of the two slides 1705 in the direction of the pressure measuring tube 1 respectively. The impact rods 1707 abut against the pressure measuring tube 1.

[0042] When bladder pressure measurement is required, the integrated controller 301 first starts the motor 1202, which drives the electric clamp 1203 to clamp and fix the bed, thus securing the device to the bed. Simultaneously, the infrared transmitter 1302 emits infrared rays to the infrared receiver 1303. The iron block 1301, through gravity, keeps the infrared transmitter 1302 perpendicular to the bottom surface. The infrared receiver 1303 transmits the position of the pressure measuring tube 1 to the integrated controller 301 in real time via electrical signals, ensuring the vertical placement of the pressure measuring tube 1 and guaranteeing the accuracy of the pressure measurement results. Then, the left end of the fluid guide tube 6... The end is connected to the patient's bladder. At this time, electronic valve 601 is closed, switch valve 401 is open, and electronic three-way tube 1401 is closed. The negative pressure in the negative pressure collection tank 5 will draw air out of the pressure measuring tube 1 and the guide tube 6, and prevent backflow of air in the negative pressure collection tank 5 through the one-way valve 15, thereby expelling the air in the pressure measuring tube 1 and the guide tube 6, thus ensuring the accuracy of bladder pressure measurement. Then, the bladder pressure measurement function is activated by the integrated controller 301. The integrated controller 301 will open electronic valve 801, and the saline in the saline tank 9 will first flow into the negative pressure collection tank 5 along the pressure measuring tube 1.

[0043] When the saline solution in the negative pressure collection tank 5 rises to be level with the buoyancy rod 1005, the saline solution will cause the buoyancy rod 1005 to move upward through buoyancy. The buoyancy rod 1005 will push the connecting rod 1001 upward. After sensing the movement, the integrated controller will activate the induction assist push rod 1003 to assist the connecting rod 1001 to move upward, thereby driving the rack 1002 to move upward synchronously. The rack 1002 will drive the gear 1004 meshing with it to rotate clockwise. The gear 1004 will drive the switch valve 401 to rotate synchronously, thereby closing the connecting pipe 4, and the saline solution will stop flowing into the negative pressure collection tank 5.

[0044] As the switching valve 401 rotates clockwise, it drives the push rod 1101 to move upward. The push rod 1101 then pushes the push block 1102 to rotate upward simultaneously. The push block 1102 then actuates the push button switch 1104. The push button switch 1104 transmits an electrical signal to the integrated controller 301, which then activates the electric push rod 1105. The electric push rod 1105 opens the cover 7 upward, allowing the pressure measuring tube 1 to communicate with the atmosphere. As the cover 7 moves upward, it drives the piston rod 1602 to move upward along the piston tube 1601. The piston tube 1601 is activated, thereby injecting air from the piston tube 1601 into the inflatable balloon 1604 through the air delivery tube 1603. The inflatable balloon 1604 will inflate, thus ensuring the stability of the connection between the fluid delivery tube 6 and the patient's bladder. At the same time, the integrated controller 301 will close the electronic valve 801 and open the electronic valve 601, thereby opening the fluid delivery tube 6. The saline solution in the pressure measuring tube 1 will flow into the patient's bladder through the fluid delivery tube 6. When the saline solution in the pressure measuring tube 1 stops decreasing, the height of the saline solution level from the zero point can be read according to the scale 2 on the pressure measuring tube 1, which is the bladder pressure.

[0045] As the push rod 1101 pushes the push block 1102 upward, the push rod 1101 will drive the abutment block 1701 to disengage from the counterweight ring 1702. Under the action of gravity, the counterweight ring 1702 will slide down along the pressure measuring tube 1, and the two friction rollers 1703 will roll. The protrusion 1704 will push the slide 1705 on the same side in turn to move away from each other. When the protrusion 1704 is no longer in contact with the slide 1705, the elasticity of the return spring 1706 will cause the slide 1705 to drive the impact rod 1707 to impact the outer wall of the pressure measuring tube 1, thereby realizing intermittent vibration of the pressure measuring tube 1, thereby dispersing the air bubbles adhering to the inner wall of the pressure measuring tube 1, and thus ensuring the accuracy of pressure measurement.

[0046] After the bladder pressure test is completed, the electronic three-way tube 1401 is activated by the integrated controller 301. The negative pressure in the negative pressure collection bottle 1402 will draw the saline solution from the patient's bladder, the pressure measuring tube 1 and the negative pressure collection tank 5 into the negative pressure collection bottle 1402 for centralized collection, thus completing the entire bladder pressure test process.
