Description

Technical Field

[0001] The invention relates to the technical field of multi-lumen urinary catheters, in particular to a multi-lumen urinary catheter with temperature and pressure measuring functions. Background Art

[0002] A multi-lumen catheter is a medical device that is mainly used to drain urine and maintain pressure in the bladder. It is usually composed of a catheter and a balloon and has multiple lumens that can be used for different functions, such as urination, infusion of fluids, drainage of urine, etc. When using a multi-lumen catheter, one end needs to be inserted into the bladder through the reproductive organ to draw out urine in the bladder to maintain pressure balance. However, after surgery, a small amount of tissue fragments inside the bladder will block the catheter. In addition, during long-term use, the precipitation formed by minerals, crystals or uric acid crystals in the bladder will also block the catheter, thus affecting the pressure balance in the patient's bladder. After the balloon in the catheter is filled with saline, it is sealed with a rubber cover to prevent the saline from leaking out. However, during use, the patient is active in daily life and the rubber cover may fall off due to friction from clothing or skin, causing the saline to leak out and the catheter to fall out of the bladder.

[0003] Therefore, those skilled in the art provide a multi-lumen urinary catheter with temperature and pressure measurement functions to solve the problems raised in the above background technology. Summary of the invention

However, after surgery, there are a small amount of tissue fragments inside the bladder, which will block the urinary catheter. In addition, during long-term use, the precipitation formed by minerals, crystal substances or uric acid crystals in the bladder will also block the urinary catheter, thereby affecting the pressure balance in the patient's bladder. After the balloon in the catheter is filled with saline, it is sealed with a rubber cover to prevent the saline from flowing out. However, during use, the patient is active in daily life, and the rubber cover may fall off due to friction with clothing or skin, causing the saline to flow out and the catheter to fall out of the bladder.

DETAILED DESCRIPTION

[0018] The embodiment of the present invention provides a multi-lumen urinary catheter with temperature and pressure measurement functions, which solves the following problems: when using the multi-lumen urinary catheter, one end needs to be inserted into the bladder through the reproductive organ to draw out urine in the bladder to maintain pressure balance. However, a small amount of tissue fragments in the bladder after surgery will block the urinary catheter, and during long-term use, the precipitation formed by minerals, crystal substances or uric acid crystals in the bladder will also block the urinary catheter, thereby affecting the pressure balance in the patient's bladder. After the balloon in the catheter is filled with saline, it is sealed with a rubber cover to prevent the saline from flowing out. However, during use, the patient is in a state of daily activity, and the rubber cover may fall off due to friction with clothing or skin, causing the saline to flow out and the catheter to fall out of the bladder. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 - Figure 8 As shown, a multi-lumen urinary catheter with temperature and pressure measuring functions of the present invention comprises a hose 1, a water injection cavity 11 is opened in the inner wall of the hose 1, a drainage cavity 12 is installed inside the hose 1, a flushing cavity 13 is provided on the inner wall of the hose 1 through the outer wall of the drainage cavity 12, a connecting pipe 2 is installed at one end of the hose 1, a water injection pipe 21, a drainage pipe 22 and a flushing pipe 23 are respectively installed on the outer surface of the connecting pipe 2, an anti-falling mechanism 3 is provided on the outer surface of the hose 1 and the inner surface of the water injection pipe 21, a filtering mechanism 4 is provided at the other end of the hose 1, a flushing mechanism 5 is provided on the outer surface of the hose 1 and the outer surface of the flushing pipe 23, and a fixing mechanism 6 is provided on the outer surface of the hose 1.

[0020] According to the above technical solution, the hose 1 is made of rubber, and a water injection cavity 11 is opened in the inner wall of the hose 1.

A circular ring seat 42 is installed at one end of the hose 1, and the other end is installed with the connecting pipe 2. The inner cavity surface of the hose 1 and the outer surface of the drainage cavity 12 form a flushing cavity 13, wherein the water injection cavity 11, the drainage cavity 12 and the flushing cavity 13 are not connected to each other and do not affect each other. At this time, three cavities are formed inside the hose 1, and each cavity plays a different role.

[0021] A further technical solution is that the anti-falling mechanism 3 includes a sealing limit block 31 installed on the inner surface of the water injection pipe 21, a water outlet piece 32 with an axis is slidably installed on the inner surface of the sealing limit block 31, a pushing block 33 is installed on the axial end of the water outlet piece 32 with an axis, a plastic spring 34 is sleeved on the axial part of the water outlet piece 32 with an axis, a water bag 35 is installed on the outer surface of the hose 1, and a pressure plate 36 is attached to the outer surface of the sealing limit block 31.

[0022] The cam 33 is provided with a plurality of holes for sealing the sealing member 31, and the holes for sealing the sealing member 31 are connected to the cam 33. The cam 33 is provided with a plurality of holes for sealing the sealing member 31, and the holes for sealing the sealing member 31 are connected to the cam 33. When the cam 33 is in a state of being stretched, the cam 33 is pressed against the sealing member 31, and the cam 33 is pressed against the sealing member 31. When the cam 33 is in a state of being stretched, the cam 33 is pressed against the sealing member 31, and the cam 33 is pressed against the sealing member 31. When in use, first align the syringe filled with saline with the water inlet hole at the axial end of the shaft water outlet piece 32, then press the syringe so that the push block 33 compresses the plastic spring 34, and the shaft water outlet piece 32 separates from the sealing limit block 31, and the saline can flow out from the hole of the shaft water outlet piece 32, and flow from the water injection chamber 11 to the water bag 35, inflating the water bag 35, thereby fixing the catheter and the bladder, and then retract the syringe, and the plastic spring 34 rebounds to put the shaft water outlet piece 32 back in the sealing limit block 31, so that the hole in the shaft water outlet piece 32 is sealed to prevent saline from leaking. When the water bag 35 is inflated to the maximum value, the pressure value detected by the pressure plate 36 inside the bladder is zero, and the pressure inside the bladder will press the water bag 35, causing the value of the pressure plate 36 to change, thereby detecting the pressure inside the bladder.

[0023] According to a further technical solution, the water injection cavity 11 , the water injection pipe 21 and the water bag 35 are connected.

[0024] According to the above technical solution, the water injection chamber 11 serves as a channel for providing an input of salt water.

[0025] A further technical solution is that the filtering mechanism 4 includes a filter drill bit 41 fixedly installed at the other end of the hose 1, a circular seat 42 is fixedly installed inside the hose 1, a triangular seat 43 is fixedly installed inside the circular seat 42, one end of a rotating shaft 44 rotatably installed on the surface of the triangular seat 43 is rotatably connected to the inner surface of the filter drill bit 41, a filter cage 45 and a turbine blade 46 are rotatably installed on the outer surface of the rotating shaft 44, and a temperature plate 47 is embedded in the outer surface of the filter drill bit 41.

[0026] According to the above technical solution, a strip hole is provided on the surface of the filter drill 41, so that the postoperative tissue and sediment in the bladder can enter between the filter drill 41 and the filter cage 45. One end of the rotating shaft 44 is rotatably connected to the inner surface of the filter drill 41, and the other end is rotatably connected to the triangular seat 43. The filter cage 45 and the turbine blade 46 are fixedly mounted on the rotating shaft 44. The turbine blade 46 is located inside the annular seat 42. When urine flows from the filter cage 45 into the annular seat 42 and then flows out through the drainage cavity 12, the turbine blade 46 is driven to rotate, thereby driving the filter cage 45 to rotate. The filter cage 45 and the filter drill 41 rub against each other, so that the postoperative tissue and sediment can be crushed and transported out. The inner surface of the filter drill 41 and the outer surface of the filter cage 45 are rough surfaces. During use, first, when the pressure inside the bladder is too high, the valve of the drainage tube 22 is opened, and the urine in the bladder will pass through the filter cage 45, the turbine blades 46, the annular seat 42, the drainage cavity 12, and finally flow to the urine bag through the drainage tube 22. When the urine flows from the filter drill bit 41 to the filter cage 45, the postoperative tissue and sediment can be filtered between the filter drill bit 41 and the filter cage 45, and then the urine drives the turbine blades 46 to rotate, thereby driving the filter cage 45 to rotate. The filter cage 45 and the filter drill bit 41 rub against each other to crush the postoperative tissue and sediment, thereby preventing the catheter from being blocked. The temperature sheet 47 is embedded in the outer surface of the filter drill bit 41. The temperature sheet 47 is inside the bladder and can detect the temperature inside the bladder in real time.

[0027] According to a further technical solution, the drainage tube 22 and the drainage cavity 12 are connected to the outside through the grooves and holes opened on the surfaces of the filter drill 41 and the filter cage 45 .

[0028] According to the above technical solution, the drainage cavity 12 is a cavity through which urine flows out.

[0029] According to a further technical solution, the flushing mechanism 5 includes a mounting ring 51 fixedly mounted on the outer surface of the flushing pipe 23, a sealing cover 52 is mounted on the outer surface of the mounting ring 51, a mounting hole 53 is opened on the outer surface of the hose 1, and a one-way valve 54 is mounted inside the mounting hole 53.

[0030] According to the above technical solution, the sealing cover 52 can seal the outlet of the flushing tube 23 to prevent urine from flowing out, the one-way valve 54 further prevents backflow, and the setting of the annular distributed mounting holes 53 expands the range of the spraying; When in use, first prepare a syringe filled with saline solution, then open the sealing cover 52, insert the syringe injection head into the hole at one end of the flushing tube 23, and inject saline solution. The saline solution will pass through the flushing cavity 13 into the one-way valve 54 provided in the mounting hole 53, and will be sprayed out by the one-way valve 54, thereby cleaning the bladder, and the cleaned water will flow out from the filter mechanism 4.

[0031] According to a further technical solution, the flushing tube 23, the flushing cavity 13 and the one-way valve 54 are connected.

[0032] According to the above technical solution, the flushing cavity 13 is a cavity for the saline to enter the bladder.

[0033] According to a further technical solution, the fixing mechanism 6 comprises a rubber sleeve 61 sleeved on the outer surface of the hose 1 , and a protective cover 62 is installed on the outer surface of the rubber sleeve 61 .

[0034] According to the above technical solution, the rubber sleeve 61 can be adjusted in the hose 1, wherein the protective cover 62 can protect the reproductive organs to prevent infection.

[0035] According to a further technical solution, a second rubber sleeve 63 is sleeved on the outer surface of the connecting pipe 2 , and a binding band 64 is installed on the outer surface of the second rubber sleeve 63 .

[0036] According to the above technical solution, the rubber sleeve 63 can be adjusted on the hose 1, and the strap 64 can be tied to the leg for fixing to prevent the urinary catheter from falling off.

[0037] The embodiment of the present invention also provides a multi-lumen urinary catheter with temperature and pressure measuring functions. The specific working principle is as follows: when in use, first align the syringe filled with saline with the water inlet hole at the shaft end of the shaft water outlet piece 32, then press the syringe so that the push block 33 compresses the plastic spring 34, and the shaft water outlet piece 32 separates from the sealing limit block 31, and the saline can flow from the water outlet hole of the shaft water outlet piece 32 to the water injection cavity 11, and then flow from the water injection cavity 11 to the water bag 35, and the water bag 35 is inflated, so that the catheter and the bladder are fixed, and then the syringe is retracted. The plastic spring 34 rebounds and puts the shaft water outlet piece 32 back in the sealing limit block 31, so that the hole in the shaft water outlet piece 32 is sealed to prevent saline from leaking out. When the water bag 35 is inflated to the maximum value, the value of the pressure plate 36 is zero, and the pressure in the bladder will press the water bag 35, so that the value of the pressure plate 36 changes, thereby detecting the pressure inside the bladder; When in use, first, when the pressure inside the bladder is too high, the valve of the drainage tube 22 is opened, and the urine in the bladder passes through the filter cage 45, the turbine blade 46, the annular seat 42, the drainage cavity 12, and finally flows to the urine bag through the drainage tube 22. When the urine flows from the filter drill bit 41 to the filter cage 45, the postoperative tissue and sediment can be filtered between the filter drill bit 41 and the filter cage 45. Then, the urine drives the turbine blade 46 to rotate, thereby driving the filter cage 45 to rotate. The filter cage 45 and the filter drill bit 41 rub against each other, crushing the postoperative tissue and sediment, thereby preventing the catheter from being blocked. The temperature sheet 47 can monitor the temperature inside the bladder in real time. When in use, first prepare the syringe full of saline solution, then open the sealing cover 52, insert the syringe injection head into the hole of the flushing tube 23, inject saline solution, and the saline solution will pass through the flushing cavity 13 into the one-way valve 54 provided in the mounting hole 53, and will be sprayed out by the one-way valve 54, thereby cleaning the bladder, and the cleaned water will flow out from the filter mechanism 4; When in use, rubber sleeve 1 61 can be adjusted in hose 1, wherein protective cover 62 can protect reproductive organs to prevent infection, rubber sleeve 2 63 can be adjusted on hose 1, and strap 64 can be tied on the leg to fix it to prevent the catheter from falling off.
