Problems solved by technology

[0003] Spinal cord injury patients generally need to use urinary catheters for a long time, and the catheters are generally clamped when they do not need to urinate during use. However, the existing catheters cannot monitor the internal pressure during use. It also does not have the function of alarm, and it cannot automatically control the clamped urinary catheter to conduct in time to lead out the urine in the bladder of the spinal cord injury patient. After the urinary catheter is placed in the bladder, sometimes the pressure rises and it will reverse If it flows to the kidney, it will lead to renal failure, which is very dangerous; secondly, because the existing catheter cannot monitor the internal pressure during use, it is not convenient for the patient to regularly fill and empty the bladder. Rehabilitation training; in addition, if the spinal cord injury patient needs to go outside to social places, since he is wearing a catheter, he needs to pay attention to the pressure in the catheter at all times, and consider the need to protect the privacy of the spinal cord injury patient, so call the police The way can not make a sound, for this reason, a spinal cord injury patient with a urinary catheter

Embodiment 1

[0056] A kind of catheter for patients with spinal cord injury, such as figure 1 As shown, it includes a catheterization part 1 and a pressure sensing part 2; the pressure sensing part 2 is installed on the catheterization part 1;

[0057] Such as figure 1 As shown, the urinary catheter 1 includes a catheter 4, a solenoid valve 5 and a first connector 10, the solenoid valve 5 is fixedly installed on the catheter 4, and the solenoid valve 5 is close to the bottom of the catheter 4 end, the first connector 10 is integrally connected and arranged on the outer surface of the conduit 4, and the first connector 10 is arranged near the upper end of the conduit 4;

[0058] Such as Figure 1-5 As shown, the pressure sensing part 2 includes a box body 12, a connecting pipe 11, a touch screen 17, a side cover 13, a pressure sensor 20, a first battery 22, and a controller 21. On one end wall of the box body 12 A mounting hole 26 is opened, and the connecting pipe 11 is fixedly installe...

Embodiment 2

[0082] The difference from Example 1 is that a protective layer is also provided on the outer surface of the box body 12, and the protective layer is prepared by the following method:

[0083] Take the following raw materials and weigh them by weight: 22 parts of epoxy resin, 9 parts of calcium carbonate powder, 8 parts of copper oxide powder, 11 parts of acrylic emulsion, 9 parts of titanium dioxide powder, 9 parts of nano-silver powder, 3 parts of alcohol ester twelve, three 2 parts of ethanolamine, 1 part of emulsified silicone oil and 30 parts of ethanol;

[0084] S1. Add the weighed acrylic emulsion, alcohol ester dodeca, triethanolamine, emulsified silicone oil and ethanol into the mixer and stir for 22min at a stirring speed of 500r / min to prepare a mixed solution;

[0085] S2, adding epoxy resin, calcium carbonate powder, copper oxide powder, titanium dioxide powder and nano-silver powder into a pulverizer for pulverization until the particle diameter of the material i...

Embodiment 3

[0091] The difference with embodiment 2 is the preparation of protective layer, and its specific preparation method is as follows:

[0092] Take the following raw materials and weigh them by weight: 25 parts of epoxy resin, 10 parts of calcium carbonate powder, 9 parts of copper oxide powder, 13 parts of acrylic emulsion, 11 parts of titanium dioxide powder, 10 parts of nano-silver powder, 4 parts of alcohol ester twelve, three 3 parts of ethanolamine, 2 parts of emulsified silicone oil and 35 parts of ethanol;

[0093] S1. Add the weighed acrylic emulsion, alcohol ester dodeca, triethanolamine, emulsified silicone oil and ethanol into the mixer and stir for 25min at a stirring speed of 550r / min to prepare a mixed solution;

[0094] S2, adding epoxy resin, calcium carbonate powder, copper oxide powder, titanium dioxide powder and nano-silver powder into a pulverizer for pulverization until the particle diameter of the material is not greater than 100nm, and a mixed powder mate...

Abstract

The invention discloses a urinary catheter for patients with spinal cord injury, which comprises a urinary catheter, a pressure sensing part and a wearing part; the pressure sensing part is installed on the urinary catheter, and the wearing part and the pressure sensing part communication connection. The present invention can monitor the pressure inside the catheter in real time, automatically control the opening of the electromagnetic valve, and timely export the urine in the bladder of the spinal cord injury patient, which can effectively prevent the pressure in the bladder of the spinal cord injury patient from rising, thereby preventing the bladder of the patient from The urine backflows to the kidneys, thereby preventing the occurrence of renal failure in patients with spinal cord injuries, and effectively ensuring the life safety of patients with spinal cord injuries. The sound can effectively protect the privacy of spinal cord injury patients in social places, and is convenient for patients to carry out rehabilitation training on regular filling and regular emptying of their bladders according to the monitored pressure.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a urinary catheter for patients with spinal cord injury. Background technique [0002] The marrow lesion is in the form of a slightly flattened cylinder with a full length and thickness. It is located in the spinal canal. The upper end is connected with the medulla oblongata at the foramen magnum, and the lower end is tapered into a cone, called the conus medullaris. The tip of the cone continues into a filament. It is called the fime terminale, which goes down through the sacral canal and ends at the back of the second coccyx vertebrae. The total length of the adult spinal cord is about 42 to 45 cm. Spinal cord injury often leads to paralysis and incontinence of limbs below the injured segment. [0003] Patients with spinal cord injury generally need to use a urinary catheter for a long time, and the urinary catheter is generally clamped when it is n...
