Description

A urinary catheter with a pressure sensor

technical field

The utility model belongs to the technical field of medical devices, in particular to a urinary catheter with a pressure sensor.

Background technique

With the continuous development of my country's economy, the high incidence of cerebrovascular disease, and the brain and spinal cord injuries caused by traffic accidents, the number of patients with clinical neurogenic urination disorders is increasing. However, due to insufficient monitoring of intravesical pressure, the patient suffers from renal damage caused by urine reflux or prolonged indwelling of the urinary catheter, resulting in the patient's continuous bladder contraction and insufficient relaxation, resulting in an extreme reduction in bladder capacity and loss of the original bladder storage function, making the patient even Long-term chronic urinary incontinence after removal of the urinary catheter. It can cause a great decline in the quality of life of patients, and even lead to severe urinary tract infection or kidney damage.

Urinary catheterization is widely used in clinical practice. It is necessary for coma, urinary incontinence, lower abdominal and pelvic surgery, urinary retention, local drug perfusion for bladder tumors, heart failure and critically ill patients to accurately record urine output. In addition, the placement of the catheter should keep the perineal part dry and clean to avoid local skin irritation with urine. However, in clinical practice, due to the poor fit between the balloon at the front end of the catheter and the bladder neck, urine often leaks from the side of the catheter after placement, which affects the accurate recording of urine volume. At the same time, the perineum is partially dry and clean. will be affected, and local skin irritation is inevitable.

In addition, the Chinese patent publication number is CN108904958A, and the name of the invention is a urinary catheter, including a head for extending into the bladder and a tail placed outside the bladder, the head is provided with a urination port, and the Said tail is provided with a catheter communicating with said urination port, a balloon is provided at the rear end of the head, a diversion tube communicating with said balloon is provided at said tail, and a The outer wall is provided with folds. However, the existing urinary catheters still have long-term indwelling catheters that are usually opened regularly in clinical practice. Some rehabilitation departments will use urodynamic testing to observe the patient's immediate bladder capacity and sphincter function. The volume situation does not respond; therefore, neither the doctor nor the patient can understand the changes in the intra-vesical pressure during the day, and cannot fundamentally prevent the complications caused by the neurogenic bladder.

In view of this, it is very necessary to invent a urinary catheter with a pressure sensor.

Compared with the prior art, the utility model has the following beneficial effects: the pressure sensor has a diameter of 3 mm, a thickness of 0.1-0.2 mm, good flexibility, can effectively fit the outer wall of the catheter, and effectively measure the pressure on the contact surface; The range is 0.1-100N, which can cover the effective range of the currently known intravesical pressure range; when in use, the nurse will indwell catheterize the patient according to the routine operation procedure of the catheter, and the testable test on the computer terminal and the mobile terminal can display the real-time intravesical pressure. The alarm range can be set according to the actual situation of the patient to remind the physician and the patient to take necessary medical or nursing measures; the pressure sensor can transmit the intravesical pressure data in real time, and guide the physician and the patient to open the urinary catheter in a timely manner according to the intravesical pressure. Catheterization, as far as possible to retain the original circadian rhythm of bladder diastolic and contraction, can prevent excessive pressure in the bladder to cause urine reflux and cause kidney damage, and can also prevent long-term low pressure in the bladder from causing bladder contracture, and finally losing the function of diastolic and urination; The device is low in cost and can continuously observe dynamic data, which is an important improvement on the method of artificially estimating the regular opening of the urinary catheter currently commonly used in clinical practice.
