Description

Urine collection device for spinal cord injury urinary retention

technical field

The utility model relates to a nursing device, in particular to a urine collection device for spinal cord injury urinary retention.

Background technique

Spinal cord injury (SCI) refers to a serious disabling disease caused by various causes of damage to the structure and function of the spinal cord. After SCI, the nerve control link of urination is destroyed, and the detrusor, urethral sphincter, etc. control reflexes. Reduced function, leading to bladder spasm, resulting in urinary retention and urinary incontinence. Neurogenic lower urinary tract dysfunction caused by spinal cord injury is one of the most challenging techniques in the rehabilitation department. Long-term urination disorder can easily induce severe urinary tract infection, damage the function of the upper urinary tract, and lead to uremia and even renal failure . Considerable progress has been made in the care of lower urinary tract dysfunction in patients with spinal cord injury over the past few decades. However, urinary complications remain one of the most serious complications in patients with SCI. Lower urinary tract dysfunction in patients with spinal cord injury presents with a variety of symptoms and signs that change over time. Studies have shown that even in developed countries, the nursing care of patients with spinal cord injury for lower urinary tract dysfunction is a difficult point, because it involves many aspects such as diagnosis, treatment, complication management, follow-up monitoring and patient compliance of lower urinary tract dysfunction . For the diagnosis and evaluation of lower urinary tract dysfunction in patients with spinal cord injury, urodynamic study (UDS) is the most important aspect that cannot be ignored. For the treatment of patients, in addition to intermittent catheterization (intermittent catheterization, IC), it should also include urinary collectors, indwelling catheters, suprapubic cystostomy, reflex voiding, and surgical treatment.

Urinary retention in spinal cord injury refers to the fact that the bladder is full of urine and cannot be discharged normally. According to its medical history and characteristics, it can be divided into two types: acute urinary retention and chronic urinary retention. Painful, often requiring emergency treatment. In the process of patient treatment, a urine collection device is needed. Due to the existence of intravesical pressure, intermittent catheterization is very important. The patient's one-time urination volume should not exceed 400ml, otherwise the pressure in the bladder will drop sharply, and the bladder Internal bleeding or sudden drop in blood pressure.

Especially in patients with spinal cord injury and urinary retention, the peripheral nerves are destroyed, the bladder detrusor muscle is weak, the urethral sphincter continues to contract, the bladder is overfilled, and there is a risk of bladder rupture. Intermittent urinary catheterization devices exist on the market, but the use is complicated and the cost is high. Therefore, how to provide a spinal cord injury urinary retention urine collection device that is easy to use, low-cost and can control the flow rate is a technical problem that needs to be solved.

Utility model content

In view of the above situation, in order to overcome the defects of the prior art, the purpose of this utility model is to provide a urine collection device for urinary retention in spinal cord injury, which can effectively solve the problem of intermittent catheterization of urinary retention in spinal cord injury.

The technical scheme solved by the utility model is a urine collection device for spinal cord injury urine retention, including a urine bag and a catheter. The outlet of the lower end of the tube is placed above the inner bottom of the urine bag, and the catheter is equipped with a control valve near the top of the urine bag. There are airbags connected together, and the catheter is a double-chamber structure composed of an excretion chamber and an inflatable chamber. One end of the excretion chamber is connected to the outlet of the lower end of the catheter, and the other end is connected to the catheter head to form a catheterization channel; One end of the inflatable cavity communicates with an inflatable tube sealed and connected with the outer wall of the urinary catheter, and the other end communicates with an air bag sealed and connected with the catheter to form an inflatable fixed structure.

The utility model is novel and unique in structure, easy to manufacture, low in cost, convenient to use, and good in effect. It can not only facilitate urination, but also collect the discharged urine. It is clean and hygienic, and is very beneficial to the nursing and rehabilitation of urinary retention in spinal cord injury. Good economic and social benefits.

Description of drawings

Fig. 1 is the front view of the structure of the utility model (the figure is the state after the airbag is inflated).

Implementation

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.

As shown in Figure 1, the utility model is a urine retention device for spinal cord injury, including a urine bag and a catheter, the catheter 5 is screwed together with the urine inlet of the urine bag 1 through a threaded joint 3 , the lower end outlet 5-1 of the urinary catheter is placed above the bottom of the urine bag, the catheter 5 is equipped with a control valve 4 near the top of the urine bag, and the outer end of the catheter is provided with a catheter head 8. The urinary catheter at the rear of the urine head 8 is provided with an air bag 7 connected together. The urinary catheter is a double-cavity structure formed by an excretion chamber and an inflatable chamber. One end of the excretion chamber communicates with the outlet 5-1 at the lower end of the catheter. The other end is connected with the catheter head 8 to form a catheterization channel; one end of the inflatable cavity is connected with the inflatable tube 6 that is sealed and connected with the outer wall of the catheter, and the other end is connected with the air bag 7 that is sealed and connected with the catheter , forming an inflatable fixed structure.

In order to ensure the use effect and ease of use, the urine bag 1 is a bag body made of transparent plastic, with a scale 9 showing urine volume on the bag body;

There is a urine outlet pipe 2 on one side of the urine bag 1, and a first screw-on sealing cover 2-1 is arranged on the outlet of the urine outlet pipe 2, so as to facilitate the sealing or opening of the mouth of the urine outlet pipe;

The air inlet of the inflation tube 6 is equipped with a second screw-on sealing cover 6-1, which facilitates the sealing or opening of the inflation tube mouth;

Described catheter 5 is an elastic double-chamber long hollow body made of silica gel;

The catheter head 8 is cylindrical, and the end away from the air bag 7 is spherical, and the center has a through hole communicating with the catheter;

The control valve 4 can adopt the controller on the existing infusion tube (existing technology).

When in use, insert the urinary catheter into the bladder through the catheter head 8 along the urethra, inflate the air bag 7 from the inflation tube 6 to inflate the air bag (as shown in the figure), and fix the catheter in the bladder to prevent slippage. Once there is urine in the bladder, it will be discharged into the urine bag 1 along the excretion cavity and collected. When the urine volume reaches a certain volume, it can be discharged from the urine outlet tube 2. When the urine bag needs to be cleaned (disposable urine can also be used) bag, convenient for timely replacement), the urine bag can be removed through the threaded joint 3 for cleaning. In order to ensure cleanliness and sanitation, the entire device can also be used for one-time use, just like the infusion device, which is convenient, clean and hygienic, and is very beneficial to urination and nursing of spinal cord injury urinary retention.

The utility model can conveniently help the patient to urinate, and is simple and convenient to use. The urine collection device of the utility model has the effect of intermittent catheterization, is easy to produce, and has low cost. Through the control valve, the urine flow speed can be controlled to prevent the patient from urinating. The flow is fast, and the intra-abdominal pressure drops sharply. The amount of rehydration (water) for the patient can also be determined from the color of the collected urine and the amount of urine. It is very beneficial to the nursing of urinary retention of spinal cord injury, is an innovation in nursing equipment of urinary retention of spinal cord injury, and has good economic and social benefits.
