Description

Be applied to prostate postoperative external pressure hemostasis device of urethral canal

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to be applied to prostate postoperative external pressure hemostasis device of urethral canal pipe.

Background

The prostate is a special gonadal organ of a male, the probability that an old male patient suffers from benign prostatic hyperplasia is high, lower urinary tract symptoms are aggravated after suffering from benign prostatic hyperplasia, and the symptoms of thin urinary line, waiting for urination, difficult urination and the like are embodied in the urination period, so that the life quality of the patient is seriously influenced. Currently, transurethral prostatectomy (TURP) is a conventional standard operation for solving the above diseases, but bladder irrigation needs to be continuously carried out 24 hours after operation to prevent hematuria, catheter blockage and other phenomena so as to avoid causing clinical complications; aiming at the problems, the method adopted clinically is to place the catheter in the urethra conventionally, fill about 50mL of the balloon of the catheter in the bladder with the bladder to realize continuous positive pressure on the neck of the bladder so as to realize compression hemostasis, but the measure still faces the risk of unpredictable bleeding of the prostate wound surface in the perioperative period of placing the catheter in the body, and medical personnel also need to take compression hemostasis measures in the neck of the bladder discontinuously according to the depth of the urine color in the postoperative catheter. At present, the clinical postoperative hemostasis measures are mainly three types:

1. the length of the catheter in the urethra is shortened by binding gauze at the exposed part of the catheter, the water sac compresses the neck of the bladder, the pressure in the wound surface at the prostate urethra part is increased, and the compression hemostasis effect is improved; however, the gauze is easily polluted by bleeding blood and enuresis in the urethra, the loosening and binding process is frequent and complicated, and the skin at the position of the glans penis is easily damaged and ulcerated;

2. the patient is advised to move as early as possible after the operation so as to avoid the risks of thrombus, pneumonia, pressure sore and the like caused by too long time lying in bed, and the relative position of the catheter caused by the movement is not fixed and is easy to cause scabbing and falling off with the prostate wound surface due to too much friction and the like, so that the bleeding risk is aggravated;

3. the exposed part of the catheter is bound or stuck to one side of the lower limb at one side after operation, so that the positive pressure effect on the neck of the bladder in the catheter air bag is increased, the aim of creating compressive pressurization hemostasis for the prostate part of the urethra locally is fulfilled, and the effect of relative displacement caused by sliding of the catheter is prevented; however, the lower limbs of the patient can move freely, in the process of free movement, the patient can change the mobility of the lower limbs autonomously, so that the relative fixing degree in the catheter is influenced, and meanwhile, the catheter is easy to slip from the bladder into the urethra suddenly due to the fact that the patient exerts too hard, and secondary damage is caused to the neck of the bladder.

The utility model discloses to the above-mentioned defect that the hemostasis by compression measure that goes on to the hemorrhage problem of prostate postoperative exists among the prior art, provide a be applied to prostate postoperative external pressure hemostasis device of urethral canal pipe.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problems in the background art, the utility model provides a prostate post-operation external pressure hemostasis device applied to a urethral canal.

A prostate post-operation external pressure hemostasis device applied to a urethral catheter comprises a catheter with an air bag and a fixer for fixing the length of the catheter; the catheter is characterized in that the fixer comprises a glans section and a limit section, wherein the glans section is used for being sleeved outside the glans, the limit section is sleeved outside the catheter, and the glans section and the limit section are mutually separated; the fixer is of an elastic opening-closing type and comprises a left C-shaped ring and a right C-shaped ring, the first end of the left C-shaped ring is movably connected with the first end of the right C-shaped ring through a connecting structure, and the second end of the left C-shaped ring is not connected with the second end of the right C-shaped ring; during the use, hug closely the glans penis outside with the glans penis section, the catheter is cliied to spacing section to the opening angle messenger between rethread left C shape ring first end and the right C shape ring first end to the realization prevents that the relative urethra of catheter from taking place the purpose of displacement.

Furthermore, the connecting structure comprises a left connecting pad with a round hole arranged at the first end of the left C-shaped ring, a right connecting pad with a round hole arranged at the first end of the right C-shaped ring, and a spiral column capable of extending into the round hole, wherein the spiral column is movably connected with the left connecting pad, and the spiral column is movably connected with the right connecting pad; in this way, the spiral column penetrates through the round holes on the left connecting pad and the right connecting pad, and the movable connection of the left C-shaped ring and the right C-shaped ring is realized.
