TECHNICAL FIELD
[0001] The utility model relates to medical auxiliary device technical field, concretely relates to a urethral catheterization drape for urodynamic examination. BACKGROUND
[0002] Urodynamic is the discipline of studying the dynamic changes of urine flow and storage in the urinary tract. It plays a crucial role in the diagnosis and treatment of various urinary system diseases. To prevent cross infection and protect the non-operated area of the patient, a drape is needed during urodynamic examination. The conventional disposable drape in the disinfection package is commonly used in clinical practice, and the main material is medical plastic film composite non-woven fabric. This drape has good waterproofness, and its surface is relatively smooth, which can reduce the frictional resistance between the pipeline and the drape. However, it has the following technical defects: 1) The size of the disposable drape in the conventional disinfection package is basically fixed, which cannot lay a sterile operating area according to the body type of the patient, increasing the incidence of infection; 2) During the urination period of urodynamic examination, the patient needs to maintain the lithotomy position and insert the pressure measuring tube while performing self-urination. At this time, the patient often cannot accurately discharge urine into the urine collection bucket due to the reason of urination parabola, or accidentally splashes urine on the medical staff, feels ashamed, and then dare not to urinate or try to control the speed of urination, which often affects the accuracy of the urodynamic examination results; 3) During the urodynamic examination, the patient needs to be inserted with a bladder pressure measuring tube and a rectal pressure measuring tube, and each pressure measuring tube has no internal fixing device. Since the commonly used disposable drape itself cannot be fixed, it is now impossible to fix the pressure measuring catheter, which easily leads to the displacement or slipping of the catheter, affecting the detection of each pressure value; 4) Since the patient needs to take the lithotomy position during the urodynamic examination, the perineum is exposed, and the ordinary disposable drape cannot be well fixed on the lower abdomen of the patient, which will cause slipping and further contaminate the examination site, affecting the smooth progress of the urodynamic examination.
[0003] Therefore, how to design a urethral catheterization drape for urodynamic examination with good ductility and suitable for patients of different body types, and how to design a urethral catheterization drape for urodynamic examination that prevents urine splashing during urination and increases the accuracy of urodynamic examination results, have become urgent problems to be solved. UTILITY MODEL CONTENT
[0004] In view of the problems existing in the prior art, the utility model provides a urethral catheterization drape for urodynamic examination to solve at least one of the above technical problems.
[0005] The utility model discloses a technical scheme is: a catheterization for urodynamic examination, including the hole shroud body, the hole shroud body is cross -shaped arc block, and the middle part of cross -shaped arc block is provided with the through -hole, and the included angle between through -hole and cross -shaped arc block is provided with annular boss, and the included angle of cross -shaped arc block is all connected annular boss through pleat, and arbitrary one pleat is by the fan -shaped pleat of tens of pleats, and the arc length of fan -shaped pleat near annular boss one end is less than the arc length of fan -shaped pleat far from annular boss one end.
[0006] The utility model discloses the hole shroud body of cross -shaped arc block structure, and the included angle of cross -shaped arc block and annular boss inboard all have done pleat design, and the fan -shaped pleat of tens of pleats, and the fan -shaped pleat makes the hole shroud surface have good ductility, is suitable for the patient of different body shape, has solved the disposable hole shroud specification in the conventional disinfection bag, and the sterile operation area of laying cannot be according to the body of patient, has increased the technical defect of infection occurrence.
[0007] Preferably, the through hole of the cross-shaped arc block is provided with a U-shaped shielding plate, one open end of the U-shaped shielding plate is arranged along the horizontal direction, and the other open end of the U-shaped shielding plate is arranged obliquely downward.
[0008] The utility model discloses the U-shaped shielding plate is arranged in the through -hole, and the open end of U-shaped shielding plate exposes the side end face far from patient, can prevent the urine splashing to medical staff when patient urinates, reduces the psychological factor of patient when urinating, thereby increases the accuracy of urodynamic examination result;One open end of the U-shaped shielding plate is arranged along the horizontal direction, and the other open end of the U-shaped shielding plate is arranged obliquely downward, which can drain urine into the urine collection barrel, solving the technical defect that the patient needs to keep lithotomy position and insert the pressure measuring tube while urinating during urodynamic examination, at this time, the patient often cannot accurately discharge urine into the urine collection barrel due to the reason of urine parabolic, or accidentally splashes urine on the medical staff, feels ashamed, and then dare not urinate or try to control the speed of urination, which often affects the accuracy of urodynamic examination result.
[0009] Preferably, the side end face of the hole shroud body far from the patient is provided with a plurality of catheter fixing devices, and the catheter fixing device is located on the end face between the annular boss and the through hole;The catheter fixing device includes a bottom fixing sheet, one end of the top surface of the bottom fixing sheet is provided with a U-shaped sheet, the opening of the U-shaped sheet faces the middle part of the bottom fixing sheet, the middle part of the bottom fixing sheet is provided with a T-shaped sheet, the web of the T-shaped sheet faces away from one side of the U-shaped sheet, and the flange of the T-shaped sheet and the open end of the U-shaped sheet are connected with the middle part of the top surface of the bottom fixing sheet;The closed end of the U-shaped sheet is bent towards one side of the T-shaped sheet, the web of the T-shaped sheet is bent towards the opening of the U-shaped sheet, and the web of the T-shaped sheet is crossed and pasted after passing through the opening of the U-shaped sheet, forming an independent space for fixing the catheter.
[0010] This invention employs a catheter fixation device on the end face of the drape body away from the patient. The catheter fixation device includes a bottom fixing piece, and the flange of a T-shaped piece and the open end of a U-shaped piece are fixed on the top surface of the bottom fixing piece. This facilitates the closed end of the U-shaped piece bending towards the opening of the U-shaped piece. The web of the T-shaped piece passes through the opening of the U-shaped piece and is cross-attached, forming an independent space for fixing the catheter. This solves the technical defect that when performing urodynamic examinations, it is necessary to insert bladder manometry tubes and rectal manometry tubes into the patient. Each manometry tube lacks an internal fixing device, and ordinary disposable drapes themselves cannot be fixed, let alone manometry tubes. This easily leads to catheter displacement or slippage, affecting the detection of various pressure values. Attached Figure Description
