Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary devices, and in particular to a urethral catheterization towel used for urodynamic examination. Background Art

[0002] Urodynamics is a discipline that studies the dynamic changes of urine during its flow and storage in the urinary tract. It plays a vital role in the diagnosis and treatment of various urinary system diseases. In order to prevent cross infection and protect the patient's unoperated area, a drape is required during urodynamic examination. In clinical practice, ordinary disposable drapes in disinfection packages are routinely used. The main material is a medical plastic film composite non-woven fabric. This drape has good waterproof properties and a relatively smooth surface, which can reduce the friction resistance between the pipe and the drape. It has the following technical defects: 1) The specifications of disposable drapes in conventional disinfection packages are basically fixed, and it is impossible to lay out a sterile operating area according to the patient's body shape, which increases the occurrence 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 urinating autonomously. At this time, the patient often cannot accurately discharge the urine into the urine collection bucket due to the parabola of urination, or accidentally splashes urine on the medical staff, and feels ashamed, and then dares not urinate or tries to control the speed of urination. The results often affect the accuracy of the urodynamic examination results; 3) When conducting a urodynamic examination, it is necessary to insert a bladder pressure measuring tube and a rectal pressure measuring tube into the patient. Each pressure measuring tube has no internal fixing device. Because the ordinary disposable drapes used cannot be fixed by themselves, it is even more impossible to fix the pressure measuring catheter, which can easily lead to the displacement or slippage of the catheter, affecting the detection of various pressure values; 4) Because the patient needs to take the lithotomy position and expose the perineum during urodynamic examination, the ordinary disposable drapes cannot be well fixed to the patient's lower abdomen, which will cause slippage and contaminate the examination site, affecting the smooth progress of the urodynamic examination.

[0003] Therefore, how to design a catheterization drape for urodynamic examination that has good ductility and is suitable for patients of different body shapes, and how to design a catheterization drape for urodynamic examination that prevents urine splashing when patients urinate and increases the accuracy of urodynamic examination results has become an urgent problem to be solved. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention provides a catheterization towel for urodynamic examination to solve at least one of the above technical problems.

[0005] The technical solution of the present invention is: a catheterization drape for urodynamic examination, comprising a drape body, wherein the drape body is a cross-shaped arc block, a through hole is provided in the middle of the cross-shaped arc block, an annular boss is provided between the through hole and the angle between the cross-shaped arc block, the angles of the cross-shaped arc block are connected to the annular boss through pleats, any one of the pleats is a fan-shaped pleat composed of dozens of pleats, and the arc length of the fan-shaped pleat close to the annular boss is smaller than the arc length of the end away from the annular boss.

[0006] The present invention adopts a drape body with a cross-shaped arc block structure. The angle of the cross-shaped arc block and the inner side of the annular boss are both pleated. The pleats are fan-shaped pleats composed of dozens of pleats. The fan-shaped pleats make the surface of the drape have good ductility and are suitable for patients of different body shapes. This solves the technical defect that the specifications of disposable drapes in conventional disinfection packages are basically fixed, and the sterile operation area cannot be laid according to the patient's body shape, which increases the occurrence of infection.

[0025] Embodiment 1: A urethral catheterization towel for urodynamic examination, referring to Figure 1 , including a drape body, the drape body is a cross-shaped arc block, a through hole is provided in the middle of the cross-shaped arc block, an annular boss is provided between the through hole and the angle of the cross-shaped arc block, the angle of the cross-shaped arc block is connected to the annular boss through pleats 1, any one of the pleats 1 is a fan-shaped pleat composed of dozens of pleats, and the arc length of the fan-shaped pleat close to one end of the annular boss is less than the arc length away from the end of the annular boss. The present invention adopts a drape body with a cross-shaped arc block structure, the angle of the cross-shaped arc block and the inner side of the annular boss are both pleated, the pleats are fan-shaped pleats composed of dozens of pleats, the fan-shaped pleats make the surface of the drape have good ductility, suitable for patients of different body shapes, and solves the technical defect that the specifications of disposable drapes in conventional disinfection packages are basically fixed, and the sterile operation area cannot be laid according to the patient's body shape, which increases the occurrence of infection.

[0026] Embodiment 2: Based on Embodiment 1, refer to Figure 2A U-shaped shielding plate 2 is arranged in the through hole of the cross-shaped arc block, and the opening end of the U-shaped shielding plate 2 is exposed on the end surface away from the patient. One opening end of the U-shaped shielding plate 2 is arranged in the horizontal direction, and the other opening end of the U-shaped shielding plate 2 is arranged obliquely downward. The present invention adopts a U-shaped shielding plate arranged in the through hole, and the open end of the U-shaped shielding plate is exposed on the end face away from the patient, which can prevent the patient's urine from splashing onto the medical staff when urinating, reduce the patient's psychological factors when urinating, and thus increase the accuracy of the urodynamic examination results; one open end of the U-shaped shielding plate is arranged in the horizontal direction, and the other open end of the U-shaped shielding plate is arranged obliquely downward, which can drain the urine into the urine collecting bucket, and solves the problem that during the urination period of the urodynamic examination, the patient needs to maintain the lithotomy position and insert the pressure measuring tube while urinating autonomously. At this time, the patient is often unable to accurately discharge the urine into the urine collecting bucket due to the urination parabola, or accidentally splashes the urine onto the medical staff, and feels ashamed, and then dares not to urinate or tries to control the urination speed, which often affects the technical defect of the accuracy of the urodynamic examination results.

[0027] Embodiment 3: Based on Embodiment 2, the two open ends of the U-shaped shielding plate 2 are inferior arc tubes, and the inner arc surfaces of the two inferior arc tubes are close to the through hole. The present invention uses two inferior arc tubes to form the two open ends of the U-shaped shielding plate, which can drain urine into the urine collection bucket, solving the technical defect that during the urination period of urodynamic examination, the patient needs to maintain the lithotomy position and insert the pressure measuring tube while urinating autonomously. At this time, the patient is often unable to accurately discharge urine into the urine collection bucket due to the parabola of urination, or accidentally splashes urine on medical staff.

[0028] Embodiment 4: Based on Embodiment 3, refer to Figure 3 A universal support tube 7 is arranged below the U-shaped shielding plate 2. The universal support tube 7 is a V-shaped structure. One side of the V-shaped structure is fixed to the drape body by sewing cotton cloth, and the other side of the V-shaped structure is installed at the bottom of the other opening of the U-shaped shielding plate 2. The present invention adopts a universal support tube with a V-shaped structure. The universal support tube has a 360° bending and shaping function. One end of the universal support tube is installed at the bottom of the U-shaped shielding plate, and the other end of the universal support tube is sewn and fixed to the drape body by sewing cotton cloth, so that the U-shaped shielding plate has a supporting force and can adjust the opening angle at will, and can drain urine into the urine collection bucket, which solves the technical defect that during the urination period of urodynamic examination, the patient needs to maintain the lithotomy position and insert the pressure measuring tube while urinating autonomously. At this time, the patient is often unable to accurately discharge urine into the urine collection bucket due to the parabola of urination, or accidentally splashes urine on the medical staff.

[0029] Embodiment 5: Based on Embodiment 4, refer to Figure 4Four catheter fixing devices 3 are arranged on the end face of the hole towel body away from the patient. The catheter fixing devices 3 are located on the end face between the annular boss and the through hole. The four catheter fixing devices 3 are located at the four corner points of the rectangle, and any catheter fixing device 3 can be pasted after crossing. The present invention adopts the method of setting the catheter fixing device on the end face of the hole towel body away from the patient. The pasting structure of any catheter fixing device crossing can fix the position of the catheter without compressing the catheter, which can reduce the factors affecting the pressure value detection, and solves the problem that when performing urodynamic examination, the patient needs to be inserted with a bladder pressure measuring tube and a rectal pressure measuring tube. Each pressure measuring tube has no internal fixing device. Because the ordinary disposable hole towel itself cannot be fixed, it is even more impossible to fix the pressure measuring catheter, which easily leads to displacement or slippage of the catheter, affecting the technical defect of each pressure value detection.

[0030] Embodiment 6: Based on Embodiment 5, refer to Figure 5 , Figure 6 The catheter fixing device 3 includes a bottom fixing plate, a U-shaped plate 301 is arranged at one end of the top surface of the bottom fixing plate, the opening of the U-shaped plate 301 faces the middle of the bottom fixing plate, a T-shaped plate 302 is arranged in the middle of the bottom fixing plate, the web of the T-shaped plate 302 faces the side away from the U-shaped plate 301, the flange of the T-shaped plate 302 and the open end of the U-shaped plate 301 are connected to the middle of the top surface of the bottom fixing plate; the closed end of the U-shaped plate 301 is bent toward one side of the T-shaped plate 302, the web of the T-shaped plate 302 is bent toward the opening of the U-shaped plate 301, and the web of the T-shaped plate 302 passes through the opening of the U-shaped plate 301 and is cross-pasted to form an independent space for fixing the catheter. The present invention adopts the method of fixing the flange of the T-shaped piece and the open end of the U-shaped piece on the top surface of the bottom fixing piece, so that the closed end of the U-shaped piece is conveniently bent toward the opening of the U-shaped piece, and the web of the T-shaped piece is passed through the opening of the U-shaped piece and then cross-pasted to form an independent space for fixing the catheter, thereby solving the technical defect that when performing urodynamic examination, a bladder pressure measuring tube and a rectal pressure measuring tube need to be inserted into the patient, and each pressure measuring tube has no internal fixing device, and the ordinary disposable hole towel used cannot be fixed by itself, and now it is even more impossible to fix the pressure measuring catheter, which easily leads to displacement or slippage of the catheter, affecting the detection of various pressure values.

[0031] Embodiment 7: Based on Embodiment 1, Figure 7 , Figure 8 , Fig. 9, the outer ring of the cross-shaped arc block is provided with a bandage 4, a circle of thickened cotton cloth is provided around the outer side of the bandage 4, and a universal bellows 5 is installed inside the cotton cloth.

The four head ends of the cross-shaped arc block all have a 360° bending and shaping function. The bandage can be used in combination to wrap the patient's waist and lower abdomen. The bandage position is fixed by the universal bellows, so that the drape is always kept at the patient's examination site, which solves the technical defect that the patient needs to take the lithotomy position and expose the perineum when performing urodynamic examination, and the ordinary disposable drape cannot be well fixed to the patient's lower abdomen, which will cause slippage, thereby contaminating the examination site and affecting the smooth progress of the urodynamic examination.

[0032] Embodiment 8: Based on Embodiment 7, refer to Fig.10 , Fig.11 The four head ends of the cross-shaped arc block are all provided with Velcro 6, and the two head ends on the same straight line are respectively provided with the hook surface of Velcro 6 and the fur surface of Velcro 6. The present invention adopts that Velcro is provided at the four head ends of the cross-shaped arc block, and the two head ends on the same straight line are respectively provided with the hook surface of Velcro and the fur surface of Velcro. After the patient's waist and lower abdomen are surrounded by a bandage, the hook surface of Velcro is bonded with the fur surface of Velcro to stick the bandage, which can fix the position of the bandage and keep the drape at the patient's examination site at all times, solving the technical defect that the patient needs to take the lithotomy position to expose the perineum during urodynamic examination, and the ordinary disposable drape cannot be well fixed to the patient's lower abdomen, which will cause slippage, thereby contaminating the examination site and affecting the smooth progress of urodynamic examination.

[0033] Embodiment 9. On the basis of embodiment 8, the two adjacent head ends are both provided with a hook surface of Velcro 6, and the hook surface of Velcro 6 is located on the end surface close to the patient; in addition, the two adjacent head ends are both provided with a fur surface of Velcro 6, and the fur surface of Velcro 6 is located on the end surface away from the patient. The present invention adopts that two adjacent head ends are both provided with hook surfaces of Velcro, and the hook surface of Velcro is located on the end surface on the side close to the patient; in addition, two adjacent head ends are both provided with fur surfaces of Velcro, and the fur surface of Velcro is located on the end surface on the side away from the patient, so that the hook surfaces of Velcro and the fur surface of Velcro of the two head ends on the same straight line are not on the same plane. After the waist and lower abdomen of the patient are surrounded by a bandage, the hook surface of Velcro is bonded with the fur surface of Velcro to stick the bandage, which can fix the position of the bandage, so that the drape is always kept at the patient's examination site, which is convenient for the hook surface of Velcro to bond with the fur surface of Velcro, and the drape body can be fixed, thereby solving the technical defect that the patient needs to take the lithotomy position to expose the perineum during urodynamic examination, and the ordinary disposable drape cannot be well fixed on the patient's lower abdomen, which will cause slippage, thereby polluting the examination site and affecting the smooth progress of the urodynamic examination.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
