DETAILED DESCRIPTION
[0016] The specific embodiment of the present application is described below with reference to the accompanying drawings, which are used to further explain the constitution of the present application.
[0017] Example 1
[0018] The urethral traction device of the present embodiment, as shown in the accompanying drawings, comprises a traction frame and a fixator, wherein the traction frame is composed of a first telescopic rod 12, a second telescopic rod 11 and a third telescopic rod 10 connected vertically in sequence, one end of the first telescopic rod 12 is provided with a first pulley 3, the other end of the first telescopic rod 12 is connected with one end of the second telescopic rod 11 vertically, the other end of the second telescopic rod 11 is connected with the third telescopic rod 10 vertically, the top end of the third telescopic rod 10 is provided with a second pulley 5, the third telescopic rod 10 is fixedly connected with the fixator 6 through a bridge plate 9, and the fixator 6 is provided with a third pulley 7 on the side surface. Figure 1 Figure 2 The first telescopic rod 12, the second telescopic rod 11 and the third telescopic rod 10 in the present embodiment are all made of 304 stainless steel square tubes, the outer sleeve tube is 25*25 mm in size and 2 mm in wall thickness, and the inner sleeve tube is 20*20 mm in size and 2 mm in wall thickness, and the telescopic rod length is fixed by M6*12 screws.
[0019] The first pulley 3, the second pulley 5 and the third pulley 7 are all 1.2-inch V-shaped pulleys.
[0020] The end of the first telescopic rod 12 provided with the first pulley is also provided with a support frame 2, which is used to support a quilt, and the support frame 2 is composed of a groove base 2-1 and a support rod 2-2, the first pulley 3 is installed in the groove of the groove base 2-1, the height of the first telescopic rod 12 is adjusted to adjust the reasonable angle of the traction rope 4 and the traction position, the quilt is placed on the support frame 2, which can not only keep the patient warm and protect privacy, but also prevent the quilt from being pressed on the traction rope to change the traction weight.
[0021] The groove base 2-1 of the support frame is provided with a protractor 1 on the outside, the angle of the traction rope 4 and the horizontal direction is measured by the protractor 1, and the height of the first telescopic rod 12 is adjusted to select the best traction angle of the traction rope 4.
[0022] The groove base 2-1 of the support frame is provided with a protractor 1 on the outside, the angle of the traction rope 4 and the horizontal direction is measured by the protractor 1, and the height of the first telescopic rod 12 is adjusted to select the best traction angle of the traction rope 4.
[0023] The fixture 6 is U-shaped, measuring 20 x 15 x 5 cm. The width of the U-shaped groove matches the thickness of the footrest. The fixture material is 4 mm thick, and the thicker wall prevents deformation. It is fixed to the footrest with M8 x 50 screws, ensuring a secure fit.
[0024] When using the urethral traction device of this embodiment, the holder is first secured to the foot of the bed, and the traction frame is extended above the bed. The lengths of the second and third telescopic rods are adjusted according to the user's height, and the lengths are selected and fixed appropriately. The required height of the top of the first pulley is calculated using the tan45° formula based on the traction position of the indwelling urinary catheter, and the first telescopic rod is adjusted to the appropriate length and fixed accordingly. A traction rope is attached to the end of the indwelling urinary catheter and is led out of the bed through the first, second, and third pulleys, in sequence. A traction object is connected to the end of the traction rope, and the weight of the traction object is used to pull the indwelling urinary catheter. The tension carried by the traction rope is passed through the three pulleys to change the direction of the force without changing the magnitude of the force. The parallel pulleys ensure that the traction rope extends out of the bed, preventing the traction object from contacting the bed, thus providing accurate and stable traction.
[0025] The traction rope of this embodiment also adopts the medical willow belt used in the prior art, and is fastened by the surgeon to the lower part of the air valve and the excreta cone interface of the urinary catheter using a surgical square knot (flat knot).
[0026] When using the urethral traction device, the traction effect is best when the pulled part and the three pulley groove positions (i.e. the longitudinal axes of the three telescopic rods) are in the same vertical plane. If the patient needs to change position or turn over, the vertical plane formed by the three telescopic rods can be used as a reference. The traction part can be offset to the left or right by no more than 60 degrees to ensure the traction effect. It will neither affect the patient's normal turning activities nor cause unnecessary discomfort or infection.
[0027] Cleaning and disinfection of urethral traction devices should be performed in accordance with the "Standard for Cleaning and Disinfection of Surfaces in Medical Institutions" (WS / T512-2025) and the "General Requirements for Disinfectants for Medical Devices" (GB27949-2020). Urethral catheter care should be performed in accordance with the "Guidelines for Care of Indwelling Urethral Catheters" and other relevant documents.
[0028] The protection scope of the present invention is not limited to the above embodiments. All urethral traction devices with the same or equivalent technical solutions and structures as the present invention, and urethral traction devices with the same technical solutions and principles as the present invention, fall within the protection scope of the present invention.
