Description

Technical Field

[0001] The invention belongs to the technical field of measuring belts, in particular to an abdominal circumference measuring belt for critically ill patients. Background Art

[0002] Abdominal circumference refers to the circumference of the abdomen. When caring for critically ill patients who are bedridden for a long time, in order to regularly track the physical data of critically ill patients, it is necessary to use various measuring tools to measure the patient's physical data. Among them, when measuring the patient's abdominal circumference, a flexible tape measure is usually used to pass through the patient's iliac crest and then measure the abdominal circumference. Since some critically ill patients are bedridden, the patient's body needs to be lifted up when the tape measure passes directly under the patient's body, so that the patient needs to make large limb movements, which can easily cause damage to the patient's body. If the tape measure is directly passed under the patient's head or legs and then moved to the position to be measured, the patient will press the tape measure due to the weight of the patient's body, making it difficult for the tape measure to move to the position to be measured, making the patient's abdominal circumference measurement troublesome.

The guide structure 4 includes a steel wire 41, a fixing seat 42 arranged at the head end of the steel wire 41, and a dial ring 43 arranged at the end of the steel wire 41. A hook 14 is also provided on the rear end surface of the storage shell 1, and the head and tail ends of the steel wire 41 are rotatably connected to the fixing seat 42 and the dial ring 43 respectively.

[0032] In the present invention, a storage cavity 11 is provided at the top of the storage shell 1, and a through opening 12 is provided on the rear end surface of the storage shell 1. The through opening 12 is connected to the storage cavity 11. The winding disk 2 is arranged in the storage cavity 11, and the measuring tape 3 can pass through the through opening 12. When the winding disk 2 is rotated in the storage cavity 11, the measuring tape 3 and the guide structure 4 can be wound onto the winding disk 2 in sequence, thereby achieving the purpose of storing the measuring tape 3 and the guide structure 4.

[0033] The end of the storage shell 1 away from the storage cavity 11 is also integrally formed with a circular handle ring 15, which is convenient for carrying the waist circumference measuring belt.

[0034] Specifically, a top cover 13 is installed at the cavity mouth of the storage cavity 11, a convex column 131 is provided on the bottom surface of the top cover 13, a sleeve hole 132 is provided on the bottom end surface of the convex column 131, a concave cavity 21 is provided at the top end of the winding disk 2, and a convex shaft 211 is provided at the bottom of the concave cavity 21. When the winding disk 2 is placed in the storage cavity 11, the convex shaft 211 extends into the sleeve hole 132 and is rotatably connected to the convex column 131, so that the winding disk 2 can rotate around the convex column 131 under the action of the convex shaft 211.

[0035] Furthermore, a coil spring 22 is provided in the concave cavity 21, the head end of the coil spring 22 is embedded in the side wall of the concave cavity 21, and the tail end of the coil spring 22 is embedded in the outer surface of the protruding column 131. The coil spring 22 is in a pre-tightened state in the concave cavity 21, so that under the elastic force of the coil spring 22, the measuring tape 3 and the guide structure 4 are always wound on the winding disk 2.

[0036] In addition, a winding groove 23 is provided on the outer surface of the winding disk 2. The head end of the measuring tape 3 is fixed at the bottom of the winding groove 23. The measuring tape 3 is wound in the winding groove 23. When the winding disk 2 rotates, the measuring tape 3 and the guide structure 4 can be wound into the winding groove 23, thereby achieving the purpose of storing the measuring tape 3 and the guide structure 4.

[0037] In the above scheme, a pair of clamping plates 421 are provided at the head end of the fixing seat 42, and the two clamping plates 421 are clamped on the end of the measuring tape 3. A pin 422 is inserted between the two clamping plates 421, and the pin 422 passes through the end of the measuring tape 3, so that the end of the measuring tape 3 is fixed on the fixing seat 42, thereby achieving the purpose of connecting the measuring tape 3 and the guide structure 4.

[0038] Specifically, both ends of the steel wire 41 are sleeved and fixed with end sleeves 411, the end of the end sleeve 411 is provided with a convex ball 412, the head end of the fixed seat 42 is provided with a first clamping seat 423, and the side end of the first clamping seat 423 is installed with a second clamping seat 424 by bolts, and a clamping cavity 425 is provided on the inner surface of the first clamping seat 423 and the second clamping seat 424, and the convex ball 412 is sleeved in the clamping cavity 425, so that the head end of the steel wire 41 is restricted between the first clamping seat 423 and the second clamping seat 424 by the convex ball 412, and can rotate between the first clamping seat 423 and the second clamping seat 424.

[0039] Furthermore, a fixing ring 413 is fixed on the end sleeve 411 near the dial ring 43, and a hanging plate 431 is provided at the head end of the dial ring 43. The end sleeve 411 passes through the hanging plate 431 and is rotatably connected to the hanging plate 431. The end sleeve 411 is hung on the hanging plate 431 through the convex ball 412, so that the tail end of the steel wire 41 is rotatably connected to the dial ring 43. Among them, a through hole 432 is provided in the middle of the hanging plate 431, and the aperture of the through hole 432 is greater than or equal to the outer diameter of the steel wire 41 and smaller than the ball diameter of the convex ball 412. The hanging plate 431 is located between the convex ball 412 and the fixing ring 413, which can prevent the end sleeve 411 from falling off the dial ring 43. After the steel wire 41 passes under the patient's head and neck or under the legs, the two ends of the steel wire 41 are pulled, so that the steel wire 41 can be moved horizontally under the patient's body and rotated between the fixing seat 42 and the dial ring 43, thereby reducing the friction between the steel wire 41 itself and the patient's body, so that the steel wire 41 can be more easily While being pressed by the patient's body, the measuring tape 3 is moved laterally under the patient's body. When the steel wire 41 is moved to the position required for measurement, the dial ring 43 is pulled outward to enable the guide structure 4 to drive the measuring tape 3 to pass directly under the patient's body. At this time, by hanging the dial ring 43 on the hook 14 and loosening the storage shell 1, the winding disk 2 can reel up the measuring tape 3 under the elastic force of the coil spring 22, so that the tail end of the storage shell 1 fits the patient's body. At this time, the reading on the measuring tape 3 corresponding to the position of the through hole 12 is the abdominal circumference value required to be measured. It is easy to use and does not require the patient to make large body movements.

[0040] The working principle of the abdominal circumference measuring belt for critically ill patients of the present invention is specifically as follows:

[0041] After the wire 41 has been moved to the desired measurement position, the dial ring 43 is pulled outward along the direction of the guide structure 4 so that the guide structure 4 can drive the measuring tape 3 to pass directly under the patient's body. At this time, after the dial ring 43 is hung on the hook 14 and the storage shell 1 is released, the winding disk 2 can rewind the measuring tape 3 under the elastic force of the winding spring 22, so that the tail end of the storage shell 1 fits the patient's body, so that the nurse can achieve the purpose of abdominal circumference measurement by observing the reading on the measuring tape 3 corresponding to the position of the through hole 12. It is easy to use and does not require the patient to make large body movements.
