Description

Technical Field

[0001] The utility model belongs to the technical field of measuring tools, and in particular relates to a measuring device which is convenient to operate. Background Art

[0002] Nowadays, peripherally inserted central catheters (PICCs) are widely used in clinical practice, providing an ideal channel for cancer patients to infuse chemotherapy drugs and parenteral nutrition solutions. Basic arm circumference needs to be measured when PICC is placed, and when the PICC catheter is maintained, the patient needs to measure the arm circumference 10 cm above the elbow crease during self-monitoring at home and compare it with the arm circumference results recorded in the maintenance manual. If the arm circumference increases by more than 2 cm, there may be a risk of early thrombosis.

[0003] The position for measuring arm circumference is 10 cm above the elbow crease. However, the current arm circumference method is to first place the zero scale of the tape measure at the patient's elbow crease or the 10 cm scale of the tape measure at the elbow crease. When the arm circumference measurement position at 10 cm is determined, the tape measure needs to be used to wrap around the arm for a week to measure the patient's arm circumference. This measurement method makes the arm circumference measurement process cumbersome, and when the ruler leaves the position 10 cm above the elbow crease, it is easy to shift and cause position errors when the ruler is used to wrap around the arm. At the same time, the tape measure is easy to become loose during measurement (that is, it is difficult for the tape measure to fit tightly against the skin), and it is also easy to cause errors, resulting in poor accuracy of the measurement results. For this reason, we propose a measuring device that is easy to operate. Utility Model Content

[0004] The purpose of the utility model is to provide a measuring instrument that is easy to operate to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a measuring instrument that is easy to operate, comprising an arc-shaped plate, the bottom of which is fixedly connected to a vertical plate, the front of which is fixedly connected to a storage box, the interior of the storage box is movably sleeved with a rotating shaft, the exterior of the rotating shaft is fixedly sleeved with two baffles, and a tape measure is wrapped around the exterior of the rotating shaft, and a guide assembly is provided on the exterior of the tape measure.

[0006] As a preferred embodiment, the front side of the arc-shaped plate is provided with scale lines, and the inner side of the arc-shaped plate is fixedly connected with a protective pad.

[0007] As a preferred embodiment, the front side of the vertical plate is provided with scale lines, and the vertical plate is located in the middle of the bottom end of the arc-shaped plate.

[0008] As a preferred embodiment, the external movable sleeve of the top end of the rotating shaft is provided with a mounting block, the mounting block is fixedly connected to the top of the inner cavity of the storage box, and the bottom end of the rotating shaft is fixedly connected with a rotating knob.

[0009] As a preferred embodiment, the tape measure is located between the two baffles, and one end of the tape measure passes through and extends to the outside of the storage box, and a rubber ring is provided between the tape measure and the baffles.

[0010] As a preferred embodiment, the guide assembly includes a clamping plate, the outer side of the clamping plate is fixedly connected to the inner side of the storage box via a connecting plate, and the inner side of the clamping plate is fixedly connected to a limiting pad.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The easy-to-operate measuring device is provided with an arc plate, a vertical plate, a storage box and a tape measure. During the process of measuring the arm circumference of a patient, the arc plate can be directly clamped at a position ten centimeters above the transverse line of the patient's elbow, and the tape measure can be pulled to measure the arm circumference at that position. This makes the process of measuring the arm circumference simpler and more convenient, and the measuring position will not shift, thereby effectively preventing the occurrence of position errors.

[0013] The easy-to-operate measuring device is provided with a rotating shaft, a mounting block and a rotating knob. During the process of measuring the arm circumference of a patient, the measuring tape can be retracted after being wound around once, so that the measuring tape can be closely attached to the patient's arm skin, thereby preventing the measuring tape from becoming loose and reducing the measurement error, thereby making the arm circumference measurement result more accurate.

[0022] In this embodiment, the material of the arc plate 1 is elastic material, and the length of the vertical plate 2 is ten centimeters. When the PICC catheter needs to measure the patient's arm circumference, the patient can first place the bottom end of the vertical plate 2 on the elbow crease of the arm, and stick the vertical plate 2 to the arm. At this time, the arc plate 1 will be stuck at the patient's arm circumference, and the position of the arc plate 1 is the position to be measured, avoiding the traditional need to first use the tape measure 8 to measure the ten-centimeter position of the arm from the elbow crease of the arm, and then use the tape measure 8 to measure the arm circumference from the ten-centimeter position of the arm, which is cumbersome. The problem makes it easier and more convenient to measure the patient's arm circumference.

[0024] In this embodiment, after the arc plate 1 is stuck on the patient's arm, the tape measure 8 is pulled to stretch and move the tape measure 8, causing the tape measure 8 to wrap around the patient's arm until the end of the tape measure 8 contacts the other side of the storage box 3, and then the rotating knob 6 is turned to rotate the shaft 4, and the shaft 4 will cause the tape measure 8 to retract, so that the tape measure 8 can fit closely to the patient's arm skin, preventing the tape measure 8 from loosening, reducing the measurement error, and making the arm circumference measurement result more accurate.

[0025] See also Figure 2 and Figure 4The outer part of the tape measure 8 is provided with a guide assembly 10, and the guide assembly 10 includes a clamping plate 101, the outer part of the clamping plate 101 is fixedly connected to the inner side of the storage box 3 through a connecting plate 102, and the inner side of the clamping plate 101 is fixedly connected to a limiting pad 103;

[0026] In this embodiment, when the tape measure 8 moves in a telescopic manner, the limit pad 103 will position the movement direction of the tape measure 8, avoiding the problem of the tape measure 8 being offset during movement, so that the tape measure 8 can be more accurately wrapped around the outside of the rotating shaft 4 when retracting, thereby bringing convenience to the use of the tape measure 8.

[0027] The working principle and use process of the utility model are as follows: first, when the PICC catheter needs to measure the patient's arm circumference, the patient can first place the bottom end of the vertical board 2 at the elbow crease of the arm, and stick the vertical board 2 to the arm, at this time, the arc board 1 will be stuck at the patient's arm circumference, and the position of the arc board 1 is the position that needs to be measured;

[0028] Then, the tape measure 8 is pulled to stretch and move the tape measure 8, so that the tape measure 8 is wrapped around the patient's arm until the end of the tape measure 8 contacts the other side of the storage box 3, and then the rotating knob 6 is turned to rotate the shaft 4, and the shaft 4 will cause the tape measure 8 to retract, so that the tape measure 8 can fit closely to the patient's arm skin, preventing the tape measure 8 from loosening, reducing the measurement error, and making the arm circumference measurement result more accurate;

[0029] Finally, when the tape measure 8 is telescopically moved, the limit pad 103 will position the movement direction of the tape measure 8, avoiding the problem of the tape measure 8 being offset during movement, so that the tape measure 8 can be more accurately wrapped around the outside of the rotating shaft 4 when retracting, thereby bringing convenience to the use of the tape measure 8.
