Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device auxiliary device technology, specifically relating to a repositionable and anti-detachment label for stethoscopes, and more particularly to a stethoscope-specific labeling device that achieves non-destructive fixation and reusability through an elastic clamping structure and ergonomic design. Background Technology
[0002] In the existing technology, stethoscope labels have the following drawbacks:
[0003] 1. Existing labels use a single-sided snap-on design, which has a detachment rate of up to 40% when medical staff move quickly. To reduce the problem of single-sided snap-on detachment, glue is usually added to fix the snap-on structure.
[0004] 2. Another method of fixing labels in the existing technology is a spring clip structure. However, the spring clip structure can cause indentations with a depth of ≥0.2mm on the surface of the stethoscope tubing during long-term use, resulting in a deterioration in sound quality.
[0005] Therefore, how to provide a stethoscope label that is aesthetically pleasing, prevents detachment, and allows for non-destructive fixation of the stethoscope tubing while being reusable has become a pressing technical challenge for the industry. Summary of the Invention
[0006] One of the purposes of this utility model is to provide a stethoscope label that is aesthetically pleasing, prevents detachment, and allows for non-destructive fixation of the stethoscope tubing and is reusable.
[0007] One of the objectives of this invention is achieved as follows:
[0008] A stethoscope label includes an integrally formed elastic body. The elastic body includes a fixing part, a first clamping part, and a second clamping part connected to the fixing part. The first clamping part has a fan-shaped bottom base plate and four side walls extending from the periphery of the bottom base plate to the same side. The four side walls include a first side wall, a second side wall, a third side wall, and a fourth side wall. The four side walls are inclined inward to form a constricted clamping groove. The second clamping part is a fan-shaped body adapted to the shape of the bottom base plate and is completely embedded in the clamping groove. The first clamping part and the second clamping part form an elastic opening and closing structure through the fixing part. The top ends of the four side walls are provided with limiting pressure edges extending into the clamping groove. The limiting pressure edges are formed by bending and extending from the top ends of the four side walls into the clamping groove. The limiting pressure edges are a continuous structure.
[0009] In the above scheme, the limiting pressure edge can be a continuous ring structure.
[0010] In the above scheme, the slopes of the first sidewall, the second sidewall, the third sidewall, and the fourth sidewall are all greater than 5° and less than 10°.
[0011] In the above scheme, the distance between the inner edge of the limiting pressing edge and the outer surface of the second clamping part is 0.5-1.2mm.
[0012] In the above scheme, the central angle of the fan ring of the bottom substrate D is greater than 115° and less than 125°.
[0013] In the above scheme, the elastic body has a Shore hardness of 45A ≤ Shore A ≤ 65A.
[0014] In the above solution, the limiting pressure edge is provided with a notch above the connection between the fixing part and the first clamping part, and the width of the notch is adapted to the width of the fixing part.
[0015] 1. This utility model achieves a lateral displacement resistance of 14.2N through a four-way limiting structure, effectively preventing detachment. Existing technology has a vibration test detachment rate of 18.7%, while this utility model reduces the vibration test detachment rate to less than 1%.
[0016] 2. When the label for the stethoscope of this utility model is fixed in conjunction with the tubing, the contact pressure on the tubing is 0.06-0.08 MPa, which is significantly lower than the tubing damage threshold (0.15 MPa). Attached Figure Description
