Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an arm circumference measuring device for patients with PICC tubes. Background Art

[0002] In order to ensure the safety and effectiveness of PICC catheterization, patients need to promptly detect and deal with possible complications. Currently, the upper limb arm circumference is usually measured and recorded to dynamically detect whether PICC catheterization patients have complications such as infection and thrombosis. Existing traditional measuring tools generally use rulers or tape measures to measure and record the patient's upper arm circumference at intervals. However, since the arm circumference at a position 10 cm above the transverse line of the elbow fossa is generally used as the measurement standard for measuring the upper arm circumference, medical staff or patients need to manually locate the measurement position of the upper arm circumference during the measurement process. The measurement operation steps are complicated, the measurement time is long, and there are problems such as inaccurate position determination and influence of subjective factors, which lead to inaccurate measurement results and reduced compliance and consistency of patients in measuring arm circumference. In addition, when the existing tape measure is wrapped around the upper limb to measure the arm circumference, the tape measure is very likely to deviate, that is, the tape measure does not form a perfect circle perpendicular to the upper limb during the measurement process, but forms an ellipse with an offset angle to the upper limb, which leads to a larger measurement result. Especially after multiple interval measurements and records, the biased measurement results are very likely to mislead medical staff and patients, resulting in the failure to timely discover the existence of complications and affecting the normal treatment of patients.

[0003] Therefore, it is necessary to design an arm circumference measuring device for PICC patients with tubes that is easy to use and has high measurement accuracy. Summary of the invention

[0004] In order to solve the above technical problems, the utility model proposes an arm circumference measuring device for patients with PICC tubes. The device has a simple structure and is easy to use. It can reduce the difficulty and complexity of arm circumference measurement. It does not need to manually press and fix the transverse lines of the cubital fossa, which is convenient for patients to measure the upper limb arm circumference by themselves. It can also effectively avoid the deviation of the measuring ruler during the circling process, thereby improving the accuracy of the measurement.

[0021] (3) The measuring ruler is detachably connected to the positioning plate through a snap-in hole and a bolt, which makes it easy to replace the measuring ruler, thereby reducing the cost of use and maintenance.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.

[0030] Embodiment 1:

[0031] like Figure 1 to Figure 6 As shown, the utility model provides an arm circumference measuring device for a patient with a PICC tube, which comprises a positioning plate 1, a measuring ruler 2 and a clamping arm 3.

[0032] Combination Figure 1 , Figure 4As shown, a slot 11 is provided at the upper end of the positioning plate 1, and the slot 11 is adapted to the measuring ruler 2. A reading marking line 12 is provided at the lower edge of the positioning plate 1 near the slot 11, and the distance between the lower end edge of the positioning plate 1 and the lower edge of the slot 11 is 10 cm.

[0033] like Figure 5 As shown, the bottom end surface of the positioning plate 1 is provided with an inner concave arc surface 15 to fit the surface of the upper limb arm. Figure 4 , Figure 5 As shown, the upper end of the positioning plate 1 is provided with a clamping hole 13 penetrating the clamping slot 11, and a bolt 14 which can be embedded in the clamping hole 13. There are two clamping holes 13 and two bolts 14. Figure 2 , Figure 3 As shown, the measuring ruler 2 is provided with a docking hole 24 arranged opposite to the snap-in hole 13, and the docking hole 24 passes through the measuring ruler 2, so that the bolt 14 passes through the docking hole 24 and is inserted into the snap-in hole 13 at the lower edge of the slot 11, thereby realizing a fixed connection between the measuring ruler 2 and the positioning plate 1.

[0034] Optionally, in some embodiments, the engaging hole 13 is provided with an internal thread, and the bolt 14 is provided with an external thread.

[0035] like Figure 4 , Figure 5 As shown, the clamp arm 3 is arranged near the lower end of the positioning plate 1, and it does not overlap with the edge line of the lower end of the positioning plate 1, so that when the lower end of the positioning plate 1 abuts against the transverse line of the elbow fossa, the clamp arm 3 is clamped above the elbow joint. Specifically, the clamp arm 3 includes a symmetrically arranged and bendable arc-shaped left clamp arm 31 and a right clamp arm 32. The clamping degree of the clamp arm 3 on the upper limb can be adjusted by bending the left clamp arm 31 and the right clamp arm 32. At the same time, it can be suitable for patients of different physiques to ensure that the measuring device can be stably clamped at the upper limb position without manual pressing.

[0036] Combination Figure 2 , Figure 4 as well as Figure 6 As shown, the measuring ruler 2 can be bent so as to wrap around to measure the arm circumference. The measuring ruler 2 is embedded in the card slot 11, which is arranged vertically with the positioning plate 1. A measuring scale line 23 is provided on the lower edge of the measuring ruler 2, and the initial scale line (0 scale line) of the measuring scale line 23 is aligned with the reading identification line 12 of the positioning plate 1, so that after wrapping around once, the scale at which the measuring scale line 23 of the upper measuring ruler 2 is opposite to the reading identification line 12 is the measurement value of the upper limb arm circumference.

[0037] like Figure 3As shown, the top of the measuring ruler 2 is provided with a positioning convex strip 21 parallel to it, and the bottom is provided with a positioning groove 22 parallel to it. The positioning convex strip 21 is adapted to the positioning groove 22 and the two are arranged opposite to each other to ensure that the measuring ruler 2 does not deviate during the process of wrapping around the upper limb. In the specific use process, combined with Figure 6 As shown, after wrapping around the upper limb, ensure that the positioning groove 22 at the end of the measuring ruler 2 is pressed on the positioning convex strip 21 at the initial end (0 scale line end) of the measuring ruler 2. If the positioning convex strip 21 cannot be completely embedded in the upper positioning groove 22, it proves that the measuring ruler 2 is offset during the wrapping process, and the measuring ruler 2 at other positions needs to be adjusted until the positioning convex strip 21 is completely embedded in the positioning groove 22.

[0038] like Figure 4 As shown, a clamping strip 111 adapted to the positioning groove 22 is provided at the bottom of the clamping slot 11 to improve the stability and accuracy of the measuring ruler 2 embedded in the clamping slot 11 and ensure that the measuring ruler 2 is perpendicular to the positioning plate 1 .

[0039] Optionally, in some embodiments, the measuring ruler 2 is a bendable soft ruler.

[0040] In summary, the arm circumference measuring device for patients with PICC tubes provided by the utility model has a simple structure and is easy to use, which can reduce the difficulty and complexity of arm circumference measurement. There is no need to manually press and fix the transverse lines of the cubital fossa, which is convenient for patients to measure the upper limb arm circumference by themselves, and can effectively avoid the deviation of the measuring ruler during the circling process, thereby improving the measurement accuracy.

[0041] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
