Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a fistula puncture calibration pad. Background Art

[0002] The most commonly used vascular access for hemodialysis patients is the arteriovenous fistula, which is often referred to as the patient's "lifeline". The most commonly used regional puncture method often causes fistula-related complications such as vascular bleeding, stenosis, and thrombosis. Through consulting a large amount of literature and expert consensus recommendations, rope ladder puncture is the preferred puncture method, and it can greatly reduce patients' fistula-related complications.

[0003] However, it still has the following disadvantages in actual use:

[0004] Existing fistula punctures have no positioning and quantitative tools and rely on experience. The specific positioning is unclear, and the puncture position cannot be accurately and orderly located. The fistula vascular direction map is not convenient for positioning and use on a computer or paper, or it is temporarily drawn on the arm, which cannot present a continuous and orderly puncture record.

[0005] Therefore, a new fistula puncture calibration pad is proposed to solve the above problems. Utility Model Content

[0006] Technical issues to be solved

[0007] The purpose of the utility model is to provide a calibration pad for fistula puncture, so as to solve the problems in the above-mentioned background technology that the existing fistula puncture has no positioning and quantification tools, relies on experience for operation, the specific positioning is unclear, the puncture position cannot be accurately and orderly positioned, the fistula vascular direction diagram is not convenient to locate and use on a computer or paper, or is temporarily drawn on the arm, and cannot present a continuous and orderly puncture record.

[0008] Technical Solution

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] The utility model is a fistula puncture calibration pad, comprising:

[0011] The calibration pad body, the patient file record information located in the upper left corner of the calibration pad body, the scale lines on the outer surface of the calibration pad body, the fixed point located in the center of the outer surface of the calibration pad body and the indicator arrow located in the upper center of the calibration pad body.

[0012] Furthermore, the calibration pad body is made of soft and transparent PVC material;

[0013] Specifically, the fistula puncture calibration pad is made of soft and transparent PVC material, which fits tightly to the patient's skin, has accurate positioning, and is easy to clean and disinfect.

[0014] Furthermore, the patient file record information is three pieces of information, one for the dialysis number, one for the patient's name, and one for the fistula location;

[0015] Specifically, there is an exclusive area on the pad to register the basic information of the patient's fistula with the calibrated blood vessels, which is convenient for viewing and archiving.

[0016] Furthermore, the scale scale lines are horizontal and vertical scale scale lines, and the horizontal and vertical scale scale intervals are centimeters;

[0017] Specifically, a ruler scale is set up with 1cm as the basic unit scale and 1cm long * 1cm wide as the grid format, which is clear and has accurate spacing, which can not only maintain the usable length of the fistula blood vessel, but also make the interval distance meet the optimal two-point puncture distance for the recovery of the fistula blood vessel. The ruler scale lines are not easy to wear and do not cover the blood vessel puncture point.

[0018] Furthermore, the fixing point corresponds to the middle position of the antecubital fossa;

[0019] Specifically, the fistula puncture calibration pad is 35 cm long and 15 cm wide, with the center of the elbow as the 0 scale, and a 1 cm size is provided for positioning the blood vessels in the patient's arm.

[0020] Furthermore, the indicating arrow is the direction of the fistula;

[0021] Specifically, the arrow indicates the direction of the fistula, which facilitates the determination of the direction of the calibration pad body.

[0022] Beneficial Effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] The utility model can accurately locate the vascular puncture points, and the interval between each puncture point is planned to ensure that the blood vessels have enough time to heal. The puncture point map is planned on the fistula calibration pad, which is convenient for different operators to perform unified and orderly puncture. The fistula puncture calibration pad marks the patient's fistula information for easy archiving and checking the patient's vascular access puncture planning at any time.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
