Description

Arteriovenous fistula marker puncture and its fixation device

technical field

The invention relates to the field of medical technology, in particular to an arteriovenous fistula marking puncture and a fixing device thereof.

Background technique

In clinical arteriovenous fistula puncture methods, there are three regional methods, rope ladder method, and buttonhole method. As the name implies, the local method is relatively fixed puncture area, which is easy to puncture. It requires low puncture level and high success rate in the early stage, but long-term puncture can easily lead to various puncture complications of internal fistula, reduce the service life of internal fistula and increase patient pain. . The rope ladder method is to puncture each puncture point (arterial point, venous point) equidistantly (0.5-1cm) in a step-by-step manner, and establish 3-5 puncture points for cyclic reciprocating puncture, which can reduce puncture complications and prolong the service life of the internal fistula. There are requirements on the length of the vessel, and the caregiver is required to memorize each point and its sequence of reciprocating cycles. Finally, for buttonhole puncture, he uses a fixed-point, fixed-depth, and fixed-angle puncture to form a tunnel within a certain period of time, and then strictly aseptically removes the scab and blunt needle puncture with the highest success rate and low complications. For the three puncture methods, according to the (NKF-DOQI) international guidelines, in order to reduce the occurrence of access complications, the latter two puncture methods are advocated, but faced with the reality of undergraduates, the workload of nurses is heavy, the mobility is high, and young people account for 40% of undergraduates. And the level of puncture is uneven. Although the puncture is performed as required, the execution rate is low and the implementation cannot be fully carried out. In view of the above defects, it is necessary to design arteriovenous fistula marking puncture and its fixing device.

Further, its working steps are as follows:

⑴. Insert the patient's arm into the support plate along the guide plate first, and turn the inner side of the patient's arm upward, so that the inner side of the patient's arm is completely exposed to the outside world, that is, the patient's arteriovenous part is exposed to the outside world;

(2) When the patient's arm is placed in the support plate, the patient's arm exerts a squeezing force on the splint, so that the splint exerts a squeezing force on the spring in the placement groove;

(3) Under the action of spring resilience, the splint exerts anti-extrusion force on the patient's arm, so that the patient's arm is in a fixed position in the device;

⑷, the medical staff then take out the marker pen and scale from the storage box;

⑸. Then use an external B-ultrasound machine to irradiate the patient's arteriovenous parts exposed to the outside world, and observe and evaluate the shape of the arteriovenous vessels, the width of the lumen, the presence or absence of vascular branches, the accompanying arteries, and the length of available vessels;

⑹. Use the marker pen and scale to mark the puncture point on the inside of the patient's arm.

Further, the marker pen and the scale are disinfected before the step (5).

Further, before the step (5), the arteriovenous part of the patient is disinfected.

Further, the soft pad is to allow the splint to exert a soft extrusion force on the patient's arm and protect the patient.

Compared with the prior art, the arteriovenous fistula marker puncture and its fixing device have ingenious structure, powerful functions and simple operation. First, the patient's arm is fixed, so that the patient's arteriovenous part is exposed to the outside world and is fixed. , the medical staff then use the B-ultrasound machine to observe and evaluate the arteriovenous vessel shape, lumen width, whether there are vascular branches, accompanying arteries, and the length of the available blood vessels, and then use a marker pen and a scale to measure the patient's arm. The puncture point is marked on the inside, which can effectively reduce the complications of internal fistula puncture, reduce the pain of patients and improve the quality of dialysis.

Detailed ways

In the following, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known processing steps have not been described in detail.

Example

The arteriovenous fistula marking puncture and its fixing device include a support plate 1, a placement groove 2, a spring 3, a splint 4, a cushion 5, a guide plate 6, and a placement box 7. The number of placement grooves 2 is several pieces. The placement groove 2 is evenly distributed on the left and right sides of the upper end of the support plate 1, the placement groove 2 is integrally connected with the support plate 1, the spring 3 is located inside the placement groove 2, and one end of the spring 3 is connected to the placement groove. 2 are connected by glue, the splint 4 is located at the other end of the spring 3, one end of the splint 4 is connected with the spring 3 by glue, the cushion 5 is located at the other end of the splint 4, and the cushion 5 is connected with the splint 4 by glue , the guide plate 6 is located at the top of the splint 4, the guide plate 6 is integrally connected with the splint 4, the placement box 7 is located on the left side outside the support plate 1, and the placement box 7 is screwed to the support plate 1 .

Its working steps are as follows:

(1) First insert the patient's arm into the support plate 1 along the guide plate 6, and turn the inner side of the patient's arm upward, so that the inner side of the patient's arm is completely exposed to the outside world, that is, the patient's arteriovenous part is exposed to the outside world;
