thirdly, the internal fistula tumor size is convenient to measure, and because of long-term fixed-point puncture, the local vascular wall is thinned and is easy to bulge to form an aneurysm; premature use of an immature internal fistula can lead to excessive distension of the not yet thickened vessel wall to form an aneurysm; the oversized anastomotic stoma causes high blood flow velocity and high pressure to cause local bulging of internal fistula veins; the hematoma is repeatedly formed due to poor puncture technology; poor blood pressure control, excessive vein adventitia stripping, insufficient suturing during anastomosis and other reasons are all easy to cause aneurysm at the puncture site; the size of the internal fistula tumor is measured and observed through the syringe 3 with scales, so that a main doctor can conveniently guide a nurse to select a proper puncture part, and the tumor is prevented from being stimulated and damaged; meanwhile, medical staff can conveniently guide a patient to protect the tumor body from trauma, compression injury and infection; when a nurse dynamically observes an internal fistula tumor body, if an abnormality exists, a doctor can be timely reported, the vascular condition can be timely evaluated by ultrasound, and if an obvious vascular stenosis condition exists, the internal fistula tumor body can be treated as early as possible; meanwhile, if nurses find that the tumor body is too large in time, doctors can be informed of early surgical treatment, the risks of bleeding, blood loss, infection and pain discomfort of patients are reduced, and the life quality of the patients is improved; the appearance of the patient can be influenced by the oversized aneurysm, so that the uncomfortable appearance of the patient can be reduced by early treatment, and positive influence is provided for the treatment mood of the patient;
fourth, compare in traditional tape measure, ruler measurement mode, syringe 3 can accomplish to disinfect completely, guarantees that the internal fistula map is drawn, and the puncture point is measured and the whole aseptic technique of observation in-process reduces the patient and is infected the risk of puncture mouth by bacterium because of these operations.
The fixing mechanism comprises a needle handle sleeve 4 and a pasting part, wherein the pasting part comprises a lower layer of adhesive 5, an isolating layer 6 and an upper layer of adhesive 7 which are sequentially connected; the needle handle sleeve 4 is detachably arranged on the needle handle 2 in a penetrating mode, the lower-layer adhesive 5 and the upper-layer adhesive 7 are composed of an adhesive surface 8 with adhesion and a tearable adhesive film 9, and the adhesive surfaces 8 of the lower-layer adhesive 5 and the upper-layer adhesive 7 face towards the same direction.
The traditional internal fistula puncture needle head is fixed in the same way as the transfusion needle head is fixed when a patient is transfused, and three or more rubberized fabrics are adopted to fix the needle handle 2 on the arm of the patient in a sticking way; the fixation mode can gradually weaken the viscosity of the adhesive tape along with the time and the movement of the arm of the patient, and finally the adhesive tape falls off, and the needle handle 2 can not be fixed, so that the needle head body 1 is easy to fall off from the hand of the patient; if too many rubberized fabrics are adopted for fixation or the pressing force is large when the rubberized fabrics are adopted for fixation, the adsorption force of the rubberized fabrics on the arm of a patient is too strong, and the unsmooth blood circulation in blood vessels on the arm of the patient is easily caused, so that the tumor body of the venous tumor or the aneurysm is easily generated.
As shown in fig. 2, when the lower layer of adhesive 5 and the upper layer of adhesive 7 are in a spread state, tearing the tearable adhesive film 9 on the lower layer of adhesive 5 and the upper layer of adhesive 7, and adhering the adhesive surface 8 on the arm of a patient to complete the fixation of the device on the arm of the patient; compare in traditional adhesive tape is fixed, because the isolation layer 6 of this device does not have the viscidity, can not produce the adsorption affinity to patient's arm, will flow out the buffer area of blood circulation on the patient's arm, avoid appearing on the patient's arm because the tumor body that blood circulation is unsmooth and produce, simultaneously because have the cavity buffer area of isolation layer 6 as the adsorption affinity between lower floor's viscose 5 and the upper viscose 7, the activity of patient's arm can not directly collapse out lower floor's viscose 5 and upper viscose 7's viscose face 8 to ensure that fixed establishment can attach firmly on patient's arm and can not drop.
As shown in fig. 3, the fixing mechanism further comprises a fixing clip 10 for folding the lower adhesive 5 and the upper adhesive 7 together; the number of the sticking parts is two, and the sticking parts are symmetrically arranged at two sides of the needle handle sleeve 4.
