When the conventional human arteriovenous puncture is carried out, the skin is required to be punctured by an injection needle, severe pain can be generated, and in order to relieve or even eliminate the pain, the surface of the skin can be smeared with a gunny before the puncture, and the puncture is carried out after 1 to 1.5 hours of anesthesia, so that the patient hardly feels the pain, and the technology is called pre-anesthesia of the skin before the puncture.
However, at present, there are three difficulties in performing the skin pre-anesthesia technique, namely, the need to apply the drug to the exact location, generally requiring a specialized medical staff to confirm; secondly, the medicine needs to be fixed on the puncture part for a long time without affecting the movement of the patient; finally, for children or children who need multi-site pre-anesthesia, the dosage of the medicine is well mastered to prevent the excessive anesthetic.
The Chinese patent with the bulletin number of CN 208625813U discloses a novel epidural anesthesia puncture positioning device, when the device adopting the scheme is used for anesthesia, a first binding belt and a second binding belt are fixed on the back through a fastening belt and a fastening rope, a sliding fixed sleeve is fixed by a limiting device, a rotary table is fixed by a limiting pin after being rotated to a proper angle, the position of a fixed limiting ring on a puncture needle body is adjusted according to the requirement of puncture depth, a hand-held puncture needle punctures downwards, and continuous puncture can be prevented when the fixed limiting ring contacts the fixed sleeve, namely, the preset puncture depth is reached. The scheme only determines the puncture position, does not involve skin anesthesia before puncture, cannot perform pre-anesthesia, and cannot effectively determine an anesthetic region.

According to the use method, when the skin pre-anesthesia device is used for pre-anesthesia, only medical staff is needed for positioning and marking, the patient or guardian can perform pre-anesthesia by himself, meanwhile, the accuracy and the effectiveness of an anesthesia area can be ensured, the use convenience is improved, and the problems that the medicine applying time is long and the patient has to wait for a long time are solved.
When the positioning device 1 is used for positioning and marking, the puncture positioning point 12 is placed at the puncture point position, the direction of the positioning device 1 is adjusted, the expected vascular running direction is coincident with the symmetry axis of the positioning device 1 (auxiliary positioning can be carried out through an arrow 17), and the trace of the anesthesia positioning ring 11 and the puncture positioning point 12 is pressed and left.
The invention carries out clinical test, and the clinical test process and the result are as follows:
the skin pre-anesthesia device is suitable for identifying blood vessels before intravenous infusion puncture and fixing surface anesthesia medicines.
The following method is specifically followed when in use:
the package is torn open and the fixture 2 is removed.
Before venipuncture, medical staff identify the pre-puncture part, and use the positioning device 1 to position and mark, and inform a patient or guardian to fix the fixing device 2 according to the mark about 1.5 hours before puncture.
About 1.5 hours before puncturing, the release paper 22 is peeled off, and the medicine region 211 of the fixing device 2 is aligned with the pre-marked part and stuck on the skin.
The fixture 2 is smoothed.
Prior to puncturing, the fixation device 2 is removed by the healthcare staff: gently pinching the edge of the fixing device 2, tearing off slowly according to the hair growth direction, cleaning and disinfecting the skin at the puncture part, and completing the puncture.
Notice that:
before use, the intravenous infusion site, the blood drawing site or the pre-marked site for skin pre-anesthesia is cleaned and should be ensured to be completely dry.
The skin was kept dry and free of surface tingling paste residues prior to puncturing.
When the fixing device 2 is used, unnecessary pulling during pasting and tearing should be avoided, so that inaccuracy of the dosage of the medicine area 211 and mechanical damage of the skin are avoided.
The skin pre-anesthesia device is independently packaged, and if the skin pre-anesthesia device is broken or opened, a brand new and intact product should be replaced.
Products with different specifications are selected according to different patients so as to ensure that the products are attached to the skin and the dosage is not excessive, and the best use effect is obtained.
The skin pre-anesthetic device should be frequently observed for signs of abnormality in the site of attachment, and should be immediately stopped and the medical staff be called for as soon as abnormality occurs (common symptoms include pain, redness, swelling, itching, etc.).
The skin pre-anesthesia device should be stored below 15-30 deg.C at room temperature, and has a service life of 3 years.
Clinical test results:
to verify the effectiveness of the device according to the relevant principles, a skin pre-anesthetic device was clinically prepared according to the protocol described in the present invention, and the effectiveness, comfort and side effects of the device were evaluated, with 15 clinical patient effect evaluations.
The age and sex statistics of 15 clinical patients are shown in Table 1.
A total of 15 patients participated in the trial, 10 men, 5 women, and an average age of 15.6 years.
Table 1: participated patient age gender statistics
Effectiveness, comfort and side effects are shown in Table 2.
Device validity evaluation: the 15 cases of gunpowder positions are not moved, so the effectiveness of the device is ideal, and normal dressing activities are not affected. Of which 14 (93.3%) did not affect motion at all.
Comfort and side effect evaluation: the skin has no edema, 1 (6.7%) has burning sensation, 2 (13.3%) has itching sensation, and part of the skin appears reddish or whitish, and the overall comfort is good without obvious side effect.
Evaluation of device applicability: because the device is temporarily combined, the applicability is poor, 5 cases of falling off of different reasons and different degrees occur, but the fixing of the gunpowder is not changed, namely the position of the medicine area 211 is not moved.
