Detailed Description
The utility model is further illustrated by the following examples, which are intended to be illustrative only and not limiting in any way.
An infusion port lancing auxiliary assembly as shown in fig. 1 includes: the fixing seat 1 and the protective cap 2.
As shown in fig. 2, the fixing base 1 includes a bottom plate 101 and a boss 102, a through hole 103 is formed in the center of the bottom plate 101, the through hole 103 is sized to be just sleeved on an infusion port in the body, the boss 102 is located on the top surface of the bottom plate 101, and the boss 102 is annular and surrounds the through hole 103. By utilizing the bottom plate 101 structure of the fixing seat 1, the contact area is increased, and the medical staff can take and use conveniently. In addition, the extension of the bottom plate 101 of the fixing seat 1 can be enhanced by pressing the index finger and the thumb separately. The through hole 103 in the center of the bottom plate 101 and the boss 102 surrounding the through hole 103 are sleeved outside the body to fix the infusion port, prevent the subcutaneous migration, improve the puncture success rate and reduce the pain of patients.
The outline of the edge of the bottom plate 101 is hexagonal, two opposite straight edges of the bottom plate 101 are convenient for the index finger and the thumb to press and fix separately, the contact between the other straight edges and the hand is reduced as much as possible, the pressing force of the finger is concentrated to the two opposite straight edges of the bottom plate 101 to the greatest extent, meanwhile, the damage to the other straight edges by the hand is avoided, and the material is saved.
As shown in fig. 3, the protective cap 2 is a cylinder, the bottom is open, and two openings 201 are formed in the bottom side wall of the protective cap 2. The structure of the protective cap 2 is utilized to prevent the puncture needle from rebounding, so that medical staff is stabbed, through the arrangement of the two openings 201, the cotton swab presses the puncture point through the other opening 201 of the protective cap 2, and the other index finger and the thumb pinch the two wings of the puncture needle to pull out the needle. Therefore, the puncture point can be effectively pressed during the needle pulling operation, bleeding can be reduced, and the recovery of a patient is facilitated.
The boss 102 has a top surface with an annular clamping groove 105. The bottom of the protective cap 2 can be inserted into the annular clamping groove 105. The annular clamping groove 105 of the boss 102 is convenient for clamping and fixing the protective cap 2, and is also beneficial to disassembling the protective cap 2.
