Abstract
The utility model provides a semiautomatic vein puncture apparatus, which belongs to the medical apparatus. The semiautomatic vein puncturing apparatus mainly comprises a base seat, a fixed support, a rotating support and a vein puncturing needle. The base seat is of board structure and a bar-shaped hole is arranged in the middle of the board, the fixed support is fixed and connected with the base seat, the upper part of the fixed support is spliced with the rotating support, one end of the rotating support is spliced with the fixed support through a jointed shaft, the bottom surface of the other end is connected with the vein puncturing needle, and a connecting line from the needlepoint of the puncturing needle to the jointed shaft is perpendicular to the needle body. The utility model can help the medical care personnel to control the puncturing angle and the puncturing depth, and the utility model has the characteristic of high success rate and quick speed.
Description
(1) technical field:
This utility model belongs to medical apparatus and instruments, mainly proposes a kind of semi-automatic venipuncture device.
(2) background technology:
Venipuncture is a hospital clinical means of administration commonly used.And the venipuncture administration still relies on artificial straightforward manipulation at present clinically, be that the needle angle and the degree of depth etc. rely on medical personnel's experience to grasp fully, this is for some medical personnel (especially not long medical personnel of clinical position time), the needle angle and the degree of depth when grasping puncture exactly have certain difficulty, also bring certain misery to the patient thus, the puncture back is also very inconvenient to fixing of puncture needle in addition.
(3) summary of the invention:
The purpose of this utility model is to propose a kind of semi-automatic venipuncture device, makes it can help medical personnel to control the puncture angle and the degree of depth, and has convenient fixed characteristics.
This utility model is finished its invention task by the following technical solutions: it mainly comprises base, fixed support and rotating turret, base is that the centre of platy structure and plate has set bar hole, the fixed support upper articulation rotating turret that is fixedly connected with base, rotating turret one end and fixed support are hinged by jointed shaft, be connected with venipuncture needle on the bottom surface of the other end, the needle point of puncture needle is vertical with needle body to the line of jointed shaft.
During operation, method connects transfusion device and infusion bottle with puncture needle routinely, clamps a fast control valve of transfusion device, aerofluxus; Prick tourniquet, skin degerming.Puncture needle is connected on the bottom surface of rotating turret one end blended rubber cloth and fixes, the perforator base rides on vein blood vessel, and vein blood vessel just in time is revealed in the middle of the bar hole that pedestal sets, and both are parallel, use the immobilization with adhesive tape base.Finger press rotating turret afterbody, the rotating turret arcuate movement, syringe needle can penetrate intravenous, if see blood back, promptly proof punctures successfully, unties tourniquet, unclamps transfusion device and drips fast actuator, with immobilization with adhesive tape rotating turret afterbody, regulates and drips speed, puncture finishes.During puncture, when needle point contact epiderm skin, about 15～20 ° of the angle of cut of needle body and skin, along with the increase of depth of needle, the needle body and the skin angle of cut are more and more littler, and after the set degree of depth of intravasation, needle body is approximate parallel with the blood vessel major axis.
Perforator of the present utility model can help medical personnel to control the needle angle and the degree of depth of puncture, has puncture success rate height, characteristics fast, convenient simultaneously fixing to perforator.
(4) description of drawings:
Accompanying drawing 1 is this utility model structural representation.
Among the figure, 1-base, 2-fixed support, 3-jointed shaft, 4-rotating turret, 5-puncture needle, 6-administration flexible pipe, 7-bar hole.
(5) specific embodiment:
The embodiment that provides is in conjunction with the accompanying drawings further specified its structure:
As shown in Figure 1, this utility model perforator mainly comprises base 1, fixed support 2, rotating turret 4 and venipuncture needle 5, and puncture needle 5 connects transfusion device, infusion bottle by flexible pipe 6.Base 1 is a platy structure, has set bar hole 7 on the base of platy structure, and for appearing vein blood vessel and puncture needle is passed through, the arc protuberance of base one end is for not oppressing vein blood vessel, and the both wings that the other end is overhanging are to be the convenient immobilization with adhesive tape base of using.Fixed support 2 is fixedly connected with base 1, rotating turret 4 one ends are hinged by jointed shaft 3 and fixed support 2, but relative fixed support 2 and base 1 are made arcuate movement, the bottom surface of rotating turret 4 other ends (tail end) is connected with venipuncture needle 5, puncture needle is corresponding to the bar hole of pedestal, needle point can thrust vein blood vessel by bar hole when making arcuate movement, and needle point is vertical with needle body to the line of jointed shaft 3.When rotating turret forwards certain position to, needle point thrusts vein blood vessel and during to both allocations, the tail end of rotating turret and base 1 are adjacent to and play position-limiting action, and rotating turret can not be rotated again.
Claims (1)
1, a kind of semi-automatic venipuncture device, it is characterized in that: mainly include base (1), fixed support (2), rotating turret (4) and venipuncture needle (5), base (1) has set bar hole (7) for the centre of platy structure and plate, fixed support (2) the upper articulation swinging mounting (4) that is fixedly connected with base (1), one end of rotating turret (4) and fixed support (2) are hinged by jointed shaft (3), be connected with venipuncture needle (5) on the bottom surface of the rotating turret other end, the needle point of puncture needle (5) is vertical with needle body to the line of jointed shaft (3).
