Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an anti-drop infusion apparatus structure.
Background
The infusion is a process of injecting a large amount of injection into a patient from a vein, the injection is packaged in a glass or plastic infusion bottle or bag, and when the infusion apparatus is used, the dropping speed is adjusted through the infusion apparatus to continuously and uniformly enter the vein so as to supplement nutrient substances, blood product supplement colloid and blood volume provided by body fluid, electrolyte and the like.
In the infusion process, an infusion apparatus can be pulled sometimes by an adult patient or a young child, the needle head at the front end of the infusion apparatus is smooth and easy to fall off, when an infusion tube connected with the needle head suddenly receives large pulling force, the infusion apparatus easily falls off from the bottle stopper, so that the patient can not continue infusion, the medicine waste, the environment pollution and the workload of medical workers can be caused, the patient or family members can be frightened, and the infusion time of the patient is prolonged.
Disclosure of Invention
The invention provides an anti-drop infusion set structure, which aims to solve the problem that in the prior art, when an infusion tube connected with a needle is suddenly subjected to large pulling force, the infusion tube is easy to drop from a bottle stopper, so that a patient can not continue infusion.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the utility model provides an anti-drop's transfusion system structure, includes integrated into one piece's last needle tubing, needle tubing and spacing chuck down, spacing chuck is located between needle tubing and the lower needle tubing, go up horizontal passageway and the vertical passageway that sets up mutual intercommunication in the needle tubing, the bottom of vertical passageway link up to in the needle tubing down, horizontal in the passageway is equipped with spacing post, and spacing post is close to and is fixed with elastic adhesive layer between needle tubing lateral wall one end and the horizontal passageway, and spacing post is close to vertical passageway one end and is equipped with elastic component and soft adhesive tape, elastic component is fixed with the lateral wall of vertical passageway, soft adhesive tape is located vertical passageway, and the bottom of soft adhesive tape is connected with actuating mechanism, actuating mechanism can realize the coiling of soft adhesive tape and unreel.
The technical principle and the effect of the technical scheme are as follows:
in the infusion apparatus structure in the scheme, when the stopper of the infusion bottle is not inserted, the soft rubber strip is wound on the driving mechanism, so that the limiting stopper pulls the elastic rubber layer to deform towards the transverse channel and is completely positioned in the transverse channel, and the elastic piece is in a compressed state, thereby not hindering the upper needle head from being inserted into the infusion bottle; and after the upper needle head is inserted into the infusion bottle, the driving mechanism unreels the soft adhesive tape, so that the stored energy of the elastic piece is released, the limiting plug is pulled by the elastic adhesive layer to slide in the infusion bottle, the limiting plug and the elastic adhesive layer expose the transverse channel, and the upper needle tube is difficult to separate from the bottle plug of the infusion bottle due to the blocking effect of the limiting plug when the infusion apparatus structure is pulled downwards, and meanwhile, due to the existence of the elastic adhesive layer, the liquid in the infusion bottle is prevented from permeating into the transverse channel.
Further, actuating mechanism includes that the level rotates the bull stick of connecting on the needle tubing down, is fixed with the reel that is located vertical passageway on the bull stick, and the flexible glue strip can be convoluteed on the reel, and the bull stick is close to lower needle tubing outer wall one end and is equipped with spacing stopper, spacing stopper passes through splined connection with the bull stick, and spacing stopper can break away from the bull stick.
Has the advantages that: like this when spacing stopper and bull stick cooperation, the rotation of bull stick is restricted, and after spacing stopper breaks away from the bull stick, the rotation of bull stick no longer receives the restriction for whole theory of operation is simple understandable.
Further, be equipped with spacing hole on the lateral wall of needle tubing down, spacing hole can hold spacing stopper, and spacing stopper is kept away from and is equipped with the knob on the outer wall of bull stick one end, and the external diameter of knob is greater than the diameter of spacing stopper, still is equipped with the spacing groove that link up with spacing hole on the lateral wall of lower needle tubing, the spacing groove is the polygon, and the knob can block into the spacing groove.
Has the advantages that: after the infusion is accomplished, because usually need separately retrieve infusion structure and infusion bottle, consequently medical personnel can extract the spacing groove with the knob, and the spline section has the part with internal spline cover to be in the same place meshing simultaneously, through rotating the knob like this for soft adhesive tape coils on the reel once more, and after spacing post drove the elasticity glue film and gets back to within the transverse channel, can be smooth extract last needle tubing.
Further, the depth of the knob is larger than that of the limiting groove.
Has the advantages that: thus, a part of the knob is positioned outside the lower needle tube, and the knob is convenient for medical staff to take out.
Furthermore, a plurality of vertical bars are uniformly distributed on the outer wall of the knob.
Has the advantages that: thus, the roughness of the outer wall of the knob is improved, and medical staff can twist the knob better.
Furthermore, a flow channel penetrating through the lower needle tube is arranged in the upper needle tube, and a liquid inlet communicated with the flow channel is formed in the side wall of the upper needle tube.
Has the advantages that: the liquid inlet is arranged on the side wall of the upper needle tube, so that the liquid remained in the infusion bottle can be reduced.
Further, the cross sections of the transverse channel and the vertical channel are both in a circular hole shape.
Has the advantages that: therefore, the limiting plug and the soft rubber strip can move in the limiting plug and the soft rubber strip conveniently.
Furthermore, the transverse channel and the vertical channel are in arc transition connection.
Has the advantages that: thus reducing the friction of the corner to the soft rubber strip.
Furthermore, a film is bonded on the side wall of the upper needle tube, and the film seals the transverse channel.
Has the advantages that: the film can prevent that external dust from entering into because of the elastic glue film warp in the cavity that forms, prevents to produce the pollution, also be in order to make the outer wall of going up the needle tubing be complete shape in addition for go up the better bottle plug of inserting the infusion bottle of needle tubing, and even if this in-process film breaks, also do not have an influence.
Furthermore, the end face of the limiting column, which is close to one end of the thin film, is integrally formed with a sharp, and the sharp end faces the thin film.
Has the advantages that: therefore, in the process that the limiting column moves towards the thin film, the sharp pricks can pierce the thin film, so that the thin film is better broken.
