Abstract

A cut needle for a transfusion bottle comprises a transfusion needle, an aeration needle and a skeleton, wherein the skeleton is integrally formed by two parallel circular needle-fixed cases with a certain distance. The transfusion needle and the aeration needle are fixed by the skeleton, and the lower parts of the transfusion needle and the aeration needle are encased by the needle-fixed cases to form a transfusion tube connector and an aeration tube connector, the aeration needle is higher than the transfusion needle upwards. The cut needle for a transfusion bottle produces no air plug in transfusion, has advantages that the utility model is labor-saving to push and pull and little in the damage to the bottle, and liquid does not leak in case of repeatedly pushing and pulling the needles and has the characteristics that the utility model is compact in structure and easy to pack.

Description

The transfusion device needle for inserting bottle

Technical field:

This utility model relates to a kind of transfusion device needle for inserting bottle, inserts the infusing medicine bottleneck when being used to infuse, and ventilates and draws medicinal liquid.

Background technology:

At present, the transfusion device needle for inserting bottle that uses clinically mainly contains split type and monoblock type two classes.Split type is transfusion needle, air needle is independent separately, non-integrative-structure, because the transfusion needle of split type transfusion device needle for inserting bottle, air needle length is identical, and relative position is uncertain, so, during clinical practice, can occur that transfusion needle mouth and air needle mouth are in sustained height and spacing is less or the situation of transfusion needle mouth directly over the air needle mouth, the bubble that entered by air needle this moment enters the transfusion needle mouth easily, makes water in the tube for transfusion, gas causes the interior liquid level of Murphy type burette to drop to nothing very soon with advancing, make water by tube for transfusion, gas is with advancing blood vessel, cause air embolism,, can jeopardize patient's life security if observation is untimely.Monoblock type is the form that transfusion needle, air needle are fixed together, and is divided into draw point monoblock type and plastic monoblock formula again.The draw point monoblock type: transfusion needle, air needle do not have the gap and since two pins between with the bottle stopper loose contact, be prone to the phenomenon of leakage, both had potential safety hazard, waste medicinal liquid again; The plastic monoblock formula: because plastics needle for inserting bottle diameter is bigger, bottle stopper is bigger to its resistance, makes the plug effort, and the damage to bottle stopper simultaneously is also bigger, changes liquid as need, when needing to insert bottle stopper repeatedly, easily makes bottle stopper impaired, the phenomenon of leakage occurs.

Summary of the invention:

The purpose of this utility model provides a kind of transfusion device needle for inserting bottle, does not produce aeroembolism, and plug is laborsaving,, repeatedly plug pin no leakage little to the bottle stopper damage, makes things convenient for the medical worker to operate.

The purpose of this utility model realizes as follows: this transfusion device needle for inserting bottle relates to transfusion needle and air needle, and transfusion needle, air needle keep at a certain distance away and be fixed together by skeleton is parallel.

The height that air needle makes progress is higher than transfusion needle, and the air that enters in the medicinal liquid bottle from air needle when making transfusion is unlikely to enter transfusion needle.

Skeleton is to have the whole formation of the solid needle guard of two parallel circles that keep at a certain distance away on the disking body, transfusion needle, air needle end portion are inclusive in the solid needle guard, Gu the diameter of needle guard is identical with split type transfusion needle or air needle with physical dimensions such as height, convenient tube for transfusion and the breather installed, disking body partly is convenient to the operator and is grasped.

The advantage that this transfusion device needle for inserting bottle has: transfusion needle and air needle have spacing, the inclined-plane of transfusion needle mouth and air needle mouth can be opposing, and infusion needle is lower than the height of vent needle, because of gas up, so gas can not enter infusion needle, so can not produce aeroembolism; The syringe needle diameter is less, and vent needle can at first penetrate bottle stopper than length, and bottle stopper is less to its resistance, and is also less to the damage of bottle stopper, has laborsaving, little to bottle stopper damage, the without leakage characteristics of plug pin repeatedly of plug; Compact conformation has and is convenient to the advantage that clinical contact pin is exerted oneself, is easy to pack.

Description of drawings:

Accompanying drawing is the front view of this utility model transfusion device needle for inserting bottle.

The specific embodiment:

With reference to accompanying drawing, this transfusion device needle for inserting bottle is a monoblock type, is made of transfusion needle 2, air needle 3 and skeleton 1.The solid needle guard of two parallel circles that keep at a certain distance away is whole to be constituted skeleton 1 in order to have on the disk, be made of plastics, transfusion needle 2, air needle 3 are fixed by skeleton 1, transfusion needle 2, air needle 3 end portions are inclusive in the solid needle guard, form tube for transfusion interface 5 and breather interface 4, be respectively applied for tube for transfusion 2 and breather 3 are installed.Transfusion needle 2, air needle 3 keep at a certain distance away, and generally are about 4-8mm; Air needle 3 upwards is higher than transfusion needle 2, and it is proper generally to be about 3-8mm.

Claims (3)

1, a kind of transfusion device needle for inserting bottle relates to transfusion needle, air needle, it is characterized in that: transfusion needle (2), air needle (3) keep at a certain distance away by skeleton (1) secured in parallel together.

2, transfusion device needle for inserting bottle according to claim 1 is characterized in that: the height that air needle (3) makes progress is higher than transfusion needle (2).

3, transfusion device needle for inserting bottle according to claim 1 is characterized in that: the solid needle guard of two parallel circles that keep at a certain distance away is whole to be constituted skeleton (1) in order to have on the disking body, and transfusion needle (2), air needle (3) end portion are inclusive in the solid needle guard.
