Abstract

The utility model relates to a novel transfusion device which is characterized in that the utility model is formed by orderly connecting a bottle inserting needle with a drip tube, a flow control valve and a puncture needle head with a three-way tube by conduits, wherein, the puncture needle head with the three-way tube is integral. A through hole of one end of the three-way tube is connected with the conduits, and a through hole of another end of the three-way tube is a medicine feeding port. A sealing plug is arranged on the medicine feeding port. Since the utility model has the structure, the utility model has the advantages of high safety, convenience and simple and precise control. The three-way tube on the puncture needle head is provided with the medicine feeding port, which causes physic liquor to directly enter a patient body.

Description

A kind of novel infusion device

A kind of medical apparatus, the particularly a kind of novel infusion device of relating to of the present utility model.

There is not airport on the needle for inserting bottle of existing infusion set, be that an air inlet pipe and Guan Shangwu switch are singly arranged, do not need during the drop bottled medicinal liquor air inlet pipe is blocked and can be used, but when drop plastic bag powder charge liquid, air inlet pipe must be blocked, because of there not being switching device on the air inlet pipe, can only a knot will be made a call on the air inlet pipe, when changing medicine bottle, need again knot is untied, use very inconvenient.Simultaneously, all do not have dosing mouth during existing piercing needle, inconvenient dosing and medicinal liquid are not in time to enter in patient's body later treatment.

The purpose of this utility model is to provide a kind of novel infusion device, airport is arranged on its needle for inserting bottle and can cover the switching that control air by control, and tee T has dosing mouth that medicinal liquid is directly entered in patient's body on the piercing needle.This utility model uses safe ready, and control is accurately simple.

The purpose of this utility model is achieved in that a kind of novel infusion device, it is characterized in that: be to be connected in sequence by conduit by the needle for inserting bottle that has dropper, flow control valve and the piercing needle that has a tee T; The described piercing needle that has tee T is an integral type, an end port connecting duct of tee T, and the other end port of tee T is a dosing mouth, and blocking is arranged on it.The described needle for inserting bottle that has dropper is to be made of needle for inserting bottle head, air filtering core and control lid and the dropper that has an air suspension plug, the effect of air suspension plug is, when in the dropper during no liquid air suspension plug close automatically and prevent backflow of blood, it is an integral structure; Wherein the needle for inserting bottle head is the three-port type structure, the transverse section in three holes is arranged as " product " font, intermediary hole is that airport is communicated with the air filtering core of bottom, described air filtering core has the control lid, in the dropper of two holes of both sides for the straight-through bottom of injection ostium, airport is not communicated with mutually with the injection ostium.

The utlity model has safe ready owing to there is above-mentioned structure to make, control is accurately simple, and tee T has dosing mouth that medicinal liquid is directly entered in patient's body on the piercing needle.

Below in conjunction with drawings and Examples this utility model is further described.

Fig. 1: overall structure figure of the present utility model and embodiment;

Fig. 2 (a): the overall structure perspective view and the embodiment of this utility model needle for inserting bottle head.

Fig. 2 (b): the vertical view of this utility model needle for inserting bottle head.

Fig. 3: be the side view of Fig. 2.

Among the figure: the 1-needle for inserting bottle, 11-needle for inserting bottle head, the 12-air filtering core, 13-controls lid, 14-air suspension plug, 15-dropper, 111-injection ostium.The 112-airport; The 2-flow control valve; The 3-piercing needle, 31-syringe needle, 32-dosing mouth, 33-blocking, 34-tee T.

Referring to Fig. 1-Fig. 3: a kind of novel infusion device is characterized in that: be to be connected in sequence by conduit by the needle for inserting bottle 1 that has dropper, flow control valve 2 and the piercing needle 3 that has a tee T; The described piercing needle 3 that has tee T is integral type, and an end port connecting duct of tee T 34, the other end port of tee T 34 are dosing mouth 32, and blocking 33 is arranged on it.The described needle for inserting bottle 1 that has dropper 15 be by needle for inserting bottle head 11, air filtering core 12 and control cover 13 and the dropper 15 that has an air suspension plug 14 constitute, the effect of air suspension plug is, when in the dropper during no liquid air suspension plug close automatically and prevent backflow of blood, it is an integral structure; Wherein needle for inserting bottle head 11 is the three-port type structure, the transverse section in three holes is arranged as " product " font, intermediary hole is that airport 112 is communicated with the air filtering core 12 of bottom, described air filtering core 12 has control and covers 13, two holes of both sides are that airport 112 is not communicated with mutually with injection ostium 111 in the dropper 15 of injection ostium 111 straight-through bottoms.
