Abstract

The utility model relates to a multifunctional disposable infusion device with negative pressure. A negative-pressure suction pipe is communicated on an infusion pipe connected with one end of a needle head, one end of the negative-pressure suction pipe is communicated with the infusion pipe, the other end is connected with a negative-pressure device, and a negative-pressure adjuster is also sheathed on the negative-pressure suction pipe. An injection person can easily determine whether the needle head is penetrated into a patient's vein or not by adopting the structure, the patient's pain is lightened, and simultaneously the utility model can also be used as a puncture needle.

Description

Multifunctional disposable negative pressure transfusion device

This novel a kind of medical apparatus and instruments, transfusion device of particularly a kind of transfusion or puncture usefulness of relating to.

Transfusion and puncture promptly are a kind of medically commonly used to patient's route of administration, be again a kind of medical diagnosis on disease and treatment means, in clinical, use very extensive, and the injector wants all ages and classes, and the patient of different body constitution accomplishes to hit the nail on the head, once with regard to the accurate vein that penetrates of energy, it is not a simple thing, need certain experience and technical ability, particularly often fault rate is higher for the medical personnel of basic unit and broad masses, and the injector is difficult to know whether syringe needle has penetrated vein.

This novel purpose is: design a kind of injector of order and readily appreciate that whether syringe needle has penetrated vein, thereby can alleviate patient suffering's transfusion device once with regard to the accurate vein that penetrates of energy, this transfusion device can be used for transfusion and can be used for various punctures again simultaneously.

To achieve these goals, this is novel to have adopted following structure: on the tube for transfusion that connects syringe needle one end, be communicated with a negative pressure straw, this negative pressure straw one end communicates with tube for transfusion, connect a negtive-pressure implement on the other end, and also be with a draft regulator on this negative pressure straw.

Adopt as above structure, can know easily by negative pressure straw whether syringe needle penetrates patient's vein, not only alleviated patient's misery but also alleviated injector's pressure at heart, owing to increased negative pressure straw, also increased the use of transfusion device simultaneously, make transfusion device integrate transfusion and puncture, the injector utilizes the blood back situation of observing negative pressure straw, inserting needle accurately, and can instruct the traveling in lumen of vessels of threading a needle, and unlikely passing; This transfusion device also can be done the puncture needle use simultaneously.

Illustrate below in conjunction with example:

Fig. 1 is this novel three-dimensional structure diagram.

As shown in Figure 1, tube for transfusion 3 is one-shot forming with negative pressure pipe 6, and is interconnected.

Be with an infusion regulator 9 on tube for transfusion 3, also have filter 2 liquid dripping kettles 1 on the tube for transfusion 3, this part-structure is a known technology, no longer describes in detail.

Negative pressure straw 6 in that tube for transfusion 3 is communicated with is connected with negtive-pressure implement 4 by link 5, and negtive-pressure implement 4 is the air bag of high resilience material manufacture, also have on the negative pressure straw 6 one with tube for transfusion 3 on identical infusion regulator 7.

When transfusion is used, the transfusion preparatory stage of tube for transfusion 3 parts is all identical with prior art, it only is the infusion regulator 7 of closing after on negative pressure straw 6, the air in the negtive-pressure implement 4 being squeezed a part on the negative pressure pipe 6, after preparation is carried out, both pinprick can be gone into patient's vein, infusion regulator 7 changes vacuum magnitude and speed on the negative pressure straw 6 by regulating, observe the blood back amount, can determine easily whether syringe needle 8 has penetrated in the patient's vein, all turn back to the blood on the negative pressure straw 6 in the blood vessel at last, close the infusion regulator 7 on the negative pressure straw 6, the infusion regulator of opening on the tube for transfusion 39 both can be infused normally.

When in puncture, using, close tube for transfusion 3, whether successful by observing the material that refluxes in the negative pressure straw 6 with definite puncture, negtive-pressure implement 4 be can take off at last and drawing liquid fluid injection or pressure measurement carried out, also can insert the lumbar anesthesia liquid injection pipe, state the back extraction and thread a needle, the paracentesis post processing both can routinely.

Claims

1. multifunctional disposable negative pressure transfusion device, be by tube for transfusion, infusion regulator, compositions such as liquid dripping kettle, it is characterized in that: on the tube for transfusion that connects syringe needle one end, be communicated with a negative pressure straw, this negative pressure straw one end communicates with tube for transfusion, connects a negtive-pressure implement on the other end, and also is with a draft regulator on this negative pressure straw.
