Abstract

The utility model relates to an enclosed type safety transfusion device. The utility model is the improvement to the existing disposable transfusion utensil. The utility model has a check valve for a spherical body, an air pressure bottle, and a barometer, besides comprising a three-way pipe, a transfusion tube, a murphy's funnel, a needle head, and an air inlet pipe. A pin valve with a cone on the check valve for the spherical body is penetrated in a limiting pipe of the murphy's funnel. One end of the air pressure bottle is provided with an exhaust valve and an air inlet valve, and the other end is provided with the barometer. The air pressure bottle is communicated with the air inlet pipe arranged on the three-way pipe through the exhaust valve on the air pressure bottle. The utility model has the advantages of simple structure and high safety. The conditions that blood inputs back to human bodies and air pollutes liquid medicine can be avoided, the limitation of transfusion conditions of position difference can not be affected, and the quick transfusion can be effectively realized.

Description

The pessimistic securit transfusion device

This utility model relates to a kind of medical pessimistic securit transfusion device, belongs to medical apparatus manufacturing technology field.

Human body is had an intravenous drip and infused is one of traditional effective Therapeutic Method of medical department.Existing disposable transfusion device occurs blood back, air pollution medicinal liquid easily, is subjected to potential difference transfusion condition restriction and can not realizes defectives such as quick transfusion in the first aid because it in use exists, and causes many uses not make and hidden danger to the patient.Learn that from the Chinese Searches of Patent Literature improvement of this infusion set is not rare, but the ubiquity improvement is single, the single problem of effect.Promptly or only consider the minimizing liquid medicine contamination, or only consider blood back when preventing unmanned nurse, have in addition complex structure, be not easy to promote the use of.As No. 97211155.7 patents of Chinese utility model is exactly wherein an example.

Goal of the invention of the present utility model is at many colleagues the improved deficiency of disposable transfusion device to be taken all factors into consideration above-mentioned various factors in one, release a kind of simple and reasonable, avoid human body blood back and air pollution medicinal liquid, use simultaneously and be not subjected to potential difference transfusion condition and environmental limitations, can realize quick transfusion, safe and reliable pessimistic securit transfusion device.

Goal of the invention of the present utility model can be achieved by the following technical programs: this pessimistic securit transfusion device comprises tee T 2, tube for transfusion 3,6, not Fei Shi funnel 4, syringe needle 7, air inlet pipe 12; Simultaneously it also has air-pot 10, air gauge 11 and is made of the spheroid check-valves 5 that also is connected as a single entity successively hollow ball 13, sphere teabowl with a cover 14, needle-valve 15.Needle-valve 15 on the spheroid check-valves 5 is installed in the position-limiting tube 16 of Fei Shi funnel 4 not; One end of air-pot 10 is respectively equipped with air bleeding valve 8, intake valve 9, and the other end is equipped with air gauge 11, and air-pot 10 is connected with air inlet pipe 12 on being contained in tee T 2 by the air bleeding valve on it 8.

This utility model advantage compared with prior art is conspicuous: the first, owing to the set barometric special-purpose transfusion air-pot of being with, adopt high-quality transfusion gas, changed the working method that transfusion device in the past utilizes the naturally air to infuse, the pollution of having avoided surrounding air that medicinal liquid is produced.The second, the effect of air-pot shows that also it has replaced the potential difference infusion model of transfusion device in the past with the air pressure infusion model, has overcome the restriction of environmental condition to human transfusion, is particularly conducive to battlefield and field work and takes urgent emergency measures.Three, do not installed check-valves additional in the Fei Shi funnel at traditional transfusion device, dependable performance has prevented old-fashioned transfusion device decompression and blood back problem of causing when the unmanned nurse of patient.Four, because the scalable effect of air bleeding valve 8 on the air-pot makes the novel quick transfusion problem that can realize smoothly in the first aid of this reality.

Accompanying drawing and drawing are described as follows:

Fig. 1 is an overall structure sketch map of the present utility model;

Fig. 2 is a user mode sketch map of the present utility model.

Wherein:

1-infusion bottle, 2-tee T 3,6-tube for transfusion

4-not Fei Shi funnels, 5-check-valves, 7-syringe needle

8-air bleeding valve, 9-intake valve, 10-air-pot

11-air gauge, 12-air inlet pipe, 13-hollow ball

14-sphere teabowl with a cover, 15-needle-valve, 16-stop

Embodiment: this description the 5th part and in conjunction with the accompanying drawings 1-2 provided this practical full implementation example, so no longer repetition here.What need supplementary notes is that the operation principle of this transfusion device is: when in the Fei Shi funnel not liquid being arranged, hollow ball floats, and needle-valve is opened, and liquid begins to make a bet; After liquid was totally lost, hollow ball descended, and needle-valve is closed, and small amount of liquid is not left because of the effect of position-limiting tube in Fei Shi funnel bottom simultaneously, and at this moment the sphere teabowl with a cover edge that descends immerses liquid, reliably seals by liquid; After hollow ball descended simultaneously, with not also driving fit of Fei Shi hopper walls, air pressure all acted on the hollow ball, has guaranteed the sealing of transfusion device.With traditional transfusion device relatively, the whole process of patient's infusion treatment is to be in the process of a relative closure to carry out, the pressure power that uses is from the gas pressure bottle through intensive treatment such as concentrated sterilization, filtration, oxygenations, it has not only improved infusion treatment effect and safety coefficient greatly, and not having a press operation requirement, promptly is that the sick and wounded on the stretcher also can guarantee to infuse in advancing reliable and securely.The check-valves 5 of being totally lost behind the liquid cuts out under the effect of air pressure automatically, makes transfusion device and blood pressure keep relative stability balance and effectively prevent blood back.Appearance of the present utility model will improve medical level and play positive role normalization, the scientific management of medical department.
