Description

The high-order negative pressure transfusion utensil of flexible plastic

(1) technical field:

This utility model relates to medical infusion device, is specially the high-order negative pressure transfusion utensil of a kind of flexible plastic.

(2) background technology:

Venous transfusion is a kind of Therapeutic Method of commonly using.

Traditional infusion method is that infusion bottle is placed in to certain height, utilizes the gravity drop of liquid to overcome the human vein blood pressure, and medicinal liquid is entered in human vein through syringe needle; For the inside and outside differential pressure of balance infusion bottle, adopted the tube for transfusion with air inlet pipe.

For avoiding (in air) antibacterial, microorganism and the harmful substance pollution to medicinal liquid in infusion process, designed the sealed transfusion device in prior art, as notification number " a kind of all-sealed infusion set " patent of invention that is CN2194730Y and application number " Full closed transfusion device " utility model patent that is 200520104761.8.

Described " a kind of all-sealed infusion set " (CN2194730Y) patent of invention adopts flexible material to make transfusion bag, by tube for transfusion, medicinal liquid is inputted in human body, this infusion set is without air inlet pipe, outflow along with medicinal liquid, produce negative pressure in transfusion bag, atmospheric pressure compressing transfusion bag, discharge medicinal liquid the input human body smoothly.

The problem existed: medicinal liquid can't drain, and the transfusion bag distortion is irregular, the output situation that is difficult to observe amount of infusion.

Separate upper cavity and lower chamber in the infusion bottle of described " Full closed transfusion device " (200520104761.8) utility model patent, transfusion bag is contained in lower chamber, infusion bottle is provided with and communicating pipe is communicated with upper cavity and lower chamber, during use up, fill with water in lower chamber, in infusion process, along with constantly reducing of transfusion bag volume, the water of upper cavity constantly enters lower chamber, fill the space that the transfusion bag volume reduces, keep continuing of transfusion.

The problem existed: complex structure, use inconvenience, cost is high.

(3) utility model content:

For the deficiencies in the prior art, the utility model proposes a kind of high-order negative pressure transfusion utensil of flexible plastic of hermetically sealed transfusion, its order be simplified structure, easy to use, be easy to observe.

Can realize the high-order negative pressure transfusion utensil of flexible plastic of above-mentioned purpose, comprise the infusion bottle of reversal of the natural order of things and with the tube for transfusion of flow control valve, the perforator of described tube for transfusion one end inserts the bottleneck of infusion bottle, difference is that described infusion bottle is soft plastic bottle, described soft plastic bottle has waveform or the zigzag bottle limit that can make the bottle axial shrinkage, on described perforator without air inlet pipe.

In infusion process, along with the output of medicinal liquid, in bottle, a negative pressure increases, under the atmospheric pressure effect, the compressed and axial shrinkage of bottle, its amount of contraction is synchronizeed with amount of infusion, amount of infusion the number very clear by the amount of contraction of observation bottle.

For being easy to blowing, conventional circle or the two kinds of doleiforms of flat of adopting of the bottle of described soft plastic bottle.

Several orthobaric volumes of described soft plastic bottle are 100ml, 250ml or 500ml.

Described flow control valve comprises valve body, pressure pipe wheel and limiting card, described pressure pipe wheel slides and is located in the sliding tray of offering on valve body, described limiting card is placed in sliding tray, the indent nock of limiting card front end props up pressure pipe wheel rear portion, the external tooth of limiting card both sides engages with the internal tooth of sliding tray both sides, prevent pressure pipe wheel loosening and random adjust flux backward with this, keep amount of infusion stable.

Described limiting card is connected on valve body with soft band.

Advantage of the present utility model:

1, the high-order negative pressure transfusion utensil of this utility model flexible plastic is Full closed transfusion device, can effectively prevent cross infection, and blood back, not safe and reliable.

2, this utility model transfusion situation is directly perceived, by the deflection of soft plastic bottle can know amount of infusion the number, be easy to observe.

3, soft plastic bottle of the present utility model uses rear axial contraction, and volume reduces, and is convenient to collection and treatment.

4, flow control valve of the present utility model has pressure pipe wheel limit function, and the pressure pipe wheel can not arbitrarily be regulated, and amount of infusion is stable.
