Abstract

The utility model relates to an anti-contamination blood transfusion apparatus, relating to medical and sanitary devices. The utility model is composed of a needle head with thick diameter, a three-way connection pipe, an exhaust pipe, a blocking cover, etc., wherein, the upper end of the three-way connection pipe is provided with a needle head with the hick diameter, one side of the three-way connection pipe is an induction passage, the lower end of the three-way connection pipe is an infusion passage, and thus a blood transfusion and the exhaust pipe are combined into integration. The utility model has the advantages that contaminated opportunities caused by the storing of the exhaust pipe are reduced; the insertion and the extraction of the exhaust pipe are replaced by the opening and the closing of the blocking cover, and operation is convenient; owing to a needle head with the thick diameter is only used, the possibility of the phenomenon that a needle hole is easy to block by rubber particles is reduced when the needle head is inserted into a rubber bottle cork; the production cost of a blood transfusion apparatus is reduced.

Description

Anti-pollution blood exchange transfusion set

This utility model relates to medical device, particularly the blood transfusion medical device.

At present, the medical department of China generally all uses disposable transfusion set when transfusing blood to the patient, and it has advantages such as operation is comparatively simple.But, existing disposable transfusion set, its blood transfusion tube and exhaustor are isolating, this not only uses inconvenience, also is unfavorable for anti-pollution.

We know, when blood transfusion, are the quality of guaranteeing to transfuse blood, and need an amount of isotonic saline solution of input earlier, transfuse blood then, import an amount of isotonic saline solution at last again.Because isotonic saline solution adopts glass bottle, so during defeated isotonic saline solution, need use exhaustor, atmosphere is compressed into air by exhaustor in bottle, thereby gas has certain pressure on guaranteeing in the bottle.And be packed in bag usually during blood storage, so during blood transfusion, need not in bag, charge into gas, thereby not use exhaustor.Existing blood transfusion process is as follows: hang up the isotonic saline solution bottle, behind 2% iodine tincture and 70% alcohol disinfecting bottle stopper, the particle size syringe needle of blood transfusion tube and the particle size syringe needle of exhaustor are inserted the isotonic saline solution bottle stopper simultaneously to the syringe needle root, import an amount of isotonic saline solution.Hang up storage blood bag then, the blood transfusion tube that is inserted on the isotonic saline solution bottle stopper is pulled up, exhaustor and isotonic saline solution are temporarily placed preservation, then blood transfusion tube particle size syringe needle are inserted storage blood bag, begin blood transfusion.When waiting to store blood in the blood bag and being about to be totally lost, blood transfusion tube particle size syringe needle is extracted, inserted simultaneously in the isotonic saline solution bottle stopper, import an amount of isotonic saline solution, make every effort to the blood in the blood transfusion tube all is totally lost with exhaustor particle size syringe needle.

As seen, adopt existing disposable transfusion set to be patient's blood transfusion, exhaustor will be saved in blood in the storage blood bag back reuse of being totally lost, and exhaustor will stop considerable time in air.In 200 milliliters of grates of minimum transfusion volume, need 2 hours approximately.And general transfusion volume all surpasses 200 milliliters, and therefore, exhaustor may need to place 4 hours or the longer time.Might make exhaustor in air, form pollution like this, thereby bring unnecessary misery to patient easily because of exposing for a long time.

In addition, because separating of exhaustor and blood transfusion tube is therefore when concrete operations, not easy yet.

The purpose of this utility model is, a kind of anti-pollution blood exchange transfusion set is provided, because its blood transfusion tube and exhaustor be integrated, thereby can reduce opportunities for contamination in the blood transfusion process, and have advantages such as easy to use, low cost of manufacture.

The purpose of this utility model realizes by following scheme: anti-pollution blood exchange transfusion set's upper end is a particle size syringe needle, the particle size syringe needle connects three-limb tube down, one side of three-limb tube connects an exhaustor, the termination of exhaustor connects a blocking cap, the lower end of three-limb tube connects a short tube, and short tube is communicated with hemofilter, and hemofilter connects long tube, long tube is provided with actuator, and long tube is taken over by syringe needle and is connected with injection needle.

Compare with existing disposable transfusion set, this utility model has increased a three-limb tube, and only there is a particle size syringe needle upper end of three-limb tube, and a side is an inlet channel, and the lower end is an infusion channel, thereby blood transfusion tube and exhaustor are integrated.

Use blood transfusion process of the present utility model as follows: to hang up the isotonic saline solution bottle, behind 2% iodine tincture and 70% alcohol disinfecting bottle stopper, take out anti-pollution blood exchange transfusion set, open the blocking cap (at this moment exhaustor works) on the exhaustor, the particle size syringe needle is inserted the isotonic saline solution bottle stopper to the syringe needle root, import an amount of isotonic saline solution.Hang up storage blood bag then, the particle size syringe needle is extracted from the isotonic saline solution bottle stopper, cover blocking cap (at this moment exhaustor is just inoperative), then the particle size syringe needle is inserted storage blood bag, begin blood transfusion.When waiting to store blood in the blood bag and being about to be totally lost, blood transfusion tube particle size syringe needle is extracted, opened blocking cap (at this moment exhaustor works), again the particle size syringe needle is inserted in the isotonic saline solution bottle stopper, import an amount of isotonic saline solution, make every effort to the interior blood of blood transfusion tube all is totally lost.

Because this utility model is integrated blood transfusion tube and exhaustor, when failing isotonic saline solution the blocking cap on the exhaustor is opened, exhaustor is worked; During blood transfusion blocking cap is covered, make exhaustor inoperative, thereby substitute existing disposable transfusion set fully.It has the following advantages: 1, do not have the storage problem of exhaustor, thereby reduced the chance of the pollution that causes because of depositing of exhaustor; 2, by the folding of blocking cap substituted exhaustor insertion, extract, easy and simple to handle; 3, because of only using a particle size syringe needle, make when the particle size syringe needle inserts bottle closure of rubber, the probability that easily causes rubber grain to stop up the phenomenon of pin hole has reduced half; 4, since being integrated of exhaustor and blood transfusion tube reduced blood exchange transfusion set's manufacturing cost, thereby helped improving social benefit.

Below in conjunction with accompanying drawing this utility model is further described.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, particle size syringe needle (1) connects three-limb tube (2) down, one side of three-limb tube (2) connects an exhaustor (3), the termination of exhaustor (3) connects a blocking cap (4), the lower end of three-limb tube (2) connects a short tube (5), and short tube (5) is communicated with hemofilter (6), and hemofilter (6) connects long tube (7), long tube (7) is provided with actuator (8), and long tube (7) is taken over (9) by syringe needle and is connected with injection needle (10).

Three-limb tube of the present utility model (2) can form an integral body with exhaustor (3), short tube (5), and blocking cap (4) is connected on the exhaustor (3), can open or jam-pack exhaustor (3).
