Abstract

A novel medical infusion set comprises a puncture device (which is connected with an infusion tube and an air inlet tube), the infusion tube, a flow rate adjustor, a dropper (a flow rate observation window), a floater (a shutoff valve), a latex tube and a needle head, wherein the puncture device of the infusion set is inserted into an infusion container to be communicated with the infusion tube and the air inlet tube; the infusion container is placed at a high position, so that liquor can be introduced into the infusion tube and the dropper under the action of the gravity, and the height of the liquor level in the dropper is two thirds of that of the dropper; the floater is placed in the dropper and floats on the level of the liquor, and the height of the floater exposed out of the liquor level is one third of the diameter of the floater; after the air bubbles in the infusion tube at the lower end of the dropper are discharged clean, and the needle head is punctured into the vein blood vessel of a patient, the flow rate of the liquor can be adjusted, and the infusion set can infuse normally; and when the infusion is finished basically, and the liquor level is reduced to be close to the bottom of the dropper, the floater blocks the liquor outlet at the bottom of the dropper under the action of the gravity, so that the liquor can not flow into the infusion tube at the lower end continuously, and the height of the liquor level is kept so as to prevent blood in the infusion tube from backflow.

Description

A kind of new medical transfusion device

Technical field

This utility model relates to a kind of new medical transfusion device; Relating to a kind of especially is to prevent tube for transfusion generation blood backflow (hereinafter to be referred as blood back) phenomenon in patient's infusion process the doctor, avoids solidifying the transfusion device that causes tube for transfusion to stop up because of tube for transfusion blood back pipe inner blood.

Background technology

At present; The conventional medical transfusion device that people produce and use is with the perforator insertion infusion vessel of transfusion device, makes infusion vessel and tube for transfusion and air inlet pipe UNICOM; Infusion vessel places eminence through action of gravity medicinal liquid to be introduced tube for transfusion and dripped kettle (bucket); Drip kettle giving drugs into nose liquid level and be about kettle at high 2/3 o'clock, after the air bubble in the tube for transfusion of kettle lower end is dripped in emptying, syringe needle is thrust patient's vein blood vessel adjusting flow get final product normal infusion.But, many times in infusion process, cause blood back in the tube for transfusion owing to managing and protecting reason such as improper.Though the residue medicinal liquid can prevent the air admission human body in the pipe; But can bring fear to the patient,, be easy to cause the backflow blood coagulation to stop up tube for transfusion because the latex tubing that is connected with syringe needle is thinner; Transfusion can't normally be carried out, must Repeated Acupuncture bring misery when infusing continuously to the patient.

Summary of the invention

In order to overcome the conventional medical transfusion device in infusion process, cause and occur the blood back phenomenon in the tube for transfusion owing to managing and protecting reason such as improper, this utility model provides a kind of new medical transfusion device, makes transfusion device in infusion process, avoid tube for transfusion blood back phenomenon to take place.

The medical Transfusion device that this utility model provides; Comprise perforator (being communicated with tube for transfusion and air hose), tube for transfusion, flow regulator, drip kettle (flow observation window), float (stop valve), latex tubing and syringe needle; Wherein, Be the perforator of transfusion device to be inserted infusion vessel it is communicated with tube for transfusion and air inlet pipe, infusion vessel places eminence through action of gravity medicinal liquid to be introduced a tube for transfusion and a kettle, a kettle giving drugs into nose liquid level be about kettle high 2/3; Float has placed in the kettle and has swum on the medicinal liquid face; Float exposes medicinal liquid face height and is about 1/3 of float diameter, after the air bubble in the tube for transfusion of kettle lower end is dripped in emptying, syringe needle is thrust regulate medicinal liquid flow in patient's vein blood vessel and get final product normal infusion.Accomplish the medicinal liquid face and drop to when dripping the kettle bottom when transfusion is basic, float blocks under action of gravity and drips a kettle bottom medicine liquid outlet, makes medicinal liquid can not continue to flow into the lower end tube for transfusion, keeps liquid level to prevent blood back phenomenon in the tube for transfusion.If need to drip in the medicinal liquid input patient body in the tube for transfusion of kettle lower end, only need float to be departed from and drip kettle bottom medicine liquid outlet through manual intervention.

The beneficial effect of this utility model is; Utilize float under action of gravity; When the medicinal liquid face drops to approaching kettle bottom, utilize float to block and drip a kettle bottom medicine liquid outlet, make medicinal liquid can not continue to flow into lower end tube for transfusion maintenance liquid level; Avoid occurring blood back phenomenon in the tube for transfusion, prevent to stop up because of blood coagulation causes tube for transfusion.

The specific embodiment

Specific embodiment to this utility model is elaborated below with reference to accompanying drawings.

Among Fig. 1; Be the perforator of transfusion device 3 to be inserted infusion vessels 1 it is communicated with tube for transfusion 5 and air inlet pipe 2, infusion vessel 1 places eminence through action of gravity medicinal liquid to be introduced a tube for transfusion 5 and a kettle 6, kettle 6 a giving drugs into nose liquid level be about kettle high 2/3; Float 7 places in the kettle 6 and swims on the medicinal liquid face; It exposes liquid level and is about 1/3 of float 7 diameters, after the interior air bubble of kettle 6 lower end tube for transfusions 5 is dripped in emptying, syringe needle 14 is thrust in patient's vein blood vessel; Regulate medicinal liquid flow through flow regulator 4, medicinal liquid flows under the influence of gravity in patient's body and gets final product normal infusion.

Among Fig. 2; It is 2/3 highly time of float 7 diameters that medicinal liquid face height in dripping kettle 6 is reduced to apart from the height that drips kettle 6 bottom medicine liquid outlets; Float 7 blocks under action of gravity and drips kettle 6 bottom medicine liquid outlets, makes medicinal liquid can not continue to flow into lower end tube for transfusion 5 to keep liquid level, makes medicinal liquid face height of level line 11 when accomplishing transfusion; All the time be higher than people's position height of level line 12 when accomplishing transfusion, keep the two ends height difference H ₂13, keep two ends pressure reduction and prevent to cause the blood backflow phenomenon.

In sum; This utility model provides a kind of new medical transfusion device, and this medical Transfusion device has reasonably solved tube for transfusion blood back problem, has avoided the fear of bringing to the patient because of the tube for transfusion blood back; Reduce the misery of bringing to the patient because of Repeated Acupuncture, improved the safety of infusion process greatly.
