Abstract

The invention belongs to a medical transfusion apparatus, more particularly a portable liquid/blood transfusion device, which is characterized by consisting of a transfusion bag, a single-channel plug, a transfusion tube, an adjustment valve, a terminal filter and a needle. This system is internally further provided with a micropump. The device disclosed in the invention has the following advantages of small volume, light weight, simple structure, convenience of operation and safety and comfort in the process of intravenous drip. A patient, who accepts liquid/blood transfusion by using the device, achieves unlimited posture movement and can sit, lie down or walk, so that the portable liquid/blood transfusion device is especially suitable for the emergency treatment of wounded in field disaster and at war.

Description

The portable infusion blood exchange transfusion set

Technical field

The invention belongs to the medical transfusion utensil, particularly a kind of portable infusion blood exchange transfusion set

Give the still common employing pressure reduction of patient's blood transfusion and infusion principle at present, medicine bottle or blood bag are hung formation pressure reduction.This blood transfusion and infusion mode patient needs the fixed position, is crouching on one's sick bed or is being seated on chair.Want defecation as the patient, need nurse or family members to accompany and attend to, very inconvenient.And generation blood back or bulge phenomenon.Particularly the war or the injury first aid of travelling outdoors are more inconvenient.

The present invention has overcome the deficiency of traditional blood transfusion and infusion device, and portable blood transfusion and infusion device has been removed suspension bracket from makes the movable walking of patient freely, removes the blood back bulge phenomenon simultaneously from, the predicament when greatly having alleviated patient's dead point.

The present invention realizes like this, traditional transfusion device length is narrowed down to about the sixth of original length, remove air inlet pipe, dropper makes dual pathways plug into the single channel plug, on tube for transfusion, install the micro electric pump of a charged pool, micro electric pump, ultimate filter, threeway, battery, control valve is contained in the housing that (the small and light volume that can do of fluid and blood transfusion apparatus can be accomplished below 126 cubic centimetres, weight is that 100 grams are following) bottom surface and the nylon sticking belt of this housing fix, the watchband shape that nylon sticking belt is made, the housing of electric pump are made of the transparent plastic of hard (can observe the working condition of electric pump inside, the situation that also can observe medicinal liquid flow velocity speed simultaneously like this.Like this with regard to the effect of alternative dropper)

When actual dead point, the nylon adherent buckle on the shell of micro electric pump is fixed on the wrist, medicinal fluid bag also is fixed on the arm by coat-sleeve with nylon sticking belt.No matter which kind of position each position of health is in, which kind of position dead point syringe needle, medicinal fluid bag are in can both normally be carried out.

The syringe needle place is provided with the safety guard of a hard transparent when dead point, and micro electric pump has hard shell, and tube for transfusion is very short, so the dead point process is that not to be afraid of scratching very safe, comfortable.

Because fluid and blood transfusion apparatus is in the transfusion overall process, medicinal liquid flows out from medicinal fluid bag, in tube for transfusion is inhaled into electric pump.Pumped by electric pump and deliver to syringe needle and flow in the human body, overall process is carried out under totally enclosed environment.There is not the secondary pollution of air.Can not produce bubble yet, both reduce medical personnel's work, reduce injury again the patient.

The portable infusion blood exchange transfusion set, it is made up of two parts, and a part is disposable (every part that can touch medicinal liquid blood is disposable), and another part can be repeatedly used, and two parts can conveniently connect.

Below in conjunction with the detailed explanation of Fig. 1

Fig. 1 is a portable infusion device fundamental diagram

The portable infusion blood exchange transfusion set, pump adopts piston type.Micro electric pump (5) produces vacuum, by tube for transfusion (6) medicinal liquid in the medicinal fluid bag (7) is drawn onto in the electric pump (5).Electric pump (5) pumps medicinal liquid, medicinal liquid process actuator (4), and ultimate filter (3), tube for transfusion (2) arrives syringe needle (1) and enters human body, and goes round and begins again.At last medicinal liquid all is expelled in the human body, finishes whole infusion process.

Claims

1. disposable medical infusing device.

By medicinal fluid bag (7) tube for transfusion (2), (6), control valve (4) ultimate filter (3), syringe needle (1) is formed transfusion system. it is characterized by: in transfusion system, this device of device (perhaps by a such device) that is provided with a band electromotor can make medicinal liquid guarantee to flow to syringe needle (1) liquid pressure simultaneously with a suitable pressure (this pressure is medicinal liquid enters needed by human body by syringe needle pressure), can be because of the relative altitude (the suction journey of micropump is less than ten meters) of syringe needle (1) with medicinal fluid bag (7), distance, the change of the angle of putting and influence normal transfusion.

2. described by right 1, it is characterized by, the energy source of electromotor is supplied with by battery.

3. described by right 1, it is characterized by, be provided with the protective cover of an anti-collision at the syringe needle place.

4. described by right 1, it is characterized by, portable infusion the blood exchange transfusion set be fixed on the wrist with nylon adherent buckle.

5. described by right 1, it is characterized by, portable infusion blood exchange transfusion set's volume is less than 126 cubic centimetres.

6. described by right 1, it is characterized by, the portable infusion blood exchange transfusion set, it is made up of two parts, and a part is disposable (every part that can touch medicinal liquid blood is disposable), and another part can be repeatedly used, and two parts can conveniently connect.

7. described by right 1, it is characterized by, the housing of the micro electric pump among the portable infusion blood exchange transfusion set is transparent, it can substitute the effect of dropper.

8. described by right 1, it is characterized by, the medicinal liquid among the portable infusion blood exchange transfusion set moves (it is exactly syringe needle that medicinal liquid has only an outlet) in totally enclosed system, enter human body through syringe needle, and this design can not produce bubble.

9. described by right 1, it is characterized by, control valve, micropump, ultimate filter, threeway is in a housing.

10. described by right 1, it is characterized by, the micropump among the portable infusion blood exchange transfusion set is with motor-driven, adopts piston type.
