Abstract

The utility model discloses a disposable transfusion apparatus with a floater plug, which belongs to the field of medical equipment. The floater plug is added to the inner lower portion of a drip cup of the transfusion apparatus, and a partition board with a connection function is disposed in the middle of the transfusion apparatus. The disposable transfusion apparatus with the floater plug eliminates bubbles, stops blood backflow, and can automatically terminate transfusion.

Description

A kind of disposable transfusion device with the float plug

Technical field

This utility model belongs to the medical device field

Background technology

The disposable transfusion device that uses at present is owing to rock, and flow velocity is too fast, makes luxuriant Fei Shi drip kettle and might form a small amount of bubble, and the danger of input human body is arranged.When adding medicinal liquid, also might form a small amount of bubble, the danger of input human body is arranged.Transfusion device is not in time got pin, might blood back.

The utility model content

This utility model can solve medicinal liquid when being totally lost soon, stops transfusion automatically, prevents blood back, prevents the danger of bubble input human body.Its composition has: 1. intravenous needle; 2. helmet: 3. infusion tube; 4. liquid medicine filter; 5. medicine speed actuator; 6. drip kettle; 7. the subglobose float plug that last lower shaft is arranged; 8, bottle plug puncture unit; 9, air filter; 10. the center is porose. play the dividing plate of anastomosis.

The subglobose float plug of last lower shaft is arranged in this kettle and drip the disposable transfusion device that there has been the porose dividing plate of interconnect function at the kettle middle part, float plug 7 is contained in and drips in the kettle 6.When infusing, float rises beyond the Great Wall, heads on the dividing plate of anastomosis.Medicinal liquid is infused to dirty.When tube for transfusion had bubble, because dividing plate, bubble can rise to and drip kettle top, stores, and prevented bubble input human body.When medicinal liquid was totally lost, the float plug leaned on self gravitation and difference force because buoyancy reduces, and overcomes viscous force, blocked and dripped the kettle lower end, stoped air flows downward, overcame the entering human body.Because the gravity and the liquid level difference force of float plug 7 can stop blood back.

Description of drawings

Below in conjunction with accompanying drawing and embodiment, this utility model is described further, identical numbering is represented same parts or position among the figure.

Fig. 1 is a kind of sketch map of the disposable transfusion device with the float plug.1. intravenous needle; 2. helmet: 3. infusion tube; 4. liquid medicine filter; 5. medicine speed actuator; 6. drip kettle; 7. the subglobose float plug that last lower shaft is arranged; 8, bottle plug puncture unit; 9, air filter; 10. the center is porose. play the dividing plate of anastomosis;

Fig. 2 is a float plug sketch map.The 7th, the subglobose float plug of last lower shaft is arranged.Fig. 3 is that the center is porose. the profile of the dividing plate 10 of interconnect function has been arranged..Fig. 4 is that the center is porose. the dividing plate vertical view of interconnect function has been arranged.

The specific embodiment

The said a kind of disposable transfusion device with the float plug of this utility model is selected polyethylene for use, polypropylene, and the material of health licenses such as terylene is used blowing, injection moulding, heat seal process fabrication techniques.

Float plug 7 and the dividing plate 10 that interconnect function is arranged can be used the method making of injection moulding and heat seal, or respectively with float beyond the Great Wall, the bottom with injection mo(u)lding after, heat seal again.To drip kettle and be cut into two joints, and float plug 7 packed into drip the kettle bottom, refill the dividing plate 10 of interconnect function, connect the top of dripping kettle again.During connection, the method for available bonding or heat seal.

Method for using

Take off helmet 2, open medicine speed actuator 5, bottle stopper is worn device insert infusion bottle (bag).And will drip kettle 6 and keep flat, after waiting to be full of medicinal liquid, to place vertically again, float rises beyond the Great Wall, heads on the connection dividing plate, and medicinal liquid flows downward through dripping a kettle 6, passes through medicine speed actuator 5 again, and liquid medicine filter 4 is to intravenous needle output.Close medicine-feeding velocity modulation joint device 5 again, intravenous needle is penetrated human body.Open medicine speed actuator 5, transfer to suitable flow velocity, infuse.When medicinal liquid was totally lost soon, the float plug descended, and blocked to drip kettle 6 outlets, took off transfusion device.The utlity model has blood return prevention, anti-bubble is imported human body and is stopped the function of infusing automatically.

Claims

1. disposable transfusion device with the float plug, the float plug of lower shaft in its kettle, having, dividing plate is characterized in that: drip subglobose float plug that last lower shaft is arranged in the kettle and drip the disposable transfusion device that the porose dividing plate of interconnect function has been arranged in the middle part of the kettle.
