Abstract

The utility model relates to a disposable auto air exhaustion separation equipped transfusion system, comprising a plastic injecting bottle needle, an air filter, a Transfusion system pipe, a separation equipped bag, a Murphy's pipe, a governor, a terminal filter and a scalp needle, wherein the transfusion system is added with a connection separator and an air exhaustion pipe and an air inlet, the separator is cascaded on the lower end between the Murphy's and the terminal filter, one end of the air exhaustion pipe is connected with the separator, and the other end is communicated with the air inlet on the upper end of he separation equipped bag, which can prevent the happening of the air blocking and avoid the medical liquid waste brought by the air exhaustion.

Description

Disposable automatic-exhaust infusion set

Technical field

It specifically is transfusion device that this utility model relates to a kind of medical apparatus and instruments

Background technology

Existing automatic-exhaust transfusion device has solved general infusion set can not self-bleeding problem.But progress along with society, actual needs, the packing transfusion device is in wide clinical application, obtain medical worker's generally approval, it saves liquid than general infusion set, has the labour-saving advantage, but the air that enters in this kind liquid-transport pipe-line still can only descend along pipe, must still there be the possibility of liquid waste and liquid medicine contamination in air by the staff in the discharging of the pin place of connecing; If discovery is untimely or deal with the possibility that still exists air embolism to take place improperly.

The utility model content

This utility model purpose provides a kind of air that can get rid of automatically in the packing transfusion organ pipe, prevents the automatic-exhaust infusion set of air admission human body.

This utility model in order to achieve the above object, a separator and an exhaustor and an air inlet on existing packing transfusion device, have been added, exhaustor one end is connected with separator, the other end joins with branch pack air inlet and communicates, and separator is serially connected between the liquid-transport pipe-line of Murphy type tube lower end and inline final filter.

This utility model since adopted above structure, its advantage be can will enter air in the packing transfusion organ pipe all discharge automatically, prevented the air admission blood vessel, avoided that air embolism takes place may be with former bleeding the time liquid waste and liquid medicine contamination.Owing to do not need air is guarded and handled in infusion process, operating procedure is more easier than existing transfusion device, has strengthened the safety of transfusion patient effectively and has alleviated medical worker's workload.

Description of drawings

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

Fig. 1 is an annexation sketch map of the present utility model.

Among the figure: 1, plastics needle for inserting bottle, 2, air filter, 3, liquid-transport pipe-line, 4, divide pack, 5, Murphy type burette, 6, separator, 7, exhaustor, 8, speed regulator, 9, inline final filter, 10, scalp acupuncture, 11, air inlet, 12, dosing mouth.

The specific embodiment

As shown in Figure 1, this utility model is made up of plastics needle for inserting bottle 1, air filter 2, liquid-transport pipe-line 3, branch pack 4, Murphy type burette 5, separator 6, exhaustor 7, speed regulator 8, inline final filter 9, scalp acupuncture 10, air inlet 11, dosing mouth 12.Plastics needle for inserting bottle 1 one ends connect air filter 2, the other end connects liquid-transport pipe-line 3, liquid-transport pipe-line 3 connects and divides pack 4, divide pack 4 lower end liquid-transport pipe-lines 3 serial connection Murphy type tubes 5, Murphy type tube 5 lower ends connect an end of separator 6 with liquid-transport pipe-line 3, connect exhaustor 7 again at this end, the other end of exhaustor 7 connects the air inlet 11 that divides pack 4, the other end of separator 6 connects inline final filter 9 with liquid-transport pipe-line 3, inline final filter 9 union joint sword-shaped needles 10, speed regulator 8 is enclosed within on the liquid-transport pipe-line 3 that connects between separator 6 and the inline final filter 9, and each parts is all selected the disposable use of medical macromolecular materials for use except that scalp acupuncture 10.

This automatic-exhaust infusion set differs according to water and air specific weight, the pressure reduction of tube for transfusion and exhaustor and law of connected vessels design.When the pipeline of air admission Murphy type tube lower end arrived separator, the exhaustor that air is communicated by separator was discharged and is entered branch pack air inlet, thereby has finished self-bleeding process.

Claims

1, disposable automatic-exhaust infusion set comprises plastics needle for inserting bottle, air filter, liquid-transport pipe-line, branch pack, Murphy type tube, speed regulator, inline final filter, scalp acupuncture, it is characterized in that: on this transfusion device, increase connection separator and exhaustor and air inlet, separator is serially connected between Murphy type tube lower end and the inline final filter, one end of exhaustor links to each other with separator, and the other end links to each other with a minute pack upper end air inlet and communicates.
