Abstract

The utility model discloses a safe airbag capable of protecting infusion against secondary pollution, which comprises a safe airbag and an air duct, wherein the safe airbag can be filled with clean air, and a sealed air nozzle is formed on the safe airbag; and the air duct is matched with the safe airbag. Therefore, the clean air for forming pressure can be directly infused into an infusion bottle through connecting the air duct with the air transmission function and the infusion bottle by utilizing the safe airbag; and in addition, when the air in the safe airbag is used up, the pressure can not be supplied for liquor in the infusion bottle and the infusion is stopped, thereby effectively ensuring the safety of a patient. The safe airbag is suitable for the air required to be supplied for infusion and blood transfusion.

Description

The air bag of secondary pollution can prevent to infuse

Technical field

This utility model belongs to the device that clean air is provided to infusion bottle in the medical infusion process, be a kind of air bag of the secondary pollution that prevents to infuse specifically, can effectively avoid air pollution to enter in the human body or the function of automatic stop liquid during control infusion bottle aneroid with medicinal liquid.

Background technology

Usually in the venous transfusion process, tube for transfusion and air inlet pipe need be inserted on the bottleneck of infusion bottle, be input in the patient's vein by the medicinal liquid of tube for transfusion infusion bottle (or transfusion bag), and air inlet pipe is that air outside is sent in the infusion bottle, in order to increase the pressure in the bottle, guarantee the fluency of transfusion.But, because of containing a large amount of harmful material that is invisible to the naked eye in the air outside.On the one hand, contact with medicinal liquid in the bottle, cause medicinal liquid pollution in various degree as having the viral bacterium to cause disease in a large number, dust, big or small prescription Organic substance, deleterious inorganic matter etc. in the air of dirt, all entering into by air inlet pipe.The medicinal liquid that will be mixed with harmful substance like this is input in the patient's vein, the factor of the potential health that exerts an influence of meeting; On the other hand, when after transfusion is finished, not had medicinal liquid in the bottle, as can not get timely processing, also can enter in the vein of human body through tube for transfusion by the air that air inlet pipe imports in the bottle, the malpractice of air embolism will take place, so not only bring misery, also can involve medical personnel's question of liability simultaneously to the patient.Therefore, the attached air inlet pipe that helps of the existing employing mode that improves infusion pressure must be improved and be perfect.

Summary of the invention

In view of the present situation of above-mentioned technology, the purpose of this utility model provides a kind of air bag of the secondary pollution that prevents to infuse, and it has can avoid sneaking into of extraneous air, takes into account when reaching in the infusion bottle no medicinal liquid to stop transfusion automatically, guarantees the purpose of patient safety.

For achieving the above object, technical solution of the present utility model is by finishing to get off.A kind of air bag of the secondary pollution that prevents to infuse comprises an air bag with the clean air of packing into, and the valve of a sealing is arranged on this air bag; And have one with the supporting airway of air bag.Therefore, utilize air bag to be connected with infusion bottle, directly the clean air of input formation pressure in infusion bottle by airway with gas transmission effect; In addition, after the air bag air is used up, can't pressure be provided and stop transfusion by the medicinal liquid in infusion bottle, effectively guaranteed patient's safety.

According to application characteristic of the present utility model, a unidirectional control valve is set on the related air bag.Air capacity in the scalable air bag equates that with amount of liquid medicine in the infusion bottle maintenance is exported synchronously like this.

According to scheme of the present utility model, related airway, it has at the two ends of described airway syringe needle is set.Can utilize two syringe needles to insert the delivery outlet of air bag and infusion bottle respectively like this, realize the purpose of output clean air, avoid entering of outside air, guarantee safety.

According to scheme of the present utility model, described air bag is a separate component, or makes the complex with two cavitys of same whole separation with transfusion bag.This air bag is as separate component and infusion bottle fit applications, and air bag can be reused simultaneously; If air bag and transfusion bag as complex can reduce the operation link in the application, convenient again disposable use.

In a word, the air bag of the secondary pollution that prevents to infuse of the present utility model can fill in the air bag clean air and sealing by manufacturer.Therefore, when airbag safe in utilization cooperated infusion bottle or transfusion bag, the air that can eliminate medicinal liquid and external contamination was isolated, and clean air directly is provided, and helps patient's safety; In addition, the minimizing that can utilize aeration quantity in the air bag during use is greater than the minimizing of amount of liquid medicine or keep synchronously, can stop automatically infusing in the time of can controlling in the infusion bottle of infusion process or the transfusion band no medicinal liquid like this, avoids the patient that the probability of air embolism takes place.This air bag is applicable to the air that transfusion, blood transfusion need provide.

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

Fig. 2 is another embodiment sketch map of Fig. 1;

Fig. 3 is another example structure sketch map of Fig. 1, Fig. 2.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

Embodiment 1

By the infuse air bag of secondary pollution of shown in Figure 1 preventing, comprise an air bag 1 that has hanger 2.Seal in having a valve 3 on the air bag 1 and the plug 4 that is used to seal being installed on it outward.Then air bag 1 is matching used with it is an airway 5, and the two ends of this airway 5 respectively have a syringe needle 6.During use, with airway 5 wherein the syringe needle 6 of an end insert air bag 1 sealing-plug 4 with it cavity communicate; And the syringe needle 6 of conduit 5 other ends inserts infusion bottle.Like this, the clean air in the air bag 1 enters by airway 5 and produces pressure reduction in the infusion bottle, and medicinal liquid is transported in the vein of human body through tube for transfusion.

According to These characteristics, air bag 1 of the present utility model also can be used with transfusion bag except that being used with infusion bottle.

In the present embodiment, related airway 5 can utilize existing air inlet pipe with wherein plug of end installation and syringe needle get final product two ends except the special product of selecting manufacturer for use.

Embodiment 2

See that accompanying drawing 2 has provided another embodiment of Fig. 1, what it was different with Fig. 1 is to have a unidirectional control valve 7 is set on air bag 1.The effect of this unidirectional control valve 7 is to regulate gas-storing capacity in the air bag 1, the gas-storing capacity and the medicinal liquid in the infusion bottle that help regulating air bag 1 keep certain ratio, can stop automatically infusing during no medicinal liquid in infusion bottle that can the security control infusion process or the transfusion band.

In the present embodiment, mentioned unidirectional control valve 7 is to select existing medical unidirectional control valve product for use.
