Abstract

The utility model provides an exhaust tube for an infusion bottle. The exhaust tube comprises an exhaust tube and a syringe needle arranged at the front end of the exhaust tube; a filter device is arranged at the rear end of the exhaust tube; a closed cavity is formed between the exhaust tube and the filter device; the cavity is communicated with the external environment through an air valve. According to the exhaust tube provided by the utility model, the tightness is good; the syringe needle and a bottle plug are sealed through a taper-shaped sleeve, so that, the tightness is good, no liquid medicine is leaked at the syringe needle; the outside air enters the exhaust tube through the filter device, so that the intake air is clean; the surface temperature of the exhaust tube is reduced, and the exhaust tube is suitable for the liquid medicine which is not suitable for high temperature.

Description

The exhaustor that a kind of infusion bottle is used

Technical field

This utility model relates to a kind of armarium, is a kind of transfusion exhaust apparatus, the exhaustor that particularly a kind of infusion bottle is used.

Background technology

Infusion bottle article deduction needs to insert exhaustor during transfusion, in order in infusion bottle, to import air, equilibrium air pressure.Existing exhaustor front end is a medicated pillow, and rear end opening utilizes medicated pillow to insert the infusion bottle bottle stopper, and the problem of existence is between syringe needle and the bottle stopper slit to be arranged, and transfusion time has been grown and occurred medicinal liquid seepage phenomenon easily, is a kind of wastes for some valuable medicinal liquids; Exhaustor directly contacts with outside air, and summer temperature is higher, and the medicinal liquid that has is difficult under the high situation of temperature, importing, and easily airborne antibacterial is imported in the infusion bottle, and harm transfusion personnel's is healthy.

The utility model content

The purpose of this utility model is to provide.

For achieving the above object; This utility model is realized through following technical scheme: the exhaustor that a kind of infusion bottle is used, and the exhaustor that a kind of infusion bottle is used comprises exhaustor and the syringe needle that places the exhaustor front end; On this syringe needle taper sheath is set; This exhaustor rear end is provided with defecator, forms an airtight chamber between exhaustor and the defecator, and this chamber is communicated with external environment condition through air valve.

Further, said defecator packet filtering film and airtight chamber.

The beneficial effect of this utility model:

1, good airproof performance, syringe needle and bottle stopper quality inspection are through the taper sheath sealing, and good airproof performance syringe needle place medicinal liquid seepage can not occur and have now.

2, air inlet health, outside air gets into exhaustor through defecator.

3, reduced the surface temperature of exhaustor, which can be fit to should not use by the high medicinal liquid of temperature.

Description of drawings

According to accompanying drawing and embodiment this utility model is done further explain below.

Fig. 1 is the structure chart of this utility model.

Wherein, 1-exhaustor, 2-syringe needle, 3-taper sheath, 4-defecator, 5-filter membrane, 6-airtight chamber, 7-air valve.

The specific embodiment

For the purpose, technical scheme and the advantage that make this utility model is clearer, will combine accompanying drawing that this utility model embodiment is done to describe in detail further below.

As shown in Figure 1; The exhaustor 1 that a kind of infusion bottle is used; Comprise exhaustor 1 and the syringe needle 2 that places the exhaustor front end, taper sheath 3 is set on this syringe needle, this exhaustor rear end is provided with defecator 4; Form an airtight chamber 6 between exhaustor 1 and the defecator 4, this chamber is communicated with external environment condition through air valve 7.Defecator 4 comprises filter membrane 5 and airtight chamber 6.

Above-mentioned preferred embodiment and the institute's application technology principle that is merely this utility model; Any technical staff who is familiar with the present technique field is in the technical scope that this utility model discloses; The variation that can expect easily or replacement, all should be encompassed in this utility model protection domain in.
