Abstract
This utility model provides the resistance bacterium aerofluxus of a kind of remaining needle many exchange devices, it comprises: body, described body interior forms the first infusion channel, and described body is formed with at least one arm on lateral wall, and described arm inside is formed with the second infusion channel being connected with described the first infusion channel; On described body and/or arm, offer steam vent, described steam vent place is provided with ventilated membrane, described ventilated membrane inside is formed with some steam vents that communicate with each other, and the size of described steam vent is less than the diameter of hydrone, and is greater than the diameter of the gas molecule of diameter maximum in constituent of air.Remaining needle of the present utility model in resistance bacterium, can, by the Bas Discharged in medicinal liquid, avoid air to enter inside of human body with medicinal liquid with the many exchange devices of resistance bacterium aerofluxus, the safety coefficient while having improved transfusion.In addition, remaining needle of the present utility model also can be avoided the loss of medicinal liquid with the many exchange devices of resistance bacterium aerofluxus, has improved the utilization rate of medicinal liquid, has avoided waste.
Description
Technical field
This utility model relates to a kind of field of medical products, relates in particular to a kind of for the many exchange devices of the resistance bacterium aerofluxus of the remaining needle on remaining needle.
Background technology
Venous detaining needle claims again venous cannula pin, and it comprises the conduit/sleeve pipe that can be retained in endovascular softness, and stainless guiding puncture nook closing member.When use, conduit is punctured into together with nook closing member in blood vessel, when after the whole intravasations of conduit, withdraw out nook closing member, thereby only soft catheter retaining is carried out in blood vessel to infusion treatment.
For example, threeway Y type remaining needle is the one of venous detaining needle, and it has two imports, and an outlet can be used for carrying two kinds of medicinal liquids.In infusion process, in medicinal liquid, may contain a certain amount of air, if this air cannot be got rid of, enter after human body, very large to the harm of human body, can cause air embolism.In order to get rid of gas, can on remaining needle, offer steam vent, but so can cause antibacterial to enter in remaining needle, pollute medicinal liquid, and be detrimental to health.
In view of this, be necessary to propose further solution.
Utility model content
The purpose of this utility model is to provide the resistance bacterium aerofluxus of a kind of remaining needle many exchange devices.
For realizing above-mentioned utility model object, the many exchange devices of resistance bacterium aerofluxus for a kind of remaining needle of the present utility model, it comprises: body, described body interior forms the first infusion channel, described body is formed with at least one arm on lateral wall, and described arm inside is formed with the second infusion channel being connected with described the first infusion channel;
On described body and/or arm, offer steam vent, described steam vent place is provided with ventilated membrane, described ventilated membrane inside is formed with some steam vents that communicate with each other, and the size of described steam vent is less than the diameter of hydrone, and is greater than the diameter of the gas molecule of diameter maximum in constituent of air.
As the further improvement of utility model, described remaining needle is two-way with the many exchange devices of resistance bacterium aerofluxus.
As the further improvement of utility model, described remaining needle is threeway with the many exchange devices of resistance bacterium aerofluxus.
As the further improvement of utility model, described ventilated membrane covers described steam vent.
Compared with prior art, the beneficial effects of the utility model are: remaining needle of the present utility model is with hindering the many exchange devices of bacterium aerofluxus in resistance bacterium, can, by the Bas Discharged in medicinal liquid, avoid air to enter inside of human body with medicinal liquid, the safety coefficient while having improved transfusion.In addition, remaining needle of the present utility model also can be avoided the loss of medicinal liquid with the many exchange devices of resistance bacterium aerofluxus, has improved the utilization rate of medicinal liquid, has avoided waste.
Brief description of the drawings
Fig. 1 is the part plan schematic diagram of a detailed description of the invention of the many exchange devices of remaining needle of the present utility model resistance bacterium aerofluxus.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, this utility model is elaborated; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection domain of the present utility model.
As shown in Figure 1, remaining needle of the present utility model comprises with the many exchange devices 100 of resistance bacterium aerofluxus: body 10, and inner first infusion channel 11 that forms of described body 10, this first infusion channel 11 is for delivery of medicinal liquid.
Described body is formed with at least one arm 20 on 10 lateral walls, and described arm 20 inside are formed with the second infusion channel 21 being connected with described the first infusion channel 11.Can carry two kinds of medicinal liquids by arm 20 simultaneously, meet different patients' transfusion requirement.
On described body 10 and/or arm 20, offer steam vent, described steam vent place is provided with ventilated membrane 30, and these ventilated membrane 30 films cover described steam vent.Described ventilated membrane 30 inside are formed with some steam vents that communicate with each other, and the size of described steam vent is less than the diameter of hydrone, and are greater than the diameter of the gas molecule of diameter maximum in constituent of air.So, the air that is gathered in resistance bacterium many exchange devices of aerofluxus inside can be discharged by ventilated membrane 30, and meanwhile, because the size of steam vent is less than the diameter of hydrone, medicinal liquid cannot be discharged by venting plug 30, and then has played the effect of exhausting liquid-blocking.In addition, the antibacterial of ventilated membrane 30 in also can resistance outside air is set and enters into arm inside.
In sum, remaining needle of the present utility model in resistance bacterium, can, by the Bas Discharged in medicinal liquid, avoid air to enter inside of human body with medicinal liquid with the many exchange devices of resistance bacterium aerofluxus, the safety coefficient while having improved transfusion.In addition, remaining needle of the present utility model also can be avoided the loss of medicinal liquid with the many exchange devices of resistance bacterium aerofluxus, has improved the utilization rate of medicinal liquid, has avoided waste.
To those skilled in the art, obviously this utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or basic feature, can realize this utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in this utility model.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this description is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
