Description
Technical field
This utility model relates to a kind of technical field of single use medical treatment consumptive materials, particularly a kind of Novel bubble-prevention infusion device.
Background technology
At present, disposable infusion set is primarily of bottle plug puncture unit, air filter, flexible pipe, dropping funnel, flow regulator and liquid medicine filter and venoclysis needle composition, usual structure is that bottle plug puncture unit root air inlet connects a flexible pipe, an external air filter, usually connect one, the structure band filter screen of a two dropping funnel below perforator, a band dropping funnel, so just makes the structure of transfusion device become increasingly complex, production cost is more and more higher, and cannot ensure infusion safety.
Utility model content
In view of the foregoing, this programme proposes a kind of structure simple and durable, and be convenient to the transfusion device produced, concrete scheme is as follows:
A kind of Novel bubble-prevention infusion device, comprises integral type bottle plug puncture unit, flow regulator, flexible pipe, liquid medicine filter and autoamtic venipuncture appts: described integral type bottle plug puncture unit comprises dropping funnel lid, dropping funnel lid side is connected with dropping funnel body, and opposite side is provided with bottle plug puncture unit; Dropping funnel lid inside is provided with the fluid guidance port communicated with bottle plug puncture unit, is provided with dropper, forms filter chamber between dropper and fluid guidance port below fluid guidance port, and filter chamber inside is provided with only liquid filter membrane.
As preferably, the linkage section of described dropper and dropping funnel lid lower end is connected by ultrasonic bonding, bonding or click on fashion.
As preferably, the inlet chamber being also provided with air inlet in described dropping funnel lid and being connected with air inlet, air inlet bottle plug puncture unit is connected, and the position that dropping funnel cover outer wall is corresponding with inlet chamber is provided with air switch, is provided with air filter film between inlet chamber and air switch.
As preferably, the cross-sectional sizes of described air inlet is 1/1 to two/4th of fluid guidance port cross-sectional sizes.
As preferably, described dropping funnel lid lower end is provided with groove, is connected by groove by bonding form with dropping funnel body.
As preferably, described bottle plug puncture unit is also provided with helmet centring ring, is fixed by helmet centring ring and helmet.
As preferably, be provided with liquid outlet bottom described integral type bottle plug puncture unit, be connected by flexible pipe with liquid medicine filter one end, the medicine liquid controller other end is connected with autoamtic venipuncture appts.
As preferably, described flow controller is arranged on the flexible pipe of liquid outlet one end.
The only liquid filter membrane that this programme adopts is the extremely strong macromolecular material of a kind of hydrophilic, when only liquid filter membrane runs into liquid, moment is moistening, owing to stopping the film hole diameter very little (5um ~ 8um) of liquid filter membrane, the capillarity produced can be very strong, thus a gravitation is upwards produced to the liquid stopped under liquid filter membrane, the fenestra passing through to be full of liquid to allow gas needs great pressure, thus reach only allow liquid pass through filter membrane, and the effect that gas cannot pass through, thus prevent bubble from entering liquid-transport pipe-line, to ensure infusion safety.When liquid level drop to only liquid filter membrane time, only liquid filter membrane is now equivalent to a switch of closing, in dropping funnel body body air formed negative pressure+human vein pressure=infusion pipeline and dropping funnel body in fluid column formed pressure, in dropping funnel body and flexible pipe, remaining liquid can not continue to decline, reach automatic liquid-stopping effect, the syringe needle of vein penetrator also can not because of negative pressure blood back, infusion safety can be ensured further.Be equipped with air switch outside dropping funnel lid, according to circumstances can adjust and keep the pressure balance in liquid-transport pipe-line, air switch and inlet chamber seam are provided with air filter film simultaneously, for the impurity in filtered air and antibacterial, ensure that liquid is not contaminated.Because the environment for use of stopping liquid filter membrane requires higher, if dropping funnel lid side leaks gas, only liquid filter membrane can be caused to lose efficacy, the linkage section of dropper and dropping funnel lid lower end is connected by ultrasonic bonding, bonding or click on fashion, further while fixing only liquid filter membrane, also the better sealing effectiveness played, to ensure the stability of only liquid filter membrane.If air inlet is greater than fluid guidance port, liquid can be caused to spill from air inlet, and therefore the cross-sectional sizes of air inlet is set to 1/1 to two/4th of fluid guidance port cross-sectional sizes, to ensure that air inlet can not leakage.Bottle plug puncture unit is provided with helmet centring ring, effectively secures helmet, prevents from coming off in moving process, ensures the aseptic of perforator head.
In sum, the advantage of this programme is: can realize preventing bubble from entering liquid-transport pipe-line and automatic liquid-stopping function, improve safety and the aseptic of infusion process, total is simple and reliable, and production cost is low.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further described.
Shown in figure 1, be provided with liquid outlet 17 bottom integral type bottle plug puncture unit 1 to be connected with flexible pipe 3, flexible pipe 3 other end connects liquid medicine filter 4, and liquid medicine filter 4 is connected with autoamtic venipuncture appts 41 again simultaneously, and flow regulator 2 is arranged on the position of flexible pipe 3 near integral type bottle plug puncture unit 1.
Shown in figure 2, disposable bottle plug puncture unit 1 is made up of dropping funnel lid 5 and dropping funnel body 6 and the bottle plug puncture unit 7 be arranged on dropping funnel lid 5, helmet 8 is arranged on bottle plug puncture unit 7 via helmet centring ring 9, dropping funnel lid 5 inside is provided with the fluid guidance port 12 be communicated with bottle plug puncture unit 7, conduit 11 is connected with the linkage section 20 of dropping funnel lid 5 by ultrasonic bonding, filter chamber 19 is formed between fluid guidance port 12 and conduit 11, only liquid filter membrane 10 is arranged in filter chamber 19, two ends by bottom dropping funnel lid 7 and conduit 11 fix.
Shown in figure 3, disposable bottle plug puncture unit 1 is also provided with inlet chamber 16, inlet chamber 16 one end is communicated with air inlet 15, air inlet 15 is communicated with bottle plug puncture unit 7 again simultaneously, the position that dropping funnel lid 7 outer wall is corresponding with inlet chamber 16 is provided with air switch 13, is provided with air filter film 14 between inlet chamber 16 and air switch 13.The cross-sectional sizes of air inlet 15 is 1/4th of fluid guidance port 12 cross-sectional sizes.
With reference to figure 4 with shown in Fig. 5, the groove 18 of dropping funnel lid 5 is linked together by bonding form with dropping funnel body 6, constitutes the main part of disposable bottle plug puncture unit 1.
