Description

A kind of automatic exhaust device and use its transfusion device
Technical field
The present invention relates to technical field of medical instruments, a kind of automatic exhaust device for transfusion device and Use the transfusion device of this automatic exhaust device.
Background technology
Now the transfusion device of Clinical practice mainly have bottle plug puncture unit, air filter, dropping funnel, flexible pipe, flow regulator, Liquid medicine filter and venoclysis needle composition.Before to patient fluid infusion, bubble in transfusion device must be completely exhausted out by medical personnel. Common practice is, is inserted by bottle plug puncture unit in infusion bottle, is inverted dropping funnel, after making liquid be filled with dropping funnel half, dropping funnel is suitable Put, or flow regulator cut out, extrude dropping funnel, after liquid enters about dropping funnel half, slowly open flow regulator, Then wait that the soft air in tube of dropping funnel bottom is completely exhausted out, and is again switched off flow regulator.This process operation is complicated, the time Long, affect work efficiency.If misoperation, it is difficult to ensure that liquid level in dropping funnel, it is unfavorable for that medical personnel observe transfusion and drip Number, and in dropping funnel, liquid and gas are mixed into flexible pipe, can form bubble, cause potential safety hazard.
Having automatic-exhaust transfusion device in the market, its design has:
One, placing exhaustor bottom dropping funnel, the liquid outlet of dropping funnel upper end and exhaustor are on the same axis (such as: real With automatic-exhaust transfusion device disclosed in new patent ZL200820166716.9);
Two, two exhaustors are symmetrically distributed on the aerofluxus base bottom dropping funnel, and the liquid outlet of dropping funnel upper end is not same On axis (such as: automatic venting device of transfusion device disclosed in patent of invention ZL200910093070.5);
Three, placing exhaustor bottom dropping funnel, block covers exhaustor (such as: utility model patent Disclosed in ZL201120015920.2, a kind of infusion set is with exempting from aerofluxus dropping funnel).
Three of the above design, medicinal liquid can directly instill in exhaustor in actual use, forms gas-liquid mixed Body enters in flexible pipe, causes aerofluxus failure, or after infusion process is interrupted or changed dressings, if the emptying of dropping funnel inner liquid medicine, continues Using, in dropping funnel, liquid level there will be phenomenon that is too low or that do not keep liquid level, liquid now will be had to be mingled with bubble and enter In the flexible pipe of dropping funnel bottom, therefore also need to medical personnel's aerofluxus again, so increase the working strength of medical personnel, also wave Take treatment time.
Summary of the invention
The present invention be directed to the deficiency of above-mentioned automatic-exhaust transfusion device, it is provided that a kind of automatic exhaust device and use the defeated of its Liquid device.
On the one hand, the present invention provides a kind of automatic exhaust device, in the dropping funnel of transfusion device, including:
Air bleeding valve base, is fixedly mounted in dropping funnel, and the inner wall sealing of described air bleeding valve base and described dropping funnel is even Connecing, described air bleeding valve base is provided with the aerofluxus post turning on described air bleeding valve base upper space with the outlet of described dropping funnel, The sidewall of described aerofluxus post is provided with at least one first row air drain extended along vertical direction;

It is further preferred that the width of described second row air drain is at least 1mm, it is further preferred that described second row The width of air drain is 1.7mm;
Described first row air drain is opened in described the radially staggered of aerofluxus post with described second row air drain, and described first row Air drain has overlapping with described second row air drain at the axial direction of described aerofluxus post.
Selectively, the bottom of described air bleeding valve helmet is provided with outward extending auxiliary section, described auxiliary section and described row Air valve base is tightly connected.
Preferably, the mode of ultrasonic bonding is used to be connected between described air bleeding valve helmet with described air bleeding valve base.
It is further preferred that described air bleeding valve base is provided with limit rib, described limit rib is along the footpath of described aerofluxus post To setting;The bottom of described air bleeding valve helmet is provided with the locating notch coordinated with described limit rib, and described locating notch is with described Limit rib is tightly connected.
Preferably, described locating notch turns on described second row air drain.
Preferably, the top of described aerofluxus post is blind hole or through hole, and the bottom of described aerofluxus post is through hole.
It is further preferred that the bottom through-hole of described aerofluxus post is corresponding with the outlet of described dropping funnel.
Preferably, described first row air drain is equal with described second row air drain quantity.
Preferably, described aerofluxus post, described air bleeding valve helmet are rotary structure, and described first row air drain be set to Few three, described first row air drain is uniformly distributed around the circumferencial direction of described aerofluxus post, and described second row air drain is around described The circumferencial direction of air bleeding valve helmet is uniformly distributed.
Preferably, the inwall of described dropping funnel is provided with circular fin, and described air bleeding valve base is fixed on described ring-type convex The bottom of rib.
On the other hand, the present invention also provides for a kind of transfusion device, and it includes above-described automatic exhaust device.
