Abstract

This product liquid is to the greatest extent, flow back is used in a kind of corollary apparatus on medical infusion lines from only alarm.Infusion hole is automatically closed after capable of making infusion-completed, prevents patient blood from flowing backwards, and this information is directly fed back into medical matters duty room.Make transfusion patient in the case where being kept an eye on whether there is or not personnel, can safety and steady progress and end.

Description

Liquid is to the greatest extent, flow back certainly only alarm

Affiliated technology technical field：

This product liquid is most, and reflux is used in a kind of corollary apparatus on medical infusion lines from only alarm.

Background technology：

Currently, the transfusion system device in each hospital is manually to ring the doorbell or shout that doctor is notified to change bottle.Such as patient accompanies Shield personnel do not look or fall asleep, and in the case where liquid is all totally lost again, blood in patient body will be flow backwards into woven hose. And the woven hose of air bag hypomere is difficult once to drain into gas.Staff often needs pipe crimping several times and uses hand repeatedly Refer to the bubble of hypomere springing into air bag slowly, infusion can be just normally carried out, bothersome and annoying.

Invention content：

A kind of liquid is most, flow back is connected on woven hose the nozzle lower portion after feed liquor syringe needle from only alarm, and liquid is most, flows back The nozzle in air bag epimere is connected to from the outlet tube mouth of only alarm；Technical solution is used by solving its technical problem：It will Liquid is to the greatest extent, only the component concentrated setting of alarm only has in a thickness in several millimeters of flat roundlet box certainly for reflux；In flat roundlet Longitudinal sealing has a small baffle in box, liquid is use up, flow back is divided into fluid collection chamber and without sap cavity from only alarm；In the product of roundlet box Holes is equipped with below sap cavity on plate.One hole is spray hole；The lower nozzle of spray hole is sealed with a connecting tube, connecting tube it is another One passes through lower panel from the reverse side of lower panel, sealing is connected to the funnel hole of top panel reverse side by fluid collection chamber, funnel hole connects The feed liquor nozzle on logical top；Spray hole lower part is fluid hole, and fluid hole is connected to the outlet tube mouth of lower part；Hydrojet on plate below It is a non-return flowing plate on hole and the face of fluid hole；The other end of non-return flowing plate is fixed with an axis, and the both ends activity connected set of axis exists On axis frame, axis frame is fixed on set below on plate；Axis in non-return flowing plate enters aneroid from fluid collection chamber across partition board Intracavitary, and be fixedly connected with the plastic end on dynamic metal contact piece；It is every empty hard contact under the top of dynamic metal contact piece； Dynamic metal contact piece and hard contact have a contact conductive connecting line and contact conductive line to be fixedly connected on the electricity for leading to outside respectively On supply socket metal wiring terminal；When infusion, as long as staff squeezes air bag, the air on nozzle top is drained, liquid is just It can be sprayed, non-return flowing plate jacked up, then exit into onto air bag from fluid hole and outlet tube mouth from spray hole by connecting tube Woven hose.To initially enter infusion program；After infusion-completed, spray hole stops hydrojet, and non-return flowing plate is fallen, and is covered Fluid hole and spray hole, but at this time still retain some liquid between plate and non-return flowing plate below and can not drain；Therefore Original liquid will all be accumulated in the woven hose of the upper-lower section of air bag and suspend flowing；With falling for non-return flowing plate, only Axis on back flow plate also and then rotates, and the dynamic metal contact piece on the other end of axis is also and then fallen, and is contacted with hard contact, power supply It connects, information is directly delivered to medical matters duty room.In next step, medical worker need to only change bottle.

The advantageous effect of this product is that infusion can be made in the case where being kept an eye on whether there is or not personnel, can safety and steady completion it is defeated Liquid, and can information be directly fed back to medical matters duty room automatically.Save that medical worker spends because excluding gas simultaneously when Between, the spending needed for a large amount of bed switch and other equipment is also saved, and simple in structure at low cost.

Description of the drawings：

Fig. 1 is most for liquid, elevation cross-sectional view of the reflux from only alarm.

Fig. 2 is most for liquid, cross section vertical view of the reflux from only alarm.

(1) non-return flowing plate in figure；(2) spray hole；(3) fluid hole；(4) connecting tube；(5) funnel hole；(6) partition board；(7) golden Belong to contact；(8) metal contact piece is moved；(9) contact conductive connecting line；(10) contact conductive line；(11) axis；(12) axis frame；(13) Without sap cavity；(14) fluid collection chamber；(15) power outlet；(16) lower panel；(17) top panel；(18) feed liquor nozzle；(19) outlet tube Mouthful.

Specific implementation mode：

It is the elevation cross-sectional view that liquid is most, reflux stops alarm certainly in the embodiment in figure 1.

(1) non-return flowing plate other end has fixed (11) axis, (11) axis activity to be attached in figure in Fig. 2 embodiments (12) on axis frame, the fixation of (12) axis frame is set on (16) lower panel.(11) the axis other end passes through (6) from (14) fluid collection chamber Partition board, the plastic end for moving metal contact piece without sap cavity and (8) into (13) are fixedly connected, in the case where (8) move metal contact piece top every Sky is equipped with and is fixed on (7) hard contact on (16) lower panel, and (7) hard contact has (10) contact conductive line and (8) dynamic (9) contact conductive connecting line on metal contact piece all lead in outer (15) power outlet respectively by fixed be connected on.In (1) non-return flowing plate It is (2) spray hole of (3) fluid hole and upper bit on (16) lower panel below center, (3) fluid hole passes through (16) lower panel, And it is connected to (19) outlet tube mouth, (19) outlet tube mouth seals the nozzle of communicated air bags epimere.(2) spray hole seals (4) connecting tube And (16) lower panel is passed through, then from the reverse side of (16) lower panel (14) fluid collection chamber is crossed across (16) lower panel from bottom to top, then with (17) (5) funnel hole of top panel is tightly connected.(5) funnel hole leads to (18) feed liquor nozzle, and (18) feed liquor ferrule leads to Nozzle after feed liquor syringe needle.
