Description
Technical field
The present invention relates to the field of medical instrument technology, can prevent the fixed of random adjustable pulley more particularly to one kind
Infusion apparatus switch.
Background technique
Infusion apparatus or infusion pump are as its name suggests a kind of medical instruments of infusion.Traditional infusion method is handle
In bottle or infusion bag interrupts liquid suspension aloft, so that liquid is flowed into vein by infusion rubber tubing using the effect of gravity
Interior, the size of flow is carried out manual adjustment by the clip being placed on leather hose, and the index of adjusting is the drop speed seen in dropper.
The switch of existing perfusion tube is slided on frame by pulley, and to adjust transfusion speed, however existing infusion apparatus is opened
Close structure it is simple, after medical worker regulates number of infusion drops, pulley can not be fixed, cause many patients, family members or accompany and attend to for
Liquid is as early as possible finished and arbitrarily rolling pulley adjusts transfusion speed, is required or best therapeutic effect so that treatment be not achieved,
Possibly even cause complication of being infused, such as pulmonary edema, practicability and safety be all to be improved.
Therefore above-mentioned technical problem how is solved, there is very much realistic meaning to those skilled in the art.
Summary of the invention
It is an object of the invention to: it is simple in order to solve existing infusion apparatus construction of switch, many patients, family members or accompany and attend to for
Liquid is as early as possible finished and arbitrarily rolling pulley adjusts transfusion speed, is required or best therapeutic effect so that treatment be not achieved,
The technical issues of possibly even causing infusion complication, the present invention provide a kind of fixed infusion device that can prevent random adjustable pulley
Switch.
The present invention specifically uses following technical scheme to achieve the goals above:
A kind of fixed infusion device switch for preventing random adjustable pulley, including frame are provided with and can be rolled up and down in frame
The dynamic pulley for being used to adjust transfusion speed, frame two sidewalls offer several through-holes in correspondence with each other, the setting of frame side
There are two pieces of slide plates, setting adjusts one of cylinder far from frame there are two can slide up and down to adjust cylinder between two slide plates
End offers jack, adjusts and is provided with clamp button of the spring mechanism in cylinder, and clamp button of the spring mechanism is respectively connected with stretching and adjusts circle
Cylinder and the inserted link that may pass through corresponding through-hole.
Further, clamp button of the spring mechanism includes the first helical teeth column in close jack direction and mutually matches with the first helical teeth column
The the second helical teeth column closed, the second helical teeth column are connect with inserted link, offer guide groove along its length direction on the first helical teeth column, are adjusted
Section cylinder inner wall is provided with the gib block with guide groove cooperation, and several cards with gib block cooperation are offered on the second helical teeth column
Slot, second helical teeth column one end are connected with the guide sleeve being set on inserted link, are arranged on inserted link positioned at guide sleeve and are adjusted on the inside of cylinder
Compressed spring between end.
Further, vertical slide guide track is provided on the inside of two slide plates, adjust on cylinder setting there are two with it is right
The slide guide component for answering slide guide track to cooperate.
Further, frame and slide plate are transparent plastic material.
Beneficial effects of the present invention are as follows:
1, after medical staff regulates transfusion speed by pulley, then by one of cylinder that adjusts along slide plate
Pulley lower position is slid into, is injected and is adjusted in cylinder from jack with a thinner mandril, push the spring snap device, until
Inserted link injects in corresponding through-hole, this inserted link is located at pulley bottom and then takes out mandril to limit pulley slide downward, in bullet
Spring snap device effect lower plunger remain stationary, similarly, by another adjusting cylinder slide into pulley top position, by mandril from
Jack injects this and adjusts in cylinder, and push the spring snap device corresponds in through-hole until inserted link injects, this inserted link is located at pulley top
Portion then takes out mandril to limit pulley upward sliding, that is, completes the fixation to pulley, and clamp button of the spring mechanism is being adjusted
Cylinder interior needs dedicated tiny mandril that could change the locking of clamp button of the spring mechanism and opening state, patient or family members then without
Method rolling pulley easily effectively solves the drawbacks of infusion pulley can be slided arbitrarily, and number of infusion drops is controlled in medical staff completely
In hand, in medical treatment and nursing, to guarantee medical safety, infusion complication is reduced, allows treatment to reach better effect, needs again
When secondary adjusting number of infusion drops, mandril being inserted into and is adjusted in cylinder, push the spring snap device comes inserted link from through-hole pop-up, thus
The limitation to pulley is released, it is easy to operate.
2, clamp button of the spring mechanism is identical with automatic ball-pen internal structure principle, when pushing the first helical teeth column with mandril
When, guide the first helical teeth column to move along a straight line under gib block effect, the helical teeth of the first helical teeth column and the second helical teeth column intermeshes,
The second helical teeth column can be moved forward and be turned an angle under helical teeth effect, while inserted link is also ejected and passes through on frame
Through-hole, at this time the second helical teeth column compressed spring effect under can be directed to an end block it is motionless, then extract out mandril, need
When inserted link is resetted, mandril is pushed into the first helical teeth column, the second helical teeth column is moved forward and turned an angle, until guiding
Item sticks into card slot, extracts mandril out, the second helical teeth column as the first helical teeth column moves back under compressed spring effect, also extract out by inserted link
Through-hole, it is easy to operate, dexterously ball point pen principle is used on infusion apparatus switch, it is novel in design.
3, frame and slide plate are transparent plastic material, when inserted link is directed at corresponding through-hole, convenient for directly observing.
