Description

A kind of adjustable flow control transfusion catheter folder

Technical field

The utility model relates to the field of medical instrument technology, specially a kind of adjustable flow control transfusion catheter folder.

Background technique

The speed of clinical patient infusion will determine according to drug and patient profiles, cancer patient, diabetic, old Compared with weak person in infusion, the speed and dosage of infusion need accurate control for people, children and constitution, are infused too fast, may lead Poisoning is caused, will lead to oedema and heart failure when more serious；Being infused, it is inadequate then to occur dose slowly, make to treat it is impacted simultaneously Increase unnecessary burden to patient and nursery work.It is defeated generally to hang bottle using disposable infusion set for routine clinical infusion Liquid is observed with eyes, controls the speed of medicine drop by flow regulator is adjusted.The micro infusion more demanding to infusion accuracy For, this mode cannot reach requirement.Internal medicine, surgery, paediatrics, cardiology department, emergency department and the operating room of hospital, especially The infusion in the ward ICU and CCU must be accurately infused in many cases.

Existing transfusion catheter folder exists following insufficient: 1, the transfusion catheter folder sold currently on the market is difficult accurately to adjust The speed for saving infusion, is not able to satisfy the requirement of patient and hospital to infusion flow；2, since transfusion catheter folder is the every angel of hospital With the more instrument of number, so being also very necessary to the protection of instrument.

Utility model content

The purpose of this utility model is to provide a kind of adjustable flow control transfusion catheters to press from both sides, to solve in above-mentioned background technique The problem of proposition.

To achieve the above object, the utility model provides the following technical solutions: a kind of adjustable flow control transfusion catheter folder, packet Crushing block and bear block are included, the crushing block middle position is provided with extruding plate, and the bear block middle position is provided with and squeezes The receiving piece that tabletting matches, described crushing block one end offer the first convex block, and it is convex to offer second in front of first convex block Block, described bear block one end offer the first groove and the second groove with the first convex block and the matching of the second convex block, the extruding Block is provided with pressing arm far from one end of the first convex block, and the pressing arm is provided with U-shaped buffer wall, institute far from one end of crushing block It states U-shaped buffer wall and one end of pressing arm is provided with latch portion, the lock lower surface is provided with several upper locking teeths, institute It states bear block and is fixedly installed with receiving arm far from one end of the first groove, the upper surface for bearing arm is provided with and upper locking teeth The lower locking teeth to match.

Preferably, the one end of crushing block and bear block far from pressing arm is connected by linking arm.

Preferably, the height of the extruding plate and receiving piece is higher than crushing block and bear block.

Preferably, the crushing block, extruding plate, bear block and receiving piece are semicircle.

Preferably, the U-shaped buffering wall surface offers cushion hole.

Compared with prior art, the utility model has the beneficial effects that

1, the utility model is by the utility model by being arranged pressing arm in crushing block one end, and pressing arm is far from crushing block One end be provided with U-shaped buffer wall, one end of U-shaped buffer wall is provided with latch portion, and lock lower surface offers several lockings Fixed tooth offers on bearing wall with what upper locking teeth matched and divides into fixed tooth, by the flexible U-shaped buffer wall of movement come It adjusts latch portion and bears at a distance from arm, when upper locking teeth is locked together with lower locking teeth, can pass through and adjust the two lock Fixed distance controls crushing block bear block to the extruding force of perfusion tube, and the flowing velocity of medical fluid in perfusion tube is controlled with this, Be conducive to meet hospital and patient the needs of transfusion speed, is made it is not only more efficient but also more humane at work, by The first convex block and the second convex block are opened up on crushing block, and matched the first groove and the second groove are opened up in bear block, Such as often has the bottom for needing that upper locking teeth can directly be snapped into lower locking teeth the case where stopping infusion during infusion Portion, at this moment the first convex block, the second convex block and the first groove, the second groove are combined closely so that crushing block and bear block are by perfusion tube Folder is dead.

2, for the utility model by opening up cushion hole in U-shaped buffer wall upper surface, cushion hole is hollow institute by centre Can be stronger with retractility and extruding ability to bear, since the frequency that U-shaped buffer wall uses in use is highest, so It is easiest to damage, it can be played a certain protective role by the way that a cushion hole is arranged.
