Description
Technical field
The present invention relates to field of medical device, more particularly to a kind of device adjusted for single bottle monitoring infusion.
Background technology
Venous transfusion is commonly called as having an intravenous drip, and is that one kind utilizes atmospheric pressure and fluid pressure principle by a large amount of sterile liquids, electrolysis
Matter and medicine are inputted the treatment method of human body by vein.Apparatus used in venous transfusion has：Infusion bottle/infusion bag, include drop
Syringe needle is pierced into the vein blood vessel of sufferer by medical personnel and consolidated by infusion tube, infusion regulator and the syringe needle of kettle, transfusion operation
It is fixed, then infusion bottle/infusion bag height is hung and infused, one time infusion process lasts about greatly dozens of minutes.Current, vein is defeated
The transfusion speed of liquid typically carries out manual adjustment by infusion regulator, is then specifically that medical personnel drip liquid in kettle by visual observation
Drop drop speed simultaneously operates the extruding infusion tube of infusion regulator in various degree to realize transfusion speed control.Suitable transfusion speed
So that infusion treatment is more safe and comfortable, therefore judge that transfusion speed is that medical personnel must by dripping the drop speed of the drop in kettle
Standby experience.But this empirical drop speed judges that, with very strong subjectivity, the precision of transfusion speed regulation is not high.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of device for being capable of accurate adjustment transfusion speed.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of single bottle monitoring infusion adjusting means, bag
Include：
The drop kettle groove for accommodating drop kettle and the flexible pipe groove for accommodating infusion tube are provided with housing, housing；
Droplet counter, droplet counter is installed near drop kettle groove, and droplet counter counts the drop in drop kettle and will
Count results are transferred to microprocessor；
Flexible pipe in transfusion speed adjusting gear, the controlled squeezing tube groove of transfusion speed adjusting gear；
Microprocessor, time of the microprocessor according to used in the count results of droplet counter and counting calculates drop kettle
Current to drip speed, the degree of microprocessor control transfusion speed adjusting gear squeezing tube is fast to setting range come the drop for adjusting drop kettle；Tool
Body, if the drop speed of drop kettle is less than the lower limit of setting range, control transfusion speed adjusting gear loosens flexible pipe；If dripping the drop of kettle
Speed is higher than the upper limit of setting range, then control transfusion speed adjusting gear squeezing tube.
Specifically, the transfusion speed adjusting gear includes linear actuator and briquetting, the driving direction of linear actuator is vertical
In the direction of flexible pipe groove, flexible pipe in linear actuator driving briquetting squeezing tube groove or loosen flexible pipe in flexible pipe groove.
Further, the linear actuator includes servomotor, leading screw, guide rail and sliding block；Serve Motor Control leading screw
Rotation, leading screw is threadedly coupled with sliding block, and sliding block is socketed on smooth guide rail, and guide rail is parallel with leading screw；Leading screw, sliding block and guide rail
Structure is by the linear reciprocating motion for being converted into sliding block of servomotor, and slider-actuated briquetting is closer or far from flexible pipe.
Further, the briquetting is lever construction, and the resistance point of briquetting is used to extrude infusion tube, the power point of briquetting
With shoe contact, the power arm of briquetting is more than resistance arm；Briquetting herein is a laborsaving lever, and the move distance of resistance point is small
In the move distance (i.e. the move distance of sliding block) of power point.Due to the diameter very little of infusion tube, and use linear actuator
The precision range control of a small range is not easily accomplished, therefore using the straight of laborsaving lever construction scaled down linear actuator
Lineal travel, with the accurate extruding degree controlled to infusion tube.
Specifically, the droplet counter is infrared photoelectric sensor, it is red that the transmitter of infrared photoelectric sensor is sent
Outer light is received by the receiver through drop kettle；When having liquid drippage in drop kettle, infrared light is by liquid droplets intercept, receiver thus production
A raw electric signal is used to count.
Further, single bottle monitoring infusion adjusting means also includes display screen, and display screen is arranged on surface of shell, display screen
The drop speed of drop in the current drop kettle of display.
Further, single bottle monitoring infusion adjusting means also includes siren, when the drop speed of drop in drop kettle is less than minimum
During setting value, microprocessor control siren sends alarm；Generally minimum setting value will be much smaller than the fast scope of normal drop
Lower limit, when drip prompt drop it is low after, the microprocessor speed adjusting gear that controls to infuse first loosens extruding to infusion tube, if transfusion
The drop speed of drop still is below minimum setting value (drop speed now is in most cases in drop kettle after speed adjusting gear loosens completely
Zero), then judge that the decoction in infusion bottle or infusion bag has run out, microprocessor control siren sends prompting.
Beneficial effect：(1) single bottle monitoring infusion adjusting means of the invention is using in droplet counter accurate measurement drop kettle
The drop speed of drop, then by speed adjusting gear feedback regulation of infusing, process automation progress was entirely adjusted, independent of medical personnel's
Subjective experience, degree of regulation is high.(2) briquetting of single bottle monitoring infusion adjusting means of the invention is a kind of laborsaving lever construction,
Lever construction will be converted into resistance point stroke after the rectilinear path scaled down of linear actuator (resistance point directly extrudes defeated
Liquid flexible pipe), with the accurate extruding degree controlled to infusion tube.(3) single bottle monitoring infusion adjusting means of the invention utilizes aobvious
Display screen shows current transfusion speed in real time, facilitates medical personnel and sufferer to grasp transfusion condition at any time.(4) single bottle of the invention
Monitoring infusion adjusting means can send alarm when the decoction in infusion bottle/infusion bag is used up, it is not necessary to manually deliberately monitor
Transfusion process.
