Abstract
The invention discloses a kind of transfusion device, including woven hose and dropping funnel, filter, in addition to transfusion monitoring device are provided with the woven hose.The transfusion device of the structure, there is the advantages of adjusting drop number, monitoring and regulation transfusion dosage and filtering transfusion impurity.
Description
Technical field
The present invention relates to medical instruments field, and in particular to a kind of transfusion device.
Background technology
Infusion is medical procedure conventional now, applied to every field such as Neonate transfusions, common transfusion at present
Process is generally all manually to guard.But the task of hospital nurse is heavy, generally requires a nurse and keep an eye on several or dozens of
Bed, thus the monitoring difficult to realize to each transfusion patient.Usual patient is in infusion process if necessary to rest, it is also necessary to
Family members accompany and attend to, in case transfusion stops, the too fast or end time of infusing triggers malpractice too long.
A kind of infusion real-time monitoring device is disclosed in the U of Chinese invention patent specification CN 201469780, including is claimed
Sensor, man-machine interface, alarm etc. are retransmitted, the invention can monitor the quality of remaining decoction in infusion bag, and will in decoction
Alarm signal is sent when dripping off, prompts nurse to extract syringe needle or changes infusion bottle.However, the transfusion in the invention monitors dress in real time
Effective reaction can not be made to the transfusion stopping occurred in infusion process, too fast or excessively slow etc. exception of infusing by putting.It is in addition, existing
Transfusion device the drawbacks of can not being filtered to the impurity in transfusion liquid also be present.
The content of the invention
In view of this, it is an object of the invention to provide a kind of transfusion device, drop number, monitoring can be adjusted and adjust defeated by making it have
The advantages of liquor amount and filtering transfusion impurity.
The present invention is solved the above problems by following technological means：A kind of transfusion device, including woven hose and dropping funnel, it is described defeated
Filter, in addition to transfusion monitoring device are provided with liquid pipe.
Further, the filter includes the filter chamber connected with woven hose and the filter membrane being arranged in filter chamber.
Further, the filter membrane is made up of elastomeric material, and the section of filter membrane is corrugated.
Further, the filter chamber is in funnel-form.
Further, the transfusion monitoring device includes microprocessor, power module, alarm and the infrared folder that tests the speed, described
Alarm is connected with the infrared folder that tests the speed by signal wire with microprocessor, and the infrared folder both sides of testing the speed are provided with along length
The chute of direction extension, is provided with sliding block be connected with slide at the chute, the slider top be provided with rack with
Wedge, it is provided between two racks and passes through rotating shaft and the infrared folder that tests the speed with two equal meshed gears of rack, the gear
The miner diameter end of another wedge of the bigger diameter end face of connection, two wedge faces arrangement and wedge, includes drive
The motor of dynamic axis of rotation, the motor are connected also by signal wire with microprocessor.
Further, the power module includes rechargeable battery and power switch.
Beneficial effects of the present invention：The transfusion device of the present invention, including woven hose and dropping funnel, it was provided with the woven hose
Filter, in addition to transfusion monitoring device.The transfusion device of the structure, have can adjust drop number, monitoring and adjust infuse dosage and
The advantages of filtering transfusion impurity.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of filter；
Fig. 3 is the structural representation of transfusion monitoring device.
Embodiment
Below with reference to accompanying drawing, the present invention is described in detail, as Figure 1-3：A kind of transfusion device, including woven hose 1
With dropping funnel 2, filter 3, in addition to transfusion monitoring device 4 are provided with the woven hose.Specifically, the filter include with
The filter chamber 301 and the filter membrane 302 that is arranged in filter chamber of woven hose connection, the filter chamber are in funnel-form, the mistake
Filter membrane is made up of elastomeric material, and the section of filter membrane is corrugated, and the transfusion monitoring device includes microprocessor 401, power supply
Module 402, alarm 403 and the infrared folder 404 that tests the speed, the alarm is with the infrared folder that tests the speed by signal wire 405 and Wei Chu
Manage device connection, it is described it is infrared test the speed folder both sides be provided with the chute 406 extended along its length, be provided with the chute with
The sliding block 407 of slide connection, the slider top are provided with rack 408 and wedge 409, are provided between two racks
With the equal meshed gears 410 of two racks, the gear is by rotating shaft 411 and infrared folder connection of testing the speed, and gear jacket is in rotating shaft
And be fixedly connected with rotating shaft, rotating shaft and infrared folder rotation connection of testing the speed, two wedge faces arrangement and wedge it is big
The miner diameter end to another wedge, in addition to the motor 412 that drive shaft rotates are rectified in footpath, and the motor is also by signal wire
It is connected with microprocessor, motor is positive and negative motor, and the power module includes rechargeable battery 413 and power switch 414, passed through
Rechargeable battery gives each power elements, ensures the normal use of each element.
During transfusion, dropping funnel can adjust drop number；Filter membrane can be used for the impurity in filtered fluid, and filter membrane is by elastic material
Material is made and section is corrugated, when drop passes through filter membrane, can trigger the elasticity shake that filter membrane is slight, and then trigger miscellaneous
Matter is shaken, so as to reduce the probability that impurity blocks filter membrane；The infrared folder that tests the speed is clipped on woven hose, and woven hose passes through two wedges
Between shape block, if there is transfusion stopping, the information that the infrared folder that tests the speed is returned to microprocessor will appear from exception, pass through microprocessor
Device controls alarm equipment alarm, reminds medical personnel's timely processing；If occur infusing too fast, the infrared folder that tests the speed is returned to microprocessor
The information of device also will appear from exception, and microprocessor controlled motor starts, by gear ＆ rack structure drive two wedges towards by
Direction movement of staggering is walked, is gradually reduced the gap between wedge, so as to progressively compress woven hose, is reduced to transfusion speed
Normal level；When transfusion speed is slow, the information that the infrared folder that tests the speed is returned to microprocessor also will appear from exception, microprocessor control
Electric motor starting processed, two wedges are driven to be moved towards progressively coincidence direction by gear ＆ rack structure, between making between wedge
Gap gradually increases, and so as to progressively unclamp woven hose, is improved with reaching transfusion speed to the purpose of normal level.In summary, should
The transfusion device of structure, there is the advantages of adjusting drop number, monitoring and regulation transfusion dosage and filtering transfusion impurity, can be to transfusion
Stop, too fast, abnormal conditions slow and that transfusion is unstable of infusing of infusing make timely reaction, infused so as to effectively prevent
The generation of abnormal conditions in journey.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
